PANEL Russian patent published in 2022 - IPC E04F15/02 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, namely to panels. The panel contains a core, top and bottom sides and at least one pair of complementary edges located opposite each other in the lower part of the panels, provided with complementary locking means (V), which, in the connected state of the two panels, provide the blocking action of the panel edges in the direction perpendicular to the panel surface, and in the direction of the plane of the panels. The upper part (A) on each edge of the panel of the pair of edges contains a break in the edge, in the connected state of the two said panels, forming a recessed joint. The fractures of the complementary edges of the panel are of different magnitude, and in the connected state of the two panels, the larger edge fracture is overlapped by the smaller edge fracture, and a blunt interface is provided at the lower end of the larger edge fracture.

EFFECT: increase in operational reliability.
