Definitions

  • the invention relates to an insulating formwork for the realization of concrete wall, in particular a formwork flattenable.
  • the formwork consists of two walls vertical and parallel, separated by the space where the concrete will be poured, each wall consisting of assembly of the polystyrene panels. Construction formwork works as follows. Rows are incorporated in which the panels are held between them by the tenon-mortise system. Angles are inserted into the grooves on the edge upper panels. A second row of angles is placed on the angles in place, wing against wing. Tie rods are inserted in holes provided for this effect in the horizontal wings of the angles, and thus connect the two parallel walls. These tie rods have right-angled plug-in ends in polystyrene panels parallel to the face vertical of the panels. A new row of panels is mounted on the assembly thus formed. Singing lower of the panels fits on the vertical wing of second row angles.
  • This system has the disadvantage of having to be implemented on site. It is not possible to realize factory pre-assembly, which would reduce the costs.
  • the mortise-tenon system at the end of each panel is binding because it does not allow to use cut panels. In addition, the holding of panels between them is not guaranteed, and they could deviate vertically when pouring concrete.
  • the shape of the panels is somewhat complex, which increases the cost of producing such panels. Through elsewhere, if one wishes to install such a facing only plasterboard or wooden panels, has no easy to use support. Indeed, the panels do not have sufficient tenacity to serve support, and the concrete wall is very hard, away from the visible surface, and requires little operations easy for fixing facing elements.
  • US-A-04936540 shows another method of concrete walls poured between panels which can be insulating panels such as polystyrene.
  • the spacing between the panels is maintained by plastic tie rods which pass through the panels placed in parallel.
  • One end of the tie rod is a dish perpendicular to the longitudinal direction the tie rod, which rests on the outside of the first sign.
  • the other end has a notch in which can accommodate a round iron or a key, this which ensures locking and prevents the spreading of panels.
  • EP-B-0491394 describes elements of formwork which are produced in the factory, and which have ways to reduce the space between two panels, which reduces their bulk and facilitates their transport. It can be for example a telescopic set of sliding elements in the others, and are housed in the thickness of the panels. It can also be chains or cables metallic. However, all the means exposed pass through the panels and do not allow to have of the outside surface of the free and uninsulated insulation roughness.
  • the invention which will be presented therefore aims to overcome these drawbacks. It aims to allow produce thermally formwork elements in the factory insulators, which will not require expensive tools, whose size will be limited to facilitate transport and storage, and the implementation of which will be simple and fast.

Finally, it aims to obtain a wall without elements protruding from the surface of the insulation and having a fixing support for a facing.
  • a formwork element is thus obtained which can be made in the factory. Indeed, the achievement of notches and insertion of staples according to the invention lends itself well to an application industrial. Similarly, it is possible to reduce the space between the panels by flattening the parallelogram. The interior faces of the panels are then almost contiguous, but offset. Volume then used by the formwork element is minimal.
  • the panels for the realization of the formwork element can be obtained from insulation boards such as polystyrene, which cut to the appropriate size and in which easily makes grooves and notches.

If the staples are far from the edge of the panel, the forces transmitted by the grooves and the rules decrease, and thus the deformation of panels also decreases. The curved exterior of the panel is then limited.

Abstract

The elements of the formwork are composed of two parallel insulating panels (1,2) connected by foldable fasteners (3). The rows of formwork elements are assembled along horizontal joints between rows by assembly rulers (4) which are inserted in longitudinal grooves (11,21,14,24) on each edge of the panels (12,22,3,23). An Independent claim is also included for the formwork used for the casting of a concrete wall.

Description

L'invention concerne un coffrage isolant pour la réalisation de mur en béton, en particulier un coffrage aplatissable.The invention relates to an insulating formwork for the realization of concrete wall, in particular a formwork flattenable.

Pour réaliser des murs en béton dans la construction de maison ou de bâtiment, on peut utiliser une méthode habituelle qui est de couler le béton entre des parois verticales. Ces parois peuvent être d'un type réutilisable ou d'un type perdu, et dans ce cas rester en place après le coulage du béton. Ces parois ont alors des fonctions supplémentaires, telle que l'isolation thermique par exemple. Dans ce cas, les parois sont constituées de panneaux isolants.To make concrete walls in the house or building construction we can use a usual method which is to pour concrete between vertical walls. These walls can be of a type reusable or of a lost type, and in this case remain in place after pouring the concrete. These walls then have additional functions, such as insulation thermal for example. In this case, the walls are made up of insulating panels.

On connaít des blocs en matière isolante qui comportent deux faces reliées par diverses méthodes. Ces blocs s'assemblent les uns avec les autres comme dans un jeu de construction et forment les deux parois reliées entre elles. Les chants de ces blocs ont des formes moulurées qui s'emboítent. Ces solutions nécessitent des outillages de moulage spécifiques et coûteux pour la fabrication des blocs. D'autre part, le volume que les blocs occupent est important par rapport à la surface de mur qu'ils permettent de réaliser, ce qui est très pénalisant pour le transport et le stockage.We know blocks of insulating material which have two faces connected by various methods. These blocks assemble with each other as in a construction set and form the two connected walls between them. The songs of these blocks have shapes molding that fit together. These solutions require specific and expensive molding tools for the block manufacturing. On the other hand, the volume that blocks occupy is important relative to the area of wall that they allow to realize, which is very penalizing for transport and storage.

