Description

FIELD OF THE INVENTION

The present invention relates to a roofing device and a method for producing such a roofing device.

TECHNICAL BACKGROUND

Roofs are used for a wide variety of applications. A frequently encountered type of roofing represent so-called terrace roofing.

Although the present invention and the problem underlying it are described below with reference to a patio roof, they are not limited thereto but transferable to a variety of types of roofing devices.

Terrace roofs often have a trained as a wall connection profile side rail profile, which is anchored with fastening means, such as bolts, on a wall. Due to structural or local conditions, a mounting height of such a wall connection profile may vary. On a side facing away from the wall, the patio roofing is usually stored with a Pfette supported by posts. All these components are usually prefabricated parts, which are pre-produced in standard sizes. It is thus desirable to be able to vary during assembly a pitch angle of the rafters, which results from the mounting height of the wall connection profile and the height of the posts, in order to be able to react easily to structural or local conditions.

With a variability of the angle of attack of the rafters, there is also the need for variability of the angle of attack of the roof panels or infills, which are usually mounted on the rafters.

The publication US 4,998,389A describes a roof system which is provided with a wall connection. To a wall connection profile wall connection fittings are provided which have a circular cylindrical recess. A rafter holder has a corresponding Sparrenhalterbeschlag, which has a recordable in the recess circular cylinder. Furthermore, the rafter holder fitting has a closure flange. In this way, the Sparrenhalterbeschlag is in a horizontal position on the wall connection fitting on and off. If a rafter holder fitting is pivoted into an angular position, the closure flange engages under the wall connection fitting so that the rafter holder is secured therein. A roof panel lies here on the rafters. For sealing a separate web is provided on the wall connection profile, on which a pending on the roof panel seal is provided.

The disadvantage is not completely free in the choice of the angle of attack of the rafters in the assembly with such a system, since a minimum inclination is necessary to ensure a backup through the closure flange. Furthermore, here, the web or the seal must be designed for sealing the roof panel to the desired angle or adjusted during assembly.

The applicant has this in the DE 20 2016 005 196 U1 described solution which provides locally limited to the longitudinal beam profile of a roofing device in the longitudinal direction an insertion section on which a trained for receiving a rafter holder bearing profile section is so excepted that it can be inserted for mounting in a Umgreifabschnitt the rafter holder. In this way, a positive connection between the side member profile and rafter holder can be produced by longitudinal displacement.

In the installation of patio roofs, a longitudinal dimension with which rafter holders of adjacent rafters are spaced apart is determined by the width of the infill, for example in the case of glass through the width of the glass panes. This measure is usually provided with a thermal expansion clearance and the rafter holder positioned in the longitudinal direction accordingly. The rafters are then successively mounted gradually and the infill measured and used therein. In this process, therefore, add up the manufacturing and Einmesstoleranzen along the canopy adversely. Accordingly, the degree of a last infill, which is used last during assembly, must be adapted to the remaining length of the side rail profile. For example, the last infill, especially in the case of glass, the last glass pane and a glass bar attaching the pane, may be too short if too little draft air has been left. In this case, bridging pieces would have to be used or new parts made. Otherwise, the infill, in particular a glazing bead or possibly also the last pane, may be too wide if too much expansion air has been left.

Accordingly, it is provided:

• - A roofing device, in particular terrace roofing, comprising: a side rail profile, which is designed for mounting a rafter holder and has a bearing profile section; a rafter holder for holding a rafter on the side rail profile, wherein the rafter holder has a corresponding to the bearing profile section Umgreifabschnitt which is designed for positive storage on the bearing profile section, wherein the longitudinal carrier profile in the longitudinal direction locally limited an insertion has, on which the bearing profile section is so excluded that it is insertable for mounting in the Umgreifabschnitt of the rafter holder, wherein the Umgreifabschnitt is formed longitudinally displaceable on the bearing profile section and by longitudinal displacement a form fit between the Umgreifabschnitt and the bearing profile section is produced, and wherein at the Umgreifabschnitt of the rafter holder a locking means and on the bearing profile section of the side rail profile a longitudinally offset counter-locking means is provided which is offset in the longitudinal direction relative to the insertion section and which is provided by longitudinal displacement of the Um gripping portion are formed on the bearing profile section engageable with each other.
• A method for producing a roofing device, in particular a roofing device according to the invention, comprising the steps of: providing a side rail profile for receiving a rafter holder, which has a bearing profile section, and a rafter holder for holding a rafter on the side rail profile, which has a encompassing section corresponding to the bearing profile section, wherein on the Umgreifabschnitt of the rafter holder a locking means and on the bearing profile section of the side rail profile is provided a longitudinally offset to the insertion arranged in the longitudinal direction counter-locking means; Inserting the bearing profile section into the gripping section in the region of an insertion section provided locally in the longitudinal direction on the side rail profile; Producing a positive connection between the Umgreifabschnitt and the bearing profile section by longitudinal displacement of the Umgreifabschnitts relative to the bearing profile section; and producing a longitudinal securing of the Umgreifabschnitts to the bearing profile section by means Bringens the latching and counter-latching means by the longitudinal displacement of the Umgreifabschnitts on the bearing profile section.

