Anchoring device, anchoring with anchoring device and method of manufacturing the anchoring

The invention relates to an anchoring device. The invention further relates to an anchoring — with an anchoring device. The invention furthermore relates to a method of manufacturing the anchoring.

A number of anchoring devices are known from the prior art. For example, from EP 2 411 586 A1 there is known a system for connecting metal components made of steel, which comprises two plates that are equipped with slots, and screw pins that are guided through the slots and connect the plates to each other.

An anchor in the construction industry is a component part for the tension-proof connection (anchoring) of component parts. Anchors are mainly made of steel, but can also be — manufactured from wood, steel or prestressed concrete or other tension-proof materials.

The anchoring devices made of steel can consist of yokes and main bearing irons and can be welded together to form a cage. Depending on the application, various materials and quantities can be used.

US 5533 835 A discloses an anchoring device according to the preamble of Claim 1.

A disadvantage of the prior art is that the known anchoring devices have to be welded together, which is why it is no longer possible to adapt the anchoring devices at a later point in time.

The present invention is therefore based on the problem of overcoming the disadvantages known from the prior art.

This problem is solved by an anchoring device with the features of claim 1, by an anchoring comprising an anchoring device with the features of claim 7 and by a method of manufacturing the anchoring with the features of claim 12.

The anchoring device according to the invention comprises at least two, preferably three and particularly preferably four anchor rods and a first anchor plate, wherein the first anchor plate has a centrally arranged recess and apertures, wherein each anchor rod is respectively guided through an aperture and in each case one nut per anchor rod is mounted on the first anchor plate, at the underside of the anchor plate, wherein the anchoring device further comprises further anchor plates corresponding to the number of anchor rods, wherein each of the further anchor plates has an aperture, wherein one of the anchor rods is guided through each of the apertures and in each case two further nuts per anchor rod, one of the two further nuts at the upper side of the anchor plate and the other of the two further nuts at the underside of the anchor plate, fix the further anchor plates.

According to the invention, the anchoring device comprises, alongside the first anchor plate, further anchor plates, wherein each of the further anchor plates has at least one aperture, wherein one of the anchor rods is guided through each of the apertures and in each case two further nuts per anchor rod, at the upper side of the anchor plate and at the underside of the anchor plate, fix the at least two anchor plates.

Therefore, the anchoring device can comprise two further anchor plates for two anchor rods, two or three further anchor plates for three anchor rods, two, three or four further anchor plates for four anchor rods, and so on.

The first anchor plate can be understood to be an anchoring template.

An opening can be understood to be a borehole or a drilled hole. The second or further anchor plates can be understood to be a back anchoring, a back anchoring means or a — back anchoring plate.

The shaping of the outer contour of the first anchor plate and/or the further anchor plates can, in principle, be formed according to the outer contour of all known geometric shapes.

The choice of outer contour shape depends on the outer contour of the support. For example, a circular outer contour is used in the case of a round tube support if a support base plate to be connected also has such an outer contour and the anchor rods are arranged along a circular line and parallel to each other between the back anchoring plate and the support base plate. — The shaping of the inner contour of the aperture or recess in the first anchor plate is not subject to any strict specifications. It can have any known geometric shape, with a rectangular, square or circular contour being particularly preferred. This also applies to the shaping of the bucket formwork, which is inserted into the recess and removed again later after casting. The shaping of the bucket and, associated with this, the shape of the body of the bucket formwork, can be cuboid, cube-shaped, pyramidal, cylindrical, truncated cone- shaped or hemispherical. Preferably, when choosing the shaping of the recess contour and the cross-sectional contour of the bucket formwork, there should be a form-fitting connection when the bucket formwork is introduced into the recess.

The anchor rods can be configured as anchor bolts or anchor supports, for example in the form of anchor plate spacer elements. The end faces of the spacer element preferably each have two shorter anchor rods, which accommodate the nuts and the anchor plates.

The number of anchor rods can be freely chosen. For reasons of stability when assembling the support, at least three anchor rods are preferably used, as a support base can thus be placed and aligned on a sufficiently stable first anchor plate. For reasons of stability when assembling the support, four anchor rods are preferably used. It is particularly preferable to use more than four anchor rods. This results in above-average stability.

