Description

Technical Field

[0001] The present invention relates to the structure of an entrance and an ant prevention method for a house.

Background Art

[0002] Generally, in order to ensure the heat insulation performance of a house, a foundation heat insulation material made of foamed foam is arranged along the foundation part arranged along the outer wall (foundation heat insulation structure). However, termites tend to form ant passages in this foundation heat insulation material and progress to the upper part of the foundation heat insulation material, causing damage to wooden materials such as the base and walls arranged on the foundation.

[0003] In order to prevent termite damage as described above, ant prevention maintenance has been proposed in which an ant prevention chemical solution is regularly injected from the underfloor space into the foundation heat insulation material or a sheet or the like arranged between the foundation heat insulation material and the rising part of the foundation (see Patent Document 1 below).

Summary of the Invention

Problems to be Solved by the Invention

[0005] In recent years, many reports have been made of termite invasions from the entrance area. Generally, at the entrance of a house, the surface of the foundation heat insulation material is covered with a cement hardened material such as mortar, and further, tiles or the like are constructed thereon to form an earth floor part. Therefore, when performing the above-described ant prevention maintenance at the entrance, first, a large-scale operation is required in which holes are drilled in the cement hardened material with a drill or the like, an ant prevention chemical solution is injected from there to the foundation heat insulation material side, and then the holes formed in the cement hardened material are repaired.

[0006] This invention was devised in view of the above circumstances, and its main purpose is to provide an entrance structure that allows for easy termite prevention maintenance at the entrance without compromising thermal insulation performance. [Means for solving the problem]

[0007] The present invention relates to a structure for the entrance of a house, comprising: a foundation arranged along the entrance and having a rising portion that extends vertically; a foundation insulation material including foamed foam arranged along the indoor side of the rising portion; a frame arranged above the foundation insulation material; and a floor area arranged on the indoor side of the foundation insulation material, wherein the floor area includes a horizontal portion arranged to cover the ground of the entrance and a vertical portion arranged to cover the foundation insulation material, the upper end of the vertical portion being lower than the upper end of the foundation insulation material, and an exposed portion between the lower surface of the frame and the upper end of the vertical portion in which a part of the foundation insulation material is exposed to the entrance side. [Effects of the Invention]

[0008] By adopting the above configuration, the entrance structure of the present invention allows for easy termite control maintenance at the entrance without compromising thermal insulation performance. [Brief explanation of the drawing]

[Figure 3] This is a partial cross-sectional view of the house corresponding to the position of line III-III in Figure 1. [Figure 4] This is a magnified view of a portion of Figure 3. [Figure 5] This is a magnified view of a section of Figure 3, which explains termite control maintenance. [Figure 6] This is a magnified view of a portion of Figure 3 illustrating other forms of termite control maintenance. [Figure 7] This is a partially enlarged view of Figure 3 of another embodiment. [Figure 8]This is a partial cross-sectional view of a house corresponding to the position of line III-III in Figure 1, which shows a modified example of foundation insulation. [Modes for carrying out the invention]

[0010] One embodiment of the present invention is described below with reference to the drawings. The drawings contain exaggerations and representations that differ from the actual structural dimensional ratios in order to aid in understanding the present invention. Furthermore, the same or common elements are denoted by the same reference numerals throughout multiple embodiments, and redundant explanations are omitted. Moreover, the specific configurations shown in the embodiments and drawings are for the purpose of understanding the content of the present invention, and the present invention is not limited to the specific configurations shown in the illustrations.

[0011] Figure 1 is a partial front view of House 1, Figure 2 is its foundation plan, and Figure 3 is a partial cross-sectional view of House 1 corresponding to the position of line III-III in Figure 2. As shown in Figures 1 to 3, House 1 includes a foundation 2 arranged along the perimeter of the building and an exterior wall 3 fixed to this foundation 2.

[0012] Foundation 2 is, for example, a strip foundation and includes a footing portion 2a embedded in the ground G and a rising portion 2b extending above the ground from the footing portion 2a (in Figure 2, the footing portion 2a is omitted). The rising portion 2b of foundation 2 has an inner surface 2i facing the indoor side and an outer surface 2o facing the outdoor side.

[0013] As shown in Figure 2, the house 1 has an entrance hall 4 inside. The entrance hall 4 is a dirt-floored space that is formed facing the outer perimeter of the house 1 and includes the entrance to the house 1, which is opened and closed by an entrance door 5. As shown in Figures 1 and 2, a part of the foundation 2 is positioned to define a part of the outer edge of the entrance hall 4. In this embodiment, a recess 2c is provided in the rising portion 2b of the foundation 2, with its height partially reduced, and the entrance door 5 is positioned in this recess 2c. However, it goes without saying that the entrance door 5 may be positioned without providing a recess 2c in the rising portion 2b of the foundation 2.

