Abstract

The invention relates to a device for the assembly and disassembly of trench boxes, characterized by two spaced-apart outer horizontal beams (1, 2) which are connected to each other by at least two connecting struts (3, 4, 5, 6), wherein at least two trench plate receptacles (8, 9) are arranged on each horizontal beam (1, 2), each of which is formed by two vertical beams (10, 11; 12, 13) arranged perpendicularly on the horizontal beams (1, 2).

Description

[0001] The invention relates to a device for the assembly and disassembly of installation boxes.

[0002] Shoring systems are used to secure trenches and excavations, as unshored trenches and excavations pose a potential hazard to workers. Shoring boxes are used for trench depths of up to approximately 4 to 6 meters, while for deeper trenches or excavations, a sliding rail shoring system is employed. With sliding rail shoring, each individual component is pushed into or pulled out of the trench or excavation separately and parallel to the other components. In contrast, a shoring box is pushed into or lowered into the trench or excavation as a single unit and then pulled out again. This means that the shoring boxes must be assembled before being pushed in or lowered. This assembly takes place directly on-site at the construction site.Therefore, in the present context, the term "shoring box" should be understood to mean all shoring systems that are placed into the excavation pit or trench as a whole and are also removed from it as a whole.

[0003] A trench box essentially consists of two trench shoring panels arranged parallel to each other, held apart at their ends by two spacers, preferably spindles, positioned at different heights. The trench box is assembled by first connecting one of the shoring panels to the spacers or spindles, and then, suspended freely, bringing the second shoring panel into position using a crane or excavator. The second shoring panel is then also connected to the spacers or spindles. Because the second shoring panel is suspended freely from the crane or excavator, it can be unintentionally moved by external influences, such as wind, or by the movements of the installers, potentially causing injury to the operator or other installers.Furthermore, the free movement of the second shoring plate on the crane or excavator makes it more difficult to correctly position the second shoring plate relative to the spacers or spindles with which it is to be connected.

[0004] DE 199 03 520 A1 shows a device for mounting installation boxes.

[0005] It is therefore an object of the invention to provide a device for the assembly and disassembly of trench boxes which ensures easy assembly and disassembly of trench boxes, and which also reduces the risk of injury to the personnel carrying out the assembly or disassembly.

[0006] This problem is solved by a device for assembling and disassembling installation boxes with all the features of claim 1. Advantageous embodiments of the invention are found in the dependent claims.

[0007] The device according to the invention for the assembly and disassembly of trench boxes is characterized in that two external horizontal beams are connected to each other by at least two connecting struts, wherein at least two trench plate receptacles are arranged on each horizontal beam, each of which is formed by two vertical beams arranged perpendicularly on the horizontal beams.

[0008] The device according to the invention for assembling and disassembling trench boxes ensures in a simple manner that the two trench box panels can be easily inserted into the trench box panel receptacles of the device according to the invention, so that they are arranged parallel to each other at the desired distance, without being able to perform unintended movements during the further assembly of the spacers or spindles that could lead to injuries to personnel. It is important to note that the trench box panels have sufficient play in the trench box panel receptacles to allow for easy connection of the spacers or spindles to the trench box panels.To connect the spacers or spindles to the trench shoring panels, corresponding connecting elements are usually arranged on the shoring panels. The heads of the spacers or spindles can be inserted into these elements and secured with a bolt, thus fixing them firmly to the respective shoring panel. Of course, other connecting elements besides a locking bolt are also conceivable for connecting the spacers or spindles to the shoring panels. However, it is within the expertise of a qualified professional to use appropriate connections.

[0009] After the individual elements of the trench box have been assembled in the device according to the invention, the entire trench box can now be lifted out of the device and lowered into the designated trench or excavation. As is already known from the prior art, a crane or excavator is used for this purpose, which lifts the installed box by means of chains that can be attached to the respective ends of the trench shoring panels and lowers it into the trench or excavation, pressing it in if necessary. However, other devices, such as trench box grabs equipped with a hydraulic system, can also lift the assembled trench box as a whole and place it into the trench or excavation.

[0010] The dismantling of a trench box now proceeds in reverse order. The trench box is lifted out of the trench or excavation using an excavator or crane and inserted into the device according to the invention, in which the trench shoring panels are again inserted into the trench shoring panel receptacles of the device according to the invention. After the chains for removing the trench box from the excavation or trench have been removed from the ends of the trench shoring panels, the spacers or spindles can now be detached from the two trench shoring panels and stowed away, and subsequently the two trench shoring panels can be easily removed from the device according to the invention and set aside.

