CONSTRUCTION PANEL WITH IMPROVED BLOCKING FACILITIES FOR DETACHABLE CONNECTION WITH SIMILAR CONSTRUCTION PANELS Russian patent published in 2014 - IPC E04F15/02 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, in particular, to rectangular floor panels. The panel comprises side surfaces, limited by face and base surfaces, and at least one pair of the first blocking facilities and/or the second blocking facilities made on side surfaces for detachable connection of identical panels. Blocking facilities after connection of two panels form the first connection with geometric closure "slot-comb", including a trapeziform slot, the inclined lateral side of which via the ledge changes into the lower chute lying outside the blocking facility, and also a trapeziform comb, having a semicircular ledge for arrangement in the chute. After connection of two panels the second blocking facilities form the second connection with geometric closure "slot-comb". The chute is separated from the inner wall, to which the sliding surface adjoins, reaching the edge of the chute, which is located in the lowest part of the chute close to the side surface, so that the latter continuously rises from its edge to the rounded ledge.

EFFECT: reduced stresses in areas of panel jointing.
