Building frame with high-stability beam-column joints

Abstract

The invention discloses a building frame with high-stability beam-column joints, and belongs to the technical field of building structure engineering. The building frame comprises four vertical columns, beams and two supporting plates, the beams are connected with adjacent vertical columns, the vertical columns are concrete filled square steel tubes, the beams are H-shaped steel beams, the supporting plates are positioned above and below the H-shaped steel beams respectively, one end of each supporting plate is a convex inserting end, the square steel tubes are provided with jacks matched with the inserting ends, the inserting ends are inserted into the jacks and welded on the square steel tubes, a vertical reinforcing plate is arranged on one surface of each supporting plate, the other opposite surface of each supporting plate is a mounting surface, and the mounting surfaces of the two supporting plates are connected with upper flange plates and lower flange plates of the H-shaped steel beams in a bolted manner. The building frame is higher in stability, and connectors are convenient to manufacture.

Description

technical field [0001] The invention relates to the technical field of building structure engineering, in particular to a building frame with high stability beam-column joints. Background technique [0002] In the existing building frame, the steel beam-steel column connection node is one of the important contents of its architectural structure design, and the steel beam-steel column connection node is one of the important contents of the building structure design, and the steel beam-steel column connection node is The important parts that transmit bending moments and shear forces directly affect the overall performance of the structure under load and the bearing performance of its connected components. At present, the connection joints between square concrete filled steel tube columns and steel beams mainly adopt outer ring plate type, core type, anchor plate type and other nodes. In the project, the outer ring plate joints with better performance are mainly used, but the ...

Problems solved by technology

In the project, the outer ring plate joints with better performance are mainly used, but the processing is complicated, the welding workload is heavy, and the construction is inconvenient. The outer ring plate also affects the appearance and usable space. At the same time, these connection methods are expensive. For side columns and corner columns The joints will also affect the aesthetics and structure of the building. In some structures, the connecting plate is welded at the end of the H-shaped steel beam and then welded to the steel column through the connecting plate. The bending moment is large and the stability is poor.
