Definitions
- the author of the present invention has already imagined and proposed metal frameworks for construction panels, which comprise, on the one hand, two parallel trellis layers each formed from a series of warp threads and a series of threads weft, welded together and each forming a network of meshes, and, on the other hand, bracing members of these two plies, oblique to these plies and extending in a general direction parallel to one series of threads of the two layers.
- these bracing members are each formed of a continuous wire bent in a zig-zag and whose successive waves are of alternating obliquity with respect to these layers and are welded by their vertices alternately to these two layers.

- the embodiment according to fig. 1 to 3 comprises two flat plies A6, B6 formed of metallic wires of parallel chains 27a, 27b, and of metallic weft wires 28a, 28b, each of these plies forming a network of square or rectangular meshes. These two plies are offset with respect to each other, in the warp direction and in the weft direction (fig. 4) by the value of half a mesh in the example shown. This discrepancy, the reason for which will be indicated below, could be different.
- bracing members 31, 32, 33, 34 each formed by a metal wire bent in a zig-zag as shown in FIG. 1. These threads each extend in the general direction of the chain of layers A6, B6.

Abstract
Description
L'auteur de la présente invention a déjà imaginé et proposé des ossatures métalliques pour panneaux de construction, qui comprennent, d'une part, deux nappes de treillis parallèles formées chacune d'une série de fils de chaîne et d'une série de fils de trame, soudés entre eux et formant chacune un réseau de mailles, et, d'autre part, des organes d'entretoisement de ces deux nappes, obliques par rapport à ces nappes et s'étendant selon une direction générale parallèle à l'une des séries de fils des deux nappes. Dans cette proposition antérieure, ces organes d'entretoisement sont formés chacun d'un fil continu plié en zig-zag et dont les ondes successives sont d'obliquité alternée par rapport à ces nappes et sont soudées par leurs sommets alternativement à ces deux nappes.The author of the present invention has already imagined and proposed metal frameworks for construction panels, which comprise, on the one hand, two parallel trellis layers each formed from a series of warp threads and a series of threads weft, welded together and each forming a network of meshes, and, on the other hand, bracing members of these two plies, oblique to these plies and extending in a general direction parallel to one series of threads of the two layers. In this previous proposal, these bracing members are each formed of a continuous wire bent in a zig-zag and whose successive waves are of alternating obliquity with respect to these layers and are welded by their vertices alternately to these two layers.
A l'usage on a remarqué qu'il était assez difficile de positionner exactement sur les sommets des ondulations les fils des deux nappes que l'on doit souder sur ces sommets. Ainsi, par exemple, si ce sont les fils de trame des deux nappes qui doivent être soudés sur les sommets des ondulations des organes d'entretoisement, et si l'on veut souder simultanément ces fils de trame sur ces sommets et, simultanément, les fils de chaîne sur les fils de trame, pour former des noeuds des réseaux au droit de ces sommets, on se heurte aux difficultés suivantes, qui rendent difficile une fabrication automatisée : D'abord, comme déjà dit, il est difficile d'amener tous les fils dε trame simultanément en contact avec le sommet des ondulations. Ensuite, au moment où l'on veut souder électriquement et simultanément, d'une part, les fils de chaîne sur les fils de trame (pour former les noeuds des réseaux) et, d'autre part, les fils de trame sur les sommets des ondulations des organes d'entretoisement, on doit nécessairement exercer une pression avec l'une des électrodes, sur les fils de trame et de chaîne, à l'endroit où ils se croisent en regard du sommet des ondulations. Cette pression tend à faire glisser les fils de trame sur le sommet des ondulations et à les écarter de ces sommets, d'où mauvaise qualité de l'ossature ainsi obtenue.In use, we have noticed that it was quite difficult to position the wires of the two sheets exactly on the tops of the corrugations, which must be welded on these tops. Thus, for example, if it is the weft threads of the two plies which must be welded to the tops of the corrugations of the bracing members, and if we want to weld these weft threads simultaneously on these tops and, simultaneously, warp threads on the weft threads, to form nodes of the networks at the right of these summits, we encounter the following difficulties, which make automated manufacturing difficult: First, as already said, it is difficult to bring all the weft yarns simultaneously in contact with the top of the corrugations. Then, when we want to weld electrically and simultaneously, on the one hand, the warp threads on the weft threads (to form the nodes of the networks) and, on the other hand, the weft threads on the vertices ripples of the bracing members, we must necessarily exert pressure with one of the electrodes, on the weft and warp threads, at the place where they cross opposite the top of the corrugations. This pressure tends to slide the weft threads on the top of the corrugations and to move them away from these tops, hence the poor quality of the framework thus obtained.
La présente invention vise à remédier à cet inconvénient sérieux et elle a pour objet une ossature métallique conforme à la revendication 1.The present invention aims to remedy this serious drawback and it relates to a metal frame according to claim 1.
Le dessin annexé représente, à titre d'exemple, une forme d'exécution de l'ossature métallique selon l'invention.The accompanying drawing shows, by way of example, an embodiment of the metal frame according to the invention.
- Fig. 1 en est une vue en perspective.Fig. 1 is a perspective view thereof.
