Prefabricated reinforced concrete beam-column edge joints

Abstract

The invention discloses a prefabricated assembled reinforced concrete beam-column edge joint, which is convenient in construction and simple and reliable in structure. The prefabricated assembled reinforced concrete beam-column edge node of the present invention is used to connect the prefabricated reinforced concrete beam (1) and the reinforced concrete column (2), and includes a column wall detachably fixedly connected to the side of the reinforced concrete column (2) A steel sleeve (4) fixedly connected to the front of the steel plate (3) and one end of the column wall steel plate (3); the inner diameter of the steel sleeve (4) matches the outer diameter of the prefabricated reinforced concrete beam (1); At least one side wall of the steel sleeve (4) is provided with a longitudinal notch (5), and the prefabricated reinforced concrete beam (1) is provided with a pre-embedded steel plate (6) near the end, and the pre-embedded steel plate (6) protrudes On the side wall of the prefabricated reinforced concrete beam (1), the notch (5) of the steel sleeve (4) can be inserted.

Description

technical field [0001] The invention belongs to the technical field of assembled building components, in particular to a prefabricated assembled reinforced concrete beam-column edge node. Background technique [0002] In recent years, my country's economic aggregate has increased rapidly, and the scale of capital construction has been at the forefront of the world. The demand for the industrialization of the construction industry is becoming more and more urgent. The state has also issued policies to vigorously develop and promote prefabricated buildings, starting from land transfer links, financial subsidies, preferential tax policies, etc., to encourage developers to develop prefabricated buildings. The prefabricated assembly structure system is conducive to the development of building industrialization, saving resources and energy, reducing construction pollution, and improving labor production efficiency and quality and safety levels. This is also a hot spot that has att...

AI Technical Summary

Problems solved by technology

[0004] 1. The current prefabricated reinforced concrete buildings are constructed by pouring concrete or cement slurry to connect the beam and column nodes. The column nodes are prone to connection problems, that is, the node errors are caused by the size deviation of the frame beam and column components. It is relatively large, and the concrete vibration is more difficult due to the small space for joint construction operations. The performance and quality are affected and limited by the quality of on-site construction, and the advantages of the prefabricated structure have not been fully utilized.

[0005] 2. The node design is more complicated, and the replacement of accessories is also more difficult
