[0002] Connecting device, cross element, carrier module part, and carrier

[0003] The present invention relates to a connecting device for a support of a structural device. The invention further relates to a cross element for a support of a structural device, a support module part for a support of a structural device, and a support for a structural device.

[0004] Construction engineering devices are known from the prior art. Such construction engineering devices include devices that are used in construction technology. For example, such construction engineering devices include scaffolding systems, crane systems, or similar devices that often have to withstand heavy loads. Such construction engineering devices are used, for example, for erecting or carrying out repair work on buildings or other structures. Construction engineering devices generally comprise support structures consisting of beams, which form a core element of such devices and are usually subject to high forces acting on the device. For example, workers carrying out work on a building can stand on a scaffolding system, or it can be used, for example, to hold or support formwork for the construction of a building.Examples of scaffolding systems include free-standing scaffolds, climbing scaffolds, suspended scaffolds, and supporting scaffolds, etc. Such devices are also used for other supporting structures for structural components, particularly formwork or similar. Examples of crane systems include construction cranes, overhead cranes, and load-bearing cranes, etc.

[0005] Since the demands on such devices are constantly increasing, for example buildings are to be built higher, larger, faster and / or more cost-effectively, or loads to be lifted are becoming ever larger and crane systems are becoming more universally applicable, there is therefore a continuous interest in developing improvements to such construction devices.

[0006] An object of the invention is therefore to describe improvements for a connecting device, a cross element, a support module part, and a support, which achieve a corresponding improvement of a structural device.

[0007] According to a first aspect, a connecting device for a support of a structural device comprises a first connecting element comprising at least one first receiving device for at least one first securing element and a first stop element. The connecting device further comprises a second connecting element comprising at least one second receiving device for the at least one first securing element and a second stop element which is intended to bear against the first stop element. The first stop element has a fitting piece protruding in the direction of a main extension direction of the support and the second stop element has a recess designed in the direction of the main extension direction of the support, wherein the fitting piece and the recess are designed to engage with one another when the first stop element bears against the second stop element.

[0008] One advantage of this is that it enables a simple, quick, and secure connection of various connecting elements to a support of a structural device. This allows corresponding structural devices to be assembled more easily, quickly, and safely.

[0009] A further advantage is that the interlocking of the fitting and the recess results in improved force transmission between the first and second connecting elements. This allows the connecting elements to withstand higher loads, improving the load-bearing capacity and stability of a beam and thus of a corresponding structural device.

[0010] In particular, in the connecting device described above, a first receiving device of the first connecting element and a second receiving device of the second connecting element are each configured to receive a first securing element. In other words, a first securing element connects a first receiving device to a second receiving device. Additional first securing elements can each additionally connect additional first receiving devices to additional second receiving devices.

[0011] For the purposes of this application, a securing element can be, for example, a bolt, a square, a hexagon, a latch, or any other corresponding securing element. For example, for the purposes of this application, securing elements are to be understood as releasable securing elements.

[0012] The connection between the first and the second connecting element is advantageously designed to be detachable so that the connecting device can be separated and reconnected as required.

[0013] The fitting piece of the first stop element is designed such that it can be inserted into the recess of the second stop element. For example, the fitting piece and the recess form a substantially positive connection. With such a positive connection, it is advantageous that forces can be transmitted particularly well between the connecting elements and thus dissipated. Furthermore, such a positive, play-free connection reduces wear on the stop elements that bear against one another.

[0014] The term "essentially" in this disclosure implies that certain manufacturing tolerances or minor deviations from the feature described thereby may exist. This applies accordingly to all places in this disclosure where these or comparable formulations are used.

[0015] The first and second stop elements further comprise, for example, stop surfaces against which the stop elements abut one another. The support is, for example, a horizontal support of the scaffolding system or a crane system, but can also be any other support, such as a diagonal support or a vertical support.

[0016] The main direction of extension of the beam represents a direction in which the beam mainly extends, i.e. the direction in which the beam has the greatest extent (usually the "length"). For a horizontal beam, which is usually oriented transversely to an acting force of gravity, this main direction of extension is usually in the horizontal direction. For a vertical beam, also called a upright or vertical strut, which is usually oriented parallel to an acting force of gravity, this main direction of extension is usually in the vertical direction.

[0017] According to at least one embodiment, the at least one first receiving device and the at least one second receiving device are designed to receive the at least one first securing element in a direction substantially perpendicular to the main extension direction of the carrier.

[0018] One advantage here is that a particularly secure and force-resistant connection is created between the connecting elements. Furthermore, this allows for easy insertion and removal of the at least one first securing element, since the carrier itself poses less of an obstacle to insertion / removal than with a different orientation. According to at least one embodiment, a main extension direction of the first stop element and of the second stop element is substantially perpendicular to the main extension direction of the carrier.

[0019] One advantage of this is that it achieves improved force transmission between the connecting elements. Since forces in a beam typically act along the beam's main extension direction, shear forces, for example, can be kept to a minimum. Furthermore, this alignment of the stop elements allows the connecting elements to be easily positioned against one another.

