| description | To more effectively prevent invasion of a deterioration factor.SOLUTION: In an arrangement process, a pair of precast concrete members 1 with a joint member 1j projecting from an end face 1e are arranged so that the respective joint members 1j face each other; by a filling formation process, in a construction method of the precast concrete member in which a filling part 2 is formed by filling a filling material 2f in a space 1s between end faces 1e of the pair of precast concrete members 1; by a cover layer forming process, a cover layer 4 is formed by placing ultra-high strength fiber reinforced concrete 4f or high-strength fiber reinforced mortar above a pair of the precast concrete members 1 and the filling part 2 so as to straddle the end face 1e which is a boundary face between the pair of the precast concrete members 1 and the filling part 2. Since the cover layer 4 made of the ultra-high strength fiber reinforced concrete 4f having high durability is formed, invasion of deterioration factors can be more effectively prevented.SELECTED DRAWING: Figure 5
【課題】劣化因子の侵入をより効果的に防止する。【解決手段】配置工程により、端面１ｅから継手部材１ｊが突出した一対のプレキャストコンクリート部材１が継手部材１ｊのそれぞれが対向するように配置され、間詰形成工程より、一対のプレキャストコンクリート部材１の端面１ｅの間の空間１ｓに充填材２ｆが充填されることにより間詰部２が形成されるプレキャストコンクリート部材の施工方法において、かぶり層形成工程により、一対のプレキャストコンクリート部材１と間詰部２との境界面である端面１ｅを跨ぐように、一対のプレキャストコンクリート部材１及び間詰部２の上方に、超高強度繊維補強コンクリート４ｆ又は高強度繊維補強モルタルが打設されることによりかぶり層４が形成される。耐久性が高い超高強度繊維補強コンクリート４ｆ等によるかぶり層４が形成されるため、劣化因子の侵入をより効果的に防止することができる。【選択図】図５ |
