Abstract
The utility model belongs to rubber support technical field, specifically discloses one kind and subtracts vibration-insulation damping rubber support.Its main technical schemes include upper and lower both sides be rubber layer, middle part for successively staggeredly superposition steel plate layer and rubber layer form；The side for the bearing body that the above-mentioned staggeredly steel plate layer of superposition and rubber layer are formed is in the shape and structure of evagination.The bearing can not only improve the cutting performance between the steel plate for forming the bearing, so that the damping capacity of the bearing can realize adjustment, and have the characteristics of easy to use.
Description
Technical field
The utility model belongs to rubber support technical field, is related to one kind and subtracts vibration-insulation damping rubber support.
Background technology
Rubber support applies in the reinforcing of building construction, highway bridge and structure, and its shock insulation and damping performance are extremely heavy
Will.Currently forming the structure of the bearing is included as Chinese Patent Application No. is 201510562525.9, application publication number is
A kind of shock insulation rubber bearing disclosed in CN105256909A application for a patent for invention, China Patent No. 95221636.1, authorize
Notification number is a kind of bridge rubber bearing disclosed in CN2229467Y utility model patent, using multilayer steel plates and multilayer rubber
Glue is superimposed to bond and formed, and the bearing of the structure has good horizontal performance, damped coefficient, vertical performance and vertical carrying
The series of advantages such as power.But the bearing of the structure is because no matter its cross section is circular or rectangle, its vertical cross-section
Shape is rectangle.This kind of square-section rubber support is during horizontal large deformation, after particularly horizontal distortion is more than 200%,
The problems such as excessive tension, easy unstability can be produced.Therefore, it is necessary to from the angles of pedestal configurations, consider that bearing shape is particularly
The optimization of vertical cross-section shape, enables the rubber support of phase same material have preferably stable row and stress performance.And China is specially
One kind disclosed in sharp Application No. 201210287881.0, the application for a patent for invention that application publication number is CN102797293A is used for
Shock insulation and the rubber support of damping, the structure of the bearing is formed by the rubber layer and steel plate layer structure of the superposition that interlocks successively from bottom to top
Into, and the cross-sectional area of rubber support is gradually reduced from bottom to top, and the top surface area of rubber support is less than rubber support
Base area.I.e. the bearing is bench-type structure.The bearing of the structure then have stability and cutting performance is good, horizontal total deformation and
The diameter of rubber support and height the characteristics of can reducing in the case of stress condition identical, but the bearing of the structure due to
The contact area of bridge pier is much larger than the contact area with beam body, hence in so that the integral damping coefficient of the bearing becomes big, it makes
With being restricted.
Utility model content
What the purpose of this utility model was just to provide a kind of cutting performance and damping capacity while disclosure satisfy that subtracts shock insulation resistance
Buddhist nun's rubber support.
Technical scheme is used by realizing the utility model above-mentioned purpose：
One kind subtracts vibration-insulation damping rubber support, its structure including upper and lower both sides be rubber layer, middle part for successively staggeredly be superimposed
Steel plate layer and rubber layer form；It is characterized in that：The side for the bearing body that the staggeredly steel plate layer of superposition and rubber layer are formed
Face is in the shape and structure of evagination.
Forming a kind of above-mentioned structure for subtracting vibration-insulation damping rubber support also includes：
--- the shape and structure of described evagination is the trapezium structure of evagination arcuate structure, evagination triangle or evagination；
--- described bearing body cross section is circular or rectangle；
--- the top margin of the vertical cross-section of described bearing body and base are the straight line being parallel to each other, the middle separated time of top margin and
The middle separated time on base overlaps, and two sides of vertical cross-section are along the symmetrical curve of the middle separated time of top margin.
One kind provided by the utility model subtracts vibration-insulation damping rubber support compared with prior art, has advantages below：
First, because the side for the bearing body for forming the bearing is in include arc, triangle or trapezoidal convex shape structure, therefore
The cutting performance between the steel plate for forming the bearing can be not only improved, so that the damping capacity of the bearing can realize tune
It is whole；Second, because the bearing body of the structural bearings is staggeredly the steel plate layer of superposition and rubber Rotating fields is formed successively, therefore have
The characteristics of compressive property is good.
Brief description of the drawings
Fig. 1 is the structural representation provided by the utility model for subtracting vibration-insulation damping rubber support；
Fig. 2 is second of structural representation for subtracting vibration-insulation damping rubber support；
Fig. 3 is the structural representation that the third subtracts vibration-insulation damping rubber support.
Embodiment
The structure and working principle provided by the utility model for subtracting vibration-insulation damping rubber support is made below in conjunction with the accompanying drawings
It is further to describe in detail：
It is a kind of structural representation for subtracting vibration-insulation damping rubber support provided by the utility model as shown in Figure 1.I.e. should

Layer 4 is formed；Wrapped up in the arc rubber layer of evagination the side 5 for the bearing body that the above-mentioned staggeredly steel plate layer of superposition and rubber layer are formed
Structure.
The structure that both ends are thin, middle part is thick is gone to upper and lower just because of the bearing body for forming the bearing so that the shearing of the bearing
Performance greatly improves than the cutting performance of the upper and lower bearing for tube structure；It can be passed through simultaneously according to the requirement of damping capacity
The shape size for adjusting the arcuate structure of side 5 evagination of bearing body is adjusted.
In a kind of above-mentioned structure for subtracting vibration-insulation damping rubber support is formed,
--- the side 5 for the bearing body that the steel plate layer and rubber layer that are staggeredly superimposed are formed can also be in as shown in Figure 2 outer
The trapezium structure of convex triangle or evagination as shown in Figure 3.I.e. when the side 5 of bearing body is in evagination triangle or evagination
During trapezium structure, while can be according to the requirement of damping capacity by adjusting the shape size of the 5 outer male structure of side of bearing body
To be adjusted；
--- the cross section 6 for forming the bearing body of the shock insulation rubber bearing can be circle or rectangular, with full
Foot is different to be needed；
--- the top margin 6 of the vertical cross-section of above-mentioned bearing body and base 61 are the straight line being parallel to each other, in top margin 6 point
