[0028] The means for positive force transmission are preferably designed in the form of a groove, a cross groove, a hexagon socket and an external hexagon, wherein the means are particularly preferably designed in the form of a hexagon socket.

[0029] Advantageously, the height can be adjusted from the upper part of the screw by means of a tool. Thus, the height can be adjusted in the installed state of the groove and / or the support structure. This also simplifies installation, since the height can be adjusted after installation.

[0030] Preferably, the fastening element contains plastic, preferably non-conductive plastic. More preferably, the fastening element consists essentially of plastic, preferably non-conductive plastic. Preferably, the fastening element is non-conductive. By means of such a fastening element, the groove and / or the support structure can be electrically isolated from the screw with the base. This enables the use of different materials, for example galvanized steel and stainless steel, in the groove and / or the support structure and the screw with the base.

[0036] The present invention is also based on the following concept: a system is described, which includes: a device according to the present invention for supporting a groove and / or a support structure and for adjusting the height of the groove and / or the support structure; and a groove and / or a support structure, which has a lateral receiving portion, which is used to at least partially, preferably laterally, push a fastening element into the groove and / or the support structure so that in the installed state, a plate or section of the preferably bottom of the groove and / or the support structure engages in at least one groove of the fastening element.

[0037] Preferably, the groove and / or the support structure has a through hole in the bottom of the groove or the support structure for accommodating the screw. In one embodiment, the diameter of the through hole corresponds to the diameter of the screw, so that a form fit is caused. In one embodiment, the diameter of the through hole is larger than the diameter of the screw, so that no form fit is caused.

[0038] Preferably, the groove and / or the support structure has a receptacle for a web of the fastening element in the bottom of the groove or the support structure.

[0039] Preferably, the receiving portion of the groove or support structure respectively forms a lateral receiving portion for at least partially, preferably laterally, pushing the fastening element into the groove and / or support structure, a through hole in the bottom of the groove or support structure for receiving the screw, and a receiving portion in the bottom of the groove or support structure for the web of the fastening element.

[0040] The system can be present in an installed or disassembled (in parts). In the installed state, the system preferably comprises: at least four devices according to the invention for supporting the groove and / or support structure and for adjusting the height of the groove and / or support structure, and the groove and / or support structure with at least four lateral receptacles for at least partially, preferably laterally, pushing in the fastening element, and, if necessary, at least four through-holes in the bottom of the groove or support structure for receiving the screw and, if necessary, at least four receptacles for the tabs of the fastening element.

[0041] Preferably, the fastening element is connected to the groove and / or the support structure in a form-fitting manner in the installed state. The term "form-fitting connection" means that the connection of the fastening element to the groove and / or the support structure is ensured by the shaping of the component without a continuously acting force (preload). This applies to a two-sided form-fitting connection acting in two axial directions, as well as to a one-sided form-fitting connection acting in a single axial direction. In contrast to a form-fitting connection, in the case of a force-fitting connection, the connection of the components is achieved by a continuously acting (external) force.

[0042] Preferably, the fastening element electrically isolates the screw and the groove and / or the bearing structure from one another in the mounted state.

[0043] Preferably, the groove and / or the bearing structure are / is not connected to the screw in the installed state via a component having an external thread and an internal thread.

[0044] Preferably, the system comprises a reinforcement element for reinforcing the groove and / or the support structure. Preferably, the system comprises at least two reinforcement elements for reinforcing the groove and / or the support structure.

[0045] The reinforcing element serves to reinforce the body of the groove and / or support structure. In the event that the groove and / or support structure is loaded from the top, the force is transmitted to the height-adjustable base via the lateral grate supports. Since the base is not in a straight line with the introduction of the force, a torque is generated here, which causes the bottom of the groove and / or support structure to bend inwards. In particular, if the reinforcing element or the reinforcement profile is designed in a U-shape, the reinforcing element or the reinforcement profile prevents this effect. The reinforcing element preferably has a recess for accommodating a fastening element. The fastening element connects the groove and / or support structure and the reinforcing element to each other by pushing them apart.

[0046] The reinforcement element preferably comprises a sheet metal, which particularly preferably has a U-shape. The U-shaped design of the reinforcement element preferably enables a form-fitting connection to the fastening element along the longitudinal sides of the fastening element.

[0047] Each reinforcing element preferably comprises at least two receptacles for at least partially pushing in or embedding a respective fastening element. Preferably, the receptacles are used to accommodate a respective tab of the fastening element. In other words, preferably, the fastening element can be pushed into the reinforcing element along its longitudinal axis at least partially through the receptacles of the reinforcing element. Preferably, two receptacles per fastening element are involved. It is particularly preferred that the two receptacles for at least partially pushing in or embedding a respective fastening element are arranged at opposite ends of the reinforcing element. Preferably, the two receptacles for at least partially pushing in or embedding a respective fastening element are arranged on the longitudinal axis of the reinforcing element.

