Definitions
- the invention relates to a sealing mat according to claim 1 and to a method for producing such a sealing mat.
- a sealing mat is known from the earlier patent application P 196 04 256.9.
- a perforated rubber or rubber band is provided for the air-permeable sealing of ridge and ridge stones on building roofs against drizzle and flying snow.
- the high density and thus the high specific weight of a rubber tape are the best prerequisites for the fact that such a tape material can be processed on the roof even in strong winds without running the risk of the sealing mat being carried away by the wind.
- the difficulty with the use of rubber tape is that a rubber bench cannot be permanently pleated or pleated due to its elastic properties due to profile rollers, but always tries to regain its smooth, flat shape.
- the edge areas and the central region of the flat, smooth rubber band are first coated with a thin metal strip, for example aluminum foil, which can be permanently deformed with little effort. Then only the metal strips with the areas of the rubber tape adhering to them are pleated by means of profile rollers. The metal strips are of such a thickness that the elastic restoring forces of the pleated rubber band areas are not sufficient to demold the pleated metal strips, ie to pull them smooth again.
- a smooth drawstring is glued to the pleated metal strips in the center area to ensure the dimensional stability of the pleated center area and thus its constant length under all conditions during assembly.
- FIG. 1 A perspective view of a length section of the known sealing mat is shown in FIG. 1, whereas FIG. 2 shows a section through an edge region of the known sealing mat according to FIG. 1 along the section line II-II.
- the known sealing mat 10 is placed with its pleated central area 3 (Fig. 1) on the ridge slat of a pitched roof and molded with its two pleated edge areas 2 against the surfaces of the adjacent roof covering panels on both halves of the pitched roof and glued to these surfaces with the help of adhesive tapes 6 .
- the air flowing out on the windward side of the pitched roof can flow in a transverse channel below the ridge block and above the sealing mat 10 and can escape again on the lee side of the pitched roof.
- the air flow in the transverse duct sucks air from the roof space through the air-permeable sealing mat 10 and takes this sucked-in air with it onto the lee side of the sloping roof, thereby ensuring effective roof ventilation.
- the known sealing mat 10 comprises, as an essential component, an elastic, water-repellent and air-permeable roller tape 1 made of calendered rubber sheet or of a fabric tape soaked or coated with rubber.
- Ethylene propylene tar rubber (APTK) with a high specific density is preferably used as the rubber material, although butyl rubber can also be used.
- the roller belt 1 has a thickness in the range between 0.2 mm and 2.0 mm and is needle-perforated over its entire surface or provided with punched holes (for example with a hole diameter in the range between 2 mm and 5 mm) in order to ensure good air permeability guarantee.
- the width of the roller belt 1 is, for example, 30 cm.
- the roller belt 1 is provided on the top of its two edge areas 2 and its center area 3 with narrow metal strips 2a and 3a, which preferably consist of relatively thick aluminum foil (thickness in the range of 0.1 mm).
- narrow metal strips 2a and 3a which preferably consist of relatively thick aluminum foil (thickness in the range of 0.1 mm).
- the width of the metal strip 2a is, for example, 5 cm and the width of the metal strip 3a is, for example, 4 cm.
- the metal strips 2a, 3a are preferably glued to the roller belt 1 by thermal lamination.
- the roller tape 1 as shown in FIG. 2, is provided on the underside of its two edge areas 2 with peel-off adhesive tapes 6, preferably made of butyl or bitumen adhesive.
- the peel-off adhesive tapes 6 are covered with a protective film, not shown, which is peeled off before the edge regions 2 are glued to the adjacent roof covering panels.
- the peel-off adhesive tapes 6 provided with the protective film are rolled onto the calendered roll tape 1 in its flat, smooth state before or after laminating on the metal strips 2a, 3a.
- the edge regions 2 (with the metal strips 2a) and the central region 3 (with the metal strip 3a) of the roller belt 1 are pleated by profile rollers, ie folded in the manner of a bellows (accordion-shaped) .
- the edge regions 2 and the central region 3 must not be demolded again due to the high elastic restoring forces of the rubber material of the roller belt 1.
- the thickness of the metal strips 2a, 3a must be chosen sufficiently large so that their deformation work is greater than the elastic energy stored in the rubber material during the deformation.
- a flat tension strip 5 made of, for example, self-adhesive plastic film is glued onto the pleated metal strips 3a.
- the pleated edge areas 2 can be effortlessly attached to the upper surface of the sealing mat 1 using the easily deformable metal strips 2a. Shape the surface profile of the roofing slabs, whereby due to the folding or pleating a sufficiently large material length is available to be able to adapt and glue the edge areas 2 to deeper grooves of the arched roofing slabs.
- the shaping of the edge regions 2 is retained after the molding on the roof covering panels 12, since the relatively thick metal strips 2a, 3a have a high shape stability which cannot be eliminated by the elastic restoring forces of the rubber material.
- the rubber material is additionally held in its end position by the adhesive forces of the puller tapes 6.
- the object of the invention in contrast, is to improve the bond between the rubber sheet and the metal strip at the edges in a sealing mat of the type mentioned.
- the invention is based on the idea of pressing the butyl material of each peel-off adhesive tape through perforation of the rubber foil of the roller tape during the thermal lamination of the associated metal foil.
- the underside of the metal foil is glued to the butyl material of the peel-off adhesive tape in a punctiform manner, in addition to the thermal lamination between the metal foil and the rubber foil.
- the punctiform additional gluing between the metal foils on the edge of the sealing mat and the peel-off adhesive tapes guarantees an absolutely safe and reliable connection of the metal foils even under unfavorable conditions, e.g. intensive solar radiation, in long-term operation of the sealing mat according to the invention.
- Fig. 3 shows a cross section through an edge region of a
- the rubber sheet of the roll material is provided at its edge regions 2 (FIGS. 1 and 2) with a plurality of perforation holes 1 a, which, at a mutual distance, extend on an imaginary line parallel to the outer edge of the rubber sheet.
- the perforation holes 1 a are preferably at a distance from the outer edge of the rubber sheet such that the perforation holes 1 a of each edge area come to lie centrally under the longitudinal axis of the metal sheet 2 a, which is laminated onto this edge area of the rubber sheet.
- the diameter of the perforation holes 1 a is in the range between 1.0 mm and 5 mm; their mutual distance is 1 cm to 2.5 cm.
- the butyl adhesive tape 6 is glued onto the underside of the metal foil with its free surface.
- the underside of the adhesive tape 6 is covered with a peel strip 6a. Due to the pressure of the pair of calender rolls, through which the sandwich structure of metal foil 2a, rubber foil 1 and butyl adhesive tape 6 is pulled during thermal lamination, butyl material of the adhesive tape 6 is pressed through the perforation holes la and reaches the underside of the metal foil 2a.
- a plug 6b made of butyl material forms in each perforation hole 1 a, the upper side of which is reliably bonded to the lower side of the metal foil 2a.
- each plug 6b made of butyl material forms a kind of anchoring between the adhesive tape 6 and the metal foil 2a.
- butyl plugs 6a is not limited to pleated sealing mats but can equally well be used on sealing mats with smooth edge areas.
