Definitions

  • the object of the invention is to provide an acoustic building structure that meets the mass-spring-mass insulation principle and comprising wool panels mineral.
  • the invention will be described more particularly for an acoustic partition of building, but it is not limited to this particular type of acoustic structure of building, vertical linings, floors and ceilings intended for sound insulation in various buildings is also part of the invention.
  • mass-spring-mass systems meet the criteria sound insulation or correction, systems are, for example, partitions made of mineral wool panels positioned between at least two plasterboards or vertical linings made of mineral wool panels associated with at least one plasterboard and glued or mechanically attached to a masonry or concrete wall. Variants of these systems are extremely numerous, their performance depending on three parameters: surface mass and nature of the walls, thickness and nature of the spring and thickness and nature of the shock absorber.
  • the object of the invention is to provide an acoustic building structure that meets the mass-spring-mass insulation principle which allows very good insulation efficient and quick and easy to install in order to reduce the overall cost of system.
  • an acoustic building structure that meets the mass-spring-mass isolation principle, the two masses of the mass-spring-mass system each comprising at least one rigid element and being separated by at least one mineral wool panel associated with at least one air space.
  • Said structure is such that the rigid elements are U-shaped plates and are filled inside the U with at least one mineral wool.
  • two masses of the system are mechanically fixed to elements of the building, advantageously the two masses of the system are arranged on the side and other elements of the structure of the building.
  • the trays thus filled constitute the masses of the system whose surface mass is controlled thanks to the filling and this filling adds to the mass effect, the intrinsic qualities of wool mineral for their acoustic behavior. This association of a plateau and mineral wool thus constitutes an effective acoustic facing.
  • such rigid elements attached to building elements such as elements of the building frame also serve as a supporting frame.
  • building elements such as elements of the building frame
  • partitions made of mineral wool panels positioned between at least two plasterboards these plates constituting the system masses, it is not necessary to use a metal frame in supplement to the framework of the building to fix the said masses of the system.
  • the use of such rigid elements makes it possible to eliminate this metal frame and thus the installation of the system masses is simplified and more fast.
  • the sound reduction index of the structure is greater than 50 dB (A) and preferably greater than 60 dB (A).
  • the ends of the wings of the U of the tray have complementary shapes allowing to fit the trays inside each other so that the bottoms of the trays form a continuous surface. In this way, it is possible to realize large surface by minimizing the points of attachment of the trays to the elements of the building; the trays fitting into each other, they can be fixed mechanically on only one of their ends.
  • one of said ends is a simple folding towards the outside of the tray and the other end is profiled so to receive the folded end of another tray and to present a wing which extends towards the outside of the tray parallel to the bottom of the tray.
  • the profiled end allows, thanks to the wing, to secure the plate easily because access to this wing remains clear once the tray is in place.
  • this profiled end allows positioning and maintenance of the padding of the tray without risk of damage.
  • the end receiving part folded from another tray, positioning and holding it at this level part of the plate and in the opposite part of the plate, the lining is maintained by the wing of the profiled end of the neighboring plateau.
  • At least one of the plates is made of sheet metal full.
  • At least one of the plates is in perforated sheet, these perforations of the tray allowing to benefit from the role sink of the mineral wools lining the tray.
  • the structure is not only efficient in terms of sound insulation, but also more, it is efficient in terms of acoustic correction, this one presenting a good absorption coefficient.
  • the plates are fixed to the building elements via a simple or acoustic spacer.
  • the acoustic spacers also make it possible, on the plan acoustic, independent masses avoiding the transmission of vibrations.
  • the simple or acoustic spacer has a adjustable spacer length. In this way you can adjust the thickness of the air gap as needed from a single type of spacer.
  • the plates are lined with the inside of the U of a mineral wool of high density such that, for example, rock wool.
  • Rock wool having a density generally higher than the density of glass wool, allows to increase the general surface mass of the plate in comparison with the use of glass wool.
  • the trays are lined inside U of a low density mineral wool such as glass wool and at least one additional load, such as a plasterboard, positioned at the bottom of the tray or on the surface.
  • a low density mineral wool such as glass wool
  • at least one additional load such as a plasterboard
  • the bottom of the two plates is facing the outside of the structure.
  • the mineral wool lining the inside of the trays combine three basic acoustic functions. It increases the mass, it acts as a complementary damper and it increases the thickness of the air gap. This type of achievement is particularly effective for sound insulation.
  • the bottom of the two plates is facing the inside of the structure.
  • mineral wool combines two acoustic functions fundamental. It increases the mass and it plays a role of dissipator. This type of embodiment is advantageous for acoustic correction.
  • the bottom of one of the trays is turned towards the outside of the structure and the bottom of the second tray is facing the inside of the structure.
  • the plates constitute the support of the facings necessary to finish the acoustic structure such as, for example, drywall or siding.
  • Such facings may have a purely aesthetic function, but must not harm the acoustic behavior of mineral wools. Indeed, when they play a role of dissipator, the covering will be done, for example, by a perforated sheet or by absorbent material.
  • the use of various facings will be generally based on criteria for sound insulation, correction acoustics, aesthetics, fire resistance, cost ...
  • Figure 1 a horizontal section of an acoustic structure according to the invention.
  • Figure 2 a horizontal section of another acoustic structure according to the invention.
  • Figure 3 a vertical section of a first type of embodiment of a acoustic structure according to the invention.
  • Figure 4 a vertical section of a second type of embodiment of a acoustic structure according to the invention.
  • Figure 5 a vertical section of a third type of embodiment of a acoustic structure according to the invention.
  • the different acoustic structures represented consist of trays 1 and 2 lined with rock wool panels 3 and separated by glass wool panels 4 associated with an air space 5.
