    description
    The invention relates to an arrangement for distributing gaseous and liquid media in a laboratory and to a method for assembling such a device according to the preamble of claims 1 and 10.
    In building technology, ceiling structures are known to be used for the establishment of research laboratories such as chemical or physical research, in which the supply lines for exhaust air, supply air, the technical gases, liquids, power and data lines required in the laboratory, etc. within the ceilings are fastened directly to the corresponding building ceiling with the help of suitable fastening devices using dowels. Since the laying of the lines is usually carried out one after the other by different personnel, the difficulty arises that the course of the lines is sometimes not only criss-cross and alternately in several levels, but also afterwards due to the individual assembly of the fastening devices only very complex spatial changes can be made to an existing laboratory arrangement.
    From EP 1 934 414 B1 a ceiling construction for a laboratory room is known in which the gaseous and liquid media as well as electricity are routed in an orderly manner in parallel main supply lines in the area of the laboratory ceiling, which are received on a support frame made of profiled beams are. From the main supply lines, the various media are routed via flexible branch lines that can be connected to the supply lines via quick-release couplings to the respective media, which are accommodated above the laboratory tables at the corresponding workstations on the underside of the support frame.
    Although the ceiling construction described above offers a variety of advantages over conventional laboratory ceilings with a disorderly management of the media lines, this results in the problem that the supply of the respective jobs takes place exclusively via the hanging media columns, and the supply of media to the Fittings on the laboratory tables are not made via the tables themselves, but only via the lines hanging down from the media columns.
    DE 1857988 U1 describes an arrangement for supplying laboratory workstations with different media, which comprises a fixed, narrow wall element which is arranged between vertical profiles. In the wall element, the respective media, which are fed to the wall element within the profiles from the ceiling of the laboratory, are guided in parallel, superposed horizontal lines, from which branch pipes extend to the taps for the media located above the respective laboratory tables respective vertically extending support profiles are arranged in boxes on the back of the wall elements. Due to the construction with vertical standing profiles that extend from the floor of the room to the ceiling of the same, the arrangement described is complex to assemble and has little flexibility with regard to a subsequent positioning of the fittings and taps for outputting the media on the wall element.
    Accordingly, it is an object of the present invention to create an arrangement which allows the same extremely flexible routing within a laboratory between the workplaces, and which can also be retrofitted in already existing laboratories in a very short time and with little effort and can be flexibly expanded and converted.
    According to the invention, this object is achieved by an arrangement having the features of claim 1.
    A further object of the invention is to provide a method for assembling such an arrangement with which it can be installed in a laboratory in a particularly cost-effective and time-efficient manner.
    According to the invention, this object is achieved by a method having the features of claim 10.
    Further features of the invention are described in the subclaims.
    According to the invention, an arrangement for supplying liquid and / or gaseous media to workstations arranged in rows in a laboratory comprises at least one standing modular wall element to which the media are supplied from main supply lines running in the area of the ceiling of the laboratory via vertical supply lines . The wall element along which the workplaces are arranged in one row or two rows back to back and which can have a width of e.g. 100 mm or 200 mm and a height of e.g. 90 cm and a length of e.g. 90, 120, 150 and 180 cm, has a back on its upper side, on which one or more media boxes can be arranged, each of which has different removal fittings for the various media, via which they can be dispensed for use in the laboratory.
    The media boxes are fed to the media via horizontally extending connection lines guided within the wall element, for which each of the removal fittings of a media box is connected via a corresponding vertical connection line to the associated horizontally extending connection line for the respective medium, which is located within the wall element of the respective media box extends in the downward direction.
    The inventive arrangement is characterized in that the media box or media boxes can be positioned on the back of the wall element in different positions and releasably fixed in the desired positions and that the vertical supply lines are guided within a console which extends in the vertical direction extends from the ceiling of the laboratory room down to the back of the wall element. The media boxes are preferred
    freely slidable on the back of the wall element or elements, which makes it possible in an advantageous manner to place the media boxes after setting up additional laboratory devices on the tables in positions where the removal fittings are freely accessible from the front and not through the newly installed devices are covered.
