Universal column timber packer for hanging ceiling and floor joists

[hatcheth]

Hi,

Structural engineer has specified a giant 356 x 368 x 129 UC to support existing back wall for an open plan kitchen / dining room. Also has specified stiffeners at 600mm centres, with bolts at 300mm centres to secure timber into the web.

The problem is that the gap to fill with Timber is approx 290mm x 180mm on each side = Lots of timber at an odd shape.

Any recommendations on what timber sizes to use to pack out the web to hang the joists onto? Would it need to be solid timber the whole way through, our could you partially pack out the depth of the web so the timber is only solid on the face.

Hi,
I'm only a DIY'er, so may not be able to add much, and I may be very wrong!

But the fact that the SE has specified fixings from the wood to the UC, suggests they are integrated structural elements and should be full depth to support the joists (but as you say, that would be massive).

To add to the issue, the root radius of the column will create an even odder shaped piece of wood!

I think a quick call to the SE would help clarify your options

The timber is normally just to fix the hangers to for the joists, and not structural for the beam performance.

So you can pack the timber out, with suitable depth timber for the hangers and timber blocks in the web
