I am looking for a solution for mounting a shelf that holds a pressure sprayer to precast Concrete panel with a Foam core insulation sandwiched in the middle. total weight to support is 300 pounds, The shelf has 6 holes to mount with located in 2 rows of 3. The panel is 8 inch total (3 inches then 2-inch foam panel then 3 inches). ( diameter of holes in Shelf is 1/2 inch so I think 3/8 inch anchors are appropriate. If anyone could send a link to a product that would be great. Engineering data / Submittal type info would be very helpful as well. I need to validate that the ANchors are appropriate for precast concrete. Thanks in advance!
This is a situation that should be reviewed by a structural engineer. More about preventing damage to the panel then about support of the item.
For anchor information, check out Simpson Mechanical Anchors. The Titen HD is a common choice
