Description

The invention relates to a Seitenfalzklammer for securing roofing parts on the battens of a roof, which consists of roof battens, wherein the roof covering parts on a longitudinal side edge edge have a side fold, wherein the Seitenfalzklammer has a hook-like head portion for engaging the Seitenfalzes and a foot portion for engaging behind a roof batten, wherein the Seitenfalzklammer integrally consists of a metal strip, at the first narrow end portion of the hook-like head portion is bent and at its opposite second narrow end portion, the foot part is bent, the headboard and foot are bent in the same orientation of the metal strip, and the foot part at its rear the roof batten certain corresponding cut out of the metal strip edge has a first sharp edge or tip.

Furthermore, the invention relates to a roof covering with a battens from a A plurality of roof battens arranged transversely to a roof pitch, on the upper side of which the roof covering parts are preferably laid at the upper end area of these underside hanging humps, the upper end areas of the roof covering parts of a roof pitch direction lower row from the lower end areas of a roof pitch direction upper row of roof covering parts imbricated, wherein each roofing part further comprises a Seitenfalz at a first longitudinal edge edge and at a second longitudinal edge edge a matching hook strip, and the Seitenfalz a roofing part is hooked to the hook strip of an adjacent roofing part, each in a Seitenfalz a Seitenfalzklammer with a hook-like headboard is used and engages behind a batten with a foot, wherein the Seitenfalzklammer consists of a rectangular sheet metal strip, at the first narrow Endbe rich the hook-like head part is bent and at the opposite this second narrow end portion of the foot is bent, headboard and foot are bent in the same orientation of the metal strip, and the foot at its particular for reaching behind the roof batten, corresponding cut out of the metal strip marginal edge a first sharp edge or tip, so that the side fold clamp is hooked onto the side fold with the header and is slidable along the side fold.

Side folding clips are well known in the art. A first type of Seitenfalzklammern is complicated in terms of installation, because these brackets must be nailed or bolted to the roof battens, which brings an additional considerable workload. There are also Seitenfalzklammern second type known which are easier to install because they do not need to be nailed or screwed. This is on the DE 29814601 U1 directed. However, the known Seitenfalzklammer is consuming in terms of production, because two items must be made and assembled, which then together form the Seitenfalzklammer. It is also a disadvantage of such a Seitenfalzklammer that this is not sufficient for a secure fit of the corresponding roofing parts. Namely, if a roof equipped with such side folding brackets exerts wind suction forces which raise the roof panels at their end, this is insufficiently prevented, and moreover the effect occurs that the raised roof panels can rotate, so that the interlocking members formed on the underside of the roofing members are no longer catch behind the corresponding batten, but rest on this, so that a total displacement of the roofing parts can be done relative to each other.

A generic Seitenfalzklammer and thus secured roofing is from the DE 195 22 949 A1 known.

Based on this prior art, the present invention seeks to provide a Seitenfalzklammer generic type that can be provided at low cost, which is extremely easy to install and prevents rotation of the roofing parts under wind load.

To solve this problem it is proposed that the metal strip between the headboard and foot has a first cutout for the upper peripheral edge of a roof covering part and a second cutout for a side area of the roof lath.

The Seitenfalzklammer invention is formed from a metal strip, preferably made of sheet steel. The one-piece design of the Seitenfalzklammer leads to a cost-effective production. The sheet metal strip consists of a substantially rectangular sheet metal portion, at the first narrow end portion of the hook-like head portion is bent and at its opposite second narrow end portion, the foot part is bent. Both the head part and the foot part are bent to the same side of the metal strip out, so they protrude from the same side of the metal strip. In addition, the foot part at his particular for reaching behind a roof batten, according to the Sheet metal edge cut edge on a first sharp edge or point on.

Such a Seitenfalzklammer is extremely easy to assemble, as this only needs to be hooked on the Seitenfalz a roofing part and can be moved along the roof covering part until the foot engages behind the corresponding batten.

