Abstract

In the formwork element used for construction of concrete sheathing walls, two hard foam panels are connected by space retainers with their edges moulded into the panels. The space retainers (1), of height corresponding to that of the formwork element, are made in ladder form, the side bars (2) being connected to reinforcing grids for the hard foam panels (7). The rung-type pieces of the spacers can be in the form of raised battens (3). The horizontally aligned bars (6) of the reinforcing grids can be hung in hooks (5) on the spacers. The spacers' side bars can have an inside edge (10) protruding out of the panels.

Description

SCHALUNGSELEMENTFORMWORK ELEMENT

Die Erfindung bezieht sich auf ein Schalwngselement zur Herstellung von Mantelbefonsänden, bei dem zwei Hartschaumplatten durch mit ihren Rändern in die Platten eingeschäumte Distanzhalter verbunden sind.The invention relates to a formwork element for manufacture of Mantelbefonsängen, in which two rigid foam panels with their edges in the panels are connected to foamed spacers.

Eine bekannte derartige Einrichtung ist in OE-PS 322.804 beschrieben. Die Distanzhalter bestehen dabei aus einzelnen übereinander angeordneten Stegen aus Asbestzement' deren Verankerung in den aus Styropor od. dgl. bestehenden Platten problematisch ist. Außerdem komt-es beim Ausfüllen des Schalungselementes mit Beton leicht zu Verformungen der nicht bewehrten Hartschaumplatten.A known device of this type is described in OE-PS 322804. The spacers consist of individual webs arranged one above the other from asbestos cement 'their anchoring in the styrofoam or the like existing plates is problematic. In addition, it comes when the formwork element is filled with concrete easy to deformation of the non-reinforced rigid foam panels.

Aus OE-PS 289.357 ist es allerdings auch schon bekannt geworden, zwei Betonplatten, die eine gitter£Qrmige Bewehrun und zudem eine Schaumstoffauflage aufweisen, durch Distanzhalter zu einem Schalungselement zu verbinden. Die Distanzhalter werden hier nachträglich an Ösen angebracht, die über die Innenseiten der beiden Platten vorstehen. Besonders bei geringem-Abstand der beiden Platten ist die Montage derartiger Distanzhalter keineswegs einfach und sie sind auch nicht geeignet, dem gesamten Schalungselement hinreichende Stabilität zu verleihen; Ziel der Erfindung ist es dem gegenüber, ein Schalungselement zu schaffen,-das sich durch hohe Stabilität auszeichnet und somit leicht transportiert und für die Ausfüllung mit Beton vorbereitet werden kann. Erfindungsgemäß wird dies dadurch erreicht, daß die Distanzhalter, deren Höhe jener des Schalungselementes entspricht, leiterförmig ausgebildet sind,-wobei die Holme mit Bewehrungsgittern für die Hartschaumplatten verbunden sind.However, it has already become known from OE-PS 289.357, two Concrete slabs with a lattice-shaped reinforcement and a foam pad have to be connected by spacers to form a formwork element. The spacers are subsequently attached to eyelets on the inside of the two Plates protrude. The assembly is particularly important when the distance between the two plates is small such spacers by no means simple and they are also not suitable for the to give the entire formwork element sufficient stability; Object of the invention on the other hand it is to create a formwork element, which is characterized by high stability characterized and thus easily transported and prepared for filling with concrete can be. According to the invention this is achieved in that the spacers, whose height corresponds to that of the formwork element, are ladder-shaped, -which the spars are connected with reinforcement grids for the rigid foam panels.

Der Hauptvorteil der Erfindung liegt darin, daß die'Herstellung des vorgeschlagenen Schalungselementes sehr einfach ist.The main advantage of the invention is that the manufacture of the proposed formwork element is very simple.

Sobald in die Distanzhalter, welche hiezu vorzugsweise mit Haken versehen sind, die Bewehrungsgitter eingehängt sind, ist bereits ein stabiles Gerüst gegeben, das leicht umschaunt werden kann und dadurch noch an Festigkeit gewinnt.Once in the spacers, which are preferably provided with hooks for this purpose the reinforcement grids are attached, is already a stable one A framework is given that can easily be covered with a shade and is therefore even more firm wins.

Weitere Einzelheiten der Erfindung werden anschließend anhand der Zeichnung dargelegt. Darin stellt Fig. 1 einen Vertikalschnitt nach der Ebene 1-1 in Fig. 2, Fig. 2 einen Horizontalschnitt nach der Ebene II- II in Fig. 1 dar.Further details of the invention will then be described with reference to FIG Drawing outlined. 1 shows a vertical section along the plane 1-1 in Fig. 2, Fig. 2 is a horizontal section along the plane II-II in Fig. 1.