    Here, the vertically extending lines at the upper end of the console are preferably fixed by so-called bulkhead screw connections on this and protrude at the lower end of the same up to the intended horizontal installation height of each medium from this. The bracket, which is preferably cuboid in shape, is preferably manufactured as a unit at the factory and is simply placed on the wall element at a desired position when the arrangement is installed and mechanically connected to it, e.g. by means of screws. Alternatively or at the same time, however, the console can be attached to this wall in the case of single-row workstations in which the modular wall element is set up on a wall of a laboratory room. Alternatively, in the case of two-row workstations that are separated by wall elements set up freely between them, the console can be hung on a support frame or on the ceiling of the laboratory room, which enables particularly time-saving and stable installation.
    According to the invention, the guided inside the console vertical supply lines, which extend at the lower end of the console into the interior of the wall element, at their lower ends on first self-closing T-shaped connection adapters. In a similar way, the free ends of the vertical connection lines, which are led from the media boxes from above into the interior of the wall element, are each provided with a second T-shaped connection. This is preferably designed as a known T-shaped threaded pipe connection, which is connected via a conical crimp connection to the respective ends of the horizontally running connecting line and the free ends of the second vertical connecting lines, which lead to the respective removal fittings of the media boxes.
    At the T-shaped connections of the media boxes furthest away from the console, the open outlets of the T-shaped connections can be closed in this embodiment by known end caps, which are also placed on the outlets by means of a compression fitting and close them with a metallic seal. The use of T-shaped pipe screw connections results in the advantage that the modular wall element can be expanded with additional media boxes in a simple and inexpensive manner, or a number of wall elements can be expanded with a subsequently added wall element. To do this, the other wall element only needs to be attached to the floor without cables and equipped with another media box. Subsequently, preferably only the horizontally running connecting lines for the media to be output in the further media box are cut to length, the end caps on the pipe screw connections of the previously last media box are removed and the free ends of the further horizontal media lines are inserted into the associated free outlets and using the compression fittings connected.
    Alternatively, according to a further, more expensive embodiment of the invention, the second T-shaped connections can also be designed as self-closing T-shaped connection adapters, which in the latter case are preferably identical to the first T-shaped connection adapters and the respective Seal the outflow liquid-tight if no further complementary adapters are connected.
    In order to obtain a flow line connection between the respective removal fittings of the media boxes and the connection lines running horizontally inside the wall element, preferably with a double S-stroke, the latter have a complementary connection adapter at one end, which is preferably tool-free according to Art a quick-release coupling or, in the case of high-purity gases, can be screwed on to form a metallic seal. The connection of the vertical first supply lines with the media boxes on the right and left side of the console is preferably done by plugging the respective complementary connection adapter of the horizontally running connection lines onto the self-closing outlets on the right and left side of the first self-closing T-shaped connection adapter below the console. The described self-closing T-shaped connection adapters are known from the prior art and are manufactured, for example, by the applicant.
    As far as in the context of the present application of horizontally extending connecting lines, this is used only to linguistically differentiate the lines from the lines guided within the console and the vertical connecting lines to the media boxes, and also includes lines that are not straight , but eg in a vertically extending plane in an arc-shaped, S-shaped or double S-shaped manner.
    The invention has the advantage that the space between two rows of head-to-head laboratory workbenches can be used effectively to distribute the liquid and gaseous media supplied via the main supply lines in the area of the ceiling of the laboratory room, as well as electricity without the need for individually manufactured and therefore expensive laboratory furniture in which the lines are laid individually in order to conduct the respective media to the associated connection fittings in the respective laboratory workbenches.
    The use of self-closing first T-shaped connection adapters at the lower ends of the vertical leads guided in the console has the further advantage that the console is positioned at any point on the modular wall element and the media concerned can be accessed by plugging the complementary connection adapter horizontal connecting lines can be routed extremely flexibly to media boxes on the right and / or left side of the console. Furthermore, the relevant branch can in the event of a leak
    ge can be disconnected and shut down in a very short time by pulling off the complementary connection adapter, without having to provide shut-off valves in the wall element or the console in a complex manner, which take up additional space and cause costs.
