Description

Austrian Patent Office AT 507 990 B1 2011-02-15

Description: The invention relates to a connecting part for the aligned connection of adjacent double-bar or flat-bar or combined double-bar flat-bar mesh mats according to the preamble of claim 1.

Furthermore, the invention relates to connection arrangements for the aligned connection of adjacent double bar or flat bar or combined double bar flat bar lattice mats.

Finally, the invention relates to a fence of adjacent, aligned interconnected Doppelstab- or flat bar or combined double-rod flat bar lattice mats.

Lattice mats consist of approximately at right angles crossing longitudinal and transverse bars, the longitudinal bars on the transverse bars (or vice versa) rest and are welded in crossing points with them. The longitudinal and transverse bars usually have a round cross-section (so-called round bar lattice mats), but also square or rectangular cross-section is possible.

Double-rod lattice mats in the sense used here are those lattice mats in which the longitudinal bars between a lower layer and an upper layer are arranged in the same fleas opposite transverse bars for reinforcement in the rule. So there are two layers of crossbars. Cross bars and longitudinal bars can be of different material thickness and round, square or rectangular.

Flat bar lattice mats are those grid mats in which, instead of a front and rear cross bar, a single rectangular flat steel profile with openings for the passage of the longitudinal bars occurs. The front and rear cross bars are virtually summarized and form a flat flat bar.

In addition, there is a second type of flat bar lattice mats. In these, the flat bars are not penetrated in the middle of the longitudinal bars, but the flat bars are welded on one side only at the front or rear of the longitudinal bars. The invention described below is applicable to any type of flat bar lattice mats and therefore is intended to include both.

By combined double rod flat bar lattice mats are meant here those having both double bars and flat bars, e.g. For example, the uppermost and the lowermost transverse bar may be provided as a flat bar, while the intermediate transverse bars are designed as double bars.

In general, the double rod or flat bar or combined double-rod flat bar lattice mats are arranged so that the cross bars or the flat bars in the assembled state approximately horizontally, the longitudinal bars come to lie approximately vertically, but in principle is also a reverse Arrangement (cross bars or flat bars about vertical, longitudinal bars approximately horizontally) possible.

A the preamble features of claim 1 exhibiting connection part and a corresponding connection arrangement and a corresponding fence is known from DE 25 34 767 A1.

The there specifically disclosed for double-rod lattice mats, but also in Flachstaboder combined double-rod flat bar lattice mats usable connection part is a substantially flat plate, are bent in the two parallel opposite edges to the same side, so that an elongated flat U-shaped basic form arises. The inner foot width of this U-shaped basic shape is a multiple of the diameter of a transverse bar. The bends are designed so that their edges protrude beyond the direction in the direction of bending plate surface by a the diameter of the gripped bar below the amount. The U-thighs are therefore of lesser fleas than 1/18 Austrian Patent Office AT 507 990 B1 2011-02-15 a grid bar diameter. In the middle region, the bends are provided with recesses which do not reach all the way to the plate surface, in which the end longitudinal bars of the double-bar lattice mats to be joined are accommodated. The recesses are formed as at least material-removing cutouts or cutouts. Perpendicular to come along one of the two bends to lie on the inside of the end pieces of the cross bars of the connecting double-rod mesh mats. The other, opposite bend presses with the edge of the recess on the two end-longitudinal bars of the connecting double-rod mesh mats. Characterized in that in the one turn the transverse bar ends of the double-rod grid meshes to be connected, but in the other, no such are received, but the bends are free inside, the connecting part is slightly tilted relative to the plane formed by the double-rod mesh mats , On the other side of the double-rod grid mats, an identical second connecting part is provided, so that the double-rod grid mats are clamped between the two connecting parts.

Center of the connecting part a hole for the passage of a screw is provided, which serves on the one hand for bracing the components involved, on the other hand for attachment to a post.

Under heavy vertical loading of a fence constructed with these known mounting arrangements, such as e.g. When climbing or over climbing occurs, there is a risk that the double-rod mesh mats slip down - especially with decreasing bias of the screw over time. In this case, the connection arrangement can scrape along with the surfaces of the recesses on the end longitudinal bars and destroy the weather surface protection.

It is therefore an object of the invention to avoid this disadvantage and to provide a connecting part and a connection assembly and a fence constructed therewith, in which slipping of the grid mats is excluded under vertical load.

