Mode for Carrying Out the Invention

[0010] [Embodiment] Hereinafter, the installation structure according to the embodiment will be described with reference to the drawings. However, the following embodiment is only one of various embodiments of the present disclosure. The following embodiment can be variously modified according to design and the like as long as the object of the present disclosure can be achieved. Also, each drawing described in the following embodiment is a schematic diagram, and the ratio of the size and thickness of each component in the drawing does not necessarily reflect the actual dimensional ratio.

[0011] (Overview) The structure 1 for mounting a facility of the present invention is a structure for mounting a facility 2 on a building, and includes a plurality of rail members 3, 3... provided parallel to each other on the foundation 20 of the building, and a plurality of building boards 10, 10... provided between adjacent rail members 3, 3. The rail member 3 has an installation portion 31 for installing the facility 2 and a leg portion 32 in contact with the foundation 20. The installation portion 31 protrudes outside the plurality of building boards 101, 101... overlapping the outdoor side of the leg portion 32. Thereby, the structure 1 for mounting a facility can suppress water leakage in the building. In the following description, the "front-rear direction" means the direction along the roof slope and corresponds to the so-called water flow direction. The "left-right direction" means the direction orthogonal to the front-rear direction. The "up-down direction" means the vertical direction in both the front-rear direction and the left-right direction. That is, the "outdoor side" means the upper side with reference to the building, and the "indoor side" means the lower side with reference to the building. The "outer side" means the direction away from the center line O of the rail member 3 in the direction along the left-right direction, and conversely, the "inner side" means the direction approaching the center line O of the rail member 3 in the direction along the left-right direction. These directions are only used for convenience of explanation, and thus do not limit the embodiments of the present invention in any way.

[0012] (Details) In this embodiment, the building is a roof. Therefore, in this embodiment, the structure 1 for mounting a facility for mounting the facility 2 on the roof will be described.

[0013] <Facility> The structure 1 for mounting a facility can install facilities 2 such as solar panels, water heaters, and antennas on the roof using the rail members 3. In this embodiment, the facility 2 is a rectangular solar panel. The facility 2 (solar panel) has a front end 21 in the front-rear direction and a rear end 22 in the front-rear direction. In FIG. 1, one facility 2 (solar panel) is installed on the roof, but two or more may be installed.

[0014] <Rail member> The rail member 3 is formed to be long in the front-rear direction and short in the left-right direction (see Fig. 2). The material of the rail member 3 is not particularly limited, and examples include aluminum, stainless steel, or steel with rust prevention treatment. For example, the rail member 3 is formed by bending a plate-shaped member having the above material.

[0015] The shape of the rail member 3 is not particularly defined, but a symmetric shape is preferable. In this case, there are advantages such as it being easy to install the fixing member 4 described later on the installation portion 31. Therefore, in the present embodiment, the rail member 3 is formed to be line-symmetric with respect to the center line O as the axis of symmetry (see Fig. 2B).

[0016] The rail member 3 has an installation portion 31 for installing the installed object 2 and a pair of leg portions 32, 32 that contact the roof base 20 (see Fig. 2). The installation portion 31 is formed to protrude upward, that is, toward the outdoor side, from the end portion 34 of the leg portion 32 closer to the center line O. The left leg portion 32 is formed to extend leftward along the left-right direction from the end portion 34 of the leg portion 32 closer to the center line O. The right leg portion 32 is formed to extend rightward along the left-right direction from the end portion 34 of the leg portion 32 closer to the center line O. Also, as described above, in the present embodiment, the rail member 3 is formed to be line-symmetric with respect to the center line O as the axis of symmetry. Therefore, the pair of leg portions 32, 32 are positioned symmetrically with respect to the center line O as the axis of symmetry. Further, the rail member 3 has a water stop portion 33 at the tip end portion on the side far from the center line O of the leg portion 32. Thereby, water leakage in the roof can be more suppressed.

[0017] In addition, in the present embodiment, the installation portion 31 has an upper portion 36 and a pair of side portions 37, 37. The upper portion 36 is a portion located on the upper side in the installation portion 31, and in the present embodiment, it is formed in a planar shape. The side portions 37, 37 are portions that extend so as to connect each of the end portions 35, 35 located at both ends of the upper portion 36 and the inner end portions 34, 34 of the leg portions 32, respectively. The side portion 37 is formed in a flat surface shape. Also, as described above, in the present embodiment, the rail member 3 is formed to be line-symmetric with respect to the center line O as the axis of symmetry. Therefore, the pair of side portions 37, 37 are symmetrically positioned with respect to the center line O as the axis of symmetry.

