It is already a fastening and / or connecting device with at least one longitudinal element, which is limp at least in sections

trained has been proposed. The object of the invention is in particular to provide a generic device with advantageous properties with regard to efficiency,

in particular to use efficiency. The task is

according to the invention by the features of claims 1 and 22 to 26 solved, while advantageous refinements and developments of the invention can be found in the dependent claims.

Advantages of the invention

The invention is based on a fastening and / or connecting device with at least one longitudinal element, which is formed limp at least in sections, preferably continuously, in particular along a longitudinal direction of the longitudinal element.

It is proposed that the longitudinal element has an external thread, at least along a large part of an entire longitudinal extent of the longitudinal element, in particular, it is introduced directly into the longitudinal element. In this way, in particular advantageous properties with regard to efficiency, in particular usage efficiency, can be provided. In particular, a high material utilization efficiency can be achieved by, for example, a

Longitudinal element can be cut to the required length directly at an installation location without producing waste or waste. This can advantageously necessitate storage for different lengths of time

Fastening and / or connecting devices are at least largely eliminated. It is advantageously possible to screw on a nut or a further screw element at the ends of the longitudinal element regardless of a length of the longitudinal element and / or an elongation of the longitudinal element due to the external thread extending at least along a large part of the entire longitudinal extent of the longitudinal element. In addition, any position of a nut screwed onto the longitudinal element and / or of a further screw element in the longitudinal direction of a longitudinal element can advantageously be made possible. In addition, the longitudinal element has in particular in one

A high advantage compared to a conventional steel rod anchor

Flexibility, whereby in particular transport, storage and / or handling, in particular assembly, can be facilitated. For example, an insertion into the longitudinal element in a borehole is much easier because of a parallel alignment of the entire longitudinal element with the extension of the borehole before insertion can advantageously be omitted. In particular, only a part of the longitudinal element located directly in front of the borehole has to be aligned. In addition, a good positive fit of the longitudinal element with a concrete and / or a mortar can advantageously be achieved by the external thread extending along a large part of the entire longitudinal extent of the longitudinal element, which is introduced together with the longitudinal element into a borehole. This can advantageously achieve a high pull-out strength of the longitudinal element in the borehole. In addition, an assembly of a threaded sleeve, for example crimped onto a longitudinal element, for example a wire rope or the like, can advantageously be omitted. Which can advantageously reduce assembly time and effort. In addition, a possible weak point, the crimp or press connection of the threaded sleeve, can advantageously be avoided by dispensing with the separate threaded sleeve. The screw element is designed in particular as a nut, the nut being able to carry, for example, an eyelet (for example a ring nut), a fork or a coupling (for example a coupling nut).

A “fastening and / or connecting device” is to be understood in particular as a device which is at least intended to attach and / or attach an object to a further object and / or which is at least intended to connect at least two objects to one another and / or to unite into a structure. A “longitudinal element” is to be understood in particular as an element which has a substantially greater extension in a longitudinal direction of the longitudinal element than all other directions of extension of the longitudinal element. In particular, the extension of the longitudinal element in the longitudinal direction is at least 5 times, preferably at least 10 times, advantageously at least 50 times, preferably at least 100 times and particularly preferably at least 1000 times longer than a maximum extension of the longitudinal element in one to the longitudinal direction vertical direction. In particular, the longitudinal direction of the longitudinal element forms a main direction of extension of the longitudinal element. Under one

The “main direction of extension” of an object is to be understood in particular as a direction that runs parallel to a longest edge of a smallest geometric cuboid that just completely surrounds the object. In particular, the longitudinal element is designed as at least one at least substantially flexible rod, as a bundle of at least substantially flexible rods, preferably thread-like or preferably rope-like, in particular wire-rope-like. In particular, the longitudinal element has an at least substantially round and / or oval cross section. In particular, an overall diameter of a cross section of the longitudinal element is at least 10 mm, preferably at least 15 mm, advantageously at least 20 mm, preferably at least 30 mm and advantageously at most 40 mm.

The phrase “at least in sections bend-limp” is to be understood in particular to mean that at least one or at least a plurality of

Sections of the longitudinal element are formed limp. It is

For example, it is conceivable that limp and rigid areas, in particular regularly, alternate along the longitudinal extent of the

Alternate longitudinal elements, preferably with an external thread

is arranged at least one pliable section or a plurality of pliable sections. However, the entire longitudinal element is preferably designed to be limp with an at least substantially constant bendability of the longitudinal element along the longitudinal direction of the longitudinal element.

“Bend-limp” should in particular be understood to have a high degree of flexibility, is dimensionally unstable and / or dimensionally unstable. In particular, a limp object has a low modulus of elasticity (preferably less than 190 kN / mm ² ). In particular, the slack longitudinal element is already experiencing great

Deformations, in particular in a direction perpendicular to the longitudinal direction of the longitudinal element, as a result of low force and moment loads, in particular in the direction perpendicular to the longitudinal direction of the longitudinal element,

for example by forces which are substantially less than 10%, preferably are less than 50% and preferably less than 100% of a total weight of the longitudinal element. In particular, the slack longitudinal element is not intended to transmit torques or transverse forces.

A “large part” is to be understood in particular to mean at least 51%, preferably at least 65%, advantageously at least 75%, preferably at least 85% and particularly preferably at least 95%. Under a

External thread is to be understood in particular as a thread which has at least one thread, preferably at least a plurality of adjoining threads, which preferably

spiral in a circumferential direction of the longitudinal element, around the longitudinal element. In particular, the external thread forms a bolt thread. In particular, the external thread has an at least essentially round and / or oval cross section. In particular, the external thread is in

Circumferential direction of the longitudinal element is formed all the way round. Alternatively, the external thread can only run in sections, i.e. interrupted at least in sections, be formed. Including that

External thread “introduced directly into the longitudinal element” should in particular be understood to mean that the external thread, in particular the threads of the external thread, are formed in one piece with the longitudinal element.

