摘要

PROBLEM TO BE SOLVED: To provide a precast floor slab system being easily constructed from precast floor slabs and improving fatigue durability while preventing the precast floor slab thickness from increasing.;SOLUTION: A precast floor slab system 2 comprises: a pair of precast floor slabs 20, which are formed into tabular shape and disposed in an arrangement direction that intersects a thickness direction Z; and a connection part 25, which is disposed between and attached to the pair of precast floor slabs and integrates the pair of precast floor slabs by transmitting bending moment between the pair of precast floor slabs. The elastic modulus of the connection part is smaller than that of the pair of precast floor slabs and the tensile strength of the connection part is higher than that of the pair of precast floor slabs. The adhesive strength of the connection part to adhere to the pair of precast floor slabs is higher than the tensile strength of the pair of precast floor slabs.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2017,JPO&INPIT