[0018] <Building board> As described above, the building is a roof. Therefore, in the present embodiment, the building board 10 is a roof board 10. The roof board 10 is not particularly limited, and examples include slate and the like. More specifically, it can be appropriately selected and used from plate-like members such as adhesive board systems, cement systems, and metal systems. More specifically, as the roof board 10, Color Best (registered trademark), Colonial (registered trademark), etc. can be used. The roof board 10 is provided with fastening holes 11. By driving a fastener such as a nail into the fastening holes 11, the roof board 10 can be fixed to the roof base 20. Note that the fastening holes 11 are not provided for the purpose of inserting the fixture 30 provided for fixing the rail member 3.

[0019] <Roof base> As described above, the building is a roof. Therefore, in the present embodiment, the base 20 is a roof base 20. For example, the roof base 20 includes a surface material and a rafter that supports the surface material.

[0020] <Structure for mounting a fixture> As described above, the structure 1 for mounting a fixture includes a plurality of rail members 3, 3,... provided so as to be parallel to each other on the roof base 20 of the building, and a plurality of roof boards 10, 10,... arranged on the roof base 20.

[0021] In this embodiment, the plurality of rail members 3, 3... include a pair of adjacent rail members 3, 3. Each of the pair of rail members 3, 3 is provided so as to be spaced apart in the left - right direction and parallel to each other on the roof base 20. That is, the pair of adjacent rail members 3, 3 are provided without shifting in the left - right direction and the front - rear direction (see Fig. 1).

[0022] Also, in each rail member 3, fasteners 30, 30 are driven into the legs 32, 32 of the respective rail member 3, whereby the rail member 3 and the roof base 20 are fixed by the fasteners 30, 30. When fixing the rail member 3 to the roof base 20, the fastener 30 is not inserted when the roof panel 10 is interposed between the rail member 3 and the roof base 20.

[0023] The roof panels 10, 10... arranged on the roof base 20 are provided between a pair of adjacent rail members 3, 3. As shown in Fig. 1, in this embodiment, the roof panels 10, 10... provided between a pair of adjacent rail members 3, 3 are not arranged in the left - right direction but are provided so as to partially overlap in the front - rear direction. At this time, each of the end portions located in the left - right direction of the roof panels 10, 10... provided between a pair of adjacent rail members 3, 3 overlaps with the respective legs 32, 32 of the pair of rail members 3, 3 (see Fig. 1). Also, the roof panels 10, 10... arranged on the roof base 20 include a plurality of roof panels 101, 101... that overlap the outdoor side of the legs 32. Also, the roof panels 10, 10... may include roof panels 102, 102... that do not overlap on the outdoor side of the legs 32, 32... of the plurality of rail members 3, 3... In this embodiment, these roof panels 102, 102... are not located between a pair of adjacent rail members 3, 3.

[0024] In addition, in the present embodiment, the roof plates 10, 10... provided between adjacent rail members 3, 3 are arranged in a continuous joint pattern (generally referred to as ribbed roofing in the case of a roof). In other words, the roof plates 10, 10... provided between adjacent rail members 3, 3 are not arranged in a staggered pattern. Further, in the present embodiment, among the plurality of roof plates 101, 101... overlapping the outdoor side of the leg portion 32, the roof plates 101, 101... not between a pair of adjacent rail members 3, 3 are also arranged in a continuous joint pattern (see FIG. 1). Note that not all of the roof plates 10, 10... arranged on the roof are arranged in a continuous joint pattern. For example, the roof plates 102, 102... may not be arranged in a continuous joint pattern.

[0025] Further, the installation portion 31 protrudes outside the outdoor side of the plurality of roof plates 101, 101... overlapping the outdoor side of the leg portion 32. Thereby, the installation object 2 can be easily attached to the rail member 3.

[0026] Furthermore, a fixing member 4 for attaching the installation object 2 (solar panel) can be installed on the rail member 3. Examples of the material of the fixing member 4 include metals such as stainless steel. The fixing member 4 includes a base member 41 that directly contacts the rail member 3 and a pressing member 42 attached to the base member 41 (see FIGS. 3 and 4). The base member 41 has a U-shaped clamping portion 411 when viewed from a direction along the front-rear direction opening downward. The base member 41 is installed so as to clamp the installation portion 31 with the clamping portion 411. At this time, the base member 41 may include a bolt 413 that penetrates the clamping portion 411 and a nut 415 that tightens the bolt 413. By tightening the bolt 413 with the nut 415, the base member 41 can be firmly fixed to the installation portion 31. Further, the base member 41 has a connecting portion 412 on the clamping portion 411. A through hole is provided in the connecting portion 412, and a stud bolt 414 is inserted into the hole. Another member such as the pressing member 42 can be attached to the stud bolt 414.

