Hi,
I've been trying to get a fixing to hollow brickwork to work for only 5kN shear force. It's for a mullion connecting to 140thk hollow concrete brickwork to prevent some lateral movement.
I used HY270 chemanchor with sieve sleeve with 85mm length insert; setup with hollow normal weight concrete brick (200 x 200 x 500 as the minimum size) with 10MPa brick strength and M10-M20 joint strength as the max strength I can use. I end up using 4 anchors but HILTI PROFIS ENGINEERING is still failing for 170+% brick edge failure.
From an old catalogue, an HY20 +M12 will provide 3kN capacity in shear, so I'd assume 2 HY270 anchors would work. But 4 anchors still couldn't work which was out of our expectation. I've spoke to Kanan just after lunch, but he's out of the office. It would be much appreciated if you would please help looking into this issue.
Please feel free to call me on 0405 682 312 for further discussion.
Thanks,
Ola Yi
