Description

The invention relates to an arrangement for fastening of roof or facade slabs made of natural slate, art slate or similar materials on formwork, Battens or nailable masonry or other nailable surface of a building wall or one Roof, with the roof or facade panels prefabricated Perforations for the use of fasteners such as nails or the like nail-like elements or at Drive in the fastenings resulting holes exhibit.

Such an arrangement is common in the prior art and known. The roof or facade panels are so far individually by hand on the appropriate formwork (battens or the like) nailed. This manual attachment technology is very time-consuming and therefore also very  expensive. Although automatic fasteners like automatic nail setting devices or the like is known are, this technique has so far been used for fastening Roof or facade panels found no entrance. Man has already tried industrial roofs and facades slabs of artificial slate and the like with a nail attach devices, being next to that in the plate already existing through hole for the attachment medium nailed through the plate. The reason for this is that what is already in the plate Difficult to find the hole with a nailing device is. By directly nailing through the plate but these are destroyed or in particular cracks or Hairline cracks develop. The nail heads can also go through be shot or the nails won't go far enough driven so that the plates are not sufficiently firm are connected to the formwork so that they rattle can.

The same mistakes can be made with slates made of natural slate occur, with the additional risk of hairline cracks  is much larger because the natural stone is an essential has less elongation than industrial panels.

Due to the negative attempts, it is still common such roof and facade panels individually by hand nail on.

The invention is based on this prior art the task of an arrangement of the generic type Kind of creating the use of automatic Enables fasteners, where proper driving of the fasteners damage to the plates should be ensured be prevented by the automatic driving tools and the protrusion of the nail head over the view plane the slate should at most correspond to the head thickness.

To achieve this object, the invention proposes that the roof or facade panel in the area of Fastener penetration has perforations, the clear width a multiple of the thickness of the shaft  the fastener and their clear width the same or larger than the transverse dimension (Diameter) of the head of the fastener corresponds, and that in the perforation a punch and pressure-stable insert is used or can be used, in an unperforated or prepunched area from Shaft of the fastener is reachable, wherein the insert so preformed or by the head of the Fasteners when driving the Fastener is deformable so that the head of the Fasteners at most around the thickness of the head protrudes from the viewing plane of the plate or opposite this is set back in the driving direction.

The large holes in the plates can be drilled, punched or hewn. In the corresponding The insert can be punched. This Use absorbs pressures and shocks without damage, which when Fasten by semi or fully automatic driving fastener devices are caused, whereby the appropriate fasteners through the use be driven through.  

There is also a danger when driving in with a hammer blow the damage to the plate is considerably reduced since the occurring pressure and impact forces from the use can be included. Through the use of forces occurring on a larger surface on the Plate spread, causing cracking in the plate or other damage is avoided. As a result the arrangement of the insert can also be done with automatic Drive-in devices are properly driven in because excessive driving in of the fastener from can be taken up without damage. Through the relatively large-scale training of the deployment is also finding the appropriate perforation when attaching of the automatic driving-in means easier because not just a small one, the cross section of the fastener corresponding area for driving in Fastener is provided, but practical the entire area of the insert for driving the Fasteners can be used.

The use of the inventive design automatic driving tools for the fasteners  enables so that appropriate roofs or facades now semi or fully automatic plates much faster and can be attached more efficiently. The Arrangement is especially for natural slate slabs useful.

Because the perforation of the plate is larger in diameter as the regular circular nail heads is it possible to drive the nail in so far until the head is just in front of the view plane the plate is or partially or opposite this is fully sunk, using a corresponding receiving recess or the like has, which in the driving direction compared to the Visible surface of the plate is sunk into the perforation, or use when driving the nail through the head is deformable so that a corresponding set back Deepening arises. The nail head is in the Desired installation condition within the perforation of the plate preferably between those of the plate outer surfaces spanned levels.  

A preferred further development is seen in the fact that the use of the driven shaft of the Fasteners against the perforation of the perforation the roof or facade panel is kept pressed.

As a result, the position of the parts relative to each other and to the underground after driving the Fasteners still promoted. This positional security is for fixing the corresponding roof or Facade panel of crucial importance.

For the same reason, it is preferably provided that the insert and / or the perforation is designed so that when driving in the shaft of the fastener and / or when moving due to driving the insert in the hole reveal the insert radial is increasingly biased.