[0027] The pressing member 42 includes an end pressing member 43 that supports the front end portion 21 of the installed object 2 (solar panel), and an intermediate pressing member 44 that supports the rear end portion 22 of the installed object 2 (solar panel). In the present embodiment, for one installed object 2 (solar panel), a pair of end pressing members 43, 43 and a pair of intermediate pressing members 44, 44 are used. Note that the intermediate pressing member 44 not only supports the installed object 2 (solar panel) in front of the intermediate pressing member 44, but also can support another installed object 2 if there is one behind it. For example, when another installed object 2 (solar panel) is further arranged behind the intermediate pressing member 44, the intermediate pressing member 44 can support the front end portion 21 of the other installed object 2 (solar panel).

[0028] The end pressing member 43 has a bottom surface 431 that overlaps with the connection portion 412 of the base member 41, and a side surface 432 that contacts the end portion 21 of the installed object 2 (solar panel). The side surface 432 may have an extension portion 433 that extends so as to overlap the upper surface of the installed object 2 (solar panel), whereby the installed object 2 (solar panel) can be supported more stably. Further, a through hole is provided in the bottom surface 431. A stud bolt 414 provided in the base member 41 is inserted into the through hole. Then, in order to fix the end pressing member 43 to the base member 41, the stud bolt 414 is tightened with a nut 415 or the like.

[0029] Further, the intermediate pressing member 44 has a bottom surface 441 that overlaps with the connection portion 412 of the base member 41, and a pair of side surfaces 442, 442 that contact either the end portions 21, 22 of the installed object 2 (solar panel). Each of the side surfaces 442, 442 may have extension portions 443, 443 that extend so as to overlap the upper surface of the installed object 2 (solar panel), whereby the installed object 2 (solar panel) can be supported more stably. Further, a through hole is provided in the bottom surface 441. A stud bolt 414 provided in the base member 41 is inserted into the through hole. Then, in order to fix the intermediate pressing member 44 to the base member 41, the stud bolt 414 is tightened with a nut 415 or the like.

[0030] Note that, in order to support the front end 21 of the installation object 2 (solar panel), it is not necessarily required to use the end pressing member 43, and in order to support the rear end 22 of the installation object 2 (solar panel), it is not necessarily required to use the intermediate pressing member 44. Appropriate members can be selected according to the appropriate usage mode.

[0031] <Function and Effect> In the present invention, when fixing the rail member 3 to the roof base 20, the fixture 30 is not inserted through the roof panel 10. Therefore, in order to fix the rail member 3 to the roof, it is possible to avoid making holes in the roof panel 10. Thereby, the structure 1 for mounting an installation object can suppress water leakage in the roof.

[0032] Further, since the plurality of roof panels 10, 10... provided between at least adjacent rail members 3, 3 are arranged in a continuous joint state, the rail member 3 can be constructed so as to extend to the gable portion. Thereby, since the number of installed rail members 3 can be reduced, there is also an advantage that workability is easily improved.

[0033] <Construction Method> The construction structure of the structure 1 for mounting an installation object will be described.

[0034] First, a plurality of rail members 3, 3... are provided so as to be spaced apart in the left - right direction and parallel to each other on the roof base 20. At this time, for a pair of adjacent rail members 3, 3 among the plurality of rail members 3, 3..., they are arranged so as not to shift in the left - right direction and the front - rear direction. Then, after arranging the rail members 3, 3... on the roof base 20, the fixtures 30, 30 are inserted through the pair of leg portions 32, 32 of the rail member 3. Thereby, the roof base 20 and the rail member 3 are fixed.

[0035] Subsequently, the roof panel 10 is placed on the roof base 20. After fixing the rail member 3 to the roof base 20, the roof panel 10 is placed. Regarding the plurality of roof panels 10, 10... provided between a pair of adjacent rail members 3, 3, they are arranged in a continuous joint manner. Also, the plurality of roof panels 10, 10... are arranged such that the installation portion 31 protrudes to the outdoor side more than the plurality of roof panels 101, 101... that are arranged overlapping the outdoor side of the leg portion 32. Note that the arrangement method of the roof panels 102, 102... that do not overlap on the outdoor side of the leg portion 32 of the rail member 3 is not particularly limited. Therefore, the roof panels 102, 102... may be arranged in a continuous joint manner or not.