[0014] As shown in FIG. 3, a foundation heat insulating material 7 including a foamed foam is disposed on the inner surface 2i of the rising portion 2b of the foundation 2. The foundation heat insulating material 7 is, for example, a foamed foam formed in a plate shape, and is disposed so as to directly or indirectly contact the inner surface 2i of the rising portion 2b via a sheet material described later. Examples of the foamed foam include polystyrene foam, urethane foam, or phenol foam.

[0015] The upper end 7a of the foundation heat insulating material 7 extends further upward beyond the upper end 2d of the rising portion 2b, for example. Also, the lower end 7b of the foundation heat insulating material 7 is inserted into the ground G. Such a foundation heat insulating material 7 reliably suppresses the heat exchange with the outdoors through the rising portion 2b of the foundation 2 and helps to improve the heat insulating performance of the house 1.

[0016] In the entrance 4, a door frame 8 is disposed above the foundation heat insulating material 7. In the present embodiment, the door frame 8 is disposed along the rising portion 2b, for example, except for the portion of the entrance door 5. In the present embodiment, the door frame 8 includes a frame body 10 made of a wood material that extends horizontally along the upper end 7a of the foundation heat insulating material 7, and a finding cover 11 that extends vertically so as to cover at least the finding surface 10a of the frame body 10. A batten 9 is disposed, for example, at the parting portion between the door frame 8 and the interior material 20.

[0017] In the present embodiment, the frame body 10 is formed by arranging two wood materials side by side in the horizontal direction, but it may be formed of one wood material. The finding cover 11 of the present embodiment is configured in an inverted L-shaped cross section so as to cover the corner portion formed by the finding surface 10a of the frame body 10 and the upper surface of the frame body 10. In other aspects, the door frame 8 may be composed only of the frame body 10 without the finding cover 11. In this specification, when simply expressed as "door frame", the frame body 10 is intended.

[0018] In the entrance 4 of this embodiment, a dirt floor portion 12 is formed on the indoor floor surface of the basic heat insulating material 7. The dirt floor portion 12 is a layer containing a cement hardened material such as mortar and / or concrete, and includes a base layer 13 and a finish layer 14 covering the base layer 13. These layers are formed, for example, at different construction stages. In other embodiments, the base layer 13 may be omitted.

[0019] The base layer 13 is, for example, a concrete layer, and extends horizontally from the inner surface 7c facing the indoor side of the basic heat insulating material 7 so as to cover the ground of the entrance 4. The base layer 13 can prevent moisture from the ground. A moisture-proof sheet (not shown) may be arranged on the lower surface of the base layer 13.

[0020] The finish layer 14 is, for example, a mortar layer, and is formed after the base layer 13 is constructed. The finish layer 14 of this embodiment includes a horizontal portion 14a and a vertical portion 14b, and decorative tiles 15 are appropriately arranged on their surfaces. Note that the horizontal portion 14a may be a concrete layer.

[0021] The horizontal portion 14a of the finish layer 14 is arranged so as to cover the ground of the entrance 4. In this embodiment, the horizontal portion 14a is arranged so as to cover the ground through the base layer 13.

[0022] The vertical portion 14b is arranged so as to cover the basic heat insulating material 7. More specifically, the vertical portion 14b extends vertically so as to cover the inner surface 7c of the basic heat insulating material 7.

[0023] [[ID=第十九]] FIG. 4 is a partially enlarged view of the vicinity of the vertical portion 14b of the finish layer 14 in FIG. 3. As shown in FIGS. 3 and 4, in this embodiment, the upper end 14c of the vertical portion 14b is located lower than the upper end 7a of the basic heat insulating material 7. Thereby, in the entrance 4 of this embodiment, an exposed portion 16 where a part of the inner surface 2i of the basic heat insulating material 7 is exposed to the entrance 4 side is provided between the lower surface 8a of the frame 8 and the upper end 14c of the vertical portion 14b. The exposed portion 16 may be continuously formed along the foundation 2 arranged along the outer periphery of the entrance 4, or may be partially formed.

