L-bolts, also known as anchor bolts or 90-degree elbow bolts, are a special type of bolt with a 90-degree right Angle between the head and the shank. They are widely used in scenarios such as fixing equipment, steel structures, and pipelines. Its features are mainly reflected in structural design, installation methods and applicable scenarios, as follows:
I. Structural Features
Right-angle elbow design
The main body of the bolt is divided into the "screw section" and the "head section", which are perpendicular at a 90-degree Angle. The head section is usually shorter (similar to a "bent hook") and can be embedded in concrete or foundation to enhance the fixing force through mechanical interlocking.
Diverse specifications
The diameter, length and head section length of the screw can be customized according to requirements (such as M10-M60, etc.), and the surface can be treated with galvanization, blackening, hot-dip galvanizing, etc., to enhance corrosion resistance.
Ii. Performance and Installation Features
Strong anchoring force
After the head section is embedded in the foundation, it can resist tensile and shear forces through the dual effects of "mechanical locking" and "friction force", and is less likely to loosen or be pulled out than ordinary straight bolts.
Installation requires pre-burial
Usually, the head section is embedded in the foundation before the concrete is poured, while the screw section is exposed above the ground. After the concrete solidifies, it is used to fix the equipment base. It has high stability after installation, but precise positioning is required in advance.
Adapt to complex forces
It can withstand vertical loads (pressure), horizontal tensile forces and torsional forces, and is suitable for vibration and shock environments (such as machine tools, fans, bridge bearings, etc.).
