Description

[Technical field]

[0001] The present disclosure relates to eaves members, buildings, and methods for constructing roof eaves. [Background technology]

[0002] An eaves edge member that is placed at the eaves edge is known (for example, Patent Document 1). As an example, the eaves edge member shown in Patent Document 1 (called an eaves edge cover in the document) has a gable section, a drip edge section, and a rigidity retaining section that are integrally formed. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 05-081427 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when constructing a roof, the ends of the sheathing boards or the ends of the rafters may not be aligned at the eaves due to variations in the dimensions of the sheathing boards and rafters. In this case, it is difficult to position the eaves end components perpendicular to the rafters. When there is variation in the dimensions of the sheathing boards and rafters, it is difficult to position the eaves end components in the appropriate position. [Means for solving the problem]

[0005] (1) The eaves member that solves the above problem is an eaves member that is placed at the eaves of a roof that has a sheathing board and rafters, and includes a main body that covers the end of the sheathing board and the end face of the rafters, and an adjustment part that extends from the main body in the direction of the slope of the roof and contacts at least one of the rafters and the sheathing board to adjust the position of the main body. With this configuration, the position of the main body can be adjusted by the adjustment part, making it easy to place the eaves member in an appropriate position.

[0006] (2) In the eaves member described in (1) above, the adjustment part includes a first adjustment part that contacts the upper surface of the sheathing board and a second adjustment part that contacts the lower surface of the rafters. With this configuration, the adjustment part contacts the upper surface of the sheathing board and the lower surface of the rafters, so that the adjustment part can be easily moved along the slope of the roof. By moving the adjustment part along the slope of the roof, the position of the eaves member can be adjusted so that the eaves member is perpendicular to the rafters.

[0007] (3) In the eaves member described in (1) or (2) above, the adjustment portion includes an attachment portion that is attached to the rafter, the attachment portion having a temporary fixing hole, and the temporary fixing hole is a long hole extending in the gradient direction.

[0008] According to this configuration, the eaves member can be attached to at least one of the roof board and the rafter by driving the support into the temporary fixing hole. The support is, for example, a nail, a screw, etc. Since the temporary fixing hole is an elongated hole extending in the direction of the roof slope, the position of the main body can be finely adjusted even after the support is driven into the temporary fixing hole.

[0009] (4) In the eaves edge member described in (3) above, the mounting portion has a fixing hole different from the temporary fixing hole. With this configuration, the eaves edge member can be attached to at least one of the sheathing board and the rafter by driving a support into the fixing hole. After the support is driven into the temporary fixing hole to fine-tune the position of the main body, the support is driven into the fixing hole, thereby preventing the eaves edge member from shifting in position in the future.

[0010] (5) In the eaves edge member described in (4) above, the fixing holes are perfect circles, and the fixing holes are arranged so as to align with the temporary fixing holes in the gradient direction. With this configuration, since the fixing holes are perfect circles, the support driven into the fixing holes is likely to prevent the eaves edge member from shifting out of position. Also, since the fixing holes are aligned with the temporary fixing holes in the gradient direction, the support driven into the fixing holes is arranged aligned with the support driven into the temporary fixing holes in the gradient direction. Therefore, the support driven into the fixing holes is easily arranged on the same member as the support driven into the temporary fixing holes is arranged.

[0011] (6) In the eaves member described in any one of (1) to (5) above, the main body portion is provided with a drip edge portion covering an end face of the end of the sheathing board, and the drip edge portion has a first drip edge facing the end face of the sheathing board and a second drip edge extending downward from the first drip edge.

[0012] With this configuration, the drip edge covers the end face of the end of the sheathing board, so water is less likely to come into contact with the sheathing board. This can slow down deterioration of the sheathing board due to rain, etc. In addition, because the first drip edge faces the end face of the sheathing board and the second drip edge extends downward from the first drip edge, water flowing over the drip edge can be easily drained away from the roof.

[0013] (7) In the eaves member according to any one of (1) to (6) above, the main body includes a fascia plate portion that covers the end face of the rafter. With this configuration, the fascia plate portion covers the end face of the rafter, thereby protecting the end face of the rafter.

[0014] (8) In the eaves edge member according to any one of (1) to (7) above, the adjustment portion is integrally formed with the main body portion. According to this configuration, the main body portion and the adjustment portion are integrally formed, which can improve manufacturing efficiency.

