Description

TITLE

Spacers for roof tiles

TECHNICAL AREA

The present invention relates to a spacer for roof panels of roof coverings, in particular roof coverings with large-format panels, according to claim 1 or claim 12, and to the use of the spacer in a mounting system for mounting roof coverings according to claim 25.

STATE OF THE ART

Traditional roof coverings often consist of small-format materials such as roof tiles, shingles, or slate, which are laid individually. These traditional materials are time-tested and offer good weather resistance; however, their installation on a closely spaced batten system can be time-consuming and labor-intensive. Large-format panels are increasingly used in new construction because they allow for faster and more efficient installation. These panels cover larger areas, reducing the number of joints required and improving the roof's watertightness. Furthermore, large-format panels can offer a modern aesthetic and are often lighter, thus reducing the load on the roof structure. Panel fasteners, such as spacers, are used to install these roof panels.

EP 2 784 241 A1 discloses a panel fastening element that can be used for mounting large-format roofing panels as well as photovoltaic panels, solar panels, solar modules, or solar collectors. The installation of the panel fastening element and the roofing material from EP 2 784 241 A1 can be carried out very simply and efficiently to create a weatherproof, in particular water-resistant and waterproof, roof covering. This roof covering can also be used on roofs with a low pitch and withstands high loads, requiring only a small overlap of the respective panels, modules, and/or collectors. PRESENTATION OF THE INVENTION

Based on this prior art, the present invention is based on the objective of providing a spacer that exhibits improved properties for the drainage of potential condensation. In particular, a particularly preferred objective of the present invention is to provide a spacer for roof tiles of roof coverings, especially roof coverings with large-format tiles, which is designed for targeted water drainage, in particular for channeling the condensate in the overlap area, as well as for promoting ventilation in the overlap area in order to prevent wood rot, which can occur in unfavorable cases due to recurring dampness from condensation that does not drain or dry out in the overlap area.

The object according to claim 1 solves these and other problems. Accordingly, a spacer comprises a support element. Furthermore, the spacer has a lower bearing surface for resting on a roof substructure and an upper bearing surface on which the underside of a roof panel can be supported. The support element comprises at least one water drainage element. The at least one water drainage element is designed such that, in the installed position, any condensation can be drained away through the at least one water drainage element in one flow direction.

The at least one drainage element efficiently removes any condensation. This efficient drainage prevents water from accumulating or pooling in the fastening area. In this way, potential moisture problems, especially the development of wood rot, are minimized within the system. This extends the service life of the components.

The term "water drainage element" refers to an element that is integrated into the support element in its design or construction to specifically drain condensation. A water drainage element comprises structures that prevent the accumulation of condensation and/or facilitate its removal.

Preferably the roof substructure consists of roof battens that are parallel to each other They are to be mounted on roof rafters. The term "large-format panel" preferably refers to panel sizes with a maximum dimension of 3050 x 1250 mm. Other panel sizes, particularly smaller or larger formats, are also conceivable. The panel thickness is preferably between 8 mm and 12 mm. Other panel thicknesses, particularly thinner or thicker panels, are also conceivable.

A panel, particularly a roofing panel, is preferably understood to be a fiber cement panel. The panel can also be made of another material. In other applications, the panel can be an energy-generating element, such as a photovoltaic panel. The panel can be mounted on various structures.

The support element preferably has a rectangular cross-section, in particular a cross-section of an elongated rectangle.

At least one of the water drainage elements preferably has at least one water-conducting side wall.

The side wall is designed to act as a guide for any condensation. It is integrally formed with the water drainage element and is in direct contact with the condensation. The side wall is preferably made of the same material as the water drainage element, but it can also be made of a different material.

In an alternative version of the water drainage element, the water drainage element can include a separate element that is attached to or placed over the support element or a water drainage element already present on the support element. This separate element can have a water-bearing side wall that is in direct contact with the condensate. The separate element can either completely surround the support element or the water drainage element, or it can only rest on the condensate-bearing side of the support element or the water drainage element.

The at least one water-conducting side wall preferably protrudes from a water-conducting surface on the support element. When installed, the water drainage surface forms a base from which the condensate can drain away. The condensate is channeled laterally, perpendicular to the flow direction, through at least one side wall.

The side wall is preferably molded onto the water-guiding surface. The side wall can also be attached to the water-guiding surface by means of a fastening device.

The water guidance surface is located in the installed position at a lower elevation relative to the upper bearing surface.

