WATERING STRUCTURE IN WALL SURFACE GREENING DEVICE

PROBLEM TO BE SOLVED: To enable a user to individually install and remove each greening unit and each watering pipe when installing watering pipes for watering nursery beds, in a structure in which greening units formed by supporting the nursery beds with frame materials are mounted to mounting bases to which vertical greening devices for greening the vertical surface of a building are fixed to the vertical surface in such a manner of facing horizontally.SOLUTION: A mounting base 15 is provided at its lower part with pipe support pieces 15k and 15j having the width to house a watering pipe 18, the opposite distance of the pipe support pieces becoming narrower as nearing the lower end. The end parts of the pipe support pieces 15k and 15j form a pipe support groove 15e having an opening 15i whose opening size is smaller than the external diameter of the watering pipe 18. The watering pipes are disposed in the pipe support grooves 15e. 【課題】建造物の縦面を緑化するための縦面緑化装置を、水平方向を向く状態で縦面に固定される取付け下地に、苗床を枠材で支持してなる緑化用ユニットを取付けて構成したものにおいて、苗床に灌水するための灌水パイプを設けるにあたり、緑化用ユニットと灌水パイプとのそれぞれを単独で取付け、取外しできるようにする。【解決手段】取付け下地１５に、灌水パイプ１８を収納できる広さを有し、下部に下側ほど対向間隔が幅狭となるパイプ支持片１５ｋ、１５ｊが設けられ、該パイプ支持片１５ｋ、１５ｊの下端が、灌水パイプ１８の外径よりも小さな開口寸法で開口１５ｉしたパイプ支持溝１５ｅを形成し、該パイプ支持溝１５ｅに灌水パイプ１８を配設した。【選択図】図１５