[0015] (9) A building that solves the above problem is a building having a roof, and is provided with the eaves member according to any one of (1) to (8). With this configuration, the eaves member can be positioned in an appropriate position by adjusting the position of the main body with the adjustment unit, so that the eaves of the roof can be easily constructed.

[0016] (10) A construction method for the eaves edge of a roof that solves the above problems is a construction method for the eaves edge of a roof that includes rafters hung on horizontal beams, a sheathing board, and an eaves edge member, the eaves edge member includes a main body that covers the ends of the sheathing board and the end faces of the rafters, and an adjustment part that extends from the main body in the direction of the slope of the roof, and includes a step of adjusting the position of the main body so that it is arranged parallel to the horizontal beam by moving the adjustment part along at least one of the sheathing board and the rafter in the direction of the slope. With this configuration, since the position of the main body can be adjusted by the adjustment part, it is easy to arrange the eaves edge member so that the main body is parallel to the horizontal beam. Effect of the Invention

[0017] According to the eaves edge member, building, and roof eaves edge construction method disclosed herein, the eaves edge member can be easily positioned in an appropriate position. [Brief description of the drawings]

[0019] <Embodiment> 1 to 6, an explanation will be given of an eaves edge member 10, a building 1, and a method for constructing an eaves edge 5 of a roof 2 according to an embodiment.

[0020] <Eaves material> As shown in FIG. 1 and FIG. 2, a building 1 has a roof 2. Examples of the building 1 include a house, a detached office, a medical facility, and the like. Examples of the roof 2 include a hip roof, a gable roof, a single-shed roof, and the like. In this embodiment, a house with a hip roof is taken as an example. The building 1 includes an eaves member 10. The roof 2 includes rafters 3, a sheathing board 4, and an eaves member 10. As shown in FIG. 5, the rafters 3 are hung on a horizontal beam 6. The horizontal beam 6 is, for example, a beam or a girder. In a plan view, the horizontal beam 6 extends in a first direction D1, and the rafters 3 extend in a second direction D2. The second direction D2 is perpendicular to the first direction D1. The eaves member 10 is disposed at the eaves 5 of the roof 2 including the rafters 3 and the sheathing board 4.

[0021] As shown in FIG. 4, multiple rafters 3 are lined up in the first direction D1. The number of multiple rafters 3 is set according to the length of the roof 2 in the first direction D1. Sheathing boards 4 are attached to the upper surfaces of the rafters 3. As shown in FIG. 1 and FIG. 2, roofing material 2A is attached to the upper surface 4B of the sheathing boards 4. The material of the eaves end member 10 is, for example, aluminum or an aluminum alloy. The eaves end member 10 is formed by aluminum drawing or aluminum extrusion. When the eaves end member 10 is formed of aluminum or an aluminum alloy, the eaves end member 10 can be made lighter than the steel eaves end member 40, making it easier to transport, install, etc.

[0022] <Main body> As shown in Figs. 2 and 4, the eaves member 10 includes a main body 11 and an adjustment portion 20. The main body 11 covers the end 4A of the sheathing board 4 and the end face 3A of the rafter 3. The main body 11 is configured as a single member. The main body 11 extends in the first direction D1 so as to cover the end faces 3A of the multiple rafters 3 lined up in the first direction D1. The length of the main body 11 in the first direction D1 is set according to the length of the roof 2 in the first direction D1, the weight of the eaves member 10, and the like. The number of rafters 3 whose end faces 3A are covered by the main body 11 is set according to the length of the main body 11 in the first direction D1.

[0023] In the example of Fig. 2, the eaves member 10 is arranged so that a space is provided between the end face 3A of the rafter 3 and the main body 11 when viewed in the first direction D1. Fig. 2 shows an example showing the positional relationship between one of the multiple rafters 3 and the main body 11. In other words, the multiple rafters 3 may include a rafter 3 in which a space is provided between the end face 3A and the main body 11, and a rafter 3 in which the end face 3A and the main body 11 are in contact with each other.

