The assembly of elements of the type trestle to arrangements of the open air

摘要

Elements reticular trestle type, has a triangular cross section, comprising the longitudinal beams 21, 23, 25 at the corners and the bars of the voltage of the connection 27 obliquely, these elements forming was, of the brackets, of the bows and of the elements of the stiffener, and which may be associated with the elements on illumination. The longitudinal beams are equipped of stiffener shaped making it possible to receive couplings of the junction, in order to allow the embodiment of the curves and structures a line brisee a mutual inclination limited, it provides the seals 29, 30 slightly different from each other in length and adapted to come into engagement with the stiffener of the longitudinal beams corresponding to two elements a, b is angularly connecting.
