Description

SOUND INSULATION CABIN

The invention relates to a soundproof cabin for freestanding construction in the building interior, such as a large office, a workshop, a hall or the like. A soundproof cabin can be used for example as a recording studio cabin, meeting room, acoustic room or telephone booth.

A generic freestanding sound enclosure is suitable for use within a building structure, such as within a large office to provide a room in the room, which is acoustically separated from the rest of the room, so that talks, such as meetings or phone calls, undisturbed within the sound insulation by the in 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, can be provided between a soundproofing 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.

Known sound-damping cells, as described for example in EP 2 481 868 Bi, basically consist of a base plate, a frame or a wall-forming wall plates and a soundproofing cell upwards final ceiling plate. The plate elements are in such a precise fit and interconnected using additional sound insulation materials that an effective insulation between Schalldämpfungszelleninnenraum and the environment is achieved. However, a disadvantage of such sound-damping cells is that they provide no or sufficient cell interior ventilation, so that an air circulation or an air exchange is possible with the environment only by opening an integrated into the side wall entrance door of the cell.

From DE 102 14 778 Ai a sound-absorbing panel is known, which is used in walls of meeting rooms or so-called acoustic rooms for the production of music recordings. As a result of the sound absorption, the panel has at least partially penetrating perforations, such as slots or bores, which have a diameter of 1 mm or 2 mm. According to DE 102 14 778 Ai improve the perforations, although only the sound absorption and thus the sound insulation, but ensure the perforations at least a certain passive ventilation of the interior, as in particular spent air through the perforations or holes from the interior into the environment and fresh or Ambient air can enter the interior from the outside. On the one hand, such a ventilation system has the disadvantage that only a very slight air circulation takes place. Furthermore, the integrated in the panel sound insulation material has the disadvantage that it can accumulate germs of any kind and any dust particles, so that the panels must be replaced in a certain rhythm, especially to be suitable for people with a dust allergy.

It is therefore an object of the present invention to improve the disadvantages of the prior art, in particular to provide a soundproofing cabin for building interiors, which ensures efficient, quiet and hygienic ventilation of the soundproofing cabin.

This object is solved by the features of claim 1. Exemplary embodiments are given by the subclaims.

According to the invention, a soundproof cabin is freestanding in a building interior, such as a large office, a workshop or the like, built or set up. Such a soundproof cabin can be, for example, a telephone booth, an acoustic booth, a meeting room or any other cabin or cell spatially separate from the building interior.

A sound insulation cabin interior of the sound insulation cabin is defined 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 composite structure of the wall module comprises a cabin-side hard plate and one of these opposite cab outside hard plate and the arranged between the inside of the cabin hard drive and the outside of the cabin hard drive plate Insulating layer, preferably made of 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. According to an exemplary embodiment, the insulating layer comprises a fiber material insulation board, in particular a Holzfaserdämmplatte. 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 effect 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 an exemplary embodiment of a wall module, 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. In a preferred embodiment of a wall module, 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 an insulating layer of pressed fiber material, has proven to be particularly suitable with regard to the combination of mechanical stability and acoustic insulation effect. The composite structure may include a direct adhesive bond, such as an adhesive bond, such as a resin or glue compound, between the insulating layer and at least one cabin interior and / or cabin exterior hardboard. By preferably large-area adhesion of the insulating layer to one or both hard plates, the 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.

A wall segment, in particular a corner wall segment, may comprise two wall blocks. The wall modules can be designed in particular as described above. The wall blocks comprise two oppositely arranged hard plates, in particular plywood panels, and arranged between the two hard plates insulation board. The two wall modules are arranged in such a way that at least one hard plate of the first wall module with a hard plate of the second wall module a Contact area defined. 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-outside 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 member may include a barb component on the first wall brick and a complementary retaining component with recesses for fixing the barb component in the second brick brick. Preferably, the attachment member may be an 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 successive hard plates allows a simple, yet stable and precise installation of wall segments or soundproof cabins of 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 insulation board (s), so that the sound-absorbing effect of the insulation boards is not affected by the at least one fastening part.

According to an exemplary embodiment of a wall segment, the wall blocks are connected to each other in abutment such that the end face of the first wall block is perpendicular to a flat side of the second wall module and that the outer flat side of the first wall module is aligned with the end face of the outside of the cabin hardboard of the second wall module. 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 exemplary embodiment of a wall segment, the wall blocks are connected to each other in abutment such that the end faces of the wall blocks are in pairs to each other 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 exterior of the sound enclosure. The inner flat sides of the wall blocks form a composite flat inside of the soundproof cabin. Such a wall segment can be provided, for example, in a soundproof cabin provided as a meeting room along a relatively long side wall, so that it is avoided that a single wall unit must extend over the entire width of the soundproof cabin.

