Beam-column joint connecting device with inclined strut for fabricated steel structure special-shaped column

Abstract

The invention discloses a beam-column joint connecting device with an inclined strut for a fabricated steel structure special-shaped column, belonging to the technical field of structural engineering. The beam-column joint connecting device comprises a column, beams and the inclined strut, wherein the column is produced by welding a cross-shaped special-shaped column, a support plate and reinforcing ribs I in a factory; and the beams are produced by welding an H-shaped steel beam, an end plate and reinforcing ribs II in the factory. All welding operations of the beam-column joint connecting device are finished in the factory; by arranging the inclined strut, the rigidity and bearing force of joints can be substantially enhanced, the use amount of bolts is reduced, the external transfer of a plastic hinge is effectively realized, damaged positions of the joints are located on the beam outside the inclined strut, and the joints are protected; by arranging the support plate, the beam can be accurately located, and meanwhile, the stability of the joints is improved; by distributing the bolts, the operation of workers is easy, the fabricating speed is greatly increased, and the fabricating quality is greatly improved; and by utilizing an onsite bolt fabricating manner, the bolts can be conveniently and rapidly fastened, the construction speed is greatly increased, the construction quality is greatly improved, the industrialized production is realized, and the onsite rapid fabricating is realized.

Description

technical field [0001] The invention relates to an assembled steel structure special-shaped column-beam-column joint connection device with diagonal braces, belonging to the technical field of structural engineering. Background technique [0002] The prefabricated steel structure system refers to the building produced by manufacturing housing units or components according to uniform and standard building part specifications, and then transporting them to the construction site for assembly in place. It is characterized by light building weight, energy saving and environmental protection, fast construction speed, and high degree of industrialization. It can solve many problems such as the low level of construction industrialization in my country, low labor productivity in house construction, and low quality of traditional house products, and adapt to the development of my country's construction industry.

AI Technical Summary

Problems solved by technology

[0003] The beam-column joint is the most important joint in the fabricated steel structure system, which directly affects the construction speed and the degree of assembly of the structure. Therefore, the beam-column joints should be connected with high-strength bolts that are easy to operate as much as possible, and the bolts should be arranged as far as possible. The ground is easy for workers to fasten on site. The beam-column joints used in the existing engineering examples have the following shortcomings: In the traditional beam-column fully welded joints, the upper and lower flanges of the beam and the web and the column are welded on site. Although this connection method is a rigid connection , but the ductility of the joints is poor