The term "lowered" is to be understood as meaning that, in the installed position, the water-bearing level is lower than the upper bearing surface.

Preferably, at least one side wall has at least one opening. The at least one opening is designed such that any condensation can be drained away at an angle to the flow direction.

The opening directs any condensation away from the water channeling surface. Consequently, the condensation leaves the surface of the support element.

Preferably, the water-guiding surface has at least one opening. This opening is designed in such a way that any condensation can be drained away through the water-guiding surface.

The expression "drain through the water-guiding surface" is to be understood as meaning that the at least one opening directs any possible condensation away from the water-guiding surface in a direction essentially perpendicular to the water-guiding surface.

Preferably, the at least one opening extends directly through the support element, i.e., with a minimum distance corresponding to the thickness of the support element at that point. The at least one opening can also extend obliquely through the support element, in particular having an oblique circular cylindrical shape. The following section describes specific modifications of the water drainage element in more detail. It is conceivable that only one of the described modifications is present, that several of the described modifications are present, or that all of the described modifications are present.

A first further development of one of the aforementioned water drainage elements has two side walls. The two side walls are positioned opposite each other with respect to the flow direction and spaced apart from one another. The arrangement is such that an opening is created between the two side walls for the condensate to be drained away.

The term "opening" differs from the term "breakthrough" in that, with an opening, the condensate is drained along the direction of flow. With a breakthrough, the condensate is drained at an angle to the direction of flow.

The distance between the two side walls is preferably chosen so that the condensation can be efficiently drained away.

In one variant of the first training course, two of the aforementioned side walls are arranged parallel to each other.

The term "parallel" means that the two side walls run at the same angle relative to the flow direction.

In a second embodiment of the first embodiment, two of the aforementioned side walls are arranged at an angle to the flow direction. Preferably, the side walls are straight and inclined at an angle to each other. Alternatively, the side walls are curved, in particular convexly curved, in the flow direction.

The phrase "angled inclined side walls" should be understood to mean that the angles of the two inclined side walls relative to the flow direction can be the same or different. That is, the side walls can be inclined symmetrically with identical angles or asymmetrically with different angles.

In a second training session, the support element has a subpage. At least. One of the water drainage elements protrudes from the underside of the support element. Two of the aforementioned side walls are connected to each other at the support element. The connection is such that, in the installed position, the two aforementioned side walls form a downwardly open, elongated hollow profile, which preferably has an enlarged cross-section in the flow direction.

In other words, the support element has at least one tunnel-shaped drainage element on its underside. This at least one tunnel-shaped drainage element rests on a lower roof panel, so that the support element is supported by the at least one drainage element. The resulting gap between the support element and the roof panel, as well as the tunnel-like structure of the at least one drainage element, also allows for improved air circulation.

The cross-section can widen continuously at a constant angle. Alternatively, the cross-section can widen at a constant angle over a limited area, particularly along a widening surface. After widening, the cross-section remains constant.

In a third embodiment, at least one of the aforementioned water drainage elements is arranged transversely to the flow direction. The water-conducting side wall of the aforementioned water drainage element projects in a wedge shape towards the flow direction. Preferably, a vertex is located at the highest point of this wedge-shaped structure, and the sides sloping downwards from the vertex are inclined outwards at an angle to the flow direction.

The wedge-shaped structure has the advantage of more efficient drainage of condensation. This efficiency is further enhanced by the slope of the support element in its installed position, which is provided by the roof pitch. The support element can also be designed to create a slope along the water drainage surface.

The subject matter of claim 12 is based on the objective of providing a spacer for roof panels of roof coverings, in particular roof coverings with large-format panels, which prevents the ingress of condensate into the screw channel provided for fastening the roof panels. The spacer for roof tiles, particularly roof coverings with large-format tiles, according to claim 12, solves these and other problems. Accordingly, the spacer comprises a support element. The spacer has a lower bearing surface for resting on a roof substructure and an upper bearing surface on which the underside of a roof tile can be supported. Furthermore, the spacer comprises a sealing element. The sealing element is integrated into the support element. The spacer can be mounted to a roof substructure by means of a mechanical fastening element that can be passed through the sealing element.

The passage of the fastener through the sealing element to attach the spacer to the roof substructure has the advantage of ensuring an effective seal. In particular, it prevents condensation from penetrating the screw channel. The sealing element also reduces the risk of wood rot.

