Prestressed carbon fiber rib with tapered anchoring ends at two ends and manufacturing method of prestressed carbon fiber rib
The invention relates to a prestressed carbon fiber rib with conical anchoring ends at the two ends and a manufacturing method of the prestressed carbon fiber rib. The prestressed carbon fiber rib is composed of a plurality of carbon fiber filaments. The prestressed carbon fiber rib comprises a middle part, a head-end conical end and a tail-end conical end, the head-end conical end and the tail-end conical end are located at the two ends of the middle part respectively, and each of the head-end conical end and the tail-end conical end is composed of a small cylindrical section, a frustum section and a large cylindrical section which are sequentially connected. And the outer diameter of the small cylindrical section is equal to that of the middle part. The anchoring performance of the anchorage device and the manufacturing difficulty of the anchorage device are actively improved from the type change of the carbon fiber rib, the conical anchoring ends are manufactured at the two ends of the prestressed carbon fiber rib, the anchoring ends are matched with the inner conical anchorage device for use, the anchoring mode can resist deformation of the frustum section through the inner conical anchorage device locking plate, and the anchoring performance is improved.
本发明涉及一种带两端锥型锚固端头预应力碳纤维筋及其制作方法，所述预应力碳纤维筋由多根碳纤维丝组成；所述预应力碳纤维筋包括：中间部分、以及分别位于所述中间部分两端的首端锥形端头和尾端锥形端头，所述首端锥形端头和尾端锥形端头均由依次连接的小圆柱段、锥台段和大圆柱段组成，且所述小圆柱段的外径和所述中间部分的外径相等。本发明主动从碳纤维筋的型式改变来改善锚具锚固性能和锚具制作难度，通过在预应力碳纤维筋的两端制作锥型锚固端头，将锚固端头与内锥型锚具配合使用，该锚固方式可以通过内锥形锚具锁片来抵抗锥台段的变形，提高锚固性能。
