Dowel holders as welded and canted support cages made of wire rod S 235 JR (Ø 5 mm) are use to ensure dowels in a transverse joint keep their required position during construction.
The following details are needed for costing and production:
- Joint type (contraction or expansion joint)
- Pavement thickness (height of the concrete)
- Dowel spacing
- Holder length; whereby the maximum production length is 4.0 m;
2 – Piece dowel holders are made for larger working widths.
Example of support on both sides in expansion joint (expansion joint filler of drilled softwood board).
Expansion compensating sleeves (inside Ø 26 mm and 80 mm long) made of plastic which ensure an expansion space of approx. 15 – 20 mm are pushed onto alternating sides.
Bituminised wood fibre soft board (soft fibre panels) can be supplied as expansion joint filler between the two dowel holders.