Since the displacement direction is parallel to the downward slope of the corresponding roof surface, the displacement of the Seitenfalzklammer is extremely simple and appropriate. In the mounting position, it is not necessary that the foot part engages in the material of the roof batten or the like, but it is sufficient if this area engages behind the batten. If equipped with such Seitenfalzklammern roofing parts are lifted by wind from the roof battens, which is quite possible with the laying direction upper end portion, which is hung with projections on a batten, this does not lead to a rotation of the plate. In this case, the first sharp edge or tip of the foot part firmly engages in the material of the roof batten. This intervention is further enhanced by the forces exerted by wind suction on the roofing panel. The fact that the sharp edge or tip is formed on the peripheral edge of the bent foot part, creates an off-center attack relative to the total extension of the Seitenfalzklammer of Headboard up to the foot part, whereby the side fold clamp is forced with its head part under load to the fold and thus keeps the upper plate parallel aligned, even if their supports are lifted off the roof batten. As a result, as the wind power decreases, the roof covering parts fall back properly onto the roof battens and can not rotate. If, as occurs in the prior art, they can rotate in the raised position, this leads to the Verhakungsnasen or the like, which are provided on the back of the roofing parts, no longer come to rest on the corresponding battens, but before come to rest, so that a misalignment of the roofing parts is the result, which is visually, but also technically undesirable.

The fact that the metal strip between the headboard and foot has a first cutout for the upper peripheral edge of a roof covering part and a second cutout for a side region of the roof batten, can be cut and formed from a rectangular sheet metal section a corresponding Seitenfalzklammer, the cutouts for the correct mounting and the desired arrangement of the foot part are helpful.

It is particularly preferably provided that the sheet metal strip is formed straight and planar.

It is quite essential that the metal strip between the headboard and footboard is straight and planar, because this ensures that between the headboard and footboard acting on the Seitenfalzklammer tensile forces can not lead by bending or stretching of the material to an extension of Seitenfalzklammer, but the Side folding clamp is dimensionally stable in itself and with corresponding loads.

Preferably, it is provided that the second cutout ends in front of the foot part, so that an approximately parallel to the peripheral edge of the foot part directed second peripheral edge has remained, which preferably has a second sharp edge or tip.

This second sharp edge or point lies in the region spanned by the metal strip, ie not in the bent foot part. It is thus formed at a distance from the first sharp edge or tip a second sharp edge or tip that should not come in the laying of Seitenfalzklammer engaged with the roof batten or the like or must come. Only when the roofing parts are subjected to wind suction, this second sharp edge or tip is also engaged on the roof lath, whereby a further obstacle is formed in order to prevent twisting of the roofing parts against the lathing.

It is preferably provided here that the second sharp edge or tip is at least slightly opposite the first sharp edge or tip.

This ensures that the second sharp edge or tip is in no way hindering the assembly and protrudes from the first sharp edge or tip, but on the contrary, it is opposite to this back, so that it is ensured that they attack only on the roofing plate wind suction forces on the batten to the system and in the roof batten penetrating the engagement comes.

In order to improve the dimensional stability of the Seitenfalzklammer still, it can be provided that the metal strip in the region of the first cutout longitudinally has stiffening beads which extend into the vicinity of the head part and the foot part.

In order to improve and ensure the desired effect of preventing the rotation of the roofing part still further, it is provided that the foot part is formed by a U-shaped turn of the sheet metal strip, the first leg is a straight extension of the metal strip and the second, the first sharp edge or tip having thighs directed parallel thereto.

The greater the distance between the first and second leg is selected by shaping the foot part, the greater the effect that is pressed by the attack of the foot on the roof battens in the case of wind suction, the clip with the head part to the fold and the top plate of Cover is kept parallel so that it can not turn away.

Preferably, it is provided that the head part is hook-like formed with two legs and that the distance between the two legs of the foot part from each other is greater than the distance between the legs of the hook-like head part from each other.

With respect to the roofing, the object of the invention is achieved in that the Seitenfalzklammer located in mounting target position with a first located between the headboard and footer neckline the upper edge of a roof mounted under a roof covering part of a top row roofing part of a lower row and engages with a second cutout engages laterally over the batten and engages with the foot behind the batten, so that the first edge or tip is arranged without contact at a small distance or with a light touch on the underside of the batten.

Through the corresponding roofing in conjunction with the Seitenfalzklammer invention is the initially asked Task solved excellently, the advantages that are given with respect to the Seitenfalzklammer, also apply to the roofing as such.

