A coil spring 14 that is externally fitted to the bolt 13 is interposed between the presser plate 12 and the fixing portion 11c. When the bolt 13 is loosened, the presser plate 12 is separated from the fixing portion 11c and the plate piece 21 is moved. It is possible to always maintain a gap for sandwiching.

  The shape of the support member 11 is not limited as long as it can perform the function described above, and may be changed according to the shape of the outer wall base material 3. For example, as shown in FIG. 3, when the entrance corner and the exit corner of the building are close and the shape of the outer wall base material 3 is irregular, as shown in FIG. 6 as an example of the shape of the support member 11, A notch may be made at one end of the flat plate, and the plate portions located on both sides of the notch may be bent in different directions to form the support portion 11a and the fixing portion 11c.

  Next, the outer wall mounting structure 5 using the outer wall mounting tool 1 will be described. FIG. 1 is a schematic plan view of a building A in which an outer wall panel 2 is installed. The outer wall mounting structure 5 can be used for the X portion that is the entrance corner of the building A and the Y portion where the entrance corner and the exit corner are close to each other.

  As shown in FIGS. 2 and 3, the outer wall mounting structure 5 is a so-called fastening formed by inclining the small edge surfaces of the intersecting portions of the two outer wall panels 2 and 23 forming the entrance corner toward the indoor side. The outer wall panel 6 and the outer wall base material 3 of the two outer wall panels 2 and 23 are connected and fixed so that the holding plate 12 of the outer wall fixture 1 faces the outer wall joint 6 having a shape. .

  The outer wall panel 2 is a member that is installed on the outer wall base material 3 to form the outer wall surface of the building A. When it is installed in a general entrance corner like the X part, it is formed in a rectangular flat plate shape, but when it is installed in a place where the entrance corner and the exit corner are close like the Y part, the building A The shape of the accessory has corners according to the shape. The outer wall panel 2 is provided with a groove steel 22 that opens in the indoor direction along the side end portion on the indoor side, and a plate piece 21 extending in the side direction of the outer wall panel 2 is fixed to the groove steel 22. Yes. This plate piece 21 protrudes from the small edge surface 2 a on the corner of the outer wall panel 2.

  Moreover, as shown in FIG.2 and FIG.3, the outer wall panel 2 inclines the small edge surface 2a by the side of a corner toward the indoor side. This inclination angle is an angle substantially orthogonal to the fixing portion 11 c when the outer wall fixture 1 is fixed to the outer wall base material 3. In addition, in each figure, although a part of the small edge surface 2a is inclined toward the indoor side, the entire small edge surface 2a may be inclined.

  The outer wall base material 3 is a member extending in the vertical direction capable of supporting the outer wall panel 2, and is a pillar or a stud that is a casing. The shape of the outer wall base material 3 is not particularly limited as long as the outer wall panel 2 and the outer wall fixture 1 can be supported and fixed. In addition to the grooved steel, C-shaped steel, H-shaped steel, steel pipe, Alternatively, it may be a wooden prism.

  Next, a procedure for installing the end portion on the corner side of the outer wall panel 2 on the outer wall base material 3 using the outer wall fixture 1 will be described with a focus on the portion X in FIG. As shown in FIG. 2, a plurality of outer wall base materials 3 for installing the outer wall panel 2 are arranged in the portion X in a dense state. First, as shown in FIG. 7, the support member 11 a is fixed to the outer wall base material 3 so that the contact portion 11 b is located on the outdoor side and the fixing portion 11 c is located on the entering corner side. The outer wall fixture 1 is fixed to the outer wall base material 3 by inserting a fixing bolt 13b installed in the outer wall base material 3 into the through hole 11d of the support portion 11a and tightening and fixing with a nut 13c from the opposite side. At this time, both the fixing portion 11c and the holding plate 12 fixed to the fixing portion 11c are inclined in the outdoor direction, and the holding plate 12 is slid in the direction away from the plate piece 21 to the fixing portion 11c. It is fixed.

