DE4343000C2 - Cover strips for a ridge or ridge - Google Patents

Description

The invention relates to a cover strip for a Ridge or ridge according to the preamble of claim 1.

Such a cover strip is from the EP 0 341 343 B1 has become known. It points out Central area and its two side stripes permeable, water-repellent and snow-proof res fleece, while its end strips each made of white best stretchy polyisobutylene film strips in which an expanded metal grid is embedded, in the longitudinal direction an extensibility of 50% to 150% and an extensibility of ≦ in the transverse direction 20% and a resilience of ≦ 5%. This cover strip is characterized by a flat and light from a so-called "burr roll" wrap-around design, but with the disadvantage afflicted that on the one hand the fleece is relatively quick Dust accumulates, which affects the roof ventilation is pregnant and that on the other hand the expanded metal in the end strips acts as a rigid corset, which just the one you want parallel to the ridge or ridge slat tenseness stands in the way. This is particularly true that the openings of the expanded metal grid from Polyisobutylene plastic are added and their rough either did not work by hand or only in vague ways Have it moved as necessary. This leads to angren zenden roof covering panels with pronounced Brim to shorten the end strips at the same time warping the stretchy and dated Fleece not impaired in its elasticity area. This can create tension between the Side stripes and end stripes as well as by the additional Chen temperature fluctuations too uneven the end strips on the roof roof plate and thus to leaks and to Be impairments or flow short-circuits of the loading lead ventilation.

In the non-generic DE 42 04 374 A1, two embodiments of roof ridge connecting tiles are disclosed which have a flat support surface on their head side facing the ridge, to which, according to the exemplary embodiments in FIGS. 5 to 7, an endless tape with two adhesive strips attached to the underside of its end regions is glued can be. This endless belt, which is also sometimes referred to as a sealing tape, should be flexible. A material or elasticity of this article is not disclosed. Since the problem of adapting a cover strip to a ridge connecting tile with a longitudinal and transverse fold does not occur here and the material of the endless belt remains open, it cannot provide any suggestion in the direction of the subject of the invention, especially since the terms “flexible” and “stretchable” are fundamentally related to one another have nothing to do.

DE 39 36 670 A1 is used as a sealing strip due to its large volume not rollable, in essential U-shaped foam body disclosed, the perpendicular or oblique to the surface in its Edge areas running at an angle of approx. 45 ° Has incisions. According to the disclosure content of this This foam strip can be pre-released on the one hand, sufficient porosity for loading and Have ventilation and on the other hand also from air-impermeable, polymeric material. To this However, air permeability of the material occurs in the not in the present case because the parallel running incisions on the edge areas of the Foam strip under the pressure load of the sitting ridge stone to a fanning this Incisions with corresponding air flow channels lead, the flow resistance is certainly less than is that of the open-cell foam strip. That I the air always and therefore the path of the least Searches for flow resistance, this leads through the Flow channels of the fanned incisions and not through the open-cell foam strip. From the Disclosure content in column 1, lines 58 to column 2, Line 8, the person skilled in the art takes from this document that through the cut incisions for the otherwise stretched areas of cohesion Material is canceled and therefore without noteworthy strain in the peripheral area diverge like a fan. In this publication is only a compressive stress on the foam strip disclosed. However, compressive stress results in everyone Case to a reduction of possibly in the elastomer Material existing air passage openings.

Another, non-generic cover strip according to DE-OS 26 49 790 is formed in two layers, an upper strip made of harder material and a lower strip made of softer material, both strips are connected to each other only in the region of the longitudinally extending strip center. In the lower strip at least in one strip half ventilation openings are provided and the width of the upper strip is arranged to cover the ventilation openings. This cover strip allows an air flow around the upper strip only in the area of the scaled ridge stones near their support, however, the upper strip seals the air flow channel in the downward falling area of a ridge stone, as shown in FIGS . 1 and 4 the reference number 11 emerges. As a result, the ventilation in these areas is limited to a con vective effect, whereas the suction effect in this area ceases to exist with a flow around the cover element between an upper side and the lower side of the ridge stone. The upper strip should consist of hard PVC and the lower strip of soft PVC. But also soft PVC has by no means such a stretch in the longitudinal direction of the ridge that the lower strip fits snugly and airtight on the adjacent roofing slabs, which is not the case in particular if these are strongly curved. Then flow short-circuits affecting ventilation are unavoidable.

