Hünnebeck is the name of a company that supplies formwork, supports and scaffolding. In practice the name is also used to refer to the steel support systems that prop up concrete formwork while the concrete is being poured and cured.
What is it for?
When casting concrete in situ (for example a floor or beam), the formwork must be supported until the concrete has enough strength. For this, props and beams are placed under the formwork:
- Tower prop — a tall, build-up prop for great heights
- Three-legged support — an adjustable support that stands stably on three legs
- Hünnebeck beam — an adjustable steel beam that transfers the load of the formwork to the props
Application
- Concrete construction — shoring and propping floor and beam formwork
- Scaffolding — temporary working platforms and support structures
The support may only be removed (struck) once the concrete has cured sufficiently; striking too early leads to deflection or cracks.
Points of attention
- Calculate the load on the support; fresh concrete is heavy
- Set props on firm, load-bearing ground and secure them against toppling
