original title: Installation requirements for hot-dip galvanized bolts Hot-dip galvanized bolts are bolts that tighten the upper part of mechanical equipment. It has strong stability and is also called an anchor bolt. expected effect: Firmly connect the cast iron method to the foundation to avoid deviations and collapse during work. The thickness of the protective layer can be used for the installation of the cast iron platform, and the pads of the protective layer are used for heating and backfilling, and then fixed with anchor bolts. Hot-dip galvanized bolts can be divided into fixed anchor bolts, movable anchor bolts, expansion anchor bolts and adhesive anchor bolts. 1. Fixed anchor bolts are also called short anchor bolts. It is poured together with the foundation. Used as industrial equipment, there is no obvious fluctuation and damage. 2. Movable anchor bolts, also known as long anchor bolts, are movable anchor bolts used to fix heavy machinery and equipment. Large fluctuations and damage will occur if they are not moved. 3. Expansion anchor bolts are usually used to fix simple mechanical equipment or auxiliary industrial equipment that do not move or make noise. The installation requirements for expansion anchor bolts are as follows: 1. The distance between important bolts and the edge of the foundation is more than 7 times greater than the straight diameter of the expansion anchor bolt; 2. The compressive strength of the installation foundation of the expansion anchor bolt should not be less than 10 MPa; 3. There should be no gap in the drilling position, and care should be taken to avoid the impact of twist drills, rigid steel bars and steel wire pipes on the foundation. 4. Bonded anchor bolts are a type of anchor bolts that have been widely used in recent years. Their methods and requirements are the same as expansion anchor bolts. However, please be careful to blow out the dirt in the holes when bonding. Wet and cold are not allowed. Anchor bolts are different from ordinary bolts. Anchor bolts are placed above the ground or inside the foundation to connect the ground, foundation and mechanical equipment. But general bolt basic expertise stops general contact. Since hot-dip galvanized bolt bolts connect mechanical equipment to the ground and foundation, hot-dip galvanized bolts are usually laid in the soil or concrete of the foundation, and the other end has an inch thread, which is fixed with a screw pad. Need to repair machinery or industrial equipment. In addition to the differences in application areas, it is also an important difference that the ends of bolts are produced and machined into various product designs that can withstand torque.
