Definitions

  • the present invention relates to a prefabricated structural panel for constructing civil or industrial use buildings.
  • Structural panels are already known which are substantially constituted by a metal material armature including a thermally-insulating and/or sound insulating material plate provided for being coated by one or more plaster layers.
  • the mentioned panels have a small weight, are provided with good insulating properties and they can be easily used for quickly constructing civil and industrial use buildings.
  • These structural panels can be used as load bearing walls for small height buildings and they can be also used as buffering elements for constructing walls of comparatively high buildings, which include a reinforced concrete load bearing structure.
  • thermally insulating and/or sound insulating material plate Before performing the plastering coating operation thereof, in the thermally insulating and/or sound insulating material plate can be embedded the main part of the electric and hydraulic ducts, thereby allowing the buildings being constructed to be quickly, economically and rationally finished.
  • Prior structural panels are provided with a soft steel wire armature, welded by resistance methods, and which comprises two opposite parallel nets, which are rigidly coupled to one another by a plurality of cross-members.
  • the mentioned cross-members simply comprise metal rod pieces extending perpendicularly to the two opposite nets.
  • This type of armature or reinforcing structure has the drawback that its mechanical strength is comparatively small.
  • armature or reinforcement structures comprising two opposite nets, which are coupled to one another by rod elements arranged on alternately opposite slanted lines (cf. for example WO94/28264 A).
  • the armature or reinforcement structure comprises two opposite nets which are connected to one another by rods which are successively arranged with a slanted relationship with opposite angles (cf. for example DE 1 963946U).
  • This type of panel has a good strength since the reinforcement structure thereof has characteristics like those of a grid-like construction.
  • Yet other types of structural panels include an armature constituted by a grid-like structure formed by a continuously bent yarn, preferably with a zig-zag arrangement, with the apex portions thereof alternately welded on the two nets (cf. for example US 5058345A).
  • This type of panel is satisfactory from a technical standpoint, since it has the typical stiffness of a grid-like construction.
  • the aim of the present invention is to overcome the above mentioned problems, by providing a prefabricated unexpensive structural panels which is moreover provided with a very good structural stiffness or strength.
  • a main object of the present invention is to provide such a structural panel which also has very good thermally insulating and/or sound insulating features.
  • Yet another object of the present invention is to provide such a structural panel which can be made by easily commercially available apparatus.
  • a prefabricated structural panel for making civil or industrial use buildings characterized in that said panel comprises an armature including two facing metal nets, spaced from one another, and coupled to one another by a plurality of separate V-shaped cross elements, the two end portions of each said cross member being welded to the wires of one of the two nets and the apex portion thereof being welded to the wires of the other net, at least a thermally insulating and/or sound insulating material layer being arranged between said two nets.
  • the prefabricated structural panel according to the present invention which has been generally indicated by the reference number 1, comprises a metal wire armature, which includes two metal nets 2, arranged with a facing relationship and spaced from one another, said nets being coupled to one another by cross members 3 of V shape, the two end portions of each said cross members 3 being welded to the wires of one of the nets 2 and the apex portion being welded to the wires of the other net 2.
  • thermally insulating and/or sound insulating material layer 4 is arranged, said layer being preferably constituted by a polystyrene panel or a foamed layer of expanded polyurethane, as it will become more apparent hereinafter.
  • the armature of the prefabricated structural panel according to the present invention comprises two half armatures 2, each of which is formed by a metal net with longitudinal wires 5 and cross wires 6 which are electrowelded to one another.
  • cross-members 3 are preferably welded to the longitudinal wires, by alternating a longitudinal wire 5 with cross-member 3 and a longitudinal wire 5 provided with cross-members 3.
  • cross-members 3 are preferably mutually aligned and being arranged along lines which are parallel to the cross wires 6.
  • the two half-armatures 2 are made likewise one another by the same making system or apparatus.
  • two like half-armatures are used, which are arranged in a mutually facing relationship, with the cross-members 3 of a half-armature 2 facing the cross-members 3 of the other half-armature 2.
  • the two half-armatures 2 are assembled by welding the apex portions of the cross-members 3 of a half-armature 2 to the longitudinal wires of the other half-armature 2, as clearly shown in figures 4 and 6.
  • thermally insulating and/or sound insulating layer 4 can be embedded, by foaming operations, after having assembled the two half-armatures 2.
  • the thus obtained structural panel 1 has a very satisfactory stiffness, since it has a grid-like construction.
  • the prefabricated structural panel according to the present invention can be used like prior prefabricated structural panels, for making load bearing walls of reduced height buildings, or as a filling or buffering panel for making walls of buildings of a comparatively great height, including a reinforced concrete load bearing construction.
  • the structural panel according to the present invention has a very small weight, which allows the panel to be manually handled, without requiring any lifting apparatus.
  • thermally insulating and/or sound insulating material layer though the best results have been obtained by using foamed polystyrene and polyurethane, these materials can be replaced by other technically equivalent materials.
