DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] (Embodiment 1) 1. Overview The fixture 6 of this embodiment is provided so as to straddle adjacent building boards in the left-right direction. Here, in the case of an exterior wall, the exterior material 2 is used as the building board. The fixture 6 attaches the exterior material 2, which is the building board, to the wall base 5, which is the base of the building. The fixture 6 includes a fixed plate portion 61 fixed to the wall base 5, a horizontal piece 62 protruding forward from the fixed plate portion 61, and upper and lower support pieces 63 provided on a plane facing the fixed plate portion 61 at the front end of the horizontal piece 62. The upper and lower support pieces 63 are arranged outside the left and right ends of the fixed plate portion 61 and inside the left and right ends of the fixed plate portion 61. The upper and lower support pieces 63 include an upper support piece 631 and a lower support piece 632. The upper support piece 631 protrudes upward from the horizontal piece 62 and engages with the lower end of the upper exterior material 2 among the exterior materials 2 adjacent in the vertical direction. The lower support piece 632 protrudes downward further than the horizontal piece 62, and engages with the upper end of the lower exterior material 2 of the vertically adjacent exterior materials 2. Both the upper support piece 631 and the lower support piece 632 are disposed on a plane facing the fixed plate portion 61 at a position corresponding to the outer side of both the left and right ends of the fixed plate portion 61 and at a position corresponding to the inner side of both the left and right ends of the fixed plate portion 61.

[0011] In a normal fastener such as that in Patent Document 1, the left-right dimension of the portion that engages with the exterior material is smaller (narrower) than the left-right dimension of the portion that is fixed to the wall base. On the other hand, in the fastener 6 of this embodiment, the upper and lower support pieces 63 are positioned outside both the left and right ends of the fixing plate portion 61 and inside both the left and right ends of the fixing plate portion 61, so that the upper and lower support pieces 63 can engage with the exterior material 2 over a wide range in the left-right direction. Therefore, the fastener 6 of this embodiment can improve the mounting strength of the exterior material 2 to the wall base 5.

[0012] In this embodiment, the case where the exterior material 2 is used as the building board is illustrated, but the present invention is not limited to this, and an interior material can be used as the building board.

[0013] 2.Details The fixture 6 of this embodiment can be used in the joint structure 1 as described below. The joint structure 1 includes an exterior material 2, a fixture 6, and a scrap board member 3. The exterior material 2, the fixture 6, and the scrap board member 3 are located in front of the wall base 5. In this embodiment, the front means the direction from the inside of the building to the outside. The rear means the direction from the outside of the building to the inside. The up means the vertically upward direction, and the down means the vertically downward direction. The left direction means the direction perpendicular to the front-rear direction and the up-down direction, and means the direction toward the left when the joint structure 1 is viewed from the front. The right direction means the direction perpendicular to the front-rear direction and the up-down direction, and means the direction toward the right when the joint structure 1 is viewed from the front. In addition, the expressions "upper", "lower", "horizontal", "forward" and the like in the claims do not indicate the state of use, but are described based on the view as shown in FIG. 1 in order to clearly express the positional relationship of each part of the "fixture", and the left-right direction may be used as the up-down direction, and the front-rear direction may be used as the up-down (down-up) direction.

[0014] <Exterior material 2> The exterior material 2 is a member that constitutes the exterior wall of a building. In this embodiment, a ceramic siding material is used as the exterior material 2, but other siding materials such as metal siding materials can also be used. The ceramic siding material is a hardened product of a hydraulic material containing cement, aggregate, reinforcing fiber, water, etc.

[0015] The exterior material 2 is formed in a rectangular plate shape when viewed from the front (when viewed from the front). The exterior material 2 is formed to extend more in the left-right direction than in the up-down direction, and is horizontally long. The exterior wall of the building is formed by arranging a plurality of exterior materials 2 in the up-down direction and the left-right direction. Two exterior materials 2 adjacent in the up-down direction are connected by a tongue and groove joint. In this embodiment, various types of tongue and groove joints can be used, and for example, two exterior materials 2 adjacent in the up-down direction can be connected by a joint (see FIG. 6). In this case, a receiving part 21 is formed at the upper end of the exterior material 2 over the entire length in the left-right direction. Also, a real protrusion 22 is formed at the lower end of the exterior material 2 over the entire length in the left-right direction. Furthermore, a locking part 23 is formed at the lower end of the exterior material 2 over the entire length in the left-right direction. The locking part 23 has a vertical dimension shorter than the vertical dimension of the real protrusion 22, and is formed behind the real protrusion 22. Also, a groove part 24 is formed between the real protrusion 22 and the locking part 23 over the entire length in the left-right direction.

