In the Figures 1 and 2nd a first embodiment of a roof covering element 1 according to the invention is shown. The roof covering element 1 has a ridge-side head section 10 and a eaves-side foot section 20 opposite the head section 10, as well as a side water fold area 30 and a side cover fold area 40. A central field 50 is formed between the two side fold areas, the head section 10 and the foot section 20.

The Figures 1 show a top view ( Figure 10 ), a front view ( Figure 1b ), a side view ( Figure 1c ) and a detailed view ( Figure 1d ), which a portion of the roofing element 1 of the Figure 1b represents enlarged. The Figures 2 show spatial representations of the first embodiment of the roofing element 1 according to the invention from the Figures 1 from above ( Figure 2a ) and from below ( Figure 2b ), as well as an enlarged detailed view ( Figure 2c ) a part of the head region 10 from the Figure 2b .

The head region 10 has, as in FIGS Figures 1 and 2nd shown, a fastening portion 11 on the head section side, which has a projecting section 12 on the roof covering element side and a receiving section 13 on the roof covering element side. The projecting section 12 on the roof covering element side is shown in FIGS Figures 1 and 2nd formed as a nose protruding in the planar extent of the roofing element. The roof covering element-side receiving section 13 is as in FIGS Figures 1 and 2nd formed as a groove. On the roofing element 1 in the Figures 1 and 2nd four projecting sections 12 and four receiving sections 13 are formed. The roof covering element 1 has a plurality of support webs 2 on the underside, which in the embodiment of the Figures 1 and 2nd are tapered. As in the Figures 2b and 2c shown, the projecting section 12 and the receiving section 13 is formed in the region of the support web 2 on the underside of the roof covering element 1. The projecting section 12 can be formed by sawing or milling the blank or the fired blank. It is also possible to arrange the projecting section 12 by an additional component on the roof covering element 1, for example by screwing. The receiving section 13 is formed by sawing or milling the blank or the fired blank.

As shown in FIGS Figures 1 and 2nd shown, a foot portion side mounting area 21. This is formed by two grooves 22 in the area of the support webs 2. The grooves 22 can be formed over the entire length of the roof covering element 1 from the foot region 20 to the head region 10. This makes it possible, if necessary, to shorten the roof covering element 1 in the foot region 20, wherein due to the grooves 22 formed over the entire length, there is still the possibility of fastening in the foot region 20.

The side water fold area 30 faces as in FIGS Figures 1 and 2nd shown, a water rebate groove 31 and a water rebate web 32, which extend laterally from the head region 10 to the foot region 20 over the entire length of the roof covering element 1. It is also possible to form a plurality of water rebate grooves 31 and one or more water rebate webs 32 in order to increase the rain resistance of the roof covering element 1.

The side cover fold region 40 has, as in FIGS Figures 1 and 2nd shown a top rebate groove 41 and a top rebate web 42, which extend laterally from the head region 10 to the foot region 20 over the entire length of the roof covering element 1. It is also possible to form a plurality of cover seam grooves 41 with one or more cover seam webs 42 in order to increase the rain resistance of the roof covering element 1.

The side rebate areas 20 and 30 are formed such that, in the state laid as a roof covering 80, in the case of adjacent roof covering elements 1, the side cover rebate area 40, which is formed on the underside of the roof covering element 1, has the side water rebate area 30, which is located on the top of the Roof covering element 1 is formed, overlaps.

The roofing element 1 has, as in the Figures 1 and 2nd shown, a jagged structure with serrated valleys 3 and serrated mountains 4. These depressions 3 and surveys 4 are over the entire Roof covering element 1 in the middle field 50 is periodically recurring and determines both the design on the top of the roof covering element 1 and on the underside of the roof covering element 1. The jagged structure is repeated periodically. Due to the serrated structure and its recesses 3 on the top of the roofing element 1, the support webs 2 are formed on the underside of the roofing element 1 to a tapered support surface 5. The support webs 2 are in the Figures 1 and 2nd complementary to the structure of the midfield 50 is formed. The roof covering element 1 thus has the same material thickness over its entire width. This is advantageous because it enables uniform drying of the blank.

