<p>The structure has rear sections (20a, 20b), front sections (21a, 21b), longitudinal sections (22a, 22b, 23a, 23b) and transversal sections (24, 25, 26) which are assembled between them for defining openings. A glazed upper panel (4) is inserted in one of the openings. The sections comprise slides for assembling the panel. Sleeves (30a, 30b) ensure assembling of the sections by press-fitting, where the sleeves are in L-shape, T-shape or tripod shape.</p> |
