  FIG. 1 shows an embodiment. In the construction structure of the exterior material, the exterior wall material 1 is used as the exterior material 111, and includes the exterior wall material 1, a joint material 4, a fastener (locking tool) 6, a longitudinal support (longitudinal member) 520, and the like. Has been.

  The outer wall material 1 is a so-called siding material, and can be exemplified by a ceramic siding material that is a cured product of a molding material containing cement. The outer wall material 1 may be a metal siding material or a resin siding material. The surface of the outer wall material 1 is provided with uneven patterns such as brick tone, wood tone, stone tone, and makeup by printing or painting. As shown in FIG. 2, the outer wall material 1 is formed in a rectangular flat plate shape, for example. A receiving portion 11 is provided at the upper end of the outer wall material 1. The thickness of the receiving part 11 is formed thinner than the thickness of the center part of the outer wall material 1. The receiving portion 11 is formed so as to be biased toward the back side in the thickness direction of the outer wall material 1. The receiving portion 11 is provided over the entire length of the outer wall material 1 in the lateral direction. An overlapping portion 15 is formed at the lower end of the outer wall material 1. The thickness of the overlapping portion 15 is formed thinner than the thickness of the central portion of the outer wall material 1. The overlapping portion 15 is formed so as to be biased toward the surface side in the thickness direction of the outer wall material 1. The overlapping portion 15 is provided over the entire length of the outer wall material 1 in the lateral direction. On the rear side of the overlapping portion 15, a protrusion 13 is provided at the lower end of the outer wall material 1. The lower end surface of the protruding portion 13 is located above the lower end surface of the overlapping portion 15. The protrusion 13 is provided over the entire length in the lateral direction of the outer wall material 1. The end surface 2 of the outer wall material 1 is a side end surface (lateral end surface) of the outer wall material 1. The end surface 2 is formed in a flat surface over the entire length of the outer wall material 1 in the vertical direction.

  The joint material 4 is provided so as to be interposed between the end surfaces 2 of the outer wall materials 1 which are adjacent to each other in the horizontal direction (lateral direction). That is, a joint 3 is formed between the end faces 2 of the outer wall materials 1 which are adjacent to each other in the horizontal direction, and the joint material 4 is provided on the joint 3. The joint material 4 is made of metal, and is formed, for example, by bending a metal plate. The joint material 4 preferably has high corrosion resistance, and is formed of, for example, a Galvalume steel plate (registered trademark), an aluminum material, a fluororesin-based coated steel plate, or the like. The joint material 4 is formed to be long in the longitudinal direction, and the longitudinal dimension of the joint material 4 is preferably equal to the longitudinal dimension of the joint 3 or longer than the longitudinal dimension of the joint 3. The joint 3 is formed over substantially the entire length of one outer wall material 1 in the vertical direction. The thickness (plate thickness) of the joint material 4 is preferably 0.3 to 2 mm, but is not limited thereto.

  As shown in FIG. 3, the joint material 4 includes a blocking portion 40, a support portion 41, and a fixing portion 42. The closing part 40 closes the opening 30 of the joint 3. Accordingly, the width dimension (lateral dimension) of the closing portion 40 is formed to be the same as or slightly larger than the width dimension of the joint 3. In addition, although the width dimension (dimension between the opposing end surfaces 2) of the joint 3 can be 3-15 mm, it is not limited to this. The blocking portion 40 is formed over the entire length of the joint material 4. The support part 41 is provided at the end of the closing part 40 in the lateral direction. The support portion 41 is formed so as to protrude rearward (back side) of the closing portion 40. The support portion 41 is formed over the entire length of the joint material 4. One support portion 41 is provided at each of both end portions of the closing portion 40 in the lateral direction. The two support portions 41 are formed to face each other. The outer surface of each support portion 41 is formed as a contact portion 43. An angle (recess angle) between each support portion 41 and the closing portion 40 is formed as an acute angle. The angles θ1 and θ2 between the support portion 41 and the closing portion 40 are preferably 60 to 85 °. When the angles θ1 and θ2 are less than 60 °, the closing portion 40 is not easily supported by the support portion 41, and the joint material 4 is easily deformed. Moreover, the width of the blocking portion 40 becomes too wide. When the angles θ1 and θ2 are larger than 85 °, the support portion 41 easily comes into contact with the end surface 2 of the outer wall material 1 so that the joint material 4 contacts the end edge 14 (surface side edge 12) of the outer wall material 1. It becomes difficult to make line contact. The angles θ1 and θ2 may be the same or different. The fixing portion 42 is provided at the rear end of the support portion 41 (the end portion not connected to the closing portion 40). One fixing portion 42 is formed on each support portion 41. The fixing portion 42 is formed over the entire length of the joint material 4. The distal end of the fixing portion 42 (the end portion that is not connected to the support portion 41) protrudes outward (sideward) from the closing portion 40. The fixing portion 42 is formed to be parallel to the closing portion 40.

