The butt joint is produced by means of a connecting element (3). …<??>The connecting element (3) is arranged in two grooves (14, 24) which lie one on top of the other along the butts (40, 42) of the plates (1, 2) and/or sections (1a, 2a) and which form a cavity. It consists of two spread profiles (31, 32) which are displaceable from at least one intermediate spring element (33) in the direction of the cover surfaces (122, 132, 222, 232) of the plates (1, 2) or sections (1a, 2a) and can be bonded with the corresponding walls of the grooves (14, 24). These profiles have means for the releasable locking by means of a tensioned spring element/tensioned spring elements (33), it being possible for the tension-locked spread profiles (31, 32) to be introduced into the grooves (14, 24) with clearance. …<??>The surfaces produced with the butt joints appear jointless. The use is for vehicle construction and structural and civil engineering, in particular for car bodies and panelling work. …<IMAGE>… |
