    Description: The invention relates to a prefabricated structural element made of wood according to the preamble of patent claim 1 and to an acoustic wall and acoustic ceiling system according to claim 9.
    In the construction of buildings, especially buildings for schools, restaurants or public spaces, acoustics is a major problem. In particular, when the floors in such buildings have a smooth surface, such as stone slabs or wood flooring.
    Various products for the insulation of the sound are known from the prior art. On the one hand, sound insulation panels made of fibrous materials can be hung under existing ceilings, which usually have a rough surface. Also known are ceiling panels made of wood, which consist of parallel side by side boards, between which sound-absorbing elements are used. Such a wooden ceiling is known from DE 10 2014 000 686 A1. In this so-called dowel wood ceiling, the upright boards are provided with lateral grooves, in which the sound-absorbing elements are used. Above the sound-absorbing elements, the side cheeks of the boards are full of each other and are held together by dowels. Below the sound-absorbing elements, the boards are narrower, so that a slot open from below is produced. Below the sound-absorbing elements, a flow is also inserted, which prevents fibers from the sound-absorbing element from falling down through the slot. A similar construction, which is designed as a wooden ceiling element or as a wooden wall element, is known from EP 2 196 592 B1. In this element, wood boards are arranged side by side analogous to the above-mentioned embodiment and connected by wooden dowels. Even with this wooden ceiling sound insulation elements are inserted in lateral grooves on the boards. Slots in the boards allow the sound to enter from below into the soundproofing elements, where the sound is ultimately absorbed.
    In a further embodiment of a wood prefabricated element according to EP 2 080 845 B1 sound insulating elements are inserted between rectangular boards, which extend either over the entire height of the boards or only over a partial area. In one embodiment, individual boards are shifted upwardly with respect to the adjacent ones and project beyond the upper edges of the adjacent boards and sound insulation elements. Below the respective upwardly shifted boards, this results in a groove formed laterally by soundproofing elements. This is intended to dampen the sound waves entering the grooves.
    A satisfactory solution of the acoustic problem is not disclosed.
    An object of the present invention is to provide a prefabricated device with the highest possible degree of sound absorption. A further object is to provide a component with which a load-bearing ceiling can be created at the same time, ie. The device should not only have optimal sound absorption properties, but be suitable directly as a ceiling or supporting element for a floor above. A further object is the provision of a component which, on the one hand, has optimum sound absorption properties and, on the other hand, is suitable as permanent formwork with static properties for a concrete floor to be created above it.
    Another object of the invention is to provide an acoustic wall and acoustic ceiling system for school and seminar rooms, which on the one hand ensures optimal sound insulation and on the other hand does not suppress the audibility of the voice of lecturers.
    This object is achieved by a prefabricated component according to the features of the claims 1 and 9. Advantageous embodiments of the device are described in the dependent claims.
    With the inventive arrangement, an acoustic component can be achieved with optimal sound absorption or sound absorption. At the same time, the component has a high load-bearing capacity when used directly as a ceiling or as a permanent formwork for a wood-concrete composite ceiling. The desired sound absorption can be adapted to the respective requirements by the ratio of the width of the boards and the width of the sound-absorbing panels in between. Another adaptability is through the choice of the vertical extent of the plates between the boards.
    By appropriate choice of the width and height of the plates, which take over the absorption of sound waves, the device can be adapted to the given circling circumstances. By additionally arranged between two adjacent boards below the plate lying therebetween porous body, further advantages can be produced, namely of the loose fibers existing plates by any shocks peeling fibers are retained and can not get into the room and on the other hand can already by Part of the sound waves are absorbed by the porous body. An intervening space prevents the direct transmission of vibrations of the porous body, if any, to the lower face of the plate.
    By inserting a metal plate over the porous body, which is visible from the outside, the sound, in particular the sound of voices instead of absorbed, is now reflected on the otherwise sound-absorbing components. This makes it possible to create a ceiling or wall paneling that is designed to be completely uniform throughout the space, but to reflect on the speaker's voice and to pass it on to the listeners while at the same time silencing sounds from the audience area. The acoustics system is simple in design, laying over the speaker plates with reflective inserts and the remaining areas of the room with sound-absorbing panels with the same look.
    Reference to illustrated embodiments, the invention will be explained in more detail. Show it:
    1 shows a vertical section through a narrow component with three boards. Plate spaced from the porous end body,
    2 shows a vertical section through a component with plates between the boards with the same width as the boards and plates, which rest on the closing body,
    3 shows a vertical section through a further component in which the ratios of the height to the width is substantially greater than in FIGS. 1 and 2,
    4 shows a vertical section through a further component in which the plates rest on the porous body,
    5 shows a vertical section through another component with a plate made of a further sound-insulating material with a height in relation to the width of the plate,
    6 shows a vertical section through another component with a plate made of a further sound-insulating material with a large width in relation to the height of the plate,
    7 is a perspective view of a device,
    Fig. 8 is a schematic representation of a room with a ceiling according to the invention and Fig. 9 is a vertical section through a component with a reflector plate.
