4. Product Structure
PSB830 precision threaded steel bar anchor is made of high strength steel and processed with continuous threaded ribs. Threaded steel bars allow nuts, plates, couplers and other anchoring accessories to be connected along the bar at will, which is convenient for tightening, anchoring or extending on site.
PSB830 has better tensile properties and bearing capacity than ordinary threaded bars. Therefore, it is more suitable for engineering projects that need stable anchorage and strong pullout resistance.
5. Application fields
PSB830 anti-floating precision threaded steel bar anchor is widely used in foundation reinforcement, basement anchorage, bridge anchorage, tunnel rock anchorage, hydropower and water conservancy, mining engineering slope protection, foundation pit support and anchorage:
Foundation anti-floating;
Basement anchorage and underground structure;
Bridge anchorage and reinforcement;
Tunnel support and rock anchorage;
Hydropower, water conservancy and other projects;
Mining engineering, slope protection;
Foundation pit support and anchorage.
6. Standards
Production and quality inspection can be performed according to different project requirements and standards, such as:
GB / T 20065-2006 Steel Bars for Prestressed Concrete
JG / T 163-2013 Hot Rolled Ribbed Steel Bars for Reinforced Concrete
JGJ / T 152-2014 Technical Specification for Mechanical Splicing of Steel Reinforcing Bars
YB / T 5 148-2016 Threaded Steel Bars for Prestressed Concrete