According to an exemplary 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 blocks on the cabin outside and / or the cabin inner side face are free of connecting means, such as fastening parts. In particular, no belts, angle plates or other fittings provided for connecting two wall modules are arranged on the outside of the wall modules or of the wall segment or soundproof cabin. Preferably, no connecting means or fastening parts are provided in the region of the insulation boards.

According to an exemplary 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 soundproof cabin, which can be designed as described above and is designed for a sound insulation of at least 30 dB between the cabin interior and the environment, several wall blocks as described above with an inner flat side, an outer flat side, two horizontal edge sides and two vertical edge sides, and optionally at least one wall segment as described above include. The plurality of wall blocks are mounted on each other along their edge sides to each other, that the insulation boards of two adjacent wall blocks are in contact with each other in a flat contact. 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 an example that the wall modules free of gaps, 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 surface touch contact between the insulation boards of adjacent wall blocks or a gap-free adjacent arrangement of two adjacent wall blocks a sound-permeable cavity is avoided and clearly defined the mounting orientation.

According to an exemplary 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 an exemplary embodiment of a soundproof cabin, the latter has at least one first wall component, in which at least one vertical or preferably upper, (horizontal) edge side projects an end face of the insulation panel over at least one end face of at least one of the hard panels. 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 plate relative to the adjacent hard plate is greater than the thickness of the hard plate. 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.

An exemplary embodiment of a soundproof cabin comprises at least two, in particular horizontally adjacent to each other arranged wall blocks, the outer cabin hard-side plates preferably protrude in the horizontal direction in each case 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 end faces of the insulation board in each case end in a step-like manner between the end face of the outside of the cabin outside the cabin and the front side of the inside of the cabin 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.

The soundproof cabin can have a door with a handle for entering the soundproofing cabin or for exiting the soundproofing cabin. For example, the door may be hinged to the wall structure via a hinge, preferably via two hinges. In an exemplary embodiment, the door is made largely of glass, or has at least one glass window. Furthermore, the sound enclosure may be a separate, i. have soundproof cabin interior lighting separate from the building interior.

The soundproofing cabin furthermore has at least one passage opening introduced into 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 through-hole entrance, i. flattened near a wall structure surface, as beveled, may be, for example, to avoid sharp edges.

A arranged outside the wall structure, in particular electrically operated, with other control options are conceivable 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 supplied via the at least one through-hole in the sound enclosure interior or air, which usually be used air is, can be derived from the sound insulation cabin interior through the at least one through hole by means of the supply air and / or exhaust system into the environment. Air-conducting is to be understood in such a way that a kind of air circulation 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 designed exclusively as an exhaust air system, so that via the connected to the exhaust system through-hole, so exhaust port, substantially only air from the noise insulation cabin interior is transported to the outside in the sound enclosure environment.

As an alternative to the connection of the supply air and / or exhaust air system with the sound enclosure 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 sound enclosure in environments where insufficient or not sufficient pure air is present in the area.

In an exemplary embodiment, the at least one passage opening extends transversely, in particular rectilinearly, preferably without steps, from a soundproofing cabin outside in the direction of the soundproofing cabin 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. However, it is also possible that the at least one through opening does not extend completely, but only partially, for example to 50%, 60%, 70%, 80%, 90% or 95%, through the wall structure. In particular, the passage opening extends completely through, for example, an insulating layer integrated in the wall structure multilayer over the wall structure. 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, ie a circular cylindrical Through hole, 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, an adapter, such as a sleeve or insert, be inserted into the through hole to facilitate the connection of the supply air and / or exhaust system, as by means of the adapter manufacturing inaccuracies in terms of the passage opening can be compensated. In particular, the adapter is dimensioned such that it is tuned on the one hand to the Durchgangsöffnungsdurchmesser and Durchgangsöffnungsform and on the other hand on the supply air and / or exhaust system. A length of the adapter measured in an extension direction of the passage opening can be dimensioned such that the adapter is recessed flush in the passage opening. This means that the adapter in the direction of extension of the passage opening does not protrude beyond the wall structure surface. Alternatively, the adapter may have at one axial end, as measured in the direction of extent of the passage opening, a mounting flange for axially defining a mounting end position, which rests in the Montageendposition on the wall structure surface.