A surface of the longitudinal element preferably forms a shape of a thread directly. In particular, the longitudinal element is free of threaded sleeves pressed and / or crimped onto the longitudinal element. In particular that is

External thread designed as a right-hand thread or as a left-hand thread. Alternatively, it is conceivable that sections with right-hand threads and with left-hand threads are arranged alternately along the longitudinal element. In particular, the external thread has a constant thread pitch. Alternatively, the longitudinal element can have sections with varying thread pitches.

This can advantageously be adapted to different nuts and / or screw elements, in particular by cutting the longitudinal element to a certain point depending on the desired fit. In one aspect of the invention, which taken on its own or in combination with at least one, in particular in combination with,

Aspect of the invention, in particular in combination with any number of the other aspects of the invention, it is proposed that the longitudinal element at least in an end region of the longitudinal element, preferably at least along a large part of an entire longitudinal extent of the

Longitudinal elements, has an external thread introduced directly into the longitudinal element with a plurality of threads, at least one thread of the external thread, in particular each thread of the external thread, being interrupted at least in sections and / or at least substantially flattened. This advantageously enables simple production of the thread. In addition, material stress, in particular during a thread production process, for example by pressing the material of the longitudinal element, can advantageously be kept low. In addition, an interrupted thread advantageously permits simplified, orderly rolling up of the longitudinal element onto a bobbin, in particular by making flattened areas or areas without a thread contact one another in a state of the longitudinal element rolled up on the bobbin. In particular, the at least one thread of the external thread, preferably each thread of the external thread, is interrupted and / or flattened at least twice, in particular at least three times or more than three times. In particular, areas in which the threads of the external thread are interrupted and / or flattened are arranged opposite one another in a radial direction of the longitudinal element. In particular, areas in which adjacent threads of the

External thread are interrupted and / or flattened, at least in

Arranged essentially on the same sides of the longitudinal element. Alternatively, the areas in which adjacent threads of the external thread are interrupted and / or flattened can be arranged offset to one another in the circumferential direction of the longitudinal element. It is also proposed that the external thread be designed as a coarse thread and / or as a round thread. A particularly high robustness of the external thread can thereby advantageously be achieved, in particular in that the thread has few sensitive and / or filigree edges or is preferably free of sensitive and / or filigree edges. In addition, a round thread, in particular a coarse round thread, is advantageously insensitive to contamination, which is particularly the case when mounting in

Outside, for example on a construction site, is advantageous. A coarse thread also advantageously allows quick assembly. In addition, cleaning a coarse thread, in particular a coarse round thread, is particularly simple due to the increased gaps between the flanks of the thread

External thread. In addition, by avoiding sharp edges,

especially pointed inner edges, advantageously a risk of damage to a longitudinal element made of high-strength steel wire can be kept low. Due to its strength, high-strength steel wire in particular has an increased risk of breaking at pointed edges. Furthermore, due to the lack of corners and edges in the round thread, good corrosion protection can advantageously be achieved, especially since corners and edges are often subject to greater corrosion than flat or curved surfaces. In addition, a tendency to seize of a screw element screwed onto the longitudinal element, for example a nut, can advantageously be kept low. It can be advantageous for the screwed onto the longitudinal element

Screw element, in particular by an undesirable cold welding, are at least substantially prevented, especially since in one

Round thread hardly any plane-parallel contact surfaces between the

Screw element and the longitudinal element exist, which can favor cold welding. This is particularly advantageous in the case of at least partial formation of the screw element and / or the longitudinal element, in particular the external thread, of stainless steel and / or in the case of installation under particularly dirty, in particular muddy, environmental conditions, since stainless steel, in particular contaminated stainless steel, has an increased tendency to seize, in particular in comparison with a steel other than stainless steel.

In particular, the round thread seen in a thread profile has a radius of curvature of a surface of the external thread around a thread tip of the external thread of at least 0.5 mm, preferably at least 1 mm, advantageously at least 2 mm, particularly advantageously at least 3 mm, preferably at least 5 mm and particularly preferably at most 10 mm on.

In particular, there is a difference between an outside diameter of the outside thread, in particular a diameter of thread tips of the outside thread, and an inside diameter of the outside thread,

in particular a thread core diameter of the thread base of the

External thread, at least 5%, preferably at least 8%, advantageously at least 10%, particularly advantageously at least 12%, preferably at least 15% and particularly preferably at least 20% of an external diameter of the external thread. In particular, there is a difference between one

Outside diameter of the external thread, in particular a diameter of thread tips of the external thread, and an inside diameter of the

External thread, in particular a thread core diameter of

Thread root of the external thread, at most 35%, preferably at most 30%, advantageously at most 25%, preferably at most 20% and particularly preferably at most 15% of an external diameter of the external thread.

As a result, a particularly firm hold of a nut screwed onto the external thread can be advantageously achieved while the external thread is highly robust and the nut can be screwed easily along the external thread. In addition, a high pull-out strength of the longitudinal element from a nut or from a further screw element which is screwed onto the external thread can advantageously be achieved. In particular, a pitch angle of a thread flank of the external thread is at least 20 °, preferably at least 25 °, advantageously at least 30 °, preferably at least 35 ° and particularly preferably at most 45 °. Alternatively, the thread flank, for example in the case of a round thread, can be continuously curved and / or free of straight lines and / or be flat sections. This can advantageously be a high

Pull-out strength of the longitudinal element from a nut or from a further screw element which is screwed onto the external thread can be achieved. In particular, the external thread has a symmetrical thread profile. Alternatively or additionally, the external thread can have an asymmetrical external thread at least in sections. In particular, a distance between thread tips of adjacent thread turns is at least 30%, preferably at least 40%, advantageously at least 50%, preferably at least 75% and particularly preferably at least 100% of the external diameter of the external thread.

