EXFOLIATION PREVENTION METHOD
To provide an exfoliation prevention method that can be secured to be compatible with work's safety and adhesion workability of an exfoliation prevention sheet 2 even when applying an epoxy resin based adhesive 4 onto the surface of a concrete structure 1 located above worker's head.SOLUTION: An exfoliation prevention method for bonding an exfoliation prevention sheet 2 onto the surface of a concrete structure 1 to reinforce the surface of the concrete structure 1 comprises: a mixture step of mixing a high viscous and solid like hardening agent comparative to a liquid hardening agent in a high viscous and solid like main agent comparative to a liquid main agent to form an epoxy resin based adhesive 4; an application step of applying the epoxy resin based adhesive 4 to the surface of the concrete structure 1 or the exfoliation prevention sheet 2; and an attachment step of attaching the exfoliation prevention sheet 2 onto the surface of the concrete structure 1.SELECTED DRAWING: Figure 4
【課題】作業員の頭上に位置するコンクリート構造物１の表面にエポキシ樹脂系接着剤４を塗布する場合であっても、作業の安全性と剥落防止シート２の接着作業性とを両立して確保できる剥落防止工法を提供することを目的とする。【解決手段】コンクリート構造物１の表面に剥落防止シート２を接着して、コンクリート構造物１の表面を補強する剥落防止工法であって、液状の主剤に比べて高粘性で固体状の主剤に、液状の硬化剤に比べて高粘性で固体状の硬化剤を混ぜ合わせてエポキシ樹脂系接着剤４を生成する混合工程と、エポキシ樹脂系接着剤４を、コンクリート構造物１の表面または剥落防止シート２に塗布する塗布工程と、コンクリート構造物１の表面に剥落防止シート２を貼付する貼付工程とを行うことを特徴とする。【選択図】図４
