Description

The invention relates to a carrier system.

Carrier systems consisting of carriers and connecting elements connecting the carriers are used, for example, for so-called grid element ceilings, ie suspended interior ceilings. Such grid element ceilings are used, for example, to lay temporary attachment points for event technology and supply lines such as power lines to desired locations in exhibition halls and/or to create attachment options for attachments at desired positions on the suspended interior ceiling.

From the DE 20 2006 002 567 U1 a suspended, non-load-bearing interior ceiling made of longitudinal members and cross members connecting the longitudinal members is known. The side members and cross members are designed as extruded profiles. There are grooves for side adapters in the side rails. A crossbeam with a front plate arranged on the front side of the crossbeam can be hooked into the side adapter. To connect longitudinal members to one another, a connecting profile is provided which protrudes into the hollow chambers of the longitudinal members to be connected to one another.

The DE 34 43 883 A1 discloses a structural lattice whose polygonal profile rods carry profile inserts at their front ends. The profile inserts are hung on rail sections that serve as grid nodes.

The DE 10 2006 027 804 B3 discloses a grid ceiling made of sheet metal cuts that can be plugged into one another.

The object of the invention is to provide a carrier system of the generic type which has a simple structure and enables the carrier system to be assembled quickly and flexibly.

This object is achieved by a carrier system having the features of claim 1.

Provision is made for the carriers to be connected to one another via plug-in connections. Provision is made for each connecting element to have at least one plug-in connection component of a plug-in connection. The carrier system has first connecting elements, the at least one plug connection component of which is arranged on a longitudinal side of the associated carrier. In order to achieve a simple and modular construction of the carrier system, it is provided that the carrier system comprises second connection elements, the at least one plug-in connection component of which is arranged on an end face of the associated carrier. The second connecting elements are designed in such a way that they can be selectively connected to a first connecting element or to a further second connecting element. As a result, a beam that carries a second connecting element on one end face can optionally be attached as a crossbeam and connected to a first connecting element of an existing longitudinal beam for this purpose, or alternatively used as a longitudinal beam and connected to a second connecting element arranged on the end face of another longitudinal beam for this purpose . This achieves a simple construction of the carrier system. The number of required different types of fasteners is reduced because of second fasteners both Longitudinal members and cross members can be connected to existing longitudinal members. This also simplifies warehousing and logistics. Cross members and longitudinal members can be designed with the same dimensions and in particular also have the same cross-sectional structure. This simplifies production and storage. The appearance of the carrier system is attractive, since there is no visual distinction between the longitudinal carriers and the transverse carriers when the carrier system is installed.

Because the carriers are connected to one another via plug-in connections, the carrier system can be assembled and disassembled quickly and easily. Preferably, no screw connections are to be fixed or loosened to connect the supports. A plug-in connection enables the beams to be connected to one another with a non-positive fit and can also transmit transverse forces and moments between the beams. This achieves a simple and firm connection of the carriers to one another. The plug connections can be arranged in a space-saving manner. Plug-in connections enable a largely invisible connection of the carriers, so that the use of plug-in connections results in an attractive appearance of the carrier system.

In a preferred embodiment, all of the carriers are provided with second connecting elements on their end faces. Each second connecting element preferably has both a plug-in element and a plug-in receptacle of the plug-in connection. As a result, only a single version of the second connection element is required. Plug-in receptacle and plug-in element are preferably arranged one above the other in the installed position. In the case of longitudinal members running in the longitudinal direction, the plug-in element and the plug-in receptacle are preferably oriented differently on the two end faces of the longitudinal member. The plug-in element is arranged on one end in the upper area and the plug-in receptacle in the lower area of the connecting element, and on the other end the plug-in receptacle is arranged in the upper area and the plug-in element in the lower area of the connecting element. This can easily be done by installing the second connecting element can be achieved in an orientation rotated by 180° about the longitudinal axis of the carrier. As a result, a further longitudinal member can always be installed in the same direction, preferably from above, on an already installed longitudinal member. In the case of cross members, a second connecting element is preferably arranged on both end faces in the same orientation, preferably with the plug-in receptacle in the lower area and the plug-in element in the upper area. As a result, cross members can be mounted on both end faces simultaneously in adjacent longitudinal members in the same orientation, ie in particular from above.

