The edge of the strip at the gutter (11) is thinner, with a thickness of 100 mu m to 1.0 mm and pref. 150-600 mu m, with at least one bending zone (4a,4b). The sealing strip is of metal or plastics materials.

Description

The invention relates to a sealing element for an eaves, which as a flat band and at least is so wide that it covers the gap between a roof and a gutter can.

With such sealing elements, the gap transition from the roof side to is usually bridged to the gutter. These eaves sealing elements have so far mostly been made of zinc sheet, but also made of plastic.

For example, EP 0203670 A2 discloses a sealing element that rests on an eaves roof batten is nailed. A eaves comb is positioned above the element. This is from the Roof tiles pressed down to keep out birds, vermin, etc. On the opposite side of the Elementes a plastic corrugated sheet is installed, which opens far into the gutter and also from there the roof seals on the eaves.

Another sealing element is proposed in DE 296 11 015 U1 as a eaves sealing membrane, which is molded in one piece from elastic material. The eaves strip is here preformed at a fixed angle and so dips into the gutter.

Another sealing element is shown in DE 197 08 130 A1, where the angled strip, which dips into the gutter, is lined with lead.

Usually, a zinc sheet is used as a sealing element on the roof, usually on one Side is folded. A rigid angle is formed in plastic elements. The element is attached as a strip to the rafters or the eaves plank and the angled one Part of the element is led into the gutter. This solution is not optimal, because at Different roof pitches arise assembly problems because of the rigidly specified Angular position. The angle can also change with temperature changes in this area change. On the other hand, according to the prior art, such rigidly predetermined angles Necessary, since it acts as a stop when positioning the sealing elements before their final fastening can serve.

To ensure that the moisture that accumulates on the roof is traditionally used Roofing membrane fastened to the rafters over the entire roof (below the roof tiles) and laid up to about 10 to 20 cm before the end of the roof. It is usually on the Eaves-side end fastened to the eaves sheet with adhesive strips or nailed there. there detachments and leaks can occur.

It is the object of the present invention to provide an eaves seal, which Overcomes the above disadvantages of the prior art. In particular, the eaves sealing element easy to lay and position and suitable for all roof pitches and good be sealing.

This object is achieved in that the eaves sealing element has at least one bending zone which extends in the longitudinal direction of the band and one flexible bending of the band permitted.

By providing bending zones, the element is very easy to lay and can be used by everyone possible installation situations can be optimally adapted. Such special bending zones are like this can be designed so that they prevent the occurrence of leaks, e.g. occur can, if rigid elements are bent to adapt to the installation situation have to.

In one embodiment, the element is at least in the region of its gutter protruding end so flexible that it can be done manually or by gravity can be bent into the gutter. According to the invention, therefore, a predetermined Angling the end projecting into the gutter is dispensed with, so that the eaves sealing element can be used universally, with all possible roof pitches. Because of its flexibility, it will either by gravity alone bend freely hanging end in the gutter or there may be such a bend in the Laying can be done by hand. It is also possible on the gutter side Attach the edge of the eaves sealing element to the underside of the caterpillar tracks. With their With help, this edge can then be glued into the gutter.

In one embodiment of the present invention, the flexibility required thereby created that the eaves sealing element at least in the area of its in the gutter protruding end is formed as a very thin band, in particular with a thickness of 100 µm to 1 mm, preferably 150 µm to 600 µm.

In a further embodiment, the eaves sealing element has at least in the area have at least one bending zone of its end protruding into the gutter. Such According to the invention, the bending zone will either be thinner than the surrounding material or through a corresponding shape, for example by a flat design, a bending ability produce. If, for example, at least one eaves sealing element according to the invention If the pleating has sections in the longitudinal direction, the bending zones can especially formed by flat-worked pleating sections. Such Processing into a flat section is particularly possible if the eaves sealing element is provided as a metal band. Here is the easiest Way of manufacturing in that the metal strip is initially completely pleated and the bending zones then create by flattening longitudinal pleating sections.

Furthermore, the eaves sealing element can also have additional flat-worked sections have in the region of its roof-side end, the arrangement of with the sealing element easier to connect components. For example, such flat section placed an eaves ventilation element or attached a sarking membrane become.

In principle, such bending zones can also be achieved by simply notching the pleating getting produced.

If the eaves sealing element according to the invention has a metal band, this can made of aluminum, copper or lead or another flexible and preferably plastic deformable metal material. There is a preferred embodiment in building the eaves sealing element from several layers, in particular from an inner metal layer to outer UV-resistant plastic layers. The metal layer ensures the plasticity when bending into the gutter, while the plastic layers make the sealing element weatherproof. The metal layer can, to make it more flexible, be provided with recesses, for example with punched holes, which are then through the Plastic layers are covered.

