Description

[Technical field]

[0001] The present invention relates to an anchoring device. Further, the present invention relates to a fastener including the anchoring device. Also, the present invention relates to a method of manufacturing the fastener. [Background technology]

[0002] Several anchoring devices are known from the prior art. In the construction industry, anchors are components for tension-resistant connections (fixtures) of components. Anchors are mainly made of steel, but can also be manufactured from wood, reinforced concrete, prestressed concrete or other tension-resistant materials. Steel anchoring devices consist of reinforcing bars and main bars, which can be welded together to form a cage. Depending on the use, different materials and quantities can be used. Summary of the Invention [Problem to be solved by the invention]

[0003] The prior art is disadvantageous in that the known anchoring devices must be welded, which means that the anchoring devices cannot be subsequently adjusted.

[0004] It is therefore an object of the present invention to overcome the drawbacks known from the prior art. [Means for solving the problem]

[0005] This object is achieved by an anchoring device having the features of claim 1, by a fixing tool comprising an anchoring device having the features of claim 8 and by a method for manufacturing an anchoring device having the features of claim 13.

[0006] The anchoring device according to the invention comprises at least two, preferably three and particularly preferably four anchor rods and a first anchor plate, which preferably has a central recess and openings, in particular for accommodating a pocket formwork, each anchor rod being guided through one opening and one nut per anchor rod being attached to the underside of the first anchor plate, the anchoring device further comprising a second anchor plate and / or further anchor plates corresponding to the number of anchor rods.

[0007] The second anchor plate has openings, one of the anchor rods is guided through each opening, and two other nuts per anchor rod secure the second anchor plate to the upper side of the second anchor plate and to the lower side of the second anchor plate.

[0008] The other anchor plates corresponding to the number of anchor rods each have an opening, one of the anchor rods guided through each opening, and two nuts for each anchor rod that secure the other anchor plate to the upper side of the other anchor plate and the lower side of the other anchor plate.

[0009] Particularly preferably, the anchor device comprises, in addition to the first anchor plate, other anchor plates, each of which has at least one opening, one of the anchor rods being guided through each opening and, for each anchor rod, two other nuts for fixing at least two other anchor plates on the upper side of the other anchor plate and on the lower side of the other anchor plate.

[0010] Thus, the anchor device may have two other anchor plates if there are two anchor rods, two or three other anchor plates if there are three anchor rods, and three or four other anchor plates if there are four anchor rods.

[0011] The first anchor plate can be understood as an anchor template. The openings can be understood as holes or perforations. The second anchor plate and other anchor plates can be understood as bracings, bracing means, or bracing plates.

[0012] The recess may be understood as an opening. The recess extends through the first anchor plate. The central recess may be understood as a recess located in the center or approximately centering of the first anchor plate. Preferably, the recess is configured to accommodate a pocket formwork.

[0013] The shaping of the outer contour of the first anchor plate and / or the other anchor plates can be basically formed according to the outer contour of all known geometric shapes. The choice of the shape of the outer contour depends on the outer contour of the column. For example, a circular outer contour is used for a round tubular column, if the column base plate to be connected also has such an outer contour and the anchor rods are arranged parallel to each other along a circular line between the bracing plate and the column base plate.

[0014] The shape of the inner contour of the opening or recess of the first anchor plate is not subject to strict specifications. It can have any known geometric shape, with rectangular, square or circular contours being particularly preferred. The same applies to the moulding of the pocket formwork which is inserted into the recess and removed again after grout injection. The shape of the pocket and therefore of the pocket formwork body can be rectangular, cuboid, pyramidal, cylindrical, truncated conical or hemispherical. Preferably, the choice of the shape of the recess contour of the pocket formwork and the cross-sectional contour should result in a form-fit when the pocket formwork is inserted into the recess.

[0015] Basically, anchor plate spacer elements can also be used instead of at least two anchor rods. They can be shaped differently than the rods and still provide sufficient stability. The anchor rods can be configured, for example, as anchor bolts or as anchor supports in the form of anchor plate spacer elements. The end faces of the spacer elements preferably have two short anchor rods, which respectively accommodate a nut and an anchor plate.

[0016] The number of anchor rods can be freely selected. For reasons of stability when mounting the columns, it is preferred to use at least three anchor rods, since then the column base can be placed and aligned on a sufficiently stable first anchor plate. For reasons of stability when mounting the columns, it is preferred to use four anchor rods. Particularly preferably, more than four anchor rods are used. This results in a higher stability than usual.

