Description

Technical Field

[0001] The invention relates to a wall element according to the preamble of claim 1, and to a profile element according to claim 14. In addition, the invention relates to a method for manufacturing a wall element according to claim 15.Background

[0002] In the prior art it is known to divide a space in a building into multiple spaces by placing a partition wall. Such a partition wall comprises one or more wall panels that are connected to each other. Here a wall panel consists of a frame of studs and beams made of metal, usually steel, wherein on the frame on both sides a cover plate such as a gypsum board or a wood-based board is provided. The studs and beams consist of profile elements that are connected to each other to form the frame. The studs are substantially vertical elements that after placement of the partition wall extend between floor and ceiling of the space. The beams are substantially horizontal elements that after placement extend along floor or ceiling.

[0003] A known disadvantage of a wall panel according to the prior art is that sound damping leaves something to be desired. Between two spaces that are separated from each other by a partition wall of wall panels, sound is often transmitted at a level perceptible to a user of the space(s).

[0004] It is known in the prior art that for this reason an insulation material is provided between the cover plates in wall panels. However, in many applications the achieved sound damping is still insufficient. Based on the standards that depend on the wall type, the applicability is adversely limited.

[0005] It is an objective of the invention to eliminate or counteract the mentioned disadvantages.Summary of the invention

[0006] The objective is achieved by a wall panel comprising at least two studs, two beams, wherein the studs and beams are connected to each other in a frame, with the studs parallel to each other in a first direction and the beams parallel to each other in a second direction perpendicular to the first direction; wherein the studs and the beams are formed from a stud profile and beam profile respectively, wherein the opening between the flanges of the respective profile is in each case turned toward the interior of the frame, wherein in the wall panel at least one acoustic resonator of the Helmholtz type is provided, wherein the acoustic resonator comprises a body with a cavity and is provided with an opening in the cavity to an environment of the acoustic resonator.

[0007] The at least one acoustic resonator of the Helmholtz type provided in the wall panel comprises a body with a cavity that is in communication via at least one opening with the atmosphere in the environment of, that is to say outside, the acoustic resonator. The combination of the size of the cavity and of the at least one opening is substantially determinative of a resonance frequency (range) of the acoustic resonator. Vibration of the air mass in the opening of the resonator, caused by external pressure fluctuation caused by sound, leads to resonance of the air mass in the cavity of the resonator. Depending on the configured frequency range of the resonator, a setting can be obtained that leads to damping of sound in a desired frequency region.

[0008] In an embodiment, the acoustic resonator is configured to dampen at one or more frequencies in the region of approximately 100 - approximately 5000 Hz.

[0009] For many applications, sound in this frequency range is disturbing to observers. Damping in this frequency range leads to less sound transmission between spaces on both sides of a partition wall provided with wall panels according to the invention.

[0010] In practice, a sound reduction value is often used that is determined by measurement over a broad frequency range, expressed in an RW number (Sound Reduction Index, in dB). For standardization, a range from 100Hz to 5000Hz is used. However, the invention can also realize sound reduction for sound above 5000 Hz.

[0011] In an embodiment, the invention provides a wall panel as described above, wherein the acoustic resonator has the shape of a volume that is accommodated in the respective profile of the stud or beam. In an advantageous manner it is achieved that the resonator is placed at a predetermined location within the frame of the wall panel, whereby the configuration of the acoustic resonator can be optimally adjusted. In addition, this makes it possible to fit the length of the acoustic resonator within the available length of the beam or stud. Thus an acoustic resonator placed in the profile of the beam can have a length that extends to at most substantially the distance between the studs of the wall panel, or when the acoustic resonator is placed in the profile of a stud the length can extend to substantially the distance between the beam on the floor and the beam on the ceiling. This creates freedom for the designer to adjust the length and thus the size of the resonator body within wide limits. The shape of the acoustic resonator body can be freely chosen provided the acoustic resonator can be placed in the profile of stud or beam.

[0012] In a preferred embodiment, the acoustic resonator body has a rectangular shape that is accommodated within a width of the profile of a stud or a beam. In this way the construction of the wall panel is simplified because the acoustic resonator can be integrated in stud or beam prior to the construction of the wall panel.

