    专利说明:

    The invention relates to a ceiling element, which is preferably made of wood-based materials and is intended for mounting a ceiling, with a back layer that delimits at least one cavity, and with a visible layer below.
    Ceiling elements made of wood-based materials have already been created with which storey ceilings can be installed in buildings. A ceiling element of the type mentioned at the outset is known, for example, which has a back layer that delimits at least one cavity (see https://www.lignotrend.de/produkte/zertIERTebauteile/ B01-decke-mit-Holzunteransicht /). A pressure distribution plate is provided on the back sheet to support the floor structure. On the flat side of the pressure distribution plate facing away from the floor structure, cross-laminated timber rib elements that are spaced apart and arranged parallel to one another are glued, with rib elements that are adjacent to one another each laterally delimiting an interior space that can be filled with a weight filler for impact sound insulation. With such a weight bed, the absorption behavior with regard to the impact sound effects is to be improved by applying additional masses in the load-bearing cross-section and a suspended ceiling is to be supported or replaced for the same purpose. The rib elements laterally delimiting the cavity have a transverse layer on their downward-facing end face facing away from the floor structure, which is also intended to increase the dimensional stability of the previously known ceiling element. On the visible side of this transverse layer, an underlying visible layer is applied, which can have a layer made of solid wood or veneered wood materials as a closed surface or an acoustic profile made of mutually spaced, parallel slots.
    It has been shown, however, that the protection against impact sound transmission in the previously known ceiling elements is still in need of improvement, especially in the low-frequency range.
    [0004] The object is therefore to create a ceiling element of the type mentioned at the outset that is characterized by improved impact sound insulation, especially in the low-frequency range.
    The inventive solution to this problem consists in the ceiling element of the type mentioned in particular that the visible layer is penetrated by at least one open joint on the visible side, which opens into the at least one cavity.
    The ceiling element according to the invention has a back layer which delimits or encloses at least one cavity. The ceiling element according to the invention also has a visible position below, which determines the view from the floor below onto the ceiling element according to the invention. The visible layer is penetrated by at least one joint that is open on the visible side and opens into the at least one cavity. The ceiling element according to the invention does not use the effect of a Helmholtz resonator to improve the room acoustics, but rather it is adjusted to the low-frequency range. Since the reserve delimits or encloses at least one cavity, this impact sound insulation is built into the load-bearing ceiling cross-section and an additional suspension height is avoided. The ceiling element according to the invention is thus characterized by an efficient ceiling cross-section with a low element height and, at the same time, by improved impact sound insulation. In this way, an improvement in the subjectively perceived impact noise is achieved without affecting the room acoustics.
    In order to be able to adapt the design and structure of the ceiling element according to the invention to the disturbing low-frequency area and, for example, to detect the sound insulation in the range between 50-100 Hz, the at least one cavity in the ceiling element according to the invention can be in terms of its cavity height, width and cavity -depth can be adjusted and coordinated accordingly. Several cavities are also possible in each individual ceiling element. An adaptation of the ceiling element according to the invention to the disturbing low-frequency range is also possible through the coordinated and selected characteristics of the joints and through their number and spacing. By variably adapting the joints to the frequency to be absorbed, it is possible to adapt the absorption depending on the ceiling element and element structure.
    Thus, a preferred embodiment according to the invention provides that the at least one cavity has a width and / or depth that measures more than twice compared to the depth of the joint.
    It can be advantageous if the at least one cavity has a longitudinal extent which is more than twice as long as the length of the at least one joint opening into this cavity.
    The ceiling element according to the invention is characterized by optimized impact sound protection in the low-frequency range, the room acoustics not being impaired thereby. For aesthetic reasons and / or to improve the room acoustics, it can be advantageous if the visible layer has a closed surface or an acoustic profile on the visible side.
    An aesthetically pleasing embodiment according to the invention, which can also be made aesthetically very pleasing, provides that the acoustic profile is formed by slits on the visible side and preferably parallel to one another in the visible position.
    A preferred embodiment according to the invention, in which the slots serving as acoustic profiling can be easily introduced into the visible layer without the ceiling structure being weakened as a result, provides that the visible layer is connected to the back layer via a transverse layer.
    An embodiment is preferred in which the transverse layer is formed from strips that are spaced apart from one another and are preferably arranged parallel to one another, in particular from solid wood strips.
    In order to further promote the sound-absorbing effect of this acoustic profiling on the visible side, it can be advantageous if a sound absorber made from a plurality of fibers or chips, in particular wood wool, is provided in the space between adjacent strips of the transverse layer. So that the ceiling element according to the invention can function as a Helmholtz resonator without the visible joints opening into the at least one cavity being recognizable, it can be advantageous if the at least one joint leads from an assigned slot in the acoustic profile to the at least one cavity .
    An effective and aesthetically pleasing embodiment according to the invention provides that at least two spaced apart joints lead from the associated slot to the at least one cavity.
    So that the ceiling element according to the invention also has a high load-bearing capacity and resilience, it is advantageous if the back layer is made of cross-laminated timber or glued laminated timber.
    A particularly advantageous embodiment according to the invention provides that the rear layer has a pressure distribution layer facing away from the visible side of the ceiling element and arranged parallel to the ceiling plane, which pressure distribution layer is connected at right angles to at least two axially parallel and spaced apart side boards or ribs, which are connected between them delimit the at least one cavity. These side walls, which are glued to the pressure distribution layer of the back layer, preferably made of cross-laminated timber, form statically load-bearing cross-sections which additionally stiffen and reinforce the ceiling element according to the invention and its pressure distribution layer.
