Description
Technical field
The present invention relates to bridge construction technical field, specifically a kind of can the rubber antidetonation comb plate stretching device of 3 D deformation for large span Flexible bridge.
Background technology
China is in large span flexible structure bridge and builds the epoch, and large span flexible structure bridge technology level or bridge construction quantitatively account for No. 1 in the world.Earthquake all over the world now occurs again and again, and earthquake intensity is also more and more stronger, and in order to tackle the disaster that earthquake brings, adopt multiple precautions against earthquakes to bridge construction, the bridge extension joint as the direct link of spanning also must be provided fortification against earthquakes.Comb plate stretching device also should have the function that " three-dimensional " is out of shape and movable comb tooth plate is raise-free.Comb plate stretching device so just can be made to follow flexible bridge structure together mutual compatible deformation, allow vehicle safety pass through bridge floor.
At present, the comb plate stretching device that China uses, some only has length travel function, when bridge rotates, often can occur that anchor bolt is broken, nut pulls.Although, also develop one " multidirectional " shift comb tooth plate stretching device now, add and longitudinally rotate or Plane Rotation function, but its deformation values is very little, it does not possess especially big lateral displacement function, and therefore it also can not meet the especially big transverse direction that produces when earthquake occurs and to swing requirement.
Prior art Problems existing is: the anchor bolt syndeton on movable comb tooth plate is unreasonable, and it affects two curb girder bodies to lateral displacement, vertical rotating with horizontally rotate.When movable comb tooth plate is not when establishing the beam body of rotating shaft side to produce vertical rotating, the tooth head of movable comb tooth plate can produce the phenomenon of nose, extreme influence traffic safety." multidirectional " shift comb tooth plate stretching device, in order to movable comb tooth plate nose thoroughly will be solved, also once movable comb tooth plate one being broken is two, be divided into comb portion and the movable comb tooth plate steel plate root of movable comb tooth plate, with cotter axle two altered and connect together, play free rotation, this free rotational structure, impact resistance is weak, poor rigidity.Bridge is because of the effect of wind lotus, beam body produces horizontal plane and rotates, because the anchor bolt on movable comb tooth plate is together with the anchoring of beam body, make movable comb tooth plate also follow this curb girder body and produce horizontal plane rotation together, the comb that movable comb tooth plate tooth head will promote fixed fingers plate produces reverse horizontal plane rotation, fracture to prevent the comb of fixed fingers plate, it is the vertical pinned connection of steel plate root of the comb portion of fixed fingers plate and fixed fingers plate, rotational problems solves, but its amount of spin is also atomic, because it is subject to the anchor bolt hole of fixed fingers plate and the clearance control of shank of bolt.
Summary of the invention
