<p>The present disclosure relates to a combination assembly for casting and post tensioning of, and subsequent fixing of an external system to, a concrete structure, comprising, one or more tendon units adapted for post-tensioning of the concrete structure, each of the one or more tendon units comprising one or more strands, and a sheath adapted to receive the one or more strands therein; a channel adapted to be cast into an edge of the concrete structure, the channel comprising a partial luminal wall defining a longitudinal cavity within, and one or more slots adapted to receive the one or more strands therein; an anchor block being co operable with the channel, the anchor block having one or more through bores adapted to receive the one or more strands therein and permit sliding translation of the one or more strands perpendicular to the longitudinal axis of the channel, allowing the one or more strands to be tensioned relative to the channel; one or more locks adapted to lock the positions of the one or more strands relative to the anchor block, and thus the channel, in a tensioned configuration, and to allow adjustment of the one or more strands in a released configuration; and an external load transfer element being co-operable with the channel, the external load transfer element being connected to the external system, in use. */ // / / / / N j j !
