J type L type customized shape bolt foundation bolts Screw Nut Bolt

The tensile capacity of the anchor bolt is the tensile capacity of the round steel itself, and the size is equal to the cross-sectional area multiplied by the allowable stress value (Q235B: 140MPa, 16Mn or Q345: 170MPA) is the allowable tensile capacity during design.

Anchor bolts generally use Q235 steel, which is smooth and round. Rebar (Q345) has high strength, and it is not easy to make the thread of the nut. For smooth-round anchor bolts, the buried depth is generally 25 times the diameter, and then a 90-degree hook with a length of about 120mm is made. If the bolt diameter is very large (such as 45mm) and the buried depth is too deep, the square plate can be welded to the end of the bolt, that is, a large head is enough (but there are certain requirements). The buried depth and the hook are to ensure the friction between the bolt and the foundation, so that the bolt will not be pulled out and damaged

Usage
1. Fixed anchor bolts, also called short anchor bolts, are poured together with the foundation to fix equipment without strong vibration and impact.

2. Movable anchor bolts, also known as long anchor bolts, are detachable anchor bolts used to fix heavy machinery and equipment with strong vibration and impact during work.

3. Expansion anchor bolts are often used to fix simple equipment or auxiliary equipment that is standing still. The installation of expansion anchor anchor bolts should meet the following requirements: the distance between the bolt center and the edge of the foundation shall not be less than 7 times the diameter of the expansion anchor anchor bolt; the foundation strength of the installation expansion anchor anchor bolt shall not be less than 10MPa; there must be no cracks at the drill hole, and pay attention to prevent The drill bit collides with the steel bar and buried pipe in the foundation; the diameter and depth of the drill hole should match the expansion anchor bolt.

4. Adhesive anchor bolt is a kind of anchor bolt commonly used in recent years, and its method and requirements are the same as anchor anchor bolts. But pay attention to blowing the sundries in the hole when bonding, and not get damp