It is also proposed that the longitudinal element alternately have sections with an external thread and sections without an external thread along the majority of the entire longitudinal extent of the longitudinal element. As a result, high manufacturing efficiency can advantageously be achieved, in particular by optimizing the effort involved in producing the external thread. In particular, the longitudinal element has at least three sections

External threads, preferably at least more than three sections

External threads. In particular, at least one section with a

External threads are arranged at each end region of the longitudinal element.

In particular, at least one section with an external thread is arranged in a central region of the longitudinal element. In particular, the sections with external thread and the sections without external thread have at least in

Essentially equal lengths. Alternatively, you can use the sections

External thread and the sections without external thread have different lengths. In particular, the sections with external threads are regularly spaced apart. Alternatively, the sections with an external thread can be spaced irregularly or randomly from one another. In particular, it is conceivable that the sections with an external thread are different

Have thread pitches, different thread shapes or different thread directions. Suitability for different nuts and / or further screw elements are made possible. However, the sections with an external thread preferably have at least one

Essentially identical thread pitches and / or at least substantially identical thread shapes or an identical thread direction. “Essentially identical” should be understood to be identical, particularly in the context of manufacturing tolerances.

It is also proposed that the longitudinal element is at least partially, preferably completely, made of a high-strength steel, which in particular has a tensile strength of at least 800 N / mm ² , preferably at least 1000 N / mm ² , advantageously at least 1200 N / mm ² , particularly advantageous 1400 N / mm ² , preferably at least 1770 N / mm ² and particularly preferably at most 2500 N / mm ² . As a result, high stability and high efficiency, in particular material efficiency, can advantageously be achieved. A material saving can be advantageously achieved, in particular when compared to commercially available structural steel threaded rods, while at the same time maintaining usability and a comparable or higher overall tensile strength. Rigid threaded rods are usually made of steel with a nominal tensile strength of 500 N / mm ² , since in particular brittleness and / or brittleness of massive rigid rigid threaded rods with a steel of higher tensile strength is too great. A risk of breakage of the proposed limp fastening and / or connecting device made of high-strength steel is advantageously less than a risk of breakage of rigid threaded rods made of comparable steel. A material saving can be advantageous

Weight reduction can be achieved, whereby in particular handling of the fastening and / or connecting device can be facilitated and / or simplified. In addition, a material saving can advantageously enable a, in particular comparatively, lower environmental impact, in particular by advantageously reducing the amount of steel required for a specific fastening and / or connection task, as a result of which a C0 ₂ footprint can advantageously be reduced. Can be advantageous by a Material savings a diameter of the longitudinal element while maintaining an overall tensile strength compared to a rigid rod from a commercially available material with a tensile strength of 500 N / mm ² can be reduced, which in particular when anchoring the longitudinal element in one

Borehole advantageously a necessary borehole diameter can be reduced.

This can advantageously reduce the cost of masterwork, such as making the drill holes and / or a glue and / or mortar requirement for anchoring the longitudinal elements in the drill holes, thereby advantageously reducing costs and an installation speed of the fastening and / or connecting device can be increased.

 In particular, the high-strength steel is designed as a carbon steel and / or as a high-strength rust-bearing steel. The fact that the longitudinal element “is formed at least partially from the high-strength steel” should in particular be understood to mean that at least a section of the longitudinal element or at least a partial element, in particular a single longitudinal element, of the

Longitudinal elements made of high-strength steel.

Furthermore, it is proposed that the longitudinal element be wound onto a bobbin, in particular with a smallest winding diameter of at most 15 times, preferably at most 20 times, advantageously at most 25 times, preferably at most 35 times and particularly preferably at most 45 times an external diameter of the external thread, can be rolled up. As a result, high transport efficiency can advantageously be achieved. Good transportability can advantageously be achieved,

especially in comparison to rigid longitudinal elements, in particular

Threaded rods. A transport of fastening and / or connecting devices with particularly long longitudinal elements can advantageously be made possible. In particular, bobbins with coiled longitudinal elements of lengths over 1000 m are conceivable. In addition, a simple one can be advantageous

The longitudinal elements can be assembled, in particular by only unrolling a required length of the longitudinal element from the bobbin and is cut to length. The “smallest winding diameter” of a bobbin is intended in particular to mean an outer diameter of a winding element of the bobbin

be understood by which the longitudinal element is rolled onto the bobbin in an at least partially rolled-up state. In particular, the smallest winding diameter of the bobbin corresponds to a minimum radius of curvature of the longitudinal element when rolled up. Under the "external diameter of the external thread" in particular a maximum diameter of the

Longitudinal elements in a sectional plane that is perpendicular to the longitudinal direction of the longitudinal element can be understood. In order to be “rollable” onto the bobbin, the longitudinal element must have a bendability which is one

interference-free bending of the longitudinal element with a bending radius which corresponds approximately to the smallest winding diameter. An “interference-free bend” is to be understood in particular as a bend which excludes damage or irreversible plastic expansion or plastic deformation of the longitudinal element or a partial component of the longitudinal element. Damage can be, for example, permanent re-sorting of sub-components of the longitudinal element, in particular individual longitudinal elements of the longitudinal element, in which the partial components of the longitudinal element, in particular the individual longitudinal elements of the longitudinal element, protrude partially or in sections from a surface of the longitudinal element after the longitudinal element has been unrolled and straightened and / or at which threads of the external thread are permanently shifted after rolling and / or straightening the longitudinal element. Preferably, the threads of the external thread of the longitudinal element after rolling off the longitudinal element are at least substantially identical to the threads of the external thread of the longitudinal element before rolling up the longitudinal element. Alternatively, the longitudinal element can also be brought into a ring and / or spiral shape and / or wound independently of a bobbin. As a result, an overall transport weight of the longitudinal element can advantageously be kept low. It is further proposed that the longitudinal element have a total length of more than 12 m, preferably at least 15 m, preferably at least 25 m and particularly preferably at least 100 m. It is also conceivable that the longitudinal element has a length of one or more kilometers. As a result, high assembly efficiency can advantageously be achieved,

in particular, in that a coupling of several separate longitudinal elements, for example threaded rods, which are only available up to a maximum length of 12 m due to transport restrictions for trucks, can advantageously be omitted to achieve a length greater than 12 m. This can advantageously be a simple handling of the fastening and / or

Connecting device, especially compared to rigid

Threaded rods can be reached. In addition, time can advantageously be saved during assembly, as a result of which assembly costs can advantageously be reduced. In addition, with an insertion of the more than 12 m long longitudinal element into a more than 12 m deep borehole, there is advantageously no need for laborious and complex alignment of the longitudinal element relative to an extension of the borehole, as is necessary with long coupled, rigid rigid threaded rods. This is particularly true of boreholes in

difficult, for example sloping terrain, considerable time, cost and labor savings.

