An anchor plug 4 is inserted to the prepared hole 7 through a washer 5 and a bracket 6 to the bottom of the hole 7. Next, by fastening the anchor plug 4, the anchor plug 4 is inserted through the lath 8 embedded in the ALC panel 1, and an extending part 4a provided at the top of the anchor plug 4 is gradually extended. By fastening the anchor plug 4 to its root, the bracket 6 is fixed, and the anchor plug 4 is securely fixed to the ALC panel 1. At this time, the extending part 4a of the anchor plug 4 is engaged to the lath 8 to be prevented from slipping off.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anchor mounting structure for an ALC panel and a mounting method for directly mounting a base metal material such as an exterior material (sticking on stone) or an interior material to the ALC panel.

[0002]

2. Description of the Related Art Conventionally, an anchor mounting structure for an ALC panel has a structure as shown in FIG. 6, for example. In FIG. 6, an ALC panel 20 in which reinforcing reinforcing bars 21 are embedded,
It is composed of anchor anchors 22 driven from the surface of the LC panel 20. The anchor retainer 22 has an anchor plug 23 and a washer 25, and the anchor plug 23 has an expanded portion. The expanded portion is a portion where a part of the anchor plug expands due to resistance or stress.

In the figure, A in which a reinforcing bar 21 is embedded
From the surface of the ALC panel 20 to the LC panel 20, the pilot hole 2
7, the anchor plug 23 is driven in via a washer 25 and a base metal 24 such as L-shaped steel to which an outer wall material such as a decorative plate is attached. As the anchor plug 23 is driven into the ALC panel 20,
The expanding portion receives resistance from the panel and expands and is fixed.

There has also been a mounting structure in which an anchor plug is directly driven and mounted without providing a pilot hole in the ALC panel.

[0005]

The anchor mounting structure as described above bears the pulling force and the shearing force at the unreinforced portion of the ALC panel, and when the ALC panel breaks, the structure shown in FIG. As shown in FIG. 3, a fracture surface 26 having an inclination of about 45 ° or more is formed from the tip of the anchor plug 23,
Since both the pull-out strength and the shear strength are insufficient, there is a risk that the anchor locking device may fall, especially in the fabrication on the exterior material or the interior side, and the yield strength is limited. In addition, since the penetration type anchor also requires work on the indoor side, there was a problem that it could not be installed if there was a small clearance with the back of the pillar or interior such as extension and renovation.

[0006] The present invention provides an ALC anchor mounting structure and mounting method which can be carried out with high yield strength and high reliability.

[0007]

An anchor mounting structure for an ALC panel according to the present invention is an ALC panel in which a lath net is embedded, and is inserted from the surface of the ALC panel, and an expanding portion is engaged with the lath net. It has a locking tool for an anchor. The anchor mounting method of the ALC panel of the present invention is
Forming a pilot hole in an ALC panel in which a lath net is embedded, inserting an anchor locking device having an expanding portion into the pilot hole, and then expanding the expanding portion to engage the lath net. It is characterized by.

[0008]

According to the present invention, a pilot hole is formed in an ALC panel in which a lath net is embedded, an anchor locking device having a widened portion is inserted from the surface of the ALC panel, and the widened portion is widened. Then, since it engages with the lath net, it is possible to securely and stably fix the anchor fastener to the ALC panel. And
With this anchor locking tool, a base metal or the like can be attached and fixed.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a partial cross-sectional view of each part constituting the anchor mounting structure of the present invention. In the figure, a reinforcing reinforcing bar 2 and a lath net 8 are embedded in an ALC panel 1,
A lower hole 7 is drilled to the vicinity of the lath net embedding. The anchor retainer 3 is composed of an anchor plug 4 and a washer 5, and the base metal 6 is fixed by the anchor retainer 3. The anchor plug 4 is configured to be expanded when the expanded portion 4a receives resistance. The lower hole 7 is preferably formed up to the position of the lath net 8 in the ALC panel 1, but it may be formed before and after that.

