Description

[0023] Further characteristics and advantages of the invention are evident from the following description and from the following drawings, to which reference is made. In the drawings, the figures show:

[0024] FIG. 1 a setting tool according to the invention,

[0025] FIG. 2 a set according to the invention having multiple setting tools, and

[0026] FIG. 3 a setting tool system according to the invention.

[0027] FIG. 1 shows a setting tool 10 for setting capsule anchors. The setting tool 10 has a shaft 12 and a head 14 arranged at one end of the shaft 12.

[0028] A connection section 16 is arranged on the head 14, wherein the connection section 16 comprises a recess 18. The connection section 16 is particularly formed by the recess 18. The recess 18 is a depression having a hexagonal profile; in particular, the recess 18 has a hexagonal socket geometry.

[0029] In general, the connection section 16 or the recess 18 is arranged in the end face of the head 14, which faces away from the shaft 12.

[0030] An end of the capsule anchor can be inserted into the recess 18, in particular with shape fit, which end is also referred to as a drive head. As a result, a drive torque can be transferred from the setting tool 10 to the capsule anchor. For this purpose, the capsule anchor has a corresponding external hex geometry on an anchor rod, which is coupled with a capsule, as will still be explained below.

[0031] The shaft 12 has a threaded section 20 having a thread 22 and a thread-free section 24. In this regard, the thread-free section 24 can serve to directly connect the setting tool 10 with a drive machine, not shown here. For this purpose, the thread-free section 24 has a hexagonal profile, in particular a hexagon profile, by means of which the setting tool 10 can be coupled with a three-jaw chuck of the drive machine, for example. Alternatively, the thread-free section 24 can also have a quadrangular profile, in particular a square profile.

[0032] By means of the threaded section 20, the setting tool 10 can be connected with an adapter shown in FIG. 2, in particular screwed into it. The adapter is used, above all, if the geometry of the thread-free section 24 does not agree with the geometry of the holder of the drive machine. Furthermore, further functions can be made available by way of the adapter, as will still be explained below.

[0033] The setting 10 accordingly has essentially three regions, namely the connection section 16 at a first end, the threaded section 20 that follows it, as well as the thread-free section 24 at the other end, by way of which the setting tool 10 can be directly connected with a drive machine. These three sections 16, 20, 24 make a transition into one another.

[0034] FIG. 2 shows a set 26 for setting capsule anchors, consisting of an adapter 28 and four different setting tools 10. The recesses 18 of the respective setting tools 10 are configured in different sizes. As a result, each setting tool 10 can be coupled with a specific capsule anchor, which has a size that corresponds to the corresponding recess 18 of the setting tools 10. For example, the setting tools 10 that are shown in FIG. 2 can be coupled with capsule anchors having the thread sizes M8, M10, M12, and M16.

[0035] The shaft 12, in particular the threaded section 20 and the thread-free section 24, can be configured identically in the case of each of the setting tools 10. As a result, all the setting tool 10 can be connected with the one adapter 28.

[0036] In order to connect a setting tool 10 with the adapter 28, the setting tool 10 can be screwed onto the adapter 28 by means of the threaded section 20. For this purpose, the adapter 28 has a thread that corresponds to the threaded section 20 on its holding section 30. This thread is configured as an inside thread, which corresponds to the outside thread of the threaded section 20 of the respective setting tool 10. The thread of the adapter 28 cannot be seen in FIG. 2, since a setting tool 10 is already shown in connection with the adapter 28.

[0037] In this regard, a shape-fit or force-fit threaded connection is produced between the setting tool 10 that is being used and the adapter 28.

[0038] Since the setting tools 10 are coupled with the adapter 28 by way of the corresponding threaded section 20, in each instance, it is sufficient if the threaded sections 20 of the different setting tools 10 are configured to be the same, in each instance. With regard to the thread-free sections 24 of the setting tools 10, it merely has to be ensured that these can be held in the adapter 28.

[0039] At one end of the adapter 28, on which the thread of the adapter 28 is also arranged, the adapter 28 has at least one key surface 32, which is configured as an outside flattened part on the adapter 28. This key surface 32 serves for being able to release the setting tool 10 in simple manner, for example using a corresponding tool.

[0040] The adapter 28 furthermore has an insertion end 34, which is provided on the end that lies opposite the holding section 30. The adapter 28 can be coupled with a drive machine using the insertion end 34. Here, the insertion end 34 is configured as an SDS-Plus insertion end. Optionally, this can also be structured as an SDS-Max insertion end, in particular in order to be able to hold setting tools with which anchor rods having a size of M20 or greater can be set. In this regard, SDS describes an insertion system in which the insertion end 34 is provided with special grooves, which guarantee better transfer of force and, at the same time, percussion. In particular, the insertion end 34 has two longitudinal grooves 36, which extend in the longitudinal direction of the adapter 28 all the way to the end of the adapter 28, at which the insertion end 34 is formed. In FIG. 2, only one of the longitudinal grooves 36 can be seen, since the second longitudinal groove 36 is situated on the opposite side of the adapter 28. The adapter 28 can be inserted into a drive machine with shape fit by means of the longitudinal grooves 36, in accordance with the key/hole principle, and thereby a torque can be transferred from a drive machine to the adapter 28.

[0041] In addition, the adapter 28 has two further grooves 38, provided on opposite surfaces, which grooves have a distance from the end face 40 of the adapter 28 at the insertion end 34. The grooves 38 serve to limit the axial movement of the adapter 28 in a drive machine, in particular during percussion, in that rollers or balls that are mounted in the drive machine engage into the grooves 38. Furthermore, the grooves 38 can contribute to the transfer of torque. FIG. 3 shows a setting tool system 42 having a set 26 according to FIG. 2 or at least one setting tool 10 according to FIG. 1, as well as a capsule anchor 44. The capsule anchor 44 has an anchor rod 46 as well as a capsule 48, in which the at least two components are accommodated.

[0042] The anchor rod 46 has a drive head 50, which is configured as an external hex. Accordingly, the anchor rod 46 can be coupled, by way of the drive head 50, with a correspondingly correspondingly configured setting tool 10, in other words a setting tool 10 having a recess 18 that matches the geometry of the drive head 50.

[0043] In addition, the setting tool system 42 can have a drive machine 52, shown schematically, for example a drill/screwdriver or a hammer drill. The drive machine 52 has a holder 54 for the adapter 28. Alternatively or supplementally, the setting tools 10 can be directly inserted into the holder 54 by way of the respective thread-free section 24.

[0044] In general, first a hole is introduced into a substratum into which the capsule anchor 44 is to be introduced, for example a borehole. Subsequently, this borehole can be cleaned.

[0045] Then the capsule 48 is inserted into the hole to fasten the capsule anchor 44 in place; at least two components are contained in the capsule, which components react with one another if they are mixed with one another. This is implemented in that the capsule anchor 44, in particular its anchor rod 46, is introduced into the borehole that has been provided with the capsule 48, while being rotated, wherein the capsule 48 breaks or tears and releases the at least two components. Due to the rotation of the capsule anchor 44 or of the anchor rod 46, the two components are mixed and react chemically with one another. After the mixture has cured, the capsule anchor 44 is held in the borehole with force fit

[0046] As a function of the borehole and/or of the capsule anchor 44, the corresponding setting tool 10 is used, so that a recess 18 that is suitable for the drive head 50 of the capsule anchor 44 is provided in the selected setting tool 10.

[0047] Alternatively to separate configuration of the anchor rod 46 and of the capsule 48, the capsule 48 can also be arranged integrally on the anchor rod 46, so as to form an integral capsule anchor 44.
