Anchor bolts are a kind of mechanical parts. The anchor bolts used in different specifications of concrete are also different. The main function is to fix related objects. So what are the standard classification and raw materials of anchor bolts?
Standard classification of anchor bolts
Anchor bolts can be divided into fixed anchor bolts, movable anchor bolts, expansion anchor anchor bolts and bonded anchor bolts. According to different shapes, it can be divided into: L-shaped embedded bolts, 9-shaped embedded bolts, U-shaped embedded bolts, welded embedded bolts, and bottom plate embedded bolts.
Specification for anchor bolts
Pour the anchor bolts and the ground with cement and other objects together to fix the equipment without violent vibration and impact. The movable foot is a kind of detachable foot bolt, which can fix large-scale machinery and equipment with intense vibration and impact.
Anchor bolt specification material
The general anchor bolts are made of Q235 steel. Although it is not the strongest, it is more convenient to make the shape and details of the anchor bolts. Q235 steel is a kind of carbon structural steel, this kind of steel can be used directly without heat treatment under normal circumstances. It is a very convenient steel. Q345 rebar. It is a low-alloy steel, which has a greater hardness. And it has outstanding mechanical properties, low temperature, plasticity and weldability. Can be widely used in various occupations.
Specification for anchor bolts
Low-alloy high-strength structural steel (16Mn), its carbon content and gold content are relatively small. The main data are: manganese data, silicon data, vanadium data, etc. Because of its low alloy content, the weldability is better than that of ordinary alloy materials, so there is no need to preheat in advance for welding. 40Cr steel. Compared with the above steels, the anchor bolts made with it have the greatest strength. And after some special treatments, it has good generalized mechanical properties, good resistance under low temperature conditions, and excellent sensitivity to notches.