[0020] According to at least one embodiment, the at least one first receiving device has at least one first fastening tab, each of which has a first opening for receiving the at least one first securing element. Alternatively or additionally, the at least one second receiving device has at least one second fastening tab, each of which has a second opening for receiving the at least one first securing element.

[0021] The advantage here is that a particularly simple and secure connection option is provided between the connecting elements.

[0022] For example, the first and second receiving devices have corresponding fastening tabs with corresponding openings, which are then connected by means of a first securing element. Alternatively, however, only one of the receiving devices (first receiving device of the first connecting element or second receiving device of the second connecting element) can have such fastening tabs, which are connected to other types of receiving devices of the respective other connecting element by means of the first securing element. Such other types of receiving devices comprise, for example, openings in a flange, which will be explained in more detail later in this disclosure.

[0023] According to at least one embodiment, each first receiving device has at least two first fastening tabs, the first openings of which are arranged concentrically and which are designed to receive a first securing element for each first receiving device. Alternatively or additionally, each second receiving device has at least two second fastening tabs, the second openings of which are arranged concentrically and which are designed to receive a first securing element for each second receiving device.

[0024] One advantage of this is that improved stability of the connection is achieved by means of the at least one first securing element, since each first securing element per receiving device is inserted into at least two fastening tabs. This also reduces the risk of tipping between the connecting elements, since they are connected to one another at several points.

[0025] According to at least one embodiment:

[0026] - the at least two first fastening tabs and the at least two second fastening tabs are each arranged in a first edge region and a second edge region of the first and second stop elements, respectively; and / or - the at least two first fastening tabs and the at least two second fastening tabs are arranged in the first edge region and a central region of the first and second stop elements, respectively; and / or

[0027] - the at least two first fastening tabs and the at least two second fastening tabs are arranged in the central region and in a further central region of the first and second stop elements, respectively.

[0028] An advantage of attaching the concentrically arranged fastening tabs to opposite edge regions is that a high degree of stability of the connection between the first and second connecting elements is achieved. This design enables a wide spacing of the two fastening tabs, which are each connected by means of the same first securing element. Two central regions can be provided, particularly in a design in which an additional chord is arranged above the upper chord.

[0029] An advantage of attaching the concentrically arranged fastening tabs to a first edge region and a central region of the respective stop element enables a second edge region free of fastening tabs, which can thus be used, for example, to guide components, for example a so-called trolley.

[0030] The stop elements are arranged, for example, on the end faces of the connecting elements. The edge regions of the stop elements thus describe regions that are arranged on opposite edges of this end face. The central region is located essentially midway between these edge regions. For example, the first edge region is located on an upper side of the connecting elements, and the second edge region is located on an underside of the connecting elements. The central region is then located between this upper side and the underside. Both the edge regions and the central region can extend across the entire width of the stop elements.

[0031] According to at least one embodiment, the first connecting element has two first receiving devices which are designed to receive at least two first securing elements. Alternatively or additionally, the second connecting element has two second receiving devices which are designed to receive the at least two first securing elements. The two first receiving devices each comprise at least one first fastening tab, and the two second receiving devices each comprise at least one second fastening tab, wherein the first fastening tabs of the two first receiving devices and the second fastening tabs of the two second receiving devices are each arranged parallel to one another with respect to the main direction of extent of the carrier.

[0032] One advantage of this is that it provides additional stabilization of the connecting device. The risk of lateral tipping is reduced by the parallel arrangement and the connection with separate first securing elements.

[0033] The fact that the receiving devices are arranged parallel to each other means in particular that the parallel receiving devices are aligned in such a way that the first securing elements in the parallel

[0034] Mounting devices are parallel to each other.

[0035] According to at least one embodiment, the first fastening tabs, which are arranged parallel and next to one another, each form a tapered region which is designed to receive a part of the second stop element. Alternatively or additionally, the second fastening tabs, which are arranged parallel and next to one another, each form a tapered region which is designed to receive a part of the first stop element.

[0036] One advantage of this is that it allows for simplified positioning of the connecting elements when connecting them. By receiving the part of the other stop element in the converging area, the connecting elements are simultaneously brought into the correct position for connection when they are placed against one another.

[0037] According to at least one embodiment, the at least one first fastening tab and the at least one second fastening tab are attached to the first connecting element and the second connecting element offset from one another with respect to a direction perpendicular to the main direction of extension of the carrier. Alternatively or additionally, one of the at least one first fastening tab rests on one of the at least one second fastening tabs when the first stop element rests on the second stop element. One advantage here is that it enables secure force transmission and play-free fastening between the first and the second connecting element. In this way, the stability and security of the connecting device is improved and wear is reduced.

[0038] According to at least one embodiment, the at least one first opening of the at least one first fastening tab and the at least one second opening of the at least one second fastening tab, which are each provided for receiving a first securing element, are arranged concentrically.

[0039] One advantage here is that the first securing element can be inserted easily and without requiring great effort.

[0040] According to at least one embodiment, the at least one first securing element further comprises at least one opening for at least one second securing element, in particular for a transverse bolt and / or a securing ring.

[0041] An advantage here is that the respective first securing element is secured in the receiving device.

