Description

mounting arrangement

The invention relates to a mounting arrangement, in particular a ceiling system, and individual elements of this mounting arrangement.

Mounting arrangements for forming room boundaries, for example ceiling systems for forming suspended ceilings, are known and published in various embodiments.

For example, it is known to suspend a lattice-shaped holding frame from a ceiling, in the frame sections of which individual panels are used. These ceiling systems are usually constructed in such a way that the panels are placed on the holding frame from above and the holding frame is therefore visible from the outside, ie from below in the case of a ceiling. The disadvantage of these systems is that on the one hand the visibility of the frame is sometimes not desired and on the other hand that the panels usually rest unsecured on the frame from above, which means that they can slip out of their position if an object hits them from below. Alternatively, ceiling systems with concealed fasteners are known. With these, assembly is often complicated and labor-intensive. This is particularly the case when the panels are to be precisely aligned with one another. Especially in larger rooms or corridors, even the slightest inaccuracy in the course of the joints provided between the panels is a nuisance.

In conventional systems, there is therefore a conflict of objectives between ease of assembly and the accuracy of the alignment of the plates.

The object of the invention is now to overcome the disadvantages of the prior art and in particular to resolve this conflict of objectives.

The object according to the invention is achieved by the features of the independent patent claims.

The invention relates to a mounting arrangement for forming a room boundary, in particular a ceiling system, comprising a support grid, a plurality of panels, a plurality of connecting devices for the concealed, detachable connection of the panels to the support grid. The support grid preferably includes several support rails.

It is preferably provided that the plates together define a surface and, in particular, form a ceiling when they are attached next to one another on the support grid.

Provision is preferably made for the connecting devices to be designed in such a way that the plates can be connected to and detached from the supporting grid by moving the plates.

It is preferably provided that several fixing parts are provided which, in a fixed position of the assembly arrangement, restrict or fix the movement of the plates in such a way that the plates are exactly aligned with one another along the surface and/or that the connecting device is secured against loosening of the plates. If necessary, it is provided that the fixing parts are each arranged between the plates in the fixed position of the assembly arrangement.

If necessary, it is provided that joints between the panels are kept free and the fixing parts act as spacers in the fixed position of the assembly arrangement and/or comprise a spacer.

If necessary, it is provided that the fixing parts are attached to the support grid in the fixed position of the assembly arrangement, in particular that the fixing parts are attached exclusively to the support grid in the fixed position of the assembly arrangement.

If necessary, provision is made for the connecting devices to be in the form of hook connections from which the panels hang when they are attached to the support grid.

Where appropriate, it is envisaged that the connecting devices are designed in such a way that they can be released by moving the plates against the force of gravity and then transversely to the direction of the force of gravity.

If necessary, provision is made for the fixing parts to prevent movement of the plates transversely to the direction of gravity or along the surface defined by the plates when the mounting arrangement is in the fixed position.

If necessary, it is provided that the fixing parts can be mounted without tools and in particular have a plug-in connection part of a plug-in connection, the plug-in direction of which runs transversely to the surface defined by the plates for mounting.

If necessary, provision is made for a plurality of securing elements to be provided, with the securing elements preventing movement of the plates against the force of gravity and/or transversely to the area defined by the plates when the assembly arrangement is in a secured position. If necessary, it is provided that the securing elements each have at least one securing extension which, in a first orientation, is inserted through the space between the plates, in particular through a joint, and protrudes behind the plate by pivoting into a second orientation in order to move the mounting arrangement into the secured position to move.

If necessary, it is provided that the support grid comprises a plurality of support rails, and that some or all of the support rails are designed as main support rails, on which fastening means for attachment to a surrounding stationary element act.

If necessary, it is provided that the support grid comprises several intermediate rails, which are attached to a surrounding stationary element via the support rails.

If necessary, it is provided that the intermediate rails and the support rails are connected to one another and thereby form a grid whose grid fields essentially correspond to the shapes and sizes of the plate(s) attached to the respective grid fields.

If necessary, it is provided that the panels are each provided with a suspension strip on two opposite outer areas, which in each case forms part of the connecting device.

If necessary, a part of a connecting device, in particular a suspension strip, can also be provided in the central area of the plate. This is particularly the case when this plate extends over several support rails.

If necessary, it is provided that the support frame, in particular the support rails of the support frame, have suspension grooves for suspending the suspension strip.