[0024] In the example of Fig. 2, the eaves member 10 is arranged so that, as viewed in the first direction D1, the underside of the end 4A of the sheathing board 4 contacts the main body 11 and a space is provided between the end 4C of the sheathing board 4 and the main body 11. In the cross-sectional view of Fig. 2, the underside of the end 4A of the sheathing board 4 contacts the main body 11, but in a cross-sectional view at a position different from Fig. 2 in the first direction D1, the underside of the end 4A of the sheathing board 4 does not have to contact the main body 11. Alternatively, in a cross-sectional view at a position different from Fig. 2 in the first direction D1, the end 4C of the sheathing board 4 may contact the main body 11.

[0025] <Hirokomaibu> Main body 11 includes, for example, wide mai 12 that covers at least a portion of upper surface 4B of end 4A of sheathing board 4. Wide mai 12 is positioned so that a space is provided between wide mai 12 and upper surface 4B of end 4A of sheathing board 4. As shown in Figures 1 and 2, a roof material 2A to be attached onto sheathing board 4 is layered on wide mai 12.

[0026] <Draining section> As shown in FIG. 2, the main body 11 includes, for example, a drip edge 13. The drip edge 13 is formed continuously from the wide siding 12. The drip edge 13 covers the end face 4C of the end 4A of the sheathing board 4. The drip edge 13 has a first drip edge 13A and a second drip edge 13B. The first drip edge 13A faces the end face 4C of the sheathing board 4. The second drip edge 13B extends downward from the first drip edge 13A. The first drip edge 13A and the second drip edge 13B are arranged so as not to overlap the sheathing board 4 in a direction perpendicular to the gradient direction DS.

[0027] The first drip 13A is a member for protecting the end surface 4C of the sheathing board 4 from getting wet. The first drip 13A is formed continuously from the wide small siding 12. The first drip 13A is arranged to face the end surface 4C of the sheathing board 4, thereby covering the end surface 4C of the sheathing board 4. The first drip 13A may further cover the upper surface 4B of the end portion 4A of the sheathing board 4. The second drip 13B is a member for draining water from the eaves 5 to the gutter 5A due to rain, etc. The second drip 13B is formed continuously from the first drip 13A. The second drip 13B is arranged to be inclined along the gradient direction DS. The drip section 13 has a third drip 13C formed continuously from the first drip 13A. The third drip 13C is a member for protecting the lower surface of the end portion 4A of the sheathing board 4 from getting wet.

[0028] <Fascia part> The main body 11 includes, for example, a fascia portion 14. In this embodiment, the fascia portion 14 is formed continuously from the third drip edge 13C so as to extend in the vertical direction. The fascia portion 14 covers the end face 3A of the rafter 3. The fascia portion 14 has a fascia plate 14A. The fascia plate 14A extends in the vertical direction and in the first direction D1 so as to face the end faces 3A of the multiple rafters 3 aligned in the first direction D1. The fascia plate 14A may be configured to allow a gutter 5A to be attached.

[0029] The fascia portion 14 includes a ceiling support portion 14B. The ceiling support portion 14B supports the end of the ceiling portion 7 so as to conceal the end of the ceiling portion 7 from below. The ceiling portion 7 is, for example, siding that constitutes part of the exterior wall of the building 1. The ceiling support portion 14B continues from the lower end of the fascia board 14A and extends in the direction opposite to the second direction D2.

[0030] <Adjustment part> The adjustment unit 20 comes into contact with at least one of the rafters 3 and the sheathing board 4, and adjusts the position of the main body unit 11. The adjustment unit 20 is formed integrally with the main body unit 11. The adjustment unit 20 adjusts the position of the main body unit 11 by moving relative to at least one of the rafters 3 and the sheathing board 4 when the eaves end member 10 is not fixed.

[0031] The adjustment unit 20 extends from the main body 11 along the gradient direction DS of the roof 2. A dimension L1 of the adjustment unit 20 in the gradient direction DS is defined as a dimension from a first end 20A of the adjustment unit 20 to a second end 20B of the adjustment unit 20. The dimension L1 of the adjustment unit 20 is, for example, 100 mm or more and 200 mm or less. The adjustment unit 20 includes, for example, a first adjustment unit 21 and a second adjustment unit 22. The first adjustment unit 21 and the second adjustment unit 22 are arranged parallel to each other in the up-down direction.