[0013] In an embodiment, the invention provides a wall panel as described above, wherein the at least one opening is provided in a top surface of the resonator body, which top surface extends between the flanges of the respective profile and is facing away from the web thereof.

[0014] In an embodiment, the invention provides a wall panel as described above, wherein one or more walls of the body of the acoustic resonator are provided with a relief or processed by embossing. The pattern applied by the processing strengthens the walls of the acoustic resonator against deformation and loss of damping is counteracted.

[0015] In an embodiment, the invention provides a wall panel as described above, wherein the cavity of the body of the acoustic resonator on a bottom surface opposite the top surface is provided with a layer of sound-absorbing material to improve the damping. The cavity in the resonator body is thus bounded by the top surface and by the top layer of the sound-absorbing layer. In a further embodiment, the sound-absorbing material is selected from a compressed mineral wool or a melamine foam.

[0016] In an alternative or additional embodiment, sound-absorbing material can also be applied on an exterior surface of the body of the acoustic resonator.

[0017] In an embodiment, the invention provides a wall element wherein the acoustic resonator comprises a double-walled panel that is placed within the frame and is provided with two parallel walls that are held at a distance from each other by spacers so that the cavity exists as at least a portion of an intermediate space between the parallel walls, wherein in one of the parallel walls one or more holes or slot openings are provided so that one or more acoustic channels are formed between the at least one portion of the intermediate space and a space outside the double-walled panel.

[0018] Furthermore, the invention relates to a profile element for forming a wall panel element formed from a stud profile, respectively a beam profile, wherein in the respective profile of the profile element an acoustic resonator of the Helmholtz type is provided, and wherein the acoustic resonator comprises a body with a cavity and is provided with an opening between the cavity and an exterior environment of the acoustic resonator.

[0019] Furthermore, the invention relates to a method for manufacturing a wall element comprising at least a pair of studs, a pair of beams, wherein the method comprises: providing studs and beams that are formed from a stud profile, respectively a beam profile; connecting the studs and beams to each other in a frame, with the studs parallel to each other in a first direction and the beams parallel to each other in a second direction substantially perpendicular to the first direction, wherein the opening between the flanges of the respective profile is in each case turned toward the interior of the frame, further comprising providing an acoustic resonator within the frame of at least one of the studs and the beams, wherein the acoustic resonator is of the Helmholtz type, wherein the acoustic resonator comprises a body with a cavity and is provided with at least one opening between the cavity and an exterior environment of the acoustic resonator.

[0023] The figures are schematic in nature and details in the figures are not necessarily shown to scale.Description of exemplary embodiments

[0024] Further features, application possibilities and advantages of the invention appear from the following description of exemplary embodiments of the invention, which are shown in the figures. In this context, all described or shown features in themselves or in any combination form the subject of the invention, independently of their summary in the claims or of their formulation or representation in the description or the figures.

[0025] In the following description, the same reference numerals are used in the figures to indicate in each case identical or corresponding components.

[0026] Figure 1 shows schematically a frame of a wall panel 100 in side view according to an embodiment of the invention.

[0027] The wall panel 100 is shown in an arrangement between a floor 120 and a ceiling 125. The wall panel 100 is constructed from at least two types of profile elements: stud elements or studs 2 provided with a stud profile and beam elements or beams 4 provided with a beam profile.

[0028] The wall panel 100 comprises at least two studs 2 and at least two beams 4. The beams 4 extend in a first direction along the floor and parallel thereto along the ceiling. The studs 2 extend in a second direction between the floor 120 and the ceiling 125. The studs 2 and beams 4 are connected to each other in a frame 3, wherein the ends of the profile of a stud 2 are in each case accommodated in the profile of one of the beams 4.

[0029] On the formed frame 3, a plate (not shown) is provided on both sides so that a wall is formed between floor and ceiling. In many cases the space in the frame 3 between the plates is filled with a wool material (not shown) for improving sound insulation.

[0030] In an embodiment, the wool material is a mineral wool.

