      Product details

      1. One time embedding method: When pouring concrete, embed the hook bolt. When the tower is controlled by overturning, the hook bolt should be buried in one go.
      2. Reserved hole method: The equipment is in place, the holes are cleaned, the hook bolt are placed in the holes, the equipment is positioned and aligned, and then non shrinkage fine aggregate concrete one level higher than the original foundation is poured and compacted. The distance from the center of the buried hook bolt to the edge of the foundation should not be less than 2d (d is the diameter of the hook bolt), and should not be less than 15mm (when d ≤ 20, it should not be less than 10mm), and should not be less than half of the width of the anchor plate plus 50mm. When the above requirements cannot be met, appropriate measures should be taken to strengthen it. The diameter of the hook bolt used in the structure should not be less than 20mm. When subjected to earthquake action, double nuts should be used for fixation, or other effective measures should be taken to prevent loosening, but the anchorage length of the hook bolt should be increased by 5 days compared to the anchorage length under non earthquake action.
      The installation plan of hook bolt: Treatment of loose hook bolt in the foundation. When tightening the hook bolt, the bolts may be pulled out. At this time, the bolts should be adjusted to their original position first, and the foundation around the bolts should be excavated enough. Then, two U-shaped steel bars should be welded vertically and horizontally on the bolts. Finally, the pit should be cleaned with water and grouted. After the concrete solidifies to the design strength, the deviation of the hook bolt can be tightened. The treatment method for deviation of the hook bolt is roughly the same as that for dead hook bolt, except that the hook bolt can be pulled out for treatment. If the bolt is too long, a section can be cut off on the machine tool and threaded again; If the bolt is too short, it can be extended by hot forging method; If the position does not match, use the bending method to correct it.
      Application industry: Suitable for various equipment fixation, steel structure foundation embedded parts, street lights, traffic signs, pump, boiler installation, heavy equipment embedded fixation, etc.
