Description

Technical Field

[0007]

[0001] The present invention relates to a building.

Background Art

[0002] In a building such as a house, an outer wall portion that partitions the inside and the outside is provided over the entire circumference of the outer periphery thereof. The outer wall portion has a heat insulation layer made of a heat insulating material such as glass wool inside (see, for example, Patent Document 1). Thereby, the heat insulation performance of the outer wall portion is ensured.

[0003] In recent years, in order to improve the heat insulation performance of the outer wall portion, the outer wall portion is recessed inward to increase the thickness of the outer wall portion, and the thickness of the heat insulation layer is also increased. In this case, for example, it is conceivable to increase the thickness over the entire circumference of the outer wall portion.

Summary of the Invention

Problems to be Solved by the Invention

[0005] In a building, a bathroom may be provided adjacent to the outer wall portion. The bathroom is generally formed by a box-shaped bath unit. Here, when the above-described configuration in which the entire circumference of the outer wall portion is recessed inward to increase the thickness is applied to a building provided with such a bathroom, it is necessary to shift the bath unit inward by the amount by which the outer wall portion is recessed. Therefore, there is a risk of affecting the room planning, such as the room adjacent to the bath unit (bathroom) becoming narrow.

[0006] Further, when the thickness of the heat insulation layer is increased over the entire circumference of the outer wall portion, there is also a problem that excessive heat insulation occurs and the cost is increased unnecessarily.

[0007] This invention has been made in view of the above circumstances, and its main objective is to provide a building that can appropriately improve thermal insulation performance while minimizing the impact on room planning. [Means for solving the problem]

[0008] To solve the above problems, the building of the first invention is provided with an exterior wall that is installed around the entire perimeter of the building and separates the interior from the exterior, the exterior wall having an insulating layer inside the wall, and a unit room formed inside a box-shaped equipment unit is provided as a room adjacent to the exterior wall, the portion of the exterior wall adjacent to the unit room is the first wall, the portion not adjacent to the unit room is the second wall, the second wall is formed with a greater thickness than the first wall by extending it further inward, and the thickness of the insulating layer is greater than that of the first wall.

[0009] According to the first invention, the exterior wall portion, which extends around the entire perimeter of the building, is divided into a first wall portion, where it is adjacent to a unit room, and a second wall portion, where it is not adjacent to a unit room. The second wall portion is formed further inward than the first wall portion, resulting in a greater thickness than the first wall portion, and also a greater thickness of the insulation layer in the second wall portion. This improves the thermal insulation performance of the exterior wall portion. Furthermore, in this configuration, since the thermal insulation performance is not enhanced in a portion of the exterior wall portion (the first wall portion), excessive insulation can be prevented. Therefore, the thermal insulation performance can be appropriately improved.

[0010] Furthermore, since the first wall adjacent to the unit room (in other words, the equipment unit) is not extended inward, there is no need to shift the equipment unit inward by the amount that would have been required for extension. Therefore, the impact on room planning, such as the narrowing of the room adjacent to the unit room due to shifting the equipment unit, can be minimized. Thus, it is possible to appropriately improve insulation performance while minimizing the impact on room planning.

[0011] The building of the second invention is, in the first invention, wherein the exterior wall portion has a pair of wall portions that are perpendicular to each other in a plan view, the unit room is a corner room adjacent to the pair of wall portions, and each portion of the pair of wall portions adjacent to the unit room is the first wall portion which is thinner than the second wall portion.

[0012] According to the second invention, the exterior wall has a pair of wall sections that are perpendicular to each other in a plan view. The unit rooms are corner rooms adjacent to each of the pair of wall sections. In this configuration, if the entire perimeter of the exterior wall is extended inward to increase its thickness, each of the pair of wall sections will be extended inward, which may necessitate shifting the equipment units in two directions. Therefore, it is thought that this will have a significant impact on the room planning.

[0013] In this respect, the second invention is characterized in that each portion of a pair of wall sections adjacent to the unit room is a first wall section with a smaller thickness, that is, a first wall section that does not extend inward towards the interior. This makes it possible to appropriately improve thermal insulation performance while minimizing the impact on room planning in configurations where the unit room is a corner room.