The finding underlying the present invention is that the addition of manufacturing and Einmesstoleranzen in the assembly of a roofing device by a longitudinal securing of rafter holders at predetermined locking portions is avoidable.

The idea of the present invention is based on providing a latching means on the gripping section of the rafter holder and on the bearing profile section of the side rail profile at predetermined latching sections in the longitudinal direction counter-locking means, which automatically engage with each other by longitudinal displacement in the production of the positive locking. In this way, all Längsjustagearbeiten be avoided in the assembly of a roofing device. Furthermore, thermal expansion joints are already factory-set in their dimensions, so that the hitherto customary step of measuring a infill with a suitable expansion joint is eliminated. In this way, according to the invention, all infillings of the roofing device can be provided with the right amount from the outset or at the factory, so that in particular no adaptation of a last infill is required any more.

In summary, a fitter according to the invention in the positioning of rafter holders no longer needs to worry about the attachment and dimensional stability, in particular no longer about the error-prone measuring of expansion joints. Instead, the necessary expansion air is already predetermined by the assembly technique according to the invention.

In addition, an installer does not need the rafter holder, as previously customary set by additional fasteners on the side rail profile. Instead, the correct and already adapted to the intended infill mounting position according to the invention is determined by the appropriate prefabrication of the latching and counter-locking means and the longitudinal securing at the correct location automatically achieved by the interlocking of the latching and counter-latching means.

For assembly, the fitter therefore only needs to use the rafter holder on the insertion section and move it in the longitudinal direction until it engages with the latching and counter-latching means. The installation of a roofing device is thus inventively much easier, safer, faster and less prone to failure. In particular, a very high level of occupational safety for assembly is also provided, since the once used rafter holder can no longer unintentionally move out of the side member profile after longitudinal displacement.

The side rail profile may have different configurations, for example, it may be formed as a wall connection profile or as a purlin.

As Sparrenhalter is any kind of suitable for holding a rafter on a side rail profile training.

As Umgreifabschnitt is a section of the rafter holder to understand, which is suitable for gripping the bearing section profile. The bearing profile section is gripped at least partially, in particular at least on two opposite sides, in such a way that there is a positive pivotable coupling of the rafter holder to the longitudinal carrier profile.

A longitudinally locally limited insertion section is understood to mean a local recessed section which does not extend over the entire length of the side rail profile but only over a comparatively small part or section of the length of the side rail profile. The width of the insertion is wide enough to introduce the locally except bearing profile section in the Umgreifabschnitt the rafter holder. The insertion portion thus has a width that is wider than the encompassing portion of the rafter holder. For example, it can be a width of the insertion section in the range of one to two times the width of the rafter holder.

The counter-locking means is arranged offset in the longitudinal direction to the longitudinally locally limited insertion, that a sufficient, preferably a complete, support of the Umgreifabschnitts is ensured on the bearing section section.

Incidentally, the side rail profile is formed in the longitudinal direction, in particular with a constant cross-sectional shape. In this case, the bearing profile section is a section of the side member profile extending linearly, with the exception of the recess and the counter-locking means, with a constant cross section.

The production of a positive connection is made in particular by moving the rafter holder in the longitudinal direction of the longitudinal carrier profile out of the insertion section, that is to say in particular into a region without a recess of the bearing profile section.

The bringing into engagement of the locking means and counter-locking means can be carried out simultaneously with the production of a positive connection. In particular, the counter-latching means may be positioned on the bearing profile section in such a way that the latching and counter-latching means engage with one another when a complete positive connection has been reached. Are the latching and counter-latching means engaged, the rafter holding is locked or secured in the longitudinal direction of the bearing profile section.

The method for producing the roofing device is in particular a mounting method or a method for mounting a roofing device.

Advantageous embodiments and further developments will become apparent from the other dependent claims and from the description with reference to the figures of the drawing.

