The bricks (1) arranged in line to form the beam are reciprocally joined by at least one reinforcement rod (2). This is fixed in a length (3) of binder located in upwardly open tracks (4) in each brick. The reinforcement (2) is of the dual or multi-steel type in which at least two longitudinal rod or wire components (7,8) engage in multiple, transversal components (9) joining longitudinal constituents with one another. |
