Description

The invention relates to a setting tool according to the preamble of claim 1 and a method for strikingly driving an anchor rod into a borehole according to the preamble of claim 12. A setting tool according to the preamble of claim 1 is from the DE 10214676A1 known.

In the EP 3546127 A1 A setting tool and a method for driving an anchor rod into a borehole are described. The setting tool is particularly suitable for being used by a robot, so that the method using the setting tool is carried out in particular by a robot.

The setting tool according to EP 3546127 A1 has a drive-side end and an end facing away from the drive in a tool direction. It has a tool adapter forming the drive end, which is designed and arranged in such a way that it can interact with a driven driving tool. The end facing away from the drive is formed by a receiving element which has a recess which is designed and arranged in such a way that it can accommodate a part of an anchor rod extending in the tool direction away from the end facing away from the drive. The tool adapter and the receiving element are coupled to one another in such a way that an impact force oriented in the tool direction and directed towards the end facing away from the drive and introduced via the tool adapter is transmitted to an anchor rod arranged in the recess of the receiving element. After driving the anchor rod into the drill hole, the setting tool must be removed from the anchor rod that is firmly anchored in the drill hole. Problems can arise with the known setting tool, in particular the anchor rod becoming jammed in the recess of the receiving element.

The EP 3103591 A1 and WO 2014/076125 A1 also describe setting tools for driving an anchor rod into a drill hole.

In contrast, it is in particular the object of the invention to propose a setting tool and a method for driving an anchor rod into a borehole, which enable reliable driving of anchor rods, in particular by an automated assembly device. According to the invention, this object is achieved with a setting tool with the features of claim 1 and a method for strikingly driving an anchor rod into a borehole with the features of claim 12.

The setting tool according to the invention for driving an anchor rod into a borehole in a substrate has a drive-side end and an end facing away from the drive in a tool direction. It has a tool adapter, in particular forming the drive end, which is designed and arranged in such a way that it can interact with a driven driving tool. The end facing away from the drive is formed in particular by a receiving element which has a recess which is designed and arranged in such a way that it can receive a part of an anchor rod which extends in a guide direction away from the end facing away from the drive. The tool adapter and the receiving element are coupled to one another in such a way that an impact force oriented in the tool direction and directed towards the end facing away from the drive and introduced via the tool adapter is transmitted to an anchor rod arranged in the recess of the receiving element. The tool adapter and the receiving element are coupled by means of a coupling element, which is designed and arranged in such a way that it enables displacement of at least part of the receiving element transversely to the tool direction relative to the tool adapter. The said displacement of the receiving element can be carried out, for example, by pivoting the receiving element relative to the tool adapter transversely to the tool direction and/or displacing the receiving element transversely to the tool direction. The displacement can also have a component in the tool direction. The coupling element thus represents a connection between the tool adapter and the receiving element that is flexible in a direction transverse to the tool direction. The coupling element is designed in such a way that it enables the aforementioned displacement transversely to the tool direction during the striking driving of the anchor rod into a borehole in a substrate. The coupling element thus enables the aforementioned displacement transversely to the

Tool direction the mentioned driving before removing the setting tool from the driven anchor rod.

According to the invention, the coupling element is designed as a coil spring. In particular, it is arranged so that its axial direction runs in the direction of the tool. Coil springs are available on the market in a variety of designs at low cost. The design of the coupling element as a helical spring thus enables a particularly cost-effective setting tool. In addition, a coil spring has the necessary flexibility transversely to its axial direction.

The coil spring consists in particular of metal, for example so-called spring steel. This makes it particularly robust.

When an anchor rod is inserted into the receiving element, it is aligned in the guide direction by the guided receptacle in the receiving element. If no forces act transversely to the tool direction on the anchor rod or the receiving element, the guide direction is the same as the tool direction. As long as the anchor rod is aligned in the guide direction or only has a slight deviation from the guide direction, the setting tool can be removed from the anchor rod without any problems.

When an anchor rod is driven into a borehole, it inevitably aligns with the path of the borehole; It assumes an anchor rod direction that is determined by the course of the borehole. When drilling a borehole into a substrate, especially in concrete, it can happen that the actual course of the borehole deviates from a desired or intended target course. For example, there may be an angular offset of a few degrees, for example up to 10°, and/or a transverse offset in the range of a few millimeters, for example up to 5 mm, compared to the target course. It can therefore happen that an anchor rod partially accommodated in the recess of a receiving element has an anchor rod direction that deviates from the guide direction. To ensure that the setting tool can be easily removed from the anchor rod in this case, the guide direction should be adapted to the anchor rod direction, at least when it is removed.

The tool direction is determined by the orientation of the driving tool. In particular, when guiding the driving tool with an automated assembly device, the orientation of the driving tool is predetermined by the automated assembly device. The specification is based in particular on the desired course of the borehole known to the assembly device. If the receiving element has no possibility of displacement transversely to the tool direction and therefore no possibility of changing the orientation of the guide direction relative to the tool direction, the guide direction cannot adapt to the anchor rod direction specified by the course of the actual drill hole. This means that if the guide direction deviates from the anchor rod direction, the anchor rod can become jammed in the recess of the receiving element. Such jamming in particular means that the setting device can no longer be easily removed from the anchor rod after the anchor rod has been driven into a borehole. Driving the anchor rod into a borehole cannot be completed reliably. The problem described occurs in particular when using an automated assembly device.