    [0018] Further developments according to the invention emerge from the drawing in conjunction with the claims and the description. The invention is described in more detail below with reference to preferred exemplary embodiments.
    1 shows a ceiling element in a cross-section arranged transversely to the longitudinal extension of the ceiling element, FIG. 2 shows the ceiling element from FIG. 1, shown here shortened in its longitudinal extension, in a longitudinal section, FIG. 3 another Embodiment of a comparable designed ceiling element in a cross section, FIG. 4 shows a further embodiment of a ceiling element, shown in a cross section, which is configured in a manner comparable to the ceiling elements according to FIGS. 1 to 3, and FIG. 5 shows a further, cross-sectional embodiment of a ceiling element, which is designed in a comparable manner in comparison to the ceiling elements according to FIGS.
    1 to 5 different versions 1, 3, 4 and 5 of a ceiling element are shown in different views, which is preferably made of wood materials and intended for mounting a ceiling in a building not shown here. The ceiling elements 1, 3, 4 and 5 have a back layer 2 which delimits at least one cavity 6. The ceiling elements 1, 3, 4, 5 also have a visible layer 7 below, which determines the view of the ceiling element 1, 3, 4, 5 from the floor below.
    In FIGS. 1 to 5 it can be seen that the visible layer 7 is penetrated by at least one joint 8 which is open on the visible side and which opens into the at least one cavity 6. The ceiling elements 1, 3, 4, 5 shown here do not use the effect of a Helmholtz resonator to improve the room acoustics to absorb the impact sound in the ceiling in the reception room. The ceiling element can be adjusted to the frequency range to be absorbed by the dimensions of the at least one cavity 6, the cross-sectional shape of the joint 8 and the joint width, the joint length and the distance between adjacent joints 8, in particular those leading to a common cavity 6. The depth of the joint must be adapted to the structural height to be penetrated in the ceiling element 1, 3, 4, 5 in the area of the exposed layer 7.
    From the longitudinal and cross-sections in FIGS. 1 to 5 it is clear that the at least one cavity 6 has a width and / or depth which is more than twice that of the joint depth A. It can also be seen that the at least one cavity 6 has a longitudinal extent which is more than twice that of the joint length D of the at least one joint 8 opening into this cavity 6. In FIG. 1 it can be seen that the joints 8 have a comparatively small joint width C. While the joint 8 on the left in FIG. 1 has joint side walls which run approximately parallel to one another, it can be seen in the joint 8 on the right in FIG. In FIG. 2 it can be seen that the joints 8 leading to a common cavity 6 and arranged here approximately on a line can be arranged at a joint spacing E from one another.
    From a comparison of FIGS. 1 to 4 on the one hand and FIG. 5 on the other hand it can be seen that the visible layer 7 of the ceiling elements 1, 3, 4, 5 on the visible side has a closed surface (see FIG. 5) or an acoustic profile ( see. Fig. 1 to 4). The acoustic profile of the ceiling elements 1, 3, 4 shown in FIGS. 1 to 4 can be formed by slits 9 on the visible side and preferably parallel to one another in the visible layer 7, which is made of solid wood or veneered wood materials.
    The back layer 2 of the ceiling elements 1, 3, 4, 5 is here made of cross laminated timber. The back sheet 2 has a pressure distribution layer 10 facing away from the visible side of the ceiling element 1, 3, 4, 5 and arranged parallel to the plane of the ceiling element 1, 3, 4, 5, which can support the floor structure not shown here. At least two axially parallel, spaced apart ribs or side boards 11 arranged at right angles to the pressure distribution layer 10 are glued to the pressure distribution layer 10 and delimit the at least one cavity 6 between them. These side boards or ribs 11 can also delimit or enclose further cavities 12, which are provided, for example, as installation channels and in which no joints 8 open on the visible side open. Since the side boards 11 delimit at least the at least one cavity 6, part of the load-bearing ceiling element cross section is activated for this cavity 6. Since there is no need for an additional suspension height, an efficient ceiling cross-section with a low ceiling element height is achieved. Since the side boards 11 support the pressure distribution layer 10, the side boards 11 delimiting the at least one cavity 6 also simultaneously form a statically load-bearing cross section.
    In the ceiling element 5 shown in FIG. 5, the at least one cavity 6 is limited to the visible side solely by the visible layer 7, which is directly connected to the rear layer 2 for this purpose.
    In the case of the ceiling elements 1, 3 and 4 shown in FIGS. 1 to 4, the visible layer 7 carrying the acoustic profile is, on the other hand, connected to the rear layer 2 via a transverse layer 13. This transverse layer 13 can be formed from a plate-shaped wood material or - as here - from strips 14 spaced apart from one another and preferably arranged parallel to one another, in particular from solid wood strips. It can be seen in FIG. 2 that a sound absorber 15 made from a large number of fibers or chips, for example wood wool, can also be provided in the space between adjacent strips 14 of the transverse layer 13. The slitting of the visible layer 7 serving as acoustic profiling can be achieved by simple cuts, the sound absorber 15 located in the intermediate spaces being activated. A faster and more cost-effective joining of the ceiling element 1, 3, 4 is thus also promoted in this area and a complicated or costly joining is avoided. Since the slitting used as acoustic profiling can also be industrially prefabricated, precise and plannable formatting of the ceiling elements is made easier. This applies in a comparable way to the joints 8, which are also worked in as slots. Thus, the ceiling elements 1, 3, 4 and 5 can be formatted in a cost-effective manner at the factory.
