Description

HIDDEN FIXED COVER

The invention relates to a concealed cover element which is made of sheet material and which cover elements can be mounted; one after the other so that the edges of the cover elements overlap adjacent the edges of the cover elements, and to which one of the cover elements extends substantially across the roof. a step having a locking recess for locking the cover element from at least one of the steps downstream of the cover element, the cover element including a securing projection at the top of the cover element to override the cover element and to tighten and lock the at least locking recess to the locking recess at the top of the i-side cover element

The currently known roofing elements, which can be used to assemble a roofing roof covering from a roofing slab, are fixed to the boards as waterproof roofing boards <15, side by side, with nails, screws or other means. Often, such cover elements are concealed, with points positioned at points that remain in the adjacent cover. To ensure that the cover elements are held in place and to control the wind, there are cover elements which include the invisible; 20 elements, of which adjacent or consecutive cover elements are secured by means of fastening means. Such roofing elements / roofing or: Y; U.S. Patent Nos. 3,220,150; and 5,752,355. In addition, the most popular * * mus. Publication WO 2004001155 is known from the sheet material muc ....: a brick-faced roofing element having a brick-patterned shape with 25 vertical sections, locking recesses at the valleys of the profile, where "!! overlapping stairs with the help of spiky mounting projections at the top of the upper road.

• · · * · 9 • · »:" ': The current fixing methods make it possible to attach roofing elements as such 2-way roofing elements are very fast and easy to install and would otherwise provide a very good location of the roofing elements. However, the problem with the element is that the forming of the recess in the cover element 5 by forming a metal sheet requires the molding tool to be mounted with the locking tool to be mounted with the tool, which is complicated in structure and relatively costly in manufacturing. temporarily stationary, restricts the production rate attainable by the molding device to form the locking recess.

It is an object of the invention to provide a hidden fastener cover by removing the aforementioned points of the currently known cover elements. In particular, it is an object of the invention to provide a cover element <15 secured to one another without separate fastening means between the two, which does not increase the manufacturing cost of the sheet metal forming machine and does not limit the production rate achieved with such a mold.

The object of the invention is achieved by a cover fastener 20 which is concealed and is similar to what is claimed.

The roofing element according to the invention is characterized in that, viewed from the direction p1l, it is essentially straight, inclined to the roof surfaces * * * ··· [va part of the roofing element, wherein the longitudinal polarization of the roofing element in the area of the stair Z-shaped. As a result, the staircase of the k ..T 25 becomes so obliquely forward that the lower edge of the upper roofing element over the top of the lower deck fits into the lower roofing stage when the roofing elements are tightened: longitudinally at the top of the roofing elements of those who are attached · **. through. Thus, such a locking recess can be formed as a tool for creating a step 3 and is as simple as the conventional tool for forming a straight stepped brickwork or step for molding. Furthermore, in such a cover element, all the means for attaching the cover elements remain invisible in the finished cover. Further, the production of the groove does not increase the sheet metal sheet by forming the manufacturing line for the cover element manufacturing line with the slate roofing element production line, but unlike non-kinking cover elements, such cover elements v 10 are successively interposed between separate

In a preferred embodiment of the invention, the locking recess is substantially in the width of the cover element in the direction of the cover element. However, the molding tool does not need to make projections or other intermediate shapes, but the m can be simply fabricated. In addition, such a locking depth element makes the attachment to one another extremely durable, since the adhesive surface between the hs is of the entire width of the cover element.

In another preferred embodiment of the invention, the junction of the lower portions 20 of the cover element and the junction between the elements between the step and the lower roof surface is rendered invisible under the upper roof surface of the lower roof surface. This makes the finished cover sa * 9. "·. Its and seamless looking.

In the following, the invention will be described in more detail with reference to the accompanying drawings, in which: ** Fig. 1 shows a concealed mounting oblique view of the invention from above, Fig. 2 illustrates two i by forming the transverse profile valleys 2 and the peak into a strip of sheet steel sheet by means of a roll forming machine, which consisted of successive forming steps (pairs of forming rolls). In this case, as shown in Fig. 1, the valleys 2 and the peaks 3 of the wave profile are symmetrically symmetrically about the same width.

