Fabricated steel reinforced concrete column-steel reinforced concrete beam joint with inner and outer steel sleeves

Abstract

The invention discloses an assembly type steel reinforced concrete column-steel reinforced concrete beam joint with an inner steel sleeve and an outer steel sleeve and an installation method. The node is mainly composed of a prefabricated upper steel reinforced concrete column with a steel inner sleeve, a prefabricated lower steel reinforced concrete column with a steel inner sleeve, a steel outer sleeve with a bracket and a prefabricated steel reinforced concrete beam with a stirrup being a square spiral hoop. Section steel of the steel reinforced concrete upper and lower columns with the steel inner sleeves is connected with the inner sleeves in a welded mode through welding rib plates, then longitudinal bars and square spiral stirrups are bound, finally concrete is poured for prefabrication forming, the upper column and the lower column are connected in a welded mode through the steel inner sleeves at the column ends, and the steel outer sleeves with corbels are reinforced through high-strength bolts and welded connection. And then high-strength bolts penetrate through the connecting joints to enable the connecting joints to form a whole, the brackets of the steel outer sleeves are connected with the prefabricated steel reinforced concrete beams through the high-strength bolts, and the beam-column joints are formed at the joints of the brackets and the beams through post-pouring concrete. According to the assembly type steel reinforced concrete column-steel reinforced concrete beam joint with the inner steel sleeve and the outer steel sleeve, the problem of connection of prefabricated steel reinforced concrete is well solved through the joint, good anti-seismic performance is achieved, a large amount of on-site workload can be reduced, and on-site assembly is facilitated.

Description

technical field [0001] The invention relates to an assembled shaped steel concrete column-shaped steel concrete beam joint with inner and outer steel sleeves in the technical field of construction. Background technique [0002] At present, most civil buildings still use reinforced concrete structure, but this kind of structure is heavy, has a long construction period, requires a lot of manpower, and consumes a lot of environmental resources. Steel-reinforced concrete (SRC) refers to a steel-concrete composite structure formed by disposing steel in the original reinforced concrete beams and columns. Compared with traditional reinforced concrete structures, it has strong deformation capacity and good seismic performance, which can reduce the cross-section of beams and columns and increase the use of Space, compared with the steel structure, concrete has both the function of bearing force and protecting the section steel, saves steel, has high structural rigidity, and is easier...
