Definitions

  • the invention relates to a cover for covering and venting a ridge or ridge area of a roof according to the preamble of patent claim 1.
  • Ridge covers and ridge vents serve to seal the gaps left between the ridge batten and the roofing and at the same time to ensure ventilation of the roof truss. These columns run on both sides of the ridge lath in the longitudinal direction of the roof ridge. The ridge covers and ridge vents prevent the ingress of rainwater, snow, vermin or debris into the roof interior. At the same time the roof interior is vented to protect the roof against rotten damage.
  • a weather strip for a ridge or ridge cover with an air-permeable center strip and with adjacent side strips is already known (EP 0 341 343 B1).
  • the median strip consists of an air-permeable, water-repellent and snowproof fleece, while the side strips are made of soft polyisobutylene.
  • a similar ridge-sealing strip having a central region and two adjoining side regions is known from WO 99/09272.
  • the middle area here consists of a material that, although permeable to air or vapor, has rain and snowproof properties.
  • the side areas are moisture impermeable.
  • a ridge or burr ventilation element with a middle part, which can be fastened on a ridge or burr bar, and with side parts adjoining the middle part on both sides, which can be placed with their outer edge regions on roofing, is also known from EP 1 013 845 A1.
  • the outer edge regions consist of an air-permeable fabric and subsequent metal foil strip.
  • a ridge covering is known whose middle zone consists of a fleece which ensures the passage of air (EP 0 610 324 B1).
  • the middle zone is adjoined laterally by two needled edge areas.
  • the ridge seal is impregnated with acrylic resin.
  • air passageways are provided in the width direction.
  • the ventilation takes place essentially via a fleece.
  • the advantage of these seals is that they provide very good protection against flying snow.
  • the disadvantage is that the nonwovens form the ventilation levels directly.
  • the ventilation cross section is reduced to only 20 to 30% of the actual cross section.
  • it can come to moistening and water after prolonged exposure to water.
  • dust, insects or leaves can accumulate on the relatively flat ventilation fleece, which can at least temporarily lead to a significant reduction in ventilation.
  • ridge and burr ventilation elements are also known in whose middle and / or side strips air passage openings are provided (EP 0 974 712 A2, EP 0 117 391 B1). Upstanding edges may be provided around the air passage openings to prevent the entry of rainwater, which may possibly enter the uncovered joints between the overlapping ends of the cover caps (see EP 0 117 391 B1).
  • the advantage of the ventilation elements with air passage openings is that they have a good ventilation effect. Normally, water can not penetrate into the roof structure because the ventilation elements are covered by the ridge stones. In extreme weather conditions, when rainwater or snow are driven up by the wind, however, there is no safe tightness.
  • a ridge-sealing strip which has an average area enabling dehumidification of the underlying firewall, to which lateral water-repellent side areas each adjoin (WO 99/09272 A1).
  • the central region is infinitely variable in width at least in the adjoining region on each side region.
  • the well-known ridge sealing strip however, has no ventilation openings.
  • vents are provided in another known ridge sealing strip (GB 2 155 516 A1), but these vents are not separately protected.
  • a ridge pan which covers a ventilation opening (DE 199 54 417 A1).
  • the ventilation opening has a cover of air-permeable fine-pored material.
  • a cover strip for a ridge or ridge which has to be fastened on a ridge or burr staff center region and adjoining, an air passage enabling side strips (DE 93 19 360 U).
  • the base body of the cover strip made of foam rubber, foam plastic or polymer Kunststoffwirrfasern having air passage openings.
  • the invention is based on the object with a device according to the preamble of claim 1 to prevent the ingress of rain or flying snow through the ventilation openings at each position of the side strips with respect to the cover strip.
  • the invention thus relates to a device for covering and venting a ridge or ridge area of a roof.
  • This device has a center strip and two side strips, wherein the alslegbare on a ridge batten center strip is covered by an additional masking tape.
  • This additional masking tape is connected only to the central strip, so that the stretchable side strips folded down and can be molded to the top of roof tiles.
  • On both sides of the ridge batten are ventilation openings, which are shielded by the cover strip at a distance. So that no rain or snowfall reaches the ridge through the ventilation openings, an air-permeable shielding fleece is attached to the longitudinal edges of the cover strip and below the ventilation openings on the side strips.
  • the ridge element As long as the ridge element is rolled up, the Ablevlies with superposed folds between the cover strip and the side strips is arranged. After unrolling on the ridge batten and the unwinding of the side strips, the shielding fleece unfolds like an accordion.
  • the advantage achieved by the invention is thus that the ventilation holes are completely covered from above with a waterproof cover band and secured from the sides indirectly with a very air-permeable nonwoven. This ensures watertightness and good ventilation of the roof truss.
  • a device 1 for covering and venting a roof ridge is shown in a plan view, which consists essentially of the following parts: a cover strip 2, two well air-permeable bands 3, 4 and a roof connection tape 5.
  • the roof connection tape 5 is made in one piece and in its middle Area connected to the cover strip 2.
  • the cover tape 2 is preferably a thin plastic film with a certain rigidity. However, a thin metal foil or a reinforced nonwoven may also be used.