According to an advantageous embodiment, the latching and counter-locking means for longitudinal securing of Umgreifabschnitts are formed on the bearing profile section. Advantageously, therefore, no additional or manual longitudinal securing of the rafter holder needs to be made.

According to a preferred embodiment, the latching and counter-latching means are formed rotatable to each other, so that the Umgreifabschnitt is pivotable in a latched state about the longitudinal axis of the bearing profile section. In this way, a desired roof pitch can be adjusted freely and continuously.

In a further development of the Umgreifabschnitt is pivotable in a locked state by a predetermined angle about the longitudinal axis of the bearing profile section. In particular, a pivoting is provided by an angle which is between 10 ° and 45 °. Such an angle is preferably between 15 ° and 35 °. A particularly preferred angle is between 25 ° and 30 °.

According to a further development of the Umgreifabschnitt is pivotable in a latched state by a predetermined angular portion of a position of the rafter holder relative to the side rail profile about the longitudinal axis of the bearing profile section. In particular, the pivoting is provided at an angular position of the rafter holder to the side rail profile between -10 ° and 45 °. Such an angular position is preferably between 0 ° and 35 °. Particularly preferably, a Angle position in the range between 3 ° and 30 °.

According to an advantageous embodiment, the latching and counter-latching means are formed by exceeding the predetermined angle detachable. Alternatively or additionally, the latching and counter-locking means are formed by exceeding the predetermined angle portion releasably. Advantageously, in this way without intervention of the engagement between the locking and counter-locking means are also solved without destruction, for example, for disassembly of the roofing device.

According to one embodiment, the locking means and the counter-locking means are formed with a resilient pressure piece and a circumferential groove corresponding thereto. The pressure piece can be arranged for example in a transversely extending to the longitudinal axis threaded bore in the Umgreifabschnitt. The circumferential groove may extend over a portion of the lateral surface of the bearing profile section. In particular, the circumferential groove describes an angular section about the longitudinal axis of the bearing profile section. In the longitudinal direction, the circumferential groove is preferably formed with a thickness corresponding to the pressure piece.

According to an advantageous development, the circumferential groove runs at at least one end with a slope. The pitch is designed so that the pressure piece can be pressed out by exceeding the predetermined angle of rotation and / or the predetermined angle portion of the circumferential groove for releasing the latching and counter-latching means. If the pressure piece is formed with a round head, the pressure piece for releasing can only be largely pushed out of the groove and the remaining spring force can be overcome in a longitudinal displacement by means of the round shape. Advantageously, the spring force of the pressure piece always counteracts loosening, so that a certain resistance is provided, which avoids unintentional or automatic loosening. Further advantageously, no tools are needed to solve. In addition, the release is possible non-destructive.

In a further embodiment, a groove profiling the bearing profile section would also be conceivable as a counter-locking means. Advantageously, such a secant cutting groove in the case of a cylindrical bearing profile section automatically to an obliquely extending to the lateral surface groove bottom, so that here at the outlet of the groove does not need to be provided extra slope. Of course, it depends on the material thickness or design of the bearing profile section, whether a bearing profile section sekantenartig cutting groove from the perspective of statics questioned.

According to one embodiment, the latching means is formed with the arranged in the Umgreifabschnitt pressure piece and the counter-latching means with the introduced on the bearing profile section circumferential groove. The pressure piece can be screwed, for example, in a provided in the Umgreifabschnitt threaded hole. The circumferential groove can for example be automatically milled in the region of the bearing profile section. Advantageously, the latching and counter-locking means are thus easy to manufacture.

According to one embodiment, the counter-locking means is arranged in a locking position of the bearing profile section which predetermines a mounting position of the rafter holder in the longitudinal direction. The latching and counter-latching means are engageable by longitudinal displacement of the Umgreifabschnitts on the bearing profile section of the insertion section to the latching portion with each other. In particular, the latching portion can be dimensioned to achieve a complete positive connection between the Umgreifabschnitt and the bearing profile section and accordingly has unprocessed portions of the bearing section section. The dimensioning of the latching section is preferably provided such that the latching and counter-latching means come into engagement with each other when the complete positive connection is reached.

According to one embodiment, the insertion section is arranged directly next to the latching section. In particular, the latching section directly adjoins the insertion section. Advantageously, the necessary for assembly longitudinal displacement is reduced to only necessary for the production of the desired positive fit degree in this way.

