what lintel over tri fold doors

[nottsrob184]

Hi all.
I need to know what type / spec lintel to bridge a 2.7mtr gap over an opening for the tri-fold door.
It is only single storey which will support only roofing timbers (8x2's) and tiles.
Obviously there will be a couple of rows of bricks over the gap and on the lintel but not decided yet if i will lay as soldiers or horizontal.
Thanks

What is the span of the roof?
Wall makeup (ie 100 block, 50 cav, 102 brick)?

When you say only roof timbers and tiles.. so no ply, no insulation, no ceiling plaster?
Also for tiles you need a fair pitch, so with just 8x2s have you a vaulted ceiling? If so how is the load spread combated?

Are there any unusual loads where the lintel is going, ie doubled up trimmer joists for roof lights or steel beams?

hi

im working on a simillar project. we've used a U-Beam with a 6mm plate welded to it.

off the shelf lintels (catnic, ig, keystone etc...)is not recomended as they dont like you drilling into their lintels.

with regards to the specific UB size you will need to consult the pros.

good luck.

Walls are 102 brick, 100 block internal; with 100 cavity.
From lintel to existing houe is 12 foot and total length of extension is 25ft.
Internal walls will be boarded and skimmed. Ceiling will be 12mm board and skimmed with 6 inch of loft space insulation

Thanks for original reply.

You should end up with something like this, although as mentioned you'll need an engineer to specify the size of the beam.
