Construction and installation of anchor bolts The tensile capacity of anchor bolts is the tensile capacity of the round steel itself, and the size equal to the cross-sectional area multiplied by the allowable stress value is the allowable tensile bearing capacity during design. The anchor bolts generally use Q235 steel, which is round. Rebar (Q345) has high strength, and it is not easy to make the thread of the nut. For smooth round anchor bolts, the buried depth is generally 25 times the diameter, and then a 90-degree hook with a length of about 120mm is made. The buried depth and hook are to ensure the friction between the bolt and the foundation, so that the bolt will not be pulled out and damaged.

Types and Specifications of Anchor Screws Anchor bolts can be divided into fixed anchor bolts, movable anchor bolts, expansion anchor anchor bolts and adhesive anchor bolts. According to different shapes, it is divided into: L-shaped embedded bolts, 9-shaped embedded bolts, U-shaped embedded bolts, welded embedded bolts, and bottom plate embedded bolts. According to the national standard GB/T799-1988 anchor bolt specifications are: M6, M8, M10, M12, M16, M20, M24, M30, M36, M42, M48M. The length range is 80----1500.

The role of anchor bolts. Anchor bolts are mainly used in cement and concrete. They are poured together with the foundation to fix equipment without strong vibration and impact; movable anchor bolts are used for fixing work Heavy machinery and equipment with strong vibration and impact; expansion anchor anchor bolts are often used to fix simple equipment or auxiliary equipment; bonding anchor bolts are a commonly used anchor bolt in recent years, and its methods and requirements are the same as the expansion anchor Foot bolts.