The designations "top", "bottom", "horizontal" and "vertical" and all other terms relating to the spatial position that are used here relate to the installation position of the carrier system in which the carrier system is arranged on a carrier structure.

The plug-in receptacles are preferably oriented in the vertical direction to enable assembly from above. In an alternative design, however, it can also be provided that the plug-in receptacles run laterally to the longitudinal direction of the carrier and a carrier can thus be mounted on an existing carrier in the lateral direction, for example by pivoting in or sliding laterally.

Each connecting element advantageously has at least one plug-in element and at least one plug-in receptacle. As a result, each connecting element can form each plug-in connection component of a plug-in connection, namely plug-in socket or plug-in element. In a particularly preferred embodiment, in the case of two connecting elements connected to one another, each plug-in element is arranged in an associated plug-in receptacle. As a result, a high strength of the plug-in connection is achieved at the same time and the orientation of the carriers to one another can be fixed via the two plug-in elements spaced apart from one another in the connection plane. As a result, comparatively high moments about the longitudinal axis of a beam can also be absorbed. However, it can also be provided that each connecting element Although each has a plug-in element and a plug-in receptacle, however, in each plug-in connection, either the plug-in element or the plug-in receptacle is alternatively on an associated plug-in connection component of the other connecting element.

In a particularly preferred embodiment, the plug-in element is formed by a screw. An element that engages behind the plug-in receptacle can be provided in a simple manner by means of a screw. By changing the screw-in depth of the screw, the relative position of the carrier to each other can be changed. As a result, existing positional tolerances between the carriers can be compensated for in a simple manner.

In a particularly preferred embodiment, the plug-in receptacle is designed as a recess. This results in a simple structure.

In order to prevent the plug-in connection from being released when forces occur counter to the assembly direction, at least one plug-in securing element is advantageously provided, which secures the plug-in connection against unintentional release. Due to the fact that the fuse element can be plugged in, no screw connection is required to secure the plug-in connection, resulting in simple and quick assembly and disassembly. If the plug-in receptacles are oriented in the vertical direction in the installed position, the securing element is a cotter pin in a preferred embodiment. In the case of a horizontally oriented plug-in receptacle, the securing element can be, for example, a U-shaped disk or the like that is to be inserted from above.

The carrier system advantageously comprises at least one suspension element which is separate from the connecting elements and is provided for connecting a carrier to a supporting structure. The suspension element can, for example, be fixed to the ceiling of the room in a known manner using threaded rods. Because the suspension element is designed separately from the connecting elements, the position of one or more suspension points can be selected independently of the position of the cross member. It is advantageously provided that at least one connecting element itself Connection of a carrier is provided with a supporting structure. As a result, the number of parts required for connecting the carriers to one another and connecting them to the supporting structure can be reduced. A connecting element which is provided for connecting a carrier to the support structure and at the same time serves to connect two carriers to one another is particularly advantageous when the connection points on the support structure coincide with the connection points of longitudinal members and cross members.

A simple structure is obtained when at least one connecting element has a connecting clip that encompasses the associated carrier. In a particularly advantageous embodiment, the connecting bracket is designed to be closed and completely encloses the carrier. However, a partially open shape of a connecting clip can also be advantageous, in particular a shape that is open at the bottom. As a result, in particular a mounting rail running on the underside of a carrier can also remain accessible in the area of the connecting bracket.

