Description

Wall element and wall segment for a soundproof cabin and a soundproof cabin

The invention relates to a soundproof cabin for freestanding construction in the building interior, such as a hall, a large office, a workshop, a recording studio, a dwelling or the like. A soundproof cabin can be used, for example, as a meeting room, telephone booth, acoustic cabin or recording studio. The invention also relates to a wall element for a soundproofing cabin and a wall segment composed of a plurality of wall elements for a soundproofing cabin.

A generic freestanding sound enclosure is suitable for use within a building structure, such as within a open plan office, to provide a room in room that is acoustically separated from the rest of the room so that conversations, such as meetings or telephone calls, within the sound enclosure are undisturbed by the room ambient noise prevailing. Conversely, a soundproof booth may also be provided to ensure that conversations made within the soundproofing booth do not escape outside so as not to disturb the other people in the open-plan office or to prevent sensitive information from being passed on in an uncontrolled manner.

Generic freestanding soundproof booths are generally not integrated into the structure of the building in which they are used. In general, a soundproof cabin is free of any structural or static connection to a building wall and / or building ceiling. Preferably generic sound insulation booths are placed on a flat floor surface in the building interior. Preferably soundproof cabins are equipped free of a bottom anchoring. Preferably, a position assurance, such as an anti-slip means may be provided between a soundproof cabin and a building floor surface. A soundproof cabin is usually equipped with at least one door. A sound enclosure may include one or more windows. The door as well as any windows are preferably soundproofed. From EP 2 481 868 Bi a sound attenuation element is known, which, however, is intended primarily for music in their homes to protect the neighboring apartments of noise. The sound-damping element is composed of a plurality of interconnected panels. The panels are provided with grooves which run around all their edges, so that a strip can be received between two panels which are in contact with each other along their edges. According to EP 2 481 868 Bi, the manufacturing tolerance of the strips and the panels is such that during assembly pressure is generated between the panels and the strips in order to statically hold the sound-absorbing element together. The panels are predominantly rectangular and composed of two opposite surface boards, between which a foam mat is inserted. The connecting strips consist of two wooden blocks and a resilient strip of elastomeric material. The surfaces of the inside boards may additionally be covered with an acoustically damping material such as wool or foam. In a known sound attenuation element, the assembly has been found by four strips in several respects as disadvantageous. First, the assembly is relatively complicated and it takes to build a single sound-absorbing element generally several hours. On the other hand, it is virtually impossible to set a constant gap between adjacent panels, because an attempt to correct the clamping connection between two adjacent panels by means of the interposed spring bar inevitably leads to compression of the held between the boards of a panel foam material. Furthermore, the spring strip provided along the edges of the panels affects the sound-absorbing effect of the entire element, because the spring strips represent sound-transmitting bridges from the inside board to the outside board. It is an object of the invention to provide a wall module, a wall segment composed of several wall elements, as well as a composite of wall blocks or wall segments soundproof cabin for freestanding structure inside the building, which overcome the disadvantages of the prior art, in particular provide a simplified installation with improved sound damping effect , This object is solved by the subject matters of the independent claims.

According to a first aspect of the invention, a wall module for a soundproof cabin for free-standing construction in the building interior, such as a hall, a large office, a workshop or the like is provided. The wall element according to the first aspect of the invention comprises a composite structure comprising a cabin-inside hard plate and a Cabin outer side hard plate, which are opposite to each other, and arranged between the kbinneninnenseitigen hard plate and the cab outside hardboard insulating layer of fiber material. Preferably, the fiber material is a pressed fiber material, in particular a wood fiber material. The cabin interior and / or the cabin exterior hardboard may be a plywood board. The insulating layer of fiber material provides the wall module increased stability. In particular, compared to wall blocks or panels with foam material provided therein, wall blocks invention can be handled easier and easier to assemble. The use of a stable fiber material also simplifies the achievement of a uniform gap between adjacent wall blocks.

According to a preferred embodiment, the insulating layer comprises a fiber material insulation board, in particular a Holzfaserdämmplatte. Particularly preferably, the insulating layer may be an insulating board made of pressed wood fiber. Such insulation boards are particularly ecological, and have excellent properties in terms of acoustic insulation and mechanical stability ready. The insulation board or fiber material insulation board preferably has a thickness between 10 mm and 150 mm, in particular 20 mm to 100 mm, preferably about 40 mm.

Preferably, both the cabin inside hardboard and the cab outside hardboard can each be formed from a plywood board. The hardboard, in particular plywood panel, may be surface-coated, for example painted.

According to a preferred embodiment of a wall module according to the invention, the insulating layer consists of preferably pressed fiber material, in particular wood fiber material. A wall module, which is formed from two opposing hard plates and an existing therebetween consisting of a pressed fiber material insulation layer has been found to be particularly suitable for sound insulation and is particularly dimensionally stable for easy and accurate installation.

According to a preferred embodiment of a wall module according to the invention, the insulating layer may have a density between 100 kg / m ³ and 300 kg / m ³ . Preferably, the insulating layer has a density between 180 kg / m ³ and 220 kg / m ³ , in particular about 200 kg / m ³ . The selection of the insulating layer with such a density, in particular a Insulating layer of pressed fiber material, has been found to be particularly suitable in terms of the combination of mechanical stability and acoustic insulation effect.

