Description

 Suspended ceiling system

The invention relates to a suspended ceiling system, comprising a plurality of ceiling elements, which are arranged essentially in a horizontal plane, and have means for fastening the ceiling elements to a floor ceiling or a wall, the ceiling elements comprising a frame, the upper and lower boundaries of which flat is covered by a stretched and at least partially transparent film

A large number of suspended ceiling systems are known in practice, in which a plurality of generally square ceiling elements are installed vertically at a distance from a floor ceiling. For this purpose, a scaffold designed in the manner of a supporting grid is often firmly anchored to edge supports or via connections to the floor ceiling and individual ceiling elements placed on this scaffolding The ceiling elements are mostly flat and can be lifted out of the scaffolding without difficulty, which is an advantage if repairs to cables between the floor and suspended ceiling are to be carried out. The lighting of the known ceiling systems is problematic with these known ceiling systems Space below the ceiling system Due to the static requirements, it is usually not possible to attach lights to the ceiling elements themselves, which is why lights often have to be suspended from the scaffolding From an already suspended deck e hanging down lights, however, regularly emit an intense and dazzling light, which also illuminates the room unevenly and is therefore often not wanted Instead, it was proposed to replace individual ceiling elements with flat lights, whereby the luminaire facing the viewer on one Housing is fastened, in which a light source is arranged at the same time. The light generated in this way often appears cold and dirty because the surface is difficult to illuminate and dust and dirt also hinder the passage of light. Finally, it is necessary for such solutions the statics of the grid clearly oversized, so that the ceiling system is expensive to manufacture and purchase overall and tends to bend in large-format ceilings

Suspended ceiling systems are also known from practice, which also consist of a plurality of ceiling elements arranged in the manner of a grid, which have a further element parallel to their surface, which makes it possible to destroy incident sound waves. However, these known systems do not integrate any lighting, and are also very sensitive to any type of lighting fixture arranged on the system, since this is the vibrating mass and thus the sound insulation behavior change

Suspended ceilings are also known in practice, which have a frame encircling the dimensions of the room, on which a plastic film is stretched, the plastic film being translucent and allowing light to pass through, starting from a lamp arranged behind the film, this disadvantage being disadvantageous On the one hand, the construction means that each ceiling must be individually made to the dimensions of the room and therefore the materials required for this cannot be produced in large series.In addition, due to the large clamping forces, this construction requires the frame to be pre-bent, which is only possible with the appropriate machines This means that assembly by the end customer is impossible. In addition, the required foils cannot be produced in any size, so that seams are visible on large-sized ceilings where several foils have been connected to each other ACCESSIBLE because the suspended ceiling can not be partially solved

In addition, the disadvantage of all the solutions shown was that, over time, visible dirt deposits formed on the film and led to dark spots and inhomogeneities in the light observed

It is therefore an object of the invention to eliminate the existing disadvantages and to propose a suspended ceiling system which is simple to manufacture and assemble and which enables large-area lighting

This object is achieved in the ceiling system mentioned at the outset in that at least the upper film is designed to be completely closed and is connected to the frame in a dust-tight manner. The ceiling system according to the invention has a plurality of ceiling elements, each of which has its own and closed frame on which two tensioned and foil that is at least partially permeable to light, whereby dirt deposits from below are not visible due to the spacing of the two foils and the use of a second fohe. This ceiling element is preferably square or possibly rectangular and forms the smallest unit of a ceiling system to be stretched in a grid dimension, the The base area of the frame is dimensioned such that the film can be stretched onto the frame without a visible seam. With the ceiling system according to the invention, even large rooms can be provided with an almost continuous luminous ceiling, with low cost de That part of the room that goes beyond a standard grid size is closed with a side panel, or the gap can be closed with custom-made items. The ceiling elements are either attached to a floor ceiling, for example by a hanging bar, or on the side arranged on a wall, in which case an at least partially circumferential support enables storage

The small format selection of the frame makes it possible to produce it automatically on small machines, the clamping forces that bend the frame inwards are so small that the frame can often not be pre-bent in the opposite direction. The ceiling system according to the invention is also very great lightweight, since the film with a thickness of 0.15 to 0.23 mm has a weight of approximately 200 g / m ² and the frame can be made correspondingly lightweight. As a result, the ceiling elements used according to the invention are significantly lighter than previously known luminaire claddings and thus lower the requirements for the means for fastening to the ceiling or wall