[0042] According to at least one embodiment, the fitting piece has a substantially quadrangular shape, in particular a rectangular shape. The recess has a substantially quadrangular shape, in particular a rectangular shape. One advantage here is that particularly good force transmission between the connecting elements can be achieved. Alternatively, the fitting piece and / or the recess can also have a polygonal shape. In this case, it can be advantageous that insertion of the fitting piece into the recess is facilitated.

[0043] According to at least one embodiment, the fitting piece and the recess are arranged closer to a first edge region of the first or second stop element than to a second edge region of the first or second stop element facing away from the first edge region. For example, the fitting piece and the recess are arranged centrally between the first edge region and a central region of the first or second stop element.

[0044] One advantage here is, for example, that the fitting piece and the recess can be arranged in particular in an area in which high forces occur in order to achieve good force transmission in this area in particular.

[0045] The first and second edge regions in this embodiment correspond in particular to the edge regions described above.

[0046] According to at least one embodiment, at least one side surface of the first stop element forms a substantially smooth surface with at least one side surface of the second stop element.

[0047] The advantage here is that there are no, or essentially no, steps or other unevenness at the connection points of the connecting elements. Particularly when additional components, such as a trolley, a roller carriage, or another movable element, are guided along the connecting elements, such a smooth surface is advantageous for the smoothest possible guidance of such additional components.

[0048] According to at least one embodiment:

[0049] - the first connecting element is arranged on a first carrier module part and the second connecting element is arranged on a second carrier module part; or

[0050] - the first connecting element is arranged on a first carrier module part and the second connecting element is arranged on a cross element; or

[0051] - the second connecting element is arranged on a first carrier module part and the first connecting element is arranged on a cross element.

[0052] An advantage of the above designs is that they provide secure and quick connection options for various support module components and / or a cross connector. This allows for scaffolding components that can be assembled quickly and safely.

[0053] According to a second aspect, a cross element for a support of a structural device has a substantially quadrangular shape. A first and / or second connecting element according to the first aspect or according to any desired embodiment of the first aspect is arranged on at least one side part, in particular on at least two side parts, of the cross element. Advantages and embodiments of the cross element correspond substantially to those of the connecting device described above. For the sake of a clear description, these are not repeated here, but apply accordingly.

[0054] According to at least one advantageous embodiment, the cross element comprises at least one connection for at least one vertical strut of the structural device.

[0055] According to at least one embodiment, the cross element has a first flange and a second flange on a side part on which a first or second connecting element is arranged, wherein the at least one first or at least one second receiving device each comprises at least one opening in the first flange and in the second flange.

[0056] An advantage here is that a stable and easy-to-manufacture at least one first or second receiving device is provided.

[0057] According to at least one embodiment, the cross element comprises at least one third receiving device for receiving at least one third securing element in at least one corner region.

[0058] One advantage here is that it provides a simple and secure fastening option for additional components, for example pivoting components such as joint connections and / or

[0059] Crane boom consoles are provided. According to a third aspect, a support module part for a support of a structural device comprises the first connecting element and / or the second connecting element according to the first aspect or according to any embodiment of the first aspect.

[0060] The advantages and configurations of the support module component essentially correspond to those of the connecting device and the cross element described above. For the sake of clarity, these are not repeated here, but apply accordingly.

[0061] According to at least one embodiment, the carrier module part comprises the first connecting element and the second connecting element, wherein the first connecting element is arranged at a first end region of the carrier module part and the second connecting element is arranged at a second end region of the carrier module part facing away from the first end region.

[0062] One advantage of this is that it allows for any desired modular combination of support module parts. Any number of such support module parts can be connected to one another by always bringing the side with the first connecting element together with the side with the second connecting element of the next support module part.

[0063] According to at least one embodiment, the carrier module part comprises an upper belt, a middle belt, a lower belt, and a connecting part, wherein the at least one first or at least one second receiving device is arranged on the upper belt and / or on the middle belt, wherein the first or second stop element extends over the upper belt, the middle belt, and the lower belt, and wherein the connecting part connects the upper belt, the middle belt, and the lower belt to one another.

[0064] The advantage here is that the lower chord is not interrupted by support devices, and no securing elements are installed in the area of ​​the lower chord. Thus, the lower chord forms a homogeneous, continuous component on which additional elements, such as a trolley, a roller carriage, or other movable element, can be guided.

[0065] According to at least one embodiment, the carrier module part further comprises an additional belt which is arranged on a side of the upper belt facing away from the middle and lower belt.

[0066] One advantage here is that the additional belt creates an additional area that is uninterrupted by any support devices or securing elements. This area of ​​the additional belt can also be used as a running surface for additional elements, such as another trolley, roller carriage, or other movable element.

[0067] According to at least one advantageous embodiment, the carrier module part is designed in a region of the lower belt and / or the additional belt to guide a running element.

[0068] Such a running element is, for example, a trolley, a roller carriage, or another corresponding element which can be guided and displaced on the support module part in the region of the lower chord. According to at least one embodiment, the support module part is at least partially double-walled, wherein in particular the support module part is double-walled in a region between the upper chord and the middle chord and / or in a region between the middle chord and the lower chord. In particular, the above-mentioned connecting part, which is at least partially double-walled, is arranged in at least one of these regions of the support module part.