According to a preferred embodiment of a wall module according to the invention, the composite structure has a direct adhesive bond, such as an adhesive bond, for example a resin or glue compound, between the insulating layer and at least one inside and outside the cabin side hardboard and / or cabin. By a preferably large adhesive bonding of the insulating layer to one or both hard plates, the other adhering components can be handled simply as a unit and there are no fasteners, such as screws or dowels required, which may affect the acoustic insulation effect of the wall module.

The invention relates according to a second aspect of a wall module for a soundproof cabin for freestanding structure in the building interior, such as a large office, a hall, a workshop or the like. The wall module according to the second aspect of the invention can be combined with the features of the wall module according to the first aspect of the invention. According to the second aspect of the invention, the wall module comprises a cabin-inside hardboard, in particular a veneer panel, and a hardboard outside cabin, in particular a veneer panel, which face each other, and an insulation panel arranged between the hard panels, preferably made of in particular pressed wood fiber material. According to the second aspect of the invention, at least one hard plate and / or the insulating board has a recess. The wall module according to the second aspect of the invention comprises at least one form-fitting element arranged at least partially in the recess for defining a relative position between one of the hard plates and the insulating board. Preferably, the wall module comprises at least three particularly similar positive locking elements for defining a relative position between one of the hard plates and the insulating board. The at least one interlocking element can for example define the relative position between the inside of the cabin hardboard and the insulation board. It is conceivable that the at least one interlocking element defines the relative position between the outside of the cabin hardboard and the insulating board. Preferably, at least one recess for receiving a form-fitting element is provided in the insulation board. Preferably, a plurality of recesses may be provided, for example, in the insulating board and a plurality of form-locking elements (for example, two, three, four or more). The number of interlocking elements per hard plate is preferably less than 100, in particular less than 20, preferably less than 10. Preferably, each recess is exactly one interlocking element assigned. It may be preferred that exactly one recess is associated with each form-fitting element. Surprisingly, it has been found that the use of interlocking elements for defining a relative position between the hard plate and insulation board in a simple manner allows precise production of the individual wall blocks, which ensures that adjacent wall blocks within precise tolerances can be connected together, resulting in particular in the formation of a shows constant gap between adjacent wall blocks. The use of a positive-locking element between only one of the plates and the insulating board preferably ensures that the positive-locking element does not generate a bridge for transmitting sound from the inside of the cab to the outside of the cabin.

According to a preferred embodiment of a wall module according to the second aspect of the invention, the wall module comprises at least a first positive locking element for defining a relative position between the first in particular outside cabin hardboard and the insulating board and at least one other, second positive locking element for defining a relative position between the second inside cabin hardboard and the insulation board. The first, cabin outer-side positive locking element is to be arranged offset in the horizontal direction, in the vertical direction and / or in the transverse direction relative to the second, cabin-side positive-locking element. This refinement improves the precision of the assembly, so that a particularly precise relative position of the hard inner side of the cabin inside the hardboard relative to the outside of the cabin can be realized. By providing a staggered arrangement of the cabin inner-side positive-locking elements for the cabin exterior-side positive-locking element, it is ensured that no sound-transmitting bridge is generated between cabin-side and outer cabin-side hard plates. It may suffice to provide an offset arrangement in only one direction (transversely, vertically or horizontally). Preferably, a staggered arrangement of one or more cabin-inside positive locking elements relative to one or more outer cabinets positive locking elements is provided in at least two or exactly two directions, that is, for example, both in the transverse direction and in the horizontal direction or both in the transverse direction and in the vertical direction or both in the horizontal direction also be in vertical direction. It is clear that the terms "horizontal direction" and "vertical direction" refer to directions with respect to a standing soundproof booth. The transverse direction denotes the direction from the inside of the cabin to the outside of the cabin with respect to a wall module. According to a preferred embodiment of a wall module, both the at least one hard plate and the insulating board each have a recess for the positive-locking element. That is, the at least one hard disk has a hard disk recess and the insulation board has an insulation board recess. The insulation board recess, the hardboard recess and the positive-locking element are dimensioned to match one another. In particular, hard-plate recess, insulation board recess and form-fitting element, which are associated with one another, may be dimensioned complementary to one another. The inner contour of the hard-plate recess may correspond to the outer contour of the positive-locking element. The inner contour of the insulation board recesses can correspond to the outer contour of the form-locking element. In particular, the same inner contours can be provided for the insulation board recess and the hard-plate recess and a positive-locking element with a corresponding outer contour. It is conceivable that mutually paired hardboard and Dämmplattenaussparungen are provided in the opposite cabin inside and outside cabin hardboard and in the intermediate insulating board each paired. As described above, with respect to the interlocking elements or the recesses may be provided offset in the horizontal direction, vertical direction and / or transverse direction arrangement. That is, the cabin outer side recesses between the cab outside hardboard and insulation board and the cabin inside recesses between the cabin inner side hard plate and insulation board can be arranged offset from each other in the horizontal direction, vertical direction and / or transverse direction. Preferably, the depth of the recess can be dimensioned larger in the transverse direction in the insulation board than in the hard plate. Preferably, the hard-plate recesses and / or the Dämmplattenaussparungen are formed as a blind hole so that they are not visible on the outer cabin inside or cabin outside flat side of the wall module.

According to a preferred embodiment of a wall module according to a second aspect of the invention, the positive-locking element has a barb structure for connection to the insulating board. In addition or as an alternative, the form-fitting element and the inside of the cabin or on the outside of the cabin can preferably adhere to one another to form an adhesive bond. Such a configuration is particularly easy to manufacture and easy to install.

