Abstract

Units, particularly formwork units, adapted, for example, for the construction of walls, are each provided with at least one portion of one and the same swivelling device (12) in the form of a male element (14) and of a female element (16) in such a manner that the joining together of two units enables the swivelling device (12) to be produced and thus permits the rotation, in relation to one another, of two juxtaposed units, in such a manner as to effect changes of direction between them. <IMAGE>

Description

La présente invention a pour objet des blocs, notamment de coffrage, destinés, par exemple, à la réa­lisation de murs, constitués principalement par au moins une paroi verticale et par, le cas échéant, des entre­toises reliant entre elles les parois verticales.The present invention relates to blocks, in particular formwork, intended, for example, for the production of walls, mainly consisting of at least one vertical wall and, if necessary, spacers connecting the vertical walls together.

Actuellement, on utilise très souvent des blocs de coffrage pour la réalisation de murs, principa­lement dans le domaine du bâtiment. Ces blocs de coffra­ge sont, en général, en polystyrène expansé ayant subi un traitement d'ignifugation, et comportent, en général, deux parois verticales reliées entre elles par des en­tretoises. Le volume intérieur ainsi délimité est rempli de béton en utilisant, par exemple, une pompe à béton.Currently, formwork blocks are very often used for making walls, mainly in the building sector. These formwork blocks are, in general, made of expanded polystyrene having undergone a fireproofing treatment, and generally comprise two vertical walls connected to one another by spacers. The interior volume thus delimited is filled with concrete using, for example, a concrete pump.

Mais, les blocs existants présentent l'incon­vénient de ne pas être adaptés dès qu'il s'agit de pro­céder à un changement de direction dans le mur, c'est-à-­dire lorsqu'il s'agit de réaliser des angles dans le mur ou encore des arrondis, etc... On a d'abord songé à con­cevoir, pour chaque angle correspondant à un changement de direction souhaité, un bloc de coffrage spécifique, ce qui avait pour résultat qu'il était nécessaire de fa­briquer autant de blocs de coffrage que de changements de direction souhaités ! On a alors utilisé les blocs de coffrage classiques pour réaliser ces changements de di­rection, mais il était malgré tout nécessaire d'avoir recours, à chaque fois, à une pièce spécifique supplé­mentaire pour fermer l'ouverture créée par l'angle formé entre les deux blocs de coffrage, la dimension et la forme de cette pièce spécifique étant, bien entendu, fonction de l'ouverture désirée. En outre, il était éga­lement nécessaire d'avoir recours à des pièces spécifi­ques en forme de coins lorsqu'il était souhaité de réa­ liser des angles droits entre deux parois d'un même mur. Par exemple, lors d'un angle droit dans un mur où il était souhaité d'avoir un arrondi à l'extérieur et un angle droit à l'intérieur, deux pièces supplémentaires étaient nécessaires, à savoir une pièce droite et une pièce gauche.However, existing blocks have the disadvantage of not being suitable when it comes to making a change of direction in the wall, that is to say when it comes to making angles in the wall or rounding, etc. We first thought of designing, for each angle corresponding to a desired change in direction, a specific formwork block, which had the result that it was necessary to manufacture as much formwork blocks as many changes of direction as desired! We then used the classic formwork blocks to make these changes of direction, but it was still necessary to use, each time, an additional specific piece to close the opening created by the angle formed between the two formwork blocks, the size and shape of this specific part being, of course, a function of the desired opening. In addition, it was also necessary to have recourse to specific pieces in the form of corners when it was desired to react. read right angles between two walls of the same wall. For example, at a right angle in a wall where it was desired to have a round on the outside and a right angle on the inside, two additional pieces were needed, namely a right piece and a left piece.