The anchoring device is only screwed together and not welded during production. This allows the anchoring device to be adjusted at a later point in time. Furthermore, the use of high-strength anchor rods with a grade of 8.8 is also envisaged, with 10.9 and 12.9 and all other material grades also being possible. As a result, it is possible to transmit large tensile — forces with a relatively small nominal diameter of the anchor rods. The anchoring device can be understood as an anchor cage or reinforcement cage. Anchor rods can also be understood to be anchor bolts or threaded rods. The anchor rods have, at least in part, one or more threads. Accordingly, all of the nuts used have an inner thread which meshes with the thread on the anchor rods.

When installing the anchoring device in a concrete foundation, the first anchor plate, particularly in the form of an anchoring template, can be set with a recess with a diameter- dependent spacing to the upper edge of a foundation. This ensures that the nuts on the underside of the first anchor plate can still be rotated.

Preferably, the first anchor plate is spaced apart from the second anchor plate and/or from the further anchor plates. This gives the anchoring device sufficient stability. The spacing must be selected in such a way that, on the one hand, it meets the structural requirements and that, on the other hand, there is a sufficiently large concrete cover between a bucket to be produced and the back anchoring. A spacing between the first anchor plate and the second and/or further anchor plates can be 20 cm or more, for example.

Preferably, each of the further anchor plates has at least one aperture. — More preferably, the apertures are arranged on the edge of the anchor plates. Thus, the anchor rods can be easily guided through the anchor plate.

Furthermore, in the case of the anchoring device according to the invention, a bucket formwork is removably inserted into the central recess of the first anchor plate, wherein flanges, or lips, of the bucket formwork rest, on the anchor plate upper side, planarly on the first anchor plate. The bucket formwork can thus be vertically supported in a simple manner. The bucket formwork is used to produce a bucket. A bucket can be understood to be a cavity, a clearance, a recess or a hollow in a foundation.

Preferably, the bucket formwork also has apertures, wherein the anchor rods penetrate the apertures. As a result, the bucket formwork is connected to the first anchor plate in a simple manner.

The anchoring device furthermore preferably comprises nuts arranged on the upper side of the anchor plate or centering discs and nuts arranged on the upper side of the support base plate or upper side of the flange, with the nuts being rotatably mounted on the anchor rods. Thus, the first anchor plate or the bucket formwork can be fixed.

The anchoring according to the invention comprises a concrete foundation, a support, in particular steel supports or aerated concrete supports, and an anchoring device as described above, wherein a support base of the support is vertically supported on the first anchor plate, wherein a shear cleat is arranged on the underside of the support base, and — the anchor rods are guided through apertures in the support base, and wherein centering discs are arranged on the upper side of the support base and the centering discs are attached to the anchor rods by means of nuts.

To install supports, the first anchor plates (templates) of all anchoring devices located in the — same construction section are set to the same height by turning the nuts located on the underside of the first anchor plates. For this purpose, the nuts arranged on the upper side of the anchor plate must be removed beforehand. This makes it possible to achieve an installing level that allows all steel supports to be installed at exactly the same height (z- direction) without the need to install lining plates. After levelling, the screws are screwed — back onto the anchor rods to secure the centering discs to the support base plate.

To enable the supports to be adjusted in an x and y direction, large apertures or large boreholes are arranged in the support base plates of the supports. The bore diameter, for example, can be freely selected in design-engineering terms. The bore diameter can be a multiple of, for example three times, the nominal diameter of the anchor rod. As a result, it is possible to obtain a tolerance range for displacing the support of plus/minus a simple nominal diameter of the anchor rod, in the x and y directions.

The large boreholes can be covered with the centering discs. A centering disc can be understood to be an eccentric disc. Preferably, the size of the discs is such that, in any position of the anchor rod relative to the middle of the aperture or centre of the bore, the aperture or borehole is completely covered, in addition to an excess length selected 5 according to structural requirements. The shaping of the outer contour of the centering disc or excentric disc can likewise be configured in accordance with the outer contour of all known geometric shapes. Circular and/or square outer contours are preferably cited here for the centering discs. — The discs are not welded to the anchor plate. As a result, there is also no need for subsequent repair of the corrosion protection.

