Fabricated steel structure H-shaped steel column and beam column joint connecting device with diagonal braces

Abstract

The invention discloses a fabricated steel structure H-shaped steel column and beam column joint connecting device with diagonal braces, and belongs to the technical field of structural engineering. The fabricated steel structure H-shaped steel column and beam column joint connecting device comprises columns, beams and the diagonal braces. The columns are formed by welding cross-shaped special-shaped columns, supporting plates and stiffened ribs I in a factory, and the beams are formed by welding H-shaped steel beams, end plates and stiffened ribs II in the factory. The forms of the diagonal braces are not limited to H-shaped steels, and the types of channel steel and T-shaped steels can also be used. According to the fabricated steel structure H-shaped steel column and beam column joint connecting device with the diagonal braces, all welding work is completed in the factory; the diagonal braces are arranged, the rigidity and the bearing capacity of joints can be greatly improved, the using amount of bolts is reduced, out-shifting of plastic hinges is realized effectively, so that the broken location of the joints is located on the beams besides the diagonal braces, the role of protecting the joints is achieved; the bolts are arranged, operation for workers is also easy, the assembly speed and quality are greatly improved; bolt assembling is adopted on site, the fastening work of the bolts is convenient and quick, the construction speed and quality are greatly improved, industrialized production is realized, and on-site assembling is quick.

Description

technical field [0001] The invention relates to an assembled steel structure H-shaped steel 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.

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, brittle failure is prone to occur in earthquakes, and welding is required on site, which greatly affects the construction speed and quality. It is not used in multi-story fabricated steel structures. At the same time, due to the large welding area, it is easy to produce large residual Stress, which affects the mechanical performance of nodes

In the traditional bolted and welded joint connection, the upper and lower flanges of the beam end are welded to the column on site, and the web at the beam end is bolted to the column through a shear plate. This connection method requires on-site welding, which greatly affects the construction speed and quality, and the construction The program is complex and it is not easy to achieve rigid connection
