Fabricated concrete frame beam-column dry type connecting joint adopting bolt connection

Abstract

The invention discloses a fabricated concrete frame beam-column dry type connecting joint adopting bolt connection. The fabricated concrete frame beam-column dry type connecting joint comprises a prefabricated concrete column, a prefabricated concrete beam and two L-shaped connecting devices, each L-shaped connecting device comprises a vertical plate and a transverse plate, and the two L-shaped connecting devices are symmetrically arranged at the upper side and the lower side of the end part of the prefabricated concrete beam; and the two transverse plates are fixedly connected with the upperside and the lower side of the prefabricated concrete beam, the two vertical plates are fixedly connected with one side face of the middle of the prefabricated concrete column, two steel plates arranged on the side faces of the ends of the prefabricated concrete beam are also included, and the two steel plates and the two transverse plates are welded to form a wrapping cavity to wrap the end of the prefabricated concrete beam insides. According to the fabricated concrete frame beam-column dry type connecting joint, the L-shaped steel plates are adopted at the beam-column joint for high-ductility bolt connection, the energy dissipation capacity of the joint can be effectively improved, meanwhile, the prefabricated concrete beam is wrapped with the steel plates, the strength of the part canbe enhanced, outward movement of beam-end plastic hinges is achieved, and the deformation capacity of the joint is enhanced.

Description

technical field [0001] The invention belongs to the technical field of prefabricated concrete structures, and in particular relates to a prefabricated concrete frame beam-column dry connection node connected by bolts. Background technique [0002] Prefabricated concrete structures have developed by leaps and bounds in my country in recent years, mainly due to the industrial production of its main components, high production efficiency, energy saving and environmental protection. The prefabricated concrete frame structure is a structural system with better structural overall performance and seismic performance in the prefabricated structure, and more research and application. [0003] Existing prefabricated concrete frame structures generally use ordinary concrete and ordinary steel bars. There are generally key technical problems such as crowded joints, chaotic assembly, and difficulty in ensuring the quality of joints. Moreover, a certain length of steel bars will protrude ...

Problems solved by technology

[0003] Existing prefabricated concrete frame structures generally use ordinary concrete and ordinary steel bars. There are generally key technical problems such as crowded joints, chaotic assembly, and difficulty in ensuring the quality of joints. Moreover, a certain length of steel bars will protrude from the ends of the beams, which may easily cause assembly problems. , transportation difficulties

[0004] The above problems limit the application and development of prefabricated concrete frame structures.
