TECNARIA produces connectors for the reinforcement of composite wood-concrete, steel- concrete and concrete-concrete floors.  Connected structures are used more and more, both for the reinforcement of existing floors, and the construction of new floors with better characteristics.  The connectors have been tested in accordance with the latest European regulations.  The company also provides extensive support to designers.
The first connectors were designed for composite steel-concrete structures in 1989 and tested at the University of Padua (Italy) in collaboration with Eng. Giorgio Romaro. The CTF connector was launched on the market in 1992. It was originally conceived for making new floors with profiled sheeting, but also became widely used for the restoring and strengthening of existing floors. During the early Nineties, the construction market had begun to show a great interest in innovative techniques for restoration and consolidation.

In the mid Nineties, solutions were called for the restoration of wood floors which, as with steel floors, presented all the characteristics of effectiveness, simple installation and guaranteed results.

Wood floor connectors
Studies and prototypes of the connectors for wood floors CTL BASE (1994) and CTL MAXI (2002).

The CTL connector for composite wood-concrete floors was born from the idea of adapting and slightly modifying the same connector that was used for steel structures that had already found favour on the market. It proved to be a success. The base plate was reinterpreted with crampons that penetrated the wood and, instead of nails, screws were used for fixing. The first “BASE” connector appeared in 1994. Its evolution, the “MAXI”, arrived 8 years later.
