Problems solved by technology

In the prior art, there is a method of pre-embedding steel structural members on prefabricated concrete beams and columns, and connecting the beams and columns through high-strength bolts at the construction site. There are many auxiliary parts for connecting beams and columns, and the connection is not convenient enough. Therefore, a beam-column structure with convenient connection and stable force transmission mechanism is needed

Abstract

The invention discloses a prefabricated concrete beam-column joint structure, which comprises a column structure, a beam structure, a first steel member and a second steel member. One end of the firststeel member is embedded in the column structure and one end of the second steel member is embedded in the beam structure. Up-down opposite bolts at a protruding end of the first steel member and theprotruding end of the second steel member are fixedly connected to form a pouring space. Concrete is poured in the pouring space. The prefabricated concrete beam-column joint structure is simple in structure, convenient for construction installation and positioning, convenient for connection, and has stable force transmission mechanism, and construction efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a prefabricated concrete beam-column node structure. Background technique [0002] In the connection of prefabricated concrete structures, the connection quality of the beam-column joint connection area is the key to ensure the integrity and seismic performance of prefabricated concrete structures. At present, the beams and columns of the prefabricated concrete structure are prefabricated in the factory, and the connection between the beams and the columns generally adopts the method of on-site secondary pouring. The prefabricated concrete beams and columns of this method require additional tools and supports on site to assist in the construction. The installation accuracy is high, and there are a large number of beam-column intersecting longitudinal bars in the connection area. The connection and arrangement of steel bars are relatively difficult, and there are disconn...
