CROSSARM REINFORCEMENT METAL FITTING, CROSSARM REINFORCEMENT METAL FITTING SET, AND REINFORCEMENT METAL FITTING
To provide a crossarm reinforcement metal fitting which can be attached to a crossarm easily attached to an electric pole, and can improve breaking strength of the crossarm attached to the electric pole, without performing an operation for loosening a bolt that fixes the existing crossarm.SOLUTION: A crossarm reinforcement metal fitting W has a main body part 5 extended to a long direction of a crossarm 2. The main body part 5 comprises: an almost plate-like base surface part 20 in which two long side parts 20a and 20b which are extended to the long direction and are formed in parallel are formed; and a back surface pressing part 25 that is projected toward a lower direction at a position of a neighbor on the one long side part 20a side of an intermediate part in the long direction of the base surface part 20. In both end parts on the other long side part 20b side of the base surface part 20, a reinforcement part 23 extended to the lower direction at an almost right angle is provided, and a hole 21 for a bolt for being fastened to the crossarm 2 is provided in the base surface part 20.SELECTED DRAWING: Figure 9
【課題】既設の腕金を固定しているボルトを緩める作業を行う事無く、簡単に電柱に取り付けられた腕金に取り付けることが出来ると共に、電柱に取り付けられた腕金の破壊強度を向上させることができる腕金補強金具を提供する。【解決手段】腕金補強金具Ｗであって、腕金２の長手方向に伸びる本体部５を有し、本体部５は、長手方向に延設され且つ平行をなす２つの長辺部２０ａ、２０ｂが形成された略板状の基面部２０と、基面部２０の長手方向の中間部の一方の長辺部２０ａ側近傍の位置で下方に向けて突出している背面押さえ部２５とを備え、基面部２０の他方の長辺部２０ｂ側の両端部には、それぞれ、下方に向けて略直角に延設された補強部２３が設けられ、基面部２０には、腕金２に固着するためのボルト用穴２１が設けられている。【選択図】図９
