Anchor sealing protection structure for prestress tensioning of maglev rail beam
The invention discloses an anchor sealing protection structure for prestress tensioning of a maglev rail beam, which comprises an anchorage device, locking holes formed in the anchorage device, steelstrands are in one-to-one correspondence with the locking holes and configured to penetrate through the anchorage device, and locking heads arranged on the steel strands. The locking heads and the locking holes are installed in a matched mode, and a protective cover covering the outer surface of the anchorage device is arranged on the anchorage device. The protective cover has the beneficial effects that the protective cover can be used for isolating the anchorage device from concrete, direct contact between the anchorage device and the concrete is avoided, accordingly, the anchorage device isprevented from being corroded by the concrete, the anchorage device is protected, the situation that the service life of the anchorage device is shortened due to corrosion is avoided, and use of a rail is further prevented from being affected.
本发明公开了一种用于磁悬浮轨道梁预应力张拉的封锚保护结构，包括锚具、设置在设置在锚具上的锁紧孔、与锁紧孔一一对应设置且穿过锚具的钢绞线、设置在钢绞线上的锁紧头，所述的锁紧头与锁紧孔配合安装，所述的锚具上设置有包覆锚具外表面的保护罩。本发明的有益效果是：本方案能够利用保护罩隔绝锚具与混凝土，避免锚具与混凝土直接接触，从而防止混凝土对锚具造成腐蚀，有利于保护锚具，避免锚具的使用寿命因受到腐蚀而缩短，进而避免轨道的使用受到影响。