According to a preferred embodiment of a wall module according to the second aspect of the invention, the positive-locking element is a pin with an engagement surface of at least 1 cm ² . For example, the pin may have a circular base cross-section. In front- Preferably, the pin can be designed tubular. A tubular pin can in particular be designed with a preferably plate side to be arranged cover portion. The engagement surface of the pin, which is, for example, circular, may have an engagement surface of at least 2 cm ² , at least 4 cm ² or at least 6 cm ² . Preferably, the engagement surface of the pin is smaller than 100 cm ² , in particular smaller than 50 cm ² or even smaller than 25 or 10 cm ² . The circumference of the lateral, in particular barbed, pin peripheral side preferably measures at least 3 cm, at least 5 cm or at least cm and / or at most 20 cm, at most 15 cm or at most 10 cm. The length of the pin is smaller than the width of the wall module in the transverse direction. Preferably, the length of the pin is smaller than half of the wall module in the transverse direction. Particularly preferably, the length of the pin is smaller than the width of the insulation board in the transverse direction. In particular, the length of the pin may be greater than a quarter and / or less than three-quarters of the width of the Dämmplätte in the transverse direction. In addition to a circular engagement surface and other pin cross-sectional shapes are conceivable, for example, triangular, rectangular, in particular square, cross-shaped, star-shaped or the like. Circular pins and corresponding recesses are inexpensive and easy to assemble. The pin may have on at least one end face, for example, the plate-side end face, a flange and / or lid portion to improve a surface connection, for example by means of an adhesive such as an adhesive against a hard disk.

In a preferred development of a wall module according to the first and / or second aspect of the invention comprises a cabin inside and / or outside cabin hardboard having a thickness of 10 mm to 30 mm, preferably about 19 mm. Additionally or alternatively, the cabin inside and / or outside cabin hardboard can span a surface of at least 0.5 m ² , preferably at least 1 m ² and / or at most 9 m ² , preferably at most 4 m ² . Such sized hard plates are particularly well suited for easy assembly handling.

A preferred embodiment of a wall module according to the invention according to the first and / or second aspect of the invention comprises an insulation board, which extends in the transverse direction of the cabin inside hard board to the outside of the cabin hardboard. The insulating layer or insulating board occupies at least 50%, preferably at least 75%, in particular at least 90%, of the area spanned by the cabin inside and / or outside of the cabin hardboard. By the insulating layer or insulation board is completely from the cabin inside hardboard to the cabin outside Hard plate extends and / or occupies a majority of the area spanned by the hard disk surface, a particularly good sound insulation effect with good mounting stability of the wall module is achievable.

The invention also relates to a wall segment, in particular a corner wall segment, for a soundproof cabin for freestanding construction in the building interior, such as a hall, a large office, a workshop or the like. The wall segment comprises two wall blocks. The wall modules can be designed in particular as described above. The wall blocks comprise two hard plates arranged opposite one another, in particular plywood boards, and an insulating board arranged between the two hard boards. The two wall modules are arranged in such a way that at least one hard plate of the first wall module defines a contact area with a hard plate of the second wall module. It is conceivable that two hard plates each of a first wall module and a second wall module define a respective contact area. For example, a cabin-inside contact area can be defined by the cabin-inside hard plates of the first and the second wall module. For example, a cabin-side contact area can be defined by the cabin-side hard plates of the two wall blocks.

In the wall segment according to the invention, at least one fastening part connecting the wall blocks is arranged in the at least one contact region, preferably in the two contact regions. It is conceivable that a plurality of fastening parts are arranged in a contact region. It is conceivable that in each case at least one fastening part is arranged both in a cabin-inside contact area and in a cabin outer-side contact area. The connection on impact preferably relates to two wall units arranged horizontally at even vertical height. A fastening part can be for example a plug-in fastening part for a horizontal assembly movement. It is conceivable that a fastening part is a translatory fastening part with a mounting direction in the vertical direction. For example, can be provided as a fastening part, a releasable fastening part, which allows a preferably tool-free assembly and disassembly of the wall segment or the soundproof cabin. A fastening part may for example comprise a rail component in the first wall module and a groove component complementary to the rail component in the second wall module. The fastening part can have a barb component on the first wall module and a complementary retaining component with recesses for fixing ren the barb component in the second wall brick have. Preferably, the attachment member may be a Owotech connector, for example, type V0930 or type 1240. The Owotech connector is described in WO 2017060334 Ai. The connection of the wall blocks in one or two contact areas of mutually standing hard plates allows a simple, yet stable and precise installation of wall segments or soundproof booths from individual wall blocks. In the fastening parts in the contact area between abutting hard plates, which are used to attach a wall module to another wall module, preferably no fastening part penetrates into the insulating panel (s), so that the sound-damping effect of the insulating panels by the at least one fastening part is not affected is.

According to a preferred embodiment of a wall segment, the wall blocks are connected to each other in abutment such that the end face of the first wall module is perpendicular to a flat side of the second wall module and that the outer flat side of the first wall module in alignment with the end face of the outside of the cabin hardboard of the second Wandbausteins is aligned. Such a wall segment may be a preferred embodiment of a corner wall segment. The outer flat side of the first wall module is preferably provided by the outer flat side of the cabin exterior hardboard of the first wall module. The end face of the outer cabin hardboard of the second wall module is preferably aligned at a right angle to the outer flat side of the second wall module. When the outer flat side of the first wall module is aligned with the end face of the cabin outer side hard plate of the second wall module, the outer flat sides of the first and the second wall module are aligned at right angles to each other.

