In the in FIG. 1 Roof tiles 1 are arranged as roofing elements in rows R and columns S on a roof substructure 2. The roof substructure 2 consists of rafters 2s, which extend inclined from the ridge to the eaves, and horizontally lying transversely to the rafters 2s battens 2t. These battens 2t are mounted transversely on top of the rafters. On the battens 2t the roof tiles 1 on the underside hanging noses 1 n, as in the FIGS. 2a and 2 B shown, hung.

In the figures, the roof tiles in adjacent columns S are each denoted by 1 and 1 'for a better understanding of the spatial arrangement. However, the roof tiles 1, 1 'are identically formed roof tiles.

How best in FIG. 1 can be seen, the rows R and columns S of the roof tiles are mutually perpendicular, ie, the rows R horizontally and the columns S along the roof pitch from ridge to eaves. The roof tiles in the rows R and the roof tiles in the columns S overlap each other by the adjacent in the rows R roof tiles 1, 1 ', 1, 1' each overlap each other laterally and arranged in the columns S adjacent roof tiles 1, 1st or 1 ', 1' overlap such that in each case the eaves-side end of the first side arranged Roof tile 1 ', 1' overlaps the ridge-side end of eaves side adjacent roof tile 1 ', 1'. There are thus overlapping areas each in the overlapping brick corner areas, which in the in FIG. 1 illustrated embodiment of the roofing are designed as Vierziegeleck 1a. In the areas adjacent to the four-tile corner 1a in the same horizontal row, the overlap is only a two-square overlap. In these two-seal overlapping regions 1 b, in the exemplary embodiment, the roof covering in FIG FIG. 1 Equally distributed over the roof covering in each case two-mirror overlapping regions 1 b equipped with a securing device 5.

The securing device 5 is a device by means of which the roof tiles 1, 1 overlapping in the area 1b are fixed to the roof substructure 2 via a securing element in order to prevent the roof tiles from being lifted off, e.g. As in the case of storm, secure.

In the embodiment in the FIGS. 2a . 2 B and 2c For example, the securing device 5 has a securing element 25, which is designed as a curved sheet-metal part. This securing element 25 is in the FIGS. 3a and 3b shown in single representation. In the FIGS. 2a . 2 B and 2c the fuse element 25 is shown in its installed position in the roofing. The formed as a bent sheet metal part securing element 25 is formed in its lower portion as a fixing portion 25f and screwed by a screw with the supporting bar 2t. At the upper free end, the sheet metal part 25 has a cranked end, which is formed as a clamping portion 25k. In the roof covering, this clamping section 25k engages in a clamping receptacle which overlaps on the underside of the upper one Tile 1 is formed. This upper roof tile 1 is in the representation of the roofing in FIG. 2a removed for clarity.

The clamping portion 25k of the securing element 25 is in the concrete embodiment in FIG. 2 formed as an acute-angled edged or round angled end of the sheet metal part. In the connecting portion 25v, which extends between the upper clamping portion 25k and the lower fixing portion 25f, the sheet metal part is bent about its longitudinal axis by 90 °, so that the fixing portion 25f rests on the ridge-side side surface of the support slat 2t and on in the Support batten 2t engaging fixing screw, which passes through a hole in the fixing portion 25f is attached. The formed at the upper end clamping portion 25k is thereby rotated by 90 ° relative to the Fixierungsabschnit 25f, so that the ridge edge of the angled clamping portion 25k along the ridge-eaves line is arranged and in a corresponding terminal receptacle on the underside of the tile 1 complementary under bias under Training a clamp attachment engages. The connecting portion 25v extends in the same plane as the ridge edge of the clamping portion 25k, that is rotated in the same way by 90 ° relative to the fixing portion 25f and engages the cross-roof tile 1 laterally over.

As in the FIGS. 2a . 2 B and 2c it can be seen, the securing element 25 fixed to the supporting bar 2t is oriented vertically upwards. It is arranged with its connecting portion 25v passing by on a side edge of the eaves-side roof tile 1. The upper as a clamping portion 25k angled free end is above the top of this tile 1 addition to in the in FIG. 2a not shown overlapping, in the relevant column S ridge adjacent roof tile 1 intervene, in a formed on the bottom of the eaves-side end portion of this tile 1 terminal receptacle.

