The shingles (3) lying next to each other in a row (R, R1, etc.) are hooked together overlapping over lateral edge strips. The upper longitudinal edges (20) of the shaped shingles (3) of a row (R1) are hooked into a latching joint (29) delimited by the substructure (4) and a profile strip (2), while the lower longitudinal edges (23) adjoin the adjacent profile strip (2 ) and overlap the upper longitudinal edges (20) of the form shingles (3) of the next lower row (R) and encompass the downward edge (15) of this profile strip (2) with flexible tongues (28).

Description

The invention relates to a cover for roofs or facades using of form shingles.

Such shingles are part of the prior art due to EP 0 674 061 B1. The material of these plate-like shaped shingles is aluminum, titanium zinc, copper or steel.

The known shaped shingles each have a substantially rectangular con figuration, with the downward narrow side rounded. Besides, is this narrow side with a lower edging directed towards the upper narrow side provided. Adjacent to the upper narrow side are two in the side Chen spaced holes through which the form shingle on a substructure, for example by nailing.

On one long side extends between the straight upper narrow side and the convex curved lower narrow side a fold with two side by side trapezoidal depressions. The bead between these two depressions In the installation position, gen is two at a distance from each other in the lower length range offset bores, which also attach the form shingle to the Serve substructure.

The opposite long side is with a simple rear-facing Provide a bevel, which is adjacent to the interior of the two depressions ten form shingle engages when the form shingles are attached to the substructure become.  

In the known case, it is necessary to assemble each individual form shingle for assembly several holes with the help of an appropriate number of nails and one Attach the hammer to the substructure. Since every form shingle for such a measure requires precise alignment and attachment a considerable manual skill. It should also be borne in mind that the Fitter not only align and hold the form shingle when fastening, but also grab the nails and use the hammer. This too requires considerable skill, especially if the Shingles form the cover of a steeper roof.

WO 95/26451 shows plate-like shaped shingles which are shaped bevels in both horizontal and vertical extension of a Badger assembled and then nailed to the substructure of the roof can be. This type of construction also requires laborious fastening of everyone Shingles, especially with regard to wind suction.

Starting from the prior art, the invention is based on the object of a To create cover for roofs or facades that are both easy to ferti and to be assembled as well as all occurring stresses, such as rain, Snow and wind, perfectly satisfying and easy to repair if necessary is.

This object is achieved according to the invention in the features of the saying 1.

Then the invention sees a complete system of profile strips and to these customized shingles. Here are the profile strips and others on the other hand, the form shingles are coordinated in terms of design so that only the profile strips on the respective substructure of a roof or facade have to be fastened, the form shingles, however, without further tools di can be non-positively coupled with the profile strips.  

The easy-to-use profile strips can be used in perfect condition without difficulty horizontal parallel alignment on the substructure. In a way, this is a precise determination of the position of the form shingles Skeleton created, on which the form shingles of only one month expensive without any aids properly at two neighboring Profile strips can be fixed in position. In addition to the associated rings The time required to install a cover is special Advantage connected that the moment of danger for the mechanic is significantly reduced is because the fitter only has the shape after fastening the profile strips must handle shingles without having to use other fasteners such as nails, Screws and hammers or screwdrivers required.

The thin-walled profile strips fulfill several functions. Since they are flawless can be attached to the substructure in parallel at a predetermined distance first, they take on a distancing function. Furthermore, they are designed in such a way that they limit locking joints in connection with the substructure zen, in which the correspondingly designed upper longitudinal edges of the form shingles can be swiveled in, in such a way that they already after hanging are secured against slipping. In addition to this locking function, the Profiles also have a trim function for the lower longitudinal edges in the next higher-lying form shingles. In this way it is ensured that the each form shingles lying one above the other overlap and Water can run off properly. In addition, the profile strips secure the molding line against lifting by wind suction forces, namely that the shape shingles in the area of their lower longitudinal edges have flexible tongues that be bent around the downward edges of the profile strips.  

