SECURING UNIT FOR SECURING LOAD-BEARING AND THERMAL INSULATION ELEMENTS TO SUPPORTING STRUCTURES

The invention relates to a securing unit for securing load-bearing and thermal insulation elements to supporting structures, which has a pulling pin (1), a clamping cartridge (4) provided with a gripping channel (4a), a spherical hinge (6) and a clamping disc (7), where the pulling pin (1) has a tensioning cone (3) located at the one end (la) located towards the supporting structure (8) and a tension unit (2) pulled onto the pulling pin (1), furthermore the spherical hinge (6) has a supporting surface (6a), protrusion (6b) and a sleeve (6c) passing through the protrusion (6b), the clamping cartridge (4) is at least partially fitted into the sleeve (6c) of the spherical hinge (6), while the clamping disc (7) is provided with a receiving surface (7a) corresponding to the supporting surface (6a) of the spherical hinge (6) and a through-hole (7b) formed in the receiving surface (7a), with the securing unit in its use position the protrusion (6b) of the spherical hinge (6) is pushed through the through- hole (7b) of the clamping disc (7), and the supporting surface (6a) of the spherical hinge (6) is connected to the receiving surface (7a) of the clamping disc (7), and the other end (lb) of the pulling pin (1) opposite the one end (la) provided with the tensioning cone (3) is secured in the gripping channel (4a) of the clamping cartridge (4). The characteristic feature of the invention is that the inner surface (4b) of the gripping channel (4a) of the clamping cartridge (4) is provided with grips (4c), and with the securing unit in use position the grips (4c) are pushed into the material of the other end (lb) of the pulling pin (1) or the tension unit (2) pulled onto the pulling pin (1) is formed by a helically wrapped tape (2a), where the helically wrapped tape (2a) delimits a helical cavity (2b), and with the securing unit in use position the tensioning cone (3) of the pulling pin (1) is at least partially in a position of being pulled into the helical cavity (2b) of the helically wrapped tape (2a).