On connaít déjà par le document EP-A1-0374064 un système de coffrage isolant à base de panneaux de polystyrène. Les chants verticaux de ces panneaux présentent une forme d'emboítement par tenon-mortaise. Les chants longitudinaux, qui s'étendent horizontalement, sont rainurés sur toute la longueur. Ces rainures sont destinées à recevoir des cornières, dont une aile s'insère dans la rainure. L'autre aile est orientée vers l'intérieur du mur.Document EP-A1-0374064 already discloses a insulating formwork system based on polystyrene. The vertical edges of these panels have a form of nesting mortise. The longitudinal edges, which extend horizontally, are grooved over the entire length. These grooves are intended to receive angles, including a wing fits into the groove. The other wing is oriented towards inside the wall.

Le coffrage est constitué par deux parois verticales et parallèles, séparées par l'espace où le béton sera coulé, chaque paroi étant constituée par l'assemblage des panneaux de polystyrène. La construction du coffrage s'opère de la façon suivante. Des rangées sont constituées dans lesquelles les panneaux sont tenus entre eux par le système tenon-mortaise. Des cornières filantes sont insérées dans les rainures sur le chant supérieur des panneaux. Une deuxième rangée de cornières est posée sur les cornières en place, aile contre aile. Des tirants sont insérés dans des trous prévus à cet effet dans les ailes horizontales des cornières, et relient ainsi les deux parois parallèles. Ces tirants possèdent des extrémités à angle droit qui s'enfichent dans les panneaux en polystyrène parallèlement à la face verticale des panneaux. Une nouvelle rangée de panneaux est montée sur l'ensemble ainsi constitué. Le chant inférieur des panneaux s'emboíte sur l'aile verticale des cornières de la deuxième rangée.The formwork consists of two walls vertical and parallel, separated by the space where the concrete will be poured, each wall consisting of assembly of the polystyrene panels. Construction formwork works as follows. Rows are incorporated in which the panels are held between them by the tenon-mortise system. Angles are inserted into the grooves on the edge upper panels. A second row of angles is placed on the angles in place, wing against wing. Tie rods are inserted in holes provided for this effect in the horizontal wings of the angles, and thus connect the two parallel walls. These tie rods have right-angled plug-in ends in polystyrene panels parallel to the face vertical of the panels. A new row of panels is mounted on the assembly thus formed. Singing lower of the panels fits on the vertical wing of second row angles.

Ce système présente l'inconvénient de devoir être mis en oeuvre sur place. Il n'est pas possible de réaliser de pré-assemblage en usine, ce qui permettrait de réduire les coûts. Le système de tenon-mortaise à l'extrémité de chaque panneau est contraignant, car il ne permet pas d'utiliser des panneaux coupés. De plus, la tenue des panneaux entre eux n'est pas garantie, et ils pourraient s'écarter dans le sens vertical lors du coulage du béton. La forme des panneaux est quelque peu complexe, ce qui alourdit le coût de réalisation de tels panneaux. Par ailleurs, si on souhaite mettre en place un parement tel que des plaques de plâtre ou des panneaux de bois, on ne dispose d'aucun support d'utilisation simple. En effet, les panneaux n'ont pas de ténacité suffisante pour servir de support, et le mur en béton est très dur, éloigné de la surface visible, et nécessite des opérations peu aisées pour la fixation d'éléments de parement.This system has the disadvantage of having to be implemented on site. It is not possible to realize factory pre-assembly, which would reduce the costs. The mortise-tenon system at the end of each panel is binding because it does not allow to use cut panels. In addition, the holding of panels between them is not guaranteed, and they could deviate vertically when pouring concrete. The shape of the panels is somewhat complex, which increases the cost of producing such panels. Through elsewhere, if one wishes to install such a facing only plasterboard or wooden panels, has no easy to use support. Indeed, the panels do not have sufficient tenacity to serve support, and the concrete wall is very hard, away from the visible surface, and requires little operations easy for fixing facing elements.

Le système décrit dans le document FR-A-2754285 reprend le même principe, mais en remplaçant les cornières appariées par un seul profilé en polymère rigide collé sur le bord supérieur du panneau. Ce profilé réalise un tenon destiné à coopérer avec une mortaise dans le bord inférieur du panneau. De plus, un profilé en U est inséré dans la mortaise pour réaliser un serrage du tenon et garantir un maintien relatif des panneaux. Les tirants de liaison entre les panneaux sont montés sur le chantier, comme dans le cas précédent.The system described in document FR-A-2754285 uses the same principle, but by replacing the angles matched by a single polymer profile rigid glued to the upper edge of the panel. This profile realizes a tenon intended to cooperate with a mortise in the lower edge of the panel. In addition, a profile in U is inserted into the mortise to tighten the post and guarantee relative support of the panels. The connecting rods between the panels are mounted on the site, as in the previous case.

Le document US-A-04936540 montre une autre méthode de réalisation de murs coulés en béton entre des panneaux qui peuvent être des panneaux isolants comme du polystyrène. L'écartement entre les panneaux est maintenu par des tirants en matière plastique qui traversent les panneaux placés parallèlement. Une extrémité du tirant est un plat perpendiculaire à la direction longitudinale du tirant, qui s'appuie sur la face extérieure du premier panneau. L'autre extrémité dispose d'une encoche dans laquelle peut se loger un fer rond ou une clavette, ce qui assure un verrouillage et empêche l'écartement des panneaux.US-A-04936540 shows another method of concrete walls poured between panels which can be insulating panels such as polystyrene. The spacing between the panels is maintained by plastic tie rods which pass through the panels placed in parallel. One end of the tie rod is a dish perpendicular to the longitudinal direction the tie rod, which rests on the outside of the first sign. The other end has a notch in which can accommodate a round iron or a key, this which ensures locking and prevents the spreading of panels.