[0011] The device according to the invention not only provides a simple method for assembling and disassembling trench boxes that minimizes the risk of injury, but also achieves time savings during assembly and disassembly by ensuring the secure and immobile arrangement of the trench boxes relative to one another, thus optimizing workflows on site.

[0012] According to a first advantageous embodiment of the invention, the vertical supports forming a trench sheet receptacle have different lengths or heights, with the shorter vertical support preferably having a chamfer or rounded end relative to the longer vertical support. Such an embodiment of the device according to the invention for assembling and disassembling trench sheet boxes ensures easy insertion of trench sheets into the trench sheet receptacles. The trench sheets do not need to be inserted exactly perpendicularly into the trench sheet receptacle, but can be inserted via the chamfers or rounded ends of the shorter vertical supports in such a way that they automatically slide or glide into the respective trench sheet receptacles, without the need for installation personnel to insert the trench sheets exactly perpendicularly into the trench sheet receptacles.It is sufficient for the trench shoring panels to be brought up to the chamfers or rounded edges and then be able to slide into the shoring panel receptacles. This ensures that the width of the shoring panel receptacles can be designed to be only minimally larger than the width of the shoring panels themselves, so that the shoring panels have very little play in the receptacles, which is necessary to easily and precisely connect the spacers or spindles to the shoring panels.

[0013] In a further advantageous embodiment, a trench sheet holder is fixedly positioned on each horizontal beam. This embodiment of the invention allows the fixed trench sheet holder to also have an additional connecting strut in its upper region, which contributes to stabilizing the entire device according to the invention. Furthermore, the rigidity can be increased again by support struts arranged on the vertical beams of the fixed trench sheet holder, which are also connected to the respective horizontal beam. This embodiment of the invention also makes it possible to easily vary the spacing of the trench sheets by simply positioning and then fixing a trench sheet holder variably on the device according to the invention for the assembly and disassembly of trench sheet boxes.

[0014] In a further embodiment of the invention, at least one shoring plate holder can be variably positioned and fixed on the respective horizontal support. This allows for easy adjustment of the desired spacing of the shoring plates, which must be adapted to the respective excavation or trench width at the construction site. Of course, it is also possible for both shoring plate holders to be variably positioned and fixed on the device according to the invention, so that the desired width of the shoring box can be adjusted by appropriately positioning the two shoring plate holders.

[0015] The at least two horizontal beams are connected to each other by at least three, preferably four, connecting struts. This embodiment of the invention ensures even greater stability and strength of the device according to the invention.

[0016] According to a particularly advantageous embodiment of the invention, the horizontal supports and the at least two connecting struts are made of metal, preferably steel, and are joined together, preferably welded together. The metal construction of the individual elements of the device according to the invention, preferably steel, ensures a particularly high stability and strength of the device, which is also desirable for the demands and loads in the civil engineering industry, so that the device according to the invention achieves an economically viable service life.

[0017] The embodiment of the inventions aims in the same direction by providing a further horizontal beam between the two outer horizontal beams, which is also connected to the at least two connecting struts. Preferably, this further horizontal beam is also made of metal, preferably steel, so that the connection or joining of this further horizontal beam to the at least two connecting struts is also possible by welding. It is fundamentally advantageous that all individual parts of the device according to the invention are made of the same material, preferably a metal, particularly preferably steel, since the individual parts can then be easily connected or joined using the same welding process.

[0018] However, it is also possible that the device according to the invention, or its individual parts, consist of different materials and that the individual parts are joined using other joining methods, such as screwing and the like. Screwing, for example, could be advantageous in that the connection can be easily loosened, and the device according to the invention can be disassembled into its individual parts, thus enabling space-saving transport of the device to and from the construction site.

[0019] In a further particularly advantageous embodiment of the invention, a spindle adjustment device is arranged on the apparatus for assembling and disassembling trench boxes. This makes it possible to fix a spindle, which connects the two trench box panels, in the spindle adjustment device of the apparatus according to the invention and to adjust it to the desired length, which corresponds to the width of the trench box. This ensures that a single installer can easily adjust the spindle to the desired length, which corresponds to the width of the trench box, without having to fix the spindle head during the adjustment process and manually extend or retract the spindle to the corresponding length.

[0020] By fixing the spindle in the spindle adjustment device, a single technician can easily adjust the spindle length. Advantageously, the spindle adjustment device is provided with a spindle head mount for the rotationally fixed mounting of a spindle head and at least one spindle mount for the rotatable mounting of a spindle. The spindle head can thus be fixed rotationally in the spindle head mount by the technician, while the spindle itself rests rotatably on the spindle mount, allowing the technician to easily adjust it to the desired length by rotating the spindle.

