Definitions

• the invention relates to a roof tile with a water rebate on one longitudinal edge and a cover rebate on the opposite longitudinal edge, the water rebate and the cover rebate extending over the entire length from the head-side edge to the foot-side edge and longitudinal longitudinal bottom ribs or upper longitudinal ribs and in Area of the foot-side edge of longitudinal ribs have free areas that form a flat parting line when two roof tiles are covered next to each other.
• Similar roof tiles in which the longitudinal ribs extend over the entire length of the tile, are known, for example, from DE-C 42 34 181 and generally from roof tiles produced by the extrusion process.
• these roof tiles can be moved lengthwise towards the ridge without having to be lifted.
• tread holes are created for the roofer by pushing up individual roof tiles by about half their length towards the ridge. This can then appear on the head of the exposed roof tile, with the load being introduced into the roof substructure over a short distance without a roof tile being subjected to bending.
• the lateral ribs of the folds of such a roof tile have play in the transverse direction, so that the roof tiles can be "stretched” or “pressed” in the transverse direction in order to allow the width of the covered area to be adapted to the width of the roof substructure.
• the transverse displaceability of two roof tiles laid side by side can be up to one centimeter.
• openings occur in the area of the folds at the foot-side edge, the cross-section of which corresponds to the height of the ribs, corresponds to the number of ribs and the degree of transverse displacement. For example, with a height of the longitudinal ribs of 8 mm, a transverse displaceability of 6 mm and two longitudinal ribs in the water fold and in the cover fold, an opening cross section of around 100 mm 2 remains free.
• Openings can cause drifting snow or drifting rain, and insects can also enter.
• Such openings have long been avoided in interlocking tiles in that the foot-side end section of the cover rebate is pulled down to the surface of the adjacent roof tile covered in the eaves direction.
• a roof tile is described for example in DE-U 295 04 404.7.
• these roof tiles have a recess at the foot-side end of the water rebate.
• the water rebate does not extend over the entire length of the roof tile.
• a roof tile designed in this way cannot be displaced in the longitudinal direction without being raised so high until the foot-side end section of the cover rebate can be pushed over the water rebate. This creates tension that can cause this and an adjacent tile to break.
• roof tiles are known from EP-A 0 284 350 which contain at least two tile elements which lie in different planes and have a water fold with a lower longitudinal rib on one longitudinal edge and a cover fold with an upper longitudinal rib on the other longitudinal edge, in the area of the foot side Free areas are provided at the edge of the longitudinal ribs, which form a flat parting line when two roof tiles are covered next to one another.
• the area free of the longitudinal rib lies in the base plane of the water fold, while in the area of the cover fold the area free of the longitudinal rib lies at the height of the
• the object of the present invention is to provide a longitudinally displaceable roof tile of the type described at the outset, which is designed such that it can be used to produce a step hole for the roofer without
• Lifting can be moved towards the ridge without affecting the position of the surrounding cover.
• the object is achieved in that the areas in the area of the foot-side edge of longitudinal ribs are designed as areas which are elevated relative to the base plane of the water rebate or the base level of the cover rebate, so that when two roof tiles are covered next to one another, the increased area of the cover rebate is on the raised one Area of the water fold can rest, and that the longitudinal ribs are flattened towards the raised areas, so that the longitudinal ribs gradually reach their full height.
• the raised area of the cover rebate slides on the ribs of the water rebate of the adjacent roof tile on the one long side and the raised area of the water rebate slides under the ribs of the roof rebate of the adjacent roof tile on the other long side.
• the height of the raised regions advantageously corresponds to approximately half the height of the longitudinal ribs.
• Moving the roof tile in the longitudinal direction is facilitated because the longitudinal ribs are flattened towards the raised areas so that the longitudinal ribs gradually reach their full height.
• lifting before moving is not necessary because, as a result of sliding on the inclined planes of the end sections of the ribs, a slight lifting takes place automatically when moving.
• the displaced roof tile is raised less due to the raised areas having half the height of the longitudinal ribs.
• Water that has penetrated into the water rebate is safely drained off to the side if at least the front side of the raised area of the water rebate, which faces the head-side edge, runs obliquely to the foot-side edge, and if at least the lower longitudinal ribs of the water rebate adjacent to this front side have an interruption.
• the raised area of the water fold preferably has an approximately trapezoidal or triangular base area.
• the end face of the raised area of the water rebate facing the head edge advantageously runs obliquely towards the longitudinal edge, so that the water running off is drained off to the adjacent roof tile.
• the front side of the raised area of the water rebate facing the head edge should run obliquely towards the watercourse so that the water is drained into the water course of the same roof tile.
• the raised area of the cover fold can directly adjoin the upper longitudinal ribs and have a rectangular base area. If a strong accumulation of water in the water fold is to be expected, the upper longitudinal ribs of the cover fold can of course be interrupted in front of the raised area, so that a large cross section is available for draining off the water. In this case, the base area of the raised area of the cover fold can be congruent with the base area of the raised area of the water fold.
• the base plane of the water rebate can be inclined in the transverse direction of the roof tile towards the watercourse so that water which has penetrated is discharged laterally into the watercourse. As a result, the water is drained not only when the elevated area is reached, but also beforehand.
• a profiled roof tile such as a hollow rebate tile closes particularly tightly to an adjacent roof tile covered in a row on the eaves side if the roof tile on its underside has at least one transverse rib on its foot-side edge, the contour of which on its underside corresponds to the contour of the top of the roof tile corresponds. It is advantageous in the area of the foot side
• the effect of the labyrinth is increased if the roof tile has at least one, better several, grooves running in the transverse direction on its upper side in the region of its head-side edge.
• the grooves preferably extend at least from the water seam to approximately the apex of the bead. The penetration of water from the watercourse at the head-side edge is prevented even in strong winds if the roof tile has a top rib running in the transverse direction at its head-side edge at least in the region of the watercourse. This represents a barrier.
