Description

[0001] The invention relates to a ground support for a cable carrying system.

[0002] Cable support systems are used to carry cables and / or lines, typically within buildings such as factory floors. To support these cables and lines, cable support systems have anchor points to which the cables and / or lines can be connected or secured. Cable supports, such as cable ducts, may also be provided.

[0003] In some cases, the cable support system is mounted on the ground side, for example on a portion of the hall floor, a decking, or a beam. If the cable support system is mounted on the hall floor, it is usually designed to be walked on and should therefore be stable enough so that people can easily stand on and walk on it without damaging the cable support system or even the wiring or cables above it.

[0004] For example, document US 2009 / 0090549 A1 discloses a cable carrying system installed on the ground side.

[0005] Part of the cable support system installed on the ground side is the ground supports. These ground supports support the upper cladding (Verschlusslänge) at a specified distance via rods that rest against the ground. The installation space for laying cables and / or lines, such as power supply lines, is bounded on the top by the cladding and on the bottom by the ground; the cladding is spaced apart from the ground or raised by the ground supports. This ground support has a rod that can be mounted on the ground side and, on the top side, a support for the cladding. The support is usually a crossbeam that protrudes from the rod. The closing plates that connect the ground supports at the side can also be designed to form a closed cable duct consisting of the ground, the cladding and the side plates.

[0006] The covering plate can be, for example, a cover plate, or even a U-shaped, downward-pointing leg forming a side panel. Alternatively, a cable support can be provided as a covering plate on the crossbeam, on which or in which the cables and lines are laid, thereby forming two spatially separated, layered cable paths between the floor and the cable support, on the one hand, and within the cable support, on the other. Such a cable support is usually closed on the top by a covering plate, such as a cover plate.

[0007] The applicant has commercially launched a floor support for this type of cable support system under the model BSS 190 xxx FT. This floor support has a floor panel mounted on the ground side. Two C-shaped profiles protruding from the floor panel and pointing toward each other at their rear sides are welded to the floor panel and serve as the rods of the floor support. A C-shaped crossbar, with its rear sides pointing upward, is welded to the upper ends of the two C-shaped profiles forming the rods.

[0008] To install the floor supports, floor screws are fastened to the ground, such as a hall floor. Sliding nuts are then placed in the C-shaped profiles provided as rods to secure mounting materials, such as pipe clamps, to the C-shaped profiles to secure the wiring. Additionally or alternatively, cables and / or wiring can be laid on the floor next to the rods. Finally, the sheathing, supported by the crossbeams, is installed.

[0009] In ground supports, both the manufacture and installation of ground supports or cable carrier systems can be improved:

[0010] During the manufacturing process, the entire ground support must be hot-dip galvanized to provide the necessary corrosion protection for welding, which requires a lot of energy and requires post-processing of the openings and outflow edges.

[0011] During installation, it is particularly important to secure the floor supports to the ground in the longitudinal direction of the crossbeam to prevent the cable support system from tilting, especially if the cable support system could be stepped on and exert forces on the edges of the sheathing. However, this is sometimes difficult or even impossible because the crossbeams protrude from the floor. This makes it difficult or even impossible to easily insert drill bits and screwdrivers into the precise fixing holes under the crossbeams.

[0012] Furthermore, relatively expensive sliding nuts are used to secure the mounting material as a fastening base for additional fixings for cables, such as pipe clamps, which are also inserted into the profile forming the rod or have to be inserted before the profile passage opening is closed at the front end.

[0013] Holes are usually drilled on site in the beams to fasten the sheathing to them. This creates debris that can pose a safety hazard to the cables and lines installed in the cable support system and must be removed at great expense. This also needs to be taken into account when using drill screws.

[0014] Ground supports must be available in different sizes for different cable run cross-sections (height and width) and must also be designed for different weight classes. This results in a wide variety of products.

[0015] The technical problem to be solved by the present invention is to provide a ground support with a cover plate and a ground support arrangement to overcome the above-mentioned disadvantages.

[0016] This object is achieved by a ground support for a cable carrier system of the type described above having the features of claim 1 and a device of the type described above having the features of claim 16 .

[0017] Advantageous embodiments are apparent from the dependent claims and the description.

