Abstract
The invention relates to a reversible anti-dumping composite rubber seismic isolation support. The reversible anti-dumping composite rubber seismic isolation support comprises a rubber isolation support body, rotating half-grooves, a reversible upper connecting shaft plate, a damping material and a sliding surface material; the sliding surface material on the reversible upper connecting shaft plate is aligned to and tightly attached to the concave surfaces of the two rotating half-grooves together; the rotating half-grooves are fixed with the upper connecting plate of the rubber isolation support through bolts; the damping material is added to a clearance between the rotating half-grooves and the reversible upper connecting shaft plate; the reversible upper connecting shaft plate can freely rotate when the reversible anti-dumping composite rubber isolation support is subjected to a bending moment action; the damping material plays a role of dissipating energy; an outer convex flange of the reversible upper connecting shaft plate and inner convex flanges of the rotating half-grooves play a role of preventing the support from dumping. According to the reversible anti-dumping composite rubber seismic isolation support, the condition that the rubber isolation support is damaged because of the bearing of the bending moment is solved, the effects of seismic isolation and energy consumption of the rubber isolation support are sufficiently exerted, and the safety of the structure under the action of earthquake is ensured.

Background technology
Structure uniformity is that maximum a kind of shockproof control modes is applied in domestic and international research the earliest.From current situation, Structure uniformity all achieves a lot of achievement in theory with in application.Passive Control does not need extra power, and its principle installs shock insulation or other energy dissipators at some position of structure, reduced the control mode of earthquake response by self power consumption.Because Passive Control has cheap, simple structure, is easy to safeguard and without the need to advantages such as extra power supports, obtains pay close attention to widely and be widely used in Practical Project at civil engineering field.
Rubber earthquake isolation support, as a kind of full-fledged energy-dissipating and shock-absorbing technology, is at home and abroad used widely in many Practical Projects.Structure is when suffering geological process, and drive rubber earthquake isolation support to move together, rubber earthquake isolation support relative motion produce power dissipates, thus reaches the object reducing earthquake response.
The rubber earthquake isolation support used in current engineering mostly is lead rubber bearings or lead rubber laminated bearing.Above-mentioned rubber earthquake isolation support can only horizontal movement, can not bear Moment, and when being subject to Moment, bearing two ends can produce the situation that tension and compression do not wait, and cause support damage, engineer applied is not too convenient.One can be designed and can reverse overturning or slip resistance analysis compounded rubber shock isolating pedestal, when making can reverse overturning or slip resistance analysis compounded rubber shock isolating pedestal by Moment, holder top is free to rotate, avoids rubber earthquake isolation support two ends to occur the situation that tension and compression do not wait making rubber earthquake isolation support from destruction.How to design one can reverse overturning or slip resistance analysis compounded rubber shock isolating pedestal and replace rubber earthquake isolation support, solve tensile failure when rubber earthquake isolation support bears Moment is an insoluble engineering roadblock always.
Summary of the invention
The object of the invention is to the defect existed for existing seismic isolation technology, provide one can reverse overturning or slip resistance analysis compounded rubber shock isolating pedestal, make this device top can FREE TORSION, avoid rubber earthquake isolation support tensile failure, give full play to the shock insulation power consumption effect of device.
For achieving the above object, the present invention adopts following technical proposals:
One can reverse overturning or slip resistance analysis compounded rubber shock isolating pedestal, comprises rubber earthquake isolation support, rotates half groove, can reverse and connect axillare, damping material and slide plane material; The described slide plane material reversed on connection axillare aligns with two pieces of concave surfaces rotating half groove, be close together, the upper junction plate of described rotation half groove and rubber earthquake isolation support is bolted, and is connected in the space of axillare on described damping material joins rotation half groove and can reverse; Described reverse connection axillare can reverse overturning or slip resistance analysis compounded rubber shock isolating pedestal by Moment time can freely rotate, damping material plays the effect of dissipation energy; The effect of bearing overturning or slip resistance analysis is played on the convex edge of a wing on described the evagination edge of a wing and rotation half groove of reversing connection axillare.
Described rubber earthquake isolation support is normal stack neoprene bearing, lead rubber bearing, high damping laminated rubber bases, thick rubber laminated rubber bases, tension laminated rubber bases or prestress rubber bearing.
