PROBLEM TO BE SOLVED: To provide an elevated cultivation bed apparatus having a simple structure, and an effective cultivation area efficiently formed by a low cost, and enabling a large cultivation yield to be expected even by a small-scale greenhouse formed by reducing an installation space.SOLUTION: The elevated cultivation bed apparatus includes a plurality of vertical pipes for support, a plurality of additional U-shaped arms orthogonally arranged on horizontally laid arms at an interval in the longitudinal direction of the horizontally laid arms, bent into the U shapes at the center parts so that a medium sheet and a liquid-receiving sheet laid at an interval in bent shapes so as to form double layers may be supported by the upper surface sides, and having arm-engaging parts one part of which detachably engages with a body side part of one arm in the two base horizontally laid arms, and insertion engaging parts by which the other part is engaged by insertion with one of the plurality of the vertical pipes, and additional horizontally laid arms integrally connected to the additional U-shaped arms in a state parallel to the two base horizontally laid arms at the insertion engaging part sides of the additional U-shaped arms.COPYRIGHT: (C)2013,JPO&INPIT【課題】 簡単な構造で低コストにより、有効栽培面積を効率的に形成し得ると同時に設置スペースを小さくして小規模ハウスでも大きな栽培収量を期待できる高設栽培床装置を提供する。【解決手段】 高設栽培床装置において、支持用の複数の縦パイプと、横架アームの長手方向に間隔をあけて複数個が横架アームに直角状に配置され、培地シートと液受シートを間隙を設けて2層に撓ませた状態で、上面側で支持するように中央部がU字状に曲成された追加U字状アームであり、一部が2本の基本横架アームのうちの1つのアームの胴側部に着脱可能に嵌合するアーム嵌合部と、他部が複数の縦パイプ中の1つに差込嵌合する差込嵌合部と、を有する追加U字状アームと、追加U字状アームの差込嵌合部側において2本の基本横架アームに平行な状態で追加U字状アームに一体的に連結された追加横架アームと、を有する。【選択図】図1
