Description

AREA OF INVENTION

[0001] The present invention relates to a roofing device with a sealing clip for sealing a joint of longitudinal beam profiles of the roofing device, in particular for a terrace roof, and a method for sealing a joint area of ​​a first and a second longitudinal beam profile for such a roofing device. TECHNICAL BACKGROUND

[0002] The sealing of a joint between profiles is known, for example, from FR 2900219 A1 and DE 2814701 A1. A roofing device is also known from EP 3505699 A1.

[0003] Although the sealing method between longitudinal beam profiles of the roofing device according to the invention is explained in more detail below with regard to wall connection profiles, it is not limited to this but can be transferred to a wide variety of longitudinal beam profiles for roofing devices.

[0004] Roofing structures often have a width that exceeds the dimensions of a single wall connection profile. In such cases, two wall connection profiles are typically butted together. This butt joint requires a separate seal to prevent uncontrolled water ingress. Sometimes, these joints are sealed with an elastic material placed between the wall connection profiles. This material might be, for example, an elastomeric solid inserted between the longitudinal beam profiles, adapted to the profile contour, or it could be a filling or grouting with an elastic filler or sealant. However, a problem with such seals in the joint between the wall connection profiles is the high mechanical stress on the elastic material located between the longitudinal beam profiles due to thermal expansion of the profiles.The design must be such that at low temperatures, the joint in the impact area remains completely filled and sealed. Conversely, at high temperatures, the material is significantly compressed and deformed. Theoretically, temperature conditions would therefore have to be considered during installation, and a certain preload applied or maximum elongation taken into account, which is either impossible or only achievable with considerable effort in practice. Furthermore, the seal is subject to stresses from weather conditions, UV radiation, and the like. Particularly due to the natural aging of elastomeric materials, such seals can lose their sealing properties over the years. As a result, water may penetrate a roof structure, or costly maintenance work may become necessary, as replacing the seal requires dismantling the entire roof structure. SUMMARY OF THE INVENTION

[0005] Against this background, the present invention aims to provide an easily installed seal for longitudinal beam profiles in a roofing device, which has a long service life.

[0006] According to the invention, this problem is solved by a roofing device with the features of claim 1 and / or by a method with the features of claim 11.

[0007] The insight underlying the present invention is that a seal between the longitudinal beam profiles is no longer necessary if one upper surface of the longitudinal beam profiles is reliably sealed.

[0008] The underlying idea of ​​the present invention is to provide the upper surface of the longitudinal beam profiles in a joint area with a sealing clip, which can be hooked into a first profile section of the longitudinal beam profiles by a first arm and locked into a second longitudinal beam profile by a second arm. An inner surface provided on the inside of the sealing clip forms a sealing surface and is pressed onto the upper surface of the longitudinal beam profiles by the locking mechanism, so that it reliably seals the joint area.

[0009] By engaging the first arm, a positive connection is created with the upper surface of the longitudinal beam profiles, which is pre-tensioned by the engagement of the second arm, thus achieving an effective seal. According to the invention, a seal is created in this way over the entire area of ​​the joint relevant to water ingress, i.e., the surface.

[0010] The seal at the top of the longitudinal beam profiles is advantageously not subjected to thermal expansion of the longitudinal beam profiles, as it is not located between them. Furthermore, the seal is extremely easy to install without tools. In addition, the inner surface intended for sealing is covered by the web of the sealing clip and thus largely protected against weathering and UV radiation.

[0011] The invention also simplifies the assembly of a roofing device with a width exceeding the individual dimension of a longitudinal beam profile. Instead of laboriously inserting a seal between the end faces of two longitudinal beam profiles at the joint, the longitudinal beam profiles can be easily joined directly to one another, for example, using guide pins. Only after joining can a seal then be created by applying the sealing clip to the top.

[0012] The upper side of the longitudinal beam profile for a roofing device is understood to be a side oriented towards the sky when mounted.

[0013] The first profile section is preferably a section of the first and / or second longitudinal beam profile whose outer contour corresponds to the mounting element of the first arm. In particular, the sealing clip is hooked over the joint onto the first and second longitudinal beam profiles in the first profile section. The shape of the first arm and the first profile section are preferably matched such that, when hooked in, the inner surface rests on a surface of the first and second longitudinal beam profiles.

