PROBLEM TO BE SOLVED: To provide a floor panel capable of reducing the number of joists and fixing a sheet-like holding member for covering a heat insulator.SOLUTION: A floor panel 1 comprises multiple parallel joists 3 and heat insulators 4 and 5 that are disposed on an undersurface of a floor plate 2. The joists 3 are disposed at positions away from ends of the floor plate 2 in a joist arrangement direction. A sheet-like holding material 6, which holds the heat insulators 4 and 5 together with the joists 3 by covering them from underside, is fixed on edge surfaces of the floor plate 2. A fiber insulator is used for the heat insulator 4 located between the joists 3, and a resin foam insulator is used for the heat insulators 5 located at positions on end sides of the floor plate 2 and outer sides of the joists 3.SELECTED DRAWING: Figure 1 |
