ANCHOR NAIL FOR GROUND CONSTRUCTION MATERIAL, AND NAIL PRODUCTION METHOD
To provide an anchor nail for a ground construction material which can secure engaging property and large holding force to a ground construction material with low unit weight, which is excellent in placing workability, and which can largely reduce burden on a worker.SOLUTION: An anchor nail includes a nail head portion 12 with a flange diameter of 17 mm or larger at one end side of a nail shaft portion 11 with a diameter D of 6 to 9 mm and a length L of 150 to 300 mm. The other end side of the nail shaft portion 11 forms a pointed end 13. A plurality of protrusions 2 are engraved on at least one of a front face 12a side and a rear face 12b side of the nail head portion 12 in parallel. Many ring-shaped protrusions 4 or screw portions 5 disposed with a constant pitch at least a half part of the pointed end 13 side of the nail shaft portion 11.SELECTED DRAWING: Figure 1
【課題】単重量が小さくとも地面敷設材に対する係止性と大きな地中保持力を確保でき、打込みの作業性に優れ、作業者にかかる負担を大幅に低減し得る地面敷設材用アンカー釘を提供する。【解決手段】径Ｄ：６〜９ｍｍで長さＬ：１５０〜３００ｍｍの釘軸部１１の一端側に、鍔径１７ｍｍ以上の釘頭部１２を有し、釘軸部１１の他端側が尖端１３をなし、釘頭部１２の表面１２ａ側と裏面１２ｂ側の少なくとも一方に複数本の凸条２が平行に刻設され、釘軸部１１の少なくとも尖端１３側半部に、一定ピッチで配置する多数のリング状突起４、もしくはスクリュー部５が設けられてなる。【選択図】図１