[0014] The second profile section is preferably a section of the first and / or second longitudinal beam profile provided with a counter-locking element corresponding to the locking element of the second arm. The arrangement of the locking elements and counter-locking elements is particularly coordinated such that, in a locked state, the inner surface is pre-tensioned against the top surface of the first and second longitudinal beam profiles and rests against them, preferably continuously along the web.

[0015] The inner surface is provided in particular on an inner side of the web and, depending on the contour of the longitudinal beam profiles, can extend at least partially into the first and / or second arm.

[0016] Advantageous designs and further developments result from the further sub-claims as well as from the description with reference to the figures in the drawing.

[0017] According to one embodiment, an elastic material is applied to the inner surface over a wide area. In this way, the preload that can be applied by the locking device advantageously results in a wide outer seal of the area over which the inner surface extends.

[0018] According to a further embodiment, a continuous strip of the inner surface, extending from the first arm to the second arm, is covered with the elastic material. This advantageously creates a continuous seal along the inner surface. It is conceivable to also provide further areas on the inner surface, for example, areas free of elastic material, particularly free areas running parallel to the strip. These could, for example, be used as drainage channels or the like. Furthermore, it would be conceivable to additionally flood these free areas with a sealant during or after assembly.

[0019] According to an advantageous embodiment, a first, a second, and a third strip of elastic material are provided on the inner surface. The first strip runs along a first longitudinal edge of the inner surface, the second strip along an opposite second longitudinal edge of the inner surface, and the third strip runs longitudinally along the center of the inner surface. The strips are spaced apart from one another, so that areas of the inner surface free of the elastic material are also provided. These areas can be used, for example, as sealing steps, drainage channels, or the like. Furthermore, it would be conceivable to additionally flood these areas with a sealant after assembly to achieve an even more reliable seal.

[0020] According to one embodiment, the elastic material extends from the first side of the web into the first arm. This allows, on the one hand, the transition between the top and front sides of the longitudinal beam profile to be bridged. On the other hand, the elastic material can thus serve to compensate for tolerances and / or thermal expansion in a fit between the sealing clip and the longitudinal beam profile. In particular, the elastic material abuts the mounting element, creating a seamless transition.

[0021] One conceivable configuration for the first arm is a curved hook shape. In particular, it could be a tapered hook shape with an increasing curvature. In one embodiment, the elastic material extends at least partially into the curvature of the hook shape. Specifically, the elastic material could extend to the foremost point of the inner surface. Therefore, in the case of a 180° curvature of the first arm, it extends essentially half the curvature, that is, up to a curvature of approximately 90°.

[0022] According to an advantageous embodiment, the second arm has a sealing section, the elastic material extending into which it meets the sealing section. This sealing section provides a seal in an area of ​​the upper surface of the first and / or second longitudinal beam profile adjacent to the second arm. In particular, the sealing section can be designed as an inclined inner surface section. In this case, the sealing section is configured to conform to a corresponding inclined surface on the upper surface of the first and / or second longitudinal beam profile when locked into place. Advantageously, this ensures that the locking action results in continuous contact of the elastic material with the upper surface and that any tolerances are compensated for by the elastic material.

[0023] According to one embodiment, the inner surface has at least one recess in which the elastic material is received. In particular, the recess extends over at least a certain portion of the surface. For example, the recess can be a pocket, groove, or step on the inner surface. The recess can extend over only a portion of the inner surface or over the entire inner surface. The elastic material in the recess preferably has a greater height than the recess itself, so that it projects beyond the recess and protrudes from the inner surface. In this way, the elastic material can, on the one hand, exert its sealing effect and, on the other hand, compensate for tolerances to a certain extent.

[0024] According to an advantageous embodiment, the web for applying a preload force to the locking element is designed with a convex shape. This ensures that, in the locked state of the sealing clip, where the web is preloaded against the convexity, it has the desired shape for an ideal positive fit, for example, a straight shape in the case of a straight top surface of the longitudinal beam profiles.

