Abstract

The invention relates to a scaffold structure for an information and/or advertising space, for constructing around a crane tower, especially a building crane. The inventive scaffold structure is characterised by a plurality of arm elements that can be folded up in a compact manner for transport and can be opened out for use.

Description

Support framework for an information and / or advertising space

The present invention relates to a support framework for an information and / or advertising space according to the preamble of claim 1.

A generic support framework for attachment to a mast tower of a crane, in particular a construction crane, is described in DE 299 15 269.3.

Such support structures are used to attach an information and / or advertising space to a mast, for example the mast of a construction crane.

In order to be as independent as possible of possible wind forces and the associated mechanical loads, it is proposed in DE 299 15 269.3 that an inner support is rotatably connected in the circumferential direction or adjustable in the direction of extension with the mast.

This results in comparatively expensive and therefore expensive constructions.

An advertising medium that can be attached to a mast is also described in DE 299 10 410 Ul. Masts for advertising media are shown in US 5,340,065, DE 78 10 361 Ul and DE 89 11 942 Ul.

DE 296 22 940 Ul relates to a climbing device for masts of construction cranes. Telescopic masts are in DE 41 07 344 AI and DE 697 14 696 T2. Finally, further multi-unit advertising media are disclosed in US-954,525 and US-1,930,018.

It is an object of the present invention to provide a support structure of the type specified above which is particularly easy to transport.

This object is achieved by a support framework with the features of claim 1.

Advantageous developments of the carrier framework according to the invention are the subject matter of the subclaims.

The support frame of the above-mentioned type according to the invention further developed in that a plurality of folding elements is provided, which can be folded for a transport state volume saving and folded out for an operating condition.

As a core idea of the invention can be considered to accomplish a downsizing of the support frame for transport purposes by means of retractable elements.

In this way, a very simply constructed carrier framework can be achieved, which is therefore inexpensive to manufacture. The support frame according to the invention can also be operated very easily, since only a plurality of folding elements has to be unfolded to provide the operating state.

Finally, can be achieved by the folding elements a significant reduction of the volume and thus a considerable simplification of the transport. In a preferred embodiment of the support frame according to the invention, a base frame is provided, which is displaceable or fixed to the mast tower can be arranged, wherein the folding elements are pivotally mounted on the base frame. The base frame with the folding elements can then be transported separately and mounted with a minimum of assembly steps on a mast tower of a crane.

The invention has been made primarily with a view to use in construction cranes. In principle, however, the support frame according to the invention can be attached to any suitable mast.

An inexpensive and material-saving variant is characterized in that the base frame is formed in several parts with at least two end frames. Optionally, one or more support frames may be disposed therebetween. In particular, holding frame and / or end frame may extend substantially horizontally. On vertical support members can then be dispensed with, whereby a considerable material and weight savings is achieved.

A high stability is achieved when the base frame completely surrounds the tower in the circumferential direction.

In this context, a particularly simple structure can be achieved if the base frame has a substantially rectangular, in particular square, cross-section. Overall, the base frame may have a substantially cuboid shape.

A particularly simple and space-saving folding is made possible when the folding elements in corners of the Base frame are hinged pivotally. A pivotable suspension of the folding elements can be particularly easily realized, in particular at the edges of the aforementioned cuboid shape.

In particular, the folding elements can be designed as pivotable about vertical axes folding wings. The folding wings may expediently have a rectangular shape in a simple frame construction. In this context, it is also possible to provide a plurality of folding wings in the extension direction of the mast, which can be pivoted independently of each other.

In principle, the individual folding wings of a carrier framework can have different shapes and dimensions. In a particularly preferred simple embodiment, however, four similar folding wings are provided, which are articulated pivotably, for example, on the four longitudinal edges of the cuboidal shape of the base frame.

Conveniently, stabilizing elements are provided for stabilizing the folding elements in the operating state and / or in the transport state.

In design-wise simple and weight-saving variants, these are bracing, in particular wire rope suspensions.

In order to achieve a plurality of operating positions of the folding elements, for example with regard to certain desired geometries of the information and / or advertising space, the bracing can be designed to be adjustable in length. A stable attachment of the base frame to the mast is made possible if a plurality of supporting devices, in particular rollers, are provided for supporting the base frame in relation to the mast tower.

