The present invention relates to a support structure and an antenna mast for the assembly of mobile radio equipment

The attachment of technical components such as panel antennas, directional radio antennas, radio remote units and the related accessories on e.g. Pipe lattice masts or monopolies is becoming more and more complex due to the technological advances in the mobile communications industry and the associated, continuously expanding expansion stages with regard to static requirements, space requirements and accessibility for assembly and maintenance. In addition, not only the amount of system technology components is increasing, but also the trend towards the establishment of sharing statues, in order to conserve resources and to preserve the town and landscape, where several radio network operators share an antenna mast and, consequently, the above challenges are further intensified.

In the early days of mobile radio, antennas with the required orientations could be attached directly to an antenna mast. Due to various expansion stages, this has not been possible for a long time due to space constraints. As a rule, vertical support tubes are therefore used, to which the mobile radio equipment can be clamped and which in turn

can be attached to the antenna mast using horizontal extension arms

the. As a result, the support tubes are at a distance from the antenna mast and create space for the installation of bulky antennas. Examples of such support structures are in the documents WO 2017/1619231 A1, US 2014/0179244 A1, US 2018/0026327 A1, FR 2 827 4223 A1, WO 20123/185925 A1, EP 1 251 583 A1, WO 2016/0602305 A1, US 6 513 299 and US 5 649 402;

However, the space on the mast or corner post for mounting such extension arms is limited, which increases the amount of mobile radio equipment that can be mounted on the mast, e.g. the number of antennas, limited. Panel antennas usually have three different orientations for each mobile station and radio network operator. For antennas positioned next to each other, a certain distance from each other and a so-called clearance angle of mostly 120 ° must be taken into account, within which - viewed in the plan - in addition to the alignment axis of the antenna, an additional 60 ° to the left and 60 ° to the right as well as 30 ° viewed in side view There must be no building substance or physical obstacles above the top and bottom of the antenna. In addition, antennas are the same

Alignment is in alignment, i.e. are located in the same vertical plane and at the same height. Finally, with regard to the antenna arrangement, there is also the geometric restriction that an undisturbed ascent area for the maintenance

staff from 60 x 60 cm to 80 x 80 cm without obstacles

Should be available

Last but not least, the weight of the mobile radio equipment to be mounted on the mast is increasing due to constantly increasing requirements. For example, antennas for 5G mobile radio networks each consist of a group of directional radiators, which can weigh up to 50 kg per antenna.

The invention aims to address the disadvantages mentioned

to overcome the state of the art and a support structure

to create for the installation of mobile radio equipment on an antenna mast, which is space-saving, highly stable and easy to maintain,

In a first aspect, this goal is

structure of the type mentioned in the introduction, which invented

According to the invention, instead of a conventional cantilever arm for the support tubes, a platform that can be walked on for maintenance purposes is used, which due to its expansion carries several support tubes at a distance from one another. Replacing conventional cantilever arms with such a platform also reduces the susceptibility to vibrations of the support structure and thus also allows the installation of heavy loads, such as a large number of 5G mobile radio antennas.

The combination of several support tubes on a single platform, which is connected via a single anchoring device, e.g. A clamp, which can be mounted on the stem of the antenna mast in one step, on the one hand reduces the space required on the stem per support tube and, on the other hand, allows the mobile radio equipment to be preassembled on the support tubes and the platform on the ground, so that they e.g. can be hoisted in one step by means of a crane and mounted on the mast. At the same time, the walk-on platform eliminates the need to attach a maintenance platform near the mobile phone

can be detected. The result is a highly stable, space-saving and maintenance-friendly support structure. According to a particularly preferred embodiment of the

Pipe clamp in which a support tube is detachably held. The support tubes and platforms of the invention can thereby be modularized, which simplifies production, storage, transport and assembly. An individual support structure can then be put together on site from a standardized set of support tubes and platforms, for example, and assembled on the mast.

