Level floor joists for chipboard bump against exterior walls

[Haz6909]

Drawing on a floor structure that will have 22 mm floor chipboard on it.
How do you usually do it at the yellow markings on the outer edges? Where the beams are covered by outer and inner walls, which means the chipboard doesn't get any support.

Do you put noggins in the same dimension as the beams to support the chipboard, or how do you do it?

How do you usually handle the areas at the yellow markings on the outer edges? Where the joists are covered by outer and inner walls, meaning the floor chipboard does not get any support.

Do you install noggings in the same dimension as the joists to support the floor chipboard, or how do you do it?

You have an additional joist on the inside of the wall, then you install noggings between the joists where the wall crosses the joists with a 45x45 as support for the floor chipboard.

You have an additional beam on the inside of the wall, then you place cross-beams between the beams where the wall goes across the beams with a 45x45 as support for the floor chipboard.

Ok thank you

So an extra beam in full height to the right in the picture and between the beams a 45 * 45?

You don't need to run full height on the beam that runs along; I would have set a 95 rule, it's more than sufficient.

So an extra beam at full height to the right in the picture and between the beams a 45 * 45?

Did a quick sketch for you😉

Very kind thank you 👍

Since the walls are 120 mm, only 15 mm remains of the extra support beam; is that enough?

Since the walls are 120 mm, there will only be 15 mm left of the extra support beam, is that enough?

You can place 45x70 in between and insulate the gap before you mount the other beam...45+70=115mm, then you have 40mm left to screw the floor chipboard into...
If you want more, you'll simply have to take something wider...

Do you mean that I should fill in with standing 45 * 45 in the column I marked with red arrows?

Ok, do you have double outer frames?
Because if you have double frames, then 45x45 is enough...

Only at the right arrow, you can have either 600 c/c or 1200 c/c on the blocks so that the insulation fits between them...

Hello, can I ask which drawing program you have used? 👍

 

[Haz6909]

Yes, the outer frame is 2 * 145 all around. I drew a new sketch where the standing 45x45 (red in the picture) with 60 cc (in the gap between the outer frame and the extra beam).

Shouldn't the long side of the floor chipboard against the outer wall on the left also have a support rule underneath, with the same principle, standing 45x45 (red in the picture) between the outer frame and the noggings?

On the long side, the 45x45 only has the task of taking up the deflection of the chipboard floor so that it doesn't flex between the beams, so it's not needed if you screw glue the chipboard floor.
At the end, however, the first beam is part of the load-bearing floor construction that is meant to take up the actual weight that the floor is subjected to.

Hi, may I ask which design program you've used? 👍
