[0002] A bridge is a structure used for railways, roads, channels, pipelines, etc. to cross rivers, valleys or other transportation lines. It is generally built on rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. When constructing a bridge, in order to improve its safety, it is necessary to install guardrails at the edge of the bridge through a connecting structure; the connecting structure of the existing bridge guardrails has certain disadvantages when used. When installing the bridge, it is either installed only by bolts, which has poor stability and safety performance, or it is an integrated structure and poured with concrete. This method is firmly installed, but when the guardrail is damaged and needs maintenance, it is cumbersome to disassemble. For this reason, we propose a connecting structure for a bridge guardrail.
