Description
Technical field
The utility model relates to a kind of earthquake isolating equipment, is specifically related to a kind of shock isolating pedestal of realizing that many performance objectives are set up defences, particularly a kind of three stages power consumption shock isolating pedestal.
Background technology
As a kind of important natural calamity, the characteristics such as that earthquake has is sudden, unpredictability, be identical without any twice seismographic record in history, and the strong randomness of earthquake has been brought certain test to providing fortification against earthquakes of building.At present, China reaches the earthquake resistant code of many countries in the world and generally formulates according to three levels of setting up defences such as little shake, middle shake, large shakes, the level of setting up defences in certain area has comprised distinct statistical significance, therefore a following earthquake occurred in area is likely to surpass expection intensity.About super expected earthquake effect, scholars have proposed the megaseisms concept outside level is set up defences in large shake, middle shake, little shake, and it characterizes the extreme earthquake disaster that surmounts large shake on amplitude.The important building for function is introduced the building aseismicity fortification measure under super expected earthquake in the traditional design theory, and have important practical significance and be worth, and the perfect to a certain extent Aseismic Design Theory framework based on performance.
As a kind of effective damping device, shock isolating pedestal has worldwide obtained popularization and application at present.1969,3 layers of modern shock-insulation building of First appearred in Yugoslavia, adopted natural rubber.1981, Wellington, NZL William Clayton (William Clayton) building adopted lead core rubber support as earthquake isolating equipment first.Development so far, Japan's shock-insulation building has increased to more than 1000, and also existing hundreds of seat shock-insulation building of China, and in highway bridge extensive application, be distributed in 20 provinces and cities such as Beijing, Shanghai, Xinjiang, Henan, Jiangxi, Guangdong, covered the most of earthquake of China district that sets up defences.The shock insulation design has write China " seismic design provision in building code GB50011-2010 ", is the most effective, the most universal damping device of application.
In recent years, Chinese scholar has been researched and developed the various new shock isolating pedestal, the characteristics such as high damping, highly energy-consuming, multidimensional damping, technique be simple have been embodied respectively, the core that combines as plumbous as the steel of the research and development such as Wang Hao, Li Aiqun subtracts shock insulation rubber bearing, there are the characteristics such as damping is large, power consumption is stable, earthquake displacement is little, mild steel-the rolling shock insulation support of the research and development such as Xue Suduo, there is power transmission and clearly stablize, be convenient to fabrication and installation, the advantage such as practical, the double-layer multi-dimensional shock absorption device of the research and development such as Xu Zhaodong, can be to horizontal bidirectional and vertical damping simultaneously, and cheap.Yet, consider that there is certain drawback in common shock isolating pedestal under macroseism, that is: under the macroseism, excessive, the vertical compression area of shock isolating pedestal sidesway reduces, easily cause vertical unstability, simple built-in lead for retractable pencil laminated steel plate neoprene bearing energy dissipation capacity deficiency of while, also lack multistage energy-dissipating and shock-absorbing mechanism, can not meet many performance objectives of advocating at present and set up defences.Based on this, be necessary to research and develop a kind of novel earthquake isolating equipment that can guarantee reliably working under super expected earthquake and can realize the multistage energy-dissipating and shock-absorbing.
