Building frame structure

Abstract

The invention discloses a building frame structure, and belongs to the technical field of building structure engineering. The building frame structure comprises four vertical columns, beams, L-shaped plates and supporting plates, the beams are connected with the adjacent vertical columns, the vertical columns are concrete filled square steel tubes, the beams are H-shaped steel beams, the L-shaped plates are symmetrically arranged on two sides of web plates of the H-shaped steel beams, the supporting plates are positioned below the H-shaped steel beams, one outer L-shaped surface of each L-shaped plate is welded on the corresponding square steel tube, the other outer L-shaped surface of each L-shaped plate is connected with the web plates of the H-shaped steel beams in a bolted manner, 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, vertical reinforcing plates are arranged on the bottom surfaces of the supporting plates, and the top surfaces of the supporting plates are connected with lower flange plates of the H-shaped steel beams in a bolted manner. The building frame structure 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 structure. Background technique [0002] In the existing building frame, the steel beam-steel column connection node is one of the important contents of the building structure design. The overall performance and the load-bearing performance of its connected components. At present, the connection joints between CFST columns and steel beams mainly adopt the outer ring plate type, the through-center type, and the anchor plate type. The outer ring plate joints with better performance are mainly used in the project, but the processing is complicated, the welding workload is large, and the construction is inconvenient. The outer ring plate also affects the appearance and the use space. Nodes will also affect the appearance and structure of the building. In some structures, connecting plates are welded at the ends of H-shaped steel beams and 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.
