Mechanical connection prestressed concrete square pile connector and construction method thereof
The invention discloses a mechanical connection prestressed concrete square pile connector and a construction method thereof, and relates to the technical field of pile foundation construction. Comprising a large nut connected with an upper-section pile body prestressed steel bar and a small nut connected with a lower-section pile body prestressed steel bar. A middle nut is screwed in the small nut; a plurality of blades capable of deforming are evenly arranged on the upper portion of the middle nut. Inserting pieces are inserted in the middles of the multiple lobes. A conical side wall inclined towards the outer wall is arranged at the tail end of the thread of the large nut; after the upper pile body is connected with the lower pile body, the top end of the inserting piece abuts against the prestressed steel bar of the upper pile body, and the lobes are tightly attached to the conical side wall of the large nut. Load is transmitted through friction force, and the problem that due to the construction precision reason during site construction, part of the inserting rods are not completely inserted into the elastic clamp, and consequently a connector fails is solved.
本发明公开了一种机械连接预应力混凝土方桩接头及其施工方法，涉及桩基础施工技术领域。包括与上节桩体预应力钢棒连接的大螺帽和与下节桩体预应力钢棒相连接的小螺帽；小螺帽内螺接有中间螺母；中间螺母上部均匀设置有多个能够发生形变的叶瓣；多个叶瓣的中间插接有插件；大螺帽的螺纹末端设置有向外壁倾斜的锥形侧壁；当上节桩体与下节桩体连接后，插件顶端与上节桩体预应力钢棒抵接，叶瓣与大螺帽的锥形侧壁紧密贴合。本发明通过摩擦力来传递荷载，避免因现场施工时因施工精度原因导致的部分插杆没有完全插入弹卡内部造成的连接接头失效问题。