Based on this state of the art, the Invention the task of a cover strip to create the genus mentioned at the beginning inexpensive manufacture effective ventilation as well excellent stretch in both longitudinal and also guaranteed in the transverse direction and yet that Penetration of flying snow and driving rain widely prevented.

This task is in conjunction with the beginning mentioned generic term according to the invention through the characteristic features of claim 1 solved.

Through training of the base body from a foam rubber, from a Foam plastic or polymeric plastic tangle fibers, a basic body is created that is expandable in toto, the one with the self-adhesive layer on the bottom its end strips on the roofing slabs of the glued a roof side, then over the ridge batten - with or without attachment to it - cocked and afterwards on the surface of the roof covering plate on the other side of the roof with its other end strips can be glued. If there is Base body made of an open-cell, highly entropy and therefore easily expandable Polyester, polyether or filter foam, so the Air vents through the open cells of one such foam plastic and formed by a corresponding preload increased accordingly or reduced with a lower preload.

An attachment of the base body is also on the ridge slat by means of nailing, screwing or Gluing is always advantageous, but absolutely necessary Lich is appropriate if the inventions are designed accordingly Basic body according to the invention from a foam art not fabric. However, the basic body consists of egg closed cell foam plastic, for example wise from a polyethylene or a PVC foam fabric or a cellular or natural rubber or a other closed-cell foam plastic, such as Chloroprene rubber, so in the side stripes Air openings punched. these can then both on the top and / or on the bottom side of the base body covered by a non-woven fabric will.

After an advantageous further training of the Erfin manure is the main body in its central area with provided with a flexible plastic strip, the width of which at least as large as the width of the edition surface of the ridge or ridge batten. This ent is an extremely effective ventilation by means of a Suction pump jet effect when caused by wind The ridges or ridges flow vertically and thus this outside air is largely unhindered below the ridge stone of which a Aufsetzkan te from the windward to the leeward side to its other landing edge can flow. In addition, the Mit plastic strip reinforcing the area base body on the ridge or ridge  by means of screwing, nailing or gluing relieved.

To ensure an always extremely effective loading The width of the central area becomes ventilation on the one hand at least as wide as the bearing surface of the ridge or rake, but on the other hand not so wide, that airflow between the bottom of the Ridge stone and the top of this middle area is prevented. Because such a flow the atmospheric outside air ensures during the passage above the cover strip for a vacuum, whereby air from the attic below is sucked in. The width of the masking tape is advantageously designed so that an effective flow can take place in the manner described above and nevertheless the hard shoulder against incoming flight snow or other precipitation with release the air passage openings are covered. The in Cantilevered towards its two side strips Median strip is designed as a "canopy". At the Foam rubber and foam plastics will come to mind rain anyway in the sponge-like Side stripes caught and from the one with a troc keneffekt associated flow in vapor according to the state again in the outside atmosphere leads.

The end strips are advantageous on their top and / or on its underside with a polymer, air and waterproof coating or over their entire layer thickness with a polymer, soaked in water-repellent material. Thereby be carries the elasticity of the side and end strips in Longitudinal direction of the ridge or ridge at least 20% and in the transverse direction at least 5%. This stretch ability is however with foam rubber or foam plastic significantly larger.

The flexible plastic strip in the middle area is according to an advantageous development of the invention either a strip of polyethylene, ABS or another entropy-elastic film posed or is of a complete soak this central area with a polymeric measure formed material. This soaking material consists in Center area and in the end strips advantageous one at the temperatures to be taken into account weather-resistant bitumen or from tough plasti bitumen mixtures or latex or butyl rubber. The tough plastic materia lien or their mixtures before they harden into one tough plastic condition, especially on the final strip with a quartz sand up to a grain size of 5 mm can be sanded. The middle area and / or the end strips are advantageous on at least theirs Top with a water-soluble in the application stage color, but after setting water-insoluble color, e.g. B. a latex emulsion paint. Through the Choosing the same coloring will match the final stripes also optically favorable the adjacent roof cover plates.

