[Conventional technology]

Conventionally, as a panel mounting method when forming a vertical wall of a building using an ALC panel, a reinforcing bar is placed in a groove provided in a vertical joint portion of the panel, and the groove is filled with cement mortar. The method of fixing them to each other was common. As a typical example thereof, as shown in FIG. 7, for example, an upward ruler angle 3 is provided on an upper surface of an upper flange 2 of a beam 1 along the longitudinal direction of the beam 1, and an outer vertical surface thereof is a beam 1.
The upper flange 2 is fixed so as to slightly project outward from the end portion, and the receiving object 5 is fixed horizontally from the ruler angle 3 to the vertical joint portion of the panel 4 in the horizontal direction.
Both ends of the width direction of the joint are placed on the receiving object 5, joint joints 7 are arranged in joint grooves 6 provided on the longitudinal side surfaces of the panel 4, and the lower ends of the joint reinforcing bars 7 are welded to the receiving article 5. The joint groove 6 is filled with cement mortar to fix the lower part of the panel.

In addition, as a method of mounting the upper part of the panel 4, in order to provide a seismic resistant structure, a downward ruler angle 8 is provided on the lower surface of the upper flange 2 of the beam 1 at the vertical joint of the panel 4, and a vertical ruler angle at which the vertical outer surface is upward. 3 is fixed so as to coincide with the outer vertical surface of the joint 3 and is welded to the side surface near the upper end of the joint streak 9 arranged near the upper end of the joint groove 6 and has a notch as shown in FIG. Slide flag hardware 12 consisting of hardware 11 fixed so that the surface is parallel to the joint line 9
The inner surface of the panel 4 is mounted by positioning the inner surface of the panel 4 at a desired surface by loosely fitting the downward ruler angle 8 in the notch 13.

As another method of mounting the upper part of the panel, a method of bolting the central part of each panel in the width direction to a metal or the like protruding from a beam or the like with a washer is used. A specific example is shown in FIG. Show. That is, the upper side of the panel 4 is provided with the same downward-pointing ruler angle 8 as described above, and the curved strip-shaped inner plate 14 is inserted into the panel 4 through the bolt 15
There is also a construction method in which the protruding portion of the downward ruler angle 8 is loosely fitted in the gap formed between the inner plate 14 and the inner surface of the panel 4 by using the lock.

Recently, for example, as shown in No. 61-95807,
A method has been proposed that improves the earthquake resistance without fixing the vertical joints of the panels to each other.
As shown in FIG. 11 and FIG. 11, a hanging piece 18 is provided on the side opposite to the panel surface of the vertical flange 17 of the mounting hardware 16 having an L-shaped cross section, and a gap 19 between the vertical flange 17 and the hanging piece 18 is provided perpendicular to the ruler angle 3. Department
20 is fitted and fixed to the vertical flange 17, and the plate 22 is inserted into the opening 21 of the vertical flange 17 which is opened downward.
The center part of the ALC panel 4 is placed on top, and the vertical joint part of the ALC panel is a receiving plate 24 suspended on the ruler angle 3.
To maintain a gap with the ruler angle 3 and to secure the upper and lower parts of the panel to the mounting hardware 16 or the plate 22 with mounting bolts 25 protruding from the panel surface. The vertical joint of the ALC panel is mortar or the like. There is also a construction method that allows adjacent panels to slide slightly vertically without fixing with.

[Problems to be solved by the invention]

However, in the method of arranging the reinforcing bars in the joint groove 6 among the above-mentioned mounting methods, since the joint reinforcing bars 7 and 9 are not intertwined with the reinforcing reinforcing bar arranged in the panel 4, the joint reinforcing bars 7 and 9 are not entangled. The panel mounting strength due to is due to the shear strength of ALC only, and there is a drawback that when a large load is applied in the direction of the outer surface of the panel 4, the joint portion on the inner surface of the panel 4 cracks.

Moreover, in the method of bolting each panel 4,
The surface of the bolt 15 is made flat by using a repair material so that the end surface of the bolt 15 cannot be seen.However, repair marks are visible on the outer surface, and cracks are easily generated at this part, and rainwater etc. may enter. There's a problem.

Also, in the mounting method disclosed in Japanese Utility Model Publication No. 61-95807, the mounting hardware is
When 16 is fixed to the ruler angle 3, the welding length is likely to be insufficient, and the welding becomes a stand-up welding, so that it requires skill in the work, and the number of parts used increases and the cost increases. There are drawbacks such as the need for accurate positional accuracy of the embedded metal parts on the upper and lower parts of the panel.

SUMMARY OF THE INVENTION It is an object of the present invention to eliminate such drawbacks, provide a panel mounting method that is extremely simple to construct, has excellent earthquake resistance, and is inexpensive.
