Description

The subject of the invention is a support arrangement for receiving and supporting posts, technical structures and masonry according to the preambles of claims 1 and 7.

In the present application, a post is used to denote either an elongated support element installed vertically in buildings or a free-standing elongated, vertical structural element connected to the subsurface.

In the present application, a post support arrangement is understood to mean a device for fastening and supporting a structure, in particular a rod-shaped, post-shaped or tubular object.

Masonry is a component or structure made of natural or artificial stones as a solid structure. The masonry consists of individual pressure-resistant elements (natural stones or artificial stones such as clay bricks, masonry bricks or hollow blocks).

In the present application, a wall support arrangement is understood to mean a device for fastening and supporting a wall, in particular a flat, vertically extending wall.

For the permanent installation of such a support arrangement, a peg is preferably inserted into the ground. A peg is preferably to be understood as a round metal rod, the outer jacket of which is provided with a thread profile over the entire length of its course.

Such pegs can, regardless of their material properties, not only be built on the basis of a round rod, but also have an angular or oval cross-section or, in addition to a continuously smooth surface, also have a connection of several profiles.

Because of their thread course (comparable to a drill thread), ground nails can be used for drilling-like penetration of materials which, according to their morphology, allow the penetration of such a nail.

This means that pegs can be driven into layers of material made of sand, rubble, snow, ice, gravel, stone or their mixtures with one another.

The ideal case is a primer made of e.g. snow, ice, sand, earth or clay, whereby a peg follows the pulling direction of its thread profile when it is screwed in and finds the desired hold in the primer.

The insertion of the peg into the subsoil depends on the morphological nature of the subsoil and can optionally be carried out by pre-drilling in the intended depth and inclination. This is also possible without pre-drilling, in that the external thread of the peg takes on the function of a drill thread and works into or loosens from the ground under vertical pressure or tension.

The stability of a masonry or a general structural device is characterized by the statics, but also by the foundation of the same. If one of these components is neglected during the planning or creation of the construction project, the safe maintenance and thus the function of the entire construction project is no longer guaranteed.

Even after the completion of a masonry or a structural device, the original function can be weakened or canceled by external influences. Gradual or sudden changes in the building fabric can, sooner or later, impair the function of the affected trade and thus lead to a high security risk.
Repair work, insofar as it is still possible at all, can only be achieved in such cases by removing partial structures of the masonry or the central foundation and replacing them with great effort.

Such complex repair work is uneconomical in comparison to a general new construction and can significantly impair the functions originally intended for the masonry for the duration of its execution.

It is not uncommon for such aid measures to be only of short success and the masonry, which has weakened in its substance, sooner or later has to be completely removed and then completely rebuilt.

For such structural repair measures of this magnitude, the inclusion of an already existing foundation is necessary in most cases. If this can no longer be used or if it has to be partially replaced, conventional ground anchors must be used, which, as earth screws or impact elements, are able to centrally absorb the pressure of loads and anchor them in a narrow catchment area.

At the same time, such an assembly can only be carried out if there is a vertical free space above the peg to be inserted or can be opened so that such a screw or hammer nail can be screwed in or hammered in with a hydraulic or similar device. Such framework conditions are only given in rare cases.

The use of pegs for a support arrangement is also known for stiffening wooden structures, wooden piles, overhead line masts and the like, which have become damaged as a result of the weather. For this purpose, a concrete body is used in a pit next to the defective mast, which has a metal support structure at its upper end, which is screwed to the mast. The damaged part of the mast is then sawn out below the fastening point so that the mast is now supported with the iron struts of the concrete body.

For the stabilization of posts, such as fence posts, pegs are also used, as it is for example with the support arrangement of the US 278 220 A is shown. The mast to be fixed has a flat foundation, with which the mast stands on the ground. This flat foundation has slots on its outer arms through which the peg can be driven in order to anchor the mast to the ground.