[0018] Compared to the prior art, the core feature of the present invention lies in the multi-piece design of the ground support: the ground support comprises a lower part and an upper part. The upper part is mounted on the lower part, which provides the support rod to be installed on the ground side, and the upper part can be designed in the form of a crossbar. The upper and lower parts are not welded together to form the ground support (integral), but are connected to each other via fixings. Not welding the two parts together saves energy. The lower part and / or the upper part can be a single piece, and the ground support as a whole should be considered as a two-piece or multi-piece construction.

[0019] The connection between the upper and lower parts can also be established in the factory or on site. In the latter case, the lower part has an outwardly projecting mounting plate or a base plate accessible from above, which is mounted at least on the ground side. The lower part rests on the ground, while the upper part, which usually projects beyond the rod, does not become an obstacle to installation. This allows for ground-side fastening even in a position in which the upper part projects from the rod by its longitudinal extension when the upper part is mounted.

[0020] In addition, before the upper part is installed, any mounting material to be installed can be assembled to the rod of the lower part more conveniently. Compared with the prior art, the upper part that has not yet been installed will not increase the difficulty of assembly.

[0021] The lower part, which includes the rod, has a significant influence on the height of the cable support provided by the ground support, while the upper part influences the width of the cable support. By providing a partition between the upper and lower parts, an interface is provided between the upper and lower parts for connecting the two parts. The interface can remain unchanged with respect to a number of specific dimensions (such as the distance between different fixings, the width of the socket, etc.). This means that a lower part of a first height can easily be combined with an upper part of different widths, and vice versa. Usually, a standardized interface is provided within one load class, while different interfaces are usually provided for different load classes. Such interfaces are usually designed with matching fixings. In this way, the number of different ground supports that need to be prepared in order to provide the necessary variety at the same time is greatly reduced. The fixings of the lower and upper parts are designed identically in different parts of the load class, so that any combination of lower and upper parts can be used.

[0022] By fixing the upper part to the lower part using additional fixings, a subsequent hot-dip galvanizing process during the production process is unnecessary when using galvanized parts (upper and lower parts), and the two parts are connected by welding. The lower part and / or the upper part can be designed in particular as bent parts, in particular as stamped bent parts. For example, the lower part can be designed to be essentially U-shaped, with a base plate and two mutually opposite side walls connected to the base plate and forming support rods. The upper part is then mounted on the upper end of the side walls. The upper part can also be trimmed in a U-shaped or C-shaped manner or provided by a corresponding profile. To prevent corrosion, the trimmed parts can be made of corrosion-resistant material or pre-coated material, such as galvanized material, which is much more cost-effective than hot-dip galvanizing. Pre-coated materials are already coated with an anti-corrosion layer before processing, so that no subsequent coating is required. Corrosion-resistant materials must also be post-treated after welding, such as pickling and subsequent passivation in the weld area.

[0023] The side walls are preferably formed on the mutually opposing sides of the base plate, usually by corresponding curvature thereof. The base plate provides cutouts, through which the lower part can be fixed to the ground, preferably with slots oriented transversely to one another for precise alignment. The longitudinal extension of the base plate usually coincides with the longitudinal extension of the upper part to ensure lateral support of the cable support system.

[0024] The base plate can have two support areas, via which it contacts the ground and is mounted on it. The aforementioned recesses are arranged within the support areas. The base plate can have a recess between these support areas, or the floor support can at least have a distance from the ground. The support areas between them should not be too large. The aim is to provide local support for the floor support on the ground, in order to overcome possible unevenness in the ground between the mounting areas. For example, the floor support can be mounted at the transition between panels of a hall floor, since hall floors are naturally uneven, and the entire downward-facing part of the floor support does not have to rest on the ground. This way, uneven edges at the panel boundaries can be compensated without the floor support being unstable on these unevennesses.

[0025] To attach the upper component to the lower component, a receptacle is preferably formed on the support rod into which the upper component can be inserted. The receptacle can be provided by the side walls of the support rod. This creates a receptacle space between the end sections of the side walls, into which the upper component can be inserted. The upper component is then at least partially surrounded by these side wall sections. The fixing elements on the lower component side for establishing a connection with the upper component are preferably located on the side wall sections of the lower component, which provide a peripheral frame for the receptacle space.

