Description

The invention relates to a statically and electrically optimized self-supporting tubular roof structure for receiving antennas and technical components.
The antennas installed under roof structures and their system technology should not be easily identified as antennas or antenna systems.

Antenna systems are set up according to location-specific central or regional requirements.
Since the required antenna heights in inner cities are at least 15m in most cases, antenna locations are mainly multi-storey houses with saddle or flat roofs.
These roofs are usually designed for snow, wind and personal loads and are therefore not suitable for accepting larger additional loads.

• Gewichtserhöhung durch größere Stahlquerschnitte und größere Windangriffsflächen,
• größere Kraftmomente am Mastfuß und damit
• die Notwendigkeit der Krafteinleitung in tragende Mauern der Bauwerke.

The further expansion of mobile radio networks means that existing mast systems will be more heavily occupied. That means

• Weight increase due to larger steel cross sections and larger wind attack areas,
• greater moments of force on the mast foot and thus
• the need to apply force to the load-bearing walls of the building.

From US 5,963,178 an arrangement for receiving antennas, associated cables and technical components known from a Cylinder system exists.

The antennas are arranged at the upper end of a one-piece mast are covered by a cylindrical fiberglass housing. This Fiberglass housing is for ease of access to the antennas movable on the antenna mast.

The subject of the publications DE 3942287 A1 and GB 2239463 A are tiltable masts.
GB 2239463 A, for example, discloses a cylindrical support and holding structure for antenna structures, which is partially lowerable and rotatable. Here, the supporting and holding structure consists of a foot part and an upper part connected to this foot part via a tilting bearing. The upper part receiving the antenna construction and the base part of the supporting and holding construction connected to the base are arranged one above the other in a vertical extension. The upper part, which can be folded relative to the foot part, has a tubular cylinder on its head region, to which the uncovered antenna construction is fastened. The supporting and holding structure is equipped with antennas as intended in the folded state.

US 5,581,958 relates to an antenna mast with uncovered antennas with a Chamber for technical equipment located near the mast base Components to which inspection doors are attached.

The mast systems with a partly pronounced substructure fit together inadequate in the architectural environment of an urban development Character. Economic aspects of building and revision of the Insufficient attention is paid to antenna systems.

The object of the invention is therefore to provide antenna systems with a to develop tubular structure leading to a reduction in construction costs lead to the described structure of the mobile radio networks and in which the Expenses for performing revisions to the mechanical and electrical part of the antenna systems can be significantly reduced.

An inventive solution to this problem is in claim 1, 4 and 13 indicated, further developments of the invention are in the subclaims characterized.

According to the concept of the invention, the tubular roof structure is static and electrically optimized self-supporting cylinder system, which is built according to the modular principle and its parts easily assembled and can be dismantled.

• einem doppelwandigen unteren Zylinder mit Aussteifungen,
• einer Unterkonstruktion zur klappbaren oder nicht klappbaren Ausführung des unteren Zylinders; mit der klappbaren Unterkonstruktion sollen Montage- und Revisionsarbeiten erleichtert werden,
• einem an das obere Ende des unteren Zylinders anschließenden oberen Zylinder, der über ein zwischen unteren Zylinder und oberen Zylinder platziertes Verbindungselement mit dem unteren Zylinder kraftschlüssig gekoppelt ist,
• einer im oberen Zylinder befindlichen Anordnung von Antennenhalterung mit daran befestigten Antennen und über die Antennenhalterung und/oder in den geschlitzten Lamellenkörper der Antennenhalterung hinein geschobenem Kompensationszylinder. Die Antennenhalterung fördert in Wechselwirkung mit dem oberen Zylinder die Fixierung und Versteifung des Zylindersystems.

