Description
Technical field
The present invention relates to bridge technology field, is specifically a kind of overload surrender formula wind-resistant support.
Background technology
Wind-resistant support is generally used for stayed-cable bridge or suspension bridge, between tower and bridge, on the one hand transmits horizontal water
Flat power, plays fixed bridge beam action；On the other hand bridge is not allowed to consolidate with tower.Wind-resistant support be arranged on the tower of bridge and bridge it
Between, typically could install in the later stage, as construction has error, and existing backed installation dimension is often fixed, it is impossible to
Adapt to error present in construction.
For the less area of earthquake intensity, bridge structure readily satisfies the transmission of horizontal force.But for high-intensity earthquake
Region, the transmission met by power, a kind of scheme are increase physical dimensions, i.e. " hard anti-", but this scheme needs to roll up bridge
The manufacturing cost of beam；Another kind of scheme is the method for designing using damper, i.e. " soft anti-", and this scheme greatly can drop
Low antidetonation cost.
Overload surrender formula wind-resistant support of the present invention is specially developed for damper design
Kind of wind-resistant support, is primarily adapted for use in high intensity Zone, using subtracting, the stayed-cable bridge of shock design or suspension bridge.
The content of the invention
The invention provides a kind of overload surrender formula wind-resistant support, is primarily adapted for use in high intensity Zone, it is existing to overcome
The installation dimension for having bearing present in technology does not adapt to the problem of error present in construction.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is summarized as follows：
A kind of overload surrender formula wind-resistant support, including the steel basin, bearing plate, middle steel plate for setting gradually from top to bottom, props up
Support adjustment ring and plane steel plate, the steel basin, interfixes between bearing plate, middle steel plate, and the middle steel plate is set in
Support in adjustment ring, and middle steel plate is moved up and down along support adjustment ring, the joint face for supporting adjustment ring and plane steel plate
On be connected with plane wear-resistant slide plate, support the inwall of adjustment ring to be provided with female thread, the middle steel plate is externally provided with corresponding external screw thread；
Under nominal situation or under E1 earthquake operating modes, adjust middle steel plate and support the position of adjustment ring, the height gauge of electrodeless adjustment bearing
It is very little, until cause bearing to reach the purpose for holding out against tower and bridge, due to the setting at middle steel plate and support adjustment ring so that i.e.
Construction is made to there is error, the height dimension of bearing also can adapt to, the strong adaptability of the bearing, so as to overcome in prior art
The installation dimension of the bearing of presence does not adapt to the problem of error present in construction.
More excellent, the steel basin is provided with copper sealing ring with the junction of bearing plate side wall.
More excellent, the material of the bearing plate is rubber or polyurethane.
More excellent, the upper end of the middle steel plate is provided with projection, is provided with that middle steel plate is stuck below the steel basin
Pressure strip, the pressure strip Jing pressure strips are bolted on steel basin.
More excellent, the external screw thread of the female thread and middle steel plate for supporting adjustment ring is trapezoidal thread, E2 earthquakes
Under operating mode, trapezoidal thread transships and is cut off so that bearing is carrying direction surrender, so as to mutually separate between tower and bridge, rises
To the effect of shock insulation, and bridge is increased in horizontal activity space, so as to change the vibration period of total, reach
The purpose of damping, plays a part of overload protection bridge or other fabric structures.
Compared with prior art, the beneficial effect produced by the present invention：
(1) engagement thread is adopted, can freely adjusts height of support size, be adapted to the bearing produced because of reasons such as constructions
Installing space error, plays the effect of holding out against, and the installation dimension for solving bearing present in prior art is not adapted in construction
The problem of the error of presence；
(2), under E2 earthquakes operating mode, trapezoidal thread is sheared destruction, bearing carrying direction surrender, so as to tower and bridge it
Between mutually separate, play the effect of shock insulation, and increase bridge in horizontal activity space, change the vibration week of total
Phase, so as to reach damping purpose, play a part of overload protection bridge or other fabric structures.
