Dual-joint plate square steel pipe column-K-shaped steel supporting connecting joint

Abstract

The invention relates to the field of K-shaped steel supporting connecting joints in connecting joints of building structures, and discloses a dual-joint plate square steel pipe column-K-shaped steelsupporting connecting joint. The dual-joint plate square steel pipe column-K-shaped steel supporting connecting joint comprises a square steel pipe column with six bolt holes formed in the column wall, steel plates fixed to the two sides of the column through split bolts, two joint plates welded to the steel plates and steel supports connected to the joint plates through high-strength bolts. A part of web plate needs to be cut off at the end, connected with the corresponding joint plate, of each steel support. By means of the joint, the shock resistance, energy dissipation capacity and ductility of a steel framework can be improved; and field construction is convenient, and the joint meets the strong joint and weak component principle and also has necessary strength and good deformation capacity and energy dissipation capacity.

Description

technical field [0001] The invention relates to the field of K-shaped steel support connection nodes in building structure connection nodes, in particular to a double-node square steel pipe column-K-shaped steel support connection node. Background technique [0002] Prefabricated steel structure buildings have been vigorously promoted in today's construction industry. It has the advantages of design standards, industrialization of production, assembly of construction, integration of decoration, informationization of management, and intelligent application. Prefabricated steel structure buildings can reduce the pollution brought to people during construction, reduce construction costs, improve construction efficiency and quality, make construction safer, and alleviate the crisis caused by overproduction in the steel industry. [0003] Prefabricated steel structure buildings have the following advantages: ① Flexible layout and high integration of building content. The space l...

Problems solved by technology

But it is precisely because of the strong restraint ability of this kind of joint that when the support loses stability, it will generate a secondary bending moment at the joint, which not only brings trouble to the design of the joint, but also affects the low-cycle fatigue life of the support. This rigid connection method also brings some troubles to production, construction and installation.