Par ailleurs, l'assemblage entre eux de tels blocs ne s'effectue que difficilement et sans grande sé­curité, notamment au niveau de l'étanchéité. Le disposi­tif d'assemblage le plus performant à l'heure actuelle est constitué par des ergots situés sur la tranche supé­rieure de chaque paroi verticale, ces ergots venant s'emboîter dans des orifices situés sur la tranche infé­rieure de chaque paroi verticale, la dimension de chaque ergot correspondant exactement à celle de chaque orifi­ce. Néanmoins, un tel dispositif ne permet pas de pal­lier les inconvénients décrits ci-dessus et ne permet pas, notamment, d'empêcher les blocs de coffrage de re­monter lors du coulage du béton.Furthermore, the assembly between them of such blocks is carried out only with difficulty and without great security, in particular at the level of sealing. The most efficient assembly device at present consists of lugs located on the upper edge of each vertical wall, these lugs coming to fit into holes located on the lower edge of each vertical wall, the dimension of each lug corresponding exactly to that of each orifice. However, such a device does not overcome the drawbacks described above and does not, in particular, prevent the formwork blocks from going up during the pouring of the concrete.

Le problème général à résoudre par l'objet de la présente invention est donc de réaliser des blocs permettant de réaliser tous les changements de direction souhaités sans avoir recours à aucune pièce spécifique supplémentaire, le nombre de blocs de structures diffé­rentes devant être aussi réduit que possible. Par ail­leurs, les blocs doivent s'assembler parfaitement entre eux sans aucun risque de désolidarisation ou de fuite.The general problem to be solved by the object of the present invention is therefore to produce blocks making it possible to carry out all the desired changes of direction without having to use any additional specific part, the number of blocks of different structures having to be as small as possible . In addition, the blocks must fit perfectly together without any risk of separation or leakage.

Selon la présente invention, ce problème est résolu en ce que les blocs, constitués principalement par au moins une paroi verticale et par, le cas échéant, des entretoises reliant entre elles les parois vertica­les, sont pourvus chacun d'au moins une partie d'un même dispositif de pivotement sous la forme d'un élément mâle et d'un élément femelle, de telle manière que l'assem­blage de deux blocs entre eux permette précisément de réaliser un tel dispositif de pivotement et autorise ainsi la rotation, l'un par rapport à l'autre, de deux blocs juxtaposés, de façon à réaliser des changements de direction entre eux.According to the present invention, this problem is solved in that the blocks, mainly consisting of at least one vertical wall and, if necessary, spacers connecting the vertical walls to each other, are each provided with at least one part of the same pivoting device in the form of a male element and a female element, in such a way that the assembly of two blocks between them precisely makes it possible to produce such a pivoting device and allows thus the rotation, relative to each other, of two juxtaposed blocks, so as to make changes of direction between them.

Conformément à l'invention, les blocs sont pourvus chacun d'au moins une partie d'un même disposi­tif de pivotement 12 sous la forme d'un élément mâle 14 et d'un élément femelle 16, de telle manière que l'as­semblage de deux blocs entre eux permette précisément de réaliser un tel dispositif de pivotement 12 et autorise ainsi la rotation, l'un par rapport à l'autre, de deux blocs juxtaposés, de façon à réaliser des changements de direction entre eux.According to the invention, the blocks are each provided with at least part of the same pivoting device 12 in the form of a male element 14 and of a female element 16, so that the assembly of two blocks between them precisely makes it possible to produce such a pivoting device 12 and thus allows the rotation, relative to one another, of two juxtaposed blocks , so as to make changes in direction between them.

Ces blocs sont, en général, réalisés en polys­tyrène expansé, de masse volumique apparente comprise entre 28 et 30 kg/m³.These blocks are, in general, made of expanded polystyrene, with an apparent density of between 28 and 30 kg / m³.

