Description

FIELD OF THE INVENTION

The present invention relates to a canopy device.

TECHNICAL BACKGROUND

Canopies are used for a wide variety of applications. A frequently encountered type of roofing is the so-called terrace roofing.

Although the present invention and the problems on which it is based are described below on the basis of a terrace roofing, they are not limited to this but can be transferred to various types of roofing.

Terrace roofing often has a side member profile designed as a wall connection profile, which is anchored to a wall with fastening means, for example bolts. Due to structural or local conditions, an installation height of such a wall connection profile can vary. On a side facing away from the wall, the terrace covering is usually stored with a purlin supported by posts. All of these components are usually prefabricated parts that are pre-produced in standard sizes. It is therefore desirable to be able to vary an angle of attack of the rafters during assembly, which results from the assembly height of the wall connection profile and the height of the posts, in order to be able to react in a simple manner 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 that is provided with a wall connection. For this purpose, wall connection fittings are provided on a wall connection profile, which have a circular cylindrical recess. A rafter holder has a rafter holder fitting corresponding thereto, which has a circular cylinder which can be received in the recess. Furthermore, the rafter holder fitting has a locking flange. In this way, the rafter holder fitting can be attached and detached from the wall connection fitting in a horizontal position. If the rafter holder fitting is pivoted into an angular position, the locking flange engages under the wall connection fitting, so that the rafter holder is secured in it. A roof panel rests on the rafters here. For sealing purposes, a separate web is provided on the wall connection profile, on which a seal that is applied to the roof panel is provided.

The disadvantage of mounting with such a system is that the angle of the rafters is not completely free to choose, since a minimum inclination is necessary in order to ensure securing by the closure flange. Furthermore, the web or the seal for sealing the roof panel must be designed for the desired angle of attack or adapted to it during assembly.

The applicant has one in the DE 20 2016 005 197 U1 The solution described has been found which provides a rafter holder for holding a rafter on a longitudinal beam profile and a receiving profile which can be locked on the rafter holder and which is designed to receive a infill in a region adjoining the rafter holder along the longitudinal beam profile.

When terrace roofing is installed, individual profile parts are often sealed with silicon or comparable sealing compounds. However, these are often not permanently weather-resistant or can tear as a result of thermal expansion or frost, causing it to unwanted water entry. This can result in long-term damage, for example due to frost blasting or corrosion.

SUMMARY OF THE INVENTION

Against this background, the present invention is based on the object of specifying an improved roofing device.

According to the invention, this object is achieved by a roofing device with the features of patent claim 1.

Accordingly, a roofing device, in particular for terrace roofing, is provided, comprising: a rafter holder for holding a rafter on a side member profile; and a receiving profile which is designed to receive a infill in an area adjoining the rafter holder and can be locked on the rafter holder; a fastening strip which can be locked on the receiving profile and is designed for fastening the infill received on the receiving profile; and a rafter, which is mounted on the rafter holder, the rafter having a drainage channel arranged in the assembled state below the infill, with a first sealing plane formed with a first seal to the receiving profile being provided on the fastening strip above the infill, which is in the rafter holder passes, and wherein the rafter holder has a first transition from the first sealing plane to the drainage channel.

The knowledge on which the present invention is based is that, in addition to an external sealing of profile parts of a roofing device due to the creeping behavior of water, it is also advantageous to remove water which penetrates despite the sealing, for example in the event of driving rain, in order to enable silicone-free assembly. Another finding is that water reaching a sealing plane primarily moves along the seal or along edges formed in the seal joint.

The idea on which the present invention is based is to provide a sealing plane between the fastening strip and the receiving profile on a fastening strip for fastening a infill accommodated on the receiving profile and to carry it into the rafter holder adjoining the receiving profile in order to prevent any water entering the sealing plane by means of a transfer of the rafter holder through the rafter holder into a drainage channel of the rafter.

The sealing plane is preferably provided continuously along the fastening strip. Accordingly, the fastening strip preferably extends in the longitudinal direction over the receiving profile up to the rafter holder. The seal is preferably received in the rafter holder in such a way that water moving along the seal is discharged via the conduit into the drainage channel.

This advantageously results in a significantly simplified assembly according to the invention, since no silicone seal is required in the joint area between the mounting profile, fastening strip and rafters. The silicone-free installation is made possible by targeted drainage from the sealing level via the rafter holder, which effectively drains away unwanted water in the area of the mounting profile. A completely impenetrable seal, as is generally to be achieved with silicone seals, is therefore no longer necessary according to the invention. Instead, penetrating emergency water or residual water can be drained off in exceptional cases.

According to the invention, the discharge is realized by means of a transfer of the rafter holder. The transition ensures the predetermined transition of the water from the sealing plane above the infill into the rafters' drainage channel below the infill.

For the purposes of the present application, a transition is therefore in particular not a simple intersection between a rafter and a fastening strip to understand. Rather, it is a transfer from the sealing level to the rafters holder interposed in the drainage path into the rafters' drainage channel.