For even force distribution and force application To achieve, it is preferably provided that the perforation is circular.  

Under certain circumstances, it may also be preferred that the Hole reveal of the perforation conical in the driving direction of the Shaft of the fastener is tapered.

It is particularly preferably provided that the insert and arranged frictionally in the perforation.

A preferred detail is seen in the fact that the Hole diameter or cross section of the perforation approximately three to ten times the cross-sectional dimension of the shaft of the fastener corresponds.

It is also preferably provided that the insert is made of elastic material.

Alternatively, it can also be provided that the insert in the central area from rigid and only in the peripheral area elastic material.

It is particularly preferably provided that the insert is on its rear edge in the direction of use has circumferential, preferably bulging sealing lip,  the in mounting position on the outside of the roof or Facade panel, overlapping the perforated edge, is present.

This can result in the use of the rotating Sealing lip closely to the surface condition adapt to natural slate, for example a high moisture density is reached. Basically, the perforations and inserts in the Coverage areas of the plates arranged like this also with the nail penetration holes in the plates is common and known in the art.

Under certain circumstances it can also be provided that the use on the perforation or on the outer edge area of the perforation is glued.

It can also be provided that the insert on his in the direction of use, the front end of the perforation has outstanding clamping elements behind the Grab the edge of the hole, or on its out of the perforation protruding end is riveted or not flanged, whereby the rivet edge or the flanged edge behind the edge of the hole takes hold.  

It is preferably provided that the insert is made of plastic consists.

The use can also be made of other materials consist, for example, of stainless steel sheet, Aluminum sheet, copper sheet, stainless spring steel or similar. The use of plastic elements is however particularly unproblematic and therefore prefers.

It can also be provided that the use in the Perforation is molded.

For example, use in the perforation can get in the way of the injection molding process.

It is also preferably provided that the use is counter the direction of driving is arched.

This will when driving the fastener acted on the bulge, so that a uniform Tension of the insert in the perforation is reached.  

This can also cause differences in the driving depth be balanced.

A possibly preferred variant is in it seen that the insert on the shaft of the attachment is arranged by means of and with this in the perforation the roof or facade panel can be driven in.

It is particularly preferred that the head of the Fastener is less than one in diameter Corresponds to one third of the perforation diameter of the plate.

It is preferably provided that the fastening means is a nail.

It is also preferred that the insert consists of a pot-like Consists of sleeve, which with its coat on the Hole reveal creates, with its free end with the rear wall the plate is aligned or behind it has a radial flange that is level with the Sleeve bottom is formed and on the front wall of the Plate rests with the bottom including flange  preferably against the longitudinal extension of the sleeve is bulged.

Embodiments of the invention are in the drawing shown and described in more detail below.

It shows:

Figure 1 A roof or facade panel with corresponding inserts in plan view.

Fig. 2 also seen in section II-II of Fig. 1;

FIGS. 3 and 4 shows a variant in the view according to Figure 2 in different operating positions.

Fig. 5 to 18 show further embodiments in a similar representation.

The invention describes an arrangement for fastening roof or facade panels 1 , in particular made of natural slate, to a formwork of a building wall or a roof. The roof or facade panel 1 has perforations 2 in the areas in which nails or the like are to be arranged as fastening means by means of which the roof or facade panel 1 is attached to the formwork, the clear width of which is a multiple of the thickness of the shaft 3 and the head of the fastener 4 corresponds. An impact and pressure-stable insert 5 is inserted into this very large perforation, which in the exemplary embodiment according to FIG. 2 can be penetrated by the shaft 3 of the fastening means 4 in the unperforated central region. The fastening means 4 can be driven in by means of an automatic or semi-automatic device, a relatively large area being available for driving in the shaft 3 of the driving means 4 , namely the entire area of the insert 5 , which is arranged above the perforation 2 . As a result, the corresponding position is very easy to find. As a result of the arrangement and design of the impact and pressure-stable insert 5 , the automatic or semi-automatic driving-in means can act on the fastening means 4 without the risk of damaging the plate 1 .

In addition, the driving can be done so that the head of the fastener 4 is behind the plate end face or at most by the head thickness opposite the plate end face, as z. B. is illustrated in Fig. 14 or 16.