[0016] The front surface (outdoor side) of the exterior material 2 may be formed as a flat surface, or may have various patterns such as bumps and recesses. The front surface of the exterior material 2 is preferably painted. Furthermore, the rear surface (indoor side) of the exterior material 2 is preferably formed as a flat surface so that the water stop piece 31 described below can easily come into contact with it without any gaps. A water stop member 25 made of a hot melt agent or the like is provided on the front surface of the receiving portion 21 over the entire length in the left-right direction.

[0017] <Mounting fixture 6> 1A and 1B show a mounting fixture 6 of this embodiment. The mounting fixture 6 is used to mount multiple exterior materials 2 to a wall substrate 5 of a building. The mounting fixture 6 may be made of metal or non-metal, but if it is made of metal, the mounting fixture 6 can be obtained by processing a metal plate such as a stainless steel plate by appropriately cutting and bending it. The mounting fixture 6 includes a fixing plate portion 61, a horizontal piece 62, and upper and lower support pieces 63.

[0018] The fixing plate portion 61 has a substantially rectangular shape in a front view, and is fixed to the wall base 5 of the building. The fixing plate portion 61 has fixing holes 611, 612. The fixing hole 611 penetrates the fixing plate portion 61 in the front-rear direction. The fixing hole 611 is provided at substantially the center of the fixing plate portion 61 in the left-right direction. The fixing hole 611 is provided above the horizontal piece 62. The fixing hole 612 penetrates the fixing plate portion 61 in the front-rear direction. The fixing hole 612 is located above the fixing hole 611, and multiple fixing holes 612 are provided lined up in the left-right direction at the top of the fixing plate portion 61. Fixing tools such as nails and screws can be inserted into the fixing holes 611, 612.

[0019] The fixing plate 61 is provided with a plurality of ribs 613. One of the plurality of ribs 613 is formed to extend in the left-right direction above the fixing hole 611. One of the plurality of ribs 613 is formed to extend in the up-down direction on both the left and right sides of the fixing hole 611. The rib 613 protrudes from the front surface of the fixing plate 61 to increase the strength of the fixing plate 61.

[0020] The horizontal piece 62 is formed to protrude forward from the fixed plate portion 61. The horizontal piece 62 protrudes forward from the lower end of the fixed plate portion 61. The horizontal piece 62 is formed in a generally plate shape extending in the left-right direction. The horizontal piece 62 is disposed inside the left and right ends of the fixed plate portion 61. In other words, the left-right dimension of the horizontal piece 62 is shorter than the left-right dimension of the fixed plate portion 61. Therefore, the left and right ends of the horizontal piece 62 do not protrude outside the left and right ends of the fixed plate portion 61.

[0021] A horizontal protrusion 66 is formed in the center of the horizontal piece 62 in the left-right direction. The horizontal protrusion 66 protrudes above the upper surface of the horizontal piece 62, and its upper portion is substantially flat. The horizontal protrusion 66 functions as a rib and increases the strength of the horizontal piece 62. As shown in FIG. 1A, a U-shaped slit is formed in the horizontal protrusion 66, and a receiving piece 67 is formed inside this slit. The receiving piece 67 is slightly inclined so that its tip faces forward and protrudes from the upper surface of the horizontal protrusion 66.

[0022] The upper and lower support pieces 63 are provided at the front end of the horizontal piece 62. The upper and lower support pieces 63 are provided on a plane (on a virtual substantially vertical plane) facing the fixed plate portion 61. In this embodiment, two upper and lower support pieces 63 are provided. The two upper and lower support pieces 63 are lined up in the left-right direction. The left upper and lower support piece 63 has a shorter left-right dimension than the right upper and lower support piece 63.

[0023] The upper and lower support pieces 63 are disposed outside both left and right ends of the fixed plate portion 61 and inside both left and right ends of the fixed plate portion 61 .

[0024] Each of the upper and lower support pieces 63 aligned in the left-right direction includes an upper support piece 631 and a lower support piece 632. The upper support piece 631 protrudes upward beyond the horizontal piece 62. The upper support piece 631 is formed continuously over the entire length of each of the upper and lower support pieces 63 in the left-right direction. The lower support piece 632 protrudes downward beyond the horizontal piece 62. Two lower support pieces 632 are provided on each of the upper and lower support pieces 63.

