Method for assembling laminated steel-lead support adopting lead plates formed by in-situ pouring and cooling

Abstract

The invention relates to a method for assembling a laminated steel-lead support adopting lead plates formed by in-situ pouring and cooling, and belongs to the technical field of seismic isolation. The laminated steel-lead support mainly comprises an upper cover plate, a lower cover plate, lead plates and thin steel plates, wherein the lead plates and the thin steel plates are stacked between the upper cover plate and the lower cover plate alternately. When the laminated steel-lead support is assembled, heated lead is poured in gaps among the thin steel plates, the upper cover plate and the lower cover plate after the thin steel plates are inserted in three enclosing plates through an assembly jig, and the cooled lead plates are correspondingly inlaid in first grooves and second grooves of the upper cover plate, the lower cover plate and the thin steel plates. In the method, the steel plates in the laminated lead plates provide a hooping effect for the lead plates so that the radial expansive deformation of the lead plates caused when the lead plates are pressed is limited, and meanwhile by virtue of the excellent plastic property of lead, high energy consumption is provided at the time of horizontal deformation. Horizontal large deformation can be realized easily by increasing the horizontal size and quantity of the laminated lead plates. After being assembled, the support has large vertical bearing capacity and vertical rigidity, and has stable energy consumption capacity and large deformation capacity in the horizontal direction.

Description

technical field [0001] The invention relates to a method for assembling a support, in particular to a method for assembling a laminated steel-lead support that adopts on-site pouring and cooling to form a lead plate, and belongs to the field of shock isolation technology. Background technique [0002] Seismic isolation technology is to add an appropriate buffer between the bottom of the building and the foundation or between the supporting structure and the upper structure, so that the acceleration response of the building after being subjected to the earthquake wave is greatly weakened, and the displacement of the building is mainly controlled by the seismic isolation system. Bear, so that the deformation of the building in the earthquake is very small, in order to achieve the purpose of protection. The vibration isolation components include laminated rubber bearings, lead core rubber bearings, sand cushions, graphite cushions, friction sliding bearings, and parallel compos...