This object is achieved by a the features of claim 1 having connec tion part and connecting arrangements with the features of claims 7 and 10, and of a fence according to the features of claim 21.

The invention makes use of the knowledge that a vertical displacement of fence elements can be avoided if the end pieces of the transverse bars or flat bars of adjacent grid mats are positively enclosed in the vertical direction. This is achieved in that the inner foot width of the U-shaped basic shape of the connecting part corresponds to the thickness of the encompassed end pieces of the transverse bars or flat bars, so that the connecting part comprises the transverse bar ends or flat bar ends in a form-fitting manner.

To perform the recesses as integrally formed bends from the U-legs, results in a larger base height, on which rest the end longitudinal bars, as in a production of the recesses by material removal (punching or milling) would be the case, and thereby contributes to Stability of the construction.

Advantageously, a central hole may be provided for the passage of the tightening element in the bottom of the U-shaped basic shape of the connecting part.

Alternatively, the connection part can also be encompassed by the tightening element, e.g. if a hook screw is used as a tightening element. Then it is advantageous if recesses are provided in the bends, in which engages the tightening element.

The bottom of the U-shaped basic shape of a connecting part may alternatively be round or square.

Advantageously, it is provided as a material for the connecting part according to the invention stainless steel or galvanized or chromium-plated structural steel or aluminum or plastic.

The connection of adjacent double rod or flat bar or combined double rod bar flat bar mesh mats can be done with a connection arrangement using two (identical) inventive connecting parts, which are clamped together by a tightening element under clamping of the adjacent grid mats (claim 7).

In this case, the connection of two grid mats can be made quasi flying without attachment to a post. The second connecting part then serves as an abutment. The attachment of the fence elements to a post can then be done at any other location, regardless of the respective end of a grid mat. This allows greater freedom in positioning the posts, depending on e.g. Terrain features.

Alternatively, when using two connecting parts but also a simultaneous attachment may be provided on a post.

Alternatively to the described connection by means of two connecting parts may be provided to use a connection arrangement with only one connecting part according to the invention. In this case, a simultaneous attachment to a post is required, since this then serves as an abutment (claim 10).

It can be provided in double-rod or combined double-rod flat bar mats, that are covered by the connecting part, the end pieces of the front cross bars of the adjacent grid mats, which are the cross bars which are off the post, i. the ones lying away from the post. For flat bar or combined double bar flat bar lattice mats, these are the front portions of the flat bars of adjacent lattice mats remote from the post.

It may also be provided to provide the connection of two adjacent grid mats independently of the crossbar or flat bar end pieces, at locations where there is no crossbar or flat bar. Then the clamping of the grid mats takes place only over the extending in the bends in the U-legs end longitudinal bars. The elongated U-basic shape remains free. This connection method can be provided both in a connecting arrangement having only one connecting part, or in a connection arrangement with two connecting parts and is especially advantageous where additional stiffening is desired or where, for another reason (eg height offset of two grid mats not according to the grid) it it is not possible to make an attachment to the nearest cross bar or flat bar.

The tightening element may be a threaded through the hole of a connecting part or through the holes of both connecting parts. In this case, the mating thread can be cut during assembly of this itself in the abutment (opposite connecting part or post) or it can be provided a cap nut or a conical nut or a conventional through-hex nut.

As a tightening element and a rivet can be used.

If it is provided to use as a tightening element a hook screw, this surrounds the connecting part or the connecting parts in the transverse direction. If the connecting part in the bends provided with recesses (not mandatory), the hook screw engages in these recesses. The mating thread to the hook screw can be formed in a cap nut or a conical nut or a conventional through-hex nut. The use of the self-tapping technique, as possible with a normal threaded screw, is eliminated in a hook screw of course.

To adapt to different post shapes (eg, round, square), to adapt different distances between grid mat parts and posts (eg in the variant in which the clamping on the post only via the clamped by the bends in the U-legs end longitudinal bars takes place), as well as generally for insulation and damping adapted spacers can be used.

These may be made of plastic, hard rubber or other elastic material.

A special shape of a spacer may have a groove for the storage of a transverse bar or flat bar end and a central hole for the passage of a tightening element.

Furthermore, it can be provided to provide connecting parts for the protection of materials in the U-shape with a thin damping and / or insulating insert, such as rubberized textile, rubber, Teflon, or other plastic.

A fence of adjacent aligned double bar or flat bar or combined double bar flat bar lattice mats is assembled with connection assemblies using one or more fasteners of the invention (claim 21).

