Problems solved by technology

[0004] In the traditional fully welded beam-column joint, the upper and lower flanges of the beam and the web and the column are welded on site. Although this connection is a rigid connection, the ductility of the joint is poor, and brittle failure is prone to occur in earthquakes, and on-site welding is required, which greatly affects the construction. Speed ​​and quality are not suitable for fabricated steel structures. At the same time, due to the large area of ​​the weld, it is easy to generate large residual stress, which affects the mechanical performance of the joints.
[0005] In traditional beam-column joints connected by high-strength bolts, the beam end seal plate and box-shaped columns are fastened and connected by high-strength bolts. When fastening, workers need to reach into the box-shaped columns. It is inconvenient to come, and at the same time, the screw holes will weaken the short column of the node, affecting its mechanical performance
[0006] 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

Abstract

The invention relates to a half-welding half-bolt beam-column joint connection device of an assembly type steel structure system and belongs to the technical field of structural engineering. According to the half-welding half-bolt beam-column joint connection device, a column base connecting plate, a joint short column, a joint short column upper end flange, a joint short column lower end flange and a truss beam of one side can be welded into one body in the factory; a beam end connecting plate and a truss beam end upper and lower chord rod of the other side are welded into one body in the factory; the beam end connecting plate and the column base connecting plate are connected through bolts. According to the joint connection device, welded portions can be completed in the factory, field assembly is carried out by adopting the bolts, the work of fastening of the bolts is convenient and fast, and the speed and quality of construction are greatly improved, so that the half-welding half-bolt beam-column joint connection device is applicable to the development of assembly type steel structures; meanwhile, joints of the joint connection device are rigid joints and are good in ductility and strong in load-carrying ability.

Description

technical field [0001] The invention relates to a half-welded half-bolt beam-column node connection device of an assembled steel structure system, 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. [0003] The beam-column connection is the most important node in the fabricated st...
