JUNCTION STRUCTURE AND JUNCTION METHOD FOR PRECAST PLATE

To provide a junction structure and a junction method for precast plates, which can reduce the construction time when building side walls of a tank by using the precast plates and can obtain high bond strength with simple structure.SOLUTION: The junction structure of precast plates is the structure that builds side walls of a tank by abutting and stacking end surfaces of precast plates to each other. End surfaces 2 of precast plates 1 have projecting parts 6 where intermediate parts are protruded by way of cutout parts 5 provided at both ends in the longer direction of the end surfaces 2. Connection space 7 is formed by the cutout parts 5 caused by projecting parts 6 of adjacent precast plates 1 abutted to each other. The adjacent precast plates 1 have connection members 8 extending to the connection space 7. Connection means is provided for connecting the connection members 8 extending to the connection space 7 from the adjacent precast plates 1 to each other.SELECTED DRAWING: Figure 1 【課題】プレキャスト板によりタンクの側壁を構築する際の施工時間を短縮することができ、しかも簡単な構造で高い接合強度が得られるプレキャスト板の接合構造及び接合方法を提供する。【解決手段】プレキャスト板の端面を相互に当接して積み上げることによりタンクの側壁を構築するプレキャスト板の接合構造であって、プレキャスト板１の端面２には、端面２の長手方向両端部に備えた切欠部５により中間部が突出した突出部６を有し、隣接するプレキャスト板１の突出部６が相互に当接することで切欠部５による接続空間７が形成され、隣接するプレキャスト板１には接続空間７に延びる接続部材８を有し、隣接するプレキャスト板１から接続空間７に延びた接続部材８を相互に連結する連結手段を備える。【選択図】図１
