Prestressed anchorage device for highway bridge construction

TAN QINGHUA / LUO ZESHUN / LUO ZHIPING

The invention discloses a prestressed anchorage device for highway bridge construction, which comprises an anchorage device shell and a base plate, wherein one end of the anchorage device shell is fixedly connected with an anchor lower cushion plate, the outer wall of one side of the anchor lower cushion plate is connected with an anchor plate, extrusion anchors distributed at equal intervals are arranged on one side of the anchor plate, a pressing plate is arranged at one end of each extrusion anchor, the pressing plate makes contact with one end of the extrusion anchor, one end of the anchorage device shell is communicated with a corrugated pipe, and steel strands distributed at equal intervals are arranged on the inner side of the anchorage device shell and the inner side of the corrugated pipe. According to the invention, a protection shell, a first extrusion rod and a second extrusion rod are arranged to be matched with the action of an extrusion disc, a first clamping plate, a second clamping plate and a magnet, a steel strand can be further fixed, so that after a jack is used for tensioning the steel strand and cutting off the redundant steel strand, with the coordination of the action of an anchor ring, the stability of the steel strand is improved, and the prestressed anchorage device is practical and suitable for being widely popularized and used.

本发明公开了一种公路桥梁施工用预应力锚具，包括锚具外壳和基板，所述锚具外壳一端固定连接有锚下垫板，所述锚下垫板一侧外壁连接有锚板，所述锚板一侧设有等距分布的挤压锚，所述挤压锚一端设有压板，且压板和挤压锚一端相接触，所述锚具外壳一端连通有波纹管，所述锚具外壳和波纹管内侧设有等距分布的钢绞线。本发明通过设置的防护外壳、第一挤压杆和第二挤压杆，配合挤压盘、第一夹紧板、第二夹紧板和磁铁的作用，能够对钢绞线达到进一步的固定效果，从而在使用千斤顶张拉钢绞线并剪除多余的钢绞线后，配合锚环的作用，使得钢绞线的稳定性得到了提升，较为实用，适合广泛推广和使用。