The coupling element of the setting tool according to the invention enables at least part of the receiving element to be displaced transversely to the tool direction and thus a change in the orientation of the guide direction relative to the tool direction. Thus, with a fixed tool direction, the guide direction can adapt to the anchor rod direction if this is determined by the course of a borehole as described. The coupling element is designed in such a way that it can compensate for the above-mentioned angular offset and transverse offset. As described, the course of the guide direction corresponding to the anchor rod direction ensures that the setting tool can be easily removed from driven anchor rods and thus a reliable driving of anchor rods into a borehole, in particular by means of an automated assembly device. It is particularly advantageous to reliably drive several anchor rods into drill holes one after the other without the need for manual intervention by an operator of the automated assembly device. This enables a particularly cost-effective use of the setting tool. The mounting device can, for example, be like one in the WO 2017/016783 A1 The assembly device described can be carried out.

The anchor rod has a mainly cylindrical basic shape. It is in particular made of metal and can in particular be part of an expansion anchor, preferably a bolt-type expansion anchor. An expansion anchor is characterized in particular by the fact that it has a displaceable expansion element, for example an expansion sleeve, which is pushed radially outwards by an expansion body arranged on the anchor rod when the expansion body is axially offset relative to the expansion element. In order to enable the above-mentioned displacement of the expansion body to the expansion element, the anchor rod in particular has an external thread onto which a nut can be screwed after being driven into the borehole and clamped against the substrate containing the borehole, for example in the form of a wall. As a result of the bracing mentioned, the anchor rod is pulled out of the borehole again and the expansion body is thus displaced axially relative to the expansion element. The nut mentioned and any washer that may be present can already be screwed onto the external thread while the anchor rod is being driven in or can only be screwed on after driving in.

In the simplest case, the tool adapter is cylindrical at the drive end. But in particular it has an outer contour that is adapted to the drill chuck of the driving tool. For this purpose, the drive-side end can, for example, be designed mainly cylindrical and have two opposite grooves running in the tool direction.

The driving tool can in particular be electrically driven, but a pneumatic or hydraulic drive is also conceivable. In particular, the driving tool only carries out a striking movement, but not a rotational movement at the same time. It is designed as a percussion hammer that is operated in a so-called chisel mode.

The recess of the receiving element is in particular cylindrical. The diameter of the recess is then adapted to a diameter of the anchor rod so that the anchor rod is aligned through the recess in the guide direction and guided into a borehole when driven. The receiving element can be designed so that it has an anchor rod without a screwed-on nut or with can accommodate a screwed-on nut. The recess is in particular adapted to the part of the anchor rod to be received in such a way that the said part of the anchor rod is received by the recess without or only with little play transversely to the tool direction.

The tool adapter, the coupling element and the receiving element are made in particular from metal, for example from so-called tool steel.

In an embodiment of the invention, the tool adapter, the receiving element and the coupling element are designed and arranged in such a way that the aforementioned impact force or at least a part of it is transmitted directly from the tool adapter to the receiving element. The coupling element is designed in particular in such a way that it is not involved in the transmission of the impact force, or at least only to a negligible extent. This means that the coupling element does not have to be dimensioned and designed in such a way that it can transmit forces in the tool direction to a significant extent. It can therefore be carried out simply, easily and inexpensively.

The tool adapter, the receiving element and the coupling element are in particular designed and arranged in such a way that the receiving element has a contact surface with the tool adapter, at least when transmitting the impact force, via which the impact force can be transmitted. The receiving element then transfers the impact force to the anchor rod.

In an embodiment of the invention, the tool adapter, the receiving element and the coupling element are designed and arranged in such a way that the aforementioned impact force or at least a part of it is transmitted directly from the tool adapter to an anchor rod arranged in the recess of the receiving element. The coupling element and the guide element are designed in particular in such a way that they are not involved in the transmission of the impact force, or at least only to a negligible extent. This means that the coupling element and the receiving element do not have to be dimensioned and designed in such a way that they can transmit forces in the tool direction to a significant extent. They can therefore be carried out simply, easily and inexpensively.

The tool adapter, the receiving element and the coupling element are in particular designed and arranged in such a way that an anchor rod arranged in the recess of the receiving element has a contact surface with the tool adapter, at least during the transmission of the impact force, via which the impact force can be transmitted. For this purpose, the receiving element is designed in particular as a sleeve that is open both in the direction of the end facing away from the drive and in the direction of the tool adapter.

In an embodiment of the invention, the tool adapter and/or the receiving element have a thread onto which the coupling element designed as a coil spring is screwed. This enables a particularly simple and cost-effective coupling of the tool adapter to the receiving element. It is particularly advantageous if both the tool adapter and the receiving element have a thread. The threads on the tool adapter and on the receiving element are particularly identical. This means that a coil spring with a constant diameter can be used. In addition, in this case, the orientation of the coil spring does not have to be taken into account when assembling the setting tool. The threads are in particular designed as external threads.

The coupling element can be made of an elastomeric material, i.e. an elastomer, in an embodiment of a setting tool that is not included in the scope of protection of the claims. An elastomer is a dimensionally stable but elastically deformable plastic. The aforementioned deformability of the coupling element enables the necessary displacement of at least part of the receiving element relative to the tool adapter transversely to the tool direction. Components made of elastomers with different properties can be produced easily and cost-effectively, which enables a particularly cost-effective setting tool. In addition, elastomers are very resistant, so that the setting tool can be used for a long time.