• eine Pfostenstützstruktur, die in den Untergrund eingebracht und dazu angepasst ist, das untere Ende des Pfostens aufzunehmen,
• eine unterirdische Anordnung von Erdnägeln, die mit der Pfostenstützstruktur verbunden ist und aus drei voneinander beabstandeten Tragarmen besteht, die mit der Anordnung von Erdnägeln verbunden sind und sich im Winkel zur Achse des Pfostens erstrecken. Dabei ist im Tragarm mindestens eine Durchgriffsöffnung für mindestens einen Erdnagel angeordnet, der durch die Durchgriffsöffnung hindurch in einem Winkel zur Achse des Tragarms in den Untergrund getrieben werden kann.

So also shows U.S. 2,826,281 A a post support assembly for receiving and supporting a post for anchoring in the ground comprising:

• a post support structure that is sunk into the ground and adapted to receive the lower end of the post,
• an underground peg assembly connected to the post support structure and consisting of three spaced apart support arms connected to the peg assembly and extending at an angle to the axis of the post. At least one penetration opening for at least one peg is arranged in the support arm, which can be driven into the ground through the penetration opening at an angle to the axis of the support arm.

The post has a kind of sleeve to which the receiving arms are welded like wings. Compared to the already mentioned US 278 220 A the difference is that the receiving sleeve or the foundation is inserted into the subsoil below the top of the terrain. For this purpose, a hole is first dug into which the post with the post support structure is placed, which is then provided with the receiving sleeve. Subsequent insertion of the pegs on the side of the sleeve creates an anchor arrangement and then the previously dug hole in which the post is located is filled in again, so that the anchor arrangement is buried in the ground.

With these known foundations, however, there is the disadvantage that they can only be introduced into the ground in the immediate vicinity of the post, ie near the central longitudinal axis. Sufficient stabilization cannot be guaranteed if very large forces, such as those caused by wind, act on the post and which can only be insufficiently absorbed by the pegs branching off the post and the post can tip over.

The present invention is therefore based on the object of designing a support arrangement for receiving and supporting posts and masonry in such a way that there is a foundation that is easy to introduce into the subsurface and dimensioned according to the expected forces.

The object is achieved according to the invention by the features of the independent patent claims 1 and 7, while advantageous configurations and developments of the invention can be found in the subclaims.

An advantageous feature is that the support arm protruding from the support arrangement is designed as a flat holding plate which has several penetration openings in each of which a movable spherical body is arranged through which a peg is passed and that the spherical body is between an upper holding plate and the lower flat holding plate is clamped in a secured position.

The arrangement according to the invention thus serves as a decentralized foundation and securing system, which can absorb the so-called gravity pressure in any lateral positioning to a post or masonry and can derive it laterally with any direction and distance in a simple manner or over several vertical planes.
Thus, a completely new and at the same time relieving foundation is possible. Horizontal loads can be transferred into the subsoil by means of pegs that are guided through the retaining plate and inserted into the subsoil

Through the use of holding plates which are arranged outside the longitudinal axis of the post support structure, or of horizontal support units which are arranged outside the longitudinal axis of the masonry support structure, the acting force is distributed over a large area. The support arrangement according to the invention is particularly suitable for transferring large loads.

The upper holding plate, which is screwed to the lower holding plate, also has an opening through which the spherical body partially protrudes. The spherical body has a holding stub with an internal thread through which a rotational movement applied to the holding connector can be transmitted to the thread of the peg.

The post support structure thus consists of a carrier unit which is vertically inserted into the subsurface and on which at least two retaining plates are mounted on the sides.

Steel girders made of weatherproof structural steel (e.g. Corten steel) are preferably used for the support arrangement as a carrier unit. Steel girders are either rolled or welded profiles that are available in various sizes and designs. These are load-bearing components that are particularly robust due to their nature, have a high load-bearing capacity and load-bearing capacity and can be used flexibly. So-called double-T beams are preferably used, which have an upper flange and a lower flange connected to it via a web. However, the invention is not restricted to this. Thus, in a further embodiment of the invention, supports can also be used which, for example, have a U-profile.

