Description

Technical Field

[0001] The utility model relates to the technical field of bridge expansion joints, in particular to an expansion joint device with a non-motor vehicle anti-sinking function. Background Art

[0002] A bridge expansion joint refers to a joint that is set between two beam ends, between a beam end and abutments, or at the hinged position of a bridge to meet the requirements of bridge deck deformation.

[0003] After searching, the patent number is CN212956114U, and the name is a utility model of a bridge expansion joint, which includes a first bridge body and a second bridge body arranged relatively to each other. Through research and analysis, it is found that although it can reduce the fluctuation of the expansion joint in the vertical direction during use and improve the service life of the bridge, etc., it still has the following disadvantages to a certain extent.

[0004] For example, the expansion joint does not have an anti-sinking function. During use, due to the large spacing between the comb teeth, the tires of some non-motor vehicles will get stuck in the gaps between the comb teeth during driving, thus creating a safety hazard. At the same time, impurities such as dust and stones will also accumulate inside the comb teeth. In order to solve the above technical problems, we have designed an expansion joint device with an anti-sinking function for non-motor vehicles. Utility Model Content

The right side of the protective plate extends to the inner cavity of the second rectangular groove. At this time, the first comb teeth and the second comb teeth are located at the bottom of the protective plate. Under the action of the protective plate, non-motor vehicles can be protected to prevent the tires from being stuck in the gaps of the comb teeth.

[0013] 2. The utility model has the advantage of intercepting function through the cooperation of the cylinder, the intercepting rod, the first groove and the second groove. When the bridge needs to be maintained or an emergency occurs, the user loosens the limit bolt with a wrench, then moves the intercepting rod out of the cylinder with the pull rod, and then tightens the limit bolt. At this time, the intercepting rod is higher than the two steel plates, and the surface of the intercepting rod is pasted with a reflective strip, so that passing vehicles can be intercepted more conveniently.