Thus, according to the invention, a functional integration is created in the rafter holder, which in addition to its primary mechanical function of holding a rafter on a side member profile also plays an important role in water management.

In this way, long-term tightness of the roofing device is advantageously ensured, in particular because external seals are not the only thing that matters, but in the case of penetrating water, it is discharged via a predetermined drainage path through the rafter holder into a drainage channel.

The rafter holder can be received on a side member profile, which is designed for the rotatable mounting of a rafter holder. The longitudinal beam profile can have different configurations, for example it can be designed as a wall connection profile or as a purlin.

The receiving profile, which serves as a rear wall in the area between two rafters, can in particular additionally be supported on the longitudinal beam profile for locking on the rafters. The receiving profile is thus arranged along the longitudinal beam profile in an area adjoining the rafter holder. According to the invention, flexible adjustment of the setting angle of the rafter holder together with the receiving profile is made possible relative to the longitudinal beam profile. The function of the sealing level remains guaranteed. For this purpose, the receiving profile can slide, for example, on the side member profile and thus, together with the fastening strip and the seal, can also be pivoted in the same way as the rafter holder when the angle of attack changes.

The canopy device according to the invention can thus be implemented in a wide variety of configurations without doing anything to that Sealing and discharge concept, especially on the seals themselves, must be adapted.

A rafter holder is a body that is suitably designed to hold a rafter on a side member profile, which has a fastening side for attaching a rafter, a bearing side for mounting on a side member profile and means for transferring from a sealing plane located above a infill to a drainage channel below the infill .

A recording profile is to be understood as a profile suitable for recording a infill. In particular, such a mounting profile is arranged in the area between two adjacent rafter holders.

The first sealing plane is formed in particular between the receiving profile and the fastening strip. For example, either the mounting profile or the mounting strip can accommodate the seal.

A fastening strip is to be understood as a profile designed to fasten a infill to the receiving profile, which is contacted to form the first sealing plane with the first seal. Furthermore, the first seal is contacted with the receiving profile.

Advantageous refinements and developments result from the further subclaims and from the description with reference to the figures of the drawing.

According to one embodiment, the fastening strip above the infill and below the first sealing plane has a second sealing plane, formed with a second seal, for the receiving profile, which also merges into the rafter holder. The rafter holder has a second transition from the second sealing level to the drainage channel. In particular, the first sealing plane extends further in the rafter holder than the second sealing plane. Accordingly, the first seal is preferably received in a region of the rafter holder that is closer to the rafter than the second seal, which is received in a region of the rafter holder that is arranged below the first seal and preferably further out. In this way, the tightness of the roofing device is advantageously ensured even when the first sealing plane is overcome. Redundancy is thus created, which allows additional security against moisture penetration and thus, in particular, silicone-free assembly. The second transfer is preferably a transfer that is at least partially separate from the first transfer. Furthermore, the second seal is preferably a seal that is spatially separate from the first seal. The second sealing plane is preferably also provided between the fastening strip and the receiving profile.

According to one embodiment, the fastening strip for locking on the receiving profile has a first support web which, together with the first seal, forms the first sealing plane. The fastening strip also has a second support web which, together with the second seal, forms the second sealing plane. With the two support webs, the fastening strip can advantageously apply a pretension supported on the receiving profile to the infill. This is made possible, in particular, despite tool-free assembly, since a lever effect can be used to apply the pretension with two support webs.

According to one embodiment, a first locking section and a second locking section are provided on the mounting profile, on which the first and the second support web can be locked with the mounting profile for locking. In this way, a tool-free assembly of the fastening strip is made possible by applying a pretensioning force to the infill.

According to a further development, the first seal is arranged in the first locking section and the second seal in the second locking section. When the fastening strip is locked, the first support section thus arrives in contact with the first seal and the second support section with the second seal. The respective sealing plane is thus advantageously formed in a simple manner directly when the fastening strip is locked on the receiving profile.

According to an advantageous development, the locking sections and the seals are provided continuously on the receiving profile. The first support web which is latched against the first seal on the first locking section thus continuously forms the first sealing plane, which represents an outer or primary sealing plane. The second support web, which is snapped onto the second locking section against the second seal, forms the second sealing plane, which is also above the infill. Any water that overcomes the first sealing level and penetrates into the fastening strip can thus be caught on the second sealing level and discharged via the rafter holder.

According to a preferred embodiment, the first and the second support web together form a channel, along which water penetrating the first sealing level can additionally be discharged into the drainage channel. In particular at high angles of attack, for example in the range> 20 °, in particular> 30 °, water reaching the second density level can also flow into the fastening strip instead of along the second seal. By means of the channel, water which penetrates in this way is advantageously kept away from points which are susceptible to passage behind the receiving profile, in particular in the joint region between the rafter holder and the receiving profile.