[0036] After placing the roof panels 10, 10... on the roof base 20, fixing members 4, 4... are installed on the rail members 3, 3.... First, according to the location where the installation object 2 is to be attached, a base member 41 is installed on the installation portion 31 of the rail member 3. As described above, in this embodiment, for the installation object 2 (solar panel), the base member 41 is installed so that the front end 21 of the installation object 2 (solar panel) can be supported at two locations and the rear end 22 can be supported at two locations. Also, when installing the base member 41, after sandwiching the installation portion 31 with the sandwiching portion 411 of the base member 41, the bolt 413 is tightened with the nut 415.

[0037] Next, attach the pressing member 42 to the base member 41. First, attach end pressing members 43, 43 to each of the pair of base members 41, 41 installed near the front end 21 of the installed object 2 (solar panel). At this time, insert the stud bolt 414 through the through hole provided in the bottom surface 431 of the end pressing member 43 and tighten it with a nut 415 or the like. In this way, attach the end pressing members 43, 43 to each of the pair of base members 41, 41. In the same procedure, attach intermediate pressing members 44, 44 to each of the pair of base members 41, 41 installed near the rear end 22 of the installed object 2 (solar panel). At this time, insert the stud bolt 414 through the through hole provided in the bottom surface 441 of the intermediate pressing member 44 and tighten it with a nut 415 or the like. In this way, attach the intermediate pressing members 44, 44 to each of the pair of base members 41, 41.

[0038] Following the above procedure, after installing the fixing member 4 on the installation portion 31 of the rail member 3, place the installed object 2 (solar panel) on the fixing member 4. If the front end 21 of the installed object 2 (solar panel) is hooked on the end pressing members 43, 43 and the rear end 22 is hooked on the intermediate pressing members 44, 44, the installed object 2 (solar panel) can be placed.

[0039] [Modification Example] The present invention is not limited to the above-described embodiment. The above-described embodiment can be variously modified according to the design and the like as long as the object of the present invention can be achieved. Hereinafter, modification examples of the above-described embodiment will be listed.

[0040] (Modification Example 1) In the above-described embodiment, the installed object 2 was a solar panel, but it is not limited thereto. That is, the structure 1 for installing an installed object can use the rail member 3 to install not only solar panels but also installed objects 2 such as water heaters and antennas on the roof.

[0041] (Modification Example 2) In the above embodiment, the pair of side portions 37, 37 were flat surfaces extending in the vertical direction, but it is not limited to this. For example, the pair of side portions 37, 37 may have a plurality of bent portions and have a shape bent at the bent portions. In this case, these side portions 37, 37 will have a plurality of flat portions.

[0042] For example, in the rail member 3 shown in FIGS. 5A and 5B, the pair of side portions 37, 37 have a shape bent at each of the first bent portions 391, 391 and the second bent portions 392, 392. Therefore, these side portions 37, 37 have the first flat portions 371, 371, the second flat portions 372, 372, and the third flat portions 373, 373. Further, compared with the rail member 3 shown in FIGS. 5A and 5B, in the rail member 3 shown in FIG. 5C, the pair of side portions 37, 37 further have a third bent portion 393, 393 in addition to the first bent portions 391, 391 and the second bent portions 392, 392. Therefore, these side portions 37, 37 have the first flat portions 371, 371, the second flat portions 372, 372, the third flat portions 373, 373, and in addition, the fourth flat portions 374, 374. Regarding the bent portions of the pair of side portions 37, 37, in order from the closest to the end portions 35, 35 of the upper portion 36, they are the first bent portions 391, 391, the second bent portions 392, 392, the third bent portions 393, 393, ···, and similarly, regarding the flat portions of the pair of side portions 37, 37, in order from the closest to the end portions 35, 35 of the upper portion 36, they are the first flat portions 371, 371, the second flat portions 372, 372, the third flat portions 373, 373, ···.

