BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described based on the drawings. The drawings may include exaggerated representations and representations that differ from the dimensional ratios of the actual structures in order to facilitate understanding of the content of the invention. In addition, throughout each embodiment, the same or common elements are denoted by the same reference numerals, and overlapping descriptions are omitted. Furthermore, the specific configurations shown in the embodiments and drawings are for understanding the content of the present invention, and the present invention is not limited to the illustrated specific configurations.

FIG. 1 shows a partial cross-sectional view of a foundation 2 of a house 1 of this embodiment. As shown in FIG. 1, a house 1 of this embodiment has a foundation 2 and an outer wall 3 disposed thereon. Regarding the foundation 2 and the outer wall 3, conventional configurations are applied to items not specifically described.

The foundation 2 of this embodiment is arranged along the outer circumference of the house 1 and is made of, for example, reinforced concrete. Foundation 2 includes a base portion 4 and an upright portion 5 . The base portion 4 extends horizontally in the ground of the house 1 .

The rising portion 5 extends upward from the widthwise center of the base portion 4 and protrudes from the ground G. As shown in FIG. Moreover, the rising part 5 is arranged so as to surround the underfloor space 6 of the house 1 . An air supply hole 7 for introducing outside air into the underfloor space 6 is formed in the rising portion 5 of the present embodiment. The air introduced into the underfloor space 6 is heat-exchanged via the ground with underground heat whose temperature changes little throughout the year. As a result, the underfloor space 6 can store air that is relatively cool in summer and relatively warm in winter compared to the outside air. The air in the underfloor space 6 is cleaned by, for example, a filter or the like and introduced into the living space 8 above the floor. As a more desirable aspect, the house 1 of this embodiment is provided with a ventilation system capable of blowing the air in the underfloor space 6 to the living space 8 with a blower or the like. From the viewpoint of energy saving, it is desirable that the living space 8 is supplied with air having a temperature as close as possible to the temperature at which the occupants feel comfortable (for example, the heat-exchanged air of the underfloor space 6). Therefore, in order to maintain the temperature of the heat-exchanged air in the underfloor space 6, further improvement in the heat insulating properties of the rising portion 5 is required.

A basic decorative panel 10 is arranged on the outer surface 5o of the rising portion 5 facing the outside of the building. FIG. 2 shows an enlarged sectional view of the rising portion 5 and the basic decorative panel 10. As shown in FIG. As shown in FIG. 2, between the outer surface of the rising portion 5 and the basic decorative panel 10, a ventilation layer 12 is formed as a gap through which air can pass. Further, the base decorative panel 10 is separated from the ground G and the outer wall 3 so that the upper portion 12a and the lower portion 12b of the ventilation layer 12 can communicate with the outside air.

In the present invention, since the ventilation layer 12 is formed between the outer surface 5o of the rising portion 5 and the basic decorative panel 10, the ventilation layer 12 plays the role of a heat insulating material and is designed to avoid interference with the bundle. The heat insulating property can be improved at the rising portion 5 of the foundation 2 without requiring any ingenuity.

In addition, in the present invention, the upper and lower parts 12a and 12b of the ventilation layer 12 of the basic decorative panel 10 are separated from the ground G and the outer wall 3 so as to be able to communicate with the outside air. The introduction of air to 6 is unhindered. Therefore, it is possible to prevent the basic decorative panel 10 from impairing the ventilation of the underfloor space 6. - 特許庁According to the present invention, such a mechanism can improve the thermal insulation of the rising portion 5 of the foundation while maintaining the ventilation of the underfloor space 6 without requiring design measures to avoid interference with the bundles. . Further, in the present invention, since the ventilation layer 12 enhances the heat insulation, there is no need to use a conventional heat insulating material outside the rising portion 5 . As a result, it is possible to prevent termite roads that tend to be formed in the heat insulating material, and to suppress termite damage.

A more detailed configuration of the present embodiment will be described below. Each configuration described below represents a specific aspect of the present embodiment. Therefore, the present invention can exhibit the above effects even if it does not have the configuration described below. Further, even if any one of the configurations described below is applied singly to the house of the present invention having the features described above, it is possible to expect an improvement in performance according to each configuration. Furthermore, when some of the respective configurations described below are applied in combination, it is possible to expect a combined improvement in performance according to each configuration.

If the basic decorative panel 10 covers at least a part of the outer surface 5o, an improvement in heat insulation can be expected. From the viewpoint of enhancing heat insulation, the basic decorative panel 10 desirably covers at least 50% or more, more desirably 80% or more of the height of the raised portion 5 . As a further desirable aspect, the basic decorative panel 10 of this embodiment is arranged substantially continuously along the outer wall 3 so as to surround the underfloor space 6 . As a result, further improvement in heat insulation can be expected.

From the same point of view, the basic decorative panel 10 preferably covers 50% or more of the total area of the raised portion 5 of the house 1, more preferably 80% or more of the total area. As a more desirable aspect, the basic decorative panel 10 of this embodiment substantially covers the entire rising portion 5 except for the entrance, etc., where it cannot be arranged.

It is desirable that the outer surface 5o of the rising portion 5 and the basic decorative panel 10 are arranged parallel to each other so that a constant gap t1 is formed. Moreover, the gap t1 of the ventilation layer 12 can be set as appropriate. The gap t1 in this embodiment is set to 5 to 50 mm. By setting the gap t1 to 5 mm or more, outside air can be efficiently supplied to the underfloor space 6 through the ventilation layer 12, and ventilation is maintained. On the other hand, by setting the gap t1 to 50 mm or less, it is possible to prevent outside air from being introduced into the air-permeable layer 12 more than necessary, thereby maintaining heat insulation. From this point of view, the gap t1 is desirably 5-30 mm, more desirably 9-18 mm.