  • the trays 1 and 2 are sheet metal trays full galvanized with a U-shaped section and a sheet thickness of 0.75 mm.
  • the dimensions of the trays 1 and 2 are 70 mm deep, 400 mm height and 3.25 to 8 m in length, this length will be adapted to the distance between the two elements of the building framework on which panels 1 and 2 will be fixed. These elements of the structure of the building are represented in Figures 1 and 2 in the form of posts 6 and 7 in metal structure.
  • the plates 1 or 2 are assembled together by fitting their sides 8 and 9. In this way, we easily obtain the height or width of the acoustic structure by positioning of the plates 1 or 2 nested between them.
  • the side 9 has a tongue 17 which is inserted in the profiled zone 18 on the side 8 of a neighboring tray 1 or 2, the two trays 1 or 2 thus fitted have their bottoms 10 or 11 located in the same plane.
  • the wing 19 on the side 8 allows the fixing of the plates 1 or 2 to building elements by any means known to those skilled in the art such as, for example, through a distance.
  • Such a type of tray 1 or 2 is advantageous for the installation of rock wool panels 3: between the profiled area 18 and the bottom 10 or 11 of the tray 1 or 2, insert the edge of the rock wool panel 3 then position the rest of panel 3 on the bottom 10 or 11 of the tray 1 or 2.
  • the rock wool panels 3 are inserted, these panels 3 having a thickness of 70 mm and a density of approximately 110 kg / m 3 .
  • the glass wool panels 4 are positioned between the two posts 6 and 7 by any means known to those skilled in the art such as, for example, by means of a racking-in device.
  • Panels 4 of glass wool have a thickness of 120 to 200 mm and have on one side a single or aluminum vapor barrier.
  • Such panels 4 are, for example, type of those manufactured by ISOVER SAINT-GOBAIN and marketed under the name MONOSPACE 36.
  • the acoustic structures thus assembled respond to the mass-spring-mass isolation principle: the masses being constituted by the set of trays 1 and 2 lined with panels 3 of rock wool.
  • the realization of such structures, due to the presence of the plates 1 and 2 fixed to the posts 6 and 7, is thus quick to implement and simplified compared to existing acoustic structures.
  • FIG. 1 represents an acoustic structure whose bottoms 10 and 11 of the trays 1 and 2 are turned towards the outside of the structure.
  • These trays 1 and 2 are fixed to the posts 6 and 7 of the building by means of spacers 12 such acoustic spacers are known to those skilled in the art profession such as, for example, the antivibrators marketed by the company PAULSTRA.
  • These acoustic spacers 12 allow the masses of the acoustically independent mass-spring-mass system avoiding the transmission of vibrations.
  • the back of trays 1 and 2 each receive plasterboard 13 and 14 as finishing siding. These plasterboards 13 and 14 are fixed directly to the plates 1 and 2, for example, by screwing, the latter then also serving as a facing support.
  • Such a structure acoustics is particularly suitable, as we will see later, as that building insulating partition.
  • FIG. 2 represents an acoustic structure whose bottoms 10 and 11 of the trays 1 and 2 are turned towards the inside of the structure.
  • These trays 1 and 2 are fixed directly to the posts 6 and 7 of the building by any means known to those skilled in the art such as, for example, by screwing or nailing.
  • Orientation panels 1 and 2 is such that the rock wool panels 3 constitute the external faces of the acoustic structure. Therefore, a perforated sheet 15 is fixed by any means known to those skilled in the art to the visible edges of the trays 1 and an external steel tank 16 is fixed by any known means of a person skilled in the art with visible edges of the plates 2.
  • the perforated sheet 15 and the external steel tank 16 are, for example, fixed by simple screwing.
  • Such an acoustic structure is particularly suitable, as we will see later, as an absorbent acoustic partition of building.
  • FIG. 3 represents a vertical section of a first type of embodiment of an acoustic structure according to the invention.
  • Figure 4 shows a vertical section of a second type of embodiment of an acoustic structure according to the invention.
  • Figure 5 shows a vertical section of a third type of production of an acoustic structure according to the invention.
  • the bottom 10 of the plate 1 is turned towards the inside of the structure and the bottom 11 of the plate 2 is turned towards the outside of the structure.
  • the rock wool lining the trays 1 and 2 combine the different acoustic functions described in the two first previous types of realization and this according to the orientation of plates 1 and 2.
  • This particularly advantageous embodiment makes it possible to obtain very effective acoustic insulation while keeping a correction high-performance acoustics on one side of the structure. This achievement is particularly suitable for the implementation of building envelopes.
  • the invention is not limited to the types of embodiment shown on the different figures.
  • the plates 1 and 2 can advantageously be made of sheet metal galvanized perforated to benefit from the dissipative role of rock wool lining the trays 1 and 2, in particular when the bottoms 10 and 11 of the plates 1 and 2 are turned towards the outside of the structure, these plates being able to receive facings such as plasterboard.
  • the trays 1 and 2 can also be lined with glass wool panels, the surface mass of the trays 1 and 2 then being increased by adding a load to the bottom of the plate or on the surface additional.
  • a filler can be, for example, a plasterboard connected to the bottom of the plate by means of a mineral binder of the type, by example, adhesive plaster.
  • the invention must be interpreted in a nonlimiting manner and encompassing all type of acoustic building structure that meets the principle of mass-spring-mass insulation, the two masses of the mass-spring-mass system comprising each at least one rigid element and being separated by at least one panel mineral wool associated with at least one air space, the rigid elements being trays with a U-shaped cross-section and being filled inside the U with at least one mineral wool.
