Cap beams are a variant of top-hat beams
Cap beams (also called THQa beams) are a variant of the top-hat beams. The construction consists of four parts: two vertical body plates are mounted on a wide bottom plate that projects to one side. A thicker top plate is welded between these body plates.
Cap beams are mainly used when installing prefabricated floor panels at the edge of a building structure.
Top-hat beams absorb horizontal forces
As with top-hat beams, an additional feature of the cap beam is that it absorbs horizontal forces in a steel skeleton well when subjected to wind loads.
If there is good cohesion between the hollow-core slabs, the entire floor acts as a disc and the forces can be dissipated in wind bracing.
The main advantages of cap beams are:
- Low building height
- More pipe space thanks to low floor height
- Versatile and lightweight application in many suspension structures
- Low design costs
- Quick and easy installation
- Easy fire-resistant preservation
All cap beams produced by Composite Steel Beams are made from S355 structural steel (normalized rolling). This type of steel has a higher strength, but is not more expensive than other types.
