GB 5782-86 Grade 10.9 M20 Foundation Anchor Bolts For Concrete
Building
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.

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.