The lateral edge strips of the form shingles lying in a row are interlocked so overlapping that both during initial assembly and if repair or maintenance of the area becomes necessary Chen the shingles under a cover easily in the required Number can be removed from the association and then inserted again nen.

When installing the cover, it is only after fixing the profile strips required to insert each form shingle with its upper longitudinal edge into a locking joint swivel and with its lower longitudinal edge onto the next lower profile bar reduce. Then only the tongue around the downward edge of the lower profile bar to be bent. The form shingle is then exactly posi worked.

The design of the cover from locally attached profile strips and thus form-fitting shingles that can be coupled in a positive manner allows the cover for the Principle of being able to use all roof pitches or facade surfaces.

The shaped shingles can be made of copper sheets or sheets of other dimensions materials such as zinc, aluminum, stainless steel or from galvanized or coated egg must exist. Plastic materials are also conceivable.

The material of the profile strips is in particular stainless steel or copper. Is conceivable but also aluminum or coated steel. Profiles made of these materials can be attached to substructures in the form of wooden battens are formed. Then roughened copper or stainless steel is preferred pins or wood screws used. The substructure consists in particular their profiled, z. B. trapezoidal profiled steel or aluminum strands, so the profile strips should preferably be fixed with stainless steel or copper ten carried out.  

Regardless of the design of the substructure, it can vary depending on the local Requirements be advantageous if between the profile strips and the subcon structuring a separating layer made in particular of a plastic film becomes.

The appearance of the cover is particularly appealing according to claim 2, characterized in that the width of a form shingle is larger than its in the Slope of the roof or facade is dimensioned.

A preferred embodiment of the profile strips is in the features of the claim 3 behold. Such a cross-section is in principle of any length by hand Lich, especially plumbing technology, common machines easy to reproduce ren. The locking leg extends parallel to the surface of the respective lower construction. It is fixed on this by nails, screws or rivets. On the downward longitudinal edge of the locking leg is the support web provided at an angle to the substructure. At the other end of the support web is the fixing leg in the direction of the adjacent lower profile bar folded that the fixing leg both obliquely to the locking leg as well to the top of the substructure, so that a in the longitudinal direction of the Ab Cover open locking joint for hanging the upper longitudinal edges of the molding machine is formed. On the other hand, the fixing leg with its subcon structurally facing surface of the support in the next higher row lying shingles and to fix these shingles in position on the tongues arranged at their lower edges.

The locking function of the profile strips is thereby ver further according to claim 4 improves that the fixing legs each have a step towards the substructure have fung that extends approximately centrally in the longitudinal direction of the fixing leg. Due to the gradation, each fixation leg is poured into two lengths different. The longitudinal section adjacent to the support web serves together with the Ab gradation, the support web and the substructure of the resilient latching of the  upper longitudinal edges of the form shingles, while the facing away from the support web Length section is used to attach the tongues of the shingles to it to be determined.

The curvature of the locking leg according to the features of claim 5 has the advantage that depending on the substructure and the chosen Fastening the profile strips a tilt-proof support on the substructure tion.

According to claim 6, the upper longitudinal edge of each form shingle is thereby Cross section of a locking joint adapted that the upper longitudinal edge by a two leg-shaped bend is formed. One leg extends across the bottom construction. Another leg is formed on the free end of this leg, which is at an angle to the plane of the top of the form shingle towards it extends lower longitudinal edge. The angle between the transverse leg and the free bar corresponds to the opening angle between the Support web and the inner length section of a fixing leg. The two legs current fold is positively adapted to the locking joint. The vertical leg lies on the support web and the free longitudinal edge of the bevelled leg is after the hanging on the gradation of the fixing leg. In this way is not just a resilient snap-in connection of form shingle and profile ledge guaranteed, but also a perfect protection against slipping between the form shingle and against lifting, in particular due to Wind suction forces. This backup is supported by the fact that the two legs cant bevel he essentially over the entire width of a form shingle stretches.

