Description

AREA OF INVENTION

[0001] The present invention relates to a patio roof with a ceiling connection. Furthermore, the invention relates to a method for mounting a longitudinal support profile of such a patio roof. TECHNICAL BACKGROUND

[0002] Longitudinal beam profiles are used for various applications. For example, they can be installed on surfaces accessible from only one side. In this case, the longitudinal beam profiles can serve as ceiling or wall connections, for instance, for roofing structures. The longitudinal beam profiles are often anchored to the wall or ceiling using fasteners such as bolts or screws. Due to the fact that the longitudinal beam profiles are only accessible from one side in these cases, installation from the back of the ceiling or wall is not possible. US 2006 / 026924 A1 discloses a profile that, in the form of a purlin, can serve as a support for several rafters. The profile is U-shaped and oriented with the legs open downwards. The area between the legs serves as the mounting surface on which the rafters rest.

[0003] EP 0 139 777 A1 discloses a profile element of a window construction attached to a roof structure, for example, a glass roof. The profile element is U-shaped, with a first leg connected to the roof structure by a fastener. The second leg is longer than the first leg, so that the fastener is concealed.

[0004] GB 2 347 945 A shows a profile element for attaching a rain gutter to a glazed roof. The profile is L-shaped. A fastener is attached to the upper end. The rain gutter is attached to the fastener by means of an insulated profile.

[0005] US Patent 4,872,297 A shows a two-part fastener used to attach a roof panel to a wall panel. The roof panel is placed on the fastener and secured there.

[0006] GB 2 101 654 A describes a greenhouse. The greenhouse comprises glass panes supported by glazing beads. One profile forms part of a ventilation duct attached to the roof structure. Four supports form a rectangular, horizontal chamber that constitutes the ventilation duct. The supports are attached to the glazing beads from below.

[0007] Document US 4,872,297 shows a multi-part mounting bracket used to attach roof panels to wall elements of a deck or similar structure. The first element of the mounting bracket is screwed to the wall, and then a second element is attached or threaded onto it. The second element must then be screwed to the first.

[0008] A disadvantage of such fastening elements is that either the fasteners remain visible from the outside after final assembly, or the supports are only suitable for fastening to walls or ceilings where the fasteners are arranged on the support opposite the mounting side of another element, such as a rafter or ceiling panel.

[0009] For example, if a roof structure is to be suspended from below to a ceiling connection, such as a roof overhang, the side of the beam with the fasteners is not opposite the mounting side for, say, rafters or ceiling panels. Therefore, angle brackets are often used as adapters between the ceiling or wall and the longitudinal beam profile. Longitudinal beams, and subsequently other elements such as rafters, can be attached laterally to these angle brackets. A disadvantage is that the screws or bolts connecting the angle bracket to the beam remain visible even after the rafters have been installed. SUMMARY OF THE INVENTION

[0010] Against this background, the present invention aims to provide an improved terrace roof with a ceiling connection and a method for assembly.

[0011] According to the invention, this problem is solved by a terrace roof with the features of claim 1 and by a method with the features of claim 11.

[0012] Accordingly, the following is planned: A terrace roof with a ceiling connection, in particular with a roof overhang, wherein a longitudinal beam profile is attached to the ceiling connection, comprising: a mounting side with at least one mounting means designed for mounting on the ceiling connection, wherein the mounting side is provided for alignment with a surface of the ceiling connection, and a visible side which has a mounting-means-free, in particular smooth and mounting-means-free, surface and is provided for alignment transversely to the surface of the ceiling connection, wherein the at least one mounting means is arranged in an undercut area of ​​the mounting side which the remaining longitudinal beam profile at least partially overlaps, so that in the mounted state of the longitudinal beam profile at the ceiling connection the at least one mounting means is invisibly concealed from the visible side, characterized in thatthat the longitudinal beam profile is designed to support a rafter bracket and has a bearing profile section designed for this purpose, which at least partially overlaps the at least one mounting means. A method for mounting a longitudinal beam profile of a terrace roof according to the invention, comprising the steps of: providing the longitudinal beam profile and contacting the mounting side of the longitudinal beam profile with a surface of the ceiling connection, in particular the roof overhang, in a position offset by a predetermined distance t1 with respect to a final mounting position; drilling with the aid of the mounting means; removing the longitudinal beam profile and performing a final drilling with a drill diameter corresponding to a fastener; and reattaching the longitudinal beam profile in the final mounting position and attaching a fastener with the aid of the mounting means, wherein the fastener is arranged in the undercut area of ​​the mounting side.which at least partially overlaps the remaining longitudinal beam profile.

