Description

The invention relates to a device for aligning components, in particular wall elements, wall panes or sleepers in wood construction, with a concrete screw, wherein the concrete screw has a screw shank with a thread and a screw head with a drive configuration. The invention also relates to an arrangement having at least two devices according to the invention.International Laid-Open Specification WO 2022 / 229183 A1 discloses a device for aligning wall elements or wall panes in wood construction, a so-called adjustment screw, wherein the device has a concrete screw with a screw shank with a thread and a screw head. The screw head is circular disc-shaped and has two through-openings arranged at a distance from the screw shank, which openings serve as a drive formation.The invention is intended to improve a device for aligning components and an arrangement.According to the invention, a device having the features of claim 1 or an arrangement having the features of claim 12 is provided for this purpose. Advantageous refinements of the invention are specified in the respective dependent claims.In a device for aligning components, in particular wall elements, wall panes or sleepers in wood construction, with a concrete screw, wherein the concrete screw has a screw shank with a thread and a screw head with a drive formation, a load plate is provided, wherein the concrete screw and the load plate are formed as separate parts, wherein the load plate has a central drive formation which is adapted to the drive formation of the concrete screw, and wherein in the mounted state of the device the central drive formation of the load plate engages the drive formation of the concrete screw or engages in the drive formation of the concrete screw, so that a torque for screwing in or unscrewing the thread of the concrete screw can be transmitted from the load plate to the concrete screw.By forming the load plate and the concrete screw as separate parts, the device according to the invention can be used very flexibly. For example, a commercially available concrete screw can be provided with a load plate. Compared to known devices or adjusting screws, the device according to the invention can be manufactured much more easily, since the concrete screw and the load plate can be manufactured separately and then joined together. By the central drive formation of the load plate engaging or engaging with the drive formation of the concrete screw, although the load plate and the concrete screw are formed as separate parts, a torque for screwing in or unscrewing the thread of the concrete screw can be transmitted from the load plate to the concrete screw. This makes it very simple to adjust or adjust the load plate to a desired level.In a further development of the invention, the central drive configuration of the load plate and the drive configuration of the concrete screw are configured such that the load plate can be tilted relative to the screw shaft about tilting axes perpendicular to the central longitudinal axis of the screw shaft by a small angle, in particular by an angle between +10° and -10°.In this way, for example, the load plate can be aligned exactly horizontally, even if the shank of the concrete screw has not been screwed exactly vertically into a foundation. In addition, a planar contact of the load plate on the aligned component is possible, even if the underside of the component is aligned slightly obliquely to a foundation or, for example, at an angle of slightly more or slightly less than 90° to the shank of the concrete screw.In a further development of the invention, the concrete screw, in particular the head of the concrete screw, has a support flange for placing the load plate, wherein the support flange is formed convexly rounded on its side facing the load plate.By means of a convexly rounded support flange, a secure support of the load plate and thus also a secure force transmission from the load plate to the concrete screw is possible and at the same time it is not necessary for the load plate to be aligned exactly perpendicular to the screw shank of the concrete screw.In a further development of the invention, the central drive configuration of the load plate and the drive configuration of the concrete screw are configured such that, when the load plate is loaded in the direction of the thread of the screw shank, the central drive configuration of the load plate and the drive configuration of the concrete screw clamp towards one another in a state free from play.In this way, in a loaded state, a clearance-free arrangement of the load plate and the concrete screw can be ensured. For example, the drive configuration of the concrete screw and / or the central drive configuration of the load plate is slightly conical, so that when the load plate is loaded in the direction of the foundation into which the concrete screw is screwed, the load plate and the concrete screw become stuck in the region of their drive configurations.In a further development of the invention, the central drive configuration of the load plate is configured as an internal polygon, in particular an internal hexagon, an internal polygon, in particular a torx drive, an RW drive or an AW drive, an internal polygon or an internal star, and the drive configuration of the screw head of the concrete screw is configured as an external polygon, in particular an external hexagon, an external polygon, an external polygon or an external star.The drive configurations of the concrete screw and the load plate can be substantially of any desired configuration. It is particularly advantageous if the concrete screw is designed as a standard concrete screw with a standard drive configuration.In a development of the invention, the load