[0025] According to the invention, the first arm of the sealing clip is hooked into a first profile section. This can be a first profile section of the first longitudinal beam profile, the second longitudinal beam profile, or preferably both longitudinal beam profiles. The first profile section has, in particular, a shape corresponding to the hooking element, which allows the hooking element to engage behind the first profile section.

[0026] Preferably, the first longitudinal beam profile and the second longitudinal beam profile are aligned with each other. For example, the longitudinal beam profiles can be connected using connecting pins, which can be accommodated in screw channels in the profiles. Particularly with such an alignment, the first arm can be provided in the first profile section of the first longitudinal beam profile as well as in the first profile section of the second longitudinal beam profile.

[0027] According to the invention, the second arm of the sealing clip is engaged in a second profile section. This can be a second profile section of the first longitudinal beam profile, or preferably of the second longitudinal beam profile, or of both longitudinal beam profiles. The second profile section preferably has a counter-engaging element corresponding to the engagement element. Preferably, the second arm is engaged in both the second profile section of the first longitudinal beam profile and the second profile section of the second longitudinal beam profile, particularly in the case of the aligned longitudinal beam profiles.

[0028] According to an advantageous embodiment of the roofing device, the first profile section is located on a visible side and the second profile section on a side of the longitudinal beam profiles that is concealed when assembled. This eliminates the need for a locking mechanism on the visible side, which would be detrimental from a design perspective. Instead, the second arm, which is visually uniform and thus easily integrated into the overall appearance, can be advantageously hooked onto a uniform contour of the visible side, requiring no local modification of the first profile section. The locking mechanism is therefore relocated to an area invisible when assembled, where design considerations are not critical. Specifically, the first and second longitudinal beam profiles are designed as wall connection profiles. The second profile section is located on the wall connection side.Furthermore, the first longitudinal beam profile and the second longitudinal beam profile can be designed as part of a ridge beam formed from two longitudinal beam profiles joined together on a flat side, with the second profile section being provided on the flat side.

[0029] According to one embodiment, the first and / or second longitudinal beam profile has a cover projection on its upper side, which is completely covered by the sealing clip in the joint area. The front end of the cover projection forms, in particular, the first profile section into which the first arm is hooked. The cover projection, for example, covers the area of ​​a rafter bracket that can be hooked into the longitudinal beam profile from above. The cover projection offers the advantage that the entire mechanism of the rafter bracket can be protected from moisture and weathering in this way. If the cover projection is sealed in the joint area, no water can penetrate into the area of ​​the rafter bracket, even in the joint area.

[0030] According to one embodiment of the inventive method, the first arm is hooked onto a cover projection of the first and / or second longitudinal beam profile that is visible in the assembled state. Alternatively or additionally, the second arm is snapped onto a concealed side of the first and / or second longitudinal beam profile. This enables particularly simple and tool-free assembly, which also advantageously conceals the locking mechanisms in invisible areas from a design perspective.

[0031] Additionally, a downward-facing seal can be provided extending from the cover projection, running between the rafter bracket or an adjacent mounting profile and the cover projection. This ensures protection against penetrating moisture, insects, dust, and the like on the front side of the wall connection as well.

[0032] According to one embodiment of the inventive method, before locking the profiles into place, a longitudinal joint between the first and second longitudinal beam profiles is first sealed with a jointing material. In the case of a wall connection profile, this can be a wall joint, i.e., a joint between the wall and the wall connection profile, or in the case of a ridge beam profile, a center joint, i.e., a joint between two longitudinal beam profiles arranged back-to-back. The second arm of the sealing clip is then pressed into the still-soft jointing material to lock it into place. In this way, the jointing material is also forced into any cavities between the longitudinal beam profile and the sealing clip, thus creating a supplementary sealing function.

[0033] According to further training, the longitudinal joint in the butt area is sealed a second time with sealant after locking. The sealant is thus applied again over the sealing clip along the longitudinal joint. This closes the joint between the sealing clip and the wall in the case of a wall connection profile, and the center joint in the area of ​​the sealing clip in the case of a ridge beam profile.

[0034] The above embodiments and further developments can be combined with one another as desired, provided they are sensible and consistent with the scope of the claims. Further possible embodiments, further developments, and implementations of the invention also include combinations of features of the invention described previously or subsequently with regard to the exemplary embodiments, even if not explicitly mentioned, insofar as they remain within the claimed scope of the invention.