A second, lower film is preferably clamped at a distance from and parallel to the first, upper film on the frame or on a second frame parallel to it, the

The space between the two foils is dust-tight. The two foils are spaced between 2 and 6 cm from one another, with one being particularly preferred

Minimum distance of 4 cm is This preferred measure ensures that dust and insects cannot deposit on the upward-facing surface of the lower film, which lead to dark spots or to inhomogeneities in the light observed when the ceiling system is illuminated. The minimum distance mentioned is sufficient to fully illuminate the lower film due to the scattering from the film above it, so that even with larger deposits on the upper film the lower one is homogeneous

Emitting light Expediently, the second film is stretched on the same frame on which the first film is also stretched, so that a closed one is already thereby

Interior space is formed as a result, the distance between the two foils is predetermined and a compact design is achieved

Improved scattering of the light is also advantageously achieved in that at least one film has a pimpled structure on at least one side or that the lower film has microperforation. The pimpled embossing of the film surface or the microperforation results in additional scattering or extensive scattering achieved, which leads to an almost complete resolution of the shadow formation, whereby the illumination of the room can be significantly improved and optimized.The effect of the pimpled structure and that of the microperforation is particularly effective if two spaced foils are used and the foil closer to the light source is equipped with the pimpled structure. The micro-perforation also makes the sound-absorbing properties of the suspended ceiling system special influenced and improved The microperforation can be present in the lower, visible film, for example, in order to optimally utilize the sound-absorbing properties. The openings must be large enough to absorb the sound waves through multiple reflection and interference formation in the space between the films, but must not great that insects can enter

Basically, it is possible to provide the illumination of the space formed under the ceiling system by illuminating the ceiling system from below, optionally by lighting in the floor area or in the area below the ceiling system. However, it is preferable to provide at least one and preferably a plurality of lamps behind the Ceiling elements, with the light rays emanating from the lamps passing through the film Here, a film is expediently used, which is translucent and thus creates a diffuse brightness in the room, which is free of external effects and in particular does not cast sharp shadows of the objects in the The ceiling system is particularly suitable for sales areas or workplaces in which highly reflective objects are arranged, for example screens, display cabinets, polished metal surfaces, glossy lacquer surfaces, and the like amps installed in a fixed relationship to the ceiling elements, e.g. a lamp for one, four or nine ceiling elements, whereby the assignment rule can also include parts of ceiling elements.This standardized assignment enables the required accessories to be determined quickly and at a glance for a given ceiling area and determine their arrangement

A film made of translucent plastic, preferably PVC, is expediently used as the film, the thickness of which does not exceed 0.25 mm. The film used is flexible and can be expanded by about 2% to 6% by tensioning without tearing, which is the reason for the tensioning In addition, and in contrast to known hard plastics or glass used for construction purposes, the film can be made translucent but not transparent, so that the view of the structure of the ceiling system remains hidden when the lighting is switched off. When the lighting is switched on, the film provided advantageously transmits Wide light spectrum including the ultraviolet and infrared wavelengths in the border area to visible light, whereby a plurality of colored light sources can be used for lighting, each of which can be individually influenced in their intensity and different colored illuminants can be used nd, so that a color temperature-controlled lighting on the back of the ceiling system is transmitted completely and without filtering out certain frequency ranges and gives the viewer the impression of natural light particularly effectively. Such light sources emit a frequency and intensity spectrum that corresponds to that of natural light and therefore as special Such is pleasantly perceived Light sources further intensify the scattering effect of the foils, so that the lighting of the room is very similar to natural light. The diffuse emission of light through the foil also distributes the pleasant spectrum evenly, with the uniform illumination of the foils also giving the impression that it is a natural light The aesthetic effect achieved with the aforementioned technical means in a room with a ceiling system designed in this way corresponds to that of lighting a room with so-called skylights, through which the natural light comes in. Here, there is also the possibility of certain color effects by corresponding to generate colored light sources

According to a preferred first variant, the frames of adjacent ceiling elements are laterally connected to one another in the ceiling system, wherein the connection can also be limited to a local connection, so that they can form a surface formed from several ceiling elements, with the fastening means for fastening the ceiling elements the floor or wall is arranged on the frame or can be detached from it.This makes it possible, on the one hand, to form a manageable number of ceiling elements, for example four or nine, into a rather rigid structure in small rooms and to arrange this, for example, on the wall side If the suspension is provided on the floor slab above it, on the other hand it is possible to connect rods, chains or other hanging fastenings hanging from the floor slab with one or preferably two frames, so that the dead weight of the ceiling elements is vertical al is included and a deflection of the ceiling system is prevented. A particular advantage of the arrangement in which adjacent ceiling elements are connected to one another via their frames is the small gap that is not illuminated between two ceiling elements due to their frames

