I will attach roof beams for a mono-pitched roof to cement hollow blocks and am considering different solutions. Drilling through the hollow blocks and attaching on the other side does not work for me. What can I do?
I've looked at using a perforated sleeve with anchor mortar, but the downside is that the anchor mortar will disappear into the air holes of the hollow blocks. I've also considered chiseling suitable areas in the hollow blocks, filling with cement, and attaching the roof beams with expanding bolts.
I will use construction timber C24 45x220. The span is 4000mm, the roof pitch is 18 degrees, and with a center-to-center distance of 60cm, I need to have 9 roof beams. It will be a sheet metal roof with insulation and interior cladding; 0.4 kN/m2.
The next question is what dimension I need for bolts, threaded rods, or whatever is used.
Grateful for tips and ideas.

One variant is to use a wall plate that is attached at even intervals with embedded metal straps. Then attach the roof beams to the wall plate with joist hangers or angle brackets.
