[0002] A viaduct is a type of bridge that generally refers to a bridge that crosses a deep ravine instead of a high embankment, as well as a bridge that crosses a road in an urban area. It is supported by high-supported towers or pillars. However, for roads passing under the viaduct, a height limit frame lower than the bottom of the viaduct is usually set to prevent over-limit vehicles from colliding with the bridge body.
[0003] In the prior art, for example, Chinese patent number: CN215758678U discloses a bracket for height limit signs for bridge engineering, including a substrate, the number of which is two, the centers of the tops of the two substrates are fixedly connected with springs, the front and rear ends of the two sides of the top of the substrate are fixedly connected with a top plate, the top of the top plate is fixedly connected with a support plate, the top of the support plate is fixedly connected with a functional frame, and the front and rear ends of the functional frame are fixedly connected with a luminous film.
