Second, the use Prestressing strand use prohibited the use of any form of heat distortion measures in order to reduce the mechanical properties of the steel strand. 2, the use of non-welded joint strength is much lower than the strength of the steel in tension likely to cause broken wires at the solder joint. 3, the cutting of prestressing strand should use a toothless saw (grinding wheel). Welding or gas welding, cutting is easy to make the surface of the steel around the damage. The end portion at the same time causing local overheating, resulting in the decrease of mechanical properties. 4, prestressed steel wire loop fabric reinforcement, the bending radius shall not be less than three times the diameter. Shaftless roll into the packaging of prestressing strand should put the line in the state of stand up from the inner shaft taps the extracted strand into spring, and automatically straight. Tap direction: tap a spring-type spiral direction strands twist to the same, or will be playing of cannabis or out of line. The prestressing strand twist to the left twist, right twist when should be specified in the contract, or directly affect its connection with the anchor. 7, the quality of the prestressed steel wire Duntou The quality of the wire itself has no direct relationship, but the high intensity will be detrimental to wire Duntou quality, so when you choose heading anchor, in order to we stated.
