Beam-column joint for fabricated concrete frame structure

Abstract

The invention discloses a beam-column joint for a fabricated concrete frame structure. The beam-column joint comprises joint units, beam units and column units; the joint units comprise cuboid concrete columns, and two or more beam connecting sections extending in the horizontal direction and vertically arranged in the middles of the concrete columns; quick inserted-connecting assemblies which arematched are arranged at the upper ends and the lower ends of each of the concrete columns and the column units and fastened through high-strength bolts; and quick inserted-connecting assemblies whichare matched are arranged at the junction of the beam connecting sections and the beam units and fastened through high-strength bolts. According to the beam-column joint for a fabricated building, thebeams and the columns are prefabricated as the whole, thus connecting between the beams and the columns and beam-columns are prefabricated together, the strength and stability of component connectionin different directions are improved, the phenomena of weak connection and instable performance between the beams and the columns due to secondary concrete pouring and bolt connection are avoided, the connecting form is simplified, and design of the joint is also simpler and more feasible.

Description

technical field [0001] The patent of the invention is a beam-column joint used in an assembled concrete frame structure. Background technique [0002] At present, concrete construction mainly adopts the method of cast-in-place concrete construction. The method of pouring concrete construction has many advantages, such as: the raw material is cheap, the construction process is more convenient and more reliable. However, there are also some disadvantages. For example, during the construction process, it is necessary to wait for the pouring of concrete for maintenance, which slows down the construction progress; the process of pouring concrete requires the cooperation of multiple workers, which consumes a lot of manpower; It is difficult to achieve precision construction; the construction process of cast-in-place concrete is also easy to cause pollution to the surrounding environment. However, the connection between different components of prefabricated buildings at this stag...

However, there are also some disadvantages. For example, during the construction process, it is necessary to wait for the pouring of concrete for maintenance, which slows down the construction progress; the process of pouring concrete requires the cooperation of multiple workers, which consumes a lot of manpower; It is difficult to achieve precise construction; the construction process of cast-in-place concrete is also likely to cause pollution to the surrounding environment

However, the connection between different components of prefabricated buildings at this stage is relatively weak, and neither the dry bolted connection nor the wet cast-in-place concrete connection can stably meet the performance requirements of the node connection.
