The present invention relates to a pi-type PC slab and a composite method using the same, wherein the PC slab integrally comprises: an upper plate having buried connection bars formed at the upper side thereof at regular distances; webs downwardly formed at both end portions of the upper plate; and lower plates formed to outwardly protrude from the bottom portions of the webs, wherein the lower plate has: a upper flange protruding from the upper side of the outer end portion thereof; and a lower flange protruding from the upper side of the outer end portion thereof and more protrusive than the upper flange. According to the present invention, the pi-type PC slab is shaped into a pi of which the lower side is opened so that a structure applied with the PC slab can be lightened; the structure can be easily constructed because topping concrete is placed on the PC slab which is simply mounted; tendons can be easily arranged because the tendons are arranged in a space between the PC slabs; the upper plates and the lower plates simultaneously function as shear keys when the PC slabs are mutually coupled in the width directions thereof so that a composite action between the PC slabs and precast concrete at the upper sides thereof can be strengthened and cracks between the PC slabs can be prevented, wherein the cracks are due to loads applied on the upper sides of the PC slabs. |
