Elastic clamping connecting piece, mechanical connector and precast pile connecting structure
The invention discloses an elastic clamping connecting piece, a mechanical connector and a precast pile connecting structure, the elastic clamping connecting piece comprises a connecting piece body and a plurality of elastic pieces arranged at one end of the connecting piece body and arranged in the circumferential direction of the connecting piece body, and the inner wall face of each elastic piece is provided with a first elastic piece clamping face with taper; a certain angle is formed between the line of the two side edges of the first elastic piece clamping face and the generatrix of the first elastic piece clamping face, so that a second elastic piece clamping face is formed in the inner wall face of the elastic piece. According to the elastic clamping connecting piece, the clamping area of the elastic clamping connecting piece and the plug is increased, meanwhile, the direction of the acting force of the two side edges of the clamping face of the elastic piece and the plug clamping face of the plug is changed, then the clamping performance of the inserting rod and the elastic clamping connecting piece is improved, and therefore the anti-pulling performance of precast pile connection is improved.
本发明公开了一种弹卡连接件、机械接头以及预制桩连接结构，其中弹卡连接件包括连接件本体和设置在连接件本体一端并沿所述连接件本体周向布置的多个弹片，弹片的内壁面设有锥度的第一弹片卡固面，第一弹片卡固面的两侧边沿线与第一弹片卡固面的母线成一定角度，使得弹片的内壁面内形成第二弹片卡固面。本发明公开的弹卡连接件不仅增加了弹卡连接件与插头的卡接面积，同时改变了弹片卡固面的两侧边沿与插头的插头卡固面的作用力的方向，进而提高了插杆与弹卡连接件的卡接性能，从而提高了预制桩连接的抗拔性能。