plate, in particular the central drive configuration of the load plate, is configured such that an upper side of the load plate opposite the screw shank is arranged above an upper side of the screw head.In this way, the load plate can also provide a planar support without protruding parts for the component to be aligned in a state connected to the concrete screw.In a further development of the invention, the load plate has an outer drive formation on its outer periphery.For example, rounded depressions for engaging human fingers can be arranged on the outer periphery of the load plate, the outer periphery of the load plate can be designed in the form of an external hexagon for engaging a wrench, or depressions can be arranged, in particular on the outer periphery, in order to be able to engage with a flat tool for adjustment, in particular radially with respect to the outer periphery of the load plate.In a further development of the invention, the load plate consists of steel, in particular stainless steel or galvanized steel, of non-ferrous metals, in particular aluminum, of plastic or of wood material, in particular synthetic resin pressed wood, veneer laminated wood or the like.Depending on the application, the load plate only needs to take over a static load when aligning the component. If, after the alignment of the component, a mortar layer is provided, for example, between an underside of the component and an upper side of the foundation, the load plate and the concrete screw no longer have to take over any static load in the direction of gravity after the mortar has cured. It is thus possible without problems to produce the load plate from a material which only has a limited load-bearing capacity. If the load plate is produced, for example, from plastic or from wood material, in particular synthetic resin pressed wood or veneer laminated wood, the load plate can have an insert made from steel or from non-ferrous metals, in particular aluminum, which then has the central drive configuration of the load plate.In a further development of the invention, the screw shank of the concrete screw is surrounded in sections by a hose-like element made of elastically and / or plastically deformable material, in particular plastic or rubber, in order to provide a seal with respect to rising moisture between a foundation and an underside of the screw head and / or an underside of the load plate in the assembled state.In this way, even if the device according to the invention remains permanently between the foundation and the aligned component, a seal with respect to rising moisture can be provided. To seal against rising moisture in the surface, a sealing film or a sealing layer, in particular made of EPDM, rubber, TPU or other modified plastics, can be attached to the load plate. The sealing film or sealing layer can be self-adhesive on one side or on both sides.In a further development of the invention, the load plate is provided on its upper side with friction-increasing elements, in particular projections.For example, the upper side of the load plate has tips which can penetrate into the underside of a component which rests on the load plate. In this way, a component resting on the load plate can also be fixed in directions perpendicular to the screw shank of the concrete screw.In a further development of the invention, the load plate is provided on its upper side with a seal, in particular a sealing film or sealing disk.In this way, it is possible to prevent water from spreading capillaryally along the load plate and possibly rising capillaryly into the component. The sealing film or sealing disk can be integrated into a planar seal on an underside of the component or can connect to the latter. The sealing film or sealing disk can consist of EPDM, rubber, TPU or other modified plastics and can be formed so as to be self-adhesive on one side or two sides.In a development of the invention, a positioning cone is provided which is arranged on an upper side of the load plate, wherein the upper side of the load plate is provided for the resting of a component and wherein the positioning cone narrows in a direction away from the upper side of the load plate.By providing a positioning cone on the upper side of the load plate, an alignment of the load plate parallel to an upper side of the load plate can be carried out simultaneously with the placement of a component on the load plate. For this purpose, a frustoconical recess must be provided in the component, into which recess the positioning cone can engage and which recess is matched to the external dimensions of the positioning cone. When the component is placed on the load plate, the component is automatically aligned in directions parallel to the upper side of the load plate when the circumferential wall of the positioning cone abuts the inner wall of the frustoconical recess in the component. When placed on the load plate, the component can thus be automatically aligned in the z direction, i.e. in the height direction, and also in the x and y direction, i.e. parallel to the upper side of the load plate.In a further development of the invention, the positioning cone is provided with a concentrically arranged, cylindrical projection.By means of such a circular cylindrical projection, the positioning of the positioning cone in the frustoconical recess of the component can be facilitated. The object on which the invention is based is also achieved by an arrangement having at least two devices according to the invention, a component and a foundation, wherein the component rests with a lower side on upper sides of the at least two load plates and wherein the concrete screws of the devices engage in the foundation.In a further development of the