Definitions

  • the present invention relates to self-supporting partitions used, in particular, for industrial workshops and the like, including a body of concrete, cement or similar material.
  • the object of the present invention is to provide a partition of the type indicated above which, as well as having the usual properties of structural strength, can also reduce the noise which builds up in the internal environment.
  • a self-supporting partition including a body of concrete, cement or similar material, characterised in that at least one container is associated with the body and has at least one cavity which communicates with the exterior through at least one duct and is at least partially filled with material having sound-absorbent properties.
  • the container thus acts as a Helmholtz resonator, absorbing sound vibrations within a certain range of wavelengths which can be calculated, by formulae known to an expert in the art, from the dimensions of the cavity and of the duct which connects it to the exterior and from the properties of the sound-absorbent material.
  • a self-supporting partition particularly for industrial workshops and the like, includes a body 2 of cement, concrete or similar material, in which a container 4 having sound-absorbent properties is set.
  • the container 4 is formed by a flat base partition 6 which acts as a protective covering and to which an upper partition having characteristics of structural strength adheres.
  • the upper partition is shaped so as to have a plurality of frusto-pyramidal projections 8, each of which defines a cavity 10.
  • Each projection 8 has a hole 12 in which a sleeve 14 is fitted, the sleeve 14 having a first portion 14a which projects into a duct 17 in the body 2 for communication with the exterior, and a second portion 14b which is inserted through the partition of the projection 8.
  • First and second layers 16, 18 of sound-absorbent material are disposed in the bottom and in the central portion of the cavity 10 of each projection 8, respectively.
  • the not occupied space by the sound-absorbent layers 16, 18 in the cavity 10 is filled with material suitable for providing the container 4 with adequate properties of mechanical strength.
  • each cavity 10 communicates with the outside environment and can act as a Helmholtz resonator to cancel out sound vibrations within a predetermined range of wavelengths.
