Laminated rubber shock insulation structure on upper portion of house and construction process

Abstract

The invention relates to the technical field of house shock insulation structure construction, and provides a laminated rubber shock insulation structure on the upper portion of a house aiming at the situation that a rubber support is prone to being damaged due to the fact that transverse building generated by a traditional earthquake directly acts on the rubber support. The laminated rubber shock insulation structure comprises a limiting cylinder pre-embedded in a foundation and an upper pier column arranged below a house superstructure, a lower pier column is arranged in the limiting cylinder, the lower pier column is opposite to the upper pier column, a rubber support is further arranged between the upper pier column and the lower pier column, the top end of the rubber support is connected with the upper pier column, and the bottom end of the rubber support is connected with the lower pier column; a gap is reserved between the periphery of the lower pier column and the inner periphery of the limiting cylinder, and a plurality of elastic pieces are further arranged on the periphery of the lower pier column. The laminated rubber shock insulation structure has the effect of reducing direct action of transverse shear force on the rubber support.

Description

technical field [0001] The present application relates to the technical field of building earthquake-isolation structures, in particular to a laminated rubber earthquake-isolation structure on the upper part of a house and a construction process. Background technique [0002] In order to reduce the damage to houses caused by earthquakes, a seismic isolation layer is usually installed between the building and the foundation. The seismic isolation layer in the related art includes a lower pier set on the foundation and an upper pier set on the upper structure of the house, and laminated rubber bearings are installed between the upper pier and the lower pier. [0003] The laminated rubber bearing is composed of multi-layer steel plates and rubber plates, and its upper and lower parts are respectively provided with an upper flange and a lower flange. The column is connected with the lower pier column so that the upper structure of the house can form a soft connection with the g...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the applicant believes that there are the following defects: the transverse shear force generated during the earthquake usually directly acts on the rubber bearing through the lower pier column, and the earthquake frequency When the vibration occurs, the transverse shear force directly acts on the rubber bearing for a long time, which will easily lead to accelerated aging of the rubber bearing, and eventually lead to failure and damage of the rubber bearing, and the corresponding shock absorption effect cannot be exerted.
