きが生じてしまう恐れがあった。By the way, in the above-mentioned conventional configuration. Due to variations in the height dimension A of the joist 2 and variations in the thickness of the heat storage board 1 and warpage, it is very difficult to maintain the dimension B of the space 6 at a predetermined dimension, and it is difficult to obtain a stable floor temperature. was there. That is, if the B dimension of the space 6 changes and the distance between the heat storage board 1 and the floor plate 3 becomes smaller than a predetermined distance, the heat radiation from the heat storage board 1 improves and the floor temperature rises. Becomes larger than a predetermined dimension, and the distance between the heat storage board 1 and the floor plate 3 becomes larger than a predetermined distance, heat radiation from the heat storage board 1 deteriorates and the floor temperature becomes low, resulting in variations in floor temperature. There was a risk that this would occur.

When the temperature T1 of the upper part is low and the surface of the floorboard 3 is touched by hand,
There was a risk that temperature variations would be noticeable. In order to solve the problem of keeping the B dimension of the space 6 at a predetermined dimension, an elastic heat insulating material is installed in the lower part, and a spacer is provided between the upper surface of the heat storage board 1 and the lower surface of the floor board 3 so that the B of the space 6 A method of keeping the dimensions at a predetermined size has been proposed, but this method improves the temperature difference between the surface temperature of the floorboard 3 between the joists 2 and 2 and the surface temperature of the floorboard 3 above the joists 2. Since the effect is small and a spacer as a separate component is required, there remains a problem that the cost is increased including the construction.

題もある。Further, in this type of heat storage type floor heating apparatus, members such as the heat insulating material 4, the heat storage board 1, and the heating element 5 are arranged between the joists 2 to form the floor. The floor height is higher than that of a floor with a floor finish without floor heating. Therefore, the floor height can be reduced by improving the heat storage efficiency of the heat storage board 1 to reduce the thickness of the heat storage board 1, or by using a heat insulating material having high heat insulation efficiency to reduce the thickness of the heat insulating material 4. Although a means for doing so is conceivable, in this type of heat storage type floor heating system,
There is also a problem that it is desirable to have a structure in which the floor height can be made as low as possible.

きが生じてしまう恐れがあった。By the way, in the above-mentioned conventional configuration, the B dimension of the space 6 is set to a predetermined dimension due to variations in the height dimension A of the joist 2 and variations in the thickness of the heat storage board 1, warpage and the like. It was very difficult to maintain, and there was a problem that it was difficult to obtain a stable bed temperature. That is, if the B dimension of the space 6 changes and the distance between the heat storage board 1 and the floor board 3 becomes smaller than a predetermined distance, the heat radiation from the heat storage board 1 improves and the floor temperature rises. Becomes larger than a predetermined dimension, and the distance between the heat storage board 1 and the floor plate 3 becomes larger than a predetermined distance, heat radiation from the heat storage board 1 deteriorates and the floor temperature becomes low, resulting in variations in floor temperature. There was a risk that this would occur.