[0017] During manufacture, the anchoring device is simply screwed on and not welded. This allows the anchoring device to be adjusted later. Furthermore, high-strength anchor rods of grade 8.8 can also be used, as well as 10.9 and 12.9, as well as all other material grades. In this way, high tensile forces can be transmitted with a relatively low nominal diameter of the anchor rod. The anchoring device can be understood as an anchor cage or reinforcing cage. The anchor rods can also be understood as anchor bolts or threaded rods. At least some of the anchor rods have one or more threads. All nuts used therefore have an internal thread that meshes with the threads of the anchor rods.

[0018] When installing the anchor device on a concrete foundation, the first anchor plate with a recess can be placed at a distance that depends on the diameter from the upper edge of the foundation, in particular in the manner of an anchor template, so that the nut on the underside of the first anchor plate can still be turned.

[0019] Preferably, the first anchor plate is arranged at a distance from the second and / or other anchor plates. This provides an anchoring device with sufficient stability. The distance will be selected so that on the one hand the static requirements are met and on the other hand there is a sufficiently large concrete thickness between the produced pocket and the bracing. The distance between the first anchor plate and the second and / or other anchor plates can be, for example, 20 cm or more.

[0020] Preferably, each of the other anchor plates has at least one opening.

[0021] More preferably, the opening is located at the edge of the anchor plate, which allows the anchor rod to easily pass through the anchor plate.

[0022] Particularly preferably, the pocket formwork is inserted into a central recess of the first anchor plate, flange or folding edge of the pocket formwork, which rests flat on the upper side of the first anchor plate. That is, the recess of the first anchor plate is configured to receive the pocket formwork. This allows the pocket formwork to be easily attached. The pocket formwork serves to produce a pocket. A pocket can be understood as a cavity, space, recess or cutout in the foundation.

[0023] Preferably, the pocket formwork also has openings through which the anchor rods pass, in this way the pocket formwork is connected to the first anchor plate in a simple manner.

[0024] Preferably, the anchoring device further comprises a nut arranged on the upper side of the anchor plate, or a centering disk and a nut arranged on the upper side of the base plate or on the flange, the nut being attached to the anchor rod in a rotatable manner, so that the first anchor plate and the pocket formwork can be fixed.

[0025] The fixing device according to the invention comprises a concrete foundation, a column, in particular a steel column or a column partially encased in concrete, and an anchoring device according to any one of the claims, wherein the column base of the column rests on a first anchor plate, a shear key is arranged on the underside of the column base, an anchor rod is guided through an opening in the column base, a centering disk is arranged on the upper side of the column base, and the centering disk is attached to the anchor rod by means of a nut.

[0026] For the installation of the columns, the first anchor plates (templates) of all anchor devices located in the same construction section are adjusted to the same height by turning the nuts located on the lower side of the first anchor plate. To do this, it is necessary to first remove the nuts located on the upper side of the anchor plate. In this way, an installation surface is obtained where all steel columns can be installed at exactly the same height (z-direction) without the need to install a filler plate. After leveling, the nuts are screwed back onto the anchor rods and the centering disks are fixed to the column base plates.

[0027] To allow adjustability of the column in the x- and y-directions, a large opening or large hole is arranged in the column base plate of the column. Structurally, the hole diameter can be chosen freely, for example. The inner diameter can be a multiple of, for example, 3 times, the nominal diameter of the anchor rod. This results in a tolerance of ±1 of the nominal diameter of the anchor rod for shifting the column in the x- and y-directions.

[0028] The large holes can be covered with a centering disk. A centering disk can be understood as an eccentric disk. Preferably, the centering disk is of such a size that the opening or hole and the overlap selected according to the static requirements are covered at any position of the anchor rod relative to the opening center or hole center. The shaping of the outer contour of the centering disk or eccentric disk can also be formed according to the outer contour of all known geometric shapes. Preferably, a circular and / or square outer contour is referred to here for the centering disk.

[0029] The centering disk is not welded to the anchor plate, so no subsequent repair of the anti-corrosive coating is required.

[0030] An additional component is required because the anchor rod cannot transmit forces due to the large hole perpendicular to the anchor rod. A shear key is used. The shear key has a cross section that meets the static requirements. The shear key can have essentially any known cross section and an individually manufactured or welded cross section. The shear key is welded to the underside of the column base. The column base plate rests or is placed directly on the first anchor plate, so the first anchor plate needs an opening to allow the shear key to pass through.

[0031] To manufacture the foundation, it is necessary to manufacture pockets into which the shear keys protrude and which can transfer the load perpendicularly to the anchor rods after the installation of the columns and the grouting of the pockets.

