Production description
Please let us know the specific sizes you need so that we could offer the best solutions.
When the mechanical member is installed on a concrete foundation, the J-shaped and L-shaped end of the bolt is embedded in the concrete for use.
The tensile capacity of the anchor bolt is the tensile capacity of the round steel itself, the size is equal to the section area multiplied by the allowable stress value (Q235B:140MPa, 16Mn or Q345:170MPA) is the allowable tensile capacity of the design.
Anchor bolts are generally made of Q235 steel, which is light round. Rebar (Q345) strength, do not make the nut of the wire buckle light round easy. For the optical anchor bolt, the burial depth is generally 25 times of its diameter, and then make a 90-degree bending hook about 120mm long. If the bolt diameter is very large (such as 45mm) and the buried depth is too deep, you can weld the square plate at the end of the bolt, that is, make a big head (but there are certain requirements). The buried depth and bent hook are to ensure the friction between the bolt and the foundation, so that the bolt will not be pulled out.
Foundation bolts, also known as anchor bolts, are used for many industrial and civil engineering purposes. Typically, they secure structural elements to foundations, but they serve other significant functions, such as moving heavy objects and fastening heavy machines to foundations to ensure safe and effective operation. This range means selecting the right choice among the different foundation bolt types is crucial. Your chosen bolt should withstand the forces it will experience in action and work well with the structural elements and machinery.
