Abstract
An extruded, panel unit for constructional purposes, having two sheet-like major surfaces interconnected and spaced apart by a plurality of ribs and intermediate surfaces dividing the space delimited by the major surfaces into a plurality of sub-spaces. In cross-section, the sheet-like major surfaces and the rib and intermediate surfaces form a truss-like structure and there are provided more than three sub-spaces across a plane extending substantially normal to and connecting the major surfaces.
Claims14
An extruded, panel unit for constructional purposes, comprising
- at least two sheets forming major surfaces interconnected and spaced apart by a plurality of ribs and
- intermediate surfaces which divide a space defined between said major surfaces into a plurality of sub-spaces, wherein, in cross-section, said major surfaces and said ribs and intermediate surfaces form a truss structure and wherein there are provided more than three sub-spaces across a plane extending substantially normal to and connecting said major surfaces.
An extruded panel unit, comprising:
- at least two sheets forming major surfaces;
- a plurality of ribs interconnecting the major surfaces, the ribs arranging the major surfaces in a parallel, spaced apart relationship so as to define a space between said major surfaces;
- and
- intermediate surfaces which divide the space defined between said major surfaces into a plurality of subspaces, wherein, in a cross-section perpendicular to said major surfaces, said major surfaces and said ribs and intermediate surfaces form a truss structure as a configuration of squares, and wherein more than three sub-spaces are provided across a plane extending substantially normal to and connecting said major surfaces.
