Construction method of prestressed concrete floor slab and floor slab using prestressed concrete floor slab

摘要

To provide a pre-stressed concrete floor slab capable of facilitating the improvement of earthquake resistance of the entire bridge by reducing the weight of the floor slab.SOLUTION: A pre-stressed concrete floor slab 1 using fiber reinforcement concrete, comprising a plate portion 2, and a lattice-like rib 3 composed of a vertical rib 31 and a lateral rib 32 formed on the underside of the plate portion 2, in which pre-stress is introduced to the vertical rib 31 by post-tensioning system, and pre-stress is introduced to the lateral rib 32 by pretension system.SELECTED DRAWING: Figure 1
