In my project, MEP wanted to hang their stuff from the composite deck (3" concrete over 3" deck) using Hilti anchors, cast-in-place and/or post installed. The deck will be drilled a hole so the anchor get into the slab concrete above 3/4" or more. The maximum point load reached 500 lbs. I am not sure if it is acceptable. Hilti does have a table for their anchor capacity. But I don't know if I can use that. Vulcraft don't have too much information on that. Does anybody have an experience on this? Can yon please give me some advice? Thank you very much!