Un premier type de blocs comporte sur la sur­face supérieure 13 d'une portion abaissée par rapport à la tranche supérieure 5 de chaque paroi verticale 1, l'élément mâle 14 d'un dispositif de pivotement 12 qui s'étend sur toute la largeur desdits blocs (figures 1 et 2).A first type of block comprises on the upper surface 13 of a lowered portion relative to the upper edge 5 of each vertical wall 1, the male element 14 of a pivoting device 12 which extends over the entire width of said blocks blocks (Figures 1 and 2).

Selon une caractéristique de l'invention, la tranche inférieure 5′ de chaque paroi verticale 1 est pourvue, en outre, d'un élément femelle 16, permettant l'assemblage entre eux de deux blocs superposés.According to a characteristic of the invention, the lower edge 5 ′ of each vertical wall 1 is further provided with a female element 16, allowing the assembly of two superimposed blocks.

Un second type de blocs comporte sur la surfa­ce inférieure 15 d'une portion surélevée par rapport à la tranche inférieure 5′ de chaque paroi verticale 1, l'élément femelle 16 d'un dispositif de pivotement 12 qui s'étend sur toute la largeur desdits blocs (figures 3 et 4).A second type of block comprises on the lower surface 15 of a portion raised relative to the lower edge 5 ′ of each vertical wall 1, the female element 16 of a pivoting device 12 which extends over the entire width said blocks (Figures 3 and 4).

Selon une autre caractéristique de l'inven­tion, la tranche supérieure 5 de chaque paroi verticale 1 est pourvue, en outre, d'un élément male 14, permet­tant l'assemblage entre eux de deux blocs superposés.According to another characteristic of the invention, the upper edge 5 of each vertical wall 1 is further provided with a male element 14, allowing the assembly of two superimposed blocks.

Les surfaces supérieure 13 et inférieure 15 se trouvent avantageusement situées à mi-hauteur par rap­port à la hauteur totale d'un bloc.The upper 13 and lower 15 surfaces are advantageously located at mid-height relative to the total height of a block.

Comme le montrent les figures 1 à 4, chaque élément mâle 14 est sous la forme d'un anneau continu ou discontinu, et chaque élément femelle 16 est sous la forme d'une rainure continue ou discontinue, les extré­ mités des blocs étant, ainsi, arrondies.As shown in Figures 1 to 4, each male element 14 is in the form of a continuous or discontinuous ring, and each female element 16 is in the form of a continuous or discontinuous groove, the ends moths of the blocks being, thus, rounded.

Chaque anneau 14 peut être pourvu d'au moins un orifice 7 permettant à l'air de s'échapper lors de l'emboîtement des blocs entre eux.Each ring 14 can be provided with at least one orifice 7 allowing the air to escape during the interlocking of the blocks with one another.

Le premier type de blocs correspond, par con­séquent, à un bloc d'extrémité droite et le second type de blocs à un bloc d'extrémité gauche. Lorsque, par ex­emple, un changement de direction relativement brusque est souhaité, le bloc d'extrémité droite sera disposé à la suite des blocs classiques constituant le mur recti­ligne. Puis, le bloc d'extrémité gauche sera emboîté dans le bloc d'extrémité droite, cette opération s'ef­fectuant par simple emboîtement de l'anneau 14 dans la rainure 16, l'anneau 14 pouvant très facilement coulis­ser dans la rainure 16 selon l'angle désiré. Par ail­leurs, la forme circulaire de l'anneau 14, d'une part, et de la rainure 16, d'autre part, évite tout angle vif dans le mur lors d'un tel changement de direction, la forme elle-même de l'extrémité du bloc au niveau de l'anneau 14 et de la rainure 16 étant arrondie.The first type of block therefore corresponds to a right end block and the second type of block to a left end block. When, for example, a relatively sudden change of direction is desired, the right end block will be arranged following the conventional blocks constituting the straight wall. Then, the left end block will be fitted into the right end block, this operation being carried out by simple fitting of the ring 14 in the groove 16, the ring 14 being able very easily to slide in the groove 16 according to the 'desired angle. Furthermore, the circular shape of the ring 14, on the one hand, and of the groove 16, on the other hand, avoids any sharp angle in the wall during such a change of direction, the shape itself of the end of the block at the level of the ring 14 and of the groove 16 being rounded.

