Galvanized L shape and J shape eye head Anchor Bolt

Product Overview

Description

Anchor bolts are tools that are buried in the ground or in the foundation to connect the earth or foundation to machinery and equipment. Generally use Q235 steel, which is light round. The strength of the rebar (Q345) is large, and the thread of the nut is not easy to be round. For light round anchor bolts, the buried depth is generally 25 times its diameter, and then a 90 degree hook of about 120 mm length is made. If the bolt has a large diameter (such as 45mm) and the depth is too deep, you can weld the square plate at the end of the bolt, that is, you can make a big head (but there are certain requirements).

 

Both the depth of the burial and the hooks are used to ensure the friction between the bolt and the foundation, so that the bolts are not pulled out. The anchor bolts have the function of fixing equipment without strong vibration and impact. use 1. Fixed anchor bolts, also known as short anchor bolts, are poured with the foundation to secure equipment without strong vibration and shock. 2. The movable anchor bolt, also known as the long anchor bolt, is a detachable anchor bolt for fixing heavy mechanical equipment with strong vibration and impact. 3, expansion anchor bolts are often used to fix static equipment or auxiliary equipment. The installation of the anchor bolts of the expansion anchors shall meet the following requirements: the distance from the center of the bolt to the edge of the foundation shall not be less than 7 times the diameter of the anchor bolts; the foundation strength of the anchor bolts shall not be less than 10 MPa; there shall be no cracks in the borehole, The drill bit collides with the steel bars and buried pipes in the foundation; the diameter and depth of the drill holes should match the anchor bolts of the expansion anchors. 4. Bonding anchor bolts are a kind of anchor bolts commonly used in recent years. The method and requirements are the same as the anchor bolts. However, when bonding, please pay attention to the impurities in the hole and do not get wet. The anchor bolts are generally made of Q235 steel, which is light round. The strength of the rebar (Q345) is large, and the thread of the nut is not easy to be round. For light round anchor bolts, the buried depth is generally 25 times its diameter, and then a 90 degree hook of about 120 mm length is made. If the bolt has a large diameter (such as 45mm) and the depth is too deep, you can weld the square plate at the end of the bolt, that is, you can make a big head (but there are certain requirements). Both the depth of the burial and the hooks are used to ensure the friction between the bolt and the foundation, so that the bolts are not pulled out.
