Definitions

  • the invention relates to an acoustic building structure intended to be fixed on the building frame and comprising at least one acoustic assembly which comprises a mineral wool panel and a carrier element of said panel of mineral wool.
  • the acoustic insulation of a building is commonly obtained from mass-spring-mass structures, an example of which is given in the EP 0921242.
  • a structure consists of two masses which are each consisting of a rigid element and which are separated by a panel of mineral wool, such as glass wool, combined with an air knife for constitute the spring.
  • the two rigid elements are arranged on both sides of framework of the building and mechanically attached to the same framework or to metal rails added to the framework. These elements consist of trays in U-shaped section sheet which are lined inside the U of a panel of mineral wool, such as rock wool, to increase the mass effect.
  • the structure described in this document advantageously makes it possible to fix directly the rigid elements on the frame of the building or smooth metal associated with the framework without the need for fixing means intermediate.
  • the structure by nature in sheet metal and the shape in trays of rigid elements, still achieves a cost that would be desirable to decrease.
  • the performance of the acoustic insulation of the building is linked, in addition to the nature of the walls, the thickness and the nature of the spring and the damper, to the surface mass of the structure that is given by the quantity of mineral wool introduced into the supporting element and by the sheet metal nature of the carrier element. Nevertheless, the mass per unit area is sometimes insufficient, it is necessary, in order to increase the acoustic performance, to add a additional load at the bottom of the tray, for example a plasterboard, this which further increases the cost price of the structure.
  • the object of the invention is therefore to provide an acoustic structure, responding in particular to a structure of the mass-spring-mass type, which while keeping the advantages of high-performance sound insulation and simplification in its means of attachment to the frame of the building, be decreased in overall cost.
  • the acoustic structure is characterized in that the carrier element consists of a pair of spaced lower and upper profiles of a step p, which each include, a respective soul facing one of the other, and a respective wing bent perpendicular to the associated soul, the wings being in the same plane and directed towards each other, and the woolen panel mineral being housed between the souls of the profiles, and the acoustic assembly comprises a rigid panel fixed against the outer faces of the flanges of the profiles.
  • This structure has the advantage of directly obtaining mass sufficient surface area to sound insulation without having to add more thicknesses of surface elements as is generally the case for sheet metal trays of the prior art at the bottom of which is associated in addition to plasterboards.
  • the upper profile includes the other side of the soul, parallel and in the opposite direction to the wing a second wing intended for fixing the acoustic assembly against the frame of the building.
  • the lower and upper sections of this mode of embodiment comprise complementary shapes so that the profile upper part of said assembly cooperates with the lower profile of a second acoustic assembly for assembling with said first set acoustic.
  • the lower and are identical and each have a wing parallel to the wing to have a U-shaped section such that the openings of the U are facing each other and between which is stuck the mineral wool panel, fixing the acoustic assembly to the frame of the building being made by means of at least two fasteners between which are intended to be maintained the profiles and of which at least one is intended to be fixed to the frame.
  • the acoustic assembly 1 represented in FIG. 1 according to a first embodiment of embodiment and that shown in FIG. 2 according to a second embodiment are intended to be applied and to be mounted against the vertical walls of a building but could equally well be associated with floors or ceilings for sound insulation.
  • This structure comprises on both sides of the frame 40 of the building, formed by poles metallic or vertical metal rails joined to poles, acoustic assemblies 1 mounted one above the other and constituting, for each face of the structure, each of the masses of said structure, the masses being separated by the spring constituted by a panel of mineral wool 41, such as glass wool, and by an air gap 42.
  • Each acoustic assembly 1 comprises a carrier element 10 a mineral wool panel 20 and a rigid panel 30 contributing to the mass of the assembly and preferably formed by a plasterboard.
  • Acoustic assemblies are generally delivered to the building site pre-assembled way of simply having to perform only the operations of mounting and fastening to the building frame.
  • the dimensions of a set are 400mm in height, from 3.25 to 8 m in length, which is adapted to the distance separating two posts fixing the frame.
  • the width of a set is imposed by the width of the carrier element 10 and the plate of plaster 30, the width of the profiles being adapted to receive panels of mineral wool 70 mm thick, and the plasterboard having a thickness of 12.5 or 15, or 18 mm to achieve a total mass per unit area sufficient acoustics to ensure that the overall sound insulation of the structure is greater than 50 dB (A) according to current standards.
  • the carrier element 10 of an acoustic assembly 1 consists of a pair of lower 11 and upper 12 profiles located in the same plane and spaced a step p, and between which is arranged the mineral wool panel 20.
  • the profiles lower 11 and upper 12 comprise, respectively, a soul 13 and a soul 14 facing each other, as well as a wing 15 and a wing 16 perpendicular to the soul associated and directed towards each other.
  • the invention distinguishes two embodiments of the acoustic assembly 1 depending on the shape of the profiles, generating two separate systems of fastening to the frame of the building.
  • the lower profile 11 has opposite the wing 15, on the other side of the core 13, a wing 15a parallel to the other wing and of the same direction so as to form a U-shaped section to the interior of which can be kept stuck the mineral wool panel 20.
