Description
Technical field
The utility model relates to a kind of bridge extension joint, especially relates to a kind of bridge seamless process stretching device based on reinforcing bar of putting more energy into.
Background technology
Bridge expanssion joint refers to the requirement for meeting bridge floor distortion, usually between two beam-ends, between beam-ends and abutment or in the articulated position of bridge, arranges shrinkage joint.And bridge extension joint be for make vehicle smoothly pass bridge floor and meet bridge floor distortion needs, at the device that expansion joint place is arranged.Stretching device is link the weakest in bridge construction, because stretching device directly bears the percussion of wheel cyclic reverse loading, even if there is very small out-of-flatness, this place will be made under carload effect to be severely affected effect, the most easily to be destroyed and the replacing that needs repairing.Slightly defect and deficiency in design or construction, will cause its early stage damage, this not only directly makes bridge passenger feel uncomfortable, lacks the sense of security, sometimes also can have influence on the normal use of bridge construction itself.Cause the general damaged reason of stretching device, except the magnitude of traffic flow increases, heavy vehicle increases (percussion obviously increases) outward, design, construction and maintenance aspect also can not be ignored, moreover bridge floor suddenlys change in expansion joint position rigidity, again under the repeated action of fast running vehicular load, its application life is had a strong impact on.Thus, bridge extension joint rapid wear problem is a great problem of highway communication always.To sum up, because expansion joint setting is at weak parts such as beam-ends, long term exposure in an atmosphere, environment for use is severe, and directly bear vehicle dynamic loading and percussion repeatedly, add the defect that design, construction and maintenance aspect exist, make the very easily damaged destruction also thereupon causing bridge floor and beam and slab structure of expansion gap device; Meanwhile, the inefficacy at shrinkage joint can increase vehicular impact power again, worsens driving conditions and bridge force-bearing, forms vicious circle.
Conventional stretching device is broadly divided into five large classes by mode of transfer force and construction features, that is: shearing, the modulus supporting type of dock, steel supporting type, building rubber compound and seamless expansion-contraction devices (containing bridge floor continuous structure).But there is the problems such as install inconvenience, stress performance and durability is poor, application life is shorter in existing bridge extension joint, therefore shrinkage joint rapid wear problem is not still solved well at present all to some extent.Best shrinkage joint is jointless, and thus bridge seamless process technology produces and paid close attention to, but existing highway bridge expansion joints without seals structure constructs mainly for abutment seamless process.At present, the research for bridge jointless construction is scarcely out of swaddling-clothes, and form of structure is less, and application is restricted.