As a preferred alternative variant, it is possible for a mounting rail structure to be arranged on the fastening means, which, for example in the form of an inverted T, provides the horizontal limbs, which go out on both sides of the vertical limb, for the supporting surfaces of the frame a grid concept, because the even weight of the two legs of the mounting rail cheaply transfers the weight of the ceiling elements to the fasteners, thus effectively preventing deflection

For further sound absorption and reduction, it is proposed that a fluffy but translucent intermediate layer be inserted between two films used. Further advantages and features of the invention result from the subclaims and from the following description The invention is explained in more detail below with reference to the accompanying drawings using preferred exemplary embodiments of the invention

6 shows a cross section through a fifth exemplary embodiment of a suspended ceiling system according to the invention

The ceiling system, generally designated by reference numeral 1, consists of a plurality of ceiling elements, generally designated by reference numerals, one of which is shown in cross section in FIG. 1, and a corresponding number of means 3 for fastening the ceiling elements to a floor ceiling, the a support rail 4, which is T-shaped in cross-section, and a support rod 5 connecting the support rail 4 and all other elements of the ceiling system 1 with a floor ceiling, not shown. In the present case, the support rails 4 are illustrated only in the sheet plane. In such an implementation, the ceiling element 2 is essentially Rectangular and extends over the entire depth of the room and thus as a piece over the length of the mounting rail 4 But it is useful if the ceiling element 2 is square and provided transverse to the mounting rails 4 shown rail elements, not shown s, which rest on adjacent support rails 4 on these and separate adjacent ceiling elements in the manner of a panel, so that when viewed from below, the image of a grid results, in which ceiling elements 2 are embedded Such a square ceiling element 2 is indicated in the perspective view of FIG. 2. The ceiling element 2 has a square frame 6, which is designed as a hollow square profile with reinforcing ribs, the frame 6 with a flat side of its square profile predominantly on a horizontal leg of the T- Shaped support rail 4 is stored and only protrudes inward with less than a quarter of its surface over this leg. On its upper surface, which faces away from the surface that is deposited on the leg, a film provided with reference numeral 7 is glued on the edge, the Within the adhesive, which is indicated by reference number 8, the remaining central section of the film 7 completely closes the frame 6 without already exhibiting tension. Reference number 9 denotes a second frame, which is adapted to the dimensions of the frame 6 and is designed as an angular profile, for this purpose certainly is to be positively pushed onto the first frame 6, with both the possibility that the angle profile 9 forms an interference fit with the frame 6 and that a slight play is provided. The angle profile 9 reaches the area with its horizontal leg 9a the adhesive 8 of the film 7 and the frame 6, while the vertical leg 9b on the inside of the frame 6 protrudes downward beyond the cross-section of the frame and the mounting rail 4 and the film 7 expands and tensions accordingly. The outward end of the leg 9b is rounded In order not to damage the film At the same time, the length of the leg 9b is selected such that the stretching of the film 7 remains in a range of approximately 4% due to the application of the angle profile 9. The angle profile 9 and the frame 6 are in the area of the adhesive 8 interlocked by riveting or pinning to prevent the film 7 from bending due to its internal stress il 9 lifts out of its position The resulting ceiling element 2 thus has a tightly stretched film 7, which is free of folds and non-stretched areas and is ready to be installed in order to be placed on a mounting rail 4. The ceiling system 1 can thus be provided by a prefabricated ceiling element 2 , which can be stacked and transported in a simple manner and, if appropriate, also assembled by the end user on site, by appropriate attachment of the fastening means 3. It should be understood that in a room in which a ceiling element 2 is arranged directly adjacent to a vertical wall instead of the T-shaped mounting rail element 4, which is suspended from the floor, an L-shaped angle element can be attached to the wall, the area of which can be seen from below corresponds to that of a horizontal leg of the T-shaped mounting rail element 4 A floor 10, which is essentially not arranged, is arranged on the floor ceiling Lichen is provided centrally to the ceiling element 2 and illuminates it at a corresponding distance. The translucent film 7 leaves the light from the lamp 10, which can also be a plurality of lamps, which is emitted via a temperature field control Light can be matched to one another, the area between the mutually facing vertical legs 9b illuminating the room for the viewer as a homogeneously illuminated surface. It should be noted that the structure selected with a frame 6 and an angle profile 9 means that the lateral protrusion over the Carrier rails 4 turns out very small and essentially makes up the generally negligible thickness of the vertical leg 9b. As far as larger distances are shown in the drawing, this is primarily for illustration, this also applies to the distance between the frame 6 and the vertical leg 9b T-shaped support rail 4, with a smaller distance for game compensation will remain regularly The area between the inward leg 9b of two frames, which are arranged on the same support rail 4, remains dark for the viewer, whereby the viewer with a dark grid as an optical impression very bright illuminated areas, which correspond to the visible area of the film 7, perceives