A linear adjustment of the support frame can be accomplished in a simple manner by a drive, in particular a hydraulic device or an electric motor. The adjustment is referred to in this regard as climbing. In this context, it may also be provided to mount or support the support frame in each case on the mast tower, for example on cross members, for which purpose a support frame connected to the base frame is expediently provided.

In a further aspect, the invention relates to a carrier module for an information and / or advertising space. According to the invention, such a carrier module comprises a tower section of a tower of a crane, in particular a construction crane, as well as a support structure according to the invention of the type described above.

In principle, the support frame can be arranged displaceably or fixedly on the tower section. A displaceable in the extension direction of the mast, in the directions transverse to the direction of extension but fixed arrangement of the support frame relative to the mast can be achieved by means of rollers or with the aid of plain bearings.

In a preferred variant, the support frame can be hung at certain heights on the tower section. The possible mounting heights can be predetermined by struts, for example cross struts, of the tower section. In an expedient variant, a plurality of supports, in particular lugs, are provided on the tower section for supporting and / or suspending the support frame. In a simple embodiment, the support frame is firmly connected to the tower piece. In this context, in particular the variant of a holding frame consisting of at least two horizontal end frames and optionally one or more holding frames arranged therebetween can be advantageously realized.

Appropriately, a plurality of brackets are then provided for the spaced attachment of the base frame to the tower section.

The stability of the structure as a whole is provided primarily by the tower piece, so that a less complex structure is sufficient for the support frame as such and accordingly costs can be saved.

In a particularly simple embodiment is completely dispensed with a base frame and the folding elements are pivotally mounted directly on the tower section.

In order to enable the construction of larger information and / or advertising surfaces, it is particularly advantageous if the carrier module is designed such that it is designed for assembly with other similar carrier modules.

In order to reduce the reduction of the information provided by the information and / or advertising surface attack surface for wind forces, a device for folding the folding elements may be provided. The collapse can be automated, in particular, when this folding device is connected to an anemometer and a suitable control and regulating device. Further features and advantages of the invention will be described below with reference to the accompanying schematic figures.

The arrangement of a support frame 14 according to the invention and a support module 10 according to the invention on a construction crane 20 is shown schematically in FIG.

The construction crane 20 shown there has as essential components a mast tower 22, which is constructed from a plurality of tower pieces 24, and a boom 23. At mid-height of the mast tower 22, an inventive support frame 14 is arranged with an advertising surface 11.

Embodiments of the support frame 14 according to the invention and the support module 10 according to the invention will be described below with reference to FIGS. 2 to 9, wherein equivalent components are each identified by the same reference numerals.

A first exemplary embodiment of a carrier module 10 according to the invention and of a carrier framework 14 according to the invention is shown in FIGS. 2 and 3. The support frame 14 consists of a substantially cuboidal base frame 18, which encloses a tower section 24 of a mast tower 22 of a construction crane 20. The support frame 14 is mounted displaceably with respect to the tower section 24, the support taking place by means of rollers 40, which are arranged at each of the four edges of the tower section 24 in pairs and perpendicular to one another.

At corner areas 30 of the cuboidal base frame 18, according to the invention, in each case one folding wing 28 is hinged pivotably about a vertical axis 26 as a folding element 16. FIG. 2 shows the carrier module 10 according to the invention with the carrier frame 14 according to the invention in an operating state in which the total of four folding wings 28 are unfolded so that they are positioned substantially diagonally to the base frame 18. At the folding wings 28 an advertising space 11 is arranged. This advertising surface 11 may for example consist of a flexible material, such as a film or a textile material. A stabilization of the unfolded folding wings 28 is accomplished in the embodiment shown by means of Drahtseilabspannungen 38 as stabilizing elements 36. In the operating state shown in FIG. 2, a total of four similar advertising surfaces 11 are provided by the carrier framework 14, so that the advertising medium can in principle be viewed from all sides.

In the transport state shown in Fig. 3, the folding wings 28 are collapsed and are close to the base support 18 at. The advertising surface 11, not shown in FIG. 3, can either be removed or, if it is formed from a flexible material, folded together and stowed, for example, inside the support frame 14. From the comparison of Figs. 2 and 3, the significant reduction in volume is immediately apparent, which can be achieved with the aid of the support frame 14 of the invention and thus with the carrier module 10 according to the invention.