    Another advantage of the arrangement according to the invention and the method according to the invention is that the media boxes, in which the removal fittings for the respective media are received, move within a very short time and with little effort to another position on the back of the wall element in order to supply the affected workplaces with the desired media after a renovation of the laboratory. It is a particular advantage of the invention that the previously laid, straight or curved, S-shaped or double S-shaped supply lines in the wall element due to the use of self-closing first T-shaped connection adapters at the lower ends of the vertically inside The feed lines guided by the console can be detached without the medium escaping. Thanks to the preferred routing of the lines with a double S-shaped section, the media boxes can also be easily moved by approx. + -50 cm on the horizontal support of the wall module if necessary. This has the advantage that the media boxes can be positioned at a different location within a very short time, at which they are not covered by other laboratory devices if these are subsequently placed on one of the laboratory tables.
    The modular wall element according to the invention, which can have a length of 90, 120, 150 or 180cm or a specific length, for example, is preferably made up of known structural profiles with longitudinal grooves arranged therein, for example extruded aluminum profiles that are inserted into the grooves Connecting elements are connected to one another in a known manner to form a cube-shaped support structure fetching inside, on the outside of which large-area plate-shaped front and rear panels are preferably detachably attached without tools via connecting elements engaging in the grooves. The cladding can for example consist of wood or also of sheet metal or plastic and can alternatively be attached to the profiles of the cuboid support structure via hinges or permanent magnets arranged on their inside or in some other known way without tools. This opens up the possibility that the horizontally running connecting lines laid in the interior of the cuboid support structure are freely accessible from the outside in a very short time, for example in order to add further media and their lines.
    In order to close the openings arising on the top on the back of the wall element after relocating the media boxes, or to provide such openings for inserting the media boxes with the vertical connection lines connected to them, it is according to another idea on which the invention is based provided that plate-shaped cover elements are arranged on the back of the wall element, ie preferably on the upper two longitudinal profiles of the cuboid support structure, which can be releasably attached to the wall element to close the openings in the area of the back of the wall element. The cover elements can be made of plastic, wood or metal, for example, and can also be fixed on the top of the back using permanent magnets, so that they can be removed from the top of the cuboid support structure without the use of a tool, or in a different position on it can be positioned. The covers are preferably designed in lengths of 10, 15 and 30 cm and thus, in a particularly advantageous manner, allow the media boxes to be moved in 5 cm steps without cutting new special covers. The openings created by moving the media boxes in steps of e.g. 5 cm on the top of the back are closed in a particularly sustainable way by moving the adjacent cover elements accordingly, without the cover elements having to be separated for this purpose.
    As an alternative to a magnetic attachment, the cover elements can, however, also have elastically deformable engagement elements, for example two or more laterally protruding arms made of an elastic material, which can engage with their hook-shaped ends, for example, in the grooves of the profile strips to fix the cover elements to the profile strips to be brought into engagement with these in the manner of a clip connection.
    Furthermore, it can be provided that the first self-closing connection adapter at the lower ends of the vertically extending supply lines, viewed in the vertical direction, are each offset at a distance from one another. The distance between the first self-closing connection adapters arranged at different heights can be, for example, the height of an inserted T-shaped connection adapter for the respective medium, so that sufficient space is created for each of the first self-closing connection adapters at the lower ends of the vertically running supply lines to accommodate the first self-closing connection adapters To connect the T-shaped connection adapter with the complementary connection adapters and to guide the lines altogether without crossing.
    In the same way, in the preferred embodiment of the invention, the T-shaped screw connections at the lower ends of the vertical connection lines, which spring from the removal fittings of the media boxes, viewed in the vertical direction, are each arranged at a distance from one another in such a way that the horizontally running connecting lines for the respective liquid and gaseous media can be guided in planes running parallel to one another within the wall element. With this embodiment of the invention, in connection with a straight or curved or S-shaped line routing within the wall element, a particularly structured arrangement of the lines is obtained, which in the case of an exchange or an extension of the wall element by a preferably identical one arranged, for example, on the end face of the wall element another wall element enables a particularly simple and quick assembly of the same.
