Pre-tightening mechanical connector clamped by elastic pieces, precast concrete pile and connecting method
The invention discloses an elastic sheet clamping pre-tightening mechanical connector, a precast concrete pile and a connecting method. The connector comprises an inserting rod base, an inserting rod connecting part, an inserting head retaining face and an inserting rod of an inserting head. The large nut is provided with a containing cavity; comprising a pre-tightening nut body and a plurality of elastic clamping pieces arranged at one end of the pre-tightening nut body, and an elastic piece clamping face is arranged at the end of each elastic clamping piece. A pre-tightening nut driving part is arranged on the outer wall of the pre-tightening nut body, and when the elastic clamping piece surrounds the insertion rod connecting part and the plug retaining surface is opposite to the elastic piece clamping surface, the driving part drives the pre-tightening nut driving part to enable the pre-tightening nut to rotate and move in the axial direction of the large nut, and the elastic piece clamping surface and the plug retaining surface abut against each other and are locked. According to the pre-tightening mechanical connector clamped by the elastic piece, the axial gap between the plug and the pre-tightening nut is effectively eliminated, so that the joint of a precast concrete pile is not cracked and cracks are not generated when the pre-tightening mechanical connector is subjected to the acting force such as drawing force, shearing force or bending force.
本发明公开了一种弹片卡接的预紧机械接头、预制混凝土桩以及连接方法，其中接头包括具有插杆底座、插杆连接部、插头止退面以及插头的插杆；设有容纳腔的大螺母；包括预紧螺母本体和设置在预紧螺母本体一端的多个弹性卡片的预紧螺母，弹性卡片端部设有弹片卡接面；预紧螺母本体外壁设有预紧螺母驱动部，在弹性卡片环抱在插杆连接部上且插头止退面与弹片卡接面相对时，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，将弹片卡接面与插头止退面抵接并锁紧。本申请公开的弹片卡接的预紧机械接头，有效的消除了插头与预紧螺母之间的轴向间隙，使得在受到拉拔力、剪切力或弯曲力等作用力时预制混凝土桩连接处也不会开裂并产生裂缝。
