    J / L / U / V Shaped Anchor Bolts Concrete Foundation Grade 12.9 High Tensile



    Product Description



    The tensile strength of the Foundation Anchor Bolts is the tensile strength of the round bar itself. The size equal to the cross-sectional area multiplied by the allowable stress (Q235B: 140 MPa, 16 Mn or Q345: 170 MPA) is the allowable tensile strength at design time.
    Foundation Anchor Bolts generally use Q235 steel, which is light round. Rebar (Q345) has a high strength and it is easy to make the screw thread of a nut without a roundness. For the Foundation Circle Anchor Bolts, the buried depth is generally 25 times its diameter, and then a 90-degree long 90-degree hook is made. If the bolt diameter is too large (eg 45mm) to be buried too deep, the square plate can be welded at the end of the bolt, ie it can be a big head (but it is also required). Both the depth of burial and the hook are used to ensure the friction between the bolt and the foundation so that the bolt will not be pulled out.



    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.

    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.




    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.