In an advantageous further development, the second support web is arranged below the first support web and is inclined relative to the receiving profile. Penetrating water is thus led along the inclined surface of the second support web away from the receiving profile into the channel.

According to one embodiment, there is a sealing cushion bridging the butt region in a butt region between the rafter holder and the receiving profile inserted in the mounting strip, which has a locally delimiting recess. On the one hand, the sealing cushion forms a seal in the gap between the rafter holder and the receiving profile and, on the other hand, holds any water in the channel in an area of the fastening strip which is remote from the receiving profile. In this way, the channel is tapered to a narrow cross-section in the area of a transition between the fastening strip and the rafter holder. A targeted drainage of the water into the drainage channel of the rafters is thus advantageously ensured. Furthermore, a gap between the fastening strip and the rafter holder is advantageously bridged in this way. This effectively prevents water from seeping into the gap area between the two sealing levels, even if the gap should open due to thermal expansion effects or other distortion.

The fastening strip also preferably extends in the longitudinal direction beyond the receiving profile up to the rafters. The sealing levels therefore do not need to be penetrated in order to drain water that has penetrated into the channel. Instead, water that has penetrated can be fed directly into the rafter's drainage channel via the gutter via the gutter.

According to one embodiment, the first and / or second transition is integrally formed in the material of the rafter holder. For example, suitable guide elements can be milled into the material of the rafter holder. No additional components are therefore advantageously necessary.

According to one embodiment, the rafters are formed with a rafters profile in which the drainage channel is integrally formed. The shape of the rafter profile corresponds to the shape of an attachment side on which the rafter profile is attached to the rafter holder. This enables a direct transfer of the water from the channel into the drainage channel. For this purpose, the rafter holder preferably has a suitable guide which specifically guides the water from the channel to the drainage channel.

According to an advantageous development, in addition to the drainage channel, an emergency water channel of the rafters running parallel thereto is provided. The emergency water channel can be arranged, for example, below a support seal provided for receiving the infill. The rafter holder has an overflow from the drainage channel to the emergency water channel. In this way, the water is primarily supplied in the drainage channel within the rafters and, if this is fully utilized in terms of its absorption capacity, is additionally discharged via the emergency water channel. In this way, on the one hand, the profile cross section of the rafters is optimally used. In addition, an additional function as an emergency water channel is thus often provided below a support seal for a infill, in particular a glass support seal, to accommodate the groove provided in any case. This is also a function integration.

According to an advantageous embodiment, the rafter holder is mounted on a longitudinal beam profile and has a first surface and a second surface for locking the receiving profile, the first surface being arranged in an area above the first sealing plane and the second surface in an area below the infill. In this way, the receiving profile can advantageously be locked only by pushing it into the rafter holder, in particular between two adjacent rafter holders. The receiving profile can be introduced, for example, in an area adjacent to the rafter holder along the longitudinal member profile into an intermediate space provided between the bearing profile section and the first and second surfaces and can be locked between the longitudinal member profile and the rafter holder by being supported on the longitudinal member profile, the first surface and the second surface. The insertion and locking is in particular only provided in a lateral area of the receiving profile, since in particular the first and second surfaces of the rafter holder are provided there. The receiving profile is preferably equally inserted and locked on two adjacent rafter holders. The receiving profile is supported on the side member profile in particular over its entire length.

According to an advantageous development, the first surface is provided with a seal, at least in the joint area between the rafter holder and the receiving profile. In this way, a mechanical locking of the receiving profile on the rafter holder is created, which is sealed in the joint area. This also prevents water from seeping into the gap area.

The receiving profile preferably has approximately the same height as the rafter holder, so that it is supported on its upper and lower side by the first and second surfaces. In the assembled state, the first and the second surface are preferably provided or arranged oriented to the side member profile. The receiving profile is supported on the side member profile, preferably in a central region. In this way, the receiving profile is advantageously supported both in the upper area and in the lower area.

The side member profile preferably has, at least in sections, a rounded surface on which the side of the receiving profile facing the side member profile can slide and can thus be aligned with the rafter holder at different angles of incidence to the side member profile. In this way, an infill, for example a glass infill, is always stored in the roof inclination predetermined by the angle of attack of the rafter holder on the side member profile, without additional adjustments or alignment work being necessary.

According to one embodiment, the longitudinal beam profile has a cover projection extending above the rafter holder on an upper side. The covering projection at least predominantly covers the area of the rafter holder from above. An upper side of the side member profile is to be understood as a side oriented skyward in the assembled state. The cover projection has the great advantage that the entire mechanics of the rafter holder can be protected against moisture and weather influences in this way. In addition, a seal is provided between the rafter holder or the mounting profile the cover projection is arranged. In this way, protection against invading insects and the like is also ensured.

