DIN 933 / DIN 931 J Type Foundation Bolt , Heavy Tensile Zinc Plated J Bolts For Concrete Anchoring
Product Description
Foundation Anchor Bolts is designed to be embedded in a concrete foundation and used as a base for fixing various machines and equipment. The 7 word Foundation Anchor Bolts is the more commonly used one in Foundation Anchor Bolts. Generally made of Q235 steel, high-strength use of Q345B or 16Mn material processing, also useful 40Cr material processing 8.8 strength products, occasionally useful secondary or tertiary rebar processing. Foundation Anchor Bolts has different types of wool, thick rods, and thin rods. Raw materials, ie wool, are not restructured, and they are directly processed by round steel or wire rods; the thick rods, or A-type, and the fine rods, or B-type, are all converted from steel rods to the correspondingly required rod diameters. Welded Foundation Anchor Bolts are made by single head bolts after welding stiffened iron plates. Its anti-pulling ability is strong. According to the different conditions used, they can reach grades 3.6, 4.8, 6.8, and 8.8. The 3.6-level 7 character Foundation Anchor Bolts has the tensile strength of the steel itself. The Foundation Anchor Bolts directly processed with Q345B or 16Mn raw materials can achieve a tensile strength of 5.8. The tensile strength of grades 4.8, 5.8, 6.8 and 8.8 refers to the provisions for mechanical properties in GB/T 3098.1.

Classification
Foundation Anchor Bolts can be divided into Fixed Foundation Anchor Bolts, Activity Foundation Anchor Bolts, Expansion Anchor Foundation Bolts and Bonding Foundation Anchor Bolts. According to the different shapes, they are divided into: L-shaped embedded bolts, 9-shaped embedded bolts, U-shaped embedded bolts, welded pre-embedded bolts, and embedded bolts on the bottom plate.
Use
1. The fixed Foundation Anchor Bolts, also known as the short-foundation Anchor Bolts, are watered together with the foundation to secure equipment without strong vibration and shock.
2, Activity Foundation Anchor Bolts, also known as the long Foundation Anchor Bolts, is a detachable Foundation Anchor Bolts, used to fix heavy machinery and equipment working with strong vibration and impact.
3, expansion anchor Foundation Anchor Bolts are often used for fixed stationary equipment or auxiliary equipment. The Anchor Anchor Bolts shall be installed in such a way that the distance from the centre of the bolt to the base edge is not less than 7 times the anchorage of the Anchor Bolt, and the anchorage of the Anchor Bolt shall not be less than 10 MPa; there shall be no cracks in the borehole. Care should be taken to prevent the drill bit from colliding with the reinforcing steel or buried pipe in the foundation; the diameter and depth of the drill hole should match the anchor anchor Foundation Anchor Bolts.
4, bonding Foundation Anchor Bolts is a Foundation Anchor Bolts commonly used in recent years, its method and requirements with expansion anchor Foundation Anchor Bolts. However, when the adhesive is attached, the debris in the hole should be blown off and must not be affected by moisture.