The lattice mats, depending on the terrain conditions, height or offset in height can be mounted approximately horizontally. Corresponds to the height offset one or more formed by the position of the cross bars or flat bars pitch, so a connection is possible, in which the end pieces of the transverse bars or flat bars of the two grid mats are accommodated in one or in the two connecting parts according to the invention. The connection can then take place both with the inclusion of a post and on the fly.

If the height offset does not correspond to the grid dimension, then a connection of two grid mats, although with reduced strength, is in principle possible such that the clamping takes place only via the end longitudinal bars clamped in the U-legs by means of the bends and the elongate U Basic shape remains free. It is also possible to make a connection of two grid mats so that on one side of the connecting part an end piece of a transverse bar of a grid mat is stored, while on the other side of the connecting part, the U-basic shape remains free and a clamping only on the in the Bend lying end longitudinal bar of the other grid mat is done.

Also possible is a one-sided end attachment of a grid mat to a post without connection to the second grid mat (e.g., the top or bottom node in a height-offset mounting). It can remain empty in this case, the U-shaped basic shape on the free side of the connecting part. Then the connecting part tilts slightly. But it can also be inserted on the free side of a small end piece of a transverse bar in the U-shaped basic shape. Then the connection part is straight.

These named connection ways can be provided both in a connection arrangement having only one connection part, or in a connection arrangement with two connection parts.

As an alternative to horizontal mounting an oblique mounting, adapted to a terrain slope is possible. In this case, the attachment of the grid mats to posts separately, regardless of the (then flying) connection of two grid mats must be done together.

Further features, details and advantages of the invention will become apparent from the following description of an embodiment with the aid of a drawing.

Fig. 6 is a perspective view of a part of a fence with connec tion arrangements using only one connecting part according to the invention connected lattice mats; while attached to a post; 7 a, b, c: side views of the connection and fastening arrangement shown in Figure 6; Fig. 8a: a side view of an exemplary fastening and Verbindungsan order with a spacer; Fig. 9b; Fig. 9b; Fig. 10b; Fig. 11 is a perspective view of an example of a spacer, a plan view of a connector insert; a connecting part with built-in insert in perspective view; a view of a mounted with height offset in pitch grid fence; a view of a height offset mounted fence wherein the height offset does not correspond to the grid; Fig. 12: a view of an obliquely mounted fence in continuous laying. Fig. 1 is a perspective cutaway view of a part of a fence 1 composed of aligned combined double-rod flat bar mesh mats 2,2a. The mesh mats 2, 2a consist of mutually at right angles and welded together longitudinal bars 3 and transverse bars 4, 4a, which continue beyond the illustration in FIG. 1 also to one side and upwards, wherein for reinforcement in the picture above and center two layers of transverse bars 4, 4a are provided, so that the longitudinal bars 3 are arranged between a lower layer and an upper layer of the same height opposite cross bars 4,4a. Cross bars 4, 4a and longitudinal bars 3 may be of different material thickness. You can, as shown here, have round cross-section, but also (not shown here) square or rectangular cross-section and hybrids are possible. At the bottom of the picture, the transverse bars 4, 4a are replaced by flat bars 27, in which a front transverse bar 4 and a rear transverse bar 4a are to a certain extent combined to form a flat steel profile 27 with openings 28 for the longitudinal bars 3.

In general, the grid mats are arranged 2,2a so that the transverse bars 4, 4a and the flat bars 27 approximately horizontally (horizontally), the longitudinal bars 3 come to lie approximately vertically, as shown in, in all figures. However, in principle, a reverse, not shown here arrangement (cross bars 4, 4a or flat bars 27 approximately vertically, longitudinal bars 3 approximately horizontally) possible, which is e.g. This can be the case with high height ball catchers.

The lateral boundary of each grid mat 2,2a is formed by an end longitudinal bar 5. The cross bars 4,4a terminate in nodes 6 resting on the end longitudinal bars 5. The flat bars 27 also terminate where they meet the end longitudinal bars 5. Respective mutually facing end longitudinal bars 5 of two grid mats 2,2a are arranged at a distance parallel to each other.

The two grid mats 2, 2a are interconnected by means of connecting arrangements 9, which here comprise two connecting parts 8. These connection arrangements 9 can optionally be provided at each node 6, or omitting one or more nodes 6, as illustrated in FIG. 1 using the example of the central node 6, only at a few selected nodes 6, depending on the strength requirement.

