The invention relates to a tower-type modular structure made of cardboard, consisting of: tray modules (a) which each consist of a cardboard template having a central portion (10) in the form of a quadrilateral, the corners of which form incoming vertices (12) and the sides of which form folding lines (13) for connection to respective flaps; straight tubes forming post modules (b), which have the same cross-section as the peripheral tubular edges (11) of each tray module (a); and connecting parts in the form of corner intersections (c), each of which has a central part (30) with arms (31), (32) and (33) projecting in three spatial orthogonal directions, which fit into the concurrent ends of the tubular edges (11) of each tray module (a), and the corresponding ends of the tubes forming the post modules (b). |
