We have had a beam put in, but it does not look to me like the wall above is fully supported. The house has breeze block construction downstairs, and timber upstairs. This is a detached house. In this picture I am looking up from under the beam. The joists are on the beam, and then you can see the wall plate that rests on the ends of the joists. Is that right? How can the wall plate not be fully supported?
Joists could have all been cut the right length, apart from that the small wall above doesn't look load bearing so shouldn't be a problem.
Wallplate? What wallplate? The joists above are roof rafters, surely, and are very likely self-supporting. Unless there's an ashlar wall above that floor? If so, where does this wall actually come up from - could it be from above where the steel beam is located?
I am not in the building trade, so please excuse my mistake and correct/educate me. I thought the bit of wood that runs along, sitting on the ends of the joists is the wallplate. The timber framed exterior wall of the first floor is built on this. The first floor is timber framed. I hope this other photo shows that the joists are not part of a roof.
Sorry, fail to see what the house walls have to do with the steel. The steel itself is sitting on a pad stone which is correct, the rest of it as per photo seem ok.
It looks like the RSJ has been put in too high, In the first picture all the joists / rafters that run at 90 degrees to the RSJ have been notched to fit over the RSJ.
You have a padstone,couldn't really put rsj any lower, otherwise you will end up below top of opening to your left.
I'm still struggling to understand this The sloping rafters to the left of the RSJ - is that chust a wee extension roof on the main house, or does it continue upwards to a ridge above the main house? That low 'wall' immediately above the joists wot are sitting on the RSJ - what's on the other side? Is it a room? Does that wall support the sloping roof rafters - is there a purlin there where there's that flat timber which I presume is what you call a wallplate? How far do these sloping roof rafters go?
At the moment the RSJ on the right is above the lintel in the opening on the left. Under the lintel on the left the builder has put in some slips to raise the lintel up - the bond looks mismatched in the corner above. Without the drawings it is difficult to see what the architect had planned but would have thought the padstone would have been lower to avoid cutting the timber joists
I realise that I have not done a good job of describing this, and the photos don't show everything. I hope this drawing helps to show the structure above the beam. Thank you everyone for your input! The project is a double storey extension, where the ground floor that projects a bit further than upstairs. The height of the beam is another issue all together which we aren't happy with. It will only be 2.2m, which isn't much higher than a door frame. The sloping roof you see to the left of the beam in the photo is a sloping roof for the ground floor extension. It stops when it joins the house. There is a bedroom above this beam. I hope the drawing answers your question?
I would get a structural engineer to have a look. That is quite a lot of loading coming through that block wall. I am surprised there is no pier at the corner
