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

Device for fixing dry laid roof tiles and ridge stones

The use relates to a device for fixing dry laid ridge tiles, ridge stones or the like with approximately arcuate cross-section in the ridge region of a roof.

Such dry laid ridge tiles / bricks must be held on the roof. So far, special designs have been developed that have ridge tiles / bricks held by storm clip-like wireforms. The state of the art can be found, for example, in the "Encyclopaedia of Bricks" by Willi Bender, Bauerverlag GmbH On page 64, the state of the art can be found and described under the heading "ridge-fan brick". In the prior art, special ridge brackets are fastened on the one hand to the horizontal, uppermost purlin of the roof scaffolding and, on the other hand, to a fold of the ridge tile or ridge tile. The ridge tiles have, according to page 65 in part, an excessive rebate, in part a hidden seam or go smoothly without folding into each other. The ridge tile shapes are very diverse, such as straight, oblique, oblique with nose, saddle-shaped, profiled etc. Dry laying of ridge tiles has many advantages, such as: B. the mortarless laying. As a result, it is not necessary to design a mortar bed. The ridge is practically always the highest area of a building with the resulting dangers, the poor accessibility in later time, etc. The dry laid ridge tiles / stones promote ventilation, prevent mold growth in the ridge area or the like. However, they must be pulled down according to the building regulations with an unrivaled force. For this purpose, one uses special traction elements, on the one hand in the coverage area pull down a tile and maintain this tension only if the distance between the top of the purlin and the point in the overlap area at the ridge tile according to the lengths of the tensile materials used. If this distance is not very accurate, then the train can become much too small, especially over time, and the ridge tile / stone no longer hold properly. This can not be seen from the outside, because you do not see the train, under what tension he is. To ensure that these clearance conditions are met, it is often necessary to plan the top of the purlin to size, which requires a great deal of effort.

But even if you use only part lengths of a purlin and aufständert this on a piece of wood, you have to do the necessary work.

So you need a lot of tools that can bring dangers and completion time loss with it.

If you do without the use of a ridge purlin or partial lengths of ridge purlins and storm clip-like wireforms, then you do not need a ridge purlin or the like, but you can then attach one end of the wireform to a rafter. However, it still requires means for zugspannungsmäßig sufficient holding down these Ridge elements. You could now use screws here or bend the wire of the storm clip, so that the bent areas can not be bent back, etc. But it is also not this first-time technology, because you still need tools or the like and above all very experienced Roofers, who also have the power in their fingers, wire-like over long periods of time Turn over the traction device. Because: if the resistance is small, then the kink bends immediately back again.

The object of the invention is therefore to provide a much better device with which you can easily achieve that the once applied tension is maintained even in wind and weather, the ridge tiles / bricks in a simple way even stronger and more durable pulls down and despite simple construction has no significant expense in terms of accuracy, stress on the roofer and is also very satisfactory in the aesthetic sense.

According to the invention, this object is achieved by the apparent from the indicated part of the main claim features.

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

Fig. 1, the scale side view of a clip, however, in perspective

1, wherein the clip is almost in line with the through hole in the edge region of the fold of a subsequent, to be described, custom ridge tile, but the steel wire is not yet threaded, pulled through and jammed.

Fig. 3 is a substantially enlarged view of the under cross

Edge pushed clip with solid and fixed steel wire.

Fig. 4 is a similar view as Fig. 3, but from top right perspective view into the ridge area and course of the steel wire.

Fig. 5 is a Trockenfirstziegel, on the manner described in the clip has been postponed, including outstanding right up Steel wire, which is then pulled through a hole in the fold of the brick upwards and then through the recess in the longer, middle leg and then pulled by the roofer in the shown ways forward, is still bent in the through hole and by laying the edges of the hole is clamped. The figure also shows how the top leg rests on a nose of the same fan ridge tile. From this figure one also sees that the design is very aesthetic and can basically be left that way.

A preferred embodiment will now be described in detail.

