4” Wood beam clamps for lighting grid

[one-highlander]

My structural engineer has given us our weight ratings and load capacity based on this type of wood beam clamp.

After a cursory search, I’ve found two-piece clamps (https://adaptivetechnologiesgroup.com/wp-content/uploads/DATASHEETS/BC-LAM-KIT.pdf), but not exactly his recommendation. Anyone have a brand, or manufacturer I should look to?

These are for structural 4” x 14” beams that run along the ceiling of a commercial building

Thanks!

From the drawing I'm assuming he expects it to be fabricated by a local welding shop.

You are most likely going to need them to be custom made. I doubt you'll find an off the shelf solution.

I recently made similar points made of 3/8" material that were two pieces, engineered to go into concrete beams, to hang battens. I'm pretty sure we can manufacture these for you. If you're interested, you can email [email protected] for a quote.

I would also consider asking how he felt about a single shoulder eye bolt horizontally through the beam. It would need to be large enough so you get the desired capacity since you would be coming off the eye at 90 degrees to the shaft. But that might be more economic.

Can you get all the way around the beam? I.e., over the top? If so, fabricate something out of 1-1/2" or 2" x 1/4" strap iron with a bolt (3/4"?) through the overlap below the beam.

Unfortunately no, that would make things too easy

Just get them made. Premade wouldn't be much cheaper and this is no place to shave costs. You'll have the comfort of the engineers stamp on the whole thing!

Yep, Get them made. Are those solid 4x14'S? They don't look like glulams.

You can also recreate the adaptive technologies concept with strut L brackets and short sections of strut. That way you have the ability for adjustment based on beam thickness.

Be sure to have them made by a properly certified welder (person, not machine). For example, I COULD make these, but I SHOULDN'T, and I WOULDN'T.

Thank you, I think I'll do that. Yes, they are solid 4x14, per the engineer.

Got it, thank you. I've sent to a local fab shop and they're going to do for me

Also look at the brackets that hold the wood beams to the steel !
