PROBLEM TO BE SOLVED: To provide a protective sheath that prevents grout material from moving into a gap between an anchor member and the protective sheath with which the anchor member is covered, has sufficient rigidity, and is easy to construct.SOLUTION: A protective sheath 1, with which an anchor member 2 is covered, comprises: a flange-like washer plate contact part 10 on the upper end side in contact with a washer plate part 8 of a bearing pressure plate 3; a bellows part 11 connected to the washer plate contact part's undersurface; and a cylindrical body part 12 connected to the bellows part's lower end. The cylindrical body part 12 is composed of: a spacer projection 13 on the lower end side, having a plurality of rib-like projections on the outer peripheral surface; and an interval holding part 14 that separates the spacer projection 13 from the bellows part 11 and has a diameter shorter than a maximum outer diameter of the spacer projection. The washer plate contact part 10 comprises: a washer plate adhesion part outwardly extending in a flange-like shape from a position connecting with the bellows part 11; and an anchor adhesion part inwardly extending in a flange-like shape. When being fitted into the anchor member 2, the anchor adhesion part can be elastically deformed to adhere to an anchor, thereby preventing grout from moving into a gap between the anchor and the anchor adhesion part.SELECTED DRAWING: Figure 2
【課題】アンカー部材とこれに被せた保護シースとの隙間にグラウト材が入り込むことなく、十分な剛性を備えて施工が容易な保護シースを提供する。【解決手段】アンカー部材２に被せられる保護シース１は、支圧板３の座金板部８に当接する上端側のフランジ状の座金板当接部１０と、その下面に連続する蛇腹部１１と、その下端に連続する円筒体部１２とを備え、円筒体部１２は、外周面に複数のリブ状の突出部を有する下端側のスペーサ突起部１３と、スペーサ突起部１３と蛇腹部１１との間を離間させる、前記スペーサ突起部の最大外径より小径の間隔保持部１４とからなる。前記座金板当接部１０は、蛇腹部１１との接続位置から外側に鍔状に張り出す座金板密着部と内側へ鍔状に張り出すアンカー密着部とを備え、アンカー密着部はアンカー部材２に嵌め入れた際に弾性変形してアンカーに密着可能であり、両者の隙間にグラウトが入り込まない。【選択図】図２
