Self-supporting flooring structure of prefabricated reinforced concrete panels - of trapezoidal section with lateral ribs contg. metal reinforcing rods and extruded polystyrene filling

摘要

Consisting of a series of prefabricated panels (1), of general trapezoidal section, of reinforced concrete, inside which is housed an extruded polystyrene part (2) which insulates it thermally and acoustically.In moulding this panel (1), the actual part (2) that will be attached to it is used as a mould, including in this process a framework made from rods (7) which will be located in its smaller base connected to a separating mesh, some rods (5), located longitudinally in ribs (6) that emerge from the panel and some "U" strips that merge vertically with the same rib (6).This frame projects at both ends of the panel so that that it can be joined at the back to other panels. In a moulding for a floor, the panels are connected by its ribs (6), the space between them being filled with concrete and by placing other reinforcing rods, longitudinal insulating parts can be inserted. IMAGE The structure comprises a series of prefabricated panels of trapezoidal section made of reinforced concrete and contg. an extruded polystyrene element for thermal and acoustic insulation. The element is inserted in the mould for casting the concrete, together with reinforcement formed by metal rods situated in the narrower face, together with a casting mesh, rods situated longitudinally in ribs which project from the panel and U-shaped stirrups which emerge vertically from the same ribs. The reinforcement projects from both ends of the panel for subsequent joining to other panels, which are connected laterally by ribs with the gap between them filled with concrete with additional reinforcing rods and opt. insertion of other insulating elements.
