<p>]Provided is an apparatus for lifting a temporary stand including a profile5 installed at a side opposite to an outer wall of a structure and having a plurality of latches disposed at predetermined intervals, including a pair of left and right guide frames having guide grooves formed in a direction perpendicular to a lift direction of the profile, support frames configured to support the guide frames, and facing and spaced apart from each other, guide channels obliquely formed in the support frames,to and configured to provide a moving path of a stopper such that the stopper is raised along an oblique path by the latch when the profile is raised, and the stopper is lowered due to its own weight after the latch passes, the stopper installed between the support frames such that the stopper contacts the latch to move straight upward along the guide channel when the profile moves upward, and the stopper is latched by the latch, when15 the profile is lowered, to support a lower portion of the latch to raise the profile, and a pair of left and right guide arms configured to slide along the guide grooves formed in the guide frames to be opened or closed. Therefore, the temporary stand can be safely and easily raised and lowered to a desired height position.Fig. I</p> |
