The rebar connections are bent out of the first structural element before the second structural element is arranged on the first structural element.

[0019] TECHNOLOGICAL BACKGROUND

[0020] Reinforcing steel is regularly used in the construction of concrete structures. In structures with multiple pours, reinforcing steel is cast into the first pour, and after hardening, the ends of the reinforcing steel are bent out of the space provided by a storage box located in the formwork, according to known practice. They then serve as joint or connection reinforcement in the area of ​​the joint between adjacent pours. This bending is carried out manually on the construction site by a worker or technician. This is strenuous and time-consuming, especially when the reinforcing steel to be bent has a diameter of more than 8 mm. This is where the invention comes in.

[0021] PRESENTATION OF THE INVENTION

[0022] Against this background, the object of the invention is to improve the handling of reinforcing steel. In particular, the reinforcement of concrete structures in the area of ​​construction joints between adjacent concrete sections is to be simplified and qualitatively improved, also taking into account safety on the construction site. According to claim 1, this object is achieved by a Thomas Notarfrancesco ' GSKH 26 February 2026

[0023] The stationary or mobile, manually operated, and in particular portable, device for gripping, fixing, bending, bending back, straightening, and / or cutting at least one reinforcing bar, as described above, is described below. The device is designed so that the working element can be actuated by a drive unit attachable to the working element. The device comprises at least one support element (counter-holder) with which a force and / or a torque transmitted from the drive unit to the working element, the reinforcing bar, or the storage box can be mechanically supported. In particular, the combination of support element and drive unit enables the reinforcing bar or the bending connection to be bent, straightened, or cut without requiring significant force.On construction sites, a large number of reinforcing bars regularly need to be bent (back), straightened, or cut to length. The device described and claimed herein (gripping, fixing, bending, bending back, straightening, and cutting) enables this to be done in a uniform and reproducible manner, not only on the construction site but also in manufacturing or workshops, provided the device is operated there in a stationary position. The device's modular design allows for flexible use. It is specifically designed for reinforcing bars with a diameter of approximately 6 mm to approximately 25 mm to accommodate the widest possible range of reinforcing bars.Manual bending / straightening of the reinforcing bars or connecting reinforcements is eliminated, thus also preventing any irregularities in the bending / straightening process that can arise from the involvement of individuals with varying levels of experience, or from fatigue or diminished physical strength of the workers manually preparing the reinforcing bars. A separate cutting device, for example to remove sharp burrs from the ends of the reinforcing bars or to cut the bars to the required length, is not necessary, as bending / straightening and cutting are possible with the device described herein. The device can also be used to bend / straighten / cut (metal, aluminum, stainless steel, plastic) profiles or tubes. It can also be used to create pre-bends, hook shapes, spirals, or other forms. T T h Thomas Notary f francesco GSKH February 26, 2026

[0024] Special bends. In addition to rebending, the device allows for the pre-bending of new reinforcement elements, including hooks, spirals, and special shapes. Angle bending can be up to 360°. Furthermore, the device can be used for bending pipes, aluminum profiles, stainless steel, and other malleable materials.

[0025] The handling of reinforcing steel is further improved by a device according to claim 2. Accordingly, a first and at least one further working element are provided, wherein at least one working element can be actuated by a drive unit attachable to the working element, and wherein at least one working element is formed as a support element with which a force and / or a torque transmitted from the drive unit to the working element or to the reinforcing steel can be mechanically supported. For example, two working elements can be provided, both rotatable about a common axis of rotation and both equipped with cutting blades. When the working elements are moved towards each other, a reinforcing steel arranged between the working elements can be cut. In this process, one working element forms a support element for the other working element.The torque or force of the device is transferred to both working elements and dissipated via the reinforcing steel and the working elements.

[0026] The device can include a control system, particularly a digital one, and / or a digital connection to user software (app). This enables, for example, automatic angle detection and / or a programmable bending / straightening / cutting sequence. Furthermore, the bending / straightening / cutting process can be documented. The device can also be equipped with a digital interface that enables, in particular, automatic control and / or documentation of the bending, straightening, and cutting processes. This can be achieved through app integration or an electronic control system with automatic angle detection and storable gripping, bending, straightening, and / or cutting sequences. Additionally, a connection to construction site management software (E 1250129) is possible. T Th Thomas Notary f francesco GSKH February 26, 2026

[0027] This is done to ensure efficient planning and documentation of work processes.

[0028] The support element, or rather the (force or torque) counter-holder, can include a support arm or be formed from one. The support element can be movable, for example, parallel to the direction of the drive shaft of the drive assembly. To make the bending / straightening / cutting device easier to stow and less bulky, the support element can, for example, be pivotable, such as by means of a support element joint.

[0029] Further simplification of bending, straightening, and cutting is achieved when the drive unit includes a motor, particularly an electric motor, which can be mounted on the device, and / or a drive lever, which can also be mounted on the device. The lever enables cost-effective and simple operation of the device. The electric drive motor serves as the drive element of the device and further reduces the effort required by the user, allowing for the effortless bending, straightening, and cutting of numerous pieces of iron in succession during work on the construction site. A pneumatic and / or hydraulic drive element, or a drive element with a hand clutch, may also be provided.

