FIELD: building units, particularly for arranging floor plating. ^ SUBSTANCE: panel member comprises two the first sides and two the second, end, sides. One side of the first sides has a groove, another one has ridge placed at an angle to laying plane of the first, similar, panel member. Ridge may be inserted in groove of the first member so that panel member may rotate by longitudinal edge thereof and about longitudinal edge into plane of the first panel member laying. The second sides are provided with fixing means made as end groove and end ridge which provide connection of two adjacent panel members. End groove and end ridge may be connected one to another by applying force to pull panel member down on similar previously laid panel member so that panel member is protected against the action of lifting forces directed substantially perpendicular to lying plane. ^ EFFECT: provision of gapless panel members laying and increased reliability of their connection. ^ 12 cl, 13 dwg |
