FIELD: construction. ^ SUBSTANCE: invention relates to the field of construction, in particular, to a panel, and also o a system of panel joining. A panel, as well as a system of panel joining, with edge profiles arranged at least on two opposite edges of panels for connection of identical panels with geometric closure, such panels comprising an edge profile arranged in the form of a groove profile with an upper wall of a groove and a lower wall of a groove, and also with an edge profile arranged in the form of a cog profile with a fixing ledge available on the lower side of the cog, and this ledge in the inserted condition enters the fixing groove with latching in the lower wall of the adjacent panel groove. Edge profiles entering into each other produce a hinged joint (G), which in a connection position, both inclined upwards and downwards causes effect of panel return into the plane of its installation, besides, the upper wall of the groove has free surface at the inner side, open to the free end of the groove wall. ^ EFFECT: higher tensile strength of a panel in an installation plane. ^ 10 cl, 4 dwg |