[0013] The underlying insight of the present invention is that a visible side of a ceiling connection can be designed to be more aesthetically pleasing and of higher quality if no mounting means are provided on it in the installed state.

[0014] The underlying idea of ​​the present invention is that the at least one mounting means is arranged in an undercut area on a mounting side, which the remaining longitudinal beam profile at least partially overlaps. In this way, in a mounted state, the at least one mounting means is invisibly concealed from the visible side, and the visible side is thus advantageously free of mounting means and can therefore be formed smoothly.

[0015] Furthermore, this design allows for simple and quick installation of the longitudinal beam profile at a ceiling connection without additional adapter elements. In particular, no additional brackets or similar components are required for ceiling connection installation.

[0016] Furthermore, this method advantageously allows longitudinal beam profiles to be designed with known dimensions for known connection areas of rafter brackets and the like, so that the longitudinal beam profile can be combined with known systems. This makes the longitudinal beam profile suitable for mounting at a ceiling connection, such as a roof overhang, and allows it to be used for various roofing systems.

[0017] The mounting surface can have different designs; for example, it can be a flat surface. At least one mounting element can be integrated into the mounting surface. This allows the surface of the mounting surface to be in full contact with a ceiling connection when aligned with that surface.

[0018] It is also possible for the mounting surface to have a flat surface, at least in some sections. In such a configuration, the mounting surface can, for example, have a groove into which a seal, such as a joint sealing tape, can be inserted. The mounting element can be positioned at least partially on the flat surface and partially within the groove. This allows selected elements of the mounting element to be protected from moisture ingress.

[0019] A mounting element is any type of component that is either designed as a fastener on its own or, in combination with at least one other fastener, enables the attachment of the longitudinal beam profile to the ceiling connection. The mounting element is preferably at least partially integrated into the mounting surface. A detachable connection between the longitudinal beam profile and the ceiling connection can be established.

[0020] Furthermore, the mounting element is at least partially concealed by the remaining longitudinal beam profile. The remaining longitudinal beam profile consists at least of the mounting element-free surface, which forms a visible side, and may have additional areas. When installed, the visible side is oriented perpendicular to the surface of the ceiling connection and can therefore be viewed from a position below the ceiling connection. The visible side has neither mounting elements nor any additional adapter elements. Consequently, the visible side can be flush with the surface of the ceiling connection, creating an aesthetically pleasing surface. The visible side can thus be designed in any desired way. In addition to a completely smooth surface, smooth surfaces with decorative grooves or edges, as well as radii of the longitudinal beam profile, are also conceivable.In particular, a smooth surface on the visible side is therefore understood to mean a surface that can be designed in terms of design aspects, in the absence of recesses, holders or the like required for assembly.

[0021] Furthermore, the longitudinal beam profile is designed with a constant cross-sectional shape in the longitudinal direction.

[0022] The method for mounting a longitudinal beam profile is in particular a method for mounting a longitudinal beam profile for a roofing device.

[0023] 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.

[0024] According to an advantageous embodiment, the longitudinal beam profile can be formed in one piece. This reduces the number of parts and simplifies assembly. Alternatively or additionally, the longitudinal beam profile can be formed as a deep-drawn profile. Advantageously, a deep-drawing process allows both the visible side and the mounting side to be produced cost-effectively in a single profile.

