Mechanical connector and precast concrete pile
The invention discloses a mechanical connector and a precast concrete pile. The mechanical connector comprises an inserting rod and a connecting piece. A double-dovetail taper wedge clamping structure is arranged between the plug of the inserting rod and the elastic piece of the connecting piece, and when the elastic piece is in a free state, the diameter of the small-diameter end of the double-dovetail taper clamping groove is smaller than or equal to the diameter of the small-diameter end of the double-dovetail taper clamping table. When the plug is inserted into the connecting piece, the plug and the elastic piece achieve clamping connection of the inserting rod and the connecting piece through the double-dovetail taper wedge clamp. According to the mechanical connector disclosed by the invention, the prefabricated concrete piles are connected through the double-dovetail taper wedge clamp structure, so that the problem that the pulling resistance and shearing resistance of pile connection are reduced due to the fact that axial free space exists between an elastic clamp and a plug of an existing mechanical connector is solved; and the contact surface of the elastic sheet and the plug is multiplied, so that the deformation quantity of the elastic sheet and the plug is greatly reduced when the plug is subjected to the action of drawing force or shearing force, and the pulling resistance and shearing resistance of pile connection are improved.
本发明公开了一种机械接头及预制混凝土桩，其中机械接头包括插杆和连接件；插杆的插头和连接件的弹片之间双燕尾锥度楔卡结构，且在弹片处于自由状态时，双燕尾锥度卡槽的小径端直径小于或等于双燕尾锥度卡台的小径端直径；当插头插入连接件中时，插头和弹片通过双燕尾锥度楔卡实现插杆和连接件的卡接。本发明公开的机械接头由于通过双燕尾锥度楔卡结构进行预制混凝土桩的连接，解决了现有机械接头的弹卡与插头之间存在轴向游离空间，造成桩连接的抗拔和抗剪性能降低的问题，同时，本发明的机械接头，弹片与插头的接触面成倍数增加，从而极大的减小了插头受拉拔力或剪切力作用时，弹片与插头的形变量，提高了桩连接的抗拔和抗剪性能。
