Description

The invention relates to a sealing strip for ridge and / or Burr covers made of an air-permeable, foamed Plastic with its central area on a Ridge plank and with its edge areas on adjacent Roof slabs can be placed on sloping ceilings is.

Such a sealing strip is from DE 39 05 142 A1 known.

The purpose of this weather strip is to separate the Ridge plank and the right and longitudinal ridge remaining roof coverings on the left Seal gap at least so far that penetration rainwater, flying snow, vermin or debris in the roof interior is avoided as much as possible. At the same time but the weather strip should be a sufficient find Allow ventilation of the roof interior to the roof structure protect against damage caused by rot.

This is the case with the sealing strip according to DE 39 05 142 A1 achieved in that a cross-section essentially rectangular weatherstrip on the bottom has an approximately V-shaped recess, with this Recess is placed on the ridge screed. The two flanks created by the V-shaped recess are sufficient up to the roof covering panels of the respective sloping roof and thus cover the gap between the ridge plank and the Sloping ceilings. On such weather strips the ridge tiles put on and exert a force on the Sealing strips so that this is in its upper Area of the contour of the ridge tile and in its lower Adjusts the area of the contour of the roofing panels flush. This ensures that the weather strip strips the gap between the ridge tile and the weather strip and the Gap between the roofing and the Seal strips securely closed. The entire cavity between the ridge tile and the respective one The roof slabs of the sloping roof is through the Weatherstrip filled.

The sealing strip made of the foamed plastic is permeable to air, so that from the roof interior rising air through the open-celled pores of the foamed Plastic can escape into the open. Due to the current conditions of the roof truss The wind helps the air to escape from the interior of the roof.

An essential feature of the known sealing strip is in that this sealing strip is very dimensionally stable is. The sealing strip is made of a dimensionally stable, foamed Made of plastic and the shape stability still increased in that the cross section of the weather strip is irregularly formed. The well-known sealing strip requires a large storage and transport space.

EP 0 117 391 A2 describes a hard plastic Ridge or ridge cover known, the sealing strips is arranged below the ridge tile and the Gap between the ridge screed and the adjacent ones Covers sloping ceilings. This sealing strip settles from a central area lying on the ridge screed, adjoining ventilation areas arranged above the gap and adjoining the ventilation area, made of an elastically formable material, comb-like teeth having edge area together. With spacers arranged above the ventilation area the sealing strip is spaced from the ridge tile, so that there is a flow zone under the ridge tile trains. Through openings provided in the ventilation areas the air from the roof interior into the flow zones climb up and from there is one across to the ridge of the roof current wind flow transported away.

From a brochure by Klöber, May 1994, is one Ridge cover known from a reinforced, water-repellent PP fleece with a wave profile is made. This Ridge cover is also on with its central area the ridge board is placed on and extends up to the respective roof covering panels arranged on the sloping ceilings and thus covers the gap between the ridge plank and the sloping ceilings. Then on this ridge cover the ridge tiles placed in such a way that between the ridge cover and the ridge tile a flow zone trains. In the middle of this ridge cover are Openings are provided that allow the air from inside the Roof structure allows to ascend into the flow zone. The one above the gap between the ridge screed and the roof slopes arranged area of the ridge cover consists of several layers of a flat fleece arranged one above the other. These flat nonwovens are only partially permeable to air, so that the ventilation of the roof interior essentially over the pleated structured middle area with his Ventilation openings. For the ingress of snow or Preventing dirt is another one on the central area Fleece layer put on.

The ridge cover from Klöber can be used as an endless belt Roll up lengthways and is therefore easy to store and to transport.

This well-known ridge cover is made of several layers of fleece composed, has an additional in the central area Protective layer made of fleece and is in the edge areas with an additional, water-repellent Provide protective layer.

Proceeding from this, the invention is based on an object a sealing strip of the type mentioned to further develop that this sealing strip improved Shape adaptation to the contours in the ridge area and yet at the same time the advantages of an open-pore one Foam uses.