The term "sealing element" refers to an element that serves to create a watertight seal between different components or surfaces. The sealing element also prevents the ingress of dirt or other external influences. Preferably, the sealing element provides a watertight seal between the fastening element and the support element. The sealing element also provides a watertight seal between the fastening element and the roof substructure, in particular the roof battens.

The sealing element can be made of various materials, especially elastic materials such as rubber, silicone, or plastic. It can also be made of other materials.

According to claim 13, the spacer comprises the features of claim 1 and the dependent claims with their optional features. Accordingly, a spacer for roof tiles of roof coverings, in particular roof coverings with large-format tiles, has a support element. Furthermore, the spacer has a lower bearing surface for resting on a roof substructure and an upper bearing surface on which the underside of a roof tile can be supported. The support element has at least one water drainage element. The water drainage element is designed such that any condensation that may occur during installation can be drained away in one direction through at least one drainage element. Furthermore, the spacer has a sealing element integrated into the support element. The spacer can be mounted to a roof substructure by means of a mechanical fastener that passes through the sealing element.

The embodiment according to claim 13 has the advantage that the at least one water drainage element specifically drains the condensation in the covering area and the sealing element prevents moisture from entering the screw channel.

The following features, which will be described later, are optionally advantageous for all spacers with the sealing element.

Preferably, the support element has a recess extending from an upper surface to a lower surface and bounded by an inner surface, in which the sealing element is arranged.

The term "recess" is to be understood as meaning that the support element has a continuous recess, in particular a cavity in the interior of the support element, which is bounded by an inner surface.

In a first variant, the sealing element preferably fills the recess flush with at least one of the two surfaces mentioned.

The term "flush" means that the surface of the sealing element is at the same level as the surrounding surface of the support element. The sealing element does not form any protrusion or depression on this surface. The surface of the sealing element is so flush with the surrounding surface that a preferably smooth, continuous surface is created.

In a second variant, the sealing element preferably protrudes from the recess with an overhanging section, such that the sealing element with the overhanging section protrudes beyond the lower surface and/or the upper surface.

The term "protrusion section" refers to an area of the sealing element. understood, which extends beyond the actual recess and its limiting inner surface.

This means that the sealing element can protrude from the recess with an overhanging section. The overhanging section can protrude either on one of the two surfaces of the support element or on both. Preferably, the overhanging section protrudes on one of the two surfaces and fills the recess flush on the opposite side.

According to a further development of the second variant, the overhanging section, viewed transversely to the central axis of the recess, has an extent corresponding to the cross-section of the recess. In an alternative further development, the overhanging section, viewed transversely to the central axis of the recess, has an extent larger than the cross-section of the recess, such that the overhanging section extends laterally to the recess, with the overhanging section resting on the respective surface in this area.

In other words, the protruding section can have an extension that extends beyond the edge of the recess. This extension extends into a region laterally to the recess, partially or completely circumferentially within this region. The extension is integrally formed with the sealing element.

Preferably, the inner surface of the recess has at least one ridge extending along its length. This ridge engages in a correspondingly shaped groove on the sealing element such that, with respect to movement in a direction perpendicular to the support element, the sealing element is firmly connected to the support element. In an alternative embodiment, the outer surface of the sealing element has at least one ridge extending along its length. This ridge engages in a correspondingly shaped groove on the inner surface of the recess such that, with respect to movement in a direction perpendicular to the support element, the sealing element is firmly connected to the support element. Furthermore, this ridge engages in a correspondingly shaped groove on the inner surface of the recess such that a surface-fit connection is established between the ridge and the groove. The term "extending along" means that the ridge is arranged along a surface. The ridge can extend continuously or intermittently, particularly as several ridges arranged one after the other, along this surface. The several ridges arranged one after the other can be at the same elevation or at different elevations. Some ridges can also be at the same elevation, forming a first group. Other ridges can form a second group, which are at a different elevation relative to the first group. The ridges of the two groups can be arranged alternately, so that each ridge of one group is at a different elevation than each ridge of the other group.

Preferably, the sealing element has a surface structure with at least one protrusion on at least one surface, in particular at least one annular protrusion. Each of the at least one protrusion provides a sealing line.

The ring-shaped ridges are accompanied by ring-shaped depressions. The depressions are positioned between the ridges. This combination of ridges and depressions contributes to improved sealing properties. The ridges and depressions enable a more effective seal and better adaptation to adjacent surfaces. The depressions contribute to better distribution of condensation. The risk of leaks is minimized by the depressions. The ingress of condensate into the screw channel is prevented by the depressions.

