Pre-tightening mechanical connector with middle sleeve, precast concrete pile and connecting method
The invention discloses a pre-tightening mechanical connector with a middle sleeve, a precast concrete pile and a connecting method. The connector comprises an inserting rod provided with an inserting head; the large nut is provided with a containing cavity; the clamping mechanism is arranged in the accommodating cavity; the pre-tightening nut is in threaded connection with the large nut; the middle sleeve is sleeved on the pre-tightening nut and located on the outer side of the large nut, a transmission structure is arranged on the middle sleeve, and the transmission structure is used for driving the middle sleeve to rotate by the driving component when the plug is clamped with the clamping mechanism, so as to drive the pre-tightening nut to rotate and move along the axial direction of the large nut, so that the plug and the clamping mechanism are locked in the axial direction of the large nut. 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.
本发明公开了一种具有中间套的预紧机械接头、预制混凝土桩以及连接方法，其中接头包括，设有插头的插杆；设有容纳腔的大螺母；设于容纳腔内的卡接机构；与大螺母螺纹连接的预紧螺母；套在预紧螺母位于大螺母外侧的中间套，中间套上设有传动结构，传动结构用于在插头与卡接机构卡接时，由驱动部件驱动中间套旋转，进而驱动预紧螺母旋转并沿大螺母轴向运动，从而将插头与卡接机构在大螺母轴向方向上锁紧。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，使采用本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。
