Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] A shock-isolation rubber support whose working performance parameters can be monitored and identified mainly includes a lead rubber shock-isolation device, a fiber grating strain sensor 3 and a pressure sensor 5 . Such as figure 1 , 2 As shown in and 3, the fiber grating strain sensor 3 is installed vertically inside the lead rubber shock-isolation device to monitor the shear deformation in the horizontal direction, and the pressure sensor 5 is arranged at the bottom of the lead-core rubber shock-isolation device to monitor the vertical change to pressure.

[0025] The lead rubber shock-isolating device includes an upper top plate 1, a lower bottom plate 7, laminated rubber 2, steel plates 4 and lead cores 6, and the steel plates 4 and laminated rubber 2 are alternately laminated to form a shock-isolation layer and are arranged on the lower bottom plate 7 An ...

Abstract

The invention discloses a shock insulation rubber support with working property parameters capable of being monitored and recognized. The support comprises a lead core rubber shock insulation device, a fiber bragg grating strain sensor and a pressure sensor, wherein the fiber bragg grating strain sensor is vertically installed in the lead core rubber shock insulation device and is used for monitoring the shear deformation in the horizontal direction; and the pressure sensor is arranged at the bottom of the lead core rubber shock insulation device and is used for monitoring the change of pressure in the vertical direction. According to the invention, relevant property parameters of the support can be automatically monitored, and the support has strong practicability and wide application prospects.

Description

technical field [0001] The invention relates to the field of seismic isolation technology, in particular to the technical field of combining sensor monitoring technology with seismic isolation technology. Background technique [0002] my country is located in the circum-Pacific seismic belt and the Eurasian seismic belt, and is a country with frequent earthquakes. Earthquakes can not only cause structural damage, but also induce various other secondary geological disasters, such as mudslides and landslides, which seriously threaten the safety of human life and property. In particular, the traffic interruption caused by the earthquake damage to the bridge structure has seriously hindered the post-disaster rescue work. In recent years, the seismic isolation and energy consumption technologies of bridge structures have developed rapidly. Engineers and technicians have weakened the seismic response of bridge structures and enhanced the seismic capacity of bridge structures from...
