Steel structure beam column assembly type rigid joint

Abstract

The invention relates to a building steel structure beam column assembly type rigid joint which is characterized in that splicing plates are interactively arranged on upper flanges and lower flanges of a cantilever beam and a frame beam, and the splicing plates on the two sides are connected with the beams by welding seams in a steel structure processing factory previously. During field mounting of the joint, the splicing plates firmly welded on the two sides serve as ear plates to allow a mounting beam section to be in place quickly; after being in place, the splicing plates are connected with the upper flange and the lower flange of the beam on the other side and spliced with a web plate by bolts; and the mounting of the beam column rigid joint is accomplished. The beam column joint is wholly spliced by the bolts in a mounting field, and is reasonable in structure, definite in force transmission, high in construction efficiency and good in safety; the field mounting is in place quickly; no welding is adopted; the mounting efficiency can be improved; the risk of a fire caused by the welding is avoided; and the joint is wholly assembled by the bolts in a construction field, so that a great convenience is brought to a construction site where the construction field condition is poor and the welding cannot be carried out conveniently.

Description

technical field [0001] The invention relates to a connection mode of a beam-column node of a building steel structure, in particular to a beam-column assembled rigid splicing node. Background technique [0002] The steel structure has a series of advantages such as high strength, light weight, good seismic performance, fast construction speed, low foundation cost, small footprint, high degree of industrialization, and beautiful appearance. Compared with concrete structures, it has the characteristics of environmental protection and recyclability. It has been recognized as a green and environmentally friendly product, and it is in line with the policy of sustainable development. Developed countries widely use steel structures in housing construction. In the United States and Japan, steel structures are used Steel production has accounted for more than 30% of steel production. With the development of my country's economy and the enhancement of comprehensive strength, steel stru...
