OK, sorry about the clickbait title there. But the way these roof trusses are constructed makes me think of an old sewing basket or tackle box.
This was a commercial inspection of a manufactured building or “industrialized building” as labeled on the tagger. The rafter portion of the truss was a folding affair. Held together entirely by a metal joint on a bushing, it appeared.
My question is, once the roof was unfolded, should there have been braces put in, at least at the lower hinged portion (of the rafters … holding the roof) in moral support of those hinges? I would have, but I’ve been known to overcook an egg.
I have no reason to doubt this was executed as engineered/approved but just wondering what others think. I know none of us were there in Elkhart when the thing was whacked together.
Considering it is a Modular Building, it is an Engineered assembly, (multiple sections), and it appears to be constructed/assembled as I normally see them. If you see nothing that looks deficient or damaged, I simply let it pass and move on.
Certainly is an engineering question. Which spans are in compression or tension etc. I would say the wall and the king jacks are doing all the heavy lifting. Obviously that lower hinge is doing little.
Thank you.
There was one damaged one, so I’ll call that out of course. I’ve been in modular home attics a bunch of times, but I hadn’t seen this type of assembly before. Glad I did this one today.
It’s really the gap and the hinge bothering me visually, I think. It’s like they cut and gapped the rafter and joined it with a swivel plate. I’m sure it’s legit, just like snapping on a carabiner and jumping off a cliff. Nein, danke!
Most likely you’ve seen this design… https://youtu.be/sf9_V6yjqlA?si=DgRlj_koZFzWvptK
Pivot location varies with structure design and location to be placed.
Browse through YouTube… there are lot’s of video’s with varying designs of Modular roof systems.
Yes sir, this is the thing. Thanks again. And a good reminder to me to source inspectapedia more often.
Or they were there and just buried in loose fill.