In this embodiment of a setting tool, which is not included in the scope of protection of the claims, the connection between the tool adapter and the receiving element can be made by means of the coupling element, for example, in a frictional or positive manner. It is also conceivable that the coupling element is connected to both the tool adapter and also to the receiving element, for example is glued.

In particular, in this embodiment of a setting tool, which is not included in the scope of protection of the claims, the tool adapter and the receiving element overlap in an overlap area in the tool direction. For example, the receiving element in the overlap area is arranged radially further out than the tool adapter, although a reverse arrangement is also possible. The coupling element is then arranged in the overlap area. The coupling element is clamped in particular between the tool adapter and the receiving element and thus establishes a frictional connection between the tool adapter and the receiving element. Alternatively or additionally, the coupling element can be glued to the tool adapter and/or the receiving element. Alternatively or additionally, a positive connection of the coupling element to the tool adapter and/or the receiving element is also possible.

In particular, the tool adapter of this configuration of a setting tool, which is not included in the scope of protection of the claims, has a mainly cylindrical basic shape in the overlap area and the receiving element has a mainly hollow cylindrical basic shape, an inner diameter of the receiving element being a little larger, for example between 4 and 20 mm, than an outer diameter of the tool adapter. The also hollow cylindrical coupling element made of elastomer is then arranged between the tool adapter and the receiving element.

In an embodiment of the invention, the receiving element has a holding element which is designed and arranged in such a way that it can apply a holding force oriented in the guide direction and directed towards the drive end to an anchor rod arranged in the recess of the receiving element, which results in the anchor rod being removed in the guide direction from the recess of the receiving element counteracts.

This means that an anchor rod, including any associated components, can be picked up with the setting tool and inserted into the drill hole. This means that no second hand or additional gripping device is necessary for inserting and then setting or driving in the anchor rod. When a worker sets the anchor rod, he only needs one hand to guide the powered driving tool; with For example, he can secure himself with the other hand. This is particularly important when the worker is on a work platform, for example in an elevator shaft of an elevator system. The setting tool enables the anchor rod to be driven in easily, quickly and safely for the worker. The setting tool according to this embodiment particularly advantageously enables an anchor rod, including any associated components, to be picked up and driven into a borehole by an automated assembly device using only the setting tool, i.e. without a time-consuming tool change. No additional tools are required to pick up the anchor rod and insert it into the drill hole. The assembly device therefore only requires a manipulator that guides the setting tool, for example in the form of a robot, and no second manipulator that guides a gripping tool. The setting tool thus particularly advantageously enables the anchor rod to be driven in quickly using an automated assembly device, which also only needs to have one manipulator and can therefore be designed to be comparatively simple and inexpensive.

The holding element can permanently apply the holding force mentioned to an anchor rod arranged in the recess of the receiving element. However, it is also possible for the holding element to only apply the holding force when a pull-out force oriented away from the end facing away from the drive acts in the guide direction. Without the opposing holding force, the pull-out force mentioned would lead to the anchor rod being removed from the recess in the receiving element. The holding force is then a reaction force to the pull-out force mentioned. It can, for example, be based on friction, in particular static friction, between the holding element and the anchor rod or on a positive connection between the holding element and the anchor rod, for example with a thread of the anchor rod.

The holding force can also have a component transverse to the guide direction. The holding force is in particular greater than a weight force of the anchor rod and any components associated with the anchor rod, such as a nut, washer and/or expansion sleeve. The holding force can exceed the weight force mentioned, in particular by a safety margin. It is therefore chosen in particular so that an anchor rod standing in a magazine, including associated components, can be removed upwards from the magazine using the setting tool, without the anchor rod falling out of the setting tool and without the need for another tool, for example in the form of a gripping tool. The holding force is, for example, greater than 0.5 N - 2.5 N.

In an embodiment of the invention, the receiving element has at least one magnet as a holding element, which can apply the holding force mentioned to a magnetizable anchor rod. This means that a permanent or permanent holding force can easily be applied to the anchor rod. In addition, the holding force acts without mechanical interaction between the receiving element and the anchor rod, so that no wear or tear occurs on the receiving element.

A magnetizable anchor rod or, more generally, a magnetizable component is to be understood here as a component that is attracted by a magnet, i.e. can be magnetized by a magnet at least temporarily. Anchor rods are made, for example, of steel with a so-called ferritic structure, for example of electroplated nickel-plated steel, and can therefore be magnetized.

The magnet mentioned is designed in particular as a permanent magnet and specifically as a permanent magnet made of a neodymium-iron-boron alloy with the composition Nd ₂ Fe ₁₄ B. The receiving element can have one or more magnets which are arranged one behind the other in the guide direction.

The magnet is arranged in particular around the recess of the receiving element. This enables a simple structure of the receiving element. The magnet can, for example, be designed in a ring shape. Since there are a large number of ring-shaped magnets available on the market, it is easy to find a suitable and cost-effective magnet.

The magnet or magnets can be arranged partially or completely offset in the guide direction relative to the recess.

The magnet is arranged in particular in the guide direction between the recess of the receiving element and the drive-side end. The magnetic one The attractive force between the magnet or magnets and the anchor rod acts directly in the guiding direction and thus causes a very strong holding force on the anchor rod.

