Beam and Block with timber frame Detail

[firapara]

Hi Guys,

Does anyone have a detail for: foundation to concrete block, to beam and block, to timber frame wall?

With a normal brick wall it is straightforward, a wall with cavity, beams sit in the internal brickwork. But with the timber frame, I do not need any cavity. Do I just lay concrete block with no cavity and place the beams on top?

Thanks

Good afternoon - brilliant !! I have a similar conundrum and been looking everywhere for an example detail as such! Albeit thicker walls with larsen truss and timber cladding, but otherwise same principle (Passivhaus high performance). May I ask please if by any chance you have typical section (walls and doorways) going the other way. And what happens structurally at sub floor vent positions in relation to the 140mm blocks supporting the load? Are these concrete or maybe 7N aerated? And thank you so much for posting this detail - you may have just cured some of my stress! (we can't have a raft due to ground conditions). .......... kr.......m&m

section through larsen truss

I think the blockwork was 7N dense. The sole plate would just run over the top of any vents through the wall.

Hi

Thanks so much for this detail. Can I ask, if this detail is correct going from foundation to block and beam floor with vents? Also, if there is a way to improve the image as I cannot really see the writing.

Thank you? Sorry if I should be typing this in a new thread and have not.

Hi

I am looking to build a garden room which is on a beam and block floor and a timber framed construction with no cavity, just the cladding. I would love to know how you did the vents for the floor through the blockwork and outside. I cannot find anything online.

The images freddiemercurystwin put up are great but I cannot see how to achieve it.

If you have any advice that would be great. I know this was a long time ago.

There's no cavity on the above details either, they are also just timber frame. The details show the telescopic vent in pink. They exit (in this case) through the insulated cladding. If you have no cladding there then they just exist through the blockwork or brick if your masonry below the timber frame is brick instead. The text reads OK(ish) on a PC, maybe try opening DIYnot on your TV's web browser if you have a smart TV but no PC.

Edit I can read the text OK on my phone too.

Hi

Thanks so much for getting back to me with your advice on using a pc to see the images. It does work but on my phone it isn't clear at all. Sorry if I am being a bit dim, I have not built anything from architects drawing before.

So you build the foundation walls out of 140mm blocks for the block and bean floor and then you build off of the beam and block floor with another block so you can put your insulation and screed into. How do the vents get into the block walls. I am trying to picture it but I just cannot. Sorry.

On the diagram you have the plinth eps which is encapsulated, is this in a render or something.

Thanks again for taking the time to reply.

Regards

Your foundation walls needs to be wider than 140mm, so that you can sit the ends of the beams on the foundation walls, then you have to cut the outer skin of 140 blocks down to get the vents in behind.

The contractor we used is a render specialist who, I'm not sure of the manufacture. If it were me, for a garden room I would have done a suitable brick plinth and not worried about the insulation.

You can get insulation that can be rendered below ground eg https://mikewye.co.uk/product/plinth-board/

Ah I see what you are saying now. So, 140mm blocks, gab then brick plinth and run the vents in that gap.

Thanks for the link also. I am trying to keep the thickness of the walls down as I would lije more internal space. Is the brick plinth included in the total floor area from the architects drawings?

 

[freddiemercurystwin]

Makes sense now? If you're talking about how Building Control consider the floor area then it's the internal floor area so calculate your area up to the inside face of the plasterboard.

Ah wow, that is amazing. Thank you so much. This is very kind of you!
