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 an essentially rectangular configuration, the downward narrow side is rounded. Besides, is this narrow side with a lower flange directed towards the upper narrow side Mistake. Adjacent to the upper narrow side are two in the side Bores arranged at a distance from one another via 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 is a fold with two lying side by side trapezoidal depressions. The bead between these two depressions shows two in the installation position in the lower length range at a distance from each other offset bores, which also attach the form shingle to the Serve substructure.

The opposite long side is with a simple rear-facing Provide chamfer, which in the interior of the two wells of an adjacent Form shingles engage 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 have U-shaped edges Bends 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 Create cover for roofs or facades that are both easy to manufacture and is to be assembled as well as all occurring loads, 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 claim 1.

Then the invention sees a complete system of profile strips and to these customized shingles. Here are the profile strips on the one hand and on the other the form shingles matched to each other in terms of design so that only the profile strips on the respective substructure of a roof or facade have to be fastened, however, the form shingles directly without any additional tools 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 by only one fitter to any two neighboring ones without any aids Profile strips can be fixed in position. In addition to the associated reduction The time required for installing a cover is special Advantage connected that the moment of danger for the mechanic is significantly reduced because the installer only attaches the shaped shingles after attaching the profile strips must handle without using 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, they first take on a distance function. Furthermore, they are designed in such a way that they limit locking joints in connection with the substructure, into 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 supporting 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. The profile strips also secure the form shingles against lifting by wind suction forces, namely that the form shingles have flexible tongues in the region of their lower longitudinal edges, which 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 in the event of necessary repair or maintenance of areas below a cover, the shingles easily in the required Number can be removed from the association and then inserted again.

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

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 materials, such as zinc, aluminum, stainless steel or from galvanized or coated iron sheets consist. 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 pins are preferred or wood screws used. The substructure consists of in particular profiled, e.g. trapezoidal profiled steel or aluminum strands, see above the profile strips are preferably fastened with stainless steel or copper rivets carried out.

Regardless of the design of the substructure, it can vary depending on the local Requirements to be advantageous if between the profile strips and the substructure a separating layer made in particular of a plastic film is also provided 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 with craftsmanship, here especially plumbing technology, easy to reproduce conventional machines. The locking leg extends parallel to the surface of the respective substructure. It is fixed on this by nails, screws or rivets. On the downward longitudinal edge of the locking leg, the support web is rectangular protruding from the substructure. At the other end of the footbridge 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 runs to the top of the substructure, so that one in the longitudinal direction of the cover open locking joint for hanging the upper longitudinal edges of the form shingles is formed. On the other hand, the fixing leg serves with the substructure 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 further improved according to claim 4, that the fixing legs each have a gradation directed towards the substructure have, which extends approximately centrally in the longitudinal direction of the fixing leg. The gradation divides each fixation leg into two lengths. The longitudinal section adjacent to the support web serves together with the gradation, the support web and the substructure of the resilient snap-in 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 to have.

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-legged Folding is formed. One leg extends across the substructure. 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 leg corresponds to the opening angle between the Support web and the inner length section of a fixing leg. The two-legged Bending 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 connection between the molded shingle and profile strip guaranteed, but also a perfect protection against slipping the form shingle as well as against lifting, in particular due to Wind suction forces. This backup is supported by the fact that the two-legged Bending extends essentially over the entire width of a form shingle.

At the lower longitudinal edge of each form shingle is according to claim 7 to the top of the shaped shingles in the next row below intended. This end strip bridges in a ramp-like manner Design the distance between the lower longitudinal edges lying on the profile strips of the shingles and the tops of those in the next lower row Shingles.

The overlapping interlocking of the form shingles lying side by side in a row is improved with the features of claim 8. There is a border strip each form shingle between the upper longitudinal edge and the lower 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 more open towards the central transverse plane of the form shingle Slit formed with a width that corresponds approximately to the thickness of a form shingle. 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 If slots point towards the central transverse plane of the form shingle, two neighboring ones can Shingles in a row are easily hooked together.

With the features of claim 9, the wish can be taken into account that the tops of the shingles in a row are all in the same Level.

According to the features of claim 10, the tongues are only in Area of the lower ends of the bends parallel to the tops of the shingles Edge strips. They are separated from the end strips by a slot. Since adjacent shingles over each other over these tongues overlapping the edge strips, each tongue simultaneously takes over the securing two form shingles next to each other.

In Figure 1, 1 is a height range of a cover for an otherwise not called sloping roof shown.

The cover 1 is largely spaced apart from one another horizontal alignment arranged thin-walled profile strips 2 approximately Z-shaped Cross-section and with the profile strips 2 non-positively coupled plate-like 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. Thereby several rows R, R1, etc. are formed by form shingles 3.