In the present invention, these flanges are generally referred to as belts, the upper and lower belts of a beam with a double-T-shaped cross-section, which are held at a distance from the continuous web, are referred to as belts in concrete, wood and steel construction. Above all, these belts absorb the load from bending.

On such a vertical support, which is the basic component of the post support structure according to the invention, the retaining plates can now be attached laterally in any number, which have any number of openings through which the pegs (preferably made of steel) in the form of smooth round rods or Threaded rods can be inserted in any orientation using simple screwing or striking tools and can be firmly connected by screwing or welding. Thus, in addition to the flat support of the retaining plates on the ground, there is additional stabilization in the ground through the introduction of the pegs into the ground.

Firmly connected to the post to be secured, a highly effective, inherently variable foundation has been created, which dissipates the gravitational pressure of the post to the side so that the overall statics of the post is relieved and the support of the retaining plates in the ground is transferred to the post and thus stabilized.

The holding plates, which are mounted vertically starting from the longitudinal axis of the carrier unit, have a corner connection as a means of stiffening the corner area at the contact point between the carrier and the holding plate. This corner connection is used to introduce and distribute introduced loads, to increase the corner stiffness, to produce a rigid corner and is known in steel construction under the name Vouten.

Thus, the power flow can be evenly distributed and the bending stresses decrease, which is important for dimensioning the weld seams and for the shear flow in the web plate of the carrier unit.

In a further embodiment of the invention, on the section of the carrier unit which protrudes above ground from the top edge of the terrain, a flange plate enclosing the carrier unit for receiving a pipe element likewise having a flange is mounted.

In a second embodiment of the invention, masonry can also be supported with the support arrangement. To achieve this, at least one vertical support unit (preferably made of steel) is docked to the masonry to be supported as a basic bracket, i.e. firmly connected. For this purpose, the vertical support is positioned either above the surface of the earth or partially in the subsurface, whereby a support unit, which is partially installed in the subsurface, can already take on an important foundation function under the included surface of the earth.

• der untere Teil einer Mauerwerkstützanordnung in den Untergrund eingebracht ist und der obere Teil mit dem zu stützenden Mauerwerk verbunden ist,
• eine unterirdische Erdnagelanordnung zur stabilen Fixierung der Mauerwerkstützstruktur im Untergrund vorhanden ist, bestehend aus mindestens einem Tragarm, der sich senkrecht zur vertikalen Achse des Mauerwerks erstreckt, in dem mindestens eine Durchgriffsöffnung für mindestens einen Erdnagel angeordnet ist, der durch die Durchgriffsöffnung hindurch in einem Winkel zur Achse des Tragarms in den Untergrund getrieben ist.

The wall support arrangement according to the invention for ground-based support of masonry that is at least partially above ground is characterized in that

• the lower part of a masonry support arrangement is inserted into the ground and the upper part is connected to the masonry to be supported,
• an underground peg arrangement for stable fixation of the masonry support structure in the subsurface is present, consisting of at least one support arm which extends perpendicular to the vertical axis of the masonry, in which at least one penetration opening for at least one peg is arranged, which through the penetration opening at an angle to Axis of the support arm is driven into the ground.

The wall support arrangement is also characterized in that
the at least one support arm is designed as a profiled holding plate, which has several penetration openings, in each of which a movable spherical body is arranged, through which the respective peg is passed and that the spherical body is clamped in a secured position between an upper holding plate and the lower flat holding plate.

The wall support arrangement is also characterized in that the masonry support structure consists of a carrier unit that is vertically inserted into the ground, on which at least one further carrier unit is mounted on the side and that a corner connection is mounted to stiffen the corner area between the carrier unit and the at least one further carrier unit , which connects the carrier unit and carrier unit diagonally.