The self-adhesive layer is at the bottom of the end stripes in the form of a continuous straight, wavy moderately or meandering line or in Punktarti applied to zones and removed with a hand removable protective strips. By means of this Kle the end strips are coated more or less strong preload of the expandable, strong tropical elastic side stripes on the top of the Adjoining roofing tiles and there sealed in this area so that the atmo spherical outside air only above the end strips and thus the cover strip between this and the Underside of the sitting ridge stone from the windward can flow to the leeward side of the ridge.

There are several in the formation of the basic body Embodiments possible.

According to a first embodiment, the Base body made of an open-cell, expandable Polyester, polyether or filter foam, in which the air vents through the open cells of the foam plastic are formed.

According to a second embodiment, the Basic body made of a PE foam with offset tent len.

According to a third embodiment, the reason body of a closed-cell polyethylene or PVC foam or a cellular or natural rubber formed in which in the side stripes Air openings are punched. When once tion of the air passage openings, these are advantageous on the top and / or bottom of the basic body pers covered by a fleece to prevent penetration to largely prevent precipitation.

The size of the open cells of the foam plastic fes is in a range between 0.5 mm and 3 mm.

Referring to FIGS. 1 and 2, the cover tape 1 for a first 2 of a te on a ridge or Gratlat 3 to be fixed middle area 4 having thereon at closing, an air passage enabling Be tenstreifen 5 and with sealing, to the upper surface 7 a of the Adjacent roofing sheets 7 adaptable end strips 6 , which are provided on their underside 6 b with a self-adhesive layer 8 .

According to the invention, the base body 9 of the ex cover strip 1 comprising a air passage openings 10, closed-cell foam rubber 11 as shown in FIGS. 7 to 10 or of an open cell plastic foam 12 as shown in FIGS. 5 and 6, 12 and 13 as well as 14 and 15.

This base body 9 is provided in the embodiment according to FIGS. 5 and 6 in its central region 4 with a flexible plastic strip 14 , the width te B according to FIG. 6 on the one hand at least as large as the width A of the bearing surface 15 of the ridge or ridge batten 3 is shown in FIG. 1 and the other hand, in Einbauzu stand according to FIGS. 1 and 2, between its upper face 14 a and the bottom 17 a of the seated First stone 17 a a-allowing air flow around the passage section 18 can open. The ridge stone 17 with its support edges 17 b always sits on the brim 7 b (see left side of FIG. 2) which forms a "mountain" in cross section, whereas between the adjoining "valley" 7 c of a covering plate ( see right side of FIG. 2) and the glued-on top 16 of the cover strip 1 and the end edges 17 b of the ridge 17 openings 31 are kept free for air to pass through. This passage of air is indicated in FIG. 2 by the arrows 19 .

When the outside air flows in the direction of arrow 20 from the windward to the leeward side according to arrow 21 , this air penetrates into the intermediate space 22 according to arrows 19 , which comes from the underside 17 a of the ridge stone 17 and the top 16 of the cover strip 1 is formed. The air flows around the cover strip 1 , whereby air is entrained from the roof space 23 below by means of a jet pump effect through the air passage openings 10 in the side strips 5 according to the arrows 24 and reaches the leeward side according to the arrow 21 with the air flow 19 . During this air flow around the cover strip 1 , moisture, for. B. due to an entrained with the air flow precipitation in the form of rain or snow, which is removed by drying back into the outside atmosphere. In order to largely protect the cover strips 1 from such precipitation, the end strips 6 are provided on their top side 6 a and / or bottom side 6 b with a polymeric, air and water impermeable coating 25 or over their entire layer thickness 26 according to FIG. 17 with a polymeric, water-repellent material 27 soaked.

The extensibility of the side stripes 5 and end stripes fen 6 is at least 20% in the longitudinal direction according to arrow 28 of the ridge or ridge 2 of FIG. 1 and at least 5% in the transverse direction according to arrow 29 . With foam rubber 11 and foam plastics 12 , the extensibility is generally the same in both directions.

The flexible plastic strip 14 in the central area 4 either consists of a cover strip made of polyethylene, ABS or another entropy-elastic film or is formed from a polymeric material 37 with which this central area is completely saturated (see FIGS. 14 and 15).

