BUILDING STRUCTURES

摘要

A building structure is formed from a plurality of prefabricated wall panels and a plurality of prefabricated floor slabs, a lower wall panel (10) being shown interconnected with an outer floor slab (12) and mounted on a support beam (14) of an arrangement forming part of the building foundation constructed on site. The wall panel (10) has a precast concrete component (16) and a layer of rigid insulation (20) bonded to one face thereof over a liquid impermeable flexible membrane (18) which extends to such a height as to define a suitable dampproof course. The panel (10) is also prefabricated with an interior wall sheet in the form of a cement particle board (22). The floor slab (12) has a concrete component (24), a layer of rigid insulation (20) bonded to one face thereof, and a liquid impermeable membrane (28), functioning as a dampproof course, bonded to the insulation (26). When mounted on the beam (14) on site, the panel (10) and the slab (12) can be interconnected and, by way of a further membrane (30) on the beam (14), a continuous waterproof membrane is formed. The building method eliminates many of the steps currently performed on site in adverse conditions and enables those steps to be carried out in a controlled factory environment.
