Description

[0001] The invention relates to an interior partition wall with a layered structure, wherein the interior partition wall is designed and intended to dampen airborne sound and impact sound.

[0002] It is known from industrial practice that interior partition walls are constructed with a wooden frame consisting of vertically and horizontally oriented frame elements, which span a frame plane and are clad on both sides with panel-shaped sheathing elements, whereby mineral or fibrous insulating materials are used within the wooden frame to reduce airborne and impact sound. It is also known from industrial practice that such interior partition walls are designed with differently structured layers, by means of which improved airborne or impact sound insulation is sought, whereby the insulating layers arranged within the wooden frame are often in the form of flat, homogeneous panel or mat structures.

[0003] As is well known, homogeneously formed insulation panels within a wooden frame allow for simplified installation, but in combination with simple sheathing layers they only achieve limited sound insulation values ​​because the acoustically effective mass and the internal damping of the layer structure are insufficient.

[0004] To achieve the required fire protection values, either several additional outer layers or single outer layers with a high wall thickness are currently needed. This leads to unintentionally high overall thicknesses of the inner wall and thus a loss of interior space.

[0005] The necessary use of thick layers of rock and / or mineral wool for good thermal insulation also leads to high wall thicknesses of the interior wall.

[0006] Therefore, the object of the invention is to provide an interior partition wall that is space-saving, sound-insulating, and fire-resistant. This object is achieved according to the features of claim 1.

[0007] This is an interior partition wall with a layered structure, designed and intended to dampen airborne and impact sound. A wooden frame with vertically and horizontally oriented frame elements spanning a single frame plane serves as the basic framework. At least one planar component extending parallel to the frame plane is connected to the wooden frame, and the interior of this planar component contains channels filled with granules.

[0008] The interior partition wall has a multi-layered structure, which achieves improved airborne sound insulation and / or impact sound insulation compared to known interior partition walls, because a flat building element is connected to the wooden frame, which has an interior space with granule-filled channels and thus provides a defined, essentially uniformly distributed surface mass across the wall surface.

[0009] The channels formed within the planar building element, filled with granules, ensure precise guidance and storage of the granules, as well as a defined adjustment of the surface mass and internal damping of the layered structure. This allows for the fulfillment of increased requirements for airborne and / or impact sound insulation with a structurally simple interior partition wall that offers reproducible acoustic properties. High thermal insulation values ​​are also achieved in this way.

[0010] The interior partition wall has a wooden frame consisting of frame elements extending vertically and horizontally, forming a rectangular or square frame structure lying in a single frame plane. It is intended for use as an interior partition wall within a building. The planar component is designed as a plate-shaped element that extends essentially parallel to the frame plane and can be positioned on both sides of the wooden frame. It is connected to the wooden frame across its surface and defines a closed interior space containing several adjacent channels with essentially uniform cross-sections.

[0011] In a further advantageous embodiment of the interior partition, it is proposed that the vertically extending frame elements of the wooden frame consist of several stud elements running parallel to each other and separately from each other.

[0012] It is proposed here that the vertically running frame elements of the wooden frame consist of several parallel and separate stud elements, by means of which an improved design of the load-bearing wooden frame in the frame plane and a design of the interior partition wall adaptable to different acoustic requirements are made possible.

[0013] The structure described herein, with several parallel and separate support elements, is advantageous in that, by means of the increased number of support elements and the individual cavities formed between the support elements, a defined coordination of the area-related mass, the bending vibration properties of the interior partition wall and the internal damping of the layer structure is achieved, so that increased requirements for airborne sound insulation and / or impact sound insulation can be met with an interior partition wall that is structurally comparatively simple and reproducible with regard to its acoustic properties.

[0014] It is proposed here that the vertical frame elements of the timber frame consist of several parallel and separate stud elements. This results in the sound waves penetrating the timber frame being interrupted by slit-like gaps between each pair of stud elements and thus not being transmitted further. This leads to a further increase in sound insulation.

[0015] According to an advantageous embodiment, a frame element connected to the upright elements on the upper side and a sill element connected to the upright elements on the underside are each one piece and represent the horizontally extending frame elements.