Hereinafter, various embodiments of a connecting part 8 according to the invention and a connection assembly 9 using in particular the Austrian Patent Office AT 507 990 B1 2011-02-15

Figures 2 a, and 2b, and 3 a-d described in more detail.

In this case and in the other figures, not all reference numerals in all the following figures are repeated for the sake of clarity. Only new, not yet mentioned or important in the context important reference numerals are drawn. Nevertheless, the person skilled in the art is able to transfer the reference numbers not shown in a meaningful way.

The connecting part 8 is of elongated U-shaped basic shape, with two U-legs 14 and a round Fußgrund 31. Alternatively, as can be seen from Figure 3 d, the Fußgrund 31 also be formed angular, which is for mounting with a Flat bar 27 may be advantageous. However, this is not mandatory, as shown in FIG. 2b, in which a flat bar 27 is combined with a connecting part 8 with a round bottom 31.

The foot width B, ie the distance between the two U-legs 14 from one another corresponds to the thickness D of the embedded transverse bar 4, 4a or flat bar 27, i. the foot width B is slightly larger than the thickness D, so that the cross bar 4, 4a and the flat bar 27 fit with a small mounting clearance between the U-legs 14.

Each connecting part 8 has at each U-leg 14 has a recess 10 for receiving the end longitudinal bars 5 of the grid mats 2, 2a to be connected. The recesses 10 are designed as integrally formed bends 11 from the respective U-leg 14. This obviously results in a greater base height on which the end longitudinal bars 5 rest than when the recesses 10, e.g. punched out.

The bends 11 have a Ausbiegungslänge L on. This must be at least sized so that they can accommodate both end longitudinal bars 5 and the tightening element 13 with a certain assembly game. This situation is shown in FIGS. 2a and 2b.

But it is also possible to make the Ausbiegungslänge L much larger, as shown in Figures 3b and c and in the assembled state, for example in Figure 6 at the upper and lower attachment point. A larger Ausbiegungslänge L results in the assembly a greater flexibility with respect to the distance of the end longitudinal bars 5 of the two grid mats 2, 2a from each other. At the ends 32 of the bends 11 edges 33 are formed in the U-legs 14. (Figure 2b). At these edges 33, the end rods 5 come in a lattice mats 2, 2 a pulling apart movement to the plant. The edges 33 thus limit a pulling apart of adjacent grid mats 2, 2 a and prevent the end longitudinal bars 5 from slipping out of the connection arrangements 9.

The leg height S of the connecting part 8 is to be dimensioned so that when a connection consists of two connecting parts 8 9 is provided (Fig. 2a), in the assembled state, the two leg ends 34 do not touch, but at the same time the leg height S is greater as the thickness D of a round bar. For the case illustrated here by way of example of the combination of a round transverse bar 4, 4a with a connecting part 8 with a rounded bottom 31, the design rule is that the leg height (S) must be greater than the thickness (D) of the engaged transverse bar (4, 4a). but smaller than the sum of the thickness (D) and half the diameter (H) of the end longitudinal bars (5, 5a).

For other combinations, the person skilled in the art is able to deduce the designation correctly. It must be considered that when combining a flat bar 27 with a round footing 31, the flat bar outer edge 29 (Fig.2b) of course can not reach all the way to the bottom, and the remaining measure must be taken into account.

In the bottom 31 of the connecting part 8 in Fig. 3a, b, d, a central hole 12 is provided for the passage of a tightening element 13. The tightening element 13 may e.g. a threaded screw 16 (Figure 5a) of any kind. That with approximately trained Fußgrund 31 in the mounted state of the screw head or the mother only punctual material contact with the outer bottom of the recess 15, ie with the edge of the hole 12 has proved not to be disadvantageous, it is nevertheless a high strength of the compound reached. As a tightening element 13 can also be a self-tapping screw, in question, which cuts its thread during assembly itself in the abutment. As an abutment, a post 18 may be provided. When flying installation (Fig. 1) and the second connecting part 8 represent the abutment, of course, then the size of the hole 12 in the abutment to select correspondingly smaller than a through-bolt.

Also, a rivet (not illustrated here) can serve as a tightening element 13.

Furthermore, a hook screw 22 (Fig. 4, 5c) may be provided as a tightening element 13. In this case, the hook bolt 22 surrounds with its Hakenrundung depending on the or the connecting part (s) 8 transversely, as shown in Figures 4 and 5c for an existing two connecting parts 8 connecting assembly 9 and as in Figures 6 and 7b and c for a connection arrangement 9 is shown, which has only one connecting part 8.

