The easiest way to fixing stairs and landings

The Architect gains a smooth obstacle-free soffit with no supports on show

The Engineer gains a robust, simple and efficient connection, which can also be used to satisfy robustness

The Insitu Contractor does not need to incorporate connections into the wall requiring tight tolerance

The Precaster keeps control of the connection within the factory, with no need for specialist operations on site

The Main Contractor gains reduced crane hook-time requirements, and rapid provision of access stairs

Advantages with IC stair connectors

Corbel-free connection between staircase and landing.

• Sustaiable
• Cost effective solution
• Faster and safer installation on site, see stair film “installation”
• Reduced crane time
• No welding or bolting on site
• Impact sound insulation
• ETA approved/CE market product
• Design tools / drawings 2D 3D
• Tested for seismic areas
• Invisible

Guidance to IC Stair Connections

See: Memo 31

What are the requirements for the stairs?

Surface, Terrasso, see below
Soundreduction, see Memo 47
Fire, see side 9 and Memo 45

TSS or RVK

TSS – (Terrasso Stair Support).

Inner tubes are pulled out with wire and return rope (no visible marks on the surface, suitable for terrace surfaces).

RVK – (Repos Vegg Konsollfritt (Repos Wall Consoll free)).

Inner tubes are pushed out by hand / tools from top of repos (casting visible in surface)

TSS for landing/wall

Connections for stair flight to landing.

Artikkel nr	Beskrivelse	Kapasitet	Bilde
TSS 20 FA	Stairflight to landing connector with adjustment.	20 kN
TSS 25 L	Stair flight to landing connctor with adjustment and lifting device.	25 kN
TSS 60 P	Slim design allows thinner slabs all the way down to ≥120 mm (full capacity 170 mm). Outer sleeve made of recycled HDPE.	57 kN

TSS 25 L

Lift of element under production.
Treads for wire loop lift during installation at site.
Stepless height adjustment during installation.
Saves stair nosing’s.
Efficient installation on construction site, avoids shimming.
No need for local reinforcement.

For more information, see memo 65 A.

TSS 20 FA

Stepless height adjustment.
Saves stair nosing’s..
Efficient installation on construction site, avoids shimming.

For more information see: Memo 65 A

TSS 60 P

Can be used as connector stair flight to landing.

Which model and capacity to choose ?

Our bespoken calculation tool helps you to find correct model.

Tip! 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

Fire protection

See Memo 45 and IC Academy for correct installation.

Fire protection is taken care of in a good way when using IC star connectors.
After installation the TSS/RVK will be completely covered with concrete.

Fire rating in accordance with Eurocode

Required fire resistance	R30	R60	R90	R120
Minimum cover «C» mm0	0	25	30	60

Impact sound insulation

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 22-28 dB

TSS/RVK with IC-Box SRU, reduce impact sound by 8-23 dB

TSS/RVK with vertical rubber flange, reduce sound impact by 10-12 dB

Slab thickness and edge distances