This object is achieved in that the Sealing strips of the type mentioned above is further developed that the sealing strip in his The central area is deformed into a solidified central path, that the weather strip solidified in its peripheral areas Edge strip is deformed, which is a wrinkle-shaped Show structure and that between the solidified middle course and the solidified edge strips open-pored ventilation areas are trained.

A sealing strip designed in this way has the advantage that it is made from a single material and therefore very inexpensive can be produced. Such a weather strip can also be used can be made up as an endless strip, the laying on the construction site is significantly simplified because the recurring, complicated preparation and adjustment of others Sealing strips are omitted.

Another advantage of the sealing strip according to the invention is that the solidified middle course in contrast to the ventilation area is not dimensionally stable. This can the sealing strip when installing a predetermined Adjust the contour, especially the inclination of the roof structure and yet in a flat or even orientation stored and transported rolled up.

In addition, the inventive design of the Sealing strip ensures that the ventilation area continues from a dimensionally stable, air-permeable and foamed Plastic is there, which is able to close the gap between to span the ridge screed and the sloping ceilings, without changing its external shape. The middle course, however consists of a foamed compressed by compression Plastic that is no longer dimensionally stable. The Edge strips are, at least if they are wrinkled Have structure, in the direction transverse to the ridge essentially dimensionally stable and in the direction of the roof ridge unstable.

This will cause the weather strip to move as soon as it hits the Ridge plank is placed on the outer shape of the ridge and adjust the adjoining roof slopes. That is, the Edge strips are due to their own weight on the Sloping ceilings fall because the central web is unstable and the adjacent outwardly projecting strip areas are not protruding can keep from the roofing tiles. The ventilation areas are from the wrinkled edge strips in one level with the verge because the ventilation areas and the edge strips are dimensionally stable across the ridge of the roof are.

It follows that the ventilation areas together with the edge strips have a slope that the roof slopes of the roof structure essentially corresponds.

In a special embodiment, the edge strips are of the weatherstrip folded in a wave-like manner.

This wave-like fold, which is also called a pleated skirt Structure can have the advantage that the Edge strips in the longitudinal direction of the ridge due to Simply let the pre-folded crease edges squeeze together. Furthermore can be formed in such a way Pull apart the longitudinal direction of the ridge in a simple manner. When pulling apart, the increases relative angles of adjacent folds or flanks and it this section of the edge strip extends without it Material stresses occur.

This ensures that the edge strips on the The contour of the roofing slabs below it is flush nestle and the gap between the ridge and the Closing roofing panels reliably without Edge streak a transverse distortion occurs.

In a particularly preferred embodiment of the invention Sealing strips are the edge strips a portion of their facing the roofing slabs Apply adhesive, preferably hot glue, to the side.

This allows the weather strip to be placed on the roof covering panels be glued and thus ensures the permanent tight sealing of the gap between the ridge screed and the sloping ceilings.

The use of hot glue is advantageous because in Summer on the roof and especially on the roofing slabs, extremely high temperatures can occur and the hot glue ensures that even under these conditions the adhesive bond does not break.

Another advantage of hot glue is that this is inseparable from the solidified plastic of the sealing strip connects.

This has the advantage that the adhesive is definitely on Sealing strip remains and not accidentally during assembly together with the protective layer from the weather strip can be deducted.

In another preferred embodiment of the invention Sealing strip is the transition of the middle web heel-shaped to the ventilation area. This will achieved that the sealing strip even in the most varied Slopes of ventilation areas well adapted to the Ridge board rests.

The ridge plank is usually rectangular in cross section Wooden beams and the central panel, usually the same The width of this wooden beam lies on it on. In order to avoid that the middle course over the Wooden beams protrude or that the middle path is incomplete on the wooden beam, the contour of the Sealing strip in the relevant area to the contour the ridge screed be complementary. This is through training a paragraph in the transition from the central panel to the ventilation area guaranteed.

In yet another embodiment, the ventilation area on its side facing the central web and, at least on the side of the weatherstrip facing the ridge plank rounded.

This has the advantage that the weather strip after it was placed on the ridge plank, a little freedom of movement remains so that the ventilation areas with the adjoining edge strips according to the slope can angle the sloping roof without the foamed Plastic of the ventilation area is deformed.