A bracket 11 from everywhere the same thickness stainless steel is drawn in the mounting direction. It was manufactured with simple punching and bending devices. The stainless steel strip 12 is the same width, so has parallel edges 13, 14 which are perpendicular to the plane of the stainless steel strip 12. The bracket 11 has a lower leg 16 which is bent in its left end portion down to a short Aufgleitlippe 17, which has no interruption in the longitudinal direction, d. H. the entire width of the stainless steel strip 12 occupies. The short lower leg passes after a 90 ° - development 18, which is bent upward in a quarter circle in a short, vertical front leg 19. This is flat and passes at its upper end in a second 90 ° -Abwinklung 21, which merges into a long leg 22 and because of the two times 90 ° -Abwicklungen 18, 21 runs to the left. Since the sum of the two 90 ° windings 18, 21 are less than 180 °, the lower leg 16 extends a little towards the long, upper leg 22, so that a clamping space 23 is formed above the lower leg 16.

In the long leg 22, a through hole is punched in the middle, which merges into a longitudinal slot 26 to the right. This longitudinal slot extends in accordance with the vertical, geometric center plane of the long leg 22, communicates with the otherwise circular through hole 24 and has at its two longitudinal edges upwardly curved, sharp-edged cutting edges, which are significantly less dependent on each other than the transverse dimension of the through hole 24 corresponds , The two cutting edges 27, 28 have a smaller distance from each other than the through hole 24 is wide. Seen in the projection from above, the slot end 29 does not extend to the Aufgleitlippe 17, but ends in front of it. The cutting edges 27, 28 are bent outwardly higher in the area adjacent to the through-hole 24 than in the vicinity of the slot end 29. The cutting edges 27, 28 are closer to each other than the transverse dimension of the through hole 24th

Left of the through hole 24, the long leg 22 continues a little further up to a 90 ^c -Abwinklung 31. This upward 90 ° -Abwicklung 31 is followed by a vertical leg 32, which is so far flat. At its upper end a fourth 90 ° -Abwinklung 33 is provided, which points to the right, the sum of the two 90 ° -Abwinklungen 31, 33 is not exactly 180 °, but a little more, so that the upper, horizontal leg a little is inclined towards the long leg 22, so that here, too, a terminal space is created. The upper leg 34 has in its right end portion to the right edge open U-shaped recess 36, so that two fingers 37, 38 are formed, which have a distance from each other, which can spring for themselves and in their end a respective Aufgleitkuppel 39, 41st have, which has a few degrees upwards, so that a spring force can be applied easily after sliding.

A ridge tile 42 sits on a roof, as is also known in the art. FIG. 4 shows the fold 43 to be covered, which runs substantially in the shape of a circular arc and merges with a step 44 into the outer skin of the ridge tile 42. The step 44 has a certain height, which is smaller than the upward length of the vertical leg 32. The fold 43 has in its apex portion 47 a recess 50 which is just so wide that they the long leg 22 of the clip 11th can accommodate the width. This is both a positioning and holding aid as well as a way to accommodate the long leg 22 of its thickness, so that the arcuate course of the fold 43 is practically not disturbed. If the clip 11 is pushed so as shown in Figures 3, 4 and 5, then the through hole 24 is necessarily aligned with a vertical radial hole in the fold 43, which has a diameter such that the stainless steel wire 48 from the roof inner ridge region by a 49 can push through from bottom to top without having to aim unreasonably. To be sure that the rabbet hole 49 is not completely or partially blocked, the rabble hole 49 is blown free with compressed air or the like in the manufacturing process.

As a further positioning aid is also the outer surface of the vertical leg 32, which abuts against the step 48.

The stainless steel wire 48 is attached to a rafter and / or a roof batten similar to a storm clip and runs from there according to Figure 4 to the top right, so from its inner attachment point to the fold 43 is straight and thus charged only to train.

When the upper end portion has traversed both the fold 43 and the through hole 44 and projects upwardly for a short distance, the roofer grasps the wire by hand, pulls it up and out until the desired pulling force is reached, then bends in the upper region of the seam 49 the stainless steel wire 48 away from the ridge tile 42, then pulls a little, so that the stainless steel wire 48 is pulled into the longitudinal slot 26. He pulls him into the longitudinal slot 26, so that the outwardly and upwardly directed cutting 27 and 28 dig into the stainless steel wire 48, the force is introduced from there over a large area in the fold 43 and biases it down.

