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 f

cmin

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 f

cmin

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.