    According to a further idea on which the invention is based, it can, as already stated above, alternatively be provided to manufacture one or more of the horizontally extending connecting lines from a flexible material and to double them within the wall element along an arched, S-shaped or double S-shaped line path to lead. This opens up the possibility, starting from an initially central position of a media box, in which the horizontally running connecting lines are laid e.g. along a simple S-shaped line path, this media box with very little effort, for example by + -50cm in both directions on the back of the Wall element can be moved, which leads to the fact that the curved or simply S-shaped line path is stretched to a straight line path, or is compressed to a double S-shaped line path.
    This further increases the flexibility in setting up the laboratory workstations and advantageously reduces the time required to move the media boxes onto the back of the wall element, since no lines have to be lengthened or shortened. There is also the advantage that the media boxes can also be moved by untrained personnel, since no line connections have to be opened or reconnected.
    In the case of pressure lines, such as those used for the distribution of the gases and liquids used in a laboratory, such as argon, helium, propane or water and compressed air, a previously described arcuate, S-shaped or double-S -shaped conduit path, these can be designed in particular as soft copper pipes, steel flexible lines or as plastic hoses. At the same time or alternatively, the vertical connection lines can also be designed as flexible lines with a curved or S-shaped line path in the manner described above in order to enable the media boxes to be shifted along the back by a certain distance of e.g. 20 cm to the right or left without that the horizontally running connecting lines for the respective media within the wall element have to be replaced by shorter or longer lines.
    In the preferred embodiment of the invention, in addition to the vertical feed lines and horizontal connecting lines for the liquid and gaseous media in the console, a vertically extending round cable in the wall element can be guided to a flat ribbon cable extending horizontally in the wall element. The electrical connection from the round to the flat cable is extremely space-saving with an electrical connection element in which pointed screws are screwed into the connection of the conductors through the insulation. In the same, reverse manner, the connection is made from the horizontal ribbon cable to round cables, which are used, for example, to supply electrical modules in the media boxes, which preferably have one or more power sockets and possibly other electrical components such as FI fuses and transformers to supply USB Connections etc. may contain.
    A particular advantage of the method described above for the flexible connection of electrical modules can be seen in the fact that further electrical modules or other electrical under-table installations can be connected afterwards with very little effort.
    In the preferred embodiment of the invention, the second multi-core electrical line is designed as a ribbon cable, which has a rectangular cross-section with parallel electrical wires that are surrounded by an elastic insulation material, such as plastic. The parallel electrical wires run along a longitudinal plane, which in turn extends parallel to the flat side of the electrical line. In this embodiment, the electrical connecting element has a number of mandrel-like contact pins that are assigned to the number of electrically conductive cores and are arranged in parallel next to one another, which are used to establish an electrically conductive connection in a direction perpendicular to the longitudinal plane in the direction of the parallel cores guided in the longitudinal plane a sufficiently large force can be applied to pierce the elastic electrical insulation material. This has the advantage that the multi-core electrical line can be installed horizontally within the wall element and / or the console, and a desired electrical connection to the electrical connection lines of the media boxes and / or to another horizontally running, multi-core electrical line configured in the same way can be produced, e.g. B. to expand the row of workstations with another modular wall element.
    According to a particularly advantageous embodiment of this embodiment, the first, in the console from the ceiling of the laboratory downward electrical vertical supply line arranged within the wall element, and extending in the horizontal direction angled portion on which the electrical connecting element is mounted, which carries the spike-like, spike-like contact pins assigned to the respective wires, which penetrate the electrical insulation of the second horizontal electrical line to produce the desired electrical connection between the wires of the first vertical electrical line and the wires of the second horizontally extending electrical line. This flat and angled embodiment of the end of the first vertical electrical supply line has the advantage that it can be transferred very easily in an arc from the vertical to the horizontal without the risk of a cable break.
