Top Suppliers Fixing Anchor Bolts Into Concrete - Welding anchor bolts and embedded anchor bolts – Chuan Ding

Product Description

>>>

When the mechanical components are installed on the concrete foundation, the J-shaped and L-shaped ends of the bolts are buried in the concrete for use.

The tensile capacity of the anchor bolt is the tensile capacity of the round steel itself, and the size is equal to the cross-sectional area multiplied by the allowable stress value (Q235B: 140MPa, 16Mn or Q345: 170MPA) is the allowable tensile bearing capacity during design.

Anchor bolts generally use Q235 steel, which is smooth and round. Rebar (Q345) has high strength, and it is not easy to make the thread of the nut. For smooth-round anchor bolts, the buried depth is generally 25 times the diameter, and then a 90-degree hook with a length of about 120mm is made. If the bolt diameter is large (such as 45mm) and the depth is too deep, you can weld the square plate at the end of the bolt, that is, just make a big head (but there are certain requirements).

The buried depth and the hook are to ensure the friction between the bolt and the foundation, so that the bolt will not be pulled out and damaged.
