PURPOSE: A T-shaped PC slab is provided to reduce floor height by removing dead space under a beam and to improve productivity and economical efficiency. CONSTITUTION: The T-shaped PC slab comprises: a dab end(20) formed in the shape of a projection as a flange whose end(22) is thicker than the center(23); and a slab end formed by folding one of webs or many webs in an L-shape on the lower part of a flange. The construction method of a structure using an improved T-shaped PC slab comprises the steps of installing many PC columns vertically, installing many wide rectangular PC beams or inverse T-shaped PC beams perpendicularly on the top of the PC columns, installing many T-shaped PC slabs(9,13) between the PC beam and the PC beam, and arranging upper reinforcing bars on the PC columns, the PC beams and the T-shaped PC slabs(9,13) and placing slab concrete.
