Description

Technical Field

[0001] This utility model relates to the field of vibration isolation rubber technology, specifically a vibration isolation rubber bearing with force measurement function. Background Technology

[0002] Seismic isolation rubber is a type of seismic isolation material used in buildings, bridges, and other structures. It is usually made of multiple layers of rubber sheets and steel sheets that are alternately laminated and vulcanized. The rubber provides elastic deformation capacity, while the steel sheets enhance the overall stiffness. It can absorb seismic energy through its own shear deformation, reducing the transmission of vibrations in the structure during an earthquake.

[0003] Seismic isolation rubber bearings are the core seismic isolation devices for structures such as buildings and bridges. They are made of multiple layers of rubber sheets and thin steel plates that are alternately laminated and vulcanized. The rubber layers provide elastic deformation capacity, while the steel plates enhance load-bearing stiffness. They can absorb seismic energy through shear deformation, significantly reducing the vibration transmission of earthquakes to the superstructure. They have both vertical load-bearing and horizontal seismic isolation functions, thus improving the seismic safety of the structure.

[0004] Existing seismic isolation rubber bearings have the following problems: they lack force measurement functionality. Force measurement is used to test the bearing capacity of the seismic isolation rubber bearing to ensure that the bearing can stably support the weight of the superstructure. Simultaneously, it is necessary to evaluate its deformation performance and mechanical response under different loads. This usually requires the use of built-in force sensors, which makes disassembly inconvenient and hinders maintenance. To address these issues, a seismic isolation rubber bearing with force measurement functionality is proposed. Utility Model Content

[0007] By adopting the above technical solution, the top plate is pulled by the pull bar to move it to the appropriate position along the slide. The pressure sensor is then inserted along the inner wall of the third slide groove. The pull bar is released, and under the elastic force of the spring, the top plate can be pushed into the groove of the pressure sensor, thus completing the installation of the top plate.

[0015] By adopting the above technical solution, the rubber sheet is protected by an outer layer.

[0016] As a further description of the above technical solution: a lead core is fixedly connected to the top center of the base plate, the top of the lead core is fixedly connected to the top plate, and the outer ring of the lead core penetrates and is fixedly connected to the rubber plate.

[0017] By adopting the above technical solution, the lead core makes the rubber sheet more stable.

[0018] As a further description of the above technical solution: a first sliding groove is provided on one side of each of the four sides of the base plate, and the inner wall of the first sliding groove is slidably connected to the pull strip.

The pull bar is released, and under the elastic force of the spring, the top plate can be pushed into the groove of the pressure sensor, thus completing the installation of the top plate. The pressure sensor can be disassembled according to the above steps.

[0024] This utility model provides a seismic isolation rubber bearing with force measurement function. It can isolate vibration through rubber plate and lead core. At this time, as the top plate moves downward, the rotating plate rotates along the collar and slider, which allows the slider to pull the damper and move along the second slide groove. Through the deformation of the damper, vibration isolation can be performed again, and the vibration isolation effect can be improved. Attached Figure Description
