Beam flange opening weakening type node for connecting steel beam and wide concrete filled steel tubular column

Abstract

The invention discloses a beam flange opening weakening type node for connecting a steel beam and a wide concrete filled steel tubular column. According to the beam flange opening weakening type node, upper and lower flanges of the steel beam are fixedly connected with a short edge of the wide concrete-filled steel tubular column through a reinforcing plate and flitch plates, and a web of the steel beam is fixedly connected with the short edge of the wide concrete-filled steel tubular column through a connecting plate; and the wide concrete-filled steel tubular column is located in the middle of a building plane, the three steel beams are fixedly connected with the three side faces, close to the short edges, of the wide concrete-filled steel tubular column through the reinforcing plates and the connecting plates, an inserting plate is vertically inserted into the wide concrete-filled steel tubular column in the direction parallel to the short edges of the wide concrete-filled steel tubular column, and the two ends of the inserting plate are fixedly connected with the two reinforcing plates. The joint structure is easy to machine, convenience is brought to joint manufacturing, and meanwhile the steel consumption of the joint is reduced; the engineering problem that beam-column joints are prone to being damaged at joint welding seams is solved; equipment pipelines can conveniently pass through different floors through the holes in the flanges of the steel beams; and the concrete in the pipe can be ensured to have good pouring quality.

Description

technical field [0001] The invention relates to a beam flange joint connecting a steel beam and a wide steel pipe concrete column, in particular to a beam flange opening weakened joint connecting a steel beam and a wide steel pipe concrete column. Background technique [0002] At present, my country is vigorously promoting the industrialization of construction and housing. Steel structures are better prefabricated building products with extremely superior seismic performance. How to use steel structure in residential system, give full play to the characteristics of steel structure industrialization, and meet the functional requirements of residential buildings is a very important and urgent task [0003] In steel structure residences, excessively large steel column cross-sections will produce convex columns at the four corners of each functional room in the residence, which will affect the use of indoor buildings. Therefore, structural components should be hidden within the ...

Problems solved by technology

The disadvantage of this dog-bone joint is that the cutting surface of the flange is complicated to process, and experimental studies have found that out-of-plane instability is prone to occur at the weakened part of the beam section
