METHOD FOR REPLACING HORIZONTAL MATERIAL AT BENDING POINT OF STEEL TOWER

To provide a method for replacing a horizontal member at a bending point of a steel tower, which can suitably release the stress of the horizontal member when removing the horizontal member at the bending point by a plat structure.SOLUTION: The method for replacing a horizontal member at a bending point of a steel tower of the present invention is configured so that in a method for replacing a horizontal member at a bending point P of a steel tower 100 in which the stress of a horizontal member 106 is released and the horizontal member 106 is replaced by forming a plat structure Z using an oblique jig 200 and a horizontal jig 300, the plat structure Z is formed above and below the horizontal member 106 arranged horizontally at the bending point P of the tower 100, and at least one horizontal jig 300 of the upper and lower plat structure Z is placed in the vicinity of the horizontal member 106 at the bending point P.SELECTED DRAWING: Figure 1 【課題】プラット結構によって曲げ点の水平材を取り外す際の水平材の応力を好適に開放することが可能な鉄塔の曲げ点の水平材交換方法を提供することを目的とする。【解決手段】本発明の鉄塔の曲げ点の水平材交換方法の構成は、斜め治具２００と水平治具３００を用いてプラット結構Ｚを構成することにより水平材１０６の応力を開放して水平材１０６を交換する鉄塔１００の曲げ点Ｐの水平材交換方法において、鉄塔１００の曲げ点Ｐに水平に配置される水平材１０６の上下にプラット結構Ｚを構成し、上下のプラット結構Ｚの少なくとも一方の水平治具３００を、曲げ点Ｐの水平材１０６の近傍に配置したことを特徴とする。【選択図】図１