[0043] In FIG. 5A, the first bent portions 391, 391 are located outside and below the end portions 35, 35 that connect via these first bent portions 391, 391 and the first flat portions 371, 371. Therefore, the first flat portions 371, 371 extend outward and downward from the end portions 35, 35. The second bent portions 392, 392 are located inside and below the first bent portions 391, 391 that connect via these second bent portions 392, 392 and the second flat portions 372, 372. Therefore, the second flat portions 372, 372 extend inward and downward from the first bent portions 391, 391. The end portions 34, 34 and the second bent portions 392, 392 that connect via these end portions 34, 34 and the third flat portions 373, 373 are positioned without shifting in the left-right direction. Therefore, the third flat portions 373, 373 extend downward along the vertical direction from the second bent portions 392, 392. The rail member 3 shown in FIG. 5A is formed to be line-symmetrical with respect to each other about the center line O as the axis of symmetry. Therefore, each of the first flat portions 371, 371, each of the second flat portions 372, 372, and each of the third flat portions 373, 373 are positioned line-symmetrical with respect to each other about the center line O as the axis of symmetry.

[0044] In FIG. 5B, the first bent portions 391, 391 and the end portions 35, 35 connected via these first bent portions 391, 391 and the first flat portions 371, 371 are positioned without shifting in the left - right direction. Therefore, the first flat portions 371, 371 extend downward in a direction along the vertical direction from the end portions 35, 35. The second bent portions 392, 392 are positioned inside the first bent portions 391, 391 connected via these second bent portions 392, 392 and the second flat portions 372, 372. And the second bent portions 392, 392 and the first bent portions 391, 391 connected via these and the second flat portions 372, 372 are positioned without shifting in the vertical direction. Therefore, the second flat portions 372, 372 extend inward in a direction along the left - right direction from the first bent portions 391, 391. The end portions 34, 34 and the second bent portions 392, 392 connected via these end portions 34, 34 and the third flat portions 373, 373 are positioned without shifting in the left - right direction. Therefore, the third flat portions 373, 373 extend in a direction along the vertical direction from the second bent portions 392, 392. The rail member 3 shown in FIG. 5B is formed to be line - symmetric with each other with the center line O as the axis of symmetry. Therefore, each of the first flat portions 371, 371, each of the second flat portions 372, 372, and each of the third flat portions 373, 373 are positioned line - symmetric with each other with the center line O as the axis of symmetry.

[0045] In FIG. 5C, the first bent portions 391, 391 and the end portions 35, 35 connected via these first bent portions 391, 391 and the first flat portions 371, 371 are positioned without shifting in the left-right direction. Therefore, the first flat portions 371, 371 extend in a direction along the vertical direction from the end portions 35, 35. The second bent portions 392, 392 are positioned outside and below the first bent portions 391, 391 connected via these second bent portions 392, 392 and the second flat portions 372, 372. Therefore, the second flat portions 372, 372 extend outside and downward from the first bent portions 391, 391. The third bent portions 393, 393 are positioned inside and below the second bent portions 392, 392 connected via these third bent portions 393, 393 and the third flat portions 373, 373. Therefore, the third flat portions 373, 373 extend inside and downward from the second bent portions 392, 392. The third bent portions 393, 393 and the end portions 34, 34 connected via these third bent portions 393, 393 and the fourth flat portions 374, 374 are positioned without shifting in the left-right direction. Therefore, the fourth flat portions 374, 374 extend downward in a direction along the vertical direction from the third bent portions 393, 393. The rail member 3 shown in FIG. 5C is formed to be line-symmetrical with respect to the center line O as the axis of symmetry. Therefore, each of the first flat portions 371, 371, each of the second flat portions 372, 372, each of the third flat portions 373, 373, and each of the fourth flat portions 374, 374 are positioned line-symmetrical with respect to the center line O as the axis of symmetry.

[0046] The installation portion 31 having a shape as shown in FIGS. 5A, 5B, and 5C has a part of a pair of side portions 37, 37 protruding outside the rail member 3. Therefore, the protruding portion is likely to be caught by the sandwiching portion 411 of the base member 41. As a result, the fixing member 4 is less likely to come off from the installation portion 31.

[0047] The shape of the rail member 3 does not have to be symmetric about the left and right. For example, the side portion 37 located on the left side in the left - right direction may be a flat surface extending along the up - down direction, and the side portion 37 located on the right side in the left - right direction may have a shape having a plurality of flat portions (see Fig. 5D). Also, the installation portion 31 may have a shape in which a part of the upper portion 36 protrudes outside the side portions 37, 37 (see Fig. 5E). For example, by bending the upper portion 36 so that a part of the upper portion 36 comes outside the end portions 35, 35, the installation portion 31 can be formed into the shape as shown in Fig. 5E.

[0048] In the above - described embodiment, the installation portion 31 is composed of the upper portion 36 and a pair of side portions 37, 37, but it is not limited to this. For example, the installation portion 31 may not have the upper portion 36 and may be composed of only the side portion 37 (see Fig. 5F).