[0032] Preferably, the shear key is welded to the column base. Thus, the shear forces can be absorbed in a simple manner. The shear key can be of I-section. Other commercially available sectional structures that meet the static requirements can be used as well. The shear key can have essentially all known sections and sections that are manufactured or welded separately.

[0033] Preferably, the second anchor plate and the anchor rod are embedded in the concrete foundation, and there is a distance between the upper side of the concrete foundation and the nut placed under the first anchor plate. There needs to be a sufficient distance between the lower surface of the nut and the upper surface of the concrete foundation so that the nut can be turned to level the upper anchor plate. This provides a sufficient static connection between the foundation and the anchor device.

[0034] Furthermore, preferably, a pocket is disposed between the concrete foundation and the column base, a nut is disposed on the underside of the first anchor plate, and the first anchor plate and the shear key are disposed or inserted in the pocket. This allows the first anchor plate to be leveled by turning the nut disposed on the underside of the first anchor plate to accommodate the column. For leveling, the nut disposed on the upper side of the first anchor plate must be removed first. Preferably, the pocket is made of mortar or concrete. This is done after the alignment of the steel structure or steel column.

[0035] A method for producing a load-bearing fixture according to the invention comprises the steps of: embedding an anchoring device, in particular one according to any one of the claims, in a concrete foundation and embedding the second anchor plate and the anchor rod in the concrete foundation, providing a distance between the upper side of the concrete foundation and the nut arranged on the lower side of the first anchor plate; leveling or aligning the first anchor plate by rotating a nut disposed on the underside of the first anchor plate; placing a column on the first anchor plate, placing a shear key on the column below the first anchor plate, protruding the shear key into a pocket in the foundation, and passing the protruding anchor rod through an opening in the column; placing a centering disk on the upper side of the column base; and placing a clamping nut over the centering disc to secure the centering disc.

[0036] The nut located on the top side of the first anchor plate is removed before the first anchor plate is leveled or aligned.

[0037] Preferably, the pocket form is introduced into the central recess of the first anchor plate to create a pocket in the concrete foundation, and the pocket form is removed again after the pocket has been created in the concrete foundation, so that the pocket form can be reused.

[0038] Particularly preferably, the method comprises the steps of: The method further includes filling the pockets with non-shrink mortar or concrete in the area between the lower side of the column base and the upper side of the foundation.

[0039] The anchor bar protrudes far enough from the top surface of the foundation that when the steel column is placed on the foundation, the shear key fits into a pocket that is large enough that there is space between the shear key and the inner surface of the recess when the steel column is resting on the foundation in its terminal position.

[0040] Once the steel column is aligned, the anchor bolts are secured to the top of the column base with a flange by a centering disk, and the foundation recess between the shear key, underside of the flange and the foundation recess is filled with non-shrink mortar / concrete.

[0041] Therefore, the entire installation work is done without any reworking to the foundation, flanges (column base plate) and anchors.

[0042] It is known from the prior art to insert polystyrene blocks to form corresponding recesses in the foundation.

[0043] Here, formwork devices screwed to the anchor rods are used to install the anchoring devices in order to ensure that when the foundation is concretized, a pocket of the required size is created in exactly the right position.

[0044] Preferably, the formwork device is made of a material that can effectively prevent concrete or mortar from sticking using formwork oil. Preferably, the material is weather resistant.

[0045] Particularly preferably, the formwork equipment is reusable, which is particularly advantageous in connection with standardized anchoring devices, since the formwork equipment can be sourced from the same supplier / manufacturer who also supplies the anchoring devices.

[0046] Additionally, pocket forms of this type eliminate the need for the use of polystyrene blocks and the associated tedious cleaning associated with disposal of scrap polystyrene.

[0047] After grouting of the pockets, columnar anchorages are obtained that allow a statically ideal load introduction into the foundation for all generated forces (x, y, z).

[0048] In another embodiment, a clamp at the column foundation can be obtained, said clamp being produced by the statically required positioning of the anchor rods relative to the column cross section.

[0049] Preferably, high strength anchor rods of grades 8.8, 10.9 or 12.9 are used, all other material grades according to current standards can be used as well. Their number, diameter and fixing length should be selected according to the static requirements, taking into account the dimensions of the braces (second anchor plate), the brace length, dimensions depending on the concrete rebar, concrete grade.

[0050] The dimensions of the anchoring device depend on both structural and static requirements. [Brief description of the drawings]

[0052] The present invention will now be described in more detail with reference to the drawings.