In particular, the invention relates to a fixing part, set up to form an assembly arrangement according to the invention, comprising a spacer and a plug-in connection part, the spacer being preferably rigid in order to enable exact positioning of the panels relative to one another, and wherein the Plug-in connection part preferably has an elastic section in order to produce a plug-in connection or a clip connection.

In particular, the invention relates to a support rail, set up to form a mounting arrangement according to the invention, comprising a part of the connecting device designed in particular as a hanging groove, a plug-in groove to form a clip connection with the fixing part, a fastening means web for attaching the fastening means, an intermediate rail groove for connection to the intermediate rail.

The support rail preferably has an essentially constant profile cross-section over its course, which optionally includes the following profiles:

- two side-by-side C-shaped profiles open towards the panels, forming the hanging grooves,

- a plug-in groove kept free between the two C-shaped profiles,

- and a cross-shaped profile provided on the back of the C-shaped profile and the plug-in groove, which on the one hand forms the intermediate rail groove on both sides and on the other hand the fastening means web. These profiles are in particular partial profiles of the support rail, which is designed in one piece. Alternatively, these profiles are partial profiles of a multi-part carrier rail, but which are firmly connected to one another.

In particular, the invention relates to a plate for forming a mounting arrangement according to the invention, comprising two hanging rails which are each arranged in an opposite edge region, which run parallel to one another and are aligned in the same way.

The mounting arrangement preferably allows the support frame to be mounted quickly and easily. In particular, even large areas can be mounted very easily and precisely due to the special design of the mounting arrangement. The panels can preferably be mounted from the outside, i.e. from below in the case of the ceiling system design. The assembly is preferably carried out without tools.

The connection of the panels to the support grid is also preferably carried out without tools. In addition, the panels are aligned along the surface, i.e. an alignment of the panels to one another and the setting of precisely running joints, preferably without tools.

Due to the construction according to the invention, the support grid can be formed and installed very easily and efficiently. In particular, mounting rails are mounted to which the panels are attached. The support rails are at least partially in the form of main support rails, which are attached to a surrounding stationary element using fastening means. For example, these fastening means can be hook-shaped, cable-shaped or rod-shaped elements. On the one hand, these are attached to a surrounding stationary element, such as, for example, to the ceiling of the building. On the other hand, they grab the support grid or the main support rails with their other end. Provision is preferably made for the entire support grid to be held by the fastening means only on the main support rails. The remaining support rails and/or the intermediate rails preferably do not have their own attachments, but are supported on the main support rails or are attached to them.

In all of the embodiments, it is preferably provided that the connecting devices are concealed connecting devices that are not visible from the outside, that is to say from the visible side.

It is preferably provided that the plate thickness of the plates of the mounting arrangement can be selected without having to adapt other components of the mounting arrangement for this purpose. In particular, this is possible because the connecting devices are attached to the backs of the panels, so that the thickness extending away from these backs is irrelevant for the assembly capability. In particular, acoustic panels, wood panels, metal panels or other panels be used. In all of the embodiments, it is preferably provided that the plates can be dismantled without tools.

In all of the embodiments, the assembly arrangement is preferably designed as a kit that includes as large a number of identical parts as possible. For example, a large number of identically designed intermediate rails can be included. For example, a large number of identically designed mounting rails can be provided. To vary the length, individual components can be lined up lengthwise using connecting means. If necessary, individual elements can also be cut to length in order to be able to form intermediate lengths or intermediate sizes. All fixing parts of the arrangement are preferably of the same design. If necessary, other fixing parts are used in the edge area of a formed arrangement. In particular, a cross spacer used in the edge area can also comprise only two or three legs. If necessary, a fixing part can also be omitted in the edge area if the panels are fixed using a clip strip.

The invention is further described below with reference to the figures.

Unless otherwise specified, the reference numbers correspond to the following components: Support grid 1, plate 2, connecting device 3, surface 4, fixing part 5, assembly pin 6, joint 7, joint cross 8, plug-in connection part 9, securing element 10, securing extension 11, support rail 12, main support rail 12', edge rail 13, fasteners 14, intermediate rail 15, grid field 16, hanging bar 17, hanging groove 18, clip profile 19, fastening means web 20, plug-in groove 21, intermediate rail groove 22.

1 shows a schematic oblique view of an embodiment of a mounting arrangement. The mounting arrangement is designed as a ceiling system, which is used in particular to form a suspended ceiling.

