Definitions

  • bracing wires are rectilinear sections which have to be put in place individually for their welding to the two plies.
  • these elements must necessarily be welded not exactly to the knots of the meshes, already formed and welded at the location of these knots, but at a certain distance from these knots, which is unfavorable both from the point of view of manufacturing. than the mechanical strength of the trellis.
  • the present invention aims to provide a frame of the type which has just been mentioned, but which is improved by eliminating the two disadvantages mentioned.
  • the present invention relates to a three-dimensional metal frame for a building panel which conforms to claim 1.
  • the invention also includes a method of manufacturing such a frame, which is according to claim 13.
  • Figs. 1 and show it three metal wires (or reinforcing bars) 1, 2, 3, preformed as will be described, arranged side by side at a certain distance from each other.
  • This wire is in a zig-zag and forms a series of elbows 4a, 4b, 4c, 4d ,, 4th ... arranged in a straight line 5a.
  • Homologous elbows of the wires 2 and 3 are arranged on two parallel straight lines 5b and 5c.
  • the portion of the wire 1 located between the elbows 4a and 4b is itself bent at 6a.
  • the section between 4b and 4c is bent at 6b
  • the section between 4c and 4d is bent at 6c
  • the section between 4d and 4e is bent at 6d.
  • the parts 4a, 6a, 4b define an oblique triangle to the right with respect to the plane of the parallel straight lines 5a, 5b, 5c.
  • the following parts 4b, 6b, 4c define a triangle of the same dimensions as the first, but oblique to the left relative to the plane of the parallel straight lines 5a, 5b, 5c.
  • the following parts 4c, 6c, 4d define a triangle identical to the first 4a, 6a, 4b.
  • the following parts, 4d, 6d, 4e define a triangle identical to the second 4b, 6b, 4c.
  • Fig. shows that the triangles, alternately oblique to the right and to the left, are inclined symmetrically with respect to the plane of the lines 5a, 5b, 5c.
  • Fig. 1 shows that the elbows 4a, 4b, .. 4th of the wire 1 and their counterparts on the wires 2 are located on straight lines 7a, 7b, ... 7th perpendicular to the lines 5a, 5b, 5c.
  • wires 1, 2, 3 To form the wires 1, 2, 3 according to fig. 1 and there, we start, for each of them, with a flat wire, bent in a zig-zag whose vertices are 6a, 6b, 6c, 6d as regards wire 1.
  • wires 1, 2, 3, We fold each of the flat layers formed by wires 1, 2, 3, around line 5a, 5b, 5c, respectively, as indicated by arrows in fig. the.
  • wires 1, 2, 3 thus preformed being placed as shown in FIG. 1, a first series of straight and parallel wires 8a, 8b, 8c, 8d, 8e are brought laterally, so that they come to be placed inside the lower elbows 4a, 4b, 4c, 4d, 4th, respectively, of wire 1 and homologous elbows of wires 2 and 3, as shown in fig. 2.
  • intermediate wires 9a, 9b, 9c, 9d are introduced, parallel to the first ones and situated in the same plane as them.
  • wires lOa, lOb, lOc, lOd similar to 8a, 8b, 8c ... are introduced, but which are placed inside the upper elbows 6a, 6b, 6c, 6d, respectively of wire 1 and homologous elbows of wires 2 and 3.
  • intermediate wires lla, llb, llc, lld are introduced, parallel to the first and located in the same plane as them.
  • the wires 8a, 8b, ... and 9a, 9b ... are intended to form, in this example, the weft son of one of the two lattices which the completed framework comprises.
  • the wires 10a, lOb ... and lla, llb ... are intended to form the weft son of the second lattice which the completed framework comprises.
  • the lower ply is placed so that the wire 12b is in contact with the elbows 4a, 4b, 4c, 4d of the wire 1 and below these elbows.
  • the wire 12c is in contact with the homologous lower elbows of the wire 2 and below these elbows.
