Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0032] Such as figure 1 and figure 2 As shown, the in-situ repairable composite column foot provided by this embodiment includes a steel drum 20 fixedly installed at the bottom of the reinforced concrete column 10, a damper 30 connected to the outer surface of the steel drum 20 at one end, and another connection with the damper 30. The connecting plate 40 is connected at one end, and the connecting plate 40 is fixedly installed on the ground beam 50 corresponding to the reinforced concrete column 10 .

[0033] The reinforced concrete column 10 can be a conventional column, and in this embodiment, the reinforced concrete column 10 is a square column. The shape of the steel drum 20 matches the shape of the reinforced concrete column 10 and is also square. The steel drum 20 includes four side steel plates 21 corresponding to the four sides of t...

Abstract

The invention provides a combined column foot capable of being repaired in situ, which is good in anti-earthquake performance and capable of being rapidly repaired after an earthquake. The combined column foot comprises a steel plate bucket, a damper with one end connected to the outer side surface of the steel plate bucket, and a connection plate connected with the other end of the damper, wherein the connection plate is fixedly installed on a ground beam corresponding to a reinforced concrete column, the damper is provided with a detachable flexible steel plate, and the flexible steel plate is vertically placed. By arranging the damper (the flexible steel plate), in case of a small earthquake, the flexible steel plate used as an energy-consuming plate of the damper is capable of generating a concentrated deformation to absorb most of earthquake energy due to a relatively good plasticity; in case of a strong earthquake, the flexible steel plate generates a shear yield to consume the earthquake energy, thus greatly protecting the reinforced concrete column from being damaged or collapsing and further achieving good anti-earthquake performance; meanwhile, because the flexible steel plate is detachable, the damaged flexible steel plate can be taken off and replaced by a complete flexible steel plate after the strong earthquake, thus realizing post-earthquake rapid repair.

Description

technical field [0001] The invention relates to an anti-seismic structure of a concrete member, in particular to a composite column base which can be repaired in situ after an earthquake. Background technique [0002] The intelligentization and sustainability of urban development pose new requirements and challenges to the industrialization of buildings and seismic structures of engineering structures. Among them, the rapid repair of structural earthquake damage and the rapid recovery of building functions are the basic requirements and important aspects of "recoverable functional cities". research direction. Recoverable performance structures generally refer to building structures that can recover their performance without repair or moderate repair after the structure encounters an earthquake. The research and development, promotion and application of restorable performance structures can not only significantly reduce direct earthquake damage losses, but also significantly ...