The wall support arrangement is also characterized in that further carrier units are connected to one another via a screw connection, which are installed at a distance from the vertical carrier unit.

Starting from this vertical support unit, lateral support units can now be mounted in any number and at any height, preferably horizontally and also at any angle of incidence on the vertical support unit. For such a combination of a first carrier unit and at least one further carrier unit (secondary carrier), the at least one further carrier unit can be placed on the first carrier or connected to it at the same level.

In addition, a diagonal reinforcement (corner connection) can be installed between the vertical and horizontal beams, which ensures the greatest possible angular stability.

Thus, in a further development of the invention, it is possible at any time to supplement the horizontal support unit with further additional supports, both in the vertical and in the horizontal plane, and thus to create a type of lattice structure. The additional carriers have any number of penetration openings through which the pegs can be inserted in any orientation, using simple screwing or striking tools, and firmly connected by screwing or welding. This creates a highly effective and inherently variable foundation that is firmly connected to the masonry to be secured, which can divert the gravitational pressure of the masonry involved laterally, so that the overall statics of the masonry is relieved and the continuously stable lattice structure is transferred to the masonry and stabilized.

In addition to the flat support of the vertical support units on the ground, there is additional stabilization by fixing the pegs in the ground. In this way, the load that occurs on a building can be diverted into the subsoil. The dimensioning of such a foundation depends on the amount of loads (e.g. dead weight, wind and snow loads) as well as on the structure of the supporting structure and the load-bearing capacity of the subsoil. Thus normal and lateral forces as well as additional moments can be introduced into the foundations. A screw and / or weld connection creates more or less rigid connections between the individual components.

A corner connection is preferably mounted between the vertical carrier unit and the horizontal carrier unit attached to it, which serves to introduce and distribute introduced loads, to increase the corner stiffness and to produce a rigid corner. Such a corner connection is also known in steel construction under the designation haunch and is used in the foundation according to the invention to enlarge the Kraftumlenkbereiches to ensure the rigidity of the frame corner, the interconnected support units.

The components required for such a decentralized foundation and securing system are easy to handle, compared to other structural engineering methods, with high economic efficiency.
If the vertical as well as horizontal support units are laid flat or only partially visible under the outer wall of the structural engineering device or the surface of the earth, such a subsequently introduced security measure can hardly be noticed by outsiders.

It goes without saying that such a system can be used not only as a repair process, but also for the initial construction of technical masonry if the statics have been checked.

The subject matter of the present invention results not only from the subject matter of the individual patent claims, but also from the combination of the individual patent claims with one another.

All information and features disclosed in the documents, including the summary, in particular the spatial configuration shown in the drawings, could be claimed as being essential to the invention, insofar as they are new, individually or in combination, compared to the state of the art. The use of the terms “essential” or “according to the invention” or “essential to the invention” is subjective and does not imply that the features named in this way must necessarily be part of one or more patent claims.
In the following, the invention is explained in more detail with reference to drawings showing several possible embodiments. Further features and advantages of the invention that are essential to the invention emerge from the drawings and their description.

Figure 1 shows a carrier unit 1 with two belt plates 10 a, b, which are connected to one another via a web 9. The carrier unit 1 has a pointed end 16 in order to facilitate the introduction of the carrier unit into the substrate 7.

Approximately halfway up the carrier unit, three holding plates 8a, b, c are screwed to the carrier unit 1, the holding plates 8 projecting perpendicularly from the carrier unit 1 in the example shown here.
For this purpose, the belt plates have drilled holes 17 to which the retaining plates 8a and 8c can be mounted and screwed via a screw connection 15. The web 9 also has drilled holes to which the retaining plate 8b can be mounted and screwed.

