Precast pile connecting structure and precast pile

ZHONG ZHIQIAN / ZHONG ZHAOHONG

The precast pile connecting structure comprises a connecting box body, the connecting box body comprises an opening and a containing area communicated with the opening, the containing area comprises a conical inner cavity, the small end of the conical inner cavity is close to the opening, and the connecting box body is used for being arranged in a precast pile; the locking sleeve is internally connected to the conical inner cavity and comprises at least two locking petals which are evenly distributed in the circumferential direction of the conical inner cavity, a connecting hole is defined by the locking petals, and a meshing structure is arranged on the hole wall of the connecting hole; the connecting pin comprises a first connecting end, and the first connecting end is connected with the connecting hole through a meshing structure; annular holes are formed in the elastic connecting ring and the locking petals in the circumferential direction, and the elastic connecting ring is connected with the locking petals through the annular holes; the elastic piece is arranged in the conical inner cavity, one end of the elastic piece abuts against the bottom of the containing area, and the other end of the elastic piece abuts against the locking sleeve. The elastic connecting ring tightly hoops the locking petals, so that the connecting stability of the locking sleeve and the connecting pin is enhanced, the operation is convenient, and the connection is stable.

本发明涉及一种预制桩连接结构，包括：连接盒体，连接盒体包括开口以及与其相连通的容置区域，容置区域包括锥形内腔，锥形内腔的小端靠近开口，连接盒体用于设置于预制桩内；锁紧套，锁紧套内接于锥形内腔，包括沿锥形内腔的周向均布的至少两个锁紧瓣，锁紧瓣围成连接孔，连接孔的孔壁设有啮合结构；连接销，连接销包括第一连接端，第一连接端通过啮合结构与连接孔连接；弹性连接圈，锁紧瓣沿周向设有环形孔，弹性连接圈通过环形孔与锁紧瓣连接；弹性件，弹性件设置于锥形内腔内，弹性件的一端与容置区域的底部抵接，弹性件的另一端与锁紧套抵接。弹性连接圈将各锁紧瓣箍紧，增强了锁紧套与连接销的连接稳定性，操作方便，连接稳定。
