Fastening Noise Barriers Deutsche Bahn
TOGE TSM BC SB L
Fastening of noise barriers
on Deutsche Bahn structures
- Authorized Approval
- Low edge distances
- Force Transmission
- Installation
Approval of the Federal Railway Authority for alternating fatigue loading up to 5 million load cycles as defined in DB Ril 804.
Approved for outdoor use with a service life of 50 years.
Low edge distances allow noise barrier uprights to be anchored to narrow components while simultaneously absorbing high forces.
Transfer of fatigue-relevant actions even with installation-related inclination of the anchors up to 3°.
Transmission of transverse forces even when loaded in the lever arm.
Transmission of forces in the existing concrete by the undercutting technique in combination with bonded mortar.
Fast and secure installation.

Approvals
General design type approval + general technical approval Z-21.1.1799
Federal Railway Authority approval 213.3-213izbia/009-2101#020
Federal Railway Authority approval 213.3-213izbia/011-2101#005
Base Materials
Application in cracked and non-cracked concrete
of strength classes from C20/25 to C50/60.
How easy the installation works:
- Drill a hole at right angles to the base plate.
- Thoroughly blow out the drill hole.
- Brush the drill hole 4x.
- Thoroughly clean the drill hole again.
- Discard three full strokes of composite mortar – then inject composite mortar.
- Screw in concrete screw.
- After reaching the screw-in depth, the composite mortar must emerge at the concrete surface.
- Hand-tighten the tensioning nut against the concrete. Screw on adjusting nut and place elastomer washer.
- Position the post.
- Build formwork.
- Shim base plate with suitable mortar (max. shim height 40mm).
- Fill the annular gap between the screw anchor and the hole in the base plate.
- Place the NLX wedge lock washer with the bulge facing downwards, screw on the locking nut and apply torque. The torque must be applied in two stages:
Stage 1: 70% of the tightening torque
Stage 2: 100% of the tightening torque
