Description
Technical field
The utility model relates to building structure technical field of isolation, especially relates to a kind of base isolation device.
Background technology
Earthquake is serious natural calamity, it is that the energy slowly accumulated due to earth interior discharges suddenly and the epidermic vibration caused, strong ground vibration can directly and indirectly cause collapsing and destroying of building, bring serious threat to the lives and properties of people, also can cause huge economic loss to society.
Therefore, the antidetonation of building structure is that world's All Countries must be considered when building construction.Building opposing earthquake is mainly by two approach, first is the intensity increasing structure, make structure under the geological process of expection earthquake intensity, ensure the safety of structure, second is between agent structure and foundation structure, arrange the very little separation layer of horizontal rigidity, agent structure is isolated in the horizontal direction substantially with the earth, and the energy of earthquake not easily passes to agent structure, thus avoids agent structure to destroy.The type of existing base isolation has: laminated rubber shock insulation, sliding friction shock insulation, rolling shock insulation, shock insulation principle respectively: cycle stretch-out, energy absorption, insulation.Insulate method more satisfactory in this few class shock isolation method, this is because rolling isolation has directionality, and the direction of earthquake is uncertain, so ball shock insulation is more reasonable.
Existing building energy dissipating spacer assembly, some complex structures, cost is high, some self-resetting ability, and some weakening components are excessive, can be excessive because of the accumulation of microseism slippage, causes sliding phenomenon, affects building normal usage function.
Utility model content
The technical problem that the utility model solves is, provide a kind of structure simple, horizontal rigidity is little, has good elastoplasticity and auto-reset function, the building structure spacer assembly that isolating affection is good.
The technical solution of the utility model is, a kind of base isolation device, comprises upper base plate, middle steel plate, lower seat board, elastic buffer ball, vertical helical spring, horizontal helical spring, steel ball; One deck elastic buffer ball is equipped with between described upper base plate and middle steel plate, described vertical helical spring is fixed between described middle steel plate and lower seat board, described steel ball is placed in the pit of lower seat board, the surrounding of described middle steel plate is provided with back-up ring, and described horizontal helical spring is fixed between the side of described back-up ring and lower seat board.Horizontal helical spring, vertical helical spring, steel ball, elastic buffer ball combine by this spacer assembly dexterously, and isolating affection is very good.
In such scheme, described vertical helical spring has 6-12 group, and often organize 2-4, vertical helical spring plays good function of shock insulation.
In such scheme, described horizontal helical spring is evenly arranged in the surrounding of lower seat board, and each side arrangement 4-8, horizontal helical spring can reduce the horizontal rigidity of whole device, and elastoplasticity is good, opposing cross shear.
In such scheme, described pit is spherical or elliposoidal, and the ratio of slope of pit is comparatively mild, ensures the stationarity of steel ball motion.
In such scheme, place 1-3 steel ball in described each pit, middle steel plate can rotate on steel ball, and together with vertical helical spring, acting in conjunction reduces response acceleration and the distortion of superstructure.
The beneficial effects of the utility model are as follows:
The first, the horizontal rigidity of the utility model separation layer is little, has good elastoplasticity, can produce certain elastic deformation under shearing force effect, dissipation seismic energy, thus makes the earthquake response of superstructure also less, more favourable to superstructure.
Second, the utility model spacer assembly is when earthquake occurs, middle steel plate can rotate on steel ball, together with vertical helical spring and elastic buffer ball, acting in conjunction reduces response acceleration and the distortion of superstructure, reduces the transmission of vibration to superstructure, after earthquake occurs, steel ball can rely on again self gravitation to turn back to the bottom of pit, automatically restores to the original state.
3rd, the utility model structure is simple, reasonable in design, cheap, easy construction, and isolating affection is better, earthquake disaster mitigation, reduces casualties and property loss.
