The present invention relates to a flooring structure in which the beams (1, 8) of the flooring structure are not interconnected with one another apart from in certain discrete points, for example in bearing supports. In this instance, the bearing beams (1, 8) of the flooring structure do not dynamically co-operate with one another in any significant manner. As a result, improved footstep sound insulation will be obtained since the flooring structure only reacts locally to a dynamic loading. The flooring structure emits only sound in an area close to the applied dynamic loading. In the flooring structure according to the present invention, the beams (1, 8) lie considerably closer to one another compared with that which has previously been normal for light wooden flooring structures. In one embodiment of the present invention, the beams (8) and/or studs (10) placed between the beams (1, 8) and floor panels (5) are provided with grooves (9). As a result of these grooves (9) torsional and compression rigidity at the anchorage points with the floor are reduced, which gives improved footstep sound insulation compared with beams and/or studs without grooves.
L'invention concerne une structure parquet dans laquelle les poutres (1, 8) ne sont pas reliées les unes aux autres sauf au niveau de certains points discrets, par exemple au niveau des surfaces portantes. Dans ce cas, les poutres porteuses (1, 8) de la structure ne coopèrent pas dynamiquement les unes avec les autres d'une manière significative. Par conséquent, on obtient une isolation phonique (bruits de pas) améliorée puisque la structure ne réagit que localement à une charge dynamique et n'émet un son que dans la zone proche de la charge dynamique appliquée. Les poutres (1, 8) sont beaucoup plus proches les unes des autres que dans les structures planchers en bois légères existantes. Dans l'un des modes de réalisation, les poutres (8) et/ou les solives (10) placées entre les poutres (1, 8) et les panneaux de plancher (5) présentent des rainures (9). Ces dernières diminuent la rigidité en torsion et en compression au niveau des points d'ancrage dans le sol, ce qui améliore l'isolation phonique (bruits de pas) par rapport aux poutres et/ou solives non rainurées.