[0021] Further objectives, advantages, features, and applications of the present invention will become apparent from the following description of exemplary embodiments with reference to the drawings. All features described and / or illustrated, individually or in any meaningful combination, constitute the subject matter of the present invention, even independently of their compilation in the claims or their cross-references.

[0022] They show: Fig. 1a to c: an exemplary schematic representation of a storage box in a view from above, from the front and from the side, Fig. 2a and b: a first embodiment of a device according to the invention in a view from above and from the side as well as Fig. 3a and b: a second embodiment of a device according to the invention in a view from above and from the side.

[0023] In the Fig. Figures 1a to 1c schematically show an embodiment of a construction box 100 in various views. Fig. 1a a view from above, Fig. 1b a view from the front and Fig. Figure 1c shows a side view. The device according to the invention is designed for the assembly and disassembly of such trench boxes 100. Such trench boxes 100 consist of two spaced-apart trench panels 101 and 102 arranged substantially parallel to each other, which in this case are connected to each other by spindles 103 and 104. The spindles 103 and 104 are detachably connected to the trench panels. In the present embodiment, the spindles 103 and 104 are arranged at different heights at the ends of the trench panels 101 and 102.

[0024] In the Fig. Figure 2 shows a first embodiment of a device according to the invention for mounting and dismounting installation boxes in various views. Fig. 2a) the device according to the invention in a top view, while Fig. 2b) the device according to the invention is shown in a side view.

[0025] The exemplary embodiment of the Fig. The structure consists of a steel frame in which three connecting struts 3, 4, and 6, designed as T-beams, are welded to two outer horizontal beams 1 and 2 above them, which are also designed as T-beams. In addition to the two outer horizontal beams 1 and 2, the connecting struts 3, 4, and 6 are welded to a further horizontal beam 7, also designed as a T-beam, located between the two outer horizontal beams 1 and 2. To further increase the stability of the entire structure, another connecting strut 5 is arranged between the two connecting struts 4 and 6, which is also welded to all three horizontal beams 1, 2, and 7.

[0026] On each of the outer horizontal beams 1 and 2, two trench sheet plate receptacles 8 and 9 are arranged. In the case of the first receptacle 8, these receptacles consist of vertical beams 10 and 11 welded perpendicularly to the horizontal beams 1 and 2. The vertical beam 11, which points towards the center of the horizontal beam 1, 2, is longer and / or taller than the vertical beam 10, which points towards the end of the horizontal beam 1, 2. The two vertical beams 10 and 11 are spaced apart such that they form the trench sheet plate receptacle 8, whereby a trench sheet held in it has very little play and is also arranged essentially perpendicular to the respective horizontal beam 1, 2. A support strut 19 is additionally welded to the vertical beam 10, which is welded to the horizontal beam 1, 2 at its other end.Similarly, the vertical support 11 has a support strut 20 welded to it, which is also welded to the horizontal support 1,2 at its other end. These support struts, in turn, serve to increase the stability and strength of the entire device. In the present embodiment, the vertical strut 11 is longer or taller than the vertical strut 10. The vertical strut 10 has a chamfer 14 at its open end, which is not welded to the horizontal support 1,2. This chamfer 14 allows a trench sheet to be easily inserted into the trench sheet receptacle 8 by sliding off it during insertion.This design facilitates the insertion of a trench sheet into the trench sheet receptacle 8, so that the trench sheet does not have to be inserted exactly into the trench sheet receptacle by the installer, but is merely brought to the chamfers so that it can then slide or slide into the trench sheet receptacle 8.

[0027] In the present embodiment, the vertical beams 10 welded onto the horizontal beams 1 and 2 are welded together again by means of a connecting strut 28, so that the stability of the device is also increased, in particular when inserting a trench sheet into the trench sheet receptacle 8.

[0028] To form the second trench shoring plate receptacle 9, round profiles 21, 22, 23, 24, and 25 are welded onto the horizontal beams 1 and 2. These round profiles 21 to 25 each have a through-hole (not shown) through which rectangular hollow beams in the form of vertical beams 12 and 13, which also have through-holes, can be placed or inserted over two of the round profiles 21 to 25 and connected and fixed to each other by means of a bolt and a spring clip (also not shown). The vertical beams 12 and 13 placed on top of these then form the second trench shoring plate receptacle 9. The vertical beams 12 are longer and / or taller than the vertical beams 13.The vertical beams 13 also have a chamfer 15 which is directed towards the vertical beams 12, so that a trench sheet can slide off here as well and can be easily inserted into the trench sheet receptacles 9.