The insert 5 is primarily pressed by the driven shaft 3 of the fastening means 4 against the perforation of the perforation 2 of the roof or facade panel, as shown, for example, in the exemplary embodiments according to FIGS. 4, 6, 8, 10, 12, 14, 16. The insert 5 and / or the perforation 2 are preferably designed so that when the shaft 3 of the fastening means 4 is driven in and / or when the insert 5 is displaced in the perforation 2 of the perforation 2 due to the driving, the insert is increasingly biased transversely to the driving device, so that it is supported with its edge areas positively and non-positively on the hole reveal of the perforation 2 .

The perforation 2 is preferably circular. As can be seen in particular from the exemplary embodiments according to FIGS . 3 to 18, the hole reveal of the perforation 2 can be tapered in the driving direction of the shaft 3 of the fastening means 4 . As a result, the build-up of corresponding pressing and holding forces is positively influenced when driving in.

In the case of conical perforations 2, it may be sufficient if the area in the driving direction at the front is larger in diameter than the head of the fastening means 4 , while the perforation exit at the rear in the driving direction can be smaller in diameter than the head.

The hole diameter of the perforation 2 corresponds approximately to three to ten times the cross-sectional dimension of the shaft 3 of the fastening means. For example, the diameter of the perforation 2 can be 10 to 20 mm and the diameter of the shaft 3 2 to 3 mm. The insert 5 preferably consists of elastic material, for example plastic.

The insert can also consist of elastic or spring-elastic metal or a combination of metal and plastic. In the embodiment according to FIGS. 11 and 12, the insert 5 consists of a middle part made of hard material, which is surrounded by a sleeve-shaped elastic part.

The hole diameter is also preferably at least three times larger than the head diameter.

The insert 5 also preferably has, at its rear edge in the direction of use, a circumferential, preferably arched sealing lip 6 which, in the mounting position, as shown for example in FIG. 2, lies across the edge of the perforation 2 on the outside of the roof or facade panel 1 . To fix the insert 5 to the hole reveal, it can be glued to the hole reveal or to the outer edge area of the perforation 2 . The collar or the like of the insert 5 inserted into the perforation 2 preferably has radially projecting ribs or the like, which also ensure that the insert 5 is securely and permanently seated in the perforation 2 before the fastening means 4 is driven in. As shown in particular with reference to FIGS. 5 and 6 illustrates the insert 5 may also comprise at its front in the insertion direction end of the perforation 2 outstanding clamping members 7, which engage behind the edge of the hole or after insertion of the insert 2 crimped in the perforation or are riveted, as shown in Fig. 6. In Fig. 17 it is shown that the insert 5 can also be molded into the perforation, for example by plastic injection molding. The insert 5 can also be bulged overall against the driving direction, as can be seen, for example, from FIGS. 7 to 10 and 18.

In the embodiment according to FIG. 18, the insert 5 is arranged on the shaft 3 of the fastening means 4 and can be driven together with this into the perforations 2 in the roof or facade panel 1 . This variant is also covered by the invention.

A preferred embodiment corresponds to the representation according to FIGS. 2, 13, 14.

The insert 5 consists of a pot-like sleeve made of plastic, which rests with its jacket on the hole reveal and ends with its free end in alignment with the rear wall plane of the plate 1 . The insert 5 has a radial flange ( 6 ) in the level of the bottom of the sleeve, which lies on the outside against the end face of the plate 1 . The bottom and flange of the sleeve are bulged upwards in the drawing. Through the head of the driven fastener 4 , which is preferably a nail, the bottom of the sleeve is pushed through and pushed into the perforation 2 , so that the nail head protrudes at most by its thickness relative to the front surface of the plate 1 or even sunk into the perforation 2 can. It does not hinder the usual scale-like laying of panels 1 . Because the insert 5 is made of plastic, rattling noises between a further plate 1 resting on the insert 5 and the insert 5 together with the countersunk fastener head are also avoided. In the embodiments shown in FIGS. 1, 2, 13, 14 and 18, the respective insert 5 can be deformed by the nail head when driving it in, forming a depression, while in the other embodiments, preformed inserts 5 are provided with a depression. In both typical cases, this serves for a sunken arrangement of the nail head after driving in.

The invention is not limited to the exemplary embodiments limited, but often within the scope of the disclosure variable.

All new, in the description and / or drawing disclosed individual and combination features are considered viewed essential to the invention.