invention, at least one of the load plates is arranged at an angle differing from 90° with respect to the screw shank of the concrete screw assigned to the load plate.In a further development of the invention, in the arrangement according to the invention a positioning cone is provided on at least one of the load plates, wherein the component is provided with at least one frustoconical recess starting from its underside and wherein the positioning cone is accommodated in the frustoconical recess.With the arrangement according to the invention, it is thereby possible to achieve positioning of the component not only in the z direction, that is to say in the height direction, but also in the x and y directions, that is to say parallel to the upper side of the load plate. The alignment of the component in all three axis directions is effected automatically when the component is placed on the load plate. The alignment in the z-direction is defined by the underside of the component resting on the upper side of the load plate. The alignment in the x and y directions is achieved by the cooperation of the positioning cone with the frustoconical recess in the underside of the component. During the placement, the outer wall of the positioning cone interacts with the wall of the frustoconical recess and thereby automatically moves the component into the intended position, in which the outer wall of the positioning cone bears against the inner wall of the frustoconical recess over the entire circumference or at least over the large part of the circumference.In a method for aligning a component on a foundation using at least two devices according to the invention, the following steps are provided: arranging at least two concrete screws of the devices in a foundation, such that the thread of the concrete screws engages at least in sections into the foundation, levelling the upper sides of the load plates to a common level or predefined levels by means of rotating the load plate together with the concrete screw and / or rotating the concrete screw and subsequently placing the load plate and placing the component on the upper sides of the load plates.The method allows the automatic alignment of the component during placement on the device according to the invention in all three axial directions. An alignment in the z direction, i.e. in the height direction, takes place by the underside of the component resting on the upper side of the load plate. The alignment in the x and y directions, i.e. parallel to an upper side of the load plate, takes place by the cooperation of the positioning cone with the frustoconical recess in the lower side of the component. When a component is placed on the load plate, if the positioning cone is not inserted exactly concentrically into the frustoconical recess in the component, the circumferential wall of the positioning cone initially bears on the inner wall of the frustoconical recess only on one side. If the component is then moved further in the direction of the load plate, the component is automatically laterally displaced relative to the load plate until the circumferential wall of the positioning cone rests flat or at least over the major part of its circumference against the inner wall of the frustoconical recess in the component. In a very simple manner, the component can thereby be aligned relative to the device according to the invention.The positioning cone can be made of the following materials, among other things: wood, veneer laminated wood, plastic, fiber-reinforced plastic, synthetic resin pressed wood, concrete, polymer concrete, metal, in particular aluminum, and the like.Further features and advantages of the invention are evident from the claims and the following description of preferred embodiments in conjunction with the drawings.

The concrete screw 12 has a screw shank 18 with a thread 20, which is designed as a concrete thread.The load sheave 14 is provided with a central drive formation 22. The drive formation 22 is formed as a through-opening through the load disk 14 with a hexagonal circumference. The drive formation 22 is matched to a drive formation of the concrete screw 12 on the screw head 16, wherein the drive formation of the concrete screw 12 is formed as an external hexagon, cf. FIG. 2.The load plate 14 is furthermore provided with an outer drive formation 24 in the form of a plurality of rounded recesses distributed uniformly over its outer periphery. This drive formation 24 or the rounded depressions of the drive formation 24 are provided for the purpose that fingers of a human hand, optionally also a suitable tool, engage in the rounded depressions in order to rotate the load plate 14. On the upper side of the load plate 14 a curved double arrow 26 is provided. When the load plate 14 is rotated counterclockwise in FIG. 1, the thread 20 of the concrete screw 12 is unscrewed from a foundation, so that the height of the load plate 14 above the foundation increases. For this reason, a plus is provided in front of the arrow end directed to the right in FIG. 1.When the load plate 14 is rotated in the clockwise direction, the thread 20 of the concrete screw 12 is screwed further into the foundation. The height of the load plate 14 above the foundation is thereby reduced. For this reason, a minus is provided in front of the end of the double arrow 26 pointing to the left in FIG. 1.The device 10 according to the invention is used in such a way that the concrete screw 12 is initially anchored in a foundation, so that the screw head 16 is still arranged above the foundation. The load plate 14 can then be placed with its central drive recess 22 on the drive formation on the screw head 16. The load plate 14 is then rotated to adjust the top of the load plate 