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.
