Definitions

  • the invention refers to a method for the production of a construction product composed of two parallel steel wire meshes held in position by means of transverse wire spacers and composed of a panel of insulating material placed between the steel wire meshes (Fig. 1) which method is characterised sequentially by the following:
  • the invention refers to a group of machines, operating independently to each other for the production of the above construction product, which are characterised in sequence by:
  • a FEEDING MACHINE of ready steel wire meshes produced by an ordinary machine of production of wire meshes, which is characterised by the rellocation of the wire meshes from the usual horizontal production position to a vertical one and by their placement in pairs and for every pair in parallel position to each other.
  • a WELDING MACHINE of production of steel wire meshes characterised by the fact that (a) it produces two steel wire meshes simultaneously and (b) the two steel wire meshes are produced directly in vertical position during a parallel synchronised operation of the machine.
  • a SYSTEM OF PRESSURE REGULATION applied on the welding electrodes of steel wire mesh welding machines which is characterised by the insertion between the heads of the moving electrodes and their common translation carrier of hydraulically communicating pistons so that the pressure of liquid inside them remains uniform and is regulated by an independent hydraulic system.
  • a MACHINE of ADVANCING and POSITIONING of spacing and connecting, transversely (with respect to the plane of the two steel wire meshes) steel rods which is characterised by the straightening and cutting of the steel rods and by advancing them to the space between the two parallel steel wire meshes and the insulating foamy material in-between, so that the wires "penetrate” the insulating material and are temporarily held by it.
  • a MACHINE of PRODUCTION of MEANDRIC SHAPE of WIRE from coil which, according to an embodiment, is inserted between the two steel wire meshes in the form of spacer for the positioning and supporting of the two meshes at a distance and especially for the case where no insulating material is inserted between them, which is characterised by sequential bends of a part of the wire being trapped between two pins (at each step) while a third pin, located between the previous two ones, rotates having as a center one of the said pins and bends the wire, while at the same time the other pin approaches the first one in a way that the wire is always in contact and the non-elaborated portion of the wire remains on the same straightening axis.
  • the conveyor belt (204) During the transportation of the steel wire truss by the conveyor belt (204) first a layer of sand is applied (205) covering the lower of the two steel wire meshes to a specific height and then the layer of the insulating material (206) fabricated on site, is applied on the top of sand layer covering the space between the two meshes. After the fixing of the insulating material, the conveyor belt (204) is set in motion and unloads the steel wire truss (201) to another conveyor belt (207) discharging the sand layer at the gap between the two belts. It remains thus only the steel wire truss (201) and the in- between insulating material (206). The following consist the main disadvantages of above method:
  • the mesh producing machines adjust the distance of transverse wires by adjusting the length of advancing step of the longitudinal wires (i.e. if one transverse wire was to be welded at every welding strike on the longitudinal wires, the length of advancing step of the longitudinal wires at the interval between the two welding strikes might change and, thus, it would regulate the distance between the two transverse wires).
  • the present system provides for the easy and automatic (even at every welding strike if needed) adjustment of the distance between two transverse wire spacers.
  • the method uses ready-made panels of insulating material (401) of large dimensions, preferably made of foamy insulating material. Examples of such a material are the polystyrene, polyurethane etc. (Rg. 4).
  • insulating material 401
  • foamy insulating material examples of such a material are the polystyrene, polyurethane etc. (Rg. 4).
  • the method offers two alternatives concerning the steel wire meshes used in the construction of steel wire truss:
  • the present method provides the vertical positioning (Fig. 4a) of the ready meshes (402) in pairs, at such a distance that the insulating panel(402) is freely interferred in-between, allowing predefined gaps at both sides of the panel and the meshes.
  • the two steel wire meshes (402) are placed across the insulating panel (401), leaving a predefined gap from the surface of the panel (Rgure 4b).
  • special mechanisms of straightening, cutting and positioning produce and place the transverse, connecting and spacing rods of the two meshes. These special mechanisms push the rods (402) to insert the insulating panel and penetrate it, until the two edges of each rod (403) reach the same level with the trasverse and longitudinal wires of each mesh (Rg. 4c).
  • another welding machine welds the edges of the transverse, connecting and wire spacers on the longitudinal or transverse wires (Rg. 4d).
  • the vertical production arrangement allows the easiest automation in line of any additionally required process i.e. hardening of meshes, painting, spraying of the insulating panel with protective material, zinc-plating etc.
  • the transverse wires (38) are carried by grippers located underneath the longitudinal wires and along them.
  • the grippers driven by a system of mechanisms are free to move underneath and along the longitudinal wires, also able to place all transverse wires anywhere on the welding electrode.
  • the position of placement of the transverse wire is controlled by the control system of the machine during its operation and it can be any point on the lower electrode heads.
  • the inventive element of the mechanism is its independence from the fixed electrodes (30,31) and their support base.
  • the grippers also bear the transverse wires (38) during the welding phase and free them after welding. Two transverse wires are simultaneously fed at a time, one from each side of the mesh.
  • Feeding Machine of connecting wire spacers According to this arrangement (Rg. 13) the connecting wire spacers (318) are straightened, cut and fed in turns towards the two already positioned meshes (319) and (321) with the insulating material (320) in-between and they are placed accordingly supported by the insulating material (320). The spacing rods pierce the foamy material as appropriate. 7. Connecting wire spacers' Welding Machine. According to this arrangement (Fig. 14), vertically arranged pairs of electrodes in the form of a "comb”, penetrate the openings of the steel wire meshes and engage between their successive movable and immovable electrodes, the edges of the wire spacers and of the longitudinal or transverse mesh wires. Then the movable electrodes lower and the transverse wire spacers are welded.
  • the production method of meandric shape wire refers to the bending of the wire by means of the heads (602), (604) and (606) with no rotation of the already shaped portion in every successive bending of the wire (Rg.16). More specifically, the head (604) forms the arc AA' as in Rg. (16), the head (602) remains immobilized and the head (607) moves along with the wire towards its feeding direction, forming a retrogressive motion BB' as in Figure 16.

Abstract

L'invention se rapporte à un procédé de production d'un produit de construction constitué de deux treillis en fil d'acier parallèles maintenus en place au moyen de tiges d'écartement métalliques, transversales, et d'un panneau en matériau isolant placé entre les treillis en fil d'acier. Ce procédé se caractérise par: la production simultanée de deux treillis en fil d'acier, leur positionnement en parallèle et à proximité des deux surfaces externes du panneau isolant, le positionnement des fils d'écartement transversaux entre les deux treillis en fil d'acier, le soudage des bords des fils d'écartement sur chaque treillis. L'invention se rapporte également à un groupe de machines, fonctionnant indépendamment les unes des autres, destinées à fabriquer le produit de construction décrit ci-dessus.
