PROBLEM TO BE SOLVED: To obtain a structure which is optimum for joining precast concrete walls without the necessity for elongating a joint length such as a lap joint.SOLUTION: An upper loop part (upper-side reinforcement) 4a is downwardly protruded from a lower end face 2a of an upper-side precast concrete wall 2, a lower-side loop part (lower-side reinforcement) 5a is upwardly protruded from an upper end face 3a of a lower-side prescribed concrete 3, and a slab reinforcement 6 is inserted into the upper-side loop part 4a and the lower-side loop part 5a. Unlike a lap joint, it is not necessary to elongate a joint length, and a structure which is optimum for joining the precast concrete walls can be obtained.SELECTED DRAWING: Figure 2 【課題】重ね継手のように継手長さを長くする必要が無く、プレキャストコンクリート壁の接合のための最適な構造を得ることができる。【解決手段】上側のプレキャストコンクリート壁２の下端面２ａからは上側ループ部（上側鉄筋）４ａを下方に突出させ、下側のプレキャストコンクリート壁３の上端面３ａからは下側ループ部（下側鉄筋）５ａを上方に突出させ、該上側ループ部４ａと該下側ループ部５ａとにはスラブ筋６を挿通させる。重ね継手のように継手長さを長くする必要が無く、プレキャストコンクリート壁の接合のための最適な構造を得ることができる。【選択図】図２