The arrangement comprises a support grid 1 to which several panels 2 are attached. The support grid 1 comprises a plurality of support rails 12, some of which are designed as main support rails 12'. The main support rails 12' are attached via fastening means 14 to a surrounding building element, not shown, such as, for example, to a soffit. In all of the embodiments, it can preferably be provided that several positions are provided along the support rails 12, in particular along the main support rails 12', at which fastening means 14 can be attached. As a result, the position of the fastening means 14 along the support rails 12 can be selected flexibly. This is particularly necessary when the position of the fasteners 14 is predetermined by the design of the building element. For example, the support rails 12 include a fastening means web 20 that protrudes from the rear and follows the course of the support rail 12, on which several openings or hooks are provided, with which the fastening means 14 can then be connected. In this case, not all possibilities of the fastening means web 20 have to be exhausted, but it is sufficient if the fastening means 14 are connected to those openings or hooks that allow easy assembly.

The support grid 1 comprises a plurality of intermediate rails 15. These intermediate rails 15 preferably each connect two adjacent support rails 12 to one another. By choosing the length of the connecting rails 15, the support grid 1 and in particular the support rails 12 can be precisely aligned with one another. As well An exact alignment of the position of the intermediate rails 15 takes place by selecting the fastening points of the intermediate rails 15 on the support rails 12. The support rails 12 and the intermediate rails 15 preferably have openings through which a mounting pin 6 can be guided if the openings are aligned with one another. The assembly pin 6 and the aligned openings of the intermediate rails 15 and the support rails 12 enable these components to be set up precisely. The support grid 1 is preferably designed in the form of a grid and comprises a plurality of grid fields 16. The grid fields 16 essentially correspond to the shape and possibly also the size of the plate(s) 2 attached in the area of this grid field 16. If necessary, a single plate 2 is arranged per grid field 16. If necessary, several, for example two, plates 2 are arranged per grid field 16 .

Connecting devices 3 are preferably provided, which enable the panels 2 to be mounted on the support grid 1 . In this embodiment, hanging rails 17 are attached to the rear sides of the panels 2, which can be seen in this view. These suspension rails 17 are preferably provided on each panel 2 in the edge area. The plates 2 can be hung on the support grid 1 by means of the hanging rails 17 .

On the other side, pointing downwards in the present illustration, the plates 2 define a surface 4, which is in particular the outside or the visible side of the arrangement.

An edge rail 13 can be provided at the lateral end of the assembly arrangement, in particular at the lateral end of the support grid 1 . This edge rail 13 is optionally designed in such a way that panels 2 can only be mounted on one side via the connecting device 3 .

Fig. 1 shows only a section of a possible assembly arrangement. The assembly arrangement can be continued and enlarged in an analogous manner. Both the size of the grid fields 16 and the overall extent of the arrangement can be flexibly adjusted, in particular enlarged or reduced. The entire mounting arrangement is preferably mounted on a surrounding building element via the main support rails 12 ′ and the fastening means 14 . Further components such as the plates 2, the remaining support rails 12 and/or the intermediate rails 15 are preferably not mounted independently, but are carried by the main support rails 12'.

Fig. 2 shows a schematic oblique view of a plate 2, on the back of which parts of the connecting devices 3 are provided. In particular, the connecting device 3 has a suspension bar 17 . The hanging rails 17 or the parts of the connecting devices 3 are preferably arranged in the edge area of the plate 2 .

The suspension rails 17 are preferably arranged parallel to one another. In particular, the suspension rails 17 are arranged parallel to one another in such a way that their hook-shaped elements also point in the same direction. As a result, the plate 2 can be connected to the support grid 1 by a translatory movement.

The thickness of the plate 2 can preferably be selected variably in all embodiments. However, all plates 2 preferably have the same thickness, so that a smooth surface 4 is formed.

FIG. 3 shows a schematic sectional representation, with the proportions being adjusted so that the individual elements can be represented better.

The assembly arrangement comprises a support grid 1 with a plurality of support rails 12 and a plurality of intermediate rails 15. Those support rails 12 which are attached to a building element, not shown, by means of a fastening means 14 are referred to as main support rails 12'. The entire construction preferably hangs on these main support rails 12'. The support rails 12 are connected to one another via the intermediate rails 15 . In particular, each support rail 12 comprises a region, in particular an intermediate rail groove 22, which is provided for receiving or attaching one end of an intermediate rail 15. In this area, the Intermediate rail 15 and the support rail 12 in the mounted position each have openings which are aligned with one another in such a way that a mounting pin 6 can be passed through. The mounting rails 12 are connected to the intermediate rails 15 by the mounting pins 6 .

