Reinforced concrete combination column structure and simultaneous pouring construction method

Abstract

The invention relates to a reinforced concrete combination column structure which mainly comprises an upper steel tube column, a lower steel tube column, a lining tube, connecting ring plates and a vertical connecting screw; the upper steel tube column and the lower steel tube column are connected through the lining tube, concrete air vents and concrete pouring holes are formed in the surface of the steel tube columns, the connecting ring plates are arranged on the upper steel tube column and the lower steel tube column, the connecting ring plates are put on a cross-shaped rod and are anchored through horizontal screws on ring plate connecting end plates, and are horizontally clamped through U-shaped fastening brackets connected in series on the cross-shaped rod; the upper connecting ring plate and the lower connecting ring plate are connected through the vertical connecting screw, the vertical connecting screw and the upper connecting ring plate and the lower connecting ring plate are anchored by adopting screw caps, and a regulating and positioning top support is arranged on the end of the vertical connecting screw; and beam-column reinforcements are bound at the outer peripheries of the steel tube columns and templates are erected at the outer peripheries of the steel tube columns. According to the reinforced concrete combination column structure, the connecting node of the upper steel tube column and the lower steel tube column has strong anti-shearing performance, all members are simply and conveniently assembled, and the technical and economic benefits are prominent.

Description

technical field [0001] The invention relates to a reinforced concrete composite column structure and a simultaneous pouring construction method, which belongs to the technical field of main structure construction and is suitable for the construction of a steel pipe column concrete composite column in a two-layer or multi-layer one-joint mode. Background technique [0002] A steel tube-reinforced concrete column refers to a column formed by superimposing the steel tube column concrete in the middle of the cross-section and the outer reinforced concrete of the steel tube column, referred to as a composite column. According to the cross-sectional shape, it can be divided into rectangular cross-section and circular cross-section. The internal and external components of the composite column can be constructed in different periods or in the same period. Simultaneous construction refers to pouring the concrete inside the steel pipe column and the concrete outside the steel pipe co...

AI Technical Summary

Problems solved by technology

[0003] During the construction of the steel pipe column concrete composite column, the steel pipe column is made of seamless steel pipe column, which is not cut to length. The general method of connecting the steel pipe column is to connect one layer at a time, which can effectively ensure that the concrete inside and outside the steel pipe column is poured at the same time, but there are certain disadvantages. If the one-layer-one-connection method is used, the steel pipe column must be cut off on site, and then connected to the height, which greatly increases the amount of lining pipe and the number of welding times, and the high connection position of the steel pipe column cannot be set in the core area of ​​the beam column. If the steel pipe column cannot be used, the cost will be greatly increased, and the construction period will also be greatly increased
