PURPOSE: To simplify construction work for a cantilever slab by standing on a mold a precast concrete hand rail having the anchoring portion of a reinforcing bar protruded from the lower portion thereof, and disposing reinforcing bars of a slab portion, and then placing slab concrete.
CONSTITUTION: After the mold K of a slab portion 2 is assembled on a support P, a hand rail 1 is hanged by a crane using a hanging hook screwed into a nut anchor 4 provided at the upper end portion of a precast concrete hand rail 1 having the anchoring portion 3a of a reinforcing bar 3 protruded from the lower portion thereof. The hand rail 1 is then stood on the end portion of the mold K and other nut anchors 4 are attached to the hand rail 1 and metal fittings M are attached thereto. A wall support is provided between the metal fittings M and the mold K so as to support the hand rail 1. A channeled mold 9 is supported by a support metal fitting 10 using a nut anchor 5 located below the mold 9. After the slab portion 2 is reinforced by reinforcing bars, slab concrete is placed.