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 of a multi-layer structure with a sound insulation cabin interior facing rigid plate, such as plywood, and arranged above the rigid plate insulation board, for example, made of wood fiber material, be constructed. 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 soundproof cabin, the ceiling panel is integrated into the wall structure in such a way that the wall units forming a side wall of the soundproof booth protrude above the ceiling panel in the sound enclosure height direction, ie in particular in the vertical direction. As already stated above, the wall structure defines the soundproof booth interior. It is clear that the side walls define or limit the soundproof booth interior in a horizontal direction and the ceiling panel defines the sound enclosure 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. Preferably, the ceiling plate is integrated in such a way in the wall structure, that the side wall forming wall blocks so far in sound enclosure height direction, ie in the vertical direction, protrude over the ceiling plate, that they also protrude through the supply air and / or exhaust system in the vertical direction. This beautifies the visual impression of the soundproof cabin, as persons in the vicinity of the cabin can not see the supply air and / or exhaust air system. In addition, the supply air and / or exhaust air 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 an exemplary embodiment, the supply air and / or exhaust air system may include a heat recovery unit, such as a heat exchanger, in particular plate heat exchanger, preferably with electrical Nachregister, and / or cooling unit, such as a refrigerator. The supply air and / or exhaust air system can replace in particular consumed air in the noise insulation cabin interior by fresh air from the outside. The heat contained in the exhaust air can be stored in a heat exchanger and transferred to the supply air. A large part of the heat energy of the exhaust air can thereby be recovered, in particular, an efficiency of over 90%, preferably up to 98%, should be strived for. In the present supply air and / or exhaust air system of the soundproof cabin, a recuperative heat recovery with Separate streams, regenerative heat recovery with heat storage medium or heat recovery can be used with heat pumps. An example of a recuperative heat recovery unit is a plate heat exchanger in which the supply air flow and the exhaust air flow do not come into contact with each other, but at least one serving for heat transfer plate disposed between the air streams. In regenerative heat recovery units, the thermal energy is not transmitted directly, but indirectly from one to the other air flow. In the supply air and / or exhaust air system, supply and supply air are alternately passed through a storage medium. This absorbs the energy of one airflow and transfers it to the second airflow. An example is a rotary heat exchanger. Another option for heat recovery is provided by a heat pump, which can extract thermal energy from the exhaust air. A refrigeration unit, such as a refrigeration machine or an air conditioner, serves to bring and maintain the air inside the soundproof cabin interior in a specific state. For example, the interior temperature and the indoor humidity can be set and monitored. It is clear that such a heat recovery / cooling unit must be adapted to the size, ie the volume, of the soundproof cabin interior.

In the case of an electrically operated supply air and / or exhaust air system, an electrical power supply may be provided. For this purpose, the wall structure, in particular on a wall module, on the inside of the cabin and / or on the outside of the cabin wall structure have an opening for the cable connection. Preferably, the opening is mounted outside the cab and a channel-like cable guide integrated into the wall structure towards the supply air and / or exhaust system. In an exemplary embodiment, an electrical switch for activating and / or deactivating the supply air and / or exhaust air system is attached to a wall structure inside and / or wall structure outside. This means that an opening for inserting the switch must be provided on the cabin interior and / or cabin exterior wall structure surface. Preferably, the switch is disposed inside the cab, the connection being to the power supply via an outside cabin opening in the wall structure surface for passing connection cables, which is preferably positioned in alignment with the switch opening. Preferably, the switch opening is located at a common, ergonomic vertical height, for example, 1.5 m above the floor, and the cable connection opening on the outside of the cabin at a much lower vertical height, especially near the ground, to increase the visual impression of the cabin. It is clear that the connection cables must be routed from the cable connection opening to the switch opening. This can be achieved for example by a channel which is introduced into the wall structure, or in that already during assembly of a Wall blocks, for example, be laid between insulating layer and a hard drive connection cable. The switch ensures that the supply air and / or exhaust air system is only switched on when needed and otherwise switched off in order to save energy. Alternatively or additionally, a preferably wireless user interface, such as an input terminal or a remote control, may be provided for setting sound enclosure parameters, such as temperature or aeration level. In the case of a wireless remote control, it is clear that a corresponding receiver, a processing unit and an output unit for processing the input commands of the user can be integrated into the supply air and / or exhaust air system. The user interface, or the input terminal, may also be attached to a wall structure inside and / or wall structure outside.