  • the two bands 3, 4 are preferably made of a fleece and are connected at one end to the roof connection tape 5 and at the other end to the cover strip 2. Instead of a fleece, however, woven or knitted fabrics can also be used.
  • Fig. 2 shows the same device 1 as Fig. 1, but in a view from below. It can be seen here the roof connection tape 5, which is provided in the middle with two parallel rows of ventilation openings 6 to 11, which are formed as slots. At the edges of the roof connecting band 5, an adhesive strip 12, 13 is provided, which consists of the actual adhesive strip - such as a butyl bead - and a peelable film.
  • FIGs 1 and 2 show only a section of a longer Firstrolle.
  • a complete Firstrolle 15 is shown, which is rolled up on site on a ridge lath.
  • the cover strip 2 is connected in its central region directly to the roof connection tape 5, z. B. glued or welded. Its edge areas, however, are connected to the webs 3, 4.
  • FIG. 4 shows the device 1 according to FIG. 1 with side strips 23, 24 of the roof connecting band 5 folded downwards.
  • the unfolding takes place in that the right and the left region of the roof connecting band 5 are moved toward one another in the direction of the arrows 20, 21.
  • the right and left areas of the roof connecting band 5 thus form the side strips 23, 24.
  • By unfolding the side strips 23, 24 remove the attachment points of the bands 3, 4, which is why the bands 3, 4 have a concertina-like folding.
  • a creped aluminum composite material is used, which contains an aluminum expanded metal mesh, said expanded metal mesh with a rainproof cover material, for. B. a fleece, is provided. Instead of a fleece but can also rainproof plastic material, eg. As polyisobutylene, are used.
  • the device 1 is shown in a built-in roof ridge state.
  • the median strip 22 of the roof connecting band 5 rests on a ridge batten 30, while the side strips 23, 24 of the roof connecting band 5 rest on roof tiles 31, 32, which in turn are hooked into battens 33, 34.
  • the roof battens 33, 34 are mounted on rafters 35, 36. With the rafters 35, 36, a carrier 37 for the ridge batten 30 is connected.
  • a ridge stone 38 covers the cover strip 2 and the roof connection tape 5.
  • About the ridge stone 38 is an overlap 39 with a bracket 40th
  • the ventilation openings 8, 11 are completely covered from above by the cover strip 2 and secured from the side by the air-permeable belts 3, 4.
  • the cover strip 2 which may be a plastic or metal foil, is mounted over the ventilation openings 8, 11 and forms a rigid roof, which adapts to the underside of the ridge stone 38, a protection against water in heavy rain and wind from above can penetrate through the covering 39 of the ridge stone 38. It thus forms a cross-sectionally roof-shaped shielding for the underlying ventilation openings 8, 11. In this way, the capping tape 2 in the covering area between the ridge stones penetrated water is reliably derived.
  • the cover strip 2 also serves as a nail band, with which the Firstrolle is attached to the ridge batten 30.
  • the bands 3, 4 are accordion-like between the cover 2 and the roof connection tape 5, the ventilation openings 6 to 11, arranged and welded or glued to the cover strip 2 and the roof connection tape 5.
  • the still flat rolled up material composite is mounted centrally through the cover strip 2 on the ridge batten 30.
  • the connection tape 5 pressed from creped aluminum composite material down and formed on the roof tiles 31, 32 and sealed by an adhesive strip 12, 13.
  • the air-permeable bands 3, 4 can be pulled down by folding and ensure at a certain distance from the ventilation openings 8, 11 an excellent protection against driving water and flying snow.
  • the ventilation openings 8, 11 are not covered directly by the air-permeable belts 3, 4, they retain their entire cross section of about 250 cm 2 / m ridge.
  • the device 1 has a ventilation effective area of 1 500 cm 2 per meter Firstrolle. Despite reduction of the air flow rate through the air-permeable belts 3, 4 to 20 to 30%, these belts 3, 4 still have an air flow rate which corresponds to a cross-section of more than 300 cm 2 , which ensures that even more air passes through the belts 3, 4 as through the ventilation openings 8, 11 goes.
  • the invention is not limited to the embodiment shown in FIGS. 1 to 5.
  • the cover strip 2 then lies directly on the ridge batten 30.
  • the side strips 23, 24 are still foldable, which is made possible by the material properties of the side strips easily.
  • the connection between side strips 23, 24 and cover strip 2 can be done by gluing or other suitable measures.
  • the air-permeable, but water-impermeable belts 3, 4 are formed as bellows. It is enough if they are stretchy.
  • Fig. 6 such a variant is shown. It can be seen here that the center strip 22 has been completely dispensed with and the side strips 23, 24 are fastened directly to the cover strip 2. The attachment can be done by gluing, such as with the help of fabric ribbons. It should only be ensured that the side strips 23, 24 are pivotable relative to the cover strip.
  • the bands 3, 4 extend parallel to the side strips 23, 24, d. H. unlike in FIG. 4, they do not form a bellows.
  • Fig. 7 shows a further variant of the invention, in which the two bands 3, 4 Parts of a uniform fleece are.
  • This web has a non-crimping center portion 44 disposed between the medial strip 22 and the masking tape. At this median strip close the two bands 3, 4 at.
