When the mechanical anchor is used, the substrate to be used is usually drilled, and the anchoring effect is formed by tangential locking of the mechanical anchor and the reaming wall of the hole in the bottom. It can be seen that how to drill, the depth of the hole and the size of the hole are all important for the mechanical anchor to play its true reinforcement.
So how can we determine the drilling depth of the mechanical anchor? Here we need to divide according to different scenarios and treat them differently. Since the construction environment is not very singular, there are many variables that are constantly changing, such as the concrete markings that need to be drilled are different. Whether the concrete substrate is very intact and there is no cracking. The margins and spacing of the installation are so on. So today we focus on the depth of the penetration of a single mechanical anchor in the case of large spans and margins in cracked c20/25 concrete.
There are many different types of mechanical anchors, each of which corresponds to a different screw length. It can be seen from the following figure that different types of mechanical anchors have different drilling depths.
The mechanical anchor bolts produced by Nanjing Mankate are complete in type. When using the special reaming drills, it can better ensure the mechanical anchoring effect of the mechanical anchors and achieve the reinforcement effect. Welcome to inquire about Nanjing Mankate mechanical anchor.