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. Exemplary pump blower powers are in the range of 100 ms / h to 1000 m ³ / h, preferably in the range of 250 m ³ / h to 750 m ³ / h. For reasons of use, low-noise fresh air and / or exhaust air systems, in particular low-noise pumps, are preferred. In this case, sound pressure levels below 70 dB, preferably below 60 dB, preferably below 50 dB, preferably below 40 dB, preferably below 30 dB, in particular below 20 dB have proven particularly advantageous. The supply air and / or exhaust air system may further comprise a noise sensor for measuring the volume of the system, in particular the pump. The sensor can measure and monitor the sound pressure level during operation of the supply air and / or exhaust air system and output a message based on the measurement data if, for example, the noise level is above a predetermined maximum sound pressure level for a period of 5 minutes. Based on this, an exchange of the plant or the pump can be initiated. By means of the air filter, which is for example a filtering medium and can remove substances from the air, unwanted particles are kept away from the soundproof cabin interior, in particular in order to be suitable for people with, for example, a dust allergy.

In a preferred embodiment, a particularly flexible ventilation hose connects the supply air and / or exhaust air system with the passage opening. This means that a ventilation hose is used to connect the supply air and / or exhaust air system to the passage opening. The material of the ventilation hose may for example be plastic, in particular polyvinyl chloride (PVC), cardboard or aluminum. An outer diameter of the ventilation hose may preferably be 80 mm, although other outer diameters are also conceivable. At one axial end of the ventilation hose, measured in the air conveying direction, this has a preferably rigid mounting portion which is complementary in shape to the passage opening to connect the ventilation hose by means of the mounting portion in the passage opening. When an above-described adapter is inserted into the through hole, the mounting portion is shaped to complement the adapter to connect the ventilation hose in the adapter. The mounting portion may have a slight radial excess, preferably of a few millimeters, in particular of 1 mm, relative to an inner diameter of the passage opening, or relative to an inner diameter of the adapter, as far as possible in order to avoid unwanted axial relative movement between the ventilation hose and the passage opening or the adapter to avoid.

For example, the vent hose is substantially circular cylindrical, i. with a circular cross-section, formed, wherein further cross-sectional shapes are conceivable depending on the shape of the passage opening. At an axial end of the mounting portion, it has one in the radial direction of the ventilation hose, i. perpendicular to the axial direction of the ventilation hose, via a mounting portion outer diameter protruding mounting projection for defining an axial mounting end position of the ventilation hose in the through hole, or in the adapter on. When mounting the ventilation hose in the through hole, or in the adapter, the mounting projection serves as a stop and is in the final assembly position on the wall structure surface. The mounting projection may be formed as a preferably closed annular flange whose outer diameter is greater than the passage opening inner diameter.

Furthermore, a silencer, such as a telephony silencer or a pipe silencer, may be provided, which connects the supply air and / or exhaust air system and the ventilation hose with each other. Alternatively, the ventilation hose can also be omitted and the muffler can be connected both directly to the supply air and / or exhaust system and the passage opening. A silencer may be constructed, for example, of a cylindrical outer housing, in particular of sheet steel, a cylindrical inner housing, in particular of sheet steel, and a filling provided between the inner housing and the outer housing, preferably of mineral wool, for sound insulation. The muffler may have a length in the range of 200 mm to 1500 mm, an outer casing diameter in the range of 100 to 500 mm, and an inner casing diameter in the range of 50 to 300 mm. At the axial ends of the muffler can be mounted in each case a connecting sleeve for connection to the supply air and / or exhaust air system or to the ventilation hose or the passage opening. It is clear that the respective connecting sleeve thereby on the corresponding connection part formabgestimmt, in particular form-complementary thereto is formed.

In an exemplary embodiment of the soundproofing cabin, at least one further passage opening is introduced into the wall structure and designed for connecting a second ventilation hose. Preferably, the at least one further passage opening is identical to the above-described at least one passage opening. In particular, the second ventilation hose is also identical to the first ventilation hose already described. This means that the preferably flexible second ventilation hose can comprise an in particular rigid mounting section, which is configured complementary to the shape of the at least one further through-opening. Furthermore, the mounting portion may have a slight radial excess, preferably of a few millimeters, in particular of 1 mm, relative to an inner diameter of the at least one further through opening. At a mounting portion axial end, a mounting projection projecting radially beyond a mounting portion outer diameter may axially restrain the second vent hose in the at least one further through hole. The mounting projection may be formed as a preferably closed annular flange whose outer diameter is greater than the inner diameter of the at least one further through opening. In a further development, the second ventilation hose connects the at least one further through-opening with a second silencer, which is in particular identical to the first silencer already described.

