F16SCONSTRUCTIONAL ELEMENTS IN GENERALSTRUCTURES BUILT-UP FROM SUCH ELEMENTS, IN GENERALThis subclass does not cover similar elements and structures, restricted to use in the building art, which are covered by subclass E04C.In this subclass non-limiting references (in the sense of paragraph 39 of the Guide to the IPC) may still be displayed in the scheme. F16S1/00 F16S1/00Sheets, panels, or other members of similar proportionsConstructions comprising assemblies of such members built-up gratings F16S3/00; layered products B32BIn general shape the members may be flat or curved, but they may depart from such shape in detail over part or all of their area, e.g. they may be corrugated, ribbed, flanged; ribs, flanges or the like may be separately formed. F16S1/02designated for being secured together edge to edge, e.g. at an angleAssemblies thereof F16S1/04produced by deforming or otherwise working a flat sheet honeycomb or other core members for layered products B32B3/00, e.g. B32B3/12, B32B3/266, B32B3/26 F16S1/06by deforming only F16S1/08by cutting or perforating, with or without deformation F16S1/10Composite members, e.g. with ribs or flanges attached F16S1/02 takes precedence F16S1/12of substantial thickness, e.g. with varying thickness, with channels F16S1/14Assemblies of such members with members of forms covered by group F16S3/00 or F16S5/00 such other members being for jointing only F16S1/02 F16S3/00Elongated members, e.g. profiled membersAssemblies thereofGratings or grilles gratings or grilles formed from a sheet or the like F16S1/00, F16S1/08; frames for doors, windows or the like E06B1/00, E06B3/00 F16S3/02composed of two or more elongated members secured together side by side F16S3/04designed for being joined to similar members in various relative positions F16S3/06Assemblies of elongated members F16S3/02, F16S3/04 take precedence F16S3/08forming frameworks, e.g. gratings F16S5/00Other constructional members not restricted to an application fully provided for in a single class
