The present invention discloses an anchor bolt for waterproofing where water tightness can be maintained by realization of sealing with rotatable formation of a fusion sheet composed integrally with an anchor bolt to allow fusion always after stable adhesion to a waterproof sheet with a fusion sheet attached to a shotcrete layer even when an anchor bolt is obliquely fixed when the anchor bolt is fixed to the shotcrete layer. In the anchor bolt for waterproofing of the present invention, an upper bolt is combined by a pressing member fit in a fixing groove of the shotcrete layer, wedge and bushing, the fusion sheet installed for waterproofing purpose is mold combined with a fixing nut and a connecting ring combined with a lower bolt, a centripetal axis is formed integrally between an upper bolt and a lower bolt of the integrally formed anchor bolt through forging; the fusion sheet is mold formed integrally with a column part having an operation space inside while the fusion sheet realizes a flat sheet form in the upper part of a centripetal axis to be able to rotate around the centripetal axis of the anchor bolt as a center and surrounds the centripetal axis in the lower part; a seal ring fit as an operation space of the fusion sheet to prevent water leakage and a support ring to adhere the seal ring to the centripetal axis are prepared while being secured onto an upper securing groove; a washer having a vertical wall protruding inside to support inside and a lower part of the support ring and having a bump stopped upon fitting in a groove formed at the bottom of a column part of the fusion sheet on a horizontal part is prepared for combination by tightening of the fixing nut. |
