Definitions

• the present invention relates to a platform, comprising a bearing part and coupled thereto means for connecting an antenna mast or the like to the bearing part.
• antenna masts especially for the so-called GSM base stations, as well as for UMTS base stations and the like, on high objects such as roofs of buildings, often the antenna masts are mounted on flat roofs of flat buildings and the like.
• the antenna's mounting point at a height of 30 metres.
• the antennae themselves are mounted on one or more masts having a height of approximately 5 metres, positioned on the roof .
• the individual bases are subsequently finished to be water-tight.
• the platform is then mounted on the individual base. If the roof itself has insufficient bearing power, for example, in the case of wooden or steel roofs, the underlying supporting construction of trusses is used for fastening the platform. To this end a hole is made above a truss through the entire roof construction.
• the individual base is then mounted on the truss. Finally the individual base is finished to be water-tight, which has to be done very precisely.
• the antenna platform according to the invention is characterized in that the bearing part consists of substantially similar, interchangeable and interconnected elements, and in that the platform comprises supporting means, which, without being connected, support the platform on a mounting face, the supporting means being adjustable in height and at the side facing the mounting face, comprising a vibration- isolating construction, for example, a vibration-isolating material such as a rubber-like material.
• a vibration- isolating construction for example, a vibration-isolating material such as a rubber-like material.
• the elements consist of elongated elements.
• the supports consist of longitudinal beams and cross beams, providing a simple modular system, allowing simple extensions to be carried out to the platform at the place of destination.
• the syBte according to the invention is very advantageous especially when the platform is to be placed on a flat roof of a high building.
• the separate modular parts may be taken to the place of destination, to subsequently be assembled there.
• the platform may be assembled in an assembly room and be placed directly on to the roof or the like, in accordance with the invention, it is not necessary to anchor the construction to the building.
• the supporting means are adjustable in height, it is simple to level out possible unevennesses in the mounting face.
• the vibration-isolating construction of the supporting means wherein said construction may consist, for example, of a vibra ion-isolating material such as a rubber-like material, provides a number of advantages. It has a high friction coefficient, which minimizes any movement of the platform over the mounting face. Such material is relatively soft so that damage to the mounting face is prevented. It is also vibration-isolating. Finally, such material has a low thermal conduction coefficient so that thermal bridges to the mounting face are avoided.
• a vibra ion-isolating material such as a rubber-like material
• Embodying the supporting means with a solid core, for example, metal provides a good load distribution over a larger area; maximally as large as the surface area of the supporting means themselves .
• the elements are preferably provided with a plurality of fastening points for the supporting means in order to allow them to be fastened to the platform at different positions. This means that they can be positioned, for example, exactly above roof trusses. This allows the supporting means, moreover, to be attached 5 under the platform such that they do not rest on elements mounted on the roof such as chimneys and the like. To this end the elements comprise fastening positions for supporting means in such numbers that the strength and soundness of the elements are not adversely 10 affected.
• the elements comprise at least two, preferably at least three, and more preferably at leaat four fastening positions for the supporting means.
• a further preferred embodiment provides in the supporting means being pivotingly fastened to the 15 platform.
• the supporting means being pivotingly fastened to the 15 platform.
• the platform may also be provided with connecting means for fastening equipment cabinets that house this system equipment thereto.
• Preferred is an enclosed room on the platform for housing said equipment cabinets.
• the room comprises an air conditioning system and is equipped to accommodate equipment to be used with an antenna system.
• the air conditioning system may comprise a traditional air conditioner or a (mechanical) air circulation system
• the room may comprise a standard fastening whereby different kinds of equipment (cabinets) may be f stened in the room by means of adapters .
• the room comprises means to allow a top
• the top section preferably comprises a niche which, when the top section is mounted on the equipment room, lies in the extended direction of the niche that is provided in the wall of the equipment 5 room.
• the known GSM/UMTS antennae can be placed in such a niche. It is, for example, possible to place a beam transmitter, preferably of the kind known in the art, in the top section. This may then be protected from the surroundings by a material such as polycarbonate, which is 10 substantially permeable with regard to the respective radiation.
• the elements are provided with grids suitable to be walked over. In that case there will be no direct contact with 15 the roof surface during possible maintenance activities. It is also possible to provide fencing around the periphery of the platform. This is especially advantageous if the antenna platform is mounted on a high building.
