Description

lightweight concrete board

(1) Technical field

The invention relates to a lightweight concrete board.

(2) Background technology

Ribbed reinforced concrete prefabricated components are used to assemble lightweight slabs, which can bear two-way loads, do not need on-site formwork, and are low in cost, easy to hoist and transport. This ribbed prefabricated component includes a strip-shaped bottom plate and a long strip-shaped side plate, and the side plate and the bottom plate are connected as a whole to form a T-shaped or long-strip trough-shaped component. Usually the length of the side slab of this prefabricated component is the same as the length of the bottom slab. When this prefabricated component is assembled to form a lightweight slab that bears two-way loads, the cast-in-place concrete cannot pass through the side slab and cannot form a connected intersecting slab with the side slab. In-situ concrete ribs, at the same time, in the direction perpendicular to the side plate, various pipeline layouts need to be drilled and threaded on site, which not only wastes concrete materials, but also wastes man-hours. Moreover, after cast-in-place concrete, the assembled lightweight panels are solid. Concrete consumes a lot of material, and the lightweight slab is heavy, which is not suitable for large-span pouring. Therefore, it is urgent to develop a new type of concrete lightweight slab.
