The role of the J anchor bolt is obvious, it is very important, let's understand the specific situation of the J anchor bolt. First of all, let's understand the production materials of anchor bolts, generally using q235, q345 to make anchor bolts. The strength of Q345(that is, rebar) is relatively large, so the thread of the nut is not simple to use up the circle. If the optical round J anchor bolt is buried, the depth of the buried bolt is about 25 times the diameter of the bolt, and of course, the final need to make a 90-degree Angle about 12 cm curved hook. It is possible to encounter the diameter of the bolt is too large (such as 45 mm), so the depth of the embedment will be relatively large, at this time, it is necessary to weld a square plate on the top of the anchor bolt (that is, to make a large head, but this is also in line with the regulations). Why do the installation of anchor screws need to have the requirements of buried depth and Angle? All this is to ensure the friction between the J anchor bolt and the foundation, to prevent the J anchor bolt from being pulled out and damaged.
