Claims

[Scope of utility model registration request]

This is a floor heat insulating board that is fitted between adjacent joists 2, 2, and has a rectangular plate shape that allows the upper surface 3 to be in substantially close contact with the lower surface 6 of the floorboard 5 when it is fitted between the joists 2, 2, Each of the side edge portions 10, 10 on the joist side is formed such that an inner edge 11 thereof is continuous with the upper surface 3 of the central portion 7 via the water receptacle stepped portion 12, and the upper surface of the central portion 7. 3 are sloped surfaces 13, 13 for both flows that slope downward toward the water receiving step portions 12, 12 with the longitudinal center line l extending in the joist direction as the boundary, and on both sides of the central portion 7, A heat insulating board for a floor, characterized in that an appropriate number of drain holes 15 are provided vertically through the drain holes 15 for draining rainwater that flows down an inclined surface 13 and is received by a water receiving stepped portion 12.
