DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to relates to a structure for mounting lightweight cellular concrete a (ALC) wall panels to structural framework of the building.

[0002]

2. Description of the Related Art Hitherto, as a structure of the type described above, the structure shown in FIG. 3 is most typically known. That is, in the above-mentioned structure, an L-shaped section steel 3 as a kind of structural frame is vertically welded and fixed to both ends of a flange portion 2 of a stud 1 made of an H-section steel of a building. An ALC wall panel 5 is erected on one of the flange portions 4 which is not welded to the stud 1.

[0003] A counterbore hole 6 is formed on the front side of the ALC wall panel 5.
Is drilled at a predetermined depth, and a bolt hole 7 through which a bolt can be passed from the bottom of the counterbore hole 6 toward the back surface of the ALC wall panel 5 is formed. Then, in a state where the base end 10 of the hook bolt 9 having the side surface L-shape can be locked to the flange 4, the tip 8 of the hook bolt 9 is inserted into the bolt hole 7, and the tip 8 When the nut 12 is screwed in after extrapolating the washer 11 to the above, the known mounting structure is obtained.

[0004]

Although the above-mentioned structure has exhibited a corresponding effect, there is room for improvement in the following points. First, if the nut 12 is excessively tightened with respect to the hook bolt 9, the base material of the ALC wall panel 5 is easily broken, and it is difficult to adjust the degree of tightening. In addition, even if the degree of tightening is adjusted, since a latent stress is strongly generated in the vicinity of the hook bolt 9, there is a possibility that the ALC wall panel 5 may be cracked or broken when the building is vibrated.

Secondly, since the counterbore 6 is exposed to the outside, it is necessary to refill the counterbore 6 with a material similar to the base material. However, if the wall panel is exposed to the open air for a long period of time, the wall panel may deteriorate and not only look good, but also cause water leakage from a gap between the two materials.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a wall panel mounting structure in which a base material is less likely to be destroyed and the appearance of an exposed surface to the outside is prevented from deteriorating and water leakage is prevented.

[0006]

The invention of this claim 1 [Summary of], in order to solve the above problems, short of ALC lateral wall panel 25
Rutotomoni been drilled blind holes 27 therewith perpendicular to the side small surface 26, a hollow rod Joa anchor member 29 inserted into the blind hole
Reinforcements embedded in the ALC side wall panel 25
The base end 34 is directly or indirectly locked to the streak 35, and the base end 34 is locked to the building structural member 23 in the middle of the hollow bar-shaped anchor member with respect to the directly threaded female screw 30. - the distal end portion 33 of the hook bolt 31 which forms a side L-shape being fixed to adopt a mounting structure of the ALC lateral wall panels are screwed.

[0007]

According to the first aspect of the present invention, the tip of the hook bolt in the prior art engages with the anchor member inserted into the blind hole formed from the short side of the ALC wall panel inside the panel. So it is not exposed on the front side of the panel. There is no need for counterbore holes that are exposed to the outside .

[0008]

Next, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, in the wall panel mounting structure of this embodiment, one end of a flange 22 of a stud 21 made of H-shaped steel as one end of a structural skeleton of a building is provided with the same type of structural skeleton as described above. A shape steel 23 having an L-shaped cross section is vertically fixed by welding.
The two ALC lateral wall panel 25 as ALC wall panel to the flange portion 24 of which is not welded with the stud 1 of the flange portion of the shaped steel 23 is Tatekoma.

The small side surface 26 on the short side of the ALC side wall panel 25
A blind hole 27 is formed in an in-plane direction (a direction perpendicular to the thickness direction of the panel) from the ALC side wall panel 2.
A counterbore (not shown) is drilled from the indoor surface of No. 5 in the thickness (out-of-plane) direction, and intersects with the blind hole 27 inside the ALC wall panel 25.

An anchor member 29 made of hollow rod-like steel is inserted into the blind hole 27 as shown in FIG. At the center in the longitudinal direction of the anchor member 29, a female screw 30 is threaded in the diameter direction. The female screw 30 can be screwed with a male screw 33 that is threaded on the tip of the hook bolt 31 having the L-shaped side surface on the tip end side main body 32 side. The anchor member 29 and the hook bolt 31 are engaged, and the former functions as the latter anchor.

The distal end body 32 of the hook bolt 31 is rotated to lock the proximal end 34 of the hook bolt 31 bent at 90 degrees from the distal end body 32 to the flange 24 of the shaped steel 23. When the hook bolt 1 is fixed by welding to stop the rotation, the ALC side wall panel 5 is formed as a part of the structural frame through the shape steel 23, the hook bolt 31, the anchor member 29 and the blind hole 27. The steel 23 is fixed to the stud 21.

The mounting structure thus formed and A
In the work of attaching the LC side wall panel to the structural body, the following operation and effect are exhibited. First, the number of components of the mounting bracket is very small, that is, the number of components is the anchor member 29 and the hook bolt 3 having a male screw at the tip.
There is only one. Unlike the prior art, no washer is required. Next, the mounting operation is the minimum welding operation necessary to stop the formation of the blind hole 27 and the counterbore hole and the rotation of the hook bolt. Since the digging hole is not exposed on the surface of the ALC side wall panel 25 fixed to the studs 21 as a structural frame, not only does the appearance of the ALC wall panel 25 not deteriorate, but also the prior art is used for a long time. There is no need to worry about water leakage.

The present invention is not limited to the above-described embodiment, but can be implemented with some modifications. For example, A
The above-mentioned structure is provided on both sides of the LC side wall panel 25, respectively.
Ru can be provided locations or multiple locations. Off Kkuboruto 3
When the distal end side main body 32 is rotated, its base end 34
And If the difficult gap to fill welding between the flange portion 24 is produced, Ru can also be inserted an appropriate spacer into the gap.

In this embodiment and in the embodiments of FIGS.
The anchor member 29 to the reinforcement 35 is embedded in the ALC wall panel 25, it to is sealed directly or indirectly engaged.

[0015]

As described above in detail, the present invention is excellent in that the base material constituting the wall panel is hardly broken, and the appearance of the exposed surface to the outside and the occurrence of water leakage can be eliminated. It has the effect.
