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. In the traditional round steel pipe column and beam full-welded joint, the upper and lower flanges of the beam and the web and column site Welding, 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 on-site welding is required, which greatly affects the construction speed and quality, and is not suitable for fabricated steel structures

The invention relates to the technical field of structural engineering, and discloses an assembled steel structure beam-column node connection device, comprising: an upper round steel pipe column, a lower round steel pipe column and a beam, the upper round steel pipe column is fixedly connected with a first column sleeve, the first column The sleeve is fixed to the first connecting plate, the first connecting plate is fixed to the first fixing plate, the lower circular steel pipe column is fixed to the second cylindrical sleeve, the second cylindrical sleeve is fixed to four second connecting plates, the second connecting plate is connected to the lower round The distance between the upper end of the steel pipe column is equal to the distance between the first connecting plate and the lower end of the upper circular steel pipe column, the second connecting plate is fixedly connected to the second fixing plate, and the beam is inserted into the corresponding first connecting plate, two opposite first fixing plates, The second connecting plate and the two opposite second fixing plates form a square frame, and are fixedly connected by bolts. The device of the invention realizes fast connection of beam-column nodes, realizes no welding operation on the construction site, and saves manpower and construction time.
Description
technical field [0001] The invention relates to the technical field of structural engineering, in particular to an assembled steel structure beam-column joint connection device. Background technique [0002] Prefabricated steel structure 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 joint is the most important joint in the fabricated steel structure system, which directly affects...