[0035] 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, within the limits defined by the claims. CONTENT OF THE DRAWING

[0036] The present invention will be explained in more detail below with reference to the exemplary embodiments shown in the schematic figures of the drawing. These show: Fig. 1 a schematic side view of a sealing clip; Fig. 2 a side view of a sealing clip according to a further embodiment; Fig. 3 a bottom view of a sealing clip; Fig. 4 a perspective view of a longitudinal beam arrangement for a roofing device; Fig. 5 a cross-sectional view of the longitudinal beam arrangement according to Fig. 4; Fig. 6A-D cross-sectional views of steps for sealing a butt joint of a longitudinal beam arrangement; and Fig. 7 a cross-sectional view of a longitudinal beam arrangement according to a further embodiment.

[0037] The accompanying figures of the drawing are intended to provide a further understanding of the embodiments of the roofing device or the method of the invention.

[0038] They illustrate embodiments and, in connection with the description, serve to explain the principles and concepts of the roofing device or the method of the invention. Other embodiments and many of the aforementioned advantages become apparent with regard to the drawings. The elements of the drawings are not necessarily shown to scale.

[0039] In the figures of the drawing, identical, functionally equivalent and similarly acting elements, features and components - unless otherwise stated - are each provided with the same reference symbols. DESCRIPTION OF EXAMPLES OF EXECUTION

[0040] Fig. 1 shows a schematic side view of a sealing clip 1.

[0041] The sealing clip 1 serves to seal a joint between longitudinal beam profiles. It is intended for sealing wall connection profiles or ridge purlin profiles of roofing structures, for example, patio roofs.

[0042] The sealing clip 1 has a web 2, a first arm 3 adjoining a first side of the web 2, and a second arm 4 adjoining a second side of the web 2. Both arms project from the web in the same direction.

[0043] The first arm 3 is designed to engage behind a first profile section of a longitudinal beam profile and has a suspension element 5 for this purpose. As an example, the suspension element 5 here has a round or curved hook shape which undercuts a lateral section of the web. Of course, other types of suspension elements, in particular other hook shapes, would also be conceivable.

[0044] The second arm is designed to engage with a second profile section and features a locking element 6 for this purpose. As an example, the locking element 6 is designed here as a locking hook. Of course, other types of locking elements would also be conceivable, such as locking recesses or projections, spring-loaded elements (e.g., pins or balls), or the like.

[0045] The bridge 2 has a surface facing away from arms 3, 4 and an inner surface 7 opposite the surface, laterally bounded by arms 3, 4.

[0046] The shape of the first arm 3 and the second arm 4 is designed such that the first arm 3 can be hooked onto a first profile section of a longitudinal beam profile and the entire sealing clip 1 can then be rotated in a hooked state, so that the second arm 4 can come into contact with the longitudinal beam profile and snap into a second profile section of the longitudinal beam profile.

[0047] The shape of the sealing clip 1, in particular the shape of the inner surface 7 and the arms 3, 4, is adapted to the respective profile such that, in a locked state, the inner surface 7 rests positively on the profile. The locking element 6 of the second arm 4 is designed such that it is able to apply a preload force to the web 2, which presses the inner surface 7 against the profile.

[0048] Fig. 2 shows a side view of a sealing clip according to another embodiment.

[0049] In this embodiment, as already mentioned in relation to Fig. 1 explained, a bridge 2, a first arm 3 with a curved hook-shaped attachment means 5 and a second bridge 4 with a locking hook-shaped locking means 6 are provided.

[0050] Unlike Fig. 1An elastic material 8 is applied to the inner surface 7. This elastic material serves to improve the seal against a longitudinal beam profile. A continuous strip of the inner surface 7, extending from the first arm 3 to the second arm 4, is covered with the elastic material 8. On the first side of the web 2, the elastic material 8 extends into the first arm 3 and abuts the suspension element 5, which is designed here as a tapered, curved round hook with an increasing curvature. The elastic material thus extends into the curve of the hook shape, approximately to half its length. In a mounted state, the elastic material reaches to the foremost point of the curve, or rather, the curved inner surface, and thus seals the entire top surface of the longitudinal beam profile.Furthermore, the elastic material in the area of ​​curvature also serves to compensate for tolerances, as it can yield in the area of ​​curvature and thus compensate for any tolerances in the profile width of the longitudinal beam profile or in the clamp width of the sealing clamp as well as any differences in thermal expansion.

