Background technology
Bridge expanssion joint refers to the requirement for meeting bridge floor distortion, conventionally between two beam-ends, shrinkage joint is set between beam-ends and abutment or in the articulated position of bridge.And bridge extension joint is for making vehicle steadily by bridge floor and meet the needs of bridge floor distortion, the device arranging in expansion joint place.Stretching device is link the weakest in bridge construction, the percussion of directly bearing wheel cyclic reverse loading due to stretching device, even if there is very small out-of-flatness, under carload effect, will make this place be severely affected effect, the most easily be destroyed and the replacing that needs repairing.Slightly defect and deficiency in design or construction, will cause its early stage damage, and 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 outside (percussion obviously increases), design, construction and maintenance aspect also can not be ignored, moreover bridge floor suddenlys change at shrinkage joint position stiffness, under the repeated action of fast running vehicular load, had a strong impact on its application life again.Thereby 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 is in 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 destruction that expansion gap device is very easily damaged and cause bridge floor and beam and slab structure thereupon; Meanwhile, the inefficacy at shrinkage joint can increase again vehicular impact power, worsens driving situation 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 the problems such as existing bridge extension joint all exists installation inconvenience, stress performance to some extent and durability is poor, application life is shorter, therefore shrinkage joint rapid wear problem is not still solved well at present.Best shrinkage joint is jointless, thereby bridge seamless process technology produces and paid close attention to, but the seamless expansion joint structure of existing bridge is constructed mainly for abutment seamless process.At present, be scarcely out of swaddling-clothes for the research of bridge jointless construction, form of structure is less, and application is restricted.
