Technical Field

[0001] This utility model relates to the field of guardrail structure technology, and in particular to a collision protection guardrail structure for mixed-traffic bridges. Background Technology

[0002] In bridge environments where pedestrians, non-motorized vehicles, and motorized vehicles share the same traffic, guardrails need to simultaneously meet multiple requirements, including vehicle collision protection and pedestrian safety. Traditional bridge guardrails often struggle to address these issues. While some guardrails can withstand vehicle impacts, they may create walkable surfaces, posing a safety hazard for pedestrians to climb. Some guardrails prioritize pedestrian safety but lack sufficient impact resistance. Furthermore, while some guardrails meet the height requirements for non-motorized vehicle lanes, their top crossbeams and handrails are too high, failing to provide adequate support and balance for pedestrians. Therefore, there is an urgent need for a comprehensive bridge crash barrier structure that can effectively solve these problems. Utility Model Content

[0013] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0014] A collision protection railing structure for a mixed-traffic bridge includes a collision protection structure composed of multiple sets of steel columns 1 and multiple sets of steel beams 2. The collision protection structure is covered with an aluminum alloy perforated plate 3. The multiple sets of steel beams 2 are welded at equal intervals to one side of the steel columns 1. A stainless steel handrail 4 is provided on the side of the steel column 1 near the steel beams 2. The stainless steel handrail 4 is located between two sets of steel beams 2 and near the top of the steel column 1. A cover plate 12 is provided on the top of the steel column 1.

[0015] The anti-collision structure, composed of steel columns 1 and steel beams 2, uses multiple sets of steel beams 2 welded at equal intervals to evenly distribute the impact force of motor vehicles, improving overall anti-collision performance and effectively preventing motor vehicles from running off the bridge. The outer aluminum alloy perforated plate 3 covers the connection gap between the steel beams 2 and the steel columns 1, preventing the formation of a walkable surface and preventing pedestrians from climbing. At the same time, the perforated plate can be designed with patterns to enhance the bridge's aesthetics. The stainless steel handrail 4 is set between the two sets of steel beams 2 and near the top, with a height adapted to the support needs of pedestrians, providing balance and support for pedestrians and improving walking comfort. The cover plate 12 on the top of the steel column 1 can cover the top structure of the steel column 1, which not only beautifies the appearance but also prevents rainwater and debris from entering the column and causing corrosion. Taking into account safety, practicality, and aesthetics, it has significant practical value.

[0016] As a possible implementation of this solution, preferably, it also includes a railing base 6 and a main beam 5, wherein the railing base 6 is disposed on the main beam 5, and multiple sets of the steel columns 1 are disposed at equal intervals on the railing base 6.

[0017] The railing base 6 connects the steel column 1 to the main beam 5. Multiple sets of steel columns 1 are evenly spaced on the railing base 6, which makes the steel column 1 more evenly stressed, enhances the connection stability between the railing and the main body of the bridge, and avoids excessive stress on a single steel column 1, which could lead to tilting or damage.

[0018] As a possible implementation of this solution, preferably, a steel plate 11 is pre-embedded inside the railing base 6, the steel plate 11 is located at the bottom of the steel column 1, and several sets of reinforcing bars are welded to the bottom of the steel plate 11.

[0019] The embedded steel plate 11 in the railing base 6 and the steel bars welded to the bottom can increase the connection area and friction between the steel column 1 and the railing base 6, and transfer the load borne by the steel column 1 to the main beam 5, further improving the overall anti-overturning ability and structural stability of the railing. As a possible implementation of this solution, preferably, the steel beam 2 is composed of multiple sets of connecting beams, which are connected by connecting sleeves 21, with both ends of the connecting sleeves 21 passing through the connecting beams to form the steel beam 2.

[0020] The connecting sleeve 21 connects multiple sets of connecting beams to form a steel crossbeam 2, which facilitates the segmented processing, transportation and installation of the steel crossbeam 2. At the same time, the connecting sleeve 21 can ensure the coaxiality between the connecting beams and improve the overall rigidity of the steel crossbeam 2. As a possible implementation of this solution, preferably, one end of the connecting sleeve 21 is inserted into the connecting beam and fixedly connected by bolts 22, and one end of the connecting sleeve 21 is a free end that is inserted into the connecting beam at the other end.

[0021] One end of the connecting sleeve 21 is fixed with bolt 22, and the other end is freely inserted into the connecting beam. This not only ensures the reliability of the connection, but also provides space for the expansion and contraction of the steel beam 2 due to temperature changes, so as to avoid deformation or damage to the structure due to thermal expansion and contraction.

[0022] As a possible implementation of this solution, preferably, the connection between the connecting sleeve 21 and the connecting beam is sealed with waterproof putty 7. The waterproof putty 7 seals the connection between the connecting sleeve 21 and the connecting beam, which can prevent rainwater, dust and other substances from entering the connection part, prevent the bolt 22 and the connecting sleeve 21 from rusting, and extend the service life of the guardrail.

[0023] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. This utility model is not limited to the specific embodiments disclosed herein; other embodiments falling within the scope of the claims of this application are all within the protection scope of this utility model.
