NOTE
(1) Two-level tromplate.
(2) All the tromplates used are relevant to type A D, without steel tube, sheath coupling or internal HDPE trumpet.
(3) Dimensions depending on the type of steel. The standard model corresponds to D2 and H2; the other models are only fabricated on special request.
(4) The helical or cross-wise bursting reinforcing bars given in the table, which oppose the bursting force in the concrete of the anchorage zone, are only valid for an isolated ancho-
rage in a prismatic section piece (test block), for concrete with a strength fcmin between 20 and 40 MPa (cylinder strength).
 When the anchorages are grouped into one of several lines, continuous reinforcement with an equivalent cross-sectional area must be provided to link all the anchorages, appro-
priately anchored within the structure. Kindly refer to System C technical data.
 For concretes with a strength fcmin between 40 and 70 MPa (cylinder strength), kindly refer to System C technical data.
(5) The types of jack which are framed correspond to optimal use. The other types are meant for optional use.
