(57) Structure of jointing element particularly for the jointing of box-type sections
(8, 9), the peculiarity of this structure (7) lays in that said structure (7) comprises
at least one pair of opposed appendixes (10a, 10b, 11a, 11b) in correspondence to
each of the jointed end pieces (8a, 9a) of a first and at least a second section (8,
9), a first and a second superposed body (12, 13) between which are inserted the above-mentioned
pairs of appendixes (10a, 10b) of such first section (8) and the above-mentioned pairs
of appendixes (11a, 11b) of such second section (9), fixing means (18) forcing such
bodies (12, 13) against the above-mentioned pairs of appendixes (10a, 10b, 11a, 11b)
in order to joint such sections (8, 9) together by means of such structure (7). The
invention solves the drawbacks found in the known state of the art, as it allows to
effect the jointing operation in simple way at low costs (ref. fig.3).
