The adjacent side parts (3,3';4,4'), made especially of plastically deformable material, have outer longitudinal edges matching the top of the roof covering panels. The middle part leads into the side strips via at least tow lengthwise ridges (6,6';7,7') each possessing a section (5,5') with pre-set length. The deformable material is colour-coated or tin-plated lead, tin or copper. The middle and or side strips can be corrugated or smooth. The side strips have a lengthwise gap (8,8') to form an edging strip (4,4').

Description

The invention relates to a rollable one that allows air to pass through Sealing strips for a ridge and / or ridge cover with one to rest on on a ridge and / or ridge batten and with it adjacent side strips, in particular made of plastically deformable material, the at least with their outer longitudinal edges to the top of Roofing sheets are customizable.

EP 0 341 343 A2 describes a sealing strip for a ridge or Burr cover known. The well-known sealing strip is in several pieces educated. It has a median from an air-permeable, water-repellent and snow-resistant fleece on the side edges Side stripes are attached. The side strips consist of polyisobutylene film strips, in which an expanded metal grid is embedded. Disadvantage of this Rollable sealing strips or ventilation element is the poor one active flow, which is caused by the fact that there are no ventilation openings are provided. The directional strip is indeed permeable to air. In this way, however, only diffusion is possible in that ascending, warmer ones Air escapes when there is no wind and thus ensures ventilation. Of course you can "Pressed in" air can also escape in the eaves area of the roof but not the normal case. These types of ventilation are now only passive ventilation, the effect of which is inadequate. One for them Active ventilation required suction effect in the ridge or ridge area can this ventilation element does not arise.

On the other hand, recycling of the materials used proves to be extremely difficult. If such recycling is not possible, then remain only as landfill alternatives or if necessary after elaborate separation a combustion with the associated consequential loads. However, this is not desirable for environmental reasons. Furthermore, such are Sealing strips only for specified ridge and / or ridge slat widths manufactured.

From DE-U 92 09 275 a ridge breather element is known. The known Burr venting element consists of a rigid plastic and has one trapezoidal cross-sectional shape. To adapt to roofing slabs are along longitudinal edges of foam sealing strips at the bottom of the Ridge breather element attached. This well-known ridge ventilation element first has the disadvantage that it is not rollable and consequently one requires large transport space and is difficult to move. Another disadvantage is that the ridge venting element only by its rigid construction can be used for roofs with a certain pitch. For roofs Different roof pitches must have different burr ventilation elements getting produced. For a roof with two sides of the ridge different A special ridge ventilation element would even be required for the roof pitch. Added to this is the disadvantage of multi-part training, the disposal difficult.

The invention is therefore based on the object of a sealing strip to create the type mentioned, avoiding the aforementioned Disadvantages uses the advantages of known ventilation elements, but simple manufactured inexpensively and on ridge and / or ridge panels different widths can be set.

This object is solved by the features of claim 1. Of the Sealing strip according to the invention is rollable and made in one piece. He is therefore inexpensive to produce from only one material and is easy disposable or recyclable.

The sealing strip according to the invention has a central area, which for Edition on a ridge and / or ridge plate is determined. To the middle area join with the central area one-piece side strips, which from a plastically deformable material and thus to the top of Roofing sheets are customizable. These side stripes include one section laterally adjoining the central area, which is part of the width the side strip occupies, as well as the side that adjoins this section on the outside Edge strips. The one between the middle area and the edge strip arranged section and the edge strips are part of the side strips. The Edge strips bridge a gap between roofing tiles and adjacent cover elements sealing. The fact that such an edge strip is arranged on both sides of the weather strip, there is a complete Sealing of the sub-roof area from roof side to roof side. Act the roof covering used is a "beaver" roof covering, so edge pleating is preferably omitted and it becomes an optimal seal a smooth edge strip is used.

In the between the central area of the weather strip according to the invention and the edge strip arranged section are ventilation openings appropriate. The ventilation openings cause cross winds due to outside air an active ventilation of the roof interior below of the weather strip. The air passing over the sealing strip sucks air from the roof interior below through the ventilation openings. So on hot summer days there is always good and quick heat dissipation and on cold and rainy days a safe removal of moisture in the Ventilation gap provided below the ridge caps. Another advantage of The sealing strip according to the invention is easy to adapt different ridge and / or ridge slat widths. The weather strip is thus diverse both for roofs with ridge and / or ridge battens of different widths as well as for roofs with different roof pitches.

The sealing strip preferably consists of metal as a plastically deformable material. Because of the use of metal is on difficult to recycle plastics. So that's it Possibility of complete recycling. Consequential charges, that occur when using plastics, brings the sealing strip according to the invention no longer with yourself. Furthermore, metals are not combustible, what however, this is the case with the known PP nonwovens. Corresponding there are hardly any here in the event of a fire toxic substances on what effects on the environment could have.

In training it is provided that it Metal is about lead. Likewise, one use is of tin or copper possible. Such a weather strip is extremely resistant, so that hardly any material rotting occurs. Also by UV radiation, in particular due to increasing UV radiation, the weather strip becomes not attacked, so the lifespan compared to conventional sealing strips Plastic increased. The durability can be in the range the 30-year guarantee that brick manufacturers on their Give bricks, lie. When using lead sheet is also for the entire weather strip for an ideal adaptation to any brick or pan shape etc., because lead is dimensionally stable, but rollable and can be optimally adapted to the shape of the roofing slabs is. Lead is extremely supple and can therefore also have very deep troughs Compensate for the roof covering. It is not an adhesive more in the edge area, such as glue, is necessary. Accordingly, the work step in which one Adhesive layer on the underside of the weather strip must be applied.