In a preferred embodiment, the connecting bracket is formed by two individual parts connected to one another on the upper side and the lower side of the carrier. The two individual parts are preferably C-shaped. Because the individual parts are connected to one another on the top and bottom of the carrier, no connecting elements are required on the long sides of the carrier, resulting in an attractive appearance of the carrier system. The individual parts are preferably connected to one another via at least one detachable connecting device. As a result, a connecting bracket can also be retrofitted to a longitudinal member that is already mounted on a supporting structure. At the same time, the plug-in connection between a longitudinal member and a cross member is not affected by the connecting device that connects the individual parts of the connecting bracket to one another. The two individual parts are C-shaped in a preferred design and overlap adjacent to the top and bottom of a carrier.

In a particularly preferred embodiment, the individual parts are connected to one another via at least one connecting device, which at the same time fixes the connecting element to the carrier. As a result, the number of individual parts required for the carrier system can be reduced. The connecting device preferably comprises a connecting element which protrudes through openings in both individual parts, so that the individual parts are connected to one another even when the connecting device is partially released and the connecting element cannot become detached from the carrier. The connecting element can be a hammer head screw, for example. In an advantageous embodiment, the individual parts are connected to one another via at least one connecting device, which is also used to connect the connecting element to the support structure. As a result, no additional elements are required for connection to the supporting structure. In a preferred embodiment, the individual parts are connected to one another on their underside via a connecting device, which at the same time fixes the connecting element to the carrier. Alternatively, a connecting device can be provided on the upper side of the carrier, which fixes the connecting element to the carrier, or a connecting device, which is used to connect the connecting element to the supporting structure.

At least one connecting element, in particular a second connecting element, preferably has at least one tab for insertion into a carrier at the front. As a result, the connecting element can be mounted in a simple manner on the face side of a carrier.

At least one connecting element is preferably designed largely as a bent sheet metal part. In a particularly preferred embodiment, all connecting elements are largely designed as bent sheet metal parts. Only the plug-in elements, preferably screws, and elements of the connecting device are preferably arranged on the bent sheet metal parts.

In a preferred embodiment, it is provided that each plug-in connection is to be mounted from above in the installation position and produces a firm connection in all horizontal directions and a firm connection downwards. Since the plug-in connection can be fitted from above in the installation position and creates a firm connection in all horizontal directions downwards, the plug-in connection can be fitted by one person. After the plug-in connection has been made, the two carriers are firmly connected to one another. The safety element that may have to be additionally installed is only used to secure the connection. Due to the fact that no screw connections have to be made, a very short assembly time is achieved.

For a non-claimed system of connecting elements for connecting carriers by means of plug-in connections, each connecting element having at least one plug-in connection component of a plug-in connection, the interacting plug-in connection components forming the plug-in connection comprising at least one plug-in element and at least one plug-in receptacle, it is provided that the first connecting elements have a receptacle for carrying out a carrier, wherein the at least one plug-in connection component of the first connection elements is arranged laterally to the longitudinal direction of the receptacle. The system also includes second fasteners having at least one tab for attaching the fastener to the face of a wearer. The second connecting elements have at least one plug-in connection component, which is arranged on the side of the connecting element facing away from the tab. The second connecting elements are designed in such a way that they can be selectively connected to a first connecting element or to a further second connecting element.

1 shows a perspective view of an embodiment of a carrier system, namely a grid element ceiling 1. The grid element ceiling 1 is made up of longitudinal beams 2, which run parallel to one another. The longitudinal beams 2 are to be connected to a supporting structure, for example a hall ceiling, via connecting elements, in the exemplary embodiment threaded rods 11 . The side members 2 are connected to one another via cross members 3, which run at right angles to the side members 2 in the exemplary embodiment. The longitudinal members 2 and cross members 3 span a grid-like grid. In the exemplary embodiment, for connecting the threaded rods 11 to a support structure, the upper end of the threaded rods 11 facing away from the grid element ceiling 1 is provided with holding parts 12, which can be screwed to the support structure. The threaded rods 11 are adjustable both in relation to the holding parts 12 and in relation to the grid element ceiling 1, so that the grid element ceiling 1 is adjustable in terms of its height.

