Abstract: The invention is a reinforcement unit for reinforcing a footing element by laying a pile foundation with a foundation pile with at least one through-going longitudinal cavity and a method for placing the foundation pile and reinforcing a footing element with the reinforcement unit. The reinforcement unit includes at least one shaped and articulated reinforcement member that is pivotably connected to a centrally arranged, annular element, so that the reinforcement unit has a folded mounting position and an extended position of use, and is connected to the foundation pile by one or more tension members.

Abstract: A spacing member for chocking reinforcement wires in a certain level from the outside of a finished cast structure. The spacing member comprises a first spacing chock (1), a second spacing chock (21) and locking clips (14, 42). Reinforcement wires are placed in supporting surfaces (7, 8, 9, 10, 24, 25, 26, 27) in the spacing chocks (1, 21) and, by using several different spacing chocks, it is possible to place reinforcement wires in several different levels. In particular, the combination of the first and the second spacing chock provides the possibility of placing several crossing reinforcement wires in several levels.
