PROBLEM TO BE SOLVED: To provide a steel deck plate for a floor form capable of securing the maximum strength and the maximum space cover area, maximizing work efficiency and reducing costs by using a steel material with the largest versatility.SOLUTION: In a steel deck plate 1 for a floor form, three leg parts 3 arranged in parallel in a span direction S are suspended downward from the rear surface of a plane plate part 2, are arranged so that all intervals between the respective adjacent leg parts equal to each other, moreover, each of the respective leg parts is formed of: a wood siding wall-like part 10 which falls from the rear surface of the plane plate part 2 by predetermined distance; and a swollen part 4 which is integrally formed and has a triangular space part whose height is larger than length of a bottom side at a lower end part of the wood siding wall-like part 10, the intervals between the respective legs are 175 mm, suspended length of the respective leg parts is 100 mm, and a ratio of height H to length W of a bottom side of a triangular part 4 is 1.5 to 2.8. |