[0032] The first adjustment part 21 contacts the upper surface 4B of the sheathing board 4. The first adjustment part 21 extends continuously from the wide siding section 12 along the slope direction DS of the roof 2. For example, the first adjustment part 21 has a plate-shaped member. The plate-shaped member of the first adjustment part 21 contacts the upper surface 4B of the end part 4A of the sheathing board 4. When the eaves member 10 is not fixed, the plate-shaped member of the first adjustment part 21 is configured to be able to slide on the upper surface 4B of the sheathing board 4.

[0033] The second adjustment part 22 contacts the underside 3B of the rafter 3. The second adjustment part 22 extends continuously from the fascia part 14 along the slope direction DS of the roof 2. For example, the second adjustment part 22 has a plate-shaped member. The plate-shaped member of the second adjustment part 22 contacts the underside 3B of the rafter 3. When the eaves member 10 is not fixed, the plate-shaped member of the second adjustment part 22 is configured to be able to slide on the underside 3B of the rafter 3.

[0034] As shown in Figures 2 and 3, the adjustment section 20 includes an attachment section 23 that is attached to the rafter 3. The attachment section 23 is provided on both the first adjustment section 21 and the second adjustment section 22. The attachment section 23 may be provided on only one of the first adjustment section 21 and the second adjustment section 22. The attachment section 23 is disposed so as to overlap with the rafter 3 in the first direction D1. The attachment section 23 has a temporary fixing hole 24. The attachment section 23 has a fixing hole 25 that is different from the temporary fixing hole 24. The temporary fixing hole 24 is an elongated hole that extends in the gradient direction DS. The fixing hole 25 is a perfect circle.

[0035] The temporary fixing hole 24 and the fixing hole 25 are through holes provided in the adjustment part 20. The fixing hole 25 is arranged so as to be aligned with the temporary fixing hole 24 in the gradient direction DS of the roof 2. It is sufficient that both the temporary fixing hole 24 and the fixing hole 25 overlap with the rafter 3 in the vertical direction, and the fixing hole 25 does not necessarily have to be aligned with the temporary fixing hole 24 in the gradient direction DS of the roof 2.

[0036] The adjustment part 20 is attached to the rafter 3 by driving the support 30 into the temporary fixing hole 24 and the fixing hole 25. The support 30 is, for example, a screw, a nail, etc. In this manner, the eaves end member 10 is fixed by attaching the adjustment part 20 to the rafter 3, and the position of the eaves end member 10 at the eaves end 5 is determined.

[0037] As shown in Fig. 4, a plurality of temporary fixing holes 24 are aligned in a first direction D1. A plurality of fixing holes 25 are aligned in the first direction D1. Each of the plurality of temporary fixing holes 24 is aligned in the gradient direction DS with a fixing hole 25 close to that temporary fixing hole 24. The plurality of temporary fixing holes 24 are arranged so as to overlap with the plurality of rafters 3 aligned in the first direction D1. Similarly, the plurality of fixing holes 25 are arranged so as to overlap with the plurality of rafters 3 aligned in the first direction D1.

[0038] The length of the temporary fixing hole 24 in the gradient direction DS (hereinafter, gradient length R1) and the diameter R2 of the fixing hole 25 can be set according to the dimensions of the support 30. In one example, the gradient length R1 of the temporary fixing hole 24 is 20 mm. The diameter R2 of the fixing hole 25 is 10 mm. The larger the gradient length R1 of the temporary fixing hole 24, the larger the range in which the position of the main body portion 11 can be finely adjusted after the support 30 is driven into the temporary fixing hole 24.

[0039] The dimension from the first end 20A of the adjustment portion 20 to the first end 24A of the temporary fixing hole 24 is defined as dimension L2. The dimension from the second end 24B of the temporary fixing hole 24 to the first end 25A of the fixing hole 25 is defined as dimension L3. The dimension from the second end 25B of the fixing hole 25 to the second end 20B of the adjustment portion 20 is defined as dimension L4. The dimensions L2, L3, and L4 can be set according to the strength of the rafter 3, the range in which the position of the adjustment portion 20 is adjusted, and the like. The dimension L1, which is the length of the adjustment portion 20 in the gradient direction DS, can be set according to the gradient length R1, the diameter R2, the dimension L2, the dimension L3, and the dimension L4. In one example, the dimension L2 is 10 mm. The dimension L3 is 50 mm. The dimension L4 is 15 mm.

