Avoiding Point Loading of HD Catnic Lintel?

[johnny2007]

How are hangers fixed to a 2 or 3" wall plate in the standard way?

Of course you need a wallplate the same size as the joists.
If you are installing 8x2 joists your wallplate will be 8x2 bolted to the blockwork so to accept the joist hangers.
See picture in first post.
This is basic construction, i'm sorry to say.

not sure where you got the idea anyone is talking about 2 or 3 in wall plates? If you see my original post, you will see it shows the joust size as 8in and the wall plate is drawn the same size.

Do lintel makers say this too? Or do they specify a certain distance [of set] masonry before joists are laid? Asking for a friend.

For the lintel with no top lip (Catnic CG-type) they recommend one full block course on the inner leaf below the floor joists; for the welded-type with a top overhang,(HD-type) there is no recommendation and the inference is that you can seat the floor joists direct on top of the lintel, but they say that there must be a block bedded into the back of the lintel before loading with joists and blockwork above.
This is why I was dubious about the OP just wanting to bed a timber plate there instead of blockwork.

I probably thought wall plates were 2 or 3" because that's what they are.

What you described is not a plate. My apologies for your confusion.

...wallplate .... bolted to the blockwork

Basic wrong terminology, but no need to be sorry I'm sure you know what meant.

What are you on about?
When talking joists and ceilings and floors, a wallplate is a wallplate and frankly i've never seen one smaller than 4 inches.
2 or 3 inches is for dolls house

Have you ever been on a building site???

 

[johnny2007]

Out of curiosity i looked at google images about wallplates.
One of the first ones identifies the wallplate as a "ledger".
LEDGER???
Who the heell calls a wallplate a ledger?
Someone googling things or someone who spent decades on building sites?
I see what you were looking at.
That's a different wallplate used for finished walls, lofts, garages etc.

I figured making it as simple as possible with colour coded pictures was sufficient for everyone to understand. Clearly there is always one

It was clear.

AFAIK Americans and structural engineers these days..... Seeing the term used more and more in architects detail drawings, too. Maybe they are doing it to differentiate with the wall plates fitted to the top of masonry walls (strapped-down) onto which truss frames (roofing) can be built?

I think there's maybe some confusion over sizing terminology here - I presume that by 2in wall plates (or ledgers) what is meant is 2in thick..... I've installed 2in thick ledgers (actually 10 x 2in section) where the joists were 3in thick (10 x 3in section) on a few building refurbs

No confusion:
I attach the op's initial image: the yellow piece of wood is called wallplate in all building sites in England.
If you are a google builder you will call it a ledger.

 

[Deleted member 174758]

Obviously the S/Es we work with (from firms like Arup) aren't proper construction people at all.....

Personally I don't give a hoot what they call it, so long as the drawings are clear

No it isn't, I would call it a timber bearer. The timbers on top of walls that roof trusses sit on are usually what is meant by wallplates on all building sites in England
ps just looked back at the original picture and noticed it is described as a timber bearer on there .

As well as.
As already mentioned.
