The structure has three peripheral rods (2-4) symmetrically placed with respect to a central rod (1). A spacer (5) holds the rods (1-4) along an appropriate spacing to exert a force in a horizontal direction on the rods for tensioning the rods. The rods (2-4) are adapted in flexible profiles. The spacer has a set of teeth with pins that allow the integration of a centering ring on the rods. An independent claim is also included for a method of fabricating a stake forming structure.
