Structure and method for making a frame structure with supporting cross sections and process by which to manufacture it

Abstract

A frame structure and process for its manufacture wherein supporting cross sections (1 a ) with at least one angle joint (11-19) and with reinforcing elements (4 a , 5 a ) arranged at a right angle to the angle joint. The reinforcing elements are structural plates or corrugated sheets in which the structures or corrugations run in the longitudinal direction of the angle joint and wherein the corrugated sheets have a lattice work like or lamellar like cross sectional form in the transverse direction.

What is claimed is:  
     
         1 . A frame structure having supporting cross sections, said frame structure comprising: 
 at least one angle joint; and    reinforcing elements that are arranged at a right angle with respect to said angle joint, said reinforcing elements having structures that extend in the longitudinal direction of the angle joint, and said reinforcing elements also having a lattice work like cross sectional form in the transverse direction, said reinforcing elements being conjoined on the open sides over several angle joints to a frame structure in a form fitting, power adhering manner.    
     
     
         2 . The frame structure of  claim 1  wherein said reinforcing elements comprise structural plates.  
     
     
         3 . The frame structure of  claim 1  wherein said reinforcing elements comprise corrugated sheets with corrugations that extend in the longitudinal direction of the angle joint.  
     
     
         4 . The frame structure of  claim 3  wherein said reinforcing elements have a lamellar like cross sectional shape in the transverse direction.  
     
     
         5 . The frame structure of claims  1 ,  2 ,  3 , or  4  wherein each of said angle joints define angle sections that encompass the open ends of the corrugated sheets with butt strap like elongations.  
     
     
         6 . The frame structure of  claim 5  wherein the angle sections are composed of metals, plastics or compounds.  
     
     
         7 . The frame structure of  claim 6  wherein the angle joints are composed of extrusion metals or pultrusion plastics.  
     
     
         8 . The frame structure of  claim 7  wherein the angle joints include hollow sections having incisions ( 20 ) or elongations ( 21 ) for form closing jointing with the supporting cross sections.  
     
     
         9 . The frame structure of  claim 8  wherein the angle joints are vertical supports, said frame structure further comprising: 
 a respective base plate corresponding to each of said angle joints; and  
 at least one supporting flange that is secured horizontally to the angle joints.  
 
     
     
         10 . The frame structure of  claim 9  wherein the corrugated sheets have corrugations that include wave crests and wave troughs, said corrugated sheets having a plurality of securing points on said wave crests or wave troughs, within the supporting cross sections, to prevent torsion of the structural plates and corrugated sheets.  
     
     
         11 . A process for manufacturing a frame structure having a supporting cross section, said process comprising the steps of: 
 Cutting at lease one section of corrugated sheet such that the section defines a generally rectangular surface having major and minor dimensions, the major dimension of the surface having an axis, with the direction of said axis being substantially parallel to the direction of the corrugations in the corrugated sheet:    Arranging a plurality of said corrugated sheet sections in parallel and securing the wave crest points that are contiguous by fastening means;    Forming the corrugated sheet sections into an arc-shape, wherein said sheet sections are formed such that the bending radius lies in the sheet plane of the corrugated sheet sections;    Placing the corrugated sheet sections in the angle joints such that the sheet sections urge against the end sections of the wave crests and join with the open structure in a closing manner; and    Assembling angle sections at the angle joints, said angle sections being parallel to the corrugated sheet section and not fastened to the corrugated sheet section such that said angle sections operate as flange planes.    
     
     
         12 . A process for manufacturing a frame structure according to  claim 11 , said process comprising the additional steps of: 
 impregnating the glass fiber reinforced plastic laminate (GFK); and    molding the corrugated sheets to be power adhering into the conjoining site, to the lattice work like or laminar like cross sections.    
     
     
         13 . A process for manufacturing a frame structure according to  claim 12  wherein the supporting cross sections are laminated into the angle joints.  
     
     
         14 . A process for manufacturing a frame structure according to  claim 13  wherein the laminate includes at least one layer at the conjoining site between the supporting cross section and the angle joint, said laminate being conjoined, in a power adhering manner, with the wave crests of the corrugated sheets of the supporting cross sections.  
     
     
         15 . A process for manufacturing a frame structure according to  claim 13  wherein the laminate includes at least one layer at the conjoining site between the supporting cross section and the angle joint, said laminate being conjoined, in a power adhering manner, with the base of the corrugated sheets of the supporting cross sections.