The second muffler may have at a first axial end a first connection sleeve for connection to the second ventilation tube provided in the at least one further passage opening and at a second axial end a second connection sleeve for connection to a third, in particular identically designed, ventilation tube. Preferably, no supply air and / or exhaust air system is connected along the air conveying path through the at least one further passage opening. However, it is also possible that a further supply air and / or exhaust air system is connected in an air-conducting manner to the at least one further passage opening. In order to ensure effective air circulation between the sound insulation cabin interior and environment, the at least one further passage opening superficially serves as ventilation or exhaust air line when the supply air and / or exhaust air system is at least superficially set up to supply the cabin interior with fresh air. Preferably, in one embodiment with two supply air and / or exhaust air systems, the one exclusively designed as a supply air system and the other exclusively as an exhaust system, so get over the one passage only air into the sound enclosure inside and on the at least a further passage opening only air can pass out of the cabin interior to the outside.

A cover or cover plate with in particular identical base as the ceiling plate can be arranged above this and flush over the ceiling plate, and in particular on the supply air and / or exhaust system, protruding wall blocks flush. In this case, the cover acts as a kind of cover for a space formed by the ceiling plate and the sides of the ceiling plate and about this protruding wall blocks space in which the supply air and / or exhaust system is located. In an exemplary embodiment, all components connected to the supply air and / or exhaust air system, such as ventilation hoses, silencers and connecting sleeves, are located in the space bounded by the cover panel, the ceiling panel and the wall modules. On the one hand, this enhances the visual impression also from above on the soundproof cabin, since the functional components belonging to the supply and / or exhaust air system are not visible, and on the other hand, the cover panel protects the components concealed by it from dust or other external influences.

In the embodiment according to FIG. 1, the wall blocks 9 of the wall structure 5, the ceiling plate 25 and the base plate 7 are arranged with respect to one another in such a way that they define a soundproof cabin interior 3 of rectangular cross-section. Other cross sections of the sound enclosure interior 3 are also intended to be covered by the present invention. The soundproof cabin 1 also has a door 13 with a handle 21 for entry into the soundproofing cubicle 1 or for exit from the soundproofing cubicle 1. The door 13 is hingedly connected to the wall structure 5 via at least one hinge 17, in particular two hinges 17 according to FIG. 1. The door 13 should be there in such a way soundproof the soundproof cabin 1 conclude that is largely prevented that sound in the closed state of the soundproof cabin 1 can leave this through the door 13 and via an interface region 15 between the door 13 and wall structure 5.

A wall module according to FIG. 2, for example the wall module 1002, is essentially composed of a hardboard 1021 on the inside of the cabin, a hardboard 1023 on the outside of the cabin and an insulating layer arranged between the opposing hardboards 1021, 1023, for example in the form of an insulating panel 1025. The insulating board 1025 is a preferably pressed wood fiber board with a thickness in the transverse direction Q of about 40 mm.

The cabin interior hardboard 1021 and the cabin exterior hardboard 1023 may be both configured as a plywood board. It is conceivable that, in particular, the cabin interior hardboard 1021 is covered on its inside cabin side flat side with a further sound insulation material, such as a nonwoven or felt mat. It is also conceivable that the cabin inside hardboard 1021 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 interior wall panel 1021.

The cabin exterior hardboard 1023 may preferably be formed by a plywood panel, in particular having a thickness of about 19 mm in the transverse direction. Preferably, the cabin outer-side wall plate extends in the vertical direction V and / or horizontal direction H at least as far as the associated inside cabin hardboard 1021 of the same wall module 1002. It is conceivable that the cab outside hard plate 1023 in the vertical direction V is greater and below and / or above protrudes the cabin inside wall plate 1021. It is conceivable that the cabin-side wall panel 1023 ends in the horizontal direction at least at one side (right or left side view of the cabin inside) in alignment with the cabin interior side wall panel 1021 or beyond.

In the wall module 1002 of FIG. 2, the upper horizontal end side of the two hard plates 1021, 1023 are arranged in alignment with each other in the vertical direction. Recesses for dowels for fixing a vertical direction V above the second, upper wall plate 1 are provided in the upper horizontal horizontal end edges in the vertical direction. The insulating board 1025 of the wall panel 1002 terminates in the vertical direction V below the plane defined by the upper edges of the hardboard 1021, 23 surface. In the thus formed in the transverse direction between the hard plates 1021, 1023 recesses in the vertical direction V down over the lower end face of the hard plates 1011, 1013 of the upper wall brick 1001 protruding insulation board 1015 are inserted.