[0026] In order to achieve a frictional connection between the upper part and the lower part, different fasteners can be used, such as at least one screw connection and / or a latch connection, or a combination thereof. For example, corresponding or complementary latch structures can be provided on the upper part and the lower part, which can engage with each other in a form-fitting manner when the upper part is installed. The latch structure can be manufactured by a stamping process without requiring much effort and can provide a higher fixing force with a minimum amount of assembly work. For example, the lower part can have a male latch structure, such as a latching protrusion, while the lower part has a female latch structure, such as a groove, and when the upper part is installed, the male latch structure engages with the groove. For a form-fitting connection, the male latch structure is usually made of a material surrounding the latch structure, and the end face of the metal plate that is separated from the surrounding material and provides the latch structure is preferably oriented in the load direction. The material oriented in the load direction has a higher resistance torque.

[0027] The end sides of the latching structure preferably abut against each other in the direction of gravity when installed. In this way, the main load direction, i.e. the direction of gravity, just can obtain particularly safe support, which is favourable for the cable carrying system that can be walked on.

[0028] In many cases, it is necessary to provide a plurality of latching structures, which may also be arranged opposite one another, preferably aligned with one another.

[0029] At least one male latching structure typically extends into the receiving space. If the receiving space is provided by the side walls of the lower component and the upper component is accommodated between the side walls, the side walls can elastically expand during assembly to create space for the male latching structure when the upper component is inserted. Due to the elasticity of the material of the lower component, once the male latching structure engages the female latching structure, the side walls move backward. In this way, the lower component is secured to the upper component.

[0030] To ensure this latching connection, or as an alternative, at least one securing element, such as a sheet metal fastener, a rivet or cotter pin connection or a guide element, can be provided, which prevents unintentional bending. Based on this, if necessary, the direction of action of the fastening element is usually in the direction of expansion of the side wall. However, preferably, screw connections are provided between the upper part and the lower part, also approximately in the direction of expansion of the side wall. Their longitudinal extension direction usually coincides with the direction of gravity. The two side walls are preferably screwed to the upper part at least at one point, preferably at multiple points. This also stabilizes the lower part when subjected to torsional loads. If the lower part is designed to be essentially U-shaped, it is closed by the upper part in its extension direction, thereby preventing shear movements of the side walls.

[0031] Preferably, the rod has a first width along its extension in the section facing the base plate, and a second, smaller width in the adjacent section. The width direction is generally oriented along the longitudinal extension of the upper part. The first width is at least twice, preferably three times, the second width. The section of the first width adjoins the section of the smaller second width, preferably substantially continuously, for example forming a slope with an angle of approximately 7° to 20°. The first section does not need to be particularly high. Typically, it only needs to be 1 / 5 or 1 / 6 the height of the section of the second width in the longitudinal extension of the rod, or less. This stabilizes the ground support and the base plate on the ground side.

[0032] Alternatively, or in a single position, the end of the lever facing the upper part can also have a third width that is greater than the second width, so that this section protrudes beyond the second section. The third section is preferably a receptacle for the upper part. In particular, it is provided that the fixing means for fixing the upper part to the lower part can be arranged in the region of the third section that protrudes beyond the second section. This ensures particularly secure force introduction due to the large lever arm.

[0033] The thickness of the rod is generally less than its width in the entire longitudinal extension direction of the rod. The thickness of the rod is oriented in the longitudinal extension direction transverse to the width. For example, the distance between the two side walls is less than its width.

[0034] If the rod is formed by the side walls of a substantially U-shaped lower part, provision can be made to stabilize the side walls by forming stabilizing legs on at least one side of the side wall, preferably on both sides, that extend approximately at right angles to the side wall. The stabilizing legs can be bent away from the side wall. The stabilizing legs can extend only along a portion of the rod's extension direction, preferably the region of the aforementioned second section. When a weight is applied in the direction of gravity, the stabilizing legs can counteract bending of the side walls. Both side walls preferably have at least one, preferably two, stabilizing legs.

