Abstract

The invention discloses a mounting structure and a construction method of an isolation bearing in existing building base isolation reinforcement. The mounting structure of the isolation bearing comprises an upper pier, an isolation bearing body and a lower pier. The isolation bearing body is arranged between the upper pier and the lower pier. The upper pier is connected with the isolation bearingbody through an upper portion connection measure, and the lower pier is connected with the isolation bearing body through a lower portion connection measure. The upper portion connection measure and the lower portion connection measure both comprise pre-buried plates, anchoring ribs, bolt locking parts, grouting material mixtures, bolt assemblies and isolation bearing connection plates. The mounting structure and the construction method overcome the defect that a traditional pre-buried sleeve connection mode cannot adapt to isolation reinforcement construction, the bolt locking parts and the bolt assemblies are adopted to solve the problem of precise positioning of bolt holes, the isolation bearing is protected effectively, and the mounting and connection levels of the isolation bearing are improved.

Description

technical field [0001] The invention belongs to the technical field of seismic isolation of building structures, and in particular relates to an installation structure and construction of a seismic isolation support, which can be used when the seismic isolation support is used in the seismic reinforcement and structural engineering of existing buildings in earthquake zones. Background technique [0002] In new buildings, the connection between the seismic isolation support and the column is generally adopted by welding the embedded sleeve on the back of the embedded plate of the column, and the connecting plate of the support and the embedded plate are connected by bolts. In the seismic isolation reinforcement project, the underpinning of the frame column generally adopts the peripheral bracket. Firstly, the column is cut off, and then the lower pier is washed and the isolation support is installed following the practice of new buildings, and then the upper pier is poured. T...