As can be seen when viewing FIGS. 1 and 2 together, these are Profiled strips 2 fastened to a substructure 4 with nails 5, which consist of a Wooden battens exist. Due to the Z-shaped cross section, each profile strip 2 one on the substructure 4 lockable locking leg 6 with one of the Substructure 4 slight curvature 7 directed away. Through holes in the curvature 7, the nails 5 are driven. At the lower longitudinal edge 8 of the Locking leg 6 is a one-piece flat support web 9, which is at right angles extends to the locking leg 6 and to 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 is a fixing leg 11 via a slightly rounded Folding 12 is made in one piece, which is approximately in the middle in Gradation 13 extending in the longitudinal direction of the fixing leg 11 into two longitudinal sections 14, 15 subdivided. The inner longitudinal section adjacent to the support web 9 14 is bent at an angle to the support web 9, which is greater than 90 ° is trained. In the exemplary embodiment, it is 104 °. The gradation 13 extends largely parallel to the support web 9. The folds 16, 17 to the inner Length section 14 and the outer length section 15 are rounded. The Opening angle between the gradation 13 and the outer longitudinal section 15 is 69 °. In this way, the two longitudinal sections 14, 15 different angles of inclination to the top 10 of the substructure 4 or to Locking leg 6. The width B1 of the inner length section 14 is larger than that Dimension width B2 of the outer length section 15. The ratio is about 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.

Due to the width dimensioning and the inclination angle of the length sections 14, 15, the free longitudinal edge 18 of the outer longitudinal section 15 is larger Distance to the top 10 of the substructure 4 as the fold 16 between the gradation 13 and the inner length section 14.

Through the top 10 of the substructure 4, the support web 9, the inner length section 14 and the gradation 13 becomes a locking joint 19 with resilient Character formed.

Figures 3 to 5 clearly show the design of a molded shingle 3. Each form shingle 3 has a width B3 which is greater than its inclination vertical dimension E of the roof is dimensioned.

The upper longitudinal edge 20 of each form shingle 3 is by a to the cross section of the Locking joint 19 (see also Figure 1) adapted two-leg chamfer 21, 22 formed. The longitudinal edge 20 extends over almost the entire width B3 Form shingle 3. One leg 21, as can be seen in FIGS. 1 and 5, is vertical directed to the top 10 of the substructure 4. To the top of this Leg 21 closes to the lower longitudinal edge 23 of the molded shingle 3 directed further leg 22 on. The opening angle between the two Legs 21, 22 is adapted to the opening angle 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 one on its upper side 24 at an angle of 30 ° bevelled end strips 25. The corners 26 of the End strips 25 are rounded. The length of the end strip 25 corresponds approximately the length of the upper longitudinal edge 20.

In addition to the end strip 25 there is a through a slot 27 of the end strip 25 separate flexible tongue 28 approximately rectangular configuration. The tongue 28 extends approximately in the extension of an edge strip 29 of the molded shingle 3, which is bent parallel to the upper side 24 by 180 °. This will be a to the central transverse plane MQE of the form shingle 3 open slot 30 formed Width B4 corresponds approximately to the thickness D of a form shingle 3. The top 31 of the Edge strip 29 is by a ramp-like bevel 32 by an amount B. offset parallel towards the substructure 4, which is approximately the thickness D corresponds to a form shingle 3.

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

When installing the cover 1, the profile strips 2 are first on the substructure 4 attached. Then the laying of the shingles 3 in the area cover 1 started at the bottom left. For this purpose, the first form shingle 3 with the upper longitudinal edge 20 in the locking joint 19 of the second lowest profile strip 2 inserted obliquely and then pivoted downwards until that the lower longitudinal edge 23 on the longitudinal edge 18 of the outer longitudinal section 15 of the lowest profile strip 2 comes to rest. The upper longitudinal edge 20 is then positively resilient in the locking joint 19 embedded. Now the tongue 28 according to the illustration of the Figure 5 bent around the outer longitudinal section 15 of the bottom profile bar 2. The form shingle 3 is thus fixed in position.

Then the shingle 3 horizontally adjacent to this form shingle 3 in turn over the upper longitudinal edge 20 in the locking joint 19 of the second lowest profile strip 2 hung, pivoted down and so far in the row R relative to already fixed form shingle 3 until the bent over to the bottom 34 Edge strip 33 in the slot 30 of the edge strip bent towards the top 24 29 takes hold. After this interlocking of the two form shingles 3, this can also be done second form shingle 3 by bending the tongue 28 around the outer longitudinal section 15 of the lower profile bar 2 are fixed in position.

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