Abstract

The roof-ridge-sealing strip has a central air-permeable zone (8) of fabric structure, and two edge areas (9) adaptable to the corrugations of the tiles by stretchable stabilising inlay(s) of metal or other material. The strip is in one piece of fabric extends for the full width, and is extensible in the lengthwise direction at least at the edge areas. The inlay has undulating wires or strips running parallel to the edge (10'), and which are secured to the fabric surface in a holder allowing variation of the undulating pattern.

Description

The invention relates to a ridge sealing strip according to the preamble of claim 1.

A generic ridge sealing strip is known from DE 40 01 766. The ridge strip for ridge or ridge ventilation known from there consists entirely of a fleece or a fabric, which makes it light in weight, inexpensive to manufacture and, because it can be rolled up in longer webs, easy to process. The longitudinal edges exposed to the weather are water-repellent or watertight, so that at least the central part not exposed to the weather is permeable to air. A corrugation is formed in this fleece or fabric on the free edges of the side parts, which makes this fleece or fabric conformable and, supported by adhesive cords arranged on the underside on the outer free edge as a stretchable stabilizing insert, can be molded onto any roof tile contours.

In the prior art EP 0 117 391 also discloses a ridge or ridge cover for roofs covered with roofing panels. This cover consists of a rigid middle part made of hard PVC with laterally comb-like elastic fingers, which are covered with an air-permeable material that is profiled in a wave shape. Holes are formed in the rigid middle part, which make it permeable to air.

From EP 341 343 a ridge or ridge ventilation element is known, with a central strip intended for resting on a ridge or ridge plank and allowing air to pass through, and with adjacent side strips which can be adapted at least with their outer longitudinal edges to the top of roof covering panels. The median strip has an air-permeable, water-repellent and snow-resistant fleece, and the side strips each consist of soft, stretchable film strips in which a plastically deformable expanded metal grid is embedded.

The invention has for its object to improve the ventilation of the ridge batten in a generic ridge strip.

The object is achieved by the invention specified in claim 1. The subclaims represent advantageous developments.

As a result of the configuration according to the invention, air passage channels extending transversely to the ridge screed extension are formed, so that the air passing transversely to the ridge screed extension through the air passage channels can absorb the moisture directly on the ridge screed surface in order to remove it by convection.