[0035] The stabilizing legs can be designed so that a closing projection is provided in the second section of the side wall by projecting toward the opposite region of the other side wall. The stabilizing legs can also respectively engage with the mutually opposite side walls or the material connected thereto and thereby also support the side walls against each other.

[0036] Particularly preferably, both side walls have stabilizing legs pointing opposite each other on both sides of their longitudinal extension. These stabilizing legs are preferably comb-shaped and mesh with each other at their ends. This makes it possible to provide a particularly torsionally rigid rod in a simple manner without requiring joint connections.

[0037] The free stabilizing leg ends are preferably designed in a comb-like configuration, with the edges and corresponding grooves inclined at an angle to the vertical so as not to hinder demolding when the two side walls are bent apart. This angle is at least approximately 45°, preferably at least 55°, relative to the longitudinal extension of the support rod. This ensures that, on the one hand, the side walls are rigid and can be supported against shearing movements, while, on the other hand, the opposing side walls can be easily bent apart, allowing the upper part to be inserted into the receptacles provided by the side walls despite the comb-like engagement.

[0038] For further stabilization or in areas of the side wall without stabilizing legs, one or more stabilizing depressions oriented at an angle of approximately 45° to the longitudinal direction of the rod can be provided in the side wall.

[0039] Preferably, the side walls are reinforced along substantially their entire shaft extension by stabilizing legs and / or one or more recesses. Nevertheless, the transition from the base to the side walls serves as a resilient connection, allowing the two side walls to be bent apart in order to install the upper part in the container provided by the side walls. Due to the shaft extension, the bending angle at the transition is very small along the opening path defined in the receptacle for inserting the upper part.

[0040] To stabilize the base plate, in particular to prevent twisting, support legs can be arranged at both ends of the base plate, pointing upward transversely to the walls. These support legs stabilize the base plate transversely to the side walls, so that the side walls are supported in contact on these support legs and also prevent mutual movement, which could occur, for example, during longitudinal bending under load.

[0041] To attach pipe clamps or other mounting materials to the pole, the pole is preferably provided with at least one, but preferably multiple, threaded sockets for attaching the mounting material to the pole. The threads are preferably designed as threaded penetrations. This makes installation faster and simpler; compared to conventional installation, installation time can be reduced by up to 80%. The prepared threaded penetrations prevent the generation of unnecessary debris during installation.

[0042] The upper part is preferably a C-shaped profile in its cross-section. It has a back and two legs formed on the back and bent at their free ends. The upper part can be adjusted relative to the lower part so that the opening of the profile points upward or downward. If the opening of the C-shaped profile points upward, a large weight can be transferred through the upper part without the risk of bending. If the back of the C-shaped profile points upward, a continuous mounting base can be provided, for example, for cable ducts. There is at least one, and usually several, offset openings for passing connecting elements, such as screw connections. Preferably, at least one, and preferably several, offset threads, such as threaded penetrations, are provided on the mounting base to enable the installation of other elements of the cable support system, also without generating debris. The advantage of the latter design is that the installation direction can only be from top to bottom, which greatly simplifies the installation process.

[0043] The upper part can also be chamfered at its distal end so that the surface section also points toward the distal end of the upper part. This closes the cavity provided by the C-shaped profile at the end. Elements, such as lining panels, can be attached to these surface sections on both sides relative to the upper part. The downward-pointing legs of the U-shaped cover can also be fastened to these surface sections as coverings, for example, using essentially horizontal screw connections. This prevents the upward-pointing screw heads of vertical screw connections from being in the direction of gravity, thereby avoiding a tripping hazard.

[0044] In a further development, a fixing attachment connected to the upper part is provided as an accessory to the ground support. This fixing attachment is designed in the form of a sliding nut and forms a mounting base, for example, for additional mounting material or other elements of the cable support system. The fixing attachment comprises two spaced-apart clamping plates, which point toward each other via their planar extensions. The two clamping plates are connected to each other by at least one, and preferably a plurality, spaced-apart tabs, which are typically connected to the edges of the two clamping plates, for example, molded onto these edges. This fixing attachment can be designed as a stamped and bent part, for example, made of galvanized material strip; the fixing attachment can be folded together at one or more tabs in a book-like manner so that the clamping plates point toward each other.

