Lightweight composite floor panel - consists of section with girders of concrete, with cellular filling material and reinforcements
Реферат: The building panel, especially flooring panel, consists of one section with parallel girders (31) preferably made of reinforced or prestressed concrete. The space between them is filled with a cellular material partially enclosing the girders and forming a slab (70). The cellular material (31) may be concrete, or calcium sulphate. The panel has reinforcements (60, 50) embedded in the filling material and extending between the girders (31). One reinforcement (50) is trough shaped, with a flat bottom (51) situated below the underneath surfaces (39) of the girders (31). The other reinforcement (60) is a bar of lattice above the upper surface of the girders between which it is positioned. The upper surface of each girder has pieces (30) for lifting.
