Description

The present invention belongs to the technical field of building vibration damping, and specifically relates to a bolt direct pressure type rubber vibration damping damper (SAI vibration damping damper).

The earthquake caused many disasters for humankind, and the Wenchuan and Tangshan earthquakes in China, which people are familiar with, caused many casualties and economic losses. The threat of earthquakes to humankind is so great that earthquakes can occur wherever people are and endanger their lives.

Building engineers have proposed three structures for buildings: seismic structures, seismic isolation structures, and vibration control structures, in order to reduce earthquake damage to buildings.

(1) Seismic structures: Seismic structures are structures that resist the inertial forces caused by earthquakes due to the bearing capacity of the building and ensure the safety of the building. One of the drawbacks of seismic structures is that some buildings may be damaged or collapsed due to violent shaking during a large earthquake, and safety and post-earthquake maintenance are also issues.

(2) Seismic isolation structure: The seismic isolation structure uses seismic isolation measures and seismic isolation equipment to weaken and reduce the effects of earthquakes, thus significantly reducing the effects of earthquakes on the structure. The disadvantage of the seismic isolation structure is that it is necessary to add a seismic isolation layer, which leads to a significant increase in construction costs.

(3) Vibration control structure: In building vibration control (energy dissipation vibration control technology of the structure), an energy absorbing device is placed in a specific place (for example, brace) of the structure, and the structure is made into a structure by an earthquake due to frictional force and deformation. It is a structure that absorbs the generated energy and reduces the seismic force energy generated in the main body structure. By doing so, it avoids the destruction and collapse of the structure and achieves the purpose of damping control. Existing vibration damping devices mainly include (1) hydraulic dampers for vibration damping, (2) unbonded braces (vibration damping tension braces), and (3) bolt indirect pressure damping dampers (cantilever pressurization method). ..

Currently, the damping device that is relatively widely used in China is the hydraulic damping damper, and the disadvantage of the hydraulic damping damper is that the price is relatively high, so the construction cost may be high, countries such as Japan. In many cases, unbonded braces are used, and the drawback is that the steel core material is plastically deformed after the earthquake and loses its elasticity. Therefore, the steel core material must be replaced. This will lead to a significant increase in maintenance costs after the earthquake. In addition, the price of the unbonded brace itself is relatively high, so the construction cost is also a problem. In addition, the disadvantage of the bolt indirect pressurization damping damper is that the bolt indirectly pressurizes through the steel plate cantilever, so the frictional force that can be generated is relatively small, and it is generally applied to ultra-small buildings, but it is medium and large. The application of this to buildings is questionable.

In view of the problems mentioned in the background art above, it is an object of the present invention to provide a bolt direct pressure type rubber damping damper. In order to achieve the above technical object, the present invention adopts the following technical proposals.