As the anchor rods cannot transmit forces orthogonally to the anchor rod due to the large boreholes, an additional structural element is required. A shear cleat is used. The shear cleat has a cross-section that meets the structural requirements. In principle, all known cross-section profiles, as well as individually manufactured or welded cross-section profiles, are possible for the shear cleat. The shear cleat is welded onto the underside of the support base. As the support base plate rests or is placed directly on the first anchor plate, an aperture is required in the first anchor plate to allow the shear cleat to pass through.

When manufacturing the foundation, it is necessary to produce the bucket into which the shear cleat reaches and via which the loads can be transmitted orthogonally to the anchor rod after the support has been installed and the bucket has been cast.

Preferably, the shear cleat is welded onto the support base. This makes it easy to absorb shear forces. The shear cleat can be designed as an I-profile. Other commercially available profile cross-sections that meet the structural requirements can also be used. In principle, all known cross-section profiles, as well as individually manufactured or welded cross- section profiles, are possible for the shear cleat.

Preferably, the additional anchor plates or the second anchor plate and the anchor rods are concreted into the concrete foundation, wherein a spacing relative to the nuts of the first anchor plate, which are on the underside of the anchor plate, is present on the upper side of the concrete foundation. Here, there must be sufficient spacing underneath the nuts, relative to the upper side of the concrete foundation, for the nuts to be able to be turned for the purpose of levelling the upper anchor plate. As a result, a sufficiently structural connection is achieved between the foundation and the anchoring device.

More preferably, a bucket is arranged between the concrete foundation and the support base, with the nuts on the underside of the anchor plate and the first anchor plate and the shear cleat being arranged or inserted in the bucket. This allows the first anchor plate to be leveled out by turning the nuts on the underside of the anchor plate to accommodate the support. For levelling, the nuts of the first anchor plate which are arranged on the upper side of the anchor plate must be removed previously, as mentioned above. The bucket is preferably mortared or concreted. This is done after the steel construction or steel support has been aligned.

The method according to the invention for producing a load-bearing anchoring comprises the following steps: - embedding an anchoring device, in particular, as described above, into a concrete foundation, wherein the anchoring device comprises at least two anchor rods and a first anchor plate, wherein the first anchor plate has a centrally arranged recess and apertures, wherein each anchor rod is respectively guided through an aperture and in each case one nut per anchor rod is mounted on the first anchor plate at the underside of the anchor plate, wherein the anchoring device further comprises further anchor plates corresponding to the number of anchor rods, wherein each of the further anchor plates has an aperture, wherein one of the anchor rods is guided through each of the apertures and in each case two further nuts per anchor rod, one of the two further nuts at the upper side of the anchor plate and the other of the two further nuts at the underside of the anchor plate, fix the further anchor plates, wherein the further anchor plates or the second anchor plate and the anchor rods are embedded in the concrete foundation, and wherein, on the upper side of the concrete foundation, there is a spacing from the nuts of the first anchor plate which are on the underside of the anchor plate, - levelling or aligning the first anchor plate by rotating the nuts of the first anchor plate, which are on the underside of the anchor plate, - placing a support base of a support onto the first anchor plate, wherein there is arranged on the underside of the support base a shear cleat, which protrudes into a bucket of the foundation and wherein the projecting anchor rods penetrate through apertures of the support base, - arranging centering discs on the upper side of the support base, and - tightening nuts on the upper side of the centering discs to fix the centering discs.

The nuts of the first anchor plate, which are arranged on the upper side of the anchor plate, are removed prior to levelling or aligning the first anchor plate.

In the method according to the invention, to produce the bucket in the concrete foundation, a bucket formwork is introduced into the central recess of the first anchor plate, wherein the bucket formwork is removed again once the bucket has been produced in the concrete foundation. The bucket formwork can therefore be reused.

