COUPLING METAL FITTING FOR COME-ALONGLESS METHOD, AND COME-ALONGLESS METHOD USING THE SAME

To provide a coupling metal fitting for a come-alongless method and a come-alongless method using the same in which the coupling metal fitting (link) of an improved type having wire tensioning (slackness adjustment) work and double-protection functions is used for an insulator device so that contributions can be made to workability improvement which is obtained by significant reduction in worker's manpower and safety improvement which is obtained by significant reduction of a risk of falling of a worker, and a tool and the like.SOLUTION: Provided are a coupling metal fitting for a come-alongless method, and a come-alongless method using the same. The coupling metal fitting for a come-alongless method is for use in wire tensioning work of an electric wire that is disposed between steel towers, and in double-protecting work that is performed during the wire tensioning, and the coupling metal fitting is connected between a clevis or clamp disposed on the electric wire side and a vernier fitting or clevis disposed on a steel tower side, and the coupling metal fitting includes a protection hole for the double-protection work provided at least at one point other than a hole for tensioning the wire to be coupled, By the come-alongless method, the wire tensioning work and the double-protection work during the wire tensioning work are performed at the same time.SELECTED DRAWING: Figure 1 【課題】がいし装置に緊線（弛度調整）作業及び二重防護の機能を持ち合わせた改良型の連結金具（リンク）を用いることにより、作業員の大幅な労力低減による施工性向上、及び作業員並びに工具類の落下リスクの大幅な低減による安全性向上に貢献することができるカマレス工法用連結金具及びこれを用いたカマレス工法の提供。【解決手段】鉄塔間に架設される電線の緊線作業、及び該緊線時の二重防護作業に使用するカマレス工法用連結金具であって、前記連結金具は、前記電線側にあるクレビス又はクランプと鉄塔側にあるバーニヤ金具又はクレビスの間に連結され、かつこの連結金具は、連結される緊線用孔以外の少なくとも１か所以上に二重防護作業のための防護用孔が設けられたことを特徴とする、カマレス工法用連結金具、及びこれを用いて緊線作業及び緊線作業中の二重防護を同時におこなう、カマレス工法。【選択図】 図１
