TCC MAX

TCC MAX is an innovative type of connector for creating composite action between timber and concrete in a structural element such as a beam or slab. In this technique, both materials work together with their best strengths, concrete in compression and timber in tension.

It comprises of a steel cylinder fixed to the timber member with six 6,5 mm x 100 mm KonstruX fully threaded screws around its perimeter, and one M14 x 60 mm 8.8 bolt inserted above anchoring in the concrete member. The screws bring withdrawal resistance and high initial stiffness. The upper bolt and cylindrical part contribute with bearing strength.

Timber-Concrete Composite (TCC) elements are ideal for new projects comprising big structural grid sizes while maintaining a slender slab. Moreover, TCC can be exploited in antique timber buildings with wooden beams needing reinforcement, or when a change of use requires improved strength and stiffness.
