LIGHTWEIGHT BUILDING PANEL WITH HIDDEN WAY OF FASTENING AND PROCESS FOR CARRYING OUT THE HIDDEN JOINT THEREOF

摘要

A lightweight building panel with a hidden way of fastening and a procedure for carrying out a hidden joint of the lightweight building panels solve the problem of hidden fastening of two adjacent lightweight panels made of a softer core, the problem of insufficient mechanical properties of the hidden way of fastening as well as the fire resistance of such a way of fastening. The essentials of the invention are the use of an underlay element (5) and an overlapping joining part (4) as well as the shape of the joint, which enable the connection of the linings (e.g. sheet metal) of the left and the right panel to an additional joining element (10). The underlay element (5) and the additional bolt (10) improve the joint properties from the point of view of bearing capacity and fire safety.
