Hidden beam floor constructional column structure and construction method thereof

Abstract

The invention relates to the field of constructional column construction, in particular to a hidden beam floor constructional column structure and a construction method thereof. The constructional column structure comprises a steel reinforcement cage and a column-shaped structure, wherein a plurality of rebars are vertically arranged in the steel reinforcement cage, and the upper end lower ends of the rebars are connected with hidden beam floors; the column-shaped structure is formed by pouring of concrete; the rebars are arranged in the column-shaped structure in a penetration manner, and the upper and lower ends of the column-shaped structure are connected with the floors; the constructional column penetrates through two adjacent storeys, and rebars in separate constructional columns of the two storeys are integrally connected; and the column-shaped structure are arranged around the rebars at a junction part of the two storeys. The application of the invention aims to provide the floor constructional column structure which has the advantages that rebars are saved; the constructional column structure can be firmly connected with a main body; rebar displacement is avoided; pouring difficulty is reduced; and the cost is lowered. Meanwhile, the relevant construction method is also provided.

Description

technical field [0001] The invention relates to the construction field of structural columns, in particular to the structural column structure and construction method of a concealed beam floor slab. Background technique [0002] In the specified part of the wall of the masonry house, the concrete column is made according to the structural reinforcement and the construction sequence of laying the wall first and then pouring the concrete column. It is usually called a concrete structural column, referred to as a structural column. The seismic performance of the body structure is mainly not to bear the vertical load, but to resist the force of shear force, earthquake and other lateral loads; [0003] The upper and lower ends of the structural column are connected to the floor. In general, the floor is equipped with beams, and the beams are set under the floor. The general structural column is directly planted with reinforcement, and the two ends of the reinforcement are connect...

AI Technical Summary

Problems solved by technology

[0003] The upper and lower ends of the structural column are connected to the floor. In general, the floor is equipped with beams, and the beams are set under the floor. The general structural column is directly planted with reinforcement, and the two ends of the reinforcement are connected to the next floor. The top surface of the floor slab and the beams below the floor slab of the previous floor. At this time, the construction column formwork leaves an opening on the side of the top for pouring concrete. Fill it with concrete, and, for the case of setting structural columns between the hidden beam floors, since the beams of the hidden beam floors are set inside the floors and do not extend beyond the lower surface of the floors, when setting the structural columns for planting reinforcement, the column support The mold leaves an opening on the side of the top for pouring concrete, but after the mold is finally closed, there will be a larger gap or a circle, or the concrete cannot be filled to the top floor. At this time, the prior art is also hand-applied concrete In this case, the construction quality of the structural column will be very poor, and its effect of resisting shear force will also be affected. At the same time, there are many disadvantages in this way of planting reinforcement, as follows :

[0004] ①The drilling of the planting bars is too close, and the tying reinforcement cage cannot reach the corner, and there is a quality risk in the steel bars of the tying structural column; The steel bars of the structural columns are shifted; ③The upper and lower floors are planted in the same narrow area at the same time, and the positions of the upper and lower planted bars cannot be staggered. There is an overlapping length between the upper and lower bars of the bound steel cage, which will lead to a large waste of steel bars and increase costs; The open type is not conducive to the compactness of concrete pouring on the upper part of the structural column, resulting in a loose connection between the structural column and the main structure, and the upper part is prone to gaps, leaving quality problems

⑥ Rebar planting requires additional payment for rebar planting, which increases the cost of the project department