In a first preferred embodiment, the cylinder system consists of:

• a double-walled lower cylinder with stiffeners,
• a substructure for the foldable or non-foldable execution of the lower cylinder; with the foldable substructure, assembly and inspection work should be made easier,
• an upper cylinder adjoining the upper end of the lower cylinder, which is non-positively coupled to the lower cylinder via a connecting element placed between the lower cylinder and the upper cylinder,
• an arrangement of antenna holder in the upper cylinder with antennas attached to it and a compensation cylinder pushed over the antenna holder and / or into the slotted lamellar body of the antenna holder. In interaction with the upper cylinder, the antenna holder promotes the fixation and stiffening of the cylinder system.

The lower cylinder consists of two concentric in the circular distance from about 3 to 6 cm inside each other arranged cylinder walls. Here are the two cylinder walls in their position by spacers fixed to each other. The annulus volume between the two cylinder walls can also be stabilized by a stabilizing Material such as foam and the like can be filled.

The lower end of the lower cylinder is pushed onto a substructure or inserted into a substructure, which ensures its stability. The substructure consists of a double plate which can be hinged, is located directly or at a distance from one another and can be non-positively locked on the side facing away from the hinge side. This makes the entire system foldable.
A mast foot with a vertically standing double pipe extension is attached to the upper mounting plate, which is dimensioned so that the lower cylinder can be inserted with a positive fit between the two walls - i.e. in the circular gap - of the double pipe extension.
The cylinder system is non-positively connected and sufficiently stiffened and at the same time fixed by means of this pair of clamps consisting of a double pipe shoulder on the mast base with a pressing effect on the two walls between the lower cylinder.

A prerequisite for the coaxial wall-to-wall arrangement of the lower cylinder and double pipe neck of the mast base is that the annular gap between the double pipe neck of the mast base corresponds approximately to the thickness of the total wall of the double special cylinder, so that the lower cylinder is pushed tightly into the annular gap can be.
The mast foot can be both welded and screwed onto the upper movable leg of the double plate and has inspection openings in the pipe socket for receiving and access to the connecting elements for cable connections and other technical equipment.
Such inspection openings can be omitted when creating a space under the mounting double plate. In this case, the cable connections are inserted into the cylinder system from below via the space.
A separate spacing construction is used to create such a space between the double fastening plate and the mounting level (roof surface). In the simplest case, this spacing construction consists of a base plate fastened to the roof surface and vertical struts for stable connection of the base plate to the lower part of the double fastening plate.
This distance space has the advantage that the plug-in connections do not have to be loosened when the entire system is folded down.

The height of the vertical pipe extension depends on the total height of the pipe system (lower cylinder and upper cylinder) and can be up to approximately 1.0 m.
The heights or lengths of the two pipe lugs spaced apart via the annular gap can be different.

The lower cylinder has a length of approximately 4 to 6 m and a maximum diameter of approximately 400 mm and is non-positively connected to the upper cylinder at its upper end with the interposition of the connecting element.
The connecting element consists of two pipe sockets, which are attached to the top and bottom of a perforated disc with a larger diameter. The two pipe sockets can have a different diameter. In its central area, the perforated disc has a sufficiently large opening for the passage of the cables.
When the connecting element is non-positively mounted, the lower pipe socket is pushed into the upper end of the lower cylinder and the upper pipe socket into the lower end of the upper cylinder.

1. Statische Optimierung der Gesamtanlage durch erhebliche Reduzierung der Windangriffsflächen auf WA < 50 cm/m und der Gesamtbelastung auf < 0,75 KN/m.

2. In dem Längenbereich des oberen Zylinders, in dem die Antennen untergebracht sind, soll der obere Zylinder durch den Kompensationszylinder optimal für die abgestrahlte Frequenz durchlässig sein. Mittels des Kompensationszylinders werden die von der einen Zylinderschicht (oberer Zylinder) verursachten Reflexionen durch die Reflexionen an der anderen Zylinderschicht (Kompensationszylinder) kompensiert. Dazu ist der Abstand der konzentrischen Anordnung der beiden Zylinder entsprechend einzustellen.

3. Durch seine stelenartige Form und farbliche Gestaltung bzw. Fortführung der Farbgestaltung des die Antennenanlage tragenden Gebäudes soll der Charakter einer rein funktionsorientierten Funk- und Sendeanlage eliminiert werden.