[0030] The drive unit can include a gearbox, in particular a torque multiplier, wherein the gearbox, in particular the torque multiplier, is preferably arranged between a drive shaft of the drive unit and the working element(s). Torque multipliers are readily available as inexpensive accessories in the tool industry. This eliminates the need for a long lever arm to generate the required torque, making the device compact and suitable for use even where there is little installation space or room for attaching a lever on the construction site. The support element can preferably be arranged on the gearbox housing or on the housing of the torque multiplier. E 1250129 wo T T h Thomas Notary f francesco GSKH February 26, 2026

[0031] Particularly efficient bending of rebar ends from the storage box of the reinforcement assembly is achieved when the working element comprises at least one working plate, in particular a rectangular one, and in particular a metal working plate, wherein at least one lever element, in particular a wedge-shaped cylindrical or bolt-shaped and / or partially flat, inclined, conical and / or partially pointed, is arranged on the working plate, which is suitable for gripping the reinforcing steel, in particular for gripping behind it. The working element can be formed as a flat (retaining) plate, for example as a metal plate. The (retaining) plate can be detachably connected to the drive shaft of the drive unit or to an output shaft of a torque multiplier of the drive unit by means of a plug-in or screw fastening, so that a first working element can be exchanged for a second or further working elements.It can be advantageous to use a large plate for reinforcing bars with a large diameter (approx. 25 mm) and a small plate for reinforcing bars with a small diameter (approx. 6 mm). One or more lever elements can be arranged on one or both flat sides of the (holding) plate, for example, at or next to the corners of a square or rectangular (holding) plate. If the lever elements (hooks) are arranged on both flat sides of the plate, the plate can be used on both sides. This is particularly advantageous when several reinforcing bars are to be bent back, some of which are bent in a first bending direction and some others in a second bending direction opposite to the first.

[0032] A socket can be arranged or welded to the working plate, allowing the plate to be detachably mounted on an outer square of a socket receptacle of the drive unit. Alternatively, the working plate can have a punched hole in the area of ​​its center, for example with a square or hexagonal cross-section, allowing the plate to be mounted on a square or hexagonal counterpart on or to the drive shaft of the drive unit or on or to an output shaft of a gearbox of the drive unit. E 1250129 wo T T h Thomas Notary f francesco GSKH February 26, 2026

[0033] The reproducibility of bending processes can be significantly improved if the working element includes at least one positioning aid for correctly positioning itself on the reinforcing steel. For example, two lever elements (per plate or per plate flat side) can be provided, with one lever element also serving as a positioning aid. The levers can be hook-shaped. One of the hooks, for example the front hook, can act as a lifting hook, while the other (rear) hook rests directly behind the steel to be bent at the pivot point of the reinforcing steel / return connection. This positioning of the working plate directly at the pivot point of the bend prevents the reinforcing steel from exhibiting a crooked or bowed shape (swan-neck bend) in sections after bending.The positioning function of the levers / hooks also ensures that a working plate attached at an angle to the back wall of the storage box is aligned during the bending process so that the edge of the plate lies flush or almost flush with the back wall.

[0034] According to a preferred embodiment of the bending / straightening / cutting device, the support element can be adjustable, particularly with regard to its length and / or support angle. To adjust the mechanical leverage of the counter-support, the support element can be length-adjustable, for example, in a direction perpendicular or nearly perpendicular to the direction of the drive shaft, for instance, by means of a telescopic extension or a telescopic rail arrangement. The support element can be formed in one piece or in multiple parts. The support element can include a support base which—depending on the application: bending, straightening, or cutting—has a support base geometry or shape suitable for the application. The geometry / shape of the support base can be designed such that the base can be positioned on a reinforcing bar (return connection) or on the concrete component, for example, on or next to the rear wall of the storage box.If the back wall of the storage box is profiled, for example with (longitudinal) grooves, it may be provided that the geometry or shape of the support element foot matches the geometry / shape of the grooves. E 1250129 wo. T T h Thomas Notary f francesco GSKH February 26, 2026

[0035] The working element, preferably replaceable, can comprise an eccentric and / or at least one cutting blade for the cutting or separating function of the device, or be formed as an eccentric and / or a cutting blade or a pair of cutting blades, wherein the reinforcing steel between the support element and the eccentric and / or between the support element and the cutting blade or pair of cutting blades and / or between a first and a further working element can be separated by moving or rotating the eccentric or the cutting blade or at least one working element. The support element, preferably replaceable, can have at least one cutting edge for the cutting function. During the cutting function, the eccentric or the blade is rotated, whereby the steel is squeezed between the eccentric and the support element (with cutting edge) or blade or between a pair of blades until the steel material finally tears or breaks.Depending on the design of the cutting edge, the cut point of the iron can be free of burrs or jagged edges, thus significantly reducing the risk of injury on the construction site from sharp-edged or pointed iron protruding from the concrete structure after being bent out.