[0045] The two clamping plates are spaced apart from each other and have a spacing such that the bent leg projections of the legs of the C-shaped upper part engage between the two clamping plates when pre-assembled on the C-shaped profile. The fixing attachment is held in place on the C-shaped profile by frictional engagement due to the contact between the clamping plates and the leg projections and the clamping forces of the two clamping plates, which are directed towards each other, exerted on the clamping plates by the tabs. In order to provide a certain elasticity between the two clamping plates, one or more tabs can be designed in a U-shaped manner. The U-shaped design provides elasticity in the direction of separation between the two clamping plates. In this context, one or more tabs are preferably arranged only on one side of the clamping plate so that the clamping plate can be bent from the other side. In this context, it can also be understood that the fixing part is a bent part, preferably a stamped bent part.

[0046] Furthermore, the two clamping plates have mutually aligned through-holes, wherein one clamping plate, the first clamping plate, has a threaded hole in the through-hole, while the diameter of the through-hole in the second clamping plate is larger than the inner diameter of the threaded hole. The first clamping plate is arranged in the cavity of the C-profile, pointing toward the back of the C-profile. A screw can be inserted through the through-hole and can also be used to secure mounting material or other components of the cable carrier system to the fixing element. The pressure exerted by the screw head on the second clamping plate and the tension exerted by the threads on the first clamping plate clamp the two clamping plates together. The two clamping plates are clamped together with the leg projection of the C-profile in between, thereby clamping the fixing accessory to the C-profile.

[0047] It is understood that when clamped, the length of the clamping plate is greater than the spacing of the leg projections of the C-shaped profile (the clear width of the C-shaped profile in the area of ​​the leg projections) so that the leg projections and the clamping plate overlap during installation. In addition, the length of the first clamping plate is at least less than the inner width of the leg.

[0048] Since the web spans the distance between the two clamping plates and is also arranged between the leg projections for this purpose, this arrangement does not hinder the rotation of the clamping plates during assembly.

[0049] In order to attach the fixing accessory to the C-profile, the fixing accessory can be moved to one end of the C-profile. However, in a preferred design, the width of the fixing accessory in the area of ​​the first clamping plate and in the area between the leg projections is smaller than the clear width between the leg projections in the installation direction. In this orientation, the fixing accessory can be inserted into the C-profile at any position on the C-profile. The fixing accessory is then rotated about its height axis so that the clamping plate is rotated above or below the leg projections and the fixing accessory reaches the clamping position. Preferably, in this design, the second clamping plate partially protrudes beyond the outer edge of the first clamping plate in the installation direction and contacts the leg projections of the C-profile on the outside. This provides a stop that prevents the fixing accessory from extending further into the space of the C-profile enclosed by the leg projections. This simplifies the process of attaching the fixing accessory to the C-profile.

[0050] It is also preferably provided that, if the fastening attachment has a corresponding outer contour, the fastening attachment can be moved into the C-profile by means of the first jaw only in one orientation, in which orientation the second jaw provides a stop.

[0051] It is also preferably provided that the diagonally opposite corners of the first clamping plate are chamfered or rounded. These corners are used to facilitate rotation of the fastening attachment when it is attached to the leg protrusion. Thus, when the first clamping plate is slid onto the leg protrusion, its edge is angled relative to the extension of the leg protrusion edge, for example, at least 7° to 10°. This facilitates sliding. The edge of the clamping plate to be slid and / or the edge of the leg protrusion may also be chamfered to serve as a guide bevel.

[0052] Of course, the above-described embodiments regarding the fixing attachment can also be used in combination with another C-shaped profile that is not part of the ground support.

[0053] A ground support mounted in this way therefore has a large number of possible connection points, which can be provided at the locations required for further assembly.

[0054] In the upper part, a thread, such as a thread penetration portion, can also be provided at an appropriate position to install the cladding plate. If the upper part is designed to a C-shaped profile, these threads are especially designed at the back of the C-shaped profile.

[0055] Cable supports, such as cable ducts, can be connected and screwed to the top of the upper part as a covering plate. This allows the cable supports to be elevated from the ground. Cables and / or pipelines can be laid on the support rods on the one hand and on the cable rack on the other, creating a spatial and organizational separation between the two areas.

