LINEAR PANEL WITHOUT RUST Russian patent published in 2021 - IPC E04F13/12 

FIELD: industrial and civil construction.

SUBSTANCE: invention relates to the field of industrial and civil construction, namely to the technology of internal and external facing of walls and ceilings, any inclined planes in any direction, and first of all, ventilated facades of office buildings, storage facilities, sports complexes, hangars, etc. A linear panel without rustication, made of a cold-formed galvanized metal profile, contains a shelf with stiffeners and edges with profile elements to form a docking lock during installation, while the profile element of one of the edges as a pin of an elastic docking lock is made in the form of a stiffener curved inward profile, and the profile element of the other edge as a grip of the elastic docking lock is made with a bend outward parallel to the profile shelf with a place for installing self-tapping screws, then a bend molded back to the edge also with a place for installing self-tapping screws, mated with the mentioned place, and then by a bend, formed parallel to the edge by at least three quarters of the edge height to ensure the elasticity of the grip of the docking joint, while on this edge and bend there are conjugate stiffeners curved outward of the profile, and the tail part of the bend is bent away from the edge at an angle 30 to 45 degrees to ensure that the pin is inserted into the grip of the docking lock, and the axes of symmetry of the stiffening ribs of the pin and the grip are made at the same distance from the profile flange so that when the linear panels are mounted on the facade to be faced, the pin of one panel will snap into the grip of the adjacent panel, thus forming an elastic docking lock, and the folds of each linear panel will be fixed by self-tapping screws.

EFFECT: simplification of the joining elements of linear panels without rusticity, in creating an elastic docking joint with a given profile geometry, in excluding metal swelling on the front surface of the panels and in eliminating impact forces during installation, in ensuring the smoothness of the facade surface due to the fixed fit of one panel relative to the other due to the geometry of the elastic docking lock, in getting the opportunity to replace individual panels when they are damaged without large labor costs while maintaining the presentation of the facade surfaces, in reducing labor intensity during installation work.