In another preferred embodiment of a wall segment, the wall blocks are so connected to each other in shock, that the end faces of the wall blocks are in pairs and that the flat sides of the wall blocks are aligned in pairs in alignment with each other. It is conceivable that the end faces of the wall blocks or the end faces of the hard plates, so the cabin outside and the inside cabin hard plates of a wall module, are arranged in a common plane. The outer flat sides of the wall blocks form a composite flat outside of the soundproof cabin. The inner flat sides of the wall blocks form a composite flat inside of the soundproof cabin. Such a wall segment, for example, in a space provided as a meeting room soundproofing cabin along a relative long side wall be provided, so that it is avoided that a single wall module must extend over the entire width of the soundproof cabin.

According to a preferred embodiment of a wall segment, which can be combined with the one described above, the wall blocks are free of connecting means for fastening two wall blocks to each other outside the contact area or the contact areas. In particular, the wall modules on the outside and / or inside of the cabin are free of connecting means, such as fastening parts. In particular, no belts, angle plates or other fittings are provided on the outside of the wall modules or the wall segment or soundproof cabin for connecting two wall units. Preferably, no connecting means or fastening parts are provided in the region of the insulation boards.

According to a preferred embodiment of a wall segment, the fastening part is housed within the connected wall blocks such that the fastening part on the outside (outer flat side and optionally visible front side of the hard disk) and / or on the inside (inner flat side of the inner hard disk) of the wall blocks is invisible.

The invention also relates to a soundproofing cabin, such as a telephone booth, a meeting room, an acoustic cabin, a study studio or the like, for a sound insulation of at least 30 dB, at least 35 dB or at least 40 dB for free-standing installation in a building interior, such as a hall. a large office, a workshop, a recording studio or the like. The soundproof cabin comprises a plurality of wall elements described above with an inner flat side, an outer flat side, two horizontal edge sides and two vertical edge sides, and possibly at least one wall segment. The flat sides of the wall blocks are defined by the outside in the vertical direction and in the horizontal direction broadly extending outside or inside of the wall blocks. For example, an outer surface of the cab outside hard board or an outer surface of the cabin inside hard board may define an inner flat side. The surface of the flat side essentially corresponds to the surface of the inner or outer hard plate of a wall module. A coating, for example a wool, nonwoven and / or felt coating or the like, may be provided on the outer surface of a wall component, that is to say on the outer surface of a hardboard inside or on the outside of the cabin. Preferably, the hard plates are coated with a paint. In the soundproof cabin, the several wall blocks are like that mountable to one another that the insulation board of a first wall module protrudes into another, second wall module. This facilitates the installation and improves the soundproofing function of the soundproof cabin.

According to a preferred embodiment of a sound insulation cabin, the insulation board of the first wall element overlaps the insulation board of the second wall element to at least 50%, preferably up to 75%, in particular completely. Such a configuration is particularly advantageous in the region of a corner wall segment, wherein the corner wall segment can be formed on at least one contact surface as described above or without fastening elements. The invention also relates to another soundproofing cabin, such as a telephone booth, a meeting room, an acoustic cabin, a recording studio or the like, which can be designed as described above and designed for a sound insulation of at least 30 dB, at least 35 dB or at least 40 dB between the cabin interior and the environment is. According to this aspect of the invention, too, the soundproof booth is provided for free-standing installation in a building interior, such as a hall, an open-plan office, a workshop, a recording studio or the like. The soundproofing cabin comprises a plurality of wall units as described above with an inner flat side, an outer flat side, two horizontal edge sides and two vertical edge sides, as well as possibly at least one wall segment as described above. The plurality of wall blocks are mounted to one another along their edge sides in such a way that the insulation boards of two adjacent wall blocks are in surface contact contact with each other. Alternatively or additionally, two adjacent wall modules can be adjacent to one another free of gaps, in particular free of cavities. The plurality of wall blocks may be provided with mounting elements for mounting like a wall segment described above. The surface touch contact may extend over an overlap area of at least 50%, at least 75% or preferably 100%, of the end face of one of the wall blocks. It is preferred that the wall modules free of space, that is, without sections forming a gap, which may be hollow or designed with a non-insulation object such as a pressure bar. By providing a two-dimensional contact contact between the insulation boards of adjacent wall blocks or an interspace-free adjoining arrangement of two adjacent wall blocks, a sound-permeable cavity is avoided and the mounting orientation is clearly defined. According to a preferred embodiment of a soundproof cabin, adjacent wall modules form a visual gap of constant gap dimension extending along the preferably complete edge length. Alternatively or additionally, the outer side surfaces of the soundproof cabin can be formed directly by the optionally painted outer flat sides of the wall modules, in particular the cabin exterior hardboard. In this way, a simple check of the correctness of the assembly on sight is easily possible.

