Building panels and building system using such panels

Abstract

A wall panel system has at least one panel with face sheets of compressed solid cement or gypsum based material bonded to a foam core. The core has at least one channel extending through the core on an axis along the length of the panel from a predetermined position on a top edge to a bottom edge of the panel. A slot is provided on opposed side/end edges of the core to allow for a strengthening rod to be inserted between adjacent panels. An edge recess extends along one or more edges of the panel between the rear of the face sheet(s) and the core. The recess can receive and discretely hide connecting panel/plate members connecting adjacent panels.

         11 . The panel according to  claim 1 , comprising an external channel extending along the length of one or both edges of the panel between the end faces. 
     
     
         12 . The panel according to  claim 11 , each external channel being half the cross section of said at least one aperture through the at least one material. 
     
     
         13 . The panel according to  claim 1 , the first and/or second face of the panel comprising a respective recess adjacent a peripheral edge thereof. 
     
     
         14 . The panel according to  claim 13 , wherein the recess is between 20 and 50 mm wide and between 2 mm and 5 mm deep. 
     
     
         15 . The panel according to  claim 1 , comprising one or multiple apertures through a core material from one edge to the opposite edge. 
     
     
         16 . The panel according to  claim 1 , having a sandwich construction, with a core of a thermal insulation material and the first and second faces formed of sheet material. 
     
     
         17 . The panel according to  claim 16 , the insulation material comprising a foam material. 
     
     
         18 . The panel according to  claim 1 , further comprising a core, wherein the first and second faces are formed of a sheet material, and are bonded to the core by adhesive. 
     
     
         19 . The panel according to  claim 1 , further comprising sheets of a core material, wherein the first and second faces are formed of a sheet material extending over a peripheral recess around the edges of the face of each sheet of the core material. 
     
     
         20 . A building system comprising multiple panels according to  claim 1 , and connection means to retain adjacent panels together.
