The invention discloses a prestressed tendon, and relates to the technical field of constructional engineering. Comprising prestressed reinforcements and expanded heads connected to the two ends of the prestressed reinforcements. According to the prestressed tendon disclosed by the invention, the expansion heads are arranged at the end parts of the prestressed reinforcements, so that the anchoring stability of a floor provided with the prestressed tendon can be improved, and when the prestressed reinforcements are released, the shrinkage size of the prestressed reinforcements relative to the floor can be reduced; the situation that the end of the prestressed floor slab is broken due to the fact that the shrinkage size is too large when prestressed steel bars are released can be effectively avoided; and the floor slabs are convenient to connect, and the structural connection integrity is good.
本发明公开了一种预应力筋，涉及建筑工程技术领域。包括预应力钢筋和连接于预应力钢筋两端的扩大头。本发明公开的一种预应力筋通过在预应力钢筋的端部设置扩大头，可增加装有预应力筋的楼板的锚固稳定性，在预应力钢筋放张时，可减少预应力钢筋相对楼板的收缩尺寸，可有效避免预应力楼板因预应力钢筋在放张时收缩尺寸过大导致的端部破碎情况；并且楼板之间连接方便、结构连接整体性好。