[0053] FIG. 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 as an anchor template. The first anchor plate 3 has a central recess 4 and boreholes. Each anchor rod 2 is guided through one of the boreholes. One nut 6 is screwed into each anchor rod 2. The nuts 6 serve as a seat for the first anchor plate 3, the nuts 6 being arranged on the underside of the anchor plate. In FIG. 1 the nuts 6 are hidden by the first anchor plate 3. They are shown, for example, in FIG. 4. Furthermore, nuts 5 are provided. The nuts 5 serve to fix or position the first anchor plate 3, the nuts 5 being arranged on the upper side of the anchor plate.

[0054] The anchoring device 1 further comprises a second anchor plate 7. The second anchor plate can be understood as a bracing or bracing plate. The second anchor plate 7 has drilled holes. Each anchor rod 2 is guided through one of the drilled holes. Two nuts 11 and 12 are screwed onto each anchor rod 2. The nut 12 serves as a seat for the second anchor plate 7, the nut 12 being arranged on the underside of the anchor plate. The nut 11 serves to fix or position the second anchor plate 7, the nut 11 being arranged on the upper side of the anchor plate.

[0055] The first anchor plate 3 is spaced apart from the second anchor plate 7. The perforations in the anchor plates 3 and 7 are located along the edges of the anchor plates 3 and 7.

[0056] Figure 2 shows the anchoring device 1 of Figure 1 with additional components. The anchoring device 1 additionally comprises a pocket form 15. The pocket form 15 is inserted into the central recess 4 of the first anchor plate 3. The flange or folded edge of the pocket form 15 rests flat on the upper side of the first anchor plate 3. The pocket form 15 has an opening through which the anchor rod 2 passes. A nut 5 is then attached to the anchor rod 2 above the flange.

[0057] The pocket formwork 15 serves to form a foundation recess, technically called a pocket (German: kocher, quiver), in the concrete foundation, as will be explained in more detail below.

[0058] FIG. 3 shows the anchoring device 1 with the pocket formwork 15 of FIG.

[0059] First, the anchor device 1 is embedded in the concrete foundation 21 and the first anchor plate 3 is placed far enough above the concrete foundation 21 for the nut 6 of the first anchor plate 3, which is placed under the first anchor plate 3, to be adjusted upward (positive z direction in the figure) and downward (negative z direction in the figure) along the length of the anchor rod 2 by rotating the nut 6. The nut 5 is removed before being leveled. The nut 5 can be screwed back onto the anchor rod 2 later when installing the column for mounting the column base 23 by the centering disk 26.

[0060] Subsequently, the first anchor plate 3 is leveled or aligned by turning the nuts 6 of the first anchor plate 3 arranged on the underside of the anchor plate. Due to the mounting column 22, all the first anchor plates 3 located on the structural part are adjusted to the constructively required height by turning the nuts 6 arranged on the underside of the first anchor plate 3.

[0061] In order to create a pocket 25 in the concrete foundation 21, the pocket formwork 15 is introduced into the central recess 4 of the first anchor plate 3. The pocket formwork 15 is removed again after the pocket 25 has been created in the concrete foundation 21.

[0062] Figure 4 shows a cross section taken along line AA in Figure 3, in which the second anchor plate 7 and the anchor rod 2 are embedded in a concrete foundation 21 below a nut 6 disposed below the first anchor plate 3. The surface of the concrete foundation 21 is spaced from the nut 6 (distance 17).

[0063] Figure 5 shows the encapsulated anchoring device 1 from Figure 3 with the pocket formwork 15 removed again after concreting of the concrete foundation 21, with the nut 5 again resting on the plate. However, the nut 5 is not required at this stage in the method.

[0064] 6 is a schematic perspective view of the fixing device 20. The fixing device 20 comprises a concrete foundation 21, a column 22 (in particular a steel column or a column partially encased in concrete having a column base or column base plate 23) and the anchor device 1 as described above.

[0065] When placing the column base 23 of the column 22 on the first anchor plate 3, a shear key 24 is placed on the underside of the column base. The shear key 24 protrudes into a pocket 25 in the foundation 21. The protruding anchor rod 2 passes through a drilled hole in the column base 23.

[0066] A centering disk 26 is placed on each anchor rod 2 above the column base. Then, a nut 5 is placed on the top of the first anchor plate 3, and the nut 5, which is rotatably mounted on the anchor rod 2, is tightened until it comes into contact with the centering disk 26.