On the individual holding plates 8a, b, c, movable spherical bodies 18 are arranged in a through opening 38, which spherical bodies 18 receive a peg 5 with a thread. The spherical body 18 is held by an upper holding plate 19 which is screwed to the holding plate 8. In addition, the spherical body 18 has a holding stub 20 which has an internal thread, by means of which a rotary movement applied to the holding stub 20 can be transmitted to the external thread of the peg 5. For the application of the rotary movement, the holding stub 20 has application surfaces distributed around the circumference for the application of a tool.

This arrangement is summarized below with the spherical body 18, the holding plate 8 and the screw connection 47 with the peg as a ball joint 6.

Figure 2 shows a to Figure 1 modified example, a flange plate 23 being screwed to the carrier unit 1 above the retaining plates 8. The flange plate 23 consists of two semicircular pieces 23 a and 23 b, which are joined together during assembly on the carrier unit 1 and form a closed disk. The flange plate has a large number of boreholes 14 distributed on the edge, which are used to screw a pipe element that is placed on the flange plate and has a flange plate of the same type.

The flange plate 23 itself is screwed to the carrier unit 1 via the screw connection 24.

Between the boreholes 14 there are threaded bores 7 for receiving adjusting screws, which can be screwed in from the underside of the flange plate in order to act on the flange plate 27 of an attached tubular element. An adjustment of the post or tubular element 12 with respect to the alignment of the longitudinal extension is thus possible.

Figure 3 Figure 13 shows a representation of the components from which the post support assembly is assembled. Thus, the belt plate 10a is shown with the drill holes 17 for attaching the retaining plates 8a, c, as well as the web 9 of the carrier unit 1, which has the drill holes 48 for attaching the retaining plate 8b. In addition to the carrier unit 1, the various components of the retaining plates and the flange plates are shown.

Starting from a circular surface, the holding plate 8b has a straight extension 58b, on the upper side of which the corner connection 52 is welded standing in a later processing step, the other end of which is welded to the plate 51. In a further processing step, one end of the corner connection 53 is welded to the underside of the projection 58b in an upright position, the other end of which is also welded to the plate 51. The corner connection 52, 53 thus form a diagonal connection between the holding plate 8, which are perpendicular to one another, and the plate 51.

As on the holding plate 58b, a corner connection 52 and a corner connection 54, which in turn are connected to a holding plate 51, are welded onto the holding plate 8a, c and their extension 58a, c.

The flange plate 23, which is present with the two halves 23a and 23b, has two parallel slots per half.

Four plates 55 are welded to the flange plate 23 per half, which laterally delimit the slots 56 along their longitudinal alignment. Thus, the slots 56 can receive the belts 10 a, b in sections and the flange plate 23 can be screwed to the belts 10 a, b via the plates 55. This is in Figure 4 shown, where Figure 4 one opposite Figure 1 easy shows modified embodiment of the support arrangement with two holding plates 8b which are attached to the front and rear of the web 9. In addition, in Figure 4 the corner connections 54 are also shown, which run diagonally between the plate 51 arranged perpendicular to one another and the underside of the holding plate 8. Such as the corner connections 52, which run diagonally between the plate 51 arranged perpendicular to one another and the top of the holding plate 8.

Figure 5 shows the top view of the carrier unit 1 to which the retaining plates 8 are screwed and the upper retaining plates 19 are screwed onto the lower retaining plates 8, with which the spherical body 18 can be clamped on the retaining plate 8.

Figure 6 shows the embodiment according to Figure 1 , wherein a mast 13 is additionally mounted on a carrier unit 1, whereby a post support structure is created. This mast 13 is solid and is screwed to the support unit 1 via the screw connection 25, the round mast being mounted between the two belts 10 a, b. The screw connection 25 is passed through a bent sheet metal 26 which, with its curved shape, rests on the outer circumference of the mast 13 and, after being screwed to the support unit 1, additionally stabilizes the mast.

Figure 7 shows the embodiment according to Figure 2 , wherein a tubular element 12 has been placed on the carrier unit 1. The tube element 12 has a flange plate 27 on its underside, which is placed on the preassembled flange plate 23 of the carrier unit 1 and screwed to it via the screw connection 28.