[0025] That is, the left end of the left upper and lower support piece 63 protrudes leftward (outward) than the left end of the fixed plate part 61. The right end of the left upper and lower support piece 63 is located to the right (inner) of the left end of the fixed plate part 61 and slightly leftward of the center in the left-right direction of the fixed plate part 61. The left upper support piece 631 is formed so as to be continuous from one end to the other end in the left-right direction, so that its strength can be increased compared to when it is divided in the left-right direction.

[0026] The left upper and lower support piece 63 has lower support pieces 632 at the left and right ends. The left lower support piece 632 is located to the left (outside) of the left end of the fixed plate part 61. The right lower support piece 632 is located to the right (inside) of the left end of the fixed plate part 61, and is located approximately in the center in the left-right direction of the fixed plate part 61. Since the lower support piece 632 is thus formed at one end and the other end in the left-right direction away from each other, it is possible to easily engage the exterior material 2.

[0027] The right end of the right upper and lower support piece 63 protrudes to the right (outside) further than the right end of the fixed plate part 61. The left end of the right upper and lower support piece 63 is located to the left (inside) further than the right end of the fixed plate part 61, and is located approximately in the center of the fixed plate part 61 in the left-right direction.

[0028] The right-side upper and lower support piece 63 has lower support pieces 632 provided at the left and right ends. The right-side lower support piece 632 is located to the right (outside) of the right end of the fixed plate part 61. The left-side lower support piece 632 is located to the left (inside) of the right end of the fixed plate part 61, and is located approximately in the center in the left-right direction of the fixed plate part 61. Since the lower support piece 632 is thus formed at one end and the other end in the left-right direction away from each other, it is possible to easily engage the exterior material 2.

[0029] In the mounting tool 6, the upper support piece 631 of the upper and lower support pieces 63 is formed so as to continue from one end to the other end in the left-right direction, but it is sufficient that at least one of the upper support piece 631 and the lower support piece 632 of the upper and lower support piece 63 is formed so as to continue from one end to the other end in the left-right direction. Therefore, the lower support piece 632 of the upper and lower support pieces 63 may be formed so as to continue from one end to the other end in the left-right direction.

[0030] The sum of the widths in the left-right direction of the right-side and left-side upper and lower support pieces 63 is preferably greater than 1 and less than 3 times the width of the fixing plate part 61 in the left-right direction, more preferably 1.3 to 2.5 times, and even more preferably 1.5 to 2.2 times. In this way, the sum of the widths in the left-right direction of the right-side and left-side upper and lower support pieces 63 is formed to be greater than 1 time the width of the fixing plate part 61 in the left-right direction, so that the upper support piece 631 and the lower support piece 632 of the upper and lower support pieces 63 engage with the exterior material 2 over a wide range in the left-right direction. This makes it possible to increase the strength with which the mounting tool 6 supports the exterior material 2. In addition, the sum of the widths in the left-right direction of the right-side and left-side upper and lower support pieces 63 is formed to be less than 3 times the width of the fixing plate part 61 in the left-right direction, so that the fixing plate part 61 and the horizontal piece 62 can fully support the force applied to the right-side and left-side upper and lower support pieces 63 and the left-side upper and lower support pieces 63. This makes it possible to prevent the fixed plate portion 61 and the horizontal piece 62 from being deformed due to forces applied to the right-side and left-side upper and lower support pieces 63, and to prevent the upper and lower support pieces 63 themselves from being deformed.

[0031] In addition, a regulating piece 64 is formed at the left end of the right upper and lower support piece 63. The regulating piece 64 is located forward (outdoor side) of the fixed plate portion 61. Specifically, the regulating piece 64 is formed by bending vertically forward from the left end of the right upper support piece 631. The regulating piece 64 is formed in a flat plate shape perpendicular to the left-right direction. The regulating piece 64 is disposed in the joint portion 4 consisting of a gap formed between the exterior materials 2 adjacent in the left-right direction in the installed state. In addition, the vertical dimension of the regulating piece 64 is the same as the vertical dimension of the upper support piece 631. The gap between the right upper and lower support piece 63 and the left upper and lower support piece 63 is generated by cutting and forming the regulating piece 64.

