Pretensioned Centrifugal Concrete Pile with Steel Strand and Production Method Thereof

摘要

A pretensioned centrifugal concrete pile with steel strands includes a concrete pile body 1 and a reinforcing steel cage. The reinforcing basket has a prestressed main reinforcement, a reinforcing strip 4, and an end plate 2. The prestressed reinforcement is steel strand 3. Each end plate 2 is formed with a plurality of conical holes 21 whose hole diameters gradually increase from the inside toward the outside. A plurality of clips 5 are arranged in the conical hole 21. A tooth 51 is formed on the inner surface of the clip 5, and a plurality of clips 5 are assembled to form a chuck 6 for fixing the steel wire 3. On the outer periphery of the chuck 6, a conical surface 61 corresponding to the conical hole 21 is formed. At the center of the chuck 6, an internal tooth hole 62 is formed. The steel strand 3 passes through the internal tooth hole 62 and is fixed by the internal tooth hole 62. Further provided is a method for manufacturing a pretensioned centrifugal concrete pile with a steel wire.(FIG.
