Features of Muti-Strands Post-Tension Jack

Maintenance of Muti-Strands Post Tension Jack
(1) the reserved corridor into the structure of the steel wire, in tension requirements of steel beam exposed length than the working length of jack up 200 - 250mm. steel wire must not lose its head with a sheet grinder after cutting, is not a "feather", in order to avoid perforation difficult.
(2) cover the end of the steel wire of the work anchor plate, push it to the anchor plate and fix it at the end of the anchor
(3) installation: Install of anchor clamp clip before the steel ring pay per clip hoop together, and then along the strand will be pushed into the anchor hole, pushed by hand to move.
(4) installing the limiting plate: the spacing plate matches the hole of the anchor plate according to the design of the work anchor plate.

Multi Strands Stressing Hydraulic Jack Operating Notices

1. During the prestressed tensioning construction, the tensioning jack should be calibrated with the oil gauge.
2. The prestressed tensioning equipment and the prestressed misalignment tool should be used according to the jack model in the instruction manual for the misaligned tool.
3. Before the jack is used, the jack, the oil pump, and the oil pressure gauge must be calibrated by the legal measurement technical institution authorized by the competent department in time as required, and the correction coefficient thereof shall be determined. The watch number and the jack number are installed and used together.
4. Before tensioning, the corresponding value of the oil gauge reading of the graded loading and the tensioning force should be calculated according to the correction coefficient formula.