[0032] As shown in FIG. 2A and FIG. 2B, each upper support piece 631 is provided with a packing material 7. The packing material 7 is formed to be elastically deformable, and can be formed of a material such as EPDM rubber foam. The packing material 7 is provided so as to be continuous from the front surface (outdoor side) to the rear surface (indoor side) of the upper support piece 631 of each upper and lower support piece 63. In this case, the packing material 7 can be attached to the upper support piece 631 with double-sided tape or the like. By providing the packing material 7 to each of the left and right upper and lower support pieces 63, the packing material 7 is disposed on both the left and right sides of the regulating piece 64. That is, the regulating piece 64 is located between the two packing materials 7. The packing material 7 is also located above the inner lower support piece 632 of each upper and lower support piece 63.

[0033] The mounting tool 6 further includes abutment pieces 68. The abutment pieces 68 are provided at both the left and right ends of the mounting tool 6. The two abutment pieces 68 are formed to protrude outward from the left end or the right end of the fixing plate portion 61. The two abutment pieces 68 are also formed to extend downward from the upper end of the fixing plate portion 61. The lower ends of the two abutment pieces 68 are located below the horizontal piece 62, and the lower ends of the two abutment pieces 68 are connected by a connecting portion 69. An opening 71 is formed between the fixing plate portion 61 and the connecting portion 69. The abutment pieces 68 are provided at both the left and right ends of the mounting tool 6, thereby improving the strength of the fixing plate portion 61. The abutment pieces 68 also form a gap between the fixing plate portion 61 and the exterior material 2. For this reason, the heads of fasteners such as nails and screws for fixing the fixing plate portion 61 fit into the gaps formed by the abutment pieces 68, and therefore can be prevented from coming into contact with the exterior material 2 and interfering with the exterior material 2. Furthermore, by increasing the dimension of the abutment piece 68 that protrudes from the fixed plate portion 61 side to the outdoor side, a sufficient ventilation space can be formed between the wall base 5 and the exterior material 2.

[0034] <Scrapboard material 3> The waste board member 3 is used to ensure the watertightness of the joint structure 1. The waste board member 3 is a member extending in the vertical direction, and is formed with water stop pieces 31 on the left and right. Specifically, the waste board member 3 includes a flat board-shaped base portion 30 and water stop pieces 31 protruding forward from both the left and right ends of the base portion 30. The two water stop pieces 31 are formed over the entire length of the base portion 30 in the vertical direction. The two water stop pieces 31 are also arranged opposite each other in the horizontal direction. The base portion 30 is formed of resin, rubber, metal, or the like. The water stop piece 31 is formed of an elastic body (a material that can be elastically deformed) such as rubber or soft resin so that it can contact (preferably adhere to) the indoor side surface of the exterior material 2 in the installed state. In addition, the water stop piece 31 is not limited to a case where the entire water stop piece 31 is formed of an elastic body, and only the part that contacts the indoor side surface of the exterior material 2 may be formed of an elastic body. Further, the water stop piece 31 is formed on each of the left and right ends of the base plate portion 30, but is not limited thereto, and multiple pieces may be formed on each of the left and right ends of the base plate portion 30. This further blocks the movement of water in the left and right directions that has entered through the joint portion 4 by the water stop piece 31, improving waterproofing.

[0035] <Joint structure 1> The joint structure 1 using the fixture 6 of this embodiment has the following structure.

[0036] The scrap board member 3 is attached to a wall base 5. Examples of the wall base 5 include pillars, partitions, vertical furring strips, and horizontal furring strips of a building. When attaching the scrap board member 3 to the wall base 5, the rear surface (indoor side) of the base portion 30 can be attached to the front surface (outdoor side) of the wall base 5 with double-sided tape or the like.

[0037] The fixture 6 is disposed on the front surface of the base plate portion 30 of the scrap board member 3. In this case, the dimension in the left-right direction of the fixed plate portion 61 of the fixture 6 is smaller than the distance between the two water stop pieces 31 arranged in the left-right direction. The distance between the abutment pieces 68 provided at both the left and right ends of the fixture 6 is smaller than the distance between the two water stop pieces 31 arranged in the left-right direction. Therefore, the fixture 6 can be disposed without interfering with the left and right water stop pieces 31, and the fixed plate portion 61 of the fixture 6 and the two abutment pieces 68 are disposed between the two water stop pieces 31. Then, with the rear surface of the fixed plate portion 61 of the fixture 6 in contact with the front surface of the base plate portion 30, a fastener such as a nail or a screw is inserted into the fixing holes 611, 612 and driven into the wall base 5, thereby fixing the fixed plate portion 61 to the wall base 5, and the fixture 6 can be attached by fixing the fixed plate portion 61 to the wall base 5 via the scrap board member 3.

