RELEASABLE CORNER CONNECTION DEVICE FOR HOLLOW SECTIONS

摘要

The disclosure is concerned with a corner jointing device for mitred hollow sections which have to be assembled into window or door frames. The device comprises an angle piece and at least one tightening piece which both have corresponding wedge surfaces running parallel to the longitudinal axis of the frame members and at an acute angle to the transverse axis of the respective frame members, and at least one screw inserted in the direction of a transverse axis of the respective frame member. The tightening of the screw, as a consequence of the wedge surfaces, presses the angle piece and the tightening piece against at least three walls of the frame members cavity.