The basic decorative panel 10 has an upper end 10a and a lower end 10b in the height direction. A distance L1 between the upper end 10a of the basic decorative panel 10 and the outer wall 3 can be set appropriately, and is, for example, 30 mm or less, preferably 5 to 10 mm. Similarly, the distance L2 between the lower end 10b of the basic decorative panel 10 and the ground G can be set as appropriate, and is, for example, 30 mm or less, preferably 5 to 10 mm. As a result, the ventilation and heat insulation properties of the underfloor space 6 are improved in a well-balanced manner.

FIG. 3 shows a partial perspective view of the basic decorative panel 10 and the rising portion 5. As shown in FIG. In addition, in FIG. 3, a part of the basic decorative panel 10 is cut so that the configuration can be easily understood. As shown in FIG. 3, the basic decorative panel 10 is supported on the rising portion 5 by crosspieces 15 extending in the vertical direction. Although omitted in FIG. 3, a plurality of crosspieces 15 are spaced apart in the horizontal direction. As a result, the movement of air in the vertical direction in the ventilation layer 12 is not hindered by the crosspieces 15, and the ventilation of the underfloor space 6 is maintained. In a more desirable mode, it is desirable that the basic decorative panel 10 is detachably supported on the crosspiece 15 by means of screws or the like. Thereby, the maintainability of the basic decorative panel 10 and the rising portion 5 can be improved.

FIG. 4 shows a front view of the outer wall 3 and the basic decorative panel 10 viewed from the outside of the building. In addition, in FIG. 4, the air supply hole 7 and the crosspiece 15 are indicated by broken lines. As shown in FIG. 4, the basic decorative panel 10 preferably covers the air supply holes 7 formed in the rising portion 5. As shown in FIG. In a more desirable mode, a plurality of air supply holes 7 are formed at different positions, and each air supply hole 7 is covered with a basic decorative panel 10 . As a result, the ventilation volume of the air supply hole 7 is less likely to be affected by the wind pressure, and a stable ventilation volume can be ensured. Further, in such a mode, even when snow is accumulated, if the snow is accumulated up to the height of the basic decorative panel 10, the space between the lower end 10b of the basic decorative panel 10 and the ground G is merely blocked by the snow. Therefore, even when there is the above-described snow cover, the air supply hole 7 can take in the air supplied from between the outer wall 3 and the upper end 10a of the basic decorative panel 10 into the underfloor space 6, thereby maintaining ventilation. can be done.

The base decorative panel 10 is preferably perforated with a plurality of air holes 18 for the passage of air. The opening area of the air hole 18 is smaller than the opening area of the air supply hole 7 provided in the rising portion 5 . Such air holes 18 can maintain the heat insulation of the ventilation layer 12, and ensure the ventilation of the underfloor space 6 even when the lower part 12b of the ventilation layer 12 is blocked by accumulated snow or the like. can be done.

The air hole 18 is provided at a different position from the air supply hole 7 provided in the rising portion 5, for example. Thereby, the heat insulating property of the ventilation layer 12 is improved. Moreover, it is desirable that the air hole 18 is provided above the air supply hole 7 . As a result, the air holes 18 are less likely to be blocked even when snow piles up, ensuring ventilation. Further, in this embodiment, for example, a plurality of air holes 18 are provided at a pitch of 500 to 1500 mm in the horizontal direction. Such air holes 18 can enhance heat insulation and ventilation in a well-balanced manner.

Various materials such as ceramic siding, slate siding, and steel plate can be applied to the base decorative panel 10 . Desirably, in this embodiment, the base decorative panel 10 and the outer wall 3 have a common decorative finish. As a result, the design of the house 1 can be improved, and the piping holes and the like can be easily hidden.

As shown in FIG. 1, a heat insulating material 20 is provided on the inner surface 5i of the rising portion 5 opposite to the outer surface 5o. The heat insulating material 20 is made of, for example, foamed urethane foam or the like, and is attached so as to cover the inner surface 6i of the rising portion 5. As shown in FIG. Thereby, the heat insulating property of the rising portion 5 is further improved. Further, since the heat insulating material 20 of the present embodiment is provided with holes communicating with the air supply holes 7 , the introduction of air from the air supply holes 7 into the underfloor space 6 is not hindered.

The configuration of the heat insulating material 20 is not limited to the above aspect. FIG. 5 shows a cross-sectional view showing another aspect of the heat insulating material 20. As shown in FIG. As shown in FIG. 5, the heat insulating material 20 may have an L-shaped cross section that covers the inner surface 5i of the rising portion 5 and the outer surface 21o of the dirt floor portion 21 that continues to the rising portion 5 and extends horizontally on the ground G. Such a heat insulating material 20 can exhibit even better heat insulating properties.

Although the particularly preferred embodiments of the present invention have been described in detail above, the present invention is not limited to the illustrated embodiments and can be modified in various ways.

The following examples and comparative examples were prepared, and the thermal insulating properties of the rising portion of the foundation were calculated.
Example: A house including the foundation, foundation facing panels and insulation shown in FIG.
Comparative example: This is a house from which the basic decorative panel was removed from the example.

The examples and comparative examples have substantially the same configuration except for the presence or absence of the basic decorative panel.

The linear heat transmission coefficient (W/mK) was calculated as an index of the thermal insulation of the rising part of the foundation. The smaller the linear heat transmission coefficient, the better the thermal insulation. The amount of air passing through the air supply hole and the linear heat transmission coefficient are calculated based on, for example, JIS regulations.
The results of the tests are shown in Table 1.

As shown in Table 1, it can be understood that the linear heat transmission coefficient of the example is about 4.2% lower than that of the comparative example. That is, it was confirmed that the configuration of the present invention significantly improved the heat insulating properties.
