Abstract

This invention is in structure tremble isolation and vibration control field, consists of upper connective tabulae, lower connective tabulae, rubber tile, steel plate, protective layer. Its characteristics are: steel plate and rubber tile are at superposition position; there is a hole in central part of steel plate; rubber tile has zonal shape; there is space in between steel plate and rubber tile; there is a liquid injection hole in the central part of uper connective tabulae; liquid injection hole is connected with through hole formed in the middle of abutment, and sealed with sealing thread plug; electricorheological fluids is full of the space formed in between steel plate and rubber tile; leadwire from end of steel plate is used to conenct with control divices providing control signals. In this invention, horizontal stiffness and damping characteristic sof abutment can be adjusted real time, this invention has strong pressurization capability, good deformability, good resilience capability, good energy consumption ability, and is applicable for the applications, where the existing superposition rubber abutment is used.

Description

technical field

[0001] The invention relates to a laminated rubber bearing for earthquake isolation, which belongs to the field of structure isolation control and vibration control, and is mainly used for base isolation of buildings such as houses and bridges. Background technique

[0002] Laminated rubber bearing isolation is a relatively mature engineering isolation technology. Through the isolation device, the upper structure of the building is "isolated" from the foundation, and the dynamic characteristics of the upper structure are changed, which can greatly reduce the impact of earthquakes on the upper structure. In order to achieve the shock absorption effect of "overcoming rigidity with softness". The laminated rubber bearing is made of rubber layer and steel plate layered and bonded by high temperature vulcanization. When the rubber bearing bears the vertical load, the lateral deformation of the rubber layer is restrained, so that the rubber bearing has a large ver...