  • the profile 11 is provided with a longitudinal assembly strip 17 intended, as it is will see later, to cooperate with another acoustic set 1.
  • the upper profile 12 of the first embodiment comprises of the other side of the core 14 another wing 16a parallel but opposite direction to the wing 16.
  • This wing 16a is connected to the core 14 by a groove 18, concavity turned towards the direction opposite to the lower profile, and whose bottom is in a parallel plane and located below the plane containing the core 14.
  • the lateral surface 16b which separates the bottom of the throat 18 of the soul 14 participates in the maintenance of the woolen panel mineral 20 inserted between the two sections.
  • the groove 18 of the profile 12 of a first acoustic assembly is intended to accommodate the assembly strip 17 of a lower profile 11 of another acoustic assembly intended to be mounted above of the first set, the core 13 of the lower profile 11 of the second set resting on the core 14 of the upper profile 12 of the first set.
  • the mineral wool panel 20 is inserted, jammed and possibly glued between the two lower profiles 11 and upper 12 against the webs 13 and 14, the wings walls 15, 15a and 16 and the side surface 16b.
  • the rigid panel 30, or the plasterboard is in turn arranged against the outer face of the wings 15 and 16 of the profiles and has a height such that its lower 31 and upper 32 edges are coplanar with the souls 13 and respectively 14 profiles.
  • the fixing of the panel 30 is carried out by any known means, such as by gluing, screwing or nailing.
  • the acoustic assembly 1 is fixed to posts 40 by the upper section 12, near the free end 16c of the wing 16a, by any known fastening means such as self-tapping screws.
  • the wing 16a of the upper profile has a height greater than that of the wing 15a of a lower profile so that the fastening means arranged towards the upper end 16c are high enough not to interfere, during the setting up a second acoustic set on a first set, the application of the wing 15a of the lower section of the second assembly against the wing 16a the upper profile of the first set while the assembly strip 17 is nested in the throat 18.
  • the rigid panel 30 constituted by a plasterboard is fixed against the external faces of the wings 15 and 16 of the lower and respectively upper profiles, its height being adapted so that its lower edges 31 and upper 32 are coplanar with the cores 13 and 14 of the profiles.
  • lower fasteners 50 are provided (FIG. 4) and intermediate 60 (FIG. 5).
  • intermediate part 60 can be replaced by a piece identical to that of the lower attachment 50.
  • the lower part 50 is only used for the fixation of the first acoustic unit to be arranged near the floor, the room lower 50 cooperating with the lower profile 11.
  • the intermediate part 60 plays the role of fastening means of acoustic assemblies mounted above the first set, the intermediate piece 60 cooperating on the one hand with the profile 12 of the first set, and on the other hand with the lower and superior of the other sets arranged above.
  • the lower fastener 50 has a core 51 and on each side of this soul and perpendicular thereto, a fixing wing 52 and a wing 53, both facing each other.
  • the width of the soul 51 is substantially greater than the width of an acoustic assembly.
  • the part 50 is intended to be mounted in first place to receive the first acoustic set.
  • the fixing wing 52 is intended to be mounted by its outer face against the frame of the building, the inner faces of the fastening flange 52, the core 51 and the holding flange 53 being intended to support, respectively, the wing 15, the core 13 of the profile 11 and the outer face of the plasterboard 30.
  • the fastening flange 52 is high enough that its means of attachment to the frame do not interfere the application of the wing 15 of the profile against it.
  • the intermediate fastener 60 has an I-shaped section. It comprises a fixing surface 61 and a retaining surface 62 parallel to the attachment surface and connected thereto by a connecting surface 63 whose width is substantially greater than that of an acoustic assembly.
  • the surface link 63 delimits an upper housing channel 60a and a lower channel of housing 60b.
  • the fixing surface 61 is intended to be mounted against the building frame while the connecting surface 63 is intended to receive in support the core 14 of the upper profile of the first set acoustic and the core 13 of the lower profile of a second acoustic assembly intended to be placed above the first set, and the retaining surface 62 is intended to ensure that the two sets are held in position by the support against this one gypsum board 30 of said sets.
  • the attachment is made by means of identical pieces 50 in the form of a square.
  • the mounting of a part on the upper section of an acoustic assembly is realized by fixing by screw for example the fixing flange 52 to the frame of the building and the core 51 to the core 14 of the profile.
  • Figure 6 illustrates two acoustic sets according to the first mode of realization once mounted and fixed.
  • the first acoustic assembly 1 is positioned to rest on a wooden sole 1a fixed to the ground and is kept pressed against the frame by nailing a wooden batten 1b to the sole 1a.
  • the first set is then set at posts of the frame 40 by joining the wing 16a of the upper profile to the level of its upper end 16c by means of screws 41.
  • a second acoustic assembly 1 is then mounted above the first set.
  • the assembly strip 17 of the profile is first engaged lower 11 in the groove 18 of the upper profile 12 of the first set already fixed, and then rocking said assembly to the frame of the building so as to fit the strip in the groove, to seat the core 13 of the lower profile on the core 14 of the upper profile of the first set, and to press the assembly against poles.
  • this second assembly is fixed by screwing the wing 16a of the profile higher than the poles.
