Description

The present invention relates to a scaffolding comprising at least one scaffolding field having a first post and a second post spaced from the first post, wherein retaining wires extend between the posts.In the prior art, there are a wide variety of variants of ranking stands. It is advantageous, in particular for hobbygarters, to be able to buy a construction kit for a scaffolding, in which all scaffolding components are already contained, it then being possible for the scaffolding to be constructed quickly with the desired properties. The construction sets for scaffolding available on the market have fixed dimensions, in particular with regard to the width of the planting fields located between the posts, with which the customer must be located. Thus, for example, the kit for a scaffolding described in the publication EP 0 386 402 A1 has scaffolding fields in the form of prefabricated half grids with certain widths, wherein free wire ends of these half grids are connected by means of rod-shaped coupling members during the construction of the scaffolding.From the publication EP 1 928 224 B1 a ranking framework for wine is known which is relatively variable with respect to the width of the planting fields. The scaffolding has a plurality of posts arranged in a row and anchored in a ground, in front of and behind which a retaining wire runs in each case. The posts have a C-shaped cross section. As a result, the posts have a longitudinal slot running from top to bottom, in each of which a sliding device is located. At a front side of the sliding device there is a respective wire holder which has the shape of a U placed on the head. Holes are formed in the two ends of the wire holders, respectively, through which the holding wires are guided, respectively. At an upper side of the slider, an upper pulley assembly is disposed. The underside of the slider is connected to a spring which is connected to a lower pulley assembly. A pulley wire extending from a winch passes over the pulley assemblies to form a pulley block assembly. By means of this pulley block arrangement, the height of the wire holder and thus the height of the holding wires can be adapted to the size of a plant. In this case, the pulley wires provided in each post are connected to a synchronization wire connecting the posts at the bottom, so that the respective pulley block arrangements can be actuated simultaneously. A blocking wire runs between the holding wires and the synchronizing wire, to which the respective wine rack is fastened, while the drives are fastened to the holding wires. The locking wire is held on hooks provided on the posts.The document EP 1 928 224 B1 has the disadvantage that it has only a low rigidity.It is therefore the object of the present invention to provide a simple-to-construct scaffolding which has a high variability with respect to the dimensions of its plant fields and is nevertheless highly stable.This object is achieved by a scaffolding comprising at least one scaffolding field with a first post and a second post spaced apart from the first post, wherein retaining wires extend between the posts, wherein the posts are formed as Z profiles, wherein a first clamp is mounted on parallel rails of the first post and a second clamp is mounted on parallel rails of the second post, a first profile clamp aligned with the second post is pivotably mounted on the first clamp, wherein a first end of a transverse connector formed as a Z profile is inserted into the first profile clamp, and a second profile clamp aligned with the first post is pivotably mounted on the second clamp, wherein a second end of the transverse connector is inserted into the second profile clamp.In the case of the inventive scaffolding, the posts can be introduced into a ground at intervals suitable for the respective user. These distances determine a width of the planting field to be formed by the user. In this case, the posts can be anchored so deeply in the ground that the posts are stable. By means of the clamps and the profile clamps mounted thereon, at least one transverse connector stabilizing the scaffolding can be mounted between adjacent posts.In this case, the clamps can be provided on adjacent posts at different or at the same heights, so that the respective transverse connector can be aligned obliquely or horizontally.As a result of the pivotability of the profile clamps, these can be aligned in the direction of the respectively adjacent post such that the transverse connector can be suitably inserted with its two ends into the profile clamps to be respectively connected. In this case, the transverse connector, because it is designed as a Z-profile, can be easily inserted into the profile terminals respectively opposite the two ends of the transverse connector. By means of the two parallel profiled rails of the transverse connector which are oriented in opposite directions, it is securely held in the two profiled clamps.Since the height of the respective clamps can be variably adjusted on the posts, these can be fixed at such heights that the respective cross connector fits between the profile clamps. That is, depending on the