[0031] In an embodiment of the wall panel 100 as described, an acoustic resonator of the Helmholtz type 10; 20 is accommodated in the frame 3. The acoustic resonator 10; 20 comprises a body within which a cavity is formed that is in communication via at least one opening with the atmosphere outside the cavity as will be explained in more detail below in Figures 5 and 6. Resonance of the air mass in the cavity of the resonator can, depending on the configured frequency range of the resonator, lead to damping of external sound in the desired frequency region.

[0032] Details of an embodiment are discussed with reference to the following figure 2.

[0033] Figure 2 shows schematically a portion of a frame 3 of a wall panel 100 in perspective view according to an embodiment of the invention.

[0034] In the embodiment, the invention provides that the acoustic resonator 10; 20 is accommodated in one of the studs 2 or beams 4.

[0035] This has the advantage that the acoustic resonator 10; 20 can be integrated with the stud 2 or beam 4 prior to the construction of the wall panel 100. Optionally as shown here in figure 2, multiple acoustic resonators can be placed in the wall panel, for example in one of studs 2 and one of the beams 4.

[0036] The length of the resonator can be chosen depending on the available length within the stud 2 or beam 4 in which the resonator is installed. The length of the resonator in a beam 4 can thus be at most the free length (i.e. the distance) between the two studs 2 of the wall panel 100. In a stud 2 the length of the resonator can be at most the free length (the distance) between the beam 4 on the floor 120 and the beam 4 on the ceiling 125.

[0037] In an example without limiting the invention thereto, the distance between adjacent studs 2 is substantially 60 centimeters, between floor and ceiling beams 4 the distance is in many cases approximately 3 meters, depending on the shape of the space in the building.

[0038] The acoustic resonator 10; 20 can have any shape provided the resonator can be accommodated in the profile of the stud 2 or the beam 4.

[0039] As shown in figure 2, in a preferred embodiment the body of the acoustic resonator 10; 20 has a rectangular shape that connects to the profile of the stud 2 or beam 4 in which the resonator is placed.

[0040] Figure 3 shows schematically a cross-section of a beam profile 40.

[0041] A beam profile 40 has in an embodiment a U-profile. The profile consists of a middle portion 4-1 and two side walls 4-2, 4-3 positioned at an angle that are connected to the middle portion. The middle portion 4-1 has a predetermined width 41, the side walls have a predetermined height relative to the middle portion. The middle portion is referred to as web, the side walls as flanges. The web 4-1 is connected during the construction of the wall panel 100 to floor 120 or ceiling 125. The flanges are connected to the plates when these are provided. Also a stud profile is connected to the flanges to form the frame 3.

[0042] Figure 4 shows schematically a cross-section of a stud profile 21.

[0043] A stud profile 21 has in an embodiment a C-profile. The profile consists of a middle portion 2-1 and two side walls 2-2, 2-3 positioned at an angle that are connected to the middle portion. The ends 2-4;2-5 of the side walls 2-2;2-3 are bent inward. The middle portion 2-1 of the stud 2 has a predetermined width 21, the side walls of the stud 2 have a predetermined height relative to the middle portion.

[0044] For application in a wall panel 100 according to an embodiment, the width 22 of the stud profile 21 is smaller than the width 41 of the beam profile 40 so that a stud 2 can be placed within a beam 4.

[0045] The external width of a stud profile corresponds to the internal width of a beam profile so that the stud profile can be placed fittingly in the beam profile.

[0046] In an example without limiting the invention thereto, a U-profile 40 has a width of 75mm with a flange height of 40mm, and a matching C-profile 21 has a width of 73.8mm with a flange height of 49mm on one side and 51mm on the opposite side of the profile. It is clear to the person skilled in the art that other profile dimensions are available and applicable.

[0047] Figure 5 shows schematically a cross-section in perspective view of an acoustic resonator 10; 20 according to an embodiment of the invention.

[0048] In an embodiment, the body of the acoustic resonator 10; 20 has a rectangular shape within which the cavity 13 extends. Preferably the body has an external width 16 that corresponds to the internal width of the profile 21; 40 within which the body is placed fittingly. The profile of the stud 2 or beam 4 is shown in the figure with dotted lines. On a top surface 11 of the body that is turned away from the web of the profile in which it is placed, the body comprises at least one opening 15 that forms a connection between the atmosphere and the interior of the cavity 13 in the body.