If the lead is coated, the first is: additional corrosion protection, second can be used a red, brown or anthracite colored coating each corresponding to the color of the brick Surface can be used. If the lead is tinned, so The tin plating ensures that no lead carbonate got into the sewage.

To over the entire weather strip for optimal Ensuring water drainage is the central area and preferably also the side strips are corrugated. The wave or pleating valleys formed in this way then serve as water drainage channels. At the same time shows the sealing strip due to this training a high stretchability and can therefore be done by hand can be adapted to any brick shape. Furthermore are due to this design for the ridge area necessary overflow channels for roof ventilation guaranteed. Instead of a wavy one Pleating for the middle area and / or the side stripes can also be provided that the central area and / or the side strips are smooth. At a pleating of median strips and / or side strips is also a different version than one wavy pleating possible. For example the pleating is also sharp-edged in the form of a zigzag line be trained or angular with itself periodically repeating, rectangular course. The Edges of the angular or sharp-edged version can but also rounded off with small radii on the Edges be formed.

The side stripes are preferred for training an edge strip with a longitudinal break Mistake. One facing the central area Section of the hard shoulder can also be without Break breaks into a border strip.

Due to the training in the form of a longitudinal bead trained interruptions result for the sealing strip Areas with a spoiler-like effect. In the case of forced convection, the Cross-wind air flowing in from outside in the area of this Interruptions, especially due to the following "Bulging" of the pleating, swirling and so on prevented from flowing in, while such an effect in Do not flow out on the opposite sloping roof he follows. This leads to a slight negative pressure in the Space between the weather strip and the ridge cap, which is advantageous on the Current from the roof building affects. For this is the arranged between median strips and marginal strips Section of the side strips with ventilation openings Mistake.

In a preferred embodiment it is provided that the through the middle area and the side and edge strips formed sealing strips a total width between Can have 150 to 400 mm. The total width of the Sealing strip is only by the width the verge determines while the middle area as well as the section between the verge and the central area one for sealing strips of different overall width have constant width. Accordingly, it is possible, for example To produce sealing strips of the greatest overall width, in which case the Edge strips can be shortened to the desired width. this will the manufacturing process also different for sealing strips Overall width simplified.

In one embodiment of the invention, the central area of the Sealing strip in the side strips over at least two longitudinal, beads each having a section of a predetermined length about. Because of this design, the weather strip has preformed Bend edges, which each have different ridge and / or ridge slat widths are customizable. Accordingly, for different ridge and / or burr slats, only a sealing strip is produced, whereby the manufacturing process is both simplified and can be done more cheaply. For example, the beads and sections be designed in such a way that they match the ridge slat widths of known ridge slats from 3 or 5 cm. The adjacent beads are then 10 mm apart from each other.

The fact that the ventilation openings each have a shape a bulge formed edge or an edge will have the interruptions close to the edge turbulence generated with forced convection still elevated. With free thermal convection without cross wind can flow out of the roof into the flow space Flow air out on both sides. Rain or condensation as well as any water that may have been driven in Valleys of the pleats led outwards. A Penetration of water, for example by driving rain, is due to the break in the edge area as well as the Edge of the ventilation openings severely obstructed. Because of of these configurations is an active ventilation in Ridge area possible. There is a suction effect in the Ridge area below the ridge tile or stone or in the ridge area below the ridge tile or stone in the presence of wind, so that quasi a forced Ventilation or convection occurs. The suction effect on the one hand results from the fact that on the lee side of the roof in the wind due to the breaking of the wind flow A vacuum zone is created at the ridge, into which air enters from the area below the ridge tile or stone is pulled. On the edges or edges of the ventilation openings creates the aforementioned air turbulence through which it is possible that both on the windward and on the Lee side forced the vent over the ridge area becomes. Such edges or edges or bulges are missing at the ventilation openings, as in the case of the State of the art ventilation elements the case is, there is no air turbulence, and thus results even a relatively weak suction effect, through which active ventilation on both sides is impaired.

In a preferred embodiment, the ventilation openings run perpendicular to the longitudinal beads, wherein they extend essentially over the length of the wave crests of the section arranged between the central and edge strips. It is preferably provided that each wave crest is provided with a ventilation opening. Due to the arrangement of the ventilation openings in the transverse direction of the sealing strip, an undesired entry of water / snow into the roof is almost impossible. Due to the arrangement of the ventilation openings in each wave crest, they are so numerous that a ventilation cross-section of up to 320 cm ² / m (cm ² / m) can be achieved. As a result, DIN 4108 (3) is more than fully met.

In a second preferred embodiment, the Ventilation openings in the form of openings in bulges arranged. The bulges preferably point one revolving around the wave crests Edge on. These bulges are no longer there Components of the wave crests, but separately opposite trained this. Furthermore, due to the rotating Edge as well as the bulges of rain or condensation not in the openings and so in the roof penetration. The ventilation openings can be round, be square or oval, with the latter a ratio of about 2: 1 between the width of the Ventilation openings appear optimal for their length. The choice of ventilation openings depends on the desired air flow to be achieved. The Breakthroughs in the bulges can be done easily can be obtained by punching out. The stability of the However, this does not result in any sealing strip Way decreased.

Overall, this is a weather strip created, which due to the material used and its UV stability is extremely long-lasting is very easy and with little Laying time can be attached to the roof of a house can. Furthermore, such is according to the invention Sealing strips provide optimal active ventilation given in the ridge or ridge area.
