HOLE-IN ANCHOR INSTRUMENT, HOLE-IN ANCHOR AND HOLE-IN ANCHOR FITTING STRUCTURE
PROBLEM TO BE SOLVED: To provide a hole-in anchor instrument which can prevent pull-out of a body from a concrete skeleton and loosening of a bolt, can change a bolt length after a hole-in anchor has been placed, and is excellent in flexibility of construction.SOLUTION: A hole-in anchor instrument 1 has a cylindrical body 3 having an expanding piece 32 in a front portion, an approximately truncated cone shaped cone 4 that has a female screw 42 formed therein and at least a rear end of which is placed inside of the body 3, and a fitting bolt 5 that is inserted to the body 3 and where a male screw 51 is threadingly fitted to the female screw 42 of the cone 4, where a partially projecting plate spring 44 is provided on a female screw hole 41 in the vicinity of a tip of the female screw 42 of the cone 4, and the plate spring 44 is hooked in the vicinity of a tip of the male screw 51 of the fitting bolt 5.SELECTED DRAWING: Figure 3
【課題】コンクリート躯体からの本体の抜け出しやボルトの緩みを防止することができると共に、あと施工アンカー打設後にボルト長の変更をすることが可能で施工の柔軟性に優れるあと施工アンカー器具を提供する。【解決手段】前部に拡開片３２を有する筒状の本体３と、内部に雌ねじ４２が形成され、少なくとも後端部が本体３に内装される略截頭錐形のコーン４と、本体３に挿通されてコーン４の雌ねじ４２に雄ねじ５１が螺合される取付ボルト５を備え、コーン４の雌ねじ４２の先端近傍に雌ねじ穴４１に部分的に突出する板ばね４４が設けられ、板ばね４４が取付ボルト５の雄ねじ５１の先端近傍に掛止されるあと施工アンカー器具１。【選択図】図３