[0049] In an embodiment, the opening 15 is located between an imaginary centerline (shown dashed in the figure) of the top surface 11 in the longitudinal direction of the acoustic resonator and one of the flanges of the respective profile 21;40 in which the acoustic resonator 10;20 is placed.

[0050] In an example without limiting the invention thereto, the body has a width of slightly less than 73.8mm and a height of approximately 50mm, the profile an internal width of 73.8mm, and the opening 15 has a diameter between 3 and 10 mm. Within the rectangular body the cavity 13 is present in which acoustic resonance can occur.

[0051] Optionally, multiple openings to the cavity can be made in the top surface 11 of the acoustic resonator.

[0052] In an embodiment, each opening is in each case placed between the centerline and one of the flanges of the profile 21;40.

[0053] The rectangular body of the acoustic resonator can be formed from flat metal plate or steel plate.

[0054] In a further embodiment, the rectangular body of the acoustic resonator is manufactured from metal plate or steel plate provided with a relief or a pattern obtained by embossing / sheet metal working. The relief or pattern contributes to a reinforcement of the plate material, whereby elastic deformation of the plate is reduced and thereby caused damping of the resonance in the cavity 13 is reduced.

[0055] Figure 6 schematically a cross-section in perspective view of the body of an acoustic resonator 10;20 according to a further embodiment of the invention.

[0056] In a further embodiment, the body of the acoustic resonator in the cavity 13 is provided with a sound-absorbing layer 14 on a bottom surface 12 opposite the top surface 11 of the body of the acoustic resonator in order to improve the resonance properties of the cavity or to adjust the resonance frequency(ies) to a desired frequency range.

[0057] On the bottom surface, a layer 14 of an insulation material is applied. The insulation material can be a foam, preferably a melamine foam, or a wool material, preferably a mineral wool.

[0058] The sound-absorbing layer 14 has a thickness that is smaller than the interior height 17 of the cavity 13, preferably not more than approximately 25% of the interior height.

[0059] In an alternative or additional embodiment, the sound-absorbing material can also be applied as a layer on an outer side of the body of the acoustic resonator.

[0060] Details of an embodiment are discussed with reference to the following figures 7 - 9A, 9B.

[0061] In this embodiment, the wall element comprises an acoustic resonator that consists of a double-walled plate with an intermediate space wherein at least one of the walls of the plate is partly provided with openings to the intermediate space. This is further explained with reference to figures 8A, 8B and 9A, 9B.

[0062] Figure 7 shows an exploded view of a wall panel according to an embodiment of the invention.

[0063] In this embodiment, the wall panel 200 comprises studs and beams that, in a similar manner as described with reference to the preceding embodiments, form a frame for the panel, cover plates 205 that are applied on both sides to the formed frame, and an acoustic resonator (acoustic element). The acoustic resonator is applied within the formed frame and between the cover plates.

[0064] By the use of the cover plates on both sides of the frame, a wall panel is obtained for forming a partition wall that can be placed in a space and that thus divides said space into two relatively smaller spaces separated from each other by the wall panel.

[0065] The acoustic resonator is now described in more detail with reference to figures 8A, 8B and 9A, 9B.

[0066] Figures 8A and 8B show a front view and rear view respectively of the acoustic resonator placed within the studs and beams according to the embodiment of Figure 7.

[0067] The acoustic resonator is a rectangular panel that is designed in terms of dimensions to be placed within the beam U-profiles, and between the cover plates when the wall panel is completely finished.

[0068] Optionally, the dimension of the rectangular panel in length is smaller than the height of the wall panel such that a wall panel with the rectangular panel therein comprises a recess above or below the rectangular panel for, for example, cabling and / or pipework.