[0024] [Effect] In the structure of the entrance 4 of this embodiment, configured as described above, the foundation insulation material 7 has an exposed portion 16 that is exposed to the entrance 4 side. Therefore, termite prevention maintenance of the entrance 4 can be performed by using a syringe 30 filled with termite-repellent liquid 31 and injecting the termite-repellent liquid 31 between the foundation insulation material 7 and the rising portion 2b of the foundation 2 through the exposed portion 16, as shown in Figure 5. Furthermore, since the foundation insulation material 7 is made of foamed foam, the process of inserting the needle 32 of the syringe 30 into it does not require the great effort of drilling a hole in the floor portion 12. Thus, with the structure of the entrance 4 of this embodiment, termite prevention maintenance of the entrance 4 can be easily performed.

[0025] In a more specific example of termite prevention maintenance, a worker located at the entrance 4 first inserts the needle 32 of a syringe 30 into the exposed portion 16 of the foundation insulation 7. This can be done with minimal force, as described above.

[0026] The position and direction in which the needle 32 is inserted vary depending on the positional relationship between the exposed portion 16 and the rising portion 2b. In the example shown in Figure 5, the tip of the needle 32 reaches the space between the foundation insulation material 7 and the rising portion 2b of the foundation 2. In this state, the piston 33 of the syringe 30 is pushed in, allowing the termite-repellent liquid 31 to be injected between the foundation insulation material 7 and the rising portion 2b of the foundation 2. The injected termite-repellent liquid 31 spreads along the rising portion 2b, providing a termite-repellent effect for a certain period of time.

[0027] The termite control solution 31 can be any type as long as it has termite control properties, but examples include pyrethroid-like insecticides (silafluofen, etofenprox, etc.), pyrethroid-based insecticides (bifenthrin, cypermestone, deltamethrin, permethrin, permethrin, allethrin, tralomethrin, etc.), carbament-based insecticides (provoxur, fenobucarb, sevin, etc.), and chlornicotil-based insecticides (imidacloprid, acetapride). The following can be used as the above-mentioned pesticides: clothianisin, nitroganillin-based pesticides (dinotefuran, etc.), organophosphate insecticides (foxim, tetraclocupinphos, fenitrothion, propetanphos, etc.), pyrazole-based pesticides (fibronil, etc.), chlorphenol-based pesticides (4-bromo-2,5-dichlorophenol (BDCP), etc.), phenylpyrrole-based pesticides (chlorfenavir, etc.), cypress oil, turmeric, capric acid, coconut oil, palm oil, etc.

[0028] Further preferred embodiments of the present invention are described below. [Sheet material] As shown in Figures 3 to 5, it is preferable to pre-place a sheet material 40 that has been impregnated with an anti-termite solution 31 and / or that can be impregnated with the anti-termite solution 31 between the rising portion 2b and the foundation insulation material 7. In this configuration, the injected anti-termite solution 31 is absorbed by the sheet material 40 and can remain between the foundation insulation material 7 and the rising portion 2b of the foundation 2 for a long period of time. This provides an anti-termite effect over a long period of time.

[0029] Preferably, the sheet material 40 includes a first portion 41 that contacts the outer surface 7d of the foundation insulation material 7 facing the outside, and a second portion 42 that contacts the lower end 7b of the foundation insulation material 7, as shown in Figure 3. Such a sheet material 40 can distribute the injected termite-resistant liquid 31 over a wider area of ​​the surface of the foundation insulation material 7.

[0030] In a preferred embodiment, the foundation insulation material 7 and the sheet material 40 each extend further upward beyond the upper end 2d of the rising portion 2b of the foundation 2. As a result, in this embodiment, the sheet material 40 is located in the area where the exposed portion 16 is projected horizontally outward. In this embodiment, as shown in Figure 6, if the needle 32 of the syringe 30 can impregnate the sheet material 40 with the termite repellent liquid 31, the termite repellent liquid 31 can be delivered to a wide area of ​​the outer surface 7d of the foundation insulation material 7 via the sheet material 40. This embodiment is desirable because it widens the range of insertion positions for the needle 32 and improves the degree of freedom in the process.

[0031] Various materials can be used for the sheet material 40, such as nonwoven fabric, porous sheet, or paper material. Alternatively, board paper that has been previously fixed to the outer surface 7d of the foundation insulation material 7 may be used as the sheet material 40.

[0032] As shown in Figure 6, in addition to or in conjunction with the above configuration, the foundation insulation material 7 may have guide holes 45 formed therein for guiding the termite-repellent liquid 31 between the sheet material 40 and / or between the foundation insulation material 7 and the rising portion 2b of the foundation 2. The guide holes 45 are micro-holes that open at one end in the exposed portion 16 and at the other end in the outer surface 7d of the foundation insulation material 7. The termite-repellent liquid 31 may be supplied to the sheet material 40, etc., from these guide holes 45, for example.

