PROBLEM TO BE SOLVED: To reduce mandays for the execution of works by installing a panel base body, to which a floor foundation material is annexed, onto the top face of a framework, with which a frame material is joined, and mounting a rail metal fitting, to which a ceiling material is set up, into the panel base body. SOLUTION: The upper floor of a building with a panel base body 4, in which the groove sections of frame materials 7B consisting of U-shaped sectional channel steel are faced oppositely and the frame materials 7B are joined rectangularly to form a framework 2 and a floor foundation material 3 is annexed onto the top face of the framework 2, is formed. A rail metal fitting 5 composed of a U-shaped sectional grooved long-sized body, in which horizontal projecting pieces 30A, 30B are shaped to the upper and lower sections of a vertical long- sized upright piece 29, is fixed into the panel base body 4 through fixtures 9 for cushioning made up of rubber pieces, etc., by screws 26. Accordingly, the damage of the rail metal fitting at the time of transport is prevented while the vibrations of an upper floor section can be damped. |