[0014] The building of the third invention is, in the first or second invention, a bathroom formed inside the bathroom unit as the equipment unit, where the unit room is a bathroom formed inside the bathroom unit as the equipment unit.

[0015] According to the third invention, the effects of the first or second invention can be obtained in a configuration in which the bathroom formed by the bath unit is provided adjacent to the exterior wall.

[0016] The building of the fourth invention is, in the third invention, wherein the exterior wall portion has a pair of wall portions that are perpendicular to each other in a plan view, the bathroom is a corner room adjacent to each of the pair of wall portions, a washroom and a toilet are provided as rooms adjacent to the bathroom, the washroom is adjacent to the bathroom in the thickness direction of one of the pair of wall portions, the toilet is adjacent to the bathroom in the thickness direction of the other of the pair of wall portions, and each portion of the pair of wall portions adjacent to the bathroom is the first wall portion which is thinner than the second wall portion.

[0017] According to the fourth invention, the bathroom is a corner room, and a washroom and toilet are provided adjacent to the bathroom. The washroom is adjacent to the bathroom in the thickness direction of one of the pair of walls (hereinafter referred to as the first thickness direction). The toilet is adjacent to the bathroom in the thickness direction of the other wall (hereinafter referred to as the second thickness direction).

[0018] In this configuration, if the entire perimeter of the exterior wall is extended inward to increase its thickness, one wall section will be extended inward in the first thickness direction, and the other wall section will be extended inward in the second thickness direction. In this case, it becomes necessary to shift the bathroom unit in both the first and second thickness directions, resulting in the washroom adjacent to the bathroom in the first thickness direction and the toilet adjacent to the bathroom in the second thickness direction becoming smaller. Since the washroom and toilet are already small spaces, further reduction in size is likely to cause inconveniences such as reduced usability. Alternatively, it may be possible to shift the washroom and toilet by the amount extended inward to secure space for them, but this would likely have a significant impact on the planning of other rooms.

[0019] In this regard, in the fourth invention, in a pair of wall portions, each part adjacent to the bathroom in the adjacent room has a first wall portion with a small thickness, that is, a first wall portion that does not bulge inward toward the indoor side. Thereby, in a configuration where a washroom and a toilet are adjacent to a bathroom in a corner room, it is possible to appropriately improve the heat insulation performance while reducing the influence on the room planning.

Embodiments for Carrying Out the Invention

[0021] Hereinafter, an embodiment embodying the present invention will be described with reference to the drawings. Note that FIG. 1 is a plan view showing the floor plan of the building interior.

[0022] As shown in FIG. 1, the building 10 is a detached unit-type house. The building 10 has a rectangular parallelepiped building unit 20, and is configured by arranging a plurality of such building units 20 side by side. The building unit 20 includes columns 20a erected at its four corners, and upper and lower beams spanned between the upper and lower ends of adjacent columns 20a. In FIG. 1, for convenience of explanation, only the columns 20a of each building unit 20 are shown.

[0023] The building 10 has a substantially rectangular shape in plan view. A plurality of rooms 11 to 16 are provided inside the building 10. The plurality of rooms 11 to 16 include an entrance 11, a living-dining-kitchen 12, a Japanese-style room 13, a washroom 14, a bathroom 15, and a toilet 16.

[0024] On the outer periphery of the building 10, an outer wall portion 21 that partitions the inside and the outside over the entire circumference is provided. Although illustration is omitted, the outer wall portion 21 includes an outer wall facing the outside, an inner wall facing the inside, a frame for supporting these wall materials, and the like. Further, the outer wall portion 21 has a heat insulating layer 23 (see FIG. 2) inside. The heat insulating layer 23 is formed of a heat insulating material such as glass wool. The heat insulating layer 23 is provided over the entire circumference of the outer wall portion 21.

[0025] Subsequently, the structure around the bathroom 15 will be described based on FIG. 2. FIG. 2 is a plan view showing the floor plan around the bathroom 15.