According to one embodiment, the latching section is associated with two insertion sections, which are arranged on both sides next to the latching section. In this way, the assembly can be made as appropriate to the installation situation or accessibility from both sides.

According to an advantageous embodiment, the bearing profile section has a cross-sectionally at least partially round profile. The Umgreifabschnitt has a corresponding at least partially round recess. In particular, the bearing profile section is at least partially circular cylindrical and the recess correspondingly also at least partially circular cylindrical. Advantageously, a sliding together of the bearing profile section and the Umgreifabschnitts allows by the round design, so that an angle of attack is adjustable.

According to one embodiment, the encompassing section has one in the at least sections Round recess projecting bore, in particular threaded bore, on. In the hole, the locking means can be fastened. In particular, it may be a pressure piece, which is resiliently received in a provided with an external thread sleeve. In this way, the locking means in the prefabrication of a roofing device in a desired position on the Umgreifabschnitt can be positioned. Particularly advantageous positioning does not need to be changed due to the lack of training during assembly. This represents in particular a great advantage over a threaded pin previously often used for fixing.

According to an advantageous embodiment of the bearing profile section is formed umgreifbar in a circumferential angle of greater than 180 °. In particular, it is designed to be encompassable in a circumferential angle of at least 270 °, preferably 280 ° to 300 °. Advantageously, in this way a large pivoting range between the side rail profile and rafter holder allows.

According to a preferred embodiment, the gripping portion is formed to engage around the bearing profile section in a circumferential angle greater than 180 °. In this way, a positive engagement with the bearing profile section is made possible only by the shape of Umgreifabschnitts. In an advantageous embodiment, the circumferential angle is greater than 200 °, preferably formed between 210 ° and 260 °, more preferably between 230 ° and 250 °.

In accordance with a particularly preferred embodiment, the bearing profile section can be grasped in the longitudinal direction away from the insertion section by the encompassing section in such a way that, while maintaining the positive locking, the rafter retainer can be pivoted into a positive position and into a negative position relative to the longitudinal carrier profile. Under a positive employment is to understand a job in which a mounted on the rafter holder rafter from the side rail profile extends down. A negative employment is accordingly to be understood to mean an employment in which a rafter mounted on the rafter holder runs upwards from the side member profile. Advantageously needs in this way for both types of employment no structural change of the supporting components are made.

According to one embodiment, a pivoting range of the setting is at least 0 ° to + 30 °. Also conceivable are pivoting ranges from 0 ° to + 45 °. Advantageously, in this way, especially for patio roofs, usual angle of attack covered by the pivoting range.

According to one embodiment, the side member profile is designed as a wall connection profile. In the assembled state, the employment is adjustable relative to a wall. Under a wall is to understand any type of suitable for attaching the wall connection profile building. It may, for example, be a masonry wall, a wooden wall, a facade, a frame, a truss or the like. In particular, the wall is a vertical wall. However, it is also conceivable to use a sloping wall or facade.

According to a further embodiment, the side rail profile is designed as a purlin profile. In the assembled state, the employment is thus adjustable relative thereto. In particular, the purlin profile may be provided or formed in the form of a ridge purlin. Advantageously, the roofing device can be installed in this way without a wall connection. In particular, the purlin is oriented at a vertical, so that the angle of attack with respect to the vertical is aligned.

According to one embodiment, the side member profile on each side on a bearing profile section. In this case, opposing rafter holders are receivable in the side rail profile. This embodiment is provided in particular in a trained as a ridge purlin side rail. Advantageously can be realized in this way with a common side rail profile on two opposite sides of the side rail section a canopy. In particular, such a side member profile with a bearing section on both sides may be two interconnected one-sided side member profiles. For example, two provided for wall connection side rail profiles can be connected to each other on their sides, so that a common profile is created with two-sided bearing profile sections. Advantageously, the variety of components is reduced in this way, so that the production is simplified.

In an advantageous embodiment, a purlin, in particular in the form of a foot purlin, is provided on an end of the rafter opposite the rafter holder. The purlin has a round bearing extension. In particular, this is designed in the form of a circular cylinder profile section. The rafter has a corresponding receiving extension, which is designed in particular in the form of a claw with a circular-cylindrical section-shaped recess. The recording extension is designed to encompass the circular bearing extension. In particular, the assembly of the round bearing extension takes place with the receiving extension to produce a positive connection, preferably by longitudinal displacement of the recording extension on the Circular bearing extension. Advantageously, a pivotable articulated in a large range pivotal connection of the purlin is thus created for saving, which is also displaceable, so that here is a flexible adaptability of different angles of attack of the rafters is guaranteed.