As a result of the further embodiment, according to which the two edge strips are connected at a distance by a central connecting strip, there is a solution which is more favorable in terms of handling. Due to this multi-part nature of the ridge sealing strip, the latter lies down after being fixed on the ridge plate in the area of the middle connecting strip without an external one It acts lightly on the roof covering panels, which means that they can be molded and fixed to the latter without pretensioning the ridge sealing strip. The middle connecting strip is designed as a 30-50 mm, preferably 40 mm wide and 150-250 g / m², preferably 190 g / m² solid fleece. The overlapping zone in the area of the connection between the connecting strip and an edge strip has a width of 10-20 mm, preferably 15 mm. The installation of a ridge sealing strip designed in this way is carried out in the simplest way, in that the latter is fixed in the region of its central connecting strip on the ridge batten, for example by means of nails, and after the protective film of the self-adhesive layer has been removed, is molded and glued to the roof covering plates. In an advantageous development, it is provided that the overlapping connection zone has air passage channels lying in the width direction. The latter result from the multi-part structure of the ridge sealing strip and ensure constant ventilation of the ridge batten, in contrast to the previously known ridge sealing strips, which cover the entire upper longitudinal surface of the ridge batten without any ventilation, which means that insect and fungus infestation is foreseeable due to the excessive moisture content of the ridge batten is, a moisture content of the ridge slat of less than 20% is guaranteed in the inventive design of the ridge sealing strip with air passage channels. Insect and fungal attack is thus successfully counteracted. The air passage channels can be obtained from a linear arrangement of the wave crests of the longitudinally corrugated edge strip with the connecting strip running smoothly. The design can be such that the middle, smooth connecting strip is glued on the underside to the wave crests of the edge strips which are cross-corrugated in the longitudinal direction. The air passage channels for ventilation of the ridge plate thus result in the area of the wave troughs. The width of the connecting strip corresponds approximately to the width of a ridge batten, with which optimal ventilation of the latter is achieved. Furthermore, there is the advantage that the cover cap fixed above the ridge covering strip on the ridge batten is padded in the corner regions of the ridge batten on the one hand by the corrugated edge strip and on the other hand by the middle connecting strip having the width of the ridge batten. An advantageous further development is that the connecting strip is adhesive-coated on its underside. As a result, the ridge covering strip can be pre-fixed in the simplest way by hammering on the ridge batten. Clamping or nailing in this area therefore only takes place after the ridge covering strip has been completely laid or is completely omitted, since the fastening means, for example nails, of the covering caps achieve a desired additional fastening of the sealing strip. The adhesive coating has a further advantage with regard to the handling and laying of the ridge cover strip, since it can be easily lifted off the ridge plate and its position changed if the ridge cover strip has to be aligned. Furthermore, it is provided that the connecting strip rests on the top of the edge strips and that the edge strips on the underside, near the outer longitudinal edges, have adhesive beads for adhesion to the roof covering panels. Such a self-adhesive layer, for example made of plastic, enables the outer longitudinal edges of the ridge sealing strip to be optimally fixed on the roof covering panels. When the ridge sealing strip is delivered, the adhesive beads can be provided with a continuous protective film. This ensures optimal sealing of the roof interior against rain and flying snow. Advantageously, in order to improve the adaptation of the ridge sealing strip to the roof covering plates due to a meandering course of a wire, stretchable stabilizing inserts can be provided, which are attached to the edge strips via the adhesive beads in such a way that the adhesive beads fully embed the wire and a width of 10-20 mm, preferably 15 mm. The adhesive beads thus fulfill a double function, namely as a holder for the stabilizing insert and after removing the protective films as an additional seal after laying and pressing the ridge sealing strip onto the top of the roof covering panels. In a preferred embodiment, the meandering course of the wire can be designed in the same direction as the wave course of the edge strip. This makes it possible to corrugate both the fleece and the stabilizing wire in one operation, after which operation another one can immediately attach to apply the adhesive beads. This solution, which has been optimized in terms of production technology, also offers the advantage that, due to the corrugation of the wire in the same direction to the edge strip, the provision of the corrugation of the edge strip is blocked when shrinking. The corrugation of the edge strip is stabilized by the fixations in the area of the center strip and by the wire embedded in the adhesive bead, which ensures that the ridge cover strip can be rolled up optimally. In order to make the stabilizing insert highly stretchable when adapting to the roofing panels, it is intended to embed the wire so that it can tip over into the adhesive beads. When pressed against the roof covering plates, the wire having the wave shape tilts inside the adhesive bead into a position aligned parallel to the surface of the edge strip. The meandering curved wire is therefore highly stretchable and offers an optimal adaptation of the ridge sealing strip to the wave shape of the installed roof covering panels. The connecting strip can advantageously have bumps on its underside on its central longitudinal line made of compressible material as ridge fixing points. In a preferred embodiment, these bumps can consist of adhesive material and have a film cover on their top. As a result, the ridge sealing strip can be at least pre-fixed in the area of its connecting strip by means of the bumps on the ridge batten that are evenly spaced from one another. This is done in the simplest way by means of thumb pressure in the hump, the compressible material spreading beyond the surface of the film covering and thereby connecting the sealing strip to the ridge slat. Now that the entire ridge sealing strip has been aligned, nailing or the like can take place in the region of the compressed bumps. If the humps have strong adhesive material, these are sufficient to fix the ridge sealing strip to the ridge batten. The sealing of the roof interior against rain or flying snow is optimized in that the top of the edge strips have an elastic protective layer that extends from the outer edge to about the middle of the respective edge strip. Due to this design, the interior of the roof is also resistant to rising damp from the roofing panels protected. This elastic protective layer preferably has a color which corresponds to that of the roof covering panels and the covering caps, in order to achieve an optically positive effect of the ridge area here as well.

