PROBLEM TO BE SOLVED: To provide a proper and adequate support of a planting tree which can firmly support the planting tree to reliably prevent collapse thereof, and which is excellent in workability and design, and an installation method of the support.SOLUTION: A support of a planting tree comprises: an underground frame body 3 which surrounds a root pot 2 of a planting tree 1 and is buried in the ground around the root pot and a plurality of support pillars 4 which are installed rising around the planting tree. A lower end part of the support pillar is connected with the underground frame body, and an upper end part of the support pillar is configured to be capable of supporting a trunk of the planting tree. Preferably the underground frame body is formed in a curb shape and the lower end part of the support pillar is rockingly connected thereto by a connecting metal fitting. An installation method of the support of the planting tree is preferably as follows: connecting the lower end part of the support pillar to the underground frame body rockingly in advance arranging the underground frame body at a periphery of a planting hole 6 and spreading the support pillar outward arranging the root pot in the planting hole and then standing the support pillar inside to temporarily support the planting tree and thereafter backfilling the planting hole.COPYRIGHT: (C)2014,JPO&INPIT【課題】植栽樹木を堅固に支持し得てその倒壊を確実に防止可能であり、施工性や意匠的にも優れる有効適切な植栽樹木の支持具およびその設置方法を提供する。【解決手段】植栽樹木1の根鉢2を取り囲んでその周囲の地中に埋設される地中枠体3と、植栽樹木の周囲に立設される複数本の支柱4からなり、支柱の下端部が地中枠体に対して連結され、かつ支柱の上端部が植栽樹木の樹幹を支持可能に構成されている。地中枠体を井桁状としてそれに支柱の下端部を連結金具により揺動自在に連結することが好ましい。地中枠体に対して支柱の下端部を予め揺動可能に連結しておき、地中枠体を植穴6内の外周部に配置するとともに支柱を外側に向けて展開させておき、その状態で根鉢を植穴内に配置した後、支柱を内側に起立せしめて植栽樹木を仮支持し、しかる後に植穴を埋め戻すという手順で施工することが好ましい。【選択図】図1
