Description
Technical field
The invention belongs to bridge structure or technical field of buildings, is related to a kind of bridge pad with antidumping function.
Background technology
With the fast development of highway, city expressway and city intersection, the structural shape of bridge shows various
The development trend of change, there is substantial amounts of small curve bridge and ramp bridge.These bridges are generally narrower, and sweep is smaller, and one
There is larger unbalance loading in denier, and bridge easily occurs and topples phenomenon.In recent years, more cause bridges have occurred unbalance loading occur and bridge occurs
The major accident toppled or caved in.
At present, the commonly used laminated rubber bearing of domestic highway bridge, pot rubber bearing and spherical bearing are as highway
The supporting construction of bridge, these type supports are respectively flexible to rotation and do not possess tension, the ability of antidumping.It is common for application
The bridge and ramp bridge of the small curve of bridge pad, once larger unbalance loading occurs, it is higher that the probability that bridge topples occurs.At present,
Possess and draw the bearing for carrying function mainly to have tension and compression pot bearing and central draw bar type spherical bearing, these bearings can be born vertically
Pressure and can bears upward pulling force and horizontal load, substantially meets the requirement that bridge uses bearing function.But benzvalene form tension and compression
Bearing is easy to aging using rubber as material of main part, and service life is short.Tension and compression ball-type tension compression bearing, due to using spherical structure
Middle seat board, rotation is excessively flexible, once bridge unbalance loading is excessive, resistance to capsizing is weaker.
Cross-saddle single-track traffic is a kind of new model of modern city fast railway multilevel traffic, with noise is low, climbs
Slope ability is strong, radius of turn is small, rapid and convenient, takes up an area less, low cost, is not limited by landform and many excellent beneficial to environmental protection etc.
Point, it is a new trend of future city track traffic development.Straddle type rail transit track girder removes as two-way deflection component
Bear train vertical load and lateral load（Centrifugal force, wind-force etc.）Effect is outer, also subject to larger lateral torsion and horizontal torsion
Torque, straddle-type rail beam bearing, which removes to have, bears vertical load, horizontal loading and adaptation beam-ends deformation（Displacement, rotation）
Outside, should also resistance draws the functions such as load, torsion load and overturn-preventing.
Although existing PC track girders cast steel supporter functionally disclosure satisfy that the use of straddle-seat type single traffic rail beam will
Ask, but in actual applications there is also some shortcomings, it is specific as follows：1）The main power transmission position of bearing is linear contact lay（Such as hinge and
Cam position）, it is unfavorable for the overall uniform force of seat structure.2）Each part of bearing is the linear contact lay friction of " steel-steel "
Pair, effectiveness in vibration suppression is poor, requires high to the combination property of contact site material, material property control, surface treatment and part are added
The requirement of work precision is higher.
The either curve bridge of highway or straddle type rail transit bridge, require that bearing has anti-pulling and resisted and incline
The function of covering.