Two variants of a further embodiment of the invention are shown in FIGS. 4 and 5. From the embodiment shown in FIGS. 2 and 3, the variants of FIGS. 4 and 5 differ in that here the base frame 18 via consoles 46, each of which is an example, with a tower piece 24th a construction crane 20 is connected. As in the embodiment described in connection with FIGS. 2 and 3, folding wings 28, 29, 31 are arranged pivotably about vertical axes 26 in corner regions 30 of the base frame 18. Under vertical should be understood here in general a direction which extends substantially parallel to the extension direction of the mast tower 22, on which the support frame 14 is arranged. In the event that the mast tower 22 is not erected perpendicular to the earth's surface, then this vertical direction would not be perpendicular to the earth's surface.

In contrast to the example shown in FIG. 2, the folding wings 28, 29, 31 are each positioned differently in FIGS. 4 and 5. The folding wings 28 extend in the direction of a support 19 of the base frame 18 in the examples shown in FIGS. 4 and 5. In contrast, the folding wings 31 in FIG. 4 are aligned along the diagonal of the base frame 18. The folding wings 29 in Fig. 4 o finally deviate from the diagonal orientation by about 15.

By this arrangement, which is fixed again in each case with the help of in Fig. 4 and 5 shown in detail Drahtseilabspannungen 38, a trapezoidal cross section of the billboard 11, 13 is possible. This is advantageous for applications in which the advertising area 11, 13 is expected to be viewed only from a half-space.

The variant of FIG. 4 differs from that of FIG. 5 in that the folding wings 28 are wider than the folding wings 29, whereas in the example of FIG. 5, the folding wings 28 and 31 are substantially identical. Another difference is that in FIG. 4 essentially three advertising surfaces 11 of the same size are formed, whereas in FIG. 5 the advertising area 13 visible from the front is larger than the lateral advertising areas 11.

A further exemplary embodiment of a carrier module according to the invention with a carrier framework 14 according to the invention and a tower section 24 of a construction crane 20 is shown in FIG. This variant has essentially the same structure as the example shown in FIGS. 2 and 3. In Fig. 6 in particular the rectangular shape of the folding wings 28, which are pivotable about vertical axes 26, can be seen. Furthermore, the support of the base frame 18 is illustrated on the tower section 24 of the mast 22 by means of a plurality of rollers 40. Finally, the structure of the base frame 18 of horizontal end frame 34 and support frame 32 is illustrated. To support the weight of the support frame 14, a support frame 42 is provided with a support 43. The support frame 42 is laterally fixed by a plurality of rollers 40 relative to the mast tower 22. The support 43 engages in the mast tower 22 and is supported on a cross member of the tower section 24, not shown.

Another variant of the suspension of the support frame 14 on a tower section 24 of a mast 22 will be explained with reference to FIGS. 7 and 8. Fig. 7 shows a detail of the embodiment of Figs. 2 and 3 in a longitudinal sectional view. There, the structure corresponds substantially to that of FIG. 6, but the support 43, unlike the example of FIG. 6, is supported on supports 44 which are attached to the tower section 24. These supports 44 may also be referred to as lugs 44. In Fig. 8, these lugs 44 are shown in detail. As can be seen, these lugs each have on their top and bottom a groove 45, in which the support

43 engages. At adjacent vertical struts of the tower section 24 are each suitably at the same height ridges

Arranged 44 so that the support 43 can each be supported on at least two lugs 44.

A longitudinal sectional view of the example shown in FIGS. 4 and 5 is shown schematically in FIG. As already explained in connection with FIGS. 4 and 5, in this embodiment, the support frame 14 is connected via brackets 46 fixed to the mast tower 24, for example screwed or welded. The base frame 18 of the support frame 14 consists in the example shown of end frame 34, which are arranged horizontally, transversely to the extension direction of the tower section 24.

The folding wings 28 are not shown in Fig. 9. Connecting elements 48 can be used to connect pieces 24 of similar construction. This is preferably done via suitable screw.

With the invention, a new carrier framework and a new carrier module for an information and / or advertising space is provided with which excellent transportability is achieved in a particularly simple and cost-effective manner. In addition, the support frame according to the invention and the support module can be constructed in a particularly simple manner with a few assembly steps, which brings a significant time savings. Overall, the carrier framework and the carrier module described above thus offer considerable technical and economic advantages.