The longitudinal members 2 and cross members 3 are connected to one another via plug connections 4 . 2 shows a connector 4 between two side members 2 in an enlarged view. Each longitudinal member 2 carries at its transverse to a longitudinal center axis 31 ( 3 ) of the longitudinal member 2 lying end face 16 a connecting element 8. The connecting elements 8 have how 3 shows, in each case a plug-in element 5 and a plug-in receptacle 6 . In the exemplary embodiment, the plug-in receptacle 6 is oriented in the vertical direction and has an access opening on its side facing away from the plug-in element 5 . 3 shows the mounted on a supporting structure, in 2 Longitudinal member 2 shown on the left. On this longitudinal member 2, the in 2 Longitudinal members 2 shown on the right are fixed when the second connecting element 8 is attached to the in 2 the longitudinal member 2 shown on the right is reversed, ie rotated by 180° about the longitudinal center axis 31 of the longitudinal member 2 relative to the second connecting element 8 of the left longitudinal member 2 .

In order to prevent the plug connection 4 from being released unintentionally, for example due to a load on the in 2 longitudinal member 2 shown on the right upwards, a cotter pin 14 is provided, which is inserted transversely through a connecting element 8 in the area of the insertion opening of the plug-in receptacle 6 . This prevents a plug-in element 5 arranged in the plug-in receptacle 6 from being able to escape from the plug-in receptacle 6 .

In 2 a first connecting element 7 is also shown, which is used both for connecting to a support structure and for connecting cross members 3 ( 1 ) serves. How 2 shows, the threaded rod 11 protrudes through the top of the first connecting element 7. The top of the connecting element 7 is the side which is arranged adjacent to a top 17 of the longitudinal beam 2. The upper side 17 is the side of the longitudinal member 2 arranged at the top in the installed position. Nuts 13 for fixing the connecting element 7 to the threaded rod 11 are screwed onto the threaded rod 11 above and below the connecting element 7 . The vertical position of the connecting element 7 relative to the threaded rod 11 can be changed by turning the nuts 13 . How 2 also shows, the first connecting element 7 also has plug-in receptacles 6, which are each arranged on a longitudinal side 15 of the longitudinal member 2. In the plug-in receptacles 6 of the first connecting element 7, cross members 3 can be plugged in with their frontally arranged second connecting elements 8, such as 3 shows. The second connecting elements 8 are connecting elements which are used to connect side members 2 to one another or to connect them to a first connecting element 7 of a side member 2 . How 2 also shows, the threaded rods 11 are fixed to the connecting elements 7.

4 shows an embodiment of a grid element ceiling 1 made of longitudinal beams 2, which are connected via the cross beams 3. Plug connections 4 for connecting the cross member 3 to the longitudinal members 2 are also provided here. However, the crossbeams 3 are fixed to connecting elements 9 that do not have a connection for threaded rods 11 exhibit. This is in the Figures 5 and 6 shown. When executing after the Figures 4 to 6 separate suspension elements 10 are provided instead, on which the threaded rods 11 are fixed. For connection to the first connecting element 9 , the cross member 3 has a second connecting element 8 on its end face 16 . The connecting elements 9 and 8 form the plug-in connection 4 with their plug-in receptacles 6 and plug-in elements 5. In the connected state, each plug-in element 5 is arranged in an associated plug-in receptacle 6 of the respective other connecting element 8, 9.

Both the connecting elements 7 and 9 and the suspension elements 10 are bow-shaped and completely enclose the respective longitudinal member 2 . How figure 5 shows, the connecting elements 9 are also first connecting elements, in which the plug-in element 5 and the plug-in socket 6 are arranged on a longitudinal side 15 of the associated longitudinal beam 2 .

