Claim:
A structure for supporting components to form a wall, including: at least one lower profile section, fastened to a fixed support, and having longitudinal recesses on each side thereof; a first operating unit associated with a base of the lower profile section, the first operating unit being removably coupled at top to at least one structural element, the structural element being an upright with at least one longitudinal through hole made in it and being equipped, at an end facing the lower profile section, with at least one foot, shaped to form at least one protrusion for coupling, when the first operating unit is rotated about a vertical axis, with the longitudinal recesses by engagement to at least the protrusion with a matching portion of the longitudinal recesses to form a bayonet joint between the first operating unit and the lower profile section, the first operating unit including: a base member having the foot made on it; a connector pressed into the hole in the upright; and means for joining the base member and the connector to each other to form a rigid assembly consisting of the lower profile section, the first operating unit and the upright, and, a further structural element consisting of a crosspiece, a clamp for joining said two structural elements to each other and comprising: two jaws hinged to each other at first ends by hinge means designed to fasten the jaws themselves to an inside portion of an end of the crosspiece; locking means, provided at ends of said jaws protruding from the crosspiece for coupling with retaining means made on the upright, with said jaws abutting against pins having equal height, arranged on the connector around the hole; spreading means being provided to interact with the jaws in such a way as to cause the locking means to move apart, thereby pressing said locking means against said retaining means so as to lock the crosspiece to the upright.
