Construction structure and method of large-section steel-reinforced concrete column and beam node

Abstract

The invention discloses a construction structure and method of a large-section steel-reinforced concrete column and a beam node, and relates to the technical field of building structures. According tothe technical scheme, the construction structure of the large-section steel-reinforced concrete column and the beam node comprises a steel skeleton group and a beam steel bar group which are of column structures, wherein the steel skeleton group is cross-shaped; two welded plates are arranged at the connecting part of the steel skeleton group and the beam steel bar group in parallel, and respectively correspond to the upper edge and lower edge of the beam steel bar group; through holes are reserved in the middle parts of the welded plates; a plurality of sleeves are horizontally arranged on the upper surface and lower surface of the bodies of the welded plates; the sleeves are fixedly connected to the welded plates; and threads corresponding to the steel bars of the beam steel bar group are arranged inside the sleeves. The construction structure and method have the beneficial effects that the welded plates and the sleeves are combined according to the technical scheme, and T-shaped steel is used as the steel skeleton group, and thus, the problem of the penetration of longitudinal main bars of the beam is solved; the penetration of the column beam structure can be realized withoutpunching on a web plate; and compared with the traditional process, the construction structure and method have lower requirements for steel blanking and are not prone to cause wasting in addition to the simple process.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a construction structure and method at the joints of large-section steel-concrete columns and beams. Background technique [0002] With the rapid development of economic level and cultural level, the design and construction of urban buildings are developing in the direction of "super high-rise and large span". The superior properties such as fire resistance and excellent energy-saving effect are widely used in such projects. [0003] Since the steel-concrete composite structure integrates the steel structure and the reinforced concrete structure in a very small section size, the connection part of the beam-column joint is an important part of the force transmission and form conversion, and the force-bearing reinforcement of the column and beam is required to be carried out here. Through, it is necessary to pass through the steel frame or connect in an effective way. ...

AI Technical Summary

Problems solved by technology

[0004] When engineering design beam-column reinforcement is dense, the diameter of the reinforcement is large, the size of the steel reinforcement in the steel concrete column is too large, and the operation space between the steel reinforcement column and the column reinforcement is extremely small, the traditional beam-column joint construction method cannot meet the construction requirements on site.

For example, in traditional construction, the transverse steel bar connecting the column and the beam needs to pass through the steel bone column. In this case, because it is difficult to confirm the slot position on the steel bone column in advance, it is often difficult to align the two ends of the horizontal steel bar with the beam steel bar. situation occurs
