Prestressed anchorage device for road and bridge construction
The invention relates to the technical field of building construction, and discloses a prestressed anchorage device for road and bridge construction. The prestressed anchorage device comprises a corrugated pipe, a working anchor plate, a tool anchor plate and a limiting sliding rod, wherein the right end of the corrugated pipe is fixedly connected with the left side of the working anchor plate, the right side of the working anchor plate is in threaded connection with the left end of the limiting sliding rod, and a first through hole is formed in the right side of the working anchor plate. According to the prestressed anchorage device for road and bridge construction, the limiting sliding rod, a sliding block, a first clamping plate, a second clamping plate, a long rod bolt and the like arearranged, a steel noose is clamped through the first clamping plate and the second clamping plate, the long rod bolt is used for fixing; and due to the fact that the length of the connecting rod is fixed, the distance between every two steel nooses is fixed, the problem that the steel nooses get close to each other is solved, the steel nooses cannot be twisted due to limitation of the first clamping plate and the second clamping plate, and the problem that the steel nooses are broken in advance due to the fact that the steel nooses are stressed unevenly in the pulling process in the steel noose pre-tightening process of an existing prestressed anchorage device is solved.
本发明涉及建筑施工技术领域，且公开了一种路桥施工用预应力锚具，包括波纹管、工作锚板、工具锚板和限位滑杆，所述波纹管的右端与工作锚板的左侧固定连接，所述工作锚板的右侧与限位滑杆的左端螺纹连接，且工作锚板的右侧设有第一穿孔。该路桥施工用预应力锚具，通过设置限位滑杆、滑块、第一夹板、第二夹板和长杆螺栓等，通过第一夹板和第二夹板夹紧钢绞索，并由长杆螺栓进行固定，由于连杆的长度固定，以此每根钢绞索之间的距离被固定，不会发生互相靠近的问题，且由于第一夹板和第二夹板的限制，钢绞索也不会发生扭曲，解决了当前预应力锚具在预紧钢绞索的过程中出现钢绞索在拉拽过程中受力不均，导致钢绞索提前断裂问题。