14 as seen in Figure 1 to a desired level. Alternatively, the concrete screw 12 can also be rotated until the desired level of the screw head 16 is reached, and then the load plate 14 can be placed on the screw head 16.An upper side of the screw head 16 is arranged slightly below the upper side of the load plate 14 when the load plate 14 is placed on the screw head 16 of the concrete screw 12. A component to be aligned, which is placed on the upper side of the load plate 14, see for example FIG. 6, can thereby rest on the load plate 14 without an upper side of the screw head 16 contacting an underside of the component. The component can thus be displaced even slightly on the upper side of the load plate 14 in a simple manner. However, it can also be provided within the scope of the invention that the screw head 16 protrudes beyond the upper side of the load plate 14, for example when no displacement of the component on the load plate 14 is required in directions perpendicular to the screw shank 18.FIG. 2 shows the device 10 of FIG. 1 in an exploded state. In the state of FIG. 2, the load plate 14 has not yet been placed on the screw head 16 of the concrete screw 12. The central drive formation 22 of the load plate 14 is, as has been explained, in the form of a through-opening with a boundary in the form of a regular hexagon. The drive formation 22 can be cylindrical, so that the boundary is formed parallel to a central longitudinal axis of the drive formation 22. The boundary of the drive formation 22 can also be formed slightly conically or in the shape of a truncated cone, so that the through-opening forming the drive formation 22 expands slightly downwards in FIG. 2. This not only facilitates the placement of the load disk 14 on the screw head 16 of the concrete screw 12, but with a corresponding configuration it can also be achieved that the drive configuration 22 can easily be placed on the drive configuration of the screw head 16 and then, when the load disk 14 is pressed further downward, in the direction of the screw head 16, is clamped with the drive configuration on the screw head 16.In the embodiment shown, however, the central drive formation 22 of the load plate 14 is formed such that it is seated with a certain clearance on the drive formation on the screw head 16. However, the play is not so large that the load disk 14 could be rotated relative to the screw head 16, but the play is just so large that the load plate 14 in the state in which it is placed on the screw head 16, see FIG. 1, can be tilted by a small angle about tilting axes perpendicular to the central longitudinal axis of the screw shank of the concrete screw 12, see FIGS. 6 band 6 c.The concrete screw 12 can be designed as a commercially available concrete screw. In the embodiment shown, the concrete screw 12 has a support flange 28 adjoining the screw head 16 in the direction of the screw shank 18. This support flange 28 provides a stop when the load plate 14 is placed on the screw head 16 and is furthermore, see FIG. 5, convexly rounded in order to ensure a secure support of the load plate 14 on the support flange 28 even when the load plate 14 is tilted relative to the shank of the concrete screw 12.FIG. 3 shows a side view of the device 10 in the state of FIG. 2, in which the load plate 14 is therefore still arranged above the screw head 16 of the concrete screw 12.FIG. 4 shows a plan view of the load plate 14. It can also be seen that the outer drive formation 24 has rounded recesses 30 distributed at a uniform distance over the outer periphery of the load plate 14. Finally, the curved double arrow 26 can be seen in FIG. 4.FIG. 5 shows a sectional side view of the concrete screw 12 of FIGS. 1 to 3, the screw head 16 being provided with a drive formation 32 in the form of an external hexagon, the drive formation 22 being formed in the usual manner.Between the screw head 16 and the screw shank 18 there is arranged the support flange 28, the upper side 34 of which is convexly rounded. The upper side 34 merges into the side surfaces of the drive formation 32 arranged parallel to the central longitudinal axis of the screw shank 18.Since the central drive formation 22 of the load disk 14, see for example FIG. 4, has an inner circumference which is somewhat larger than the outer circumference of the drive formation 32, the load disk 14, when it is placed on the screw head 16, can be tilted slightly relative to the central longitudinal axis of the screw shank 18, for example by an angle of ±10°. This tilting is facilitated by the convexly rounded upper side 34 of the support flange 28.FIG. 6 shows three sectional views of an arrangement with the device 10 according to the invention, a foundation 40 and a component 42 resting on the load sheave 14 of the device 10 in different states. In the state of FIG. 6 a, the shank of the concrete screw 12 has been screwed in perpendicularly to an upper side of the foundation 40. The load sheave 14 is arranged perpendicular to the central longitudinal axis of the screw shank of the concrete screw 12. An underside of the component 42 rests on the upper side of the load sheave 14 and is arranged perpendicular to the central longitudinal axis of the screw shank of the concrete screw 12. An upper side of the foundation 40 is generally not planar but slightly undulated in reality. For example, the foundation 40 is designed as a floor plate of a building. A level of the upper side of such a base plate is not exactly the same, but can vary over several centimeters over the size of the base plate, see also FIG. 7. the illustration of FIG. 6 is therefore purely schematic and in particular the illustration of the upper side of the foundation 40 is purely schematic.FIG. 6 bshows a state in