The two wall panels 1001, 1002 are preferably matched to one another, in the case of a surface contact contact along the horizontal end faces of the hard plates 1021, 1023 and 1011, 1013, the recess 1026 at the upper end or the horizontal edge side of the wall plate 1002 by the projecting distance 1016 of the insulation board 1015 of the upper wall block 1001 is completed. The insulation boards 1025, 1015 have a rectangular cross-section and form corresponding rectangular Berührkontaktflächen with each other. It remains between the interconnected wall panels 1001 and 1002 after completion of assembly (not shown) no clearance between the insulation boards 1015 and 1025th

The upper end faces of the hard plates 1021, 1023 (on the upper horizontal edge side of the wall block 1002) and the lower end faces of the upper hard plates 1011, 1013 (on the lower horizontal edge side of the wall block 1001) extend horizontally and each have a rectangular cross section the end surfaces of the cabin outer side wall panels 1013 and 1023 are the same size. The end faces of the cabin inside wall plates 21 and 11 are all over the surface in contact also designed with the same cross section.

Fig. 3 shows two horizontally adjacent wall panels 1002 and 1003, which are composable to form a corner wall segment. For the assembly, the hard plates 1021, 1023 with their vertical lateral end faces (on the vertical edge side of the wall module 1002) must be pushed against an inside flat side of the hard plates 1031 or 1033 (on the vertical edge side of the wall module 1003) of the adjacent wall module 1003. Along the lateral end face 1022 of the inner hard plate 1021 or the lateral end face 1025 of the outer with the flat side of the hard plates 1031, 1033 of the corner brick 1003 adjacent to the corner formed. The wall panels 1021, the cabin interior side wall panels 1021 and 1031 are preferably the same thickness in their respective transverse direction. The abutting cabin outer side hard plates 1023 and 1033 are preferably equally thick in their respective transverse direction. The transverse direction of the wall module 1002 is provided with the reference Q2 and the transverse direction of the wall module 1003 is designated by the reference Q3.

In the contact region, the wall plates 1002 and 1003 are substantially perpendicular to each other. In this case, a rectangular corner region is formed between the inside flat sides of the cabin-inside hard plates 1021 and 1031. The outer flat side of the cab outside hard board 1023 is flush with the front side the cabin exterior hard board 1033 aligned. 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 1025 and 1035 are so far beyond the respective cabin-inside hardboard 1021 or 1031 in the respective horizontal direction that the insulation board 1025 abuts the end face of the insulation board 1035, so that in the corner region of the wall segment, the insulation boards 1025 and 1035 free of space, more precisely cavity-free, meet. Between the insulation boards 1025 and 1035, a full-surface contact contact is formed along the front side of the insulation board 1025.

The insulation board 1035 abuts the inside of the cabin exterior hardboard 1023 of the other wallboard 1002 at the end. The space between the cabin interior side wallboards 1021, 1031 and the cabin exterior side wallboards 23, 33 is completely filled by the insulation boards 1025 and 1035. The insulating panel 1035 extends over the entire transverse width of the insulating panel 1025 of the other wall module 1002, so that there is a 100% overlap. The insulation board 1025 protrudes horizontally beyond the end face 1022 of its cabin interior side wall plate 1021, so that the end face of the insulation board 1025 is in touching contact with the inside of the insulation board 1035.

In Fig. 3 it can be seen that on the inside or flat side of the cabin inside wall panel 1031, a contact area 1032 is defined by the area where the horizontal end face 1022 of the cabin inside wall panel 1021 abuts against the cabin inside hard panel 1031 of the other wall unit 1003. Similarly, in the inside of the cabin exterior side wall panel 1033 of the wall module 1003, a contact surface 1034 is defined by the area where the horizontal end face 1024 of the cabin exterior hard panel 1023 of the wall unit 1002 abuts.

In the contact areas fasteners are provided, which are shown in Fig. 3 by way of example by male connector 1083 of the wall module 1002 and female connector components 1084 on the inner sides or flat sides of the wall module 1003. The fasteners may be, for example, Owotech connectors. The extension of the connector in the transverse direction of the block, on whose front side it is provided, is smaller than the respective width of the hard plates 1021 and 23, in which they are inserted. The connectors allow a simple insertion and / or insertion connection of the two wall blocks 1002 and 1003 together. For example, the sleeve-like male fastener component 1083 may first be inserted horizontally into respective connector components 1084 and then through a translational relative movement of the wall blocks 1002 and 1003 locked to each other and / or secured.

Preferably, the cabin-inside hard plates, the insulation boards and the cabin exterior 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 resin, a glue or the like, 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.

The passage opening 37 is designed as a through-hole or -milling and has a smooth passage opening inside, in particular without thread. It will be understood that the passage 37 is formed at a port entrance 41, i. near a wall structure surface 45, flattened, as beveled, may be, for example, to avoid sharp edges.