Ce système présente l'avantage de ne pas nécessiter de pièces complexes et onéreuses, mais il doit être également mis en oeuvre sur le chantier et non en usine, il comporte donc sur ce point le même inconvénient que le système précédent. De plus, les extrémités des tirants dépassent après la réalisation du mur, et présentent un aspect peu esthétique et gênant pour les travaux de finition. Un mur réalisé par cette méthode ne présente pas non plus de facilité pour la fixation de parement.This system has the advantage of not requiring complex and expensive parts, but it must be also implemented on site and not in the factory, it therefore has the same disadvantage on this point as the previous system. In addition, the ends of the tie rods protrude after the completion of the wall, and present a unattractive and inconvenient appearance for the work of finish. A wall produced by this method does not have also no facility for fixing siding.

Le document EP-B-0491394 décrit des éléments de coffrage qui sont réalisés en usine, et qui disposent de moyens qui permettent de réduire l'espace qui sépare les deux panneaux, ce qui diminue leur encombrement et facilite leur transport. Ce peut être par exemple un ensemble télescopique d'éléments qui coulissent les uns dans les autres, et se logent dans l'épaisseur des panneaux. Ce peut être aussi des chaínettes ou des câbles métalliques. Cependant, tous les moyens exposés traversent les panneaux et ne permettent pas de disposer de la surface extérieure de l'isolant libre et sans aspérités.The document EP-B-0491394 describes elements of formwork which are produced in the factory, and which have ways to reduce the space between two panels, which reduces their bulk and facilitates their transport. It can be for example a telescopic set of sliding elements in the others, and are housed in the thickness of the panels. It can also be chains or cables metallic. However, all the means exposed pass through the panels and do not allow to have of the outside surface of the free and uninsulated insulation roughness.

L'invention qui va être présentée a donc pour but de pallier ces inconvénients. Elle vise à permettre de réaliser en usine des éléments de coffrage thermiquement isolants, qui ne nécessiteront pas d'outillage coûteux, dont l'encombrement sera limité pour faciliter le transport et le stockage, et dont la mise en oeuvre sera simple et rapide. Elle vise aussi à fournir un coffrage qui devra avoir une tenue suffisante lors du coulage du béton. Elle vise enfin à obtenir un mur sans éléments dépassant la surface de l'isolant et présentant un support de fixation pour un parement.The invention which will be presented therefore aims to overcome these drawbacks. It aims to allow produce thermally formwork elements in the factory insulators, which will not require expensive tools, whose size will be limited to facilitate transport and storage, and the implementation of which will be simple and fast. It also aims to provide formwork which should have sufficient hold when pouring the concrete. Finally, it aims to obtain a wall without elements protruding from the surface of the insulation and having a fixing support for a facing.

Avec ces objectifs en vue, l'invention a pour objet un élément de coffrage isolant destiné au coulage de mur en béton, comprenant :

  • un premier et un deuxième panneau, au moins un des panneaux étant en matière isolante, chaque panneau étant muni sur au moins un premier chant longitudinal d'une pluralité d'encoches,
  • une pluralité d'agrafes de liaison comportant chacune une première et une deuxième extrémité et une âme qui relie les dites extrémités, lesquelles extrémités ont une forme adaptée pour s'insérer dans les encoches, la première extrémité s'engageant dans une encoche du premier panneau, la deuxième extrémité s'engageant dans une encoche du deuxième panneau.
Selon l'invention, chaque panneau comporte des rainures longitudinales sur le premier et un deuxième chant, parallèle au premier chant, des règles d'assemblage s'insérant dans les rainures de panneaux superposés.With these objectives in view, the invention relates to an insulating formwork element intended for pouring concrete walls, comprising:
  • a first and a second panel, at least one of the panels being of insulating material, each panel being provided on at least a first longitudinal edge with a plurality of notches,
  • a plurality of connecting clips each comprising a first and a second end and a core which connects said ends, which ends have a shape adapted to fit into the notches, the first end engaging in a notch of the first panel , the second end engaging a notch in the second panel.
According to the invention, each panel has longitudinal grooves on the first and a second edge, parallel to the first edge, assembly rules inserted in the grooves of superimposed panels.

On obtient ainsi un élément de coffrage qui peut être fabriqué en usine. En effet, la réalisation des encoches et l'insertion des agrafes conformément à l'invention se prêtent bien à une application industrielle. De même, il est possible de réduire l'espace qui sépare les panneaux en aplatissant le parallélogramme. Les faces intérieures des panneaux sont alors quasiment jointives, mais décalées. Le volume utilisé alors par l'élément de coffrage est minimal.A formwork element is thus obtained which can be made in the factory. Indeed, the achievement of notches and insertion of staples according to the invention lends itself well to an application industrial. Similarly, it is possible to reduce the space between the panels by flattening the parallelogram. The interior faces of the panels are then almost contiguous, but offset. Volume then used by the formwork element is minimal.

De plus, les panneaux pour la réalisation de l'élément de coffrage peuvent être obtenus à partir de plaques d'isolant tel que du polystyrène, que l'on découpe à la taille adéquate et dans lesquelles on réalise facilement les rainures et les encoches. Ces plaques sont produites en grande série et leur coût est très avantageux. Il n'y a pas lieu d'investir dans un outillage de moulage coûteux que nécessite par exemple la fabrication des blocs en matière isolante à chants moulurés. De même, la forme à réaliser est plus simple que dans le cas du document EP-A1-0374064. Il n'est pas nécessaire non plus de souder ou coller des profilés comme dans le cas du document FR-A-2754285.In addition, the panels for the realization of the formwork element can be obtained from insulation boards such as polystyrene, which cut to the appropriate size and in which easily makes grooves and notches. These plates are mass produced and their cost is very advantageous. There is no need to invest in a expensive molding tools required for example by production of insulating blocks with edges molded. Likewise, the shape to be made is simpler than in the case of document EP-A1-0374064. He is not no more welding or gluing profiles as in the case of document FR-A-2754285.

