Tapping the beam end into the column has been done for 2500 years. This illustration from the Shaanxi History Museum in China dates from about 500 BC, and is an example of invisible beam/column connection with metal strengthening.

Stair Support Inserts

RVK & TSS stair supports

Stair Support Inserts

Quick, clean, hidden connection No exposure to fire Easy to use - speedy erection Cost less than bolted-on RSA supports No bolting or welding No working underneath th elanding TSS requires no making-good to the top surface RVK & TSS have ETA approvals as required by EC2

Why RVK & TSS?

Stair Support Inserts

RVK & TSS

Stair Support Inserts

Clean and clear once fitted. The big advantage for the architect is no visible connections

Stair Support Inserts

The latest solution for connection ofprecast concrete staircases leaves the top surface as finished .

No making good required

Different sizes, covering most situations

TSS 40 = 40 kN TSS 100 =100 kN

Available in plain or galvanized steel