It is also conceivable to provide a ridge sealing strip according to the invention with longitudinal fold lines at a distance from the longitudinal center line of the sealing strip. The distance to the longitudinal center line is approximately 25-35 mm, preferably 30 mm. This measure prevents a tendency of the ridge sealing strip to reset after being glued to the roof covering panels, for example if they are dirty. There are thus predetermined folding lines which give the advantage that after the ridge sealing strip has been applied to the ridge panel, the sealing strip almost automatically lies on the roof covering panels. This configuration is also conceivable for ridge sealing strips which have embedded wire mesh areas. In a preferred embodiment it is provided to provide the longitudinal fold lines in the area of the corrugation. The stiffness of the ridge sealing strip which is customary and also desired in this area is specifically prevented by this measure in the form of a predetermined kink. Finally, in a preferred embodiment, the longitudinal buckling lines are achieved by expressing the wave formers up to the height of the wave crests. The fleece of the ridge sealing strip is thus formed in a straight line in this area in the longitudinal extent of the ridge sealing strip. It is particularly advantageous that the factory-rolled ridge sealing strip already has such a predetermined crease line.

It is further provided that the ridge sealing strip has wires or bands which are meandering and corrugated parallel to the edge and which are fastened to the wide surface of the fleece in a holder which enables the meandering to be varied. To produce such a ridge sealing strip, a fleece is only provided in its edge regions with a meandering corrugated wire or tape, the stabilizing insert formed in this way being held on the broad surface of the fleece. There is thus an optimal adaptation of the ridge sealing strip to the wave form of the roofing panels. Due to the simple structure and the low weight of the ridge sealing strip, rolls can be delivered in this form, whereas in contrast to the prior art mentioned, it is not necessary here to cover the ridge sealing strip in its edge areas with a protective layer to be removed before laying Mistake. Because of this configuration, a ridge sealing strip that is simple to manufacture and use is created. To lay such a sealing strip, it is simply rolled out over the ridge screed and fastened there with nails or the like. A self-adhesive layer, which is provided with a protective film on delivery, can advantageously serve to hold the stabilizing insert. This self-adhesive layer thus fulfills a double function, namely as a holder for the stabilizing insert and after removing the protective film as an additional seal after laying and pressing the ridge sealing strip onto the top of the roof covering panels. Such a self-adhesive layer made of rubber and plastic mass allows a variation of the meandering course and thus a stretching of the stabilizing insert. In an advantageous Further development provides that the embedding takes place by means of an adhesive covering only areas of a meander repeat. This can be realized by self-adhesive points, which can be provided with a continuous protective film when the ridge sealing strip is delivered. This point-by-point attachment of the stabilizing insert optimizes the elasticity of the edge areas. A wire which is bent in a meandering manner parallel to the surface of the nonwoven is preferred as the stretchable stabilizing insert. Such a wire is easy to manufacture and is preferably attached point by point in the edge areas of the fleece by means of adhesive. The meandering curved wire is therefore highly stretchable and offers an optimal adaptation of the ridge sealing strip to the wave shape of the installed roof covering panels. Alternatively, the stretchable stabilizing insert can also consist of a band which is corrugated in a meandering shape perpendicular to the surface of the nonwoven. The latter can also be attached point-wise in the edge regions of the sealing strip in the manner already described by means of adhesive. The amplitude is in the range of 1 - 3 cm both when using meandering bent wire and when using corrugated tape. An advantageous further development of the subject matter of the invention is to impregnate partial areas of the nonwoven in order to achieve water resistance with simultaneous air permeability, e.g. B. using acrylic resin. This achieves a roof ventilation with simultaneous sealing against rain and flying snow. According to a further advantageous embodiment, the edge areas of the fleece are needled. The adaptation of the ridge sealing strip to the wave shape of the installed roof covering panels is finally done by one in the edge areas provided longitudinal wave shape of the fleece optimized.