which the screw shank of the concrete screw 12 has been screwed into the foundation 40 again perpendicularly to the upper side of the latter. However, in the state of FIG. 6 b, the load plate 14 is slightly tilted and is thus arranged obliquely to the central longitudinal axis of the screw shank of the concrete screw 12. Specifically, in the side view of FIG. 6 b, the left side of the load plate 14 is arranged lower than the right side of the load plate 14. An underside of the component 42 is arranged slightly obliquely to the central longitudinal axis of the screw shank of the concrete screw 12. A side of the underside of the component 42 on the left in FIG. 6 bis arranged closer to the foundation 40 than the side of the underside of the component 42 arranged on the right in FIG. 6 b. The device 10 according to the invention can thereby ensure a planar support of the underside of the component 42 on an upper side of the load plate 14 even if an underside of a component 42 to be aligned is not exactly perpendicular to a central longitudinal axis of the screw shank of the concrete screw 12.FIG. 6 cshows a state in which a central longitudinal axis of the screw shank of the concrete screw 12 has been screwed obliquely into the foundation 40 by an angle α to the vertical. An underside of the component 42 lies flat on the upper side of the load plate 14, and the underside of the component 42 and the load plate 14 are arranged perpendicular to the vertical. The load plate 14 is arranged at an angle α obliquely to a line which runs perpendicular to the central longitudinal axis of the screw shank of the concrete screw 12. The oblique bearing of the load plate 14 on the screw head of the concrete screw 12 is made possible by the configuration according to the invention, in particular in that the central drive formation 22 of the load plate 14 rests with play on the drive formation 32 of the screw head 16 and in that an upper side 34 of the bearing flange 28, see FIG. 5, of the concrete screw 12 is convexly rounded.With the device according to the invention, an angular offset of a central longitudinal axis of the screw shank of the concrete screw 12 with respect to the vertical and a deviation of an underside of the component 42 from the horizontal can thereby be compensated.FIG. 7 shows an arrangement 50 according to the invention with two apparatuses 10A, 10B according to the invention. The devices 10A, 10B are identical to the device 10 which was explained with reference to FIGS. 1 to 6. The concrete screws of the devices 10A, 10B are screwed into the foundation 40 at a distance from one another. In FIG. 7, it is schematically and in an exaggerated manner shown that an upper side of the foundation 40 is not planar but rather has different levels. In the illustration of FIG. 7, the level of the upper side of the foundation 40 changes by a height H. At the location of the device 10A, an upper side of the foundation 40 is thus arranged by the height H above the level of the upper side of the foundation 40 at the location of the device 10B.The component 42 is shown in sections in FIG. 7 and is designed, for example, as a wall element, wall pane or also threshold wood. The component 42 is to be arranged on the foundation 40 in such a way that an underside, optionally also an upper side of the component 42, is aligned exactly horizontally.To achieve this, the top surfaces of the load plates 14 of the devices 10A, 10B are set at the same level. For this purpose, as already explained, the concrete screws 12 of the devices 10A, 10B are first screwed into the upper side of the foundation 40 at a distance from one another. After the load plates 14 have been placed on, the load plates 14 are then rotated about the central longitudinal axis of the respective screw shafts until the upper sides of the load plates 14 are arranged at a common level. This state is shown in FIG. 7. Alternatively, the upper sides of the load plates 14 can also be set to predetermined, different levels, for example if the lower side of the component 42 has steps or the like. The concrete screws 12 can also be adjusted before the load plates 14 are placed on, in such a way that the support flanges 28 of the concrete screws 12 are arranged at the same level or defined levels.The component 42 can now be placed on the upper sides of the load plates 14 and is thus aligned exactly horizontally with its lower side.After the alignment of the component 42, an intermediate space between the underside of the component 42 and the upper side of the foundation 40 can be stuffed, for example stuffed with mortar, which then solidifies. In the consolidated state of the mortar, the devices 10A, 10B then no longer have to assume a static function.Figure 8 shows a concrete bolt 52 according to an embodiment of the invention. The concrete screw 52 is designed identically to the concrete screw 12 of FIGS. 1 to 7 in and of itself, but has a tubular element 54 which surrounds the screw shank 18 below the bearing flange 28 and bears against the screw shank 18. Within the scope of the invention, the element 54 can be designed hose-like, for example not cylindrical, but in the form of a bellows or sealing arrangement. A lower side of the tubular element 54 terminates shortly before the beginning of the thread 20 on the shank of the concrete screw 52; the tubular element 54 is consequently arranged in a section of the screw shank 18 in which it has a smooth-surfaced outer side. Within the scope of the invention, however, the tubular element 54 can also extend as far as into the region of the thread 20 and / or the thread 20 can go as far as directly under the support flange 28.FIG. 9 shows a sectional view of an arrangement with the foundation 40, the concrete