Discontinuous cross-section column transferring joint and construction method thereof

Abstract

The invention discloses a discontinuous cross-section column transferring joint and a construction method thereof. The discontinuous cross-section column transferring joint comprises a joint body which is of a column structure with hollow inside, a cross steel column connected into a column structure of the joint body, an upper end circular cross-section column transition plate connected to the upper end of the joint body, an upper end circular cross-section column connected to the upper part of the upper end circular cross-section column transition plate, a stiffening rib plate I connected between the upper end circular cross-section column and the upper end circular cross-section column transition plate, a lower end square cross-section column transition plate connected to the lower endof the joint body, a lower end square cross-section column connected to the lower part of lower end square cross-section column transition plate, and a stiffening rib plate II connected between the lower end square cross-section column and the lower end square cross-section column transition plate, wherein the outer edge of the cross steel column is connected with the inner wall of the column structure. The discontinuous cross-section column transferring joint has good cross section transition, and the occurrence of stress concentration phenomenon and the generation of anti-seismic weak partscaused by the transition of discontinuous joint steel columns only by single-layer steel plates are avoided.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a key technology for the construction of a transition node of a large-scale discontinuous cross-section column. Background technique [0002] In the construction process of modern engineering projects, the steel structure is mainly produced by the factory manufacturing method, which not only shortens the construction period, but also reduces the construction cost of the project, so that the economic benefits of the entire project are significantly improved. However, the requirements for the design of steel structure joints are getting higher and higher in the construction of modern construction projects, especially the construction quality of beam-column joints, special-shaped cross-section columns, discontinuous cross-section columns and other component connection joints is very important. Therefore, it is necessary to improve and innovate the connectio...

Problems solved by technology

Once the node fails, the connected members will lose part or all of their load-bearing functions, causing local damage to the structural system or even continuous damage to the entire system.
