PURPOSE:To heighten holding power by arranging a locking part to lock a main body on an anchor outer pipe in which the anchor main body is inserted, and constituting so that when force not less than a prescribed value is applied to the main body, the locking part is deformed and the main body is further inserted. CONSTITUTION:A head part 4 is fixed to a base end part of a body part 3, and a forked part 5 having a notch groove 5a having a length L is arranged between a pair of leg parts 5b on the other end, and an anchor main body 1 is formed. A tapering part 6 is arranged in a tip part of a circular pipe, and a recess part 7 composed of an opening hole 7a and a taper part 7b is arranged, and a recessed groove 8 having a step part is arranged in a position separated by a length L from the recess part 7. A collar part 9 is arranged in a base end part of the circular pipe, and an anchor outer pipe 2 is formed. In the case of work execution, the outer pipe 2 is driven in an ALC, and when the main body 1 is inserted and driven in the outer pipe 2, the step part of the recessed groove 8 is deformed, and the forked part 5 is derived outside from the opening hole 7a while curving, and expands in the ALC through the taper part 7b.

Next, a method of using the anchor having the above structure will be described. (1) First, the anchor body 1 is inserted into the anchor outer tube 2. The inner diameter D 2 of the outer anchor tube 2 is larger than the outer diameter D 1 of the anchor body 1, but a step portion 8a is partially formed on the inner periphery of the outer anchor tube 2, so that the anchor body 1
The anchor body 1 cannot be inserted unless the cut groove 5a is engaged with the stepped portion 8a. When the anchor body 1 is further advanced by the length L in the state where the cut groove 5a and the step portion 8a are engaged with each other, the base end portion 5d of the bifurcated portion 5 and the step portion 8a are locked so that further insertion is not possible. Be blocked.

On the other hand, an opening hole 7a is formed at a position separated from the step portion 8a of the concave groove 8 by L and orthogonal to the step portion 8a. Therefore, in the state where the insertion is blocked by the locking of the base end portion 5d of the forked portion 5 and the step portion 8a of the anchor outer tube 2, the tip 5c of the forked portion 5 passes through the opening hole 7a of the recess portion 7. And comes into contact with the tapered portion 7b (see FIG. 8).

(2) Next, the angle (or square bar) 13 to be fixed is placed on the surface of the ALC 14, and the angle 13 is fixed.
The anchor body 1 and the anchor outer tube 2 are driven into the ALC 14 through the holes formed in the ALC 14 (see FIG. 9). In this case, the head 4 of the anchor body 1 is hit with a hammer or the like,
Since the ALC 14 is relatively soft, it is driven into the ALC 14 while the engagement between the base end portion 5d of the anchor body 1 and the step portion 8a of the anchor outer tube 2 is maintained.

Then, as shown in FIG. 9, the collar portion 9 of the anchor outer tube 2 is brought into contact with the surface of the angle 13 in due course. After that, when the head 4 is further hit with a hammer or the like, the step portion 8a formed on the inner peripheral surface of the anchor outer tube 2 is deformed by the body portion 3 of the anchor body 1, and the anchor body 1
The locked state of will be exceeded.

Therefore, the anchor body 1 is further inserted into the anchor outer tube 2, and the forked portion 5 of the anchor body 1 is curved and led out to the outside from the opening hole 7a of the anchor outer tube 2. Will be. That is, the bifurcated portion 5 of the anchor body 1 spreads into the ALC 14 using the tapered portion 7b of the anchor outer tube 2 as a guide passage, and the angle 1
2 and the ALC 13 are more firmly fixed (see FIG. 10).

[Second Embodiment] FIG. 11 shows another embodiment of the present invention, in which the opening hole 7 of the outer anchor tube 2 is formed.
An embodiment in which a stopper member 15 is fitted to the portion a is shown. The stopper member 15 has a rectangular main body portion 15a provided with two opening holes 15b. Here, the opening hole 15b is formed in a size that allows the tip 5c of the forked portion 5 of the anchor body to pass through, but does not allow the leg portion 5b to pass through.

Since the recess 7 needs an opening hole 7a into which the stopper member 15 can be fitted, the opening hole 16 is formed prior to the formation of the recess 7 (see FIG. 12).
Then, it is necessary to form the opening hole 7a and the tapered portion 7b by the press heads 10 and 11 as shown in FIG.

The anchor according to this embodiment is characterized in that it can be used in addition to ALC, and its handling method is as follows. (1) First, the anchor body 1 is inserted into the outer anchor tube 2 while engaging the cut groove 5a of the anchor body 1 with the step portion 8a of the outer anchor tube 2. Then, the tip 5c of the anchor body 1 is locked to the taper portion 7b of the recess 7 and is more firmly locked by the stopper member 15.

(2) In this state, as in the case of FIG. 9, the head 4 of the anchor body 1 is hit with a hammer or the like. In the case of this embodiment, since the anchor body 1 is prevented from entering by the stopper member 15, even if the symmetric object into which the anchor is driven is harder than ALC, until the driving of the outer anchor tube 2 is completed. There is no fear that the tip portion 5c of the bifurcated portion 5 will start to spread.

As described above, the curved deformation anchor according to the present invention comprises an anchor body having a leg portion and a body portion, a tip portion, a guide passage, an opening hole, a locking portion and a base end portion. It consists of an anchor outer tube. Then, when a force of a predetermined value or more is applied in a state where the anchor main body is inserted into the anchor outer tube, the locking portion is deformed, the anchor main body further enters, and the leg portion is pulled out from the guide passage, so that the leg portion is It is designed to be curved and deformed. Therefore, even when a fixed object is attached to ALC or the like, the anchor is ALC
It can be curved and deformed inside, and the attached state can be secured.