[0069] One advantage here is that the stability and thus the load-bearing capacity of the support module part is increased by the double-walled design.

[0070] According to a fourth aspect, a support for a structural device comprises at least one cross element according to the second aspect or according to any embodiment of the second aspect. The support further comprises at least one support module part according to the third aspect or according to any embodiment of the third aspect. The at least one cross element is connected to at least one support module part by means of the connecting device according to the first aspect or according to any embodiment of the first aspect, and / or the at least one support module part is connected to at least one further support module part by means of the connecting device according to the first aspect or according to any embodiment of the first aspect.

[0071] The advantages and features of this carrier correspond to

[0072] Essentially those of the above-described

[0073] Connecting device, the cross element, and the support module part. For the sake of clarity, these are not repeated here, but apply accordingly.

[0074] According to a fifth aspect, a support for a structural device comprises at least one first support module part according to the third aspect or according to any embodiment of the third aspect. The support further comprises at least one second support module part according to the third aspect or according to any embodiment of the third aspect.

[0075] The advantages and features of this carrier are essentially the same as those of the connecting device and the carrier module described above. For the sake of clarity, these are not repeated here, but apply accordingly.

[0076] Further advantageous embodiments are disclosed in the attached figures and the following description. Elements with essentially the same function are given the same reference symbols in the figures, but need not be identical in all details.

[0097] Figures 12 to 19 show cross sections through support module parts according to various embodiments.

[0098] Figure 1 shows a perspective side view of a connecting device 1 for a support of a construction device, for example, a scaffolding system or a crane system, according to an exemplary embodiment. Figure 2 shows this connecting device 1 in a perspective top view.

[0099] The connecting device 1 comprises a first connecting element 2 and a second connecting element 3. The first connecting element 2 has a first stop element 4, which is located on a side of the first connecting element 2 facing the second connecting element 3. The second connecting element 3 has a second stop element 5, which is located on a side of the second connecting element 3 facing the first connecting element 2. The first and second stop elements 4, 5 each have stop surfaces with which the connecting elements 2, 3 abut one another when they are connected to one another.

[0100] In this exemplary embodiment, the first stop element 4 of the first connecting element 2 has a fitting piece 6 that protrudes toward the second connecting element 3. In the exemplary embodiment shown here, the fitting piece 6 has a substantially rectangular shape. Alternatively, the fitting piece 6 could also have a different square or other polygonal shape.

[0101] The second stop element 5 of the second connecting element 3 has in this embodiment a recess 7 which has an opening facing the first connecting element 2. In the embodiment shown here, the recess 7 has a substantially rectangular shape. Alternatively, the recess 7 could also have a different quadrangular or other polygonal shape. In particular, the fitting piece 6 and the recess 7 have corresponding shapes, so that the fitting piece 6 engages in the recess 7 when the stop elements 4, 5 of the first and second connecting elements 2, 3 abut one another. In the embodiment shown here, the fitting piece 6 and the recess 7 are designed such that they form a positive connection when they engage with one another.

[0102] Furthermore, in the exemplary embodiment shown here, the first connecting element 2 comprises two first receiving devices 8, each for a first bolt 9. The second connecting element 3 comprises two second receiving devices 10 for the two first bolts 9. The two first receiving devices 8 each comprise two first fastening tabs 11, i.e. a total of four first fastening tabs 11. The first fastening tabs 11 each have a first opening 12. The two first receiving devices 8 are arranged parallel to one another, i.e. they are arranged next to one another in such a way that the two first bolts 9 can be inserted parallel to one another into the two first receiving devices 8. The first openings 12 of the two first fastening tabs 11, which each belong to a first receiving device 8, are arranged concentrically to one another so that a first bolt 9 can be inserted into each first receiving device 8.The corresponding first fastening tabs 11 of a first receiving device 8 are arranged one above the other.

[0103] The two second receiving devices 10 each comprise two second fastening tabs 13, i.e., a total of four second fastening tabs 13. The second fastening tabs 13 each have a second opening 14. The two second receiving devices 10 are also arranged parallel to one another. The arrangement of the second fastening tabs 13 and the second openings 14 corresponds to the above-described arrangement of the first fastening tabs 11 and the first openings 12.

[0104] The first fastening tabs 11 and the second fastening tabs 13 are arranged offset from one another with respect to an insertion direction of the first bolts 9, so that the first and second fastening tabs 11, 13 lie above or below one another when the first connecting element 2 is connected to the second connecting element 3.

[0105] A first fastening tab 11 of each of the two first receiving devices 8 is arranged in a first edge region RI of the first stop element 4. Correspondingly, a second fastening tab 13 of each of the two second receiving devices 10 is arranged in a first edge region RI of the second stop element 5. The two further first fastening tabs 11 of the two first receiving devices 8 are arranged in a central region M of the first stop element 4. The two further second fastening tabs 13 of the two second receiving devices 10 are arranged in a central region M of the second stop element 5.

