This invention relates to the field of safety protection technology and discloses a fall prevention device for a steel structure skylight opening. The device includes a supporting steel frame and a detachable supporting net. The supporting steel frame is installed on one side of the skylight opening, and the supporting net is movably connected to the lower end of the supporting steel frame. The supporting steel frame is an "I"-shaped steel frame, and the supporting net is connected to a retaining beam tie member, which is a concave shape. The horizontal steel below the "I" of the supporting steel frame is inserted into the retaining beam tie member. This invention has the advantages of allowing the supporting net to be lowered from the supporting steel frame, preventing it from being tightly attached to the skylight, thus increasing ventilation. Furthermore, the supporting net is detachable, making it easy to clean debris that falls onto the supporting net during wind.