[0040] The temporary fixing holes 24 include, for example, a first through hole 24X of the first mounting portion 23A described later and a third through hole 24Y of the second mounting portion 23B described later. In one example, the first through hole 24X and the third through hole 24Y are long holes whose length in the gradient direction DS is a gradient length R1. The fixing holes 25 include, for example, a second through hole 25X of the first mounting portion 23A described later and a fourth through hole 25Y of the second mounting portion 23B described later. In one example, the second through hole 25X and the fourth through hole 25Y are perfect circles whose diameter is R2.

[0041] The mounting portion 23 includes, for example, a first mounting portion 23A and a second mounting portion 23B. In this embodiment, the first mounting portion 23A is provided on the first adjustment portion 21, and the second mounting portion 23B is provided on the second adjustment portion 22. The first mounting portion 23A has a first through hole 24X as the temporary fixing hole 24 and a second through hole 25X as the fixing hole 25. The second through hole 25X is arranged to be aligned with the first through hole 24X in the gradient direction DS of the roof 2. The second mounting portion 23B has a third through hole 24Y as the temporary fixing hole 24 and a fourth through hole 25Y as the fixing hole 25. The fourth through hole 25Y is arranged to be aligned with the third through hole 24Y in the gradient direction DS of the roof 2.

[0042] 4, in this embodiment, a first through hole 24X and a second through hole 25X are formed in the first adjustment portion 21, and a third through hole 24Y and a fourth through hole 25Y are formed in the second adjustment portion 22. In the first direction D1, the position of the first through hole 24X of the first adjustment portion 21 is equal to the position of the third through hole 24Y of the second adjustment portion 22. In the first direction D1, the position of the second through hole 25X of the first adjustment portion 21 is equal to the position of the fourth through hole 25Y of the second adjustment portion 22.

[0043] <Construction method> A construction method for the eaves 5 of the roof 2 according to the embodiment will be described with reference to Figures 4 to 6. Figures 5 and 6 are plan views of the roof 2 during construction of the roof 2. In Figures 5 and 6, the sheathing boards 4 are drawn with two-dot chain lines to make the rafters 3 easier to see.

[0044] The construction method includes the following steps. In the steps, the adjustment unit 20 moves along at least one of the sheathing board 4 and the rafters 3 in the gradient direction DS, thereby adjusting the position of the main body 11 so that it is disposed parallel to the horizontal beam 6. In this embodiment, the first adjustment unit 21 moves along the sheathing board 4, and the second adjustment unit 22 moves along the rafters 3.

[0045] In one example, the construction method includes a first step, a second step, a third step, a fourth step, and a fifth step. The first step is a step of placing the eaves edge member 10 at the eaves edge 5. In the first step, the eaves edge member 10 is placed at the eaves edge 5 so that the position of the mounting portion 23 in the first direction D1 matches the positions of the multiple rafters 3 lined up in the first direction D1. After the mounting portion 23 is aligned with the rafters 3 as shown in FIG. 5, the eaves edge member 10 is moved in the direction opposite to the gradient direction DS, thereby placing the eaves edge member 10 at the eaves edge 5. In the first step, after the eaves edge member 10 is placed at the eaves edge 5, the adjustment portion 20 may be moved along the first direction D1 to align the mounting portion 23 with the position of the rafter 3.

[0046] The second step is a step in which the position of the main body part 11 is adjusted by the adjustment part 20. In the second step, the adjustment unit 20 is moved in the gradient direction DS along the sheathing boards 4 and the rafters 3, thereby adjusting the position of the main body 11 so that the fascia boards 14 are arranged parallel to a line along the first direction D1. Since the fascia boards 14 are arranged parallel to a line along the first direction D1 in this manner, the main body 11 is arranged parallel to the horizontal beams 6.

[0047] The third step is a step in which the eaves end member 10 is temporarily fixed by the first attachment portion 23A. In the third step, the support 30 is driven into the first through hole 24X of the first attachment portion 23A, and the movement of the adjustment portion 20 is restricted, whereby the main body portion 11 is temporarily fixed in the position arranged in the second step. Since the first through hole 24X is an elongated hole, even in a state in which the support 30 is driven into the first through hole 24X, the adjustment portion 20 can move according to the length of the gradient length R1 of the first through hole 24X. In a state in which the support 30 is driven into the multiple first through holes 24X aligned in the first direction D1, the position of the main body portion 11 is adjusted, thereby finely adjusting the position of the main body portion 11.