If such a hook screw 22 is provided as a tightening element 13, then for an immovable seat, as shown in Figure 3 c, the bends 11 of the or the Ver-binding part (s) 8 are provided with recesses 30, in which the hook screw 22 engages during assembly. However, this is not absolutely necessary, as the installation examples in FIGS. 4 to 8 show.

The connecting parts 8 can optionally be produced both with holes 12 and with recesses 30, or even with only one of the two.

As a material for the connecting parts 8 stainless steel, galvanized or chromium-plated steel, aluminum or other metals, coated or uncoated, can be used, it being understood that coatings, chrome plating, etc. take place only after forming. But the connecting parts 8 can also be made of plastic by plastic injection molding.

While FIG. 1 and in FIG. 11 to be explained later illustrate a flying, ie postless, connection of two grid mats 2, 2 a (also referred to as "endless laying"), FIG. 4 shows a connection of two grid mats 2, 2 a below simultaneous attachment to a post 18. By way of example, in Figure 4 in perspective view different attachment and connection options, in the accompanying figures 5a to c, the respective connection points shown in a partially sectioned side view. Figure 5 a belongs to the upper, Figure 5b to the middle, Figure 5c to the lower attachment point. All have in common that the connection assemblies 9 are each designed with two connecting parts 8.

In the upper attachment point comprises a connection assembly 9, the end pieces 7 of two round-double-bar mesh mats 2,2a with simultaneous attachment to a post 18 with a post 18 through a hole 19 by cross threaded screw 16, wherein a conical nut 17 is provided as a mating thread , Cone nuts tighten themselves in the hole 12 of the connecting part 8 and are, since having smooth surfaces, secured against wanton loosening.

The middle connection point in Fig. 4 (corresponding to FIG. 5b) fixes only the two end longitudinal bars 5 with simultaneous attachment to the post 18 with a threaded screw 16 with cap nut 24. Since the connection does not take place in a node 6, remain elongated U-basic shapes in the connecting parts 8 free. The clamping of the grid mats 2, 2a is carried out only on the means of the bends 11 in the U-legs 14 clamped end longitudinal bars 5. This type of attachment and connection, of course, can not have the stability and strength, such as a connection and fastening in nodes 6th However, it is conceivable as a supplement to increased requirements or even in the case of horizontally offset, but not in the grid possible assembly of grid mats 2,2a. This will be discussed in detail later.

The connection and attachment in the lower point in Figure 4 (corresponding to Fig. 5c) by means of a hook screw 22, which surrounds the two connecting parts 8 with the embedded end pieces 7 of the cross bars 4,4a. The hook screw 22 passes through the 7/18 Austrian Patent Office AT 507 990 B1 2011-02-15

Bore 19 in the post 18 and is tightened with a passage hex nut 25, wherein the connecting parts 8 and grid mats are clamped 2,2 a.

Alternatively to a hook screw can - not shown here in the drawing - also a U-shaped curved rod with threads are used at its two ends. There are then two in an appropriate distance to be positioned holes 19 in the post required. This mounting variant has again increased stability and strength.

Analogously to the illustration in FIGS. 4 and 5, fastening and connection possibilities are disclosed in FIGS. 6 and 7 described below, which have connection arrangements 9 with only one connecting part 8.

In the upper connection point in Figure 6 (corresponding side view Figure 7a), the end pieces 7 of the front, remote from the post 18 transverse rods are received by the connecting part 8. (In the case of flat bars 27 instead of transverse bars 4, 4a, these are analogously only the front parts of the flat bars 27, which are remote from the post. The rear cross bars 4a lie directly on the post 18. The attachment to the post 18 is carried out with an already described threaded screw 16 with conical nut 17. As can be seen, it is the connecting part 8 with such a large Ausbiegungslänge L of the deflection 11. Nevertheless, the end longitudinal bars are not at the edges 33 of Bends 11, but are closer together. This is due to this exemplary representation, that the connecting part 8 in the middle attachment point is such with only small Ausbiegungslänge L, and the removal of the end longitudinal bars 5 of the two grid mats 2, 2a by the abutment against the edges 33 of this middle connecting part eighth is determined. The combination of lattice mats 2,2a with combinations of connecting parts 8 different Ausbiegungslängen L, able to compensate for any deviations or inclinations of lattice mats 2,2a or individual bars.

