Description
Technical field
The utility model is related to bearing, and more particularly to one kind subtracts shock insulation rubber bearing.
Background technology
Bearing is one of important composition part in bridge and architectural engineering, and its effect is by the upper of bridge or building structure
Portion's load is delivered on pier by bearing, while the need for ensureing the stress required by structure, displacement and rotation.It is existing to subtract
Shock insulation rubber bearing mainly has common laminated rubber bearing, high-damp rubber support, lead core rubber support etc..High-damping rubber branch
Seat and lead core rubber support damping and isolation effect are preferable, but cost is also of a relatively high, is generally used for earthquake intensity area higher.It is general
Logical laminated rubber bearing only includes support body, and support body is made up of laminated rubber middle setting multilayer stiffened steel plates.Use
When, upper embedded board is installed in support body.Due between the steel plate and rubber in existing common laminated rubber bearing
Faying face be plane to plane, therefore, the contact area between steel plate and rubber is limited, the shearing that the rubber support can bear
Power is also limited, while the vertical bearing capacity of vibration absorption and isolation support and horizontal displacement ability are also limited so that upper and lower shrouding with
Easily suffer that the destruction of shearing force is unable to resist and adapt to bigger geological process in the vulcanization position of rubber body.Cause
This, it would be highly desirable to improve existing common laminated rubber bearing.
The Chinese utility model patent of Patent No. ZL201120071407.5 belongs to technical field of bridge, discloses
A kind of steel ball-crown laminated rubber bearing.It is mainly characterized in that：Rubber slab including being provided with steel plate, the rubber slab it is upper
It is the upper steel baseplate that the lower steel baseplate on convex surface and bottom surface are concave surface, top surface is plane, lower steel for plane, top surface that portion is provided with bottom surface
The convex surface of seat board matches with the concave surface of upper steel baseplate.A kind of steel ball-crown laminated rubber bearing that the utility model is provided,
Lower steel baseplate and upper steel baseplate, the convex surface of lower steel baseplate and the concave surface phase of upper steel baseplate are provided with above common laminated rubber bearing
Matching, makes bearing have centripetal restoring force all the time, during Luo Liang, even if there is scene and construction error, the lower steel for matching
The concave surface of the convex surface of seat board and upper steel baseplate also can voluntarily adjust under the effect of centripetal restoring force, from partially existing without pressing
As so that Bearing Seat Force is uniform, extends the service life of bearing.But the utility model is not to the combination between steel plate and rubber
Face is improved, both faying faces still for plane to plane, therefore, the contact area still suffered between steel plate and rubber has
The limited technological deficiency of the shearing force that limit, can bear, while still suffering from the vertical carrying energy of the steel ball-crown laminated rubber bearing
The technological deficiency of power and horizontal displacement limited ability, above-mentioned technological deficiency causes that steel plate easily meets with the vulcanization position of rubber body
Destruction to shearing force is unable to resist and adapt to bigger geological process.
The Chinese utility model patent of Patent No. ZL201320251200.5 disclose a kind of New type agitation main frame subtract every
Vibrating device, including upper base plate, subtract vibration isolation rubber element and lower seat board, it is described subtract vibration isolation rubber element be fixedly installed on upper base plate and
Between lower seat board.The utility model beneficial effect：Using high-damping vibration isolation rubber element is fixedly installed between upper and lower seat board
Novel damping structure, can preferably bear and clear up vertical pressure and horizontal shear force, and structure is more excellent, can effectively drop
The vibration effect of low stirring host.But the utility model equally not to upper base plate and subtract faying face between vibration isolation rubber element,
Lower seat board and the faying face subtracted between vibration isolation rubber element are improved, i.e., upper and lower seat board with it is described subtract vibration isolation rubber element it
Between faying face still for plane to plane, therefore, still suffer from upper and lower seat board and the contact surface subtracted between vibration isolation rubber element
The limited technological deficiency of product shearing force that is limited, can bear, holds while still suffering from the stirring host and subtracting the vertical of isolation mounting
The technological deficiency of loading capability and horizontal displacement limited ability, above-mentioned technological deficiency causes that upper and lower seat board subtracts vibration isolation rubber with described
Easily suffer that the destruction of shearing force is unable to resist and adapt to bigger geological process in the vulcanization position of element.
Utility model content