  The fastener 6 is made of a metal such as stainless steel, and is formed long in the horizontal direction.

The upward piece 62 is formed on the attachment piece 69 of the mounting piece 61 so as to protrude obliquely upward and forward. The downward piece 63 is formed to protrude vertically downward on the attachment piece 69 of the mounting piece 61. The upward pieces 62 and the downward pieces 63 are formed alternately in the horizontal direction. The upward piece 62 and the downward piece 63 may be formed by cutting and raising the attachment piece 69. The contact portion 64 is provided at the upper end of the fixed plate 60 so as to protrude forward. The front surface of the contact portion 64 is located in front of the front surface of the fixed plate 60. Further, the front surface of the contact portion 64 is located behind the upward piece 62 and the downward piece 63.

  The fixing hole 66 is provided in the fixing plate 60 at a position corresponding to the downward piece 63. That is, the fixing hole 66 is provided in the fixing plate 60 at a position above the downward piece 63 when the fastener 6 is viewed from the front. In the fastener 6 of FIG. 4A, two fixing holes 66 are provided in the fixing plate 60 side by side at a position above the downward piece 63. Further, the downwardly facing piece 63 and the upwardly facing piece 62 adjacent in the horizontal direction are arranged with a gap 70, and a drain hole 71 is provided at a position corresponding to the gap 70 when the fastener 6 is viewed from the front. Yes. The drain hole 71 is formed by penetrating a boundary portion between the fixed plate 60 and the protruding piece 67. The outer wall material 1 is attached to a wall base 5 with a fastener 6. The wall base 5 is formed with a waterproof wall 51 and a support body 52. The waterproof wall 51 constitutes the outer surface of the building, and is formed by stacking concrete or a large number of bricks, blocks, and stones. The waterproof wall 51 has high waterproof performance and is formed so that rainwater hardly passes from the front surface (outdoor side surface) to the back surface (indoor side surface). The support body 52 is provided on the surface side (outdoor side) of the waterproof wall 51. Therefore, the support body 52 is provided on the outer surface side of the building. The support body 52 includes, for example, a plurality of vertical support bodies 520, a plurality of fixed support bodies 521, and a plurality of horizontal support bodies 522. The vertical support body 520 is formed long in the vertical direction (vertical direction). The lateral support 522 is formed long in the lateral direction (horizontal direction). One end of the fixed support 521 is provided so as to protrude from the back surface of the horizontal support 522. The other end of the fixed support body 521 is fixed to the waterproof wall 51, whereby the lateral support body 522 is fixed to the waterproof wall 51. The vertical support 520 is attached to the surface of the horizontal support 522. The waterproof wall 51 is provided with a plurality of vertical supports 520 arranged at substantially equal intervals in the horizontal direction. The horizontal support 522 is provided across a plurality of vertical supports 520. Further, the horizontal support 522 is provided between the waterproof wall 51 and the vertical support 520. The plurality of vertical supports 520 arranged in the horizontal direction are connected by a horizontal support 522, whereby the rigidity of the support 52 can be increased. The vertical support 520, the fixed support 521, and the horizontal support 522 are made of metal such as steel, and examples thereof include a circular tube, a square tube, an L-shaped steel, a C-shaped steel, an H-shaped steel, a T-shaped steel, and a Z-shaped steel. . As shown in FIG. 1, the vertical support 520 may be formed in a substantially hat-shaped cross section.

  As shown in FIG. 5, the joint material 4 is attached to the surface of the vertical support 520. In this case, the fixing portion 42 of the joint material 4 is fixed to the vertical support 520 with a fixing tool such as a screw or a rivet, or is fixed by welding or the like. The joint material 4 is arranged long along the vertical direction of the vertical support 520. The joint material 4 is provided on the vertical support 520 where the side end of the fastener 6 and the side end of the outer wall material 1 are located, and is not provided on the other vertical supports 520. The fastener 6 is attached to the vertical support 520 after the joint material 4 is attached. The long fastener 6 is mounted across a plurality of vertical supports 520. Two fasteners 6 are attached to the vertical support body 520 provided with the joint material 4 side by side so as to sandwich the joint material 4. In this case, the side end portion of the fastener 6 on the joint material 4 side is disposed on the surface of the fixing portion 42. The fastener 6 is attached to the vertical support 520 where the joint material 4 is not provided so that the back surface of the fixing plate 60 is in contact with the surface of the vertical support 520 at the position where the fixing hole 66 is provided.