It is also possible for the receiving element to have both a magnet that is arranged around the recess of the receiving element and a magnet that is arranged in the guide direction between the recess of the receiving element and the drive-side end. This allows a particularly strong holding force to be generated.

It is also possible for at least part of the receiving element and/or the tool adapter to be magnetic, i.e. designed as a magnet. The receiving element is non-magnetic, particularly in the area of the recess, in order not to hinder the insertion of an anchor rod.

In particular, a bottom of the recess of the receiving element is formed by a striking plate and the magnet connects to the striking plate in the direction of the drive-side end. This means that the magnet can be protected from damage when the anchor bolt is driven in by the striking plate, which enables the setting tool to have a long service life.

The bottom of the recess of the receiving element is to be understood here as a termination of the recess in the direction of the drive-side end. The striking plate consists in particular of a durable material, in particular of hardened steel, in particular of tool steel. It is therefore not damaged when an anchor bolt is hammered in and can, in particular, effectively protect the magnet from damage. The striking plate can, for example, be secured in the guide direction by a locking ring, in particular a metal ring, arranged in a circumferential groove of the recess. It is also possible for the striking plate to be clamped between two components of the receiving element and thus also secured in the guiding direction.

In an embodiment of the invention, the receiving element has a pressing element, which is designed and arranged in such a way that it pushes the magnet in the direction of the striking plate presses. This means that the magnet can advantageously avoid strong impacts and thereby be protected from damage. However, the pressure element still presses it back into its target position, i.e. adjacent to the striking plate.

The pressing element is arranged, for example, as a spring, in particular a spiral spring arranged in the guide direction and at least slightly prestressed, which is arranged between the magnet and the drive-side end. It is also possible that the pressing element consists of an elastic material, for example foam, and is also arranged between the magnet and the drive end.

In particular, the receiving element, with the exception of the striking plate, magnet and pressing element, consists exclusively of non-magnetizable material. This means that the other, non-magnetizable components of the receiving element cannot disturb the magnetic field of the magnet or magnets, so that the magnet exerts a particularly strong holding force on the anchor rod. It is also possible that the pressing element also consists of non-magnetizable material.

The other, non-magnetizable components of the receiving element consist in particular of chrome-nickel steel with an austenitic structure.

In an embodiment of the invention, the holding element is designed as at least one clamping element which is elastic at least transversely to the guide direction and which reduces a cross section of the recess of the receiving element transversely to the guide direction. This means that the holding force can be applied particularly easily.

The combination of recess and clamping element is matched to the anchor rod to be driven in such that the clamping element reduces the cross section of the recess so much that it comes into contact with an anchor rod arranged in the recess of the receiving element. In this case, the clamping element only applies the holding force when a pull-out force oriented away from the end facing away from the drive acts in the guide direction. The holding force is then a reaction force to the pull-out force mentioned. For example, it can be due to friction, in particular static friction between the holding element and the anchor rod or on a Positive connection between the holding element and the anchor rod, for example with a thread of the anchor rod, is based.

The clamping element can be designed in different ways. It can, for example, be designed as a ring, in particular an O-ring or a metal ring, arranged in a circumferential groove in the recess of the receiving element. In the case of the design as a metal ring, the clamping element can have an inner contour, as a result of which the force for inserting an anchor bolt into the recess of the receiving element is smaller than a force for pulling the anchor bolt out of the recess. This can be achieved, for example, in that an inner diameter of the metal ring decreases slightly both from the drive-side end and from the end facing away from the drive, and the decrease in the inside diameter at the drive-side end is steeper than at the end facing away from the drive.

The clamping element is in particular designed as a mainly U-shaped clamp, the arms of which are inserted into two opposite recesses in the receiving element that are aligned transversely to the guide direction. The recesses are open inwards, so that the clip rests against a part of an anchor rod received in the recess of the receiving element. This enables a particularly simple and cost-effective holding element. The clamp mentioned is made in particular of metal.

In an embodiment of the invention, the holding element is formed by at least two, in particular three, arms which are elastic transversely to the guide direction and which are designed and arranged in such a way that an anchor rod arranged in the recess of the receiving element presses the arms outwards against a tensioning force. This enables a particularly simple design of the setting tool.

The arms thus form the end of the setting tool facing away from the drive. They are made in particular of spring steel and are attached to the receiving element, in particular screwed or riveted to the receiving element. The holding force also arises as a reaction force to the above-mentioned pull-out force on the anchor bolt.

In an embodiment of the invention, the holding element is made of an elastic Pressing element is formed with a particularly continuous recess in the guide direction. An inner diameter of the pressing element is selected such that the pressing element exerts a pressing force transversely to the guide direction on a part of an anchor rod arranged in the recess of the receiving element. This enables a particularly simple design of the setting tool.

The pressing element can, for example, consist of acrylonitrile-butadiene rubber, or nitrile rubber for short. It can have a circumferential, inwardly oriented collar, which dips into a circumferential groove of the receiving element and is thus fixed relative to the receiving element. It is also possible for the pressing element to form the only recess in the receiving element.

A slotted sleeve, in particular a slotted steel sleeve, can be arranged in the recess of the pressing element to avoid abrasion on the pressing element by the anchor rod.

The above-mentioned task is also achieved by a method for driving an anchor rod into a borehole using a driven impact tool and a setting tool with the features mentioned. The method is carried out in particular during installation of an elevator system in an elevator shaft. But it can also be used for completely different assembly work where anchor bolts have to be driven into a drill hole. The anchor rod is in particular part of an expansion anchor.