  • the upper ply 13a, 13b ... 13e is placed so that the wire 13a is in contact with the upper left elbows 6b, 6d of the wire 1 and above them.
  • the wire 13b is placed to be in contact with the upper left elbows of the wire 2 and above them.
  • the wire 13c is placed to be in contact with the upper right elbows 6a, 6c of the wire 1 and above them.
  • the wire 13d is placed to be in contact with the upper right elbows of the wire 2 counterparts of 6a, 6c.
  • All the wires shown in fig. 3 are then electrically welded at the location of the nodes of the two trellises formed by the lower rectilinear wires and by the upper rectilinear wires, respectively.
  • nodes such as those which are for example at the intersections of wire 9a with 12a, 12b ..., or of wire 9b with 12a, 12b ..., it is only the two wires which cross which are welded one to the other.
  • nodes such as those which are, for example, at the intersections of wire 8a with 12b, 12c ... or wire 8b with 12b, 12c ..., these are three wires which are welded simultaneously together: the two cross wires and wire 1, 2 ... which is placed between them.
  • Fig. 3 therefore shows a portion of the first embodiment of the framework and we see that it is formed of a lower lattice A1 with square meshes (or rectangular), of an identical upper lattice Bl, the meshes of which are exactly opposite those of the lower ply, and of wires 1, 2, 3 ... of bracing of these two plies, the successive rectilinear portions of which are oblique to the wires forming the trellis.
  • these lattices A1, B1 the wires 12a, 12b, 12c ... and 13a, 13b, 13c ... form the chain wires, while the perpendicular wires 8a, 9a, 8b, 9b, 8c, 9c ... and lOa, lla, lOb, 11b, 10c, llc ... form the weft threads.
  • the bracing wires 1, 2, 3 .. are each arranged in a general direction parallel to the warp son.
  • Figs. 3 and 3a show that the quality of the bracing is excellent.
  • the sequence of manufacturing operations could be as follows, instead of that described. We would start by setting up the lower warp threads 12a, 12b ... 12e, then we would put the bracing threads 1, 2, 3, 4, ... on them, then we would have the weft threads 8a, 8b ... 9a, 9b ... 10a, lOb ... and 11a, 11b ..., as described, after which the upper warp threads 13a, 13b, 13c ... would be laid on the together and we would electrically weld the wires at the knots.
  • the bracing wires 1, 2, 3 could be arranged in a general direction parallel not to the warp yarns of the two layers of trellis, but parallel to the weft yarns of these plies . So, 12a, 12b, 12c ... and 13a, 13b, 13c .... would be weft threads and 8a, 8b, 8c ... 9a, 9b, 9c ... lOa, 10b, 10c ... and lla, 11b, llc ... would be warp threads.
  • the two lattices A2, B2 are offset with respect to each other by half a mesh in the direction of the frame.
  • the wire 18a passes between 15a and 17a at the place of the knot where they cross, then it passes between 14a and 16a at the place of the knot where they cross, then it passes between 15b and 17b, then between 15a and 17c, etc.
  • the neighboring wire 18b passes between 15b and 17a at the location of the knot where they cross, then between 14b and 16a, then between 15c and 17b, etc.
  • the three wires are welded together, electrically.
  • only half of the knots have a bracing wire welded to a warp thread and a weft thread.
  • the other half of the nodes is formed by crossing and welding a warp thread and a weft thread only.
  • bracing wires have a shape analogous to that of the wires 18a, 18b, 18c of FIG. 4, but however with this difference that 19a, for example, passes through knots of two warp threads of the trellis B3, spaced from each other by the width of two meshes instead of one in the case of fig . 4.
  • the embodiment according to fig. 6 to 9 comprises two flat sheets A6, B6 formed of metallic warp threads 27a, 27b, and of metallic weft threads 28a, 28b, each of these sheets 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. 9) 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. 6. These threads each extend in the general direction of the chain of layers A6, 'B6.