The ceiling system according to FIGS. 1 and 2 is particularly suitable for assembly by the end user who is not familiar with the manufacture of the ceiling elements, since the film 7 can already be glued to the frame 6 and the tensioning and pinning of the angle profile 9 by possibly already predetermined ones Breakthroughs in a stretched film result without the need for additional tensioning tools. Accordingly, the ceiling element 2 is preferably produced by first producing a circumferential square frame 6 which has an at least triangular cross section, then on one of the sides of the polygon, which is not the support side of the frame 6, a film 7 is glued and in a further step, a circumferential, adapted to the geometry of the frame 6 and this surrounding angle profile 9 is pressed over the frame 6 and film 7, whereby the film 7 is stretched and finally the frame 6 is connected to the angle 9, preferably detachably, in order to produce a stretched film 7 as an interface for a ceiling element 2. This method is also easy for a layperson to understand and the ceiling element 2 produced by the method is immediately ready for use

Fig. 3 shows a further exemplary embodiment of a suspended ceiling system according to the invention, which is basically constructed in exactly the same way as the ceiling system from Figures 1 and 2 and in which, unless otherwise stated, the same parts are provided with the same reference numerals and comparable parts with an apostrophe Suspended ceiling system 1 'from FIG. 3 uses the same means 3 for fastening the ceiling elements as shown in FIGS. 1 and 2, which are therefore not dealt with in more detail. The ceiling element 2' of the ceiling system V likewise has a film T which is circumferentially covered with a piping 8 'is provided, which is a thickening that allows gripping and clamping the film T The film 7' is on one Frame 6 'pulled up, a downwardly projecting circumferential projection 6b' of the frame 6 'serves as a tensioning bar, over which the film 7' is pulled. A clamping or locking lug 9 'of the frame 6' clamps the piping 8 'securely and prevents this from loosening from this anchoring and thus ensures the tension of the film 7 '. The cross section of the frame 6' also has a plurality of flanks and undercuts in the manner of a dovetail, which are designated by 6a ', and make it possible to couple adjacent edges of the frame 6 'to a connecting element which engages in two frames 6' without a support rail structure 3 being required, or to attach the frame 6 'directly to a vertical wall. Also the suspended ceiling system 1 'makes it possible to illuminate large areas of a room via the film 7', the edge region to the mounting rails 4 being selected by the frame mens 6, which protrudes clearly above the mounting rails 4, is darkened and causes a continuously decreasing brightness range for the transition to the complete covering of the mounting rail 4. Such continuous transitions are often perceived as more aesthetic than strong light / dark contrasts

4 shows a further exemplary embodiment of a suspended ceiling system according to the invention, which, in contrast to the previous one, is identified by two apostrophes. The ceiling element 2 "in turn has a square peripheral frame 6" on which a second film 7 "extends over a section projecting downwards 6b "is stretched, the edge region of the film 7" being implemented in the manner of a loop in a recess 6a "made outside the projection 6b, and this recess is clamped with the film then inserted via a clamping strip 8". The clamping strip 8 "is preferably made of an elastomeric material that is anti-slip, whereby a circumferential strip does not necessarily have to be provided, but rather it can be sufficient if larger areas of the edge of the film 7 "are held in this way by clamping on an inwardly directed flank of the recess 6a" is a projection designed like a nose 6c "is provided, which pinches the bar 8" and prevents it from slipping out of the recess 6a "due to the pretensioning of the film 7". Furthermore, it is possible to insert the terminal block 8 "through bores in the region of the recess 6a" by introducing pins (not shown) to lock, which also securely holds a rigid clamping strip 8 ". Furthermore, it is possible to apply an adhesive prior to tensioning, which effectively connects the clamping strip 8", film 7 "and frame 6". The film 7 "is also stretched in the present exemplary embodiment , wherein part of the film 7 ", on which the projection 6b" rests, rests on the horizontal leg of the mounting rail 4, as a result of which the illuminated surface of the film 7 "is used to the maximum