According to one embodiment, the receiving profile can be inserted from bottom to top between the bearing profile section and the first surface. In particular, it can be inserted obliquely from bottom to top. By pushing the receiving profile at least partially into the space, which is located in particular under a cover projection of the side member profile. The receiving profile can then be moved from top to bottom between the bearing profile section and the second surface such that the receiving profile is supported on one side by the bearing profile section and on the other side by the first and second surfaces. In this way, the receiving profile is completely absorbed and locked in the space. A simple, in particular tool-free, and quick assembly of the mounting profile is thus advantageously made possible. This is particularly advantageously possible despite a cover projection at the upper end of the longitudinal beam profile that is firmly connected to the longitudinal beam profile.

According to one embodiment, the first and second surfaces run parallel to one another. Accordingly, the receiving profile can be pivoted obliquely from bottom to top after insertion and from top to bottom before being moved into an orientation parallel to the first and second surfaces. By moving after pivoting, the receiving profile is then supported on the second surface, so that the locking is achieved. The shifting takes place in particular only in a direction that corresponds to the alignment of the first and second surfaces.

According to one embodiment, the first surface is designed as a plane and the second surface as a leg of a receiving angle. Another leg of the mounting bracket is designed for lower support of the mounting profile. The receiving profile is thus advantageously supported downwards in the receiving angle after locking. This is in particular for load support for the infill stored in the receiving profile, especially also for support of snow loads and the like, advantageous. In this way, a high load capacity of the roofing device can be guaranteed.

According to one embodiment, the longitudinal beam profile has a bearing profile section, on which a gripping section of the rafter holder can be positively supported. Furthermore, the receiving profile is supported laterally on the bearing profile section in a locked state. The first and second surfaces are each arranged in the longitudinal direction next to the encompassing section. In this way, the encompassing section and the receiving profile are arranged next to one another along the longitudinal beam profile in the assembled state.

A gripping section is to be understood as a section of the rafter holder which is suitable for gripping around the bearing profile section. When reaching around, 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, articulated coupling of the rafter holder to the longitudinal beam profile.

According to one embodiment, the receiving profile has a support lug designed to be supported on the bearing profile section. In particular, the support lug is designed at least in sections to correspond to the bearing profile section. Preferably, both the bearing profile section on a section on which the support lug is supported and the support lug are rounded, at least in sections, so that they can slide against one another, in particular in a rotational manner. In this way, easy adjustment of different angles of attack of the receiving profile is made possible together with the rafter holder.

According to one embodiment, the support nose seals off the space provided between the bearing profile section and the first surface. In particular, it insect-tightly closes the interspace. This effectively prevents insects from entering. For example, the nesting of flight-building insects such as wasps, hornets or the like is prevented in this way.

According to one embodiment, the receiving profile has a supporting surface provided for support on the first surface and a locking surface provided for locking the receiving profile by supporting on the second surface. The support surface is preferably designed to correspond to the first surface and designed to be displaceable along the first surface. The locking surface is in particular provided such that it can be brought into engagement with the second surface by moving the receiving profile along the first surface.

According to one embodiment, the receiving profile is designed as a glass receiving profile for receiving a glass infill. It has a glass sealing section which protrudes upwards in front of the second surface in a locked state. In this way, a glass infill along the longitudinal beam profile rests only on the glass sealing section of the receiving profile, so that damage-free and sealed storage is advantageously made possible.

According to one embodiment, the rafter holder and the receiving profile have a seal receptacle at their upper end, which in the locked state are aligned to receive a lower end of a continuous seal. In particular, the inclusion of a dirt and insect protection seal mounted with its upper end on the cover projection is made possible in the seal receptacle. Effective protection from invading insects, in particular nest-building flying insects such as wasps or hornets, is thus advantageously made possible in a simple manner. Furthermore, the dirt and insect protection seal also serves to protect against dirt, for example leaves, cobwebs or the like, which accumulates in the cavity or intermediate space. In addition, it can also serve to displace moisture.

For assembly, insertion into the intermediate space and locking of the receiving profile is preferably carried out by pushing it from bottom to top between the bearing profile section and the first surface and subsequent displacement made of the receiving profile from top to bottom between the bearing profile section and the second surface. This is preferably done in such a way that the receiving profile is supported on one side by the bearing profile section and on the other side by the first and second surfaces. The mounting profile is preferably inserted by slanting it from bottom to top. In this way, the receiving profile can be inserted and locked in a simple manner between the bearing profile section and the rafter holder, without the need for tools. According to a preferred development, the first and second surfaces run parallel to one another. After insertion obliquely from bottom to top and before shifting from top to bottom, the receiving profile is therefore pivoted into an orientation parallel to the first and second surfaces. In this way, it can advantageously be moved along the first and second surfaces into the locked position.

The above refinements and developments can, if appropriate, be combined with one another as desired. Further possible refinements, developments and implementations of the invention also include combinations of features of the invention described above or below with reference to the exemplary embodiments, which are not explicitly mentioned. 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.

DESCRIPTION OF EMBODIMENTS

Fig. 1 shows a perspective sectional view of a roofing device.

