Description
Technical field
The utility model relates to bridge field, particularly relates to a kind of bridge dam.
Background technology
People are in the process of bridging beam at present, capital leaves a shrinkage joint, shrinkage joint refers to as preventing that building member is because climate temperature changes (heat rises, shrinkage), makes structure generation crack or destruction and along the vertical build joint arranging of suitable position of bridge length direction.It is on shrinkage joint, to cover an iron plate that current people adopt the way at covering shrinkage joint, then iron plate is fixed by screws on bridge, like this in the flexible process mistake of bridge, easily causes iron plate distortion.
In sum, for the defect of prior art, need especially a kind of dam.
Utility model content
The utility model, in order to solve the problem of prior art, provides a kind of dam.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of dam is provided, comprise that two are symmetricly set on middle " U " type geosynclinal block in shrinkage joint, " U " type geosynclinal block is fixedly connected with bridge by screw, one opposite face of " U " type geosynclinal block be provided with through hole, in two through hole, be arranged with the first slide block for sliding in through hole, the leading section of the first slide block is provided with baffle plate, above described shrinkage joint, be provided with the cover plate for hiding shrinkage joint, the bottom surface of cover plate is provided with the first groove, on two ledges of the first groove, be arranged with the second groove, the inside of the first groove is provided with the second slide block for sliding in the second groove, the first slide block is fixedly connected with by a plate with the rearward end of the second slide block.
In preferred embodiment of the utility model, described the second slide block is provided with multiple for reducing the roller of friction.
In preferred embodiment of the utility model, the two ends of described cover plate are arranged with a swash plate.
In preferred embodiment of the utility model, the diameter of described baffle plate is greater than the diameter of through hole.
The utility model compared with prior art, the advantage having is: a kind of dam described in the utility model, comprise that two are symmetricly set on middle " U " type geosynclinal block in shrinkage joint, " U " type geosynclinal block is fixedly connected with bridge by screw, one opposite face of " U " type geosynclinal block be provided with through hole, in two through hole, be arranged with the first slide block for sliding in through hole, the leading section of the first slide block is provided with baffle plate, above described shrinkage joint, be provided with the cover plate for hiding shrinkage joint, the bottom surface of cover plate is provided with the first groove, on two ledges of the first groove, be arranged with the second groove, the inside of the first groove is provided with the second slide block for sliding in the second groove, the first slide block is fixedly connected with by a plate with the rearward end of the second slide block.The utility model is in the process using, if the shrinkage joint of bridge constantly reduces, in the time being less than two first slide block spacings, " U " type geosynclinal block will promote junction plate and drive the second slide block action, can prevent so flexible cover plate distortion, and when shrinkage joint expands, when " U " type geosynclinal block will touch baffle plate, the first slide block will move under the drive of " U " type geosynclinal block, can prevent that so flexible cover plate disconnects.This is a kind of new technical scheme, is convenient to promote the use of.
