G'day, welcome back to Buildsum and
This time i want to go through the process of
Calculating the materials for your wall frames
So as you can, see here I've got a typical floor plan, with the dimensions provided and
Really, what you, want to do is for every wall frame you actually
Want to go through and calculate every wall frame individually i mean there are, some quick tricks that you could, do
but
Yeah, it's a little bit more accurate if you do every wall frame individually so obviously that's going to be a long
Process it's not just gonna take a couple of minutes it's going to be quite
detailed
So what i want to, do i'm just going to go, through this
example i'm only
Going to concentrate on two wall frames so
This, one here which has just got all studs there's no openings or anything in it and
This, wall here which obviously there's a window opening in that wall so
You know once i've done that you could then go through and calculate the rest of the wall frames
and as you see there's a little bit of work in it
So I've got Wall 1 down here no studs sorry, no window and wall 2 has got a windows
So the first thing, we need to work out is our plates top and bottom plate
and simply they are just that however long, your wall is
So, what I've, also done
Before i started i've actually gone through and identified
How, long i'm gonna, make, my, walls or where i'm going to join them and quite commonly, you'll try and join on in an intersection
Just an easy place to join them or if you can't do it on intersection
Like, down here i've just nominated a spot just away, from the window. In the other wall
So i can just easily, but the two wall plates together
Okay, so i've already i've worked out roughly, where i'm going to join
my Wall plate so the first thing the plates. Length of the wall
and obviously one plate at the bottom of the wall one plate at the top of the wall so for Wall 1
It's 3.410m long
Obviously i'm just going to order two at 3.6 rpunding that up to the next orderable length
and Wall 2
3.640 long
I'm gonna order 2 at 3.9
okay, so
That's the wall plates so it's pretty easy
So the next one and even easier than that is the
noggins and
For the walls that I've got a window
Because you don't have noggins running through the middle of your window
Then the timber that would have been used for your noggins drops down and becomes your window sill
Okay, so as i said their noggin sills and door trimmers if you've got a
Door in the wall that the material that we're allowing, would just get lifted up to the top of the doorway
So, that's just easy, that's simply the length of the wall
Okay, our noggins are supposed to be in at every
1350 on 1.350 m up the wall so for walls up to 2.7m high
One row of noggins is fine
For anything, above 2.7 you'd have to add in two rows of noggins and so you'd have to allow that row of noggins twice
But this wall we've only got 2.4 m ceilings so we only need one row of noggins
Again, pretty similar to our plates
We just put the length of the wall in now, some people would say, well why
Not just allow our three lengths for their plates which in a lot of cases you could, do
However in noggins don't have to be the same size as your
framing material, your studs, they can be narrower
So in some cases just better to separate that out
Alright, but it's not that uncommon quite common to just allow our three
plate lengths till there for your noggins as, well
Alright, so there's our horizontal members their plates in our noggins
and our sill and door trimmers, now let's have a look at our studs
Okay, so for our studs the formula is the length of the wall
divided by our stud spacing,(600 or 450 )plus one
Because when we divide
wall by stud spacing, we're actually working at the spaces in between and
Then if the wall has any intersections or any walls butting into it we need to allow
another stud for each intersection because, we have double studs wherever the walls intersect
so for wall 1
1.340 meters long divided by 600 our start spacing that gives you
5. something studs
Now obviously you can't have our point of a stud so we have to round that up to 6 studs
Then, we add the one for the end and with Wall 1 there's no
Walls that butt into it anyway it actually butts into this wall so there's no
Intersection so we end up with 7 studs and
that means
We would order 7 studs at
2.4 all right we've got a 2.4m wall height our studs will be slightly shorter than that, okay
That i've got another video on that and i'll put a link in the description
But for an orderable length you'd have to order 2.4
for wall 2
all right
3.640 m long divided by 600 again that gives you around 5. something studs
So you're, gonna
Say 6 studs
For that part of the equation plus our 1 that gives you 7 and then with
Wall two you have this wall here it butts in there and
This wall here it butts in there so, we have 2
intersections
So our 7 plus 2 gives us 9 studs so 9 at 2.4 for our studs
So they're just our common studs the other studs, we have to worry, about or what are our Jamb studs and
Again, I've doing the Jamb studs separately because
Commonly they're, not the same size as our standard
Common studs they could be, if we're using 35mm
Common studs our jamb studs might be 45mm Thick
And as a general rule, again, two per window for every window
You'd put in 2, just allow to jamb studs
If that window, was say wider than 2.4m
i would probably, allow 4 Jamb Studs
All right and the wider the opening gets the more Jamb studs you are going to have to allow
By the time you get up to have until they are three and four then you've probably
Have to do a little bit more research in the timber framing guide to see just how. Many
Jamb studs you would actually need
So as a general rule for any window
Opening that's sort of less than 2.4m just to lay out two Jamb Studs per window
So obviously with wall one there's no window. So there's no jamb studs wall 2, one window
so 2jamb studs and they're going to be the same length even though they're
going to
sit under a lintel you know the chances of having a lintel that's wide enough to get us down to the next orderable size is
pretty slim
All right, so we're just all out two at. 2.4. for our Jamb studs and
The last thing, we need to work out is our lintels
So the lintel sits over the window, and you're going to get given a window
Opening or on your actual plan they might just might just give you
Like a reference number which goes which you have to refer back to the Window Schedule to get your opening size
Okay, so that's the actual clear space
That the windows, going to fit into now
Obviously your lintels going to have to be a little bit wider than that because it's got to sit on top of your Jamb studs
Okay, so in this case i'm going to, assume that, my Jamb studs are 45mm wide
So i'm going to take the length of the opening
add
45 on either side for my supports that gives me 90mm and that will give me the length i need for my lintel
so
No, no window in Wall 1 so I don't have to worry about that
so wall 2
So my 2.8 my 2.008
For my opening
Plus, 90mm gives me an effective opening
Or lintel length of 2.098 mso technically
for 2mm longer you could order a 2.1. I'd probably
Personally rounded up an order a 2.4
Just to be on the safe so i just had that a little bit extra timber available if i needed it
Ok, so there you, go that's our major timber components that make up a wall frame that's how we work out How
Many of them,we need. Obviously that's only two
Walls you would have to go around and repeat that process for all the walls in your house and then you could
total up your orders
and get that order into the timber yard