Preferably, at least one raised section is part of the upper storage surface.

The underside of a roof panel can be supported on the upper bearing surface of the spacer. The underside of the roof panel rests on at least one raised section. The underside of the roof panel may also rest on other points of the support element. Due to elastic deformation, the roof panel may rest on additional points of the support element. Elastic deformation can occur due to the roof panel's own weight. Additional loads on the roof panel, particularly snow loads, can also lead to elastic deformation.

Preferably, the sealing element has a centering recess. The fastening element can be passed through the centering recess. In other words, a fastener, such as a screw or similar, is drilled through the centering recess. The centering recess is located in the middle of the sealing element.

Preferably, the recess has a round cross-sectional shape.

Preferably, the support element is made of a harder material than the sealing element. Additionally, or alternatively, the support element is manufactured using a two-component injection molding process.

The harder material of the support element makes it robust and resistant to mechanical stress. The softer material of the sealing element allows for a better fit to the recess of the support element, thus improving the sealing properties.

Preferably, in all embodiments described herein, the spacer has a bearing section that projects at an angle, in particular at a right angle, from the support element. Preferably, the bearing section has at least one further continuous recess for additional fastening of the spacer to a roof substructure by means of a further fastening element.

The hook-shaped design of the spacer allows it to be hooked onto a roof batten in its installed position. Subsequent fastening, in particular by screwing or similar means, through the designated at least one further continuous recess, secures the spacer to the roof batten. This method results in a particularly secure installation with increased ease of assembly, especially for the installer working on the roof.

A mounting system for installing roof coverings, in particular roof coverings with large-format panels, comprising a spacer as described above, a roof substructure with at least a first batten and a second batten, an upper roof panel, and a lower roof panel. In a preferred embodiment, the spacer is mounted on the first batten, and the lower roof panel is placed on the second batten below the spacer, in particular such that the lower bearing surface rests on the lower roof panel. The upper roof panel is placed on the Spacers are positioned, specifically so that the upper roof panel rests on the upper bearing surface. In one variant for attaching the mounting system to the roof substructure, the fastener protrudes through the upper roof panel and through the sealing element on the spacer. In a second variant, the fastener protrudes through the sealing element on the spacer and through the lower roof panel. In a third variant, the fastener protrudes through the upper roof panel, through the sealing element on the spacer, and through the lower roof panel.

Further embodiments are specified in the dependent claims.

DESCRIPTION OF PREFERRED EXECUTION FORMS

With reference to Figures 1 to 6, a spacer 1 according to a particularly preferred embodiment will now be described in more detail. The spacer 1 has a support element 2, a lower bearing surface 3 for resting on a roof substructure 27, and an upper bearing surface 4 on which an underside of a roof panel can be supported. Furthermore, the support element 2 has at least one, here several, water drainage elements 50, 51, 52, 53, 54, 55, 56, 57, and/or a sealing element 11, which is incorporated into the support element 2. The spacer 1 is mounted to a roof substructure, in particular a roof batten, by means of a fastening element 12, which passes through the sealing element 11.

In a first embodiment, the spacer 1 comprises a support element 2 and at least one water drainage element 50, 51, 52, 53, 54, 55, 56, 57. In a second embodiment, the spacer 1 comprises a support element 2 and a sealing element 11. In a third embodiment, the spacer 1 comprises a support element 2, at least one water drainage element 50, 51, 52, 53, 54, 55, 56, 57 and a sealing element 11.

In the preferred embodiment shown, the spacer 1 is essentially hook-shaped, with a bearing section 24 bent outwards and projecting at right angles from the support element 2. The projecting bearing section 24 has two recesses 25. The two recesses 25 serve for additional fastening of the spacer 1 to a roof batten, in particular the first batten 28. Furthermore, the bearing section 24 has a surface structured with continuous recesses, in particular a grid structure 32. The grid structure 32 serves to maintain or improve the stability of the material while simultaneously saving material.

In the preferred embodiment shown, the rectangular cross-section of the support element 2 tapers over a certain area and then widens again to its original width, which preferably corresponds to the width of the support element B. The tapering of the two longitudinal sides of the support element 2 preferably does not occur linearly, but rather along a curved, concave line 34. The area between the tapering and widening has a constant width. This area is bounded by two water-bearing side walls 502, 503. The width of this area corresponds to the distance between the two side walls. The widening to the original width of the support element B occurs perpendicular to the flow direction F. The tapering has the advantage of saving material.

