Description
Technical Field
The utility model relates to an expansion joint for bridge, specific comb tooth type expansion joint that possesses shock-absorbing function and has and fall the noise that makes an uproar produced in order to reduce the vehicle and go out of date that says so.
Background
For satisfying the demand that the multidirectional displacement of bridge structures, also consider for driving the travelling comfort simultaneously, more and more bridges adopt broach type expansion joint, and its proportion that occupies the expansion joint market also is the trend that rises year by year. However, the comb expansion joints of the current mainstream are easy to cause the loosening damage of the anchoring nuts. Moreover, the transverse displacement between the beam bodies is usually realized through the gaps of the comb teeth, the displacement range is extremely small, and the expansion joint is difficult to stretch or even cause the comb teeth to break easily because foreign matters are clamped into the gaps between the comb teeth. In addition, the occurrence of vertical displacement between the beams can cause irreversible damage to the structure of the seam.
At present the initial form of the broach expansion joint disease of mainstream is mostly that the nut is not hard up, the broach card dies, and then develops into the pinion rack and drops, the broach fracture. The nut becomes flexible except the factor in the aspect of the construction, and its root cause is that its self structure has certain problem, mainly because the single-ended anchor of movable tooth plate, and do not have the resiliency, so after receiving load impact, the single-ended anchor of movable tooth plate leads to the bolt at stiff end to bear great bending stress because the pinion rack is bent, very easily causes the bolt under the repeated action of vehicle load to bear great bending stress
Self vibration, along with the accumulation of vibration energy and number of times, the bolt can appear small deformation, causes stress relaxation, makes the bolt pretightning force reduce, and then takes place the not hard up phenomenon of early failure of bolt to lead to the noise problem of driving a vehicle.
In conclusion, how to improve the shock absorption and impact resistance capability of the comb tooth expansion joint has positive significance for prolonging the service life of the comb tooth expansion joint.