[0048] Each reinforcing element comprises at least one through hole, preferably two through holes, for receiving a respective screw. In one embodiment, the diameter of the through hole corresponds to the diameter of the screw, so that a form fit is achieved. In one embodiment, the diameter of the through hole is greater than the diameter of the screw, so that no form fit is achieved. Preferably, the receiving portion of the reinforcing element is respectively formed as a receiving portion for at least partially pushing in a fastening element, in particular a tab of the fastening element, and a through hole for receiving a screw.

[0049] Not only the reinforcing element but also the groove and / or the support structure in the installed state extends substantially along its longitudinal axis in the horizontal direction. In the installed state, the longitudinal axis of the reinforcing element preferably extends perpendicularly to the longitudinal axis of the groove and / or the support structure.

[0050] The sections of the reinforcement element can be pushed into at least one groove of the fastening element or can be embedded therein. In the mounted state, the sections of the reinforcement element each engage in at least one groove of the fastening element or are embedded therein.

[0051] In the mounted state, the fastening element is preferably pushed into the reinforcement element such that the U-shape of the reinforcement element surrounds the longitudinal sides of the fastening element.

[0052] The reinforcing element is connected to the fastening element and the groove and / or the support structure in the installed state. At least one groove of the fastening element is used to connect the reinforcing element, the fastening element and the groove and / or the support structure. Preferably, the reinforcing element is connected to the fastening element and the groove and / or the support structure in a form-fitting manner in the installed state. The term "form-fitting connection" means that the combination of the reinforcing element, one / more fastening elements and the groove and / or the support structure is ensured by the shaping of the components without a continuously acting force (preload). As with the form-fitting for the one-side combination acting in a single axial direction, this is suitable for the form-fitting for the two-side combination acting in two axial directions. Unlike the form-fitting connection, in the case of a force-fitting connection, the combination of the components is achieved by a continuously acting (external) force.

[0053] In addition, the invention is based on the idea of ​​specifying a method for supporting a groove and / or a support structure and / or for adjusting the height of a groove and / or a support structure. Preferably, a device according to the invention and / or a system according to the invention is used here. The method comprises the following steps:

[0054] i) if necessary, introducing a form-fitting element, in particular a nut, into a receptacle for a form-fitting element, in particular a nut, of the fastening element (only if the fastening element for connection to the screw comprises a receptacle for a form-fitting element);

[0055] ii) pushing the fastening element at least partially, preferably laterally, through the lateral receptacle of the groove and / or the support structure into the groove and / or the support structure, so that a sheet or a section, preferably of the bottom, of the groove and / or the support structure engages in at least one recess of the fastening element;

[0056] iii) guiding the threaded rod through a through-hole of the fastening element and connecting the threaded rod with its external thread to an internal thread of the fastening element or to an internal thread of a form-fitting element, in particular a nut, in a receptacle for a form-fitting element, in particular a nut, of the fastening element;

[0057] iv) Optionally: connecting the first end of the screw to the base so that the screw is rotatably supported in the base;

[0058] v) rotating a screw for adjusting the height of the groove and / or the support structure,

[0059] Here, step i) can be carried out after step ii) and step iv) can be carried out at any time.

[0060] The method preferably comprises performing the steps a plurality of times until a number of devices according to the invention, preferably at least four devices, are fastened to the trough or support structure which are sufficient to support the trough or support structure.

[0061] The advantage of the method is quick and simple installation. The height can also be adjusted simply from above after installation.

[0062] Preferably, the method also comprises the step of pushing a respective fastening element at the opposite ends of the reinforcing element into the two receptacles, so that at least one section of the reinforcing element respectively engages in at least one recess of the fastening element. Preferably, the respective section of the reinforcing element is arranged in the at least one recess of the fastening element below the groove and / or the sheet or section of the support structure.

[0063] Preferably, guiding the screw through the through-hole of the fastening element also includes guiding it through the through-hole of the reinforcement element.

[0064] The descriptions of the device according to the invention, the system according to the invention and the method according to the invention can be combined with one another as desired, provided that their contents do not contradict each other. BRIEF DESCRIPTION OF THE DRAWINGS

[0078] Figure 1 The system according to the invention is shown, which has a channel 20 and four devices according to the invention 10. The devices 10 according to the invention support the channel 20 and are suitable for adjusting the height of the channel 20 steplessly.

[0079] Figure 2The system according to the invention is shown, which has a support structure 20 and four devices 10 according to the invention for supporting the trench and for adjusting the height of the support structure.

