Rigid connection joint for spatial oblique insertion of H-shaped steel structure component and round steel pipe column

Abstract

The invention relates to a rigid connection joint for spatial oblique insertion of an H-shaped steel structure component and a round steel pipe column. The connection joint comprises the round steel pipe column, H-shaped steel beams, two outer connection ring plates, adaptation steel pipes and seal head steel plates. The round steel pipe column forms spatial oblique insertion with the H-shaped steel beams, the round steel pipe column is sleeved with the outer connection ring plates and is welded to the outer connection ring plates, upper flanges and lower flanges of the H-shaped steel beams are welded to the two outer connection ring plates respectively, the adaption steel pipes are welded to the round steel pipe column, H-shaped steel beam webs are inserted into grooves formed in the vertical direction and welded at the positions where the grooves are formed, and the seal head steel plates are located at the ends of the adaption steel pipes and welded to the adaption steel pipes and the upper flanges, the lower flanges and the webs of the H-shaped steel beams. The rigid connection joint has the advantages of achieving the rigid connection of the H-shaped steel beams and the round steel pipe column which are obliquely interested and being simple in construction form and reliable in force transmission.

Description

technical field [0001] The invention relates to the technical field of building steel structure nodes, in particular to a space oblique rigid connection node between an H-shaped steel structure member and a round steel column column. Background technique [0002] At present, in building structures, due to its good bending resistance, H-shaped steel members are usually used as horizontal bending members to withstand the vertical bending moment generated by vertical loads, while round steel pipes are usually used due to their good compression performance. As a vertical load-bearing member. When the circular steel pipe column and the H-shaped steel beam are an orthogonal frame system, that is, when the circular steel pipe is vertically arranged and perpendicular to the horizontal H-shape, the two are easy to connect. In the existing technology, the H-shaped steel web and wing The flange is directly welded to the round steel pipe for connection. [0003] In recent years, in or...

Problems solved by technology

[0003] In recent years, in order to adapt to the increasingly complex and diverse architectural forms and functions, a space oblique frame system has emerged. However, the traditional method of direct welding of H-shaped steel and round steel pipes is only suitable for the axis of the round steel pipe and the web of the H-shaped steel. Orthogonal or plane oblique frame system in the plane case, when the circular steel pipe column and the H-shaped steel beam are obliquely intersected in...