[0036] According to a preferred embodiment, the device comprises a combination of two or more device modules. These modules can be configured as a clamping / gripping module (gripping attachment), a bending / re-bending module (bending attachment), a straightening module (straightening attachment), or a cutting module (cutting attachment). For bending the reinforcing steel (re-bending connection), the bending attachment is mounted on the drive unit; for straightening, the straightening attachment; and for cutting, the cutting attachment. The device is equipped with interchangeable attachments that can be adapted to the specific application, including various bending angles, cutting mechanisms, and straightening attachments. This allows for flexible adaptation to specific construction site requirements. The device can therefore be offered as a (modular) accessory system or tool kit, for example, in a case where the individual attachments can be stored.There can be multiple attachments perE 1250129 where. T T h Thomas Notary f francesco GSKH February 26, 2026

[0037] A kit may be provided. Each kit may also include several (different and interchangeable) support elements. The bending attachment may include at least one working plate with lever elements (hooks) for gripping the reinforcing steel. The straightening attachment may include at least one straightening body in which a recess or groove is arranged, allowing a section of the reinforcing steel to be gripped. The cutting attachment may include at least one eccentric, the rotation of which narrows a gap formed by the eccentric and the support element (with cutting edge), allowing a section of the reinforcing steel to be cut to be positioned in the gap. The cutting attachment may include at least one cutting blade.

[0038] In a particularly efficient design of the device, the drive unit or the drive element of the drive unit may comprise or be formed from a drill, a cordless drill, or a cordless screwdriver. A (cordless) drill or cordless screwdriver may be an integral part of the device or an accessory to it. If, for example, a drill or cordless screwdriver is already available on the construction site, the device described and claimed herein can be coupled to it. In this case, the drive unit of the device comprises a connection for the chuck of the drill or cordless screwdriver and preferably a gearbox or torque multiplier arranged at the connection.

[0039] To reduce the physical strain on the user, the device described and claimed herein may be equipped with an ergonomic handle design and / or with at least vibration damping.

[0040] Improved handling of reinforcing steel, or simplified and qualitatively improved reinforcement of concrete structures in the area of ​​construction joints between adjacent concrete sections, also taking into account safety on the construction site, is further achieved by using a (cordless) drill or a cordless screwdriver according to claim 11. Accordingly, E 1250129 where T T h Thomas Notary f francesco GSKH February 26, 2026

[0042] Improved handling of reinforcing steel, or simplified and qualitatively improved reinforcement of concrete structures in the area of ​​construction joints between adjacent concrete sections, also taking into account safety on the construction site, is further achieved with an action element according to claim 12. The action element comprises at least one, in particular rectangular, action plate, in particular a metal action plate, wherein at least one, in particular wedge-shaped or bolt-shaped and / or flat and / or partially pointed, obliquely or conically shaped, lever element is arranged on the action plate, which is suitable for gripping a reinforcing steel, in particular for gripping behind it. The action element may include at least one positioning aid for the intended positioning of the action element on a reinforcing steel of a reinforcement of a concrete structure.

[0043] According to claim 13, improved handling of reinforcing steel is also achieved with a device module for a (gripping / fixing / bending / re-bending / straightening / cutting) device as described and claimed herein. Accordingly, the device module is designed to grip or engage from behind a reinforcing steel. The device module comprises a body in which at least one receptacle for a reinforcing steel is arranged. At least one movable gripping element is arranged in the body such that the reinforcing steel can be clamped between the gripping element and the receptacle by tension or pressure on the device module or by gravity. The gripping element can, for example, be formed as a (round) rod that is movable parallel to the direction of actuation of the device module in a rod guide (with a round cross-section).Preferably, a first and a second gripping element are provided, which are mechanically connected to each other via a lifting device for raising the gripping elements after the gripping process and for releasing the reinforcing steel from the receptacle. E 1250129 wo. T T h Thomas Notary f francesco GSKH February 26, 2026

[0044] According to an alternative embodiment of the gripping device module, a first and a second gripping element are connected to each other via a gripping element joint arranged on the body, so that the gripping elements form a gripping jaw. The gripping jaw includes a gripper actuation mechanism with which the gripping jaw can be opened and / or closed. The gripper actuation mechanism can comprise a sliding slot oriented in the direction of actuation or an inclined cam guide in which an actuating bolt of the device is movable, wherein the inclined cam guide causes a direction of movement extending in the direction of actuation of the device module to be translated into a direction of movement extending transversely thereto for actuating the gripping element joint.

[0045] Improved handling of reinforcing steel is achieved according to claim 18 with a device module for a device described and claimed herein, wherein the device module is designed for (re)bending the reinforcing steel or re-bending connection. The working element is formed as an action plate with at least three bolt-shaped lever elements projecting perpendicularly from the action plate, wherein the lever elements are spaced apart from one another such that, when viewed from above the surface of the action plate, they are arranged at the three corners of a (conceptually conceived) triangle. The lever elements preferably each comprise an internal thread in which a fastening screw can be arranged for attaching the lever element to a lever receptacle of the action plate and / or for releasing it from a lever receptacle of the action plate.

