KATE-ELEMENT

ί

The invention relates to a covering element made of sheet material, which cover elements can be mounted side by side and in succession such that the edges of the cover elements overlap with the edges of the adjacent cover elements by the covering element comprises at least one substantially transverse step of the covering.

The roofing sheet, which is made up of roofing panels, can be formed either from roofing panels extending from the shark to the eaves of the roof or generally from smaller roofing elements. The shingle made of roofing elements is formed by fastening the roofing elements 10 side by side and in succession to the roofing attachment structures of the roof, so as to obtain a functional and appearance-like roofing covering made of roofing panels extending from the eaves. Nowadays, individual roofing elements are usually attached directly to nail, screws or other suitable fastening elements to the rafters which are fastening structures to the roof. Often, the cover elements are concealed fasteners, whereby the attachment points are located at positions that are hidden under the adjacent cover element. In addition, various interlocking roofing elements and roof tiles are now known. US 3,220,150 discloses roofing bricks made of plastic, metal or clay with lugs at the top and bottom, f * of which the roof tiles can be attached in series with pins, wire or the like.

': 20 with separate fastening means. U.S. Patent No. 5,752,355 discloses a sheet metal cover element having a first side edge with a bending member. a tongue-shaped projection formed by a club and having grooves formed at one side or by a tuft to which the tongue-shaped projections can be fitted to engage adjacent cover elements.

25 With current attachment methods, the roofing elements are secured as such and the roof, * provides a dense and uniform appearance. However, installing a roof made of known methods (t: roofing elements) requires a relatively time-consuming job of fastening fasteners such as nails or screws. The currently known interlocking elements of various types of roofing elements; often slowing down and cumbersome installation, because joints require separate> / -: fasteners to be installed between the roofing elements / roofing tiles and, in the case of roofing elements / roofing tiles made without separate fastening elements, making joints due to their complexity is often unnecessarily cumbersome and slow. This increases the overall cost of the margin, which makes the margin less competitive with other margin options.

It is an object of the invention to provide a cover element which eliminates the aforementioned disadvantages associated with the current cover elements. In particular, it is an object of the invention to provide a cover element which can be attached to other cover elements! 5 and the roof fastening structures in a durable and reliable manner, but with fewer separate fastening elements and associated installation work. It is a further object of the invention to provide a cover element whose attachment tip improves the wind load resistance of the cover.

The object of the invention is achieved by a cover element which is characterized by what is claimed.

The cover element according to the invention is characterized in that the cover element steps have at least one locking recess for locking the cover element from at least one step to the next lower cover element, and that at least one securing projection is provided at the top of the cover element and at least the lower edge of the cover element for tightening and locking the locking recesses 15 located in the upper part of the next cover element below. Such locking recesses allow the cover elements to be secured to one another, which reduces the number of separate attachment elements required and speeds up and facilitates the installation of the cover. Especially when the step with the locking recess is at the bottom of the roof 20, wind loads tearing the cover elements very well are obtained; 'Durable roof structure. Thanks to the fixing projections at the top of the cover element, the locking recesses on the overlapping steps of two successive cover elements can be tightened easily and quickly against each other during installation so that the locking of the cover edge formed by the locking recesses is not loose. . 25 whispers and buzzing in the wind, but it is durable, silent and tight.

'·· - * In a preferred embodiment of the invention, the locking recess is a depression extending from the vertical portion of the stair mainly in the direction of the top edge of the covering element. The construction of such a locking recess .. ':' is simply accomplished by an additional tool to be attached to the pavement element L .. · 'or a step forming tool,. 30 design. In addition, such a locking recess locks the cover element into the next! to the lower cover element so that the fastening can withstand wind loads tearing open the roof well.

