ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to a protective barrier which can also be employed as cladding for walls or as cladding for the footing of buildings.
Nowadays it is known to provide protective barriers which are arranged next to roads or railroads and are used in particular to reduce the transmission of noise or to prevent any mutual dazzling occurring between cars traveling in opposite directions.
These conventional protective barriers are usually constituted by a footing which is usually buried in the ground and supports a frame between which for example suitable flat panels are arranged. Such panels can be internally empty, in order to prevent only the passage of light, or can be internally provided with sound-deadening material and with a finely perforated panel surface so as to reduce noise transmission.
However, these conventional protective barriers are substantially of the passive type and are used exclusively, and to a limited extent, in order to provide barriers to light or provide partial noise absorption, as above-mentioned, whereas the problem of atmospheric pollution is much more strongly felt, especially along roads.
SUMMARY OF THE INVENTION
The aim of the present invention is to solve the above-described problem, eliminating the drawbacks of the cited prior art and providing a barrier which can be applied for example alongside roadways or railroads or even optionally along borders or as walls, and which allows to achieve good light shielding, good sound deadening, filtering of dust and/or pollutants present in the air, and protection or decoration.
Within the scope of this aim, an important object of the present invention is to provide a protective barrier which is structurally simple and despite the above-noted air treatment can be regenerated to its optimum conditions rapidly and easily.
A further important object is to provide a protective barrier which associates with the preceding characteristics the possibility of disposing, in a controlled manner, of any absorbed volatile pollutants.
A further important object is to provide a protective barrier which can also be employed as an alternative energy source.
This aim, these objects and others which will become apparent hereinafter are achieved by a protective barrier according to the present invention which comprises a footing which is buried in the ground and supports a frame for supporting one or more panels, characterized in that said one or more panels are internally provided with sound-deadening and/or air-filtering materials, said one or more panels further comprising at least one finely perforated lateral surface, a finely perforated upper surface for collecting water and a finely perforated bottom.