The impregnating material 37 , 27 in the central area 4 and in the end strips 6 consists of a bitumen at the temperatures to be taken into account or of tough plastic bitumen mixtures or of latex or butyl rubber. These tough plastic materials or their mixtures can be sanded with quartz sand up to a grain size of 5 mm before they harden into a tough plastic state. The plastic strip 14 and / or the end strips 6 are at least on their Obersei 14 a, 6 a with a water-soluble in the order stage Chen, but after setting water-insoluble color, eg. B. a latex emulsion paint.

The self-adhesive layer 8 is applied in all drawings in the form of a continuous straight line 8 a or zone 29 (see FIGS. 5 and 6). It is also possible, however, 8 of which deviate apply these self-adhesive layer accordingly wavy or meandering or in point-like zones and provided with a manually removable protective strip 30th

In FIG. 3, parts that correspond to FIGS . 1 and 2 are designated with the same reference numbers. This figure shows particularly clearly the grandeur in the form of the "mountains" of the brim 7 b and the gutters between them as "valleys" 7 c of the individual roofing panels 7 , which makes the representation of the ridge stone 17 according to FIG. 2 understandable. Because in the left half of the picture the ridge stone 17 sits with its edge 17 b on a "mountain" of the brim 7 b, whereas in the right half of the picture the section through a "valley" 7 c leads to a gutter of the roofing panels 7 . This results in the air through openings 31 required for the flowing air according to the arrows 19 according to the right half of FIG. 2.

In Fig. 4, the cover strip 1 is unrolled from a gratrol 32 such that the central region 4 with the plastic strip 14 is rolled on a ridge or ridge batten 3 and, after the cover strips 30 have been pulled off according to FIG. 6, the end strips 6 with their underside 6 a on the top 7 a of the adjacent roof roofing plates 7 are glued.

Due to the relatively large extensibility of the highly entropy-elastic side stripes 5 with the air passage openings 10 , which are characterized in the present case by the individual points and are formed by the open cells 35 of the foam, and by the same corresponding flexibility and stretchability of the end strips 6 , the inventive Cover strips 1 with the correspondingly large elasticity both in the longitudinal direction of the ridge or ridge batten 3 according to the arrow 28 and also transversely to the arrow 29 laid and fixed. By a greater or lesser bias of the base body 9 in the side strips 5 , the size of the air passage openings 10 can be regulated, which are formed here by the open cells. This also allows a corresponding regulation of ventilation. The end strips 6 in the present case according to FIGS . 5 and 6 are provided with a water-impermeable coating 25 which has approximately the same expandability and flexibility of the base body 9 of the cover strip 1 .

The subsequently described FIG. 5 to 19 un differ from each other mainly by ih ren respectively different base body 9, an arrangement, the coating 25 and / or the Durchträn kung 27, 37, the structure of the plastic strip 14 and the design of the air passage opening 10 , which results from the following:

In FIGS. 5 and 6, the base body 9 made of a plastic foam 12 having open cells 35 as the air passage openings, a sigen in the central region 4 accommodated, flexible plastic strip 14 and of a arranged on the end strip 6 wasserundurchläs coating 25. This cover strip 1 can be seen in its installation position from FIGS. 1 to 4.

In Figs. 7 and 8 are designated by the Fig. 5 and 6 correspond tuning parts with the same reference numerals. In contrast to the above-described figures, the base body 9 now consists of a closed-cell foam rubber or a closed-cell foam plastic in which openings 10 are punched into the side strips 5 . The middle region 4 is here also cover strip of a flexible plastic cover 14, which can be used with the cover strip 1 nailed on a ridge or roof edge lath 3 or otherwise secured. The plastic strip 14 can also be attached to the central region 4 by gluing and this on its underside 4 a also by means of gluing on a ridge or ridge batten 3 .

The side stripes 6 are colored on their top with an adjoining the roofing tiles 7 th, waterproof latex emulsion paint 33 .

FIGS. 9 and 10 differ from Figs. 7 and 8 characterized in that the inserted into the base body 9 punched air passage openings servlies by an air-permeable Fa 10 at the top 5 a of the side strips 5 cover 34 to largely gen a Eindrin of To prevent precipitation in the form of rain or snow towards the roof interior 23 . The entire base body 9 is completely colored up to the end strips 6 with a color corresponding to the surface color of the adjacent roofing panels. The transition from the side strips 5 to the end strips 6 is therefore designed continuously and without an optically visible transition.