The resulting pipe system can optionally be built up to heights of 9.9 m. This pipe system has three functions.

1. Static optimization of the entire system by significantly reducing the wind attack area to WA <50 cm / m and the total load to <0.75 KN / m.

2. In the length range of the upper cylinder in which the antennas are housed, the upper cylinder should be optimally permeable to the radiated frequency by the compensation cylinder. By means of the compensation cylinder, the reflections caused by one cylinder layer (upper cylinder) are compensated for by the reflections on the other cylinder layer (compensation cylinder). The distance between the concentric arrangement of the two cylinders must be set accordingly.

3. The character of a purely function-oriented radio and transmitter system is to be eliminated by its stele-like shape and color design or continuation of the color design of the building carrying the antenna system.

The antennas themselves are attached to an antenna bracket positioned in the upper cylinder, which consists of the three components lid below, lid above and the slat body in between with three star-shaped, continuous wall stiffeners (slats).
The cover at the bottom fits into the upper part of the connecting element in a form-fitting manner, while the upper cylinder is pushed onto the outer upper wall of the connecting element and non-positively connected.

The lid at the bottom has a sufficiently large recess for Carrying out the antenna cables.

The top lid has a larger diameter than the top cylinder and thus closes the upper one like a hood and provides a form-fitting seal Cylinder.

Both cover elements become frictional with the lamellar body connected and led. This slat body is used to hold the Antennas that are non-positively attached to this. The slat body has continuous, star-shaped stiffeners (slats), which positively stabilize the compensation cylinder and the guidance of the antenna bracket in the upper cylinder when assembled with antennas and other technical equipment.

In an advantageous embodiment, the lamellar body is designed with three beams, the three lamellas leading radially away from the central axis each enclosing an angle of 120 °.
To connect the lamellar body of the antenna mount to the compensation cylinder, the areas of the lamellar body and compensation cylinder that meet at the end faces and continuously parallel to the central axis are slotted in opposite directions at the same radial distance and can be pushed into one another via these slots.

• einen Deckel oben mit größerem Durchmesser als der obere Zylinder zum formschlüssigen Verschließen des oberen Zylinders.

In a second preferred embodiment, the cylinder system according to the invention has the following structure or the following deviations from the first embodiment:

• a single-walled or double-walled lower cylinder, preferably with three-beam lamella reinforcement, the three radially extending lamellae being designed as wall stiffeners which are continuous over the length of the lower cylinder and upper cylinder,
• a substructure, as explained in the first embodiment,
• an upper cylinder which is non-positively connected to the lower cylinder via a connecting element, as in the first embodiment,

Arranged above the lamella body and / or inserted into the slotted lamellae of the antenna holder is, in a manner analogous to the first embodiment, a compensation cylinder slotted in opposite directions.
• a lid at the top with a larger diameter than the upper cylinder for positive locking of the upper cylinder.

The lamella reinforcement in turn has an angle of 120 ° between the slats arranged in a star pattern. Such slat reinforcement can also retrospectively as a correspondingly elongated continuous Component positively in the upper cylinder and lower cylinder be introduced.

In a third preferred embodiment, the cylinder system consists of

• a lower cylinder in the total length of the roof structure with a continuous preferably three-beam lamella reinforcement and openings in the cylinder wall for microwave windows in the upper area and inspection windows in the area below,
• a mast foot with a feed-through for the power cable,

• a compensation cylinder, which preferably covers the microwave windows from the outside and is fixed in this position,
• Antennas that are mounted in the area of the compensation cylinder in the 120 ° louvre spaces of the lamella reinforcement.

When the antenna system is revised, the revision cylinder is preferably moved downward in the direction of the common axis of the cylinder system, so that access to the antennas is free through the revision window.
The antennas can be moved vertically, ie along the axis of the cylinder system, by means of an additional displacement system arranged on the lamella reinforcement, for example in the form of a rail system. This improves the access conditions to the antennas.