[0016] These horizontally extending frame elements provide a force-fit and dimensionally stable connection of the stud elements in the vertical direction, as well as a load-distributing frame structure. The single-piece design of these horizontally extending frame elements results in improved transfer of vertical and horizontal loads compared to multi-part head and sill constructions, as well as increased overall stiffness of the timber frame. This reduces geometric tolerances and joint formation within the layered structure, and ensures that the surface mass and bearing capacity of the planar building element, which is crucial for airborne and / or impact sound insulation, remains essentially constant across the wall surface.

[0017] It is proposed here that rock wool elements be arranged within the wooden frame, filling at least some of the interior space spanned by the frame elements. The rock wool elements are adapted to the geometry of the wooden frame, ensuring a virtually gap-free and uniform covering of the wall surface. This provides a consistent local mass per unit area and increased internal damping of heat and sound. The flat rock wool elements act as a sound-absorbing and vibration-damping intermediate layer within the layered structure, because the open-pore structure of the rock wool converts sound energy into heat and attenuates vibrations of the adjacent layers.

[0018] It is proposed here that flat mineral wool elements are arranged within the timber frame, resting on the flat rock wool elements and together forming a multi-layered mineral fiber insulation layer. The mineral wool elements are adapted to the geometry of the timber frame and the position of the rock wool elements, ensuring essentially complete and virtually gap-free coverage of the rock wool elements with mineral wool and providing a largely uniform local mass across the wall surface.

[0019] The mineral wool elements arranged on top of the rock wool elements act as an additional sound-absorbing layer. This layer, through a graduated pore structure of both the rock wool and mineral wool elements, provides increased internal damping and improved conversion of sound energy into heat. Furthermore, it is proposed that the combination of the rock wool elements with the mineral wool elements arranged on top of them results in improved decoupling of the vibrating layers of the structure, thus achieving improved airborne and / or impact sound insulation compared to conventional interior partition walls.

[0020] It is proposed here that at least one OSB panel, as a flat panel, is arranged directly on the wooden frame, which, by means of an extension running parallel to the frame plane, provides a flat stiffening of the wooden frame and enables a stable support of the layers arranged within the wooden frame.

[0021] The OSB panel is bonded to the frame elements and, together with them, provides increased flexural and shear stiffness of the layered structure compared to known interior partition walls, because the OSB panel acts as a load-distributing diaphragm and reduces local deformations of the wooden frame, thus ensuring a substantially consistent position of the planar building element with the granule-filled channels as well as the rock wool and mineral wool elements, and achieving increased airborne sound insulation and / or impact sound insulation compared to known interior partition walls.

[0022] It is proposed that a GKF panel be arranged as a planar GKF panel on an outer side of the planar building element, which extends parallel to the frame plane and is completely in contact with the outer side of the planar building element.

[0023] The GKF board, as a board consisting of gypsum plasterboard fiber material, provides an increased area-related mass and high flexural stiffness compared to the insulation materials arranged within the wooden frame, so that an outer layer of the layer structure is formed that is effective for airborne sound insulation and / or impact sound insulation.

[0024] It is proposed here that the OSB board be positioned between the mineral wool elements and the planar structural element, with the OSB board lying flat against the mineral wool elements and extending parallel to the frame plane. It is further proposed here that the OSB board positioned between the mineral wool elements and the planar structural element acts as an additional load-distributing and stiffening layer, thereby ensuring a substantially constant relative position of the mineral wool elements to the planar structural element.

[0025] The OSB board covers the mineral wool elements and is screwed or otherwise attached to the frame. The OSB board, positioned between the mineral wool elements and the flat building element, can also provide increased mass per unit area in the immediate vicinity of the granule-filled channels of the flat building element, thus achieving a pronounced mass-spring effect from the combination of the OSB board, mineral wool elements, and granule material. This results in improved airborne sound insulation and / or impact sound insulation.

[0026] In its erected state, the interior partition wall has a layered structure on the left side according to an embodiment as defined in claims 1 to 8 and the same layered structure on the right side in a mirrored order, wherein the layered structure on both sides comprises the combination of wooden frame, rock wool elements, mineral wool elements, OSB board, sand-filled planar building element and GKF board in this order viewed in cross-section from the inside out.