At the lower longitudinal edge of each form shingle is according to claim 7 to the top egg th of the shingles in the next lower row, bent downwards final strips provided. This end strip bridges in a ramp-like manner Design the distance between the lower longitudinal lying on the profile strips edges of the form shingles and the tops of the lie in the next lower row form shingles.  

The overlapping hooking of the form lying side by side in a row shingles is improved with the features of claim 8. There is an edge to this strip each form shingle between the top longitudinal edge and the bottom Longitudinal edge bent 180 ° parallel to the bottom. In this way arises the underside of the form shingle has a receiving slot open to the central transverse plane, whose width corresponds approximately to the thickness of a form shingle. On the other side the form shingle is the edge strip parallel to the top by 180 ° upwards bent over. This also makes one open to the central transverse plane of the form shingle ner slot formed with a width that corresponds approximately to the thickness of a form shingle speaks. Since the two edge strips of a form shingle are therefore opposite are bent at the bottom and top and the mouths of each formed Slits pointing towards the median transverse plane of the form shingle can be two neighboring form shingles in a row are easily hooked together the.

With the features of claim 9, the wish can be taken into account that the tops of the form shingles lying in a row all in the same ben level.

According to the features of claim 10, the tongues are only in Area around the lower ends of the parallel to the tops of the shingles curved edge strips. They are ge to the end strips through a slot separates. Since adjacent shingles over each other over these tongues overlapping the edge strips, each tongue takes over the safety at the same time tion of two adjacent shingles.

The invention is illustrated below with reference to one in the drawings Embodiment explained in more detail. Show it:

Figure 1 is a vertical schematic cross section of a portion of a cover for a sloping roof.

FIG. 2 shows an enlarged perspective view of section II of FIG. 1;

Fig. 3 in a perspective view a shingle shape of the cover of FIG. 1;

Fig. 4 is a longitudinal section through the illustration of Fig. 3 along the line IV-IV and

Fig. 5 is a side view of the illustration of Fig. 3 according to the arrow V.

In Fig. 1, 1 denotes a height range of a cover for an otherwise not shown sloping roof.

The cover 1 is composed of thin-walled profile strips 2 arranged approximately parallel to one another in a largely horizontal orientation and approximately Z-shaped cross-section and with the profile strips 2 non-positively coupled plattenarti molded shingles 3 together. The profile strips 2 consist of 1 mm thick stainless steel. The shaped shingles 3 are made of 1 mm thick copper sheet. Since several rows R, R1, etc. are formed by shingles 3 .

As can be seen when viewing FIGS. 1 and 2 together, the profiled strips 2 are fastened to a substructure 4 with nails 5 , which consists of wooden battens. Due to the Z-shaped cross section, each profile strip 2 has a locking leg 6 which can be fixed on the substructure 4 and has a slight curvature 7 which is directed away from the substructure 4 . The nails 5 are also driven through bores in the arch 7 . At the lower longitudinal edge 8 of the locking leg 6 , a flat support web 9 is attached in one piece, which it extends at an angle to the locking leg 6 and the top 10 of the substructure 4 . The width B of the locking leg 6 is approximately 1.5 times the height H of the support web 9 . The longitudinal bend 8 between the locking leg 6 and the support web 9 is slightly rounded.

At the upper end of the support web 9 , a fixing leg 11 is attached in one piece via a slightly rounded bevel 12 , which is divided into two Längenab sections 14 , 15 by an approximately centrally extending in the longitudinal direction of the fixing leg 11 gradation 13 . The support web 9 adjacent inner Längenab section 14 is bent at an angle to the support web 9 , which is greater than 90 °. In the exemplary embodiment, it is 104 °. The gradation 13 he extends largely parallel to the support web 9th The bevels 16 , 17 to the inner length 14 and the outer length 15 are rounded. The opening angle β between the step 13 and the outer longitudinal section 15 is 69 °. In this way, the two longitudinal sections 14 , 15 have different angles of inclination to the upper side 10 of the substructure 4 or to the locking leg 6 . The width B1 of the inner length section 14 is larger than the width B2 of the outer length section 15 . The ratio is approximately 1.2: 1. The ratio of the width B of the locking leg 6 to the width B1 of the inner length section 14 is approximately 1.25: 1.