- Fig. 2 est une coupe partielle selon 2-2 de fig. 1.Fig. 2 is a partial section on 2-2 of FIG. 1.
- Fig. 3 est une vue de détail de la fig. 2, mais à plus grande échelle.Fig. 3 is a detailed view of FIG. 2, but on a larger scale.
La forme d'exécution selon fig. 1 à 3 comprend deux nappes A6, B6 planes formées de fils métalliques de chaînes parallèles 27a, 27b, et de fils métalliques de trame 28a, 28b, chacune de ces nappes formant un réseau de mailles carrées ou rectangulaires. Ces deux nappes sont décalées l'une par rapport à l'autre, dans le sens de la chaîne et dans le sens de la trame (fig. 4) de la valeur d'une demi-maille dans l'exemple représenté. Ce décalage, dont la raison sera indiquée plus loin, pourrait être différent.The embodiment according to fig. 1 to 3 comprises two flat plies A6, B6 formed of metallic wires of
Entre les deux nappes A6, B6, sont disposés des organes d'entretoisement 31, 32, 33, 34 formés chacun par un fil métallique plié en zig-zag comme le montre la fig. 1. Ces fils s'étendent chacun selon la direction générale de la chaîne des nappes A6, B6.Between the two plies A6, B6, are arranged bracing
Chaque coude inférieur 31a, 32a, 33a, etc. de ces fils d'entretoisement coïncide et fait contact avec un fil de trame 28a de la nappe A6; à l'endroit d'un noeud de cette nappe. A cet endroit un fil d'entretoisement 31, 32, 33 et deux fils 27a et 28a de la nappe A6 sont soudés ensemble, électriquement.Each
De même, chaque coude supérieur 31b, 32b, 32c etc. des fils d'entretoisement 31, 32, 33 coïncide et fait contact avec un fil de trame 28b de la nappe B6, à l'endroit d'un noeud de cette 'nappe. A cet endroit, un fil d'entretoisement 31, 32, 33.. et deux fils 27b et 28b de la nappe B6 sont soudés ensemble, électriquement.Likewise, each
On voit que les fils d'entretoisement, y compris leurs coudes, sont situés à l'intérieur des deux nappes A6, B6, ce qui facilite la fabrication.We see that the bracing wires, including their elbows, are located inside the two layers A6, B6, which facilitates manufacture.
On voit sur la fig. 1 que chaque organe d'entretoisement 31, 32, 33.. forme une succession d'ondes triangulaires inclinées alternativement d'un côté et symétriquement du côté opposé. Ainsi, sur la figure 1, les ondes triangulaires de l'organe d'entretoisement 31 qui ont leur sommet soudé sur le fil de chaîne 27b de gauche, sont inclinées vers la gauche, tandis que les ondes qui leur font suite et qui ont leur sommet soudé sur le deuxième fil de chaîne à partir de la gauche, sont inclinés vers la droite. La fig. 2 montre clairement cette disposition.We see in fig. 1 that each
Pour faciliter le positionnement exact des fils de trame sur les sommets des ondes triangulaires des organes d'entretoisement, et le maintien en place de ces fils à cet endroit pendant le soudage, il est prévu (fig. 2 et 3) au sommet de chacune de ces ondes une partie concave 35 formant un creux dans lequel passe et est soudé un fil de trame 28a, respectivement 28b. Ainsi, les fils de trame se positionnant exactement au sommet de chaque onde, c'est-à-dire dans le creux se trouvant à ce sommet. Et lorsque l'on vient agir avec les électrodes de soudure électrique, comme indiqué par des flèches sur la fig. 2, la pression ainsi exercée sur les fils de trame n'a pas tendance à écarter ces fils de ces sommets comme c'est le cas lorsque ces sommets sont convexes ou pointus.To facilitate the exact positioning of the weft threads on the tops of the triangular waves of the bracing members, and the holding in place of these threads at this location during welding, it is provided (fig. 2 and 3) at the top of each of these waves a
Dans une variante, ce que l'on a décrit comme étant des fils de chaîne, pourrait être des fils de trame et inversement. Alors, les organes d'entretoisement s'étendraient selon une direction générale parallèle à la direction des fils de trame, tandis que dans l'exemple décrit, ils s'étendent selon une direction parallèle à celle des fils de chaine.In a variant, what has been described as warp threads, could be weft threads and vice versa. Then, the bracing members would extend in a general direction parallel to the direction of the weft threads, while in the example described, they extend in a direction parallel to that of the warp threads.
Le terme de fils employé pour désigner les différents éléments dont est formée l'ossature décrite, doit être compris dans un sens général englobant tous les fers d'armatures utilisables dans la technique du béton armé.The term "son" used to designate the various elements from which the described framework is formed, must be understood in a general sense encompassing all reinforcing bars usable in the reinforced concrete technique.
De même, le terme triangulaire utilisé pour indiquer la forme des ondes successives du zig-zag formé par chaque organe d'entretoisement, doit être compris d'une manière large et pas dans le sens précis, étroit, de la géométrie.Likewise, the triangular term used to indicate the shape of the successive waves of the zig-zag formed by each bracing member, must be understood in a broad manner and not in the precise, narrow sense of geometry.
