  • the antenna support structure is usually passed through the roof and is supported vertically on the attic with its lowest shot. Usually the bottom shot is attached to the attic.
  • the antenna support structure is held laterally by the roof leadthrough and / or by supports extending essentially perpendicular to the longitudinal direction of the supporting masts.
  • Approval-free antenna structures are antenna structures, depending on the building regulations of the federal states, for example, a construction height of up to 10 m, the height of the structure being determined from the length of the masts. Approval-free antenna structures of this type are particularly important for the construction of the recently expanding mobile radio networks, specifically for the establishment of the base stations of the individual radio cells.

  • the fastening device for fastening a mast or mast structure is designed such that it receives one or more masts on the one hand and is itself attached to the roof structure or the roof structure on the other hand.
  • the present invention has the following advantages in particular. It enables universal mounting of masts on different roof types, for example on loft, saddle, hip roofs etc., regardless of the respective roof pitch, i.e. essentially for any roof pitch.
  • the invention can also be applied to flat roofs which are designed as rafters roof and have a slight slope.
  • the fastening device according to the invention Due to the exclusive attachment of the mast or mast structure to the roof structure, there is no immediate load distribution, e.g. from a snow load, into the underlying building parts via the mast or antenna structure. In addition, structure-borne noise is avoided in living room ceilings. Furthermore, it is advantageous that the fastening device according to the invention has no or only a slight loss of usable space for the existing donor.

  • the support structure comprising the cross beams, the supports for the holding means and the holding means, and the longitudinal beams together with the supporting mast base span a three-dimensional framework.
  • Such a framework advantageously leads to additional stiffening of the roof.

Abstract

L'invention concerne un procédé et un dispositif de fixation servant à fixer un mât porteur ou un système de mâts porteurs sur la charpente, la lucarne ou le système de comble d'un toit. Selon l'invention, le mât porteur ou le système de mâts porteurs ne repose pas sur les combles du toit, mais les forces portantes ou de maintien du mât porteur fixé sont introduites dans le système de comble. A cet effet, le dispositif de fixation pour fixer un mât porteur ou un système de mâts porteurs est conçu de façon, d'une part, à supporter un ou plusieurs mâts porteurs et, d'autre part, à être fixé lui-même sur la lucarne ou le système de comble.
