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 100 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.
