IRON TOWER APEX PART LEVEL RAISING METHOD
PROBLEM TO BE SOLVED: To provide an iron tower apex part level raising method capable of shortening a power failure time caused by shield angle changing repair work.SOLUTION: An iron tower apex part level raising method comprises a first step of transferring an overhead earth wire 2 to a position of not becoming a hindrance in installation work time of a remodeling installation member 118 being an overhead earth wire installation member for changing a shield angle θof the overhead earth wire 2, a second step of installing four bending work main column materials 11 and web materials (new horizontal materials 12 and new diagonal materials 13) for constituting four surfaces of a truss structure between the bending work main column materials 11 so as to surround an upper-phase bracket installation panel for installing an upper-phase bracket 114, a third step of installing the remodeling installation member 118 on the bending work main column material 11 so as to surround an existing installation member 117 being an existing overhead earth wire installation member installed on the upper-phase bracket installation panel and a fourth step of installing the overhead earth wire 2 in the remodeling installation member 118.SELECTED DRAWING: Figure 1
【課題】遮蔽角変更改修工事に伴う停電時間を短縮することができる鉄塔頂部嵩上げ工法を提供する。【解決手段】架空地線２の遮蔽角θ1を変更するための架空地線取付部材である改造取付部材１１８の取付作業時に支障とならない位置に架空地線２を移線する第１のステップと、上相腕金１１４が取り付けられた上相腕金取付パネルを囲むように、４本の曲げ加工主柱材１１および曲げ加工主柱材１１間にトラス構造の４面を構成する腹材（新設水平材１２および新設斜材１３）を取り付ける第２のステップと、上相腕金取付パネルの上に取り付けられた既設の架空地線取付部材である既設取付部材１１７を囲むように、改造取付部材１１８を曲げ加工主柱材１１の上に取り付ける第３のステップと、架空地線２を改造取付部材１１８に架設する第４のステップとを具備する。【選択図】図１
