Deck drawing, don't understand...

[Cgong]

Hello
I have looked at byggbeskrivningar.se's attefall drawing. It's the deck drawing that I don't understand - can I - if I choose to lay the decking perpendicular to the façade - increase the cc measurement from cc600 to 2m? I was thinking of using 34x125 as decking.

If you want to lay the decking perpendicular to the facade, the joist construction needs to be completely different. You can skip all the small floor joists. If you reduce the distance between the support beams slightly to 7500 mm, it is fine to lay 34x145 directly on them. The decking will then overhang slightly on both sides, but that is OK at least from a stability perspective.

If you reduce the distance between the support beams to 7500 mm, it will work to lay 34x145 directly on them.

750 mm right?

750 mm of course.