[0027] The granules are formed as sand, preferably quartz sand, which is arranged within the channels of the planar building element and, by means of its increased bulk density compared to conventional insulating granules, provides an increased area-related mass of the interior partition wall, so that improved airborne sound insulation and / or impact sound insulation is achieved compared to known interior partition walls.

[0028] It is further proposed that the planar component with the channels be made of cellulose, whereby the cellulose provides a flexible, fibrous and vibration-damping bearing for the sand filling held in the channels, so that a pronounced mass-spring effect arises from the combination of sand granules and cellulose structure and increased internal damping as well as a broadband reduction of airborne and impact sound is provided.

[0029] It is proposed here that the GKF board be designed as an externally plastered GKF board, which provides a continuous plaster layer on an outside of the interior partition wall facing away from the GKF board and enables a wall surface that can be used directly from the room.

[0030] It is further proposed that the externally plastered gypsum fiberboard provides an additional mass and stiffness layer on the outside, by means of which improved airborne sound insulation and / or impact sound insulation is achieved compared to an unplastered gypsum fiberboard, and a mechanically resilient wall surface is formed that is resistant to impacts and surface damage.

[0031] Further advantageous embodiments will become apparent from the figures in conjunction with the following description.

[0032] This shows: Fig. 1: Interior partition wall according to an embodiment of the invention in perspective view; Fig. 2: in an exploded view, the interior partition wall according to Fig. 1; Fig. 3: a wooden frame of the interior partition wall with first layer; Fig. 4: Wooden frame according to Fig. 3 with a second layer; Fig. 5: Wooden frame according to Fig. 4 with third layer; Fig. 6: Wooden frame according to Fig. 5 with a fourth layer; Fig. 7: Wooden frame according to Fig. 6 with fifth layer; Fig. 8: Perspective section view of the fourth layer, Fig. 9: in a perspective sectional view, a further embodiment of the invention, and Fig. 10: in a cross-sectional view the interior partition wall according to Fig. 9.

[0033] In Fig. Figure 1 shows an interior partition wall 1 in a perspective, partially cut-away view, in which a wooden frame 2 is visible, which defines the basic geometric structure of the interior partition wall 1 and essentially has rectangular frame openings into which rock wool and mineral wool elements are inserted.

[0034] The wooden frame 2 has 32 vertically parallel upright elements 8a and 8b, which are separated from each other by a continuous slot-like opening in order to prevent sound transmission through this opening.

[0035] While the upright elements 8a and 8b are set up separately, the sill element 6 of the wooden frame 2 arranged on the underside and an element 7 of the wooden frame 2 arranged on the topside are not two-part, but one-part.

[0036] Both the frame element and the sill element 6 run in a horizontal direction 4 and together with the upright elements 8a and 8b form a closed frame made of wood in the form of a wooden frame 2.

[0037] A detailed description of the layer structure of the interior partition according to the invention, as per one embodiment of the invention, is given in the following description in conjunction with Fig. 2 stands out.

[0038] In Fig. Figure 2 shows an exploded view of the layer structure of the interior partition according to one embodiment of the invention in perspective. It must be emphasized that the Fig. The layered structure shown in image 2 represents only one side of the wooden frame and thus one side of the living space. Normally, the same layered structure is mirrored, i.e., arranged in reverse order, on the other side of the wooden frame, i.e., on the right side when viewed in the image plane.

[0039] This illustration shows that the wooden frame 2 first accommodates rock wool elements 30, which have a corresponding fit, and mineral wool elements 31, which also have a corresponding fit, in recesses. Subsequently, these rock wool and mineral wool elements are covered with an OSB board 32, which can be one piece or multiple pieces, the OSB board 32 being attached to the wooden frame 2, for example by means of screws.

[0040] As a further layer in the horizontal direction 4, a plate filled with granules, in the form of sand, is arranged as a planar building element 11. This plate can consist of several individual plates, with all plates lying within one plane with respect to a frame plane 5.

[0041] These flat building elements are filled with sand and are placed in Fig. 8. They are described in more detail. They consist preferably of cellulose material.

[0042] Finally, a GRP panel 33 is installed, which can advantageously be plastered without any problems or simply painted.

[0043] All described layers, panels, and other elements are aligned parallel to a frame plane 5 of the wooden frame and connected and fastened together. This fastening can be done by gluing, screwing, or other fastening methods.