According to a preferred embodiment of a soundproof cabin, this has at least one first wall module, in which along at least one vertical or preferably upper (horizontal) edge side, an end face of the insulation board projects beyond at least one end face of at least one of the hard boards. Alternatively or additionally, the soundproof cabin comprises a second wall module, in which (for example, opposite the aforementioned edge side) at least one recess is formed between the opposing hard plates along a preferably lower edge side. The preferably vertical height of the board or the recess of the insulating board relative to the adjacent hardboard is greater than the thickness of the hardboard. Alternatively or additionally, the vertical height of the board of the insulating board of the first wall module and the vertical height of the recess of the second hard disk may correspond to each other.

It is clear that the "first wall module" or "second wall module" referred to in the individual claims is based on the respective relationship of the adjoining wall components and the designation as a "first" or "second" wall component only has a declaratory purpose , For example, in the case of two wall blocks adjacent in the vertical direction, the "first wall module" may be the lower wall module and the "second wall module" may be the upper wall module, or vice versa. For example, in the case of two wall modules adjacent to each other in a horizontal direction, the "first wall module" of the left wall module considered from inside the cabin and the "second wall module" may be the right wall module viewed from inside the cabin, or vice versa.

A preferred embodiment of a soundproof cabin comprises at least two, in particular horizontally adjacent to each other arranged wall blocks, the outer cabin hardboard plates preferably protrude in the horizontal direction respectively on the inside cabin hard plates. The insulation board of the first (left or right) wall module ends with the front side of the cabin outside hardboard and the insulation board of the second (other, right or left) wall module ends with the inside of the cabin hardboard. Alternatively, in such a soundproof cabin, the front sides of the insulating board te respectively step-like end between the end face of the cab outside hard plate and the front side of the cabin inside hardboard. Such a combination of wall blocks can be provided in particular for a corner wall segment, for example as described above in a soundproof cabin. A sound insulation cabin interior of the sound insulation cabin is determined in particular by a wall structure, ie spatially limited or defined. The wall structure is formed from mutually coupled, in particular fastened together, wall blocks. The wall blocks may have a multi-layer structure, such as a composite structure, with an integrated insulation layer or an integrated insulation material. The soundproof cabin can have at least one passage opening made in the wall structure. The passage opening can be formed as a bore or milling. A passage opening inside may also have a thread, but also a smooth through-hole inside without thread conceivable. It is clear that the passage opening at a passage opening entrance, ie flattened near a wall structure surface, can be beveled, for example in order to avoid sharp edges.

A arranged outside the wall structure, in particular electrically operated, supply air and / or exhaust air system is connected to the at least one passage opening air-conducting. This means that air, so the protective cabin surrounding air or air from outside the building by means of Zuluft- and / or exhaust air system via the at least one through hole in the soundproof cabin interior supplied or air, which will usually be used air from the Sound insulation cabin interior through the at least one through-hole can be derived by means of the supply air and / or exhaust system in the environment. Air-conducting is to be understood in such a way that a type of Luftzirkula- on or air promotion can take place. Preferably also air-conducting implies that the supply and / or exhaust air system is connected substantially airtight to the at least one passage opening. This has the advantage that the air exchange between sound enclosure inside and cabin environment, building environment or fresh air reservoir, depending on the use of Zuluft- and / or exhaust air system takes place substantially lossless. It is conceivable that the supply air and / or exhaust air system is designed exclusively as Zuluft- and thus ventilation system. As a result, substantially only air from outside the soundproofing cabin is guided into the soundproofing cabin interior via the passage opening, that is to say the ventilation opening, connected to the ventilation system. Alternatively, it is possible that the supply air and / or exhaust air system is used exclusively as a air system is configured so that essentially exclusively air from the soundproof cabin interior is conveyed outwardly into the soundproof cabin environment via the passage opening, ie exhaust port, connected to the exhaust air system.

As an alternative to the connection of the supply air and / or exhaust air system with the Schallschutzkabin environment or the building environment, the supply air and / or exhaust air system may also be connected to a fresh air reservoir to ensure use of the soundproof cabin in environments where insufficient or there is not enough clean air in the area and surroundings.

In an exemplary embodiment, the at least one passage opening extends transversely, in particular rectilinearly, preferably without steps, from a soundproof booth outside in the direction of the soundproof booth inside, or vice versa. The at least one passage opening can thereby extend completely through the wall structure. This means that the passage opening extends from a cabin-inside wall structure surface to a cabin exterior-side wall structure surface. An opening cross section of the passage opening may be formed, for example, round, oval or angular. In the case of a round opening cross-section, i. a circular cylindrical passage opening, may have a diameter in the range of 10 mm to 200 mm, preferably between 50 mm and 150 mm or in particular 70 mm, 80 mm or 90 mm. In an exemplary embodiment of the soundproof cabin, the at least one passage opening is provided in a ceiling panel of the wall structure. The ceiling plate may have an identical structure as the wall blocks described above. In particular, the ceiling panel can be constructed of a multi-layer structure with a rigid panel facing the soundproofing cabin interior, for example made of veneer wood, and an insulating panel, for example of wood fiber material, arranged above the rigid panel. Thus, the ceiling plate may have a composite structure. In an exemplary embodiment, the insulation board and the rigid plate of the ceiling plate have the same base area at least in one plane, preferably a horizontal plane. This means that the insulation board completely covers the rigid plate in order to ensure a multilayer structure over the entire base area of the rigid plate. This has the advantage that the positioning of the through hole in the ceiling plate can be realized at any point and is always identical.

