Supplementary tensioning equipment for prestressed concrete structure
The embodiment of the invention provides supplementary tensioning equipment for a prestressed concrete structure. The supplementary tensioning equipment comprises a cylinder body, a sliding plate, a driving mechanism and a locking mechanism. An accommodating cavity is formed in the cylinder body. The sliding plate is located in the accommodating cavity, prestressed tendons of the prestressed concrete structure penetrate through the cylinder body and the sliding plate, and the prestressed tendons are connected with the sliding plate. The driving mechanism can drive the sliding plate to be awayfrom a concrete body of the prestressed concrete structure so as to tension the prestressed tendons. The locking mechanism can lock the sliding plate. According to the supplementary tensioning equipment provided by the embodiment of the invention, after the prestress loss is generated, the prestress loss is compensated through supplementary tensioning of the prestressed tendons so that the problemof the prestress loss can be better solved.
本申请实施例提供一种用于预应力混凝土结构的补张拉设备，补张拉设备包括缸体、滑动板、驱动机构以及锁定机构。缸体形成有容纳腔。滑动板位于容纳腔内，预应力混凝土结构的预应力筋穿过缸体和滑动板，预应力筋与滑动板连接。驱动机构能够驱动滑动板远离预应力混凝土结构的混凝土体，以张拉预应力筋。锁定机构能够锁定滑动板。本申请实施例提供的补张拉设备，在预应力损失产生后，通过补张拉预应力筋以补偿预应力损失，从而能够更好地解决预应力损失问题。
