Save time and money and improve safety on your next construction project with this proven steel embed plate.

The videos below walk you through the features and benefits of patented the EM-BOLT boltable steel embed plate and demonstrate how easy it is to use. 

By eliminating the field welding step of fixing structural steel beams to concrete foundations the patented EM-BOLT steel embed plate provides a range of advantages including:

  • Reduced beam installation time
  • Eliminated delays due to weather or skills being tied up with other work
  • Improved safety (no welding on ladders or in bad weather)
  • Reduced inspection costs and delays

Embedded Plate Installation Detail 1:

The EM-BOLT boltable embedded plate design is installed inside the concrete form as would be a traditional embedded plate. A chalk line is snapped on the form indicating top of plate elevation and the plates are aligned to this line.

Embedded Plate Installation Detail 2:

The EM-BOLT embedded plate is provided with a centerline slot at the top of each plate. This is for horizontal location. Clip angles for the embedded plate to structural steel joint will have horizontal slots in both legs to allow for movement in both directions due to minor mis-alignment of plates in concrete.

In a typical design, ¾” bolts are used and the slots would be 1 7/8" long, so the clip angle can move 1/2" each way off center. This means that each EM-Bolt embedded plate needs to be within 1/2" either way of center.

Occasionally an embedded plate is positioned outside of this tolerance. If so, the clip angles can be fabricated to align with the installed position of the embed plate.

The EM-BOLT embedded plate is fitted with decking screws at all (4) corners. This makes installation possible with one person. This person can hold the plate in place and drive the screw in without a helper.

Here’s what an EM-BOLT embedded plate looks like in place. You’ll note that the plate is slid into place between the form and the rebar. Bolts provided as part of the EM-BOLT assembly are then added.

Embedded Plate Installation Detail 6:

Occasionally, across a large number of embedded plate installations, a bolt installation or two is missed. As in the picture below, as soon as the plastic protective cap is removed, it’s easy to see that the concrete is visible.

If this is the case, the concrete is drilled out through the existing hole in the embedded plate  and the location where the bolt would have been is replaced with an adhesive anchor.

The difference between the EM-BOLT boltable embedded plate and a standard welded plate is that the embedded plate to structural steel joint is bolted as shown below, rather than welded. This saves significant project costs.

In addition to being easy to install, the EM-BOLT boltable embedded plate is a more reliable connection and can be easily designed into any project.