The underside of the support element 10 has a surface with discontinuous depressions. The grid-like structure forms reinforcing ribs 33. These reinforcing ribs 33 serve to increase structural integrity and stiffness. to improve the support element 2. The arrangement and shape of the reinforcing ribs 33 reduce the overall weight of the support element 2 and enable efficient material use.

Furthermore, the sealing element 11 and the water drainage elements 50, 51, 52, 53, 54, 55, 56, 57 are arranged between the protruding bearing section 24 and the opposite end of the spacer 1.

In the illustrated embodiment, the sealing element 11 is incorporated into the support element 2. The sealing element 11 lies in a recess 16. The recess

The recess 16 is located on the upper surface 13 and extends from this upper surface 13 to a lower surface 14 of the support element 2. The recess 16 is bounded by an inner surface 15. Furthermore, the recess 16 has a round cross-sectional shape.

Furthermore, the sealing element 11 has a centering recess 23. The centering recess 23 is located centrally on the sealing element 11. The sealing element 11 also has a surface structure with protrusions 22. The protrusions 22 are annular. Annular depressions are arranged between the annular protrusions 22. The annular protrusions 22 form part of the upper bearing surface 4, on which the underside of a roof panel rests. As can be seen from Figures 5 and 6, the upper roof panel 30 rests, among other things, on the sealing element 11, in particular on the annular protrusions 22.

As can be seen in Figures 1 to 3a, the sealing element 11 projects out of the recess 16 on the upper surface 13 with a projection section 17. On the underside 10 of the support element, the sealing element 11 fills the recess 16 flush with the lower surface 14. In the embodiment shown, the underside of the sealing element 11 has a mostly smooth, continuous surface. In the area of the centering recess 23, the underside of the sealing element 11 has a depression. In the variant according to Figure 3b, the sealing element 11 also projects out of the recess 16 on the lower surface 14 with a projection section 17 on the underside 10.

Figures 5 and 6 show the mounting system, in particular the spacer, in its assembled state. The figures show that the protruding section

17 has an extension 18. The extension 18 is formed on the sealing element 11. and is larger than the cross-section of the recess 16. The extension 18 extends into a region laterally to the recess 16. The extension 18 of the overhanging section 17 rests on the upper surface 13. The extension 18 has a round, in particular a circular, cross-sectional shape that completely surrounds the overlapping area on the upper surface 13.

Figures 5 and 6 further show that, in the illustrated embodiment, the inner surface 15 of the recess 16 has a comb 19. The comb 19 has a rectangular cross-sectional shape and is integrally formed on the inner surface 15. The comb 19 engages in a correspondingly shaped groove 20 on the outer surface 21 of the sealing element 11. The comb 19 extends along the inner surface 15 of the recess 16. The groove 20 extends along the outer surface 21 of the sealing element 11. Preferably, the sealing element 11 is made of an elastic material. This enables a particularly tight surface connection between the comb 19 and the groove 20.

In the illustrated embodiment, the water drainage elements 50, 51, 52, 53, 54, 56, 57 project from the water guidance surface 6. The water guidance surface 6 is located at a lower elevation than the upper bearing surface 4. In its installed position, the water guidance surface 6 forms a base from which the condensate can drain.

Figures 1 and 2 show that in the preferred embodiment illustrated, the spacer 1 includes, among other things, the second variant of the first further development of the water drainage elements. A first group of water drainage elements 50, 51 is arranged opposite each other and spaced apart from each other on the water-guiding surface 6 with respect to the flow direction F. The arrangement is such that the water drainage elements 50, 51 and their water-conducting side walls 500, 501 are convexly curved, and an opening 8 is arranged between the two water drainage elements 50, 51. Furthermore, a second group of water drainage elements 56, 57, which are designed and arranged identically to the water drainage elements 50, 51 of the first group, is installed above the first group. The arrangement of these two groups relative to each other is funnel-shaped. This means that any condensation that forms in the flow direction F first passes through the water-conducting side walls 506, 507 of the water drainage elements 56, 57 of the second group through the opening 8 and then through the water-conducting side walls 500, 501 of the water drainage elements 50, 51 of the The first group is led away through opening 8.

