[0002] With the rapid development of economic construction, the construction of transportation facilities adapted to it has also achieved rapid development, among which the development of expressways is particularly rapid. In the process of expressway construction, in order to strengthen the structure of the expressway, steel strands are often used in prestressed concrete. Prestressed steel strands are made of high-carbon steel wire rods, which are cold-drawn into steel wires after surface treatment, and then a certain number of steel wires are twisted into strands according to the steel strand structure, and then subjected to a stabilization process to eliminate stress. They are suitable for prestressed concrete engineering and other aspects.

[0003] Prestressed cap beams with high piers and large cantilevers are common. When constructing prestressed cap beams with post-tensioning method, the corrugated pipe needs to be positioned and installed before the cap beam formwork is installed, and the steel strands need to be bundled before the cap beam concrete is poured. For high pier cap beams, the whole bundle of steel strands needs to be placed on the ground and led from the ground to the cap beam. When laying the wires, if the operation is not done properly, it is very easy for the steel strands to pop out and injure people or get entangled, which is not only unsafe but also may cause waste.

[0004] Therefore, in view of the above problems, a device for fixing and paying out steel strands suitable for high pier prestressed cap beams is proposed to solve the above problems. Utility Model Content