  The fastener 6 is fixed to the vertical support 520. In this case, a fixing tool 77 such as a screw or a rivet is screwed or driven into the vertical support 520 through the fixing hole 66. When the fastener 6 is viewed from the front, two fixing holes 66 are provided side by side in the horizontal direction at a position above one downward piece 63. The two fixing holes 66 are provided in the horizontal direction within a range that can be accommodated in the vertical support body 520 located behind (the waterproof wall 51 side). In other words, the interval between the two fixing holes 66 arranged in the horizontal direction is smaller than the width dimension of the vertical support 520 located behind the fixing holes 66. Therefore, the fastener 6 is fixed to the single vertical support 520 by the two fixing holes 66. One fastener 6 is provided across a plurality of (for example, 4 to 10) vertical supports 520 arranged in the horizontal direction. A plurality of fasteners 6 are also mounted side by side in the vertical direction. The interval between the fasteners 6 arranged in the vertical direction is substantially the same as the height of the outer wall material 1.

  Then, as shown in FIGS. 5 and 6, a plurality of outer wall materials 1 are fastened to the vertical support body 520 by the fastener 6, thereby forming an outer wall. In this case, the receiving wall 11 of the outer wall material 1 arranged on the lower side of the fastener 6 is locked (hooked) to the downward piece 63 of the fastener 6. Further, the protrusion 13 of the outer wall material 1 arranged on the upper side of the fastener 6 is placed on the placement piece 61 of the fastener 6, and the protrusion 13 is locked to the upward piece 62 of the fastener 6 (hanging). ). Further, the overlapping portion 15 of the upper outer wall material 1 is disposed on the front surface side (front surface side) of the receiving portion 11 of the lower outer wall material 1. Further, the lower back surface of the outer wall material 1 comes into contact with the front surface of the contact portion 64 of the fastener 6. In this way, the plurality of outer wall materials 1 are attached side by side in the vertical direction.

  When a plurality of outer wall materials 1 are mounted side by side in the horizontal direction, the end surfaces (side end surfaces) 2 of the outer wall materials 1 that are adjacent in the horizontal direction are arranged to face each other. A joint (vertical joint) 3 is formed between the opposing end faces 2. In this joint 3, a closing portion 40 and a support portion 41 of the joint material 4 are arranged. The blocking portion 40 is disposed so as to protrude from the opening 30 of the joint 3 to the outside of the joint 3. The blocking portion 40 protrudes from the joint 3 by about 2 mm. And the outer surface of the support part 41 which is the contact part 43 of the joint material 4 and the edge 14 of the outer wall material 1 are substantially line-contacting. In the thing of FIG. 1, the outer surface (contact part 43) of the support part 41 of the joint material 4 and the surface side edge 12 of the outer wall material 1 (the opening edge part of the joint 3 and the corner part on the surface side of the outer wall material 1) ) And the line contact. Here, “substantially line contact” is not limited to the case where the lines are in contact with each other accurately but may be discontinuous. That is, the substantially line contact refers to a state where the outer surface of the support portion 41 and the edge 14 of the outer wall material 1 are not in contact with each other in a planar shape. The contact portion 43 of the joint material 4 and the surface side edge 12 of the outer wall material 1 are in substantially line contact over the entire length of the joint 3 along the longitudinal direction (vertical direction) of the joint 3. Of the two contact portions 43, one contact portion 43 is substantially in line contact with the surface side edge 12 of one outer wall material 1 of the outer wall materials 1 adjacent in the lateral direction. The other contact portion 43 is in substantially line contact with the surface side edge 12 of the other outer wall material 1 of the outer wall materials 1 adjacent in the lateral direction.

  As described above, the outer wall material 1 is attached to the wall base 5 with the fastener 6, but the outer wall material 1 may be fixed to the vertical support 520 with the fixing tool 72. In this case, screws or nails are used as the fixture 72. Further, a spacer 78 is provided between the vertical support 520 and the back surface of the outer wall material 1 at a place where the fixing tool 72 is provided. The fixture 72 is provided through the outer wall material 1 and the spacer 78 in the thickness direction from the surface of the outer wall material 1 at a position excluding the side end portion of the outer wall material 1. And the outer wall material 1 is fixed to the vertical support body 520 with the fixing tool 72 by making the fixing tool 72 reach | attain and couple | bond with the vertical support body 520 located in the back surface side of the outer wall material 1. FIG. Thus, since the outer wall material 1 is fixed to the vertical support body 520 by the fixing tool 72 in addition to the fastener 6, the mounting strength of the outer wall material 1 is higher than that of the outer wall material 1 attached only by the fastener 6. Will improve. In particular, it is preferable that the outer wall material 1 exposed to a strong wind such as a high-rise building is attached to the vertical support 520 with both the fastener 6 and the fixture 72.