    In the figures, reference numeral 1 designates a prefabricated component. The component 1 comprises a plurality of vertically arranged boards 3, which consist of solid wood. The boards 3 have a width a and a height h. Further, the boards 3 are spaced along the side surfaces in the region of the lower edge 5 spaced to the latter on both sides rectangular grooves 7 inserted. The grooves 7 have a depth c and a base width d. The grooves 7 are at a distance e from the edge 5. Each board 3 is thus provided on both sides with a groove 7 and has as a whole a rectangular cross-section which extends from the lower edge 5 to the upper edge 9.
    Between the boards 3 arranged side by side constructed of organic or inorganic fibers sound-absorbing plate 11 is used. The also having a rectangular cross-section plate 11 extends between the upper edge 9 and the upper edge c of the groove 7, preferably the plate 11 terminates at a distance above the groove 7. Preferably, the above-lying coming free surface of the plate 11 is slight set back from the upper edge 9 of the board 3. The lower end face 15 of the plate 11 can, as shown in FIGS. 1 and 2, be aligned with the upper edges c of the grooves 7 (FIG. 4) or, as can be seen in FIGS. 1 to 3 and 6 and 7, offset upwards to lie.
    Between the opposing grooves 7 each two adjacent boards 3, a porous body 17 is inserted. In the embodiments of the invention according to FIGS. 1 to 3 and 5 and 6, the upper surface of the body 17 is spaced from the lower end face 15 of the plate 17, so that between the body 17 and the plate II, a gap 19 is formed. The body 17 may extend over the entire height or width d of the base of the groove 7; it may also rest only on the lower side edge c of the groove 7 and have a thickness which is smaller than the basic width d of the groove. 7
    The connections between the parallel adjacent boards and the boards 3 and plates 11 arranged therebetween are effected by wooden dowels 21 shown schematically in the figures. The wooden dowels 21 can be arranged penetrating either board 3 to board 3 and the plate 11 or preferably over a larger number, eg six boards 3 and five plates 11 extend. The insertion of the dowels 21 takes place by drilling the stacked boards 3 and plates 11 and by pressing a correspondingly long dowel 21, for example made of beech wood. Such assembled boards 3 and plates 11 are close together and need no further connection, for example with a glue. Along the boards 3 and plates 11, which may extend over a few meters, dowels 21 are inserted at regular intervals. Alternatively, the elements can also be mutually connected only with glue or by a screw connection. An example of a gluing or screwing is not shown. The porous body 17, which are inserted between the grooves 7, there may be loose or, if the device is used as a wall element use, are held immovably by a glue layer in the grooves 7, so that the body 17 can not slide by its own weight down , Especially when the device is exposed to vibrations 1.
    The plates 11, which are preferably made of a fibrous material, such as wood fiber or inorganic fibers made of stone or glass, serve to absorb noise from the room in which the components 1 are arranged as ceiling elements and / or as wall elements. The porous bodies on your part also act as sound insulation and on the other hand they prevent loose fibers from escaping from the overlying fibrous plates 11 and falling to the floor. In addition, 17 can produce optical effects with the color design of the porous body, which interrupt the surfaces of the components used as wall or floor elements 1.
    If the plate 11, which comes to rest between two boards 3, has the same width b as the width a of the boards 3, the absorption volume of the body 11 is able to reach an absorption factor of 0.75. This can be achieved in particular because the cross section of the plate 11 corresponds to the cross section of the opening between the lateral edges of the boards 3. A somewhat lower degree of absorption of Y is achieved if the width b of the plate 11 corresponds to about half the width a of the board 3. The high degree of sound absorption A can be achieved when the plate 11 extends substantially over the entire height of the board 3, which lies above the grooves 7.
    As optimum values for the dimensions of the boards 3 and the plates 11, the following values have resulted: a 30 mm to 60 mm, preferably 40 mm; Height h 100 mm to 300 mm, preferably 160 mm to 260 mm.
    Fig. 9 shows a vertical section through a prefabricated component 101, whose structure corresponds to those components, as shown and described in FIGS. 1 to 7. In contrast, a reflector plate 123 is inserted over the porous body 7 in this embodiment. The reflector plate 123 can rest directly on the porous body 17 and at the same time on the underside of the plate 11th
    Alternatively, there may be a gap between the reflector plate 123 and the porous body 17 and / or the plate 11.
    In this embodiment of the invention, the porous body 17 is essentially only the optics, that is, the view of the device 101 corresponds exactly to those that have been described in FIGS. 1 to 7. The reflector plate 123 itself has the object here, e.g. In a school or seminar room, the language of a lecturer sitting or standing under the component 101 not or only to dampen, but to reflect on the ceiling and / or the walls in the audience. For this reason, the reflector plate 123 is preferably made of metal with a smooth surface.
    In Fig. 8 is denoted by the letter A, the sound or voice source and the arrows P represent schematically the acoustic waves of a speaker's voice. The area of the ceiling with the hatched area is covered with components 1 according to claims 1 until 6; the central area with simple hatching represents the components 1 with reflective inserts according to FIG. 9 and claims 7 and 8.
    Such no longer sound-absorbing components 101 are arranged in school and seminar rooms in the area above, possibly also adjacent to the areas where the speaker or the speakers, so that the language is reflected on the device 101 and to the listener in the Room is forwarded. However, noises caused by the listeners in the room or from outside the room are absorbed by the remaining components 1 without reflecting plates 123. By this measure, the volume of the speakers speaking people can be maintained and at the same time noise from the room and from the outside can be suitably insulated.
