Inner sleeve type unilateral bolt connecting joint of steel tube column and H-shaped steel girder

Abstract

The invention relates to an inner sleeve type unilateral bolt connecting joint of a steel tube column and an H-shaped steel girder which is simple in structure, good in performance and reliable in joint quality. The inner sleeve type unilateral bolt connecting joint comprises the steel tube column, the H-shaped steel girder, a steel sleeve, a transverse partition plate, externally-extended end plates and high-strength bolts, wherein the steel sleeve is arranged coaxially in the steel tube column; the transverse partition plate is fixed to a flange of the H-shaped steel girder in the steel sleeve in a coplanar mode; the externally-extended end plates are welded at the ends of the H-shaped steel girder; and the high-strength bolts penetrate through the externally-extended end plates. Tapping bolt holes are formed in the steel sleeve and matched with the high-strength bolts. A plurality of bolt holes are formed in a pair mode in the externally-extended end plates and the steel tube column in the axial direction of the steel tube column. At least two positioning circular holes are formed in a connecting wall plate and an opposite wall plate correspondingly by the steel tube column in the axial direction of the steel tube column. The bolt holes and the tapping bolt holes on the same side are formed oppositely. The positioning circular holes on the same side are formed oppositely. The high-strength bolts sequentially penetrate through the bolt holes in the externally-extended end plates and the bolt holes in the steel tube column and are connected with the tapping bolt holes corresponding to the steel sleeve, and are tightened and fixed according to the designed pretension force of the high-strength bolts.

Description

technical field [0001] The invention belongs to the technical field of civil engineering and mechanical assembly, and relates to the construction technology of an assembled steel structure, in particular to an inner sleeve-type unilateral bolt connection node between a steel pipe column and an H-shaped steel beam. Background technique [0002] Steel pipe columns have high torsional rigidity and good stability, and are often connected with H-shaped steel beams to form a steel frame. Due to the closed cross-section of steel pipes, high-strength bolts cannot be directly applied to the connection nodes. H-shaped steel beams and steel pipe columns are often connected by means of transition pieces such as short outrigger beams, ring ribs, and partitions. The amount of on-site welding is large, and the quality of the joints is not easy to guarantee, and the degree of assembly is low. [0003] In order to avoid a large number of welding on site and improve the degree of assembly, u...