    In the case of data lines that are used to supply the respective jobs with network access, it is provided according to a further advantageous embodiment of the invention, at the lower end of the Kon
    sole to install an active microswitch centrally, which has four outputs, and to provide a further microswitch with four outputs in each of the media boxes, which have an approx. 3m long patch cable. The patch cables from the media boxes can thus simply be plugged into the central microswitch below the console. This embodiment of the invention has the advantage that all connected media boxes can be provided with several network sockets despite the tight space conditions when using very narrow wall elements with a width of, for example, only 100 mm Media box or the wall element must be connected in a star shape to the central switch via a separate network cable, which is not possible or only possible with great effort for reasons of space with the mentioned depth of the wall element.
    According to a further idea on which the invention is based, a method with which the above-described arrangement can be installed in a laboratory in a particularly simple manner and in the shortest possible time comprises the following method steps:
    First of all, the wall element is set up in the desired position within the laboratory, and there it is fastened to the floor of the laboratory, for example by means of a screw connection or in some other way, for example with the aid of suction cups or the like. Alternatively, it is also possible to screw this to an existing building wall. In this context, there is a particular advantage if initially only the empty wall modules are installed without the lines contained therein, and then only the relevant horizontal connecting lines are installed in the manner described above, which are required for supplying the media to a media box, since As a result, the number of lines to be pulled in can be reduced considerably compared to wall elements in which all lines have already been pulled in, so to speak, in reserve, which saves installation space and lowers costs.
    In a subsequent step, the media boxes with the vertical connection lines and second T-shaped connections for the gaseous and liquid media, and possibly with the electrical cable with ribbon connection and the patch cable for communication, are installed at the desired locations positioned on the back of the wall element and fixed there, for example, with the aid of sliding blocks and screws engaging in the grooves of the profile supports described above.
    If the media boxes are seated in the intended position on the back of the wall element, the horizontal connecting lines are drawn into the wall element and their ends facing away from the console are connected to the T-shaped connections at the ends of the second vertical connecting lines with the aid of the aforementioned crimp connections. The horizontal connecting lines are preferably designed as flexible lines which have a length that is greater than the distance between the second T-shaped connections and the first self-closing T-shaped connection adapters.
    When assembling the wall elements, it is a great relief for the fitters if the at least one media box, or the media boxes, can be moved, in particular slidable, on the back of the wall element at predetermined grid intervals of in particular 5 cm, and different cover elements are used which have a length which corresponds to an integral multiple, in particular double, triple or six times, the specified grid spacing. In the preferred embodiment of the invention, the grid spacings are 50 mm, and the upper plate-shaped cover elements, which can preferably be fixed on the back of the wall element by locking means or magnets or in some other way, have a length of preferably 100, 150 and 300 mm, so that after the Moving the media box (s) resulting openings can be closed by simply repositioning the cover elements.
    In conjunction with the aforementioned flexible horizontal connecting lines, which are excessively long and therefore do not run horizontally in a straight line, but rather are designed in a curved or S-shaped manner as described above, this enables the media boxes to be moved by a good 50 cm in steps of 5 cm without re-laying the cables. This advantageously allows a quick and highly flexible correction of the position of the media boxes or of the console relative to the wall element to be carried out afterwards, whereby planning errors can be corrected inexpensively and inconspicuously afterwards.
    In a final step, the complementary connection adapters of the horizontally running connection lines for the respective media, which are already connected with their one end to the T-shaped connections on the vertical connection lines of a relevant media box, with their associated complementary connection adapter on the outlet of the self-closing first T-shaped connection adapter for the medium in question. Due to the self-closing properties of the first T-shaped connection adapter, the flow connection to the media boxes is only released after the complementary connection adapters have been fully inserted.
    The invention is described below with reference to the drawings using preferred embodiments. In the drawings show:
    1 shows a schematic three-dimensional representation of the arrangement according to the invention with three media boxes,
    and
    2 shows a schematic, semi-transparent front view of the arrangement according to the invention with three
    the back of the media box (s) mounted on the modular wall elements.
