<p>The device assembles hollow-section members (2) end to end, which belong to two frame elements, by means of an internal splice piece (7) of corresponding cross-section. The splice piece (7) is fixed to each member (2) by two connection pins (18, 19, 27, 28) which are orthogonal to each other and pass through bores (12, 13, 14, 15) in the splice piece (7) and other bores (16, 17, 25, 26) made in the members (2). Each connection pin is provided with means for immobilising it in translation and in rotation (21 to 24; 39 to 48). This device applies in particular to the assembly of the tower elements of a tower crane. <IMAGE></p> |