Outwardly, the cutting edges 27, 28 allow the stainless steel wire 48 to slide, but not in the inward direction, which would mean loosening the hold-down cable.

The embodiment shows the stainless steel wire 48 in the longitudinal slot 26 bent in a U-shape, then extending above the long leg 22 and then bent around the leg 29 around down. You can now left that portion of the stainless steel wire 48 bent down. Or it is also possible to cut off the piece that is no longer needed. However, this would be a separate operation and would probably require tools. Otherwise, however, the roofer needs no tools. Rather, it is possible to hold the ridge tiles / stones down with a greater force, as has been the case ever since.

However, if you want to use the invention in connection with such traction means whose wires do not run obliquely downwards, as z. As Figure 5 shows, but rather with vertically upwardly extending traction means, then you can use a simpler technical requirements instead of a clip made of stainless steel such as aluminum or optionally also plastic. These then have the same shape as the clip 11, but instead of the circular through hole 24 and the longitudinal slot 26 has an oval through hole. The wire then does not need to be immovably held by cutting a cutting edge. Rather, it is then sufficient to use the edges of an oval through hole to hold the bent steel wire after his turn in a professional manner. The tension in the wire can also be generated during assembly. However, it is not necessary to plan the ridge purlin or partial lengths of ridge purlins and to obtain by such or similar measures a substantially equal draft in the stainless wires.

The embodiment shows the stainless steel wire bent in the longitudinal slot 26 U-shaped, then extending above the long leg 22 and then bent around the leg 29 around down.

Now you can leave that portion of the stainless steel wire 28 bent down. Or it is also possible to cut off the piece that is no longer needed. However, this would be a separate operation and would probably require tools. Otherwise, however, the roofer needs no tools. Rather, it is possible to hold the ridge tiles, or ridge stones with a greater force down, as has been the case ever since. However, if you want to use the invention in connection with such traction means whose wires do not run obliquely downwards, as z. As Figure 5 shows, but rather with vertically upwardly extending traction means, then you can use with simpler technical requirements instead of a clip made of stainless steel such as aluminum, or possibly also plastic. These then have the same shape as the clip 11, but instead of the circular through hole 24 and the longitudinal slot 26 has an oval through hole. The wire then does not need to be immovably held by cutting a cutting edge. Rather, it is then sufficient to use the edges of an oval through hole to hold the bent steel wire after his turn in a professional manner. The tension in the wire can also be generated during assembly. However, it is not necessary to plan the ridge purlin or partial lengths of ridge purlins in order to obtain by such or similar measures an insignificant equal train in the stainless wires.

Figure 5 shows the clip associated with the previous ridge tile and which has been designed, fastened, mounted, etc. like that just described, overlaps a nose 51 at the other end of the ridge tile 42. The upper horizontal leg 34 of the previously mounted clip lies in a depression on the otherwise horizontal nose, wherein the respective Aufgleitkuppen 39, 41 are pushed upward and so springs up the upper horizontal leg 34 and presses with its spring force the nose down, so that the other end portion of the ridge tile 42 is also held down , Since two only narrow fingers rest analogously to the fingers 37, 38 and is separated from one another by the U-cutout 36, the contact pressure downwards is practically good.

Thus, the roofer on the roof needs no tools, you can move quickly, safely and without gloves many ridge tiles so that they show much better results, as has been the case ever since, especially that they withstand stronger storms and other forces.

Below the nose 51, a depression is provided, which possibly receives the downwardly bent stainless steel wire and also the long leg 22, so that the lower fold 43 of the preceding ridge tile is not seated on the stainless steel wire of the preceding clamp or on its long leg 22.

If in the present text almost exclusively of ridge tiles, i. H. burned ridge elements was spoken, so this is just for the sake of simplicity. Accordingly, the invention also relates to ridge stones or other dry-ridge forming elements. The ridge tile shapes may also vary and the invention applied thereto without departing from the spirit of the invention.

The material thickness of the stainless steel wire is 2 mm and that of the stainless steel clamp 1 mm. For the conventional attachment to the ridge purlin one uses an aluminum material with 1, 5 mm material thickness.
