PROBLEM TO BE SOLVED: To provide a stretching tool for a leveling string that allows easy installation of a plate material on which an end of the leveling string is fitted.SOLUTION: A stretching tool for a leveling string includes a support tool 5 fitted detachably on a pile, and a fastener 9 for fixing a plate material 101 by sandwiching with the support tool 5. The support tool 5 includes a pile insertion part 13 through which the pile is inserted, a claw member 15 fixed on the pile insertion part 13, and a screw rod-form shaft part 17. The claw member 15 has four triangular claw parts 53 formed by bending four corners of a plate material perpendicularly to the plate surface. The fastener 9 includes a fastening ring 65, a handle part 67, and a cylindrical part 69 into which the shaft part 17 is screwed. The shaft part 17 of the support tool 5 is screwed into the cylindrical part 69 of the fastener 9 while the shaft part 17 of the support tool 5 is inserted in a through-hole 103 of the plate material 101, and the plate material 101 is pressed toward the support tool 5 side by the fastening ring 65. This causes an apex part 53a of the claw part 53 to bite into the plate material 101, thus fixing the plate material 101 by sandwiching the plate material between the claw part 53 and the fastening ring 65.SELECTED DRAWING: Figure 3
【課題】 水糸の一端部が取り付けられる板材の設置が容易な水糸張り具を提供する。【解決手段】 杭に着脱可能に取り付けられる支持具５と、板材１０１を支持具５との間で挟んで固定する留具９とを備える。支持具５は、杭が通される杭挿通部１３と、杭挿通部１３に固定される爪部材１５と、ネジ棒状の軸部１７とを備える。爪部材１５は、板材の四つ角が板面に対して直角に屈曲されて三角形状の爪部５３が４つ形成されている。留具９は、環状の留輪６５と、ハンドル部６７と、軸部１７がねじ込まれる筒状部６９とを備える。板材１０１の貫通穴１０３に支持具５の軸部１７が通された状態で、留具９の筒状部６９に、支持具５の軸部１７をねじ込み、留輪６５により板材１０１を支持具５側に押し込んでいく。これにより、板材１０１に爪部５３の頂点部５３ａが突き刺さり、板材１０１が爪部５３と留輪６５に挟み込まれて固定される。【選択図】 図３
