An Anchor is a type of fastener that utilizes friction to form a secure hold in a pre-drilled hole. This friction is most commonly achieved via an expansion mechanism. After installation in a pre-drilled hole, the anchor is designed to expand in diameter, forming a tight wedge against the inside of the base material. Wedge anchors, wall plugs, hollow wall anchors, drop-in anchors, shield and expansion anchors all make use of this expansion method. A key benefit of this type of anchor is that it can bear a load immediately upon installation, as opposed to chemical anchors which need to cure, making them ideal for speed-critical applications. There are many varieties of anchors to be used in specific applications.
COMMON TYPES OF ANCHORS:
Clamping Anchors: An open conical body, a pair of plastic wedges, and a flexible bail with an insulating thimble make up these anchoring clamps. When the bail is passed through the pole bracket, it can be latched onto the clamp body and re-opened by hand at any moment when the clamp is not fully loaded.
Concrete Wedge Anchors: Materials and equipment are anchored and secured to solid concrete masonry surfaces using Concrete Wedge Anchors. It is not advised that they be utilized in other masonry materials.
Anchor Rods: Anchor rods are threaded fasteners that are embedded in concrete foundations to support light poles, traffic signal poles, structural steel columns, highway sign structures, steel towers, industrial equipment, and a variety of other buildings.
Screw Anchors: Screw anchors are inserts made of plastic, metal, or fiber that allow screws to be inserted into fragile materials like masonry or drywall.
Under Anchors: Ground anchors, also known as earth anchors, are multifunctional devices that are used to permanently or temporarily hold, constrain, and support buildings, engineered slopes, and other structures.
Sleeve Anchors: Door frames are also attached to concrete, brick, or mortar walls using a sort of Sleeve anchor. For this type of application, sleeve anchors are typically employed. The Sleeve secures the door frames to the building’s framework or the doorway’s thresholds.
