Definitions

the invention relates to a strip-shaped device for Covering of a longitudinal gap between the roof a ridge or ridge plank and roofing slabs according to the preamble of claim 1.
Such a device is a sealing apron from the European Patent No. 0 389 058 B1 known.
This The sealing apron has a fastening part for fastening on a flat roof part and a cover part, at least is partially corrugated and its corrugated part resiliently deployable material, the height of the corrugations from the outer edge of the cover part in Direction to the mounting part decreases and the cover part free of thick support devices and in one piece with the Fastening part is formed.
Another ridge or ridge ventilation element for pan roofs is from the German patent DE 40 01 766 C2 known.
a rollable element is described which has a wavy cross section of its side parts which is thermally or mechanically molded, with the side parts glued to the underside with which they are attached to the roofing panels be attached.
the disadvantage is that with the Formation of the waveform in a nonwoven manufacturing this ventilation element complex and expensive. It is also absolutely necessary to put the side panels in glue the profiling of the roofing slabs there the fleece fan itself does not have any Gasket supporting compressive force against the roofing panels can exercise.
a strip-shaped device for covering a along Roof-running gap between a ridge or Burr and roofing slabs to create the overcomes the above disadvantages of the prior art.
such a device is to be created are manufactured that are relatively inexpensive and inexpensive can be and still have good sealing properties Has.
This task is accomplished by a strip-shaped device solved according to the characterizing part of claim 1 is designed.
the main advantage of the device according to the invention lies in the stiffness they have at the transition from the ventilation section to the adjacent side panel. Through this Stiffness creates a spring effect that over the Ventilation sections from the support to the side panels the device acts and causes these side parts with a sufficiently large force effect, i.e. enough great pressure in the profiling of the roofing slabs and are pushed into their valleys.
the pleating of the side parts and their towards their outer edge decreasing material thickness support a complete and enough strong pressure and a good one Sealing on the edges of the side parts.
a structural reinforcement is provided by the fact that the Height of the pleating essentially from the ventilation sections towards the outer edges of the side panels stays the same.
the pressure created by the spring action can because of this wave structure well up to the edges of the Side parts are passed on, with no or only slight deflection of the side parts around the longitudinal axis of the Device arises.
For the lateral rigidity of the side parts in the area of the transition from the ventilation section to Side part are the provided reinforcement devices decisive.
Device has these spaced in the longitudinal direction Spacers, preferably in the transition area from the ventilation section to the adjacent side part are arranged above, and essentially to it serve to prevent lying on the device Components block the ventilation paths.
the reinforcement devices can each be in the Area of these spacers can be arranged, which means adjust the reinforcing spring action in this area becomes. But it is also possible to use a variety of reinforcement devices between the spacers to provide sufficient rigidity put. To further increase the stiffness of course also the possibility in the area of Spacers as well as reinforcement devices between them to place.
the strip-shaped device In one configuration of the strip-shaped device according to the present invention, it is characterized in that that the distances of the reinforcement devices in Longitudinal direction of the strip-shaped device of the division the waveform formed by the roofing tiles correspond.
the spring action at the transition between the Ventilation section and the side part is in places particularly important where the edges of the pleated apron come in the troughs of the profiled roofing slabs have to immerse. That is why it is important to create one according to the invention To design the device, or the reinforcement devices in the division so close together that also for the valleys of the roofing slabs there is sufficient rigidity, so also ensure tightness at the edges.
the strip-shaped device can thus according to predetermined Divisions of the waveform of the roofing panels optimal be designed.
the reinforcement means from the top of a spacer on the outside of this and on The side panel runs out into the pleated side panel Reinforcing ribs and preferably also across additional ribs running over the ventilation section.
the reinforcement ribs running over the spacers, which extend to the top of the spacer can guarantee an improved in this area Stiffness. This is especially true when this embodiment is designed so that the reinforcing ribs in the apex of an outwardly curved pleating section leak.
This variant preferably takes the one according to the invention Device the depth of the reinforcement ribs from Top of the spacer from up to her in the The apex of an outwardly curved pleating section end steadily ending.
the areas of the Side part supported by the reinforcement ribs which is a greater depth in this area are very good in their Lateral stiffness supported.
These reinforcement inserts arranged on the inside can be used in addition to the reinforcement ribs on the outside or as the only one Stiffeners can be arranged inside.
reinforcement ribs and reinforcement inserts both inside and out are provided at and between the Spacers are arranged.