It is preferably provided in all of the embodiments that the openings for passing through the mounting pins 6 in the support rails 12 are arranged along the support rails 12 at a predetermined spacing or pattern. By simply choosing one of these openings, a regular or desired pattern of the support grid 1 or the grid can be formed.

The plates 2 are connected to the support grid 1 via connecting devices 3 . In the present embodiment, two suspension rails 17 are provided for each panel 2 . These suspension rails 17 of a panel 2 preferably run parallel and aligned in the same way. By moving in the direction of the support grid 1 and then moving along the surface 4 , the suspension rails 17 can be hung in suspension grooves 18 of the support grid 1 , in particular the support rails 12 . Plate 2 must then be slightly lowered again to hang it up.

In order to prevent the connecting devices 3 from being accidentally released simply by lifting the panel 2, a plurality of fixing parts 5 are provided according to the invention. These fixing parts 5 restrict the possibilities of movement of the plates 2 in such a way that the connecting device 3 cannot be detached. In the present case, a plate 2 can still be moved translationally upwards or in the direction of the support grid 1, but lateral movement along the surface 4, which would be necessary to release the connecting device 3, is blocked by the fixing parts 5. In addition, the fixing parts 5 serve as a stop or as a spacer 8 for the panels 2, so that the panels 2 are precisely aligned with one another along the surface 4. In particular, joints 7 are kept free between the plates 2, in which the fixing parts 5 or their section designed as a spacer 8 are or is arranged. To fasten the plates 2 , they are hooked into the support grid 1 in the form of a hook via the connecting device 3 . If the plates 2 are pre-assembled in this way, the fixing parts 5 can be assembled, which on the one hand lock the connecting devices 3 against loosening and on the other hand align the plates 2 with respect to one another. For this purpose, the fixing parts 5 preferably have a plug-in connection part 9 which is inserted into a plug-in groove 21 in order to produce a plug-in connection. The plug-in groove 21 preferably has an undercut or groove so that the plug-in connection part 9 can act as a clip. The plug-in groove 21 preferably follows the course of the support rails 12. The plug-in grooves 21 are preferably arranged centrally along the support rails 12.

FIG. 4 shows a detailed representation of this connection, in particular the connection according to one or more of the other figures. The plates 2 are connected via the connecting device 3 or via a hanging groove 18 and a hanging bar

17 connected to the support grid 1 or its support rail 12. This pre-assembly is done by hanging the panels 2 in the support grid 1 .

The connection devices 3 are in turn fixed by means of fixing parts 5. In this embodiment, these fixing parts 5 each comprise a plug-in connection part 9 and a spacer 8.

The support rail 12, which can be embodied in particular as a main support rail 12', preferably comprises the following components in all embodiments: Part of a connecting device 3, in particular a hanging groove 18. If necessary, at least one hanging groove 18 is provided on both sides of the longitudinal center plane of the supporting rail 12. If necessary, two hanging grooves 18 are provided on each side of the longitudinal center plane of the support rail 12, so that four hanging grooves

18 are provided on a mounting rail 12. These hanging grooves 18 each extend on both sides of a slot-shaped opening through which the hanging rail 17 of the plate 2 can be inserted. The two hanging grooves 18 on one side of the support rail 12 are preferably mirrored or aligned in opposite directions, so that a hanging rail 17 can be hung in one direction or the other, depending on the orientation. In addition, the support rail 12 includes an insertion groove 21 which is preferably arranged between those sections which form the hanging grooves 18 . The plug-in groove 21 preferably follows the longitudinal course of the support rail 12. In particular, it is arranged centrally along the longitudinal central axis of the support rail 12. The support rail 12 is preferably symmetrical transversely to the longitudinal center plane, so that the plug-in groove 21 runs centrally and the hanging grooves 18 are arranged symmetrically thereto.

In addition, the support rail 12 preferably includes a fastening means web 20 which is arranged in particular on the opposite side of the hanging grooves 18 . The fastener web 20 is preferably arranged centrally and thus runs essentially centrally along the longitudinal center plane of the support rail 12. The fastener web 20 preferably has a plurality of openings or hooks for attaching the fasteners 14.

