GEWI® Threadbar System
For couplers exposed to compression load, predominately in geotechnical applications, lock nuts can be omitted.
However, it is important that the two threadbars meet centrally within the coupler, and remain so during installation, to ensure the correct load transfer.
This can be achieved through the use of grub screws and a center pin. The right position of the GEWI® Threadbars within the coupler can be checked easily using colored marks.
Anchorages for GEWI® Threadbars
Anchorages which are to be embedded in concrete can be installed using an anchor nut (hexagonal nut), a steel plate and a lock nut. In addition, an anchorage can be realized using a flanged nut and a lock nut.
For the connection of GEWI® Threadbars with steel structures, a weldable anchor piece is available.