The method particularly preferably also comprises the following step: - filling up the bucket in the region between the underside of the support base and the upper side of the foundation with non-shrinking mortar or concrete. — The anchor bars protrude sufficiently at the upper side of the foundation. When the steel support is placed onto the foundation, the shear cleat dips into the bucket which is of sufficiently large size that there is a clearance between the shear cleat and the inner surface of the recess when the steel support is placed on in the end position.

If the steel support is aligned, the anchor bolts are fixed with the centering discs on the flange on the upper side of the support base and the foundation recess between the shear cleat, the flange underside and the foundation recess is filled with non-shrinking mortar/concrete.

The entire assembly is performed without reworking the foundation, the flange (support base plate) and the anchors.

The employment of an expanded polystyrene brick to create a corresponding recess in a foundation is known from the prior art.

In the present case, when installing the anchoring device, it is ensured through a formwork device, which is screwed together with the anchor rods, that a bucket is created in the required size and at exactly the correct location when concreting the foundation. — This formwork device preferably consists of a material which can effectively prevent the adhesion of concrete or mortar using a formwork release agent. The material is preferably resistant to weathering.

Particularly preferably, the formwork device is reusable. This is advantageous particularly in — the case of standardised anchoring devices, since the formwork device can be acquired from the same supplier/manufacturer who also supplies the anchoring device.

In addition, this type of bucket formwork eliminates the need for the costly cleaning of the bucket that is necessary when using expanded polystyrene bricks, accompanying the disposal of the polystyrene residues.

After casting the bucket, it is possible to obtain a support anchoring which permits a structurally optimal load application of all arising forces (x, y, z) into the foundation.

In a further embodiment, it is possible to obtain a gripping at the support base point. This is produced through a structural necessary arrangement of the anchor rods with regard to the support cross-section.

High-strength anchor rods in grades 8.8, 10.9 or 12.9 are preferably used, with all other material grades also being able to be used in accordance with the applicable norms. The number, diameter and anchoring length of these must be selected according to the structural reguirements. Furthermore, the dimensioning of the back anchoring (second anchor plate) must be taken into account, with the back anchoring length, alongside the dimensioning, also being dependent on the concrete reinforcement as well as the concrete grade.

A dimensioning of the anchoring device is based on the design-engineering as well as the structural requirements.

The invention will be explained below in greater detail, with reference to the enclosed drawings. In the drawings:

Figure 1 shows an anchoring device 1. The anchoring device 1 comprises four anchor rods 2 and a first anchor plate 3. The first anchor plate 1 can be understood to be an anchoring template. The first anchor plate 3 has a centrally arranged recess 4 and drilled holes. Each anchor rod 2 is respectively guided through one of the drilled holes. In each case a nut 6 is screwed onto the anchor bars 2. The nuts 6 serve as vertical supports for the first anchor plate 3, with the nuts 6 being arranged on the underside of the anchor plate. In Figure 1, the nut 6 is concealed by the first anchor plate 3. However, they are shown in Figure 4, for example. Furthermore, nuts 5 are provided. The nuts 5 serve to fix or position the first anchor plate 3, with the nuts 5 being arranged on the upper side of the anchor plate.

The anchoring device 1 further comprises a second anchor plate 7. The second anchor — plates can be understood to be a back anchoring or a back anchoring plate. The second anchor plate 7 has drilled holes. Each anchor rod 2 is respectively guided through one of the drilled holes. In each case, two nuts 11, 12 are screwed onto the anchor rod 2. The nuts 12 serve as vertical supports for the second anchor plate 7, with the nuts 12 being arranged on the underside of the anchor plate. The nuts 11 serve to fix or position the — second anchor plate 7, with the nuts 11 being arranged on the upper side of the anchor plate.

The first anchor plate 3 is spaced apart from the second anchor plate 7. The drilled holes of the anchor plate 3, 7 are arranged at the edge along the anchor plate 3, 7.

Figure 2 shows the anchoring device 1 from Figure 1 with an additional component part.