According to an advantageous embodiment of the method for producing the roofing device is made after the longitudinal displacement for adjusting a roof pitch in the latched state, a positive longitudinally secured pivoting of the rafter holder relative to the side rail profile. Advantageously, in this way in the locked state, a desired angle of attack of the rafter relative to the side rail profile, in particular in a predetermined pivoting range with positive or negative employment, can be adjusted. Advantageously, despite the pivoting the longitudinal positioning remain secured.

In another embodiment, prior to inserting the bearing profile section into the encompassing section, a step of stationary mounting of the side rail profile is provided. The longitudinal displacement is made accordingly by moving the rafter holder along the side rail profile. Advantageously, only the rafter holder needs to be manipulated in this way, so that the assembly is simplified.

The above embodiments and developments can, if appropriate, combine with each other as desired. In particular, all the features of a roofing device are transferable to a method for producing the roofing device, and vice versa. Further possible refinements, developments and implementations of the invention also include combinations, not explicitly mentioned, of features of the invention described above or below with regard to the exemplary embodiments. In particular, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present invention.

The introductory section 7 may in other embodiments also with a different shape of the recess 17 be formed. The recess 17 For example, it can also be sickle-shaped. The function of the secant-like recess 17 is equal to a crescent-shaped recess. Due to its straight course, however, the secant-like recess is comparatively easier to produce, for example by means of a straight crossing of a conventional cutter with a cylindrical shape.

Furthermore, here is the bias of the locking means 8th can be seen, which in comparison to the relaxed state in 2 recognizable in the Umgreifabschnitt 6 resiliently pressed in and thus biased.

4A shows a cross-sectional view through a latching portion 15 of the side member profile 2 and the rafter holder 3 the roofing device 1 ,

The position shown here is based on the position according to 3A by longitudinal displacement of the rafter holder 3 ingested. The rafter holder 3 is here accordingly along the bearing profile section 4 from the insertion section 7 to the resting section 15 displaced longitudinally.

As can be seen in this view, encompasses the Umgreifabschnitt 6 now the bearing profile section 4 in an angular range greater than 180 °, so that there is a positive connection. In addition, due to the round shape of the bearing profile section 4 and the recess 8th of the Umgreifabschnitts 6 a pivoting of the rafter holder 3 relative to the side member profile 2 allows. In this position is the Umgreifabschnitt 6 the rafter owner 3 thus positively locking and pivoting with the bearing section section 4 of the side member profile 2 connected.

In addition, in this position, the locking and counter-locking means 8th . 9 engaged with each other.

4B shows a detailed view of the roofing device 1 according to 4A in the area of the Umgreifabschnitts.

The locking means 8th is with one in the Umgreifabschnitt 6 arranged resilient pressure piece 12 and the counter-ratchet 9 with one on the bearing profile section 4 introduced circumferential groove 13 educated. In the longitudinal sliding slides in accordance with 3A and 3B into the Umgreifabschnitt 6 indented pressure piece along the surface of the bearing profile section 4 and snaps when reaching the circumferential groove 13 by its spring bias in the circumferential groove 13 on. The circumferential groove 13 thus limits the longitudinal displacement, so that a longitudinal securing of the rafter holder 3 is reached.

The rafter holder 3 is relative to the side rail profile 2 while maintaining the positive connection in a swivel range of an angle 10 pivotable about the longitudinal axis of the bearing profile section in different angles of attack. This is achieved by the bearing profile section 4 formed umgreifbar in a larger circumferential angle than the Umgreifabschnitt 6 the bearing profile section 4 embraces.

For example, here is a circumferential angle, in which the bearing profile section 4 can be moved around, more than 270 °. Further, there is a circumferential angle in which the Umgreifabschnitt 6 the bearing profile section 4 encompasses, at more than 180 °. This results in a theoretical swivel range, which results in absolute terms from the difference between these circumferential angles and can be 60 ° by way of example. In fact, limit transition radii and / or other sections of the side rail profile 2 and the rafter owner 3 the swivel range, so that a usable swivel range is lower. About this usable pivoting range then extends the counter-locking means 9 forming circumferential groove 13 ,

The Umgreifabschnitt 6 is in a latched state, therefore, a predetermined with the circumferential groove rotation angle 10 around the longitudinal axis of the bearing profile section 4 pivotable. In the illustrated embodiment, the angle is 10 exemplary 27 °. In other embodiments, of course, differently sized pivoting ranges are possible. For example, the angle 10 in the range of 10 ° to 45 °, preferably in the range of 15 ° to 35 °, particularly preferably in the range of 25 ° to 30 °.

