Embodiment Construction

[0101]Such asFigure 1 to Figure 13As shown, a semi-assembled cast-in-situ concrete column construction method of the present invention includes the following steps:

[0102]Step 1: Integrated horizontal assembly of the steel cage and the steel template: Assemble the steel cage 21 and the steel template on the assembly platform;

[0103]The steel template includes a first L-shaped steel support template and a second L-shaped steel support template that cooperates with the first L-shaped steel support template, the first L-shaped steel support template and the second L-shaped steel The structural dimensions of the support templates are all the same. The first L-shaped steel support template includes an L-shaped steel panel 1, a secondary reinforcement layer fixed on the outer surface of the L-shaped steel panel 1, and a main reinforcement layer fixed on the outside of the secondary reinforcement layer. And a reinforcement layer fixed on the outer side of the main rib layer, the secondary ri...

Abstract

The invention discloses a construction method of a semi-fabricated cast-in-place concrete column. The construction method comprises the steps of 1, integrally and transversely fabricating a reinforcement cage and a steel formwork; 2, carrying out straight-anchorage positioning on a reinforcement cage and steel formwork integrated fabricated structure; 3, supporting the reinforcement cage and steelformwork integrated fabricated structure; 4, mounting a pouring platform; 5, removing integrated connection between the reinforcement cage and the steel formwork; 6, pouring the cast-in-place concrete column; and 7, dismantling the steel formwork. The reinforcement cage and the steel formwork are integrally and transversely fabricated, construction of the reinforcement cage and the steel formworkin a construction site is avoided, and high-altitude operation is avoided; meanwhile, overall hoisting and positioning of the reinforcement cage and the steel formwork are facilitated in the later stage; the pouring platform is arranged at the top end of the reinforcement cage and steel formwork integrated fabricated structure in a sleeving mode, so that the integrated connection between the reinforcement cage and the steel formwork is relieved conveniently, and the concrete pouring work of constructors is facilitated; formwork splicing joints are avoided, no slurry leaks, and the cast-in-place concrete column is poured and formed at a time without construction seams.

Description

Technical field[0001]The invention belongs to the technical field of semi-assembled cast-in-place concrete column construction, and specifically relates to a semi-assembled cast-in-situ concrete column construction method.Background technique[0002]With my country’s economic development, in engineering construction, there are more and more large-scale industrial plants and logistics warehouses, and more composite structures of steel, PC, and cast-in-place concrete are used. Cast-in-place concrete columns are the main load-bearing columns, and the speed of on-site production becomes a restriction The key to PC component and roof truss installation. The traditional construction techniques of scaffolding, formwork, and cast-in-place concrete are no longer suitable for the construction of large industrial plants and logistics storage. In traditional cast-in-place column construction, operating scaffolding, steel binding, formwork support, etc. must be completed at the construction site d...
