Description
Technical Field
The invention relates to the technical field of building structure and equipment shock insulation, in particular to an anti-collision three-dimensional shock insulation support which is started after earthquake early warning and moves a balance position.
Background
Between the two major seismic zones in china, the eurasia seismic zone and the pacific seismic zone, is one of the most serious countries in the world suffering from seismic hazards. Historically, severe earthquakes of more than 6 grades have occurred many times in Yangtze river delta and Zhu river delta, and in the Bohai area of Kyoto hoop, a major earthquake of more than 7 grades occurs every 44 years on average in nearly 300 years. With the acceleration of urbanization process, a great amount of national wealth is rapidly concentrated to cities and urban cluster areas. More than one third of the established or proposed urban groups in China are located in areas where major earthquakes of more than 7 levels are likely to occur. The buildings which account for the vast majority of cities in China are reinforced concrete multi-storey and high-rise buildings which have wide use functions, and economic loss and casualties caused by the damage of the buildings cause great impact on national safety and social stability. The earthquake is that when the stratum of the earth crust is in a complex stress state and the action of the earth stress exceeds the ultimate strength of the stratum at a certain position along with the continuous change of the earth crust, the stratum can be suddenly broken and dislocated, so that the earthquake is caused, and is transmitted to the earth surface in the form of elastic waves, so that an object with certain mass near the earth surface generates inertia force, and when the self seismic capacity of the object for resisting the inertia action is insufficient, the object is damaged. When the excellent period of the local vibration is closer to the natural vibration period of the object, the damage of the object is more serious. The natural vibration period of the object can be obviously changed by arranging a certain vibration isolation device on the object, so that the excellent period of the earthquake is avoided, the inertia force acting on the object is obviously reduced, the damage of the object under the action of the earthquake is reduced, and the safety of the object under the earthquake is improved.
The seismic isolation technology essentially prolongs the natural vibration period of the structure by reducing the rigidity of the seismic isolation layer, so that the rigidity of the seismic isolation layer is generally small, large deformation can occur under the action of wind load, crowd load and other loads, and even serious damage can occur in severe cases, so that the application of the seismic isolation technology also has limitation. Analyzing the efficiency of the time scale of the seismic isolation technology, the fact that only the short time of the seismic action really acts on the common seismic isolation technology is that much time is not effective or even counterproductive. Therefore, the ideal seismic isolation technology should not work at ordinary times, only work temporarily when the earthquake happens, and stop working after the earthquake is over. The earthquake short-term forecasting and earthquake early warning technology brings application space for the application of the technology, and at the present stage, the earthquake short-term forecasting technology is extremely difficult to develop, but the earthquake early warning technology is developed vigorously, and after an earthquake occurs, the earthquake early warning technology can strive for precious but short time for earthquake defense setting by utilizing the principle that the light speed is faster than the earthquake wave speed, and the short time makes the transformation of the traditional earthquake isolation technology possible.
In addition, under many circumstances, because two buildings or two equipment are close apart from each other, the collision of two article can arouse because of vibrations to adjacent side, and under many circumstances, this kind of adjacent side can not be allowed to collide, consequently need restrict the deformation of isolation bearing, especially to the object of high-speed motion like high-speed train, can not cause the collision between two high-speed trains because of the existence of isolation bearing, the spacing scheme of vibrations direction will reduce shock insulation efficiency. In addition, the seismic isolation support can have residual plastic deformation under the action of strong shock, which affects the normal use of structures or equipment, for example, if a train has horizontal lateral residual deformation, the train can hardly enter a station, and the risk of collision can also be caused. For a class of equipment similar to trains and some civil buildings traversed by rail traffic, it is normally necessary to damp them, but it does not allow large horizontal deformations.