The passage opening 37 extends in accordance with FIG. 2 transversely, in particular in a straight line, preferably without steps, from a soundproof booth outside 49 in the direction of a soundproof booth inside 53. The passage opening 37 extends completely through the ceiling panel 25. This means that the passage opening 37 extends from a cabin-side wall structure surface 51 to a cabin exterior-side wall structure surface 45. However, it is also possible that the passage opening 37 does not extend completely, but only partially, for example to 50%, 60%, 70%, 80%, 90% or 95%, through the ceiling plate 25 therethrough. An opening cross section of the passage opening 37 may be formed, for example, round, oval or angular. 2, a round opening cross-section is provided so that a circular cylindrical passage opening 37 results.

The ceiling plate 25 may have an identical structure as the wall blocks 9. According to FIG. 2, the ceiling panel 25 consists of a multi-layer structure with a rigid panel 57 facing the soundproof cabin interior 3, for example made of plywood, and an insulating panel 61, for example of wood fiber material, arranged above the rigid panel. Thus, the ceiling plate 25 has a composite structure. As can be seen in FIG. 2, the insulating panel 61 and the rigid plate 57 of the ceiling panel 25 have the same base area in at least one plane, preferably the horizontal plane. This means that the insulation board 61, the rigid plate 57 completely covered to ensure over the entire base surface of the rigid plate 57 a multi-layer structure.

The supply air and / or exhaust air system 33 is placed in the embodiment of FIG. 2 on the ceiling plate 25 in order to achieve a compact and structurally simple construction, since no additional holding or stowage units are mounted on the building interior floor or on one of the side wall modules 9 have to. It is clear that an additional, not shown, insulation plate, for example made of plastic, for electrically insulating the circuit protection cabin wall structure 5 above the insulation board 61 may be arranged. If the insulation board 61 already consists of an electrically insulating material, an additional insulation board (not shown) can be dispensed with.

The supply air and / or exhaust air system 33 comprises a pump 65, for example a suction or pressure pump, and an air filter 69 arranged in the air conveying direction upstream of the pump 65 for filtering out, for example, dust particles from the air. The air filter 69 and the pump 65 have, according to FIG. 2, a common housing 73.

In a preferred embodiment, a particularly flexible ventilation hose 77 connects the supply air and / or exhaust system 33 with the passage opening 37. At an axial end of the ventilation hose 77, measured in the air conveying direction, this has a preferably rigid mounting portion 81 which is complementary in shape to the passage opening 37 is formed to connect the ventilation hose 77 by means of the mounting portion 81 in the through hole 37. The mounting portion 81 may be compared to an inner diameter of the through hole 37 has a slight radial excess, preferably of a few millimeters, in particular of 1 mm, have in order to avoid unwanted relative axial movement between the ventilation hose 77 and the passage opening 37 as far as possible.

The vent hose 77 of Fig. 2 is substantially circular cylindrical, i. with a circular cross-section, formed, wherein depending on the shape of the passage opening 37 also further cross-sectional shapes are conceivable. At an axial end 85 of the mounting portion 81, this has one in the radial direction of the ventilation hose 77, i. perpendicular to the air conveying direction of the ventilation hose, via a mounting portion outside diameter projecting mounting projection 89 for defining an axial mounting end position of the ventilation hose 77 in the through hole 37. When mounting the ventilation hose in the through hole 77 of the mounting projection 89 serves as a stop and is in the final assembly position on the wall structure surface 45 on. The mounting projection is formed as shown in FIG. 2 as a preferably closed annular flange whose outer diameter is greater than the passage opening inner diameter.