[0044] In Fig. Figure 3 shows a perspective view of the wooden frames 2 with rock wool elements 30 inserted therein. These rock wool elements 30 are arranged within individual segments 8d, which are separated by vertical struts 8c.

[0045] In Fig. 4 shows a further second layer 31, which is placed on the wooden frame according to Fig. 3 has been applied.

[0046] This layer 31 consists of individual mineral wool segments or mineral wool elements that can be inserted just as precisely into the recesses 8 of the wooden frame.

[0047] According to Fig. 5 is a third layer consisting of an OSB board 32 or a plurality of OSB boards 32 on the structure according to Fig. 4 applied.

[0048] These OSB panels 32 cover individual recesses or segments 8d of the wooden frame 2 and thus the mineral wool elements 31.

[0049] In Fig. 6 is a fourth layer, a planar cellulose sheet 11 filled with granules, which preferably consists of several individual sheet elements 11a, all arranged in one plane. This fourth layer is located on the Fig. 5 shown third layer attached. This cellulose board is attached with reference to Fig. 8 described in more detail.

[0050] In Fig. 7 is the fifth layer, in which one or more GRP plates 33 are arranged on the fourth layer according to Fig. 6. This GRP plate forms the outer edge and thus the outer layer.

[0051] In Fig. Figure 8 shows a planar building element 11 in cut-open form in a perspective cross-sectional view.

[0052] This sketched, board-shaped, flat sound insulation panel 11 has an interior space 15 between a lower cover layer 12 and an upper cover layer 13, traversed by parallel longitudinal channels 14. When the sound insulation panel 11 is installed vertically, the longitudinal channels 14 run horizontally. They are bounded from each other by longitudinally extending, undulating support structure elements 16, the apex lines 17 of which abut the inner surfaces of the cover layers 12 and 13, respectively.

[0053] The present arrangement is a two-layer support structure element arrangement, namely on both sides of a separating layer 18 extending parallel to the cover layers 12, 13. However, a three-layer arrangement with two separating layers running parallel to each other is preferably used in order to improve stability, sound insulation and thermal insulation.

[0054] The sketch shows an example of two support structure elements 16 with an approximately triangular cross-section. Likewise, these support structure elements 16 can also have an approximately sinusoidal cross-section or meandering, hollow cuboid cross-sections.

[0055] The cover and separating layers 12, 13, 18 and their supporting structural elements 16 consist of lightweight, thin materials, in particular cellulose. The apex lines 17 of the supporting structural elements 16 are positively or, preferably, materially bonded to the adjacent cover and, if applicable, separating layers 12, 23, 18, and in particular bonded in a moisture-resistant manner.

[0056] The ready-to-use sound insulation panel 11 is hermetically bonded all around with wet-resistant edge tape 19 (adhesive tapes pulled over the edges), preferably under the application of wet-resistant protective layers 20 to at least one of the outer surfaces of the two cover layers 12, 13.

[0057] The longitudinal channels are filled with sand 21.

[0058] In Fig. Figure 9 shows a further embodiment of the invention in a perspective sectional view. The construction of this interior partition shown differs from the construction according to the Fig. 1 - 8 in that a reduced wall thickness is present. This is achieved by offsetting vertically running stud elements 38a and 38b laterally from each other and arranging them almost one behind the other, resulting in a reduced overall thickness of the wall element.

[0059] In comparison with a Fig. In the cross-sectional view of this interior partition wall shown in Figure 10 according to a further embodiment, it becomes clear that the support elements 38a and 38b are arranged one behind the other when viewed in the longitudinal direction of the wall.

[0060] The stud elements 38b are connected to each other across their surface by an OSB panel 42. The stud elements 38a are likewise connected to each other on the other side of the wall by an OSB panel 42. However, it should be emphasized that the OSB panels 42 do not have the actual structural connection function of the stud elements; instead, the stud elements 38a and 38b are additionally connected to each other on both their top and bottom sides by means of frame elements (not shown in detail here) to form a timber frame.

[0061] This type of interior partition design allows the left and right sides to be essentially slid into one another, significantly reducing the overall thickness of the partition. This results in considerable savings in the amount of interior space required for installing such partitions.
