Technical field
The utility model is related to a kind of earthquake isolating equipment, and in particular to a kind of friction energy-dissipating type rubber support combined isolation dress
Put.
Background technology
In recent years, highlight lines area violent earthquake frequently occurs, and is mostly occurred for cities and towns multilayer, small sized multiple story building serious broken
It is bad, such as Gansu, Sichuan, Ningxia area.Seismic isolation technology has good damping effect, therefore, isolation structure is on highlight lines ground
Area widely builds.Rubber support is conventional isolated component.The major control that rubber support is chosen during shock design refers to
The displacement of rubber support when mark is axle power and big shake.Sandwich construction is lighter due to top weight, and axle power typically compares under the post of part
It is small, therefore, choosing minor diameter bearing can just meet the requirement of vertical load, however, under the big shake effect in highlight lines area every
Shake layer deformation is relatively large, and the deformation of minor diameter rubber support often exceeds Bit andits control index, it is therefore necessary to which selection is big straight
Footpath rubber support meets deformation requirements, but selection Big Diameter Rubber bearing has two when carrying out shock design again,
Problem 1 is that Big Diameter Rubber bearing price is high, the full cost for increasing isolation structure from major diameter bearing, causes wave economically
Take；Problem 2 is that Big Diameter Rubber support stiffness is relatively large, and shock insulation stiffness layer is integrally improved, the lower damping property of frequently occurred earthquake effect
Adjustment can be difficult, influence isolation structure damping effect is played, and reduces damping effect.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of friction energy-dissipating type rubber support combined isolation device,
Can solve the problem that the above mentioned problem of prior art.
To reach above-mentioned purpose, the utility model provides following technical scheme：
A kind of friction energy-dissipating type rubber support combined isolation device, the earthquake isolating equipment includes rubber support, is arranged on rubber
Upper junction steel plate above glue bearing and the lower junction steel plate for being provided with rubbing surface being arranged on below rubber support, the rubber
The frictional slip layer being made up of frictional slip material is provided between bearing and lower junction steel plate.
Further, the rubber support includes upper envelope steel plate, lower envelope steel plate and is located at Seismic Isolation of Isolation Layer between the two, described
Seismic Isolation of Isolation Layer is then to vulcanize the overall structure for being formed by steel plate and rubber alternate combinations.
Further, the circumference of the rubber support is additionally provided with outer rubber layer, and the rubber layer thickness is 5mm.
Further, the bottom surface of the lower envelope steel plate of the rubber support is provided with interior caulking groove, and the embedded groove depth is 3 ~
6mm, 10 ~ 20mm of the embedded cell wall thickness.
Further, the lower junction steel plate is set to plane, the frictional slip thickness with the contact surface of frictional slip layer
It is 6 ~ 12mm to spend, and the frictional slip layer is removably arranged in the interior caulking groove of lower envelope steel plate.
The beneficial effects of the utility model are：First, the utility model selects minor diameter rubber support according to axle power, no
It is essential to use Big Diameter Rubber bearing, shock insulation stiffness layer is reduced, cost is reduced, the performance of rubber support can be given full play to；
Secondly, rubbing surface is selected according to minor diameter bearing characteristic, had both ensure that and small rigidity is provided in the range of Deformation control, reach damping
Effect, can provide friction energy-dissipating under big shake effect again, and the damping performance of isolation structure is improve to a certain degree.Therefore, originally
Utility model provides convenient easily condition for the implementation of the shock design and isolation structure of highlight lines area sandwich construction, is
Solve rubber support Deformation control index and isolation structure dampening factor be difficult to reduce between contradiction provide a kind of approach and
Condition.