[0051] Apart from the locking element 6, the second arm 4 also has an inclined sealing section 14, which is formed with an inclined inner surface section. The elastic material 8 extends into the sealing section 14, so that the sealing section 14, together with the elastic material 8, can conform to a profile side edge of a longitudinal beam profile.

[0052] A recess 15 is provided on the inner surface 7 to accommodate the elastic material 8, which is received, for example, by gluing it in place. The elastic material 8 can, for example, be provided as an elastomeric strip that has a greater height than the recess 15. Thus, the elastic material 8 projects on the inner surface 7 beyond the material of the web 2 and the arms 3, 4, as shown in Fig. 2 recognizable.

[0053] The second jetty is located in Fig. 2Barely perceptible to the naked eye, slightly convex, i.e., formed with a slight curvature which opposes the feed direction of the second arm 4 for engagement. In this way, when the upper surface 24 of a longitudinal beam profile is flat, the second arm 4 is under preload in the engaged state, so that a preload force acts on the locking element 6 and thus also a corresponding reaction force on the inner surface 7 and the first arm 3. In this way, a positive locking connection of the inner surface 7 to the profile to be sealed is ensured, and the preload enhances the sealing effect achievable with the elastic material 8.

[0054] Fig. 3 shows a bottom view of a sealing clip 1.

[0055] In this view from below, which shows a top view of the inner surface 7, the first arm 3 and the second arm 4 extend over the entire length of the web 2 and are spaced apart from each other by the width of the web 2.

[0056] Three strips 9, 10, 11 made of elastic material extend across the width of the web 2. A first strip 9 extends along a first longitudinal edge 12 of the inner surface 7, and a second strip 10 extends along an opposite second longitudinal edge 13 of the inner surface 7. A third strip 11 runs centrally between them, parallel to the first strip 9 and the second strip 10.

[0057] A uniform gap 16 is provided between each of the three strips 9, 10, and 11. The first and second strips 9 and 10 serve primarily to retain moisture. The middle strip 11 serves to completely cover a butt joint. The gap 16 thus forms a channel in which any moisture that may penetrate or condense on the first or second strips 9 and 10, despite the seal, can collect and potentially evaporate.

[0058] In another embodiment, it would also be conceivable to fill the gap created by the protruding elastic material 8 in the area of ​​the distance 16 with an additional sealant, for example silicone or the like.

[0059] Fig. 4 shows a perspective view of a longitudinal beam arrangement 20 for a roofing device.

[0060] The longitudinal beam arrangement 20 comprises a first longitudinal beam profile 21 and a second longitudinal beam profile 23 directly adjoining it in a joint area 22. In the joint area 22, a top surface 24 of the longitudinal beam profiles 21, 23 is fitted with a sealing clip 1 according to Fig. 2 or 3 sealed.

[0061] In the illustrated embodiment, the longitudinal beam profiles 21, 23 are wall connection profiles for a patio roof. The longitudinal beam arrangement 20 is thus designed as a multi-part or composite wall connection for a patio roof. The front or visible side of the wall connection is shown here.

[0062] The longitudinal beam profiles 21, 23 are arranged in a butt joint and connect directly to one another, preferably with complete overlap and a zero gap. To achieve the tightest possible tolerances for such a butt joint, the longitudinal beam profiles are connected by connecting pins 32, which are inserted into screw channels in the respective profiles and thus align the longitudinal beam profiles flush with one another. In particular, at least two, preferably at least three, such connecting pins 32 are provided. The connecting pins also contribute to maintaining the load-bearing capacity of the wall connection across the joint.

[0063] The longitudinal beam profiles 21, 23 have a bearing profile section 18 designed for supporting the rafter bracket 3. The bearing profile section 18 is formed with a partially rounded shape, here by way of example a hollow circular cylinder, which is connected in one piece to a wall connection area of ​​the longitudinal beam profiles 21, 22 via support struts 19. Accordingly, the bearing profile section 18 is preferably formed in one piece with the other parts of the respective longitudinal beam profile 21 or 22.

