[Detailed Description of the Invention] [Industrial Application Field] The present invention is directed to the use of lightweight cellular concrete as a wall material for buildings.
The present invention relates to an installation method for an ALC vertical wall panel that is easy to install when used as a vertical wall, has strong attachment parts, and has excellent earthquake resistance.

[Conventional technology]

Conventionally, the panel installation method when forming the vertical walls of a building using ALC panels is to place reinforcing bars in the grooves provided in the longitudinal dicoin points of the panels, and fill these grooves with cement mortar. The common method was to fix them together. For example, as shown in Fig. 7, a typical example is to place a ruler angle 3 pointing upward along the longitudinal direction of the beam 1 on the upper surface of the upper 7 flange 2 of the beam 1, so that its outer vertical surface is above the beam 1. The flange 2 is fixed so that it slightly protrudes outward from the end, and the bracket 5 is fixed outwardly and horizontally from the ruler angle 3 to the vertical sillage part of the panel 4, and both ends of the panel 4 in the width direction are fixed. is placed on the metal support 5, a joint line 7 is provided in the joint groove 6 provided on the vertical side surface of the panel 4, the lower end of the joint line 7 is welded to the metal support 5, and cement is placed in the joint groove 6. Fix the bottom of the panel by filling it with mortar.

In addition, in order to provide an earthquake-resistant structure, the upper part of the panel 4 is installed by attaching a ruler angle 8 pointing downward to the lower surface of the upper flange 2 of the beam 1 on the longitudinally tilted part of the panel 4, and attaching a ruler angle 8 whose perpendicular outer surface faces upward. A metal fitting IO with a notch as shown in FIG. The inner surface of the panel 4 is positioned at a desired surface by loosely fitting the downward ruler angle 8 into the notch 13 of the slide flag metal fitting 12 made of the metal fitting 11 fixed so that its surface is parallel to the joint line 9. Install it.

Another method for attaching the upper part of the panel is to bolt the center part of each panel in the width direction to a beam or other hardware protruding from the beam using a washer or the like. A specific example of this method is shown in Figure 9. Shown below. That is, a downward ruler angle 8 similar to that described above is provided on the upper side of the panel 4, and a curved band-shaped lightning plate 14 is locked using a bolt 15 that passes through a hole drilled in the panel 4, and the lightning plate 14 and the panel are fixed. Insert a downward ruler angle 8 into the gap created between 4 and the inner surface.
There is also a construction method that loosely fits the protruding part.

Recently, as shown in Utility Model Application No. 61-95807, a construction method has been proposed in which the earthquake resistance is improved by not fixing the vertical joints of the panels to each other. As shown in FIG.
8 is provided, and a gap 19 between the vertical flange 17 and the hanging piece 18 is provided.
is fitted onto the vertical part 20 of the ruler angle 3 and fixed, and the plate 22 is inserted into the downwardly open opening 21 of the vertical flange 17, and the central part of the ALC panel 4 is placed on the horizontal flange 23. The vertical joint part of the ALC panel maintains a gap with the ruler angle 3 by a spacer 24 suspended from the ruler angle 3, and the upper and lower parts of the panel are connected to the mounting hardware 16 or by mounting bolts 25 protruding from the panel surface. Let the plate 22 turn into nuts,
There is also a construction method in which the vertical joint grooves of ALC panels are not fixed with mortar, etc., and adjacent panels are allowed to slide slightly vertically.

[Problem that the invention seeks to solve]

However, in the method of placing reinforcing bars in the joint groove 6 among the above-mentioned installation methods, this joint reinforcing bar 7°9 is
Because it does not intertwine with the reinforced river reinforcing material placed inside,
The installation strength of the panel with these joint reinforcing bars 7 and 9 is ALC
However, if a large load is applied to the outer surface of the panel 4, cracks may occur at the joint portion on the inner surface of the panel 4.

In addition, in the method of bolting each panel 4, the panel 4
A repair material is used to flatten the surface so that the bolts 15 are not visible on the outside, but the repair marks are visible on the outside, and cracks are likely to occur in this area, which may cause rainwater to enter. There is such a thing as Mato.

Moreover, in the installation method of the above-mentioned Utility Model Application Publication No. 61-95807,
When fixing the mounting hardware 16 to the ruler angle 3, the welding length tends to be insufficient, and the welding is performed by rising welding, which requires skill and increases the number of parts used, resulting in high costs. There were drawbacks such as the need for accurate positioning of the embedded metal parts at the top and bottom of the panel.

SUMMARY OF THE INVENTION An object of the present invention is to provide a panel mounting method that eliminates these drawbacks, is extremely easy to construct, has excellent earthquake resistance, and is inexpensive.

[Means for solving problems]

The present inventors have conducted research in order to solve the above-mentioned problems and achieve the above-mentioned object, and as a result, they have arrived at the present invention.

In other words, the construction method of the present invention is to bolt a mounting hardware having a T-shaped longitudinal section to the upper edge of the widthwise center of the lower wall panel so that the vertical part of the T-shape faces toward the outside, and then attach it to the upper edge of the widthwise center of the lower wall panel. The lower part of the upper wall panel is bolted using Inazoma type metal fittings so as to sandwich the ruler angle and the part of the mounting hardware that protrudes in the -L direction. The vertically extending portion of the panel is constructed so as to maintain equal spacing between the panel and the ruler angle by means of a receiving plate attached to the ruler angle.

It is screwed into an embedded metal fitting 32 with a screw hole embedded in the center of the lower part. A receiving plate 37 is attached to the panel longitudinal joint portion of the ruler angle 3, as shown in FIG. This receiving plate 37 can be fixed by bending a steel plate into a U-shaped cross section and hooking it onto the ruler angle 3, as shown in FIG. 6a, for example. It has the same thickness as the mounting hardware 26, and the distance between the lower inner surface of the upper wall panel 27 and the outer surface of the ruler angle 3 is made equal to the distance between the upper inner surface of the lower wall panel 28 and the outer surface of the ruler angle 3. However, if the length of the hem length section 38 is extended below the upper end of the lower wall panel 28, the four corners of the vertical and horizontal corners of the panel will be attached to the receiving plate.
