ANCHORAGE STRUCTURE FOR HEAD OF TENDON
To provide an anchorage structure for a head of a tendon allowing water from the underground to be prevented, visual check on a state of anchorage structural material to be performed, and its protruded length to be shortened.SOLUTION: An anchorage structure is provided with: an anchor head 1 which has a thread groove formed on its periphery and an upper end of which holds a part of a tendon 8 though a wedge 2; a nut 3 fitted in the periphery of the anchor head 1 and mating with the thread groove; a retainer 5 placed between the nut 3 and a bearing pressure plate 4; a cut-off member 6 accommodated in an accommodation space surrounded with the bearing pressure plate 4 and the retainer 5 and in communication with a through hole 41 arranged in the bearing pressure plate 4, and being taller in height than the accommodation space and having elasticity; and a head cap 7 covering the accommodation space at positions of the anchor head 1, a tip of the tendon 8, the nut 3, and the retainer 5 to closely contact the bearing pressure plate 4 in a watertight state, wherein the tendon 8 is passed through an insertion hole penetrating the retainer 5 and the cut-off member 6, and deformation of the cut-off member 6 is regulated in a direction away from the bearing pressure plate 4 and in a cross-sectional direction to be compressed.SELECTED DRAWING: Figure 1
【課題】地中からの水の侵入を防止でき、定着構造部材の状態を視認により点検することができ、突出長を小さく抑えることができる、テンドンの頭部定着構造を提供する。【解決手段】外周にネジ溝が形成され、上端でくさび２を介しテンドン８の一部を保持するアンカーヘッド１と、アンカーヘッド１の外周に嵌装されネジ溝に螺合するナット３と、ナット３と支圧板４の間に配置される押え具５と、支圧板４と押え具５で囲われ支圧板４に設けられた貫通孔４１に連通する収容空間に収容され、高さが収容空間の高さよりも大きく弾力性を有する止水部材６と、アンカーヘッド１、テンドン８の先端部、ナット３、及び押え具５において収容空間を囲う部位を覆い、支圧板４に水密状態で密着するヘッドキャップ７を備え、テンドン８は、押え具５と止水部材６を貫通する挿通孔に通され、止水部材６は、支圧板４から離れる方向及び横断面方向への変形が規制され、圧縮される。【選択図】図１
