Description

Technical Field

[0001] The utility model relates to the technical field of building components, in particular to a metal seismic isolation support with multiple seismic isolation functions and adjustable fire protection and shock absorption. Background Art

[0002] Existing earthquake damage data show that earthquakes not only damage structural components, but also non-structural components. Among the relevant technologies, the use of seismic isolation technology is an effective way to improve the seismic resistance of buildings and meet the requirements of structural performance-based design. Among seismic isolation technologies, seismic isolation bearings are the most widely used.

[0003] Seismic isolation bearings are usually made of flexible materials such as rubber, and have the characteristics of small horizontal stiffness and large vertical stiffness. By arranging seismic isolation bearings between the building foundation or the lower structure and the upper structure, the natural vibration period of the overall structure can be extended, and the seismic effects transmitted to the upper structure can be effectively reduced, thereby reducing the seismic response and damage of the upper structure, so as to ensure that the building function is not affected by earthquake disasters as much as possible. In the prior art, seismic isolation bearings are used to consume the horizontal vibration energy of the earthquake and the vertical vibration energy brought by the environment, but the shock absorbing capacity of this seismic isolation device is limited. When a large earthquake occurs, it is difficult to completely dissipate the energy of the horizontal vibration, which makes the building have a greater safety hazard. Utility Model Content

Two movable seats 431 are symmetrically provided, and a connecting plate 432 is installed on the two movable seats 431. The electromagnetic shock absorber 433 is installed between the two connecting plates 432. The electric control box 434 is installed on the electromagnetic shock absorber 433, and the electric control box 434 is connected to an external control power supply.

[0043] In this embodiment, the electrical control box 434 can send a signal through the control unit installed inside, so that the electromagnetic coil 16 generates a voltage magnetic field, thereby changing the arrangement of the electromagnetic fluid, so that the seismic isolation bearing can perform corresponding processing for different vibration frequencies and vibration amplitudes, and has adjustability, which increases practicality and flexibility.

[0044] In this embodiment, the electromagnetic shock absorber 433 includes a push rod 11, a cylinder body 12, a piston 13, a spring 14, an outer tube 15, and an electromagnetic coil 16. One end of the push rod 11 is connected to the connecting plate 432, and the cylinder body 12 is slidably fitted on the push rod 11.

[0047] Working principle: When the building body vibrates, the vertical seismic isolation tube 31 and the rubber seismic isolation tube 41 installed on the seismic isolation support can isolate the vertical vibration force exerted on the building, reduce the displacement and deformation of the building structure, and at the same time, due to the vibration of the building, the connecting rod 323 and the rotating rod 324 on the seismic isolation part 3 will rotate in relative directions, thereby squeezing the buffer airbag 326 between the connecting rod 323 and the rotating rod 324, so that the friction between them can buffer and consume the horizontal and vertical energy of the building, thereby reducing the transmission of the lower energy to the upper part and reducing the deformation of the building structure. In addition, the energy dissipation device 32 is distributed around the vertical seismic isolation tube 31, which can increase the stability of the seismic isolation part 3. At the same time, a shock absorbing part 4 is provided above the seismic isolation part 3. The spring damper 422 and the electromagnetic shock absorber 43 are provided. With the help of the spring damper 422, it has the advantages of composite vibration isolation and noise reduction, low natural frequency and good vibration isolation effect. It can damp the vibration energy transmitted by the lower part of the isolation support, and then send a pulse signal through the control unit of the electrical control box 434, so that the electromagnetic coil 16 on the electromagnetic shock absorber 433 will generate voltage, thereby forming a magnetic field, which can change the arrangement of the electromagnetic fluid in the cylinder body 12, and then hinder the flow effect of the electromagnetic fluid in the cylinder body 12, so as to improve the damping coefficient of the spring 14, so that the isolation support can control the voltage magnetic field of the electromagnetic coil 16 according to different vibration frequencies and vibration amplitudes, and perform corresponding shock absorption. It has adjustability, increases practicality and flexibility, and improves the stability of the building during earthquakes.