[0106] In a second edge region R2 of the first or second stop element 4, 5, opposite the first edge region RI, no fastening tab is arranged. Accordingly, no bolt is arranged in these second edge regions R2. The length of the first bolts 9 is selected such that they can connect the respective fastening tabs 11, 13 in the first edge region RI and the central region M to one another without extending into the second edge regions R2, i.e., in particular, they do not extend to a lower end of the stop elements 4, 5.

[0107] The fitting piece 6 described above and the recess 7 are arranged essentially centrally between the central region M and the first edge region RI in the exemplary embodiment shown here. This has the advantage that the connection between the fitting piece 6 and the recess 7 lies in a region in which the first bolts 9 fasten the first connecting element 2 and the second connecting element 3 to one another. Thus, in particular in this region of the engagement of the fitting piece 6 and the recess 7, lateral fixation is provided which reduces the risk of tipping or twisting. Alternatively, the fitting piece 6 and the recess 7 could also be arranged in a different region.

[0108] A first tapered region 15 is formed between each of the first fastening tabs 11, which are arranged parallel and next to one another. These first tapered regions 15 are arranged centrally between each of the first fastening tabs 11, which are arranged parallel and next to one another, and open in the direction of the second stop element 5. A second tapered region 16 is formed between each of the second fastening tabs 13, which are arranged parallel and next to one another. These second tapered regions 16 are arranged centrally between each of the second fastening tabs 13, which are arranged parallel and next to one another, and open in the direction of the first stop element 4.

[0109] The first tapered regions 15 each receive a part of the second stop element 5 when the two connecting elements 2, 3 are brought together. The second tapered regions 16 each receive a part of the first stop element 4 when the two connecting elements 2, 3 are brought together. The reception of a part of the first stop element 4 by the second tapered regions 16 can be seen in particular in Figure 2. In order to be able to see this better, the first fastening tabs 11 of the first edge region RI of the first connecting element 2 have been omitted in Figure 2. However, this only serves to improve the illustration and better understanding. The reception of a part of the second stop element 5 by the first tapered regions 15 is designed accordingly.

[0110] In the embodiment shown here, securing rings 20 are attached to the first bolts 9, by means of which the first bolts 9 can be secured in the respective receiving devices 8, 10.

[0111] Figure 3 shows a perspective side view of a first support module part 17 and a second support module part 18 for a support of a structural device according to an exemplary embodiment. The first support module part 17 is connected to the second support module part 18 by means of a connecting device 1, as described, for example, in Figures 1 and 2. Details of the connecting device 1, which have already been described above, will not be discussed again here; however, they nevertheless apply accordingly.

[0112] The first carrier module part 17 has, in a first end region E1 facing the connecting device 1, the first connecting element 2 described in detail above. In a second end region E2 of the first carrier module part 17 facing away from the first end region E1, the first carrier module part 17 has a second connecting element 3 corresponding to the second connecting element 3 described above. In this way, further first carrier module parts 17 can be attached to the second end region of the first carrier module part 17.

[0113] An upper flange 21 is arranged on an upper side of the first support module part 17, on which the first edge region RI is also located. The upper flange 21 forms a surface perpendicular to the stop elements 4, 5. In the end regions E1, E2 of the first support module part 17, the respective fastening tabs 11, 13 in the first edge region RI are formed as parts of the upper flange 21.

[0114] A lower flange 22 is arranged on an underside of the first support element 17 facing away from the upper side, on which the second edge region R2 is also located. The lower flange 22 also forms a surface perpendicular to the stop elements 4, 5, but in this exemplary embodiment has a smaller width than the upper flange 21. No fastening tabs are arranged on the lower flange 22 on the first support module part 17.

[0115] A central belt 23 is arranged on the first support module part 17 between the upper belt 21 and the lower belt 22. The central belt 23 extends parallel to the upper belt 21 laterally on the first support module part 17. In the end regions E1, E2 of the first support module part 17, the respective fastening tabs 11, 13 in the central region M are formed as parts of the central belt 23.

[0116] In order to realize the above-described offset of the first fastening tabs 11 and the second fastening tabs 13, a step 24 is arranged in the upper chord 21 and the middle chord 23.

[0117] The second carrier module part 18 has, in a first end region E1 facing the connecting device 1, the second connecting element 3 described in detail above. In a second end region E2 of the second carrier module part 18 facing away from the first end region E1, the second carrier module part has a differently designed second connecting element 3, by means of which the second carrier module part can be fastened to a cross element (not shown here). This differently designed second connecting element 3 likewise has second fastening tabs 13, a second stop element 5, and a recess 7, which are described in more detail with reference to the following figures.

[0118] On an upper side of the second support module part 18, on which the first edge region RI is also located, an upper flange 21 is also arranged. The upper flange 21 of the second support module part 18 also forms a surface perpendicular to the second stop elements 5, but without the previously described gradation. In the end regions E1, E2 of the second support module part 18, the respective fastening tabs 13 in the first edge region RI are formed as parts of the upper flange 21.