An advantageous education the reinforcement inserts is through the transition area on the edge between the side part and the Ventilation section bridging, essentially triangular Ridges accessible.
a strip-shaped according to the invention Device in one piece using an injection molding technique to be manufactured.
This type of production is a ensures inexpensive and inexpensive production, compared to extrusion and deep drawing processes Making the raised contours possible.
the invention Thermoplastic device, especially a polyolefin.
the device Made of a polypropylene material with additives for improvement the resistance to UV light and the increase the elasticity of the pleated side panel.
the device Made of a polypropylene material with additives for improvement the resistance to UV light and the increase the elasticity of the pleated side panel.
the amount of pleating measured by Wellenberg too Troughs can be about 2 mm to 10 mm, in particular 4 to 8 mm and particularly preferably 5 to 7 mm. It is from the demands on the elasticity of the pleated Depend on the side part and is therefore in height on the different profiles of the roofing body, such as Example brick, adjust.
the material thickness of the side parts on the outer edges should be about 0.2 mm to 0.6 mm, especially 0.3 mm to 0.5 mm, while the material thickness of the side parts on Transition to the ventilation sections about 0.5 mm to 1.5 mm, in particular 0.8 mm to 1.2 mm. It is to ensure that according to the invention the material thickness on Transition to the ventilation sections is larger than at the outer edges of the side panels.
the specified values can be a well-sealing strip-shaped device produce the because of their lower material thickness on the outer edges there a good sealability and Has elasticity and with its higher material thickness in the transition area between the side part and the ventilation section good rigidity or spring action enables.
the pleated side parts preferably have one spread-apart form, which in particular consists of converging Circular arcs, trapezoidal shapes, angular shapes or U-shapes is built. However, there are all conceivable here spreadable shapes can be used.
the device is characterized in that the pleated side panels across the waveform or in Vertical direction of the pleated spring ribs exhibit. Depending on their education, they can Strengthen the internal spring stiffness of the pleated side parts and improve. When attached along the apex line Spring ribs can thus apply pressure to the roof tiles be further improved while in the transverse direction, e.g. under the crown at the edge of the pleated side part attached spring ribs this a kind of leaf spring effect to strengthen the structure.
an inventive one strip-shaped device can be rolled up by the meter be designed to be installable.
Strips with lengths of 5-10 meters are made, the made from the endlessly manufactured product are.
a preferred method of making such Strip is the extrusion process.
FIG. 1 shows the essential parts of a ridge with an assembled strip-shaped according to the invention Device which is further referred to as ventilation strips 1 should be designated.
the ventilation strip 1 is with its support 11 on the upper surface of a ridge plank 2 attached lengthways along the roof, for example nailed. Between the ridge plank and the top edges the roofing tile 3 runs a gap along the Roof, which are covered by the ventilation strip 1 got to. This gap is essentially from that to the Pad 11 adjacent ventilation section 12 of the ventilation strip 1 bridges, in which case by Vents 14 sufficient air passage from Area below the ventilation section 12 to the area below the ridge tile 4 is guaranteed.
the Side parts 20 of the ventilation strip 1 shown the from the edge of the ventilation section 12 to their formed in the valleys of the roof tiles 3 outer edges extend.
the side parts 20 are in this example wavy pleated from the connection to the Ventilation section 12 to its outer edges in same height. The pleating leads to the Profile of the roof tiles 3 so that the side parts 20th spread out at their outer edges and closely to the profile put on the roof tile. This will seal against penetrating liquids and snow guaranteed.
the ventilation strip 1 described here consists of a polypropylene material with additives for improvement the resistance to UV light and the increase in Elasticity of the pleated side part 21 (see figure 2).
a polypropylene material with additives for improvement the resistance to UV light and the increase in Elasticity of the pleated side part 21 (see figure 2).
another thermoplastic in particular a polyolefin can be used.
the ventilation strip 1 shown in the figures has to improve the transverse rigidity at the transition between the ventilation section 12 and the side part 20 both reinforcing ribs attached to the outside of the spacers 13 22 as well as inside in this transition area reinforcement inserts 23 (see FIGS. 2 and 3).
These reinforcing devices 22, 23 are along of the ventilation strip 1 arranged so that they have a optimal pressure of the side parts especially in the areas provide where the apron is in a trough of the Insert profiled roofing slabs or tiles 3 got to.
the longitudinal distances between the reinforcing ribs 22 and the reinforcing inserts 23 dimensioned so that they Division of the waveform formed by the bricks 3 correspond.
the reinforcing inserts 23, 22 should do this have a correspondingly narrow division.