It is particularly advantageous if the support tube held in the pipe clamp holds at least one other support tube via cross struts. The support tubes connected via cross struts thus form a support tube group or a support tube frame, of which only a single support tube has to be clamped in the tube clamp of the platform, which considerably facilitates the assembly. The support tube group can also be prefabricated in a modular manner, in particular with predefined distances between the support tubes in order to achieve predefined antenna distances for the antennas mounted thereon. A support tube frame with mobile equipment pre-installed on it, possibly also pre-assembled in the tube clamp of the platform, can then be pulled up in one step and mounted on the mast,

The platform can be in the form of a disk, for example

or a plate, over the circumference of which the distribution

It is particularly advantageous if the other sides of the platform mentioned form three of the edges of a trapezoid. If the corner angles between these three edges are chosen to be 120 °, for example, these edges can be used as references for the mounting of antennas with antenna main beam directions diverging by 60 ° in each case. Adjusting the antennas on site can be made considerably easier for the fitter because he can orientate himself on the edges of the platform.

A further preferred embodiment of the invention is characterized in that it has at least two platforms of the type mentioned, one above the other with a vertical spacing, which are connected to one another via their support tubes. The superimposed platforms can

Another advantageous embodiment of the support structure according to the invention, which is intended for mounting on a corner post of a three or more-sided antenna mast, is characterized in that the support tubes of a platform are arranged in plan view at the corners of an isosceles triangle, the apex angle of which is the angle between corresponds to the sides of the antenna mast adjacent to the corner post. The support tubes of several platforms arranged around such a three-pole or multi-pole antenna mast are therefore on each side of the antenna mast

Support structure at least two next to each other with horizontal spacing

At least three platforms are preferably arranged in a circle around the antenna mast, each connected in pairs via cross struts. This results in a wreath of platform mounted around the mast

men with support tubes, which achieves particularly high stability.

To further increase stability, one end of an inclined strut can optionally engage on the underside of each platform, the other end of which is equipped with a clamp for mounting on the respective stem of the antenna mast.

The platforms can be formed from cast parts or, for the purpose of reducing weight, from tread plates or perforated plates provided with struts, grooved and / or folded. Walk-on gratings are preferably used for the platforms in order to avoid the accumulation of snow and rainwater.

In a second aspect, the invention provides an antenna mast for assembling mobile radio equipment, with at least one handle, on which at least one supporting structure of the type disclosed is mounted by means of its anchoring device. The

Anchoring device can be a clamp by means of

which the support structure is releasably clamped to the handle, O-

The invention is explained in more detail below with reference to exemplary embodiments illustrated in the accompanying drawings. The drawings show:

1 to 3 show a support structure 1 for mounting various mobile radio equipment 2 on a handle 3 of a (here: single handle) antenna mast 4. The mobile radio equipment Z2 can be any type of rod, panel or directional radio antenna 5, 2G6, 236G6, 46, 56 mobile radio antenna 6, antenna driver or control electronics such as radio remote units 7 or the like. act. In the case of directional radio antennas 5 or mobile radio antennas 6, these generally have a defined radiation direction 8 and a defined radiation angle 9 and require predetermined mutual mounting distances and angles, as indicated schematically in FIG. 2.

The support structure 1 comprises at least one - essentially horizontal platforms 10 - four in the example of FIGS. 1 and 2 and two in the example of FIG. 3. Each platform 10 is on one side with an anchoring device 11, e.g. a clamp, clamp, a round steel bracket, tension band or the like, equipped for mounting on the antenna stem 3, on one (Fig. 1, 2) or more (Fig. 3) other sides of its circumference, the platform 10 at least holds overall

two (or more) substantially vertical, from each other

spaced support tubes 12. On the support tubes 12 is in each case

Instead of anchable anchoring of the platform 10 on the handle 3 by means of a clamp, clamp, a round steel bracket, tension band or the like. the anchoring device 11 can also be non-detachable, e.g. as a weld between platform 10 and handle 3.

In the simplest case, the support tubes 12 can also be welded to the platform 10. To modularize the supporting structure 1, the supporting crocodiles 12 are, however, held in pipe clamps or pipe clamps 14, which are mounted on one or more sides of the platform 10, but not on the side having the stem anchoring device 11, for example screwed or welded on. The term “pipe clamp” used here encompasses any type of clamp, clamp, round steel bracket, tension band, etc., which is suitable for clamping anchoring tube 12. Each support tube 12 can be held in its own tube clamp 14 {Fig. 3}, or a support tube 12 held in a pipe clamp 14 can hold additional support tubes 12 via cross struts 15 (FIGS. 1 and 2).

