< Topic >The component, offers the raft for cultivation where worker can work safely on the raft for cultivation even with the material which elasticity it is easy to become deformed.SolutionsWith component 1 of long shaku of plural books which elasticity it is easy to become deformed plural frameworks it does the framework body in rectangular condition, specified interval placing the component 1 that plural framework bodies in parallel with cube type connected tool, 2 it connects, it connects the component 1 which it adjoins with the corner perpendicularly with corner connected tool, 4 cube type connected tool 2 or corner connected tool 4 or facilities does float 7 in the framework body. Cube type connected tool 2 designates 2 these tube bodies in order to pass through component 1 in parallel as the structure which is connected to cube type condition with the frame of pair, corner connected tool 4 makes the structure which connects the plural tube bodies of L type in order to pass through both components 1 from perpendicular direction with the plural frames, that cube type connected tool installs foothold board 5 on the frame of 2 and corner connected tool 4.< Selective figure >Figure 5【課題】部材が弾性変形しやすい材質でも、作業者が養殖用いかだ上で安全に作業できる養殖用いかだを提供する。【解決手段】弾性変形しやすい複数本の長尺の部材1で枠体を矩形状に複数枠組みし、その複数の枠体の並行する部材1同士を井形連結具2で所定間隔おいて連結し、コーナーで隣接する部材1同士をコーナー連結具4で直角に連結し、井形連結具2又はコーナー連結具4又は枠体にフロート7を吊設する。井形連結具2は、部材1を通すための並行する2本の筒体を一対のフレームで井形状に連結した構造とし、コーナー連結具4は、双方の部材1を直角方向から通すためのL型の複数の筒体を複数のフレームで連結した構造とし、その井形連結具2及びコーナー連結具4のフレーム上に足場板5を取り付ける。【選択図】図5