[0119] A lower chord 22 is also arranged on an underside of the first support element 17 facing away from the upper side, on which underside the second stop element 5 is also located. The lower chord 22 also forms a surface which is perpendicular to the first stop elements 4, but in this exemplary embodiment has a smaller width than the upper chord 21. The lower chord 22 of the second support module part 18 forms the lower second fastening tabs 13 in the second end region E2. In this case, the lower second fastening tabs 13 are therefore not arranged in the central region M, but in the second edge region R2 of the second stop element 5.

[0120] The second carrier module part 18 has no continuous

[0121] Center chord. Openings 25 are arranged below the upper chord 21 in both support module parts 17, 18. These openings 25 are provided, for example, for lifting the support module parts 17, 18 by means of a crane.

[0122] Figure 4 shows a perspective side view of a cross element 26 and a second support module part 18 for a support of a structural device according to an exemplary embodiment. The second support module part 18 essentially corresponds to the previously described second support module part 18, as shown in Figure 3, although the first end region has been omitted for the sake of clarity.

[0123] Figure 4 shows a fastening of the second support module part 18 to the cross element 26. The second support module part 18 has, as described above, a second connecting element 3 with a second stop element 5 and a recess 7.

[0124] In the exemplary embodiment shown here, the cross element 26 has a connection 19 for a vertical strut (not shown here) of a structural device. Alternatively, the cross element 26 can also be designed solely for connecting support elements lying in one plane.

[0125] The cross element 26 has a first connecting element 2 on a side facing the second support element 18. This first connecting element 2 of the cross element 26 also has a first stop element 4 with a fitting piece 6. The following will focus in particular on differences from the previously described elements. Analogous embodiments are not repeated for the sake of clarity of description.

[0126] In this exemplary embodiment, the fitting piece 6 and the recess 7 are arranged centrally with respect to a main extension direction of the stop surfaces of the first and second stop elements 4, 5. The second fastening tabs 13 of the second support module part 18 are arranged, as explained above, on the upper chord 21 and on the lower chord 22.

[0127] The cross element 26 also has first receiving devices 8 for first bolts 9, which are used to connect the second carrier module part 18 and the cross element 26. In the exemplary embodiment shown here, these first receiving devices 8 comprise a first flange 27 on an upper side of the cross element 26 and a second flange 28 on an underside of the cross element 26. Openings 29, which are provided for receiving the first bolts 9, are arranged in the first flange 27 and in the second flange 28. When the second carrier module part 18 is attached to the first connecting element 2 of the cross element 26 and the first bolts 9 are inserted into the openings 29 on the flanges 27, 28 of the cross element 26 and the second openings 14 of the second fastening tabs 13 on the second carrier module part 18, the second carrier module part 18 is fixed to the cross element 26.

[0128] In the exemplary embodiment shown here, second bolts 30 are also attached to the first bolt 9, which facilitate handling of the first bolt 9 and lock the first bolt 9 to the upper flange 27. In the exemplary embodiment shown here, a first connecting element 2 with the fitting piece 6 is attached to the cross element 26, and a second connecting element 3 with the recess 7 is attached to the second carrier module part 18. Alternatively, these can of course also be interchanged, so that a recess 7 would be arranged on the cross element 26, and a fitting piece 6 on the second carrier module part 18.

[0129] On another side wall of the cross element 26, a further first connecting element 2 can also be seen, to which a carrier module part can also be attached. Further corresponding first and / or second connecting elements can be attached analogously to the side walls of the cross element 26 (not visible here).

[0130] Such an arrangement with a total of four first connecting elements 2 on a cross element 26 is shown in Figures 5 and 6. Figure 5 shows a perspective side view of such a cross element 26, and Figure 6 shows a plan view of such a cross element.

[0131] In the embodiment according to Figure 5, two second carrier module parts 18, as described in detail above, are attached to the cross element 26, as also described in detail above.

[0132] In addition, two double-T beams 31 are attached to the cross element 26. For this purpose, the double-T beams 31 also have second connecting elements 3 at the ends facing the cross element 26, which second connecting elements 3 essentially correspond to the second connecting elements 3 by means of which the second carrier module parts 18 are fastened to the cross element 26. In particular, the shape of the second fastening tabs 13, by means of which the double-T beams 31 are fastened to the cross element 26, can differ slightly from those described above, but their function is the same. In particular, all of the second fastening tabs 13 arranged parallel and next to one another have a second tapered region 16, as described in detail above. This can be seen in particular in Figure 6.

[0133] In the illustration according to Figure 6, a second support module part 18 is arranged on the cross element 26, as well as two double-T beams 31 of different widths. Furthermore, a beam configured, for example, as a profile tube 32 is attached to the cross element 26.

[0134] In order to be able to fasten the double-T beams 31 and the profile tube 32 to the cross element 26 with the first connecting elements 2 described above, fastening attachments 33 are attached to the ends of the double-T beams 31 and the profile tube 32 facing the cross element 26, each of which has a second connecting element 3 according to the embodiments described above for attachment to the cross element 26. In this way, any type of beam can be fastened to the cross element 26 without the entire beams having to be specially designed for this purpose.

[0135] Figures 7, 8A, and 8B further show a further possible use of the previously described cross element 26. Figure 7 shows a perspective side view of the cross element 26 with a pivotable suspension 34 attached to the cross element 26. Figure 8A shows a side view and Figure 8B a top view of the cross element 26 with a pivot arm 35.

