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.
Installation Method
1. One-time burial method: When pouring concrete, bury the
Foundation Anchor Bolts. When high towers, etc. are controlled by overturning, Foundation
Anchor Bolts should adopt a one-time burial method.
2. Retaining hole method: When the equipment is in place, clean the hole and put the Foundation Anchor Bolts into the hole. After the equipment is positioned and corrected, use a non-shrinkage fine stone concrete that is one level higher than the original foundation to water and compact the hole. . The distance from the center of Foundation Anchor Bolts buried once to the base edge should not be less than 2d (d is the diameter of Foundation Anchor Bolts), and should not be less than 15mm (d≤20 should not be less than 10mm), not less than half the width of the anchor plate Adding 50mm, when the above requirements cannot be met, appropriate measures should be taken to strengthen it. The structure of the Foundation Anchor Bolts should not be less than 20mm in diameter. When subjected to earthquakes, double nuts should be used for fixing or other effective measures to prevent loosening, but the anchorage length of Foundation Anchor Bolts should be increased by 5d than the non-seismic anchorage length.

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.