  The construction structure of the outer wall material 1 is preferably changed according to the height of the building. This is because the wind pressure applied to the outer wall material 1 varies depending on the height of the building.

  FIG. 7 shows a construction structure of the outer wall material 1 from the low position to the middle position of the building (between about 15 m from the ground). Since the wind pressure applied to the outer wall material 1 is relatively small from the low position to the middle position of the building, the outer wall material 1 can be attached with a short fastener 8. FIG. 8 shows a short fastener 8. The short fastener 8 has a smaller lateral dimension than the above-described long fastener 6. The fastener 8 is made of metal such as stainless steel, and includes a fixing plate 80, a mounting piece 81, an upward piece 82, a downward piece 83, and a contact portion 84. The fixing plate 80 is formed in a flat plate shape, and is provided with a fixing hole 86 penetrating in the thickness direction. The mounting piece 81 is formed so as to protrude horizontally at the center of the fixing plate 80 in the vertical direction. The upward piece 82 is formed to protrude upward from the tip of the placement piece 81. The upward piece 82 is provided over substantially the entire lateral length of the fastener 8. The downward piece 83 is formed to protrude downward from the tip of the placement piece 81. Two downward pieces 83 are provided side by side in the lateral direction of the fastener 8. The contact portions 84 are provided at both side end portions of the fixed plate 80. The front surface of the contact portion 84 is located in front of the front surface of the fixed plate 80. Further, the front surface of the contact portion 84 is located behind the upward piece 82 and the downward piece 83.

  The fastener 8 is attached to the vertical support 520 after the joint material 4 is attached. When there is the attachment plate 523, the fastener 8 is attached to the vertical support 520 via the attachment plate 523 as shown in FIG. Two fasteners 8 are attached to the vertical support body 520 provided with the joint material 4 side by side so as to sandwich the joint material 4. In this case, the side end portion of the fastener 8 on the joint material 4 side is disposed on the surface of the fixing portion 42. The fastener 8 is attached to the vertical support 520 where the joint material 4 is not provided so that the back surface of the fixing plate 80 contacts the surface of the vertical support 520 at the position where the fixing hole 86 is provided. The fastener 8 is fixed to the vertical support 520. In this case, a fixing tool such as a screw or a rivet is screwed or driven into the vertical support 520 through the fixing hole 86. A plurality of fasteners 8 are attached side by side in the horizontal direction. A plurality of fasteners 6 are also mounted side by side in the vertical direction. The interval between the fasteners 6 arranged in the vertical direction is substantially the same as the height of the outer wall material 1.

  The plurality of outer wall materials 1 are fastened to the vertical support 520 by the fasteners 8 to form an outer wall. In this case, as shown in FIG. 9, the receiving portion 11 of the outer wall material 1 arranged on the lower side of the fastener 8 is locked (hooked) to the downward piece 83 of the fastener 8. Further, the protruding portion 13 of the outer wall material 1 disposed on the upper side of the fastener 8 is placed on the placing piece 81 of the fastener 8, and the protruding portion 13 is locked to the upward piece 82 of the fastener 8 (hanging). ). Further, the overlapping portion 15 of the upper outer wall material 1 is disposed on the front surface side (front surface side) of the receiving portion 11 of the lower outer wall material 1. Further, the lower back surface of the outer wall material 1 comes into contact with the front surface of the contact portion 84 of the fastener 8. In this way, the plurality of outer wall materials 1 are attached side by side in the vertical direction.

  As shown in FIG. 10, when a plurality of outer wall materials 1 are mounted side by side in the horizontal direction, the outer wall materials 1 adjacent in the horizontal direction are arranged so that the end surfaces (side end surfaces) 2 face each other. A joint (vertical joint) 3 is formed between the opposing end faces 2. In this joint 3, a closing portion 40 and a support portion 41 of the joint material 4 are arranged. The blocking portion 40 is disposed so as to protrude from the opening 30 of the joint 3 to the outside of the joint 3. The blocking portion 40 protrudes from the joint 3 by about 2 mm. And the outer surface of the support part 41 which is the contact part 43 of the joint material 4 and the edge 14 of the outer wall material 1 are substantially line-contacting. In the thing of FIG. 10, the outer surface (contact part 43) of the support part 41 of the joint material 4 and the surface side edge 12 of the outer wall material 1 (the opening edge part of the joint 3 and the corner part on the surface side of the outer wall material 1) ) And the line contact. The contact portion 43 of the joint material 4 and the surface side edge 12 of the outer wall material 1 are in substantially line contact over the entire length of the joint 3 along the longitudinal direction (vertical direction) of the joint 3. Of the two contact portions 43, one contact portion 43 is substantially in line contact with the surface side edge 12 of one outer wall material 1 of the outer wall materials 1 adjacent in the lateral direction. The other contact portion 43 is in substantially line contact with the surface side edge 12 of the other outer wall material 1 of the outer wall materials 1 adjacent in the lateral direction.

