[0070] First anchor plate 3 is spaced apart from second anchor plate 7. The boreholes of anchor plates 3 and 7 are disposed along the edges of anchor plates 3 and 7.

[0071] FIG. 2 shows anchoring device 1 from FIG. 1 with another component. Anchoring device 1 additionally has a pocket formwork 15. Pocket formwork 15 is inserted in central recess 4 of first anchor plate 3. Flanges or folded edges of pocket formwork 15 rest flat on the topside of first anchor plate 3. Pocket formwork 15 has openings, anchor rods 2 penetrating the openings. Nuts 5 are now attached to anchor rods 2 on the flange topside.

[0072] Pocket formwork 15 serves to produce a foundation recess, which is called a pocket (German: K{hacek over (o)}cher) in professional terminology, in a concrete foundation, as described in more detail below.

[0073] FIG. 3 shows an anchoring device 1 with a pocket formwork 15 from FIG. 2 encased in a concrete foundation 21.

[0074] First, anchoring device 1 is encased in concrete foundation 21, first anchor plate 3 being placed far enough above concrete foundation 21 for nuts 6 of first anchor plate 3, which are disposed on the underside of first anchor plate 3, to be disposed far enough above concrete foundation 21 to allow first anchor plate 3 to be adjusted upward (positive Z-direction in the drawing plane) and downward (negative Z-direction in the drawing plane) along the length of anchor rods 2 by turning nuts 6. Nuts 5 are removed prior to leveling. Nuts 5 will later be screwed back onto anchor rods 2 when mounting the column for attaching column base 23 by means of centering disks 26.

[0075] Subsequently, first anchor plate 3 is leveled or aligned by turning nuts 6 of first anchor plate 3, which are disposed on the anchor plate underside. For mounting column 22, all first anchor plates 3 located in the construction section are adjusted to the constructively required height by turning nuts 6, which are disposed on the anchor plate underside.

[0076] For producing pocket 25 in concrete foundation 21, pocket formwork 15 is introduced into central recess 4 of first anchor plate 3. Pocket formwork 15 is removed again after pocket 25 has been produced in concrete foundation 21.

[0077] FIG. 4 shows a section A-A from FIG. 3. Second anchor plate 7 and anchor rods 2 are encased in concrete foundation 21 below nuts 6 of first anchor plate 3, which are disposed on the anchor plate underside. The surface of concrete foundation 21 is spaced apart from nuts 6 (distance 17).

[0078] FIG. 5 shows encased anchoring device 1 from FIG. 3, pocket formwork 15 having been removed again after the concreting process of concrete foundation 21 and nuts 5 again resting on the plate topside. However, nuts 5 are not needed at this stage of the method.

[0079] FIG. 6 is a schematic view of an anchorage 20. Anchorage 20 comprises a concrete foundation 21, a column 22, in particular a steel column or a partially concrete-encased column, which has a column base or a column base plate 23, and anchoring device 1, as described above.

[0080] When placing column base 23 of column 22 on first anchor plate 3, a shear key 24 is disposed on the column base underside. Shear key 24 protrudes into pocket 25 of foundation 21. Projecting anchor rods 2 penetrate boreholes of column base 23.

[0081] A centering disk 26 is disposed on each anchor rod 2 on the column base topside. Subsequently, nuts 5, which are disposed on the anchor plate topside and which are mounted on anchor rods 2 in a rotatable manner, are tightened until they come into contact with the centering disks.

[0082] FIG. 7 shows anchorage 20 from FIG. 6 with additions. A cavity disposed between concrete foundation 21 and column base 23 in the form of a pocket 25 (cf. FIG. 8) between the flange underside of column base 23 and the bottom of the foundation recess is mortared with non-shrink mortar 28 or is alternatively concreted.

[0083] FIG. 8 shows a section B-B through the anchorage of FIG. 7.

[0084] A column base 23 of column 22 rests on first anchor plate 3, a shear key 24 being disposed on the column base underside. Anchor rods 2 are guided through openings of column base 23. Furthermore, centering disks 26 are disposed on the column base topside. Centering disks 26 themselves are attached to anchor rods 2 by means of nuts 5.