Another advantage of the rounded ventilation area is in that the sealing strip is itself a leader becomes. That means that if, for example, it becomes a role wound sealing strips at one end of the ridge plank is put on and the roofer then this role rolls on the ridge board that the sealing strip then constantly (without the roofer's intervention) into the desired one Rolls out on the ridge screed, because the rounded edges of the ventilation area, if necessary in cooperation with a suitably dimensioned Center panel, a guide form the weather strip. This facilitates the assembly of the sealing strip according to the invention. Under the ridge tiles and over the weather strip is a free space through which a very simple and effective ventilation of the roof interior, is possible even when there is no wind. The one from the roof interior Exhaust air rises through the ventilation area of the Sealing strip through into the free space above. The wind hitting the roof truss is partially through the windward opening between the sealing strip and the ridge tile in the free space and occurs the leeward roof side out of this and takes on the one hand, the exhaust air in the free space with and on the other hand, sucks in additional exhaust air from the roof interior above. The other flowing over the ridge tiles or ridge stones Wind creates a negative pressure on the leeward side, which creates the suction effect reinforced under the ridge tile. This will causes the air both from the free space as well as from is sucked out into the roof interior. When there is no wind the exhaust air from the roof interior rises due to the Thermal upwards into the free space and then flows into the open. The free space thus forms a flow zone above the sealing strip and ensures in any case good ventilation of the roof interior.

In a special embodiment of the invention Sealing strips are the middle web and / or the edge strips about 0.5 to 5 mm, preferably 2 mm thick, whereas the ventilation area about 0.5 to 5 cm, preferably 2 cm is thick.

This ensures that the weather strip as a whole remains highly deformable that it can be rolled up and so that it is light and easy to store and carry.

In a further preferred embodiment, the sealing strip is in cross section symmetrical to the longitudinal axis of the Ridge trained. This enables an even easier one Storage of the sealing strips.

In a preferred embodiment, the weather strip is designed to be rolled up.

This has the advantage that the sealing strip is closed larger rolls that can be rolled up very easily and stored and transported inexpensively and without great effort can be brought to the ridge of the roof. A such a roll has a length of, for example, 5 to 20 meters. This length is sufficient for a normal roof and can still be easily carried by the roofer.

The arrangement of the ventilation area directly above the gap between the ridge screed and the adjoining roof slopes has the advantage that the inflowing from the roof interior Overcoming air without detours and without great flow resistance to have to get outside through the ventilation area can.

It is not a sealing strip according to the invention absolutely necessary that the edge strip exactly over the Roofing tiles is arranged. He can also use the Roof covering plates extend into the gap, without the advantages of the sealing strip according to the invention to diminish.

The use of a foamed plastic with three-dimensional Lattice structure in a sealing strip according to the invention, which is also dimensionally stable but compressible and open-pored has the advantage that the sealing strip becomes very breathable, light and can be rolled up.

In a further embodiment of the invention Sealing strips take the lattice webs of the lattice structure of the foaming plastic a space of about 1% to 10 % of the volume of the foamed plastic on. The pore size of the foamed plastic is Range between 8 and 80 ppi (pores per inch), taking it it is not necessary that all pores of a weather strip have the same size. Rather, it can also happen that there are pores of different sizes in a sealing strip, which, however, range from 8 to 80 ppi.

This has the advantage that the foamed plastic in the ventilation area is very permeable to air and still ensures that no flying snow, no leaves, no insects or other debris in the gap between the ridge plank and can reach the sloping ceilings.

A hydrophobic design of the plastic has the advantage that water drops, water vapor or flying snow, the sits on the weather strip, not picked up by it , but rolls off the weather strip and thus cannot get inside the roof.

A hydrolysis-resistant design of the plastic Sealing strip has the advantage that the sealing strip has a long service life because the attacking water Plastic cannot decompose.

The use of UV stabilizers increases weather resistance of the plastic and thus the life of the sealing strip.

A non-flammable design of the plastic is used the safety of residents.

In a particularly preferred embodiment of the invention Sealing strip is made of a soft foam with open pores or cells, especially from Polyurethane, polyether, polyvenyl chloride, phenolic resin, soft PVC, Aminoplasts or other foamable plastics made.

