PROBLEM TO BE SOLVED: To provide a method for greening a wall surface of a building, improving safety in working, shortening a working process to allow work by a small number of workers, and excellent in workability.SOLUTION: This method for greening a wall surface of a building includes arranging in a standing condition a framework scaffold 13 along the inside of a temporary enclosure 11 set for dividing a construction site from the outside, and temporarily constructing on the upper part of the framework scaffold 13, a planter unit 20 made of a planter 21, a box-shaped planter part 22 with an upper part opened to hold the planter 21, and a panel part 23 provided in a stretched state with a mesh 29 for letting a plant 34 vegetating on the planter 21 climb. Furthermore, the method includes precedently cultivating the plant of the planter 21 in a temporary place, letting the plant 34 climb on the mesh 29, and removing the planter unit 20 precedently cultivating the plant from the framework scaffold 13 followed by lifting when dismantling a scaffold 36 set along the wall surface of the building 35, and transferring the unit to the prescribed installation location of the wall surface of the building 35.COPYRIGHT: (C)2013,JPO&INPIT【課題】作業時の安全性を向上させ、作業工程を短縮して、少ない作業員で作業を可能にし、施工性が良好な建物の壁面緑化方法を提供する。【解決手段】建設現場を外部と区画するために設けられる仮囲い11の内側に沿って枠組足場13を立設し、該枠組足場13の上部に、プランター21と、該プランター21を収納すべく上部が開口した函形のプランター部22と、プランター21に植生する植物34を登はんさせるためのメッシュ29を張設したパネル部23とから構成されるプランターユニット20を仮設し、プランター21の植物を、仮設場所において先行栽培して、メッシュ29に植物34を登はんさせ、当該植物を先行栽培したプランターユニット20を、建物35壁面に沿って設けた足場36解体時に、枠組足場13から取り外して揚重し、建物35壁面の所定の設置位置に移設する。【選択図】図2
