Tie bar holders for threaded tie bars in longitudinal compression joints

Tie bar holders as welded and canted support cages made of wire rod S 235 JR (diameter Ø 5 mm) are use to ensure tie bars in a longitudinal contraction joint keep their required position during construction. They are produced as narrow holders.

This version is used to keep the threaded tie bar coupling (half threaded tie bar) in position in a longitudinal compression joint.

A narrow support cage only is required here. Here too, individual support is advisable if the threaded tie bar spacing is irregular or very large.

The following details are needed for costing and production:

• Joint type (contraction or compression joint)
• Pavement thickness (height of the concrete)
• Tie bar spacing
• Holder length; whereby the maximum production length is 4.0 m;
  2 – piece tie bar holders are made for larger working widths.
