End Connections
DESCRIPTION
Tie rods are connected to earth retaining structures using a wide range of end connection details to suit varying materials and design conditions.
Item | Image | Key Features |
---|---|---|
Threaded end with hexagonal nut and bearing plate | ![]() |
Simple cost effective connection to flat concrete or steel surfaces where articulation is not required. |
Threaded end with hexagonal nut and AZ bridging plate | ![]() |
As above, modified bearing plate accommodates the sheet piling interlock on the inside face of an AZ pile |
Threaded end with hexagonal nut and wedge plate / tapered washer | ![]() |
As above, provides simple compensation of inclined anchorage |
Threaded end with spherical nut | ![]() |
Simple cost effective connection to flat concrete or steel surfaces providing 7º of rotation/articulation in all directions particularly suitable where settlement is likely Accommodates the above plate options as required. Plates require machining of a spherical seat or an additional plate/washer with spherical seat |
Eye tie rod – direct waler connection | ![]() |
Simple connection to waler beam allowing horizontal rotation. Suitable where there is a requirement for variable tie rod connections at different or unknown angles Allows for quick and easy connection |
Eye tie rod – cardan joint waler connection | ![]() |
Simple connection to waler providing articulation in the vertical plane ideal for situations where settlement is predicted in combination with a waler fixed to the rear face of the retaining wall Allows for quick and easy connection |
Eye tie rod – T connection | ![]() |
Purpose fabricated T piece designed and certified for load transfer between the tie rod and HZ King pile, e.g. at corner sections or non-parallel walls Allows for quick and easy connection – typically not suitable for use with tubular piles |
Eye tie rod – T connection for concrete embedment | ![]() |
Purpose fabricated extended T pieces with bearing plate, primarily used for connection of eye tie rod to concrete-filled tubular King pile or concrete capping beam |
Short threaded eye tie rod for concrete embedment | ![]() |
Threaded end provided with hex nut and bearing plate for encasement in concrete, placed to provide a full hinged joint connection Designed to consider bending moment in the protruding bar section of the tie rod |
Spherical head connection | Spherical head diagram from AS powerpoint wide range of connections![]() |
Ideally suited for concrete capping beams (allows continuous formwork) and tubular piles with concrete infill |
