PURPOSE: A safety door for the scaffold board of a gang form is provided to prevent a part of a worker's body from being jammed between a safety door and scaffold board by adjusting the opening and closing speed of the safety door. CONSTITUTION: A safety door (100) for the scaffold board of a gang form comprises a first door frame (110) and a shock-absorbing device. The first door frame is joined to one side of a working path (30) to rotate around a first hinge shaft (111). The shock-absorbing device suppresses the closing speed of the safety door using extension and contraction actions of a shock absorber into the first door frame. The shock absorber comprises a shock absorber body and a rod. The shock absorber is embedded into a central frame (113) when the safety door is closed. |