t Das dargestellte Schalungselement besteht im wesentlichen aus zwei Hartschaumplatten 7, die durch Distanzhalter 1 zu einem kastenartigen Gebilde verbunden sind. Verstärkt sind die Hartschaumplatten 7 durch aus Kunststoff bestehende Bewehrungsgitter, deren vertikale und horizontale Gitterstäbe mit 6' bzw. 6 bezeichnet sind. Das dargestellte Schalungselement bildet eine stabile Einheit, was sich aus der Art der Herstellung erklärt: Zunächst werden die Distanzhalter 1 aufgestellt und dann in die an diesen vorgesehenen Haken 5 horizontalen Stabe 6 der Bewehrungsgitter eingehängt. HierauS werden die Hartschaumplatten 7 um das Gitter und den äußeren Rand der Distanzhalter 1 geschäumt, wodurch nicht nur automatisch eine Bewehrung der Hartschaumplatten 7, sondern auch eine feste Verbindung zwischen Distanzhaltern 1 und Bewehrungsgittern entsteht. t The shuttering element shown consists essentially of two Rigid foam panels 7, which are connected by spacers 1 to form a box-like structure are. The rigid foam panels 7 are reinforced by reinforcement grids made of plastic, the vertical and horizontal bars of which are denoted by 6 'and 6, respectively. The depicted Formwork element forms a stable unit, which is evident from the way it is manufactured explains: First, the spacers 1 are set up and then in those on them provided hooks 5 horizontal bars 6 hooked on the reinforcement grid. Here the rigid foam panels 7 are around the grid and the outer edge of the spacer 1 foamed, which not only automatically reinforces the rigid foam panels 7, but also a fixed connection between spacers 1 and reinforcement grids arises.

Die Schäumform kann besonders einfach sein, wenn die Holme 2 der leiterartigen Distanzhalter 1 einen nicht umschäumten Innenrand 10 aufweisen, sodaß die inneren Formhälften einfach als den Raum zwischen zwei Distanzhaltern ausfüllende Kastenprofile ausgestaltet sein können. Die Außenseiten des Schalungselementes werden ohnedies durch einfache Platten geformt.The foam mold can be particularly simple if the spars 2 of the ladder-like Spacers 1 have a non-foamed inner edge 10, so that the inner Mold halves simply as box profiles filling the space between two spacers can be designed. The outsides of the formwork element are anyway formed by simple plates.

Ebenso wie die Bewehrungsgitter bestehen die Distanzhalter 1 vorzugsweise- aus einem Kunststoff, wie PVC. Um Material zu spsren, ist der Querschnitt des äußeren Sandes der Holme 2 der leiterartigen Distanzhalter 1 jeweils mit einer Verdick-urg 4 versehen, welche vor dem Aufbringen des Schaumstoffes die Last der :23ewehungs¢Titter abstützt. Zwischen den Holmen 2 verlaufen Leisten 3, die in an stich bekannter Weise hochgestellt sind, damit sie beim Einschatten des Betons ein möglichst geringes Hindernis bilden. Die Öffnungen 8 zwischen den Leiste 3 reichen ohne weiteres aus, die Kpntinuität der Betonfüllung zu sichern und erlauben auch die Einführung horizontal verlaufender Bewehrungen. Das Einbringen von vertikalen Bewehrungseisen ist beim erfindungsgemäßen Schalungselement ebenfalls in ganzen Raum zwischen den einzelnen Distanzhaltern 1 möglich.Just like the reinforcement grids, the spacers 1 are preferably made of a plastic such as PVC. To lock material, the cross section is the outer Sand the bars 2 of the ladder-like spacers 1 each with a thickening 4, which, before the foam is applied, the load of: 23ewehungs ¢ Titter supports. Between the spars 2 run strips 3, which stich in As is known, they are raised so that they are as good as possible when shading the concrete form minor obstacle. The openings 8 between the bar 3 reach easily designed to ensure the continuity of the concrete filling and also allow the introduction horizontal reinforcement. The introduction of vertical rebars is also in the entire space between the formwork element according to the invention individual spacers 1 possible.

Durch die vorgesehene Kunststoffbewehrung bereitet die Zerteilung vorgefertigter Schalungselemente keine Schwierigkeiten, sodaß diese jeweils bereits in der gewünschten Größe an die Baustelle geliefert oder auch dort noeh zugeschnitten werden können. Zur seitlichen Verbindung mehrerer Schalungselemente können mit den Schalungselementen verklebte Verbindungsstege 9 vorgesehen werden. Die Höhe der Elemente wird üblicherweise den genormten Raumhöhen entsprechen, doch ist auch eine wesentlich geringere Dimensionierung der Schalungselemente und deren Zusammenbau zu Raumwänden unter Beibehaltung der dargelegten Vorteile möglich.The planned plastic reinforcement prepares the division prefabricated formwork elements no difficulties, so that each already Delivered to the construction site in the desired size or cut to size there can be. For the lateral connection of several formwork elements, the Formwork elements glued connecting webs 9 are provided. The high of Elements will usually correspond to the standardized room heights, but there is also one significantly smaller dimensioning of the formwork elements and their assembly to room walls while maintaining the advantages outlined possible.