5a to 5c show different variants of such groups of support tubes 12, which are connected to one another via cross struts 15 to form a support tube group 16. For example

In the example of FIG. 4, instead of a platform 10 lying above it, the upper cross strut 15 of the support tube group 16 is held by a bracket 17 which is mounted on the arm 3.

6a to 6d show different variants of platforms 10. In the embodiments of FIGS. 6a and 6b

is the platform 10 each formed as a grating, at

6c and 6d in each case as a tread plate with reinforcing struts or grooves 18. In the leather of the pipe clamps 14 of the platforms 10, a single support tube 12 or one of the support tubes 12 of a support tube group 16 can be mounted,

The platform 10 has in each of the examples shown

a polygonal outline comprising said one side 19,

which has the anchoring device 11 for mounting on the antenna stem 3, and at least two, e.g. three (FIGS. 6a, 6c) and five (FIGS. 6b, 6d) other sides 20-24, which are each equipped with one or more support tubes 12. In the embodiment with pipe clamps 14, the other sides 20-24 of the platform 10 thus have a total of at least two pipe clamps 14, none, one or more than one pipe clamp 14 being able to be provided on one of the sides 20-24. In the embodiments of FIGS. 6b to 6d, the sides 20-22 of the platform 10 each form the edges of a trapezoid.

The position of the pipe clamps 14 or support tubes 12 on the platform is advantageously chosen such that the support tubes 12 mounted on the platform 10 - as seen in the plan view of FIGS. 65a-6d - are arranged at the corners of an isosceles triangle, the apex angle x correspond to the angle β between the sides 25-28 of a three- or multi-pole antenna mast 4 adjoining the respective corner post 3, see FIGS. 7 to 10: in the case of a three-post antenna mast 4 (FIGS. 7, 8, 10}, the angle is β between adjacent sides 25, 26; 26, 27; 27, 25

there antenna mast 4, for example 60 °, in the case of a four-pole antenna mast 4, the angle β between adjacent sides 25, 26; 26, 27; 27, 28; 28, 25 of the antenna mast 4 each 920 °, etc. etc., returning to FIGS. 6a to 6d are the support tubes 12

thus positioned on the platform 10 such that for

three-legged antenna masts 4 the apex angle x of the isosceles triangle 60 ° formed by the three support tubes 12 (FIG. 6c) or by the first, third and fifth support tube 12 (FIGS. 65a, 6b, 6d)}). As a result, the support tubes 12 lie along one of the sides 25-27 of a three-post antenna mast 4 exactly in an alignment line F which is parallel to the respective side 25-27 of the antenna mast 4. As shown in Fig. 6b, the apex angle is "x" of an isosceles triangle, at the corner points of which are the second, third and fourth support channels 12 of the platform 10, e.g. 90 °. This configuration is therefore particularly suitable for a four-pole antenna antenna mast 4, as shown in FIG. 9. Here, too, the support tubes 12 are each in alignment lines F, which are parallel to the sides 25-28 of the four-post antenna mast 4,

Cross struts 15 are interconnected. The cross struts 15 here are simultaneously the cross struts of a support tube group 16 with three support tubes 12, of which the two outer support tubes 12 are each mounted in a tube clamp 14 of a platform 10. The cross struts 15 or support tube groups 16 thereby stiffen the platforms O0 lying next to one another, and the support structure forms, as it were, a “ring” around the antenna mast 4.

In each of the embodiments in FIGS. 7 to 10, a plurality of platforms 10 can be arranged one above the other, as shown in FIG. 1, so that a multi-storey supporting structure 1 results. FIG. 11 shows two such multi-storey support structures 1, each with three superimposed platforms 10 on two corner posts 3 of an antenna mast 4. Analogously to FIG. 10, the support structures 1 from FIG. 11 can again be connected to a coherent support structure 1 via cross struts 15.

It is understood that more than three platforms

men 10 can be arranged one above the other, e.g. to create a four or more storey support structure 1.

In FIG. 11, oblique struts 29 are also shown, which engage with one end 30 on the underside of a platform 10 and the other end 31 of which is supported by a clamp 32 on the respective stem 3 of the antenna mast 4.. The middle and upper platforms 10 of the three-story support structures 1 can optionally be provided with such oblique struts 292.
