Description

Technical Field

[0001] The utility model relates to the technical field of viscous damping vibration absorbers, in particular to a floating floor viscous damping vibration absorber. Background Art

[0002] Floating floor is a building technology used for vibration isolation and noise reduction. Its main function is to isolate solid sound and airborne sound between upper and lower floors by laying elastic pads or spring-supported paving on the floor. Floating floor consists of multiple components, including elastic support members (vibration damping pads), edge rubber pads, sound insulation cotton, building formwork, waterproof membrane and reinforced concrete floor. Viscous damping shock absorber is a device that uses the movement of pistons in viscous damping fluid to generate viscous damping to dissipate energy. It is widely used in building structures to reduce vibration and noise. This damper has good stability and efficient energy dissipation capacity, and is particularly suitable for vibration isolation systems that require high-precision control. Combining the application of floating floor and viscous damping shock absorber can effectively improve the vibration isolation performance of buildings. Specifically, floating floor isolates the equipment from the floor by adding a layer of elastic pad on the floor, thereby preventing the vibration generated by the equipment from being directly transmitted to the floor. The viscous damping shock absorber can dissipate energy during the movement of the piston through the viscous damping fluid inside it, further reducing the vibration transmission.

[0003] At present, when using the traditional floating floor viscous damping vibration isolator, a waterproof membrane is first laid on the floor during construction. After the system load distribution is calculated, the device is arranged on the waterproof membrane according to the load distribution, and then the building steel bars woven into a mesh are erected on the device, and the concrete floating floor is poured. After the concrete floating floor is solidified, the device reduces vibration and noise for the building. However, when the device vibrates, the parts inside the device will rub against each other and produce abnormal sounds, making noise, causing inconvenience to users. Utility Model Content