[0048] The fourth step is a step in which the eaves end member 10 is fixed by the first attachment portion 23A. In a fourth step, the support 30 is driven into the second through hole 25X of the first mounting portion 23A, thereby fixing the adjustment portion 20 to the rafter 3. By fixing the adjustment portion 20 to the rafter 3, the eaves end member 10 is fixed.

[0049] The fifth step is a step in which the second mounting portion 23B is fixed to the rafter 3. In the fifth step, the support 30 is driven into the third through hole 24Y and the fourth through hole 25Y of the second mounting portion 23B, thereby fixing the second mounting portion 23B to the rafter 3. In addition to the first mounting portion 23A, the second mounting portion 23B is further attached to the rafter 3, so that the adjustment portion 20 is attached so as to sandwich the rafter 3 in the vertical direction. This allows the eaves member 10 to be stably positioned.

[0050] A first effect of this embodiment will be described. The eaves member 10 of the embodiment includes an adjustment unit 20 that can move in the gradient direction DS when the eaves member 10 is not fixed. Since the adjustment unit 20 moves by sliding on the lower surface 3B of the rafter 3 or the upper surface 4B of the sheathing board 4, the adjustment unit 20 can move smoothly in the gradient direction DS in the second step. Since the adjustment unit 20 slides on the lower surface 3B of the rafter 3 or the upper surface 4B of the sheathing board 4, the position of the main body 11 in the second direction D2 can be adjusted. By attaching the adjustment unit 20 to the sheathing board 4 and the rafter 3, the main body 11 is positioned away from the end surface 3A of the rafter 3, so that the eaves member 10 can be positioned parallel to the horizontal beam 6 regardless of the positions of the end surfaces 3A of the multiple rafters 3.

[0051] A second effect of this embodiment will be described. The adjustment portion 20 includes an attachment portion 23. The attachment portion 23 has a temporary fixing hole 24 and a fixing hole 25. After the main body portion 11 is temporarily fixed by the attachment portion 23 in the third step and the position of the main body portion 11 is finely adjusted, the adjustment portion 20 is fixed to the rafters 3 in the fourth step, so that the eaves end member 10 can be positioned with high precision. Since the position of the main body portion 11 can be finely adjusted in the third step, the eaves end member 10 can be positioned with high precision regardless of the precision with which the eaves end member 10 is positioned in the second step.

[0052] A third function of this embodiment will be described. As shown in FIG. 11, the conventional eaves member 40 includes a wide lattice 41, two gutterings 42, a fascia board 43, and an eaves purlin 44, each of which is an independent member. To construct the conventional eaves member 40, a process of arranging each of the multiple members was required. In the embodiment of the eaves member 10, members having different functions are integrally formed as the main body 11. Furthermore, since the adjustment part 20 is integrally formed with the main body 11, the main body 11 is arranged at the eaves 5 by attaching the adjustment part 20 to the rafter 3. Therefore, the eaves member 10 requires fewer steps to construct the eaves 5 of the roof 2 than the conventional eaves member 40, and can be constructed in a shorter time than the conventional eaves member 40. In addition, since the main body 11 is composed of a single member, errors during construction are less likely to occur than in the conventional eaves member 40 composed of multiple members.

[0053] The effects of this embodiment will be described. (1) The eaves member 10 includes a main body 11 that covers the end 4A of the sheathing board 4 and the end face 3A of the rafter 3, and an adjustment part 20 that adjusts the position of the main body 11. The adjustment part 20 extends from the main body 11 along the slope direction DS of the roof 2 and contacts at least one of the rafter 3 and the sheathing board 4.

[0054] According to this configuration, the position of the main body 11 can be adjusted by the adjustment unit 20, so that the eaves member 10 can be easily arranged in an appropriate position. By adjusting the position of the main body 11 so that the main body 11 is parallel to the horizontal beam 6, the eaves member 10 can be arranged in an appropriate position.

