  Using the support member 1, the exterior material 2, the mounting bracket 3, and the draining member 4 as described above, an exterior material mounting structure as shown in FIGS. 1 to 4 can be configured.

  When laying the exterior material 2 on a building as shown in the figure, first, a plurality of support members 1 that are long in the vertical direction are arranged in a horizontal direction on a building frame 11 (in the figure, a shaft assembly composed of columns 11a and a base 11b). Lay down. A waterproof sheet 12 is arranged on the outer surface side of the building housing 11 so that the waterproof sheet 12 is interposed between the building housing 11 and the support member 1. Further, a drainer 16 is provided at the lower end of the support member 1. The drainer 16 is disposed between the support member 1 and the building housing 11 and is fixed to the fixed piece 16a, the extended piece 16b extending obliquely downward from the lower end of the fixed piece 16a, and the extended piece 16b. The lower piece 16c hangs downward from the tip.

  Of the plurality of support members 1, the draining member 4 is disposed on the outer surface of the exterior member 2 where the butting portion in the left-right direction is disposed, and the starter fitting 15 is attached. The starter fitting 15 is disposed on the outer surface side of the draining member 4 at the lower end of the exterior material 2. The starter metal 15 is attached by passing the fixing tool 22 such as a screw through the starter metal 15 and the draining member 4 and driving the fixing tool 22 into the support member 1.

  Next, the exterior material 2 is attached by bringing the exterior material 2 close to the starter metal 15 from above and fitting the upward locking piece 13 of the starter metal 15 into the groove 10 at the lower end of the exterior material 2. A plurality of exterior materials 2 are laid in the lateral direction while abutting the end portions in the lateral direction. At this time, the one exterior part 2 and the other cover part 9 of the adjacent exterior member 2 are engaged with each other so that the exterior members 2 are connected to each other.

  Next, the mounting bracket 3 is approached from above the butt portion of the exterior material 2 laid and the positioning piece 17 of the mounting material 3 is inserted between the butt portions of the exterior materials 2 from the back side of the exterior material 2. The pair of downward locking pieces 14 are fitted into the real part 8 at the upper end of each exterior member 2. Thereby, the mounting bracket 3 is disposed between the draining member 4 and the exterior material 2. The fixed piece of the mounting bracket 3 protrudes upward from the upper end of the exterior material 2.

  At this time, the draining pieces 5 a on both sides of the draining member 4 are respectively arranged on both sides of the mounting bracket 3. Further, when the draining rib 6 is provided, the back surface of the mounting bracket 3 is disposed so as to contact the draining rib 6. Further, the plurality of mounting holes 19 of the mounting bracket 3 are respectively arranged on the outer surface side of each region 21 sandwiched between the draining piece 5 a and the draining rib 6 in the draining member 4, and above the mounting position of each mounting hole 19. The guide rib 7 will be arrange | positioned. Further, the surface of the support portion 20 comes into contact with the back surface of the exterior material 2.

  Next, a fixing tool 22 such as a screw is inserted through the mounting hole 19 provided in the fixing piece 18 of the mounting bracket 3, and the fixing tool 22 is driven into the support member 1. At this time, the fixing tool 22 punches through the draining member 4 and penetrates. Thereby, the mounting bracket 3 and the draining member 4 are fixed to the support member 1, and each exterior member 2 is fixed by the mounting bracket 3.

  The mounting hole 19 used for fixing the mounting bracket 3 may be any one of the plurality of mounting holes 19. Here, if a lateral displacement occurs between the exterior material 2 and the support member 1, the placement position of the attachment hole 19 may be displaced from the position of the support member 1. Since the plurality of mounting holes 19 are provided side by side in the horizontal direction, the mounting holes 19 at positions that coincide with the arrangement positions of the support member 1 can be appropriately selected and used. For example, in the illustrated example, the fixing tool 22 is attached using the attachment hole 19 in the central portion of the fixed piece 18, but a lateral displacement occurs between the exterior material 2 and the support member 1, and the central portion is fixed. When the fixing tool 19 cannot be driven into the support member 8 through the mounting hole 19, the fixing tool 19 can be attached using one of the mounting holes 19 on both sides.

  Next, a plurality of other exterior materials 2 are arranged above the fixed exterior material 2 and the exterior materials 2 are laid in the lateral direction while abutting the end portions in the lateral direction. At this time, one exterior part 2 of the exterior material 2 which adjoins the horizontal direction and the other cover part 9 are unevenly fitted, and this exterior material 2 is connected. Further, the upper and lower exterior materials 2 are connected to each other by the concave and convex fitting between the upper real portion 8 of the lower exterior material 2 and the upper cover portion 9 of the upper exterior material 2.

At this time, the abutting portion of the upper exterior material 2 in the lateral direction is disposed at the position where the mounting bracket 3 is disposed, and the pair of upward locking pieces 13 are fitted in the groove portions 10 at the lower ends of the exterior materials 2 Let Thereby, each exterior member 2 is supported by the mounting bracket 3. Thus, the mounting bracket 3 is fixed at a position where the corners of the four exterior members 2 are abutted. Below the mounting bracket 3, the two exterior members 2 are arranged in a state of being abutted in the lateral direction, and the downward locking pieces 14 are fitted to the real parts 8 of the respective exterior members 2, so that These two exterior materials 2 are fixed. In addition, two exterior members 2 are disposed in a state of being abutted in the lateral direction above the mounting bracket 3 and in a state of being abutted in the vertical direction with the lower exterior member 2. When the upward locking pieces 13 are fitted in the respective groove portions 10, the upper two exterior members 2 are fixed.

  By repeatedly performing such an operation, it is possible to connect and lay a plurality of exterior materials 2 to the support member 1 provided in the building by connecting the four sides.

  As shown in FIG. 3, in the exterior material mounting structure configured as described above, water enters the gap between the laterally adjacent exterior materials 2, and this water travels through the mounting bracket 3 to support member 1. Even toward the side, the progress of the water is blocked by the draining piece 5a after reaching the outer surface of the draining member 4. This water flows down along the outer surface of the draining member 4, and is discharged to the outside through the draining 16 at the lower end of the exterior material 2. For this reason, it is possible to prevent water from reaching the support member 1. In FIG. 3, the traveling direction of water is indicated by arrows. In FIG. 3, the draining rib 6 and the guide rib 7 are not shown.

  Moreover, when the draining rib 6 is provided as described above, the lateral movement of the water on the outer surface of the draining member 4 is further hindered, and this water is more difficult to reach the support member 1.

  Further, when the guide rib 7 is provided as described above, the water flowing down the outer surface of the draining member 4 is guided to both sides of the guide rib 7 by the guide rib 7, and each guide rib 7 is provided. In the region 21, the water flows down mainly on both sides of the region 21. For this reason, even if the fixing tool 22 of the mounting bracket 3 is driven into the region 21, the water flows down on the outer surface of the draining member 4 while avoiding the arrangement position of the fixing tool 22. For this reason, it is prevented that water reaches the arrangement position of the fixing tool 22, and water is prevented from entering the support member 1 side from the penetrating position of the fixing tool 22 in the draining member 4.

  Here, the plurality of mounting holes 19 in the mounting bracket 3 are arranged on the outer surface side of each region 21 of the draining member 4 as described above, and the guide rib 7 is provided in each region 21, so Even if the mounting bracket 3 is fixed to the support member 1 using the holes 19, the guide rib 7 is located above the fixing tool 22, and water enters the support member 1 at the position where the fixing tool 6 is disposed. Is prevented.
