Flat foldable building structural panel

Abstract

An essentially rectangular, flat, foldable building structural panel has a series of horizontal and oblique flexible joints made of silicone rubber impregnated fabric located on the inside of the panel. The horizontal and flexible joints create a series of geometric triangles that can be formed and folded into multiple configurations. The geometric configurations are composed of rigid triangular facet sections and flexible joints between adjacent edges of the triangular facet sections. Alternating the direction of the folds allows the user to create a three-dimensional freestanding structure of various dimensions and geometric configurations. Poles can be included for the purpose of raising the structure to produce a canopy. Since the triangular facets are rigid and the joints between the edges of the facets are flexible, quick erection of the structure may be accomplished. The structure is fastened to the ground by use of ground grommets and stakes. The panel consists of laminations of various fabrics, adhesives and triangular panel facets with fasteners and loops for stiffing rods and tension lines.

1 . A building structural panel, comprising: 
 (1) a flat panel having a series of horizontal foldable edges therein;    (2) a series of oblique foldable edges running across said horizontal edges oriented at an angle to said horizontal edges, said oblique edges creating a series of triangular sections;    (3) a plurality of upper structural grommets located near the center of said panel for supporting and separating said triangular sections;    (4) a plurality of ground grommets located along the outer edge of said structural panel for securing said structure to the ground.    
   
   
       2 . A building panel as in  claim 1 , further comprising horizontal structural spacers located between said upper structural grommets and a biasing means to separate said structural spacers  
   
   
       3 . A building panel as in  claim 2 , wherein said biasing means comprises a bungee cord located inside said upper structural spacer.
