MANUFACTURE OF ANCHOR

PROBLEM TO BE SOLVED: To solve a problem in which, in burying of an anchor using a conventional casing, an anchor that has a structure in which a blade part is installed so as to go one round around an outer peripheral wall of a cylindrical anchor is used, so the anchor itself is long and large, and there are difficulties such as transportation, storage, materials and costs of the anchor.SOLUTION: In an anchor of this invention, which is an anchor that is configured to be installed on the lower part of a blade, and in which surplus materials from manufacture of the blade is used efficiently, the blade is installed on the lower end of a cylindrical body, and a tip claw that is installed on the lower part of the blade is manufactured using the surplus materials.SELECTED DRAWING: Figure 1 【課題】 従来のケーシングによるアンカーの埋設は、アンカーの円筒体の外周壁に羽根の部分を１周して設置する構造のアンカーを使用しておりました。そのため、アンカー自体が長く大きく、アンカーの運送、格納、材料、費用、等が問題になっております。【解決手段】 本発明のアンカーは、円筒体の下端に羽根を設置し、羽根の製作で出た残材を、羽根の下部に設置する先端爪として製作し、羽根の下部に設置する構造のアンカーで、残材を無駄なく使用するアンカーである。【選択図】図１
