Concrete floor panel structure - has prestressed concrete, beams held in position by end spandrels and has panels holding in insulation

摘要

The floor panel (300) is made of concrete and consists of parallel beams (3011, 3012) made of pre-stressed concrete onto which is placed insulation material and a second section. A third section or ceiling is placed on the first section with insulation inserted. The beam (3011, 3012) have vertical side surfaces (302, 303) a top (304) and bottom (305) surface and smooth or rough front and back (306). The beams are held in place by end spandrels (308) each of which consists of a sheet with holes in for the beams to go through. The panel comprises floor tiles (319) preferably made of glass fibre concrete and generally rectangular in shape. A hole (326) in the edge (322) of the floor panel has inserted through it a suspension bar (340) the head (341) of which is countersunk. The ceiling panel is rectangular. An insulating medium is inserted between the adjacent panels (300).