[0025] According to a further development, the longitudinal beam profile can be designed as a partially open hollow profile, with one open side adjoining the mounting side. In this way, the undercut area of ​​the mounting side, which the remaining longitudinal beam profile at least partially overlaps, can be arranged, for example, on one leg of a partially open hollow profile with a U-shaped cross-section. An opposite leg of the U-shaped cross-section can form the overlapping area. In such a design, the visible side can be located in the central region of the U-shaped cross-section.

[0026] According to one embodiment, the surface free of mounting hardware can be formed essentially perpendicular to the mounting side. "Essentially perpendicular" includes small deviations from a vertical orientation, for example, less than 10°. However, it can also refer to an orientation perpendicular to the mounting side. In particular, the surface free of mounting hardware is vertically oriented in the mounted state. Advantageously, in this way, the visible side is positioned below the ceiling connection and is visible from the building side when the surface is mounted.

[0027] According to an advantageous embodiment, the mounting-free surface can have rounded edges in the perimeter region. This advantageously provides a harmonious transition between the longitudinal beam profile and the surface of the ceiling connection, as well as to the underside of the longitudinal beam profile.

[0028] According to a preferred embodiment, the at least one mounting means can have a first bore with a first diameter and a second bore with a second, smaller diameter, wherein the bores are spaced apart from each other in a transverse direction of the longitudinal beam profile and arranged at the same height in the longitudinal direction, and the longitudinal beam profile overlaps the first bore in the transverse direction. In this way, the first bore can be arranged at a mechanically necessary position in the transverse direction of the longitudinal beam profile, so that the longitudinal beam profile can be stably mounted to the ceiling connection. The second bore with the smaller diameter can be arranged in the transverse direction such that it is not overlapped in the transverse direction by a further section of the longitudinal beam profile.Advantageously, this makes the second bore accessible from outside the longitudinal beam profile, since a central axis of the second bore does not intersect the cross-section of the longitudinal beam profile at any position except at the bore itself.

[0029] According to a particularly preferred embodiment, the mounting device can have at least one mounting hole and a drilling template, wherein the mounting hole, when the longitudinal beam profile is mounted, is located opposite the mounting side and concealed from view from the visible side, and the drilling template is integrated into the longitudinal beam profile. Advantageously, the drilling template is accessible with a drilling tool from a position opposite the mounting side and outside the cross-section of the longitudinal beam profile. This allows the drilling template to be used for drilling the mounting hole, which would otherwise be difficult or impossible to access with a drilling tool. According to an advantageous embodiment, the first hole can be designated as the mounting hole and the second hole as the drilling template.Advantageously, after drilling with the drilling template, the longitudinal beam profile can be shifted so that the first hole is moved to the position of the pre-drilled hole, and a fastener, such as a screw, is inserted through the fastening hole. This allows the fastener to be positioned in the undercut area, so that it is overlapped and covered by the longitudinal beam profile.

[0030] According to the invention, the longitudinal beam profile is designed to support a rafter bracket and has a bearing profile section designed for this purpose, which overlaps the at least one mounting means at least partially, in particular horizontally. In this way, the bearing profile section can be sufficiently stable and designed in a mechanically and geometrically advantageous position.

[0031] According to one embodiment, the mounting surface can be attached to the ceiling connection in direct contact with the assembled surface. In particular, full-surface contact is possible, but it can also be essentially full-surface contact with a sealing groove provided therein. Advantageously, this allows for rotationally secure mounting of the longitudinal beam profile at the ceiling connection.

[0032] According to an advantageous embodiment of the method for mounting a longitudinal beam profile, the pilot hole can be drilled with a smaller diameter than the final hole. Advantageously, the pilot hole serves to position a subsequent final hole, and the pilot hole is preferably drilled using a drilling template integrated into the longitudinal beam profile. In particular, the mounting device has at least one fastening hole and a drilling template, with the fastening hole and the drilling template preferably both being integrated into the longitudinal beam profile.

