PC Half Depth Concrete Deck Panel With Precast Rib And Construction Method Using Therof

摘要

The present invention relates to a half PC slab having an upper protruding rib and a construction method thereof, and more particularly, set back at both ends of a branch portion of a lower PC panel for a predetermined period, respectively, and precast the ribs protruding upwards integrally with the lower PC panel By prefabricating as a member, it facilitates the reinforcement of moment-resisting reinforcing bars for beams that are placed in parallel with the direction of the beams supporting the half PC slab in the section on both sides of the half PC slab, so that the Half with upper protruding ribs that can be uniformly placed at the top and bottom to resist negative moment, and can secure integrity at both ends of the point between the precast concrete and cast-in-place concrete of the half PC slab and strengthen the shear composition It relates to a PC slab and its construction method. A preferred embodiment of the present invention includes a lower PC panel formed of precast concrete of a certain size; an upper protruding rib integrally formed with the lower PC panel in the longitudinal direction so as to protrude upward in a section except for some sections from both longitudinal ends of the lower PC panel to the inside in the longitudinal direction; a lower circumferential reinforcing bar formed in the same length as the lower PC panel or reinforced in the longitudinal direction of the lower PC panel so as to protrude a predetermined length from both longitudinal ends of the lower PC panel; The lower sub-direction reinforcing bar is reinforced in the width direction of the lower PC panel so as to intersect the lower circumferential reinforcing bar, and both ends are configured to protrude a predetermined length to both sides in the width direction of the lower PC panel.