The method according to the invention has the advantages explained above in connection with the setting tool according to the invention.

• Aufnehmen einer Ankerstange aus einem Magazin mit dem Setzwerkzeug,
• Positionieren der Ankerstange fluchtend zum Bohrloch,
• Setzen der Ankerstange in das Bohrloch durch Übertragen einer Einschlagkraft des Einschlagwerkzeugs über das Setzwerkzeug auf die Ankerstange und
• Abziehen des Setzwerkzeugs von der in das Bohrloch eingetriebenen Ankerstange.

The method can in particular have the following steps:

• Picking up an anchor rod from a magazine with the setting tool,
• Positioning the anchor rod flush with the drill hole,
• Setting the anchor rod into the drill hole by transferring an impact force of the impact tool via the setting tool to the anchor rod and
• Removing the setting tool from the anchor rod driven into the drill hole.

The method is particularly characterized by the fact that the setting tool is guided by a robot when carrying out the method. The robot can in particular be part of one in the WO 2017/016783 A1 be the assembly device described.

Setting an anchor rod or an expansion anchor having an anchor rod into a borehole can therefore be carried out particularly quickly, since the robot only requires a single tool for picking up, positioning and setting the anchor rod or the expansion anchor and so no tool change is necessary between individual process steps .

It should be noted that some of the possible features and advantages of the invention are described herein with reference to different embodiments of the setting tool according to the invention on the one hand and the method according to the invention on the other hand. One skilled in the art will recognize that the features may be suitably combined, adapted, transferred or exchanged to achieve further embodiments of the invention.

Further advantages, features and details of the invention emerge from the following description of exemplary embodiments and from the drawings, in which identical or functionally identical elements are provided with identical reference numbers. The drawings are only schematic and not to scale.

According to Fig. 1 a setting tool 10 has a tool adapter 12 and a receiving element 14, which are designed as separate components. The tool adapter 12 is aligned in a tool direction 16 and has a drive-side end 18, which also forms the drive-side end of the setting tool 10. The tool adapter 12 has two sections. A first section 11 has a mainly cylindrical shape with two diametrically opposed grooves 22 running in the tool direction 16. The tool adapter 12 is intended to accept only one chuck 74 Fig. 10 shown, driven impact tool 76 to be recorded. The shape of the tool adapter 12 is adapted to the chuck 74 of the driving tool 76. The tool adapter 12 is therefore designed and arranged in such a way that it can interact with the driven driving tool 76. The first section 11 of the tool adapter 12 merges into a second section 13, which is also mainly cylindrical, but with a larger diameter than the first section 11. A striking surface 15 closes the second section 13 and thus the tool adapter 12 on a side opposite the drive-side end 18. The striking surface 15 has a collar 17 running around the outside. There is a first external thread 19 on the second section 13 arranged, onto which a coupling element in the form of a coil spring 21 is screwed.

The coil spring 21 couples the tool adapter 12 to the receiving element 14, which forms an end 20 of the setting tool 10 that is opposite to the drive in the tool direction 16. The receiving element 14 is designed as a mainly hollow cylindrical sleeve, which is aligned in a guide direction 9. The receiving element 14 is therefore designed as a sleeve that is open in two directions. The receiving element 14 has a second external thread 23 corresponding to the first external thread 19, onto which the coil spring 21 is also screwed. An outer contour of the receiving element 14 tapers in the direction of the tool adapter 12 and has a chamfer 25 corresponding to the collar 17 of the striking surface 15 of the tool adapter 12 at its end in the direction of the tool adapter 12.

The tool adapter 12 and the receiving element 14 are made, for example, from tool steel. The setting tool 10, for example, has a length between 100 and 180 mm.

The receiving element 14 has a recess 24 which is open in the direction of the end facing away from the drive and into which an anchor rod 26 of an expansion anchor 28 aligned in the guide direction 9 is inserted. The recess 24 extends in the guide direction 9 through the entire receiving element 14, so that the anchor rod 26 rests on the striking surface 15 and thus has a contact surface with the tool adapter 12.

The recess 24 has, for example, a length in the guide direction 9 between 15 mm and 30 mm and an inner diameter between 8 mm and 24 mm. The recess 24 of the receiving element 14 therefore receives a part of the anchor rod 26 which extends in the guide direction 9 away from the end 20 facing away from the drive. The anchor rod 26 is made, for example, from electroplated nickel-plated steel.

The receiving element 14 has a holding element in the form of a mainly U-shaped bracket 30, from which in Fig. 1 only her two arms 31 can be seen. To accommodate the clip 30, the receiving element 14 has two opposite recesses 52 on its outside, which run transversely to the guide direction 9. The punctures 52 are so deep that they reach into the recess 24 of the receiving element 14. The clamp 30 is arranged on the receiving element 14 in such a way that its two arms 31 run in the recesses 52 and thus reduce the cross section of the recess 24 transversely to the guide direction 9. The dimensions of the recess 24, the clamp 30 and the anchor rod 26 are selected so that an anchor rod 26 inserted into the recess 24 presses the clamp 30 outwards at least temporarily during insertion. The dimensions mentioned can be chosen so that an anchor rod 26 inserted into the recess 24 permanently pushes the clamp 30 outwards and so the clamp 30 exerts a clamping force on the anchor rod 26. It is also possible that the clip 30 is not permanently pressed outwards by an inserted anchor rod 26, but rather that the clip gets at least slightly caught on the anchor rod 26 when the anchor rod 26 is pulled out and is thus oriented in the guide direction and directed towards the drive-side end 18 Holding force exerts on the anchor rod 26 arranged in the recess 24 of the receiving element 14, which counteracts the removal of the anchor rod 26 in the guide direction 9 from the recess 24 of the receiving element 14.