[0136] For this purpose, the cross element has further openings 29 in the first flange 27 and the second flange 28 in corner regions K. These further openings 29 are suitable for receiving further bolts 9. By means of these further bolts 9, the pivotable suspension 34 is fastened to the cross element 26 in the embodiment according to Figure 7 and the pivot arm 35 is fastened in the embodiment according to Figures 8A and 8B.

[0137] Figures 9, 10, and 11 show three exemplary embodiments of supports 36 for structural devices. The figures each show, in particular, a perspective side view of a portion of these supports.

[0138] Figure 9 shows an exemplary embodiment in which a second carrier module part 18 is fastened to one side of a cross element 26, and a fastening of a first carrier module part 17 is shown on a side of the second carrier module part 18 facing away from the cross element 26. The cross element 26 essentially corresponds to the cross elements 26 described above, for example as described with reference to Figure 4. The first and second carrier module parts 17, 18 essentially correspond to the first and second carrier module parts 17, 18 described above, for example as described with reference to Figures 3 and 4.

[0139] Figure 10 shows an embodiment in which the carrier 36, as shown in Figure 9, has been extended by a further first carrier module part 17', a third carrier module part 37 and a fourth carrier module part 38. Figure 10 shows an exploded view of the respective

[0140] Carrier module parts 17 , 17 ' , 18 , 37 , 38 .

[0141] The further first support module part 17' is arranged on a side of the first support module part 17 facing away from the second support module part 18. The further first support module part 17' is configured identically to the first support module part 17 and is connected to the first support module part 17 according to the connecting devices 1 described above.

[0142] The third support module part 37 is arranged on a side of the further first support module part 17' facing away from the first support module part 17. The third support module part 37 has the same elements as the first support module part 17, but has a smaller extent in the direction of a main extension direction H of the support 36 than the first support module part 17. The third support module part 37 is connected to the further first support module part 17' according to the connecting devices 1 described above.

[0143] The fourth support module part 38 is arranged on a side of the third support module part 37 facing away from the further first support module part 17'. The fourth support module part 38 has, on a side facing the third support module part 37, i.e. in a first end region E1, the same elements as the first support module part 17, in particular a first connecting element 2 described in detail above. The fourth support module part 38 is connected to the third support module part 37 according to the connecting devices 1 described above. However, the fourth support module part 38 represents one end of the support 36 and has no further connecting element 2, 3 in a second end region E2. Instead, in the second end region E2 of the fourth support module part 38, the upper chord 21 is designed as a sloping flank 39.

[0144] Figure 11 shows an embodiment in which the support 36 has a cross element 26, as described above, on which the sequence of support module parts 17, 17', 18, 37, 38 shown in Figure 10 is arranged twice. Each of these sequences of support module parts 17, 17', 18, 37, 38 is attached to adjacent sides of the cross element 26. Figure 11 shows this arrangement in an assembled form.

[0145] On the remaining two sides of the cross element 26, on which further first connecting elements 2 are arranged, double T-beams 31, as described for example with reference to Figures 5 and 6, are fastened.

[0146] Figure 11 further shows that in a lower region of the rows of support module parts 17, 17', 18, 37, 38, in which the lower chord 22 is located, no interruptions by fastening straps or bolts are provided. Thus, trolleys 40 can be guided in this region, one of which is shown here on each row of support module parts 17, 17', 18, 37, 38. The trolleys 40 are movable crane components which, for example, as shown here, can be used to change the position of a hoist rope. The trolleys 40 have, for example, deflection pulleys for a hoist rope. Trolleys 40 can be moved along the support 36 on the respective part of the support 36 to which they are attached. As an alternative to the exemplary embodiments of supports 36 shown here, a support can also be designed without a cross element, for example having at least two of the support module parts described above.

[0147] Figures 12 to 19 show cross-sections through carrier module parts 41 according to various embodiments. The carrier module parts described in these Figures 12 to 19 can, for example, comprise the elements of each of the above-described carrier module parts 17, 17', 18, 37, 38, apart from the differences described here.

[0148] Figure 12 shows cross sections through a support module part 41, which has an upper chord 21, a center chord 23, and a lower chord 22. The previously described fastening tabs are formed here in the upper chord 21 and the center chord 23, so that the first bolts 9 are arranged between the upper chord 21 and the center chord 23. The lower chord 22 has a narrower extension than the upper chord 21 and the center chord 23 and is designed to guide a trolley 40 along the lower chord 22.

[0149] In this exemplary embodiment, the support module part 41 has a single-walled connecting part 42, which connects the upper chord 21, the lower chord 22, and the center chord 23. The support module part 41 shown here thus essentially corresponds in cross-section to the previously described support module parts 17, 17', 37, 38.

[0150] Figure 13 shows cross sections through a support module part 41, which has an upper chord 21, a middle chord 23, and a lower chord 22. The previously described fastening tabs are formed here in the upper chord 21 and the middle chord 23, so that the first bolts 9 are arranged between the upper chord 21 and the middle chord 23. The lower chord 22 has a narrower extension than the upper chord 21 and the middle chord 23, and is designed so that a trolley 40 is guided on the lower chord 22. Alternatively or in addition to the trolley 40 shown here, any other displaceable element could also be used. This applies accordingly to all subsequent figures which show such a trolley 40.