To compensate for the distance and thus the end longitudinal bars 5 when tightening the hook screw 22 does not bend, is a spacer 21 between posts 18 and Inserted end longitudinal bars 5, which corresponds in its thickness to the upper transverse bar 4a.

The connection and attachment in the lower attachment point in Fig. 6, (corresponding to Figure 7c) by means of a connecting part 8 with large Ausbiegungslänge L using a hook screw 22nd

Spacers 21 can be further adapted for adaptation to e.g. different post shapes (round, square, etc.) are used in various places where necessary, and are to be designed according to their purpose, which is within the skill of the art. Spacers 21 may be e.g. be elastic or non-deformable, made of plastic, hard rubber or aluminum. Spacers 21 may have a central hole 15 (FIG. 8 b) for the passage of a tightening element 13 and be provided with a groove 26. The latter enables an insulated or damped mounting of the grid mats 2, 2 a on posts 18, illustrated by way of example with hook screw 22 in FIG. 8 a, with simultaneous connection of the grid mats 2, 2 a in nodes 6. by abutment of metallic parts at e.g. vibrating mesh mats 2,2a caused noises to be avoided.

A similar damping effect can be achieved if in the U-shape of a connecting part 8, a thin insert 20 is inserted from damping or insulating material, as shown in Fig. 9a and b. This insert 20 may for example be made of rubberized or ungummed textile, Teflon or other plastic or rubber.

In order to adapt a fence 1 to terrain properties, the grid mats 2, 2 a can be mounted in various ways and fastened to posts 18.

In the simplest case, in which the mounting of the grid mats 2,2a takes place approximately horizontally and at the same height, a laying with simultaneous attachment to a post 18 can take place, as shown in FIGS. 4 and 6. In the case in which a horizontal, but offset in height mounting of the mesh mats 2,2a is required for leveling in slightly sloping terrain, and the height offset corresponds to a grid, is a fence assembly with simultaneous attachment of the grid mats 2, 2a on a post 18 as shown in Fig. 10 possible.

Corresponds to the height offset no grid, so mounting as shown in Figure 11 can be done: On the one hand, only a grid mat 2, 2a with a connecting part 8 on the post 18 is fixed in a node 6 (Figure 11 above). In this case, it is possible for the U-shaped basic shape to remain empty on the free, right-hand side of the connecting part 8. Then the connecting part 8 tilts slightly, but this does not detract from the strength and stability. Or it can be inserted on the free side a small separate separate end piece of a transverse bar 4, 4a in a sense as a dummy in the U-shaped basic shape. Then comes the connecting part 8 just to lie.

In addition, at several points an attachment can be made only by clamping the end longitudinal bars 5, as detailed in the description of Figures 4 and 6. Two such joints are inserted in Figure 11 in the middle. Finally, at a node 6 of a grid mat 2, 2a, at the height of an end longitudinal bar 5 of the adjacent grid mat 2, 2a is present (bottom of Fig. 11), the attachment of a grid mat 2, 2a in the node, the other Lattice mat 2, 2a done only by clamping the end longitudinal bar 5. Due to its squat U-shape, the connecting part 8 is so strong that it is not deformed in such a one-sided load and thus able to make a stable connection.

For more sloping terrain, in which a horizontal, height-offset mounting of the mesh mats 2,2a for terrain adjustment would not be sufficient, because then, for. the spaces between the grid mat base and the ground surface on one side of the grid mats 2,2a would be too large, an oblique, the terrain slope adapted assembly of the grid mats and the whole fence 2 2.2a 1 will be required.

In this case, as shown in Fig. 12, with the connection assemblies 9, only the mesh mats 2,2a themselves are connected together, while the attachment to posts 18 is independent of the position of the connection assemblies 9 by fasteners 23 e.g. in the form of the cross bars 4, 4a encompassing hook bolts 22 or U-shaped bent rods with threads at both ends, takes place.

The attachment of the connected mesh mats 2, 2 a to posts 18, regardless of the position of the connectors 8, as shown in Figure 12 by the example of the oblique mounting of a fence 1, is commonly referred to as " endless laying " referred to and can also be done with horizontally mounted fence 1 with or without height offset. This type of independent attachment to posts 18 or connection of the grid mats 2,2a together has the inherent advantage that the posts 18 at a distance from each other need not be positioned exactly what is sometimes difficult to do in the field.