Par ailleurs, la règle qui s'étend au niveau des joints horizontaux entre panneaux sans être apparente constitue un support pour fixer par exemple par vissage des éléments à rapporter contre le mur, tels que des parements en plaque de plâtre, des panneaux de bois ou tout type de bardage. Elle réalise également l'étanchéité du coffrage le long des joints horizontaux, ce qui évite qu'il ne se produise des fuites de laitance lors du coulage du béton.Furthermore, the rule which extends to the level of horizontal joints between panels without being visible constitutes a support for fixing for example by screwing items to bring against the wall, such as plasterboard siding, wood panels or any type of cladding. It also performs sealing formwork along the horizontal joints, which avoids there should be leakage of milt during the pouring concrete.

De manière préférentielle, l'âme des agrafes est sensiblement plane, les extrémités des agrafes sont en forme de plats perpendiculaires à l'âme des agrafes et que les encoches ont une forme en T pour que l'âme des agrafes soit perpendiculaire au premier chant des panneaux. Les agrafes sont ainsi très bien ancrées dans les panneaux, avec une bonne résistance de retenue des panneaux contre les efforts dus à la pression du béton.Preferably, the core of the staples is substantially flat, the ends of the staples are form of dishes perpendicular to the core of the staples and that the notches have a T shape so that the soul of staples be perpendicular to the first edge of the panels. The staples are thus very well anchored in the panels, with a good resistance to retaining panels against stresses due to concrete pressure.

Selon un premier mode de réalisation, les extrémités des agrafes s'engagent dans les encoches sur une distance supérieure à la hauteur des agrafes. Le fait que les agrafes soient enfoncées profondément dans les encoches les éloignent du chant du panneau. Cette position est plus favorable à la résistance mécanique des panneaux que si les agrafes étaient au bord du panneau. En effet, les efforts sur un panneau dus à la pression du béton coulé entre les panneaux sont repris d'une part par les agrafes et d'autre part par les rainures et les règles d'assemblage. Si les agrafes sont éloignées du bord du panneau, les efforts transmis par les rainures et les règles diminuent, et ainsi la déformation des panneaux diminue également. Le bombé extérieur du panneau est alors limité.According to a first embodiment, the ends of the staples engage in the notches on a distance greater than the height of the staples. The fact the staples are pushed deep into the notches keep them away from the edge of the panel. This position is more favorable to the mechanical strength of panels only if the staples were at the edge of the panel. Indeed, the forces on a panel due to the pressure of the concrete poured between the panels is taken up on the one hand by staples and secondly by the grooves and assembly rules. If the staples are far from the edge of the panel, the forces transmitted by the grooves and the rules decrease, and thus the deformation of panels also decreases. The curved exterior of the panel is then limited.

Dans le cas où l'élément de coffrage comporterait des encoches et des agrafes le long des chants supérieur et inférieur, les efforts dus à la pression du béton sont entièrement repris de manière interne à l'élément de coffrage par les agrafes. Aucun effort n'est transmis par les rainures et les règles d'assemblage d'un élément de coffrage à l'autre. De plus, il est possible d'optimiser la distance des agrafes par rapport aux chants longitudinaux pour minimiser le bombé des panneaux. Les agrafes peuvent être disposées soit en alternance d'un chant à l'autre, soit de manière symétrique.If the formwork element includes notches and staples along the upper edges and lower, the stresses due to the pressure of the concrete are fully internal to the element of formwork by staples. No effort is transmitted by the grooves and the assembly rules of an element of formwork to another. In addition, it is possible to optimize distance of staples from edges longitudinal to minimize the curvature of the panels. The staples can be arranged either alternately with a song to another, either symmetrically.

Dans ce premier mode de réalisation, la règle peut être placée dans l'épaisseur du panneau à une distance libre par rapport à la face extérieure. Plus particulièrement, soit la règle est située au-dessus du bord de l'âme des agrafes, soit dans le même plan que les extrémités des agrafes.In this first embodiment, the rule can be placed in the thickness of the panel at a distance free with respect to the external face. More particularly, either the ruler is located above the edge of the staple core, in the same plane as the ends of staples.

Dans un deuxième mode de réalisation, les extrémités des agrafes de liaison sont munies de moyens de liaison avec le deuxième chant d'un panneau adjacent pour empêcher le déplacement longitudinal du panneau adjacent. Ces moyens de liaison peuvent être constitués par le prolongement de l'extrémité de l'agrafe qui pénètre dans le deuxième chant du panneau adjacent au moment de la pose. Ces moyens de liaison participent également à la reprise des efforts entre panneaux dus à la pression du béton.In a second embodiment, the ends of the connecting clips are provided with means connecting with the second edge of an adjacent panel to prevent longitudinal movement of the panel adjacent. These connecting means can be constituted by extending the end of the clip which enters the second edge of the panel adjacent to the time of installation. These means of connection participate also the resumption of forces between panels due to concrete pressure.