[0038] The exterior material 2 is attached to the wall base 5 by the mounting fixture 6. In this case, the upper end of the exterior material 2 is hooked onto the lower support piece 632 of the mounting fixture 6 at the receiving part 21, as shown in Figures 4, 5, and 6. That is, the lower support piece 632 is disposed in front of the receiving part 21, and the abutment piece 68 comes into contact with the rear surface (indoor side) of the exterior material 2, so that the upper end of the exterior material 2 is hooked onto and held by the mounting fixture 6.

[0039] 5 and 6, the upper support piece 631 of the mounting fixture 6 is inserted into the groove 24 of the exterior material 2, and the lower end of the exterior material 2 is hooked to the locking portion 23. That is, the upper support piece 631 is arranged in front of the locking portion 23, and the abutment piece 68 comes into contact with the rear surface (indoor side) of the exterior material 2, so that the lower end of the exterior material 2 is hooked and held by the mounting fixture 6. The packing material 7 provided on the upper support piece 631 is arranged from the outdoor surface of the upper support piece 631 to the outdoor surface of the fixing plate portion 61. That is, the packing material 7 is arranged not only in the groove portion 24, but also between the upper surface of the horizontal piece 62 and the lower surface of the locking portion 23 from the outdoor surface of the upper support piece 631 to the outdoor surface of the fixing plate portion 61. At this time, the packing material 7 is in close contact with the inner surface of the groove portion 24 (the rear surface of the actual protrusion 22 and the front surface of the locking portion 23) and between the horizontal piece 62 and the locking portion 23. This breaks the left-right continuity on the receiving portion 21, making it difficult for rainwater to move laterally on the receiving portion 21 of the lower exterior material 2, i.e., so-called lateral running of rainwater.

[0040] The packing material 7 is provided on the left and right sides of the horizontal piece 62 so as to sandwich the left-right center of the horizontal piece 62. The left-right position of the packing material 7 may be provided at a position corresponding to the position where the lower support piece 632 is provided, as shown in Fig. 2. In this case, the packing material 7 can block the lateral flow of rainwater over a wide range in both directions. The packing material 7 may also be provided at a position corresponding to a position where the lower support piece 632 is not provided, as shown in Fig. 9.

[0041] In this way, of the exterior materials 2 adjacent in the vertical direction, the lower end of the upper exterior material 2 engages with the upper support piece 631, the upper end of the lower exterior material 2 engages with the lower support piece 632, and further, by arranging the actual protrusion 22 of the upper exterior material 2 in front of the receiving actual part 21 of the lower exterior material 2 and the upper and lower support pieces 63, two exterior materials 2 adjacent in the vertical direction can be actually joined and installed. Here, the upper and lower support pieces 63 are arranged outside both the left and right ends of the fixing plate part 61 and inside both the left and right ends of the fixing plate part 61, so that a wide range in the left and right direction of the exterior material 2 engages with the upper and lower support pieces 63. Therefore, the mounting fixture 6 can support the exterior material 2 and withstand wind pressure even in windy places on the upper floors of a building.

[0042] Also, as shown in FIG. 3, the exterior materials 2 are arranged next to each other in the left-right direction. In this case, the mounting fixture 6 is arranged across two exterior materials 2 adjacent to each other in the left-right direction. That is, one mounting fixture 6 is provided so as to span both of the two exterior materials 2 adjacent to each other in the left-right direction. Therefore, of the two exterior materials 2 adjacent to each other in the left-right direction, the left exterior material 2 is held by the left upper and lower support pieces 63, and the right exterior material 2 is held by the right upper and lower support pieces 63. Also, of the two exterior materials 2 adjacent to each other in the left-right direction, the left end face of the right exterior material 2 and the right end face of the left exterior material 2 are arranged opposite each other. Therefore, a joint portion 4 extending in the up-down direction is formed between the two exterior materials 2 adjacent to each other in the left-right direction. Also, a regulating piece 64 is located in the joint portion 4, and the regulating piece 64 is in contact with or in close proximity to the left end face of the right exterior material 2 and the right end face of the left exterior material 2. Therefore, the exterior material 2 comes into contact with the restricting piece 64 and becomes less likely to move in the left-right direction, and the exterior material 2 becomes less likely to shift in position in the left-right direction.

