Description
Technical field
The utility model relates to building, isolation bridge technical field, in particular, relates to a kind of novel Self-resetting shock isolating pedestal.
Background technology
China is positioned at the impact area in the large multiple district of violent earthquake of circum-Pacific seismic belt and Eurasian earthquake zone two, is the multiple country of an earthquake.How antidetonation and damping is built to improve, the anti-seismic performance of bridge is the problem of carrying out building, bridge design must be paid much attention to.Building, isolation bridge technical field in, than be easier to realize and effective shock-dampening method be employing shock isolating pedestal.The isolation measure adopted both at home and abroad at present mainly comprises rubber earthquake isolation support, sliding isolated bearing, friction pendulum support, rolling shock insulation device etc.
Neoprene bearing has enough vertical rigidities to bear vertical load, and the pressure of superstructure can be passed to pier or basis effectively; There is good elasticity to adapt to the rotation of superstructure; There is larger shear strain to meet the horizontal movement of superstructure.Outside the gravity that works is born in lead core rubber support decapacitation and horizontal force, the plastic strain of the hysteresis damping that lead for retractable pencil produces can also absorb energy, and provides horizontal restoring force by rubber.But because main functionality i.e. vertical carrying and the horizontal shear of this system bearing is all realized by rubber with reset, therefore require should take into account above functional realiey in the processing and fabricating of rubber compounding and neoprene bearing shock insulation, its difficulty is very big, is difficult to obtain effective guarantee.When the anti-shearing deformability of rubber and restoring force deficiency, superstructure usually can produce excessive horizontal movement, even causes falling beam or topples.
Tradition sliding isolated bearing arranges the slippage original paper of low friction and locating part etc., seismic energy is effectively limited to top transmission and lower portion feedback by Relative sliding motion and friction energy-dissipating, but only by friction energy-dissipating and without other power consumption mode, during its earthquake, displacement is excessive easily damages limit element, need to arrange resetting-mechanism separately, difficulty of construction is large simultaneously.Friction pendulum support does not have above-mentioned restriction, but its high cost hinders its extensive use.In addition, it also can cause structure lifting.
Have scholar to propose can to add between groundsill and foundation circular scrolling rod or spheroid carrys out shock insulation, this rolling shock insulation device advantage is that its coefficient of rolling friction is very little, and isolating affection is good.But this device does not have Self-resetting function, and undamped.Separately there is scholar to advise circular scrolling rod (spheroid) being changed into the oval rod (spheroid) that rolls, but still there is no damping like this, but also structure lifting can be caused.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, requires the high and anti-shearing deformability of rubber and recover hypodynamic defect as: neoprene bearing to rubber; Slip support abutment and circle (ball) shape roller support energy dissipation capacity deficiency, without the defect of reset function; Friction pendulum support and oval (ball) rolling shock insulation device can cause the defect of structure lifting; There is provided a kind of novel Self-resetting shock isolating pedestal, the absorbing vibration energy of the utility model bearing is strong, and automatic recovery capability is strong, bearing amount of side-shift can be avoided excessive, and can not make structure lifting, has structure simple, easy to use, safety advantages of higher.
The purpose of this utility model is achieved through the following technical solutions:
A kind of novel Self-resetting shock isolating pedestal, comprise upper junction plate and lower connecting plate, it is characterized in that, what described upper junction plate was corresponding with the middle part of lower connecting plate is provided with groove, correspondingly in the middle part of described groove be formed with projection, and at the cementing flexible bed course of groove surfaces, the rolling element of elliposoidal is connected with between described elastic layer, symmetrically on the sphere of described rolling element be provided with two grooves, the arranged outside of rolling element have with upper junction plate and under be connected interconnective steel plate lamination rubber cylinder, space is left between described rolling element and described steel plate lamination rubber cylinder, described steel plate lamination rubber cylinder inner circumferential is equally spaced is provided with lead for retractable pencil.
Described lead for retractable pencil is provided with 6-10 root altogether.
Described upper junction plate and lower connecting plate are steel plate.
Described upper junction plate and lower connecting plate are circle.
Described rolling element is that Steel material is made.
Compared with prior art, the beneficial effect that the technical solution of the utility model is brought is:
1. the rolling element arranged between the upper junction plate of the utility model bearing and lower connecting plate and the steel plate lamination rubber cylinder shared vertical load being arranged on rolling element surrounding, the Action of Gravity Field that superstructure during sidesway occurs provides restoring force jointly with the laminated rubber that shear strain occurs, compared with lead core rubber support, decrease depending on unduly rubber, thus the Self-resetting function of the utility model bearing is protected.
2. also equally spacedly in steel plate lamination rubber cylinder of the present utility model be provided with lead for retractable pencil, compared with traditional slip support abutment and circular scrolling bearing, this bearing can also produce damping while having more satisfactory restoring force, bearing amount of side-shift can be avoided excessive, obtain desirable endergonic ability and Self-resetting function simultaneously.
3. all correspondingly inside the upper junction plate of the utility model bearing and lower connecting plate be provided with groove, protruding in the middle part of groove, groove is linear through well-designed, make rolling element when extrusion occurring and rolling, distance between upper and lower junction plate is constant, namely, compared with friction pendulum support and oval roller support, there is lifting in the structure that the utility model bearing can not be made to carry.
4. the groove surfaces of the upper and lower junction plate of the utility model bearing is all cementing high resiliency bed course, contributes to the coefficient of sliding friction improved between itself and rolling element, to force rolling element to roll, and relative sliding does not occur; Meanwhile, the existence of high resiliency bed course makes contact site be territory, face, instead of point, which avoid rigid material contact point place under long-term vertical load and is crushed; In addition, when occurring to clash into, high resiliency bed course plays cushioning effect, and absorbs energy, and these features make the utility model bearing life-span high, and security performance is reliable and shock resistance is strong.
5. in the utility model bearing the vertical loading side of rolling element to sphere on symmetrical be provided with two grooves, buffer capacity and absorbing vibration ability strong, in rolling element rolling process, groove can play position-limiting action with the clamping of groove corner angle simultaneously.