The anchoring device additionally has a bucket formwork 15. The bucket formwork 15 is inserted into the central recess 4 of the first anchor plate 3. Flanges, or lips, of the bucket formwork 15 rest planarly on the first anchor plate 3, on the anchor plate upper side. The bucket formwork 15 has apertures, wherein the anchor rods 2 penetrate the apertures. The nuts 5 are now secured to the anchor rods 2, on the upper side of the flange.

The bucket formwork 15 serves to produce a foundation recess, which is called a bucket in technical terminology, in a concrete foundation, as will be described later.

Figure 3 shows an anchoring device 1, which is embedded into a concrete foundation 21, with a bucket formwork 15 from Figure 2.

Firstly, the anchoring device 1 is concreted into the concrete foundation 21, with the first anchor plate 3 being inserted so far above the concrete foundation 21 that the nuts 6 arranged on the underside of the first anchor plate 3 are arranged so far above the concrete foundation 21 that the first anchor plate 3 can be moved along the longitudinal extension of the anchor rods 2, upwards (in the positive Z direction in the plane of the sheet) and downwards (in the negative Z direction in the plane of the sheet), by turning the nuts 6. The nuts 5 are removed before levelling. The nuts 5 are screwed back onto the anchor rods 2 later during support installation to secure the support base 23 using centering discs 26.

Levelling or aligning the first anchor plate 3 is then performed by rotating the nuts 6 of the first anchor plate 3, which are on the underside of the anchor plate. To install the support 22, all first anchor plates 3 in the construction section are adjusted to the structurally required height by turning the nuts 6 on the underside of the anchor plate.

To produce the bucket 25 in the concrete foundation 21, the bucket formwork 15 is introduced into the central recess 4 of the first anchor plate 3. The bucket formwork 15 is removed again after the bucket 25 is produced in the concrete foundation 21. — Figure 4 shows a section A-A from Figure 3. The second anchor plate 7 and the anchor rods 2 are embedded in the concrete foundation 21 underneath the nuts 6 of the first anchor plate 3 which are on the underside of the anchor plate. The surface of the concrete foundation 21 is spaced apart from the nuts 6 (spacing 17). — Figure 5 shows the concreted-in anchoring device 1 from Figure 3, with the bucket formwork 15 having been removed again after the concreting process of the concrete foundation 21 and with the nuts 5 resting on the upper side of the plate. However, the nuts 5 are not required at this stage of the method. — Figure 6 shows a schematic view of an anchoring 20. The anchoring 20 comprises a concrete foundation 21, a support 22, in particular a steel support or aerated concrete support, with a support base or support base plate 23 and the anchoring device 1, as described above. — When the support base 23 of the support 22 is placed onto the first anchor plate 3, a shear cleat 24 is arranged on the underside of the support base. The shear cleat 24 protrudes into the bucket 25 of the foundation 21. The projecting anchor rods 2 penetrate drilled holes of the support base 23.

On the upper side of the support base, one centering disc 26 in each case is arranged on the anchor rods 2. The nuts 5 on the upper side of the anchor plate, which are rotatably mounted on the anchor rods 2, are then tightened until they contact the centering discs.

Figure 7 shows the anchoring 20 from Figure 6, with additions. A cavity in the form of a bucket 25 (cf. Figure 8), which is arranged between the concrete foundation 21 and the support base 23, between the flange underside of the support base 23 and the floor of the foundation recess, is mortared by means of non-shrinking mortar 28, or alternatively concreted.

Figure 8 shows a section B-B through the anchoring from Figure 7.

A support base 23 of the support 22 rests on the first anchor plate 3, with a shear cleat 24 being arranged on the underside of the support base. The anchor rods 2 are guided — through apertures in the support base 23. Furthermore, centering discs 26 are arranged on the upper side of the support base. The centering discs 26 themselves are secured to the anchor rods 2 by means of nuts 5.

The shear cleat 24 has an |-profile.

The second anchor plate 7 and the anchor rods 2 are embedded in the concrete foundation 21 underneath the nuts 6 of the first anchor plate 3 which are on the underside of the anchor plate, wherein a clearance exists between the surface of the concrete foundation 21 and the nuts 6.

