<p>The present invention pertains to a structure of a slab and a construction method therefor, wherein: wherein a steel wire is mounted and pre-stress is introduced so as to increase the bending rigidity of the slab, and a plurality of slabs having beams interposed therebetween is continuously formed and resistance for a negative moment applied to a point is improved so as to reduce cracks and decrease the deflection of the slab. The PC slab which is mounted on a half PC beam wherein concrete is simultaneously poured into the PC slab and the remaining portion of the half PC beam such that the beam and the slab are integrally coupled, comprises: an upper plate on which a longitudinal reinforcement bar and a traversal reinforcement bar are secured; a pair of side plates folded downwards at both side ends of the upper plate; and a pair of lower plates horizontally folded outwards from each of the side plates so as to be placed on the top surface of the half PC beam, wherein the slab forms a single module with the above elements, and the outer surfaces of the side plates are formed with at least one or more mounting grooves for a fixing means which fix the position of the steel wires.</p> |
