Description

Technical Field

[0001] The utility model relates to the technical field of steel structure bridges, and particularly relates to a spliced beam of a steel structure. Background Art

[0002] A steel structure bridge is a bridge whose main load-bearing structure is made of steel, that is, a steel structure bridge or a steel bridge. The main design concept is to assemble the least variety of unit components into an assembled steel bridge that can bear various loads and different spans, and only requires a general medium-sized truck for transportation. In special cases, it can be completely built by manpower, with the advantages of convenient transportation, easy construction, and strong adaptability, and is widely used. During use, most steel structure spliced bridges use bolts to connect adjacent bridges. However, since the bolts are exposed outdoors for a long time, they are prone to rust, looseness, and falling off due to wind, sun, and rain erosion, further affecting the stability of the steel structure spliced bridge. In the technical solution disclosed in the patent with the patent publication number CN219886539U and the patent name "A Steel Structure Spliced Bridge", protective cylinders are provided at both ends of the threaded rod to protect the exposed ends of the threaded rod. However, the connection between the first bridge and the second bridge is not protected accordingly. During use, rainwater may also enter from the connection between the two, affecting the service life of the threaded rod and the stability of the connection between the first bridge and the second bridge.
