ENGINEERING IN GENERAL

|  | F16 |
ENGINEERING ELEMENTS OR UNITS; GENERAL MEASURES FOR PRODUCING AND MAINTAINING EFFECTIVE FUNCTIONING OF MACHINES OR INSTALLATIONS; THERMAL INSULATION IN GENERAL

|  | F16S |
CONSTRUCTIONAL ELEMENTS IN GENERAL; STRUCTURES BUILT-UP FROM SUCH ELEMENTS, IN GENERAL

|  | F16S |
Note(s) Attention is drawn to sub-class Fulltext... Hierarchy... Expanded...E04C, in which similar elements and structures, restricted to use in the building art, are to be found.

|  | F16S 1/00 |
Sheets, panels, or other members of similar proportions; Constructions comprising assemblies of such members (built-up gratings Fulltext... Hierarchy... Expanded...F16S 3/00; layered products Fulltext... Hierarchy... Expanded...B32B)

|  | F16S 1/00 |
Note(s) In 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.

|  | F16S 1/02 |
· | designed for being secured together edge to edge, e.g. at an angle; Assemblies thereof

|  | F16S 1/04 |
· | produced by deforming or otherwise working a flat sheet (honeycomb or other core members for layered products Fulltext... Hierarchy... Expanded...B32B 3/00, e.g. Fulltext... Hierarchy... Expanded...B32B 3/12, Fulltext... Hierarchy... Expanded...B32B 3/24, Fulltext... Hierarchy... Expanded...B32B 3/26)

|  | F16S 1/06 |
· · | by deforming only

|  | F16S 1/08 |
· · | by cutting or perforating, with or without deformation

|  | F16S 1/10 |
· | Composite members, e.g. with ribs or flanges attached (Fulltext... Hierarchy... Expanded...F16S 1/02 takes precedence)

|  | F16S 1/12 |
· | of substantial thickness, e.g. with varying thickness, with channels

|  | F16S 1/14 |
· | Assemblies of such members with members of forms covered by group Fulltext... Hierarchy... Expanded...F16S 3/00 or Fulltext... Hierarchy... Expanded...F16S 5/00 (such other members being for jointing only Fulltext... Hierarchy... Expanded...F16S 1/02)

|  | F16S 3/00 |
Elongated members, e.g. profiled members; Assemblies thereof; Gratings or grilles (gratings or grilles formed from a sheet or the like Fulltext... Hierarchy... Expanded...F16S 1/00, particularly Fulltext... Hierarchy... Expanded...F16S 1/08)

|  | F16S 3/02 |
· | composed of two or more elongated members secured together side by side

|  | F16S 3/04 |
· | designed for being joined to similar members in various relative positions

|  | F16S 3/06 |
· | Assemblies of elongated members (Fulltext... Hierarchy... Expanded...F16S 3/02, Fulltext... Hierarchy... Expanded...F16S 3/04 take precedence)

|  | F16S 3/08 |
· · | forming frameworks, e.g. gratings

|  | F16S 5/00 |
Other constructional members not restricted to an application fully provided for in a single class
