Abstract (en)
[origin: EP1231340A2] Exhibition stands are constructed using a lattice beam comprising several parallel hollow metal sections (1, 2, 3) which are held together by lattice structures. The hollow sections are assembled to form a beam with an isosceles triangular cross-section in which the hollow section (1) at the apex is symmetrical and the two other hollow sections (2,3) are mirror-symmetrical to the plane (5Ü running between the sides of equal length of the triangle. At least part of the chambers formed in the hollow sections is provided with a slot (15, 18) open to the outside. Preferably, the hollow sections are cubes with an external circular cross section and having internal walls, which partly run radially, connecting to a central core (8).