[0046] Improved handling of reinforcing steel is achieved according to claim 19 with a device module for a device described and claimed herein, wherein the device module is designed for cutting a reinforcing steel or a rebar connection. The support element comprises a support groove in which a section of the reinforcing steel or rebar connection can be arranged. The working element is formed as a cutting blade rotatable about the axis of rotation of the device and on a circular or circular segment-shaped rotation path, with a first and a second cutting edge, wherein the first cutting edge is rotated about a first axis of rotation and the second cutting edge is rotated about a second axis of rotation. T T h Thomas Notary f francesco “ GSKH February 26, 2026

[0047] The first cutting edge can be actuated in the opposite direction of rotation, and the second cutting edge can be actuated, wherein the circumference of the rotation path of the acting element passes directly by the knife-side opening of the support groove. The support groove can be bounded by at least one cutting edge of the support element, preferably by two opposing cutting edges of the support element. The cutting knife can include a cutting contour to optimize the cutting motion.

[0048] Improved handling of reinforcing steel is achieved according to claim 21 with a device module for a device described and claimed herein, wherein the device module is designed for cutting reinforcing steel or a rebar connection. A first and a second cutting blade are provided, each cutting blade comprising a blade arm rotatably mounted about a blade pivot axis, a blade cutting edge arranged at one end of the blade arm, and a blade arm lever arranged at the opposite end. The device module comprises at least one actuating means for actuating at least one blade arm lever, which is rotatable about the rotation axis of the device, wherein the actuating means is designed as an eccentric, an eccentrically mounted driver, or a guide pin.The actuating means can include a spring element, wherein the movement of the cutting blade(s) takes place at least section by section against the action of the spring element.

[0049] Improved handling of reinforcing steel is achieved according to claim 23 with a device module for a device described and claimed herein, wherein the device module is designed for cutting a reinforcing steel or a rebar connection. The device module comprises a transmission, in particular a bevel gear transmission, wherein the rotary motion of the device with the transmission is translated into a rotary motion of the cutting blade(s).

[0050] Improved handling of reinforcing steel or simplified and qualitatively improved reinforcement of concrete structures in the area of ​​construction joints between adjacent concreting sections, also taking into account E 1250129 where T T h Thomas Notary ffrancesco GSKH February 26, 2026

[0051] Safety on the construction site is further achieved by means of a bending method according to claim 24. In this method, an active element of a (bending) device, particularly as described and claimed herein, is applied to the bending point of the rebar connection located in the storage box. A force or torque is transmitted to the active element via a drive unit of the bending device. The rebar connection is bent out of the storage box. The force or torque can be transferred to or into the storage box or to the concrete structure via a support element of the (bending) device. The bending process is uniform and requires minimal effort. By standardizing the bending process, the quality of the reinforcement connection is optimized.

[0052] Improved handling of reinforcing steel, or a simplified and qualitatively improved reinforcement of concrete structures in the area of ​​construction joints between adjacent concrete sections, also taking into account safety on the construction site, is further achieved by means of a straightening method according to claim 25. In this method, an active element of a (straightening) device, particularly as described and claimed herein, is applied to the reinforcing steel, especially to the rebar connection. A force or torque is transmitted to the active element via a drive unit of the (straightening) device. The reinforcing steel, especially the rebar connection, is curved or bent section by section. The force or torque can be transmitted via a support element of the (straightening) device to or into the reinforcing steel or the rebar connection, or to or into the containment box, or to the concrete structure.By using the correct straightening procedure, the reinforcement is optimized with minimal effort, as unwanted curvatures or skewings of reinforcing steel / connections can be easily eliminated even with comparatively large diameters (e.g. approx. 16 mm to approx. 25 mm).

[0053] Improved handling of reinforcing steel, or simplified and qualitatively improved reinforcement of concrete structures in the area of ​​construction joints between adjacent concrete sections, also taking into account safety on the construction site, is further achieved by means of a cutting method according to E 1250129 where T T h Thomas Notary f francesco GSKH February 26, 2026

[0054] Claim 26. In this process, an active element of a (cutting) device, particularly as described and claimed herein, is applied to the reinforcing steel, in particular to the rebar connection. A force or torque is transmitted to the active element via a drive unit of the (cutting) device. The reinforcing steel, in particular the rebar connection, is cut. The force or torque can be transmitted via a support element of the (cutting) device to or into the storage box, to the concrete structure, or to a section of the reinforcing steel, in particular to a section of the rebar connection. Pointed or sharp-edged reinforcing steel can be easily shortened according to this method with minimal effort and equipment, which improves safety on the construction site where the reinforcing steel protrudes from a finished concrete section.

[0055] In the bending, straightening, and / or cutting processes described and claimed herein, the drive unit can comprise or be formed from a drill, a cordless drill, or a cordless screwdriver. Such devices are already available on most construction sites, which significantly reduces the equipment requirements, maintenance costs, and expenses for the processes described and claimed herein.