[0056] Preferably, the cable holder has a series of elongated holes along its longitudinal extension, preferably on both sides of its longitudinal extension. The upper part of the ground support also has at least one, and preferably also on both sides, threaded bushings or threaded penetrations, which are arranged at corresponding locations on the cable holder. The cable holder can be fastened to the upper part using screws that pass through (any) elongated holes in the cable holder.

[0057] The present invention will be further described below with reference to the accompanying drawings according to the embodiments. In the accompanying drawings:

[0058] Figure 1 An exploded view of the ground support is shown,

[0060] Figure 3 Show Figure 1View of the ground support shown, fitted with pipe clamps,

[0062] Figure 5 A three-dimensional view showing the fixed attachment,

[0063] Figure 6 Show Figure 5 A side view of the fixing attachment is shown,

[0064] Figure 7 Show Figure 5 Top view of the fixing attachment shown.

[0065] In the drawings, the same components are marked with the same reference numerals.

[0066] Figures 1 to 3 Shown is a ground support 1 which is installed only on the ground in order to form a traversable cable carrying system. Figure 3 On the floor B shown, such as a hall floor, the floor support is composed of two parts: a lower part 2 and an upper part 3. The lower part 2 has a base plate 4 and support rods 5 for mounting the lower part 2 on the ground side.

[0067] It can be seen that the base plate 4 is interrupted (recessed area 4 c ) and provides two support areas 4 a , 4 b , on which the base plate 4 is raised from the ground B and is fixed.

[0068] The lower part 2 is a stamped and bent part made of a galvanized material strip. It is essentially U-shaped: the base 4 represents the connecting edge of the U, and the side walls 6 and 7 represent the legs of the U. The side walls 6 and 7 are not directly connected to each other, as this would damage the galvanizing layer; that is, they are not welded together.

[0069] The side walls 6 and 7 are substantially mirror-symmetrical and partially complementary to one another, as will be explained in greater detail below.

[0070] The two side walls 6 and 7 can be divided, starting from the base plate 4, in the longitudinal direction of the rod into three sections of different widths: a first section of a first width 8, a second section of a smaller second width 9, and a third section of a larger third width 10. To stabilize the second sections, the side walls 6, 7 have stabilizing legs 11, 12, which extend perpendicularly from each side wall 6, 7 along both sides of the rod.

[0071] The free ends of the stabilizing legs 11, 12 mesh with each other in a comb-like manner, with the respective grooves or projections, in their non-vertical configuration, at least at an angle of approximately 55° to the vertical. The meshing of the end faces of the stabilizing legs 11, 12 prevents shearing movements of the side walls 6, 7 and prevents twisting of the support rod 5.

[0072] In the sections with greater width (widths 8 and 10 ), no stabilizing legs are provided along the sides of the side walls 6 , 7 . These sections are provided with depressions 13 oriented at an angle of 45°, which increase the bending strength of these areas.

[0073] The base plate 4 extends laterally by the support areas 4a, 4b beyond the section of the second width 9 and has at its distal end chamfered support legs 14, 14.1 extending between the side walls 6, 7. The side walls 6, 7 are supported inwardly on these support legs 14, 14.1.

[0074] A threaded penetration 15 pointing toward the longitudinal section of the base plate is provided in the support rod 5 or in the region of the second width 9. Figure 3 ) can be mounted on the threaded penetration in order to fix the tube 17 to the support rod 5 or the ground support 1.

[0075] The upper part 3 is also a stamped and bent part made of a galvanized material strip. To form the ground support 1, the upper part 3 is inserted between the two side walls 6, 7 into the upward-pointing receptacle 18 formed by the side walls 6, 7. To secure the upper part 3 to the lower part 2 or to the side walls 6, 7, the side walls 6, 7 have mutually opposed, aligned positive latching structures 19, here designed as latching projections extending from the side walls 6, 7. These latching projections engage with complementary negative latching structures 20, here designed as grooves, in the upper part 3. The positive latching structures 19 extend into the receptacle 18 and thus into the space between the side walls 6, 7. The end faces of the positive latching structures 19 face the direction of gravity G, thereby generating a greater resistance torque opposite to the direction of gravity G. The upper part 3, thus assembled, is supported on the lower part 2 in the direction of gravity G.

