EP1799932B1 - Device for fixing dry-laid ridge tiles - Google Patents

Abstract

Dry laying ridge tiles etc. have considerable advantages in relation to aeration and in the region of laying and durability. The ridge tiles are very exposed therefor they must be maintained towards the base in relation to the force of the wind. The work of the roofer must be made as simple as possible. Despite the simplicity thereof, the ridge tiles or similar must be maintained with at least the necessary force over a number of years. The aim of said device is achieved by virtue of the fact that the approximately horizontal, lower part of the clamping device, in the symmetrical line area (crown area), has a hole which has a slot in the region of the edge, which comprises a blocking-clawing device for the securing wire.

Description

The invention relates to a device according to the preamble of the main claim.

Until relatively recently, ridge tiles, after being laid on the ridge, were placed in a mortar bed at their longitudinal edges, which run horizontally and parallel to the battens, and also through the bed of mortar on both sides facing snow and ice, rain, storm, etc . sealed after the mortar had set.

Even today, this type of installation is often used. The mortar is unreliable in many ways, especially as a roof can have a life expectancy of one hundred years. The mortar bed must be renewed, repaired and otherwise used during this period several times.

In the course of time, therefore, dry laying of the ridge tiles was achieved. These have arcuate shape in cross section. In dry laying, however, it is necessary, just as in laying in the mortar bed, to pull down the ridge tiles with a force of about 0.6 kN / m without relying on the holding force of the mortar joints or the like.

Each type of ridge tile has different geometrical shapes, because it has to match the roof tiles. Since then, the problem has been solved by optionally providing a shallow recess in the overlapping area of the ridge tiles in the very upper outer area, which optionally has the curved gutters have left in their cross section. The element holding the ridge tiles was a stepped bent aluminum sheet metal strip having several 90 ° bends. In order to fasten this metal strip at the time, ridge battening has been provided in addition to the two top battens. This additional ridge batten was between the two top battens with their elongated rectangular cross-section. The top of this ridge batten has then offered a contact surface for the bottom staircase of the metal strip. Since the bottom step has two through holes, the roof ridge was fixed with two wooden screws. For this purpose, the roofer had to carry an electric battery powered Schraubwerkzeug device. In the lining of the cordless screwdriver stuck a screw bit, matching the head of the wood screw. It has then screwed the lowest level of the sheet metal angle on the top of the roof batten.

Now, if the top of the ridge batten had the right clear distance to the end of the respective ridge tile, then with the necessary downward pulling force, this angle with the undersurface of its uppermost horizontal step has biased the ridge tile downwards. In addition, it has then pushed into the upper, approximately U-shaped bracket, the end portion of the roof tile covering the second ridge tile in, so that even this was held with the necessary clamping force.

It required a lot of conditions so that the downward force could be generated reliably and in mass operation.

All this has been accepted, although the number of ridge tiles to be laid is high in the millions. Despite this expense, the dry laying of ridge tiles displaced more and more laying in the mortar bed.

A disadvantage of this solution, the additional ridge batten, which must be raised, must fit in their height and must be mentioned in the tender. Furthermore, a cordless screwdriver can slip from the hands of the roofer. The screw bit may fall out. The wood screws can be lost. It is despite It is also possible that the downward force is too small, which is worse than if it were too big.

If the upper side of the ridge batten is too close to the ridge tile, you have to plan the top side with a planer.

The commonly used ridge brackets are made of aluminum and coated on both sides with paint, so that they fit into the aesthetics.

From the DE 32 17 645 A1 For example, an apparatus for fixing bricks is known, which has a metal strip with a U-shaped socket for receiving an end edge region of a brick and a continuation strip which is bent in the manner of a side fold clamp / storm clamp.

The DE 43 07 982 A1 teaches a device with a U-shaped socket having in its lower leg an opening which is traversed by a wire.

Furthermore, it is common for a roofer to apply storm braces, e.g. Made of Zial (zinc aluminum), in order to secure the roof tiles during storms. Such a storm clip has on its inside to use side bends similar to a U with an integrally formed on the free end Aufgleitflanke.

At the other end a hook is provided with which one usually engages in a tile collapse. Hooked to a roof batten inside the roof, the hook in the end area of the storm clip pulls the storm clip down. Both components have long been part of the fastening material to deal with the roofer.

The object of the invention is to provide a device that does not require a screw fastening, with the associated advantages, without being able to work with a related tool on the roof ridge.

As little as possible of the well-known technique should be changed, so that familiar objects can continue to be used.

A very significant advantage of the invention is also that, for example, Dachsanierungen, preferably old roofs, from the mortar laying the ridge tiles can be easily switched to the fan-edge technology. This is because now ridge plates are no longer necessary, which should have been provided after covering the ridge tiles so far to keep the ridge tiles down. In many cases, this may even be cheaper than using the old mortar bed technique.

This object is achieved by a device for fixing ridge tiles by means of a metal strip whose end portion has a U-shaped socket for a front edge region of a ridge tile and the U-shaped socket has an opening in its lower U-leg and the head of a wire the opening traversed, solved, wherein the head of the wire rests after a kink with the kink area on a top portion of the lower U-leg and the wire after the kink has a length according to the Firstziegeldicke and after this length a wire, bent according to a storm clip, connects ,

Furthermore, the invention provides that the ridge tile has a through hole, which is provided in the cover region of the ridge tile / ridge tile and / or U-shaped socket.

In another variant, the opening is a bounded hole.

Also, the opening may be a slot that has a distance with its edge facing the cross bar, wherein the kink area rests on the appropriate area.

In a further variant, the kink area is a pillows head, a piece of wire, a hook area or the like.

The invention will now be described with reference to a preferred embodiment. In the drawing show:

In the embodiment according to the invention, the ridge tile 51 has a vertical through-hole 52 in its left-hand covered area. This is smaller in the passage than those through-holes through which a threaded screw shaft can be inserted. A smaller through hole, which receives a round wire or a flat wire, is naturally also liquid-tight.

The region 53 of the ridge tile 54 to be held down, which overlaps the left region of the ridge tile 51, is caught in its overlapping part of the region 53 by a shortened ridge clip 57. With its two upper fingers 58, 59 it engages over the top of the area 53 (upper leg). The crosspiece 61 is located in front of the right-facing end face of the ridge tile 54. After a 90 ° bend 62, the lower leg 63 is located between the region 53 and the upper side of the ridge tile 51 there FIG. 2 As can be seen, the ridge bracket 57 has a shape that causes spring properties. The lower leg 63 extends beyond the left end face of the ridge tile 51 addition.

The lower leg 63 has a slot 64, which allows for tolerances in the positioning in the longitudinal direction. The slot 64 is narrow, but with its one end bow 66 is far from the kink 62, so that on the top of the leg 63 a downwardly non-deforming elbow (or kink area) 67 can bear resiliently. This elbow 67 thus lies between the leg 63 and the underside of the ridge tile 54. As you can see, the slot 64 can accommodate the length tolerances. In addition, you can see between the two fingers 58, 59 through the slot 64th

Vertically down now passes through a round wire / flat wire through hole 52. After lying below the underside of the ridge tile kink 68 extends in a length of 10 to 15 cm of the round wire / flat wire to the roof batten 69 and is hooked there in a known manner.

Thus, mounting techniques known per se are also used here. The shortened ridge clamp 57 thus does not need to be bent down. An elevation is not necessary. Even older roofs can thus be covered later as fan roof tile roofs.

If in the above "bricks" was mentioned, so are all other equivalent components meant as for example ridge stones, end plates, etc. In ridge stones even has the advantage that they always and from the outset have a through hole analogous to the through hole 52.
