FIELD: construction, particularly covering panels for wall and ceilings. ^ SUBSTANCE: panel comprises face, rear and side surfaces provided with connection members to connect one panel with other similar ones. The first connection member comprises groove created by two edges. One edge has length exceeding that of another one and comprises rounded end. Another edge is hollow and is beveled so that bevel faces inwards. Another connection member has edge with flat part creating common plane with face panel surface and hollow side figured spike connected to side surface of the edge of the second connection member. Long edge of the first connection member is hollow and has inner longitudinal partition extending at 45-90° angle to edge surface. Side edge surface of the second connection member has beveled end. Side figured spike is connected to the beveled end. The figured spike has longitudinal extension of semi-elliptical or trapezoid cross-section secured to spike end. ^ EFFECT: decreased gaps between connection member edges at face sides of the panels. ^ 4 dwg |
