DEVICE FOR FIXING INSULATION TO WALL Russian patent published in 2017 - IPC E04B1/76 E04F13/08 F16B13/12 

FIELD: construction.

SUBSTANCE: device for fixing the insulation to the wall consists of a fixing sleeve (1) which ends on one end with an expansion zone (2) and on the other with a circular plate (3) where an expansion element (4) is located inside the fixing sleeve (1), preferably in the form of a screw. In this case, the expansion element (4) has a head that is integrated into a sleeve (5) with an external thread, where a polygonal hole (6) is provided in the sleeve (5). The fixing sleeve (1) has a diameter with a gradual decrease, with the largest diameter (D) being on the input side. The length (L₂) of the fixing sleeve (1) from the stage to the end of the fixing sleeve is not less than the length (L₁) of the expansion element (4) from the point of attachment to the sleeve (5) to its end. The largest internal diameter (D) of the fixing sleeve (1) is larger than the outer diameter (D₁) of the sleeve (5) rigidly attached to the expansion element (4). The length of the segment (K) with the largest internal diameter (D) of the fixing sleeve (1) is not less than the length (K₁) of the sleeve (5), which is attached to form an integral joint to the expansion element (4).

EFFECT: creation of a device with a simple design with functionality and with reliable fixing and fast installation.
