Fasteners For Brick Ties Into Structural Steel Studs.

dom-mas

As the title says, what kind of fasteners has anyone used to anchor brick ties into structural steel studs. I'm off to the hardware store soon to see what they have but I thought I'd ask here.

Not looking for anything that requires a special tool or anything too expensive since I doubt I'll run into anything like this again for quite a while. something cheap, fast and easy

Thanks

Mostly a self tapping screws with a epdm washer.

Shoot why didn't I think of that? Steel roofing screws. I was trying to give away a box I bought for when I was going roof my shed but went with asphalt instead. I'll have to go and see if the screw will fit through the hole in the brick tie.

Thanks NJ, twice you've saved my butt.

dom-mas

Yup, those will work great. Hopefully I can return the favour sometime NJ but something tells me you've got just about everything covered.

NJ Brickie

No problem. That is what this forum is mainly about. Exchange of information here is great. My knowledge is mostly commercial, especially institutional work. I have built a few fireplaces years ago but today I would have to open some of my old masonry text books to build one again. Or just come here for info. Residential is not my thing.

dom-mas

Bah, residential is the same. Just way less space. This job has a wall that's 20' long and 25' tall with no openings. I haven't seen anything like it in years. I rarely get 10o sqft without a window or door.

Would self tapping lath screws be sufficient?

Also why use a screw with the rubber washer? Is there a reason?

rustyjames

I've never seen rubber washers used, just washer headed self-drillers.

dom-mas

What are lath screws? I think NJbrickie suggested those because they're readily available, cheap and fast. I don't think the rubber washer is important, but any hardware store carries them.

The biggest problem with wrinkled tin studs is that any screws strip off the protection and offer a great place for corrosion to occur.

Brick ties can carry the moisture in and cause long term problems especially if it is a loose specification.

Why worry about pennies on screws when there can be bigger liabilities?

If it is according to specs, leave the liability to the designer and attorneys in a few years and cross your fingers.

Ok so what's the solution. I need to put in brick ties. What else can I fasten too, not denseclad? will the rubber washers help to keep moisture out? Maybe that's where you're going with it.

http://www.masoncontractors.org/2011...anchor-system/Good points as usual Dick, though I have had jobs spec'd with these Image A, with rubber washers on the screws.....Maybe the rubber washers are there to keep moisture from migrating to the hole.........something to think about...... That doesn't seem to work, try http://www.masonpro.com/brickveneercommercial.htm

That's it. Type III or Type III seismic. Regular wall ties are not generally accepted for brick veneer/steel studs as there have been failures with high wind loads. Once you use these, you'll be sold.

NJ Brickie

dom-mas- Are you saying that you are screwing on corrugated wall ties? As far as I know wall ties are not an acceptable wall reinforcement for cavity walls in many places. But they are often still used, especially in residential. Dw-10(also know as type3) anchors and and sure tie anchors are what we mainly use for steel stud applications. Wood studs also, but wood has all but been eliminated in commercial work.

The rubber gaskets on the screws are often spec'ed for jobs, My guess would be most jobs, so that is what we buy. The reason the the gasket would be a seal around a penetration you are making I would think. Also it seems that the rubber helps prevent over tightening the screws and stripping out the connection at the stud.

Type III over Denseglas, Type II over wood sheathing. The washers are used for application over membrane waterproofing normally.

Huh, I remember using ties like those on commercial buildings when I was a labourer, but they were installed before we ever showed up.

This job is basically residential. It's a Triplex and built by commercial guys (don't know why, maybe because it's multi dwelling). The 2 main sidewalls are steel stud with Denseglas but the front, back and any jog in walls are wood with OSB sheathing.

As far as I'm cocerned it's not real different than any other residential job except they have a control joint on one of the wood framed walls at 15' out of 18'. From being a labourer on the commercial jobs I thought they were only every 20' at a post. Whatever.

Yes I'm using corrugated brick ties I know they're still acceptable around here unless engineer/architect specs something else. And I think I will use those steel roofing screws, nothing is speced and i have a box of them sitting around.

I have lots more to learn/remember about commercial work.

There just a self tapper with a large, washer type head...

dom-mas

Oh,

Tom Struble

the rubber washer will also help keep the tie in position as you tighten the screw