[0055] (2) The adjustment unit 20 includes a first adjustment unit 21 that contacts the upper surface 4B of the sheathing board 4, and a second adjustment unit 22 that contacts the lower surface 3B of the rafter 3. With this configuration, the adjustment unit 20 contacts the upper surface 4B of the sheathing board 4 and the lower surface 3B of the rafter 3, making it easy to move the adjustment unit 20 along the slope direction DS of the roof 2. By moving the adjustment unit 20 along the slope direction DS of the roof 2, the position of the eaves end member 10 can be adjusted so that the eaves end member 10 is perpendicular to the rafter 3.

[0056] (3) The adjustment unit 20 includes an attachment portion 23 that is attached to the rafter 3. The attachment portion 23 has a temporary fixing hole 24. The temporary fixing hole 24 is an elongated hole extending in the gradient direction DS of the roof 2. With this configuration, the eaves member 10 can be attached to at least one of the sheathing board 4 and the rafter 3 by driving the support 30 into the temporary fixing hole 24. Because the temporary fixing hole 24 is an elongated hole extending in the gradient direction DS of the roof 2, the position of the main body portion 11 can be fine-tuned even after the support 30 is driven into the temporary fixing hole 24.

[0057] (4) The mounting portion 23 has fixing holes 25 different from the temporary fixing holes 24. With this configuration, the eaves end member 10 can be attached to at least one of the sheathing board 4 and the rafters 3 by driving the supports 30 into the fixing holes 25. After the supports 30 are driven into the temporary fixing holes 24 to fine-tune the position of the main body portion 11, the supports 30 are driven into the fixing holes 25, thereby preventing the eaves end member 10 from becoming misaligned in the future.

[0058] (5) The fixing hole 25 is a perfect circle. The fixing hole 25 is arranged to be aligned with the temporary fixing hole 24 in the gradient direction DS of the roof 2. According to this configuration, since the fixing hole 25 is a perfect circle, the support 30 driven into the fixing hole 25 can easily suppress the positional deviation of the eaves member 10. In addition, since the fixing hole 25 is aligned with the temporary fixing hole 24 in the gradient direction DS of the roof 2, the support 30 driven into the fixing hole 25 is arranged in the gradient direction DS of the roof 2 with the support 30 driven into the temporary fixing hole 24. Therefore, the support 30 driven into the fixing hole 25 is easily arranged in the same member as the support 30 driven into the temporary fixing hole 24. The member in which the support 30 driven into the temporary fixing hole 24 is arranged is, for example, the rafter 3.

[0059] (6) The main body 11 includes a drainage portion 13 that covers the end surface 4C of the end portion 4A of the sheathing board 4. The drainage portion 13 includes a first drainage portion 13A that faces the end surface 4C of the sheathing board 4, and a second drainage portion 13B that extends downward from the first drainage portion 13A.

[0060] According to this configuration, the drainage 13 covers the end face 4C of the end 4A of the sheathing board 4, so water is less likely to come into contact with the sheathing board 4. This makes it possible to delay deterioration of the sheathing board 4 due to rain, etc. In addition, because the first drainage 13A faces the end face 4C of the sheathing board 4 and the second drainage 13B extends downward from the first drainage 13A, water flowing over the drainage 13 can be easily drained from the roof 2.

[0061] (7) The main body 11 includes a fascia portion 14 that covers the end face 3A of the rafter 3. With this configuration, the fascia portion 14 covers the end face 3A of the rafter 3, thereby protecting the end face 3A of the rafter 3. This makes it possible to slow down deterioration of the rafter 3 due to rain, etc.

[0062] (8) The adjustment portion 20 is integrally formed with the main body portion 11. With this configuration, when the main body portion 11 is formed by aluminum drawing or aluminum extrusion, the adjustment portion 20 can be formed at the same time. In this way, since the main body portion 11 and the adjustment portion 20 are integrally formed, manufacturing efficiency can be improved.

[0063] (9) A building 1 having a roof 2, comprising an eaves member 10 according to any one of (1) to (8). With this configuration, the eaves member 10 can be positioned in an appropriate position by adjusting the position of the main body 11 with the adjustment unit 20, so that the eaves member 10 can be easily constructed.

[0064] (10) A construction method for the eaves 5 of a roof 2, comprising a step of adjusting the position of the main body 11 so as to be disposed parallel to the horizontal beam 6 by moving the adjustment unit 20 along at least one of the sheathing boards 4 and the rafters 3 in the gradient direction DS. According to this configuration, since the position of the main body 11 can be adjusted by the adjustment unit 20, it is easy to position the eaves member 10 so that the main body 11 is parallel to the horizontal beam 6.

