Anchorage device for subsequent holing protection of prestressed floor slab and anchoring method of anchorage device
The invention discloses an anchorage device for subsequent holing protection of a prestressed floor slab and an anchoring method of the anchorage device, and relates to the technical field of constructional engineering.The anchorage device comprises an open anchor ring, a wedge block and a plurality of clamping pieces, a conical eccentric hole is formed in the anchor ring in the axial direction of the anchor ring in a penetrating mode, and the wedge block is correspondingly inserted into the opening and slidably connected with the anchor ring; the plurality of clamping pieces are used for wrapping a reinforcing steel bar or a steel strand together and wedged into the conical eccentric hole; at least two auxiliary clamping plates are arranged on the inner wall of the conical eccentric hole in the end, close to the small hole assembling face, of the anchor ring and distributed in the circumferential direction of the conical eccentric hole at intervals, and a driving assembly is arranged in the side wall, corresponding to the auxiliary clamping plates, of the anchor ring. The wedge block drives the auxiliary clamping plates to move in the direction close to or away from the axis of the conical eccentric hole through the driving assembly, and the at least two auxiliary clamping plates clamp the reinforcing steel bar or the steel strand at the same time so that the anchorage device can be integrally fixed to the reinforcing steel bar or the steel strand. The anchor device has the effect of improving the stability of the anchor device.
本申请公开了一种用于预应力楼板后续开洞保护的锚具及其锚固方法，涉及建筑工程的技术领域，包括开口的锚环、楔块和多个夹片，锚环内部沿自身轴向贯穿开设有锥形偏心孔，楔块对应插设于开口内并与锚环滑动连接，多个夹片用于共同包裹钢筋或钢绞线并楔入锥形偏心孔内；锚环于靠近小孔装配面一端的锥形偏心孔内壁设置有辅助夹板，辅助夹板至少设置有两个，且沿锥形偏心孔周向间隔分布，锚环对应辅助夹板的侧壁内设置有驱动组件，当楔块楔入开口内时，楔块通过驱动组件驱使辅助夹板朝靠近或远离锥形偏心孔轴线的方向运动，至少两个辅助夹板同时夹紧钢筋或钢绞线，以使锚具整体固定于钢筋或钢绞线。本申请具有提高锚具稳定性的效果。
