Trapphus veiledning

The most efficient, economic and sustainable way to connect concrete stairs and landings.


Cost-saving:

  • Thinner landings (20-25% reduce concert consumption)
  • Documented and certified solution
  • Fast installation
  • No need for shimming, leveling adjustment
  • No extra lifting point on the stair flight needed
  • Good tolerances
  • Fire protection
  • Safe to install
  • Access stairs in the building process


Requirements for the stairs:

  • Surface, Terazzo, see TSS
  • Impact sound reduction see Memo no 47
  • Fire protection, see page 9 memo 31 and Memo no 45

Difference between TSS or RVK

TSS – Terrazzo Stair Support

Inner tube pulled out with a wire and return rope. No visual marks in the surface of the landing.

RVK – Repos Vegg Konsollfritt

Inner tube is pushed through a slot in the surface of the staircase. The slot will be visible on the surface and has to be grouted.
Sound transmission / Fire protection


IC deliver several solutions for impact sound insulation, see Memo 47 and IC Academy film stair engineer.

TSS102 with vertical rubber flange,
reduce sound impact by 20-25 dB.
TSS/RVK with IC Box 100 SRU,
reduce impact sound by 20-28 dB.
TSS/RVK with vertical rubber flange,
reduce sound impact by 10-12 dB.
Fire protection is taken care of in a good way when using IC stair connectors.
After installation the TSS/RVK will be completely covered with concrete.

Which model and capacity to choose ?

Our calculation tool helps you to find the correct model

Calculations tool TSS-RVK

Ideas! TSS/RVK should be located as close to the front edge as

possible to avoid uplift/negative forces in the rear end of the element.




Reinforcement of stair connectors TSS/RVK landing-wall
Standardized local reinforcement for TSS/RVK,
see Memo 55, TSS / RVK, reinforcement
TSS 25 L, see Memo 65A
TSS25L no need for additional local reinforcement,
the backplate and flat steel is enough.

1) The TSS102 may in special cases fit into slabs with t=200mm if reduced concrete cover is acceptable. The unit should be placed centric in the slab, which will slightly reduce the height x8 below the minimum value stated in Table.