[0056] Improved handling of reinforcing steel, or rather simplified and qualitatively improved reinforcement of concrete structures in the area of ​​construction joints between adjacent concrete sections, also taking into account safety on the construction site, is further achieved by means of a concrete structure manufacturing method according to claim 28. The concrete structure comprises a first structural element and a second structural element arranged at a construction joint, wherein at least one reinforcement element with several rebar connections is provided in the area of ​​the construction joint. The rebar connections are bent out of the first structural element before the second structural element is arranged on the first structural element. The bending of the rebar connections is carried out in a controllable, in particular reproducible, manner using a bending method described and claimed herein and / or with a device described herein and E 1250129 where T T h Thomas Notary ffrancesco GSKH February 26, 2026

[0057] The bending device is subjected to stress. In this way, the re-bending connections are bent uniformly without significant force, eliminating curvatures and irregularities during bending. This reduces the time required by tradespeople on the construction site and thus also the construction costs. Furthermore, the manufacturing process improves the structural integrity, as the re-bending connections are optimally positioned in the second part of the structure.

[0058] The aforementioned components, as well as those claimed and described in the exemplary embodiments, to be used according to the invention are not subject to any special exceptional conditions with regard to their size, shape, material selection and technical conception, so that the selection criteria known in the field of application can be applied without restriction.

[0059] Further details, features, and advantages of the subject matter of the invention will become apparent from the dependent claims, as well as from the following description and the accompanying drawing, which illustrates—by way of example—an embodiment of a gripping / fixing / bending / re-bending / straightening / cutting device.

[0081] DETAILED DESCRIPTION OF EXAMPLES OF EXECUTION

[0082] Fig. 1 shows components of a bending / straightening / cutting device 1 with a gearbox 3 arranged in a gearbox housing 2, which has a drive side 4 and an output side 5, and with a support element 6 arranged on the output side, which has a support strut 7 and a counter support 8. The gearbox 3 can be designed as a torque multiplier. To reduce the material requirement and the weight of the arrangement, a material recess 9 can be provided in the support strut 7. On the output side 5 of the gearbox 3, there is a grooved guide 10 of the bending / straightening / cutting device 1, in which a guide arm 11 of a linear guide 12 of the support element 6 can be guided parallel to the direction of the drive shaft 13. The support element 6, or rather the support arm, is therefore displaceable, thus enabling optimal positioning of the support element 6 relative to the reinforcing steel 14.The guide arm 11 is detachably fixed to the groove guide 10 by means of a locking screw 15.

[0083] On the drive side 4, a drive polygon 16, for example a square or a hexagon, is arranged, allowing the assembly 1 to be mechanically connected to an (electric) drive motor. On the output side 5, there is a conically shaped transition piece 17 with a locking pin 18 and an output polygon 19. The output polygon 19 can be square or hexagonal. An active element 20 can be arranged on the output polygon 19, with which the reinforcing steel 14 can be bent, straightened, or cut.

[0084] When the guide 11 is pulled downwards as shown in Fig. 1, it can move out of the grooves. Upon reaching the cone 17, it comes to rest at the bottom and is no longer in the groove guide 10. This allows the guide 11 to move into any position. T T h Thomas Notaryf francesco GSKH February 26, 2026

[0085] The support element 6 can be rotated to any desired position and then reinserted into the grooved guide 10, so that it is once again firmly connected to the gearbox 3. The support element 6, or torque support, can have any desired shape and be equipped with a joint.

[0086] Figures 2A, 2B, and 2C schematically show some components of a bending / straightening-cutting device 1. Figure 2A shows a schematic view of the gear arrangement: The gear 3 can comprise a planetary gear (left in Figure 2A) and / or a worm gear (right in Figure 2A). Figure 2B shows a cordless screwdriver 21, whose motor forms the drive element of the bending / straightening-cutting device 1, and Figure 2C shows the gear 3 with guide arrangement 10.

[0087] As shown in Figures 3A and 3B, an angle gear 3 with a round housing cross-section (Figure 3A) or with a square housing cross-section (Figure 3B) can optionally be provided, such that the direction of the input shaft 13 is perpendicular to or nearly aligned with the direction of the output shaft (Figure 3D). The angle gear can include a planetary and / or worm gear (Figure 3C).

[0088] Fig. 4A shows a schematic side view of the gearbox housing 2 of a bending-straightening-cutting device 1 with a groove guide 10 arranged on it. Fig. 4B shows a schematic top view of the guide arm 11 with locking screw 15. The guide arm 11 can be arranged on the groove guide 10 and is displaceable therein parallel to the direction of the drive shaft 13.

[0089] Figures 4C and 4D show variants of the support element 6. According to Fig. 4C, an additional guide is provided with which the support element 6 can be adjusted in an additional direction. According to Fig. 4D, a (two-part) joint 22 is provided with which the support element 6 can be pivoted or adjusted. In the counter-holder 8 according to Fig. 4D, openings 23, preferably with internal threads, are also provided, which are arranged in the counter-holder 8. Fig. 4E shows schematic top views of two variants of a counter-holder 8 according to Fig. 4D. In the first variant (left in Fig. 4E), a sliding ramp 24 is provided at the end, where T T h Thomas Notary f francesco GSKH February 26, 2026

[0090] In the second variant (right in Fig. 4E), a pressure or sliding roller 25 is provided at the end. The sliding ramp 24 or roller 25 serves to prevent the force from being applied to a single point on the box, but rather to enable a sliding movement. The sliding roller 25 can be particularly useful when the concrete has not yet fully hardened. This prevents the surface of the storage box from detaching due to the force exerted by the support arm 6. The effort that would be required if the defective box had to be cut out of the concrete structure is thus eliminated.

