Precast concrete tubular column steel reinforced concrete beam joint structure and construction method thereof

Abstract

The invention discloses a precast concrete tubular column steel reinforced concrete beam joint structure and a construction method thereof. First insertion cylinders fixedly extend out of the two sides of a concrete tubular column; insertion cylinders are fixedly arranged in a steel reinforced concrete beam; connecting blocks in the first insertion cylinders at the two sides are fixedly connected through steel wire pull ropes; the side wall of the concrete tubular column is provided with a buffer groove allowing a second insertion cylinder to be movably inserted; the outer side of the second insertion cylinder is fixedly connected with an elastic block; the second insertion cylinder is rotatably connected with a first adhesion plate; and a second adhesion plate is fixedly connected in the buffer groove. In the use process, through cooperative arrangement of the second insertion cylinder, the elastic block and the buffer groove, the connection stability and the anti-seismic buffer capability are improved; and through cooperative arrangement of a hydraulic push plate, a trigger assembly and a piercing assembly, the first adhesion plate and the second adhesion plate are fixedly connected through gluewater, and the connection stability between the second insertion cylinder and the buffer groove is improved.

Description

technical field [0001] The invention relates to the technical field of concrete beam and column assembly, in particular to a prefabricated concrete pipe column steel-reinforced concrete beam node structure and a construction method thereof. Background technique [0002] In the prefabricated concrete structure, the beam-column joint refers to the joint between the precast concrete column and the precast concrete beam. The joint plays the role of load and seismic energy consumption. The safety and reliability of the beam-column joint is the premise to ensure the normal operation of the structure. The traditional transfer-type concrete structure method is relatively simple, the use of stirrup materials is relatively frequent, and the operation is troublesome. [0003] In the prior art, the application number is "201210159381.9", a prefabricated concrete pipe column steel reinforced concrete beam node structure and its construction method, including prefabricated concrete pipe c...

Problems solved by technology

[0004] However, there are still major defects in the existing technology, such as: the steel reinforced concrete beam lacks a shock absorbing mechanism, and when the steel reinforced concrete beam is subjected to a large shear force, it is easy to make the structure at the joint between the steel reinf
