Overview of anchor bolts:
Anchor bolts generally use Q235 steel, which is smooth and round. Rebar (Q345) has high strength, and it is easier to make the thread of the nut without smooth roundness. 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. If the bolt diameter is quite large (such as 45mm) and the buried depth is too deep, the square plate can be welded to the end of the bolt, that is, a large head is enough (but there are certain rejections). The buried depth and the hook are to ensure the friction between the bolt and the foundation, so that the bolt will not be picked up and destroyed again.
Types and uses:
Anchor bolts can be divided into the same anchor bolts, movable anchor bolts, expansion anchor anchor bolts and cement anchor bolts.
1. The same anchor bolts are also called short anchor bolts. They are used together with the foundation grass and used for the same equipment that is not anti-vibration and shock.
2. Movable anchor bolts, also called long anchor bolts, are a kind of muffler anchor bolts, used as heavy machinery and equipment that are offensive to vibration and shock during the same work.
