PROBLEM TO BE SOLVED: To provide a fire resistant structure of a composite floor slab for delaying or restraining reduction in yield strength by a temperature rise, by restraining the temperature rise in a deck plate and concrete for a composite slab in a fire, by utilizing the thermally insulating action or the effect, by forming a simple thermally insulating space, by using a shape and a structure of the deck plate for the composite slab. SOLUTION: This composite floor slab structure is formed by placing the concrete 5 on it by installing the deck plate 1 for the composite slab on a beam. The thermally insulating space 11 for wholly closing a lower part of a projecting part 1A, is formed by sticking a flat steel cover plate 10 to an under surface of the deck plate for the composite slab.