[0091] Fig. 5A schematically shows various views of different variants of the working element 20, which can be mechanically connected to the output side 5 of the gearbox 3 of the bending-straightening-cutting device 1. The working element 20 comprises a working plate or holding plate 26 and several lever elements or hooks 27, which are arranged on the flat side of the holding plate 26 and with which the reinforcing steel 14 can be gripped for bending / straightening. The hooks 27 can be shaped differently, for example tapered (top left in Fig. 5A) or with a radius (bottom left and center in Fig. 5A) or with a sloping surface (right in Fig. 5A) or with a (support) recess 28. The hooks 27 can be welded to the plate 26 or, after (laser-cutting) the contour of the plate 26, by section-by-section bending of the plate edges.

[0092] The plate 26 has a recess 29 for the output polygon 19, for example, by punching or laser cutting. The recess 29 can have a square cross-section (Fig. 5A), for example for an output square, or a rectangular cross-section (Fig. 5B). The shape of the flat retaining plate 26 can be square or rectangular (left in Fig. 5A). The retaining plate 26 can have at least one radius on at least one edge (right in Fig. 5A).

[0093] The actuating element 20 or the retaining plate 26 can alternatively or additionally be fastened to the gearbox 3 with a screw. This facilitates the replacement of the actuating element 20 or the attachment on the gearbox 3. E 1250129 wo T T h Thomas Notary f francesco GSKH February 26, 2026

[0094] Other components can be mounted on the gearbox 3, e.g. for bending or cutting operations.

[0095] Fig. 5C shows an arrangement with two retaining plates 26, which are arranged opposite each other at the ends of a rotary rod 31 by means of a sleeve connection 30. The rotary rod 31 has a rotary rod polygon 32 at its end, which can be arranged, for example with an adapter, on the output polygon 19 of the bending-straightening-cutting device 1. This is shown in Fig. 6C.

[0096] Figures 6A and 6B show a schematic side view of a section of a concrete structure 33 or structure component in which reinforcing bars 14 are arranged. For illustrative purposes, only one reinforcing bar 14 is shown in each of Figures 6A and 6B. The reinforcing bar 14 can be formed as a rebar connection, which is arranged in a storage box 34 and must be bent out of the storage box 34 before another concrete structure component (not shown in the figures) is attached to the depicted structure component 33.

[0097] Fig. 6A shows a front view of the bending and straightening device 1, in which the retaining plate 26 is arranged on the reinforcing bar 14. The reinforcing bar 14 is arranged section by section within the concrete structure part 33 and projects section by section out of the concrete structure part 33, with the protruding part resting on the surface of the concrete structure part 33. The hooks 27 of the retaining plate 26 engage behind the reinforcing bar 14. By actuating the drive element in or on the bending and straightening device 1, the retaining plate 26 is rotated (clockwise according to Fig. 6A), thereby bending the protruding part of the reinforcing bar 14 out of the concrete structure part 33.

[0098] An advantage of the retaining plate 26 with first (left) hook 27 and second (right) hook 27 is that it can be used on both sides (left and right of the iron 14). The hook 27 arranged on the left side of the plate 26 in Fig. 6A serves as a lifting hook, while the hook 27 on the right side of the plate 26E in Fig. 26E 1250129 is used for lifting. T T h Thomas Notary f francesco GSKH February 26, 2026

[0099] The hook 27 is positioned directly behind the iron 14 to be bent at the pivot point 35. Bending the iron 14 with this hook arrangement prevents unsightly swan-neck bends. When the plate 26 is positioned at an angle of approximately 45° to the iron 14, it is drawn towards the iron 14 to be bent back upon contact with the surface of the holding box 34 when the drive of the bending device 1 is activated. In this respect, the hook 27 shown on the right side of the plate 26 in Fig. 6A also serves as a positioning aid for the bending device 1. The optimized positioning of the working element 20 (plate 26) firmly supports the iron 14 and prevents undesirable deformations. In practice, i.e., on the construction site, the holding plate 26 is first slid under the iron 14. Only then is the iron 14 bent back into the desired position using the drive device.This approach is significantly more effective, faster and easier, as the user does not have to hold all the equipment while the plate 26 is threaded under the reinforcing bar 14.

[0100] According to Fig. 6B, the portion of the reinforcing bar 14 protruding from the concrete structure section 33 is located in a storage box 34 of a reinforcement arrangement. The working element 20, formed as a retaining plate 26 with tapered hooks 27 or lever elements, is arranged on the reinforcing bar 14. The support element 6 rests on the edge of the concrete structure section 33 and, when the drive of the bending-straightening device 1 is actuated, forms a counter-support 8 or a torque support.