: In another preferred embodiment of the invention, the depression, when viewed from the side, is in the form of a letter "V" on its side. Due to the conical locking recess 35 thus formed, the locking recesses which are nested inside need not be made different in size to obtain the locking recesses of the lower and the upper covering elements which enter therein. Such locking recesses can also be easily tightened against one another when the upper cover element is pulled up in the direction of the roof ridge. In addition, it is possible to make such a depression on a relatively low staircase in the covering element.

In a third preferred embodiment of the invention, the locking recesses are disposed about the valleys of the transverse profile of the cover element. The valleys of the cover element, i.e. the areas of the transverse profile of the cover element which are closest to the ribs in the finished cover, are advantageous because they can best be secured by fastening elements at the top of the next 10 lower cover elements. the lower edges of the elements could be fixed as rigidly as possible through the upper edge of the next lower covering element to the roof fastening structures. In addition, valleys are wider than the peaks in most roofs, allowing for wider locking recesses than for peaks.

In a fourth preferred embodiment of the invention, the fixing projection is a portion formed below the lower surface of the covering element formed at the upper edge of the cover element, including a mounting member for securing the mounting projection to the cover mounting structure. Generally, there is a step near the top edge of the cover element, otherwise the overlapping areas of the overlapping cover elements will increase, which increases the amount of sheet material required for the cover. As a result, the cover attachment: '·. The construction of the batten board comes under the staircase and therefore the upper edge above the batten remains at a distance of the height of the staircase from the upper surface of the battenboard.

«« · A; ; In order to secure the top edge of the cover element by means of a fastening member against the ribbed board, the top edge of the cover element must be bent downward quite strongly. This is not. succeed because this causes the top of the cover element to shrink in the width direction of the cover, which in turn causes installation problems. The attachment protrusion avoids these on-. the beads and the top edge of the cover element can be secured as a cover attachment structure; to the existing rafters.

In a fifth preferred embodiment of the invention, the securing projection is a bellows which is! formed by cuts extending from the top edge of the cover element to the lower edge of the cover element. The advantage of such an attachment projection is that, as the bellows bends downwards, it at the same time pulls the cover element upwards when the attachment is started with the bellows parallel to the other upper edge. Furthermore, the manufacture of such an attachment projection is relatively simple and can be easily accomplished in connection with cutting the cover element.

In a sixth preferred embodiment of the invention, the securing projections are disposed about the valleys of the transverse profile of the cover element. These points are closest to the ribs, whereby the projection does not have to extend as far down the underside of the roof as if the securing projections were at the tops of the transverse profile 5. In addition, if the locking recesses are located around the valleys, a better tightening of the locking recesses is achieved if the locking projections are also located along the valleys of the transverse profile.

The invention will now be described in more detail with reference to the accompanying drawings, in which Figure 10 shows the principle of installing three cover elements according to the invention when assembling the cover, Figure 2 shows the front cover shown in Figure 1 and Figure 3 is a top view .

1-3 are made of a coated steel sheet 15 strip in a continuous production line comprising a tape reel opening device, a roll forming machine, a press type step forming device and a cutting device. First, a transverse profile of the cover element is formed on the strip by forming the profile peaks 9 and valleys 10 into a coil-to-open sheet steel sheet by a roll forming machine with a suitable number of successive forming steps (molding-20 pairs of rolls). In this case, the shape of the transverse profile is wavy, as shown in the figures, so that the valleys 10 are slightly wider than the peaks 9. After the transverse profile is formed, the stairs 4a and 4b at intervals of the roof tiles are formed on the strip by a step forming device located downstream of the roll forming machine.

'· *' 30 locking recesses on the side of the cover forming element of the stair forming tool:: from the side to the vertical part of the stair at the moment when the upper weighting tool on the stair belt is in the lower position. After forming the transverse profile, the stairs and the locking recesses, the finished cover element strip is cut off by means of a cutting device into cover elements. In this case, the cover elements are one brick pattern interval and their width is longer than the length, i.e. the cover elements are so-called horizontal elements. At the upper edge of the roofing elements, i.e. at the edge of the roofing ridge of the finished roof, fastening projections are formed during cutting. They are beams formed by cuts extending from the top to the bottom, as shown in Figures 1 and 3. There are mounting holes at the top of the mounting projections. They are also provided in this case by punching tools mounted in connection with the blades of the cutting device 5.

