Reinforced composite panel for building floors, walls, beams and pillars

Abstract

A composite panel for the construction of floors, walls, beams and pillars, comprising a prismatic or parallelepiped-shaped laminated structure body consisting of a plurality of corrugated sheets that are arranged in parallel planes. The corrugations of each sheet are extended in directions parallel to each other and crossed relative to those of the adjacent corrugated sheets. The valleys of the corrugations of a sheet are linked to the peaks of the corrugations of the adjacent sheet. The panel comprises perforated reinforcing tubular members that are fixed on outer surfaces of the laminated structure body.

1 . A composite panel for building floors, walls, beams and pillars, comprising a laminated structure body of substantially prismatic or parallelepiped shape comprising a plurality of corrugated sheets arranged in parallel planes, wherein the corrugations of each sheet extend parallel in directions crossing the directions of the adjacent corrugated sheets, and wherein the valleys of the corrugations of one sheet are secured to the peaks of the corrugations of the adjacent sheet, wherein the panel comprises a plurality of perforated tubular reinforcing members fixed on outer surfaces of the laminated structure body. 
     
     
         2 . The composite panel of  claim 1 , wherein at least some of the tubular reinforcing members are fixed along at least two parallel edges of the laminated structure body. 
     
     
         3 . The composite panel of  claim 2 , wherein the tubular reinforcing members are connected to one another so as to form a cage-like frame around the edges of the laminated structure body. 
     
     
         4 . The composite panel of  claim 1 , wherein the tubular reinforcing members are connected to one another by mechanical fastening means. 
     
     
         5 . The composite panel of  claim 3 , wherein the tubular reinforcing members are connected to one another at the vertices of the prism or parallelepiped of the laminated structure body. 
     
     
         6 . The composite panel of  claim 2 , wherein the tubular reinforcing members are partially accommodated in seats shaped as elongate recesses obtained along the edges of the laminated structure body. 
     
     
         7 . The composite panel of  claim 6 , wherein the seats have transversal cross-sections partially matching those of the tubular reinforcing members accommodated therein. 
     
     
         8 . The composite panel of  claim 1 , wherein the tubular reinforcing members have transversal cross-sections of rectangular or square shape. 
     
     
         9 . The composite panel of  claim 6 , wherein the tubular reinforcing members have transversal cross-sections of rectangular or square shape and that the seats of the laminated structure body each provide a pair of consecutive walls at a right angle resting against two consecutive faces of the reinforcing members accommodated therein. 
     
     
         10 . The composite panel of  claim 1 , wherein the tubular reinforcing members are embedded in a hardened covering, such as mortar or plaster, which fills their inner cavities. 
     
     
         11 . The composite panel of  claim 1 , wherein the outer surfaces of the tubular reinforcing members are recessed with respect to the outer faces of the laminated structure body. 
     
     
         12 . The composite panel of  claim 10 , wherein the hardened covering covers at least partially at least one outer face of the laminated structure body. 
     
     
         13 . The composite panel of  claim 1 , wherein the tubular reinforcing members have a closed ring transversal cross section. 
     
     
         14 . The composite panel of  claim 1 , wherein the tubular reinforcing members have an open ring transversal cross section with a longitudinally extending slit. 
     
     
         15 . The composite panel of  claim 1 , wherein the tubular reinforcing members are made of a rigid material, preferably selected from the following: steel, fibreglass-reinforced resin, polycarbonate, wood, bamboo. 
     
     
         16 . The composite panel of  claim 1 , wherein the tubular reinforcing members are obtained by bending and welding a perforated metal sheet of reticular structure. 
     
     
         17 . The composite panel of  claim 1 , wherein the tubular reinforcing members provide a substantially uniformly distributed perforations. 
     
     
         18 . The composite panel of  claim 1 , wherein the corrugated layers of the laminated structure body are made of paper-like material impregnated with artificial resin.
