Stepped Parabolic Corner
For this project, IG Engineer – Kyle Alexander designed a stepped corner lintel with a parabolic arch to suspend over 1 tonne of stone from the outer steel shelf. The lintel was designed to ensure that no steelwork was visible.
This system works by drilling holes into the outer steel shelf. Expansion plugs are then placed into the hanging sandstone and are bolted from above through the holes in the steel shelf. In addition to supporting the load of the hanging stone, the fully insulated lintel carries a 500mm wide wall structure above.
Spanning 7 metres along the front face and returning a further 3 metres at the corner, this special lintel is a prime example of how IG lintels can adapt to the client’s brief.
