Abstract

The invention discloses a method and a structure for simultaneously constructing a constructional column and a main body structure. The method comprises the following steps of (1) embedding a constructional column lap joint steel bar in a required position in the drawing; (2) binding the lower end of a constructional column steel bar cage with the embedded lap joint steel bar, and binding the upper end of the constructional column steel bar cage with a main body structure steel bar cage; (3) erecting a formwork, and putting a layer of fine sand being 50 to 60mm thick at the bottom inside the constructional column formwork; (4) meanwhile, casting cast concrete of the main body structure and the constructional column; and (5) emptying the fine sand at the bottom of the constructional column before the wall body building, then, filling the bottom of the constructional column by high-grade fine sand concrete, and completing the simultaneous construction of the constructional column and the main body structure. The construction method provided by the invention has the advantages that the secondary construction is not needed; the secondary structure and the main body structure which are difficult in construction are synchronously completed, so that the work intensity of workers is reduced; the work efficiency is improved; and the method and the structure are applicable to places with many engineering constructional columns such as multilayer and frame-shear wall structures.

Description

A kind of method that constructional column and agent structure are constructed simultaneously and structure
Technical field
The present invention relates to method and structure that a kind of constructional column and agent structure construct simultaneously, belong to technical field of building construction.
Background technology
For improving the anti-seismic performance of multistory building masonry structure, code requirement should arrange reinforced concrete post and be connected with collar tie beam by appropriate site in the masonry in house, and the common stability strengthening building, this reinforced concrete post is just called as constructional column usually.Constructional column master if it were not for bearing vertical load, but resists the transverse load such as shearing, antidetonation.Therefore, constructional column has the ability improving wall shear strength and the deformability improving body of wall and house greatly, after constructional column forms obligatory point together with collar tie beam simultaneously, can effectively limit the expansion of wall body slit and be scattered, and ensures that body of wall does not collapse.But generally need reserved horse tooth trough in existing Constructional Col-umn Construction, and adopt template to construct, this form of construction work is high to workman's technical requirements, and efficiency of construction is lower, and body of wall and constructional column can not be constructed simultaneously, affect the duration.In addition, in order to avoid the problems referred to above, constructional column is constructed according to pillar of main frame by some construction corps, when concreting, constructional column is built together with agent structure concrete, think and so both meet construction needs, in turn save artificial, in fact there are major safety risks.Because during design, constructional column does not calculate as support carriers, now constructional column is constructed by frame column, the support system of whole floor just changes, some reinforcing bar is not stressed according to design, is absolute prohibition at the scene, and some even all will order to stop work.
Summary of the invention
The object of the invention is: provide a kind of construction technology is simple, efficiency of construction is high constructional column and the method that agent structure is constructed simultaneously and structure, to overcome the deficiencies in the prior art.
The method that a kind of constructional column of the present invention and agent structure are constructed simultaneously, comprises the following steps:
(1) according to drawing requirement position pre-buried constructional column overlap joint reinforcing bar;
(2) by the lower end of constructional column reinforcing cage together with pre-buried overlap joint reinforced-bar binding, its upper end is together with the colligation of agent structure reinforcing cage;
(3) install template: when installing agent structure template, install constructional column template simultaneously, when installing constructional column template, the thick fine sand of one deck 50 ~ 60mm is placed in the bottom in constructional column template, reinforces after treating formwork erection to template;
(4) when building the concrete of agent structure, the concrete of constructional column is built together with the concrete of agent structure, and vibration compacting;
(5) before masonry panel, the fine sand bottom constructional column is emptied, then fill bottom constructional column with high grade fine sand concrete, can constructional column be completed and agent structure is constructed simultaneously.
In said method, carry out step (3) install template construction time, the bottom of agent structure template is provided with through hole, then the bottom of the upper end of constructional column template and agent structure template is fitted tightly, and constructional column template is docked with this through hole.
Further, when carrying out the concreting of step (4), concrete being built from the through hole bottom agent structure template in constructional column template, and vibrates.
Simultaneously, the invention also discloses the structure that a kind of constructional column and agent structure are constructed simultaneously, this structure comprises agent structure (1) and constructional column (2), lower floor's agent structure (1) is embedded with overlap joint reinforcing bar (4), the lower end of constructional column reinforcing cage (6) and pre-buried overlap joint reinforcing bar (4) bundle fixing, the upper end of constructional column reinforcing cage (6) is together with upper layer main body structure reinforcing bars cage (5) colligation, be provided with gap between the lower end of described constructional column (2) and lower floor's agent structure (1), in gap, be filled with fine sand (4).
Aforesaid fine sand (4) can adopt high grade fine sand concrete to replace.
Further, lower floor's agent structure (1) is provided with boring, overlap joint reinforcing bar (4) is anchored in boring.
The invention has the advantages that: constructional column and agent structure are constructed by the present invention simultaneously, not only construction technology is simple, and convenient and quick construction, cost is lower, and shaping constructional column intensity is good, and perception is good.Therefore, adopting the constructional column of construction method of the present invention, without the need to carrying out secondary construction, the most difficult secondary structure of construction and agent structure synchronously being completed, thus reduce labor strength, improve operating efficiency, be applicable to the place that the engineering construction such as multilayer, frame structure post is more.