[0151] In this exemplary embodiment, the support module part 41 has a partially double-walled connecting part 42. In a region between the upper chord 21 and the central chord 23, the connecting part 42 is double-walled, which further increases stability in this region. In a region between the lower chord 22 and the central chord 23, the connecting part 42 is single-walled.

[0152] In this exemplary embodiment, the previously described fitting piece and the previously described recess can be arranged in the region between the central chord 23 and the upper chord 21, or in the region between the central chord 23 and the lower chord 22, or in both of these regions. In particular, when the fitting piece and / or recess is arranged in the region with the double-walled connecting part 42, a connecting element can have a fitting piece or a recess on only one wall of this double wall, or one on each of the two walls of this double wall. It is also possible for a connecting element that is arranged in the region of a double-walled connecting part 42 to have a fitting piece on one of these walls and a recess on the other wall. This applies accordingly to all subsequent figures that show cross-sections of support module parts.

[0153] Figure 14 shows cross sections through a support module part 41, which has an upper chord 21, a central chord 23, and a lower chord 22. The previously described fastening tabs are formed here in the upper chord 21 and the central chord 23, so that the first bolts 9 are arranged between the upper chord 21 and the central chord 23. The lower chord 22 has a narrower extension than the upper chord 21 and the central chord 23, and is designed so that a trolley 40 is guided on the lower chord 22.

[0154] In this exemplary embodiment, the support module part 41 has a double-walled connecting part 42. The connecting part 42 is double-walled over the entire area between the upper chord 21 and the lower chord 22, which further increases stability.

[0155] Figure 15 shows cross sections through a carrier module part 41, which has an upper chord 21, a middle chord 23, a lower chord 22, and an additional chord 43. The previously described fastening tabs are here in the upper chord

[0156] 21 and the middle chord 23 , so that the first bolts 9 are arranged between the upper chord 21 and the middle chord 23 . The additional chord 43 is attached to a lower chord

[0157] 22 opposite side of the upper chord 21. The lower chord 22 and the additional chord 43 each have a narrower extension than the upper chord 21 and the middle chord

[0158] 23 , and are both designed so that a trolley 40 is guided on the lower belt 22 and on the additional belt 43 .

[0159] In this exemplary embodiment, the support module part 41 has a single-walled connecting part 42 over the entire area between the lower chord 22 and the additional chord 43.

[0160] In this or all subsequent embodiments showing an additional belt 43, alternatively or in addition to the above-explained arrangement of fitting piece and / or recess, a corresponding fitting piece and / or recess can also be arranged in the area between the upper belt 21 and the additional belt 43.

[0161] Figure 16 shows cross sections through a carrier module part 41, which has an upper chord 21, a middle chord 23, a lower chord 22, and an additional chord 43. The previously described fastening tabs are here in the upper chord

[0162] 21 and the middle chord 23 , so that the first bolts 9 are arranged between the upper chord 21 and the middle chord 23 . The additional chord 43 is attached to a lower chord

[0163] 22 opposite side of the upper chord 21. The lower chord 22 and the additional chord 43 each have a narrower extension than the upper chord 21 and the middle chord

[0164] 23 , and are both designed so that a roller carriage 44 is guided on the lower belt 22 and on the additional belt 43 . In the exemplary embodiment shown here, the roller carriages 44 have a design which requires less space in the vertical direction than the previously described trolleys 40 . In the exemplary embodiment shown here, a distance between the additional belt 43 and the upper belt 21 is therefore smaller than a distance between the lower belt 22 and the middle belt 23 . The distance between the lower belt 22 and the middle belt 23 could also be designed to be smaller.

[0165] In this exemplary embodiment, the support module part 41 has a single-walled connecting part 42 over the entire area between the lower chord 22 and the additional chord 43.

[0166] Figure 17 essentially shows the cross sections of the carrier module part 41 according to Figure 16, wherein in Figure 17, however, the trolley 40 according to the embodiment of Figures 12 to 15 is attached to the lower belt 22, and the roller carriage 44 according to the embodiment of Figure 16 is attached to the additional belt 43.

[0167] Figures 18 and 19 show cross-sections of further embodiments of support module parts 41. Figure 18 shows a support module part 41 in which the upper chord 21 and the central chord 23 are formed by opposite sides of a profile tube. The lower chord 22, to which a trolley 40 is attached, is connected to the central chord 23 by means of a single-walled connecting part 42.

[0168] In the embodiment according to Figure 19, an additional belt 43, also with a trolley 40, is additionally fastened to the upper belt 21 by means of a single-walled connecting part 42.

[0169] The embodiments shown here in Figures 12 to 19 can be combined with one another in a suitable manner.

[0170] The carrier module parts and modularly constructed carriers described in this application can be used in particular in the German patent application entitled "Carrier element, work platform, climbing system, and method" filed by the same applicant on the same day as this application, the disclosure of which is incorporated herein by reference.
