Some information about wedge anchor

Views:3     Author:Site Editor     Publish Time: 2018-07-13      Origin:Site

Wedge bolt anchors, sometimes just called wedge anchors, are used in a variety of concrete applications, including hanging signage, setting windows and doors, anchoring heavy loads and even installing electronics or machinery.

 

For concrete, wedge bolts are your best option for any type of heavy use. Wedge anchors can only be used in concrete and will damage other masonry materials from hollow walls to bricks. That’s because they feature an expansion clip. If you’re not working on a solid material such as concrete, the tolerance at this clip decreases steadily and will cause damage to your masonry or anchored items.

 

Anchor bolt vs wedge anchor:

Anchor bolt:

 

1. Anchor bolts are used to connect structural and non-structural elements to the concrete. The connection is made by an assembling of different components such as: anchor bolts (also named fasteners), steel plates , stiffners.

 

2. Anchor bolts transfer different types of load: tension forces and shear forces.

 

3. A connection between structural elements can be represented by steel column attached to reinforced concrete foundatio.

 

4. Whereas, a common case of non-structural element attached to a structural one is represented by the connection between a facade system and a reinforced concrete wall.

 

Wedge anchor:

 

1. Wedge anchors are designed to anchor objects into concrete.

 

2. They are installed into a pre-drilled hole, then the wedge is expanded by tightening the nut to securely anchor into the concrete. They are not removable after the anchor is expanded.

 

How to Install Wedge Anchor Bolts

 

Wedge anchors have specific uses but their installation is straightforward. First you’ll need to drill a hole in your concrete, usually with a hammer drill and a carbide bit. Use a bit that has the same diameter as your anchor. One thing unique about this is you’ll actually need to drill deeper than the wedge, typically about 1/2”, to provide room for debris that will occur during installation.

 

Clean out the hole with a wire brush or some compressed air, and make sure it’s completely free of debris so you can safely install the wedge anchor bolt.

 

Next you’ll want to put the washer and nut on the anchor. The nut should be threaded so its top is level with the top of your anchor. Insert the wedge bolt anchor directly into the hole, clip-end first. Take your hammer and knock the anchor in until the washer and nut are snug with the material. You need at least half a dozen threads below the concrete surface in order to set the wedge.

 

To finish installing your wedge anchor bolts, tighten the nut. Get it tight with your hands, and then take a few turns with a wrench to help it reach the desired installation torque. This motion pulls your wedge anchor up and sets the clip between the steel stud and the concrete.

 

If you’re installing multiple concrete wedge bolts, they need plenty of spacing. All Points Fasteners recommends you use the diameter of your anchor as a guide and leave a dozen anchor diameters between each installed anchor.