In addition, it is proposed that the longitudinal element have an outer diameter which is at least 15%, preferably at least 20%, preferably at least 25% and particularly preferably at least 35% smaller than an outer diameter of a rigid rod, in particular threaded rod, made of structural steel an at least substantially equal overall tensile strength. This can advantageously be a high

Material use efficiency can be achieved, which in particular a

Weight reduction, a reduced environmental impact and / or

simplified handling can be made possible. The rigid rod is in particular as a threaded rod, as a rebar, as one Reinforcing bar, designed as a mounting bar or as a reinforcing bar. Under "structural steel" steel in particular should have a tensile strength in a range from 340 N / mm ² to 510 N / mm ² , with a yield strength in a range from 185 N / mm ² and 355 N / mm ² , with a shear modulus of

81000 N / mm ² and / or with an elastic modulus of at least 215 GPa. In this context, “at least essentially the same” is to be understood in particular to mean that there is a deviation in the overall tensile strengths of the longitudinal element and the rigid rod

is in particular less than 10%, preferably less than 5% and particularly preferably less than 2%. In particular, the longitudinal element has a diameter of at least 5 mm, preferably at least 10 mm, advantageously at least 20 mm, preferably at least 30 mm and particularly preferably at most 40 mm.

It is also proposed that the longitudinal element have a modulus of elasticity of at most 190 kN / mm ² , preferably at most 170 kN / mm ² , preferably at most 150 kN / mm ² and particularly preferably at most 130 kN / mm ² . This can advantageously be a high flexibility of the longitudinal element, in particular without damage and / or without irreversible plastic

Deformation can be achieved. This advantageously shows

Longitudinal element has a ductility greater than 1%, preferably greater than 2%, advantageously greater than 3%, particularly advantageously greater than 4%, preferably greater than 5% and particularly preferably less than 6%.

If the longitudinal element comprises at least a plurality of individual longitudinal elements formed separately from one another, in particular an advantageously high bendability and / or an advantageously high extensibility of the longitudinal element can be achieved. In particular, the individual longitudinal elements form a composite, which is held together, for example, by braiding, knotting, gluing, welding and / or tying together, in particular by means of sleeves, bands or the like. In particular, the

Individual longitudinal elements an at least substantially straight, preferably rod-shaped, outer shape or a turned and / or twisted, preferably spiral-shaped outer shape. In particular, the longitudinal element comprises at least seven, preferably at least 19, advantageously at least 37, preferably at least 61 and particularly preferably at least 91 individual longitudinal elements.

In particular, the individual longitudinal elements are designed as wires made of high-strength steel. In particular, the individual longitudinal elements of the longitudinal element have at least substantially identical cross sections and / or diameters. Alternatively, at least some of the individual longitudinal elements of the longitudinal element can have cross sections and / or diameters that differ from one another.

For example, a diameter of external and internal individual longitudinal elements can differ significantly from one another. In particular, a single longitudinal element has a diameter of at least 0.5 mm, preferably of at least 1 mm, advantageously of at least 2 mm, particularly advantageously of at least 3 mm, preferably of at least 5 mm and particularly preferably of at most 7 mm. In particular, a cross-sectional area is one

Individual longitudinal elements at least 0.2 mm ² , preferably at least 0.79 mm ² , advantageously at least 5 mm ² , particularly advantageously at least 10 mm ² , preferably at least 20 mm ² and particularly preferably at most 40 mm ² . In particular, a metallic cross section of the longitudinal element is at least 60 mm ² , advantageously at least 150 mm ² , particularly advantageously at least 300 mm ² , preferably at least 500 mm ² and particularly preferably at most 1200 mm ² .

It is also proposed that the individual longitudinal elements are stranded together. As a result, high flexibility and / or high flexibility can advantageously be achieved

Elongation of the longitudinal element can be achieved. In addition, a high robustness of the longitudinal element against damage can advantageously be achieved, in particular by a crack in the longitudinal element advantageously only one

Single longitudinal element or only a part of the individual longitudinal elements, whereby a risk that a crack spreads over the entire longitudinal element can be kept low. A weakening of the longitudinal element consisting of stranded individual longitudinal elements by a crack is particularly advantageous of a single longitudinal element locally limited to one to two lay lengths of the longitudinal element. In comparison to a solid threaded rod, a steel with a higher tensile strength can advantageously be used with a wire rope without producing too great a brittleness. In particular, a longitudinal element consisting of stranded individual longitudinal elements has little, in particular in a comparison with a solid, straight longitudinal element

Young's modulus, preferably less than 190 kN / mm ² . In particular, the individual longitudinal elements stranded together form the longitudinal element, preferably a wire rope, and / or at least one strand of the longitudinal element, preferably the wire rope. The individual longitudinal elements are preferably tied to the wire rope and / or to a strand of the wire rope. Alternatively or additionally, the individual longitudinal elements are interwoven to form a wire rope. In particular, the fact that individual longitudinal elements are "stranded together" should

be understood that the individual longitudinal elements are twisted together, twisted against each other and / or at least essentially helically wound around each other. In particular, the wire rope formed from the individual longitudinal elements has a lay length which is at least 4 times, preferably at least 8 times, advantageously at least 12 times, particularly advantageously at least 16 times, preferably at least 22 -fold and particularly preferably at least 30 times larger than an average diameter of the longitudinal element.

