How to Install Supporting Anchors in the Precision Rolling Thread Steel Plant
Finished threaded steel bars are not used separately and must also be equipped with their supporting anchors. Firstly, screw the completed threaded steel bars into the corrugated pipe, which is 10-20cm shorter than the ends of the steel bars. The model of the corrugated pipe is Φ 40 * 2, Φ 50 * 2 (mm). The function of the corrugated pipe is that when the waterproof layer collapses, micro cracks leak, and drainage facilities are obstructed or fail, the prestressed steel bars may be corroded. Bellows are protective barriers behind prestressed steel in prestressed concrete structures, which can prevent contamination and corrosion of harmful substances on precision rolled threaded steel. They have fatigue resistance and can greatly improve the fatigue resistance of components. Prestressed structures have better durability.

spiral reinforcement
When inserting the precision rolled deformed steel bars into the corrugated pipe, insert the spiral rod into its end and weld an upward small steel pipe to fix the spiral rod and prevent it from sliding. When preparing to insert vertically rolled deformed steel bars into concrete, some construction parties may cover the spiral steel bars on the rolled deformed steel bars. The function of spiral steel bars: When pouring concrete, it can make the contact surface between the spiral steel bars and the entire concrete larger, and can solidify more firmly together. The specification of spiral steel bars is: D × D × n × L=120 × 12 × 6 × 300 (mm). According to the design of the construction company, the specifications of spiral steel bars also vary. Usually, spiral steel bars are made of Q235 hot-rolled ribbed steel bars, as well as 10mm round steel bars. Bottom plate and nut of precision machined screw steel
After fixing the corrugated pipe and spiral steel bar, screw the base plate that matches the steel bar into the end of the spiral steel bar, and then tighten the nut. The function of the substrate and nut is to tighten and secure it. When tensioned, it uses anchoring to tighten the steel bars.