Furthermore, a silencer 93, such as a telephony silencer or a pipe silencer, is connected to the supply air and / or exhaust air system 33 and the ventilation hose 77. Alternatively, the ventilation hose 77 may also be omitted and the muffler 93 connected both directly to the supply air and / or exhaust system 33 and to the passage opening 37. At the axial ends of the muffler, in each case a connecting sleeve (not shown) for connection to the supply air and / or exhaust air system 33 or to the ventilation hose 77 or the passage opening 37 may be attached. It is clear that the respective connecting sleeve (not shown) is adapted to the shape of the corresponding connecting part, in particular in a form-complementary manner. By way of example, the muffler 93 has an outer diameter of about 130 mm, wherein other outer diameters are conceivable. As can be seen in particular in FIGS. 5, 6, both the ventilation hoses and the mufflers can have a curved course. This means that the ventilation hoses or the muffler can extend at least in one plane, ie two-dimensional, curved, whereby a three-dimensional course is possible. This makes it possible to respond flexibly to the cabin environment, for example, in the immediate vicinity of the cabin located pipes, cable guides or fire detectors, which are usually attached to cover building, avoid. The housing 73 for the pump 65 and the air filter 69 is, as can be seen in particular in FIG. 6, preferably formed as a flat cuboid whose dimension in the vertical direction is smaller than the dimensions in the horizontal direction. The soundproof cabin 1 also has at least one further passage opening 97 in the wall structure 5, ie in the ceiling panel 25 according to FIG. 2, which is designed to connect a second ventilation hose 101. Preferably, the at least one further through opening 97 is identical to the above-described at least one through opening 37 is formed. In particular, the second ventilation hose 101 is identical to the first ventilation hose 77 already described. This means that the preferably flexible second ventilation hose 101 comprises a particularly rigid mounting portion 105, which is configured complementary to the shape of the at least one further through opening 97. Furthermore, the mounting portion 105 may have a slight radial excess, preferably of a few millimeters, in particular of 1 mm, relative to an inner diameter of the at least one further through opening 97. At a mounting portion axial end 109, a mounting projection 113 protruding radially beyond a mounting portion outer diameter may axially secure the second vent hose 77 in the at least one further through hole 97. The mounting projection 113 is formed as shown in FIG. 2 as a preferably closed annular flange whose outer diameter is greater than the inner diameter of the at least one further passage opening 97. In a further development, the second ventilation hose 101 connects the at least one further through opening 97 with a second silencer 117, which is in particular identical to the first silencer 93 already described.

The second silencer 117 may at a first axial end a first connecting sleeve (not shown) for connection to the second ventilation tube 101 provided in the at least one further through opening 97 and at a second axial end a second connecting sleeve (not shown) for connection to a third, in particular have identically formed, ventilation hose 121. Preferably, no supply air and / or exhaust air system is connected along the air conveying path through the at least one further passage opening 97. In order to ensure effective air circulation between the soundproof cabin interior 3 and the cabin environment, the at least one further through opening 97 ostensibly serves as ventilation or exhaust air duct when the supply air and / or exhaust air system 33 is at least superficially designed to supply the cabin interior 3 with fresh air from the outside.

A cover plate 123 or cover plate with in particular identical base surface as the ceiling plate 25 is arranged above this as shown in FIG. 2 and includes the over the ceiling plate 25, and also on the supply air and / or exhaust system 33, protruding wall blocks flush. The Abdeckblende 123 acts as a kind of cover for one of the ceiling plate 25 and the laterally around the ceiling plate 25 around and arranged on this protruding wall blocks 29 (not shown in Fig. 2) formed space 127, in which the supply air and / or exhaust system 33 is located. In the embodiment according to FIG. 2, all the components connected to the supply air and / or exhaust air system, such as ventilation hoses 77, 101, 121, mufflers 93, 117 and connecting sleeves (not shown) are located in the cover panel 123, ceiling panel 25 and To ensure the exchange of air or the air circulation, the cover 123 has a through hole 131 for connecting the third ventilation hose 121 and a through hole 135 for connecting the supply air and / or exhaust system 33. The through-openings 131, 135 of the cover panel 123 are in each case adapted to the shape of the corresponding connection part in order to ensure simple assembly.

The ventilation hoses 77, 101, 121 have a flexible intermediate section 79 immediately adjacent to the respective mounting section 81, 105, 139, which in a longitudinal direction, i. Axialrichtung, the respective ventilation hose 77, 101, 121 retractable and retractable. The ventilation hoses 77, 101, 121 can therefore be compressed and pulled apart in the longitudinal direction in order to achieve different hose lengths and / or to bridge distances of different lengths. This has the advantage that a flexible connection to connection parts is ensured. Furthermore, the ventilation hoses 77, 101, 121 can be bent or curved in the area of the flexible intermediate section 79, so that the side of the intermediate section 79 pointing to the center of curvature is compressed and the side of the intermediate section 79 facing away from the center of curvature is pulled apart. In this way it is possible to form the ventilation hoses shown in FIG. 2, enclosing a 90 ° angle with respect to any spatial axis. The third ventilation hose 121 connected to the ventilation hose opening 131 has immediately adjacent to the intermediate section 79 a preferably rigid mounting section 139, which is adapted in shape to the ventilation hose opening 131, in particular in a form-complementary manner. Further, a mounting projection 143, which is formed in particular as an annular flange, defines at an axial end of the mounting section 139 an axial mounting end position of the ventilation hose 121 with respect to the cover panel 123.
