If you put that number in as the 'Case Number' at NZ patent search then you should find a couple of pdfs that describe the concept a bit.

As far as I know there hasn't been any specific testing on what they do as a diaphragm load path.

So far I know it's a proprietary product cast into a wall panel to connect hollowcore floors and/or topping slabs.

Attached is the sort of detail I have, and that's about all I can find on google too.

The building I'm assessing already has seating retrofitted, so primarily I need to know if these things provide any additional capacity to transfer diaphragm loads into the wall.
