摘要:
A pre-tensioned centrifugal concrete pillar includes a concrete body, a steel cage including a plurality of pre-stressed rebars, a plurality of stirrups; and two plates, the rebars are steel strands, a plurality of conical through holes are provided on the plate, and multiple clips are disposed inside each conical through hole, each clip having a toothed inner surface, the multiple clips are spliced together to form a chock assembly for clamping each steel strand, and a peripheral surface of the chock assembly has a conical surface; a clamping hole is formed in the center of the chock assembly, the steel strand passes through a clamping hole and is clamped tightly. A method for manufacturing a pre-tensioned centrifugal concrete pillar is also included.
摘要:
A pre-tensioned centrifugal concrete pillar comprises, a concrete body (1), a steel cage comprising a plurality of pre-stressed rebars, a plurality of stirrups (4); and two plates (2), the rebars are steel strands (3), a plurality of conical through holes (21) are provided on the plate (2), and multiple clips (5) are disposed inside each conical through hole (21), each clip (5) having a toothed inner surface (51), the multiple clips (5) are spliced together to form a chock assembly (6) for clamping each steel strand (3), and a peripheral surface of the chock assembly (6) has a conical surface (61); a clamping hole (62) is formed in the center of the chock assembly (6), the steel strand (3) passes through a clamping hole (62) and is clamped tightly. It is a practical and feasible centrifugal concrete pillar. The present invention also comprises a method for manufacturing a pre-tensioned centrifugal concrete pillar.
