  • walls with integrated acoustic formwork are known which are used for the construction of buildings (in particular in the urban or peri-urban environment) or noise barriers. These walls with integrated acoustic formwork are designed in such a way that noise pollution external to a building is attenuated inside this building. These walls with integrated acoustic formwork are then configured to provide acoustic correction, more particularly by adding a sound-absorbing or correcting material.
  • Such a wall with integrated acoustic formwork comprises at least, on the one hand, a first skin oriented in the direction of the exterior of a building and usually made of concrete, on the other hand, a second skin oriented in the direction of the interior of the building and usually made of concrete, on the other hand again, means for connecting these two skins and, on the other hand also, acoustic insulation means which usually take the form of at least one panel , which is made of an acoustic insulating material, and which is fixed, as the case may be, on the first skin and/or on the second skin, more particularly on an outer face of such a skin oriented in the direction of the outside of the wall with integrated acoustic formwork.

  • the acoustic insulation means can be fixed (in particular by gluing or by means of mechanical fixing means) on the first skin and/or on the second skin of such a wall with integrated acoustic formwork, this on an outer face of such a skin oriented towards the outside of the wall and during a method of manufacturing such a wall with integrated acoustic formwork in the factory.
  • Such a way of proceeding requires, before fixing such acoustic insulation means on such a skin, to wait until the concrete of this skin is sufficiently dry, which lengthens the duration of such a manufacturing process.
  • a second embodiment consists in fixing such insulation means acoustic on such a skin (more particularly on the external face, oriented towards the outside of the wall, of a second skin oriented towards the interior of a building) not in the factory but on site, this after having installed the wall with integrated formwork.
