Lay Out and Install Joists

together in a row. So notice here that all of the cuts are offset so that when the next beams go in place, they lock together. Now we're going to look at the second row of support beams. And you can see that he actually has these gapped intentionally. They're still resting on the beams. It's still notched, but that gap allows the weight to be distributed a little better. What are you doing there, Frankie? doing the layout on a 16in on center. All right. So, all of our joists are 16inch on center. It's a lot of joists. Yep. But it's a big it's a big deck. It is. And uh you just got to remember when you do your very first uh measurement on your 16in on center that your first board is at 15 and 1/4. And then measure off of that mark continuously and everything will be on center. So 15 and 1/4 first mark and then from there you measure from that mark the whole way down and everything will be 16 and on center. Yep. Perfect. Y right here on this end beam. I want to show you why we staggered this cut. You can see how it locks together tight. Now, as we walk past the framing of the deck, I want you to see how the joists rest on the beams, which rests on the posts. Everything is locked together. So, your calculations for your ultimate deck height come from the ground up. All right, let's look at a few of the details on this job. Now, with joist hangers, these are called an 810 joist hanger, Frankie. Yep. And what's this? What What do we need to know about a joist hanger? Anything particular? Well, they keep your joist straight up, you know, uh, plum. Um, attach it to the sill plate. So, no movement. Pretty much it. You know, it keeps you on your center. 16 on center, two foot on center. 16 in. Nice and tight. Hi, Elliot. Hello. 16 in on center. Uh, why don't we go 24, Frankie? We could have uh cuz we went with 2x8s. We could have, but uh I went with the extra support cuz it's just so big. Um hot tub down there. Um just to have the just to have the extra support. Everything is always double sillplated all the way around the perimeter of a deck. Correct. Correct. So that's the point with uh Let me slowly walk over here. Hopefully I don't fall through. If I do, the camera's rolling. It'll be probably pretty funny. Not for me, but for you guys watching. Okay. So, why do we double seal plate the perimeter, Frankie? For to hang your post on if you're doing a a wood handrailing. Um, some people attach their lattice to it. It just gives you more support. I mean, more more…