In a further exemplary embodiment of the soundproofing cabin, the ceiling panel is integrated into the wall structure in such a way that it forms the one side wall of the soundproofing cabin. the wall blocks in sound insulation cabin height direction, ie in particular in the vertical direction, protrude beyond the ceiling plate. As already stated above, the wall structure defines the soundproof booth interior. It is clear that the side walls define or limit the soundproof cabin interior in a horizontal direction, and the ceiling panel determines or limits the soundproof booth interior in a vertical direction. In particular, the wall units in sound enclosure height direction are also above the ceiling plate arranged above, preferably on this resting, supply air and / or exhaust system out. This means that if the at least one passage opening is introduced into the ceiling plate, it is advantageous if the supply air and / or exhaust system is placed on the ceiling plate in order to achieve a compact design. Furthermore, this also ensures a structurally simple design of the noise control cabin, since no additional holding or stowage units must be mounted on the building interior floor or on one of the side wall modules. The ceiling plate is preferably integrated into the wall structure in such a way that the wall blocks forming a side wall protrude beyond the ceiling plate so far in the sound enclosure height direction, ie in the vertical direction, that they also project in the vertical direction via the supply air and / or exhaust air system. This beautifies the visual impression of the soundproof cabin, as persons in the vicinity of the cabin do not see the components of the supply air and / or exhaust air system. In addition, the supply air and / or exhaust system is thus protected against unwanted access from the outside by unauthorized persons.

The ceiling plate may additionally comprise an insulation plate, for example made of plastic, for electrically insulating the sound insulation booth wall structure, which is arranged in particular above the insulation board. Alternatively, the insulation board can also be made of electrically insulating material and thus realize both a sound insulation and electrical insulation. In an exemplary embodiment, the insulation plate, the insulation board and / or the rigid plate of the ceiling plate have the same base area at least in one plane, preferably a horizontal plane. This means that the insulation plate completely covers the insulation board and / or the rigid plate in order to ensure electrical insulation over the entire base area of the insulation board and / or the rigid plate.

In the exemplary embodiment, the supply air and / or exhaust air system comprises a pump, such as a suction or pressure pump, and arranged in the air conveying direction upstream of the pump air filter for filtering out, for example, dust particles from the ambient air.

Corresponding components of individual wall modules have the same reference numerals increased by 10 in the following for easy readability.

A wall element according to the invention, for example wall element 2, is essentially composed of a hardboard 21 on the inside of the cabin, a hardboard 23 on the outside of the cab and an insulating layer arranged between the opposing hard plates 21, 23, for example in the form of an insulating board 25. The insulation board 25 is a preferably pressed wood fiber board with a thickness in the transverse direction Q of about 40 mm.

The cabin-inside hard plate 21 and the cab outside hard plate 23 may preferably both be configured as a veneer panel. It is conceivable that, in particular, the cabin-inside hard plate 21 is covered on its cabin-side flat side with a further sound insulation material, for example a fleece or felt mat. It is also conceivable that the cabin interior hard plate 21 is partially removed in the transverse direction and replaced by an additional insulating layer, for example, the aforementioned nonwoven or felt mat. For this purpose, for example, a recess may be formed in or through the cabin-inside wall plate 21.

The cabin outer side hard plate 23 may preferably be formed by a plywood board, in particular with a thickness of about 19 mm in the transverse direction. Preferably, the cabin outer-side wall plate in the vertical direction V and / or horizontal direction H extends at least as far as the associated inside cabin hardboard 21 of the same wall module 2. It is conceivable that the cabin outer side hard plate 23 in the vertical direction V is greater and below and / or above the cabin inside wall plate 21 protrudes. It is conceivable that the cabin outer side wall plate 23 ends in the horizontal direction at least at one (right or left side view of the cabin inside) side in alignment with the cabin inside wall plate 21 or protrudes beyond.

In the wall module 2 of Fig. 1, the upper horizontal end face of the two hard plates 21, 23 are arranged in alignment with each other in the vertical direction. In the vertical upper horizontal front edges are recesses for anchors for fixing a vertical kalrichtung V arranged above second, upper wall module 1 is provided. The insulation board 25 of the wall module 2 terminates in the vertical direction V below the plane defined by the upper edges of the hard plate 21, 23 surface. In the recesses formed in this way between the hard plates 21, 23 in the transverse direction in the vertical direction V down over the recess 26 on the lower edge side or front side surface of the hard plates 11, 13 of the upper wall module 1 protruding insulation board 15 can be inserted.

The two wall blocks 1, 2 are preferably matched to one another, with a surface contact touch along the horizontal end faces of the hard plates 21, 23 and 11, 13, the recess 26 at the upper end or the horizontal edge side of the wall block 2 by the board 16 of the insulation board 15th of the upper wall module 1 is completely executed. The insulation panels 25, 15 have a rectangular cross section and form corresponding rectangular Berührkontaktflächen with each other. It remains between the wall modules 1 and 2 connected after completion of assembly (not shown) no clearance between the insulation boards 15 and 25th

The upper end faces of the hard plates 21, 23 (on the upper horizontal edge side of the wall block 2) and the lower end faces of the upper hard plates 11, 13 (on the lower horizontal edge side of the wall block 1) extend in the horizontal direction and each have a rectangular cross section, wherein the end faces of the kabinenaußenseiti- wall plates 13 and 23 are the same size. The end faces of the cabin-inside wall panels 21 and 11 are all over in contact contact also designed with the same cross-section.

