Radial force transmitting can be obstructed.
Summary of the invention
The purpose of the present invention is in view of the deficienciess of the prior art, providing that a kind of structure is simple, realizes radial shock insulation axis
To the shock-absorbing bridge support of support.
To achieve the goals above, a kind of technical solution that shock-absorbing bridge support is taken of the present invention:
A kind of shock-absorbing bridge support includes the elastic rubber column being vertically arranged between bridge pier and bridge bottom surface boss,
Elastic rubber column one end contradict on bridge pier upper surface, the other end contradict on the boss bottom surface of bridge bottom surface, further include have by
Elastic rubber column one end is fixed on bridge pier and the elastic rubber column other end is fixed on the connection machine on the boss of bridge bottom surface
Structure, bindiny mechanism include two nylon jackets and at least three anchor ears, the nylon jacket include be socketed in bridge pier outer peripheral surface or
The thin neck set that thick neck on the boss outer peripheral surface of bridge bottom surface is covered and is socketed in elastic rubber column, is socketed in bridge bottom surface boss
Thick neck set on outer peripheral surface is fixed on the boss of bridge bottom surface through anchor ear, and the thick neck set being socketed on bridge pier outer peripheral surface is solid through anchor ear
It is scheduled on bridge pier, the two thin neck set free ends being socketed in elastic rubber column overlap to form bilayer in the middle part of elastic rubber column
Structure, double-layer structure are fixed in elastic rubber column through anchor ear, and each anchor ear makes nylon jacket in tight state.
When the invention works, under normal circumstances, elastic rubber column supporting bridge, nylon jacket wrap up elastic rubber column, reduce
Elastic rubber column radially extends out, and promotes the intensity of elastic rubber column, while thick neck set package bridge pier and bridge bottom surface boss, is promoted
Bridge pier free end end and bridge bottom surface boss free end end intensity avoid bridge pier free end end and bridge bottom surface boss certainly
By holding end to be pressurized and chipping.
Compared with prior art, the invention has the benefit that due to nylon jacket presence, thin neck set package elastic rubber
Column promotes the intensity of elastic rubber column, avoids elastic rubber column compression is radial from extending out and be damaged, thick neck set package bridge pier free end
Outer peripheral surface or bridge bottom surface boss free end outer peripheral surface, promote bridge pier free end end and bridge bottom surface boss free end end is strong
Degree avoids bridge pier free end end and bridge bottom surface boss free end end from being pressurized and chipping, and due to anchor ear and nylon jacket
It matches, is flexibly connected elastic rubber column and bridge pier, bridge, when earthquake occurs, the radial force of bridge pier is hindered through elastic rubber column
Every, and avoid being transmitted on bridge.
More nylon bandages are equipped at intervals on the two nylon jacket outer walls, each nylon bandage is with corresponding nylon jacket center
It is arranged centered on axis in radioactivity.Each nylon bandage effectively improves nylon jacket intensity.
Equal spiral winding is connected with more nylon bandages on the two nylon jacket inner walls.The nylon bandage of spiral winding setting
Under the premise of guaranteeing nylon jacket toughness, the intensity of nylon jacket is improved.
Antiskid elastic rubber layer is all covered on the anchor ear inner wall contacted with nylon jacket.
There are the gaps convenient for the dislocation of elastic rubber column local radial between adjacent anchor ear.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Wherein, Bridge 1 pier, Bridge 2 beam, 3 elastic rubber columns, 4 bindiny mechanisms, 401 nylon jackets, 402 anchor ears, 403 thick neck sets,
404 thin neck sets, 405 nylon bandages.
Specific embodiment
As described in Figure 1, it is a kind of shock-absorbing bridge support, includes to be vertically arranged between 2 bottom surface boss of bridge pier 1 and bridge
Elastic rubber column 3,3 one end of elastic rubber column contradict on 1 upper surface of bridge pier, the other end contradict under 2 bottom surface boss of bridge
It further include having that 3 one end of elastic rubber column is fixed on bridge pier 1 and 3 other end of elastic rubber column is fixed on bridge on bottom surface
Bindiny mechanism 4 on 2 bottom surface boss of beam, bindiny mechanism 4 include two nylon jackets 401 and at least three anchor ears 402, nylon jacket
401 include that the thick neck being socketed on 2 bottom surface boss outer peripheral surface of 1 outer peripheral surface of bridge pier or bridge covers 403 and is socketed in elastic rubber
Thin neck set 404 in rubber column gel column 3, the thick neck set 403 being socketed on 2 bottom surface boss outer peripheral surface of bridge are fixed on bridge 2 through anchor ear 402
On the boss of bottom surface, the thick neck set 403 being socketed on 1 outer peripheral surface of bridge pier is fixed on bridge pier 1 through anchor ear 402, and two are socketed in elasticity
Thin neck on rubber column 3 covers 404 free ends and overlaps to form double-layer structure in the middle part of elastic rubber column 3, and double-layer structure is through embracing
Hoop 402 is fixed in elastic rubber column 3, and each anchor ear 402 makes nylon jacket 401 in tight state, on two nylon jackets, 401 outer wall between
Every being equipped with more nylon bandages 405, each nylon bandage 405 is arranged centered on corresponding 401 central axis of nylon jacket in radioactivity.
Each nylon bandage 405 effectively improves 401 intensity of nylon jacket, and spiral winding is connected with more nylon on two nylon jackets, 401 inner wall
Bandage 405.The nylon bandage 405 of spiral winding setting improves nylon jacket 401 under the premise of guaranteeing 401 toughness of nylon jacket
Intensity, be all covered with antiskid elastic rubber layer on 402 inner wall of anchor ear contacted with nylon jacket 401, stayed between adjacent anchor ear 402
There is the gap convenient for the dislocation of 3 local radial of elastic rubber column.
When work, under normal circumstances, 3 supporting bridge 2 of elastic rubber column, nylon jacket 401 wraps up elastic rubber column 3, reduces
Elastic rubber column 3 is radial to be extended out, and promotes the intensity of elastic rubber column 3, while thick 403 package bridge pier 1 of neck set and 2 bottom surface of bridge are convex
Platform promotes 1 free end end of bridge pier and 2 bottom surface boss free end end intensity of bridge, avoids 1 free end end of bridge pier and bridge
2 bottom surfaces boss free end end are pressurized and chipping.
The present invention is not limited to the above embodiments, on the basis of technical solution disclosed by the invention, the skill of this field
For art personnel according to disclosed technology contents, one can be made to some of which technical characteristic by not needing creative labor
A little replacements and deformation, these replacements and deformation are within the scope of the invention.
