The hidden cow leg is a steel component designed to support double T-shaped floor slabs on beams without requiring supporting flanges or interlocking mortise and tenon grooves at the slab ends.
During installation, the permanent load—composed of precast concrete components and the cast-in-place composite layer on top—is carried by the concealed cow legs. This load is then transferred from the double T-floor slab to the supporting structure.
Once the cast-in-place composite layer has fully cured, the hidden cow legs and concrete slab work together to share the building’s total load-bearing capacity.
The overall structural capacity results from the combined strength of the concealed leg during installation and the floor slab in the final hardened state.
Advantages
- Simple formwork without the need for interlocking mortise and tenon grooves at beam ends
- Fast and straightforward reinforcement process for steel bars
- Reduced demand for steel bars and concrete
- Lower building height requirements, saving materials and space
- Cost and time savings during construction
- High load-bearing capacity
- Minimal eccentricity (torque) on supporting beams, supporting construction industrialization
- Design tables available to simplify calculations
- No temporary supports needed during installation
- Excellent fire resistance performance