Selon une caractéristique complémentaire, les agrafes de liaison ont leurs directions longitudinales parallèles entre elles et perpendiculaires aux panneaux, ainsi que des moyens d'articulation à proximité de chacun des premier et deuxième panneaux, les âmes des agrafes formant avec les panneaux un parallélogramme dont les sommets sont les moyens d'articulation, de telle sorte que l'un des panneaux peut être rabattu sur l'autre panneau en déformant les angles du parallélogramme pour réduire l'espace qui sépare les panneaux. De cette manière, il est possible de réduire l'espace qui sépare les panneaux en aplatissant le parallélogramme. Les faces intérieures des panneaux sont alors quasiment jointives, mais décalées longitudinalement. Le volume utilisé alors par l'élément de coffrage est minimal.According to an additional characteristic, the connecting clips have their longitudinal directions parallel to each other and perpendicular to the panels, as well as means of articulation close to each of the first and second panels, the souls of the staples forming with the panels a parallelogram whose vertices are the means of articulation, so that one of the panels can be folded down over the other panel by distorting the angles of the parallelogram to reduce the space between the panels. Of this way it is possible to reduce the space that separates the panels by flattening the parallelogram. The faces interior of the panels are then almost contiguous, but offset longitudinally. The volume used then by the formwork element is minimal.

Selon un mode de réalisation préférentiel, les agrafes de liaison ont une âme sensiblement plane, les moyens d'articulation sont constitués par un amincissement de l'âme selon une droite sensiblement parallèle à l'un des panneaux.According to a preferred embodiment, the connecting clips have a substantially planar core, the articulation means are constituted by a thinning of the core along a substantially straight line parallel to one of the panels.

La règle peut avantageusement être munie de moyens de liaison avec les panneaux. De cette façon, on obtient une liaison ferme entre les panneaux pour les empêcher de s'écarter l'un de l'autre.The rule can advantageously be provided with means connecting with the panels. This way we get a firm bond between the panels to prevent them from move away from each other.

L'invention a aussi pour objet un coffrage pour le coulage d'un mur en béton, caractérisé en ce qu'il est constitué d'un alignement et d'un empilement d'une pluralité d'éléments de coffrage, les premiers panneaux étant jointifs et coplanaires, et les deuxièmes panneaux étant jointifs et coplanaires, et les rainures longitudinales sur les premiers chants étant dans l'alignement les unes des autres, les rainures longitudinales sur les deuxièmes chants étant dans l'alignement les unes des autres. La règle d'assemblage est insérée dans les rainures en alignement des panneaux adjacents, reliant le premier chant d'un panneau au second chant d'un autre panneau empilé et s'étendant sur l'alignement de plusieurs panneaux.The invention also relates to a formwork for the pouring a concrete wall, characterized in that it is consisting of an alignment and a stack of multiple formwork elements, the first panels being contiguous and coplanar, and the second panels being contiguous and coplanar, and the grooves longitudinal on the first songs being in alignment of each other, the grooves longitudinal on the second edges being in alignment with each other. The assembly rule is inserted into the grooves in alignment with the panels adjacent, connecting the first song of a panel to second song from another stacked panel spanning the alignment of several panels.

L'assemblage d'éléments de coffrage conformes à l'invention permet d'obtenir rapidement et facilement un coffrage isolant dans lequel on coulera du béton pour réaliser un mur. Les opérations sur le chantier sont relativement limitées, car elles consistent à mettre en place les éléments de coffrage et à insérer la règle d'assemblage. De plus, on obtient un coffrage dont aucun élément ne dépasse de la face visible. La règle est, de manière avantageuse, continue sur une grande longueur. Ainsi, contrairement à la solution du document FR-A-2754285, il n'y a pas de rupture de l'élément de liaison longitudinal au niveau des jonctions entre panneaux d'une même rangée. On obtient une meilleure résistance de l'assemblage ainsi réalisé.The assembly of formwork elements in accordance with the invention makes it possible to quickly and easily obtain a insulating formwork in which concrete will be poured make a wall. Site operations are relatively limited because they consist of places the formwork elements and insert the ruler assembly. In addition, we obtain a formwork of which none element does not protrude from the visible face. The rule is, to advantageously, continuous over a great length. So unlike the document solution FR-A-2754285, there is no rupture of the element of longitudinal connection at the junctions between panels of the same row. We get better resistance of the assembly thus produced.

Un élément de coffrage conforme à l'invention selon un premier mode de réalisation apparaít sur la figure 1. Il est constitué de deux panneaux 1, 2, et de plusieurs agrafes de liaison 3. Les dimensions des panneaux qui vont suivre sont données à titre d'exemple et ne doivent pas être considérées comme limitatives. La hauteur des panneaux peut être comprise entre 200 et 600 mm. Leur longueur peut être comprise entre 1 et 4 m et leur épaisseur entre 40 et 150 mm. La matière des panneaux est typiquement du polystyrène expansé, de densité comprise entre 25 et 35 kg/m3 . Ce peut être également du polystyrène extrudé ou de la mousse polyuréthane. Les panneaux peuvent être obtenus à partir de simples plaques. Chaque panneau comporte des rainures 14, 24 sur le bord inférieur 13, 23 et des rainures 11, 21 sur le bord supérieur 12, 22. Il comporte une série d'encoches 10, 20, montrées sur la figure 6, qui se répartissent sur le bord supérieur, du côté de la face intérieure 16, 26. Ces encoches ont une forme de T en coupe selon un plan horizontal. Les ailes 101 du T de l'encoche 10 sont situées dans le prolongement des rainures 11, 21. Les encoches peuvent être réalisées par un outil chauffant qui pénètre dans le bord d'un panneau et fait fondre la matière. Les rainures peuvent être réalisées par rainurage avec un outil de coupe, ou par une découpe à l'aide d'un fil chauffant.A formwork element according to the invention according to a first embodiment appears in Figure 1. It consists of two panels 1, 2, and several connecting clips 3. The dimensions of the panels which will follow are given as example and should not be considered as limiting. The height of the panels can be between 200 and 600 mm. Their length can be between 1 and 4 m and their thickness between 40 and 150 mm. The material of the panels is typically expanded polystyrene, with a density between 25 and 35 kg / m 3 . It can also be extruded polystyrene or polyurethane foam. The panels can be obtained from simple plates. Each panel has grooves 14, 24 on the lower edge 13, 23 and grooves 11, 21 on the upper edge 12, 22. It has a series of notches 10, 20, shown in Figure 6, which are distributed over the upper edge, on the side of the inner face 16, 26. These notches have a T shape in section along a horizontal plane. The wings 101 of the T of the notch 10 are located in the extension of the grooves 11, 21. The notches can be produced by a heating tool which penetrates into the edge of a panel and melts the material. The grooves can be made by grooving with a cutting tool, or by cutting using a heating wire.