In the drawing, a Seitenfalzklammer 1 is shown for securing roofing parts 2 on the battens of a roof, the latter consists of battens 3. The roofing parts 2 have at a longitudinal edge edge on a side fold 4, wherein the Seitenfalzklammer 1 has a hook-like head part 5 for engaging over the Seitenfalzes 4 and a foot part 6 for engaging behind a roof batten 3. The Seitenfalzklammer 1 is integrally formed from a substantially rectangular sheet-metal strip, at the first narrow end portion of the hook-like head portion 5 is bent and at its opposite second narrow end portion, the foot part 6 is bent. The head part 5 and the foot part 6 are each bent in the same orientation of the metal strip, so protrude to the same side from the metal strip. The foot part 6 has at its intended for engaging behind a roof batten, according to the sheet metal strip cut edge on a first sharp edge or tip 7 on. As in the FIGS. 1a to 1f clearly visible, the sheet metal strip is straight and planar. He has between the head part 5 and foot 6, a first cutout 8 for the upper peripheral edge of a roof covering part 2 and a second cutout 9 for a side region of the roof batten. 3

The second cutout 9 ends before the foot part 6, so that an approximately parallel to the peripheral edge of the foot part 6 directed second edge edge has remained, which preferably has a second sharp edge or tip 10. This second sharp edge or tip 10 is slightly opposite the first sharp edge or tip 7. Furthermore, in the region of the first cutout 8, the sheet-metal strip may have stiffening beads along its longitudinal edge, which extend into the vicinity of the head part 5 and the foot part 6.

The foot part 6 is formed by a U-shaped bend of the metal strip, the first leg is a straight extension of the metal strip and the second, the first sharp edge or tip 7 having thighs is preferably directed parallel. The legs can also be slightly divergent or converging directed to each other. The distance between the two legs of the foot part 6 from each other is preferably greater than that Distance between the legs that form the hook-shaped head part 5.

Components of the roofing are in the FIGS. 2 to 11 shown. Roofing consists of a lathing of a plurality of transversely arranged to a roof pitch roof battens 3, are placed on the roofing parts 2, each with two at the upper end of this underside provided hanging lugs 11. The upper end portion of the roof covering parts 2, a lower row in the roof pitch direction are overlapped by the lower end portions of a top row of roofing parts 2 in the roof pitch direction. Each roof covering part 2 has a side fold 4 at a first longitudinal edge edge and a hook strip 12 matching thereto at a second longitudinal edge edge. The adjacent roofing parts of a row are hooked to the hook bar 12 each in a side fold 4 of the adjacent roofing part 2. The Seitenfalzklammer 1 is hooked in a corresponding arrangement with its head part 5 in the Seitenfalz 4 of a roof covering part 2, while the foot part 6 located in the mounting target position with the first located between the head part 5 and 6 foot section 8 the upper edge of a located under the roofing part 2, on a roof batten 3 hooked roofing part 2 overlaps. The second cutout 9 engages laterally over the roof batten 3 and with the foot part 6 behind the batten 3, so that the tip 7 or edge without touching slight distance or even with light touch on the underside of the roof batten 3 is applied. For mounting the Seitenfalzklammer 1 is placed on the side fold 4 with its head part 5 and then moved in the direction of the lower layer of roofing parts until the position is taken, as for example in FIG. 6 and FIG. 11 is shown. In the FIGS. 2 to 6 the installation situation without wind is shown. As in particular in FIG. 3 shown, is preferably only the first sharp edge or tip 7 on the roof batten 2 at.

In the FIGS. 7 to 11 is shown a situation in which wind force acts in the direction of arrow 13 on the roof covering parts 2. In this case, the Seitenfalzklammer is claimed to train, because the head part 5 is coupled to the roof covering part 2 in the region of the side fold 4 and the foot part 6 of the Seitenfalzklammer 1 engages behind the roof batten 3. In this case, not only the first sharp edge or tip 7, but also the second sharp edge or tip 10 digs into the material of the batten 3. Here, a bending moment in the direction of arrow 14 acts on the Seitenfalzklammer 1, as in FIG. 9 is shown, whereby the cohesion of the elements is promoted. This results, as in FIG. 11 illustrates that the suspension lugs 11 of each upper roofing part 2 are partially lifted from the roof batten 3. However, it is through the design and arrangement of the Seitenfalzklammer 1 ensures that the roofing part 2 can not rotate so that the in the drawing FIG. 11 upper hanging nose 11 is seated in front of the roof batten 3. When Winsoges decrease the roof covering part 2 can again in the desired position according to FIG. 6 fall back so that the proper fit of the entire roofing is ensured by the Seitenfalzklammern 1.

It is thus made available by the invention, a very easy to produce Seitenfalzklammer 1, which ensures the secure hold of the roofing parts 2 and which is very easy to assemble.

The invention is not limited to the embodiments, but in the context of the disclosure often variable.