The Figures 7 to 11 show a cross member 3 in detail. The crossbeam 3 has an upper side 17, an opposite underside 18, which points downwards in the installed state, and two end faces 16. In the exemplary embodiment, the crossbeam 3 is cuboid. The end faces 16 are the smallest sides of the cuboid, and the long sides 15 ( 8 ) are the largest sides of the cuboid.

How 7 shows, a first connecting element 8 is arranged on each end face 16 . In the exemplary embodiment, the plug-in elements 5 are arranged on both end faces 16 adjacent to the upper side 17 of the cross member 3 . It is preferably provided for longitudinal members 2 that on one end face 16 the plug-in element 5 is arranged adjacent to the upper side 17 and on the other, opposite end face 16 the plug-in element 5 is arranged adjacent to the underside 8 . A longitudinal member 8 is preferably mounted on a support structure in such a way that the plug-in element 5 is arranged adjacent to the underside 18 on the end face 16 on which a further longitudinal member 2 is to be mounted. As a result, the following longitudinal beam 2 can be connected to the end face 16 on which the plug-in element 5 is arranged adjacent to the top 17, are attached to the existing longitudinal member 2.

8 shows a view of the top 17 of the cross member 3. How 8 shows, a longitudinal slot 26 runs on the upper side 17 over the entire length of the cross member 3 between the connecting elements 8. The longitudinal slot 26 is also in 9 shown. How 9 also shows, the plug-in element 5 is formed by a screw screwed into a bent sheet metal part of the connecting element 8 . When connected to a plug-in receptacle 6 , the head 32 of the screw engages behind the walls delimiting the plug-in receptacle 6 and thus creates a non-positive connection between two adjacent second connecting elements 8 or a connection to a connecting element 7 or 9 . How 9 also shows, the second connecting element 8 has an opening 27 for the safety cotter pin 14 ( 2 ). How 11 shows, two opposing openings 27 are provided, so that the safety pin 14 can be fully inserted through the second connecting element 8.

As the Figures 9 to 11 show, the cross member 3 is made up of two mounting rails 29 which run on the upper side 17 and the lower side 18 . The mounting rails 29 each form the longitudinal slot 26. The longitudinal slot 26 is delimited by rail lips 41 of the mounting rails 29 that project towards one another. The two mounting rails 29 are connected via side walls 30 ( 11 ) connected, which form the longitudinal sides 15 of the cross member 3. A second connecting element 8 is inserted in each case on the end faces 16 of the cross member 3 . For this purpose, the connecting element 8 has two lugs 21 which extend between the backs of the two mounting rails 26 of the cross member 3 .

The second connecting element 8 is like that Figures 9 to 11 show designed as a U-shaped bent sheet metal part. The bottom of the U runs parallel to the end face 16 of the cross member 3 and has the plug-in receptacle 6. The das Plug-in element 5 arranged forming screw, which is screwed into a nut 28 held on the bent sheet metal part in the embodiment. By changing the screwing depth of the plug-in element 5, an adjustment of the cross member 3 relative to a longitudinal member 2 or an adjustment of two longitudinal members 2 connected to one another is possible.

The mounting rails 29 are used both for fixing the first connecting elements 7, 9 and suspension elements 10 on the cross member 3 and for fixing add-on parts to the cross members 3 or longitudinal members 2. The longitudinal members 2 are - except for the arrangement of one of the two connecting elements 8 - constructed identically to the crossbeams 3.

The Figures 12 to 15 show a first connecting element 7 in detail. How 12 shows, the connecting element 7 is made up of a connecting bracket 22 into which the plug-in elements 5 are screwed. A connecting device 34 is also arranged on the bottom 43 of the connecting bracket 22 . The connecting bracket 22 has two opposing plug-in receptacles 6 and plug-in elements 5. An opening 33 is provided on the upper side 44 of the connecting bracket 22 opposite the base 43, which is used to receive the threaded rod 11 or another holding element for connection to a supporting structure. How 12 and 14 show, the connecting bracket 22 is formed by two individual parts 25, both of which are designed approximately C-shaped and parallel to the longitudinal side 15 ( 8 ) running central part 45 and parallel to the upper side 17 and lower side 18 ( 7 ) extending end portions 46, 47 have. The end sections 46 and 47 of the two individual parts 25 are in contact with one another. One of the individual parts 25 preferably encompasses the other of the individual parts 25, so that the two individual parts 25 are also pre-fixed when the connecting device 34 is released.