Within the scope of the present invention, it is also conceivable for the eaves sealing element to manufacture from a plastic material. Such production is carried out by spraying or Extrude, and here, too, the bending zones can basically be done by flat-worked pleating sections be formed. In general, all of the mold designs presented above can also realized by a eaves sealing element made of a plastic material become.

Furthermore, the bending zone according to the invention can also have at least one film hinge. Also it is possible in the area of the gutter-side section on the underside of the eaves sealing element Attach adhesive beads to adhere the element at this point fasten.

The sealing material preferably has a width of approximately 250 to 300 mm and can be rolled up, For example, be provided as a roll of about 5 to 10 m in length. It is also also possible to provide the element unrolled in lengths of 1 m.

As previously mentioned, the eaves sealing element according to the present Invention have a pleated band, preferably a metal band, in which the bending zones by means of flat sections, in particular flat, attached between pleating sections worked pleating sections are formed. Such bending zones can now be very different Take on tasks.

In one embodiment, the eaves sealing element has, for example, at least one Bending zone that is at such a distance from the gutter-side longitudinal edge of the band is arranged and has such a width that the longitudinal edge region over the at the roof edge the bending zone to be reached extends in an arc into the gutter. The bending zone can have a distance of 15 to 70 mm from the gutter-side longitudinal edge and have a width of 2 to 70 mm.

If you choose a very wide bending zone with a small distance from the gutter side Long edge, so you can ensure that the eaves sealing element over a Bending radius arched into the gutter. This prevents sharp-edged Bends occur that could affect the long-term strength of the element.

By varying the width and the distance of the bending zone from the gutter side The longitudinal edge of the element in the area shown above can be optimally adapted in each case Create sealing elements for all conceivable installation situations, and with very little Manufacturing effort. It just has to be the tool that the Pleating can be worked flat, made wider or narrower or offset in the width direction become.

In a further preferred exemplary embodiment, the eaves ventilation element has at least a bending zone that is at such a distance from the gutter side longitudinal edge of the band is arranged and has such a width that the remaining pleated Longitudinal edge area to be fixed behind a roof-side inner hook of the gutter can be. This allows the eaves sealing element according to the invention to be used in accordance with this Position the embodiment firmly on the gutter and ensure an optimal seal with a very simple mounting method on site. The fact that the invention Bending behind the gutter hook takes place, no water splashes into the space between The eaves sealing element and the contact edge penetrate.

According to a further preferred embodiment of the present invention, this Eaves ventilation element on at least one bending zone, which is at a distance from the gutter side Longitudinal edge of the tape is arranged so that the remaining pleated longitudinal edge area developed to form a water protection edge to the top of the tape at the back, in particular can be bent back to the top. The bending zone can be one Have a distance of 15 to 40 mm from the gutter-side longitudinal edge and a width of Have 2 to 30 mm.

So here is a bending zone on the other side of the sealing element for optimization used its function. By bending the longitudinal edge area upwards another water protection edge on the eaves sealing element, which prevents splash water from the gutter side, for example by wind over the eaves sealing element is driven upwards and penetrate into the roof substructure behind the sealing element can. If the longitudinal edge area to be angled up to the top of the eaves sealing element is bent back, a practically insurmountable threshold for penetrating water and on the other hand can thereby increase the element in it Area can be obtained, which also acts as a water retention device when over the Eaves sealing element is also pulled, for example, a sarking membrane. Depending on The width and distance of the bending zone may be necessary or adapted to the installation situation preferably be selected in the range listed above.

According to a further aspect of the present invention, the eaves sealing element is made from several interconnected longitudinal elements in the area of their side edges are attached to each other, with both side edges bent back in a U-shape in this area and are mutually engaged in the resulting recording. This can be used in particular achieve clawing of two successive longitudinal elements in the case of pleated elements, which ensures a good sealing and very firm connection. This connection is also easy to manufacture.

This connection is advantageously established if there are none in the region of the side edges Bending zones and in particular an undeformed pleating is provided, since this is Direction can then make an easier turn.

In order to strengthen the connection of the longitudinal elements, the engagement area can preferably the longitudinal elements for strengthening the connection be flat deformed.

The eaves area shown in Figure 1 has a rafter 17 on which the eaves plank 13 finally rests. Over the rafters 17 and the inner section of the eaves plank 13 runs the underlay 16, which is also held by the crossbar 15, among other things.

Furthermore, in the eaves area there is a gutter 11 over several gutter bars 10, only one of which is shown attached to the eaves plank.

To seal the roof gap, i.e. for water that collects on the roofing membrane, the eaves sealing element according to the invention is derived without leakage into the gutter 1 provided. The attachment and design of the eaves sealing element according to the invention can best be seen from an overview of FIGS. 1 and 2. First, however, the eaves sealing element 1 itself is to be explained in more detail with reference to FIGS are explained.