[0101] A bending, straightening, and cutting device 1 with a cutting attachment 36 is shown in Fig. 7B. A detailed view of the cutting attachment 36 is shown in Fig. 7A. The cutting attachment 36 comprises a first cutting blade 37, and a second cutting blade 37 is arranged on the counter-holder 8 (see Fig. 7B). By rotating the cutting device 1, for example by means of a cordless screwdriver 21, which is arranged on the output side 5 of the gearbox 3, the distance between the pair of cutting blades 37 is continuously reduced until the reinforcing steel 14 is cut. T T h Thomas Notary f francesco GSKH February 26, 2026

[0102] Figure 8A / B schematically shows a bending / straightening / cutting device 1 with a variant of a bending attachment 38. The cylindrical bending die 39 has a bending guide receptacle 40 in which a reinforcing bar 14 can be arranged. The bending guide receptacle 40 is located in a bending die 39 (Figure 8B). By rotating the bending die 39, in which the bar 14 is arranged, the bar 14 is bent. The bending die 39 can be positioned at any desired point on the bar 14.

[0103] In the arrangement shown in Fig. 9, a lever tool 41 can be used to position and engage the reinforcing bar 14. This lever tool can be inserted into the (square) recess 29 of the retaining plate 26. This allows the retaining plate 26 to be positioned with minimal equipment and effort before the gear-drive unit is connected to the plate 26. To improve ergonomics, the lever tool 41 can have a bend 42 or curve at its end. A hammer 43, which should be readily available on the construction site, can also be used as the lever tool 41. The head of the hammer 43 can be inserted into the (square) recess 29 of the retaining plate 26, and the plate 26, which is attached to the hammer 43, can be positioned on the reinforcing bar 14 using the hammer 43.

[0104] As shown in Fig. 10, an operating element 20 with two mechanically coupled retaining plates 26 is provided. This allows two parallel and spaced-apart reinforcing bars 14 to be bent out simultaneously. The arrangement according to Fig. 10 can be coupled to a bending device 1 with gearbox 3 and, if necessary, with a drive unit, and only one bending operation is required to bend two bars 14 out of the storage box 34 of the reinforcement arrangement.

[0105] A gripping / bending device module (48) is shown in different (sectional) views in Figs. 11A and 11B. In the concrete part 33, a re-bending connection formed from a reinforcing bar 14 is arranged according to Fig. 11A. Two gripping elements 46 are arranged in the gripping module 48. The gripping elements 46 are formed as round rods. These are guided in rod guides 60 with a round cross-section. T T h Thomas Notary f francesco GSKH February 26, 2026

[0106] The rods 46 are movably arranged in the vertical direction within the body 61 of the gripping module. A bolt 44 is arranged at the end of each rod, allowing the rod 46 to be displaced vertically. The rods 46 are mechanically coupled to one another by a connecting web 45. The receptacle 29 is arranged on the body 61 of the gripping module 48, in which, for example, the output polygon 19 of the gripping / bending device 1 can be arranged.

[0107] A perspective view of the gripping module 48 according to Fig. 11 A is shown in Fig. 11 B. Fig. 11 C shows further views. When the gripping module 48 is placed onto the reinforcing bar 14, the gripping elements 46 are initially lifted slightly until the reinforcing bar 14 is positioned in the receiving space 49 of the body 61 of the gripping module 48. The gripping elements 46 then fall into a lower gripping position due to gravity. At their lower ends, the gripping elements 46 have a shallow, inclined surface, preferably roughened, which is suitable for engaging the gap between the reinforcing bar 14 and the lateral boundary of the receiving space 49. The ends of the gripping elements 46 each form a clamping wedge.When the gripping module 48 is moved vertically upwards, an interaction occurs between the reinforcing bar 14 and at least one of the two gripping elements 46, preferably between the reinforcing bar 14 and both gripping elements 46. This interaction causes the reinforcing bar 14 to be pressed against the inner wall of the receiving space 49. The force transmission between the gripping element 46, the receiving space 49, and the reinforcing bar 14 is then increased when the lifting or tensile force on the gripping module 48 is increased.

[0108] When the reinforcing steel shown in Fig. 11 is bent back, a torque is transmitted to the gripping module or gripping-bending module via the connection 29. One of the two gripping elements 46 then assumes the function of the working element 20 of the gripping / bending module. According to Fig. 11, the gripping element 46 shown on the right is the working element 20 for bending back the reinforcing steel 14.

[0109] To release the gripping element 48 from the reinforcing steel after gripping / bending, the connecting web 45 is moved vertically upwards, thereby releasing the E 1250129 where T T h Thomas Notary f francesco GSKH February 26, 2026

[0110] The gripping elements and the gripping / bending module 48 can be removed from the reinforcing bar 14. Bolts 44 and connecting web 45 form a lifting device 72 for the gripping module 48. Spring elements 47 can be provided to improve the positioning of the rods 46 in the body 61.

