Reinforcing bar lightweight concrete borad

Abstract

A lightweight reinforced concrete comprises concrete cast in site, pre-fabricated components as fillers, which are spaced each other, contained in the former and on a substrate. Some ribs are cast in site between the said fillers. At least one steel bar is located in the substrate along the direction same as the vertical wall. Some lateral mould cavities on the vertical walls are equipped with connecting piers. At least one pre-stressed steel bar is arranged in the vertical wall in parallel with the steel bar located in the substrate. Between the lateral rib-cavities are formed to connect with the said lateral mould cavities, where some concrete is cast in site to form internal ribs connected with the said ribs. The concrete can be used as hollow roof, basement and wall.

Description

(1) Technical field [0001] The invention relates to a reinforced concrete 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, in the dir...

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.