How 13 shows, an insertion bevel 39 is provided on the plug-in receptacle 6, which facilitates the insertion of the plug-in element 5 into the plug-in receptacle 6. In the area of the plug-in receptacle 6, the connecting bracket 22 is widened. In the widened Area two lateral holes 48 are arranged. The first connecting element 7 can be fixed to a side member 2 through the lateral bores 48, for example using self-tapping screws. This achieves a torsion-resistant mounting for a cross member 3 suspended on the connecting element 7 . Twisting of the cross member 3 about its longitudinal center axis 31 is prevented by this additional fixation of the connecting element 7 on the longitudinal member 2 .

The connecting device 34 has such 13 shows a screw 36, which is designed as a hammer head screw in the exemplary embodiment, and a nut 38 screwed onto the screw 36. The screw 36 protrudes through bores 49 in the two end sections 47 of the individual parts 25. By turning the screw 36 by 90° around its longitudinal center axis the hammer head 37 can be arranged in such a way that it engages behind the slot 35. The connecting device 34 can be fixed by tightening the nut 38 . As the 13 and 14 show, a distance a is formed between the hammer head 37 and the connecting bracket 22 . The distance a corresponds approximately to the thickness of the rail lips 41 ( 11 ) of the mounting rails 29. The screw 36 serves not only to fix the two individual parts 25 to one another, but also to fix the first connecting element 7 to a longitudinal member 2 or cross member 3. For this purpose, the connecting element 7 is attached to the desired location of the longitudinal member 2 or cross member 3 positioned, the hammer head 37 inserted through the longitudinal slot 26 into the mounting rail 29 and fixed by turning in the mounting rail 29 and then the nut 38 fixed on the screw 36. How 14 and 15 show, the plug-in elements 5 are screwed into threaded holes 42 of the individual parts 25 . An additional mother for the plug-in elements 5 can be omitted. Also with the second connecting element 8, instead of the nut 28 ( 10 ) A threaded hole for the plug-in element 5 can be provided in the connecting element 8 itself.

The connecting element 7 has how 14 shows a receptacle 19 in which a longitudinal member 2 or cross member 3 can be arranged. The longitudinal central axis 31 of the carrier 2, 3 is then arranged parallel to the longitudinal direction 20 of the receptacle 19. at in of the receptacle 19 arranged carrier 2, 3, the plug element 5 and the plug receptacle 6 are arranged on a longitudinal side 15 of the carrier 2, 3.

The Figures 16 to 19 show a suspension element 10. The suspension element 10 has a connecting bracket 24 which is made up of two individual parts 25. FIG. The suspension element 10 does not have any plug-in elements 5 or plug-in receptacles 6, but only an opening 33 for receiving a threaded rod 11. The opening 33 protrudes through the end sections 46 of the individual parts 25 and, when installed, is arranged adjacent to the upper side 17 of a longitudinal member 2 or cross member 3 (see Fig . 7 ). Adjacent to the underside 18 of a side member 2 or cross member 3 is the connecting device 34 which is used at the same time to fix the suspension element 10 to the side member 2 or cross member 3 . The screw 36 protrudes through bores 49 in the two individual parts 25. The suspension element 10 also has a receptacle 19 in which the longitudinal beam 2 or cross beam 3 can be arranged. The longitudinal central axis 31 of the carrier 2, 3 is then arranged parallel, in particular congruently, to the longitudinal direction 20 of the receptacle 19.