In addition, it is proposed that the wire rope formed from the individual longitudinal elements has a lay angle of less than 25 °, preferably less than 20 °, advantageously less than 15 °, preferably less than 10 ° and particularly preferably at least 5 °. A particularly advantageous external thread shape can thereby advantageously be achieved, in particular by

Single longitudinal elements at least in the thread of the external thread

Cross essentially vertically. In this context, the expression “essentially perpendicular” is intended in particular to define an orientation of a direction relative to a reference direction, the direction and the reference direction, viewed in particular in one plane, enclose an angle of 90 ° and the angle has a maximum deviation of in particular less than 20 °, advantageously less than 15 ° and particularly advantageously less than 10 °.

As a result, particularly good movement of the external thread can advantageously be achieved when a nut is screwed on. Alternatively, however, it is also conceivable that the wire rope formed from the individual longitudinal elements has a lay angle of more than 25 °.

The wire rope formed from the individual longitudinal elements is in particular a stranded wire rope, for example a 6x7 stranded wire rope, a 7x7 stranded wire rope, a 6x19 stranded wire rope, a 7x19 stranded wire rope, a 6x31 stranded wire rope, a 6x37

Stranded wire rope and / or a 7x37 stranded wire rope. In particular, the stranded wire rope is as a Seale stranded wire rope, as a Warrington stranded wire rope, as a Seale-Warrington stranded wire rope and / or as one

Stranded wire rope designed with cored wires. In particular, this points as

Stranded wire rope formed a right or left wire rope

 Same strike or preferably a right or left cross strike.

However, the wire rope formed from the individual longitudinal elements is preferably in the form of a spiral wire rope, for example a 1 × 7 spiral wire rope, in particular a single-ply (1 +6) spiral wire rope, as a 1 × 19 spiral wire rope, in particular a two-ply (1 + 6 + 12) spiral wire rope as one 1 x37 spiral wire rope, in particular a three-layer (1 + 6 + 12 + 18) spiral wire rope, as a 1 x61 spiral wire rope, in particular a four-layer (1 + 6 + 12 + 18 + 24) spiral wire rope and / or as a 1x91 spiral wire rope, in particular a five-layer (1 + 6 + 12 + 18 + 24 + 30)

Spiral wire rope formed. Alternatively, the wire rope formed by the individual longitudinal elements can also be a fully closed rope, for example a single-layer, a two-layer or a multi-layer fully closed rope

Spiral wire rope, be formed.

In addition, it is proposed that the longitudinal element have at least two, preferably at least three, and in particular at most five, stranding layers has a core longitudinal element of the longitudinal element. As a result, high flexibility and / or high extensibility of the longitudinal element can advantageously be achieved. In addition, a high level of robustness of the longitudinal element can advantageously be achieved, in particular by breaking or tearing an individual longitudinal element of the longitudinal element only by a slight reduction in the load-bearing capacity of the

Longitudinal elements. In particular, the longitudinal core element is designed as a cable core. In particular, the core longitudinal element is at least substantially identical to the individual longitudinal element and / or to a strand made of individual longitudinal elements. Alternatively, the core longitudinal element can be one of the individual longitudinal element or the strand made of individual longitudinal elements

have a different diameter, which is preferably larger than the diameter of the individual longitudinal element or the strand of individual longitudinal elements. In addition, the core longitudinal element can alternatively consist of a different material than the individual longitudinal elements, for example the core longitudinal element can be used as an insert made of an elastic material, e.g. Plastic. In addition, the core longitudinal element could alternatively be hollow.

In particular, the stranding layers have at least substantially identical lay angles and / or lay lengths. Alternatively, at least one

Stranded layer a lay angle deviating from a further stranded position and / or a lay length deviating from a further stranded position

exhibit.

It is also proposed that at least two of the stranding layers of the

Longitudinal elements are twisted crosswise to compensate for torque. A high level of security can thereby advantageously be achieved. In addition, an excessively large change in diameter of the longitudinal element under tensile loading can be prevented by rotating the individual stranding layers in the same direction, as a result of which a particularly constant and / or load-independent diameter of the longitudinal element can advantageously be achieved. This can advantageously a good hold on the external thread of the

Longitudinal screwed nut and / or one on the external thread the screwed-on further screw element can also be ensured under a load on the longitudinal element. A reduction in the hold of the nut or the further screw element can advantageously be prevented. In particular, all of the stranding layers of the longitudinal element are stranded alternately crosswise to compensate for torque. “Cross-stranding” is to be understood in particular to mean that individual longitudinal elements of spiral wire ropes and / or strands of stranded wire ropes of adjacent stranding layers form spirals with different starts. In particular, the stranding layers of the longitudinal element, twisted crosswise to compensate for torque, alternately form left-handed and

right-handed helices.

Furthermore, it is proposed that at least one separating element is arranged at least between two stranding layers. As a result, a high level of security can advantageously be achieved, in particular by preventing direct friction between the individual longitudinal elements and / or strands of adjacent stranding layers and / or by increasing corrosion protection of the individual longitudinal elements and / or strands of adjacent stranding layers. In particular, this can cause electrochemical voltage corrosion between

Individual longitudinal elements and / or strands of adjacent stranding layers are prevented, in particular if the individual longitudinal elements and / or strands

Adjacent stranded layers have surface materials with a different standard electrode potential, for example if an inner stranded layer is made of high-strength carbon steel and one

external stranding layer made of rust-resistant steel (INOX). The separating element is designed in particular as a sheathing of at least one individual longitudinal element, at least one strand and / or an entire stranding layer.

The separating element is preferably electrically insulating and / or non-conductive, for example at least partially made of a plastic. In particular, a separating element is arranged at least between the outermost stranding layer and the stranding layer adjacent to the outermost stranding layer. It is conceivable that in particular at least one separating element is arranged between more than two stranding layers. A separating element is preferably arranged between all the stranding layers. It is also conceivable that, in particular, a plurality of separating elements is arranged between at least two stranding layers. The separating element forms, in particular, a separating layer separating the twisted layers.

