2. Description of the Related Art Conventionally, there are various types of vertical wall structures in which an outer wall panel such as an ALC panel is attached to a building frame to constitute a vertical wall. There is a so-called locking structure in which a panel is mounted so as to be able to swing slightly along the wall surface with the center of the lower end face as a fulcrum.

FIG. 6 is a partially cutaway perspective view showing an example of a conventional vertical wall panel mounting structure. FIG. 7 shows VII-V of FIG.
FIG. FIG. 8 is an arrow view showing a mounting structure of a vertical wall panel using an anchor different from that of FIG. 7. FIG. 4 is a perspective view of an example of the inazuma type fitting. FIG.
It is a perspective view of an example of a self-weight receiving bracket.

In the locking structure, for example, as shown in FIG. 6, a vertical portion of a self-weight receiving member 17 having a T-shaped cross section is provided on the upper end of the lower surface of the lower vertical wall panel 1 on its center line. Is screwed with a bolt 14 to a tubular anchor 15 buried in the width direction of the vertical wall panel 1 from the long side of the small side. Further, the vertical portion of the weight receiving bracket 17 is fixed to the outdoor side of the vertical portion 6a of the ruler angle 6 fixed to the upper surface 5a of the beam 5 of the skeleton at a desired width.

[0005] At the lower end of the rear surface of the upper vertical wall panel 11, as shown in FIG. The snap fastener 13 is provided with ribs 13a on both sides in the longitudinal direction, and one half (upper side) divided into two stages is formed with a long hole 13b on its center line. And Inazuma-type fitting 1
As shown in FIG. 6, the upper half of 3 is screwed with a bolt 14 to a tubular anchor 15 buried in the width direction from the long edge of the upper vertical wall panel 11. Then, the lower end face of the upper vertical wall panel 11 is supported on the horizontal portion 17a of the own weight receiving bracket 17 screwed to the lower vertical wall panel 1 described above, and the other end of the above-mentioned inner type metal fitting 13 is supported.

In addition, since the anchor fittings 15 are embedded in the vertical wall panels 1 and 11, the appearance is excellent, and the construction can be performed in a dry manner, so that there is an advantage that the construction period can be shortened.

However, in this structure, for example, the length 150
In the case of embedding the tubular anchor fitting 15 having a width of 3 mm in the width direction of the vertical wall panels 1 and 11 having a width of 600 mm, the depth of the vertical wall panels 1 and 11 is exactly 380 mm in the right angle direction from the long side face. Since it is necessary to drill the above holes, there is a problem that skill is required and time is required. Also, vertical wall panel 1,
When a large negative pressure acts on the surface of the vertical wall panel 11, the mounting brackets 13, 17 that are in contact with the rear surfaces of the vertical wall panels 1, 11
Ends of the vertical wall panels 1 and 11, and strong tension is applied to the mounting bolts 14 via the mounting brackets 13 and 17, so that the mounting strength tends to be insufficient.

With screws. In this method, since an excessive pulling force does not act on the bolt 14, the anchor fitting 4 having a length of 150 mm can be inserted from the short side of the short side, so that the drilling depth may be about 170 mm, and the operation is simplified. And the dimensional accuracy is improved.

However, in this method, the number of parts such as the backing plate 6 is increased, so that the price of the mounting bracket for the vertical wall panel is increased, and the anchor metal 4 is inserted from the upper edge of the vertical wall panels 1 and 11. Then, attach the weight receiving bracket 17 to the bolt 14
