Hello!
I have a space where I am planning to build a recording studio.
The space is a roof of a workshop, which in turn is located in a large hangar-like building.
My floor (the ceiling of the space below) consists of 22mm chipboard glued and nailed to 45x145 joists cc600, which in turn sit on 250mm I-beams, cc2400. The beams are supported by standing beams and joists of 45x145mm.
Now to my question:
I want to build walls that will stand on the chipboard floor, can I do that?
I assume there are no issues with walls running perpendicular to the joists under the chipboards, but what about the walls that might run along the joists and land in the middle of a chipboard?
Some of the walls will be up to 6-7m high and they will need to support a ceiling and in part of the space also support an upper floor.
How do you best reinforce the floor to support the walls?
I have considered 12mm, 19mm, or 22mm construction plywood, or placing 45x45mm 645mm long joists on the chipboards so they take up the weight and transfer it to at least 2 of the underlying 45x145 joists.
Are there simpler, better ways?
How much can 22mm chipboard hold?
I am very reluctant to break up the chipboard floor and reinforce it from below, as it is glued to the joists...