  FIG. 11 shows a construction structure of the outer wall material 1 from a middle position to a high position (a height of about 13 m or more from the ground). Since the wind pressure applied to the outer wall material 1 is higher than the low position from the middle position to the high position of the building, the outer wall material 1 is fixed by a fixing tool 72 in addition to fixing by a short fastener 8 as shown in FIG. It is preferable. In this case, as shown in FIG. 12, a spacer 78 is provided between the outer wall material 1 and the vertical support 520 at a substantially intermediate position in the vertical direction of the outer wall material 1, and a fixing tool 72 such as a screw is provided on the outer wall material 1. The outer wall material 1 and the spacer 78 are penetrated from the surface to the vertical support body 520 through the thickness direction. A substantially intermediate position in the vertical direction of the outer wall material 1 is supported by a spacer 78 and is fixed to the vertical support 520 by a fixture 72. Thereby, the outer wall material 1 is firmly attached to the vertical support body 520.

  FIG. 13 shows a construction structure of the outer wall material 1 from a middle position to a high position (a height of about 13 m or more from the ground). In this case, as shown in FIG. 11, instead of the outer wall material 1 being fixed by the short fastener 8 and the fixture 72, the outer wall material 1 is fixed by the long fastener 6. FIG. 14 shows a construction structure of the outer wall material 1 by the long fastener 6, and this structure is the same as that of FIG. 6.

  FIG. 15 shows a construction structure of the outer wall material 1 at a high position of the building (a height of about 30 m or more from the ground). Since the wind pressure applied to the outer wall material 1 is higher than that in the middle position at the high position of the building, the outer wall material 1 should be fixed by the fixing tool 72 in addition to fixing by the long fastener 6 as shown in FIG. Is preferred. In this case, as shown in FIG. 12, a spacer 78 is provided between the outer wall material 1 and the vertical support 520 at a substantially intermediate position in the vertical direction of the outer wall material 1, and a fixing tool 72 such as a screw is provided on the outer wall material 1. The outer wall material 1 and the spacer 78 are penetrated from the surface to the vertical support body 520 through the thickness direction. Thereby, the outer wall material 1 is more firmly attached to the vertical support body 520.

  In addition, the construction structure of the outer wall material 1 may be changed depending on the area where the building is constructed in addition to the height of the building. This is because the wind pressure applied to the outer wall material 1 varies depending on the region.

  And the construction structure of the exterior material of this Embodiment as mentioned above has the following characteristics.

  The construction structure of the exterior material according to the present embodiment includes a plurality of vertical supports 520 provided on the outer surface side of the building at substantially equal intervals, a plurality of exterior materials 111 disposed over two or more vertical supports 520, and a horizontal structure. A joint material 4 is provided between the two exterior members 111 adjacent to each other in the direction and provided on the vertical support 520, and a fastener 6 that holds the exterior material 111 on the vertical support 520. The fastener 6 includes an upward piece 62, a downward piece 63, a fixing plate 60, and a fixing hole 66, and is formed to have substantially the same length as the exterior material 111. The lower end of the exterior material 111 is locked to the upward piece 62 of the fastener 6 disposed below the exterior material 111, and the upper end of the exterior material 111 is engaged to the downward piece 63 of the fastener 6 disposed above it. The fixing hole 66 is provided in the fixing plate 60 at a position corresponding to the downward piece 63, and the fastener 6 is fixed to the vertical support 520 through the fixing hole 66.

  Thereby, since the fastener 6 is formed in substantially the same length as the exterior material 111, the exterior material 111 can be hold | maintained over substantially the whole length with the fastener 6. FIG. Therefore, compared with the case where the fastener 6 is much shorter than the exterior material 111, the attachment strength of the exterior material 111 can be improved. Further, since the fixing hole 66 is provided in the fixing plate 60 at a position corresponding to the downward piece 63, the downward piece 63 is obstructed when the fastener 6 is fixed to the vertical support 520 through the fixing hole 66.
