The one end of the connecting pin is threaded to cooperate with the threaded hole of the upper pile end plate; the other end is square and has engaging teeth on both sides, and a joint box is buried under the end plate of the lower pile. The two ends of the joint box A pressure spring is installed between the part and the two pin plates. The end of the connecting pin with the engaging teeth can be inserted between the two pin plates through the square hole on the end plate of the lower post. The teeth on one side mesh with each other.
所述的预应力混凝土管桩快速接头， 其下桩端头板上均匀布置有一个以上的方孔、 接头盒， 上桩端头板上的螺纹孔与方孔相对应， 连接销连接各螺纹孔和接头盒。  In the pre-stressed concrete pipe pile quick joint, more than one square hole and a joint box are evenly arranged on the lower pile end plate, and the threaded holes on the upper pile end plate correspond to the square holes, and the connecting pins connect each thread. Hole and connector box.
在接驳上、 下两段管桩时， 先将连接销带螺紋的一端旋入上桩端头板上的螺紋 孔内， 然后吊起上桩， 使连接销带啮合齿的一端对应下桩端头板上的方孔插入， 一 直插入到连接盒内的两块销板之间， 连接销的啮合齿与销板上的齿在压力弹簧作用 下， 紧密啮合， 使上、 下管桩牢固地接驳在一起。  When connecting the upper and lower pipe piles, first screw the threaded end of the connecting pin into the threaded hole in the end plate of the upper pile, and then lift the upper pile so that the end of the connecting pin with the engaging teeth corresponds to the lower pile. The square hole in the end plate is inserted until it is inserted between the two pin plates in the connection box. The engaging teeth of the connecting pin and the teeth on the pin plate are tightly engaged by the pressure spring to make the upper and lower pipe piles firm. Grounded together.
本发明结构更简单， 成本更低， 而且接驳牢固、 承载力高、 抗弯强度高。 附图说明 图 1是本发明一个实施例的结构示意图； The structure of the invention is simpler, the cost is lower, and the connection is firm, the bearing capacity is high, and the bending strength is high.
