SUSPENSION MATERIAL REPLACEMENT DEVICE AND SUSPENSION MATERIAL REPLACEMENT METHOD
To provide a suspension material replacement device and a suspension material replacement method using the same, which can safely and reliably replace a suspension material regardless of who performs the operation, even when a section of the length of the suspension material is short.SOLUTION: A suspension material replacement device for replacing a suspension material (existing suspension material ES) attached to a main rope MC and supporting a structure (upper chord material UM) by suspension, comprises: a main rope hooking member (temporary suspension metal fitting 2) hooked on the main rope MC; a structure lifting member (lifting metal fitting 3) fixed to lift a structure (upper chord material UM); temporary suspension means 5 for connecting the main rope hooking member and the structure lifting member so as to be adjustable in length; a hydraulic jack 6 interposed in the temporary suspension means 5 and capable of being pushed and pulled; and a tension meter 7 connected to one end of the hydraulic jack 6 for measuring the tensile force.SELECTED DRAWING: Figure 2
【課題】誰が行っても、また吊材の長さが短い箇所があっても安全かつ確実に吊材の取替を行うことができる吊材取替装置及びそれを用いた吊材取替工法を提供する。【解決手段】主索ＭＣに装着されて構造物（上弦材ＵＭ）を吊下げ支持する吊材（既設吊材ＥＳ）を取り替える吊材取替装置であって、主索ＭＣに掛け止められる主索掛止部材（仮吊金具２）と、構造物（上弦材ＵＭ）を吊り上げるために固定される構造物吊上部材（吊上金具３）と、前記主索掛止部材と前記構造物吊上部材とを長さ調整可能に接続する仮吊手段５と、を備えるとともに、仮吊手段５に介装されて押し引き可能な油圧ジャッキ６と、油圧ジャッキ６の一端に接続されて張力を計測する張力計７と、を備える。【選択図】図２