screw 52 of FIG. 8, a load plate 14 placed on the screw head 16 of the concrete screw 52, and a component 42 resting on an upper side of the load plate 14.The foundation 40 is provided on its upper side with a seal 56, for example a bitumen sheeting. The seal is intended to prevent capillary ascending water. At the point where the screw shank of the concrete screw 52 passes through the seal 56, the seal 56 is interrupted. In order to nevertheless prevent moisture from rising from the foundation 40 or from an upper side of the seal 56 as far as the component 42, an underside of the tubular element 54 rests on an upper side of the seal 56. Optionally, an underside of the tubular member 54 is lightly pressed against the top of the seal 56. The tubular element 54 arranged around the screw shank is intended to seal the local opening in the seal 56, in other words in the sealing plane, so that no bottom staling moisture presses through the seal 56. Although the attachment of the tubular member 54 is not necessary in most cases, the attachment of the tubular member 54 provides a solution for moist substrates.The tubular element 54 is elastically and / or plastically deformable. As a result, a distance between an underside of the support flange 28 and an upper side of the foundation 40 or an upper side of the seal 56 can vary without the sealing function of the tubular element 54 being impaired.FIG. 10 shows a state of the arrangement of FIG. 9, in which the elastic and / or plastic deformability of the tubular element 54 is illustrated. The load plate 14 is arranged in the state of FIG. 10 substantially closer to the upper side of the seal 56 of the foundation 40 than in the state of FIG. 9. the tubular element 54 has been deformed plastically and / or elastically. Even in the deformed state of FIG. 10, an underside of the tubular element 54 abuts an upper side of the seal 56 of the foundation 40 and thereby prevents moisture from being able to rise from the foundation 40 or from an upper side of the seal 56 into the component 42.FIG. 11 shows the device 10 according to the invention from FIG. 1. Above the device 10, the z-direction or height direction and the y-direction and the x-direction are drawn in, wherein the y-direction and the x-direction run parallel to the upper side of the load plate 14.With the device 10, an alignment of a component placed on the load plate 14 in the z-direction is possible. When the underside of the component is placed on the upper side of the load plate 14, the component is automatically aligned in the z direction. The device 10 can thus be used for adjusting a component in the z direction. In the y and x directions, after the device 10 is arranged on a foundation or the like, an alignment of the component is only possible to the effect that it is arranged in the exactly provided position on the load plate 14. Such an alignment of both the device 10 and the component on the load plate 14 must be effected manually. By light hammer blows, the component resting on the load plate 14 can then also be aligned in the y and x directions.FIG. 12 shows a further device 110 according to the invention, which corresponds largely to the device of FIG. 11. A positioning cone 112 is additionally arranged on the load plate 14. The positioning cone 112 has, concentrically to its central longitudinal axis, a circular cylindrical projection 114 which is placed on the tapered end of the positioning cone 112. Within the scope of the invention, the circular cylindrical projection can also be omitted. The circular cylindrical projection can be formed, for example, by means of a spacer sleeve which is screwed onto a metric thread of the concrete screw. This spacer sleeve then holds the positioning cone on the load plate against displacement. The spacer sleeve can protrude beyond the upper side of the positioning cone, can terminate flush with the upper side of the positioning cone or can be arranged recessed in the positioning cone. The positioning cone narrows in a direction away from the top side of the load plate 14.A lower side of a component to be placed on the load plate 14, cf. FIG. 17, is provided with a frustoconical recess which is matched to the positioning cone 112 in depth, diameter and cone angle. Expediently, the cone angle of the frustoconical recess corresponds to the cone angle of the positioning cone 112 and the inner diameters of the frustoconical recess are dimensioned such that the positioning cone 112 can be completely accommodated in the frustoconical recess, but there is only a very slight clearance between the outer wall of the positioning cone 112 and the inner wall of the frustoconical recess.When a component is placed on the device 110, the positioning cone 112 consequently penetrates into the frustoconical recess in the underside of the component, so that as a result, cf. FIG. 17, the component is automatically aligned relative to the load plate 14 in the x direction and in the y direction.With the device 110 according to the invention, a component placed on the load plate 14 can thus be automatically aligned in the z direction. This alignment in the z-direction, i.e. in the height direction, is effected automatically in that the underside of the component rests on the upper side of the load plate 14. In addition, the positioning cone 112 brings about automatic alignment in the x direction and y direction of the component relative to the device 110 when the positioning cone 112 penetrates into the frustoconical recess on the underside of the component, cf. FIG. 17.FIG. 13 shows a schematic sectional view of the device 110 of FIG. 12 It can be seen that the positioning cone 112 rests with its underside on the surface of the load plate. In the embodiment shown, the