Abstract
The prefabricated noise-damping wall comprises at least one wall component to be supported between uprights. The wall component is composed of a number of parallel sections with distance and stiffening fillets arranged vertically across the surface in paired formation. Adjacent the outer ends of the pairs of fillets, planks (7) forming the top and bottom wall limits are provided with a retention groove in which metal T-shaped union pieces (12) are fitted. Flat cross legs (13) fit against the outside of the planks, and lengthways legs (11) are located between the fillet outer ends, being connected to them by bolts (14).