The individual parts are dimensioned and coordinated with one another in such a way that the holding force mentioned on the anchor rod 26 is at least a safety margin of, for example, 20% greater than the weight of the expansion anchor 28.

The anchor rod 26 inserted into the recess 24 of the receiving element 14 and thus the expansion anchor 28 are thus secured against unintentional removal from the recess 24. The setting tool 10 and thus the inserted expansion anchor 28 could also be aligned vertically downwards without the anchor rod 26 and thus the expansion anchor 28 falling out of the recess 24. This means that an expansion anchor 28 can be removed from a magazine 70 (see Fig. 10 ) can be removed by storing it upright.

When the tool adapter 12 is inserted into the chuck of a driven impact tool and an anchor rod 26 is inserted into the recess 24 of the receiving element 14 is inserted, an impact force oriented in the tool direction 16 and directed in the direction of the end 20 facing away from the drive and introduced via the tool adapter 12 can be transmitted to the anchor rod 26 arranged in the recess 24 of the receiving element 14 and thus striking in a just in Fig. 10 Hole 60 shown is driven into a substrate, for example a shaft wall 62 of an elevator shaft 64 of an elevator system. The impact force is transmitted directly from the tool adapter 12 via the striking surface 15 to the anchor rod 26.

In Fig. 1 no force acts transversely to the guide direction 9 on the anchor rod 26 and thus on the receiving element 14. The coil spring 21 thus aligns the receiving element 14 relative to the tool adapter 12 so that the guide direction 9 and tool direction 16 run the same way. This means that an anchor rod 26 can be inserted into the recess 24 of the receiving element 14 without any problems and can also be removed again, i.e. the setting tool 10 can be removed from an anchor rod 26 driven into a borehole.

Fig. 2 shows the setting tool 10 in a state in which, due to the course of a borehole into which the anchor rod 26 is driven, the guide direction 9 has an angular offset with respect to the tool direction 16, i.e. the two directions run at an angle other than zero to one another. In this case, the coil spring 21 is deflected transversely to the tool direction 16, so that the receiving element 14 is pivoted relative to the tool adapter 12. This means that compared to the representation in Fig. 1 at least parts of the receiving element 14 are displaced transversely to the tool direction 16.

Also in the Fig. 2 In the state shown, the anchor rod 26 is correctly aligned with respect to the receiving element 14, so that the setting tool 10 can be removed from the anchor rod 26 without any problems.

In Fig. 2 an angular offset between the guide direction 9 and the tool direction 16 is shown and its compensation by means of the coil spring 21 is described. An additional or exclusive transverse offset between the guide direction 9 and the tool direction 16 can also be compensated for in an analogous manner become.

A setting tool 110 according to Fig. 3 is similar to the setting tool 10 according to Fig. 1 and 2 which is why the differences between the two setting tools are mainly discussed. The setting tool 110 also has a tool adapter 112 and a receiving element 114, which are made of a magnetizable material, for example tool steel. The tool adapter 112 is mainly cylindrical in shape and is closed off by a striking surface 115 on a side opposite a drive-side end 118. The tool adapter 112 has a first external thread 119 onto which a coupling element in the form of a helical spring 121 is screwed.

The coil spring 121 couples the tool adapter 112 with the receiving element 114, which forms an end 120 of the setting tool 110 that is opposite in the tool direction 16 and is remote from the drive. The receiving element 114 also has a mainly cylindrical basic shape. It has a second external thread 123 corresponding to the first external thread 119, onto which the coil spring 121 is also screwed. An outer contour of the receiving element 114 tapers towards the tool adapter 112.

This allows the coil spring 121 to be analogous to the coil spring 21 Fig. 1 and 2 a flexible coupling between the receiving element 114 and the tool adapter 112.

The receiving element 114 connects to the tool adapter 112 in the direction of the end 120 facing away from the drive and forms the end 120 facing away from the drive. The receiving element 114 has a recess 124 which is open in the direction of the drive away from the drive and into which an anchor rod 26 of an expansion anchor 28 aligned in the guide direction 9 is inserted. The recess 124 has, for example, a length in the guide direction 9 between 15 mm and 30 mm and an inner diameter between 8 mm and 24 mm. The recess 124 of the receiving element 114 therefore receives a part of the anchor rod 26 which extends in the guide direction 9 away from the end 120 facing away from the drive. The anchor rod 26 is made of a magnetizable material, for example galvanic nickel-plated steel.

The receiving element 114 has a holding element 130 in the form of three ring-shaped magnets 130a, 130b, 130c, which are arranged one behind the other in the guide direction 9 around the recess 124 of the receiving element 114. The receiving element 114 has, at least in the area of the recess 124, a cylindrical outer contour onto which the annular magnets 130a, 130b, 130c are pressed. The magnets 130a, 130b, 130c are arranged offset from the recess 124 in the guide direction 9 in the direction of the drive-side end 118.