L'agrafe 3 représentée sur les figures 2 et 3 comporte deux extrémités 30, 31 en forme de plat, reliées par une âme 36 plane. Deux amincissements 34, 35 de faible largeur sur l'âme 36 constituent des moyens d'articulation. Chaque extrémité 30, 31 comporte des ergots 32, 33 le long du bord inférieur.Clip 3 shown in Figures 2 and 3 has two ends 30, 31 in the form of a flat, connected by a flat core 36. Two thinning 34, 35 of small width on the core 36 constitute means of articulation. Each end 30, 31 has pins 32, 33 along the lower edge.

Comme on le voit sur la figure 5, les encoches 10, 20 reçoivent les agrafes de liaison 3. La profondeur des encoches est suffisante pour que les agrafes puissent être enfoncées jusqu'à ce qu'une distance d'enfoncement e soit atteinte entre le bord supérieur des extrémités 30, 31 des agrafes et le premier chant 12. De la sorte, les rainures 11, 21 restent libres. La largeur des ergots 32, 33 est plus importante que celle de l'encoche, de telle sorte que les ergots déforment les flancs de l'encoche et s'accrochent à ceux-ci pour éviter tout mouvement de retrait.As can be seen in FIG. 5, the notches 10, 20 receive the connecting staples 3. The depth of the notches is sufficient for the staples to be able to be inserted until a insertion distance e is reached between the upper edge of the ends 30, 31 of the staples and the first edge 12. In this way, the grooves 11, 21 remain free. The width of the pins 32, 33 is greater than that of the notch, so that the pins deform the sides of the notch and cling to them to avoid any movement of withdrawal.

Si besoin, pour des raisons de résistance mécanique ou de facilité de manipulation, il est possible que des agrafes soient mises en place le long des bords inférieurs 13, 23 des panneaux, éventuellement en quantité réduite. La technique de fixation est la même, de manière symétrique. Cette configuration est également montrée sur la figure 5.If necessary, for reasons of mechanical resistance or ease of handling, it is possible that staples are placed along the edges lower panels 13, 23, possibly in reduced quantity. The fixing technique is the same, symmetrically. This configuration is also shown in Figure 5.

Les âmes 36 des agrafes 3 sont disposées parallèlement les unes aux autres. La distance entre deux agrafes successives est comprise entre 100 et 400 mm.The cores 36 of the staples 3 are arranged parallel to each other. The distance between two successive staples is between 100 and 400 mm.

La règle 4 se présente sous la forme d'un profilé en matière plastique telle que du polystyrène rigide ou du polypropylène. La section d'une telle règle apparaít sur la figure 4. La règle comporte une âme 40 et des ergots 41, 42. L'épaisseur de l'âme peut être de 1 à 4 mm, tandis que sa largeur peut être de 50 à 100 mm. Sa longueur est déterminée par les conditions de transport et de manipulation. Elle peut être de 1 à 6 m. Les ergots, qui s'étendent sur toute la longueur de la règle, ont une largeur qui dépasse celle des rainures 11, 14, 21, 24 de telle sorte que, lorsqu'on insère la règle dans une rainure, les ergots déforment les flancs de la rainure et s'accrochent à ceux-ci en cas de mouvement de retrait.Rule 4 is in the form of a profile plastic such as rigid polystyrene or polypropylene. The section of such a rule appears in FIG. 4. The rule comprises a core 40 and pins 41, 42. The thickness of the core can be from 1 to 4 mm, while its width can be from 50 to 100 mm. Her length is determined by transport conditions and manipulation. It can be from 1 to 6 m. The pins, which extend over the entire length of the rule, have a width which exceeds that of the grooves 11, 14, 21, 24 so that when the rule is inserted in a groove, the lugs deform the sides of the groove and cling to them in the event of movement of withdrawal.

Dans une variante du premier mode de réalisation de l'invention, les agrafes sont positionnées plus dans la direction de l'épaisseur des panneaux, sans que la position des rainures et des règles d'assemblage ne soit modifiée. Dans ce cas, la règle 4 se trouve au-dessus non pas de l'extrémité 30, 31 des agrafes mais du bord 37 de l'âme des agrafes, situé entre l'amincissement 34, 35 et l'extrémité 30, 31, comme le montre la figure 7.In a variant of the first embodiment of the invention, the staples are positioned more in the direction of the thickness of the panels, without the position of the grooves and assembly rules either modified. In this case, rule 4 is above no not from the end 30, 31 of the staples but from the edge 37 of the core of the staples, located between the thinning 34, 35 and the end 30, 31, as shown in FIG. 7.

