![]() ![]() To eliminate any potential concerns over safety, each of the 12 anchors connecting the support structure to the concrete ceiling was pull-tested at 500 lbs: HDI-P Loads–Normal-Weight Concrete and Hollow Core Concrete Panels Each anchor features a lip to ensure flush installation, consistent anchor depth, and easy rod alignment. The Hilti-HDI-P is an internally threaded, flush mounted expansion anchor designed for solid and core panels, precast plank, and post tensioned slabs. We don’t come across hollow core concrete panels in hospital settings often, but when we do, we recommend Hilti HDI-P drop-in anchors. One suggested option-reinforcing each hollow section panel with liquid grout-wasn’t feasible because the process would have taken 2-3 weeks and put the GC behind schedule and over budget. In this case, our GC had concerns over securing 1,000 pounds of x-ray equipment to a hollow core panel style ceiling with traditional concrete anchors, per his supplied drawings. The low-cost, hollow core concrete ceiling sections commonly used in office building construction can create significant design challenges in hospital settings. ![]()
