High Quality Fully Threaded Rod - Hook Bolt – Zonolezer Detail:

1. The use of anchor bolts: 1. The fixed anchor bolts are also called short anchor bolts, which are cast together with the foundation. For fixing equipment without strong vibration and shock.

2. Active anchor bolts, also known as long anchor bolts, are removable anchor bolts. For securing heavy machinery and equipment with strong vibration and shock.

3. Expansion anchor bolts are usually used to fix static simple equipment or auxiliary equipment. The installation of expansion anchor bolts should meet the following requirements: the distance from the center of the bolt to the edge of the foundation is not less than 7 times the diameter of the expansion anchor bolt. The foundation strength of the expansion anchor bolts should not be less than 10MPa. There should be no cracks in the drilled holes. Take care to prevent the drill bit from colliding with the steel pipe and buried pipe in the foundation. The diameter and depth of the drilled hole should match the expansion bolt.

4. Bonding anchor bolts is a kind of anchor bolts commonly used in recent years. The method and requirements are the same as the expansion anchor bolts, but the debris in the hole should be blown clean and not wet. Second, the working principle of the anchor bolts: 1. One-time embedding method: when pouring concrete, the anchor bolts should be embedded first. When the overturning of high-rise buildings is controlled, the anchor bolts should be buried at one time. 2. The method of preparing the hole: put the equipment in place, clean the hole, and insert the anchor bolt into the hole. After the equipment is positioned and calibrated, the non-shrinking fine stone concrete is poured, one level higher than the original foundation. The distance from the center of the ground anchor bolt to the edge of the foundation should not be less than 2d (d is the diameter of the anchor bolt), and should not be less than 15mm (when d≤20, it should not be greater than 15mm and not less than 10mm). If the above requirements cannot be met, it shall not be less than half the width of the anchor plate plus 50mm. Appropriate measures should be taken to strengthen it. The diameter of the anchor bolts used in the structure should not be less than 20mm. When vibration occurs, double nuts should be used to fix it, or other effective anti-loosening measures should be taken, but the anchoring length of the anchor bolts should be 5d longer than the non-anchoring length. The fixing method of the anchor bolts during use is very important, but the reasonable use of the anchor bolts will produce appropriate errors. But it must be within the specified range, of course, there are also precautions when using anchor bolts. Here are four main things to look out for when using anchor bolts. 1. After the anchor bolts, casings and anchor plates enter the factory, they should actively cooperate with the manufacturer, construction unit, quality supervision station, and supervision department to conduct serious acceptance of their quality, quantity and related technical data. Any problems found should be reported to the manufacturer and construction unit immediately and recorded. 2. Anchor bolts, casings and fixing plates that have passed the acceptance inspection shall be properly kept by the material design department. Must be protected from rain, rust and damage and clearly marked. 3. Before installing the anchor bolts, the construction technicians should be carefully familiar with the construction drawings, review drawings and construction plans. Three-level technical explanation for construction personnel. 4. Before the construction of the formwork, please prepare the list of embedded bolt casings and anchor plates according to the requirements of the design drawings. And note the number, size, and burial place (dimensions and heights) and double-check.