It is alternatively possible to place the area of the strip 8 ″ on the mounting rail 4, and their to shorten the horizontal leg accordingly, which advantageously provides an elastomeric buffering effect of the terminal block 8 "for a favorable fit between the ceiling element 2" and the mounting rail 4 and at the same time prevents wear on the film 7 ". The frame 6" also has on its side facing away from the film 7 " and parallel to the latter on another film 11, which can be the same material as the film 7 ", but does not have to. The film 11 is stretched and clamped or fastened in a comparable manner to the film 7", so that it is not closer to this The film 11 essentially has the task of keeping dirt and falling particles as well as insects and dust away from the area of the film 7 ". Any deposits were only a burden on the top of the film 11, in contrast to that of the frame 6" and films 7 "or 11 surrounding space to keep free of contaminants that would otherwise have been deposited on the top of the film 7" Di e Optical impairment when illuminated by means of a lamp 10, which can occur with such deposits, is effectively prevented, the low weight of the film 11 not making the ceiling element 2 'according to the invention significantly heavier or bulky by the choice of a suitable distance between the two films 7 "and 11 of a little more than 4 cm, it is ensured that impurities on the top of the film 11 are no longer recognizable as such for the observer looking at the film 7" from below, since the scattering of the light as it passes through the film 11 it is sufficient to ensure uniform illumination of the film 7 ", on which no more contamination is caused by the measure according to the invention. A further advantage of the arrangement of the ceiling element 2" according to the invention with two films is then that the illumination of the lower film 7 is improved "Measures have already been taken in the area of the upper fohe 11 can, for example, the provision of light distribution points that scatter light more or bundled. Furthermore, it is possible to effectively eliminate sound waves that are always perceived as annoying in the case of suspended ceiling systems when they are reflected on the ceiling system It is possible to form the fohe 11, which is not visible to the viewer, with microperforations or the like, as a result of which the friction of the sound at these openings ensures that the openings are extinguished. For this purpose, it can advantageously be provided that the frame 6 "with openings in the Bores or slots are provided, which are indicated in the present case by the reference symbol 6d ". These openings can be covered on the inside with a fleece (not shown) in order to prevent the entry of contaminants into the interior of the frame. The provision of bores 6d" also has the advantage that after removing the fleece s the ceiling element 2 "can be flushed out with compressed air, for example, without having to remove the tensioned foal for this purpose, so that, for example, liquid residues which are deposited can be dried out due to the formation of condensate 5 shows a further exemplary embodiment of a suspended ceiling system according to the invention, in which, to distinguish it, the parts which differ from the previous exemplary embodiments are provided with three lines and, moreover, with the same reference numerals. The ceiling element 2 '"also comprises a lower foam 7'" and an upper one Films 11 ', both of which are stretched over projecting webs of the frame 6'". The tension is applied in the same way as in the previous exemplary embodiment, and for the same purpose a clamping strip, not shown, is introduced into a recess 6a""of the frame 6" , wherein the connection between the terminal strip and the recess 6a '"is favorably designed by means of a plurality of grooves in the recess 6a'". The strip 6b '", which is designed in the manner of a projecting leg, extends essentially outwards at an angle of 45 ° to the vertical and below, and thus represents not only the lower, but also the outer extreme of the R Ahmens 6 '"by stretching the fohe 7'" over this leg 6b '"the lower fohe 7'" protrudes to the extreme of the peripheral edge of the frame 6 '", the surface of the leg facing the fohe 7'" 6b '"is designed in such a way that a light incidence on the outer edge of the foam 7"' which is visible to the viewer is still guaranteed. Advantageously, this surface has means for bundling the light falling on it in the edge region of the foam 7 '", thereby the absolutely smaller amount of light that falls there is concentrated by stronger bundling and deflection, so that the area of the fohe 7 '"below the leg 6b'" is also well illuminated. Such a means is, for example, a reflective foal that is applied to the said surface of the leg 6b '"is glued, but it is also possible to evaporate a reflective surface

