Wide Joist Hangers

[MarkWoody]

We are converting our loft and the plans show wooden beams of sizes such as 225x250 and 225x200 made up from multiple timbers (ie. 2@50mm + 2@75mm to make the 250 wide beam) bolted together. This is all OK, however, how do I attatch them to another timber joist or steel joist.

They cant sit on top or in the web/flange of the steel as this would raise the floor too much.

Ideally I'm looking for long leg hangers 250mm wide or narrower hangers which can be butted up to each other.

Does anyone have any ideas?

Try these.

Oh and ask your designer for flitch beam alternatives to those mahoosif beams.

Unfortunately Simpsons Strongtie hangers only have sizes up tp 150mm. We already have planning and building regs approval and the timber is being delivered later this week so changing to a flitch beam is not high on the list at the moment.

I have seen some hangers with internal flanges so they can be butted up to each other. These are made by CULLEN but I don't know where to buy them from. Has anybody used these?

 

[Shytalkz]

Use two hangers for the beams, just bolt right through the timbers close to the supports.

This is stuff your designer should have speccd for you.

Hi,
I would like to use 2 hangers but the Strongties have a minimum gap between them of 100mm because of the outward facing flanges.

Deleted. Wait out.

There is a welded hanger on P2 here, but no real info, so you would have to ring their technical department for loads and widths.

This lot do speshuls.

OK - Thanks for the help and suggestions.

Simpsons do some hangers with concealed flanges (SAI range) which I think should do the job. These can be used alongside each other with no minimum gap.