FIG. 2 shows two wall elements 2 and 3 which are adjacent in the horizontal direction and which can be assembled to form the corner wall segment 200 depicted in FIG. 3. For the assembly, the hard plates 21, 23 with their vertical lateral end faces (on the vertical edge side of the wall module 2) must be pushed against an inside flat side of the hard plates 31 or 33 (on the vertical edge side of the wall module 3) of the adjacent wall module 3. Along the lateral end face 22 of the inner hard plate 21 or the lateral end face 25 of the outer with the flat side of the hard plates 31, 33 of the wall component 3 adjacent to the corner formed. The wall panels 21, the cabin-inside wall panels 21 and 31 are preferably the same thickness in their respective transverse direction. The abutting cabin outer side hard plates 23 and 33 are preferably the same thickness in their respective transverse direction. The transverse direction of the wall module 2 is connected to the Reference character Q ₂ provided and the transverse direction of the wall block 3 is denoted by the reference Q ₃ .

In the contact region, the wall blocks 2 and 3 abut each other substantially at right angles. In this case, a rectangular corner region is formed between the inside flat sides of the cabin-inside hard plates 21 and 31. The outer flat side of the cab outside hard plate 23 is aligned with the end face of the cab outside hard plate 33. The vertical and horizontal end faces of the individual hard plates are at right angles relative to each other. The flat sides of the individual wall panels are also at right angles relative to their end faces.

The insulation boards 25 and 35 are on the respective cabin inside hard plate 21 and 31 in the respective horizontal direction so far forward that the insulation board 25 abuts the end face on the insulation board 35, so that in the corner region of the wall segment 200, the insulation boards 25 and 35 free of space, more precisely said cavity-free, meet. Between the insulation boards 25 and 35, a full-surface contact is formed along the front side of the insulation board 25.

The space between the cabin interior side wall panels 21, 31 and the cabin outer side wall panels 23, 33 is completely filled by the insulation panels 25 and 35. Das Dämmplatte 35 abuts the end face against the inside of the cabin outside hardboard 23 of the other wall module. The insulation board 35 extends over the entire transverse width of the insulation board 25 of the other wall module 2, so that there is a 100% overlap. The end face 37 of the insulation board 35 is in touching contact with the outer hard plate 23 of the other wall module 2. The insulation board 25 is in the horizontal direction on the front side 22 of its cabin inside wall plate 21, so that the end face 27 of the insulation board 25 with the inside of the insulation board 35 in is a touch contact.

In Fig. 2 it can be seen that on the inside or flat side of the cabin inside wall plate 31, a contact area 32 is defined by the area where the horizontal end face 22 of the cabin inside wall plate 21 abuts against the inside cabin hard plate 31 of the other wall module 3. Similarly, in the inner side of the cabin outer side wall plate 33 of the wall module 3, a contact surface 34 is defined by the area in which the horizontal end face 24 of the cab outside hard plate 23 of the wall module 2 abuts against it.

In the contact areas fastening means are provided, which are shown in Fig. 2 by way of example by male connectors 83 of the wall module 2 and female connector components 84 on the inner sides or flat sides of the wall module 3. The fasteners may be, for example, Owotech connectors. The extension of the connectors in the transverse direction of the module, on the front side of which it is provided, is smaller than the respective width of the hard plates 21 and 23 into which they are inserted. The connectors allow a simple insertion and / or insertion connection of the two wall blocks 2 and 3 with each other. For example, the sleeve-like male fastener component 83 can first be inserted horizontally into respective connection components 84 and then locked and / or secured to each other by translational relative movement of the wall blocks 2 and 3.

Preferably, the cabin inside hardboard, the insulation boards and the cabin exterior hard or wall panels of wall elements described above each form a composite structure in which the respective insulation board with the associated hard plates by an adhesive, such as an adhesive, or a resin, such as a synthetic resin , a glue or the like, are connected to each other. It is possible to provide further composite layers between the three illustrated layers: cabin interior hardboard, cabin exterior hardboard and insulation board.

For the precise alignment of the hard plates and the insulating board, as shown by way of example in FIGS. 4 a, 4 b and 4 c, the use of internal recesses, ie hardboard recesses 18 and / or insulating board recesses 19 and pins 88 corresponding in shape to the respective recesses 18 and 19, respectively be provided. A pin 88 may, for example, be designed as a solid material body in the manner of a pin, wherein the same or another, for example, smaller, outer diameter may be provided for the application area in the Dämmplattenaussparung 19, as for the Hartplattenausneh- tion 18 usable portion of the pin 88. The cross section of the pin 88 is preferably circular. Other cross-sectional shapes, for example elliptical, triangular, rectangular, in particular square, cross-shaped or star-shaped, are also conceivable. The pin 88 may, in the manner of a pipe end piece, be provided by a hollow cylinder section, which is preferably provided on the outside with a barb structure and is inserted into the insulation boards. 19 can be used, and a disk or plate-like portion preferably be designed for insertion into the hard disk recess 18.

