PURPOSE: A cast standing apparatus of a roof slab is provided to stably and rigidly support the cast and after completing curing of concrete, to easily remove the cast by particular construction of the apparatus, and to obtain unevenness of the slab without loosing of the slab. CONSTITUTION: The apparatus comprises a sectional steel stand(110) having a length shorter than transverse length of a slab cast(10) and coupled with a truss(150) to prevent loosing or bending of the slab; a standing rod(130) contacting to the cast(10) and protruding toward both ends of the stand(110); yokes(180) to support longitudinally the ends of the stand(110); and a support device(200) to make the yokes to retain a constant level. The supporting device(200) has a supporting post(210), a channel(230) formed to seat the yokes(180), and at least one connections to hold the post(210) against shock generated during compacting process of concrete. The connection is coupled to a reinforcing bar at one end while at the other end, jointed to a clamp(265) mounted on the post(210) to form a connection bar.
