a structural system and components for housing or other structures and their methods of production . panel members serve as structural elements or as filler members or both , and in some applications can be removed . the panel members are provided with mesh on one or both sides of a heat insulation core member with the mesh being welded or otherwise affixed to i - beams or reinforced concrete reinforcing steel to form a continuous structural solution . roof panels are provided which are similar to that of the vertical walls , and the mesh on the upper surface is firmly affixed to both the columns and the reinforced concrete perimeter beam , affording a finished structure of great structural integrity . in all cases , the panels allow pouring of concrete around previously installed , reinforcing steel , allowing a final reinforced concrete structure similar to that constructed conventionally , but eliminating the extensive forming labor connected therewith .