[0029] In addition, further vertical beams 26, 27 and 30 are welded vertically to the end of the horizontal beams 1, 2 and 7 associated with the shoring plate receptacle 8. Further auxiliary devices can be arranged on these vertical beams, but these are not provided in this embodiment. Such an auxiliary device is shown in the embodiment of Fig. 3 shown in the form of a spindle adjusting device 16.

[0030] In this embodiment, the round profiles 21 to 25 can thus be used to Fig. Two different widths of a trench box can be set. In this embodiment, the steps are fixed with paired round profiles 21 and 22, 22 and 23, and 24 and 25. An embodiment with continuously adjustable trench box widths is shown in the following embodiment. Fig. 3, which will be described in more detail below.

[0031] To assemble a trench box, a trench sheet is first inserted into trench sheet receptacle 8 or 9. In the following step, another trench sheet is inserted into the other trench sheet receptacle 9 or 8. The trench sheets are now spaced at the desired distance in trench sheet receptacles 8 and 9 and are essentially parallel to each other, with sufficient clearance to easily connect spindles to the trench sheets. In a final step, spindles, pre-set to the appropriate width of the trench box, are connected to the trench sheets held in trench sheet receptacles 8 and 9 according to the manufacturer's instructions and as is known in the art. The connection between the spindles and the trench sheets is achieved via spindle heads, which are inserted into corresponding receptacles on the trench sheets and secured.Once all spindles have been connected and fixed to the trench shoring plates, the now fully assembled trench shoring box can be removed from the device for the assembly and disassembly of trench shoring boxes, preferably by means of an excavator or crane, and inserted or lowered into the designated excavation pit or trench in the usual manner.

[0032] The dismantling of the trench box is carried out in reverse order. After being removed from the excavation or trench, the entire trench box is inserted into the trench box assembly and dismantling device. As a first step, the spindles are loosened and removed according to the manufacturer's instructions, and finally, the trench sheets are removed from their respective sheet sheet holders 8 and 9. The trench sheets and spindles are then stored accordingly.

[0033] In the Fig. Figure 3 shows a second embodiment of a device according to the invention for mounting and dismounting storage boxes in various views. The figure shows... Fig. 3a) a view of this embodiment from above, while in the Fig. 3b) a side view of this embodiment is shown.

[0034] The exemplary embodiment of the Fig. 3 essentially corresponds to the embodiment of the Fig. 2, wherein in the present embodiment no fixed distances are provided for the trench sheet mounting 9 relative to the other trench sheet mounting 8. Rather, the trench sheet mounting 9 of this embodiment can be adjusted variably and continuously, since the vertical supports 12 and 13 forming the trench sheet mounting 9 can be moved on a rail system 29 on the respective horizontal supports 1 and 2, respectively, and the desired distance between one trench sheet mounting 9 and the other trench sheet mounting 8 is continuously adjustable. In this respect, it is also possible in this embodiment to continuously adjust the width of the trench sheet box. With the exception of this continuous adjustability of the trench sheet mounting 9, the trench sheet mounting 8 and 9 correspond to those of the trench sheet mounting 8 and 9 of the embodiment of Fig. 2. Therefore, with regard to the description of the building plate supports and the vertical struts 10 to 13 forming them, reference is made to the description of the Fig. 2 referred.

[0035] In addition to the function of receiving trench shoring panels in the trench shoring panel receptacles 8 and 9 for mounting a trench shoring box, this embodiment includes a spindle adjustment device 16. This spindle adjustment device 16 is arranged at the end of the horizontal beams 1, 2, and 7 associated with the trench shoring panel receptacle 8. The spindle adjustment device 16 forms a component already described in the previous section. Fig. 2. The spindle adjustment device 16 consists of a spindle head receptacle 17, which is arranged on the vertical beams 30 welded perpendicularly to the central horizontal beam 7. A spindle head can be fixed to the spindle head receptacle 17 in a rotationally fixed manner. After the spindle head is fixed in the spindle head receptacle 17, the spindle itself can be rotatably placed on a spindle receptacle 18 and adjusted or screwed into the desired length, which corresponds to the desired width of the installation box. The spindle receptacle 18 is arranged on and welded to a vertical strut 26, 27, with the vertical strut 26, 27 being welded to the respective outer horizontal beam 1 or 2 and standing perpendicular to it.

[0036] The assembly and disassembly of a trench box in this embodiment corresponds to the assembly and disassembly of a trench box as used in the Fig. 2 is already described.
