In particular, a projection is provided in the notch so that the support fitting slides with less friction in the notch.

However, since the receiving member is fastened by bolts and fixed to the building frame, there has been a problem that damage to the panel due to an earthquake or the like cannot be prevented.

Alternatively, for example, there is a dry construction method in which a partially cutaway perspective view is shown in FIG. 6 and a longitudinal sectional view is shown in FIG.

In this method, a width of 600 mm and a length of 240 mm
A hole 1b is drilled from the vicinity of the upper end of the long side narrow face of the lightweight cellular concrete panel 1 having a thickness of about 0 to 3000 mm and a thickness of about 100 mm or beyond the center, or not shown,
A hole is drilled from the upper and lower short sides, and an anchor 7 having a pipe shape with a length of about 150 mm and having a screw hole in the center at a right angle is buried.

Further, a hole 1 communicating from the back surface of the lightweight cellular concrete panel 1 to a screw hole of the anchor 7 is provided.

c and a bolt 6 passing through said hole 1a
Then, it is fastened to the screw hole of the anchor 7. At the lower end of the lightweight cellular concrete panel 1, a stepped progress-type metal fitting 5 is fastened to the screw hole of the anchor 7 with a bolt 6 penetrating the long hole on one surface and the hole 1 a. . These bolts 6 have slightly thinner tips, and washers 6a are set under the head in advance.

On the other hand, the horizontal plane 3b of the ruler angle 3 is fixed to a desired position on the upper and lower horizontal beams 2 of the frame.

Then, the lightweight cellular concrete panel 1 is suspended, and the horizontal portion 4 of the weight receiving bracket 4 whose lower end small surface is attached to the lower lightweight cellular concrete panel 1 is attached.
In the state where it is carried on the a, the other surface of the inazuma metal fitting 5 is positioned so as to sandwich the vertical surface 3a of the lower ruler angle 3. Also, the vertical surface of the weight receiver 4 fastened to the upper end portion of the lower lightweight cellular concrete panel 1 is brought into contact with the vertical surface 3 a of the upper ruler angle 3. Then, the lightweight cellular concrete panel 1 and the adjacent lightweight cellular concrete panel 1 are positioned so as to form a vertical wall surface by fitting the real portion 1c of each of the long side small side faces, and The lower end 5b of the mold fitting 5, the upper part of the vertical face 4c of the weight receiving fitting 4, and the corner between the vertical face 4c and the horizontal plane 4a are welded to the ruler angle 3, respectively.

Therefore, when the frame swings in the horizontal direction due to an earthquake or the like, the lightweight cellular concrete panel 1 is locked by using the bolts 6 to which the upper and lower metal fittings are fastened as axes. Damage can be prevented.

Thereafter, the light-weight cellular concrete panels 1 of the same level are sequentially attached adjacent to the lightweight cellular concrete panels 1, and then the upper-level lightweight cellular concrete panels 1 are similarly attached. The joints at the upper and lower ends of the lightweight cellular concrete panel 1 are sandwiched with a refractory joint material 10 such as rock wool when the upper lightweight cellular concrete panel 1 is attached. Thereafter, as shown in FIG. A backup material 8 such as foamed styrene is fitted from the outside, and a sealing material 9 is filled on the outside.

Thereafter, the entire outer wall is painted or a tile is applied to the entire outer wall to finish the outer wall, whereby an outer wall having excellent appearance and earthquake resistance can be formed. However, this mounting structure has a problem in that when the tile (not shown) is attached, if the lightweight cellular concrete panel 1 is largely locked, the surface of the adjacent lightweight cellular concrete panel 1 is easily damaged.

In order to prevent this problem, there is a method of using a special joint material of an elastic body, but there is a problem that it is expensive and troublesome.