After forming the transverse profile, a strip forming device is formed on the strip at intervals 4a and 4b of the roof tile by means of a step forming device after the roll. The stairs are made according to the principle shown in Fig. 3, and the molding moves between the retaining tool P and the retaining tool V in an oblique downward direction with respect to the profiled strip N held on the molding 10. In this way, the staircase 1 is inclined so that, viewed from the roof ridge, the uppermost stage extends a distance from the stairway to the lower roof, whereby the recesses 5a and 5b are formed throughout the width of the roofing element 15. The transverse profile, the stairs (and after the locking depth, the finished cover element strip is cut into cutting devices. In this case, the cover elements are one brick-patterned cover element having two steps 4a and 4b) and their width is longitudinal cover elements. In the finished cover of the roofing elements 20, the projections 6 are shown in connection with the cutting of the roof surface on the haqa side of the roofing roof. They are shown in Fig. ·· *, beams formed from the top down to the upper step. At the top of the clamps is a clamp rc!. *. in this case are provided with the cutting device blades ϊ * ·· \ 25 by means of chisel tools or can be made separately in a separate step: # * *: * The cover elements 1 and 2 are formed into a waterproofing cover by attaching the cover element • * * Horizontal rows for fastening structures (usually from right to left *. ·.

Alternatively, the roofing elements can be l 5 along the road at the bottom of the elements extends over the upper step 4a of the lower cover element row Each cover element is secured at the upper edge of the cover element by the projections 6 so that the lower hole 5 at the lower edge of the cover element against the upper step 4a of the next lower element. inclined stairs overlapping elements (ie locking recess locking In addition, the lugs 6 on the lower lining edge and the attachment members therein are not visible underneath the lower edge of the lining, i.e. the upper lugs on the ridge extending to the ridge of the finished cover 10 and their fastening members remain visible. These too are covered in that phase! a haqapel that extends over the top projections of the top cover element is mounted on the brush. Since there is no more row of cover elements after the lower hinge closest to the eaves, all lower hinges must be secured to the lower part of the hood and the auxiliary board (not shown).

The cover element according to the invention may differ in many respects from the branded application and the cover element may also be made of a material other than a coated steel sheet. Suitable Material 20 Many sheet materials made of copper, aluminum or plastic ... may be pre-coated or uncoated, whereby the silicon • * *; ·; * will cure after the manufacturing of the cover elements. The number of transverse profile m \ (brick pattern) as well as the number of profile wires included in one roofing element may vary. All profile shapes for which a step such as the one illustrated in Figures 1 and 2 are applicable are inherent. The design of the stairs in the roof elements may vary in a tiled application, the stair is the part of the roof element in the tilted horizontal position of the roof element, i.e. in the region of the stairs kat (.; \ Cross-section is Z-shaped. .curve inwards or outwards in a suitable manner or, eg, in the area of * m 6). At this point, the lower edge is generally still invisible to the upper 1, since, for example, in the embodiment shown in Figures 1 and 2, the applied roof surface 7a extends about 7 mm lower due to the slanting of the stair.

The clamping projections at the top of the cover element are the cover members extending to the bottom of the lower surface of the transverse profile valley so that nails or screws mounted in the clamping projections do not bend the upper edge, and that Thus, instead of the bellows made by cutting, for example, the projections of the clamping projections may be elevated depressions of the cover element, which have the shape of the locally bellows bellows of figure 1. If pre-ribs are used as fastening elements, no pre-mounted fastening holes are required. In which of the fixing projections 15, indentations have been made at the holes, e.g., through the cover element 1 for turning ordinary wood or sheet screws.

Also, the manufacturing of the cover element can take place in many different ways than in the exemplary embodiment. The support used for the manufacture need to be continuous in the manner described above, but the covering profile and the stairs formed in the above manner, fixed: V: other details may be formed by any suitable method, ***: into pieces of suitable size.