selected distance between the posts, the angle at which the cross connector extends between posts will change. Independently of this, the transverse connector in each case results in a high stability of the scaffolding.The inventive scaffolding has the advantage that it is constructed with few handles.Insofar as the inventive scaffolding has at least two scaffolding fields arranged in series and thus at least three posts, it is advantageous if the second clamp mounted on the second post is mounted at a second height different from the first height of the first clamp mounted on the first post.If the inventive scaffolding has exactly two scaffolding fields arranged next to one another, it has proven to be practical if the first post forms a central post and two profile clamps are mounted on the first clamp mounted on the first post, which are oriented in different directions, i.e. in the direction of the posts respectively adjacent to the first post on both sides.In a preferred embodiment of the inventive scaffolding, at least one first hook is arranged on an outer side of at least one of the parallel profiled rails of the first post, to which hook a first end of a first wire is fastened in each case, at least one second hook is arranged on an outer side of at least one of the parallel profiled rails of the second post, to which hook a first end of a second retaining wire is fastened in each case, and a second end of the first retaining wire is connected to a second end of the second retaining wire by a wire tensioner.The wire tensioner tautens the first and second holding wires and can be re-tensioned at any time if necessary. The height of the hooks determines the height of the respective wire path running in the longitudinal direction of the scaffolding. Preferably, for this purpose, a plurality of hooks spaced apart from one another in height are formed on the posts. Thus, the heights of the retaining wires themselves can be selected, expanded or omitted by a user of the scaffolding according to the invention, which makes the scaffolding even more universal.It has proven advantageous if the first holding wire and the second holding wire are each twisted with themselves for their fastening to the respective post and optionally to the wire tensioner.In this embodiment of the invention, the respective wire is inserted into one of the hooks provided on the post and wound around the respective post with a wire length excess. The respective excess wire length is then wound several times around the wire section of the wire running in the longitudinal direction between the posts. As a result, the wire holds firmly on the post without the need for additional auxiliary means.In a standard version of the inventive scaffolding, the scaffolding has at least two scaffolding fields, wherein the transverse connectors mounted in a first of the scaffolding fields and in a last of the scaffolding fields are mounted in mutually opposite oblique alignment.Further embodiments of the inventive ranking framework can also have more than two framework fields. Then, preferably between the first and the last of the scaffolding fields, at least one further scaffolding field with wires running between the posts is arranged, without transverse connector, but with additional profile clamp.It is also possible in the case of the inventive scaffolding to mount its scaffolding fields via corners.A preferred embodiment of the inventive scaffolding will be explained in more detail below with reference to figures, wherein FIGS. 1 to 13 show different stages of the construction of a scaffolding 1 with two scaffolding fields 2, 3 shown by way of example. FIG. 14 shows an embodiment of the inventive scaffolding 1 with three scaffolding fields 2, 20, 3. FIG. 15 shows an embodiment of the inventive scaffolding 1 with a scaffolding field 2. FIG. 16 shows an embodiment of the inventive scaffolding 1 with two corner-arranged two-part scaffolding fields 2, 3, 3', 2'. FIG. 17 shows an embodiment of the inventive scaffolding 1 with two one-piece scaffolding fields 2, 2' arranged over corners.FIG. 1 shows schematically in a side view posts 4, 5 set up at a distance a from one another. For example, the distance a is 2 m. Each of the posts 4, 5 is designed as a Z-profile. Thus, each of the posts 4, 5 has two profile rails 41 spaced apart from one another by an obliquely running intermediate rail 42 and running parallel to one another.Furthermore, each of the posts 4, 5 has a plurality of hooks 6, 6' on at least one of its outer sides of the profile rails 41 which are arranged at different heights at a distance from one another. The hooks 6, 6' can be opened in different orientations.As can be seen schematically in FIG. 2, the posts 4, 5 are each anchored in a floor 7. An end region 43 of the respective post 4, 5 anchored in the floor 7 is preferably designed without hooks. For example, the respective post 4, 5 is driven into the ground 7 by a proposal hammer and a driving aid 50 cm.Thereafter, as shown schematically in FIG. 3, a respective clip 8, 8' is fastened to the posts 4, 5. As can be seen schematically in FIG. 13, a first clip 8 fastened to the first