<p>The present invention relates to a ladder for a gang form with an opening to mold an opening such as a balcony window in the outer wall of a building, which is mounted on the gang form and which allows a worker to safely go up and down between a slab and a working foothold. According to the present invention, a ladder for a gang form comprises: two columns (10) having multiple footholds (20) arranged therebetween; a foldable link (30) of which one end is mounted on the middles of the columns (10) and the other end is mounted on a vertical support (120) exposed through the opening (110) of the gang form (100); and leveling foot units (40) formed on the bottoms of the columns (10), and having adjustable heights, wherein the columns (10) have tops held on the working foothold (130) of the gang form (100). Therefore, according to the present invention, when the columns (10) are arranged to be tilted, the foldable link (30) is capable of being unfolded to allow a worker to step on the footholds (20) and to safely go up and down between a slab (140) and the working foothold (130) of the gang form. In addition, according to the present invention, when the columns (10) are erected vertically, the foldable link (30) is capable of being folded, so the vertically erected columns (10) can adhere to the vertical support (120) of the gang form (100).</p> |
