ある。[Effects of the Invention] Since the invention is as described above, the following effects can be obtained. <A> Conventionally, there was no technical idea of installing a jig for corrosion prevention and reinforcement at the boundary portion between the embedded portion and the exposed portion of the anchor pin for fixing the method frame. Therefore, there is a possibility that the anchor pins may be corroded by the intrusion of rainwater or the like, and the yield strength of the legal frame may be reduced. However, according to the present invention, by installing a jig at the boundary portion of the anchor pin, the contact with the anchor pin can be blocked even if rainwater or the like enters. Therefore, it is possible to prevent corrosion of the anchor pin and prevent a decrease in yield strength of the legal frame. Also,
By mounting the jig, it is possible to support the anchor pin upright and improve the anchoring stability of the anchor pin.
