1, the cutting of steel strand anchorage should be done with grinding wheel saws, not by arc cutting.
2, when strands are stranded, they should be straightened out and bundled into bundles. The extruded steel strand anchorage or embossed steel strand anchorage for the fixed ends of the steel strands shall be assembled with the bearing plate and the spiral reinforcement in advance.
3, equipment and instruments for prestressing should be regularly maintained and calibrated.
4, before tensioning of steel strand anchorage, concrete strength test report shall be provided. When the compressive strength of concrete meets the design requirements and is no less than 75% of the design strength grade, the prestressing force can be applied.
5, before tensioning of the steel strand anchorage, the bearing plate should be cleaned, and the concrete quality behind the bearing plate should be checked. If the concrete is void, it should be repaired with epoxy mortar before stretching.
6, when the steel wire anchorage is installed, the anchor plate should be correct, the clip should be tightened and the piece position should be uniform: but when the clip is tightened, the clamp should not be overtapping, and the rabbit will break the clip.