Bien entendu, on pourra aussi prévoir que l'anneau 14 et la rainure 15 sont discontinus. Ainsi, l'anneau 14 ne coulissera pas dans la rainure 16 mais s'y emboîtera définissant alors un certain nombre de changements de direction possible prédéterminé.Of course, it can also be provided that the ring 14 and the groove 15 are discontinuous. Thus, the ring 14 will not slide in the groove 16 but will fit therein then defining a certain number of possible predetermined direction changes.

Un troisième type de blocs comporte, sur la surface supérieure 13 d'une portion abaissée par rapport à la tranche supérieure 5 de chaque paroi verticale 1, un élément mâle 14 d'un dispositif de pivotement 12 qui s'étend sur toute la largeur dudit bloc, et sur la sur­face inférieure 15 d'une portion surélevée par rapport à la tranche inférieure 5′ de chaque paroi verticale 1, un élément femelle 16 d'un dispositif de pivotement 12 qui s'étend sur toute la largeur desdits blocs (figures 5 à 7).A third type of block comprises, on the upper surface 13 of a lowered portion relative to the upper edge 5 of each vertical wall 1, a male element 14 of a pivoting device 12 which extends over the entire width of said block, and on the lower surface 15 of a portion raised relative to the lower edge 5 ′ of each vertical wall 1, a female element 16 of a pivoting device 12 which extends over the entire width of said blocks (figures 5 to 7).

Ces blocs correspondant à ce troisième type servent de blocs intermédiaires lors d'un changement de direction dans le mur devant être moins brusque (par ex­emple un arrondi dans le mur). Ce troisième type de bloc sera alors disposé entre un bloc d'extrémité droite et un bloc d'extrémité gauche, le nombre de blocs de ce troisième type à insérer dépendant de l'arrondi dans le mur souhaité. Il va de soi que plus on insérera de blocs intermédiaires, moins le changement de direction dans le mur sera brusque et moins l'arrondi dans le mur sera prononcé.These blocks corresponding to this third type serve as intermediate blocks during a change of direction in the wall which must be less abrupt (for example a rounding in the wall). This third type of block will then be placed between a right end block and a left end block, the number of blocks of this third type to be inserted depends on the rounding in the desired wall. It goes without saying that the more intermediate blocks are inserted, the less abrupt the change of direction in the wall and the less pronounced the rounding in the wall.

Comme le montrent les figures 1 à 7, sur ces trois types de blocs, la tranche inférieure 5′ peut être pourvue d'un élément femelle 16 et la tranche supérieure 5 peut être pourvue d'un élément mâle 14, l'emboîtement d'un tel élément mâle 14 dans un élément femelle 16 per­mettant également l'assemblage de deux blocs superposés. Les parties d'extrémité arrondies des blocs empilés les uns sur les autres formeront ainsi un cylindre vertical creux dans lequel sera coulé le béton, formant ainsi en quelque sorte un pilier.As shown in FIGS. 1 to 7, on these three types of blocks, the lower edge 5 ′ can be provided with a female element 16 and the upper edge 5 can be provided with a male element 14, the fitting of such a male element 14 in a female element 16 also allowing the assembly of two superimposed blocks. The rounded end portions of the blocks stacked on top of each other will thus form a hollow vertical cylinder into which the concrete will be poured, thus forming a sort of pillar.

