Embodiment Construction

[0017] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] Such as Figure 1 to Figure 3 As shown, a prefabricated concrete column cast-in-situ construction method includes the following steps:

[0019] A. Pre-embedded steel bar sleeve: In the short column on the independent foundation, pre-embed the steel bar sleeve according to the design size, and then pour concrete on the short column, so that the short column is provided with a number of longitudinal steel bars equal to the number of upper precast concrete column formwork , sleeve through holes at the same position;

[0020] B. Production of prefabricated concrete column formwork: binding column reinforcement on the site in advance, assembling steel formwork and steel corrugation;

[0021] C. Hoisting of precast concrete column formwork: Lift the assembled precast concrete column formwork with a lifting device, and connect the colum...

Abstract

The invention relates to a prefabricated concrete column in-situ cast-in-place construction method which includes the steps: reinforcing steel bar sleeve pre-burying; prefabricated concrete column template manufacturing; prefabricated concrete column template hoisting; cable wind rope fixing; adjustment; concrete pouring of a prefabricated concrete column template; maintenance; template removal. The method is reasonable and effective, an assembly mode and a concrete cast-in-place mode are reasonably combined, scaffolds erected in reinforcement assembling and template constructing process are omitted, a construction period is shortened, construction cost is saved, concrete molding quality is high, parts of sources can be recycled, reinforcing steel bars can be bound in indoor space, operation environments of constructors are optimized, and green construction requirements are met.

Description

technical field [0001] The invention relates to an in-situ cast-in-place construction method of a prefabricated concrete column, which is applied to storage building structural systems such as color steel plates for outer walls. Background technique [0002] For existing storage buildings, the external wall generally adopts the system of color steel plate and thermal insulation cotton, and no scaffolding is required during construction. However, when the frame column adopts a concrete structure, due to the height of the storey, scaffolding must be erected for binding steel bars and supporting formwork, causing erection Scaffolding has low utilization rate and high cost, and the binding of steel bars and supporting formwork are all open-air operations, which is labor-intensive and the working environment is harsh. However, if the columns are all prefabricated and then hoisted, since the length of the columns generally exceeds 10m and the cross-section exceeds 0.8×0.8 m, a lar...
