[Support Beam cleats]

Thank you very much, I am from New Jersey and never had to deal with clay soil or floating walls. This is the first time Ive had to deal with it. Appreciate it, and anyone else who wants to validate this beyond this post, Id appreciate it.

So I am working on building a room in the basement in Colorado with heavy clay soil. The Stantions go 60' + down and there are four support beams going across sections of the basement. The builders placed 45* arms as photo'd from the main floor into the support beam itself.  Can I knock these out? Or are they there for the main floor of the house to move with the shifting of the foundation.   Thank you in advance!!!

[Framing Nail Gun]

So, I do basic DIY projects and have been doing it for some 20 years, but strictly do it as a recreational hobby. I have never attempted a project like the one I'm about to. I found out the wife is pregnant, and now have to build one to two bedrooms in the basement for family and friends to stay in. I live in Denver, CO and are required because of our clay soil to build a floating wall frame. My question comes down to I mostly have Dewalt 20v tools, and I have a 15 gallon air compressor that goes to 210 psi. Does the degree of the framing nail gun matter? What would be the best for this project and why are there different degrees on the gun?? Seems trivial, but I like to buy things once and use them till they are over worked. I am going to pre-assemble on the ground, then nail it in to the rafters. No judging, just want to know before I attempt this for the first time!!   Thanks in advance.!!
