The present invention relates to a prefabricated safety ladder for a formwork, and has purposes for providing a passage in which a worker safely moves above the formwork, allowing the worker to easily handle the safety ladder by installing the ladder at the formwork in a construction site in order to reduce the volume of the formwork and the ladder, and sets the safety ladder at a position suitable for a structure and the construction site. The safety ladder according to the present invention comprises: a ladder part (10) consisting of a pair of vertical rods (11) and multiple footholds (12) formed into multiple stages between the vertical rods; a safety guard part (20) coupled to the ladder part and providing the peripheral part of the ladder part with the passage for the worker; and a fixing unit (30) to which the ladder part is detachably coupled and detachably fixed to one side of the formwork. The safety ladder is detachably installed at the formwork. The fixing unit comprises a formwork fixing part and at least one clamp (34) for fixing the safety ladder, wherein the formwork fixing part includes: an upper hook part (31) fixed and hooked on the upper side of a reinforcing member installed at one side of the formwork; a lower hook part (32) connected to the upper hook part, able to be lifted, and inserted into the lower part of the reinforcing member; and a locker (33) fixing the lower hook part to the upper hook part, and the clamp (34) is installed at the formwork fixing part and is fixed with the ladder part. |