[0065] <Modification> The above-mentioned embodiment is an example of a possible form of the construction method of the eaves edge member 10, the building 1, and the eaves edge 5 of the roof 2, and is not intended to limit the form. The construction method of the eaves edge member 10, the building 1, and the eaves edge 5 of the roof 2 may take a form different from the form exemplified in the above-mentioned embodiment. Such an example is a form in which part of the configuration of the embodiment is replaced, changed, or omitted, or a form in which a new configuration is added to the embodiment. Modified examples of the embodiment are shown below.

[0066] (1) With reference to FIG. 7, an eaves edge member 10 according to a first modified example will be described. The fascia plate 14A of the fascia portion 14 does not have to be arranged parallel to the vertical direction.

In the eaves edge member 10 of the fourth modified example, the fascia board portion 14 is arranged to extend in the vertical direction from the first drip edge 13A.

[0070] (5) As long as the adjustment part 20 extends from the main body part 11 along the slope direction DS of the roof 2 and contacts at least one of the rafters 3 and the subfloor boards 4, the length of the adjustment part 20 in the first direction D1 may be shorter than the length of the main body part 11 in the first direction D1.

[0071] (6) Adjustment portion 20 may be configured as a separate body from main body portion 11. The plate-shaped member that is adjustment portion 20 may be attached to wide mai portion 12 and fascia portion 14 of main body portion 11 with bolts and nuts. Alternatively, the plate-shaped member that is adjustment portion 20 may be attached to wide mai portion 12 and fascia portion 14 of main body portion 11 by welding.

[0072] (7) The mounting portion 23 does not have to include the fixing hole 25. In this case, in the fourth step of the construction method for the eaves 5, the support 30 may be driven into the portion of the adjustment portion 20 that overlaps with the rafter 3, and the adjustment portion 20 may be fixed to the rafter 3, thereby fixing the main body portion 11.

[0073] (8) The eaves member 10 may have a plurality of adjustment parts 20 aligned in the first direction D1. The plurality of adjustment parts 20 extend from the main body 11 along the slope direction DS of the roof 2 and contact at least one of the rafters 3 and the sheathing boards 4. The length of the plurality of adjustment parts 20 in the first direction D1 may be shorter than the length of the main body 11 in the first direction D1.

[0074] (9) The temporary fixing holes 24 may include only one of the first through hole 24X and the third through hole 24Y. In this case, the other of the first through hole 24X and the third through hole 24Y that is not included in the temporary fixing holes 24 may be formed separately from the temporary fixing holes 24. The shape of the other of the first through hole 24X and the third through hole 24Y that is formed separately from the temporary fixing holes 24 may be different from the shape of one of the first through hole 24X and the third through hole 24Y that is included in the temporary fixing holes 24. Alternatively, the other of the first through hole 24X and the third through hole 24Y that is not included in the temporary fixing holes 24 may not be provided in the adjustment portion 20.

[0075] (10) The fixing hole 25 may include only one of the second through hole 25X and the fourth through hole 25Y. In this case, the other of the second through hole 25X and the fourth through hole 25Y that is not included in the fixing hole 25 may be formed separately from the fixing hole 25. The shape of the other of the second through hole 25X and the fourth through hole 25Y that is formed separately from the fixing hole 25 may be different from the shape of one of the second through hole 25X and the fourth through hole 25Y that is included in the fixing hole 25. Alternatively, the other of the second through hole 25X and the fourth through hole 25Y that is not included in the fixing hole 25 may not be provided in the adjustment section 20.

[0076] (11) The third step of the construction method may be a step in which the eaves member 10 is temporarily fixed by the second mounting portion 23B. In this case, in the third step, the support 30 is driven into the third through hole 24Y of the second mounting portion 23B, and the movement of the adjustment portion 20 is restricted, thereby temporarily fixing the main body portion 11 to the position arranged in the second step. In the fourth step, the support 30 is driven into the fourth through hole 25Y of the second mounting portion 23B, thereby fixing the adjustment portion 20 to the rafter 3. In the fifth step, the support 30 is driven into the first through hole 24X and the second through hole 25X of the first mounting portion 23A, thereby fixing the first mounting portion 23A to the rafter 3.