The roofing device 1 is designed here with a glass infill. A joint area is shown between a receiving profile 4 receiving the infill 7 in the longitudinal direction and a rafter 5 receiving the infill 7 in the transverse direction.

A rafter holder 3 is provided in the joint area shown, but is largely covered in the illustration shown.

The rafter 5 is fastened to the rafter holder 3. The rafters holder 5 is used to hold the rafters 5 on a longitudinal beam profile 2, not shown here, for example in the case of a terrace covering, a wall connection profile. Furthermore, the receiving profile 4 is received on the rafter holder 3. By additional support on a side member profile, the receiving profile 4 can be locked on the rafter holder 3.

In the illustrated embodiment, the receiving profile 4 is suspended on the side of the rafter holder. Of course, other types of locking, for example screwing, locking or the like, are also possible.

The receiving profile 4 extends over a region adjoining the rafter holder 3 in the longitudinal direction. There is a joint area 49 or a gap at the transition between the rafter holder 3 and the receiving profile 4. According to the invention, this gap, which is susceptible to water ingress, is also provided free of silicone during assembly.

A fastening strip 6, which can be locked on the receiving profile 4, is provided for fastening a infill 7 which can be received on the receiving profile 4. A sealing plane formed with a seal 16 is provided from the fastening strip 6 to the receiving profile 4, which is symbolized here by a thick dashed line and is also silicone-free. The sealing plane is continued over the butt region 49 or gap provided between the rafter holder 3 and the receiving profile 4 as far as into the rafter holder 3. The fastening strip 6 and the seal 16 thus extend along the fastening strip over the receiving profile 4 into the rafter holder 3.

The rafters 5 fastened to the rafter holder 3 have a drainage channel 8 below the infill 7. The drainage channel runs along the entire rafter 5 and opens, for example, into a gutter attached to the other end of the rafter 5, which is not shown here.

Although the seal 16 is arranged in a non-exposed area, water penetrates into the seal 16, particularly in the event of heavy precipitation moves along the seal into the rafter holder 3. In order to drain off the water, a transition 9 from the first sealing level to the drainage channel 8, which is covered here by an expansion sealing piece, is provided in the rafter holder 3. Since the transition 9 is covered in the view shown, it is symbolized by a dashed arrow.

The conduit 9 formed with the rafter holder 3 thus transfers penetrating water from the first sealing plane arranged above the infill 7 into the drainage channel 8 arranged below the infill 7

Fig. 2 shows a front view of a canopy device 1.

The rafter 5 shown here in a top view is formed with a rafter profile. As an example, the embodiment shown is an extruded aluminum profile. Depending on the vertical load, this can be provided with a steel core if necessary.

The rafter profile is essentially T-shaped in cross-section and has a T-arm 51 on both sides at the lower end to accommodate the infill 7 and a central T-foot. Accordingly, in the T-arm 51 there is provided a groove, which also serves as an emergency drainage channel 18, for receiving a glass contact seal 44. Adjacent to this and facing the T-foot 52 inwards, the drainage channel 8 is integrally formed in the rafter profile.

In addition, a rafter fastening strip 50 is also provided on the rafter 5 for fastening the infill 7 to the rafter. Since this runs parallel to the drainage channel with the rafter pitch and the rafter profile is closed, no special sealing to the rafter profile is required here.

To contact the infill 7, a glass seal, not shown here, is provided on the underside of the fastening strip 50.

Fig. 3 shows a sectional view of the canopy device according to Fig. 2 along the section line AA.

In this illustration, section through the receiving profile 4 and the fastening strip 6 is shown. In addition to the first seal 16, a second seal 17 can be seen here between the receiving profile 4 of the fastening strip 6. Accordingly, the fastening strip 6 above the infill 7 and below the first sealing level has a second sealing level formed with the second seal 17 to the receiving profile 4.

In this illustration, the locking of the receiving profile 4 on the lateral edge of the rafter holder 3, through which the cutting plane A-A also extends, can also be seen. The receiving profile 4 is suspended on the side of the rafter holder 3, which has a first surface 38 on the upper side and a hook-like section on the underside with a second surface 39 for supporting the receiving profile 4. In the final assembled state, the receiving profile 4 can be supported on the back on a longitudinal beam profile, not shown here, on which the rafter holder 3 is also mounted.

Fig. 4 shows a front view of a receiving profile 4 inserted into a rafter holder 3.

The first and second sealing planes formed with the first and second seals 16, 17 are shown schematically by dashed thick lines. The first sealing plane formed with the first seal 16 extends further into the center of the rafter holder 3 than the second sealing plane formed with the second seal 17. In this way, quantities of water derived from the first and second sealing planes advantageously meet one another only in the drainage channel 8. The transition from the respective density levels does not influence each other, but is provided independently.

