Construction method of structural column structure with concealed beam floor slab

Abstract

The present invention relates to the construction field of structural columns, in particular to the structural column structure of the concealed beam floor slab and the construction method. The structural column structure comprises: a reinforcement cage, a number of steel bars are arranged vertically in the reinforcement cage, and the upper and lower ends of the reinforcement bars are connected to the concealed beams. Floor; columnar structure, the columnar structure is made of concrete pouring, the steel bars are placed inside the columnar structure, the upper and lower ends of the columnar structure are connected to the floor; the structural column runs through two adjacent floors, and the steel bars in the structural columns of the two floors respectively It is connected as a whole, and a columnar structure is arranged around the steel bars at the junction of the two floors. The purpose of the invention of this application is to save steel bars, firmly connect with the main body, avoid steel bar displacement, reduce pouring difficulty, and reduce cost. A related construction method is also disclosed.

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...

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
