Abstract

The invention relates to a roof tile (1) comprising a tile surface (2) having an upper and a lower tile side, being delimited in the top view by an upper and lower wide side edge (3, 4) and a left and right longitudinal side edge (5, 6) and at least one lateral interlocking joint (7) adjacent to the tile surface (2) in the region of a longitudinal side edge (5, 6) and one depression (8) with a depth (18) in the region of the tile surface (2). The surface area of the depression (8) occupies 50% to 85% of the tile surface (2) on the upper side of the tile.

Description

tile

The invention relates to a roof tile comprising a brick surface with a Ziegeloberund brick bottom, which is delimited in plan view of an upper and lower broadside edge and a left and right longitudinal side edge, and at least one adjoining the brick surface Seitenverfalzung in the region of the longitudinal side edge and a trough with a depth in the area of the brick area.

It is always attempted to keep the production costs for a building as low as possible. Of course, this cost pressure also affects the roof surface or roof tiles. On the one hand, this can be achieved by keeping material costs low. However, this can also be achieved by reducing the costs for the use of raw materials and / or shortening the time for production. On the other hand, the period for the completion of a building should be kept as short as possible, so that a few working hours are incurred.

Despite all cost pressure, the function and especially the tightness of a roof should not be negatively influenced.

Object of the present invention is therefore to keep the cost of producing a tile low and reduce the effort required for laying the same without compromising functionality.

The object of the invention is achieved in that in the above-mentioned tiles the trough in their surface area occupies 50% to 85% of the brick area on the brick top, thereby ensuring that the water supply of the roof surface water in a defined area - namely the area of the trough - he follows. Due to the structurally simple design of the tile - especially because this has no Kopfverfalzung - is further allows that they can be installed on a simple to produce, structurally complex roof battens and thereby material, wood and labor of the roofer can be saved. Also for roof renovations of the roof tiles according to the invention is very well suited, because due to the lack of Kopfverfalzung no change in roof battens compared to many standard roof tiles must be made. By the large trough, it is possible to form the tiles with only a simple Seiten- fold, which in turn simplifies the production of the tile and thus is less expensive. The large trough can also increase the storm resistance of the tile by pressing the roof tile over this trough and the wind pressure against the roof battens.

Furthermore, it is provided that in the region of the upper broad side edge, a cover area which is raised in relation to the trough is formed, whereby no head seam which is expensive to produce is required. It also makes it possible for neighboring roof tiles to be positioned in the direction of the roof slope through the covering area. It is also advantageous that the roof tiles are displaceable along their longitudinal extension and thereby the overlap length of two adjacent roof tiles can be made very variable.

It is also advantageous that the depression in the direction of the left and right longitudinal side edges is bounded in each case by an elevation which is at least approximately flat, in particular flat, whereby the removal of water in the latter takes place through the elevations in a defined region.

The trough may be formed in its longitudinal extent at least approximately parallel to the left and right longitudinal side edge, whereby a simple, fully automated and thus cost-effective production of the roof tile according to the invention is made possible.

Furthermore, it is provided to arrange the trough at least approximately symmetrically to a longitudinal central axis, which is centered to the right longitudinal side edge of the tile surface and an outer longitudinal side edge of the Seitenverfalzung, whereby the laying of roof tiles can be done in a simple manner. In addition, this also positively influences the appearance of the covered roof.

The trough can be greater in its longitudinal extent than a half tiled length in the direction of the longitudinal central axis from the lower to the upper broad side edge, which ensures that the water flow and thus the outflow of the water is not delayed even in heavy rainfall. It is thus also achievable that, when the roof is finished, the covering area of two roof tiles arranged one above the other is reduced to the level of the trough. rich, so that essentially creates a "continuous" trough from the ridge to the gutter.

It is further provided that the at least one Seitenverfalzung at least one, parallel to the left longitudinal side edge extending longitudinal ridge comprises, whereby a positioning is facilitated to an adjacent tile in the direction transverse to the roof pitch.

The at least one side fold has a groove-like depression with a depth in a transition area to the tile surface, thereby preventing water which possibly enters the gap between two adjacent tiles from being diverted from the depression.

In a further development, the at least one Seitenverfalzung have at least one further longitudinal ridge, wherein between each adjacent longitudinal webs in transition area at least one further recess is formed, whereby the exact positioning of adjacent roof tiles facilitates and the tightness of the roof is improved.

Furthermore, it can be provided that the depth of the first recess is at least approximately the same size as the depth of the trough can be, whereby water which exits from the trough, is discharged through the recess.

The depth of the further recess may be less than the depth of the first recess, thereby providing a positioning aid, as already mentioned.

The fact that a Seitenverfalzungslänge the Seitenverfalzung extends at least approximately over a total length of the tile in its longitudinal extent, allows the roof tile over a wide range is displaced and thus the coverage area of two roof tiles can be made very large. In addition, it can be dispensed with costly pressing process for the production of the tile.

By means of breakthroughs, in particular in the area of the brick surface, the roof tiles can be connected, for example, with nails with the battens and thus obtain a better grip on the roof surface. The tile according to the invention can be produced in particular by an extrusion process, whereby a very cost-effective mass production is made possible.

At least one corner in a transition region from the upper broad side edge to the right or left longitudinal edge or Seitenverfalzung may be rounded or beveled, whereby deformations, such as buckling or distortion of the tile, during the manufacturing process and during use of the tile at least largely can be prevented ,

The surface of the tile surface may be approximately smooth, allowing for easy surface treatment and also achieving a modern and user-friendly design.

In a further development, it is provided to limit the trough in the region of the lower broad side edge with at least one at least approximately web-like elevation, which has at least one breakthrough, whereby the retention capacity for snow is increased and a safety measure against the slipping of snow is achieved.

The at least approximately web-like elevation can be formed by at least two mutually conical or extending in a round part webs, whereby the discharge of water is facilitated with constant slip resistance for snow.

The invention will be explained in more detail below with reference to the simplified and schematically illustrated in the drawings embodiments.
