The lateral faces of the upper and the lower slide plates are provided with annular elastic spacing elements, and the upper and the lower slide plates are respectively provided with a base flange. The annular elastic spacing elements are clamped between the base flanges, and the elastic spacing element is made of an adoptive special composite material. Double-face slide is changed into single-face slide, with a slug between the two plates omitted. The utility model has simple and compact structure, and because a slide amount is appropriate, the utility model is characterized in uniform stress, reliable abilities of shock insulation and shock damping and long service life, and the surface coating is not easily damaged.
Description
The utility model relates to the antiseismic structure of building, the shock insulation damping device that use particularly a kind of building bottom.
The inventor had once proposed a kind of two-sided slip earthquake isolating equipment in Chinese patent ZL94214038, its structure is that the slippage pellet is arranged between the upper and lower plates, at the assembling limit Cheng Huan of force bearing plate slippage edge.The two-sided slip device though total slippage is bigger, still has some weak point.When device was in maximum slip state, force bearing plate was maximum cantilever with respect to pellet up and down, and plate is subjected to eccentricity pressure, the surface stress complexity, and stress raisers are serious, cause the face coat subject to damage, influence functional reliability and working life.The 2nd, this device has two parallel slide surfaces up and down, double glide face structure requirement on machining accuracy height, manufacturing process complexity, processing cost height.The 3rd, this apparatus structure more complicated, poor stability.The 4th, can't reset after the action.
The purpose of this utility model is the above-mentioned weak point that will overcome prior art, and provides a kind of stress good, and reliable operation is simple in structure and have a sliding plate earthquake isolation device necessarily spacing, reset function.
Solution of the present utility model is: upper and lower sliding plate is directly contacted, and the spraying friction factor is 0.02～0.08 and wear-resistant corrosion resistant coating on the slide plane between the upper and lower sliding plate.When taking place, earthquake can slide relatively between the sliding plate up and down like this.
Described upper and lower sliding plate preferably has base flange respectively.
The elasticity limit element of annular can be set in the side of upper and lower sliding plate, and this cyclic spring limit element is clamped between the base flange.
Above-mentioned elasticity limit element should adopt composite material to make.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is a sliding plate earthquake isolation device overall structure schematic diagram.
Fig. 2 is that Fig. 1 removes the vertical view of going up sliding plate
Fig. 3 is the partial enlarged drawing of sliding plate and limit element connection place.
Fig. 4 is the user mode schematic diagram of sliding plate earthquake isolation device between building and basis.
Fig. 5 is the working state schematic representation after sliding plate earthquake isolation device produces slippage.
Referring to Fig. 1,2, sliding plate earthquake isolation device comprises sliding plate 1 and down-shift board 3.Upper and lower sliding plate is in direct contact with one another, and bears the load of building.Thereby the pellet about having saved in the prior art between the sliding plate.Be provided with the elasticity limit element 2 of annular among the figure in the side of upper and lower sliding plate 1,3, limit element is made by composite material, as cord rubber composite or the higher composite material of other intensity.Sliding plate then adopts ordinary carbon steel to get final product.
Upper and lower sliding plate 1,3 is preferably with base flange 4,5, cyclic spring limit element 2 can be clamped between the base flange 4,5.Limit element 2 existing certain elasticity have very high intensity again, are supported between the upper and lower sliding plate, can reduce the normal pressure between sliding plate, and then reduce interleaf friction power, make slippage become more easy.
Referring to Fig. 3, connect by screw thread 8 between upper and lower sliding plate 1,3 and the cyclic spring limit element 2.Sliding plate base flange 4,5 has band saw teeth groove 9 embedding mutually with the end face of cyclic spring limit element 2.This structure makes the connection between sliding plate and the limit element more firm.The two is coupled as one, and can increase the drag of distortion.
Referring to Fig. 4, because the elastic deformation and the damping action of limit element 2, can the absorption portion seismic energy.When upper and lower sliding plate relatively moved, its relative slippage L obviously reduced.Effectively limited a large amount of slips relatively between upper and lower sliding plate, making slides is limited in proper range.And have and make slide plate return to the trend of origin-location.Can when small earthquake, rise and reset, play a part spacing during violent earthquake.
Contact surface at upper and lower sliding plate 1,3 should be coated with low-friction coefficient (0.02～0.08), wear-resistant, corrosion-resistant, fatigue proof coating.As materials such as ceramic coated, tungsten carbide, alloy or poly-tetrafluoros.
Referring to Fig. 5, sliding plate earthquake isolation device generally places the building bottom, and the last collar tie beam 6 of wherein going up sliding plate 1 and architecture bottom layer fixes, and down-shift board 3 fixes with the lower ring beam 7 on basis, thereby forms many slidably fulcrums between building and basis.When earthquake causes ground level when motion, isolator can make building keep motionless substantially, thereby avoids or alleviate the heavy damage that earthquake causes building.
The utility model compared with prior art has following advantage:
1, the single face Sliding Structures is owing to the pellet that has saved between two plates, and simple and compact for structure, stationarity is good.
2, the coefficient of friction between the upper and lower sliding plate can be controlled between 0.02～0.08. Slippage between plate can Be controlled at 30～96mm. Thereby can under littler horizontal force action slippage take place. Various earthquake magnitude earthquakes are had Good comprehensive earthquake isolation characteristic. Be widely used in building construction, bridge and some petrochemical equipment etc. Earthquake isolation.
3, changing two-sided slip is the single face slippage, because the slippage appropriateness, upper and lower sliding plate offset is littler, The cantilever force state is greatly improved. Stressed evenly face coat is difficult for impaired, and the earthquake isolation ability is reliable, Long working life.
4, owing to avoided the cantilever force situation, the rigidity of slide plate improves, and can bear huge vertical load, The building vertical deformation is small.
5, behind the elastic spacing deformed element, powerful automatic recovery trend is arranged, make building structure multiple when little shake The position, spacing when shaking greatly.
6, the single face slide device is simple in structure, is easy to make, and is cheap, convenient for installation and maintenance, be easy to promote.