If different individual longitudinal elements, in particular individual longitudinal elements belonging to different stranding layers, have tensile strengths that are at least substantially different from one another, an overall tensile strength and at the same time an external thread shape can advantageously be optimized. In particular, a high overall tensile strength can advantageously be achieved while at the same time enabling an advantageous external thread shape, for example with a sufficient depth of the thread root. In particular, individual adjacent individual longitudinal elements of a stranded layer of a spiral wire rope have tensile strengths which are at least substantially different from one another, or all individual longitudinal elements of a stranded layer have an at least in the

Essentially identical tensile strength, which differs at least substantially from a tensile strength of at least part of the longitudinal elements, in particular all longitudinal elements, of adjacent stranding layers. The fact that tensile strengths “essentially differ from one another” is to be understood in particular to mean that the tensile strengths form a difference of at least 10%, preferably at least 25% and preferably at least 50%.

In addition, it is proposed that at least some of the individual longitudinal elements, which form an outer stranded layer, have a tensile strength that is significantly lower than an average tensile strength of

Single longitudinal elements, which form an internal stranding layer. This advantageously allows good shapability of the outer stranding layer for producing an external thread, in particular while maintaining a high overall tensile strength of the longitudinal element. Under one “Significantly lower tensile strength” should in particular be understood to mean a tensile strength which is at least 10% lower, preferably one which is at least 25% lower, preferably one which is at least 50% lower and particularly preferably one which is at least 75% lower. In particular, the

external stranding layer with the lower tensile strength has at least a tensile strength of 500 N / mm ² , preferably of at least 750 N / mm ² , preferably of at least 1000 N / mm ² and particularly preferably of at least 1250 N / mm ² . In particular, the individual longitudinal elements have internal and

external stranding layers are significantly different from each other

Tensile strengths, but the individual longitudinal elements on the inside as well as the individual longitudinal elements on the outside of the stranding layers are made of high-strength steel.

It is further proposed that at least some of the individual longitudinal elements have an at least partially round cross section and / or at least some of the individual longitudinal elements have an at least partially polygonal, in particular triangular, rhomboid, biconcave lens-shaped and / or Z-shaped,

Has cross section. This enables an advantageous rope pack to be achieved. In particular, at least a part of the individual longitudinal elements of the

Longitudinal elements, in particular all individual longitudinal elements of the longitudinal element, have a completely round cross section. In particular, at least the individual longitudinal elements of the outer stranding layer and / or the

Individual longitudinal elements of the stranding layer adjacent to the outer stranding layer, at least in sections, preferably at least on those adjacent to the thread root of the external thread of the longitudinal element

Subregions of the individual longitudinal elements, a cross-section deviating from a round cross-section, which in particular has a cross-section at least in

Essentially rectangular shape with a part-circular elevation or

Indentation on an inner side of the single longitudinal element. In particular, a fully closed spiral wire rope has at least in the outer stranded position and / or in the outer stranded position adjacent stranded layer individual longitudinal elements with a rhomboid or a Z-shaped cross-section.

It is also proposed that at least a part of the longitudinal element, in particular at least a part of the individual longitudinal elements of the longitudinal element, have a corrosion protection layer or be made of stainless steel. As a result, high corrosion resistance can advantageously be achieved, which can advantageously lead to a long service life. In particular, the corrosion protection layer is in the form of a zinc coating, a zinc-aluminum coating, for example a Galfan coating, a zinc-aluminum coating with an additive, for example magnesium and / or a coating, for example a polymer, epoxy and / or

Plastic sheath, trained. The corrosion protection layer is preferably at least partially designed as an active corrosion protection layer, which in particular forms an anodic corrosion protection. It is also conceivable for the corrosion protection layer to comprise a plurality, in particular superimposed coatings, in particular with different material properties of at least one layer. Alternatively and / or additionally, it is conceivable that the corrosion protection layer at least partially as a passive corrosion protection layer and / or a cathodic one

Corrosion protection layer is formed. Preferably, the

Corrosion protection layer at least meets the requirements in DIN EN 102064-2: 2012-3 for a minimum quantity of a coating with a corrosion protection layer for class A wires. In particular, at least the

Single longitudinal elements of the outer stranded layer one

Corrosion protection layer on or are made of stainless steel (INOX). All individual longitudinal elements preferably have one

Corrosion protection layer on or are made of stainless steel (INOX). In particular, individual longitudinal elements of inner and outer stranding layers have different corrosion protection, in particular corrosion protection layers of different thicknesses and / or differently composed corrosion protection layers. For example, the individual longitudinal elements of the outer stranding layer are made of stainless steel, while the individual longitudinal elements of the inner stranding layers are a corrosion protection layer, for example a zinc coating or a

Galfan coating. This advantageously allows corrosion-protected individual longitudinal elements of different materials and / or tensile strengths to be combined in the longitudinal element. It is conceivable that a thickness of an anti-corrosion layer of an individual longitudinal element decreases, the further inside the longitudinal element is arranged in the longitudinal element. Material costs can thereby advantageously be kept low.

