Description

Technical Field

[0001] The present invention relates to the technical field of TOD vibration isolation, in particular to a tensile thick-layered rubber vibration isolation device for a TOD upper cover building. Background Art

[0002] The TOD model is a public transportation-oriented development. It is a non-motorized planning and design method that maximizes the use of public transportation when planning a residential or commercial area. The TOD model not only alleviates the problem of traffic congestion, but the commercial value of the buildings above it is also enormous.

[0003] However, buildings above the subway will be subject to environmental vibrations caused by the subway during its operation, which is unbearable for buildings along the subway line with huge commercial value. Long-term repeated subway vibrations with significantly high frequencies may have some impact on structural safety, especially structural use functions, causing cracks in structural floors or walls, etc. Such vibrations may also affect the human comfort inside the building and cause potential adverse effects on residents' rest and life.

[0004] Therefore, the development of tensile vibration isolation devices for TOD mode building structures has become a hot spot and difficulty in the current vibration control field. How to develop a tensile vibration isolator that can not only effectively isolate environmental vibrations, but also take into account the normal use of building functions and the safety of the superstructure is a difficult problem in the current structural vibration control field. In recent years, vibration isolation devices for TOD mode building structures have achieved certain research results, but these vibration isolation devices still have the following problems:

[0005] 1. Although the vibration isolators currently used in actual projects are effective, they are relatively large or high in size. The piers of the building must be adjusted accordingly to accommodate the size of the vibration isolators. At the same time, the vibration isolators also have stability risks, which increases costs and construction difficulties. In particular, the building function is greatly reduced, and the superstructure also has safety hazards.

[0006] 2. Ordinary laminated rubber bearings can usually only be used to isolate earthquakes and reduce horizontal loads. They are incapable of absorbing vertical vibrations caused by rail transit vehicles.

[0007] 3. Laminated rubber bearings have obvious effects on vertical vibrations, but their structure is not tensile, which endangers the safety of the upper structure, especially for high-rise buildings.

[0008] 4. Although vibration isolation bearings can reduce the impact of rail transit vehicle-induced vibration, they may amplify the structural response and bring adverse effects when ground vibration occurs. Summary of the invention