FIG. 2 is a partial sectional view showing the anchor mounting structure of FIG. In the figure, lath net 8 and reinforcing bar 2
Embedded in the ALC panel 1, a pilot hole 7 drilled from the surface of the ALC panel 1, and an anchor member inserted from the pilot hole 7 and having the expanding portion 4a expanded and engaged with the lath net. It is composed of a stopper 3 and a base metal 6 fixed by the anchor stopper 3.

The anchor locking device 3 is composed of an anchor plug 4 and a washer 5, and the anchor plug 4 has a widened portion 4.
a. The expanded portion 4a of the anchor plug 4 is AL
It is configured such that it is expanded at a position where it passes through the lath net 8 embedded in the C panel 1, and the main bearing portion of the anchor plug 4 is located on the back side of the lath net 8.

Incidentally, FIG. 3 shows a partial perspective view of FIG. In order to obtain the configuration as shown in FIG. 2, first, the ALC panel 1 in which the reinforcing reinforcing bars 2 and the lath net 8 are embedded is provided with a pilot hole 7 in a direction perpendicular to the lath net 8. The anchor plug 4 is inserted into the pilot hole 7 through the washer 5 and the base metal 6 to the depth of the pilot hole 7. Next, by tightening the anchor plug 4, it penetrates the lath net 8 in the ALC panel 1,
The expansion portion 4a at the tip of the anchor plug 4 gradually expands. By tightening this anchor plug 4 to the root, the base metal 6 is fixed, and the anchor plug 4 is AL
It is fixed to the C panel 1. At this time, the expanded portion 4a of the anchor plug 4 is engaged with the lath net 8 so as not to come off.

Examples of the anchor plugs that can be used in the present invention include, for example, Fisher Germany Wester Fisher Fisher Plugs (for example, MS type and S type), Wakai Sangyo Co., Ltd. Anchors (for example, Hit Nail and Tatuck), and Sanko Industry. Anchor manufactured by a corporation (eg SET anchor,
Cut anchors), manufactured by Naniha Construction Equipment Co., Ltd. (for example, Tylock anchors), and the like.

The anchor plug 4 is of the bolt type in this example, but may be of the pin or screw type. The pin type anchor is attached by hammering it in. 4 and 5 are partial cross-sectional views showing another embodiment of the panel anchor mounting structure. Figure 4
This is an example in which only the lath net 8 is embedded in the ALC panel 9.
A pilot hole 7 is formed in the ALC panel 9 to the back of the lath net 8,
An anchor plug 11 is inserted into the lower hole 7 via the base metal 6 and the washer 5. Anchor plug 11 of this example
Is constructed by winding plastic around a bolt.

First, the anchor plug 11 is inserted into the pilot hole 7 through the washer 5 and the base metal 6, and the anchor plug 1
Tighten 1. When the anchor plug 11 is tightened, the plastic portion of the lath net 8 contracts and expands at the back of the lath net 8, and the anchor plug 11 is engaged with and fixed to the lath net 8. By strongly tightening the anchor plug 11, it is fixed to the ALC panel 9 and the base metal 6 is fixed.

FIG. 5 shows an example of the ALC panel 1 shown in FIG. 2 in which the lath net 8 is located off the center. The position of the lath net in the ALC panel can be embedded at any position depending on the type of anchor plug.

[0017]

According to the anchor mounting structure and mounting method for an ALC panel of the present invention, it is possible to bear an external force that acts on the anchor locking device at the lath net portion of the ALC panel,
The mounting strength to the ALC panel can be increased. Further, even if the ALC panel to which the anchor locking device is attached breaks, the anchor locking device is physically caught by the lath net, so that it does not fall off. Further, since it is not necessary to penetrate the anchor locking device, it can be easily attached by an operation from the inside of the room, and can be attached at an arbitrary position.