As can be seen from FIG. 1, the ridge sealing strip 1 according to the invention is used to seal the roof interior 2 against rain and flying snow, the structure of the ridge sealing strip 1 being chosen such that ventilation of the roof interior 2 is granted at the same time. The ridge sealing strip 1, for example delivered in the form of a roll, is rolled out on a ridge plank 4 attached to rafters 3 and fastened there, for example by means of nailing. The edge regions of the ridge sealing strip 1 are adapted to the wave shape of roof covering plates 6 suspended on rafter-side roof battens 5. After the ridge sealing strip 1 has been molded onto the roof covering panels 6 a cover cap 7 forming the end of the ridge is placed.

The ridge sealing strip 1 has a central zone 8 in a non-woven structure which allows air to pass through and two needled edge regions 9. The ridge sealing strip 1 is impregnated with acrylic resin in order to achieve a watertightness and at the same time permeability to air.

The ridge sealing strip 1 shown in the first exemplary embodiment according to FIGS. 2 to 8 and in the second exemplary embodiment according to FIGS. 9 to 11 has in its edge regions 9 a wave course of the fleece 10 oriented perpendicular to the surface of the fleece 10 (see FIGS. 3 and 6). The latter is designed to be stretchable in the edge regions 9.

In the edge regions 9, the fleece 10 has a stretchable stabilizing insert S, which runs parallel to the edge 10 ′, in the form of a meandering, corrugated, metallic band 11, the meandering shape of the band 11 corresponding to the course of the corrugated edge region 9 of the fleece 10. The arrangement of the band 11 takes place on the support side of the fleece 10, that is to say on the side facing the roof covering plates 6 (cf. FIG. 5). In order to fasten the tape 11, adhesive spots 12 which are uniformly spaced apart from one another are applied to the support side of the nonwoven 10 and partially surround the tape 11 and thus fix it to the nonwoven 10. The adhesive dots 12 can be formed as self-adhesive rubber or plastic materials, which are covered on the underside of the roof covering panels 6 with a removable protective film (not shown).

Deviating from this embodiment, in the second exemplary embodiment according to FIGS. 9 to 11, the stretchable stabilizing insert S is formed as a metal wire 13 bent in a meandering manner parallel to the surface of the fleece 10. 9, this wire 13 has an amplitude Z of approximately 1 cm. In addition to the wave shape running parallel to the surface of the fleece 10, the wire 13 is adapted to the wave shape in the edge region 9 of the fleece 10 (see FIG. 11). The stretchable stabilizing insert S thus formed is also fixed to the fleece 10 by means of adhesive points 12 on the support side of the ridge sealing strip 1. Due to this configuration, the ridge sealing strip 1 is optimally adapted in its edge regions 9 to the wave shape of the installed roofing panels 6.

In the third exemplary embodiment shown in FIGS. 12 to 14, the fleece 10 has smooth-surface edge regions 9. Here, too, the fleece 10 is in the edge regions 9 on the underside, i.e. H. on the support side, provided with a wire 13 which is bent in a meandering shape and runs parallel to the surface of the fleece 10 and which, as already mentioned, is fixed by means of adhesive dots 12 (cf. FIG. 14).

In all of the exemplary embodiments, the partially embedding of the stretchable stabilizing insert, which is designed either as a meandering wire 13 parallel to the surface of the nonwoven fabric 10 or as a band 11 which is curved in a meandering fashion perpendicular to the surface of the nonwoven fabric 10, by means of adhesive dots 12 in connection with the stretchable edge regions 9 of the nonwoven fabric 10 given an optimal adaptation of the ridge sealing strip 1 to the waveform of the installed roofing panels 6.

The ridge sealing strip 1 is fastened in the area of its middle zone 8 to the top of the ridge plank 4, for example by nailing. After the protective film covering the adhesive dots 12 has been removed, the edge regions 9 which come to rest on the roof covering panels 6 and are provided with the stretchable stabilizing insert are now adapted to the wave shape of the roof covering panels 6. As already mentioned, the adhesive dots 12 used to fasten the stabilizing inserts to the fleece 10 are designed as self-adhesive layers and now also serve to fix the edge regions 9 on the roof covering plates 6.