  Then, the outer wall panel 2 is arrange | positioned in the predetermined position from the outdoor side, and the board piece 21 is made to contact | abut to the contact part 11b. At this time, the fixing portion 11 c protrudes in the horizontal direction from the tip of the plate piece 21, and the holding plate 12 is fixed at a position away from the plate piece 21, so that the holding plate 12 does not interfere with the plate piece 21. The outer wall panel 2 can be easily arranged.

  Next, as shown in FIG. 8, the tool 4 such as a hexagon wrench is inserted into the hole 13 a of the bolt 13 from the outdoor side, and the bolt 13 is rotated in the loosening direction to slide the presser plate 12 in the direction close to the plate piece 21. Let Then, as shown in FIG. 9, the presser plate 12 is moved in the direction of the plate piece 21 until the shaft of the bolt 13 comes into contact with the longitudinal edge of the second insertion hole 12 a, and the bolt 13 is rotated again in the tightening direction. Thus, the presser plate 12 is fixed, and the plate piece 21 is pressed against the contact portion 11b. At this time, since the inclination angle of the small-mouthed surface 2a of the outer wall panel 2 is substantially orthogonal to the fixed portion 11c, the outer wall fixture 1 can be easily operated using the tool 4.

  Further, as described above, the bending angle θ2 of the presser plate 12 is smaller than the inclination angle θ1 of the fixing portion 11c. Therefore, when the presser plate 12 is slid and tightened to the plate piece side, The opposite edge is close to the tip of the fixing portion 11c. Therefore, the plate piece 21 can be reliably sandwiched and fixed between the presser plate 12 and the fixing portion 11c.

  After forming the outer wall mounting structure 5 in this way, as shown in FIG. 2, the other outer wall panel 23 that forms the corner is installed using a dedicated metal fitting. In addition, the other outer wall panel 23 is also formed so that a small face on the corner side is inclined toward the indoor side in the same manner as the outer wall panel 2, and is a so-called vertical joint between the outer wall panel 2 and the outer wall panel 2. A certain outer wall joint 6 is formed. Then, a sealing backup material 7a is packed into the outer wall joint 6, and the sealing 7 is driven to complete the corner. Here, the outer wall panel 2 is installed first, but there is no problem if the other outer wall panel 23 is installed first.

  When the outer wall panel 2 is removed, the above-described procedure may be performed in the reverse order. The sealing 7 and the sealing backup material 7a are removed, the tool 4 is inserted from the outer wall joint 6, and the outer wall mounting tool 1 is operated. Can be removed. Thus, since the outer wall fixture 1 fixes only the side end part of one outer wall panel 2 arrange | positioned in a corner, when only one outer wall panel 2 needs to be replaced | exchanged, it can remove | desorb easily. Maintenance performance can be improved.

  Further, since the fixing portion 11c and the presser plate 12 fixed to the fixing portion 11c are inclined in the outdoor direction, even if a plurality of outer wall base materials 3 are concentrated like the X portion and the Y portion in FIG. The outer wall panel 2 can be reliably fixed using a small space without interfering with the fixture 1. Further, since the presser plate 12 slides in the horizontal direction and comes into contact with the plate piece 21, the presser plate 12 is used even in a narrow space where a sufficient separation distance between the outer wall base material 3 and the outer wall panel 2 cannot be secured. Interference with the piece 21 can be prevented.

  And since the support member 11 and the presser plate 12 are always fixed integrally by the bolt 13, it is not necessary to combine the two members again at the construction site, and it is possible to prevent one of the metal fittings from being lost. Can be improved. Furthermore, since the presser plate 12 has a simple symmetrical shape and the same shape can be used regardless of the shape of the outer wall base material 3, it is only necessary to prevent erroneous attachment to the support member 11 having various shapes. The cost at the time of manufacture can also be held down.

  Needless to say, the embodiment of the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the scope of the idea of the present invention.

  This invention can be used suitably when installing the outer wall material arrange | positioned in the corner of a building.
