Use galvanized steel wire rope, both ends of the fork with adjustable ear anchorage, one end of the tension side, one end of the fixed side. Ther are three kinds of cable length specifications.
Finished cable delivered to the construction site, the complete on-site installation, tensioning, adjusting claims process.
1) Install the hanging rope:
1-1) Unwreathe: cable transported to the site, the cable channel will be completely unwreathe, pay attention to the protection of cable sheath.
1-2) upper anchor install: the use of mobile cranes or other traction device, the anchor cable hanging from the top node in the top plate, pin penetration.
1-3) lower anchor installation: The end of the tension side of the anchor is adjustable. First sleeve to move to the longest position, easy to install. Put pin roll, the initial tightening sleeve. Complete the cable installation.
1-4) to complete all the above processes in accordance with the installation of cable.
2) The cable tension: stretch the tension cables to the value of design requirements. Tensile force as the project was 100kN and 200kN, requirements on the cable tension is not too high, At the same time, taking into account the limitations of the project, tension equipment used hoist chain and chest-down form. According to tensile force, the construction unit using motor hoister load cable force, the tensile force of chain hoister through the pulley weights to control. Followed by chain hoister load on each cable force, will be straightened and the control cable to the design of cable force. Stretching process, the monitoring should be necessary to avoid the occurrence of large stress changes the structure itself.
3) cable adjustment: the process of the tension steel cable force changes, so it is necessary to adjust the tension of the cable has to ensure that meet the design requirements of steel cable force.
Training rope used to control torque spanner, by setting torque spanner, locking sleeve after the cable tension to tighten. As the special nature of torque spanner, if the cable's force reduction, can be loaded through the spanner tightened, to lock automatically after reach the intended force.
If the cable tension does not change, due to the construction of torque spanner, could not be loaded.
Using torque spanner adjust each rope.
Process should be carried out necessary monitoring to avoid stress changes the structure of the larger.
Transfer process according to the construction site conditions claim, may not need to do.