Thus, in a locked state diverse positions of the rafter holder 3 relative to the side rail profile 2 by pivoting the rafter holder 3 taking. In the illustrated exemplary embodiment, the range is a possible angular position 11 the rafter owner 3 to the side rail profile 4 in a locked state between 3 ° and 30 °. In other embodiments, however, are of course other sized areas of a possible angular position 11 possible, for example, from 0 ° to 45 °. Theoretically, negative areas are also the angular position 11 conceivable.

5A shows a cross-sectional view of the roofing device 1 according to 4A in a horizontal state.

A position of the rafter holder 3 and chafing 5 relative to the side rail profile 2 is accordingly 0 °. As a rule, at least a small angle of inclination is provided in an installed roofing device in order to ensure the expiry of precipitation, this is a relevant only for the assembly or disassembly position.

According to the invention, such a position can be taken to the longitudinal securing of Umgreifabschnitts 6 the rafter owner 3 on the bearing profile section 4 of the side member profile 2 to solve. The latching and counter-locking means 8th . 9 are thus by exceeding the predetermined rotation angle 10 or the predetermined angle section 11 detachably formed.

In the illustrated embodiment, the rafter holder is adjusted to the illustrated horizontal position out in a negative angle. The latching and counter-latching means 8th . 9 are designed and designed so that the engagement dissolves. Accordingly, there is no longer longitudinal security and the rafter holder 3 can go back to the introductory section 7 longitudinally displaced and removed there. Thus, the roofing device can not only be mounted in a simple manner, but also be easily disassembled tool-free again.

5B shows an enlarged view of the roofing device 1 according to 5A in the area of latching and counter-locking means 8th . 9 ,

In this illustration, it can be seen that the circumferential groove 13 at its upper end with a slope 14 expires. This allows the latching connection of the latching and counter-locking means 8th . 9 solve by the pressure piece 12 by exceeding the horizontal position along the slope 14 back into the Umgreifabschnitt 6 is pushed in and in this way. from the circumferential groove 13 is pressed out. At the end of the slope 14 is the pressure piece 12 thus again on the outer surface of the bearing profile section 4 on and can accordingly with longitudinal displacement of the rafter holder 3 again in the longitudinal direction along the bearing profile section 4 slide.

Furthermore, the pressure piece 12 formed in the illustrated embodiment with a rounded head. It can thus already in the illustrated horizontal or 0 ° position, in which it already largely from the circumferential groove 13 is pushed out, by the rounded shape with some effort, such as a rubber mallet, directly in the longitudinal direction of the bearing section profile 4 now be squeezed out.

Between the rafters 5 runs a infill 24 , which is exemplified as a glass infill. Alternatively or additionally, however, can also be a infill 24 be provided in the form of different types of plates, such as so-called double-skin sheets or opaque plates.

On one of the side rail profile 2 opposite end of the rafters 5 These are about a pivot bearing on a parallel to the side member profile 2 running purlin 19 stored. An angle of attack of the rafters 5 is relative to the wall 20 or of the wall connection profile fixed thereto 2 positively, so that the roofing device 1 from the side rail profile 2 out to the purlin 19 falls off. The purlin 19 thus here forms a Fußpfette.

The purlin 19 comes from two posts attached at the end 21 supported, which in a soil 22 are anchored.

On the side rail profile 2 opposite end of the rafters 5 is also a cross to the rafters 5 or parallel to the purlin 19 running gutter 23 provided with associated drain pipe for receiving and discharging precipitation.

According to the invention, such a patio roofing without measuring the infill 24 in terms of the distance of the rafters 5 assemble. Instead, the rafter owners 3 with the factory pre-assembled locking devices 8th at the factory prefabricated insertion sections 7 introduced along the bearing profile section 4 longitudinally displaced and at the factory also prefabricated locking sections 15 with counter-locking devices 9 brought into engagement and so longitudinally secured. The distance of the individual rafters 5 provided latching sections 15 and the dimensions of the infills 24 are prefabricated in such a way that already factory-dimensioned expansion joints 29 for infill 24 are predetermined. Accordingly, the measure of all infills fits directly 24 for positioning the latched rafter holders 3 , In particular, a last used infill needs 24 not to be adjusted in terms of their measurement.

In addition, the terrace roofing with the in the DE 20 2016 005 196 U1 constructed further described in detail further elements.