The pin 88 is inserted in the transverse direction in a recess of the insulation board 19 and / or in a recess 18 of the hard plate 13 and connected both to the hard plate 13 and the insulation board 15. As a result, the pin 88 ensures a positive connection in a predetermined relative position between the hard plate 13 and the insulation board 15. If a non-round cross-section pin 88 (not shown) is used, a single pin 88 may already be sufficient for a clear definition of the relative position of the insulating board 15 relative to the hard board 13. In the case of a journal 88 with a circular cylindrical cross-section, it is preferred to use a plurality, that is to say at least two, pins 88 for defining a relative position of the insulating panel 15 relative to the hardboard 13. After insertion of the pin 88 in the recess (18 or 19) of the hard plate 13 or insulation board 15, the pin realized in the horizontal direction H and in the vertical direction V a positive connection between the insulation board 15 and the hard disk 13. For fastening the insulation board 15 and the hard plate 13 can be provided preferably the large-area application of an adhesive layer (for example, on a glue, paste, resin or adhesive layer). Preferably, the insulating layer 15 is connected by the adhesive directly to the hard disk 13. With regard to FIG. 4, the connection of the insulation board 15 with the outside hard plate 13 is shown, it being understood that a corresponding form-fitting connection between the insulation board 15 and the interior cabin hardboard 11 (not shown) can be provided.

If both the outside of the cabin and the inside of the cabin are provided in the insulating board 15 for fastening a respective hard plate 13 or 11 pins 88 or the like, it may be preferable to arrange the inside pins 88 in the transverse direction, vertical direction and / or horizontal direction offset relative to the outside pins to ensure that an uninsulated sound transmission from one hard disk to another via a bridge in the form of one or more of the insulating plate 15 penetrating pin is avoided.

In order to avoid that the relatively soft insulating board made of a pressed wood fiber material moves locally, wedges or the like in comparison to the hard plates, which are formed for example of veneer wood, it may be preferred that distributed over the surface of the insulating board 15 a plurality of pins 88 are provided for fastening the insulation board 15 to an associated hard plate 13. FIG. 7 shows a solid pin 88a without an internal cavity and a sleeve-shaped pin 88b with a cylindrical internal cavity 95. The pins 88a, 88b are rotationally symmetrical. In the direction of their respective axes of rotation, the pins 88a, 88b have a barb portion 91 and a lid portion 93. The outer diameter of the barb portion 91 is smaller than that of the lid portion 93. The axial length of the barb portion 91 is greater than the axial length of the lid Section 93. As indicated in Figure 4b, a pin 88 can be used with its barb portion 91 in a form complementary or dimensioned for a compression of the pin insulation board recess 19. The cover section 93 can be inserted into a form-complementary hard-plate recess 19.

For example, an insulation panel 15 shown in FIG. 4b may have a thickness in the transverse direction of approximately 4 cm. The thickness of the hard plates 11, 13 may be about 19 mm. The height of the lid portion 93 is smaller than the thickness of the hard plates 11, 13, preferably smaller than half the thickness of the hard plates 11, 13, and may be, for example, 2 mm to 5 mm in size. The height of the barb portion 91 is smaller than the thickness of the insulating panel 15, preferably smaller than half the thickness of the insulating panel 15, and may be, for example, 5mm to 20mm or 30mm in size. The height of the barb portion 91 is preferably greater than the height of the lid portion 93. It is clear that the designated here as barb portion 91 part of the pin 88, which is provided for insertion into the insulating mat, alternatively designed to be free of barbs and in so far as insulation board insertion section could be designated. It should be understood that the lid portion 93, shown here as a substantially flat, circular and disc-like plate, may optionally be provided with a different shape, and in particular with barbs. The cover section 93 can also be referred to as a hard-plate insertion section. The cylindrical pins shown in Figures 4b and 7 have a base area of about 5 cm ² to 10 cm ² and a lateral circumference with a width of 5 cm to about 10 cm.

The projecting portion 16 of the insulation board 15 projects into the respective Innenausneh- mung 26, 36, 46, 56, 66 of the lower wall blocks 2, 3, 4, 5 and 6 for installation with the sound insulation cabin and fills them completely. The Eckwandsegmente are designed as described above and realized by a jerky connection between an end face such as a plate and a contact area on an inner side of the respective neighboring plate.

In Fig. 6, a sound enclosure interior 103 of the sound enclosure 100 is defined by a wall structure 105, i. spatially limited or defined. The wall structure 105 is formed from wall elements 109 which are coupled to one another and in particular fastened to one another. The wall modules 109 may have a multi-layer structure, such as a composite structure, with an integrated insulating layer or an integrated insulating material.

Further, located at a top position of the noise control cabin, a portion 129 of a wall block 109, which projects beyond a sound insulation booth interior 103 in the vertical direction limiting ceiling plate 125 (not shown). On a lower side of the soundproof cabin 100, this has a bottom plate 107 for parking the soundproofing cabin 100 on the floor. In the embodiment according to FIG. 1, the wall components 109 of the wall structure 105, the ceiling plate 125 and the bottom plate 107 are arranged with respect to one another in such a way that they define a soundproof cabin interior 103 of rectangular cross-section. Other cross sections of the cabin interior 103 are also intended to be covered by the present invention.

The soundproof cabin 100 also has a door 113 with a handle 121 for entering the soundproofing cabin 100 or for exiting the soundproofing cabin 100. The door 113 is hingedly connected to the wall structure 105 via at least one hinge 117, in particular two hinges 117 according to FIG. 6. The door 113 is intended to close the soundproofing cabin 100 in such a way that it is largely prevented that sound in the closed state of the soundproofing booth 100 can leave it via the door 113 or via an interface area 115 between the door 113 and the wall structure 105. The features disclosed in the specification, the figures and the claims may be of importance both individually and in any combination for the realization of the invention in the various embodiments.
