A beam pocket is a recessed area to hold the end of a beam in a concrete or masonry wall. The beam pocket is an opening to receive a beam in a vertical structural member. It is an opening in the form for a column or girder where the form for an intersecting beam is framed.
The pocket is created by cutting out a hole where the beam will sit, and then creating a place-holder block out of lumber and putting that block in the hole. Once the concrete has been poured around the block, take the block out and your left with a pocket in which the beam will sit. The wet concrete will flow behind and below the block to create a nice square pocket in the concrete.
Types of Beam Pocket
A beam pocket is available in either disposable or reusable formats. They can be nailed to a plywood form to create a block out in a concrete wall for beam pocket placement.
