る。With box-cut anchors, it is common to create irregularities in the hole to be embedded in advance, but with adhesive anchors that are installed later, it is necessary to scrub the inside of the hole with a hard brush or mechanically create dents on the side of the hole. There are conventional methods for mechanically forming the recesses. The jig shown in Fig. 5 has a tapered end and a chevron-shaped protrusion 4 on the narrow part, and is lifted from the bottom of the hole while rotating the rotating machine and jig in a conical shape using the hole mouth as a fulcrum. The jig is roughly rotated. As a result, a large depression 5 is formed on the side surface of the hole as shown in FIG. 7th
The jig shown in the figure can be pressed against the bottom of the hole to remove the protrusion 4 on the side.
This is a sophisticated jig that expands and forms a widened hole 5 as shown in FIG. All of these conventional jigs are used to form large recesses on the side surfaces of holes.

It is thought that these methods can significantly increase the fixation strength of adhesive anchors, but
In reality, the physical properties of the adhesive are often weak, and the failure of the adhesive occurs before the failure of the base material, making it less effective to increase the resistance strength by greatly widening the hole. It is known that the concrete base material often has minute cracks due to shrinkage of the concrete over time, and cracks occur at the anchor position, greatly reducing the fixing force of adhesive anchors. It is expected that an effective way to deal with this problem would be to widen the inside of the anchor burial hole and use the snag to maintain its strength, but if the width is widened in one place, even if the expanded width is large, the stress will dent in the same way. 1
Since the adhesive is concentrated in one place, the adhesive breaks first and is not as effective.In such cases, it is estimated that increasing the number of expansion points on the side of the hole will result in a more stable and high-strength anchor. However, although it is possible to expand the holes at several locations on the side surface of the hole using conventional jigs, there is a problem in that the work is labor-intensive, and improvements to these problems are desired.

An object of the present invention is to provide a method for forming a hole for embedding an adhesive anchor and a forming jig that can reduce the force.

However, in the second embodiment, the dent can be made in one operation, so the workability is superior to that in the first embodiment. If there are minute cracks at the hole locations in the base material,
It can be seen that, as seen in Example 3 without a jig, the base material is no longer constrained and the strength is significantly reduced. However, it can be seen that the strength decreases less as the number of chips increases using the jig according to the present invention.
