Description
Technical Field
The invention relates to a building shock isolation system for a building.
Background
In 2008, 12 days, 8.0-level earthquakes occur in Wenchuan in Sichuan, and the information disclosure of earthquake-stricken areas shows that casualties in Wenchuan earthquake are mostly caused by collapse of houses such as factories, office buildings, schools, houses and the like, so that the population density gathered in cities and towns is increased along with the development of urbanization construction in China, and the house with earthquake safety is a difficult problem which must be faced and solved by people. The building constructed by adopting the seismic isolation technology at home and abroad obtains great achievement in the aspect of building seismic safety, the house constructed by adopting the building seismic isolation technology is tested by the earthquake, the good seismic isolation effect is shown, and the building is safe and careless after the earthquake. China is continuously innovated in the field, and various building shock isolation systems are applied to engineering practice. The seismic isolation technique is to arrange a soft layer between the superstructure and the building foundation to separate the superstructure from the foundation. When the earthquake of the earthquake-isolating building shows that the earthquake occurs, the soft layer can generate large horizontal deformation, most of earthquake energy is isolated and consumed through the large horizontal deformation, the input of the earthquake energy to an upper structure is reduced, the earthquake force transmitted to the upper structure of the building by the earthquake is effectively reduced, and the building safety is ensured. Different shock insulation systems are selected for the shock insulation technology to play a vital role in the shock insulation effect of buildings, and currently, building shock insulation systems adopted at home and abroad mainly have three types: the first type is a combined type building shock insulation system adopting a lead core shock insulation rubber support and a common shock insulation rubber support, namely, the lead core shock insulation rubber support is installed on one part of upper and lower buttresses of a building, and the common shock insulation rubber support is installed on the other part of the upper and lower buttresses. The system is characterized in that the core component, namely the shock insulation rubber support, is generally an integral laminated rubber support structure formed by sandwiching a thin steel plate between a plurality of layers of rubber through vulcanization, the rubber support and a central lead-added core are lead core shock insulation rubber supports, and the lead-added core-free rubber support is a common shock insulation rubber support. The combined system can prolong the natural vibration period of the house, keep the house away from the characteristic period of earthquake waves, reduce the earthquake action and have the automatic reset function. But the defects are obvious, and because the integral vertical bearing gravity, the horizontal shearing force and the resetting force of the support are large and are realized by rubber, the processing and manufacturing difficulty of the rubber formula and the rubber support is very large, and the effective guarantee is not easy to obtain. Moreover, the aging problem of rubber cannot be avoided, any layer of the whole laminated rubber support structure with thin steel plates sandwiched between a plurality of layers of rubber has problems in vulcanization adhesion, the support loses the application function, and meanwhile, the problems that the vertical tension is generated in the application of high-rise buildings, the buildings are easy to overturn and the like occur. The isolation of rubber bearings currently used in engineering practice has revealed a number of problems, including the use in such important buildings as airport terminals.
The second type of shock insulation rubber support and single-layer elastic sliding shock insulation rubber support combined building shock insulation system is characterized in that the shock insulation rubber support is partially installed on an upper buttress and a lower buttress of a building, and the single-layer elastic sliding shock insulation rubber support is installed on the rest portion of the upper buttress and the lower buttress of the building. The system is characterized in that a part of upper and lower buttresses of the building is provided with a shock insulation rubber support, the rest part of the upper and lower buttresses is provided with a single-layer elastic sliding shock insulation support, the system solves the problems that vertical tension can be generated when a high-rise building with the upper structure is used, the building is prone to overturning and the like, the basic structures of the two supports are of a laminated rubber support structure, the rubber formula and the large laminated rubber support are extremely high in processing and vulcanizing difficulty, the product quality is not easy to be effectively guaranteed, the detection cost is high, and the aging problem of rubber still. The single-layer elastic sliding shock insulation support has the defects that the whole shock insulation support body is large in structural size and the like due to the fact that the single-layer elastic sliding shock insulation support can only slide in a single layer mode.
The third kind of building shock isolating system with friction pendulum shock isolating support includes upper and lower buttresses, and friction pendulum shock isolating support installed on the buttresses. The friction pendulum bearing consumes energy by utilizing sliding friction of two curved surfaces, and through designing a large concave curved sliding surface, the vibration period of a building structure is prolonged by translating on a circular arc with a large spherical radius, so that the amplification effect of the structure caused by the earthquake action is reduced, and meanwhile, the system can automatically reset by depending on gravity after the earthquake is finished, the system needs to process at least 4 spherical surfaces by using the friction pendulum shock insulation bearing, the processing difficulty is large, meanwhile, the concave curved surface needs to be welded with a thin stainless steel plate, particularly, the large concave curved surface is not easy to enable the stainless steel plate to be completely attached to the corresponding concave curved surface, when the earthquake occurs, the mechanism of the motion of the friction pendulum shock insulation bearing is that the friction pendulum shock insulation bearing horizontally slides when rotating, the stainless steel plate can tear when rotating and sliding, the bearing loses functions, and loses.
Above three kinds of shock insulation support systems all have the support in use and damage the back and change and must wholly change the support, because upper and lower bedplate is connected with upper and lower buttress pre-buried sleeve bolt with the bolt, does not push away building superstructure jack installation space again, changes almost unable realization. The shock insulation rubber support adopted in the first and second shock insulation systems with the laminated rubber support as the core has the advantages that the design pressure is only 10-15 Mpa, the overall dimension of the support bearing the same vertical load is large, and the diameter of the support applied in the existing building reaches 1500 mm. The horizontal rigidity is increased, so that the shock insulation efficiency of the support is greatly reduced, meanwhile, due to the increase of the horizontal rigidity, the horizontal force is increased, the corresponding tilting force of a high-rise building is increased during earthquake, the rubber shock insulation support faces the tensile stress of more than 1 Mpa, the tensile stress exceeds 1 Mpa, a tensile device is independently arranged, and the construction difficulty and the construction cost are high. In addition, the processing difficulty of the ultra-large shock insulation rubber support is high, the rubber vulcanization is not good, the horizontal performance of a finished product is detected, and the product quality is ensured to be easy to talk about in the face of difficult production and detection. Over time, the problem of aging of rubber isolation bearings is further exposed, the expected performance parameters of the bearings are greatly reduced, and the temporary occurrence of an earthquake is very dangerous. Because the rubber shock insulation support is always under the pressure action of a large tonnage, once the quality problem occurs, the whole building needs to be synchronously jacked, the operation difficulty is conceivable, and the rubber shock insulation support can not be replaced almost.