It is also proposed that at least some of the individual longitudinal elements of the longitudinal element, which form an outer stranding layer, are made of stainless steel and that at least a further part of the individual longitudinal elements of the longitudinal element, which form an inner stranding layer, are made of carbon steel. This advantageously enables corrosion-protected individual longitudinal elements of different materials and / or tensile strengths to be combined in the longitudinal element, which advantageously also enables the overall tensile strength, the corrosion resistance and the material costs to be optimized. In particular, they show

Carbon steel inner layers have an additional corrosion protection layer on the surface. A “carbon steel” is to be understood in particular as meaning a steel with an increased carbon content, which is in particular at least 0.5%, preferably at least 0.7%, preferably at least 0.9% and particularly preferably at most 1%. An “outer stranding layer” is in particular in the form of a stranding layer which only adjoins another stranding layer and / or a rope core on one side. An “inner stranding layer” is designed in particular as a stranding layer, which adjoins another stranding layer and / or a rope core on both sides. Furthermore, it is proposed that the longitudinal element, in particular at least one individual longitudinal element of the longitudinal element, have at least one

Injection opening, preferably an injection channel. This advantageously allows a flowable material, for example mortar or concrete, to be passed through the longitudinal element along the longitudinal direction of the

Longitudinal elements are made possible. In particular, anchoring the longitudinal element in a borehole can thereby be simplified, in particular by injecting adhesive, for example concrete or mortar, into the injection opening after the longitudinal element has been introduced into the borehole, thereby reaching the end of the borehole and advantageously surrounding the longitudinal element stored around in the borehole. The injection opening, preferably the injection channel, is designed, in particular, as a recess that passes through the longitudinal element, in particular through at least one individual longitudinal element of the longitudinal element, and preferably extends essentially in the longitudinal direction of the longitudinal element. In particular, the injection opening, preferably the injection channel, is assigned to a single longitudinal element.

In particular, the single longitudinal element with the injection opening, preferably the injection channel, is tubular. In particular, the

Injection opening, preferably the injection channel, and / or that

Single longitudinal element with the injection opening, preferably the injection channel, arranged in a center of the longitudinal element. Alternatively or additionally, it is conceivable that the injection opening, preferably the injection channel, and / or the single longitudinal element with the injection opening, preferably the

Injection channel, is arranged outside the center of the longitudinal element. In particular, an injection opening arranged outside the center of the longitudinal element, preferably an injection channel, has one along the

Longitudinally aligned helical course. It is conceivable that at least two or more than two individual longitudinal elements have one

Have injection opening, preferably an injection channel. As a result, a high level of redundancy can advantageously be achieved, in particular by injecting flowable material even in the event of constipation or Damage to one of the injection openings and / or injection channels can be made possible. Alternatively or additionally, at least one

Single longitudinal element, in particular the cable core of the longitudinal element, are dispensed with in order to form the injection opening, in particular the injection channel.

In addition, use of the fastening and / or

Connection device as a rock anchor, in particular strand anchor, for static and / or dynamic loads in foundation and / or civil engineering, for example as a soil and / or rock nail, as a micropile, as

Foundation anchors and / or as rock anchors, and / or as tensioning, connecting and / or holding elements in building construction, for example as tensioning cables and / or as holding elements for glass facades, tent structures and / or

Sun sails suggested. This can be particularly advantageous

Properties with regard to efficiency, in particular usage efficiency, are provided. In particular, this can result in a high

Material use efficiency can be achieved. In addition, a simple assembly of the rock anchor and / or the tensioning, connecting and / or holding element can advantageously be made possible.

In addition, the rock anchor with a fastening and / or

Connection device proposed. A rock anchor of this type, which is more flexible and can be fastened by directly screwing on a nut, is advantageously easy to assemble. Especially since it is a complex one

Aligning the rock anchor parallel to the borehole or complex coupling of separate elements to a rock anchor of a desired length can be omitted. In addition, a limp design of the rock anchor advantageously leads to the fact that transverse loads and / or transverse forces acting on the rock anchor can be converted at least partially, preferably at least to a large extent, into tensile loads. In particular, if a floor in which a rock anchor is anchored slips, for example due to slipping of an uppermost layer of soil, this can lead to shear forces in a rigid construction of a rock anchor, which cause the can damage or destroy rigid rock anchors. This effect can advantageously be reduced when using a limp rock anchor.

Furthermore, a method for assembling a rock anchor is proposed, the rock anchor being unrolled from a bobbin and / or unrolled from a ring shape, cut to any desired length, fastened in a prefabricated receptacle, for example a borehole, and by means of a Screwing a screw element onto the rock anchor is tensioned and / or connected to an object to be anchored. This advantageously enables simple assembly and assembly of the rock anchor.

Furthermore, a manufacturing device for the fastening and / or connecting device with the longitudinal element, which at least

in sections, preferably continuously, in particular along a

Longitudinal direction of the longitudinal element, is formed limp, and which has an external thread over its entire longitudinal extent at least in sections, preferably continuously, the longitudinal element comprising at least a plurality of separate longitudinal elements formed separately from one another, and with a connecting and / or stranding device, which at least for this purpose is provided, in particular continuously, to produce the longitudinal element from the plurality of individual longitudinal elements, and wherein the

Manufacturing device has a threading device, which is arranged directly behind a longitudinal element output of the connecting and / or stranding device and which is provided for this, in particular by means of hot deformation or cold deformation of the longitudinal element, in sections or continuously, the longitudinal element over an entire

To provide the longitudinal extension of the longitudinal element with the external thread.

As a result, high efficiency, in particular manufacturing efficiency, can advantageously be achieved, in particular in that the stranding of the individual longitudinal elements to form the longitudinal element and the production of the external thread of the longitudinal element takes place in two successive steps on the same machine. The phrase "immediately behind" is to be understood in particular at a distance of less than 3 m, preferably less than 1 m and preferably less than 0.5 m. In addition, a method for manufacturing the fastening and / or

The external thread 16a has a plurality of threads 20a, 22a.

The threads 20a, 22a are in the form of spiral depressions

Surface 74a of the longitudinal element 12a is formed. Each thread turn 20a, 22a comprises a thread root 76a. A deepest point of the spiral depression of the thread 20a, 22a forms the thread root 76a. Two adjacent threads 20a, 22a are separated by a thread tip 78a. A highest point of the external thread 16a between two

Threads 20a, 22a form the thread tip 78a. The threaded tip 78a extends spirally along the surface 74a of the longitudinal element 12a. The threads 20a, 22a are formed one after the other. The external thread 16a is continuously formed. The threads 20a, 22a are continuously formed. Alternatively, the external thread 16a and / or the threads 20a, 22a could be at least partially interrupted. The threads 20a, 22a are regularly spaced apart. A distance between two threads 20a, 22a is approximately 50% of an outer diameter 30a of the longitudinal element 12a. The outer diameter 30a of the longitudinal element 12a corresponds to one

Outside diameter 72a of the external thread 16a. The outside diameter 72a of the outside thread 16a is measured between thread tips 78a of the outside thread 16a.

