Abstract

PURPOSE: To prevent the occurrence of contraction cracks and reduce the quantity of reinforcing bars by arranging PC steel materials with tension in contiguity with the lower surface of a floor plate and in parallel with the upper surface of the floor plate among pillars in the floor plate of a taper slab structure comprising an inverted pyramid having a pillar core as an apex connected thereto. CONSTITUTION: A floor board 1 of a taper slab structure has an inverted pyramid having a pillar 2 core as an apex and the upper surface of the floor plate 1 as a bottom surface, and horizontal PC steel materials 4 being in contiguity with the lower surface of the floor board 1 and in parallel with the upper surface of the floor board 1 are arranged among inside surfaces of the pillars 2, both ends of the PC steel materials 4 are respectively anchored on the outside surface of the pillars. In this fashion, since prestress can be introduced within the floor plate 1, contraction cracks generated on the floor plate 1 can be prevented, and also a bending moment negating a bending moment generated on the floor plate 1 is generated on the pillars 2, thus reducing the quantity of reinforcing bars used in the floor board 1.
