Abstract

The invention relates to the technical field of construction framework members, and discloses a fabricated self-recovery round steel pipe concrete combination node. The node comprises a round steel pipe column and H-shaped steel beams, steel bars penetrate through the round steel pipe column, and the round steel pipe column comprises an upper segment steel pipe column, a center inserting column and a lower segment steel pipe column. The upper segment steel pipe column and the center inserting column are connected through a lower sleeve connecting part; the H-shaped steel beams are connected with the round steel pipe column through an upper sleeve connecting part and a lower sleeve connecting part. All members of the bode can be processed and finished in a factory and are connected throughbolts in site, complete fabricated construction is achieved, possible quality problems caused by field welding are avoided, construction progress is accelerated, and labor productivity is improved; bythe design of the node, the earthquake fortification purposes of no damage in a small earthquake, rapid recovery of deformation after a middle earthquake, and accurate dismantle and rapid replacementafter a large earthquake are achieved.

Description

technical field [0001] The invention relates to the technical field of building structural components, in particular to an assembled self-restoring circular steel pipe concrete composite node. Background technique [0002] Steel structural components form a structural system by connecting nodes, and the choice of node form has a direct impact on structural integrity, reliability, construction period, and the design and construction of auxiliary components. The connection between beam and column of frame structure can be divided into rigid connection, flexible connection and semi-rigid connection according to the difference of rotational stiffness. [0003] At present, rigid connection design is the most widely used. Traditional frame beam-column rigid connection can be divided into three types: fully welded connection, bolt-weld hybrid connection and bolt connection. The study found that the first two connection forms are prone to brittle failure due to the quality of the b...