In Fig. 11 the cover strip 1 of Figure 9 and 10 in its installed position shown in FIG. 1. FIG. As is apparent from, although in this embodiment the width B of the plastic strip 14 is wider than the width A of the supporting surface 15 of the ridge or roof edge lath 3 tet decor with dark, however, this cover tape 1 can be between its upper side 16 and the upper surface 14 of the plastic strip 14 by Release of passage openings 18 according to FIG. 2, an air passage from the leeward side (arrow 20 ) to the windward side (arrow 21 ). So that by means of the highly absorbent jet pump effect, a suction of the air from the attic 23 below it through the openings 10 and the nonwoven fabric 34 is ge security.

In Figs. 12 and 13, the base body 9 of an open cell foam plastic 12, the open cells 35 provide an air passage through the side strips 5. The end strips 6 are provided with a water-impermeable coating 25 both on their upper side 6 a and on their lower side 6 b. The number of cells 35 in the form of the dots indicates the ridge of the open porosity both in the top view of FIG. 12 and in the cross-sectional view of FIG. 13. These are few, but relatively coarse-pored cells 35 , in contrast to the fine-pored cells 36 as openings in FIGS. 5 and 6.

In Figs. 14 and 15 of the basic body consists of an open cell 9 as derum strongly entropieelasti rule polyester, polyether or foam filter, in wel chem the air passage openings are formed through the open cells 35 in the side strips 5. The end strips 6 are provided on their underside 6 b with a water-impermeable coating 25 . The flexible plastic strip 14 in the central area 4 consists of egg nem polymeric material 37 with which the central area 4 is completely saturated. This has been graphically differentiated by the different hatching in contrast to the adjoining open cells 35 of the side stripes 5 . It is understood that if the water-impermeable coating 25 on the underside 6 b of the end strips 6 ceases to exist, these may also be provided with egg nem water-repellent material 27 according to FIGS. 16 and 17. In these figures, the base body 9 consists of a closed-cell polyethylene or a PVC foam or of a cellular or natural rubber, in which strips 5 the air passage openings 10 are punched in the sides, which are covered on the underside 5 b by a non-woven fabric 34 . In addition, the end strip 6 is impregnated over its entire thickness 26 completely with a polymeric, water-repellent material 27 which roam the denser dashed Strichschraffur in this end is indicated. 6

In Figs. 18 and 19 of the base body 9 is formed of a foam plastic 12 with staggered cells 36, which is indicated by the dot and Strichschraffur. As a result, the side strips 5 are air-permeable, but due to the offset cells 36 with a greater air passage resistance connected ver. The end strips 6 are provided both on their upper side 6 a and on their lower side 6 b with a water-permeable coating 25 . Be this coating 25 can also get away and by a water-insoluble color after application and setting, z. B. a latex emulsion paint, who replaced the.

In summary, it can be said that the essence of the invention is based on the one hand in the design of the basic body 9 in the form of a highly entropy-elastic foam material or foam rubber, in the sponge-like sides strip 5 falling precipitation settle and then by the air flow (arrows 19 ) according to Fig. 2 can be sucked off in vapor form by means of a jet pump effect and returned to the outside atmosphere. In this case, the base body 9 is hochentropieelastisch, can be colored as desired or shipping hen at the surface with a latex emulsion paint and the air passage bestreifen 8 by a more or less strong stretching at bias the side strips 5 between ridge batten 3 and adhesive strip 8 or Kle to tape 8 be regulated. In addition, such a cover strip 1 can be unwound very easily from a burr roller 32 and attached to a ridge or ridge lath 3 . Both the polymeric coating 25 and a corresponding latex di-dispersion paint 33 are advantageously designed UV-be constantly by appropriate admixtures against the sun, so that permanent ventilation on the one hand above the surface 16 of the masking strip 1 is ensured as well as permanent BEFE Stigung by means of the adhesive strip 8 on the top 7 b, 7 c of the adjacent roofing panels 7th