The magnets 130a, 130b, 130c attract the anchor rod 126 and hold it in the position shown, i.e. inserted into the recess 124 of the receiving element 114. The holding element 130 in the form of the magnets 130a, 130b, 130c thus brings a position oriented in the guide direction 9 and holding force directed in the direction of the drive-side end 118 on the anchor rod 26 arranged in the recess 124 of the receiving element 114, which counteracts a removal of the anchor rod 26 in the guide direction 9 from the recess 124 of the receiving element 114. The magnets 130a, 130b, 130c are dimensioned such that the holding force mentioned on the anchor rod 26 is at least a safety margin of, for example, 20% greater than the weight of the expansion anchor 128.

The anchor rod 26 inserted into the recess 124 of the receiving element 114 and thus the expansion anchor 28 are thus secured against unintentional removal from the recess 124. The setting tool 110 and thus the inserted expansion anchor 128 could also be aligned vertically downwards without the anchor rod 26 and thus the expansion anchor 28 falling out of the recess 24. This means that an expansion anchor 28 can be removed from a magazine 70 (see Fig. 10 ) can be removed by storing it upright.

If the tool adapter 112 is inserted into the chuck of a driven impact tool and an anchor rod 26 is inserted into the recess 124 of the receiving element 114, an impact force oriented in the tool direction 16 and directed towards the end 120 facing away from the drive and introduced via the tool adapter 112 can be transmitted via the striking surface 115 onto the receiving element 114 and from Receiving element 114 is transferred to the anchor rod 26 arranged in the recess 124 and thus striking into a just in Fig. 10 Hole 60 shown is driven into a substrate, for example a shaft wall 62 of an elevator shaft 64 of an elevator system. The impact force is transmitted directly from the tool adapter 112 via the striking surface 115 to the receiving element 114.

When describing the further exemplary embodiments of setting tools in connection with Fig. 4 to Fig. 9 The main focus is on the design of the holding elements. For the setting tools according to 4 to 8 The coupling between the tool adapter and the receiving element is corresponding Fig. 3 and for the setting tool according to Fig. 9 accordingly Fig. 1 and 2 executed. Similar or equivalent parts are provided with a reference number that is several hundred times larger than the corresponding reference number in Fig. 1 . The size information for individual components of the setting tool is 10 in Fig. 1 also apply to all other setting tools described.

According to Fig. 4 In a setting tool 210 according to a third exemplary embodiment, a holding element is designed as a cylindrical magnet 230. The magnet 230 is arranged in the guide direction 9 between the recess 224 of the receiving element 214 and the drive-side end. For this purpose, a further recess 232 with a slightly smaller inner diameter, in which the magnet 230 is arranged, adjoins the recess 224 in the direction of the drive-side end. A striking plate 234 adjoins the magnet 230 in the direction of the end 220 facing away from the drive, which is pressed with a metallic safety ring 236 against a shoulder that occurs when the recess 224 transitions to the further recess 232 and is thus secured. The striking plate 234 thus forms a bottom of the recess 224 of the receiving element 214. It is made of hardened steel and protects the Magnet 230 from damage.

According to Fig. 5 In a setting tool 310 according to a fourth exemplary embodiment, the receiving element 314 is designed in several parts. One with the in Fig. 5 The carrier part 339 coupled to the tool adapter, not shown, has an external thread 338 at its end 320 facing away from the drive, which is inserted into a Internal thread 340 of an intermediate piece 342 of the receiving element 314 is screwed in. The intermediate piece 342 has a mainly hollow cylindrical basic shape and is also aligned in the guide direction 9. A striking plate 334 is arranged at the opening of the intermediate piece 342, which is oriented towards the end 320 facing away from the drive. In the area of the aforementioned opening of the intermediate piece 342, the intermediate piece 342 has a slightly larger inner diameter, so that a shoulder results against which the striking plate 334 can be pressed. Inside the intermediate piece 342, towards the drive end, there is a holding element in the form of a cylindrical magnet 330, which is pressed against the striking plate 334 by means of a pressing element in the form of a slightly pre-tensioned coil spring 344. The coil spring 344 is supported on the one hand on the magnet 330 and on the other hand on the carrier part 339.

The intermediate piece 342 has an external thread 346 at its end oriented in the direction of the drive away from the drive, which is screwed into an internal thread 348 of an end piece 350 which adjoins the intermediate piece 342 in the direction of the end 320 facing away from the drive. The end piece 350, together with the striking plate 334, forms the recess 324 of the receiving element 414 and forms the end 320 facing away from the drive. It has an internally circumferential shoulder that presses the striking plate 334 against the aforementioned shoulder of the intermediate piece 342, so that the striking plate 334 is clamped between the intermediate piece 342 and the end piece 350 and is therefore secured.

The intermediate piece 342 and the end piece 350 are made of non-magnetizable material. The striking plate 334, on the other hand, consists of magnetizable material. The pressing element in the form of the coil spring 344 can consist of magnetizable or non-magnetizable material.

The mentioned screw connections between tool adapter 312, intermediate piece 342 and end piece 350 are all secured, in particular glued.

Fig. 6 shows a receiving element 414 of a setting tool 410 according to a fifth exemplary embodiment and a part of an anchor rod 26. The setting tool 410 is very similar to the setting tool 110 according to Fig. 2 built up. The only difference is that the holding element of the receiving element 414 acts as an O-ring 430 is executed. The O-ring 430 is arranged in a circumferential groove in the inner surface of the recess 424 of the receiving element 414. The O-ring 430 can be viewed as an elastic clamping element at least transversely to the guide direction 9, which reduces a cross section of the recess 424 of the receiving element 414 transversely to the guide direction 9. The dimensions of the recess 424, the O-ring 430 and the anchor rod 26 are selected so that an anchor rod 26 inserted into the recess 424 compresses the O-ring 430 so that it exerts a clamping force on the anchor rod 26.

