Fixing wall plate to steel.

Screech20 · 11 Jan 2019

Hey guys,

Hoping for some advice on how to fix the timber wall plate to the steel that’s going to run along my extension opening. (203 x 133 x 25 UB)

The walls are up to plate height, which will then be bedded in with mortar.
The padstones are in place ready for the steel to be plonked on.

With some measuring today it looks like the steel is going to fall just below the top of the wall. Originally I thought it was going to need a brick course to make it up, but some measuring must’ve been out somewhere.

So wondering what the best to get the wall plate up to level is.

So far I think my options might be:

1, Bed onto the steel with mortar to meet the masonry plate.

2. Pack the wall plate up with timber packers.

3. Fix wall plate directly to steel and them pack the joists up to level (sounds the less likely option)

4. *Your solution here*

I do have a Hilti gun which I will be using to fit x the plate down.

Advice always appreciated.

Thanks.

We always have the flange pre-drilled (say M10's) and bolt the plates to any steels directly beneath. We have the holes staggered each side of the web.

I personally have never fixed using shot fired method but that will be just as good.

Why do you need to fix it down?

Thanks noseall. We had the web drilled but didn’t think about drilling the flange
I’ve got a shot gun anyway so alls good.

What’s best for raising the height of the plate up to the adjacent masonry plate height?

Thanks

Thanks woody. How will that level up the plate?

Cheers

What is the distance from the seat to the steel? I would use all timber. I presume you dont mean that the steel is out of level

Shotfire a 100mm x 50mm (or woteva thickness) piece of timber to your steel then screw your plate to this.

We rarely set the pads first. Rather we dry pack steels then acro them up when the weight us on them, then fit the pads beneath.

No the steel isn’t out of level, it’s just going to be slightly lower than the wall, not enough for a brick course.
Seat to top of steel is going to be around 60mm, so with the 47x95 wall plate, need to raise around 10-15mm

Thanks guys.

10-15mm steel packer under the steel?

On ours they set the top of the steel above the bricks by the same amount as the thickness of the mortar. The plate was bolted to the steel and mortared/strapped to the bricks:

Easiest is to raise the beam to suit the plate depth.

Otherwise bed the plate up, and you wont have the nail it.

Or 3x 100x22 timbers will get you close to 60mm.

Raise the joists

Notch the joists

Put joists on hangers

Thanks guys.

Panic over. God know what happened with my measuring the other day but it looks like I was right the first time around!

OK, I'll stand the emergency wallplate team down.