[0064] The longitudinal beam profiles 21, 22 are designed as extruded profiles, in particular made of aluminum. Other extrudable materials, for example plastics, would also be conceivable as an alternative or in addition.

[0065] The longitudinal beam profiles 21, 22 have, by way of example, two insertion sections 17, which are provided for the insertion of a rafter bracket. In these insertion sections 7, the bearing profile section 4 is locally recessed, here by way of example with a secant-shaped recess.

[0066] In the illustrated embodiment, the insertion section 17 is arranged adjacent to the butt joint 22, so that a rafter holder can be inserted on either side of the butt joint. Of course, a single insertion section 7, or one provided on only one side, would also suffice for the insertion function.

[0067] An optional locking notch 29 is provided in the joint area 22, which serves as a locking device for securing a rafter bracket. The locking notch 29 is shown here as an example formed by a recess at each end of the longitudinal beam profiles 21, 23 in the bearing profile section 18, so that it is located directly in the gap. In this way, a rafter bracket can be fixed longitudinally in the joint area, while still allowing rotation about the bearing profile section 18.

[0068] The longitudinal beam profiles 21, 23 have a cover projection 30 on their upper surface 24. The cover projection 30 covers the area of ​​the bearing profile section 18 and any rafter bracket suspended therein, at least predominantly from above. The cover projection 30 offers the advantage that the entire mechanism can be protected from moisture and weathering in this way. In the joint area 22, the cover projection 30 is completely covered by the sealing clip, so that this protection also exists in the joint area 22.

[0069] Fig. 5 shows a cross-sectional view of the longitudinal beam arrangement according to Fig. 4 .

[0070] In this illustration, the connecting pins 32 and the position of the sealing clip 1 on the respective longitudinal beam profiles 21, 23 are clearly visible. Since the sealing clip 1 extends across the joint area 22, the cross-sectional view applies equally to both longitudinal beam profiles 21, 23 in the joint area 22.

[0071] The sealing clip 1 is engaged with its first arm 3 in a first profile section 25 of the respective longitudinal beam profile 21, 23. The second arm 4 of the sealing clip 1 is locked into a second profile section 26 of the longitudinal beam profile 21, 23.

[0072] In the illustrated embodiment, the first profile section 25 is formed by the front end of the cover projection 30 arranged on the visible side, which is positively engaged or behind-engaged by the suspension means 5 of the first arm 3 in the form of a round hook.

[0073] The second profile section 26 is provided on a side of the longitudinal beam profiles 21, 23 in the wall connection area that is concealed in the assembled state. This section has a corresponding locking element 31 in the form of a locking recess, which corresponds to the locking element 6 of the second arm 4, which is designed as a locking hook. In the assembled state, the locking mechanism is therefore invisible from the outside.

[0074] The Fig. 6A-D show cross-sectional views of steps for sealing a joint area 22 of a longitudinal beam arrangement 20.

[0075] Fig. 6A shows a side view of two longitudinal beam profiles 21 and 23 mounted in a butt joint on a wall 33, as in relation to the Figures 4 and 5 described. The longitudinal beam arrangement 20 thus forms a wall connection for a roofing device, for example a patio roof.

[0076] The longitudinal beam profiles 21, 23 are anchored in the wall 33, for example, by screw bolts 34, which are shown schematically here for clarity. Sealing materials can be inserted between the longitudinal beam profiles 21, 22 and the wall 33 during installation to prevent moisture from penetrating behind the wall connection.

[0077] After installation, a longitudinal joint 27 of the longitudinal beam profiles 21, 23 is usually sealed with a sealing material 28, for example silicone, along the entire length of the wall connection. However, it would also be conceivable to do without such sealing.

[0078] Provided, for example, in the configuration after Fig. 5As shown, several longitudinal beam profiles 21, 23 are arranged in a butt joint. A method according to the invention for sealing a butt joint 22 of a first and a second longitudinal beam profile 21, 23 is provided according to claim 11. The method comprises a first step of attaching the first arm 3 of the sealing clip 1 according to claim 11. Figs. 1 to 3 on the first profile section 25. In a second step, the second arm 4 of the sealing clip 1 is latched onto a second profile section 26.

