Steel column in foundation wall; Ties? Concrete?

[eros_poli]

Hi everyone 👋

 

I'm trying to detail an element of our build and need a hand. 

 

This is a timber frame construction, coming off a 140mm block wall on strip foundations. 

 

Within the wall on the gable ends are two 152x152 UC30 columns, fixed to the founds, running through the height of the block wall, up through the timber frame to the ridge. 

 

The block-work is 140mm. If my maths is correct, those blocks won't neatly slot into the open side of the UCs. 

 

So, how best to tie these blocks to the columns? I can't seem to find a supplier of the relevant Ancon ties (Non-Standard Internal Column Tie or Hammer on Tie).

 

Could I use a more standard tie, which sits within the void of the UC, then fill the void of the steel with concrete, to the depth of DPC/top of the foundation wall? This would help with thermal mass too... 

 

I've attached a section of one wall, the the steel oriented as designed by the engineer. Pretty sure the blocks won't fit inside the opening (138.8mm)

 

Any advice welcome!

 

Joe

I'd trim the ends of the block sides so you can sit then fully in the steel and then tie into the web.

We fixed wall starter kits into our web (using self tapping screws) and then the ties just slot into that at each course.

Hasn't your SE provided any detail for this?

Good idea trimming the blocks so they nest easier. 
And no, SE hasn’t specified this detail.