[0069] The acoustic resonator is a Helmholtz resonator that is configured for damping sound within a predetermined frequency range as already explained above. To this end, the acoustic resonator consists of a double-walled panel, wherein between the walls of the double-walled panel an intermediate space that forms a cavity is configured. On one side of the double-walled panel, a pattern of a number of holes or slot openings is provided in the wall thereof so that one or more acoustic channels are formed between the intermediate space and the outside of the double-walled panel. The opposite side of the double-walled panel consists of a closed wall without holes or slot openings.

[0070] The pattern of the holes or slot openings, the size of the holes or slot openings and the distance between the walls of the double-walled panel 210, 220 determine the acoustic response (frequency range and associated damping) of the acoustic resonator.

[0071] The dimensions of the double-walled panel are limited by the dimensions of the interior volume of the wall panel, wherein some space is left between the double-walled panel, and the studs, beams and cover plates for flow of air.

[0072] In an example without limiting the invention thereto, a hole in the double-walled panel can have a diameter between approximately 3 mm and approximately 20 mm. A center-to-center distance of the holes can be, for example, between approximately 30 mm and approximately 400 mm. The distance between the walls 210, 220 can be, for example, between approximately 20 mm and approximately 60 mm.

[0073] When the wall panel is used as a partition wall, in such a case an acoustic damping on both sides of the wall panel can be necessary. In an embodiment, the acoustic resonator comprises a first resonator portion 210 in which the holes or slot openings are directed toward a first side of the wall panel and a second resonator portion 220 in which the holes or slot openings are directed toward a second side of the wall panel 200 located opposite the first side.

[0074] In an embodiment, the double-walled panel comprises in the longitudinal direction the first resonator portion next to the second resonator portion wherein the intermediate space is divided by means of a crossbar 215 in the width direction of the double-walled panel into a first intermediate space belonging to the first resonator portion and a second intermediate space belonging to the second resonator portion. Figure 8A shows the first side of the double-walled panel having in the upper portion a wall of the first portion provided with holes or slot openings. In the lower portion of the double-walled panel, on the same first side, there is a wall of the second portion, closed, without holes or slot openings. Figure 8B shows the opposite second side of the double-walled panel that is provided in the upper portion having the closed wall of the first portion and in the lower portion having the wall with holes or slot openings of the second portion.

[0075] Figure 9A, 9B shows a cross-section of the acoustic resonator according to the embodiment of figures 7, 8A and 8B along lines IXA-IXA, resp. IXB-IXB.

[0076] The acoustic resonator comprises a double-walled panel with two parallel walls 230, 232 that are held at a distance from each other by spacers 216 so that there is an intermediate space 225 between the parallel walls. In one 230 of the parallel walls, holes or slot openings 235 are provided so that an acoustic channel is formed between the intermediate space 225 and a space outside the double-walled panel. The spacers 216 can have the form of crossbars or cross slats that are connected to the parallel walls 230, 232.

[0077] In an alternative embodiment, the double-walled panel is provided in its longitudinal direction with an intermediate slat that divides the panel into two resonator portions that are parallel to each other in the longitudinal direction, wherein one resonator portion is provided with holes or slot openings directed toward one wall of the double-walled panel and the other resonator portion is provided with holes or slot openings directed toward the opposite wall of the double-walled panel.

[0078] In an alternative embodiment, the double-walled panel can be divided into multiple, i.e. more than two, acoustic resonator portions that either have openings in one of the parallel walls 230, 232 or in the other of the parallel walls. For example, the division of the acoustic resonator portions can be a block pattern (not shown) or a pattern of parallel strips (not shown).

[0079] In a further embodiment, in the intermediate space of the double-walled panel there is a thin layer of sound-absorbing material (not shown) on that one wall 232 of the parallel walls (or a portion thereof) without holes or slot openings. The sound-absorbing material can be selected from a compressed mineral wool or a melamine foam.

[0080] In a preferred embodiment, each of the parallel walls 230, 232 and the spacers 216 consists of a gypsum board. Walls and / or spacers of another material are also conceivable.

[0081] In an embodiment, the parallel walls and spacers are glued to form the double-walled panel.

[0082] Alternative and equivalent embodiments of the present invention are conceivable, as will be clear to the person skilled in the art. The scope of the invention is only limited by the appended claims.