Furthermore, a sealing pad 21 is arranged in a joint region 49 between the rafter holder 3 and the receiving profile 4 between the first sealing plane of the second sealing plane. In particular, this prevents moisture from penetrating backwards between the two sealing planes through the gap present in the joint region 49, which can widen, for example, through thermal expansion effects.

In a lower area of the rafter holder, the conduits 9, 10 pass into the drainage channel 8, which already begins in the rafter holder 3.

Fig. 5 shows a schematic representation of the drainage paths through the rafter holder 3.

The rafter holder 3 is shown here in perspective together with the first and second seals 16, 17, which are designed as a sealing cord, for example.

The first seal 16 is received in a first seal receptacle 53 of the rafter holder 3 and is guided up to a rafter receptacle 30. The seal receptacle 53 ends at the same height as the drainage channel 8. The first conduit 9 extends from the seal receptacle 53 vertically downward to the drainage channel 8. The first drainage path thus runs from the first seal 16 along the first conduit 9 straight down into the Drainage canal.

The second seal 17 extends to a guide element 19 arranged between the first transfer line 9 and a second transfer line 10. From the guide element 19 to the edge of the rafter holder 3, a second seal receptacle 54 is provided in the rafter holder 3. A second conduit 10 extends obliquely downward from the second seal receptacle 54 to the drainage channel 8. The second drainage path thus runs obliquely downward from the second seal 17 along the second conduit 10 into the drainage channel 8.

In addition, a rafter holder is provided with a recess 33 for receiving an electrical connector (not shown here) for any electrical lines routed in the rafter. This is separated from the entire water supply, in particular from the drainage channel 8.

Fig. 6 shows a detailed representation of the leads 9, 10 of the rafter holder.

These are crossovers 9, 10 formed integrally in the material of the rafter holder 3.

The rafter holder is designed, for example, as an injection-molded part or a die-cast part, so that the seal receptacles 53, 54, the conduits 9, 10 and a start of the drainage channel 8 and the emergency water channel 18 are realized therein with a suitable milling.

The emergency water channel 18 is provided in addition to the drainage channel 8 running parallel to it in the rafter profile of the rafter 5. To feed the emergency water channel, which runs separately from the drainage channel 8 in the rafter profile, an overflow 20 from the drainage channel 8 to the emergency water channel 18 is provided in the rafter holder 3, that is to say at the beginning of the drainage channel 8. If the drainage channel 8 is therefore utilized to the extent that a water level rises above the overflow 20, the water passes into the emergency water channel 18, as shown schematically with the curved case. In this way, the emergency water channel 18 can also be used for drainage when the water volume is very high.

Fig. 7 shows a sectional view of a receiving profile 4 with an attached fastening strip 6.

The contour of the fastening strip 6 can be seen in detail from this view. This has a first support web 11 for locking on the receiving profile 4, which together with the first seal 16 forms the first sealing plane to the receiving profile 4. The fastening strip also has a second support web 12 which, together with the second seal 17, forms the second sealing plane with the receiving profile 4.

Furthermore, the fastening strip 6 has a fastening web 13, to which a glass seal (not shown here) can be attached, which contacts the infill 7 in the assembled state.

A first locking section 14 and a second locking section 15 are provided on the mounting profile 4. These are each designed as locking sections, on which the first and the second support web 11, 12 can be locked with the receiving profile 4 for locking. The support webs 11, 12 have corresponding locking sections corresponding to the locking sections 14, 15, which here are formed with webs and undercuts integrated in the profile of the fastening strip.

The first seal 16 is arranged in the first locking section 14 and the second seal 17 in the second locking section 15 on the receiving profile 4. For this purpose, the receiving profile 4 has a sealing receiving groove in the area of a locking section 14, 15, which is dimensioned such that the supporting webs 11, 12 are in contact with the respective seal 16, 17 in the locked state, so as to close the first and second sealing planes form.

In the assembled state, the seal receiving grooves of the receiving profile 4 are also at the same height as the seal receptacles 53, 54 provided in the rafter holder 3, so that the seals 16, 17 are guided into the rafter holder 3 just across the gap in the joint area 49.

The locking sections 14, 15 and the seals 16, 17 are provided continuously on the receiving profile 4 in the manner shown here in cross section. The fastening strip 6 and the seals 16, 17, however, extend beyond the receiving profile 4 into the rafter holder 3.

As can be seen in the view shown, the first and the second support web 11, 12 further jointly form a channel 23 which is removed from the receiving profile 4. In the embodiment shown, the second support web 12 is designed to be sloping or sloping, so that in the joint between the first and second support web 11, 12 forms a wedge-shaped groove 23.

Along the trough 23, any water penetrating the first sealing plane, which can also detach from the second seal 17 or move away in the direction of the trough, for example in the case of very strong water or in the case of a high angle of attack of the rafters, for example of 30 ° be discharged into the drainage channel 8. In this way, penetrating water is always kept away from the point in the joint area 49 between rafter holder 3 and the receiving profile 4 which is susceptible to a passage behind the receiving profile.