[0033] According to an advantageous embodiment of the method, the drilling can be carried out from a position opposite the mounting side and outside the longitudinal beam profile. In this way, a suitably robust tool, such as a hammer drill, can be used for the initial drilling, with which a pilot hole can be drilled into the ceiling connection.

[0034] According to an advantageous embodiment of the method, the fastener can be attached from a position at least partially within the longitudinal beam profile and / or offset laterally with respect to the mounting side. Advantageously, the fastener can be inserted into the cross-section of the longitudinal beam profile as well as into the end bore. Final assembly can be carried out with a tool from a lateral position outside the longitudinal beam profile, for example, from an open side of the longitudinal beam profile.

[0035] The above embodiments and further developments can be combined with one another as appropriate. In particular, all features of the longitudinal beam profile can be transferred to the method for assembling the longitudinal beam profile, and vice versa. 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. In particular, those skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the present invention without deviating from the scope defined by the appended claims.

They illustrate embodiments and, in conjunction with the description, serve to explain the principles and concepts of the invention. Other embodiments and many of the advantages mentioned will become apparent with reference to the drawings. The elements of the drawings are not necessarily shown to scale.

[0038] 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

[0039] Fig. 1 Figure 1 shows a roofing device 1 with a longitudinal beam profile 2 in a perspective view.

[0040] The roofing device 1 has a longitudinal beam profile 2 designed as a wall connection profile, which is mounted to a ceiling connection 4. The longitudinal beam profile 2 runs along the ceiling connection 4 and is attached to the ceiling connection 4 from below.

[0041] Fig. 2 shows an enlarged view of section A1 according to Fig. 1 in a side view.

[0042] A mounting side 5 of the longitudinal beam profile 2 is in full contact with a surface 3 of the ceiling connection 4.

[0043] In this side view, the longitudinal beam profile 2 is closed at the edge by an end element 22, so that a cross-section of the longitudinal beam profile 2 is not visible. Rafters 15 are mounted on the longitudinal beam profile 2 opposite a visible side 18. These can be anchored to the longitudinal beam profile 2 by means of rafter brackets, which are concealed in this view by the end element 22.

[0044] Fig. 3 Figure 2 shows a longitudinal beam profile 2 in a perspective sectional view.

[0045] In this view, it can be seen that the left-hand outer surface forms a visible side 18 with a mounting-free surface 7. This visible side 18 can be flush with the surface 3 of the ceiling connection 4 when installed. For this purpose, the visible side has rounded edges 13, which are designed as chamfered radii with form transitions to the visible side. This ensures a harmonious transition and an aesthetically pleasing appearance of the longitudinal beam profile 2 at the ceiling connection 4 when installed.

[0046] The mounting side 5 is arranged essentially perpendicular to the visible side 18. In the illustrated embodiment, 6 bores 9 are arranged on the mounting side 5 as mounting means. The bore 9 on the left in the illustration serves as the fastening bore 10. The bore 9 on the right in the illustration is designed as a drilling template 11. The drilling template 11 has a smaller diameter than the fastening bore 10. This allows the drilling template 11 to be used to initially drill a hole with a smaller diameter. The two bores 9 are spaced apart from each other in the transverse direction X of the longitudinal beam profile 2. In the longitudinal direction Y, the two bores 9 lie on the same line. This means that after drilling, the longitudinal beam profile 2 only needs to be offset by the distance between the two bores 9 to be mounted in a final position with the fastening bore 10.

[0047] In this embodiment, the drilling template 11 is arranged in a groove 20. A seal can be inserted into this groove 20 for assembly purposes in order to protect a fastener inserted in the mounting hole 10 from the ingress of moisture from the weather side.

[0048] In this embodiment, the longitudinal beam profile 2 is designed as a partially open hollow profile and has a substantially U-shaped cross-section. The mounting side 5 adjoins an open side 8. A bearing profile section 12 is arranged inside the longitudinal beam profile 2. This is designed to support a rafter bracket.