For the production of the sealing strip according to the invention is essentially a one from foamed plastic rectangular cross-section sealing strips made, then in its central area and / or in its edge areas are so strongly compressed that each Adjacent lattice webs of the lattice structure to one another apply, the plastic deforms plastically and remains in this compressed state. This will a thin, leather-like middle panel and on the side of the sealing strip thin, leather-like edge strips created.

This method has the advantage that the invention Sealing strips made in a continuous process can be.

In a further embodiment of the manufacturing process become the center panel and the edge areas of the weather strip thermally pressed.

Pressing the plastic while adding heat has the advantage that the plastic deformation of the plastic achieved faster and becomes more permanent.

In a further step, the edge strips formed like a pleated skirt.

That the edge areas simultaneously with the thermal pressing be pleated skirt-like and that the middle area processed simultaneously with the marginal areas , lowers the manufacturing cost of the invention Sealing strip, since the sealing strip is now in one Operation can be completed.

In a further process step, the sub-area of the pleated skirt-like edge strip that the Roof covering plates opposite, a hot glue applied.

The individual figures of the drawing show the invention Partly not to scale. Things of the individual figures are partially greatly enlarged, shown schematically and simplified, so their structure can be shown better.

Figures 1 and 2 show a weather strip according to the invention 10 with a central web 12, one each in the ridge direction to the right and left to the middle track 12 Ventilation area 14, 16 and one each edge strips adjoining each ventilation area 14, 16 18, 20. The transition from the middle track 12 to the ventilation area 14, 16 is hinge-like.

The edge strips 18, 20 have a fold-like structure on, d. that is, they are pleated and everyone Edge strips 18, 20 are composed of a large number of one another connected flanks 22 together, two each Flanks 22 connected to one another via a folded edge 24 are.

The sealing strip 10 is made of a single material, namely made of soft foam. With the one used here Soft foam is foamed Polyether that has a three-dimensional lattice structure. The polyether foam is dimensionally stable but flexible, i.e. that the polyether foam always returns to its original shape, after it has been mechanically deformed. Only when the If polyether foam is plastically deformed, it retains it molded shape.

The polyether foam used here is also at the same time flexible so that the weather strip 10 in a simple manner can be rolled up, as shown in Fig. 1.

Fig. 3 shows a partial section of the invention Sealing strip 10 viewed from the side. Detected here it is clear that in the individual folds of the marginal strips 18, 20 an adhesive 24 is arranged. This adhesive 24 is a hot glue that is very heat-resistant, i.e. it has Sufficient adhesive effect even at high temperatures. To protect against contamination, the adhesive 24 is with a Protective film 25 provided during the assembly of the weather strip 10 can be easily removed. Of the Adhesive 24 is already on the at high temperatures solidified edge strips 18, 20 applied so that the Adhesive 24 with the plastic an inseparable connection comes in. The edge strip 18, 20 can be of a flexible Metal strips. The metal strip can too be inserted in the edge strip.

The adhesive 24 and the protective film 25 are in the others Figures not shown for the sake of clarity.

Fig. 4 shows a partial section of the soft foam the ventilation area 14 according to line IV in Fig. 2. The soft foam has a three-dimensional lattice structure 26 on, in which the individual lattice webs 28 together are connected to create cavities 30. The lattice structure 26 of the soft foam is only simplified in FIG. 4 and shown schematically.

In the embodiment according to the invention, that of the Lattice webs 28 of the lattice structure 26 take up space approximately 2.5% to 3% of the total of the flexible foam Volume. The pore size of the flexible foam is 35 ppi to 60 ppi (pores per inch) (1 inch = 2.54 cm), i.e. the ventilation area 14, 16 can be made of a soft foam, for example exist, which only has pores of size 35 ppi or also consist of a soft foam, the pores different sizes in the range from 35 ppi to 60 ppi having. The larger the number of pores per inch, the larger is also the air resistance of the ventilation area 14, 16.

The soft foam used in the sealing strip 10 contains Portions of material that make it non-flammable.