L'avantage de ces trois types permettant des changements de direction réside principalement dans le fait que l'anneau 14 et la rainure 16 sont disposés sur toute la largeur du bloc, ce qui a pour conséquence que tout élément additionnel devient superflu, les change­ments d'angles pouvant s'opérer directement avec les blocs eux-mêmes, sans pour autant qu'il en résulte des angles vifs, et tous les degrés de courbure désirés pou­vant être obtenus par simple pivotement d'un bloc par rapport à un autre, en faisant simplement coulisser l'anneau 14 dans la rainure 16. Il est à noter que les blocs peuvent être très facilement manipulés, même déjà emboîtés les uns dans les autres, avant la coulée du bé­ton qui s'effectue normalement par groupe de dix blocs, grâce à une pompe à béton sous une pression d'environ quatre bars, les blocs résistant à l'éclatement jusqu'à au moins six bars.The advantage of these three types allowing changes of direction lies mainly in the fact that the ring 14 and the groove 16 are arranged over the entire width of the block, which has the consequence that any additional element becomes superfluous, the changes d angles which can take place directly with the blocks themselves, without however resulting in sharp angles, and all the desired degrees of curvature which can be obtained by simple pivoting of one block relative to another, in simply sliding the ring 14 in the groove 16. It should be noted that the blocks can be very easily manipulated, even already nested one inside the other, before the concrete is poured which normally takes place in groups of ten blocks, with a concrete pump at a pressure of around four bars, the bursting blocks up to at least six bars.

Bien entendu, on pourra également prévoir que les éléments 14 et 16 du dispositif de pivotement 12 sont partiellement ou totalement creux, de manière à ce que, lors de la coulée, le béton exerce une pression sur l'anneau 14, entraînant ainsi un effet de blocage.Of course, it is also possible to provide that the elements 14 and 16 of the pivoting device 12 are partially or completely hollow, so that, during casting, the concrete exerts pressure on the ring 14, thus causing an effect blocking.

Selon une variante de réalisation de l'inven­tion, les blocs sont pourvus chacun, en outre, d'élé­ments d'assemblage 3 sous la forme chacun, d'une part, de deux éléments mâles dont l'un 9 est disposé sur la tranche supérieure 5 et l'autre 8 sur la tranche infé­rieure 5′ de chaque paroi verticale 1, et, d'autre part, de deux éléments femelles dont l'un 4 est disposé sur la tranche supérieure 5 et l'autre 6 sur la tranche infé­rieure 5′ de chaque paroi verticale 1, de manière à per­mettre l'emboîtement et le blocage entre eux des blocs superposés et juxtaposés, réalisant ainsi un blocage à double effet.According to an alternative embodiment of the invention, the blocks are each provided, in addition, with connecting elements 3 in the form each, on the one hand, of two male elements, one of which 9 is disposed on the edge upper 5 and the other 8 on the lower edge 5 ′ of each vertical wall 1, and, on the other hand, two female elements, one of which 4 is disposed on the upper edge 5 and the other 6 on the edge lower 5 ′ of each vertical wall 1, so as to allow the interlocking and blocking between them of the superimposed and juxtaposed blocks, thus achieving a double effect blocking.

Selon une caractéristique de l'invention, l'élément mâle disposé sur la tranche supérieure 5 est sous la forme d'un anneau 9 déterminant dans sa partie centrale un orifice cylindrique 4 qui correspond à l'élément femelle, également disposé sur la tranche su­périeure 5, l'élément femelle disposé sur la tranche in­férieure 5′ étant sous la forme d'une rainure 6 détermi­nant dans sa partie centrale un ergot 8 qui correspond à l'élément mâle également disposé sur la tranche infé­rieure 5′, ledit ergot 8 s'emboîtant dans l'orifice 4 et l'anneau 9 s'emboîtant dans la rainure 6.According to a characteristic of the invention, the male element disposed on the upper edge 5 is in the form of a ring 9 determining in its central part a cylindrical orifice 4 which corresponds to the female element, also disposed on the upper edge 5, the female element disposed on the lower edge 5 ′ being in the form of a groove 6 determining in its central part a lug 8 which corresponds to the male element also disposed on the lower edge 5 ′, said lug 8 s 'fitting into the orifice 4 and the ring 9 fitting into the groove 6.

