強いられ、不経済極りない。However, the pinning method using these pins has the following common disadvantages. In other words, the floating part repaired by pinning is finally completely fixed, but if external force such as temperature, humidity difference or earthquake is applied after that, the repaired part can no longer absorb the movement. Adverse effects (stress transfer phenomena) on the normal wall portion of When an adhesive such as an epoxy resin is used in combination to increase the holding force of the pin, the risk is further increased. In order to eliminate the fear, unnecessary work such as performing preventive pinning on the surrounding wall is forced, which is extremely uneconomical.

する。SUMMARY OF THE INVENTION The present invention has been made to overcome the above-mentioned deficiencies of the prior art. In a pinning method for repairing a floating mortar wall, the present invention is directed from a mortar floating portion to a concrete ground. Pins are stably embedded in the drilled pin holes, and the pins are allowed to move relative to each other even after being fixed, thereby preventing stress-induced transfer to the mortar wall portion that has not landed. Attempts to provide guard pins that make preventive pinning unnecessary.

陸転移現象）を及ぼすことを防止することができる。In order to use the guard pin of the present invention, as shown in FIG. 2, a cutting groove 8 is formed in the mortar floating portion, and a mortar wall layer M is penetrated at the center position of the cutting groove 8. Further, a punching hole 9 slightly narrower than the side width of the pin dug into the concrete base C is formed. This tapping pin position marker
King is the standard about 2 per six 1m. The depth of the hole is set to be 2-3 mm deeper than the entire length of the guide pin, and if necessary, water washing is performed. Then, an appropriate amount of the polymer mortar slurry 10 is injected into the pin hole 9. This injection is performed by using an oil dropper to wash out the inside of the hole. The steps up to here are almost the same as those in the conventional pinning method except for the use of the polymer mortar slurry. If a polymer mortar slurry is used as a curing agent, there is an advantage that the strength after curing does not change even if there is residual moisture in the pin hole 9. Immediately after completion of the above steps, the guard pin of the present invention is inserted into the pin hole 9 by a metal hammer.
Drive in. Since the driving is performed through the triangular arrow feather portion 6 having a vertex O at the rear end of the arrowhead portion 2, the vertex O is on the extension line in the arrowhead direction bisecting direction of the sharp portion 3 which is twice the lateral width of the arrowhead portion 2. In combination with the propulsion of the sharp portion 3 at the tip, the operation is performed smoothly and efficiently. When the driving is completed, a part of the polymer mortar slurry 10 overflows out of the pin hole 9,
The remaining polymer mortar slurry 10 is settled below the arrowhead 2 (including the gap between the locking teeth 4) as shown in FIG. Even before the polymer mortar slurry 10 is hardened, the interlocking teeth 4 projecting below the front body 2a of the arrowhead portion 2 at a comb-like interval have an infinitely narrow rearward angle with respect to the arrowhead direction. Has an acute angle α close to the above, the check action against the bottom wall of the pin hole 9 acts in several steps to generate a horizontal holding force. Further, since it has a clearance by the shallow meat stealing 5 along the upper edge of the upper rear half 2b as well as the lower side of the arrowhead portion 2, after fixing, the repaired portion further has an external force such as temperature, humidity change or vibration. In addition, these movements can be absorbed in the vertical direction, so that adverse effects (floating displacement phenomenon) can be prevented from being exerted on wall surfaces other than the repair site, especially around the repair site.

工により安価に量産できる。The present invention is as described above. In the pinning method for repairing a floating mortar wall, embedding of a pin into a pin hole drilled from a mortar floating portion toward a concrete base is stably maintained, and After the fixation, the pins are allowed to move relative to each other to prevent stress transfer to the portion of the mortar wall that has not landed, thereby eliminating so-called preventive pinning. The economic effect of this is immense. The construction technique can be performed without skill. The pins themselves can be mass-produced at low cost by metal stamping.