In this embodiment, the sealing element 1 is a metal strip, which in FIG the top view can be seen. It has a width (from left to right in FIG. 3) of approximately 250 up to 300 mm and a thickness of 150 µm to 600 µm.

The sealing element 1 has a flat end at its end shown on the right in FIG Area 2, which is followed by a pleated area 8. This is followed by a flat one Area 3, then a pleated strip 7, a flat strip 4a, a pleated strip 7a again flat strip 4b and finally a pleated strip 7b on the left. The kind of Pleating in the pleated strip is, in this embodiment, as can be seen in FIG. 6, wavy; but it can also be meandering or zigzag-shaped. A side view in the direction of arrow X in FIG. 3 is shown in FIG. 5, where again the different ones pleated and flat sections are clearly recognizable. The pleating of individual sections serves two different purposes in particular. On the one hand, this leads to water drainage simplified, while on the other hand a certain dimensional stability in the pleated areas is created, which prevents that shown in Figures 3 to 5 on the left, in the Gutter protruding end becomes too unstable and simply tilts down.

A simple manufacture for a metal sealing member according to the present invention will be explained with reference to Figures 4 and 5. Figure 4 shows one of the View X in Figure 3 corresponding view for a metal strip (element 1) that is continuous is pleated. The band shown in Figure 4 thus corresponds to that shown in Figure 3 without the flat areas 2, 3, 4a and 4b.

After such a continuously pleated metal band has been produced, it is made by Pressed flat at points 2, 3, 4a and 4b, so that zones 4a and 4b as Bending zones are created, while in areas 2 and 3 there is a flat material for attachment other components are created.

The eaves sealing element 1 is now on as shown in Figures 1 and 2 the eaves misplaced. For this purpose, the rear flat section 2 is finally on the roof side roof-side fastening extension of the gutter 10 or between these gutters on the Eaves board 13 placed. The underlay 16 is now over the flat section 1 pulled to the pleated section 8. Then the attachment takes place by gluing or Nailing instead.

The water can now directly from the roofing membrane 16 to the eaves sealing element flow and is discharged in a straight line through the pleated area 8. Left side from the pleated area 8 there is again a flattened section 3. This flattened section Section 3 is provided so that at this point an eaves ventilation element 20 can be put on, which has a comb 18, the roof tiles 9 is pushed down.

At this point it should be noted that flattening of area 3 is not absolutely necessary is because the eaves ventilation element can also be mounted directly on a pleating.

The section of the eaves sealing element according to the invention adjoining the flat area 3 on the left now alternately consists of pleated and pressed sections. The area 3 is followed first by a pleated section 7, then a flattened section Section 4a, then a pleated section 7a, a flattened section 4b and finally a pleated section 7b. Pleated in this sequence and flattened strips creates a flexible construction that is very simple in the desired one Arc shape can be bent into the gutter. While the remaining pleated Sections 7, 7a and 7b provide sufficient rigidity, the flattened serve Sections 4a and 4b as bending zones, which make it possible for the laying craftsman a suitable bend in the gutter for all possible roof pitches put. The eaves sealing element according to the invention can therefore be very universal and regardless of the roof pitch.

The bending can be done manually and plastically, but it is also possible, for example, that Choose the material thickness and the width of the bending zones in advance so that the Gravity forms a suitable arch shape when laying, so that the water from the Unterspannbahn 16 forth safely and without leakage into the gutter.

The width of the flattened section 4a between the pleated sections 7 and 7a can also be chosen so that the sealing element 1 on its underside in Area 4a over the roof-side inner hook 19 of the gutter 11, so that here at the same time a clear positioning of the element 1 towards the gutter 10 is made possible.

In general, it should also be noted that the metal strip is pretensioned due to its Flexibility is not available, this is only on the eaves plank and with the eaves ventilation element stipulated, in turn, for a suitable ventilation of the entire building physics system ensures that the underlying thermal insulation by condensing water can't get wet. The number of flat bending zones 4a, 4b can vary depending on the necessary ones Events are determined; for example, it is an adaptation to the size of the gutter conceivable.

If the sealing tape has multiple layers, e.g. three layers with a middle metal layer and two outer plastic layers is formed, the plastic layers are weatherproof and should have a thickness of approx. 0.5 to 0.8 mm. To the flexibility and plasticity too ensure, it is possible, for example, the central metal layer with openings to provide.

FIGS. 7 and 8 show a further embodiment of an eaves sealing element according to the invention. From its gutter-side edge KR, it consists of a short one pleated remaining area 27, an area 23 with flat deformed pleating, one again pleated area 28, a region of flat-shaped pleating 22 and a further pleated edge section 21 on the roof-side edge KD of the element.

