Precast member for lightweight board

Abstract

A pre-fabricated component used for lightweight board consists of at least one vertical concrete wall on a substrate and integrated with it. At least one steel bar is located in the substrate. Some lateral mould cavities with connecting piers are arranged on the vertical concrete wall. Rigid or over-linked fillers are arranged on the substrate. Some lateral concrete ribs are cast in site to go through the lateral mould cavities. At least one side surface of the vertical wall is piled with the fillers. At least pre-stressed steel bar is arranged in the upper portion of said vertical concrete wall in parallel with that one in the substrate. Some edges are formed by the extended portion of the substrate and / or the said vertical wall. It has good mechanic performance and simple structure, costs low and saves materials so as to be used for lightweight board and roof.

Description

(1) Technical field [0001] The invention relates to a prefabricated component for a lightweight board. (2) Background technology [0002] 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. When this prefabricated component is assembled to form a floor slab bearing two-way loads, the cast-in-place concrete cannot pass through the vertical slab and cannot form a connected vertical vertical slab with the concrete. At the same time, ...

AI Technical Summary

Problems solved by technology

Usually the length of the concrete vertical vertical plate of this prefabricated component is the same as the length of the concrete bottom plate. When this prefabricated component is assembled to form a floor slab bearing two-way loads, the cast-in-place concrete cannot pass through the vertical plate and cannot form a connected vertical structure with the concrete. At the same time, in the direction perpendicular to the vertical slab, various pipeline layouts need to be drilled and threaded on site, which not only wastes concrete materials, but also wastes man-hours. Moreover, after the cast-in-place concrete, the assembled floor is solid , Concrete consumes a lot of materials, and the weight of the floor slab is heavy, so it is not suitable for large-span pouring. Therefore, it is urgently needed to develop a new type of prefabricated component for lightweight slabs.