circular cylindrical projection 114 is formed integrally with the positioning cone 112. Within the scope of the invention, the circular cylindrical projection can also be omitted. The positioning cone 112 can be connected to the upper side of the load plate 14 in any desired manner, for example glued to the load plate 14 or can also be formed integrally with the load plate 14. It is of course also possible to connect the positioning cone 112 to the load plate 14 by means of screws. Alternatively, the concrete screw 12 may have a protrusion extending from the head of the concrete screw 12 and extending into a matching bore in the positioning cone 112.In the embodiment shown, the head of the concrete screw 12 projects a certain distance beyond the top side of the load plate 14. On its underside, the positioning cone 112 has, for this reason, a recess 115 into which the upper side of the head of the concrete screw 12 projects. The positioning cone 112 is thus automatically arranged in the correct position on the load plate 14 when the upper side of the head of the concrete screw 12 extends into the recess 115.FIG. 14 shows a further embodiment of the positioning cone 112. The recess 115 is designed in the shape of a truncated cone and can interact, for example, with a conical head of matching design or a conical extension on the head of the concrete screw 12 in order to position the positioning cone correctly on the load plate 14.Within the scope of the invention, the positioning cone 112 can have a central bore. A projection which extends from the head of the concrete screw 12 can extend into such a central bore in order to position the positioning cone 112 in the correct position on the load plate 14. Alternatively, a screw or a fastening bolt can also be inserted into the central bore of the positioning cone 112, which bolt is then screwed into a matching threaded bore in the head of the concrete screw 112.FIG. 15 shows a sectional representation of a component, for example a lower sleeper of a wood wall 118, which is provided with a frustoconical recess 120 which originates from an underside of the wood wall 118. The frustoconical recess 120 continues through a cylindrical bore 122. As a result, a through-opening is provided through a section of the wood wall 118, for example a through-opening through a lower sill of the wood wall 118. Within the scope of the invention, the cylindrical bore 122 does not have to extend through a section of the wood wall 118, but can also be designed as a blind hole.The cone angle α, the initial diameter d1and the final diameter daof the frustoconical recess 120 are matched to the cone angle, the initial diameter and the final diameter of the positioning cone 112, such that the positioning cone 112 can be completely accommodated in the frustoconical recess 120, but there is only a slight clearance between the outer wall of the positioning cone 112 and the inner wall of the frustoconical recess 120. As a result, when the wood wall 118 is pushed onto the device 110, in other words when the frustoconical recess 120 is pushed onto the positioning cone 112, the component, that is to say the wood wall 118, can be automatically aligned relative to the device 110. This alignment takes place in the z-direction in that the underside of the wood wall 118 comes to lie in sections on the upper side of the load plate, and in the x-direction and in the y-direction in that the wood wall 118 is laterally displaced by the mutually rising frustoconical outer wall of the positioning cone 112 and the likewise frustoconical inner wall of the frustoconical recess 120 until the positioning cone 112 is completely accommodated in the frustoconical recess 120. A lateral displacement of the wood wall 118 does not naturally take place when the positioning cone 112 is inserted exactly concentrically into the frustoconical recess 120. The diameter of the circular cylindrical projection 114 of the device 110 is indicated by di, cf. FIGS. 12 and 13.FIG. 16 shows several views of a positioning cone 112. In contrast to the positioning cone 112 of FIGS. 13 and 14, the positioning cone 112 of FIG. 16 is provided with a central through bore. However, the positioning cone 112 of FIG. 16 is configured identically to the positioning cones 112 of FIGS. 13 and 14.Within the scope of the invention, as already explained, the positioning cone 112 can be designed without a central bore and then fixed in any desired manner on the upper side of the load plate.FIG. 17 shows several successive steps a, b, c and d during the placement of a component, for example a wood wall 118, onto the device 110 which is fastened in a foundation 124.The wood wall 118 is provided with a lower sill 126, the sill 126 being provided with the frusto-conical recess 120 and the cylindrical bore 122, which have already been explained with reference to Fig. 15. The frustoconical recess 120 and the cylindrical bore 122 form a through-opening which passes completely through the threshold 126. Within the scope of the invention, as stated, the cylindrical bore 122 can also be formed as a blind hole.In state a and also in state b, the threshold 126 is still arranged above the end of the cylindrical protrusion 114 of the device 110.Starting from state a, the wood wall 118 is lowered into state b and further into state c until the circular cylindrical projection 114 and the positioning cone 112 are arranged at least in sections in the frustoconical recess 120. If the upper end of the circular cylindrical projection 114 abuts the inner wall of the frustoconical recess 120, the wood wall 118 is thus already aligned parallel to the load plate of the device 110. For this purpose, the cylindrical projection can have a tapered and end-rounded tip