Definitions

  • the invention relates to a roof ventilation system for a building, that essentially consists of a roof ventilation pipe and there is a cap that is on or above the free, over Roof-guided pipe end of the roof ventilation pipe can be attached is.
  • Such a roof ventilation pipe is, for example, by the German utility model 295 14 513.7 became known.
  • a cap of the type mentioned is in the German Utility model 296 10 727.1.
  • the cover cap must be designed in this way on the roof ventilation pipe be that an outflow of exhaust air from the roof ventilation pipe secured in a wide variety of wind conditions is. It should be ensured that the flow and pressure conditions in the free end area of the roof ventilation pipe are set so that the exhaust air Flow out of the roof ventilation pipe as congestion-free as possible can and should cover the cap in all weather the penetration of rain and snow into the roof ventilation pipe prevent.
  • the present invention is therefore based on the object to develop a roof ventilation system in which an optimal Outflow behavior of exhaust air from the roof ventilation pipe is guaranteed in a wide variety of wind conditions or is additionally supported.
  • the solution according to the invention consists in a roof ventilation system with a roof ventilation pipe, with means for Flow line for in the direction of the free, led over roof Pipe end of the roof ventilation pipe flowing outside air and with a cap that has a canopy and itself cap walls adjoining outer edge areas of the cap roof with outside the free flow cross section of the Roof ventilation pipe located, in the direction of a roof surface projecting cap ends to which the means spaced from the flow line and opposite on Roof ventilation pipe are arranged, the cap ends and the flow conduit means transverse to the longitudinal direction of the roof ventilation pipe accessible flow outlet openings limit.
  • the roof ventilation pipe, the cover cap and the means for Flow line interact in such a way that the exhaust air and with it moisture from the area of the free Pipe end of the roof ventilation pipe without traffic jams or through the Outside air can flow flow assisted. If in Atmospheric area outside air a roof with the invention, the roof ventilation system flows around a flow direction of the outside air in the direction of the roof pitch a flow component in the direction of the Longitudinal axis of the roof ventilation pipe is directed. This Part of the outside air flows partly through the roof ventilation pipe upwards, through the means for flow conduction deflected and led past the cover cap.
  • the ends the flow conduit means and the cap ends arranged opposite each other so that the flowing past Outside air in the space between the cap ends and Exhaust air entering the ends of the flow conduit sweeps away.
  • the flow conduit means that to guide the outside air past the cover cap, without the outside air in the area of the inside surface the cap can flow.
  • Cap walls of the cover cap are outside the free flow cross section of the roof ventilation pipe attached so that Condensation forming on the underside of the cover cap can run freely in the direction of the cap ends.
  • the condensed water is discharged to the outside and cannot run back into the interior of the roof ventilation pipe.
  • the guide surfaces for condensed water can provide. If there is condensation on the underside of the cover cap forms, this can be done at the ends of the caps and accordingly provided, not at this point described fasteners run along.
  • the condensed water but can no longer in the interior of the Roof ventilation pipe. Due to the suction effect or the circulating air behavior of the outside air flowing around the cover cap the moisture that forms at the cap ends dissipated with flow support.
  • the means for flow conduction are on the outer peripheral surface of the roof ventilation pipe, so that this also ensures is that the moisture is not in the interior of the roof ventilation pipe can flow back.

The cover cap can therefore no flow resistance form for this outside air.
  • Cap walls of the cover cap and wind deflectors of the wind deflector can be symmetrical and mirror images of each other be arranged so that the outside air directed at the cap ends can flow past. Wind flaps and cap ends are also mirror images of one plane, which are perpendicular to the longitudinal direction of the roof ventilation pipe runs. The mirror symmetry of cap walls and wind deflectors ensure air outlet openings, from which exhaust air from the roof ventilation pipe evenly and flow-assisted into the atmosphere by the outside air can flow. Cap walls and wind deflectors can be used different embodiments in terms of their shape and Size can be varied.
