First, the general use of Q235 steel bolt, which is light round. Rebar (Q345) High strength, threaded nut without light round simple.
Second, a simple introduction of anchor bolts:
Mechanical components installed in the concrete foundation, the bolt was J-shaped, L-shaped end embedded in concrete use.
The tensile strength of the anchor bolt is the tensile strength of the round steel itself. The size is equal to the cross-sectional area multiplied by the allowable stress value (Q235B: 140MPa, 16Mn or Q345: 170MPA).
Anchor bolts can be divided into fixed anchor bolts, anchor bolts, expansion anchor anchor bolts and adhesive anchor bolts. In the meantime, it is divided into L type embedded bolt, 9 type embedded bolt, U type embedded bolt, welding embedded bolt, bottom embedded bolt.
