DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of mounting a locking member used when a wall panel is locked to a building frame, and a jig for inserting an anchor member therefor.

[0002]

2. Description of the Related Art FIG. 6 shows a known structure for locking a wall panel such as an ALC panel to a structural body of a building. That is, the blind hole 2 is formed in the wall panel 10 from the fore-edge surface, and the bolt hole 3 connected to the blind hole 2 is formed from the surface of the wall panel 10 facing the inside of the building. Then, a pipe-shaped anchor member 5 having a female screw portion 4 formed in the center is inserted into the blind hole 2, and a bolt 7 attached to the locking metal fitting 6 is inserted into the bolt hole 3, and the tip of the bolt 7 is anchored. The locking fitting 6 is attached to the wall panel 10 by being screwed into the female screw portion 4 of the member 5, and finally the locking fitting 6 is attached.
Is locked to the structural skeleton side.

[0003] In this structure, it is not necessary to make a hole in the surface of the wall panel outside the building, so that the appearance of the hole after the hole is backfilled may deteriorate or rainwater may enter through a gap between the backfill part. There is an advantage that you do not.
In addition, since the anchor member can be attached immediately before the wall panel is locked to the structural frame, there is also an advantage in construction such that the position of the anchor member can be easily changed.

[0004]

By the way, when the wall panel 10 is mounted with the above-described structure, the anchor member 5 is required.
Conventionally, the following method is used to screw the bolt 7 into the hole. First, the anchor member 5 is inserted into the blind hole 2 in a direction in which the female screw portion 4 faces the back side of the wall panel 10. And
While looking into the blind hole 2 through the bolt hole 3, the anchor member 5 is pushed into the blind hole 2 with a rod-shaped object, and the anchor member 5 is slowly moved to a position where the female screw portion 4 continues to the bolt hole 3. When the female screw portion 4 matches the bolt hole 3, the rod-shaped object is pulled out from the blind hole 2, the bolt 7 is inserted into the bolt hole 3 and screwed into the anchor member 5.

However, according to the above-described method, when the anchor member 5 is pushed into the blind hole 2 and the anchor member 5 goes a little too far through the bolt hole 3, it cannot be pulled back. Further, when the anchor member 5 is pushed in, it may rotate in the blind hole 2 and the direction of the female screw portion 4 may not match the bolt hole 3. If the insertion of the anchor member 5 fails as described above, it is necessary to tilt the wall panel 10 to strike out the anchor member 5 and to start over from the beginning, and there has been a problem that the operation is very troublesome.

The present invention has been made in view of the above circumstances, and in adopting the above-described wall panel mounting structure, the work of setting an anchor member at a predetermined position and locking a locking member here is simplified. It is an object of the present invention to provide a method of efficiently attaching a locking member to a wall panel and a jig for inserting an anchor member for the method.

[0007]

According to the present invention, there is provided a method of attaching a locking member to a wall panel, wherein the anchor member is inserted by press-fitting an anchor member and a holding portion provided at a distal end of an insertion jig. Holding the base side of the insertion jig, insert the front end side into the anchor insertion hole of the wall panel, position the anchor member at a predetermined position in the anchor insertion hole, and thereafter, The present invention is characterized in that the locking member is fixed to the second member (the invention of claim 1).

The insertion jig according to the present invention comprises a handle, a shaft extending from the handle and capable of being inserted into an anchor insertion hole of a wall panel, and an anchor member provided at a tip end of the shaft for press-fitting an anchor member. (A second aspect of the present invention). In this case, it is preferable that the holding portion is a metal pin that has a tapered shape and is pressed into the space of the anchor member (the invention of claim 3).

[0009]

According to the present invention, since the anchor member is held by the holding portion at the distal end of the insertion jig, the anchor member is inserted into the anchor insertion hole of the wall panel by holding the base side of the insertion jig. be able to. The insertion position of the anchor member can be adjusted freely by holding the base side of the insertion jig and changing the insertion depth. To adjust the rotation direction in the anchor insertion hole, also rotate the base side of the insertion jig By doing so, it is possible to freely perform the operation, and generally, the operation of fixing the locking member can be easily performed. In order to hold the anchor member in the holding portion of the insertion jig, the holding portion and the anchor member only have to be press-fitted, and to remove the holding portion from the anchor member, the anchor member has already been moved to the locking member side. Since it is fixed, if the insertion jig is simply pulled out from the anchor insertion hole, the press-fitting relationship with the anchor member can be easily removed.

Further, when the holding portion is a tapered metal pin, the holding portion is engaged with the metal anchor member with an appropriate frictional force. Also, the wear of the holding portion is reduced even if it is used repeatedly.

[0011]

As described above, according to the present invention, the anchor member can be easily held and detached from the insertion jig, and the anchor member can be placed at a desired position in the anchor insertion hole of the wall panel. Since the setting can be performed and the position can be adjusted easily, there is an effect that the operation of fixing the locking member can be performed efficiently as a whole. In particular, according to the insertion jig of the third aspect, the effect that the holding of the anchor member is ensured, the workability is further improved, and the durability is also excellent is obtained.
