T-SHAPED FASTENING ELEMENT FOR CLADDING PLATES (PANELS) OF SUSPENDED FRAMEWORK OF CLADDING SYSTEM FOR BUILDINGS AND PREMISES BY CONCEALED METHOD Russian patent published in 2018 - IPC E04B1/38 E04F13/21 

FIELD: construction.

SUBSTANCE: fastening element of cladding plates (panels) of the suspended framework of the cladding system for buildings and premises by concealed method is made removable and sliding and consists of a base wall and two rectangular grips (hooks) in the form of a T-section flange, located at one end of the base wall. On the other the opposite end on the two opposite sides from the axis of the base wall on each side two identical tongues (protrusions) are made. They are located symmetrically parallel relative to the longitudinal axis of the base wall at a certain distance from each other and have rounded shape on the ends of the form with the possibility of placing and rigid fixing into corresponding recesses (holes) of the rectangular groove of the extruded profile. When the T-shaped fastening element contains rectangular grips (hooks) for installing and fixing in the respective and opposite each other longitudinal cuts of the front parts around the perimeter of two adjacent symmetric opposite cladding panels (plates), not less than 4 pieces per one cladding panel (plate) (two on the bottom, and two on the top) to ensure concealed fixation and mutual fixation of the cladding panels (plates) with the extruded profile adapted to form a "tongue and groove" joint.

EFFECT: simplification of installation of cladding plates, increase of rigidity and strength of the system of fastening cladding plates of surfaces of buildings and premises, provision of reliable concealed type of cladding fastening, increase of level and quality of maintainability.