Selon une autre caractéristique de l'inven­tion, l'ergot 8 présente une section conique, la dimen­sion de sa base étant légèrement plus grande que celle de sa partie supérieure qui correspond strictement au diamètre interne de l'anneau 9, de telle façon que l'ergot 8 s'emboîte dans l'orifice 4 formé par l'anneau 9 par force, tout comme l'anneau 9 dans la rainure 6 dont la dimension de la base, du fait de la connicité de l'ergot 8, est légèrement plus petite que l'épaisseur de l'anneau 9, entraînant ainsi un premier effet de blocage lors de l'emboîtement desdits blocs.According to another characteristic of the invention, the lug 8 has a conical section, the dimension of its base being slightly larger than that of its upper part which strictly corresponds to the internal diameter of the ring 9, so that the lug 8 fits into hole 4 formed by the ring 9 by force, just like the ring 9 in the groove 6, the dimension of the base, due to the connotation of the lug 8, is slightly smaller than the thickness of the ring 9, thus causing a first blocking effect during the nesting of said blocks.

Conformément à une variante de réalisation, cet ergot conique 8 sera pourvu sur toute sa hauteur d'une fente 10 permettant à l'air de s'échapper lors de l'emboîtement des blocs entre eux (voir figure 10). Bien entendu, il est aussi possible que ce soit l'anneau 9 qui est pourvu, sur toute la hauteur de sa paroi inter­ne, d'une fente 10.According to an alternative embodiment, this conical lug 8 will be provided over its entire height with a slot 10 allowing air to escape during the interlocking of the blocks between them (see FIG. 10). Of course, it is also possible that it is the ring 9 which is provided, over the entire height of its internal wall, with a slot 10.

Comme on peut le voir sur la figure 10, la rainure 6 présente une ouverture 11 située sur la face interne de la tranche inférieure 5′ de chaque paroi ver­ticale 1, qui permet au béton, lors de la coulée, d'exercer une pression contre une portion de l'anneau 9 dans lequel est emboîté l'ergot 8, la pression ainsi ex­ercée sur les éléments d'assemblage 3 permettant le se­cond effet de blocage lors de l'emboîtement desdits blocs. En effet, cette pression est suffisamment élevée pour permettre un tel effet de blocage, de l'ordre de 1,33 Newton/cm².As can be seen in Figure 10, the groove 6 has an opening 11 located on the internal face of the lower edge 5 ′ of each vertical wall 1, which allows the concrete, during casting, to exert pressure against a portion of the ring 9 in which the lug 8 is fitted, the pressure thus exerted on the assembly elements 3 allowing the second blocking effect during the fitting of said blocks. Indeed, this pressure is high enough to allow such a blocking effect, of the order of 1.33 Newton / cm².

L'ergot 8 pourra présenter avantageusement, dans un exemple de réalisation donné à titre non limita­tif, une hauteur de 15 mm, un diamètre supérieur de 20 mm, un diamètre inférieur de 21 mm, une fente 10 de 1 mm de profondeur et de 2 mm de large, la rainure 6 un diamètre extérieur de 40 mm, son diamètre intérieur étant déterminé par l'ergot 8, et une ouverture 11 de forme rectangulaire de 20 mm de large et 15 mm de haut, l'anneau 9 présentant avantageusement un diamètre exté­rieur de 40 mm et un diamètre intérieur de 20 mm, iden­tique au diamètre de la partie supérieure de l'ergot 8.The lug 8 may advantageously have, in an exemplary embodiment given without limitation, a height of 15 mm, a greater diameter of 20 mm, a smaller diameter of 21 mm, a slot 10 of 1 mm in depth and 2 mm wide, the groove 6 an outer diameter of 40 mm, its inner diameter being determined by the lug 8, and an opening 11 of rectangular shape 20 mm wide and 15 mm high, the ring 9 advantageously having a outer diameter of 40 mm and an inner diameter of 20 mm, identical to the diameter of the upper part of lug 8.