[0026] As shown in FIG. 2, the bathroom 15 is provided at the corner portion 24 of the building 10 in plan view. Therefore, the bathroom 15 is a so-called corner room. The bathroom 15 is formed by a bath unit 25 installed at the corner portion 24. The bath unit 25 is formed in a box shape from a resin material or the like, and the internal space thereof is the bathroom 15. The bath unit 25 is an integrated unit of the floor portion, the ceiling portion, and the wall portion forming the bathroom 15 and the bathtub 25a, and is formed with standardized dimensions. Note that the bath unit 25 corresponds to the equipment unit, and the bathroom 15 corresponds to the unit room.

[0027] The outer wall portion 21 has a pair of wall portions 21a and 21b that form the corner portion 24. The pair of wall portions 21a and 21b are arranged at right angles to each other in plan view. The bathroom 15 is arranged adjacent to each of the pair of wall portions 21a and 21b.

[0028] Adjacent to the bathroom 15 are a washroom 14 and a toilet 16. In the washroom 14, a washstand 14a and a washing machine 14b are installed. The washroom 14 is also used as a dressing room. It is possible to enter and exit the bathroom 15 from the washroom 14 through an entrance / exit 27. Further, the washroom 14 is adjacent to the bathroom 15 in the width direction of the wall portion 21b. In this case, the washroom 14 is adjacent to the bathroom 15 in the thickness direction of the wall portion 21a (corresponding to one of the walls).

[0029] Toilet 16 is adjacent to bathroom 15 in the width direction of wall 21a. In this case, toilet 16 is adjacent to bathroom 15 in the thickness direction of wall 21b (corresponding to the other wall). In addition, the washroom 14 and toilet 16 can be accessed from the corridor 35 extending from LDK 12.

[0030] Of the exterior wall section 21, the portion adjacent to the bathroom 15 (in other words, the bath unit 25) is designated as the first wall section 31. Specifically, in the pair of wall sections 21a and 21b of the exterior wall section 21, the portions adjacent to the bathroom 15 are designated as the first wall section 31. In this embodiment, the thickness t1 of the first wall section 31 is 175 mm.

[0031] Of the exterior wall section 21, the portion not adjacent to the bathroom 15 (in other words, the bath unit 25) is the second wall section 32. The second wall section 32 is the portion of the exterior wall section 21 excluding the first wall section 31. The second wall section 32 is formed by extending (projecting) inward from the first wall section 31, and as a result, the thickness t2 of the second wall section 32 is greater than the thickness t1 of the first wall section 31 (t2>t1). Specifically, the thickness t2 of the second wall section 32 is set to be 1.5 times or more the thickness t1 of the first wall section 31. Note that the second wall section 32 extends inward from the first wall section 31, but does not extend outward from the first wall section 31.

[0032] Furthermore, in this embodiment, the thickness t2 of the second wall section 32 is set to 300 mm. Therefore, in this embodiment, the thickness t2 of the second wall section 32 is 125 mm greater than the thickness t1 of the first wall section 31. To elaborate on this point, in this building 10, the design module is set to a 125 mm pitch. And, in this embodiment, the thickness t2 of the second wall section 32 is made larger than the thickness t1 of the first wall section 31 by the pitch dimension of the design module (125 mm).

[0033] The thickness t4 of the insulation layer 23 of the second wall section 32 (hereinafter referred to as insulation layer 23b) is greater than the thickness t3 of the insulation layer 23 of the first wall section 31 (hereinafter referred to as insulation layer 23a) (t4>t3). More specifically, the thickness t4 of the insulation layer 23b of the second wall section 32 is 1.5 times or more the thickness t3 of the insulation layer 23a of the first wall section 31. Also, the difference between the thickness t4 of the insulation layer 23b of the second wall section 32 and the thickness t3 of the insulation layer 23a of the first wall section 31 is the same as the difference between the thickness t2 of the second wall section 32 and the thickness t1 of the first wall section 31 (t4-t3=t2-t1).

[0034] As described in detail above, the configuration of this embodiment provides the following excellent effects.

