Cast-in-place method for small concrete members

Abstract

The invention discloses a cast-in-place method for small concrete members. The cast-in-place method comprises the following steps that S1, the following members comprising a bottom plate, side plates, end plates and glass connecting pieces are obtained firstly, wherein the bottom plate, side plates, the end plates and the glass connecting pieces are made of anti-explosion tempered laminated glass, the glass connecting pieces comprises connecting plates bending to be in an L-shaped, and sucking discs are arranged on the two mutually-vertical side faces deviating from the bending direction of the connecting plates; S2, formworks are assembled; and S3, casting is conducted, specifically, the inner sides of the assembled formworks are coated with demoulding agents, bound steel bars are put into formworks, concrete is cast, compacted by vibration through a vibrator and maintained till the strength of the concrete reaches 20%-40% of the strength when the concrete is fully hardened, the side plates and the end plates are dismantled, and the concrete members are maintained continuously till the concrete is fully hardened. The cast-in-place method has the advantages of being capable of improving the turnover rate of the formworks, high in production efficiency, favorable for reducing the labor intensity of workers, cost saving and the like.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an on-site pouring method for small concrete components. Background technique [0002] During building construction, many small concrete components need to be poured, such as lintels on doors and windows, etc. During the process of pouring concrete on the construction site, the formwork is usually pre-processed, the steel bars are placed, and then the concrete prefabricated components are poured until the concrete is completely solidified. The mold is demoulded, and then the mold is reused. The construction cost of the above pouring method is high, the efficiency is low, and the turnover rate of the mold is low. In addition, because different types of concrete members have different sizes, workers need to prefabricate multiple sets of formwork with different specifications and sizes before prefabricating the lintel, which leads to a significant increase in cost, lab...
