PROBLEM TO BE SOLVED: To effectively repair a lift part formed in a combined stone exterior wall. SOLUTION: A method of repairing the lift part of the exterior wall constructed by piling up bricks on a surface of a concrete skeleton includes an anchor pinning process, a water injection process and a resin injection process. In the anchor pinning process, pin holes are formed at appropriate positions in the area where the lift part is formed, in a manner that the pin holes penetrate from an outer surface of the exterior wall to the concrete skeleton. Then, an epoxy resin material having adhesiveness is injected into the pin holes, anchor pins are arranged in the pin holes, and then the epoxy resin material is cured. In the water injection process, injection holes are formed at appropriate positions in the area except the part where the anchor pins are arranged, in a manner that the injection holes penetrate from the outer surface of the exterior wall to the concrete skeleton, and then water is injected into the injection holes. In the resin injection process, a hydrophilic one-component polyurethane resin material having adhesiveness is injected into the injection holes. COPYRIGHT: (C)2007,JPO&INPIT