Fig. 8 shows a perspective view of a sealing pad 21 that can be inserted into the fastening strip 6.

The sealing pad 21 essentially has the shape of the cavity formed between the fastening strip 6 and the receiving profile 4. Deviating from this, a recess 22 is provided only in the region of the channel, which allows water in the channel to pass into the rafters 5.

Fig. 9 shows a perspective view of the receiving profile Fig. 7 in a locked state on the rafter holder.

In this view it can be seen that the fastening strip 6 extends in the longitudinal direction beyond the receiving profile 4 into the rafter holder 3. In the assembled state, the fastening profile 6 is guided up to the rafter profile with a small gap sufficient for transferring the water from the channel 23. The sealing pad 21 is inserted in the joint area 49 between the rafter holder 3 and the receiving profile 4 in the fastening strip 6 and thus bridges the joint area 49 between the two sealing planes.

The groove 22 is delimited locally with the recess 22, so that the groove 23 opens directly into the rafters 5 fastened to the rafter holder 3 and escaping water reaches the drainage channel.

Fig. 10 shows a perspective view of the canopy device 1 with the third drainage path shown.

In order to illustrate the drainage path, the fastening strip 6 is shown broken out in the area of the rafter holder 3 here. In fact, the fastening strip in this area is, as in Fig. 9 shown, continued completely up to the rafters 5.

Water emerging from the channel 23 reaches the rafters profile down into the drainage channel 8, as symbolized by the thick arrows. It is therefore a third drainage path which is independent of the first and second conduits 9, 10, but which only comes into play in the event of extreme water ingress or in the case of very steep roof slopes, for example> 20 °.

In the case of usual amounts of water and roof pitches, however, entering water moves predominantly along the first and second seals 16, 17 and is discharged into the drainage channel 8 through the leads 9, 10 of the rafter holder 3.

The entire sealing concept of the illustrated embodiment can thus be summarized as follows:
The first sealing plane formed with the first seal 16 prevents water from penetrating behind the fastening strip. Instead, the water gets through the first transfer 9 of the rafter holder 3 is discharged. Should, however, for example during heavy rain, water possibly penetrate the first sealing level and penetrate behind the fastening strip, the second sealing level formed with the second seal 17 prevents the water from accumulating in the lower part of the receiving profile 4. Instead, the water which has penetrated becomes along the second sealing level passed into the rafter holder and discharged by means of the second transfer 10.

If the water partially detaches from the second sealing level, which would only be expected in the case of large amounts of water penetrating, for example as a result of a defect, or in the case of a very steep angle of attack of the roofing, for example at 30 °, the channel 23 enables drainage via the third Drainage path. For this purpose, the sealing pad 21 inserted into the fastening strip 6 in the joint region 49 enables, with its recess 22, an additional drainage of the water in the region of the fastening strip 6 facing away from the receiving profile 4 and at the same time prevents infiltration in the joint region 49.

Fig. 11 shows a perspective view of a longitudinal beam profile 2 and a rafter 5 to be mounted thereon.

The roofing device 1 has a longitudinal beam profile 2, which is designed here, for example, as a wall connection profile, on which the rafter holder 3 formed on its bearing side 32 for holding or mounting the rafters 5 on the longitudinal beam profile 2 can be received. The rafter 5 is fastened to the fastening side 31 of the rafter holder 3.

The longitudinal beam profile 2 has a bearing profile section 24 designed for mounting the rafter holder 3. The bearing profile section 24 is formed with a sectionally round shape, here for example a hollow circular cylinder shape, which is integrally connected to a wall connection area of the wall connection profile.

The longitudinal beam profile 2 is designed, for example, as an extruded profile. In particular, it contains aluminum. Other extrudable materials, for example plastics, would alternatively or additionally also be conceivable.

The longitudinal beam profile 2 has, for example, two insertion sections 28, which are provided on both sides next to a latching section 25 provided with a latching means 29. In these insertion sections 28, the bearing profile section 4 is locally excluded, here, for example, with a secant-like recess 27. The mounting of the rafter holder 3 on the side member profile 2 is thus possible on both sides of the latching section 25. Of course, a single or one-sided insertion section 28 would also suffice for the function of the insertion.

After insertion, the rafter holder 3 can be positively fastened to the bearing profile section 24 by lateral displacement or longitudinal displacement into the latching section.

If the rafter holder 3 is fastened to the longitudinal beam profile 2 with the rafter 5, the receiving profile 4 can be locked to the rafter holder 3 in a region adjoining the rafter holder 3 on the longitudinal side.

Furthermore, the rafter holder and the longitudinal beam profile have a seal receptacle 48, 55, to which a connection seal 36 bridging the gap between rafter holder 3 and longitudinal beam profile 2 can be attached.

Fig. 12 shows a perspective view of the bearing side 32 of the rafter holder 3 and the receiving profile 4.

