もに係止部１４を目地部１９に結合させる。If peeling occurs between the concrete body 16 and the mortar 17 or between the mortar 17 and the surface finishing material 18 in the concrete structure 15 having such a configuration, the surface finish may be removed from the joints 19 on the surface of the surface finishing material 18). A repair hole 20 is drilled through A18, the mortar 17, and the concrete body 16, and the joint portion 19 opened by the repair hole 20 is opened in the length direction j! = 45M, which is slightly longer than the length of the locking part 14. Next, after injecting an adhesive 21 such as epoxy adhesive into the repair hole 20, the insertion portion 13 of the repair fitting 11 is inserted. Then, the locking portion 14 of the repair fitting 11 is fitted into the removed joint portion 19 to support the surface of the surface finishing material 18. Furthermore, the adhesive 21 is filled into the removed joint portion 19 to be integrated with the adhesive 21 in the repair hole 20, and the locking portion 14 is coupled to the joint portion 19.

ることがない。In this way, the insertion part 13 of the repair fitting 11 is bonded into the concrete body 16 by the adhesive 21, and the locking part 14 of the repair fitting 11 supports the surface of the surface finishing material 18 as shown in FIG. Since the concrete body 16 is integrally bonded with the adhesive 21, the mortar 17 and the surface finishing material 18 are prevented from peeling off from the concrete body 16. Furthermore, the locking portion 14 is located at the joint portion 19.
Since it is embedded in the adhesive 21, it is not exposed on the surface of the surface finishing material 18, and the appearance is not spoiled by the locking part 14.

１に対しては結合効果がないことを示している。The results of the above tests showed that when the method of the present invention was used, the surface finishing material 18 had a high retention effect and a high bonding force with the concrete body 16. The conventional method also shows that although the pin 8 is fixed to the concrete body 3, it has no bonding effect on the facing material 1.

仕上材の外面に係合し表面仕上材をコンクリート体に保
持させる作用をし、表面仕上材の剥離が防止される。According to the present invention, the insertion portion of the repair fitting is bonded to the concrete body through an adhesive, and the locking portion orthogonal to the insertion portion engages with the outer surface of the surface finishing material to hold the surface finishing material on the concrete body. This prevents the surface finish material from peeling off.

を害なうこともない。In addition, since the repair holes and joints are integrally filled with adhesive, it is possible to block the intrusion of rainwater into the concrete body and mortar and the influence of carbon dioxide gas in the atmosphere. It stops corrosion and prevents deterioration of the side bars of hardware receivers, and also prevents neutralization of the surface finishing material itself, which has the effect of preventing corrosion of the surface finishing material. Furthermore, since the locking portion of the repair fitting is buried in the adhesive at the joint, the aesthetic appearance of the surface finishing material is not impaired.
