Multi-element constructional assembly

Abstract

A constructional assembly includes a first rigid member, such as a wood beam or surface; a metallic surface having a repetitive sequence of ridges and grooves, one side of the surface secured to one side of the rigid member, and a second rigid member secured to an opposite side of the metallic surface. The repetitive sequence of ridges and grooves may employ a variety of geometries or corrugations, inclusive of patterns which are sinusoidal, trapezoidal, saw tooth, square wave, and triangular. This assembly is exceedingly stable, light, economical, and may be readily provided with internal apertures providing pre-formed passageways thru which electrical wiring, plumbing, air ducts, data lines and the like may be readily passed during the construction of a building.

1 . A constructional assembly comprising: 
 (a) a first rigid member;    (b) a metallic surface having a repetitive sequence of ridges and grooves therein, one side of said surface secured to said first rigid member; and    (c) a second rigid member, said element secured to an opposite side of said surface.    
   
   
       2 . The constructional assembly as recited in  claim 1 , in which said surface comprises: 
 a steel sheet having a gauge in a range of about 22 to about 14.    
   
   
       3 . The constructional assembly as recited in  claim 2 , in which said sequence of ridges and grooves of said surface comprises a corrugated surface.  
   
   
       4 . The constructional assembly as recited in  claim 2 , in which said sequence of ridges and grooves defines a sinusoidal pattern.  
   
   
       5 . The constructional assembly as recited in  claim 2 , in which said sequence of ridges and grooves defines a trapezoidal pattern.  
   
   
       6 . The constructional assembly as recited in  claim 2 , in which said sequence of ridges and grooves defines a saw tooth pattern.  
   
   
       7 . The constructional assembly as recited in  claim 2 , in which said ridges and grooves define a square wave pattern.  
   
   
       8 . The constructional assembly as recited in  claim 2 , in which said sequence of ridges and grooves define a pattern of triangular ridges and flat grooves.  
   
   
       9 . The constructional assembly as recited in  claim 2 , in which said sequence of ridges and grooves of said second surface comprises ridges having a width in a range of about 15 to 75 mm depths a range of 15 to 75 mm.  
   
   
       10 . The constructional assembly as recited in  claim 2 , in which said sequence of ridges and grooves of said second surface comprises grooves having a depth in a range of about 15 to about 75 mm.  
   
   
       11 . The constructional assembly as recited in  claim 10 , in which ridges and grooves of said surface include a plurality of transverse apertures having a greatest linear dimension in a range of about 50 to about 250 mm.  
   
   
       12 . The constructional assembly as recited in  claim 5 , in which parallel opposing surfaces of said trapezoidal pattern are secured between said first and second members.  
   
   
       13 . The assembly as recited in  claim 12 , in which said first members comprises part of a floor, and said second member comprises a part of a ceiling.  
   
   
       14 . The assembly as recited in  claim 12 , in which said first and second members comprise respective sides of a wall of a building.  
   
   
       15 . The assembly as recited in  claim 14 , in which said ridges and grooves of said second surface include a plurality of apertures having a greatest linear dimension in a range of about 50 to 250 mm, 
 whereby electrical wiring, data lines, plumbing, air ducts and the like may be passed therethrough.