[0079] As in relation to Figs. 4 and 5 As described, the first profile section is provided in particular on a cover projection 30 of the longitudinal beam profiles 21, 23. Since the sealing clip 1 extends over a joint area 22 of the longitudinal beam profiles 21, 23, it is preferably hooked onto the cover projection 30 over the joint area 22 and thus onto both longitudinal beam profiles 21, 23 simultaneously.

[0080] The second profile section 26 is located in particular on a concealed wall connection side of the longitudinal beam profiles 21, 23. Here too, the sealing clip 1 is preferably engaged over the joint area 22 and thus on both longitudinal beam profiles 21, 23.

[0081] To attach the sealing clip 1, it is first placed at an angle on the first profile section 25, as shown in Fig. 6 B As shown, a front end of the cover projection 30 is inserted into the suspension means 5, here by way of example a tapered curved hook, of the first arm 3.

[0082] For subsequent locking, the sealing clip 1 is rotated around the front end of the cover projection 30, so that the second arm 4 with its locking element 6 engages with the second profile section 26, as shown in Fig. 6CThe sealing clip 1, which is slightly convex in the area of ​​the web 2, is thus pre-tensioned against the surface of the longitudinal beam profiles 21, 23, thereby achieving a sealing effect at the interface between the inner surface 7 or the elastic material 8 provided thereon and the upper surface 24 of the longitudinal beam profiles 21, 23. Furthermore, the sealing section 14 with its inclined inner surface is brought into contact with a corresponding inclined section of the upper surface 24 of the longitudinal beam profiles 21, 23.

[0083] Preferably, to lock the second arm 4 into place, it is pressed into the still-softened joint sealant 28 at the longitudinal joint 27. This distributes the joint sealant around the locking element 6 and the second arm 4, thus advantageously sealing the second arm 4 against the wall 33. To ensure a seal at the top, the longitudinal joint 27 in the butt joint 22 is additionally sealed with joint sealant 28 after locking. For this purpose, the joint sealant 28 is applied again over the sealing clip 1 at the joint 27, as shown in Fig. 6D shown so that the second arm 4 is covered with jointing material 28 on the surface of the sealing clip 1 and the tightness of the longitudinal assembly joint 27 is thus also ensured in the joint area 22.

[0084] Fig. 7 shows a cross-sectional view of a longitudinal beam arrangement 20' of a roofing device according to a further embodiment.

[0085] This embodiment differs from Figs. 4 to 6 This is because the longitudinal beam profiles 21, 23 do not form a wall connection, but rather a ridge beam. To form a ridge beam, two longitudinal beam profiles are arranged laterally back to back and fastened together, for example, by means of screw bolts 34, which are shown here only schematically for clarity. The longitudinal beam profiles arranged next to each other run parallel to one another, so that in a joint area 22, two longitudinal beam profiles form a butt joint parallel to each other. The concealed side of the longitudinal beam profiles 21, 23 thus represents a median plane of the ridge beam.

[0086] Even with a ridge beam, a longitudinal assembly joint can be formed on the upper side 24 of the longitudinal beam profiles 21, 23 in relation to Fig. 6The joint is sealed as described. A jointing material 28 is inserted into the longitudinal joint on the upper surface 30 between the two back-to-back longitudinal beam profiles. In particular, two opposing sealing clips 1 are then pressed into the still uncured jointing material 28, and the assembly joint in the butt area 22 is subsequently sealed again over the sealing clips 1.

[0087] Although the present roofing device and the present method of the invention have been fully described above with reference to preferred embodiments, they are not limited thereto, but can be modified in a variety of ways within the scope of the claims. For example, the suspension element 5 need not necessarily be designed as a round hook. Rather, a wide variety of shapes corresponding to the first profile section 25 are conceivable, whereby the interlocking or the interlocking behind the profile is of primary importance for the positive locking or the positive locking fastening in the latched state.

[0088] The same applies to the design of the locking devices 6, which do not necessarily have to be designed as locking hooks. Instead, a wide variety of locking device types can be provided, the main focus being on the preload that can be applied to the sealing clip 1 to ensure sealing with the top surface 24 of the longitudinal beam profiles.