Dans un deuxième mode de réalisation, montré sur la figure 8, les encoches reçoivent des agrafes de liaison 3' de telle sorte que le bord supérieur 37 de l'âme des agrafes 3' arrive au niveau du bord supérieur 12, 22 des panneaux. Les ailes des encoches sont situées entre la rainure 11, 21 et la face intérieure 16, 26.In a second embodiment, shown on the figure 8, the notches receive connecting staples 3 'so that the upper edge 37 of the core of the staples 3 'arrives at the upper edge 12, 22 of panels. The wings of the notches are located between the groove 11, 21 and the inner face 16, 26.

L'agrafe 3' représentée sur la figure 9 comporte deux extrémités 30, 31 qui se présentent sous la forme de plats sensiblement parallèles, reliées par une âme plane 36 perpendiculaire aux extrémités 30, 31. Les extrémités s'étendent au-delà du bord supérieur 37 de l'âme, par des pointes 38. L'âme comporte deux amincissements 34, 35 de faible largeur et qui s'étendent parallèlement aux plats. Ces amincissements constituent les moyens d'articulation.The clip 3 'shown in Figure 9 includes two ends 30, 31 which are in the form of substantially parallel dishes, connected by a flat core 36 perpendicular to the ends 30, 31. The ends extend beyond the upper edge 37 of the core, by points 38. The core has two thinning 34, 35 of small width and which extend parallel to the dishes. These thinning constitute the means of articulation.

Chaque extrémité comporte des ergots 32, 33 le long du bord inférieur et éventuellement le long du bord supérieur. La largeur des ergots est plus importante que celle de l'encoche, de telle sorte que les ergots déforment les flancs de l'encoche et s'accrochent à ceux-ci pour éviter tout mouvement de retrait. Les ergots peuvent s'étendre des deux côtés des bords des extrémités 30, 31. Préférentiellement, comme représenté sur la figure 9, ils sont réalisés seulement du côté intérieur, ce qui permet par exemple, en variante de la réalisation de la figure 8, de placer la règle directement en contact avec les dits plats d'extrémités, autrement dit d'avoir les ailes 101 des encoches 10, 20 sensiblement confondus avec les rainures 11, 21 recevant les règles 4.Each end has lugs 32, 33 along from the bottom edge and possibly along the edge superior. The width of the pins is greater than that of the notch, so that the pins deform and cling to the sides of the notch to avoid any withdrawal movement. The pins can extend on both sides of the edges of the ends 30, 31. Preferably, as shown in the Figure 9, they are made only from the inside, which allows for example, as a variant of the embodiment of figure 8, to place the rule directly in contact with the so-called end plates, in other words to have the wings 101 of the notches 10, 20 substantially merged with the grooves 11, 21 receiving the rules 4.

Pour réaliser un coffrage de mur avec les éléments conforme à l'invention, on procède de la manière suivante.To make a wall formwork with the elements according to the invention, one proceeds in the manner next.

Sur une base 7 destinée à recevoir le mur, telle qu'une dalle ou une semelle filante, on dispose des rails ou des cornières 6 dans l'alignement prévu du mur, selon une technique connue en soi. Aux angles, on met en place une cornière d'angle 5 verticale, maintenue en place par des contrefiches ou raidisseurs 51, 52, comme le montre la figure 11.On a base 7 intended to receive the wall, such that a slab or a strip base, we have rails or angles 6 in the planned alignment of the wall, depending a technique known per se. At the corners, we set up a vertical angle angle 5, held in place by struts or stiffeners 51, 52, as shown Figure 11.

Ensuite, on dispose sur ces rails ou cornières une première rangée d'éléments de coffrage conformes à l'invention entre les cornières d'angle. On coupe les panneaux à la bonne longueur si nécessaire. On insère une règle 4 dans les rainures 11, 21 sur toute la longueur de chaque rangée de panneaux. La règle d'assemblage est positionnée au fond de la rainure de telle sorte qu'elle se trouve au-dessus des extrémités 30, 31 des agrafes ou du bord 37. On prend soin de mettre les chants verticaux des panneaux adjacents des éléments de coffrage bien jointifs l'un contre l'autre. On dispose alors une nouvelle rangée d'éléments de coffrage en insérant les rainures 14, 24 sur la partie de la règle restant apparente. On prend soin de placer les joints verticaux décalés d'une rangée à l'autre. Dans le deuxième mode de réalisation, des moyens de liaisons avec le deuxième chant sont constitués par les pointes 38 des agrafes 3' qui dépassent des bords supérieurs 12, 22 des panneaux, qui s'incrustent dans le bord inférieur 13, 23 du panneau placé au-dessus et qui réalisent un blocage longitudinal des panneaux entre-eux. Ce blocage participe à l'étanchéité des joints verticaux en évitant le déplacement relatif des panneaux.Then there is on these rails or angles first row of formwork elements conforming to the invention between the corner angles. We cut them panels at the correct length if necessary. We insert a rule 4 in the grooves 11, 21 over the entire length of each row of panels. The assembly rule is positioned at the bottom of the groove so that it is located above the ends 30, 31 of the staples or edge 37. We take care to put the vertical edges adjacent panels of the formwork elements well joined against each other. We then have a new row of formwork elements by inserting the grooves 14, 24 on the part of the ruler remaining related. We take care to place the vertical joints shifted from one row to another. In the second mode of realization, means of connection with the second edges are formed by the points 38 of the staples 3 ' which protrude from the upper edges 12, 22 of the panels, which are embedded in the lower edge 13, 23 of the panel placed above and which realize a longitudinal blocking signs between them. This blockage contributes to the tightness of the vertical joints avoiding the relative displacement of the panels.

