Sleeve type steel-concrete beam node connecting structure and installation method thereof

Abstract

The invention discloses a sleeve type steel-concrete beam node connecting structure and an installation method thereof. The node connecting structure comprises a prefabricated column and a beam innercylinder, wherein one end of the beam inner cylinder is fixedly installed in the prefabricated column, the other end of the beam inner cylinder extends out of the prefabricated column, a beam outer cylinder fixedly connected with the beam inner cylinder sleeves the extending end of the beam inner cylinder, and a prefabricated hollow beam fixedly connected with the beam outer cylinder is arranged at the tail end of the beam outer cylinder; the beam inner cylinder is composed of two box iron parts with groove openings opposite to each other, the upper end face of the beam outer cylinder is provided with an opening communicated with a gap between the box iron parts, and the upper end face of the prefabricated hollow beam is provided with a concrete pouring opening communicated with the gap between the box iron parts. During installation, components are hoisted in place one by one, and then concrete is poured into the beam outer cylinder and the prefabricated hollow beam. The obtained sleeve type steel-concrete beam node connecting structure and the installation method thereof have the advantages of being high in strength, good in earthquake resistance and convenience to hoist.

Description

technical field [0001] The invention relates to an assembled building, in particular to a sleeve type steel-concrete beam node connection structure and an installation method thereof. Background technique [0002] The main frame of traditional buildings is made of cast-in-place concrete beams and columns, which has the advantages of diverse graphic design, integrity, and good seismic performance. However, with the gradual acceleration of construction industrialization, the disadvantages of cast-in-place concrete structures are becoming more and more obvious, such as long construction period, serious consumption and pollution. Based on the above reasons, at the same time, due to the improvement of national policy requirements for energy conservation and emission reduction, the sharp increase in labor prices, and the widespread promotion of advanced technologies in prefabricated structures, prefabricated buildings are gradually being valued and promoted. The existing prefabri...

AI Technical Summary

Problems solved by technology

However, the prefabricated beam only has cast-in-place gaps at the end, so there is still a problem of heavy self-weight. At the same time, the prefabricated beam and the prefabricated column are only connected by poured concrete, and the seismic performance of the joints is not good enough.

In addition, the overall length of the above-mentioned prefabricated beams is large, it is difficult to hoist successfully at one time, and the hoisting time is long, which affects the assembly efficiency of the entire beam column to a certain extent
