Thread: winder stairs

  1. #1

    Default winder stairs

    Hi guys. I have a set of stairs that have a 90 degree winder at the bottom, and a 90 degree at the top. There is a straight run of stairs directly bellow this set, making the support difficult. Limited drawings attached. I am having difficulty visualizing the inside connections for the upper winder section. I can not build a platform for the last "square step", and simply stack the winders on top of it because of head room limitations bellow. I have a similar scenario on the lower part, but that seems easier to me so far. Any input would be appreciated.

    Your screwed.

    The drawing is showing headroom at 6-6. Experience tells me that you should be striving for a minimum of 7-0 on the plans and you'll often lose 2-4 inches in reality. You're behind the eightball to start.

    I'd be looking to shift that lower unit at least half a foot backwards. If possible, grab another foot and that will allow you some flexibility in how you hang the upper unit.

    As posted your headroom is inadequate. Also, in CT your design doesn't meet code for winders such that your 3" dimension at the inside needs to be 6" minimum, then min 9" at the 12" walk-line.

    Kind of hard to fix later, but check your local code first to see if the IRC was amended, which is where the 6" rule is for CT.

    It looks like the wonder winder platform is built out of 2x4 and the face is 2x12 which would hang down and give you something decent to attach the strait run stringers to. You could carry the angle up after for Sheetrock. According to my math that leaves you with 6'91/4" without resetting calculator for 32nds. I like German stairs Gutentite

    I agree James.

    That set of plans is drawn by someone in lala land. On paper, every line can hold it's own weight, and the weight of the entire house!

    Do the treads not need to be 10" min. in your area? They do here as well as 6'8" min. headroom.

    That's easy: redraw it with proper headroom so it will work LOL.

    That setup was good for the Munchkins but not for people.

    Why is this a rough framing topic?

    because it was posted in two forums by the OP

    It does involve framing adjustments, though!
