Wedge anchors are a type of expansion bolt, also known as gecko expansion bolts or simply expansion bolts. This kind of bolt is a fixing device used to create a secure connection on walls or other surfaces. Below is an introduction to wedge anchors from a mechanical perspective:
Structure and Working Principle
A wedge anchor is typically composed of a bolt, a nut, and an outer sleeve. One end of the bolt is connected to the object to be installed, while the other end is attached to the nut. The outer sleeve is a hollow metal tube, usually made of stainless steel or other corrosion-resistant materials, and it fits over one side of the bolt. There are several slots or notches on the outer sleeve.
The working principle of a wedge anchor is as follows: during installation, the bolt is inserted into a pre-drilled hole, and then the nut is tightened. When the nut is screwed down, the bolt exerts an outward force, which causes the outer sleeve to expand. This expansion presses the slots or notches of the outer sleeve into the hole, thereby creating a secure connection. The nut on the bolt can be used to adjust the tightness of the connection.
Application Fields
Wedge anchors are commonly used in construction and structural engineering to fix objects to concrete, brick walls, stone, or other solid surfaces. These bolts can be applied to install brackets, guardrails, pipe supports, ceiling hangers, electrical equipment, and more.
Advantages
Wedge anchors have the following advantages:
- Suitable for extremely solid surfaces, such as concrete and brick walls.
- Easy to install without the need for special tools.
- Capable of providing adjustable tightness, making them suitable for different applications.
- Possessing high tensile and torque load-bearing capacity, delivering strong fixing force.
In summary, wedge anchors are reliable expansion bolts widely used in construction and structural engineering to create firm connections—especially when objects need to be installed on solid surfaces.
