Description

The invention relates to a statically and electrically optimized self-supporting tubular roof structure for receiving antennas and technical Components.

The antennas and their system technology installed under the roof structures should not easily identified as antennas or antenna systems can be.

Antenna systems are built according to central or regional guidelines site-specific.

Because the required antenna heights in most urban areas Antenna locations are primarily at least 15 m multi-storey houses with saddle or flat roofs.

These roofs are usually for snow, wind and people loads designed and therefore not to take larger additional loads suitable.

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

• - Weight increase through larger steel cross sections and larger wind attack areas,
• - Greater moments of force on the mast base 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 publications DE 39 42 287 A1 and GB 2239463 A are tiltable masts.

GB 2239463 A describes a cylindrical support and holding structure for Antenna structures disclosed that are partially lowered and rotatable is. The support and support structure consists of a foot section and an upper part connected to this foot part via a tilting bearing. That the Antenna construction receiving top and that with the base connected foot part of the support and support structure are vertical Extent arranged one above the other. The one that can be folded relative to the foot section Upper part has a tubular cylinder on its head area, on which the exposed antenna construction is attached. The loading of the and support structure with antennas is 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.

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

• - a double-walled lower cylinder with stiffeners,
• - a substructure for folding or not folding Execution of the lower cylinder; with the foldable substructure assembly and inspection work should be made easier
• - an upper one connected to the upper end of the lower cylinder Cylinder that is between a lower cylinder and an upper cylinder placed connecting element with the lower cylinder non-positively is coupled
• - An arrangement of antenna holder located in the upper cylinder with antennas attached and over the antenna bracket and / or in the slotted lamellar body of the antenna holder inserted compensation cylinder. The antenna bracket in interaction with the upper cylinder promotes 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 cylinders walls can also be stabilized by a stabilizing Material such as foam and the like can be filled.

The lower cylinder is with its lower end on a substructure pushed on or pushed into a substructure with which his Stability is guaranteed. The substructure consists of a hinged, directly or spaced one on top of the other Double plate on the side facing away from the hinge side is non-positively lockable. This makes the entire system foldable.

On the upper mounting plate is a mast foot with a vertical one double pipe attachment attached, which is dimensioned so that the lower Cylinder form-fitting between the two walls - i.e. in the Annular gap - of the double pipe attachment can be inserted.

About this pair of clamps from the double pipe shoulder of the mast base with Pressing effect on the two walls of the lower one in between Cylinder, the cylinder system is non-positively connected and sufficient stiffened and fixed at the same time.

Requirement for the coaxial wall-to-wall arrangement from the bottom Cylinder and double pipe neck of the mast base is that of the annular gap between the double pipe neck of the mast base about the thickness of the Total wall of the double special cylinder corresponds, so that the lower Cylinder can be inserted tightly into the annular gap.

The mast foot can be on the upper movable leg of the double plate both welded and screwed and has Inspection openings in the pipe socket for receiving and access to the Fasteners for cable connections and other technical Institutions.

Such inspection openings can create a space omitted under the double mounting plate. In this case, the  Cable connections via the clearance from below into the cylinder system introduced.

To create such a space between the fastening Double plate and the mounting level (roof area) serves a separate Distance construction. In the simplest case, this spacing construction exists from a base plate attached to the roof surface and vertical struts for stable connection of the base plate to the lower part of the Fixing double plate.

With this space there is the advantage that when the Entire system, the plug connections do not have to be disconnected.

The height of the vertical pipe neck is from the total height of the Pipe system (lower cylinder and upper cylinder) dependent and can be up to be about 1.0 m.

The heights or lengths of the two spaced apart over the annular gap Pipe approaches can be different.

The lower cylinder has a diameter of approximately 4 to 6 m of a maximum of about 400 mm and is at its upper end under intermediate circuit of the connecting element with the upper cylinder connected.

The connecting element consists of two pipe sockets on the top and Underside of a perforated disc larger in diameter are attached. The both pipe sockets can have a different diameter. The perforated disc has one in the middle for carrying out the Cable sufficiently large opening.

When the connecting element is non-positively mounted, the lower one Pipe socket in the upper end of the lower cylinder and the upper Pipe socket inserted into the lower end of the upper cylinder.  

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

• 1. Static optimization of the entire system through significant reduction the wind attack areas 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 the upper cylinder is to be accommodated by the compen sations cylinder optimally permeable to the radiated frequency.
• 3. By its stele-like shape and color design or Continuation of the color design of the antenna system Building should have the character of a purely function-oriented radio and Transmitter system can be eliminated.

The antennas themselves are positioned on one in the upper cylinder Antenna bracket attached, which consists of the three components lid below, Lid on top and the lamellar body in between with three star-like arranged continuous wall stiffeners (slats).

The lid fits positively in the upper part of the Fastener while the upper cylinder is on the outer upper Wall of the connecting element pushed on and non-positively is 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 has three beams formed, the three slats leading radially away from the central axis enclose an angle of 120 ° each.

To connect the slat body of the antenna bracket to the Compensation cylinders are those on the end faces and continuously parallel to the Areas of the lamellar body and Compensation cylinder slotted in opposite directions at the same radial distance executed and can be pushed into each other via these slots.

• - A lid 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 one continuous preferably three-beam lamella reinforcement and Breakthroughs in the cylinder wall for microwave windows in the upper one Area and revision window in the area below,
• - a mast foot with a feed-through for the power cable,
