To solve a problem in that, since a suspension metal fitting is suspended in a vertical upright position by a suspending device, it is not easy to connect it to a separate work rod horizontally laid on a ground surface.SOLUTION: Separate work rods 1, each of which is provided with an upper connection part 10 and a lower connection part 11, are joined in a lengthwise direction, thereby forming a work rod R for equipment used in construction work. Suspension metal fitting 15 used for separate works for joining separate work rods 1 in order to form the work rod R comprises: a metal-fitting-side connection part 19 for connecting to either the upper connection part 10 or the lower connection part 11; and a suspension mounting part 18 for mounting an engagement member 21 suspended from a suspension device T. As for the suspension metal fitting 15, according to the position of each separate work rod 1 before the connection, the position of the suspension metal fitting 15 to be suspended from the suspending device T is changed and held by position changing and holding means 30. Thereby, the suspension metal fitting causes the axial direction of the metal-fitting side connection part 19 of the suspension metal fitting 15 to be oriented to the upper connection part 10 or lower connection part 11 of each separate work rod 1.SELECTED DRAWING: Figure 10

    【課題】吊り装置に垂直の起立姿勢で吊り下げられているため、地面に寝かせた横向き姿勢の分割作業ロッドに接続するのが容易でないという課題がある。【解決手段】上側接続部10と下側接続部11とをそれぞれ設けた分割作業ロッド1を、長さ方向に継ぎ足して土木作業に使用される機器の作業ロッドRとし、この作業ロッドRとするために分割作業ロッド1の継ぎ足し分割作業に使用する吊り金具15を、上側接続部10と下側接続部11の何れかに接続する金具側接続部19と吊り装置Tに吊り下げられる係合部材21を取付ける吊用取付部18とを設けて構成し、該吊り金具15は接続する前の分割作業ロッド1の姿勢に合わせて、吊り装置Tに吊り下げる吊り金具15の姿勢を姿勢変更保持手段30により変更させて保持し、もって、吊り金具15の金具側接続部19の軸心方向を分割作業ロッド1の上側接続部10または下側接続部11に対峙させる構成とした吊り金具。【選択図】図10