A continuous ventilation of the roof interior 2 while at the same time achieving watertightness is made possible by the gap remaining between the cover cap 7 and the edge regions 9 of the ridge sealing strip 1 (arrow x).

The ridge sealing strip 1 of the solution according to FIGS. 15 to 29 described below, for example in the form of a roll, is also rolled out on a ridge slat 40 attached to rafters 30 and fixed there. The edge regions of the ridge sealing strip 1 are adapted to the wave shape of roof covering plates 60 suspended on rafter-side roof battens 50. After the ridge sealing strip 1 has been molded onto the roof covering panels 60, a cover cap 70 which forms the end of the ridge is put on.

The ridge sealing strip 1 has two edge strips 90 which are connected to one another by means of a central connecting strip 80 in the form of a fleece. The edge strips 90 which allow air to pass through are designed in a fleece structure and are impregnated with acrylic resin to achieve water resistance and air permeability at the same time. In order to also protect the roof interior 20 against moisture rising against the arrow x in FIG. 15, the top sides 100 of the edge strips 90 are each provided with an elastic protective layer 110 which extends from the outer edge 120 to approximately the center of the edge strip 90. The edge zone formed in this way is designated by A in FIGS. 16 and 20. An optically positive effect of the ridge area is achieved in that the protective layer 110 mentioned has a color which corresponds to that of the roof covering panels 60 and that of the covering cap 70.

The edge strips 90 are connected to one another by means of the connecting strip 80 such that the inner edges 130 of the edge strips 90 lie at a distance from one another which forms a ridge batten ventilation zone B. The connecting strip 80 has a width of 40 to 60 mm, preferably 45 mm, which corresponds approximately to the width of the ridge batten 40, the respective connecting zone C between the connecting strip 80 and an edge strip 90 being approximately 10 mm. Zone D, which allows air to pass through, extends in the central region of the ridge sealing strip 1 between the two edge zones A.

The connecting strip 80 has air passage channels 140 lying in the width direction in the region of its overlapping connecting zones C. These are formed by the linear arrangement of the wave crests of the edge strips 90 which have a wave shape and are oriented perpendicularly to the surface of the edge strips 90 the underside of the smoothly extending connecting strip 80 (see FIGS. 18 and 22).

The edge strips 90 are on their underside, i. H. after the ridge sealing strip 1 has been laid, the side facing the roof covering panels 60 and the connection strip 80 facing away from the outer edge 120, each provided with an adhesive bead 150 for adhesion to the roof covering panels 60. These adhesive beads 150 can be formed as self-adhesive rubber or plastic masses, which are covered on the underside that comes to rest on the roof covering panels 60 with a removable protective film (not shown).

Stretchable stabilizing inserts S, which are each formed in the exemplary embodiment shown in FIGS. 15 to 19 as a metal wire 160 which is bent in a meandering manner parallel to the surface of the edge strip 90, are fastened via these adhesive beads 150. As a result of this configuration, the ridge sealing strip 1 is optimally adapted to the wave shape of the installed roofing panels 6 in the areas of its peripheral edges 120.

In the exemplary embodiment shown in FIGS. 20 to 25, the meandering course of the wire 160 'upon delivery of the ridge sealing strip 1 is in the same direction as the wave course of the edge strip 90. This configuration has the advantage that both the edge strips 90 and the respective wires 160' are simultaneously in one Operation can be rolled, which operation another directly for applying the adhesive beads 150 can follow. Only when an edge strip 90 is pressed against a roof covering plate 60 does it tilt the wire 160 ′ embedded in the adhesive bead 150 in the latter into the position directed parallel to the surface of the edge strip 90 (cf. FIG. 24).