[0111] Figures 12A to 13B each schematically show different embodiments of gripping modules. According to Fig. 12A, the gripping module comprises receiving elements 54 for receiving the reinforcing steel 14. The receiving elements 54 are connected to clamping elements 51, with a sliding wedge 50 arranged between the clamping elements 51. The sliding wedge 50 is shown in perspective in Fig. 12B. The sliding wedge 50 includes a sliding slot 52 through which the transverse bolt 53 extends. A compression spring with a sleeve (58) is located on the transverse bolt 53.

[0112] One variant of the sliding wedge 50 is shown in Fig. 12C. According to this figure, the sliding wedge 50 comprises an inclined cam guide 55, which effects a change in the direction of forces / moments. A receptacle 29 for an output polygon 19 is also arranged on the sliding wedge 50.

[0113] In the gripping module variant according to Figures 13A / B, a tension wedge element 56 with a connecting element 59 is provided. The wedge 56 is arranged between the clamping elements 51 of the receiving elements 54. A tensile force acting vertically upwards on the wedge 56 causes the receiving elements 54 to grip the reinforcing steel 14, which is to be arranged in the clamping space 57, increasingly more tightly with increasing tensile force.

[0114] The modular concept of the gripping / fixing / bending / rebending / straightening / cutting device 1 is illustrated in perspective in Fig. 14. A support element 6 can be mounted on the housing 2 of the torque multiplier 3. Depending on the bending requirements, e.g., on the construction site, a gripping or gripping / bending module 48, a first bending module 62, a second bending module 63, or a third bending module 64 can be mounted on the output polygon 19 of the drive assembly. Alternatively to the gripping and bending modules 48, 62, 63, 64, a cutting module, a [E 1250129 wo] T T h Thomas Notary f francesco GSKH February 26, 2026

[0115] Straightening module, etc., can be attached. For example, on the construction site, a reinforcing bar 13 can first be bent using the bending or gripping / bending module 48, 62, 63, 64. The bending module is then removed from the drive unit and replaced with a cutting module, allowing the reinforcing bar 14 to be cut to the desired length after bending. Only one drive unit is required for bending and subsequent cutting with bending and cutting attachments. The motor of the drive unit is a cordless screwdriver, which is usually available on every construction site.

[0116] Various views of a bending module 65 are shown in Fig. 15. The bending module is mounted on the output side of the drive unit with a support element 6. The bending module comprises an actuating plate 26 with three lever elements 27, each formed as a bolt. The bolts 27 may have an internal thread so that they can be fastened to the actuating plate 26 with a screw. The bolts 27 are arranged so that they are located at the corners of a (conceptual) triangle. The reinforcing bar 14 is positioned between the bolts 27. The plate 26 is rotated by the drive unit about the drive axis of rotation of the device 1. The torque is thereby transmitted to the bolts 27 and from there to the reinforcing bar. By supporting the reinforcing bar with the rigid support element, the reinforcing bar is bent in the area of ​​the plate 26. Bending angles in a range between approximately 10° and approximately 170° are possible.Depending on the direction of rotation of the device 1, the first and second bolts 27 form an active element 20 of the bending module, or the first and third bolts form one. The arrangement of the plate 26 with the bolts 27 according to Fig. 15 allows the user to bend the reinforcing steel 14 even in situations where there is not much space around the reinforcing steel.

[0117] A cutting module 66 for cutting reinforcing steel 14 is shown in various views in Fig. 16. The support element 6 has the shape of a circular segment and includes a support groove 67. By partially enclosing the output axis and thus being connected to the cylindrical housing of the torque multiplier, the force applied for cutting is transferred via E 1250129 where T T h Thomas Notary f francesco GSKH February 26, 2026

[0118] The housing of the device is derived from this. The working element 20 comprises two cutting blades 37. The cutting blades 37 are arranged on a round working plate 26, which is rotated by the device 1. During this rotation, the cutting blades 37 move towards the support element 6, so that the reinforcing steel 14 is cut by the cutting blades 37. The boundary of the support groove 67 also includes cutting edges 68, which optimizes the cutting action.

[0119] Figures 17A to 17G show various versions of cutting modules 66, some in different views. According to Fig. 17A, the cutting module 66 comprises a movable working element 20 with a cutting blade 37 and a support element, which also includes a cutting blade 37. The working element 20 is laterally movable by means of an eccentrically rotatable actuating bolt 69. The working element 20 and the support element 69 form a pair of cutting blades.

[0120] As shown in Figures 17B and 17C, the cutting module 66 has two working elements 20, each of which is laterally movable. During cutting, the working elements 20 move towards each other, like scissors. The cutting module 66 can be mounted on the output side of the device 1 using the multi-sided mounting 29.

[0121] The exploded views according to Figures 17D to 17 reveal variants of cutting modules 66 in which the working elements 20 are actuated by an eccentric 70. The oval shape of the eccentric 70 causes the pairs of cutting blades to move around the axis of rotation of the blade pair.

[0122] In the cutting module variant according to Fig. 18, the torque is transmitted from the drive arrangement to the two working elements 20 with cutting blades 37 by means of a bevel gear 71. Thomas Notarfrancesco ■ “ GSKH
