2. Description of the Related Art Generally, temperature changes are smaller in the ground than in the outside air, and relatively warm in winter and cool in summer. Various houses called passive solar systems using such underground temperature changes have been proposed. All of these methods circulate air that touches the ground to regulate the temperature of the living space. In this case, the underground heat storage is once exchanged with air to circulate the air, and thermal efficiency is poor.

[0003] On the other hand, the direct use of underground heat storage,
It has also been proposed to transfer underground heat storage directly to flooring. However, for that purpose, it is necessary to make the underground and the flooring thermally continuous, and if a hollow portion that circulates with the outside air is provided on the way such as a raised floor, no effect can be obtained. Therefore, an attempt has been made to put concrete as a floor foundation on a gravel floor and directly attach a floor plate to the upper surface of the foundation concrete. For example, architect

In the prior art, when the floorboard is directly adhered to the upper surface of the foundation concrete, it is necessary to minimize the allowable error of the upper surface of the foundation concrete. When a long bar or plate is used, an error of about 1 to 10 mm occurs, and the work becomes complicated to finish the concrete horizontally and uniformly over a wide area, resulting in a problem of poor construction efficiency.
This was particularly noticeable in the recent shortage of engineers. Further, even after the concrete is solidified, mortar is applied to the upper surface of the concrete, and the mortar is adjusted to finish the surface horizontally and uniformly.

[0005] It is considered that this underground heat storage heats the surrounding ground by sunlight or the like, stores heat also in the ground below the floor, and stores heat in the gravel floor by the heat stored in the ground. According to the experiments and considerations of the inventor, it is considered that the heat storage of the gravel floor is not the heat storage of the gravel itself, but the total heat storage of the fine air layer existing between the adjacent gravel and the gravel. In the gravel layer in the enclosed space, the lower gravel near the ground has some moisture remaining, but the upper gravel far from the ground is dry.