The carrier rail 12 preferably has at least one intermediate rail groove 22 which is designed to be connected to the intermediate rail 15 . In particular, the intermediate rail 15 can be inserted into the intermediate rail groove 22 in order to hold the intermediate rail 15 on the support rail 12 . In addition, both the intermediate rail 15 and the intermediate rail groove 22 or their delimiting elements can have openings. If the openings in the intermediate rail 15 are aligned with the openings in the mounting rail 12 , mounting pins 6 can be passed through in order to establish a connection between the mounting rail 12 and the intermediate rail 15 . Two openings are preferably provided for each intermediate rail 15 along the longitudinal extent of the support rail 12 . As a result, pivoting of the intermediate rail 15 relative to the support rail 12 can be prevented. In principle, however, any type of connection can be used in order to connect the support rail 12 and the intermediate rail 15 to one another in the correct position. In the present embodiment, the profile cross section of the support rail 12 thus comprises two C-shaped profiles which are open next to one another in the direction of the plates 2 and which form the hanging grooves 18 . An insertion groove 21 is kept free between these two C-shaped profiles. At the back of the C-shaped profiles and the plug-in groove 21 is a cross-shaped profile is provided, which on the one hand forms the intermediate rail groove 22 on both sides and on the other hand the fastening means web 20 .

5 shows a possible embodiment of a fixing part 5. In all embodiments, this preferably comprises a plug-in connection part 9 and a spacer 8. The spacer 8 is preferably rigid in order to enable exact positioning of the panels 2 relative to one another. The plug-in connection part 9 preferably has an elastic section in order to be able to produce a plug-in connection or a clip connection. In the present embodiment, the plug connection part 9 has two elastically deformable wings protruding from the spacer 8 along two legs of the spacer 8 . These two wings can be pressed towards one another in order to produce a plug-in connection, in particular with the plug-in groove 21 . By overcoming a certain holding force, the fixing part 5 can be removed easily and preferably without tools. In all of the embodiments, the fixing part is preferably held in the plug-in groove 21 only in a non-positive manner. The fixing part 5 is preferably a plastic part, for example an injection molded part. The fixing part 5 is preferably a one-piece plastic part, with a substantially rigid spacer 8 and an elastically deformable plug connection part 9 being formed by the selection of the thickness of the individual elements.

6 shows a possible embodiment of a securing element 10. This securing element 10 has at least one securing extension 11, with two securing extensions 11 being provided in this embodiment, which project transversely from a central body in the shape of wings. In addition, the securing element 10 optionally has an element for a twisting tool such as a screwdriver. This element allows the securing element 10 to be easily twisted with a tool.

FIG. 7 shows a schematic sectional view of an assembly arrangement in which a securing element 10 is used. In particular, FIG. 7 shows a mounting arrangement in a secured position. In principle, the connection of the plate 2 to the support rail 12 corresponds to that from FIG. 4 and/or FIG. 3. However, a securing element 10 is additionally used to secure the connecting device 3. during that Fixing part 5 preferably prevents displacement of the plates 2 along the surface 4, the securing element 10 can be used to prevent the plates 2 from moving in the direction of the support grid 1 or transversely to the surface 4. For this purpose, the securing element 10 can be inserted into the plug-in groove 21 with its central body, optionally through a gap 7 . Subsequently, the securing element 10 can be twisted in such a way that its securing extension 11 protrudes between the plate 2 and the mounting rail 12 and/or that the securing extension 11 protrudes between the hanging groove 18 and the plate 2 . In order to release the plate 2 and in particular the connecting device 3, the securing element 10 must be twisted again in such a way that the securing extension 11 allows the plate 2 to move in the direction of the support grid 1 and no longer blocks it. Once this has happened, the plate 2 can be moved in the direction of the support grid 1, with which the suspension rail 17 is moved out of the suspension groove 18. By moving the plate 2 along the surface 4, the suspension rail 17 can then be moved in a region of the support rail 12 by being moved away from the support grid 1 and being pulled out of the support rail 12.

In the representation of FIG. 7, a plate 2 is attached to the support rail 12 on only one side. On the other side of the longitudinal center plane of the support rail 12 a clip profile 19 is attached to the support rail 12 . This clip profile 19 is used in particular when the support rail 12 forms the lateral end of the assembly arrangement. The position of the plate 2 is fixed in this area by the clip profile 19. A fixing part 5 can be omitted in this area. In addition, the clip profile 19 preferably also closes the openings of those suspension grooves 18 that are not required in this area.

