[origin: WO2014191648A1] Reinforcing rod with high adherence for reinforced concrete The reinforcing rod (2) according to the invention comprises an extension portion (3) including, on its outer surfaces, catching asperities (6, 7) intended to promote adherence between the reinforcing rod and the concrete, and an upset end portion (4) provided with a threading (8) intended to cooperate with a tapping arranged in a connecting sleeve, the thread bottom diameter of the threading (8) being larger than the nominal diameter of the reinforcing rod. The upset end portion (4) includes a substantially cylindrical first part (41), and at least one second part (42) positioned between the first part and the extension portion, the second part (41) having a general section decreasing toward the extension portion and having a length greater than or equal to the length of the first part (41).