In Figure 2c it can be seen that the roof tiles 1, 1 'each have a ridge-side corner cutout 1e. The corner cutout 1 is open on the edge and, in the case shown, is designed with a rectangular floor plan surface. Secured to the roof batten 2t securing element 25 passes through its connecting portion 25v the corner cutout 1e of the underarching roof tile 1 and engages over this with its clamping portion 25k to engage in the clamping receptacle on the underside of the not shown ridge cross-roof tile 1, not shown. The connecting portion 25v at the front edge of the corner section 1e with a small distance or immediately touching over. In the case shown in FIG Figure 2c The connecting portion 25v extends at the lateral end edge of the corner cutout 1e near the corner region.

A significant advantage of the present invention is that the securing element 25 is formed passing on the cross-roof tile 1 passing. There is no penetration through this tile 1, ie a through hole in the tile is not required. A peculiarity of the specific embodiment of the securing element 25 is that the securing element 25 is not supported on the upper side of the underarching roof tile, but exclusively with the fixing section 25f is fixed to the support bar 2t via the screw connection and engages with the free upper clamping section 25k on the underside of the overlapping tile under clamping engagement.

In the in the FIGS. 4a and 4b illustrated modified embodiment, the securing element is designed as a wire member 35. Its installation position in the roofing is in FIG. 5 shown. As can be seen from the figures, the wire member 35 also at its lower end to a fixing portion 35f, with which the wire member 35 is fixed to the supporting bar 2t. The fixing takes place in the illustrated case also by a screwed into the rafters 2s laterally fastening screw. The fixing portion 35f is formed in this area as an eyelet into which the fastening screw for fixing the wire member 35 engages. At its free upper end, the wire member 35 is also formed as an angled or rounded clamping portion 35k. In the installed position, the wire component 35 fixed to the rafters 2s is the same as the securing element 25 in FIG FIG. 2 in its fixation position substantially vertically aligned. The wire member 35 also engages the under-reach tile 1 over; However, it has in its vertical connecting portion 35v on a right angle projecting support portion 35l, which rests horizontally rests on the top of the cross-roof tile 1. The support is formed on the top of the edge region of the tile. By this edition of the support portion 35l on the top of the lower tile 1 of the cross-roof tile is held specifically by the securing element 35 through the support portion 35l. The overarching roof tile is held by the securing element 35 in that the clamping portion 35 k in one at the bottom of the overlapping roof tile engages trained clamping receptacle. The securing of the overlapping tiles is thus carried out with the fuse element 35 of FIGS. 4a and 4b in the same way as with the securing element 25 of the FIGS. 3a and 3b However, in the execution of the FIGS. 4a and 4b In addition, the lower roof tile 1 is held separately by the securing element 35 via the support section 35l.

As for the arrangement of the fuse element 35 in the installation position in the roofing, be on FIG. 5 directed. The representation in FIG. 5 corresponds to the illustration in Figure 2c , The only difference compared Figure 2c is that in FIG. 5 instead of the securing element 25, the securing element 35 is inserted. As can be seen, the securing element 35 is fastened in a corresponding manner to the roof batten 2t and, with its connecting section 35v, engages on the underarchive roof tile 1 at an end edge of its corner section 1e. However, it is essential for the securing element 35 that the support section 35l rests on the upper side of this undercut roof tile 1, so that this roof tile is fixed separately. The clamping portion 35k projects beyond this underarchive roof tile 1 for clamping engagement in the clamping receptacle on the underside of the overlapping roof tile 1 adjoining the first side.

It should be noted that in modified embodiments of the securing element 25 or 35 of the fixing portions 25f and 35f may be formed so that the attachment to the roof substructure 2, ie preferably on the roof batten 2t without tools or with a very simple tool can be done. The fixation section can for this purpose z. B. as a batten at least partially encompassing section z. B. be designed as elastically resilient gripping end. Alternatively, the fixing portion may also be formed as a pointed nail-like impact end or as a wood screw end, ie for easy insertion or screwing of the fuse element.