The rafter holder 3 has a gripping section 26 with a recess 27 corresponding to the bearing profile section 24. Accordingly, the illustrated embodiment is, for example, a circular cylindrical recess 27.

The gripping section 26 with its recess 27 is designed for positive mounting on the bearing profile section 24. In the assembled state, it encompasses the bearing profile section 24 to the extent that a pivotable positive connection is provided.

To lock the receiving profile 4, the first surface 38 and the second surface 39 are arranged parallel to one another, the first surface 38 being arranged in an area above the first sealing plane and the second surface 39 in an area below the infill. For mounting, the mounting profile 4 can be introduced in an area along the longitudinal beam profile 2 adjoining the rafter holder 3 into an intermediate space 40 provided between the bearing profile section 24 and the first and second surfaces 38 and by being supported on the longitudinal beam profile 2, the first surface 38 and the like second surface 39 can be locked between the longitudinal beam profile 2 and the rafter holder 3. The insertion and locking is provided in a lateral area of the receiving profile 4 adjoining the rafter holder 3, in which the first and second surfaces 38, 39 of the rafter holder 3 are arranged.

The receiving profile is preferably equally inserted and locked on two adjacent rafter holders 3. The receiving profile 4 is supported on the side member profile 2, in particular over its entire length, with a support lug 35 provided for this purpose.

In order to protect the butt regions 49 above the first sealing plane against ingress of water, the first surface 38 in the butt region 49 is provided with a seal 34 which is inserted between the first surface 38 and the receiving profile 4.

Fig. 13 shows a side view of a roofing device with connection seal 36 to the longitudinal beam profile 2.

The connection seal 36 is designed as a dirt and insect protection seal and is with its lower end in a seal receptacle 56 of the receiving profile 4 and the seal receptacle 55 of the rafter holder 3 is used. At an upper end, the connection seal 36 is inserted into a seal receptacle 48 provided on a covering projection of the longitudinal beam profile 2.

The connection seal 36 designed as a dirt and insect protection seal serves in particular to protect against the penetration of nest-building flying insects, leaves, cobwebs or the like. In addition, it also serves to displace moisture, for example in the event of extreme precipitation or when the wind is pressing under the cover projection 26, and thus supports the entire sealing concept.

The connection seal 36 is flexible, so that pivoting of the rafter holder 3 relative to the side member profile 2 is not hindered thereby.

Fig. 14 shows a perspective view of a terrace roof with wall connection.

The terrace roofing is an embodiment of the roofing device 1, in which the longitudinal beam profile 2 is designed as a wall connection profile fastened to a wall 45.

In the embodiment shown, the roofing device 1 has a plurality of parallel rafters 5, which are held on the side member profile 2 by means of rafter holders 3.

A infill 7 runs between the rafters 5, which is designed as a glass infill, for example. Alternatively or additionally, an infill 7 in the form of different types of plates, for example so-called double-wall plates or opaque plates, can also be provided. The infill 7 is received by means of the glass support seals provided on the rafters 5 and on the mounting profiles 4 arranged between the rafters holder and is fastened to the top of the infill with fastening strips 6, 50 in each case.

At an end of the rafters 5 opposite the longitudinal beam profile 2, they are supported via a pivot bearing on a purlin 46 running parallel to the longitudinal beam profile 2. An angle of attack of the rafters 5 is positive relative to the wall 45 or the wall connection profile fixed thereon, so that the roofing device 1 falls from the side member profile 2 towards the purlin 46. The purlin 46 thus forms a foot purlin here.

The purlin 46 is supported by two posts 41 attached to it at the ends, which are anchored in a floor 42.

At the end of the rafters 5 facing away from the longitudinal beam profile 2, a gutter 43 running transversely to the rafters 5 or parallel to the purlin 46 is also provided, with an associated drain pipe for receiving and removing precipitation. The drainage channels 8 of the rafters 5 open into the gutter 43.

In addition, the terrace covering is included in the DE 20 2016 005 197 U1 further elements described in detail.

Fig. 15 shows a perspective view of a terrace roof with ridge purlin.

In contrast to the embodiment according to Fig. 14 the roofing device 1 is not designed to be connected to a wall, but rather is free-standing and sloping on both sides.

The longitudinal beam profile 2 is accordingly designed here as a ridge purlin and has a bearing profile section 24 on both sides, as well as all other elements of the longitudinal beam profile 2 described in relation to the preceding figures. The longitudinal beam profile 2, designed as a ridge purlin, is articulated by means of a pivot bearing on a purlin 46 'which runs parallel to the longitudinal beam profile 2 and is supported at the end on middle posts 41'.

Purlins 46 and gutters 43 arranged as foot purlins are provided here on both sides at the end of the rafters 5 facing away from the longitudinal beam profile 2, in the same way as with reference to Fig. 15 are trained.

The drainage channels 8 of the rafters 5 open here into the respective gutter 43 on both sides.