In all of the embodiments, the support rail 12 is preferably formed from a one-piece profile. In particular, the profile is a metal profile such as an aluminum profile. The support rail 12 preferably has a constant profile or a constant cross section over its entire course. If necessary, openings are provided in the support rail 12 which, for example, allow a connection to the intermediate rail 15 . In the following, exemplary steps for forming an arrangement according to the invention, in particular according to at least one of the figures, are described:

This method is described using a suspended ceiling.

The starting point for assembly is a first mounting rail 12, which is designed as a main mounting rail 12'. This is attached to a surrounding building element, e.g. Depending on the type of raw ceiling, anchoring is preferably carried out with fastening elements approved by the building authorities. Each main support rail 12' is mounted at a predetermined distance from the next main support rail 12'. The distance can be between 1 and 2 m, for example, preferably 1210 mm. The distance between the main support rails 12' is preferably predefined. The support rails 12 and in particular the main support rails 12' are preferably provided with all the necessary bores or millings.

If smaller panels 2 are to be used than the distance between the main support rails 12', further support rails 12 can be arranged between the mounted main support rails 12', but these do not have to be attached to the shell ceiling with a fastener.

After the first two main support rails 12' have been attached, at least one intermediate rail 15 is mounted. The first two intermediate rails 15 are preferably installed. The intermediate rails 15 are fastened to the main support rails 12' with mounting pins 6. In particular, the ends of the intermediate rails 15 are inserted into the intermediate rail grooves 22 of the support rails 12 or the main support rails 12'. If necessary, the intermediate rails 15 can be pushed to the predetermined location at the ends of the support rails 12 that have already been installed along the intermediate rail grooves 22 . At this point they are then fastened with mounting pins 6. The intermediate rails 15 are ready for assembly and are preferably provided with all the holes required for the connection are necessary. The intermediate rails 15 are preferably of a length which causes the mounting rails 12 to be spaced exactly to the desired extent.

By connecting a plurality of intermediate rails 15 to a plurality of support rails 12 or main support rails 12', an exact alignment of the grid of the support grid 1 is brought about. The connection of the support rails 12 with the intermediate rails 15 is preferably carried out without tools, in particular by the mounting pins 6, which are inserted into prefabricated openings.

In the edge area, an edge rail 13 can be slid on and fastened parallel to the intermediate rails 15 . The edge rail 13 can also be fastened using the same mounting pins 6 . In particular, the edge rail 13 can be slid onto the intermediate rail 15 in parallel. The assembly pins 6 preferably connect all parts to one another. The mounting pins 6 are preferably always pressed from top to bottom into the openings provided for this purpose. The mounting pins 6 can be removed again if necessary.

A clip profile 19 can be pressed in before or during assembly of the panels 2. This clip profile 19 can form a conclusion and a stop for the panels 2. The clip profile 19 can either be offset at the corners or mitred. Such a clip profile 19 can optionally also be omitted.

If the support grid 1 is of sufficient size, the panels 2 can be connected to the support grid 1 .

Two suspension rails 17 are preferably provided on the backs of the panels 2 . These suspension rails 17 of a panel 2 preferably run parallel to one another and are aligned in the same direction. The hanging rails 17 are preferably arranged in opposite edge regions of the panels 2 . The suspension rails 17 can be glued to the panels 2 or screwed. The panels 2 can, for example, also be other elements such as lamps, grids, acoustic panels or the like. Subsequently, the panels 2 are connected to the support grid 1 via the connecting devices 3 . In particular, the connecting devices 3 comprise suspension grooves 18 provided on the support rails 12, into which suspension rails 17 of the panels 2 can be inserted. For this purpose, the plate 2 is moved in the direction of the support grid 1 and then along the surface 4 in order to hang the suspension rails 17 in the suspension grooves 18 .

The fixing parts 5 are then used to center the position and to fix it against lateral movement and to prevent movement along the surface 4 . The fixing parts 5 are pressed in particular into the gaps 7 kept free between the panels 2 . The fixing parts 5 preferably act as spacers 8, which bring about an exact alignment of the panels 2 with respect to one another. However, this orientation also prevents the connecting device 3 from becoming detached.

To connect the fixing part 5 to the mounting rail 12, the fixing part 5 includes a plug-in connection part 9, which can be pressed or clipped into a plug-in groove 21 of the mounting rail 12. This assembly can also be done without tools. The fixing parts 5 can also preferably be removed without tools.

For additional security, the plates 2 can optionally be fixed further. This can take place through the securing element 10 . The securing element 10 can be inserted through a joint 7 and twisted, so that movement of the panels 2 in the direction of the support grid 1 is also prevented.
