Panel intended primarily for floor structures. To achieve a high degree of impact sound insulation, elastic panels are required under the floor layer, while at the same time the compression of the panel under high loads must be limited. From the acoustic point of view, the panel must be sound-absorbing. These requirements are achieved using a panel which has a core 1 of elastic and sound- absorbing material and a two-part perforated shell 2, 3 around the latter. Under normal loading, the two parts of the shell are disengaged and the elastic properties of the core provide a high degree of insulation. In the event of high loads, the legs of one part of the shell contact the other, and further compression is stopped. <IMAGE> |