FIG. 2 shows a cross section through the ventilation strip 1 at a point where reinforcing ribs 22 for Improvement of transverse rigidity are appropriate.
the Ventilation strip 1 is shown with respect to the Center line symmetrical and has the support in the middle 11, which in the assembled state of the ventilation strip 1 comes to rest on the ridge screed 2 (see FIG. 1) and is attached. Closes slightly rising each on the side edges of the edition 11 Ventilation section 12 in which the ventilation openings 14 (not shown here, see Figure 1).
the spacers 13 are shown here, the top protrude from the edges of the ventilation sections.
the side part adjoins the ventilation section 12 20, which is pleated in its lower section Side part 21 is formed.
the side part 20 has on Connection area to the ventilation section 12 a material thickness from 0.8 to 1.2 mm on while it is on its outer edge 24 is only about 0.3 mm to 0.5 mm thick. Due to this difference in material thickness, this can pleated side part 21 on the outer edge 24 very well expand and thus optimally fulfill the sealing function.
the ventilation strip must be in the transition area between ventilation section 12 and side panel 20, however A sufficiently high transverse rigidity also along the side part 20 exhibit.
FIG. 2 there is now also the further one Reinforcement rib provided to increase this transverse rigidity 22 shown. It extends from the top of the Spacer 13 to the beginning of the pleated section 21 of the side part 20. In the example shown she runs into the crown of an arched outward Pleating section.
the depth of the reinforcement rib 22 takes from the top of the spacer 13 to Connection to the pleated side panel 21 steadily, and so causes the spring force in the transition area between the ventilation section 12 and the side part 20 arises, is optimally passed on to the side part 20.
the amount of pleating corresponds to approximately 5 in this exemplary embodiment up to 7 mm. With a pleating with this height can by the structure-strengthening effect of the spring force is optimal be passed up to the sealing edges 24.
FIG 3 shows a cross section through a Ventilation strip 1 according to the invention, the one place is placed where there are reinforcement inserts arranged in the inner part 23 are located.
the structure of the ventilation strip 1 3 is essentially the same as in FIG 2.
In contrast to Figure 2 are in this section essentially triangular reinforcement inserts 23 inside in the transition area between the ventilation section 12 and the side part 20 attached.
the reinforcement inserts 23 stiffen the transition area 12, 20 also here in the area of a spacer 13, see above that also at this point a sufficient pressure force of the Side part 20 is present on the roof tiles 3 when the Ventilation strips with its support 11 on a ridge plank is attached, i.e. if the pleated ones Side panels 21 in the profiled roofing panels insert.
Figures 2 and 3 are only cuts on the Spacers 13 shown.
the described preferred However, embodiment has depending on the stiffness requirement also between the spacers 13 reinforcing devices such as reinforcing ribs 22 or reinforcing inserts 23 on.
Figure 4 shows a cross section, as in the figure 2 is shown, with the difference that here additional extending across the ventilation section 12 Additional ribs 22a are shown, which Stiffness of the transition area from the ventilation section 12 to the side part 20 further increase, and thus for one ensure even better tightness of the ventilation strip.
the longitudinal arrangement of the additional ribs 22a can be that of Reinforcing ribs 22 correspond, but there is also Possibility of a plurality of additional ribs 22a Strengthening of the spring action along the ventilation strip 1 to be attached at any desired location.
FIG. 5 shows a cross section through the ventilation strip according to that of Figure 3, with additional here attached, running transversely under the ventilation section Additional inserts 23a are shown.
the additional inserts 23a provide one further improve the stiffness in the transition area from the ventilation section 12 to the side part 20.
the arrangement of the additional inserts 23a along the ventilation strip 1 only by stiffness requirements given, d. H. they can both be arranged in places be on which there are also reinforcing inserts 23, but also as a multitude with and between them.
Figure 6 is a cross-sectional view of a side part (20) in the apex direction of the pleating, in which one Spring rib (30) is visible. This runs along the apex of a pleating section (21) and thus reinforces its rigidity against deflection. Another effect of this spring rib (30) is in that the pressure of the side parts (20) the roof tiles very well to the outer edge (24) of the pleated sections (21) can forward.
Such Spring ribs (30) on each pleating section in particular be arranged at each vertex.
FIG. 7 shows a perspective sectional view, at the one under the top of the pleating, across Spring ribs (31) extending to the apex direction are shown are. These act as a further structural reinforcement and exert a leaf spring effect, being a very good one Preload of the pleated sections (21) can be achieved can.
