Introduction to the Use and Working Principle of Anchor Bolts by Anchor Bolt Manufacturers

Introduction to the Use and Working Principle of Anchor Bolts by Anchor Bolt Manufacturers1. Fixed anchor bolts, also known as short anchor bolts, are inverted together with the foundation. Used for fixing equipment, without strong vibration and impact.2. The movable anchor bolt, also known as the long anchor bolt, is a detachable anchor bolt. Used to fix heavy machinery and equipment, with strong vibration and impact.3. Expansion anchor bolts are usually used to secure simple stationary 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 should not be less than 7 times the diameter of the expansion anchor bolt. The foundation strength of expansion anchor bolts shall not be less than 10MPa. 

There should be no cracks during the drilling process. Be careful to prevent the drill bit from colliding with the steel pipes and buried pipes on the foundation. The diameter and depth of the opening should match the expansion anchor.4. Anchor bolts are commonly used in recent years. The method and requirements are the same as those for expansion anchor bolts, but the debris inside the hole should be blown clean and not wetted.Working principle of anchor bolts:1. One time burial method: When pouring concrete, anchor bolts should be buried first. When controlling the overturning of high-rise buildings, the anchor bolts should be buried in one go.2. Method of preparing holes: Place the equipment in place, clean the holes, and insert the anchor bolts into the holes. After positioning and correcting the equipment, it is poured together with non shrinkage fine aggregate concrete, which is one level higher than the original foundation. The distance from the center to the edge of the foundation for one-time buried anchor bolts shall not be less than 2d (where d is the diameter of the anchor bolt) and shall not be less than 15mm (when d ≤ 20, it shall not be greater than 15mm and shall not be less than 10mm). If the above requirements cannot be met, it should not be less than half the width of the anchor plate plus 50mm. 

Appropriate measures should be taken to strengthen. The diameter of the anchor bolts used in the structure shall not be less than 20 millimeters. When vibrating, double nuts should be used for fixation or other effective measures should be taken to prevent loosening, but the anchorage length of the anchor bolt should be 5d longer than that of the non anchorage.The fixing method of anchor bolts is very important during use, but reasonable use of anchor bolts will result in appropriate errors. But it must be within the specified range, and of course, attention should also be paid when using anchor bolts. Here are four key points to pay attention to when using anchor bolts.1. After the anchor bolts, sleeves, and anchor plates enter the factory, they should actively cooperate with the manufacturer, construction unit, quality supervision station, and supervision department to carefully inspect and accept the quality, quantity, and relevant technical data. 

If there are any problems, they should be reported to the manufacturer and construction unit immediately and recorded.The accepted foundation bolts, sleeves, and fixing plates should be properly stored by the material design department. It is necessary to prevent rain, rust, and loss, and to have clear markings.Before installing anchor bolts, construction technicians should carefully familiarize themselves with construction drawings, drawing reviews, and construction plans. Provide three-level technical explanations to construction personnel.Before constructing the template, please prepare a list of embedded bolt sleeves and anchor plates according to the requirements of the design drawings. Please indicate the quantity, specifications, and location (size and height), and carefully inspect them.
