Embodiment Construction

[0101] Such as Figure 1 to Figure 13 As shown, a kind of semi-fabricated cast-in-place concrete column construction method of the present invention comprises the following steps:

[0102] Step 1. Integrated horizontal assembly of reinforcement cage and steel formwork: assemble reinforcement cage 21 and steel formwork on the assembly platform;

[0103] The steel formwork includes a first L-shaped steel support formwork and a second L-shaped steel support formwork matched with the first L-shaped steel support formwork, the first L-shaped steel support formwork and the second L-shaped steel formwork The structural dimensions of the supporting formwork are all the same, and the first L-shaped steel supporting formwork 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 the reinforcement layer fixed on the outside o...

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 construction of semi-assembled cast-in-place concrete columns, and in particular relates to a construction method of semi-assembled cast-in-situ concrete columns. Background technique [0002] With the development of my country's economy, there are more and more large-scale industrial plants and logistics warehouses in engineering construction, and more steel structures, PC, and cast-in-place concrete composite structures are used. The cast-in-place concrete columns are used as the main load-bearing columns, and the speed of on-site fabrication becomes a constraint The key to the installation of PC components and roof trusses. The traditional construction techniques of scaffolding, formwork and concrete pouring are no longer suitable for the construction of large industrial plants and logistics warehouses. Traditional cast-in-place column construction requires erection of operational scaffolding, steel ba...
