DEMOUNTABLE JOINT FOR SELF-SUPPORTING ELEMENTS

摘要

An arrangement for the demountable coupling of at least self-supporting wall elements (1) at least to one another in the orientation of the plane of the elements, without a separate frame, the elements comprising opposite outer surfaces at a distance from each other and edge portions (3, 4) transverse to these outer surfaces, and at least one stiffener (9) which produces in the element strength in the orientation of its plane. The coupling arrangement comprises members (5) which can be tightened in the orientation of the plane of the elements for pressing the elements against one another by their edge portions. The members which can be tightened are made up of a rotatable tie rod (7) extending from the first edge portion (3) of each element to its opposite, second edge portion (4), the first end (11) of the tie rod being shaped into a first hook (21) and the second end (12) of the rod comprising tigthening means for moving the rod and thereby the first hook in the longitudinal direction of the rod. In addition, the tightening means comprise in the second edge portion (4) of each element a second hook (22) which will remain in a stationary position, to a position behind which hook the first hook of the tie rod will move when the tie rod is rotated, as seen from the end of the tie rod.