post 4 is located at a different height h 1 than a second clip 8' fastened to the second post 5. The respective clamp 8, 8' has in each case two clamp parts 81, 82, which are each placed on the profile rails 41 of the post 4, 5 and are or are connected to one another at their respective mutually opposite clamp surfaces 83, 84 projecting on both sides by means of screws 85 and nuts 86 in such a way that the clamp 8, 8' surrounds the post 4, 5.As can be seen in FIG. 4, a connecting piece 93 of a profile clamp 9, 9' is screwed between the clamp surfaces 83, 44 on at least one side of the respective clamp 8, 8'. The respective profile clamp 9, 9' has two clamp arms 91, 92 spread apart from the connecting piece 93. The clamping arms 91, 92 each project in the direction of the respectively adjacent post 4, 5.The respective profile clamp 9, 9' can be pivoted on the clamp 8, 8' and thereby be oriented in the direction of one end of a transverse connector 10, 10'.One end of the transverse connector 10, 10' designed as a Z-profile is clamped into the respective profile clamp 9, 9'. This can be seen in FIG. 5. In this case, the intermediate rail 42 of the respective Z profile is received between the clamping arms 91, 92. The profile rails of the respective transverse tie 10, 10' each cover the lateral opening region of the respective profile clamp 9, 9'.As a result, the construction shown schematically in Fig. 6 is obtained, in which the posts 4, 5 are cross-connected by the cross-connector 10 or 10', respectively.In order to construct a scaffolding 1 with two scaffolding fields 2, 3, the above-described procedure is then repeated on the other side of the second post 5, thereby producing the construction shown schematically in Figure 7.FIG. 8 schematically shows how the post 5 is wrapped around by a second retaining wire 12. The second retaining wire 12 is inserted into the hook 6' formed on the post 5.FIG. 9 schematically shows how the second support wire 12 is fastened to the second post 5. For this purpose, a first end of the retaining wire 12 wound around the post is wound, i.e. twisted with itself, multiple times, for example with five to eight revolutions, around a wire section of the second retaining wire 12 leading away from the post 5. In the same way, a first retaining wire 11 is fastened to the first post 4 at the same height as to the second post 5.The two second ends of the holding wires 11, 12 are then fed, as is schematically shown in FIGS. 10 and 11, to a wire tensioner 13. A second end 11' of the first holding wire 11 is guided through a transverse bore 132 formed in a holding arm 131 of the wire tensioner 13, wherein the first holding wire 11 is then twisted with itself.A second end 12' of the second retaining wire 12 is first passed through a longitudinal bore 133 of the wire tensioner 13 and then through a through nut 134 of the wire tensioner 13. The through nut 134 is a component of a clamping thread 135 that can be rotated from the outside. As shown schematically in Figure 12, by twisting the tension thread 135, the second end 12' of the second retaining wire 12 is wound around the through nut 134. In this case, both holding wires 11, 12 are simultaneously tensioned. The twisting can be effected, for example, with the aid of a jaw key.In this way, holding wires 11, 12 can be mounted between posts 4, 5 at different heights. A finished scaffolding 1 having two scaffolding fields 2, 3 can be seen in FIG. 13.In the case of the scaffolding 1 shown in FIG. 13, which in the embodiment shown is designed as a two-field scaffolding, two profiled clamps 9, 9" are mounted on the clamp 8 mounted on the first post 4. In this case, the profile clamp 9 is oriented in the direction of the second post 5 located on a first side of the first post 4, while the profile clamp 9" is oriented in the direction of the post 5' located on the other, second side of the first post 4.The inventive scaffolding can be extended, as is shown schematically in FIG. 14, by at least one further scaffolding field 20 arranged between the scaffolding fields 2, 3. This further scaffolding field 20 then has no transverse connectors 10, 10', but holding wires 11, 12 tensioned between posts 4, 4.In the variant of the scaffolding 1 illustrated in FIG. 15, which is configured as a single-panel scaffolding in the embodiment shown, the transverse connector 10 is arranged horizontally between the two posts 4, 5. In the embodiment shown, the cross connector 10 connects the two upper ends of the posts 4, 5. the cross connector 10 is held on the post 4 by the first profile clamp 9 fixed to the first bracket 8, while it is held on the post 5 by the second profile clamp 9' fixed to the second bracket 8'.The corner variant of the scaffolding 1 shown in FIG. 16 is composed of two corner-arranged two-panel scaffoldings, each of which is constructed as in FIG. 13, to which reference is hereby made.The corner variant of the scaffolding 1 shown in FIG. 17 is composed of two single-panel scaffoldings arranged over corners, each of which is designed as shown in FIG. 15, to which reference is hereby made.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.