[0049] (Modification 3) The installation portion 31 may have holes 38 through which the bolts 413 provided on the base member 41 can be inserted (see Fig. 6). In this case, by inserting the bolts 413 of the base member 41 into the holes 38, the base member 41 can be fixed to the installation portion 31. As a result, the fixing member 4 is less likely to come off from the installation portion 31.

[0050] (Modification 4) The rail member 3 does not have to be directly fixed to the roof base 20 by the fixture 30. For example, by installing a hanger 50 on the roof base 20 and installing the rail member 3 on the hanger 50, the rail member 3 may be fixed to the roof base 20 (see Fig. 7A). The hanger 50 has a locking portion 51 formed by bending the end of the hanger 50 at an acute angle, and the rail member 3 can be installed on the hanger 50 by hooking the water - stop portion 33 of the rail member 3 on the locking portion 51.

[0051] The leg portion 32 of the rail member 3 may be provided with ribs 321 (see FIG. 7B). When the fixture 30 is inserted through the leg portion 32 as in the present embodiment, a large stress may be generated in the leg portion 32. At this time, since the ribs 321 are provided on the leg portion 32, even if a large stress is generated in the leg portion 32, deformation of the leg portion 32 can be suppressed. Further, the ribs 321 can suppress the intrusion of rainwater.

[0052] The leg portion 32 of the rail member 3 may be provided with a sealer 60 (see FIG. 7C). In this case, water leakage in the building can be further suppressed.

[0053] (Modification 5) In the above embodiment, as shown in FIG. 1, the plurality of building plates 10, 10... provided between a pair of adjacent rail members 3, 3 were arranged in a continuous joint manner, but the present invention is not limited to this. For example, when a plurality of building plates 10, 10... are arranged side by side in the left - right direction between a pair of rail members 3, 3, a part of those building plates 10, 10... may be cut, for example, to a width of 1 / 2 and arranged in a staggered pattern.

[0054] (Modification 6) In the above embodiment, as shown in FIG. 1, only a pair of adjacent rail members 3, 3 were provided, but the present invention is not limited to this. For example, a large number of rail members 3, 3... corresponding to the left - right width dimension of the roof plate 10 may be provided on the entire surface (excluding the eaves) of the roof base 20 on one side (the south side) of the gable roof, and the roof plates 10, 10... may be arranged in a continuous joint manner (strip roofing) between the opposing rail members 3, 3. Thereby, a wider range for attaching the installation object 2 can be secured.

[0055] (Modification 7) In the embodiment, the roof has been described, but the present invention is not limited to the roof and can be applied to buildings such as outer walls, inner walls, and fences. For example, in the case of an outer wall, as a general example, a sill can be cited as the base, and siding can be cited as the building plate 10.

[0056] [Aspect] As is apparent from the above embodiments, the present invention includes the following aspects.

[0057] The structure 1 for mounting a fixture in the first aspect is a structure for mounting a fixture 2 on a building, and includes a plurality of rail members 3, 3,... provided parallel to each other on the foundation 20 of the building, and a plurality of building boards 10, 10,... provided between adjacent rail members 3, 3. The rail member 3 has an installation portion 31 for installing the fixture 2 and a leg portion 32 in contact with the foundation 20. The installation portion 31 protrudes outside the building more than a plurality of building boards 101, 101,... overlapping on the outdoor side of the leg portion 32.

[0058] According to this aspect, the structure 1 for mounting a fixture can suppress water leakage in the building.

[0059] The structure 1 for mounting a fixture in the second aspect is, in the first aspect, a plurality of building boards 10, 10,... provided at least between adjacent rail members 3, 3 are arranged in a through-joint shape.

[0060] The construction method of the structure 1 for mounting a fixture in the third aspect is a construction method of the structure 1 for mounting a fixture 2 on a building. The structure 1 for mounting a fixture includes a plurality of rail members 3, 3,... provided parallel to each other on the foundation 20 of the building, and a plurality of building boards 10, 10,... provided between adjacent rail members 3, 3. The rail member 3 has an installation portion 31 for installing the fixture 2 and a leg portion 32 in contact with the foundation 20. After fixing the rail member 3 to the foundation 20 of the building, a plurality of building boards 10, 10,... are arranged overlapping on the outdoor side of the leg portion 32 so that the installation portion 31 protrudes outside the building more than the plurality of building boards 10, 10,...
