(1) Technical field

The invention relates to a reinforced concrete lightweight board.

(2) Background technology

The floor slab is assembled with ribbed reinforced concrete prefabricated components, which can withstand two-way loads, does not require on-site formwork, and is low in cost, easy to hoist and transport. The prefabricated component with ribs comprises a concrete bottom plate and at least one concrete vertical vertical plate. The concrete vertical vertical plate stands on the concrete bottom plate and is connected with the concrete bottom plate as a whole. Usually the length of the concrete vertical vertical slab of this prefabricated component is the same as the length of the concrete bottom slab.
