Cast-in-place washer plate anchors are embedded in fresh concrete with a steel rod and welded plate. They transfer tension through plate bearing and shear via the rod. In this case, shear is transferred via a shear lug.
These are anchors placed in concrete before casting, typically consisting of:
- A steel rod or rebar (often with a thread at the end).
- A washer plate (steel plate) welded or fixed to the rod’s end,
which acts as a mechanical anchorage to transfer tension forces into the concrete.
Advantages
✅Strong load transfer in tension and shear
✅Can handle heavy and dynamic loads
✅Integrated into concrete—no post-installation drilling
✅Precise positioning before casting
✅Reduced risk of corrosion at embedment if properly covered
Limitations
⚠️Must be placed accurately before concrete pour
⚠️Difficult to adjust position afterward
⚠️Requires sufficient concrete cover to prevent splitting
⚠️Not ideal for retrofit applications
⚠️Quality depends on weld and bar fabrication
