A building planting wall structure is disclosed and is provided with a plurality of base plates. Longitudinal embedded slots are arranged in the front sides of the base plates and are used for arranging a plurality of planting pot nested groups provided with drainage pipes. A plurality of connecting pipe connecting groups are provided with drainage pipes of upper and lower planting pots so as to fix the distance between upper and lower planting pots. At least one drainage passage is disposed in the base plates. Tops and bottoms of the base plates are provided with water discharging covers and water feeding cork covers respectively. An externally connecting water supply pipe and stream distributing pipes are connected and assemblied with the water feeding cork cover of each base plate, the water discharging covers are connected to the top of the drainage pipe of the top planting pot, and the lower connecting pipe of the bottom planting pot is connected and assemblied with a return pipe. Positions near the top and bottom of the drainage pipe disposed at the inside rear part of each planting pot are provided with a plurality of water holes. Baffle plates are disposed in the drainage pipes to adapt to shape changes of connecting pipes having height increasing inner pipes or not and a water culture mode or half-water-culture mode of the planting pots can be determined. Accordingly, an integral functional structure of the building planting wall is formed.本發明係提供一種建築物植栽牆結構,主要設具有得併組並固設於建築物牆面之複數基板,基板的前面側設具有縱向嵌槽,俾供複數附設有引流管之植栽盆嵌套組設,並以複數連接管連結組設上、下植栽盆之引流管而固定其上、下間距位置,而在基板內部至少設有一道縱向之引流通道,並於基板頂、底端分別結合組設有出水導蓋及進水塞蓋,使每一基板得構成一獨立之供水導引單元,再配合外接供水管及分流管件接組於各基板的進水塞蓋、各基板的出水導蓋與各最上端植栽盆之引流管頂端相接、以及各最下端植栽盆下端連接管與回流管的接組,乃組構成其完整之循環供水系統,其中每一植栽盆的內側後部所設之引流管的近頂、底端位置分別製設有複數水流孔,且在引流管內部相對於頂端水流孔下緣位置乃設有一阻隔板,使由引流管上端流入的水只能由頂端水流孔注入植栽盆內後,再由底端水流孔導入引流管,配合該連接管之有無增高內管的型式變化,乃得決定其植栽盆的水耕或半水耕種植模式,依此構成本發明之建築物植栽牆的完整功能架構者。(10)‧‧‧基板(11)(12)‧‧‧搭接部(13)(14)‧‧‧嵌槽(15)(16)‧‧‧引流通道(17)‧‧‧栓孔(20)‧‧‧出水導蓋(21)‧‧‧套塞部(22)‧‧‧引流槽(23)‧‧‧導流管(30