    1 and 2 show an arrangement 1 according to the invention for supplying liquid and / or gaseous media 2 to workplaces 4 in a laboratory, which are arranged next to one another in a known manner in rows. The media 2 are here supplied from main supply lines 6 routed in the area of the ceiling of the laboratory via vertically routed supply lines 8 to at least one standing modular wall element 10, which extends along a row of workstations 4. As shown, the work tables of the workplaces 4 are preferably placed head-to-head with their backs on the front and back of the wall element 10, which has a back 12 on its upper side, on which media boxes 14a, 14b, as shown, correspond to the number of workplaces along the Are arranged in a row. Each of the media boxes 14a, 14b has a large number of removal fittings 16, such as self-closing fittings, sockets and taps for the respective technical gases, liquids and compressed air that are required at the respective workstations 4. The media boxes 14a, 14b can, for example, have a width of 300 mm, a depth of 100 mm and a height of 300 mm and can be individually equipped with the desired removal fittings 16 and prefabricated as independently manageable units.
    As can be seen from the semi-transparent representation of FIG. 2, the respective media 2 are supplied to the extraction fittings 16 via horizontally extending connecting lines 18 which are guided within the wall element 10 and which are guided along an S-shaped path, each extraction Fitting 16 of a media box 14a, 14b is connected via a vertical connection line 20 to the associated horizontally running connecting line 18 for the respective medium 2, which extends downward within the wall element 10 from the media box 14a, 14b.
    The media boxes 14a, 14b can be positioned and fixed on the back 12 of the wall element 10 in different positions, for which each wall element 10 has a support structure with two parallel profile strips 10a, 10b, which are positioned vertically between two unspecified ones Posts on the front and back of the modular wall element 10 extend. The media boxes 14a, 14b have at least one base plate and are snapped onto the profile strips 10a, 10b, preferably with the aid of engaging elements received on the base plate, or fastened with the aid of slot nuts and screws.
    In order to close after the assembly of the media boxes 14a, 14b the openings 11 remaining between these in the region of the back 12, one opening of which is indicated, for example, in FIG. 1 in dashed lines, plate-shaped cover elements 32 are provided which are placed on the The back 12 of the wall element 10 can be snapped on and slidably supported thereon. For this purpose, the plate-shaped cover elements 32 have engagement elements 32a on their underside, which are designed to be resilient and engage in grooves or depressions, not shown in detail, in the profile strips 10a, 10b, or engage below them in a form-fitting manner on their underside.
    As can also be seen from the representations of FIGS. 1 and 2, the vertical supply lines 8 are guided in a bracket 22 which extends from the ceiling of the laboratory to the back 12 of the wall element 10 down. The vertical feed lines 8 are led out of the bracket 22 with their lower free ends 8u and extend into the interior of the wall element 10 after the assembly 1 has been installed. The vertical feed lines 8 have at their free lower ends 8u first self-closing T-shaped connection adapters 26, which are arranged on different levels for the respective media 2 as shown in FIG.
    In the same way, the free ends 20u of the vertical connection lines 20, which lead to the media boxes 14, each have a T-shaped connection 28 for each medium 2, these second T-shaped connections 28 at a distance from one another in different planes are arranged, which correspond to the planes in which the first self-closing connection adapters 26 are arranged. The positioning of the first self-closing T-shaped connection adapter 26 as well as the second T-shaped connections, which are designed as compression fittings, is preferably carried out in such a way that the adapters 26 and connections 28 are each arranged in a horizontal plane and in the depth direction of the wall element 10 lie in pairs in spaced-apart vertical planes running parallel to one another, in which the S-shaped line paths of the connecting lines 18 then also run.
    In order to establish a flow connection between the first self-closing T-shaped connection adapters26 and the second T-shaped connections 28 for each medium 2, the associated horizontally extending connecting lines 18 in the wall element 10 each have one at their ends below the console 22 complementary connection adapter 30, which can be inserted into the self-closing outlets of the first T-shaped connection adapter 26 for the respective medium 2 in order to establish a flow connection.
    As can also be seen from Fig. 2, in the preferred embodiment of the invention, in addition to the vertical feed lines 8 and horizontal connecting lines 18 for the liquid and gaseous media in the console 22, a vertically extending first multi-core electrical line 40 and in Wall element 10 one with this
