Connecting structure of steel pipe column and steel beam

Abstract

The invention discloses a connecting structure of a steel pipe column and a steel beam. A connecting component comprises at least one connecting plate, one side of the connecting plate is used for being attached to the steel pipe column, the other side is used for being connected with an end plate of the steel beam, the end plate is provided with a through hole, the connecting plate is provided with a first threaded hole, the first threaded hole is matched with a unilateral bolt, the unilateral bolt sequentially penetrates through the end plate, the connecting component and the steel pipe column wall, the threaded part of the unilateral bolt is sequentially matched with the first threaded hole and a second threaded hole pre-formed in the steel pipe column, and the connecting component is matched with the unilateral bolt to enable the steel beam to be connected with the steel pipe column and to be fixed. The connecting component plays a role of connection and is also an enhancing component at the same time, through the connecting component, the anchoring length of the bolt, the thickness of the steel pipe column wall and the effective thickness of the outer side of the beam end plate are increased, the anti-deformability of the end plate outside the beam and the steel pipe column is improved, and the anchoring length of the bolt is increased.

Description

technical field [0001] This application relates to the field of steel structure joints, specifically the connection structure of steel pipe columns and steel beams. Background technique [0002] At present, there are three main ways to connect steel structures: bolted connection, welded connection, and bolt-welded hybrid connection. Among them, the welded connection has the largest strength and rigidity, but its construction is greatly affected by the weather and site environment, and the technical requirements for welding workers are relatively high, and the construction speed is slow, and the construction quality is not easy to guarantee; while the bolted connection is fast and simple to install, mechanically The advantages of stable performance, high degree of assembly, and convenient inspection and replacement have become a more ideal connection form. [0003] The inventors found that the pipe column has better load-bearing performance than the steel pipe column with op...

Problems solved by technology

[0006] The purpose of this application is to provide a connection structure between a steel pipe column and a steel beam in view of the defects in the prior art. By setting the connecting member as an intermediate piece between the steel pipe column and the steel beam, and matching the preset threaded holes on the steel pipe column, the problem is solved. It solves the problem that the closed-section column joints in the steel structure are difficult to be connected by bolts. The relative wall thickness of the steel pipe column is increased by the connecting member, so as to meet the needs of bolt anchorage. It is fixed by screw fit connection, which avoids the welding process on the construction site and realizes Fully assembled construction