Les anneaux 9 sont donc disposés sur la tran­che supérieure 5 des parois verticales 1 des blocs côte à côte, occupant pratiquement toute la largeur de la tranche supérieure 5, lesdits anneaux 9 étant espacés entre eux d'une distance d'environ 10 mm. Il en va de même pour les rainures 6 qui sont disposées sur la tran­che inférieure 5′ des parois verticales 1.The rings 9 are therefore arranged on the upper edge 5 of the vertical walls 1 of the side blocks side by side, occupying practically the entire width of the upper edge 5, said rings 9 being spaced apart from each other by a distance of approximately 10 mm. The same goes for the grooves 6 which are arranged on the lower edge 5 ′ of the vertical walls 1.

L'assemblage parfait des blocs entre eux, sans aucun risque de désolidarisation d'un bloc par rapport à un autre, est, par conséquent, obtenu, d'une part, grâce à la conicité de l'ergot 8 et, d'autre part, grâce à l'ouverture 11 permettant au béton d'exercer une pres­sion sur les éléments d'assemblage 3. De plus, la tran­che supérieure 5 présente un élément mâle 9 et un élé­ment femelle 4 et la tranche inférieure 5′ également un élément mâle 8 et un élément femelle 6, ce qui entraîne, lors de l'assemblage des blocs entre eux, un double em­boîtement, d'une part, de l'élément mâle 9 dans l'élé­ment femelle 6 et, d'autre part de l'élément mâle 8 dans l'élément femelle 4. Ce double emboîtement augmente bien entendu la sécurité de l'assemblage de deux blocs entre eux.The perfect assembly of the blocks together, without any risk of separation of one block with respect to another, is therefore obtained, on the one hand, thanks to the conicity of the lug 8 and, on the other hand part, thanks to the opening 11 allowing the concrete to exert pressure on the assembly elements 3. In addition, the upper edge 5 has a male element 9 and a female element 4 and the lower edge 5 ′ also an element male 8 and a female element 6, which causes, when assembling the blocks together, a double interlocking, on the one hand, of the male element 9 in the female element 6 and, on the other hand of the male element 8 in the female element 4. This double interlocking of course increases the security of assembling two blocks together.

Enfin, les blocs sont assemblés côte à côte, leurs parois latérales étant pourvues d'éléments d'as­semblage sous la forme d'un élément mâle 18 et d'un élé­ment femelle 19.Finally, the blocks are assembled side by side, their side walls being provided with assembly elements in the form of a male element 18 and a female element 19.

Grâce à l'invention, il est donc possible de réaliser, par exemple, des murs de n'importe quel profil avec, au total, quatre types de blocs différents, l'un servant à réaliser les parois rectilignes du mur et les trois autres servant à réaliser les changements de di­rection souhaités dans ce mur.Thanks to the invention, it is therefore possible to produce, for example, walls of any profile with, in total, four different types of blocks, one serving to produce the rectilinear walls of the wall and the other three used to make the desired direction changes in this wall.

Il va de soi que les blocs conformes à l'in­vention peuvent être destinés à d'autres applications que celles du coffrage d'un mur et même dans d'autres domaines que celui du bâtiment. A titre d'exemple, bien entendu non limitatif, ces blocs pourront être miniatu­risés et être réalisés en matière synthétique ou autre, de manière à servir d'éléments de construction pour des jeux d'enfant, le dispositif de pivotement 12 permet­tant, là aussi, tous les changements de direction sou­haités.It goes without saying that the blocks according to the invention can be intended for other applications than those of the formwork of a wall and even in other fields than that of the building. By way of example, of course not limiting, these blocks can be miniaturized and be made of synthetic or other material, so as to serve as construction elements for children's games, the pivoting device 12 again allowing all the desired changes of direction.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins an­nexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
