CONNECTING CLAMP Russian patent published in 2015 - IPC E04B9/12 

FIELD: construction.

SUBSTANCE: invention relates to improvements of design of false ceiling grids, in particular to improvements of connecting clamps for ceiling grid elements. The clamp for connection of edges of false ceiling grid guides is implemented with a possibility of connection with an identical clamp which is made of sheet metal by method of stamping and contains front and back ends, a side ledge and the ledge location behind the front end, note that the clamp is implemented in such a way that when the identical clamp is arranged in the direction opposite to the clamp, and blocks the clamp in the side direction, similar to a lapped connection, the clamp ledge is fixed in the identical clamp location and, vice versa, the identical clamp ledge is fixed in the clamp location, while at least one of the following: the ledge and the ledge location - has a boundary containing the cut edge directed from the front end of the clamp, while the named cut edge forms a sharp angle with the plane of adjacent clamp areas, the cutting is performed by means of tools containing the gap between them significantly exceeding 10% of thickness of sheet metal from which by stamping the clamp is made. The method of fabrication of the clamp is also described.

EFFECT: improvement of design of false ceiling grids.