[0043] As described above, a plurality of exterior materials 2 are arranged and installed in the vertical and horizontal directions to form the exterior wall of a building. At this time, at least in the joints 4, the corners of the four exterior materials 2 are held by one fixture 6. The fixture 6 is disposed between the exterior materials 2 and the waste board member 3, and the fixing plate portion 61 of the fixture 6 is positioned between the two water stop pieces 31 of the waste board member 3. Furthermore, the waste board member 3 is positioned behind the joints 4 (on the indoor side), and the water stop pieces 31 of the waste board member 3 come into contact with the rear surface of the exterior material 2 (on the indoor side) without being interfered with by the fixture 6.

[0044] The joint structure 1 thus formed has excellent waterproofing properties even without providing a sealant in the joint 4. In other words, if no sealant is provided in the joint 4, rainwater will penetrate the joint 4 from the front (outdoor side) and reach the rear surface of the mounting fixture 6 and the exterior material 2 through the joint 4. However, when the rainwater reaches the rear surface of the mounting fixture 6 and the exterior material 2 and tries to flow in the left-right direction, it hits the water stop piece 31 and is blocked, making it difficult to flow further outward (further to the right of the right water stop piece 31, or further to the left of the left water stop piece 31). Then, the rainwater flows downward along the base plate 30 and the water stop piece 31 and is drained. Therefore, the rainwater is less likely to penetrate indoors than the scrap board member 3, improving the waterproofing properties of the exterior wall.

[0045] 3. Variations The first embodiment is merely one of various embodiments of the present disclosure. The first embodiment can be modified in various ways depending on the design and the like as long as the object of the present disclosure can be achieved.

[0046] The mounting fixture 6 in the first embodiment is attached to the exterior material 2 for use, but is not limited thereto, and the mounting fixture 6 may also be used for interior materials. For example, it may be used for the interior of an atrium in a large facility or the inner layer of an indoor swimming pool.

[0047] The mounting fixture 6 in the first embodiment includes two upper and lower support pieces 63 aligned in the left-right direction, but is not limited to this and may include one upper and lower support piece 63. In this case, the inner ends of the two upper and lower support pieces 63 in the first embodiment are connected to each other.

[0048] Although the mounting fixture 6 in the first embodiment is composed of one member, it may be composed of two or more members. For example, the mounting fixture may be composed of two members in the left-right direction. In this case, the right mounting fixture has a right upper and lower support piece 63, and the left mounting fixture has a left upper and lower support piece 63.

[0049] Alternatively, the mounting fixture 601 may be as shown in FIG. 7A, FIG. 7B, and FIG. 8. The right and left halves of the mounting fixture 601 are formed approximately symmetrically with respect to the abutting piece 68. The mounting fixture 601 has four upper and lower support pieces 63 arranged in the left-right direction. The two upper and lower support pieces 63 in the right half of the mounting fixture 601 are formed approximately symmetrically with respect to the abutting piece 68, and the two upper and lower support pieces 63 in the left half of the mounting fixture 601 are formed approximately symmetrically with respect to the abutting piece 68. The upper and lower support pieces 63 located outside the left and right ends of the fixing plate part 61 are formed to be supported by the support parts 72 located outside the abutting piece 68. In this case, the upper and lower support pieces 63 located outside the left and right ends of the fixing plate part 61 are strongly supported by the support parts 72, improving the mounting strength of the exterior material 2. In addition, the horizontal pieces 62 and the support parts 72 on the right and left ends of the mounting fixture 601 each have a recessed space 721 from the indoor side toward the outdoor side without being partially formed. As a result, even when a waste board member 3 is used, as shown in FIG. 8, the two water stop pieces 31 of the waste board member 3 can enter the space 721. As a result, the water stop pieces 31 of the waste board member 3 can be installed without being interfered with by the mounting fixture 601. In addition, a part of the upper support piece 631 of the upper and lower support pieces 63 located inside the right end of the fixing plate part 61, which is located near the center of the fixing plate part 61, is formed short in the upward direction so as not to interfere with the fixing hole 611 in a front view. As a result, the upper support piece 631 is less likely to block the fixing hole 611, making it easier to insert a fixing tool such as a nail or a screw into the fixing hole 611. In addition, a restricting piece 64 is formed on the left end of the upper support piece 631 of the upper and lower support pieces 63 located inside the right end of the fixing plate part 61. The restricting piece 64 is located forward (outdoor side) of the fixed plate portion 61 and forward (outdoor side) of the horizontal piece 62. Specifically, the restricting piece 64 is formed by bending vertically forward from the left end of the upper support piece 631 on the right side. Also, the left end side of the upper support piece 631 of the upper and lower support pieces 63 located inside the right end of the fixed plate portion 61 is located near the center of the fixed plate portion 61 and is formed short in part in the upward direction. In other words, since the restricting piece 64 is formed short in the vertical direction, it can be made less noticeable when it is located between the joints of the exterior materials.

