Plug-in head ventilator for roof structures

The invention relates to a plug-in head ventilator for flat roof constructions with single- and double-shell roofs, as well as warm roofs, and consists in that a pipe provided with a foot flange is provided, a conical push-on hood is placed on its end is, the bottom of the slip-on hood from the inside to the outside, has a slope and inside with a, with a: Thread or a profile provided plug-on part continues, and that the bottom is outside with a number of drain openings is provided while the top the slip-on hood has ventilation nozzles.

3 ::. C design according to the invention provides that the Aufsteckhiiubc has the shape of a spherical cap, the bottom running horizontally and inside at the transition to the plug-on part

is provided with an annular bead.

The well-known nozzle vent or metal snorkel vent are designed so that the condensation water deposited on the walls of the ventilator does not follow could be discharged outside. This resulted in a concentrated accumulation in the lower area of the fan from precipitation, so that the underlying roof ceiling was always supplied with new moisture.

In contrast, the condensation water formed runs on the inner surfaces in the plug-in head ventilator according to the invention of the slip-on part to the outside via drainage openings. The fan is used in particular for renovations from Wa rind η that are caused by poor roofing are permeated by moisture with their insulating material. In this rehabilitation process, you can in the case of a new covering, the heat-insulating materials are retained if, for example, such ventilators are used subsequently. With new warm roofs that no ventilation possibilities through a pressure compensation layer to the outside air, these ventilators can be set and then lead the accumulating Diffusion moisture coming from inside the room the outside air. In the case of double-shell cold roofs, especially wooden roofs, these fans can have a Provide additional ventilation, so that you can bring a more targeted ventilation into a double-shell roof can. Practice has shown that a wooden roof depending on the floor plan and depending on the rafter position can not always be ventilated through the outside air, so that a such condensation-proof deaerator for the solution

this task is particularly suitable.

Further features of the invention emerge from the following description of exemplary embodiments in FIG Connection with the drawings and claims.

It show, in schematic sketches,

Figure 1 shows a cross section of a built-in plug-in head ventilator with a cone-shaped slip-on hood,

2 shows a plan view of FIG. 1 and

Figure 3 shows another embodiment of the slip-on hood.

FIG. 1 shows the installation of the plug-in head ventilator according to the invention on a Bexon ceiling 1. This concrete ceiling is given a cold bitumen primer 2 above, below Recess of an opening for the foot flange 5 of the pipe, a vapor pressure equalization and vapor barrier - layer 3 is provided. The foot flange 5 has a number of suction grooves 6. The end of the tube 13 is with a Basket thread or a Ucppengewinde provided on which the conical plug-on hood 14 can be placed. The bottom 15 of the slip-on hood 14 has an from the inside outward gradient and settles inward with a push-on part 9. The push-on part 9 carries a thread or corresponding to the end of the tube 13 Profile. The bottom 15 is external with a number

of drainage openings 11 for the condensation water, as well as air inlet openings 10. The tip of the slip-on hood receives a number of vent nozzles 12. The plug-in head ventilator is sealed at the installation point on the roof in such a way that a moisture-impermeable roof skin 4 covers the base flange 5 and extends to about the jacket of the pipe 13. Subsequently, a sleeve 7 is pushed over the pipe 13, the foot flange 5 and part of the pipe 13 being covered. Finally, a cover strip 8 resting on the tube 13 is pushed over the cuff 7. Characterized in that - the possibility is given to remove the Aufsteckhaube T4 of the tube, the cuff 7 can ₉ which are usually made of plastic, very simply pushed onto the pipe. 13

The slip-on hood 14 can advantageously be made of plastic However, galvanized sheet metal can be used to the same extent for this.

The push-on hood 14 shown in Figure 3 has the In the form of a spherical cap, with the bottom 15 'running horizontally. At the transition to the plug-on part 9 is a Annular bead 16 is provided, which is intended to prevent condensation water from running into the pipe 13.