[0035] • Of the exterior wall section 21, the portion adjacent to the bathroom 15 is the first wall section 31, and the portion not adjacent to the bathroom 15 is the second wall section 32. The second wall section 32 is formed further inward than the first wall section 31, making it thicker than the first wall section 31, and the thickness of the insulation layer 23 is also greater than that of the first wall section 31. This improves the insulation performance of the exterior wall section 21. Furthermore, in this configuration, since the insulation performance of a portion of the exterior wall section 21 (the first wall section 31) is not enhanced, excessive insulation can be prevented. Therefore, the improvement of insulation performance can be appropriately achieved.

[0036] Furthermore, since the first wall section 31 adjacent to the bathroom 15 (in other words, the bath unit 25) is not extended inward, there is no need to shift the bath unit 25 inward by the amount that would have been required for the extension. Therefore, the impact on room planning, such as the narrowing of the room adjacent to the bathroom 15 due to shifting the bath unit 25, can be minimized. Thus, as described above, it is possible to appropriately improve insulation performance while minimizing the impact on room planning.

[0037] The bathroom 15 is a corner room adjacent to a pair of walls 21a and 21b that are perpendicular to each other in the exterior wall 21. In this configuration, if the entire perimeter of the exterior wall 21 is extended inward to increase its thickness, each of the pair of walls 21a and 21b will be extended inward, which may necessitate shifting the bath unit 25 in two directions. Therefore, it is thought that this will have a significant impact on the room planning.

[0038] In this respect, in the above embodiment, each portion of the pair of wall sections 21a and 21b adjacent to the bathroom 15 is a first wall section 31 with a smaller thickness, that is, a first wall section 31 that does not extend inward towards the interior. This makes it possible to appropriately improve the thermal insulation performance while minimizing the impact on the room planning in a configuration where the bathroom 15 is a corner room.

[0039] In the above embodiment, the washroom 14 is adjacent to the bathroom 15 in the thickness direction of the wall 21a, and the toilet 16 is adjacent to the bathroom 15 in the thickness direction of the wall 21b. Therefore, if the bath unit 25 is shifted in two directions by extending the pair of walls 21a and 21b inward, the washroom 14 and toilet 16 will become narrower. Since the washroom 14 and toilet 16 are already small spaces, further narrowing would likely lead to inconveniences such as poor usability. It is also conceivable to shift the washroom 14 and toilet 16 by the amount they are extended in order to secure space for them, but in that case, it is thought that the planning of other rooms would be greatly affected.

[0040] In this respect, in the above embodiment, as described above, each portion of the pair of wall sections 21a and 21b adjacent to the bathroom 15 is a first wall section 31 with a smaller thickness, that is, a first wall section 31 that does not extend inward towards the interior. This makes it possible to appropriately improve thermal insulation performance while minimizing the impact on the room layout in a configuration where the washroom 14 and toilet 16 are adjacent to the bathroom 15, which is located in a corner room.

[0041] The present invention is not limited to the embodiments described above, and may be implemented, for example, as follows.

[0042] In the above embodiment, the bathroom 15 was a corner room adjacent to a pair of mutually orthogonal wall sections 21a and 21b of the exterior wall section 21. However, it is also possible to have a configuration in which the bathroom 15 is adjacent to only one of the pair of wall sections 21a and 21b. Therefore, the present invention may be applied to such a configuration.

[0043] In the above embodiment, a bathroom 15 formed by a bath unit (corresponding to an equipment unit) was provided as a unit room adjacent to the exterior wall 21. However, it is also conceivable that a room other than a bathroom may be provided as a unit room adjacent to the exterior wall 21. Therefore, the present invention may be applied in such cases as well.

[0044] • In the above embodiment, the present invention was applied to a modular building constructed using a modular construction method, but the present invention may also be applied to buildings constructed using other methods such as steel frame construction or conventional construction methods. Also, in the above embodiment, the present invention was applied to a detached house, but the present invention may also be applied to a dwelling unit in an apartment building. Furthermore, the present invention may not be limited to houses, but may also be applied to accommodation facilities (corresponding to buildings) such as hotels. [Explanation of Symbols]
