PROBLEM TO BE SOLVED: To provide good filling property of concrete for strengthening integration of a floor steel plate and concrete, and also to reduce cost by reducing material cost and the number of work man-hour. SOLUTION: A composite floor slab 100 is composed of the floor steel plate 10, an adhesion material 20 and the concrete 30. Also, the composite floor slab 100 includes an upper distribution reinforcement 31 and an upper main reinforcement 32 in the upper part of the concrete 30. On an upper surface of the floor steel plate 10 having a plurality of ribs 11, the adhesion material 20 is applied and the concrete 30 is filled. Hereby, an existing stud dowel or the like is not required, and thus, the material cost and the number of working man-hour can be reduced. COPYRIGHT: (C)2010,JPO&INPIT