The Figures 20 to 23 show a first connecting element 9. How 20 shows, the first connecting element 9 is formed by a connecting bracket 23, which is made up of two individual parts 25. The first connecting element 9 differs from that in FIGS Figures 12 to 15 shown first connecting element 7 characterized in that the first connecting element 9 has no opening 33 for connection to a threaded rod 11. Instead, in the area that is adjacent to an upper side 17 ( 7 ) of a longitudinal member 2 or cross member 3 is arranged, ie at the end portions 46 of the individual parts 25, a connecting device 34 with a screw 36 is provided. The connecting devices 34 on the top 17 and the bottom 18 of the carrier 2, 3 are preferably of identical design. How 20 and 23 show, the individual parts 25 on the connecting device 34 have a slot 35 on the end sections 46 through which a hammer head 37 ( 13 and 14 ) of screw 36 is inserted. This allows the screw 36 from the outside through the Slot 35 are mounted on the connecting element 9. On the other hand, bores 48 are provided on the end sections 47, through which the screw 36 is to be fitted from the inside. In alternative configurations, the slot 35 may be provided on the end portions 47 or on both the end portions 46 and the end portions 47.

In alternative configurations, the connecting elements 7 can also have slots 35 on the end sections 47 instead of bores 48 . Alternatively or additionally, the suspension elements 10 can have slots 35 on the end sections 46 and/or on the end sections 47 instead of bores 48 .

As the 20 and 21 show, the screw 36 has a marking 40 at the free end of its threaded section. The correct seating of the screw 36 can be checked via the marking 40 after assembly. If the hammer head 37 is correctly aligned perpendicular to the longitudinal direction of the longitudinal slot 26, the marking 40 also runs perpendicular to the longitudinal slot 26.

In the exemplary embodiment, all plug-in receptacles 6 run in the vertical direction. In an advantageous alternative embodiment, it is provided that the plug-in receptacles 6 run in a horizontal direction. As a result, further carriers 2, 3 are not mounted from above in the vertical direction, but by lateral displacement or by lateral pivoting. A U-shaped disc inserted from above, for example, can serve as a securing element, which prevents lateral displacement of the plug-in element 5 in the associated plug-in receptacle 6 .

In the exemplary embodiment, each connecting element 7, 8, 9 carries a plug-in element 5 and a plug-in receptacle 6. The plug-in elements 5 and plug-in receptacles 6 are designed in such a way that each second connecting element 8 can be connected either to a first connecting element 7 or 9 or to a further second connecting element 8. To connect two second connecting elements 8 together is one of Connecting elements 8 are arranged rotated relative to one another by 180° about the longitudinal central axis 31 of the associated carrier 2, 3, so that each plug-in element 5 comes to lie adjacent to a plug-in receptacle 6. All plug-in elements 5 are of identical design and are designed as screws which allow the plug-in connections to be adjusted by screwing them in or out. All sockets 6 are - except for the length of the slot up to the end position of the plug element 5 in the connected state of the connecting elements 7, 8, 9 - performed identically. All connecting elements 7, 8, 9 and the suspension element 10 are formed by connecting brackets 22, 23, 24 and enclose the associated longitudinal member 2 or cross member 3 completely. At least one connecting device 34 for connecting the two individual parts 25 of the connecting brackets 22, 23, 24 also serves to fix the position of the corresponding connecting bracket 22, 23, 24 in the longitudinal direction of the associated carrier 2, 3.

All connecting brackets 22, 23, 24 are designed as bent sheet metal parts into which only the plug-in elements 5 are screwed to form the connecting elements 7, 8, 9 and on which the connecting devices 34 are arranged. This results in a simple structure.

For a system of connecting elements for connecting carriers 2, 3, only two or three different types of connecting elements 7, 8, 9 are required. for the inside 1 System shown, first connecting elements 7 and second connecting elements 8 are provided. For that in the Figures 4 to 6 System shown first connecting elements 9, suspension elements 10 and second connecting elements 8 are required. As a result, a modular system for connecting carriers 2, 3 can be created in a simple manner.