[0085] Shear key 24 has an I-section.

[0086] Second anchor plate 7 and anchor rods 2 are encased in concrete foundation 21 below nuts 6 of first anchor plate 3, which are disposed on the anchor plate underside, a space existing between the surface of concrete foundation 21 and nuts 6.

[0087] As mentioned above, pocket 25, which is disposed between concrete foundation 21 and column base 23, is mortared or concreted.

[0088] Nuts 6 of first anchor plate 3, which are disposed on the anchor plate underside, and first anchor plate 3 are disposed in pocket 25.

[0089] FIG. 9 shows another embodiment of anchoring device 1. Anchoring device 1 comprises four anchor rods 2 and a first anchor plate 3. First anchor plate 1 can be understood as an anchor template. First anchor plate 3 has a central recess 4 and boreholes. Each anchor rod 2 is guided through one borehole. One nut 6 is screwed onto each anchor rod 2. Nuts 6 serve as rests for first anchor plate 3, nuts 6 being disposed on the anchor plate underside. Furthermore, nuts 5 are provided. In FIG. 9, nut 6 is covered by first anchor plate 3. Nuts 5 serve to fix or position first anchor plate 3, nuts 5 being disposed on the anchor plate topside.

[0090] Anchoring device 1 comprises other anchor plates 7, 8, 9 and 10. The other anchor plates can be understood as bracings or bracing plates. Each of anchor plates 7, 8, 9 and 10 has a borehole. Each anchor rod 2 is guided through one of the boreholes. Two nuts 11, 12 are screwed onto each anchor rod 2. Nuts 12 serve as rests for anchor plates 7, 8, 9 and 10, nuts 12 being disposed on the anchor plate underside. Nuts 11 serve to fix or position anchor plates 7, 8, 9 and 10, nuts 11 being disposed on the anchor plate topside.

[0091] First anchor plate 3 is spaced apart from other anchor plates 7, 8, 9 and 10. The boreholes of anchor plates 3, 7, 8, 9 and 10 are disposed along the edges of anchor plates 3, 7, 8, 9 and 10.

[0092] Anchoring device 1 of FIG. 9 shows another option for configuring the anchoring device.

[0093] As another alternative, at least two other anchor plates 7, 8 can be used instead of the four anchor plates 7, 8, 9 and 10 shown in FIG. 9.

[0094] In this case, first other anchor plate 7 can replace anchor plates 7 and 8 from FIG. 9, and second other anchor plate 8 can replace anchor plates 9 and 10 from FIG. 9. Furthermore, first other anchor plate 7 can replace anchor plates 7 and 9 from FIG. 9, and second other anchor plate 8 can replace anchor plates 8 and 10 from FIG. 9.

[0095] The other two anchor plates 7 and 8 then have at least one opening, one of the anchor rods being guided through each of the openings, and two other nuts per anchor rod fixing the two other anchor plates 7 and 8 on the anchor plate topside and on the anchor plate underside.

[0096] This shows another option for configuring the anchoring device.

[0097] As another alternative, at least three other anchor plates 7, 8, 9 can be used instead of the four anchor plates 7, 8, 9 and 10 shown in FIG. 9. In this case, one of the anchor plates can have two openings, an anchor rod 2 being guided through each opening. The second and third anchor plates can each have one opening with one anchor rod 2 guided therein. Thus, a plurality of possible combinations with three bracing plates and four anchor rods can be realized.

[0098] Thus, different options of how to divide the second anchor plate into one, two, three or more bracing plates arise depending on the need and the number of anchor rods. Individual bracing plates can have one, two or more openings or bores for accommodating one, two or more anchor rods depending on how the second anchor plate is divided, which means there are various possible combinations and arrangements between the number of the individual bracing plates and the number of openings for accommodating anchor rods in the respective bracing plates. Also, the outer contours of the individual bracing plates can be formed according to all known shapes; the shaping of the outer contour of each of the individual bracing plates can be selected individually, allowing a uniform shaping of outer contours or any possible mixture of outer contours to be obtained.
