View Full Version : Walk-In Structural Integrity

06-29-2015, 06:27 AM

We've almost finished our new walk-in cooler with used panels from Barr Refrigeration.

Our wall panels interlock wtih each other, so while each individual wall is structurally sound, we're struggling with how to attach each wall to the next at the corners. We're using large lag screws designed for insulated panels, but they dont do much to prevent the panels from pulling off of each other, they just stop them from moving side to side. There's a boot attached to the floor that helps down low, but these paners are 12' tall.

All outside corners will eventually be flashed, as will inside corners, but these are really meant for sealing, not structural integrity.

As we've built the unit, we've been running large ratchet straps around the outside to hold it all together, but this is not really a permanent solution. I'm looking to you all for suggestions.

Call the guys at Barr refrigeration- they can probably help. http://www.barrinc.com

We made some straps from galvanized steel roofing flashing--the stuff that comes in rolls--and used numerous sheet-metal screws to secure them around the corners. We used silicone sealant on the seams before covering them with the flashing metal.

When you are missing CORNER panels here is what you can do if you feel you are not getting the solidness you want.
First thing what you need to do is use a large piece of Galvanized 90 degree angle to join the corner vertically on the outside.
At least 2 inch deep angle. Before you assemble the corner use either butyl or urethane caulk is also good.
Use long lags from the ceiling panel downward.
Lastly, you can set steel angle at the floor both inside and out and then bolt thru if you need major stability.
You should be fine with this approach.

Other outfits as well are shipping a hodge podge of used panels that are not necessarily an interlocking set from the same original box.

What they are not saying anything about is the carpentry involved to make it then work out, which would have been nice of them to mention with details and Techniques.
