STIFFENING JOINT WITH EXPANDABLE SCREW-NUT MECHANISM
The present invention pertains with a stiffening joint with expandable screw-nut mechanism intended to inner blocking of some sides of mechanical structures which put together tubular members in order to work or to be stiffened for correct achievement of some technological operations as the surface welding with partial melting of prefabricated doors or window corners, by example of plastics. The stiffening joint with expandable screw-nut mechanism consists of an expandable nut ( 1 ) and a conical threaded screw (2) which penetrates in some intermediate elements (3a respectively 3b), the nut ( 1 ) being of plastics with many holes bordered of some segments (c, d, e, respectively f) and some walls as elastic membranes and where is introduced a conical screw (3) driven until the moment when the nut ( 1 ) blocks in the hole of tubular profile where it will be stiffened.