By the width measurement and by the angle of inclination of the longitudinal sections 14, 15 the free longitudinal edge 18 of the outer length of portion 15 is located within a relatively ßeren distance to the top side 10 of the support structure 4 as the fold 16 Zvi rule of gradation 13 and the inner longitudinal portion fourteenth

Through the top 10 of the substructure 4 , the support web 9 , the inner Län gene section 14 and the gradation 13 , a locking joint 19 is formed with resilient compliant character.

FIGS. 3 to 5 can be clearer NEN erken the configuration of a form shingle. 3 Each form shingle 3 has a width B3 which is larger than its vertical extension E lying in the inclination of the roof.

The upper longitudinal edge 20 of each form shingle 3 is formed by a two-legged bevel 21 , 22 adapted to the cross section of the locking joint 19 (see also FIG. 1). The longitudinal edge 20 extends over almost the entire width B3 of the molded shingle 3 . A leg 21 , as can be seen in FIGS . 1 and 5, is directed perpendicular to the top 10 of the substructure 4 . At the upper edge of this leg 21 is a further leg 22 directed towards the lower longitudinal edge 23 of the molded shingle 3 . The opening angle γ between the two legs 21 , 22 is, in adaptation to the opening angle α between the support web 9 and the inner longitudinal section 14 of each profile strip 2 104 °.

The lower longitudinal edge 23 of the molded shingle 3 has a closing strip 25 which is bent toward its upper side 24 at an angle σ of 30 °. The corners 26 of the end strip 25 are rounded. The length of the end strip 25 corresponds approximately to the length of the upper longitudinal edge 20 .

In addition to the end strip 25 is a circuit strip by Ab through a slot 27 25 separate flexible tongue 28 is substantially rectangular configuration. The tongue 28 extends approximately in the extension of an edge strip 29 of the form shingle 3 , which is bent by 180 ° parallel to the top 24 . This forms a slot 30 which is open toward the central transverse plane MQE of the form shingle 3 and whose width 84 approximately corresponds to the thickness D of a form shingle 3 . The upper side 31 of the edge strip 29 is offset by a ramp-like bevel 32 parallel to the substructure 4 by an amount B, which corresponds approximately to the thickness D of a molded shingle 3 .

The other edge strip 33 of the form shingle 3 is bent through 180 ° parallel to the underside 34 . This also forms a slot 35 which is open towards the central transverse plane MQE of the form shingle 3 . Its width B4 corresponds approximately to the thickness D of a form shingle 3 .

When installing the cover 1 , the profile strips 2 are first attached to the sub construction 4 . Thereafter, the laying of the form shingles 3 in the area of the cover 1 begins at the bottom left. For this purpose, the first form shingle 3 is inserted obliquely with the upper longitudinal edge 20 into the locking joint 19 of the second lowermost profile strip 2 and then pivoted downwards until the lower longitudinal edge 23 comes to lie on the longitudinal edge 18 of the outer longitudinal section 15 of the lowest Profillei 2 . The upper longitudinal edge 20 is then embedded in a form-locking manner in the locking joint 19 . The tongue 28 is now bent according to the illustration in FIG. 5 around the outer longitudinal section 15 of the lowermost profile strip 2 . The form shingle 3 is thus fixed in position.

Thereafter, this form shingle 3 horizontally adjacent form shingle 3 as in turn over the upper longitudinal edge 20 in the latching joint 19 of the second bottom profile bar 2 , swung down and shifted in the row R relative to the already fixed form shingle 3 until that to The underside 34 of the bent edge strip 33 engages in the slot 30 of the edge strip 29 bent towards the upper side 24 . After this entanglement of the two mold shingles 3 this second form of shingle 3 can then by bending the tongue 28 about the outer Längenab section 15 of the lower profile bar 2 are fixed in position.

The remaining form shingles 3 of the cover 1 are then non-positively coupled in the same way without additional aids to the profile strips 2 in the rows R, R1, etc.
