Product launch at Invisible Connections AS

Invisible Connections has launched a brand-new ‘’game changing’’ stair and landing connector.
RVK and TSS 60 P are a sustainable connectors for prefabricated concrete stair and landings. We have reduced the amount of steel by more than 50% and the outer tube is made from recycled PE from the local company Plasto AS.
With our new connections you can also lower the landing/stair slab thickness, full capacity 60 kN 170 mm, but can be used all the way down to 120 mm.
Thinner slabs -> less concrete -> lower CO2 emissions.

IC Stair joints in thinner slabs and simplified reinforcement guide

In Invisible Connections, we are constantly working on further development and improvement of our IC products, our TSS / RVK staircase connections has been tested several times before, now we have undertaken a new FE analysis.

Result of this analysis, TSS / RVK can be used in thinner slab with full capacity. The thickness of the slab can be reduced by as much as 20-25% and still has full capacity. This is a good news for the element manufacturer who can use less concrete and the environment as a result of less concrete use.

We have also simplified the reinforcement routing and gathered all the necessary technical information in memos 54 and 55. We hope this will both make the production of the element manufacturer more efficient and make our stair mountings more user-friendly for the designer / RIB.

TSS to the new hospital in Malmö

Skanska chose to use TSS101 for fixing stairs in the new hospital in Malmö, as they achieve efficient, fast and secure mounting of stairs. Element manufacturer is Lithana Group in Lithuania and TSS was supplied by our distributor Semtu.
