Combined column foot capable of being repaired in situ
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.
