REPAIRING METHOD OF BUILDING FRAME DEGRADED PORTION AND REPAIR STATE INSPECTION METHOD
PROBLEM TO BE SOLVED: To provide a repairing method of a building frame degraded portion in which the sealing performance of a repair place of the building frame can be secured, and a repair state inspection method capable of inspecting a repair state simply and precisely.SOLUTION: A degraded portion 2 of a building frame 1 is chipped and a chipped groove 4 having an opening 4a is formed on the surface 1a of the building frame 1. Subsequently, foaming resin is injected and foamed from the opening 4a into the chipped groove 4. Substantially the entire of the chipped groove 4 is filled by the foamed resin and a portion of the foamed resin is made to come out from substantially the entire area of the opening 4a and cured. According to this configuration, the air in the chipped groove 4 is gradually extruded to an outer side with foaming inflation of the foaming resin, and it prevents the occurrence of air pockets in a foamed resin layer 10 in the chipped groove 4 and further prevents the occurrence of cavities in the building frame 1 due to the air pockets as much as possible. As a result, the sealing performance in the repair place is improved, the immersion of rain water in the building frame is prevented as much as possible, and the corrosion of rebar due to the dew condensation is prevented, and thereby building frame strength is maintained satisfactorily as the synergistic effect.SELECTED DRAWING: Figure 7
【課題】 躯体の補修箇所のシール性を確保し得るような躯体劣化部分の補修方法、並びに、補修状態を簡単且つ的確に検査し得る補修状態検査方法を提案する。【解決手段】 躯体１の劣化部分２を斫って該躯体１の表面１aに開口部４ａを有する削溝４を形成し、ついで、上記開口部４ａから、上記削溝４内に発泡性樹脂を注入して発泡させ、発泡した樹脂で上記削溝４の略全体を満たすとともに、該発泡した樹脂の一部を開口部４ａの略全域から外方へ溢出させて硬化させる。係る構成によれば、削溝４内の空気は、発泡性樹脂の発泡膨張に伴って次第に外方側へ押し出され、削溝４内の発泡樹脂層１０内に空気溜りが発生すること、さらにこの空気溜りに起因して躯体１内に空洞が発生することが可及的に防止され、この結果、補修箇所におけるシール性が向上し躯体内への雨水の浸み込みが可及的に防止されるとともに、結露による鉄筋の腐食が防止され、これらの相乗効果として、躯体強度が良好に維持される。【選択図】 図７
