Description

Technical Field

[0001] This utility model belongs to the field of building and bridge vibration reduction technology, and relates to a vertical vibration damping and noise reduction rubber bearing. Background Technology

[0002] Rubber seismic isolation bearings are widely used in various building constructions, highway bridges, and structural reinforcement. They employ a multi-layered composite of steel plates and rubber layers with excellent bonding, offering superior horizontal performance, damping coefficient, vertical performance, and vertical load-bearing capacity. However, with the increasing prevalence of rail transit and the growing number of subway-supersed buildings, the vehicle-induced vibrations from subway trains cause vertical vibrations in these buildings, impacting passenger comfort. While current rubber seismic isolation bearings effectively isolate horizontal vibrations from earthquakes, their ability to reduce and isolate vertical vibrations from subway traffic is limited. This limitation restricts the application and widespread adoption of seismic isolation bearings. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides a vertical vibration damping and noise reduction rubber support, which has vertical vibration damping capability, horizontal locking, and vibration reduction and noise reduction functions.

[0004] According to the technical solution of this utility model: a vertical vibration damping and noise reduction rubber support includes a rubber support body, the top surface of the rubber support body is connected to an upper connecting plate of the rubber support, and the bottom surface of the rubber support body is connected to a lower connecting plate of the rubber support; characterized in that: at least one hole is provided through the rubber support body.

[0005] The bottom surface of the upper connecting plate of the rubber support is fitted with an anti-shear pin corresponding to the hole, and the upper surface of the lower connecting plate of the rubber support is fitted with an anti-shear pin sleeve corresponding to the hole.

[0006] The upper anti-shear pin and the lower anti-shear pin sleeve are interlocked and assembled.

[0007] As a further improvement of this utility model, the upper anti-shear pin is fixedly connected to the upper connecting plate of the rubber support by an upper fixing bolt; the lower anti-shear pin sleeve is fixedly connected to the lower connecting plate of the rubber support by a lower fixing bolt.

[0008] As a further improvement of this utility model, the upper connecting plate of the rubber support has a through hole for connecting with the upper structure by bolts; the lower connecting plate of the rubber support has a through hole for connecting with the lower foundation by bolts.

[0009] As a further improvement of this utility model, both the upper connecting plate and the lower connecting plate of the rubber support are rectangular. The upper connecting plate of the rubber support has through holes on its two parallel sides, and the lower connecting plate of the rubber support has through holes on its two sides corresponding to the through holes of the upper connecting plate.

[0010] As a further improvement of this utility model, the rubber support body includes steel plates and rubber that are alternately stacked and vulcanized and bonded together.

[0011] The technical advantages of this utility model are as follows: the rubber support uses a simple and efficient structural design, and the main body is made of multiple layers of steel plates and multiple layers of rubber with excellent bonding. This structure has high vertical load-bearing capacity and vertical stability.

[0012] This rubber bearing can be adjusted to have different numbers of rubber and steel plate layers, and can be configured according to the actual on-site control frequency requirements to achieve extremely low vertical frequencies and meet the requirements for low-frequency vertical vibration damping.

[0013] The rubber bearing has an internal shear pin sleeve structure that locks the relative movement of the upper and lower foundations in the horizontal direction without affecting the vertical vibration damping displacement.

[0014] The rubber used in this bearing can effectively dissipate vibration energy, more effectively control low-frequency vibration, reduce vibration and noise in the foundation, greatly reduce the impact of vibration and noise on the superstructure, and has excellent aging performance, simple maintenance, and long service life.

[0015] The rubber bearing is simple and efficient to install, and is convenient for on-site construction. Attached Figure Description
