Framing Exterior Wall Corners - Requested SketchUp Video

okay I'm back for another Sketch up video I had a viewer asked me a question from my last Sketchup video which is pretty cool I like that I'll do your request it's fun his question was related to building corners and how the plates the top plates or even the bottom plates might overlap so what I did was here just save a little time I went ahead and drew out this kind of floor system here just a slab of a floor well pretend it's concrete and don't ahead just draw out some studs and some plates this is just a 12 by 16 just for an example also put some window the start of some window framing in here as an example too because it's related to the to the corner and I'll show you now how it is related to the corner when we start framing a house the first thing we do is we we decide how many window openings there are then we cut the jacks the jack is we call it there's different terms around the country for this but we call this piece right here that's nailed on to the side of this stud where this to before a jack because it's holding up the header and the header is just a 2 by 10 to 2 by 10 spaced apart like that and the reason they're spaced apart so that they're flush on both sides of the wall when you raise it up with a 2 before on the bottom like that ok so you might say well what's that dimension well we cut 10 and 7/8 off of a stud and that block the reason we go ahead and cut these is so that we don't have much waste because we're going to cut 10 to 7/8 off of that for the jack anyway so we count we might have you know 30 or 40 of these things Jack's to cut so we may end up with 30 or 40 blocks that we can make guess what corners of it and I'm going to show you how we can do that right now so I forgot to make the block so that's what I did I'll cut away some sometimes during the video to just try to save time and make things so I just made the little block that used to fit right here and I'll show you that used to fit right there yeah we're gonna take that block and all the other blocks that we cut off and we're going to make corners out of them so it's going to go right here like that so there would be one on each end if I don't make your studs are pre-cut when you buy them for eight-foot walls they're ninety two and five eighths of an inch long so what I'm going to do is I'm going to take another block I'm gonna put it down here I'll this in so I can see I can snap to the corner like that and then I'm just going to copy one in the middle somewhere it doesn't have to be perfect just so we're right there and then I'm gonna take another 2x4 another stud I'll just copy this one and okay right there so now we have a corner of course this is laying down on the floor just like we would lay our walls down to build them before we stand them up so that's that wall and let's just go ahead and fill this wall out with studs while we're here so what we'll do is we'll just copy this one let's go we usually go down 15 and a quarter so that puts the center of it see that's 16 right there see and then we can just copy now we can just copy this one down we'll say 16 times how many do I need 10 10 of them like that and I'll delete these out of here out of the window opening I hope I'm not going into too much to want much more detail than what's requested but you get me started on this stuff I'm gonna make a group out of that and copy it we're down here up there so then we have a corner on each end and the other thing we can do is copy our plates now your first top plate will be an exact duplicate at the bottom one which is if I was actually laying this wall out in real life I would have had two there and I would have marked them Marcos tugs on each of them so that when I brought this plate up we could nail them and they would all be straight let's just say that's a door opening for now at a save time I'll delete that study I was going to make it a window opening but just to save time we'll call it a door so that wall is framed okay so now what we would do let's make it a group so it all stays together and so now what I can do is I can stand up this wall I'll get my little tool here rotate it 90 degrees and pull it back let's put it back in real life we set it back another half inch for our sheeting like that okay then sometimes if it made sense if we were up really high say this was a two second or third story we might even go ahead and nail on the sheeting before we stood the wall up okay so I kind of did that prematurely because I just realized I didn't put my double top plate on let's go ahead and do that I can do it here I'll just pretend I'm on a stepladder doing it so we'll copy this plate oops what i'm gonna do i'm going to ungroup this someone explode this group for now so i can just grab things individually I can always regroup it later so what you do is you actually have two top plates and that makes the wall about eight foot one and a cool and what that does is it gives you some wall height let's go all the way down here and measure I think it's eight foot one and a quarter that gives you room for likes flooring and eight foot one and eight something else close I just forgotten that gives you room to put some floor coverings you know and the ceiling covering and still have about an eight-foot ceiling so now you're seeing back to how the walls tie in this very top plate is cut back when it was laying on the ground three and a half inches and now I think you see where this is going just like that and it would be on both ends and on a short wall like this it that may not make sense what what the double top plate is for let's say this wall was too long I say it was 40-foot long and you had multiple joints is that this this top plate the lower the first top plate well this double top plate would you would laugh it over those joints and it would give your wall strength and it also that's the same thing at the corner what you would do is you build both of your long walls first this is the 16-foot wall and it's a 12 by 16 so you would build a facility for it in a long point go back to here and then we'll go another half inch back so that's what she would have done you would have built both your wealth your long walls first then you would have built your short wall in between so what I'll do again is all copy since I've done all this work I'll copy this and hang it here and [Music] rotate it around there's my 1930s and then I'll take out when we framed this wall this end wall the shorter wall will just let me explode that corner so then it's pieces again we'll take out our blocks we're not taking them out we wouldn't have we would have built it this way on the floor so then when you raise this wall up it is going to be here and one thing I'm not showing is this should have been and moved back a half inch I you know I set this back a half inch well you'd also want to cut your plates back a half inch too so that the sheeting in fact I'll just fix that in a minute I'll go ahead and move a bit this one back a half inch just so it's proper we would have we would have needed this stud because it's on the layout so we'll keep it and we'll just move this over we'll copy another one there and then what we'll do is edit our top plates and now you'll start to see how the overlaps work I'll take that one back to there and this talk one will just go back to here and then one zoom in on that okay so now you see how it works this I don't know this was a long video just to show how that corner works but I'm trying to do two things I'm trying to show how Sketchup works and how to build things so you can see here that this top plate here this one is cut back three and a half inches so that it allows this one to overlap that wall and then it's nailed and that ties your corner together the other thing that ties your corner together is that let me just make a sheet of plywood right quick and I'll be right back so I went and made myself a piece of OS being here didn't take too long was it too bad and I'm gonna go take it and put it where it goes I'll snap to that corner and I'll back out and go in here then we'll go right here see that and so what happens is this sheet overlaps and ties into that wall and then oops forgot I still had it well let's see let's go ahead and copy as a piece you know being this one around and put it where it goes which would be here now really in real life we just take them to the corner we don't try to overlap because it gets bulky because if one of these is cut and you try to overlap it then it gets bulky so the best thing to do there but you can see that it still if I were just to lower it son you can see how the OSB the sheathing is now nailed to this wall and it's overlapped this wall and it's nailed through the corner and that's why wood frame construction is so strong because once that you get your sheathing on the entire perimeter then it becomes a diaphragm it's very very strong that's why you don't see wood frame houses falling down in earthquakes and you'll see the best built wood frame homes even surviving tornadoes to a certain degree if they're not directly hit because we tie the plates down to the concrete and we tie the roofing members to the tops of the walls with straps and that's very and like in places with high winds like in the Florida you'll see there's the corners in other places you'll see a rod coming all the way from the foundation all the way to the top of the wall and the whole wall the whole wall assembly is tied to the concrete to the base and so it's very strong so anyway I hope that helps I enjoy making these videos they may be a little bit long if anyone else has a request I would be happy to do it and if you have any other you know questions about the way things are framed or built let me know and so we can narrow it narrow it down a little bit and I don't spend like an hour drawing these the entire house or whatever so but anyway I appreciate you guys and let me know in the comments what do you think Thanks
