[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 connection structure and connection method between a steel pipe concrete column and a reinforced concrete prefabricated beam, comprising a reinforced concrete prefabricated beam, a partition, a steel sleeve, connecting angle steel and a steel pipe concrete column; Outside the main body, the end of the steel bar is connected with the partition, the first surface of the steel sleeve is connected with the steel pipe concrete column, the inside of the steel sleeve is connected with the partition and the steel bar, and the steel sleeve is matched with the partition and the steel bar After the connection, concrete is poured into the inner space of the steel sleeve, and the connecting angle steel is used for connecting the steel tube concrete column and the steel sleeve. The structure adopts the connection method of prefabricated components assembled on site, which maximizes the construction efficiency and facilitates quality 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...