Fig. 7 shows a receiving element 514 of a setting tool 510 according to a sixth exemplary embodiment and a part of an anchor rod 26. The setting tool 510 is very similar to the setting tool 410 according to Fig. 6 built up. The only difference is that the holding element of the receiving element 514 is not designed as an O-ring, but as a metal ring 530. The metal ring 530 has an inner contour through which the force for inserting the anchor bolt 26 into the recess 524 of the receiving element 512 is smaller than a force for pulling the anchor bolt 26 out of the recess 524. This is achieved in that an inner diameter of the metal ring 530 decreases slightly both from the drive-side end and from the end facing away from the drive, and the decrease in the inner diameter at the drive-side end is steeper than at the end facing away from the drive.

Fig. 8 shows a setting tool 610 according to a seventh exemplary embodiment. The holding element 630 is formed by three arms 630a, 630b, 630c which are elastic transversely to the guide direction 9. The arms 630a, 630b, 630c are fastened to the outer surface of the receiving element 614 with two rivets each and form the end 620 of the setting tool 610 facing away from the drive. The arms 630a, 630b, 630c are arranged so that one is arranged in the recess 624 of the receiving element 614 , anchor rod, not shown, presses the arms 630a, 630b, 630c outwards against a tension force.

Fig. 9 shows a receiving element 714 and part of a tool adapter 712 of a setting tool 710 according to an eighth exemplary embodiment and part of an anchor rod 26. The setting tool 710 is very similar to the setting tool 10 according to Fig. 1 built up. The only difference is that the holding element of the Receiving element 714 is formed as an elastic pressing element 730 with a continuous recess 754 in the guide direction 9. An inner diameter of the recess 754 of the pressing element 730 is selected such that the pressing element 730 exerts a pressing force transversely to the guide direction 9 on the anchor rod 26 arranged in the recess 724 of the receiving element 714. The pressing element 730 has a circumferential, inwardly oriented collar 756, which dips into a circumferential groove 758 of the receiving element 714. The pressing element 730 is thus fixed to the receiving element 714.

Fig. 10 shows a receiving element 814 and a part of a tool adapter 812 of a setting tool 810 not included in the scope of protection of the claims and a part of an anchor rod 26. The tool adapter 812 and the receiving element 814 overlap in the tool direction 16 in an overlap area 878. The tool adapter 812 points in the overlap area 878 a mainly cylindrical basic shape and the receiving element 814 has a mainly hollow cylindrical basic shape. An inner diameter of the receiving element 814 is a piece, for example between 4 and 20 mm, larger than an outer diameter of the tool adapter 812. Between the tool adapter 812 and the receiving element 812, a hollow cylindrical coupling element 821 made of elastomer is clamped in the overlap area 878 and thus arranged. The coupling element 821 thus creates a frictional connection between the tool adapter 812 and the receiving element 814. The receiving element 814 also has a holding element 830 corresponding to the holding element 30 in Fig. 1 on.

A method for setting, i.e. for driving in an expansion anchor 28 with an anchor rod 26 into a borehole 60 in a substrate designed as a shaft wall 62 of an elevator shaft 64 is described in connection with Fig. 11 described. To drive in the expansion anchor 28, one of the in the Fig. 1 to 10 the setting tools described are used.

The method is carried out at least partially automatically by an assembly device 66, which can be displaced in the elevator shaft 64 by means of a suspension element 68. The mounting device 66 has a magazine 70 in which a large number of expansion anchors 28 are stored upright. The assembly device 66 can do this Drill a borehole 60 into the shaft wall 62, in particular using a drilling tool (not shown). A robot 72 of the assembly device 66 then picks up an expansion anchor 28 from the magazine 70 using a setting tool 10 inserted into a chuck 74 of a driven impact tool 76. For this purpose, the setting tool 10 is moved from above onto the expansion anchor 28 in such a way that the anchor rod 26 of the expansion anchor 28 is immersed in the recess 24 of the setting tool 10 and the anchor rod 26 is removed from the in the Fig. 10 not shown holding element of the setting tool 10 is held.

After picking up an expansion anchor 28 with the setting tool 10, the expansion anchor 28 and thus the anchor rod 26 are positioned in alignment with the borehole 60 by means of the robot 72. If the expansion anchor 28 and thus the anchor rod 26 are correctly aligned, the driving tool 76 is activated and the expansion anchor 28 is driven into the borehole 60. For this purpose, an impact force applied by the impact tool 76 is transmitted via the setting tool 10 to the anchor rod 26 of the expansion anchor 28. After driving in the expansion anchor 28, the setting tool 10 is pulled off the anchor rod 26. The next expansion anchor can then be driven into a borehole.

Finally, it should be noted that terms such as "comprising", "comprising", etc. do not exclude other elements or steps and terms such as "an" or "an" do not exclude a plurality. Furthermore, it should be noted that features or steps that have been described with reference to one of the above-described exemplary embodiments can also be used in combination with other features or steps of other above-described embodiments. Reference symbols in the claims are not to be viewed as a limitation.
