Pre-tightening mechanical connector clamped by clamping spring, precast concrete pile and connecting method
The invention discloses a pre-tightening mechanical connector clamped by a clamping spring, a precast concrete pile and a connecting method. The connector comprises an insertion rod, wherein the outer wall of the insertion rod is provided with an insertion head with external thread teeth; the large nut is provided with a containing cavity; internal thread teeth are arranged in an insertion cavity of the pre-tightening nut, and the pre-tightening nut comprises a pre-tightening nut thread connecting part and a pre-tightening nut driving part; the threaded connection part of the pre-tightening nut is in threaded connection with the accommodating cavity; the clamping spring is arranged in the internal thread teeth; when the plug is inserted into the clamping spring, the clamping spring retracts and is clamped on the plug, the driving part drives the pre-tightening nut driving part, the pre-tightening nut is made to rotate and move in the axial direction of the large nut, and the plug and the pre-tightening nut are axially locked. According to the pre-tightening mechanical joint disclosed by the invention, a gap between the plug and the pre-tightening nut is effectively eliminated, so that when the mechanical joint is used for connecting precast concrete piles, the joints of the precast concrete piles cannot crack and generate cracks under the action of drawing force, shearing force or bending force.
本发明公开的卡接弹簧卡接的预紧机械接头、预制混凝土桩及连接方法，其中接头包括外壁上设有外螺纹齿牙的插头的插杆；设有容纳腔的大螺母；预紧螺母的插入腔内设有内螺纹齿牙，预紧螺母包括预紧螺母螺纹连接部和预紧螺母驱动部；预紧螺母螺纹连接部与容纳腔螺纹连接；卡接弹簧置于内螺纹齿牙中；在插头插入卡接弹簧中，卡接弹簧收缩卡箍在插头上，驱动部件驱动预紧螺母驱动部，使预紧螺母旋转并沿大螺母轴向运动，将插头与预紧螺母轴向锁紧。本发明公开的预紧机械接头有效的消除了插头与预紧螺母的间隙，使采用该机械接头进行预制混凝土桩连接时，在受到拉拔力、剪切力或弯曲力作用时，预制混凝土桩连接处也不会开裂并产生裂缝。