in order to facilitate this alignment. The frustoconical recess 120 and the cylindrical bore 122 in the sleeper 126 are dimensioned such that when the circular cylindrical projection 114 is inserted in sections into the cylindrical bore 122, the large, lower end of the frustoconical recess 120 automatically reaches the small, upper end of the positioning cone 112 when the wood wall 118 is lowered, see state c.This state c has the result that, when the wood wall 118 is lowered further, starting from the state c, the wood wall 118 or the sleeper 126 of the wood wall 118 is automatically displaced parallel to the load plate 14, that is to say in the x direction and y direction, until, in the state d, an underside of the sleeper 126 rests on the load plate 14. This is effected by the cooperation of the frusto-conical surfaces of the positioning cone 112 and the frusto-conical recess 120. It can be seen from the representation of state d that an outer wall of the positioning cone 112 now lies flat against the inner wall of the frustoconical recess. It can also be seen that the circular cylindrical projection 114 is aligned concentrically with the cylindrical bore 122, but only projects into the cylindrical bore 122 in sections. It can also be seen that the underside of the sleeper 126 rests on the upper side of the load plate 14. In the state d, the wood wall 118 is thus oriented in the intended manner relative to the device 110 and relative to the foundation 124, namely in the height direction, i.e. in the z direction, and also parallel to an upper side of the foundation 124 or parallel to the load plate 14, i.e. in the x direction and in the y direction.Figure 18 shows three examples a, b, c of how a wood wall 118 may not be deformed or deformed and how such deformation may be corrected by means of the devices 110 according to the invention.FIG. 18 ashows an undeformed wood wall 118, which is therefore exactly planar.FIG. 18 bshows a wood wall 118 which is deformed, for example during production, storage or transport of the wood wall 118, and which shows a continuous curvature and thus a deviation from the ideal shape in FIG. 18 a.According to FIG. 18c, the wood wall 118 is deposited on three devices 110. The curvature of the wood wall 118 in Fig. 18b is thereby automatically corrected. This is achieved by the underside of the wood wall 118 being pushed onto the positioning cones of the devices 110, as was explained with reference to FIG. 17.FIG. 18 cshows that the curvature of the wood wall 118 in FIG. 18 bhas been automatically corrected when placed on the positioning cones of the devices 110 and the wood wall 118 is again exactly flat in the state in which it is placed on the devices 110.Figure 19 shows several different uses of the inventive devices 110. The devices 110 may be placed on a floor of a house 130, the devices 110 may be placed on a eaves 132 of a building, the devices 110 may be deployed when placing an elevation 134 on an existing building, and the devices 110 may be used to place a facade 136 in front of an existing building. In all cases, the devices 110 or 10 according to the invention can be oriented at least in the z direction, i.e. in the height direction, or even in all three spatial directions, i.e. in the x, y and z directions.FIG. 20 shows a sectional illustration of the foundation 124 of FIG. 17 with a device 110 inserted into an upper side of the foundation 124. Prior to inserting the jig 110 into the foundation 124, a waterproof sheet 140 is laid on a portion of the top surface of the foundation 124, and the jig 110 is screwed into the foundation 124 through the waterproof sheet 140. The watertight foil 140 provides a seal against moisture that rises capillary from the foundation 124.The watertight film 140 is laid a certain distance around the vertical outer boundary wall 142 and fastened to this outer boundary wall by means of a bitumen adhesive tape or another adhesive tape.A further section of the watertight film 140 is folded vertically upwards and likewise provided with a bitumen adhesive tape 144 or another adhesive tape. This portion of the waterproof sheet 140 is provided to be adhered to an inner side of a wall member, as shown in FIG. 21.Filling aids 146, for example made of plastic, in particular of foamed plastics, in particular in the form of sponge rubber strips or sponge rubber tubes, are provided on both sides of the device 110. The upper sides of the filling aids 146 are situated at the height of the upper side of the load plate 14 or slightly below the upper side of the load plate 14.Before the wall element 148 is placed on the device 110, see FIG. 21, a flowable swelling mortar 150 is introduced between the filling aids 146. The flowable swelling mortar can be distributed uniformly and does not have to be filled in a complicated manner laterally into a joint between the underside of the wall element 148 and the upper side of the foundation 124. A surface of the swelling mortar 150 is at most at the height of the top side of the load plate 14 before the wall element 148 is placed on.Following the state of FIG. 20 in which the swelling mortar 150 has already been filled, the wall element 148 is placed onto the device 110 in the described manner and, as a result, cf. FIG. 17, automatically aligned relative to the device 110 and thus relative to the foundation 124.After placement, the adhesive tape 144 is adhered to the inside of the wall element 148. The swelling mortar 150 cures and in this case swells in particular. In the state of FIG. 21, a watertight and wind-tight seal is thereby created between an underside of the wall element 148 and an upper side of the foundation 124.References included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