[0067] Figure 7 shows the fixing device 20 of Figure 6 with the addition of an accessory. Between the concrete foundation 21 and the column base 23, a cavity arranged in the form of a pocket 25 (see Figure 8) between the underside of the flange of the column base 23 and the bottom of the foundation recess, is mortared with non-shrink mortar 28 or alternatively concreted.

[0068] FIG. 8 shows a cross-sectional view taken along line BB passing through the fastener of FIG.

[0069] The column base 23 of the column 22 rests on the first anchor plate 3, and a shear key 24 is arranged on the underside of the column base. The anchor rod 2 is guided through an opening in the column base 23. Furthermore, a centering disk 26 is arranged on the upper side of the column base. The centering disk 26 itself is attached to the anchor rod 2 by means of a nut 5.

[0070] The shear key 24 has an I-shaped cross section.

[0071] The second anchor plate 7 and the anchor rod 2 are embedded in the concrete foundation 21 below the nut 6 located below the first anchor plate 3, in the space that exists between the surface of the concrete foundation 21 and the nut 6.

[0072] As mentioned above, the pocket 25 located between the concrete foundation 21 and the column base 23 is mortared or concreted.

[0073] The nut 6 disposed on the underside of the first anchor plate 3 and the first anchor plate 3 are disposed in the pocket 25 .

[0074] FIG. 9 shows another 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 as an anchor template. The first anchor plate 3 has a central recess 4 and drilled holes. Each anchor rod 2 is guided through one drilled hole. One nut 6 is screwed into each anchor rod 2. The nut 6 serves as a seat for the first anchor plate 3, the nut 6 being arranged on the underside of the first anchor plate 3. Furthermore, a nut 5 is provided. In FIG. 9, the nut 6 is hidden by the first anchor plate 3. The nut 5 serves to fix or position the first anchor plate 3, the nut 5 being arranged on the upper side of the anchor plate.

[0075] The anchor device 1 comprises further anchor plates 7, 8, 9 and 10. The further anchor plates can be understood as bracing or bracing plates. Each of the anchor plates 7, 8, 9 and 10 has a drilled hole. Each anchor rod 2 is guided through one of the drilled holes. Two nuts 11, 12 are screwed into each anchor rod 2. The nuts 12 serve as a seat for the anchor plates 7, 8, 9 and 10, the nuts 12 being arranged on the underside of the anchor plates. The nuts 11 serve to fix or position the anchor plates 7, 8, 9 and 10, the nuts 11 being arranged on the upper side of the anchor plates.

[0076] The first anchor plate 3 is spaced apart from the other anchor plates 7, 8, 9 and 10. The perforations in the anchor plates 3, 7, 8, 9 and 10 are located along the edges of the anchor plates 3, 7, 8, 9 and 10.

[0077] The anchoring device 1 of FIG. 9 illustrates another option for constructing the anchoring device.

[0078] Alternatively, at least two other anchor plates 7, 8 may be used instead of the four anchor plates 7, 8, 9 and 10 shown in FIG.

[0079] In this case, the first other anchor plate 7 can be replaced with anchor plates 7, 8 of Figure 9, and the second other anchor plate 8 can be replaced with anchor plates 9 and 10 of Figure 9, and further, the first other anchor plate 7 can be replaced with anchor plates 7 and 9 of Figure 9, and the second other anchor plate 8 can be replaced with anchor plates 8 and 10 of Figure 9.

[0080] Then, two other anchor plates 7,8 have at least one opening, one anchor rod 2 is guided through each opening, and two other nuts fix the two other anchor plates 7,8 on the upper side of the anchor plate 7,8 and on the lower side of the anchor plate 7,8.

[0081] This represents another option for configuring the anchor device.

[0082] As another variant, instead of the four anchor plates 7, 8, 9 and 10 shown in figure 9, at least three other anchor plates 7, 8, 9 can be used. In this case, one of the anchor plates can have two openings, through which an anchor rod 2 is guided. The second and third anchor plates can each have one opening through which one anchor rod 2 is guided. This allows a number of possible combinations of three bracing plates and four anchor rods to be realised.

[0083] 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 number of anchor rods. Each bracing plate can have one, two or more openings or holes for accommodating one, two or more anchor rods depending on how the second anchor plate is divided, which means that there are various possible combinations and arrangements between the number of individual bracing plates and the number of openings for accommodating anchor rods in each bracing plate. Also, the outer contour of the individual bracing plates can be formed according to all known shapes, and the shape of the outer contour of each of the individual bracing plates can be selected individually, obtaining a uniform shape of the outer contour or any possible mixture of the outer contours.
