[0002] The edge and hole safety protection of the construction site is one of the important measures to ensure the safety of workers and prevent accidents during construction. During the bridge construction phase, when the beam body is erected or cast-in-place is completed, but before the reinforcement concrete guardrail pouring is carried out, the bridge construction is a high-altitude operation, and the bridge protection device needs to be set up to prevent objects from falling or people from falling.

[0003] The edge operation protection fence should be composed of a fence body, a support, a connecting piece, and a fixing piece. The fence body is the main part of the edge protection fence, which is composed of a horizontal rod and a vertical rod. The support is a supporting structure between the fence body and the ground or floor, which fixes the fence body and prevents it from shaking or tilting. The connecting piece connects the fence body and the support together. The fixing piece fixes the edge protection fence to the ground or floor. The edge protection fence is widely used in high-altitude operation sites such as construction, bridge construction, skylight installation, and maintenance.