However, a geometric configuration in the form of a converging lens bent in one dimension, as indicated at 12, is particularly preferred, which can additionally have the surface finish in the manner of a reflector or a mirror. It should be noted that if two ceiling elements 2 '" be arranged side by side, the remaining gap of the adjoining frames 6 '"in the plane defined by the foam 7'" becomes minimal, and is practically imperceptible to the viewer due to the fading effect of the diffusely radiating light, even if a narrow, darker stripe is perceived , the fact that the illumination of the rest of the area is very uniform leads to the fact that the overall aesthetic impression that is to be perceived by the viewer is that of a continuously illuminated ceiling and not that of numerous illuminated ceiling elements 2 '"This circumstance becomes additional supported by the fact that B lighting one or more lamps 10 are provided, which are not necessarily coupled to a ceiling element 2 '", but rather can also illuminate a plurality of ceiling elements 2""at the same time. As a result, the illumination of adjacent ceiling elements 2""does not differ from the absolute amount, so that the joint is not more clearly recognizable by a gradation of the illumination of the foils It is possible Similar to FIG. 4, sound insulation measures for the configuration of the foam 11 'or the frame 6'", that is to say in particular perforations and perforations, are to be provided. The means 3 '" for fastening to a floor ceiling or a wall engage a central and outwardly directed projection 13 of the frame 6 '", this projection 13 not necessarily being circumferential. The projection 13 has at the end a downwardly bent hook section which is intended to engage in an undercut of a support rail 4'". The support rail 4 '"is similar to one turned upside-down T-profile, the horizontal legs are essentially designed from the upwardly bent and at a distance from the space required for the hook. As a result, the width of the support rail 4 '"is very narrow and can accordingly between the abutting frame 6 in the lower area It should be noted that also the outward-facing Flat of the leg 6b '"springs back, so that it is possible to lift a ceiling element 2'" out of engagement with the support rail 4 '"by lifting it laterally with its projection 13 and on the outward-pointing section of the leg 6b'" on the adjacent ceiling element 2 '"to pivot past it is thereby possible to quickly replace individual ceiling elements 2""or to allow access to the parts arranged above the suspended ceiling system 1"", for example the lamps 10, without removing the entire ceiling similarly to the mounting rail 4'", which is hooked onto a support rod 5 extending from the floor ceiling, it is possible to provide a support rail 4 '" projecting only on one side on a vertical wall, in which the projection 13 of the frame 6'"is hooked in the same way it is possible to remove the ceiling element 2 '"from the wall, despite the illumination of the fohe 7""reaching almost to the wall

The invention has been explained in more detail above on the basis of four preferred exemplary embodiments in different construction variants. It goes without saying that the ceiling elements of the various embodiments can also be combined with one another in a common ceiling system. It is further understood that features of one of the ceiling systems presented are those of another ceiling system can be combined within the scope of the present invention, and that a ceiling system or ceiling element formed by such a combination should also be regarded as a further development of the ceiling system according to the invention. It is possible to frame the frame 6 'shown in FIG. 3 with a leg of the type shown in FIG 5 is designated by reference numeral 6 '", whereby a corresponding ceiling is possible by correspondingly connecting adjacent frames 6', in which no support rails 4 are visible any more. It is also possible to cover the ceiling elements with only one foam 7 in in the manner described with a first film 11 for the stated purposes. It is also possible to use the sound insulation means described with reference to the ceiling system 1 ″ for the other ceiling systems provided

The joint 15 is a hinge joint, the legs 17, 18 of which are connected to the frame 6 "" or a connecting profile 19. The right leg 17 is screwed, welded or otherwise connected to the frame 6 ". The left leg 18, on the other hand, has a bar 20 which is arranged perpendicular to the leg 18 and is arranged within a recess 21 of the connecting profile 19. The leg 18 can otherwise be connected to the connecting profile 19 also screwed, welded or otherwise connected

On the space-side downward side of the connecting profiles 19, building boards 22 are attached, which can consist, for example, of plaster or the like and serve to veneer the ceiling 16. On the opposite side, facing the ceiling 16, the connecting profiles 19 are connected to a substructure 22, which For example, can also consist of plasterboard and which is used with its vertically arranged walls 24 in U-shaped grooves 25 of the connecting profiles 19 On the horizontally arranged wall 26 of the substructure 23, three lamps 27 are attached, which space the Fohe 7 " "Illuminate To maintain these lamps 27, the ceiling system 1" "can be opened by opening the ceiling element 2" "so that the light sources 27 become accessible.
