COMFORTABLE WIDE WALL-ADJACENT ANGLE Russian patent published in 2013 - IPC E04B9/30 

FIELD: construction.

SUBSTANCE: wide wall-adjacent angle is designed to support a ceiling board and T-shaped profiles of a suspended ceiling lattice. The angle is an assembly of an extended main angle and an extended expansion strip. The main angle has perpendicular shelves that are solid to each other and cross in a longitudinally stretching angle. One shelf is designed to fixation to a wall with an corner down, and the other one - for protrusion horizontally from the wall. The strip has a side with a width larger than the horizontal shelf width. The strip has a multilayer design. Two layers of the strip are retained together in a close parallel position with an intermediate wall integral with these layers. Parts of these two layers are arranged so that they press at least a part of the horizontal shelf of the main corner distant from the corner in a friction manner. The strip is assembled and is retain in a friction manner on the horizontal shelf of the main angle. The horizontal shelf of the main angle is arranged between two layers of the expansion strip.

EFFECT: elimination or reduction of warp of a wide part of an angle, reduced extent of warpage.