[0033] [Barrier layer] As shown in Figure 6, it is desirable that the entrance 4 be provided with a barrier material 50 for supplying the termite-repellent liquid 31 to the appropriate location.

[0034] The barrier material 50 may include, for example, a first barrier material 51 placed between the upper end 7a of the foundation insulation material 7 and the frame 8. The first barrier material 51 is made of a material that is not impregnated with the termite-resistant liquid 31 impregnated into the sheet material 40. Such a first barrier material 51 can prevent the termite-resistant liquid 31 impregnated into the sheet material 40 from being absorbed by the frame 8 or nearby materials, thereby suppressing a decrease in the termite-resistant effect on the foundation insulation material 7.

[0035] Furthermore, the barrier material 50 may include a second barrier material 52. The second barrier material 52 is positioned above the rising portion 2b and in contact with the outdoor surface of the sheet material 40. Therefore, the second barrier material 52 is not located between the rising portion 2b of the foundation 2 and the sheet material 40. The second barrier material 52 prevents the termite-resistant liquid 31 impregnated in the sheet material 40 from being absorbed by the sill or wall material made of wood placed on the rising portion 2b, thereby suppressing a decrease in the termite-resistant effect on the foundation insulation material 7.

[0036] The barrier material 50 described above can be any material without particular limitations, as long as it is not impregnated with the termite-repellent liquid 31. For example, resin sheets, resin plates, metal plates, etc., are preferred.

[0037] [Face cover] Figure 7 shows a partially enlarged view of Figure 3 as another embodiment. As shown in Figure 7, in this embodiment, the visible cover 11 extends below the lower surface 8a of the frame 8 so that at least a portion of it overlaps vertically with the exposed portion 16 of the foundation insulation material 7. In this embodiment, at least a portion of the exposed portion 16 is concealed by the visible cover 11 and is difficult to see from the outside. Therefore, in this embodiment, deterioration of the appearance of the entrance 4 can be prevented.

[0038] In this embodiment, the vertical portion 14b of the floor area 12 includes an inclined upper end surface 14e. More specifically, the upper end surface 14e of the vertical portion 14b is inclined such that its height gradually decreases from the foundation insulation material 7 towards the interior side. Furthermore, the highest point 14c of the inclination of the upper end surface 14e is located above the lower end 11a of the visible cover 11, and the lowest point 14d of the inclination of the upper end surface 14e is located below the lower end 11a of the visible cover 11. With this configuration, the exposed portion 16 becomes even less visible from the entrance 4, further improving the appearance of the entrance 4. Also, as shown by the thick dashed line, the needle 32 of the syringe 30 during termite prevention maintenance can be inserted into the exposed portion 16 at an inclination along the upper end surface 14e of the vertical portion 14b, without worsening the workability of the termite prevention maintenance process.

[0039] Figure 8 is a modified example of the foundation insulation material 7, a partial cross-sectional view of a house corresponding to the position of line III-III in Figure 2. As shown in Figure 8, the foundation insulation material 7 may also consist of a vertical portion 71 extending vertically along the rising portion 2b of the foundation 2, and a horizontal portion 72 extending horizontally along the underside of the floor slab 12 (in this example, the subfloor 13). The vertical portion 71 and the horizontal portion 72 are connected so as to be in contact with each other, and the foundation insulation material 7 has an L-shaped cross-section. Such a foundation insulation material 7 can further improve the insulation performance near the entrance of the house 1.

[0040] Furthermore, because the foundation insulation material 7 is formed in an L-shape in cross-section, the thickness of the vertical portion 71 and the horizontal portion 72 can be made thinner, for example. This helps to reduce insulation costs and also expand the entrance space.

[0041] Furthermore, generally, the floor slab 12 receives heat from the ground G, which experiences little temperature fluctuation throughout the year. Therefore, the floor slab 12 is less affected by heat from the outside compared to the rising portion 6 of the foundation 2. From this perspective, the thickness t2 of the horizontal portion 72 of the foundation insulation material 7 may be set to be smaller than the thickness t1 of the vertical portion 71. This reduces the amount of insulation material used in the horizontal portion 72, further lowering insulation costs.

[0042] Although embodiments of the present invention have been described in detail above, the present invention is not limited to the specific disclosures described above, and can be implemented with various modifications within the scope of the technical idea described in the claims. Furthermore, the present invention is naturally intended not only to be implemented in isolation, but also to be implemented in combination with the features of one or more other embodiments.
