No base to attach the outer edge of the floor chipboard

[Derbyboy]

I am going to lay new floor chipboard where the bathroom will be. The problem is that I have nothing to screw the chipboard into at the outer edge against the outer wall.

Any tips?

Place noggings between existing floor joists to which you screw the floor chipboard.

There are three compartments; I can reach the center one to screw a nogging all the way in, but then it gets difficult.

maybe bolt it to the concrete slab

Attach them with angle brackets. Looks like there is space

Do all sides of the floor chipboard need to be screwed?

Joist hanger so it's solved

Do all the boards have to be screwed into the floor chipboard?

Yes, absolutely, and preferably glued too, and that there is support around the entire floor.
I think it looks like you have plenty of room, cut some noggings that clamp a bit and toe-screw them.

Thank you, everyone.

I'm thinking there will be a heck of a lot of screws in the two middle floor joists if I'm going to screw a straight line of kortlingar at an angle.

Should I be able to shift the middle one inward in the bay?

Or you use a balksko. You probably want support as far out towards the edge of the spån as you can.

The wings on the joist hanger are hitting the concrete. If I use a wingless joist hanger, I can't screw in the short beam on one side.

Thank you everyone.

I'm thinking there will be an awful lot of screws in the two middle floor joists if I'm going to pocket screw a straight line of noggins.

Should be able to offset the middle one inward in the section?

I'm no expert, but sure, you should be able to offset inward. The small hanging piece of chipboard will never experience any significant load.

Otherwise, you can always insert in the concrete block, would then choose to put both sill paper and plastic spacers so it's not directly in contact.

I did it like this in similar problems. I first screwed a "kortling" in one of the compartments. I drove the screws a few mm into the wood from each side. Then, in the compartment I just screwed in, I placed a joist hanger without "wings" and screwed it in, which covered the screws that went into the "kortling" in the adjacent compartment. I hope you understand.

What do you think about using these screws for pocket screwing in the floor joists?

Here you have a good screw

An outdoor screw?

My floor joists are 50mm and not like today's joists which are 45mm. Also, I can't access from one side, so the bridging will be attached with one screw from above and one screw from below, angled into the floor joist.
