TCC-II 7,3

TCC-II is a wood-concrete connecting screw suitable for strengthening supporting structures for ceiling slabs when constructing new buildings or undertaking renovation work.
Above all, high payloads with maximum span widths call for high strength, i.e. low deflection of the ceiling structure under load. In terms of usability, wooden joist ceilings push the boundaries of feasibility relatively quickly. Joining wood and reinforced concrete with composite screws effectively exploits the best properties of both materials for a highly resilient structure.
The wood and concrete composite system is used in the construction and renovation of residential and commercial buildings. In new buildings, larger spans can therefore be taken into account in planning at the outset. The strengths of this approach are especially evident in buildings affected by a change of use.
Advantages

• Increased load-bearing capacity
• Greater strength
• Improved soundproofing
• Improved fire resistance
• Existing beams are retained.
• The formwork can be retained.

Material

• Carbon steel
