Basement walkout wall with a tripple beam?

Hello again everyone,

I am still framing my basement. I have another non load bearing wall I will be building. after measuring it out, this wall will be perpendicular to the framed exterior wall of the walkout side of the basement. I see right where the wall will intersect there is a triple stud with OSB plywood in between each stud, so essentially 5.5" thick. My assumption is this is a load bearing stud or something like that? I will need to add another stud next to it in order to allow a surface for sheet rock to attach to.

Since they are 2x6 studs on the outside wall, can I just sister a 2x4 to the side and nail it to the triple stud? My theory that would allow 2" of insulation behind the sistered stud, and also give me the surface area I need for future sheetrock. it also feels faster than nailing small sections of 2x4 like a ladder between the triple stud and the one next to it. Is this type of thing allowed? or do I need to do the ladder, or do I need to figure out how to not touch that triple stud?

Yes, that sounds like a structural beam. And, yes you can sister to the beam to make it easier to attach your non structural walls and sheetrock.
