Description

Technical Field

[0001] The utility model relates to the technical field of guardrails, in particular to a guardrail for a pedestrian bridge. Background Art

[0002] Pedestrian bridges, also known as overpasses, are buildings that cross roads in areas with dense traffic and pedestrian flow to solve the problem of pedestrian crossing and the separation of pedestrians and vehicles. By three-dimensionally separating road traffic flow, pedestrian bridges can better solve the traffic congestion problem caused by the plane intersection of traffic flow. Therefore, they play a very important role in urban traffic and are also important buildings in modern urban spaces. In an environment where pedestrians walk at high altitudes, they are prone to accidents such as falls, and the presence of railings can effectively reduce the risk of these accidents. Especially in the case of large pedestrian flow and frequent pedestrian traffic, the role of railings is more obvious.

[0003] In the prior art, the guardrail of the pedestrian bridge is mainly composed of columns, beams, vertical rods and connecting parts, which play a role of stability and protection. Pedestrians on the pedestrian bridge are prone to produce beverage bottles, glass jars, milk cartons, etc. after stopping to eat. After throwing them on the ground, they are easily rolled down to the bottom of the pedestrian bridge with the wind. When encountering passing vehicles, they are easy to hit the outer surface of the vehicle and cause damage. At the same time, it is extremely difficult for cleaning personnel to pick up between passing vehicles. Therefore, we propose a guardrail for a pedestrian bridge to solve the above problems.
