CONSTRUCTION METHOD FOR SLAB, SHEAR REINFORCEMENT, AND CONCRETE BEAM STRUCTURE

摘要

PROBLEM TO BE SOLVED: To achieve non-shoring construction of an overhang part of a half-precast slab.;SOLUTION: A half-precast slab 4 is used which includes a main-body part 41 and overhang parts 42, a truss reinforcement 44 buried in those main-body part and overhang parts to be exposed on their top surfaces, and slab lower end reinforcements 43 exposed between the main-body part and overhang parts. Both side parts of the main-body part 41 and base-end parts of the overhang parts 42 are placed on beams 3 which are installed in parallel and each has lower shearing reinforcements 31 exposed on its upper surface. After a slab upper end reinforcement 46 and main reinforcements 32 of the beams 3 are arranged at upper part of the lower shearing reinforcements 31 and a part of the truss reinforcement 44 from above between the main-body part and the overhang parts, and an upper shearing reinforcement 6 in a shape over the upper parts of the lower shearing reinforcements 31 and the part of the slab lower end reinforcement 43 is arranged, concrete is cast such that the lower shearing reinforcements 31, the truss reinforcement 44, the slab lower end reinforcements 43, the slab upper end reinforcement 46, the main reinforcements 32 of the beams 3, and the upper shearing reinforcement 6 are buried.;COPYRIGHT: (C)2013,JPO&INPIT
