Soundabsorbing and/or soundproofing sectional module (10) for a soundproofing wall (11) comprising at least two modular panels (13) coupled together in a co-planar manner. Each modular panel (13) comprises a first external sheet (19) made of ductile material, a second external sheet (20) made of ductile material, and a middle layer (21), interposed between the first external sheet (19) and the second external sheet (20), and made of soundabsorbing and/or soundproofing material. The first external sheet (19) and the second external sheet (20) comprise respective first peripheral portions (15) reciprocally shaped so as to define at least a first coupling edge (13a), which is coupled with a corresponding second coupling edge (13b) of an adjacent modular panel (13), in order to form a connection joint (17) between the modular panels (13), at least the first peripheral portion (15) of the first external sheet (19) comprises an end bent with respect to the first coupling edge (13a) so as to form a first longitudinal rib (22), while the first peripheral portion (15) of the second external sheet (20) has an end bent over the first longitudinal rib (22) in order to form a first gripping loop (23). |
