[0002] A bridge is a structure used to cross obstacles, which serves the purpose of connection and passage. It can facilitate the passage of people and vehicles between different locations. It eliminates geographical barriers, connects road networks, and promotes the flow of people and goods. The steel guardrail of the bridge can separate the moving vehicles from the edge of the bridge or the potential dangerous area below, prevent the vehicle from accidentally running off the bridge deck, and protect the safety of vehicles and pedestrians.

When a vehicle accidentally collides, it cannot fully reduce the impact force, which may cause damage to the vehicle and the guardrail. At the same time, it fails to effectively improve the strength of the steel structure and cannot issue an early warning when the guardrail is hit to alert the vehicle behind to a collision.

[0004] In order to solve the above problems, this application proposes a reinforced bridge steel structure. Utility Model Content

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0022] like Figure 1-3 As shown, a reinforced bridge steel structure proposed by the utility model includes a guardrail frame 1;

[0023] In this embodiment, a plurality of rope steering members 2 are connected to the guardrail frame 1 at intervals, and a plurality of strips 3 are installed on the outer side of the guardrail frame 1. The plurality of strips 3 correspond to the plurality of rope steering members 2 respectively. A slide groove is provided in the strip 3, and an elastic buffer 4 and a limit pressure sensor 5 for limiting the elastic buffer 4 are provided in the slide groove. One end of the plurality of rope steering members 2 are respectively connected to the plurality of elastic buffers 4.

[0024] In this embodiment, the guardrail frame 1 includes a base 101 , columns 102 and railings 103 . There are a plurality of columns 102 , which are respectively installed around the top of the base 101 , and the railings 103 are installed on the plurality of columns 102 .

[0025] In this embodiment, the pull rope steering member 2 includes a steel wire rope 21 and a protective tube 22. One end of a plurality of steel wire ropes 21 is connected to the base 101 at intervals. A plurality of through openings are provided on the handrail 103. The other ends of the plurality of steel wire ropes 21 pass through the plurality of openings and are connected to the corresponding elastic buffer 4. The protective tube 22 is sleeved on the steel wire rope 21 and is located between the base 101 and the handrail 103. The elastic buffer 4 includes a slider 41, a connecting rod 42 and a spring 43. The slider 41 is slidably arranged in the slide groove. The connecting rod 42 is installed on the side of the slider 41. The bar 3 is installed on the outside of the base 101. A through hole connected to the slide groove is provided at one end of the bar 3 away from the base 101. The end of the connecting rod 42 away from the slider 41 slides through the through hole.
