Modular prefabricated concrete wall slab for buildings - is flat with horizontal and vertical semi-circular strengthening ribs

摘要

The slab is cast in a mould and is struck by simply turning the mould upside down. The mould is designed so that without alteration it can make up to six slabs of different heights. The slab (10) has a thin back plate (11) with vertical square section side ribs (16) and horizontal semi circular ribs (14). Rebates (M) are formed in the uprights at regular intervals with holes (20) to take bolts for joining the slab to adjacent units while the top and bottom of the slab have grooves for simple end fixing.
