Solid-bar piles
In contrast to hollow-bar piles, solid-bar piles need to be installed in a supported borehole. They have a high load transfer capacity with a small borehole diameter due to the high-strength threaded rods that form the load-bearing element.
Structure
Solid-bar piles consist of three main components:
- Pile head
- Steel tendon or compression member
- Grout body
The steel tension or compression member is a round bar with hot-rolled coarse thread ribs and can therefore be cut or coupled at any point.
Features
- Nationally and internationally approved system with internal and external quality control
- Good adaptability to transport and assembly conditions, thanks to delivery in sections with couplers
- Easy to adjust to the required length on site, e.g. for varying geological conditions, by using sections with couplers
- Excellent bond between the threaded rod and cement mortar thanks to the use of thread ribs
- Easy to adapt to the required loads thanks to a wide range of cross-sections
- Transfer of tensile, pressure and alternating loads
Structural variants
– Short-term pile for temporary use – standard corrosion protection (SCP)
– Short-term pile with extended temporary corrosion protection (ETCP) – standard corrosion protection with abrasion rates or coatings (galvanisation)
– Permanent pile with double corrosion protection (DCP)
