Description of the Related Art A floor structure in which a plurality of floor joists are provided substantially orthogonally on a beam and a floor board is stretched over the floor joists is known.

In such a floor structure, in order to impart thermal insulation performance, as described in the above-mentioned Japanese Patent Application Laid-Open No. 8-144474, a floor base sheet is provided over the lower surfaces of a plurality of floor joists. A heat insulating material is filled in a space defined by the floor panel lower surface, the floor joist side surface, and the floor base sheet upper surface.

In the floor structure where the insulation is filled in the part,
When the thickness of the heat insulating material is almost the same as the height of the floor joist, the heat insulating material is stored in the space between the bottom surface of the floor plate, the side surface of the floor joist and the upper surface of the floor base sheet, but the thickness of the heat insulating material is floor. When the thickness is larger than the height of the joist, there is a disadvantage that the thick heat insulating material cannot be stored in the space between the lower surface of the floor board, the side surface of the floor joist and the upper surface of the floor base sheet. As described above, a heat insulating material whose thickness is larger than the height of the floor joist is necessary especially in a cold region. Also, in order to satisfy the recent trend toward higher insulation of houses, it is necessary to use thicker insulation.
