Novel sleeve-type fabricated joint of square steel tube column and H-shaped steel girder and construction method of novel sleeve-type fabricated joint

Abstract

The invention provides a novel sleeve-type fabricated joint of a square steel tube column and an H-shaped steel girder and a construction method of the novel sleeve-type fabricated joint. The novel sleeve-type fabricated joint comprises a joint area square steel tube column section, a joint area H-shaped steel girder section and a connecting piece. The connecting piece comprises a square sleeve, an H-shaped sleeve and a supporting steel plate, the square sleeve and the square steel tube column are connected through high-strength bolts, the situation that the column wall is too thin, and thus local protrusion occurs to the positions, where the bolts are located, of the square steel tube column is effectively prevented, and thus the bearing force of bolted connecting positions of the columnand the girder is increased; the H-shaped sleeve and the square sleeve are connected in a welded mode, the welding area is increased compared with a conventional mode, and thus the joint is firmer andsafer; the supporting steel plate is connected with the square sleeve, the joint area H-shaped steel girder section and the joint area square steel tube column section simultaneously through high-strength bolts, the bearing force of the girder and column joint is increased, thus stress is more reasonable, and the joint is firmer; and the welding section can be completed in a factory, on-site zero-welding is achieved, and thus the novel sleeve-type fabricated joint is suitable for fabricated connecting of the square steel tube column structure and the H-shaped steel girder structure.

Description

technical field [0001] The invention belongs to the field of building steel structures, and in particular relates to a beam-column assembled node in a steel structure and a construction method thereof. Background technique [0002] Steel structures are widely used for their light weight, high strength, high ductility, good seismic performance, fast construction speed, small component cross-section, and environmental protection. Square steel pipe columns and H-shaped steel beams are used as the main load-bearing components, and the joints connecting square steel pipe columns and H-shaped steel beams play an important role in structural force transmission and stability. The assembled rigid joints of the steel structure have sufficient rigidity, can keep the original angle between the intersecting members unchanged, and have sufficient ability to bear and transmit bending moments. [0003] At present, the connection nodes of square steel pipe columns and H-shaped steel beams i...