Figure 8 shows the erection and fixing of the post support arrangement of the carrier unit 1 in the subsurface 7. First, starting from the top edge 29 of the terrain, a hole 59 is dug until a predetermined depth is reached. The support unit 1 is driven with the tip 16 first into the base 49 of the hole or into the underlying base 7, until the holding plates 8 mounted on the support unit 1 rest on the base 49. The desired depth for setting up the carrier unit 1 is thus achieved. Then the Ground nails 5 are driven through the ball joints 6 of the retaining plates 8 into the substrate 7 below the bottom 49 of the hole 59. The support unit 1 is thus fixed in the subsurface 7 by the pegs 5, the pegs providing the necessary stabilization.

The hole 59 is then filled up again with pourable material up to the top surface 29, as shown in FIG Figure 9 you can see.

Figure 9 shows the side view of Figure 8 in the buried state, the retaining plates 8 now being located below the top edge 29 of the ground in the subsurface 7. According to the invention, the holding plates 8 are arranged outside the central longitudinal axis of the carrier unit 1. Is also in Figure 9 It can be seen that the end 16 of the carrier unit 1 is sharpened in order to facilitate the introduction of the carrier unit 1 into the substrate 7.

Figure 10 shows the top view of the carrier unit 1, which has the three retaining plates 8a, b and c, which extend perpendicularly, starting from the central longitudinal axis of the carrier unit 1, in three directions. In the holding plates 8, the ball joints 6 for aligning the pegs are arranged, which are composed of the spherical body 18, the holding stub 20 and the upper holding plate 19 in connection with the screw connection 38 in the holding plate 8.

Figure 11 shows the upper holding plate 19 and the lower holding plate 8 in a sectional view, the holding plate 19 having a passage opening 37 and the lower holding plate 8 having a passage opening 38.

Between the holding plates 8, 19 there is a gap 39 which, depending on the size of the inserted spherical body 18, can be of different sizes. Starting from the gap 39, the passage opening 37 tapers towards the outside in the upper holding plate 19. The passage opening 38 of the holding plate 8 also tapers outwards, starting from the gap 39.

The inner edges 41 of the access opening 37 of the upper holding plate 19 form an opening angle 43 to one another in the example shown here. The inner edges 42 of the access opening 38 of the lower holding plate 8 also form an opening angle 44 to one another.

This shape with the outwardly tapering through openings enables the inserted spherical body 18 to be held between the two retaining plates 8, 19 designed to fix the spherical body 18 so that it cannot fall out of the through openings 37, 38. Thus, the inner edges 41, 42 can also be designed to be curved or have a different geometric shape.

The gap 39 is also variable and can be made larger or smaller depending on the size of the spherical body 18. The two retaining plates 8, 19 are then held together by the screw connection 47, consisting of the screw 45 and the nut 46.

Such a screw connection of the individual holding plates to one another serves to fix the spherical body 18 in a desired position inside the holding plates 8, 19. For example, the spherical body 18 with its peg 5 can assume an angle deviating from the vertical direction in order to drive the peg obliquely into the ground or the ground 7.

With the ball joint 6, pegs 5 can thus be driven obliquely into the ground in a lower retaining plate 8 resting on the substrate 7, ie at an angle less than 90 ° with respect to the lower retaining plate 8. For this, the spherical body 18 remains movable between the retaining plates 8, 19 until the peg 5 has assumed the correct angle and after the alignment of the spherical body and the insertion of the peg 5 into the ground, the spherical body 18 is between the two retaining plates via the screw connection 47 Clamped in a secured position so that this angle is permanently set.

If it is necessary to retighten the peg 5 at a later point in time, the screw connection 47 is released so that the spherical body 18 can be rotated again. A rotary movement is then exerted on the spherical body 18 with a tool via the holding connector 20 and the peg 5 is driven upwards out of the subsurface 7 or downwards into the subsoil, depending on the direction of rotation.

