Description

Vertical shock insulation device
Technical Field
The invention relates to the technical field of building vibration isolation, in particular to a vertical vibration isolation device.
Background
The base vibration isolation technology forms a vibration isolation layer by arranging a vibration isolation device between the bottom of the structure and the base, and prolongs the self-vibration period of the structure so as to reduce the response of the structure under the action of earthquake. A large number of buildings adopting the basic vibration isolation technology have been subjected to the test of earthquakes so far, and the effectiveness of the vibration isolation technology is proved. However, the currently widely used base seismic isolation technique only has an effective seismic isolation effect on horizontal seismic components, has little seismic isolation effect on vertical seismic, and sometimes amplifies vertical seismic response. However, a series of strong shock recordings show that there is a strong vertical shock near the fault, with some vertical acceleration peaks being close to or even much larger than the horizontal acceleration peaks. Therefore, effective vertical shock insulation is particularly important for buildings in high intensity areas, particularly near fault areas.
Aiming at the problems, many students at home and abroad conduct intensive researches on vertical vibration isolation technology, and the existing vertical vibration isolation technology is mainly divided into four types: 1) Thick layer rubber; 2) Coil springs and belleville springs; 3) Air springs; 4) Vertical TMD systems. The students develop different types of three-dimensional shock-insulation supports by carrying out series connection, parallel connection combination or inclined arrangement of the rubber supports on the shock-insulation supports and the conventional laminated rubber supports. The thick-layer rubber has simple structure and clear stress principle, but has small bearing capacity, and the support is easy to generate vertical instability when the shear deformation is large; the three-dimensional shock insulation support of the spiral spring and the disc spring has larger vertical height, and the problems of stability, swinging and the like need to be solved; the air spring three-dimensional shock insulation support is at risk of gas leakage; the vertical TMD system can only play an energy consumption effect in a fixed earthquake frequency section, and when the frequency of the actual earthquake exceeds the designed frequency range, the system can increase the vertical earthquake motion response of the structure.
Generally, although the existing vertical vibration isolation devices have advantages, the existing vertical vibration isolation devices are still not seen in engineering practice application, and no reasonable and feasible vertical vibration isolation devices are used for engineering popularization and application at present. Therefore, it is highly desirable to provide a vertical seismic isolation apparatus that is feasible in terms of apparatus construction, performance, economic applicability, etc.
