<p>Trestle type reticular Components with triangular cross section, with longitudinal beams (21, 23, 25) at the corners and with connection tension bars (27) slanting; these components form stanchions, brackets, arches and terminals and may be associated with lighting elements. The longitudinal beams are equipped with molded ends in order to fit joint couplings; in order to allow the realization of cambers and broken line structures with limited mutual slant, joints (29, 30) are provided slightly different in length one from the other and suitable to be engaged at the ends of the corresponding longitudinal beams of two components to be connected angularly. <IMAGE></p> |
