Zigzag pipe pile quick connector
The invention discloses a zigzag pipe pile quick connector, and relates to engineering pile connection. The zigzag pipe pile quick connector aims to solve the problems of insufficient connection strength, weak radial tensile force resistance and high pre-embedding precision requirement. According to the technical scheme, the zigzag pipe pile quick connector is characterized by comprising an upperembedded part and a lower embedded part, wherein the upper embedded part and the lower embedded part are of an open-ended structure, a bushing is fixed on the upper embedded part in a threaded mode, aconical surface is arranged on the inner wall of the bushing, a plurality of meshing petals are arranged in the bushing, the meshing petals are connected when at the lowest end of the bushing to forma conical frustum shape, a plurality of tooth grooves are formed in the inner wall of each meshing petal at equal intervals along the length direction, an insert matched with the meshing petals in aninserting mode is fixed to the lower embedded part in a threaded mode, and the insert is provided with a plurality of cogs embedded with the tooth grooves. According to the zigzag pipe pile quick connector, the pouring fixing strength of the connector and concrete pipe piles is improved, the connecting strength of adjacent concrete piles is ensured, the radial tensile force resistance is improved, and the precision requirement for the embedded depth is reduced.
本发明公开了一种锯齿形管桩快速连接件，涉及工程桩连接，旨在解决连接强度不足、抗径向拉力较弱以及预埋精度要求过高的问题，其技术方案要点是：一种锯齿形管桩快速连接件，包括上预埋件和下预埋件，上预埋件和下预埋件均呈一端开口结构，上预埋件螺纹固定有衬套，衬套的内壁设置有圆锥面，衬套内设置有若干咬合瓣，若干咬合瓣处于衬套最低端时连接形成圆锥台形，咬合瓣的内壁沿长度方向等间距设置有多个齿槽，下预埋件螺纹固定有与咬合瓣插接配合的插件，插件设置有多个与齿槽嵌合的嵌齿。本发明的一种锯齿形管桩快速连接件，提高与混凝土管桩的浇筑固定强度，确保相邻混凝土桩的连接强度，提高抗径向拉力，降低预埋深度的精度要求。
