FLOOR STRUCTURE USING PRECAST COMPOSITE SLAB, WIDENING PLATE, AND PRECAST COMPOSITE SLAB, AND BUILDING

摘要

PROBLEM TO BE SOLVED: To provide a floor structure and a building using a precast composite slab, a plate for widening, and a precast composite slab excellent in workability and economy which is possible to cope smoothly with floors such as multi-dwelling houses that require through-holes for equipment piping by applying concrete to the deck plate for synthetic slabs and putting in concrete to realize a precast synthetic slab.;SOLUTION: A widening plate 2 having a substantially L-shaped cross section including horizontal portions 2a and rising portions 2b is provided at both ends in the width direction of a synthetic slab deck plate 1 over the entire length (span length) of the synthetic slab deck plate 1, and a concrete 3 is cast on the surfaces of the synthetic slab deck plate 1 and the widening plate 2.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