Stabilizers are also added to the flexible foam, so that the weather strip 10 is particularly weatherproof is (UV stabilizers).

The soft foam used here is an open-cell or open-pore soft foam, through which air and water can penetrate. The flexible foam itself is hydrophobic, i.e. it takes the water does not appear, but repels it. The water runs off the sealing strip 10 and drips on the underlying roofing slabs 32.

In addition, the soft foam used is resistant to hydrolysis, so that the water that occurs is the flexible foam does not attack or decompose and therefore has a long service life of the sealing strip 10 is reached.

In other embodiments, not shown, the Sealing strip 10 also made of a soft foam on the Basis of polyurethane, polyvinyl chloride, phenolic resin, soft PVC, Aminoplasts or the like. Be produced.

FIGS. 5 and 6 show the sealing strip 10 in accordance with Fig. 1, such as in the ridge area of a roof truss is arranged.

The sealing strip 10 lies with its central path 12 on a ridge board 34. The ventilation areas 14, 16 cover the gap between the ridge board 34 and the the roof slabs 32 Edge strips 18, 20 lie on the roof covering plates 32 flush on and are over one on the bottom of the edge strips 18, 20 arranged adhesive 24 glued to this. The wave-like folding of the edge strips 18, 20 enables that the edge strips 18, 20 along the ridge screed 34 squeeze a little in a simple way or pull apart. This ensures that the edge strips 18, 20 of the outer contour of the roofing panels 32 adjust and unwanted openings or gaps be avoided. Wave valleys and wave crests of the roofing slabs become completely flush from the margins covered.

Because the sealing strip 10 can be rolled up, the Assembly of the sealing strips 10 on the ridge in simple Way. The sealing strip 10 only needs placed on the ridge board 34 with its central track 12 and unrolled along the ridge board 34.

The step-like transition from the middle path causes 12 to the ventilation area 14, 16 and / or the rounded training the ventilation area 14, 16 that the sealing strip 10 is self-managing.

As soon as the sealing strip is unrolled, the Ventilation area 14, 16 due to the weight of the weather strip 10 quasi independently over the gap between the ridge plank 34 and the roofing panels 32 and the Edge strips 18, 20 lie on the upper end of the roofing panels 32. Now you only need the protective film Remove 25 of the adhesive 24 and the edge strips 18, 20 are glued to the roofing panels 32.

The ventilation areas 14, 16 and the edge strips 18, 20 fit in a simple way to the contour, especially the Inclination of the roof surfaces, because the central track (12) is articulated is connected to the ventilation areas 14, 16.

After the sealing strip 10 has been installed Ridge or ridge tiles or the ridge or ridge stones 38 put on. The one between the ridge tiles 38 and the sealing strip 10 remaining free space 40 forms a flow or air access zone for those from the roof interior rising air and for the air flowing across the roof ridge Air flow.

In this free space 40 that collects from the interior of the roof exhaust air rising through the ventilation areas 14, 16 and passes through the between the weather strip 10 and the Ridge tile 38 located ventilation gap 42 to the outside.

The airflow arriving on the windward side 44 of the roof partially flows through the ventilation gap 42 into the free space 40 in and flows out of the ventilation gap 43 on the leeward side 46 out again and takes it in the free space 40 existing exhaust air with. Other parts of the air flow are directed over the ridge tile 38 and generate on the Leeseite 46 a negative pressure, which in turn is in the free space 40 sucks off air through the ventilation gap 43, so that good ventilation of the roof interior is guaranteed is.

For ventilation of the roof interior, it is advantageous if the air flow in the free space 40 is transverse to the ridge longitudinal direction he follows. With the sealing strip according to the invention 10 this cross flow of air is achieved by that the wave-like folded edge strips 18, 20, which form the underside of the ventilation gaps 42 and 43 which Air flowing in and out transversely to the longitudinal direction of the roof ridge align.

The generated by the flanks 22 of the edge strips 18, 20 Channels do not leave you transverse to the ridge longitudinal direction swirling flow and only the component continue to flow across the roof ridge longitudinal direction with low resistance, so that below the ridge tile 38 a substantially Air flow running transversely to the roof ridge longitudinal direction prevails.
