CHAIN LENGTH ADJUSTMENT METAL FITTING
PROBLEM TO BE SOLVED: To provide a length adjustment metal fitting for adjusting an effective length of a construction chain which is used in a construction site.SOLUTION: A chain length adjustment metal fitting is composed of a bolt 1, a bolt head-side engagement member 2 and a tip-side engagement member 3, the bolt head-side engagement member 2 is screw-fit to the bolt 1 in a penetration screw hole 10 which is formed at the bolt head-side engagement member 2, the bolt tip-side engagement member 3 is relatively rotatably and loosely fit to the bolt 1 while being retained at a tip of the bolt 1 so as not come off from the bolt 1, and hooks 6 which can make a chain 15 engaged with the bolt head-side engagement member 2 and the bolt tip-side engagement member 3 are arranged at the bolt head-side engagement member and the bolt tip-side engagement member.SELECTED DRAWING: Figure 5
【課題】建設現場において使用される架設用チエンの有効長さを調節するためのチエン長さ調節金具を提供する。【解決手段】ボルト１、ボルト頭部側係合部材２、及びボルト先端側係合部材３から成り、ボルト頭部側係合部材２は、このボルト頭部側係合部材２が備える貫通ネジ孔１０において前記ボルト１に螺嵌し、ボルト先端側係合部材３は、前記ボルト１の先端部に、当該ボルト１から抜け止めされた状態で当該ボルト１に対して相対回転自在に遊嵌し、ボルト頭部側係合部材２とボルト先端側係合部材３とには、チエン１５を係合させることが出来るフック部６が設けられた構成。【選択図】図５
