MAIN COLUMN MATERIAL REPLACEMENT METHOD FOR STEEL TOWER
PROBLEM TO BE SOLVED: To provide a main column material replacement method for a steel tower that can make a frame compact and reduce bending moment acting on a main column material.SOLUTION: There is provided a main column material replacement method for a steel tower formed upward to be inclined upward within a main skeleton part 20 while the main skeleton part 20 is composed of a plurality of main column materials 21 such that the respective main column materials 21 have base parts to top parts by a plurality of main column constitution members 21a. A frame 3 is installed over a base 1, a load transmission member 4 is fitted to a main column constitution member 21a above an object main column constitution member 21A to be replaced, and the object main column constitution member 21A to be replaced is replaced after driving force of an actuator 5 is made to act on the load transmission member 4 from the frame 3 to and the load on the object main column constitution member 21A is removed, regions of the frame 3 and load transmission member 4 that the driving force of the actuator 5 acts on being inside the main skeleton part 20.SELECTED DRAWING: Figure 2
【課題】架構の小型化、主柱材に作用する曲げモーメントの低減を図ることのできる鉄塔の主柱材取替工法を提供することを課題としている。【解決手段】複数の主柱材２１により主要骨格部２０が構成され、各主柱材２１は基部から頂部まで複数の主柱構成部材２１ａによって連結形成され、上方に向かって主要骨格部２０内に傾斜すべく形成された鉄塔の主柱材取替工法であり、基礎１の上側に架構３を設置し、また交換対象主柱構成部材２１Ａの上側の主柱構成部材２１ａに荷重伝達部材４を取り付け、架構３から荷重伝達部材４にアクチュエータ５の駆動力を作用させることで、交換対象主柱構成部材２１Ａの荷重を除去してから、交換対象主柱構成部材２１Ａを交換するようになっており、架構３及び荷重伝達部材４におけるアクチュエータ５の駆動力が作用する部位を主要骨格部２０の内側にしていることを特徴とする。【選択図】図２