[0050] (summary) As described above, the mounting tool 6 according to the first embodiment mounts a building board (exterior material 2) to a foundation (wall foundation 5) of a building. The mounting tool 6 includes a fixed plate portion 61 fixed to the foundation (wall foundation 5) of the building, a horizontal piece 62 protruding forward from the fixed plate portion 61, and upper and lower support pieces 63 that include the front end of the horizontal piece 62 and are provided on a plane facing the fixed plate portion 61. The upper and lower support pieces 63 include an upper support piece 631 and a lower support piece 632. The upper support piece 631 protrudes upward from the horizontal piece 62 and engages with the lower end of the upper building board (exterior material 2) among the building boards (exterior material 2) adjacent in the vertical direction. The lower support piece 632 protrudes downward from the horizontal piece 62 and engages with the upper end of the lower building board (exterior material 2) among the building boards (exterior material 2) adjacent in the vertical direction. Both the upper support piece 631 and the lower support piece 632 are positioned on the plane facing the fixed plate portion 61 at a position corresponding to the outer side of both left and right ends of the fixed plate portion 61, and at a position corresponding to the inner side of both left and right ends of the fixed plate portion 61.

[0051] According to this embodiment, the upper and lower support pieces 63 can engage with the building board (exterior material 2) over a wide range in the left-right direction, and the mounting fixture 6 can support the building board (exterior material 2) and withstand wind pressure even in windy locations on the upper floors of a building. This improves the mounting strength of the building board (exterior material 2) to the base (wall base 5) of the structure.

[0052] The second aspect is a mounting fixture 6 relating to the first aspect, in which at least one of the upper support piece 631 and the lower support piece 632 provided on the upper and lower support pieces 63 is formed continuously from outside the left and right ends of the fixing plate portion 61 to inside the left and right ends of the fixing plate portion 61.

[0053] According to this embodiment, the upper and lower support pieces 63 have a shape that is continuously long in the left-right direction, so that durability against wind pressure is improved.

[0054] The third aspect is the mounting tool 6 according to the first or second aspect, in which the horizontal piece 62 is disposed inside both the left and right ends of the fixing plate portion 61.

[0055] According to this embodiment, during installation, the horizontal piece 62 does not come into contact with the components arranged on the left and right outside of the fixed plate portion 61 (such as the water-stopping piece 31 of the discard board member 3), and is not pushed down in the left-right direction, thereby preventing the function of the components (in the case of the discard board member 3, the function of draining water) from being impaired.

[0056] The fourth aspect is the mounting tool 6 according to the first or second aspect, which is provided so as to straddle the building boards (exterior materials 2) adjacent in the left-right direction, and further includes a restricting piece 64. The restricting piece 64 is located on the outdoor side of the approximate center of the fixing plate portion 61 in the left-right direction.

[0057] According to this embodiment, the right end or the left end of the exterior materials 2 adjacent in the left-right direction abuts against the restricting piece 64, so that the exterior materials 2 are less likely to shift in position in the left-right direction.

[0058] The fifth aspect is the mounting tool 6 according to the fourth aspect, further comprising an elastically deformable packing material 7. The packing material 7 is provided so as to continue from the outdoor surface of the upper support piece 631 to the outdoor surface of the fixing plate portion, and is disposed on both the left and right sides of the restricting piece 64.

[0059] According to this embodiment, rainwater that has entered from the outdoor side of the joint portion 4 to the indoor side flows left and right through the gaps in the connection portions of the building boards (exterior materials 2) that are adjacent in the vertical direction; this is called the lateral flow of water, which is restricted by the gasket material 7, thereby further improving waterproofing.