As mentioned above, the bucket 25 arranged between the concrete foundation 21 and the support base 23 is mortared or concreted.

The nuts 6 of the first anchor plate 3, which are on the underside of the anchor plate, and the first anchor plate 3 are arranged in the bucket 25.

Figure 9 shows an additional embodiment of the anchoring device 1. The anchoring device 1 comprises four anchor rods 2 and a first anchor plate 3. The first anchor plate 1 can be understood to be an anchoring template. The first anchor plate 3 has a centrally arranged recess 4 and drilled holes. Each anchor rod 2 is guided through one drilled hole in each case. One nut 6 in each case is screwed onto an anchor rod 2. The nuts 6 serve as vertical supports for the first anchor plate 3, with the nuts 6 being arranged on the underside of the anchor plate. Furthermore, nuts 5 are provided. In Figure 9, the nut 6 is concealed by the first anchor plate 3. The nuts 5 serve to fix or position the first anchor plate 3, with the nuts being arranged on the upper side of the anchor plate.

The anchoring device 1 comprises further anchor plates 7, 8, 9, 10. The additional anchor 5 plates can be understood to mean a back anchoring or back anchoring plates. Each of the anchor plates 7, 8, 9, 10 has a drilled hole. Each anchor rod 2 is respectively guided through one of the drilled holes. In each case, two nuts 11, 12 are screwed onto an anchor rod 2. The nuts 12 serve as vertical supports for the anchor plates 7, 8, 9, 10, with the nuts 12 being arranged on the underside of the anchor plate. The nuts 11 serve to fix or position — the anchor plates 7, 8, 9, 10, with the nuts 11 being arranged on the upper side of the anchor plate.

The first anchor plate 3 is spaced apart from the further anchor plates 7, 8, 9, 10. The drilled holes of the anchor plates 3, 7, 8, 9, 10 are arranged at the edge along the anchor plates 3, 7, 8, 9, 10.

With the anchoring device 1 according to Figure 9, an additional possibility of configuring the anchoring device is shown.

As a further alternative, but not inventively, it is also possible to use at least two additional anchor plates 7, 8 instead of the four anchor plates 7, 8, 9, 10 shown in Figure 9.

In this case, the first additional anchor plate 7 can replace the anchor plates 7, 8 from

Figure 9 and the second additional anchor plate 8 can replace the anchor plates 9, 10 from — Figure 9. In addition, the first additional anchor plate 7 can replace the anchor plates 7, 9 from Figure 9 and the second additional anchor plate 8 can replace the anchor plates 8, 10 from Figure 9.

The additional two anchor plates 7, 8, then have at least one aperture, wherein one of the anchor rods is guided through each of the apertures and in each case two further nuts per anchor rod, at the upper side of the anchor plate and at the underside of the anchor plate, fix the two anchor plates 7, 8.

As a result of this, an additional possibility of configuring the anchoring device is shown.

As a further alternative, but not inventively, it is also possible to use at least three additional anchor plates 7, 8, 9 instead of the four anchor plates 7, 8, 9, 10 shown in Figure 9. One of the anchor plates can have two apertures, with one anchor rod 2 being guided through each aperture. The second and third anchor plates can each have an aperture with one anchor rod 2 guided in it in each case. Thus, a number of possible combinations can be realised with three back anchoring plates and four anchor rods.

Thus, depending on the requirements and number of anchor rods, there emerge different possibilities for dividing the second anchor plate into one, two, three or more back anchoring plates. Depending on the circumstances of the division of the second anchor plate, individual back anchoring plates can have one, two or more apertures or boreholes for receiving one, two or more anchor rods, as a result of which there exist different — possible combinations and arrangements between the number of individual back anchoring plates and the number of apertures for receiving anchor rods in the respective back anchoring plates. The outer contours of the individual back anchoring plates can also be formed in accordance with all known shapes, whereby the shaping of the outer contour of the individual back anchoring plates can be selected differently in each case, as a result of — which a uniform shaping of outer contours or any desired mixture of outer contours can be achieved.