Figure 12 shows a further embodiment of the present invention, wherein the inventive carrier unit 1 no longer has ear-shaped retaining plates 8, but at least one horizontally laid carrier unit 2. The carrier unit fulfills the function of the retaining plate, as is the case with the post support arrangement. Thus, this exemplary embodiment shows a wall support arrangement 50 as an example of a support arrangement using a decentralized holding position and support.
The use of such carrier units 2 also enables the entire arrangement to be fixed and stabilized outside the central longitudinal axis of the carrier unit 1.

The carrier unit 2 also has ball joints 6 with which the pegs 5 can be inserted into the ground 7 and secured in position. The carrier unit 2 and the further carrier units connected to it are also arranged below the top edge 29 of the terrain and form a flat foundation or an arrangement of pegs for a masonry support structure.
In the example shown after Figure 12 In addition to the horizontal support unit 2, which protrudes perpendicularly from the support unit 1 and runs parallel to the top edge 29 of the terrain, there is another support unit 32 which rests on the support unit 2 and is firmly screwed to it. The orientation of the carrier unit 32 is perpendicular to the longitudinal axis of the carrier unit 2 and serves to additionally absorb forces which are transmitted through the masonry via the carrier unit 1 to the carrier unit 2. The carrier unit 32 thus serves to provide additional support for the masonry 3.

The carrier unit 1 rests on the masonry 3 and is connected to it via a screw connection 30.

The carrier unit 2 is connected to the carrier unit 1 via a screw connection 60. For better force distribution, a corner connection 31 is also arranged in the connection area between the carrier unit 1 and the carrier unit 2 and is screwed to the carrier unit 1 via the screw connection 61. Alternatively, the carrier units can also be welded to one another and the corner connection to the carrier units

In the example shown here, the carrier unit 2 and 32 are designed as a double-T carrier, the ball joints 18 being located in corresponding pass-through openings in the belt 34 of the carrier unit 2 and in the belt 33 of the carrier unit 32.
The support units 2 and 32 thus form, together with the ball joint 6 and the peg 5, the underground peg arrangement.

Figure 13 shows the top view of Figure 12 with the carrier unit 1, which is connected to the masonry 3 via the screw connection 30 and supports it. The carrier unit 2 is screwed to the carrier unit 1 via the screw connection 8. For better illustration, the upper straps 33a, 34a of the support units 2, 32 are shown as transparent in order to better recognize the ball joints 6 located below.
In the example shown here after Figure 13 the carrier unit 2 has a number of ball joints 6 which are arranged parallel to one another and which the carrier unit 32 running perpendicular to the carrier unit 2 also has. The carrier unit 2 and the carrier unit 32 thus form a cross and are screwed to one another at the crossing point.

Figure 14 shows a top view of the carrier units 2, 32 wherein the belt 34a of the carrier unit 2 can be seen, which is narrower than the belt 34b of the carrier unit 2. The narrower belt provides access to the ball joints 6 connected to the belt 34b from above possible. Likewise, the carrier unit 32 has the belt 33a, which is also narrower compared to the Belt 33b is formed. These different widths of the belt also served to ensure that the ball joints 6, which are located in the belt 33, can be accessed from above in order to insert and align the pegs 5.

Figure 15 FIG. 4 shows the front view of the carrier arrangement according to FIG Figure 12 .

Figure 16 shows the screw connection of the carrier unit 2 to the carrier unit 32 in an enlarged view, it being evident that the belt 33a of the carrier unit 32 is narrower than the belt 33b. The alignment of the edges of the straps 33 a, b form a line 35 which is formed at an angle with respect to the corner connection 36 of the carrier unit 32. This is intended to make it clear that, due to the narrower belt 33 a, access to the ball joint 6 is possible, which is located on or in the belt 33 b.
