Name stiffening anchor plate bolt, bolt welding, claw anchor bolt, bolt reinforcement plate, feet tied, anchor bolts, to the foot wire. Designed for buried concrete foundation, as fixed all kinds of machinery, equipment used in the base. 7 word bolt to bolt a more commonly used. Q235 commonly used steel production, the use of high strength materials processing Q345B or 16Mn, 40Cr material is also useful for processing 8.8 intensity of products, occasionally also useful for two or three steel processing. There are different bolt wool, thick shaft, thin rod form of points. That is the raw material of steel wool without restructuring, processed from bar or wire directly; thick shaft otherwise known as A-type, B-type shank or called, by the steel processing after conversion into the corresponding requirements of the rod diameter. Welded by a single stud anchor bolts welded iron after stiffening. Its anti-pulling ability. Depending on the conditions used, respectively, can reach 3.6, 4.8, 6.8, 8.8 and so on grade. Tensile strength 3.6, 7 anchor bolt tensile strength of the steel itself. Q345B 16Mn material or its direct processing of bolt tensile capacity can reach 5.8 tensile strength. 4.8, 5.8, 6.8 and 8.8 of the tensile strength of the reference GB / T3098.1 in provisions for the mechanical properties.
