Tooth clamping pre-tightening mechanical connector, precast concrete pile and connecting method
The invention discloses a tooth clamping pre-tightening mechanical connector, a precast concrete pile and a connecting method. The connector comprises an insertion rod with one end being an insertion head, a large nut provided with a containing cavity and a pre-tightening nut, and first teeth are arranged on the outer wall of the insertion head; the pre-tightening nut comprises a pre-tightening nut body and a plurality of elastic clamping pieces arranged in the circumferential direction of the pre-tightening nut body, wherein the inner walls of the elastic clamping pieces are provided with second teeth. The outer wall of the pre-tightening nut body is provided with a pre-tightening nut connecting part and a driving part. The pre-tightening nut connecting part is arranged in the containing cavity and connected with the large nut. The end, provided with the elastic clamping piece, of the pre-tightening nut body is arranged in the containing cavity. After the plug can be inserted into the pre-tightening nut body and the first teeth and the second teeth are clamped, the driving component can drive the pre-tightening nut to rotate and move in the axial direction of the large nut, and therefore the plug and the pre-tightening nut are locked in the axial direction of the large nut. The axial clearance between the plug and the pre-tightening nut is effectively eliminated, the drawing resistance, the shearing resistance or the bending resistance is improved, and no crack is generated at the joint of the precast concrete pile.
本发明公开的齿牙卡接的预紧机械接头、预制混凝土桩以连接方法，其中接头包括，一端为插头的插杆、设有容纳腔的大螺母及预紧螺母，插头外壁设有第一齿牙；预紧螺母包括预紧螺母本体和沿其周向布置的多个内壁设有第二齿牙的弹性卡片，预紧螺母本体外壁设有预紧螺母连接部和驱动部；预紧螺母连接部设于容纳腔内与大螺母连接，预紧螺母本体设有弹性卡片的一端置于容纳腔中；插头能够插入预紧螺母本体中并使第一、第二齿牙卡合后，驱动部件能够驱动预紧螺母旋转并沿大螺母轴向运动，从而将插头与预紧螺母在大螺母轴向方向上锁紧。有效的消除了插头与预紧螺母之间的轴向间隙，提高了抗拉拔力、抗剪切力或抗弯曲力，预制混凝土桩连接处不会产生裂缝。
