Abstract

The prefabricated wall section is constructed from two concrete walls, separated by a space containing insulating material. The reinforcing assembly has horizontal prestressed rods (1), extending over the entire wall length and vertical rods (2), interconnected by transverse wires (3). The wire ends are bent to retain the horizontal, prestressed rods. The bent ends of the transverse wires consist of refined steel, and in addition act as fasteners for a metal reinforcing grid for one side of the wall.

Description

La présente invention concerne un nouveau type d'armature métallique utilisable dans les parois, cloisons, murs ou tous autres éléments, en combinaison éventuellement avec un treillis, en vue du renforcement du matériau utilisé pour fabriquer ces éléments, et plus spécialement des différents bétons. The present invention relates to a new type of metallic reinforcement usable in walls, partitions, walls or any other element, possibly in combination with a trellis, with a view to reinforcing the material used to manufacture these elements, and more especially different concretes.

Cette armature se compose, d'une part d'un ensemble de barres horizontales tendues, s'étendant sur toute la longueur de chaque face de l'élément, d'autre part d'un ensemble de barres verticales réunies par des barres transversales repliées à leurs extrémités et dont au moins lesdites extrémités pliées sont en inox, pour recevoir les barres tendues et éventuellement des treillis de renforcement des parois d'un mur épais. La combinaison de ces deux ensembles constitue une cage de construction simple, solide et pouvant être fabriquée à la demande en longueur et en épaisseur. This frame consists, on the one hand of a set of horizontal tensioned bars, extending over the entire length of each face of the element, on the other hand of a set of vertical bars joined by folded transverse bars at their ends and at least said folded ends of which are made of stainless steel, for receiving the tensioned bars and possibly reinforcing trellises for the walls of a thick wall. The combination of these two sets constitutes a simple, solid construction cage which can be produced on demand in length and thickness.

Le dessin annexé représente un exemple de réalisation de cette armature,
- la figure 1 étant une vue perspective schématique,
- la figure 2 étant une vue d'extrémité, et
- la figure 3 étant un agrandissement partiel de la figure 2.The appended drawing represents an exemplary embodiment of this frame,
FIG. 1 being a schematic perspective view,
FIG. 2 being an end view, and
- Figure 3 is a partial enlargement of Figure 2.

Sur ce dessin, on voit que l'armature selon l'invention forme une cage constituée par des barres tendues ou précontraintes 1-1' réparties horizontalement sur toute la longueur du mur à armer. In this drawing, it can be seen that the frame according to the invention forms a cage constituted by tensioned or prestressed bars 1-1 'distributed horizontally over the entire length of the wall to be reinforced.

Ces barres 1-1' sont réunies par des barres verticales 2 elles-mêmes reliées par des entretoises horizontales 3. Ces entretoises sont repliées à leurs extrémités 4 correspondant aux barres I (voir figures 2 et 3), de manière à recevoir ces barres et éventuellement à fixer un treillis de renforcement 5 de l'une des faces du mur. These bars 1-1 ′ are joined by vertical bars 2 themselves connected by horizontal spacers 3. These spacers are folded at their ends 4 corresponding to the bars I (see FIGS. 2 and 3), so as to receive these bars and possibly to fix a reinforcement mesh 5 of one of the faces of the wall.

Des boucles de levage usuelles 6 sont soudées de loin en loin sur les barres verticales 2. Usual lifting loops 6 are welded from time to time on the vertical bars 2.

Ce nouveau type d'armature présente sur le plan technique une série d'avantages intéressants
En premier lieu la paroi intérieure peut reposer directement sur le fond du moule 7, les parties repliées 4 étant en inox. Cela permet d'éviter l'emploi des cales en plastiques nécessaires jusqu'ici.This new type of reinforcement has a series of interesting technical advantages
Firstly, the inner wall can rest directly on the bottom of the mold 7, the folded parts 4 being made of stainless steel. This avoids the use of plastic wedges necessary so far.

D'autre part les plis 4 peuvent recevoir les huit barres tendues sans risque de déplacement, et éventuellement les treillis, formant une attache sérieuse des parois. On the other hand the folds 4 can receive the eight tensioned bars without risk of displacement, and possibly the trellis, forming a serious attachment to the walls.

Enfin les mêmes fils pliés en inox 3 guident à leur partie supérieure les barres 1 ou le treillis 5, ce qui constitue une attache très sérieuse de l'armature à la paroi externe du mur.  Finally, the same folded stainless steel wires 3 guide the bars 1 or the trellis 5 at their upper part, which constitutes a very serious attachment of the frame to the external wall of the wall.