[0080] Can also be adjusted from above without difficulty after installation Figure 1 The height of the groove 20 or Figure 2 The height of the support structure 20 in the device 10 is obtained by removing the grille 22 in order to access the support structure 20 in the device 10. Figure 3 The hexagonal portion 18 is shown in FIG.

[0081] Figure 3 A hexagon socket 18 is shown, which forms the end of each of the screws 12. The other end of the screw 12 is rotatably supported in the base 16. By rotating the screw 12 due to the force transmission via the form fit of the hexagon socket 18, the screw 12 can be moved upward or downward depending on the direction of rotation. The fastening element 11 is connected to the external thread of the screw 12 via the internal thread and follows the upward or downward movement of the screw 12. Figure 1 The groove 20 or Figure 2 The bottom 23 of the support structure 20 in the fastening element 11 is embedded in the groove 13 of the fastening element 11. Through the shape-fitting connection of the fastening element 11 and the bottom 23, the groove 20 or the support structure 20 also follows the upward or downward movement of the fastening element 11 and the screw 12.

[0082] Figure 4 It is shown that the groove 13 divides the fastening element 11 into a (lower) part 11a and an (upper) part 11b. A web 11c connects the two parts. The fastening element 11 has a through hole, which is used to guide the screw 12 through. The groove 13 is arranged perpendicular to the longitudinal axis of the through hole.

[0083] Figure 5 A method for mounting a device 10 according to the invention or a system according to the invention is shown. The fastening element 11 comprises in its (lower) part 11a a receptacle 14 for a hexagonal nut 15. The internal thread of the hexagonal nut 15 serves to connect the fastening element 11 to an external thread (not shown) of a screw 12. The upper part 11b of the fastening element 11 is inserted through an at least partially lateral receptacle 21 (see FIG. 2 ) of a groove or a support structure 20. Fig.14) is pushed into the groove or support structure 20 so that a section of the bottom of the groove or support structure 20 engages in the recess 13 of the fastening element 11. The screw 12 is then guided from below through the hexagonal nut 15, through the through hole of the fastening element 11 and through the through hole in the bottom 23 of the groove or support structure 20. In this case, the outer thread of the screw 12 engages in the inner thread of the hexagonal nut 15 so that the screw 12, the hexagonal nut 15, the fastening element 11 and the bottom 23 of the groove or support structure 20 are fastened to each other. By rotating the screw 12 via the hexagonal inner portion 18, the height of the groove and / or support structure 20 can be adjusted from above at any time without further effort. The method in the example described includes carrying out the steps four times until four devices 10 are fastened to the groove or support structure 20 in order to adequately support the groove or support structure 20.

[0084] Figure 6 The cross section of the fastening element 11 is shown. Only the screw 12 is shown, the nut 15 is also missing in the receptacle 14. It is shown that the through hole of the fastening element 11 has a precisely defined constriction for the screw 12. This creates a thread barrier that prevents the screw 12 from being unintentionally unscrewed.

[0085] Figure 7 Depicted is a cross section of a fastening element 11 which carries two bases (sheet materials) of different thicknesses of a support structure 20. The sheet materials are shown in black. Even with bases 23 of different material thicknesses, the device 10 ensures a secure fit.

[0086] Figure 8-Figure 13 Further views of the fastening element 11 are shown.

[0087] Fig.14 The screw 12 is shown, which is guided through a through hole in the bottom 23 of the groove or support structure 20. The fastening element 11 is not depicted. The receiving part of the groove or support structure 20 forms a lateral receiving part 21 for at least partially pushing the fastening element 11 laterally into the groove and / or support structure 20, and a through hole in the bottom 23 of the groove or support structure 20 for receiving the screw 12, and a receiving part in the bottom 23 of the groove or support structure 20 for the tab 11c of the fastening element 11.

[0088] Fig.15 A cross section of the system according to the invention is shown. The groove or support structure 20 and the screw 12 are electrically isolated from one another by the fastening element 11 made of plastic. This enables a combination of different materials, for example galvanized steel and stainless steel.

[0089] Fig.16A reinforcement element 19 is shown, which serves to reinforce the body of the support structure 20. In the event of a load on the groove and / or the support structure 20 from above, the forces are transmitted via lateral grating supports to the height-adjustable base 16. Since the base 16 is not in a straight line with the introduction of the forces, a torque is generated here, which causes the base 23 of the support structure 20 to bend inwards. The reinforcement element or reinforcement profile 19 prevents this effect, in particular if it is designed in a U-shaped manner and accommodates the fastening element 11 in its U-shape. The fastening element 11 connects the support structure 20 and the reinforcement element 19 to each other by pushing them apart.