  • Each lower bend 31a, 32a, 33a, etc. of these bracing threads coincides and makes contact with a weft thread 28a of the ply A6, at the location of a node of this ply.
  • a spacer wire 31, 32, 33 and two wires 27a and 28a of the sheet A6 are welded together, electrically.
  • each upper bend 31b, 32b, 32c, etc. of the bracing wires 31, 32, 33 coincides and makes contact with a weft thread 28b of the ply B6, at the place of a knot of this tablecloth.
  • a bracing wire 31, 32, 33 ... and two wires 27b and 28b of the sheet B6 are welded together, electrically.
  • bracing wires including their elbows, are located inside the two plies A6, B6, which facilitates manufacture.
  • the bracing wires 31, 32, 33 ... previously bent as shown in FIG. 6, are arranged in the relative position which they must occupy in the completed framework, and a mattress (FIG. 10) of injected material 35, for example polyurethane, is formed, coating and immobilizing these wires 31, 32, 33. .. in a block with protruding elbows 32a, 32b of these bracing members.
  • injected material 35 for example polyurethane
  • the wires of the layers A6, B6 are brought onto this mattress, as has been said, so that a node of each network coincides with an elbow 32a, 32b, and the three wires crossing each other electrically are welded, by means of electrodes acting as indicated by arrows in fig. 10. It can be seen that the passages 36 each allow the passage of one of the welding electrodes.
  • the welding electrodes Due to the double offset indicated by the networks of the plies A6, B6 (fig. 9), the welding electrodes have free access to the places where the welding must take place, as seen in figs. 7 and 8 where these electrodes are symbolized by arrows.
  • the passages 36 can be closed off by filling with cylindrical or slightly frustoconical buffers which are forced into these passages, buffers which are preferably of the same composition as the mattress 35.
  • the embodiment according to fig. 11 to 14 is particularly simple. It is made up of two layers A7, B7, each formed of a prefabricated trellis, with square or rectangular meshes, and of a bracing member which is a sheet of prefabricated trellis C7 formed of wires in a zig-zag pattern as in the case of FIG. 9, and of perpendicular rectilinear wires, parallel to each other and welded to the vertices of the zig-zag, as shown in FIGS. 13 and 14.
  • This three-dimensional tablecloth C7 is obtained by accordion folding as explained with reference to FIGS. 1 and 1a.
  • the tablecloth C7 makes contact by nodes of its network, with nodes of the networks of the tablecloths A7 and B7. Welding takes place at these contact points between nodes.
  • the two flat outer plies A8, B8 are each formed by a strip of expanded metal (fig. 15) forming a network of diamond-shaped mailpieces.
  • the two networks are offset in both longitudinal and transverse directions of the bands, preferably by half a mesh, as shown in FIG. 16, to facilitate the operation of welding the plies A8, B8 to the bracing member C8 (fig. 17) which can be of any of the types described above.
  • fig. 17 it has been indicated by arrows symbolizing electrodes, how C8 is welded to A8 and to B8.
  • the phantom lines shown in fig. 16 indicate the longitudinal direction of the plies A8, B8, which corresponds to the direction of the chain in the previous examples. This longitudinal direction is that in which the metal is deployed during manufacture.
  • the embodiment according to fig. 15 to 17 has the advantage additional that the welding of each sheet A8, B8 to the bracing member C8 takes place between two metal parts only, while in the other embodiments, three superimposed wires are welded at each welding place.
  • weft threads warp threads and bracing threads.
  • the word wire must be taken in the sense of a metallic reinforcement element which may be a bar.
  • the word wire does not imply a particularly small diameter here; these are, generally, cold-drawn steel wires or bars.
  • bracing members extend in a general direction parallel to the longitudinal direction of the two plies. It is clear that these bracing members could extend in a general direction perpendicular to the longitudinal direction of the two plies, which would moreover have the advantage of simplifying the manufacture, by bringing the bracing members in place under form of elements of length equal to the width of these layers.
