Beam to stud connection detail (typical)

[kaspor]

Hello

I have a 250x90PFC and a 300x90PFC that will be supported by 3x90x45 F17 KDHW tripple studs either side. The beams are used on brick veneer walls in a residential home to support upstairs internal framing and bricks.

A 200mm flat plate will be welded underneath the beams which will support bricks on the external side of the wall. The plate will protrude outward from the internal wall to the external

Does anyone have a typical connection detail for how to secure this beam onto the studs?

Greek, or maybe UK... do you maybe have a sketch?

More likely AU, dik.

I was going to reply to that, but likely inflammatory... I suspect the 250x90PFC is an 'I' type section, but have no clue about the 3x90x45 F17 KDHW, unless 1/8" thick.

Sorry - yes this is Australia. Here's my attempt at a sketch!

I'll be welding either a flat plate or UA angle to the opposite side of the beam to support brick work. The view is from internal.

Are the studs and the beams 'cold formed sections? Can you put a 'track' section on the triple studs to give a flat bearing surface. Can something be strapped to the three studs and track to the side of the beam? Can the connections be done with self tapping screws? ...like TEKS? What is the magnitude of the loading? Is the load from the brick eccentric? Can you do a cross-section?

I believe the PFC is hot formed not cold formed. The studs are just hardwood studs. I was thinking of welding a plate onto the back of the PFC (say half way up) with a 6mm CFW, then punching some holes in the plate and screwing that into the front of the studs.

In these environs, most wood stud material is softwood (conifer not deciduous). Can you make a steel inverted bent 'U', with a couple of welded threaded studs attached. Secure the U with screws and bolt the beam to the threaded studs?

PFC = Parallel Flange Channel

KD = Kiln Dried; HW = Hardwood; (not sure what F 17 means):

BART: I know you can get hardwood lumber... most material in Canada, for construction is softwood lumber.

If a channel, you can have a plate welded to the top and the connection can be bolted...

Thanks for the response.

A U-shaped bracket won't work, as I can only bolt to the hardwood studs on one side. It will interfere with plaster on the other side.

It would have to be an L-shaped bracket, but then it's lifting the height of the beam which I don't want to do (currently my window fits snug underneath it).

I don't really want to drill anything through the top of the studs as they will split.

Use lag screws or SDS fasteners from one side? or an L shaped bracket.