The jag-like structure of the roofing element 1 can be achieved by forming the roofing element 1 in an extrusion process. The extrusion direction extends from the head region 10 in the direction of the foot region 20. As a result, the support webs 2 are formed in one piece in the roof covering element 1 by the extrusion process. It is also possible to process the support webs 2 by the extrusion process in order to preferably have a flat support surface 5 (in the Figures 1 and 2nd not shown). Furthermore, the water rebate groove 31, the water rebate web 32, the cover rebate groove 41 and the cover rebate web 42 are formed in the course of the extrusion process. It is also possible to form the grooves and webs by reworking the blank or the fired blank.

In the Figures 3 two roof covering elements 1 as well as a first fastening element 60 and a second fastening element 70 are shown.

The roof covering elements 1 are arranged together as a roof covering 80, the foot section 20 of the upper roof covering element 1 resting here on the head section 10 of the lower roof covering element 1.

As in the Figures 3 shown, the first fastening element 60 is designed as a load-bearing profile element and serves as a weight support or as a weight support and locking bearing for the roof covering elements 1. The first fastening element 60, hereinafter referred to as profile element 60, has a base body, a projecting section 61 and a receiving portion 62. The basic body in the Figures 3 consists of a rectangular hollow section with a cross section and the receiving section 62, which is reinforced by means of a strut. The projecting section 61 is formed on the upper side of the rectangular hollow section. It is also possible for the profile element 60 to have only a rectangular hollow profile as the base body, in which case both the projecting section 61 and the receiving section 62 are arranged on its upper side (see Figures 4 and 5 ). The two sections 61 and 62 are in the embodiment of FIG Figures 3 formed over the entire length of the profile element 60, but can preferably also be formed only in sections. The projecting portion 61 is shown in FIGS Figures 3 formed as a nose extending in the direction of the roof covering element 1. The receiving section 62 is designed as a groove.

Like in the Figure 3a illustrated, the profile element 60 interacts with the fastening section 11 of the roof covering element 1 on the head section side, the projecting section 12 of the roof covering element 1 engages in the receiving section 62 of the profile element 60. The projecting section 61 of the profile element 60 engages in the receiving section 13 of the roof covering element 1. The respective projecting sections are complementary to the respective corresponding receiving section in order to enable the engagement.

As in the Figures 3 shown, the second fastening element 70 is designed as a locking connecting element 70, which serves to fasten the roof covering element 1. The second fastening element 70, which is referred to below as the connecting element 70, has a fastening section 71 for fastening to the roof covering element 1, and an anchoring section 72 for engagement with a load-bearing profile element 60. The connecting element 70 is viewed from the front a V-shaped body on and viewed from the side an L-shaped body. Two arcuate brackets are formed in the fastening section 71.

Like in the Figure 3a illustrated, the connecting element 70 interacts with its fastening section 71 with the fastening section 21 of the roof covering element 1 on the foot section side. The arc-shaped holders in the fastening section 71 engage in the grooves 22 on the underside of the roof covering element 1. Due to the V-shaped design of the connecting element 70, the arc-shaped holders snap into the grooves 22. Furthermore, the connecting element 70 cooperates with its anchoring section 72 with the profile element 70, on which a further roof covering element 1 adjoining the roof covering element 1 is supported. To do this, the Anchoring section 72 the profile element 60 and thereby prevents lifting of the foot region 20 of the roof covering element 1. With its anchoring section 72, the connecting element 70 can also engage and / or engage the load-bearing profile element 60 on which the roof covering element 1 is supported on a load-bearing profile element 60 on which a further roof covering element 1 adjoining the roof covering element 1 is supported, and / or on a roof substructure on which the supporting profile element is supported.

Figure 4 shows a roof covering 80 from below with a plurality of roof covering elements 1 which, as described above, are arranged one above the other and rest on the load-bearing profile element 60. The roof covering elements 1 are arranged on a roof substructure in horizontal rows and columns perpendicular thereto so that adjacent roof covering elements 1 in a row and / or adjacent roof covering elements 1 in a column overlap one another, with an upper roof covering element 1 with its foot section 20 on the head section in the columns 30 of a lower roof covering element 1 is arranged. The roof covering elements 1 are mounted on the roof substructure, wherein the roof covering elements 1 are mounted on the roof substructure through the fastening section 11 on the head section side with the profile element 60, and the roof covering elements 1 are mounted on the roof substructure through the fastening section 21 on the foot section side with the connecting element 70 . The connecting element 70 of each upper roof covering element 1 engages under the profile element 60 of the lower roof covering element, or a part of the roof substructure, for fastening the upper roof covering element. The connecting elements 70 engage under the profile element 60 or Roof substructure, and secure the roofing elements 1 against lifting.
