To provide an assisting tool for marking which enables one worker to easily perform marking work on an irregular face not allowing sticking of a pin of a fixing piece, a stepped face or a vertical face, when performing the marking work with a marking tool.SOLUTION: In an assisting tool 2 for marking, the center of a rectangular plate member 11 is mountain-folded, a lower part of a tip end of a member 13 or 14 branched into two by being mountain-folded is formed thin or in parallel to a mountain-folded part 12, and grooves 23, 24, 25 and 26, 27, 28 allowing passing of ink threads to cross orthogonally undersurfaces 17 and 21 of the tip ends are provided. The undersurfaces 17 and 21 of the narrow and separated parallel two faces serve as contact faces, preventing slipping even on an irregular face, and allowing stable contact at a stepped face by being branched into two. By placing a fixing piece on an inner face 18 of the member 13, and by passing the ink thread through the grooves 23, 24 or 25, the assisting tool 2 for marking serves as the fixing piece, allowing marking by one worker.SELECTED DRAWING: Figure 3
【課題】墨出し器で墨出し作業をする場合においてカルコの針が刺さらない面でしかも凹凸の有る面、段差のある面又は垂直面の墨出し作業が一人で容易にできる。【解決手段】 本発明の墨出し補助具２は、長方形の板状部材１１の中央を山折りし、この山折りして二股に分かれたそれぞれの部材１３又は１４の先端の下部を細く又山折り部１２に平行に形成し、これらの先端の下面17及び２１に墨糸が直交し横切るように通過する溝２３、２４、２５及び２６、２７、２８を設けた墨出し補助具としたので、幅の狭い分離した平行な２面の先端の下面17及び21が接面部となり、凹凸のある面においても滑り難く又二股に分かれているので段差のある面においても安定して接面でき、カルコを部材１３の内面１８に置き、墨糸を前記溝２３、２４若しくは２５に通すことで前記墨出し補助具２がカルコの代わりになり一人で墨出し作業が容易にできる。【選択図】図３
