The sound barrier includes several noise prevention panels (6) connected via carrier posts (1,2) formed of steel sections having two arms of different lengths defining an angle between them of 90 to 140 deg. The longer arms (1) are anchored and an angle to the weld and the shorter arms also run at an angle to the weld. The longer arms act as a guide section for panels (6) inserted between the posts from above. The shorter arms act to fasten suitable solar panels (5). |