The width of the connecting strip 80 is selected so that it corresponds approximately to that of the ridge batten 40 (see FIG. 19). The underside of the connecting strip 80 of the first embodiment is continuously provided with an adhesive coating, not shown, which serves on the one hand for the connection between the connecting strip 80 and the two edge strips 90 in the region of the connecting zone C and on the other hand a possibility of pre-fixing when laying the ridge sealing strip 1 the ridge 40 represents. By means of this adhesive coating, the ridge sealing strip 1 can be pre-fixed in the simplest way by means of a hammer blow on the ridge batten, with which it is not necessary to use clips or nails. The ridge sealing strip 1 can thus be easily lifted off the ridge batten 40 if necessary, and can be fixed again in a new position. The ridge sealing strip 1 is fixed on the ridge batten 40 by means of the adhesive coating in the region of the ridge batten ventilation zone B, the individual ridge batten fastening points 18 being spaced apart to ensure the desired ridge batten ventilation.

An alternative fixing of the ridge sealing strip 1 on the ridge batten 40 is shown in the further exemplary embodiment. Here, the connecting strip 80 is provided on the underside on its middle longitudinal line with bumps 190 made of compressible material as ridge fixing points 180 (see FIG. 21). These bumps 190 are made of adhesive material and have a foil cover 200 on their top side. The ridge sealing strip 1 is pressed for fixing on the ridge batten 40 only in the area of the bumps 190 by means of thumb pressure against the ridge batten 40 such that the compressible bump 190 swells past the foil cover 200 and on the ridge batten 40 attached (see Fig. 23). Depending on the strength of the adhesive bond, this measure can serve as pre-fixing or as the actual fixing of the ridge sealing strip 1.

Due to the design of the ridge sealing strip 1 in the form of a middle, smooth-surface connecting strip 80, which is connected in the area of two connecting zones C with one edge strip 90 each, in such a way that air passage channels 140 are formed, the ridge sealing strip 1 serves not only to seal the roof interior 20 against rain and flying snow with simultaneous ventilation of the roof interior 20, but also for constant ventilation of the top 170 of the ridge 40, which ensures a moisture content of the ridge 40 of less than 20%. This is particularly important against insect and fungal attack. The air flow for ventilation of the ridge 40 is indicated in FIG. 19 with the arrows y. In order to optimize this ventilation of the ridge batten 40, the ridge sealing strip 1 is only fixed point by point on the ridge beam 40 in the area of its connecting strip 80, either by means of an adhesive coating on the underside of the connecting strip or the hump 190 or by means of nails, staples or the like.

Due to the multi-part design of the ridge sealing strip 1, the latter lays down after being fixed on the ridge batten 40 without any external influence lightly on the roof covering panels 60, with which the molding and gluing to the roof covering panels 60 takes place without pretensioning. After the protective film covering the adhesive beads 150 has been pulled off, the edge strips 90 which come to rest on the roof covering panels 60 and which are provided with the stretchable and in one embodiment also tiltable stabilizing insert S are now adapted to the wave shape of the roof covering panels 60. The adhesive beads 150 used to attach the stabilizing inserts S to the edge strips 90 are, as already mentioned, designed as a self-adhesive layer and now also serve to fix the edge strips 90 to the roof covering panels 60.

Continuous ventilation of the roof interior 20 while at the same time achieving watertightness is made possible by the gap remaining between the cover cap 70 and the edge strips 90 of the ridge sealing strip 1 in the region of the trough of the roof covering plates 60 (see arrow x in FIG. 15).

The exemplary embodiment shown in FIGS. 26 to 29 has longitudinal fold lines 210 on both sides of the longitudinal central axis of the ridge sealing strip 1. These are each arranged in the area of the corrugated edge strip 90 at a distance of approximately 20 mm from the outer edge of the connecting strip 80 and are achieved in the form of expressions of the wave troughs 220 up to the height of the wave crests 230. As can be seen in particular in FIG. 29, the edge strips 90 are thereby automatically bent in the direction of the roof covering plates 60. The longitudinal buckling lines 210 form predetermined buckling areas, which also offer the advantage that counteracting a tendency to return of the edge strips 90 after they have been glued to the roof covering panels 60 is counteracted is what can be done especially with dirty roofing panels 60.
