Problems solved by technology
[0003] The connection joint composed of steel pipe concrete column and reinforced concrete prefabricated beam is a connection joint widely used in the construction industry, but the traditional connection joint passes the steel bar through the steel pipe column to form a through bar, which is easy to weaken the force of the steel pipe column Effect, it is difficult to pour concrete in the square steel pipe, and the manufacturability is poor
In addition, the joint welding components have a large workload on site, high welding quality requirements, complex processing, and brittle failure.

Embodiment Construction
[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments of the present application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present application.
[0029] figure 1 , image 3 The connection structure between the steel pipe concrete column and the reinforced concrete prefabricated beam is shown. The steel bar inside the reinforced concrete prefabricated beam 2 extends to the outside of the main body of the prefabricated beam. The protruding length is calculated and set according to the cross-sectional size of the prefabricated beam. 5 is drilled with a through hole, and the reinforci...

The invention discloses a steel tube concrete column and reinforced concrete precast beam connection structure and a connection method. The structure comprises a reinforced concrete precast beam, a partition plate, a steel sleeve, a connection angle and a steel tube concrete column. Steel bars in the reinforced concrete precast beam extend to the exterior of a precast beam body, the tail ends of the steel bars are connected with the partition plate, the first face of the steel sleeve is connected with the steel tube concrete column, the interior of the steel sleeve is connected with the partition plate and the steel bars in a matched mode, after the steel sleeve is connected with the partition plate and the steel bars in the matched mode, the internal space of the steel sleeve is filled with concrete, and the connection angle is used for connecting the steel tube concrete column and the steel sleeve. According to the structure, a connection mode that prefabricated parts are assembled on site is adopted, the constriction efficiency is improved to the greatest extent, and the quality is easy to control.
Description
technical field [0001] The invention relates to the field of construction engineering, in particular to a connection structure and connection method between a steel pipe concrete column and a reinforced concrete prefabricated beam. Background technique [0002] The beam-column joint is also called the joint core area, which plays the role of transferring load and connecting beam-column in the structure. Most of the structural damage in earthquakes occurs at the beam-column joints, or the collapse of the entire structure is caused by the damage of the beam-column joints. Therefore, the connection properties of the beam-column joints play a decisive role in the stability and overall performance of the entire structure. [0003] The connection joint composed of steel pipe concrete column and reinforced concrete prefabricated beam is a connection joint widely used in the construction industry, but the traditional connection joint passes the steel bar through the steel pipe colu...
