An h-shaped steel structure member and a circular steel column space oblique rigid joint connection node

Abstract

The invention relates to a space oblique rigid connection joint between an H-shaped steel structure member and a circular steel pipe column, including a circular steel pipe column, an H-shaped steel beam, two circumscribed ring plates, a conversion steel pipe and a head plate. The space of the H-shaped steel beam is oblique, the outer ring plate is set on the circular steel pipe column and welded with the circular steel pipe column, the upper and lower flanges of the H-shaped steel beam are respectively welded to the two outer ring plates, so The conversion steel pipe is welded to the round steel pipe column, and slotted in the vertical direction to insert into the web of the H-shaped steel beam and welded at the slot. The head steel plate is located at the end of the conversion steel pipe, and is connected to the The conversion steel pipes are welded to the upper and lower flanges and webs of the H-shaped steel beams. The invention has the advantages of realizing the rigid connection between oblique H-shaped steel beams and round steel pipe columns, and has simple structure and reliable force transmission.

Description

technical field [0001] The invention relates to the technical field of building steel structure nodes, in particular to an H-shaped steel structure member and a space oblique rigid connection connection of a circular steel tube column. Background technique [0002] At present, in building structures, H-section steel members are usually used as horizontal bending members to withstand the vertical bending moment generated by vertical loads due to their good flexural performance, while round steel pipes are usually used due to their good compressive performance. as a vertical load-bearing member. When the round steel tube column and the H-shaped steel beam are orthogonal frame systems, that is, when the round steel tube is arranged vertically and perpendicular to the horizontal H-shape, the two are easy to connect. The edge is welded directly to the round steel pipe for connection. [0003] In recent years, in order to adapt to the increasingly complex and diverse architectur...

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 space, that is, the axis of the circular steel pipe column and the H-shaped steel web are not in the same plane, the existing direct welding method cannot combine the two The two are effectively connected together to realize the rigid connection structure to transmit the internal force of the member, especially when the angle between the two is large, the web and flange of the H-shaped steel are beyond the contour range of the round steel pipe, and the traditional structure is not feasible.
