Deflection Track - 4" of deflection required

Deflection Track - 4" of deflection required

Deflection Track - 4" of deflection required

(OP)
Does anyone know of a system out there that will provide 4" of vertical travel in a deflection track (other than a custom bent plate)? The most I can find is around 2". I'm working on a Church that has the main portion built out of a metal building and the metal building guys are giving me L/240 which equates to about 4" of vertical travel. I need to hook my interior steel studs to the roof framing somehow and not have them "crunch" under load.

RE: Deflection Track - 4" of deflection required

Also need to look at the eccentricity on whatever gizmo and fasteners you use with a 5 psf lateral load on the studs.
Call the steel network in Raleigh, NC. They may be able to make you a custom clip but it may be cheaper just to get a custom track made.

I thought about calling them. I will take your advice and do it!

RE: Deflection Track - 4" of deflection required

I usually see the studs just installed tight to the beams and never observed a problem. (not that I would design it like that)

RE: Deflection Track - 4" of deflection required

CBSE, see page 8 of link below. I don't know how your wall aligns with the structural steel, but if you could manage to get that clip fastened to the structure, I believe this would give you all of the deflection you required.

I think that would probably work for my application. May take a little additional steel to get the connection in there, but that is definitely probably a cheaper option than custom bent steel plate.

Thanks for the Info!!!

Firetrak manufactures deep leg tracks (up to 6" deflection) for rated walls: Firetrak http://www.firetrak.com/