The areas 23 and 22 each form the bending zones.

The processing and the assembly state of the element shown in Figures 7 and 8 are shown in Figures 9, 10 and 11. In Figure 9 it is indicated on the right side how the roof-side longitudinal edge section 21 is bent upward over the bending zone 22, so that the sealing strip shown in Figure 10 is formed. The strip 21 is up to the Surface of section 28 bent back. The element prepared in this way is then on the roof assembled and there as already described above via the eaves ventilation element 20 and one Nail 24 attached. The nail can be hammered in before folding and bending of the longitudinal edge section 21 is carried out.

In the gutter area, the eaves sealing element now projects over its bending zone 23 with the still pleated longitudinal edge area 27 into the gutter to drain water into it.

It extends over the inner hook 19, namely in the form of an arc in a bending radius, which, as already described above, is a very simple adaptation to all possible gutter designs allowed. In addition, there are no sharp bends in the curved area, that could lead to breaks, and thus extends the embodiment described here significantly the life of the element.

At the roof-side end, the longitudinal edge section 21 bent back onto the upper side forms a excellent working water protection edge for splash water, which is caused by wind reaches the middle part of the eaves sealing element and is driven upwards. This water is caught in the U-shaped curvature in the area of the bending zone 22 and the bent-over longitudinal edge section 21 and can therefore in no way further up penetrate into the roof substructure. The roofing membrane 16 runs from the roof to the top projecting section of the longitudinal edge region 21 and is fastened there.

The other figures have the same or functionally identical components as in Figures 9 to 11 reference numbers increased by 10 in each case. Only those components are discussed that are designed differently from the above-described embodiment.

The eaves sealing element shown in Figures 12 to 14 has a gutter side relatively narrow bending zone 33, which is also a slightly larger distance from the gutter side Edge. As a result, an essentially completely pleated roof gutter protrudes Longitudinal edge section 37 into the gutter, with the guidance of the water drain advantageously designed.

On the roof side, the eaves sealing element is designed and fastened in the same way as this was described with reference to Figure 11, except that the underlayment 16 now over the longitudinal edge section 31 and under the eaves ventilation element 20 pulled through and thus attached. The roofing membrane 16 thus receives through the Elevation at section 31 has a steeper course and can therefore be driven by wind Keep splash water away better. Even in the case where there is 16 May form cracks above the eaves sealing element is because of the bent back Section 31 also includes the previously discussed water barrier, the one Preventing the water from running upwards is prevented.

In the embodiment shown in FIGS. 15 to 17 there is a combination of the Versions as previously described. This embodiment has the gutter side a wide and close-to-edge bending zone 43, with the advantages as already with regard to the embodiment of Figures 9 to 11 have been shown while in the roof-side section the underlay 16 has been attached in the same way as with reference to FIG. 14 has been described.

Another advantageous embodiment of an eaves sealing element according to the invention is shown in Figures 18 and 19. Here again the sealing element a relatively close and wide bending zone 53 and a pleated remaining longitudinal edge section 57. The last-mentioned section 57 has a width that so is adapted that it is bent behind the gutter inner hook 19 when laying can, as shown in the final state in Figure 19. This is now a very good fixation of the sealing element in the area of the gutter. Water coming from the roof can directly into the gutter via the inner hook 19 surrounded by the sections 53 and 57 flow in, an excellent tightness is achieved because with this design prevents any water between the upper surface of the inner hook 19 and the eaves sealing element enters.

FIGS. 20 and 21 show yet another embodiment of an inventive one Eaves sealing element shown. In this embodiment, the bending zones are 63, 62 shaped as very narrow flat pleating areas to show that too such configurations are possible within the scope of the invention and depending on the installation situation are advantageously usable.

Figures 22 and 23 finally show how two individual longitudinal elements of an inventive Eaves sealing element can be advantageously connected together. In FIG. 22 shows a perspective illustration of the two longitudinal elements 70 and 80 which each have sectionally deformed bending zones 73 and 83. On her with KS designated side edges, the longitudinal element 70 and 80 have no flat deformed bending zones more on. For coupling the two longitudinal elements, for example when laying one role on the roof has ended and another role has to be worked on, the side edge regions 79 and 89 are each bent back in a U-shape upwards or downwards. The two longitudinal elements 70 and 80 are bent back with these areas brought into engagement with each other like a hook, so that a situation arises as cut in Figure 23 is shown. Due to the interlocking and wavy evenly running Pleating areas of sections 79 and 89 create a tight hook that also is still watertight. For example, you can hit it flat with a hammer and thus be further sealed and fixed.

The invention thus offers an advantageous eaves sealing technology in numerous design variants on.