The external thread 16a is designed as a coarse thread. The external thread 16a is designed as a round thread. In a thread profile view, e.g. 1, the thread tips 78a of the threads 20a, 22a are at least substantially round. The rounding of the thread tips 78a of the threads 20a, 22a have one in the thread profile view

In the exemplary embodiment shown in FIG. 1, the pitch angle 86a of the thread flanks 82a, 84a is 30 °. The pitch angle 86a of the right-hand thread flanks 84a and the left-hand thread flanks 82a is at least essentially identical.

The longitudinal element 12a has a modulus of elasticity of at most 190 kN / mm ² .

The longitudinal element 12a comprises a plurality of individual longitudinal elements 28a, 32a. The individual longitudinal elements 28a, 32a are formed separately from one another. The individual longitudinal elements 28a, 32a abut one another on contact. The

Individual longitudinal elements 28a, 32a extend spirally in the longitudinal direction 14a of the longitudinal element 12a. Alternatively, the individual longitudinal elements 28a, 32a can also extend straight in the longitudinal direction 14a of the longitudinal element 12a. The individual longitudinal elements 28a, 32a are stranded together. The longitudinal element 12a forms a wire rope 34a. The wire rope 34a shown in Fig. 1 is as one

Spiral wire rope formed. Alternatively, the wire rope 34a could be as one

Stranded wire rope should be formed. A spiral wire rope advantageously allows better threading due to a more flat surface 74a in comparison to a stranded wire rope. The individual longitudinal elements 28a, 32a stranded together are free of additional connecting means such as sleeves, adhesives or the like to form the longitudinal element 12a. Alternatively, the individual longitudinal elements 28a, 32a could be by means of at least one

Connecting means to be connected to one another to form the longitudinal element 12a. The wire rope 34a formed from the individual longitudinal elements 28a, 32a has a lay. The longitudinal element 12a shown in Fig. 1 has a right turn. Alternatively, the wire rope 34a could have a left turn. The wire rope 34a formed from the individual longitudinal elements 28a, 32a has one

Impact angle 36a. The impact angle 36a is spanned by a single longitudinal element 28a, 32a and the longitudinal direction 14a of the longitudinal element 12a. The impact angle 36a is less than 25 °. In that shown in Fig. 1

Impact angle 36a crosses the thread pitch angle 70a. An intersection angle 88a between the runout of the longitudinal element 12a and a thread flank 82a, 84a of the external thread 16a is between 65 ° and 115 °. In the exemplary embodiment shown, the crossing angle 88a is approximately 80 °. The

Thread pitch of the external thread 16a and a pitch of the lay of a stranded single longitudinal element 28a, 32a have different

Slope directions on. This can advantageously prevent the individual longitudinal elements 28a, 32a of the stranded into a wire rope 34a

Unscrew the longitudinal elements 12a when screwing and / or tightening the screw element 60a. Alternatively, the thread pitch of the external thread 16a and the pitch of the lay could be stranded

Individual longitudinal elements 28a, 32a have the same direction of inclination.

FIG. 3 shows a section through the longitudinal element 12a of the fastening and / or connecting device 10a along a sectional plane A perpendicular to the longitudinal direction 14a.

educated. The second stranding layer 90a has 12 individual longitudinal elements 28a, 32a. The second stranding layer 90a is designed as an inner stranding layer. The third stranding layer 40a has 18 individual longitudinal elements 28a, 32a. The third stranding layer 40a is designed as an inner stranding layer.

The stranding layers 38a, 40a, 90a, 92a are adjacent to one another. The individual longitudinal elements 28a, 32a of a stranded layer 38a, 40a, 90a lying outside in a radial direction of the longitudinal element 12a outside of the individual longitudinal elements 28a, 32a of an adjacent stranding layer 40a, 90a, 92a are spirally wound around the adjacent stranding layer 40a, 90a, 92a. The longitudinal element 12a is a four-layer

(1 + 6 + 12 + 18 + 24) spiral wire rope formed. In each case two of the stranding layers 38a, 40a, 90a, 92a of the longitudinal element 12a are twisted crosswise to compensate for torque. In the exemplary embodiment shown, the innermost stranded layer 92a has a left turn. In the exemplary embodiment shown, the second stranding layer 90a has a right turn. In the shown

In the exemplary embodiment, the third strand layer 40a has a left turn. In the exemplary embodiment shown, the outer fourth stranded layer 38a has a right turn. When a tensile force is exerted on the longitudinal element 12a, opposite torques advantageously act on adjacent stranding layers 38a, 40a, 90a, 92a. A mutual "interlocking" of the

Individual longitudinal elements 28a, 32a of the respective stranding layers 38a, 40a, 90a, 92a advantageously prevent the longitudinal element 12a from being constricted, as a result of which, in particular, a change in the outer diameter 30a of the longitudinal element 12a can be kept small under tensile load. The individual longitudinal elements 28a, 32a of the stranding layers 38a, 40a, 90a, 92a have at least essentially identical tensile strengths.

Individual longitudinal elements 28a ’, 32a’ of the outer stranding layer 38a with the partially polygonal cross section 46a are at least partially adapted to a shape of the individual longitudinal elements 28a, 32a of the adjacent inner stranding layer 40a.

FIG. 4 shows a further section through the longitudinal element 12a of the fastening and / or connecting device 10a along a sectional plane B perpendicular to the longitudinal direction 14a. The sectional plane B is indicated in FIG. 2. Fig. 3 shows a section through the thread tip 78a of the external thread 16a.
