PROBLEM TO BE SOLVED: To provide a wall surface greening unit capable of improving handling properties of a culture soil base, preventing damage, and attempting cost lowering.SOLUTION: This wall surface greening unit 10 is supported with a support member which is fixed on a wall surface of a structure and set in a hanging condition along the wall surface so as to apply greening to the structure. The greening unit has a culture soil base 12 to be given with planting, and a fixing tool 13 for holding the culture soil base 12 to make the support member support in a hanging condition. The culture soil base 12 is made by unitedly forming heat fusion culture soil 14 which contains heat fusion fiber and is solidified by heat treatment, and a tray 15 which holds the heat fusion culture soil 14. The fixing tool 13 has a pair of vertical parts 13a and 13b, and a horizontal part which connects the lower edges of a pair of the vertical parts 13a and 13b, and is formed in an almost U shape and belt-like shape, and is inserted into between a pair of the vertical parts 13a and 13b so as to hold the culture soil base 12.COPYRIGHT: (C)2009,JPO&INPIT【課題】培土基盤の取扱性を向上させるとともに、損傷を防止することを可能にし、且つ低コスト化を図ることが可能な壁面緑化ユニットを提供する。【解決手段】構造物の壁面に固設した支持部材に支持されて壁面に沿って吊り下げ状態で設置することにより構造物に緑化を施す壁面緑化ユニット10であって、植栽が施される培土基盤12と、培土基盤12を保持して支持部材に吊り下げ状態で支持させるための固定具13とを備え、培土基盤12は、熱融着繊維を含み、加熱処理することで固形化する熱融着培土14と、熱融着培土14を収容するトレー15とが一体形成されてなり、固定具13は、一対の縦部13a、13bと一対の縦部13a、13bの下端同士を繋ぐ横部とを備えて略U字状で帯状に形成され、一対の縦部13a、13bの間に差し込むことで培土基盤12を保持する。【選択図】図2
