Remember when we had enough room to build a house?

"I want a house."

"We can squeeze one in here."

"Oh..."

"For $800K."

"Ooh...."

"You don't want it? There's a line."

"Okay..." 😔

I don't see floor trusses used too often so it's neat to see them here

[–] schmidtster@lemmy.world 11 points 2 years ago (2 children)

It’s used so the other trades don’t wreck all the TGIs by putting incorrect penetrations. It has all the holes they could possibly need, but sometimes they’ll stick cut a plate….

[–] money_loo@lemmy.world 3 points 2 years ago (1 children)

Holy shit this explains so much!

Our dishwasher in a 2010s era home finally died, and when we pulled it out to install a new one there were these off center holes behind it!

Like, wtf? Why did you need three holes for one cord?

I guess during construction different people thought it wise to drill different holes for different things?

[–] Theharpyeagle@lemmy.world 2 points 2 years ago (1 children)

How are floor trusses different from regular floors? What are TGIs and incorrect penetrations?

Thank you if you have time to answer.

[–] schmidtster@lemmy.world 3 points 2 years ago

There isn’t really any type of “regular” floor in wood, but the 3 most common are dimensional lumber (2x10s for example), engineered joists (TJIs which are dimensional top and bottom chord and OSB web) and engineered trusses (what you see here, dimensional chords and webs.

I apologize for that typo, it’s TGI I-Joists, explained above briefly. The incorrect penetrations can happen in either dimensional joists or engineered joists. The easy rule of thumb is no more than 1/3 the diameter of the material (9” joist being 3” max) and has to be in the inner 1/3 (9” again so no holes within 3” of the top or bottom of the joist.

Now most engineered joists come with pre penetrations and any deviation without their express consent can void their warranty, BUT following general guidelines shouldn’t lead to any issues.

[–] nomecks@lemmy.world 3 points 2 years ago (1 children)

I'm seeing them more and more, which means OSB is probably too expensive to use for engineered trusses now.

[–] schmidtster@lemmy.world 8 points 2 years ago

It’s a trade off, more expensive, but you’re not replacing them because some trade made an incorrect penetration.

Basically you’re paying more to prevent issues later.

And I took a picture of it.

[–] Dozzi92@lemmy.world 11 points 2 years ago (1 children)

I like the picture. I like how the wood pops against the clouds. And the green of the tree. It is perfect for a sub(Lemmy) dedicated to pics, which I believe to be short for pictures, but don't quote me on that.

[–] FleetingTit@feddit.de 3 points 2 years ago

We call them "communities" here, subs is reddit.

This looks like the US. For someone from outside the US, this might be very interesting, because it's very different than what you might see in other countries, especially in Europe, where everything is brick and mortar inside and out.

[–] nailbar@sopuli.xyz 4 points 2 years ago (1 children)

Hmm, must be different from region to region within Europe. Wood is a popular building material in Finland, at least.

[–] GiddyGap@lemm.ee 3 points 2 years ago

Yes, there are areas of Europe where wood is the main building material, like in Finland and Norway, because wood is so abundant. Same in northern Sweden. In southern Sweden, it's mostly brick and mortar.

I'm currently in a neighborhood that was empty farmland as far as they eye could see just 5 years ago. I had never seen a building being built before, but now I drive past 4 complexes being built just on my way to the grocery store. They're also building a closer grocery store.

This area is going to be so nice in like 5 years, but right now it's an absolute mess of construction, road widenings, putting utilities in the ground, etc. We didn't even have cell access here when I moved in 9 months ago.

[–] datavoid@lemmy.ml 1 points 2 years ago

I had never seen a building being built before

Must have been nice

[–] ikidd@lemmy.world 9 points 2 years ago (1 children)

ITT: Bricks good, wood bad. Nobody with a clue about thermal bridging and energy efficiency to be found.

[–] banneryear1868@lemmy.world 4 points 2 years ago

Or how frames work

[–] callouscomic@lemm.ee 6 points 2 years ago (1 children)

Everyone in the comments is suddenly a construction and climate expert.

[–] MrJameGumb@lemmy.world 5 points 2 years ago

I just thought it looked cool lol

[–] Hazdaz@lemmy.world 6 points 2 years ago (2 children)

This looks like the perfect Lemmy post.

A bunch of people who know fuck-all about the subject matter at hand (in this case construction), and then sprinkle in the usual anti-American bias that flavors a large number of posts on this site. The only thing missing seems to be something dealing with Linux or some pro-commie spin.

[–] nxdefiant@startrek.website 4 points 2 years ago (1 children)

At least they're using an open framework. I hope the plans are GPL compatible.

[–] Hazdaz@lemmy.world 3 points 2 years ago

Those 2x4s don't look open source to me. Must be some proprietary M$ stuff.

[–] AlexisFR@jlai.lu 1 points 2 years ago

Don't forget all the top comments criticizing other comments!

[–] x4740N@lemmy.world 3 points 2 years ago (5 children)

I always wondered why american houses are destroyed so easily in storms

I now have my answer

[–] joel_feila@lemmy.world 1 points 2 years ago (1 children)

So what would you build a house out that can take 400 kph debris storm

[–] x4740N@lemmy.world 1 points 2 years ago (1 children)

I would leave it to the experts knowledgeable in the field to help engineer and design a house like that and let them manage the building

[–] joel_feila@lemmy.world 1 points 2 years ago

Yeah that what they would pick that kind of house.

[–] creditCrazy@lemmy.world 1 points 2 years ago

Yea it takes a few decades to get this far
