Locking anchor bolt and cliff abutment construction method by applying locking anchor bolt
The invention relates to a locking anchor bolt and a cliff abutment construction method by applying the locking anchor bolt. The locking anchor bolt comprises a body, a chute is formed in one end of the body, and the other end is fixedly connected to a prefabricated steel bar; and a locking block is slidably connected into the chute, an annular groove is formed in the side wall of the locking block in the circumferential direction, a plurality of locking pieces are hinged into the annular groove, first springs are fixedly connected between the locking pieces and the groove bottom of the annular groove, and a driving piece for driving the locking block to protrude out of a groove opening of the chute and enabling the locking pieces to pop up and be embedded into the hole wall of the throughhole is further arranged in the body. According to the locking anchor bolt and the cliff abutment construction method, the prefabricated steel bars penetrating into the through holes can be locked, the tendency that the prefabricated steel bars move outwards in the through holes is reduced, and the connection tightness between the prefabricated steel bars and the foundation pit is improved.
本发明涉及一种锁定锚栓及应用锁定锚栓的山崖桥台施工方法，锁定锚栓包括本体，本体的一端开设有滑槽，另一端固定连接于预制钢筋上，滑槽内滑移连接有锁定块，锁定块的侧壁上周向开设有环槽，环槽内铰接有若干锁定片，锁定片与环槽的槽底之间固定连接有第一弹簧，本体内还设有驱动锁定块凸出于滑槽槽口、使锁定片弹出并嵌入通孔孔壁中的驱动件。本发明可对穿设至通孔内的预制钢筋进行锁定，减少预制钢筋在通孔内产生向外运动的趋势，提高预制钢筋与基坑之间的连接紧固性。
