Bottom/sill plate fasteners

[Orangetractorkid]

I’m moving a garage on my property and had a slab poured without anchor bolts. I did not want the bolts in the way of the garage when it was being moved. What is a good option for fastening the 2x4 bottom/sill plate to the concrete floor? I’ve been looking at Simpson Titen HD in 1/2 x6” but am curious about the expansion type redheads.

Thanks!

Is this a slab only, or thickened on the edges? Most expanding type anchors have rules on how close to edges they can be. I would recommend going with the simpson epoxy in anchors, or the titens. Both are great and can be used in this application.

It’s thickened on the edges. It’s floating, no footing. Thanks for the reply!

I used expanding anchors on my place.

With epoxy there’s no chance of breaking the concrete, why chance it’s?

Is the curing effected by the cold? I’m in Minnesota and the lows right now are in the thirties. How deep should the rod be set in the concrete?

This is typically spec'd by the engineer but I suspect the simpson tables show a minimum. I had to do a few anchors in my garage that had to be relocated and my embedment was 6". It was december when I did mine, definitely very cold. I put them in but didn't tighten the nuts for a few weeks. They did take a bit longer to set for sure in the cold. It was below freezing day and night when I did mine. There were some places we used titans also and they are easy to do and done as soon as you put them in.

I’ve heard with a 2x4 bottom plate these are susceptible to blowing out the concrete due to it being so close to the edge. I have a Hilti hammer drill so the holes are a problem.

Head to Menards or Home Depot and see what they have on the shelf for epoxy. The working temps should be on the tubes and get ready for some sticker shock.

As to depth and qty I'm not sure. It doesn't sound like this is a move your permitting or have engineering for so I'd google and see if you can find a common connection detail that shows depth, qty and diameter then add a few extra for some insurance.

The good thing about a 2 part epoxy is that it sets up chemically. Generally cold temps slow it down but it still works. However read the label because it could be that it will have a minimum temp listed. I have done some auto repair work where it wasn't set by the time I left for the day but it was fine the next morning.

I'd use epoxy as well as a first choice, titens as a second. Definitely not expansion anchors at that close to the edge

I think there are two types sold at HD and Lowes under the simpson name. One is a two part acrylic and one a two part epoxy and one is better for colder temps if I remember right. Either way, read the labels and see what they say.

This is what I've used for several projects. Works.
