ALC) The present invention relates to an installation method for an ALC vertical wall panel that is easy to install when the panel is used as a vertical wall, has strong attachment parts, and has extremely excellent earthquake resistance.

[Conventional technology]

Conventional-1 The panel installation method when forming the vertical wall of a building using ALC panels is to place reinforcing bars in the grooves provided in the longitudinal joints 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 flange 2 of the beam 1, so that the outer vertical surface of the ruler angle 3 is attached to the upper surface of the upper flange 2 of the beam 1. 2 so that it slightly protrudes outward from the edge of the panel 4, and a bracket 5 is fixed horizontally outward from the ruler angle 3 to the longitudinally tilted part of the panel 4, and both ends of the panel 4 in the width direction are fixed. It is placed on the support 5, and joint lines 7 are provided in the joints 6 provided on the vertical sides of the panel 4, the lower ends of the joint lines 7 are welded to the support 5, and cement mortar is placed in the joint grooves 6. to secure the bottom of the panel.

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 bottom surface of the upper flange 2 of the beam l on the longitudinally tilted part of the panel 4, and a ruler angle 8 pointing upward with its vertical outer surface. A metal fitting 10 having a notch as shown in FIG. 8 is fixed to the side surface near the top end of the joint line 9, which is fixed so as to overlap the outside vertical surface of 3, and is arranged near the top end of the joint line 9. By loosely fitting the downward ruler angle 8 into the notch 13 of the sliding flag metal fitting 12, which is made of the metal fitting 11 fixed so that the surface is parallel to the joint lines 9, the inner surface of the panel 4 can be made into a desired surface. Position and install.

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. show. In other words, a curved strip-shaped lightning bolt +4 with a downward ruler angle 8 similar to the one described above is fixed on the upper side of the panel 4 using a bolt +5 that passes through a hole drilled in the panel 4, and the lightning bolt is fixed. There is also a construction method in which the protrusion of the downward ruler angle 8 is loosely fitted into the gap formed between the inner surface of the panel 4 and the inner surface of the panel 4.

Recently, as shown in Utility Model Application Publication No. 81-95807, a construction method has been proposed that improves seismic resistance by not fixing the vertical hinged portions of panels to each other, and this method is shown in Figure 10. , as shown in Figure H, a hanging piece 18 is provided on the side opposite to the panel surface of the vertical 7 langue 17 of the mold mounting hardware 1B, and the gap 1 between the vertical 7 flange 17 and the hanging piece 18 is
9 is fitted into the vertical part 20 of the ruler angle 3 and fixed, and a 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 longitudinally tilted parts of the A1 and C panels are maintained with a gap from the ruler angle 3 by a support plate 24 suspended from the ruler angle 3, and the upper and lower parts of the panels are secured by mounting bolts 25 protruding from the panel surface. There is also a construction method in which the mounting hardware 16 or the plate 22 is bolted, and the vertically closed portions of the ALC panels are not fixed with mortar, etc., and adjacent panels are allowed to slide slightly vertically.

[The nRHI point that the invention attempts to solve] However,
Among the above-mentioned installation methods, in the method of placing reinforcing bars at the full 6th angle, the joint reinforcing bars 7゜9 do not intertwine with the reinforcing reinforcing bars placed inside the panel 4 at all, so the joint reinforcing bars 7
The mounting strength of the panel according to .

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 15m side of the bolt is not visible on the outside, but the repair marks are visible on the outside, and cracks are likely to occur in this area, and there is a risk of rainwater entering. There's a problem.

In addition, in the installation method of the above-mentioned Japanese Utility Model Application Publication No. G1-95807,
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 was a drawback that the positional accuracy of the embedded metal parts at the top and bottom of the panel needed to be accurate.

The present invention eliminates these drawbacks and is extremely easy to construct.
The purpose of this invention is to provide a method for installing panels that is simple and has extremely excellent earthquake resistance.

[Means for solving problems]

The present invention has been developed as a result of conducting research in order to solve the above-mentioned problems and achieve the above-mentioned purpose, and as a result, the present invention has been achieved.

〔effect〕

According to the installation method of the present invention, the installation work is easy because it is a so-called dry type 1 method that does not use cement mortar etc.
The construction speed is fast, and the fixing of the upper and lower wall panels is possible even if the precision of the position of the embedded metal fittings with screw holes in the panel is inaccurate. It has great flexibility, and in terms of earthquake resistance, it is possible to use fixed metal fittings that protrude from the upper wall panel from the ruler angle as in conventional construction methods, or metal fittings that are fixed and protrude from the upper part of the lower wall panel. Instead of placing it on any hardware, the tip of the bolt screwed into the nut fixed to the bracket that supports the center of the panel in the width direction is placed on the horizontal part 35 of the lower wall panel mounting hardware fixed to the ruler angle to reduce the panel load. Since it is supported virtually at a point, the lower part of the panel can swing around the tip of the pole 41, and both the upper and lower parts of the panel can rotate around the mounting bolts, so the steel frame remains intact even in the event of an earthquake. Even if the structure undergoes interlayer deformation, the panels can easily undergo rocking deformation to follow the deformation, so this is extremely effective.