[0076] To insert the upper part 3 into the receiving portion 18, the two side walls 6, 7 are separated. Since the two side walls 6, 7 are connected to each other only via the base plate 4, this does not cause a major problem; the length of the support rods 5 or the side walls 6, 7 is such that only a small angular deformation is required for the transition from the base plate 4 to the side walls 6, 7, so that the positive latching structure 19 can be retracted to allow the upper part 3 to be inserted into the receiving portion 18.

[0077] In order to prevent unintended bending and to reinforce the entire ground support 1, it is provided that the side walls 6, 7 are connected by screws 21. The connection is respectively made adjacent to the snap connections 19, 20. The upper part 3 and the lower part 2 are firmly connected to one another by the snap connections 19, 20 and the screw connection 21, wherein the lower part 2 is additionally stabilized against twisting by the upper part 3.

[0078] The upper part 3 also has threaded penetrations 22 for mounting coverings such as cable supports and / or cover and side panels.

[0079] Figure 4 The cross section of the upper part 3 is shown. The upper part 3 is designed as a C-shaped profile in its cross section. The C-shaped profile consists of a back 23 and legs 24, 25 formed on the back, which legs 24, 25 themselves have curved leg projections 26, 27.

[0080] Figures 5 to 7 The fastening fixture 28 shown can be connected to the upper part 3 designed as a C-profile. The fastening fixture 28 consists of two spaced-apart clamping plates 29, 30, which are connected to each other by two U-shaped tabs 31, 31.1 formed on the edges of the clamping plates 29, 30. The clamping plates are spaced at a distance 32 from each other so that the leg projections 26, 27 can be arranged between the two clamping plates 29, 30 and simultaneously exert a clamping force on the clamping plates 29, 30 via the tabs 31, 31.1, so that during preassembly, the fastening fixture 28 is held on the upper part 3 designed as a C-profile by frictional engagement.

[0081] To mount the fastening fixture 28 on the C-shaped upper part 3, the fastening fixture is inserted between the leg projections 26, 27 in a first, mounting direction until the first clamping plate 29 is mounted on one side of the leg projections 26, 27 and the second clamping plate 30 is mounted on the other side. The fastening fixture 28 is then rotated about its height axis so that the first clamping plate 29 is rotated onto the leg projections 26, 27. In this way, the leg projections 26, 27 are clamped between the two clamping plates 29, 30.

[0082] In order to place the fixing accessory 28 in the space enclosed by the side feet 24, 25, the first clamping plate 29 has a width 33 in the installation direction, which is smaller than the clear width 35 between the side foot protrusions 26, 27 (here including the protruding webs 31, 31.1 in this area), and a length 34 that is greater than the clear width 35 between the side foot protrusions 26, 27 and smaller than the inner width 36 between the two side feet 24, 25.

[0083] Furthermore, the corners 37, 38 of the first plate 29, which are opposite one another along the axis, have a radius, which simplifies the rotation of the first plate 29 on the leg projections 26, 27. The chamfered edges 37, 38, which are provided starting from the side of the first plate 29 facing the second plate 30, further simplify the assembly process because tilting is prevented.

[0084] In this rounded region, the second jaw 30 projects from the first jaw 29 , so that the second jaw 30 provides a stop, which rests on the outside against the leg projections 26 , 27 in the installation direction.

[0085] The two clamping plates 29, 30 each have a through-hole 39, 40. The through-hole of the first clamping plate 29 has a threaded passage 40. If the fastening element 28 is previously mounted in the C-profile, so that the leg projections 26, 27 are positioned between the clamping plates 29, 30, the mounting material can be fastened to the fastening element 28 using screws (not shown in detail). The pressure exerted by the screws on the two clamping plates 29, 30 presses them together and thereby additionally clamps them against the leg projections 26, 27.

[0086] The present invention is described in conjunction with the embodiments. Without departing from the scope of protection described in the claims, technicians can also implement the concept of the present invention through many other design solutions without further detailed description in these embodiments.
