Bridge Cap Anchor DB for subsequent fastening
Bridge Cap Anchor
TOGE TSM BC SB VS
For existing or prefabricated caps of DB bridges or subsequent fastening
The TOGE TSM BC SB VS bridge cap anchor is approved by the German Federal Railway Authority for alternating fatigue loads up to 5 million load cycles in accordance with DB Ril 804. In combination with injection mortar, it allows high load absorption in cracked and non-cracked concrete. The composite mortar seals the borehole during application, preventing water penetration. This TOGE bridge cap anchor is approved for concrete strength classes from C20/25 to C50/60.

This is how simple the installation works:
- Create hole with 45 mm diameter.
- See 1.
- Create a 65 mm diameter hole concentric to the 45 mm hole.
- see 3.
- Drill a 22 mm hole concentrically to the 45 mm hole.
- Thoroughly blow out the drill hole.
- Brush the borehole 4x.
- Thoroughly clean the 22 mm drill hole again.
- Discard three full strokes of composite mortar – then inject composite mortar into 22 hole.
- Screw the concrete screw into the 22 mm drill hole.
- Brace backfill disc against edges of 65 hole using nut, fill 45 hole over backfill disc with composite mortar and grout 65 hole with suitable compound mortar.