[0049] The longitudinal beam profile 2 is designed as an extruded profile by way of example. In particular, it contains aluminum. Other extrudable materials, for example plastics, would also be conceivable as alternatives or in addition.

[0050] Fig. 4 Figure 2 shows another embodiment of a longitudinal beam profile 2 in a perspective sectional view. The longitudinal beam profile 2 differs from the one shown in Figure 2. Fig. 3 This is due to its larger cross-sectional dimensions. The cross-sectional height of the different longitudinal beam profiles 2 can, for example, range between 100 mm and 200 mm.

[0051] Fig. 5 Figure 1 shows another embodiment of a longitudinal beam profile 2 in a perspective view with detailed representation of the mounting means 6.

[0052] The longitudinal beam profile 2 has a mounting device 6 at each of two positions A2. The mounting devices 6 are identical and are shown enlarged in the lower part of the illustration. It can be seen that the drilling template 11 has a smaller diameter than the fastening hole 10.

[0053] Fig. 6 shows assembly steps for mounting a longitudinal beam profile 2 to a ceiling connection 4 in a side view.

[0054] The illustration shows, on the one hand, the drilling process step using a drilling tool 14. The drilling is carried out from a position opposite the mounting side 5 and outside the longitudinal beam profile 2, using the drilling template 11. Therefore, during drilling, the longitudinal beam profile 2 is offset by the distance t1 from a final assembly position at the ceiling connection 4.

[0055] On the other hand, the illustration also shows the reattachment of the longitudinal beam profile 2 in the final assembly position. The position of the longitudinal beam profile 2 in the final assembly position is labelled 2' for clarity.

[0056] Fig. 7 Figure 1 shows the longitudinal beam profile 2' arranged in the final assembly position in the assembled state at the ceiling connection 4 in a side view.

[0057] The mounting hole 10 and the drilling template 11 are arranged at a distance t1 from each other in the transverse direction X. The distance t1 can be, for example, 20-40 mm, in particular 25-30 mm.

[0058] The drilling template 11 lies in a groove 20 in which a seal 16, for example a joint sealing tape such as a compression tape, is arranged. On the right side of the illustration, a silicone joint 17 is also arranged on the mounting side 5 between the longitudinal beam profile 2' and the ceiling connection 4. The seal 16 and the silicone joint 17 protect the mounting element 6, in particular the fastening hole 10 with a fastener 21 installed therein, from penetrating moisture from the weather side.

[0059] In this representation in Fig. 7It is evident that a drilling template axis S is accessible from a position opposite mounting side 5 and outside the longitudinal beam profile 2'. However, a projection P in the lower area of ​​the longitudinal beam profile 2' overlaps the fastening hole 10 or a fastening hole axis B, so that the fastening hole 10 is located in an undercut area of ​​the mounting side 5. The fastening hole 10 and a fastener 21 installed therein are not visible from the visible side 18 or from a position below the longitudinal beam profile 2'.

[0060] The fastener 21 can be mounted at least partially within the longitudinal beam profile 2' and / or offset in the transverse direction X with respect to the mounting side 5. This is possible by drilling an end hole with a diameter corresponding to the fastener 21 with the longitudinal beam profile 2' removed, whereby the drilling template 11 and the previously made pilot hole allow the precise determination of the position. The fastener 21 is then mounted when the longitudinal beam profile 2' is in the final assembly position as shown.

[0061] In this embodiment, the bearing profile section 12 also overlaps the fastening bore axis B in the transverse direction X. The fastening bore 10 and the bearing profile section 12 are arranged in a mechanically advantageous position approximately on the fastening bore axis B on the longitudinal beam profile 2'. This ensures stability both between the fastening of the longitudinal beam profile 2' and the ceiling connection 4, and between the bearing profile section 12 and the rafters suspended therein.

[0062] Although the present invention has been fully described above with reference to preferred embodiments, it is not limited thereto, but can be modified in a variety of ways within the scope of the attached claims. Reference symbol list
