Definitions

  • the present patent concerns fixed installations for absorbing noise and noise pollution coming from road and/or railway traffic and particularly it concerns a new soundproofing box panel made of FRP composite.
  • Some types of modular panel generally made of metal and/or plastic and containing sound-absorbing material, are also well known. Such panels are relatively easy to install, but do not always meet the needs, particularly as concerns durability.
  • a new type of composite soundproofing box panel has been designed and constructed, whose surface facing the source of noise is covered with suitably-spaced staves.
  • the composite box panel is filled with a layer of sound-absorbing material.
  • the main aim of the new soundproofing panel is to absorb the sound waves generated by vehicles in transit without reflecting them back towards the source of the noise, and without transmitting them to the other side of the panel.
  • the new composite soundproofing panel comprising a box structure whose main face on the traffic side is covered with suitably-spaced staves.
  • Figure 1 shows an axonometric projection of the new panel with a partial cross-section
  • figure 2 shows a vertical cross-section of the same new soundproofing panel.
  • the new soundproofing panel comprises a box structure (S1, S2), a layer of sound-absorbing material (F), spacers (D), and parallel staves (T).
  • the box structure (S1, S2) is constituted by a profiled element (S1), substantially comprising a rear wall (S1a) with two folded edges (S1b) and two generically flat closing elements (S2) situated at either end (S1) so as to obtain a generic parallelepiped lacking one main face.
  • the profiled element (S1) preferably has its three faces (S1a, S1b) with a particular shaping; to be precise, the main face (S1a) is generically corrugated so as to make the profiled element more sturdy, while the two edges (S1b) have concave and/or convex ribbing to allow for the proper coupling of several adjacent profiled elements, or soundproofing panels.
  • the right- and left-hand closing elements (S2) are each composed of a flat part having the same shape as the cross-section of the profiled element (S1), complete with rims lying adjacent to the sides of said profiled element (S1). Moreover, each of the two closing elements (S2) has one or more holes (S2f) to allow for the run-off of any water accumulated inside the soundproofing panel due to condensation or infiltration.
  • staves comprising bands or strips suitable for partially closing this face of the box structure (S1, S2).
  • the staves (T) are arranged parallel to each other in one or more rows and their length and distance between centers are such that they cover from 20% to 80%, but preferably 40%, of the area of the open side of the box structure (S1, S2).
  • These staves (T) are arranged preferably parallel to the length of the profiled element (S1).
  • the staves (T) may have a flat cross-section, an L-shaped cross-section, a U-shaped cross-section, a T-shaped cross-section or, preferably, a T-shaped cross-section in which the horizontal part of the T forms an arch and the vertical part is wider at the bottom end.
  • the staves (T) with a U-shaped cross-section, the staves (T) with a T-shaped cross-section with straight sides, and the staves (T) with an arched T-shaped cross-section are preferably arranged alternately, i.e. so that each stave (T) has its cross section inverted with respect to the two staves (T) on either side.
  • Tongues (S2o) may be provided or created on the profiled element (S1) or on the closing elements (S2) for the purpose of retaining the staves (T) and keeping them correctly oriented.
  • the cavity formed between the profiled element (S1), the closing elements (S2) and the staves (T) is occupied by a layer of soundproofing material (F), preferably made of rock wool or glass wool.
  • This cavity also contains spacers (D) composed of generically flat elements having three sides shaped exactly like the cross-section of the profiled element (S1) and the fourth side shaped with tongues (Do) suitable for holding the staves (T) and keeping them correctly spaced.
  • spacers (D) composed of generically flat elements having three sides shaped exactly like the cross-section of the profiled element (S1) and the fourth side shaped with tongues (Do) suitable for holding the staves (T) and keeping them correctly spaced.
  • the new panel constructed as described above, is installed along the railway and/or road traffic route, orienting the side of the panel fitted with the staves (T) towards the source of the noise and juxtaposing the panels so that the concave and/or convex ribbing of each panel fits exactly into the convex and/or concave ribbing of the panels above and below.
  • the panels can be arranged with the staves (T) oriented at any angle, horizontal or vertical.
  • the new panel constructed as described above, prevents the propagation of noise, absorbing the sound waves instead of reflecting them back towards the source of the sound, and it does not collect any water due to condensation or rainfall.
