Abstract

The invention provides a plug-in type modular steel structure seismic mitigation and absorption connecting joint. An upper side cross-shaped plug-in and a lower side cross-shaped plug-in are perpendicularly connected with an upper side sealing plate and a lower side sealing plate of a lead core rubber seismic isolation support correspondingly; the side walls of an upper steel pipe module column and a lower steel pipe module column are connected with H-shaped steel module beams correspondingly; the end of the upper steel pipe module column and the end of the lower steel pipe module column are arranged outside the upper side cross-shaped plug-in and the lower side cross-shaped plug-in a sleeving mode correspondingly; the upper side cross-shaped plug-in and the lower side cross-shaped plug-in are the same in structure and each comprise a cross-shaped component and a connecting plate; the cross section of each cross-shaped component is in a cross shape; the end of each edge of each cross-shaped component is perpendicularly connected with the corresponding connecting plate; a preset distance is reserved between the edges of every two adjacent connecting plates; the cross-shaped components and the connecting plates of the upper side cross-shaped plug-in and the lower side cross-shaped plug-in are connected with the upper side sealing plate and the lower side sealing plate correspondingly; and the side walls of the upper steel pipe module column and the lower steel pipe module column are connected with the connecting plates of the upper side cross-shaped plug-in and the lower side cross-shaped plug-in through bolts correspondingly. The plug-in type modular steel structure seismic mitigation and absorption connecting joint is simple in structure, high in prefabrication rate and capable of being rapidly installed without too large operation space and has good seismic resistance.

Description

technical field [0001] The invention relates to the technical field of construction engineering, and relates to an anti-seismic connection node structure between modular steel structure prefabricated cabins and box-type steel structure modules, in particular to a plug-in modular steel structure anti-seismic connection node. Background technique [0002] The new steel structure building has the advantages of high rigidity, light weight, short construction period, energy saving and environmental protection. With the vigorous development of prefabricated modular steel structures, nodes are the core of steel structure modular building design, and the reliability of nodes directly affects the safety of the overall module. Although scholars at home and abroad have proposed the joints of steel structure box buildings or container buildings, the existing joint forms require a large operating space and a long connection time, and they are all biased towards the connection problem wit...
