PROBLEM TO BE SOLVED: To provide a wall surface greening device which keeps plants on the outer wall surface of a construction to be visible from outside of the construction and also prevents insufficient growth of the plants while reducing stress caused by wind and stress caused by sunshine that may act on the plants by increasing rigidity of protection plates to be capable of reliably receive wind pressure.SOLUTION: The wall surface greening device greens the outer wall surface of a construction. The device includes plants set out to face the outer wall surface, and protection plates disposed at positions outward more than the plants so as to face the plants and protecting the plants from wind and sunshine. The protection plates include perforated folded plates. The perforated folded plates have holes passing through the plates in the thickness direction of the plates and also have mountain-shape parts each inflected into a cross-sectional mountain shape.COPYRIGHT: (C)2013,JPO&INPIT【課題】保護板の剛性を高めて風圧を確実に受け止め可能にして、植物に作用し得る風起因のストレスや日射起因のストレスを軽減しながらも、構造物の外壁面の植物を構造物の外方から見える状態に維持するとともに、植物の生育不良を回避する。【解決手段】構造物の外壁面を緑化する壁面緑化装置である。前記外壁面に対向して設けられた植物と、前記植物よりも外方の位置に該植物に対向して配置され、該植物を風及び日射から保護する保護板と、を備える。前記保護板には、有孔折板が含まれる。前記有孔折板は、板厚方向に貫通する孔を有するとともに、断面山型形状に屈曲された山型形状部分を有している。【選択図】図3
