Patent AT-E401472-T1: [Translated] CONSTRUCTION ELEMENT, ESPECIALLY FOR THE CONSTRUCTION INDUSTRY

Structural element with composite transparent structure and improved safety characteristics, comprising at least one sheet-like portion (2, 15, 18) having, adhering to at least one section of its peripheral edge (4), particularly intended to withstand tensile stresses, at least one strip-like portion (3) so as to increase the flexural rigidity thereof and/or the toughness of the sheet-like portion. The transparent sheet-like portion (2, 15, 18) is a multilayer element consisting of several elements of transparent material such as glass and/or polymer. The transparent polymer is polycarbonate, polyurethane, polyvinyl chloride or mixtures thereof or copolymers thereof. The strip-like portion (3) adheres integrally to the edge (4) of the multilayer element subject to tensile stress and comprises one or more layers (8, 8') integral with each other. The multilayer portion comprises several transparent sheet-like elements (5, 5', 5'', 16, 16', 16'', 19, 19', 19'') between which a first layer of adhesive material (6, 6', 6'') such as polyvinyl butyral, polyurethane or a layer of intumescent material is arranged.