Figures 1 and 2 further show that the preferred embodiment of the spacer 1 depicted comprises the first variant of the first further development of the water drainage elements. The water-bearing side walls 502, 503 of the water drainage elements 52, 53 are parallel to each other with respect to the flow direction F and are spaced apart. The water-bearing surface 6 is bounded laterally, among other things, by the water-bearing side walls 502, 503 of the water drainage elements 52, 53, in particular so that a channel is created.

The water drainage elements 50, 51 of the first group are arranged on the water guidance surface 6 in such a way that they funnel the accumulating condensate in the flow direction F to the parallel and spaced-apart

Water drainage elements 52, 53 are discharged. The funnel-shaped structure of the water drainage elements 50, 51 projects into the channel-forming arrangement of the

Water drainage elements 52, 53 are inserted. In other words, the

Water drainage elements 50, 51 are arranged relative to water drainage elements 52, 53 such that they intersect along the flow direction F.

In the illustrated embodiment, the water-conducting side walls 502, 503 each have an opening 7. These openings 7 allow the condensate to be discharged at an angle to the flow direction.

Figures 1 and 2 further show that the preferred embodiment of the spacer 1 depicted has the third further development of the water drainage elements. The water drainage element 54 is positioned transversely to the flow direction F and, in its installed position, forms the lower end of the water-guiding surface 6. The aforementioned openings 7 in the water-conducting side walls 502, 503 are arranged between the water drainage element 54, which is arranged transversely to the flow direction F, and the water drainage elements 52, 53 of the first variant of the first further development, which are arranged parallel to and spaced apart from each other.

In the preferred embodiment shown, the water drainage element 54 has a wedge-shaped structure, with the water-bearing side wall 504 projecting towards the flow direction F. The wedge-shaped structure has a vertex S at its highest point. The point of this structure. The sides 504 descending from the vertex S run at an angle to the flow direction F towards the outside.

Furthermore, Figures 3a/3b show that the preferred embodiment of the spacer 1 depicted has the second further development. In this embodiment, four water drainage elements 55 project from the underside 10 of the support element. Each of these water drainage elements 55 has a tunnel-shaped structure bounded by the water-conducting side walls 505. As shown in Figure 3, these water drainage elements 55 have an enlarged cross-section in the flow direction F. The widening of the cross-section occurs after the opening 9 in the flow direction F. The cross-section widens at a constant angle, preferably 45°. The area of widening is bounded by a widening surface 36. After widening, the cross-section remains constant.

Figures 4 and 5 show that the water drainage elements 55 rest on a lower roof panel 31. The support element 2 is thus supported on the lower roof panel 31 via these water drainage elements 55. Four openings 9 are arranged between the four water drainage elements 55 shown here, which allow the condensate to drain away in the flow direction F.

The flow direction F of the condensate will be discussed in more detail below.

The flow direction F shown in the figures illustrates the flow direction F of the potential condensate. Accordingly, the condensate from the second variant of the first development and the aforementioned funnel-shaped second group with water drainage elements 56, 57 and the funnel-shaped first group with water drainage elements 50, 51 is specifically drained through the opening 8 between the two groups in the flow direction F.

The water flowing from opening 8 flows in flow direction F between the water drainage elements 52, 53 of the first variant of the first further development. The condensate is guided away by the water-bearing side walls 502, 503.

The wedge-shaped structure, in particular the water-conducting side wall 504, of the water drainage element 54 of the third embodiment, which is positioned transversely to the flow direction F, directs the condensate towards the openings 7. The condensate is carried away by the Water is channeled away via surface 6. In particular, condensation is channeled away from the support element surface. The condensation runs onto the lower roof slab 31, where it continues to flow in the direction of flow F.

Furthermore, the condensation on the lower roof tile 31 flows in the direction of flow F through the four openings 9 and through the subsequent four water drainage elements 5 of the second further development. The water-bearing side walls 505 guide the water.

Figure 4 shows the mounting system 26 in its installed position. The spacer 1, according to the preferred embodiment, is mounted on the first batten 28. The bearing section 24 is in contact with the first batten 28. The lower bearing surface 3 rests on the first batten 28. The second batten 29 rests against the first batten 28. Figure 4 also shows another upper roof panel 30 and another lower roof panel 31. This second upper roof panel 30 rests on a sealing strip 35. In a subsequent assembly step, the lower roof panel 31 is placed on the sealing strip 35 and on the second batten 29.
