Abstract
The invention discloses a self-reset rubber shock insulation support device which comprises a lower bottom plate.A cylindrical core support with a round groove in the top face is arranged in the middle of the lower bottom plate and sleeved with an elastic assembly.A plurality of round steel balls are arranged in the round groove.The lower bottom plate is covered with an upper bottom plate with a round protrusion.The round protrusion is in contact with the round steel balls.The upper end and the lower end of the elastic assembly are in contact with the upper bottom plate and the lower bottom plate respectively.By means of the round steel balls and the elastic assembly arranged between the lower bottom plate and the upper bottom plate, transfer of vibration energy to a building structure is separated or reduced during an earthquake, the power response of the upper structure is reduced, a new path of structural earthquake resisting is achieved, and the advantages of being define in force transfer, high in efficiency, high in adaptive capacity to environment, free of pollution and the like are achieved in the use process.
Description
[technical field]
The invention belongs to building structure shockproof control field, be specifically related to a kind of Self-resetting rubber earthquake isolation support device.
[background technology]
During by cutting off earthquake, vibrational energy is to the transmission of top building structure, reduce the geological process of superstructure, thus the security performance realizing superstructure and inside configuration equipment etc. ensures, it is proven in engineering practice, and be widely used, this technology and seismic isolation technology, when its essence is earthquake, the vibration of superstructure and the motion of bearing are separated, by increasing the deformability of structural system and providing necessary damping to realize.
Rubber earthquake isolation support conventional in current engineering is by arranging high damping material lead at core position, suitable damping and restoring force are provided, but, increase along with the time of use, there is the hidden danger that lead is revealed in this type of bearing, easily causing environmental pollution, at present, American-European countries has limited using and promoting of lead rubber laminated bearing.
[summary of the invention]
It is an object of the invention to overcome above-mentioned deficiency, it is provided that a kind of Self-resetting rubber earthquake isolation support device, solve existing lead rubber laminated bearing and environment is existed the hidden danger polluted and the problem that after general shock isolating pedestal deformation, self-healing is not good.
In order to achieve the above object, the present invention includes lower raft, the middle part of lower raft is provided with the cylindrical core supporting that end face is circular groove, core supporting outer sheath is provided with elastic parts, some round steel pearls it are provided with in circular groove, lower raft is coated with the top base plate with circular protrusions, circular protrusions all contacts with some round steel pearls, elastic parts includes some layers of steel plate pad, the steel plate pad being filled with rubber spacer, top and bottom between adjacent steel plate pad contacts with portion's base plate and lower raft respectively each through rubber spacer.
Offering annular slotted in described circular groove, some round steel pearls are arranged in annular slotted.
Described top base plate, elastic parts are square or that diameter is identical revolving body with lower raft.
The outside of described top base plate, elastic parts and lower raft is provided with rubber cover.
The outside molded line of described circular protrusions matches with the outside molded line of circular groove.
Described top base plate is provided with some connection crab-bolts.
Some bottoms crab-bolt it is provided with bottom described lower raft.
Described circular protrusions is that semicircle is spherical.
Compared with prior art, the method have the advantages that
1, the present invention is by being arranged on round steel pearl between lower raft and top base plate and elastic parts, cut off or reduce during earthquake vibrational energy to the transmission of building structure, reduce the dynamic response of superstructure, achieve the new way of structural seismic, in use there is power transmission clear and definite, good high efficiency and the advantage such as adaptive capacity to environment is strong, pollution-free；
2, the simple structure of the present invention is practical, dependable performance, and during by earthquake, the vibration on ground cuts off or reduces the transmission to superstructure, and upper load is transferred to basis by circular protrusions with core supporting；
3, when superstructure occurred level moves, owing to structure is arranged, relative horizontal displacement can be there is in elastic parts, therefore its kinetic energy can be converted into the friction between potential energy and rubber sheet gasket, the two effectively reduces its dynamic response situation, and suitable Self-resetting function can be provided, compare and meet civil structure damping stress performance feature.
