(54) Sound-resistant and sound-absorbent noise barrier


(57) Sound-resistant and sound-absorbent noise barrier 101 constituted by in plant preassembled modules 1.0 Each module comprises panels 2 in "Porenbenton" overlapped on each other by means of tie bars 17 fitted to a supporting base. The panels are then packed to each other realizing the module 1 that is transportable for the laying in loco.
Each panel 2 constituting the module, has two slots 4' in correspondence to the lateral faces within which rest two supporting vertical posts 4 that support each module. The slot is such that, preferably, the post is hidden inside of it.
Moreover a solidifying fuid casting 10, allows the creation of a groove-and-tongue profile that makes easy and functional the lateral coupling between a module and another one during the laying of the barrier. Moreover there are no visible supporting elements that interrupt the continuity of the same barrier.
A combination of horizontal 50 and vertical 60 holes can be realized on the barrier to improve its soundproofing and sound damping features.
