Product Description

Product Introduction 
When the mechanical component is installed on the concrete, it is embedded in the j-shaped, l-shaped end of the bolt in concrete. The tensile strength of the anchor bolt is the tensile strength of the round steel itself. The size is equal to the area of the cross section times the allowable stress value (Q235B:140MPa, 16Mn or Q345:170MPA) is the allowable tensile strength of the design. 
The anchor bolt is usually made of Q235 steel, which is the light circle.The screw steel (Q345) is strong, and the thread that makes the nut is not easy. In the case of a round foot bolt, the depth is generally 25 times its diameter, and then a 90-degree curved hook that is about 120mm long. If the diameter of the bolt is too large (such as 45mm), it can be used in the bolted end of the solder plate, which is to make a large head (but also required). The depth and the hook are all designed to ensure that the bolt and the base friction will not cause the bolt to take out and destroy.

Product Feature and Application
Anchor bolts can be divided into fixed foot bolts, movable anchor bolts, expansion anchor bolts and sticky ground bolts. It is divided into: L type pre-embedded bolt, type 9 pre-buried bolt, u-type pre-buried bolt, weld embedded bolt, and ground plate embedded bolt.
1. Fixed foot bolts are also known as short ground bolts, which are watered with the foundation to hold equipment that has no strong vibration and impact.
2. Movable anchor bolts are also known as long anchor bolts, which are removable anchor bolts that are used for heavy mechanical equipment with strong vibration and impact.
3. The anchor bolt is often used for fixed and simple equipment or auxiliary equipment. The installation of the anchor bolt should meet the following requirements: the distance of the bolt center to the base edge is not less than 7 times the diameter of the anchor bolt; The base strength of mounting anchor bolts shall not be less than 10MPa; There shall be no cracks in the borehole, and the drill shall be prevented from colliding with the rebar and buried pipe in the foundation. The diameter and depth of the borehole should match the anchor bolt.
4. Sticky grounding bolt is a kind of anchor bolt used in recent years, and its method and requirement are same with the expansion anchor bolt.But when sticking, pay attention to clean the hole, and not damp.