Les panneaux des éléments sont mis en appui les uns contre les autres dans le sens horizontal et le sens vertical. De la même manière que pour la première rangée, on insère une règle dans les rainures 11, 21 de chaque rangée de panneaux. Par l'ajout d'autres rangées, on obtient ainsi deux parois parallèles reliées par des agrafes, et qui définissent entre elles un espace dans lequel le béton pourra être coulé.The panels of the elements are supported one against others in the horizontal direction and the direction vertical. In the same way as for the first row, we insert a rule in the grooves 11, 21 of each row of panels. By adding other rows, we thus obtains two parallel walls connected by staples, and which define a space between them which concrete can be poured.

Les rangées successives sont montées ainsi. Comme on le voit sur la figure 11, pour assurer la stabilité et la verticalité du coffrage, on met en place des stabilisateurs 8 à une distance régulière, soit environ 1,50 m, sur un côté. La liaison du coffrage aux stabilisateurs 8 est réalisée par exemple par des vis, qui traversent le stabilisateur et viennent se visser dans les règles 4. Le stabilisateur comporte des moyens d'ajustage 80 de la verticalité. Les montants du stabilisateur sont articulés sur la base fixée sur la dalle ou le sol, ainsi que le montant comportant les moyens d'ajustage.The successive rows are mounted as well. As seen in Figure 11, to provide stability and the verticality of the formwork, we put in place 8 stabilizers at a regular distance, about 1.50 m, on one side. The connection of the formwork to stabilizers 8 is produced for example by screws, which cross the stabilizer and come to screw in rules 4. The stabilizer includes means adjustment 80 of the verticality. The amounts of stabilizer are articulated on the base fixed on the slab or the ground, as well as the amount including the means of adjustment.

Si nécessaire, des armatures en acier peuvent être disposées entre les parois du coffrage. Les armatures sont déterminées par les règles de calcul en vigueur concernant le béton armé. Des crans 39 sont alors prévues sur les agrafes pour y loger les barres horizontales des armatures et maintenir une distance constante entre les armatures et les faces intérieures 16, 26 du coffrage.If necessary, steel reinforcements can be arranged between the walls of the formwork. The frames are determined by the calculation rules in force regarding reinforced concrete. Notches 39 are then provided on the staples to accommodate the horizontal bars of the reinforcements and maintain a constant distance between reinforcements and the inner faces 16, 26 of the formwork.

La mise en place du coffrage peut être réalisée en plusieurs phases ou sur la hauteur totale d'un niveau. On peut par exemple monter le coffrage et couler sur une hauteur correspondant à la base des fenêtres puis monter le coffrage plus haut. On peut également monter le coffrage sur la hauteur totale d'un niveau. Dans ce cas, on coule le béton à l'aide d'une pompe à béton pour éviter qu'il ne chute de trop haut et ne génère des pressions qui risqueraient d'écarter les parois du coffrage. Le coulage du béton est effectué par exemple par strates de hauteur 0,4 à 1 m, espacées d'un intervalle de temps de 20 min au minimum. La pression sur les éléments inférieurs est ainsi réduite quand le béton a déjà pu commencer sa prise.The formwork can be installed in several phases or over the total height of a level. We can for example mount the formwork and pour on a height corresponding to the base of the windows then mount the formwork higher. You can also mount the formwork on the total height of a level. In that case, concrete is poured using a concrete pump to prevent it from falling too high and generating pressures that could spread the walls of the formwork. Concrete is poured for example by strata 0.4 to 1 m high, spaced one time interval of 20 min minimum. The pressure on the lower elements is thus reduced when the concrete has already been able to start taking.

Le volume occupé par les éléments de coffrage est minimisé pour le transport par les moyens d'articulation des agrafes. En effet, comme on le voit sur la figure 12, les âmes 36 de deux agrafes 3 successives forment avec les panneaux 1, 2 un parallélogramme dont les sommets sont des moyens d'articulation 34, 35. On peut replier le parallélogramme ainsi formé dans le sens de la flèche F pour amener les faces intérieures 16, 26 des panneaux quasiment en contact l'un avec l'autre, avec un décalage longitudinal.The volume occupied by the formwork elements is minimized for transport by means of articulation staples. Indeed, as seen in Figure 12, the webs 36 of two successive clips 3 form with panels 1, 2 a parallelogram with vertices are articulation means 34, 35. We can fold the parallelogram thus formed in the direction of arrow F to bring the interior faces 16, 26 of the panels almost in contact with each other, with an offset longitudinal.

La présente invention n'est pas limitée à l'exemple décrit. Un des panneaux 1, 2 pourra par exemple être réalisé en bois contre-plaqué ou aggloméré. Les agrafes peuvent être enfoncées dans les encoches jusqu'à mi-hauteur des panneaux. Elle peuvent ne pas être articulées. The present invention is not limited to the example described. One of the panels 1, 2 could for example be made of plywood or chipboard. Staples can be inserted into the notches up to mid-height Signs. They may not be articulated.

Par ailleurs, la forme des extrémités des agrafes n'est pas nécessairement plane. Elle peut être cylindrique ou de section carrée. Des ergots peuvent également s'étendre dans le sens longitudinal de l'âme de l'agrafe, entre les amincissements 34, 35 et les extrémités 30, 31, le long du bord inférieur de l'âme.Furthermore, the shape of the ends of the staples is not necessarily flat. She may be cylindrical or square section. Lugs can also extend in the longitudinal direction of the soul of the clip, between the thinnings 34, 35 and the ends 30, 31, along the lower edge of the core.

D'autre part, l'âme des agrafes n'est pas forcément rigide, mais elle peut être souple.On the other hand, the soul of the staples is not necessarily rigid, but it can be flexible.