The roof elements 1-3 are formed into a roof-like roof by attaching the roof elements to the roof roof fastening structures according to the principle shown in Figure 1. 1-3, the roofing elements (e.g., wooden rafters) are secured to the roof ceiling attachment structures (e.g., wooden laths) by attaching holes 7 in the top bracket projections 6 with tongue nails or screws 8. The roofing elements may also be secured by other suitable fastening means. For example, metal rafters can be secured with suitable rivets or sheet metal screws.

When assembling the cover as shown in Fig. 1, the lowest right-hand cover element 1 is attached first. All cover elements in the lower row are secured by separate additional fastening means between the lower part of the cover element and the model board (not shown). Next, the adjacent cover element 2 on the left side of the cover element 1 is fastened so that the top portion of the transverse profile located on the right edge of the cover element 2 overlies the top part 9 of the first cover element so that the right edge 20 of the cover element 2 to the right of the profile peak on the left side of the cover element 1.

· * The horizontal overlap thus formed ensures the watertightness of the longitudinal joints formed in the roof. After attaching the second cover element 2, the third cover above the cover element 1 is fastened; ·. element 3 with its lower edge over the top step 4a of the cover element 1: 25 and the locking recesses of the step at the bottom thereof are located on the cover element 1. ···. the locking recesses 5a of the stair 4a. In this way, the so-called vertical overlaps are formed on the successive roofing elements, and in this way the roofing element 3 is secured from its lower part to the upper part of the roofing element 1, which are adjacent to the roof fastening structures; then securing the fourth cover element (not shown) to the upper side 9 of the cover element 2 (not shown) so that the locking recesses at its lower part: are tightened to the upper locking element closest to the upper edge of the cover element 2; recesses, whereby the lower edge of the fourth covering element is locked to the upper part of the covering element 2 in a manner corresponding to the lower edge of the covering element 3 and such that the horizontal overlap corresponds to the horizontal overlap between the covering elements 1 and 2. In this way, the fixing of the cover elements 35 is continued, proceeding from right to left and from bottom to top until the entire roof is covered from the eaves to the ridge. If desired, the assembly of the cover i 6 114729 I can also be started from the bottom left of the roof and proceed from the left to the right. The roof panel, the necessary roof trim strips, eaves gutters, etc. to the roof ridge are secured to the roof in a manner known per se after the roof elements have been fixed.

The cover element according to the invention may differ in many respects from the exemplary embodiment described above, and the cover element may also be made of a suitable material other than a coated steel sheet. Suitable materials are, for example, many sheet materials made of copper, aluminum or plastic. Materials! may be pre-coated or uncoated, whereupon the coating may take place after the coating elements have been manufactured. 1-3, the cover element may also be a so-called vertical element, whereby its length is greater than the width, or the cover element may be a horizontal element, which includes more tiles than the one shown in Figures 1-3 to provide several consecutive brick patterns. element consists of two steps. The shape of the Poi-15 friction profile, as well as the number of profile peaks and valleys belonging to one roofing element, may vary. All such profile shapes that can be formed in a step-like manner (e.g., a brick pattern) in Figures 1-3 are in principle possible. In addition, the cover element may also be completely un profiled. In this case, the cover element is, at its simplest, a transverse straight plate cap 20, which comprises one or more transverse steps (depending on the size of the cover element and the spacing), with at least one locking recess. The vertical part of the stairs need not be completely vertical, but it may also be '· slightly forward or backward sloping. Locking recess for stair; Also, the longitudinal cross-section need not necessarily have the shape of a "V" on its side as shown in Figure 1. Alternatively, the locking recess may be shaped, e.g., curved, rectangular or any suitable combination of these. In the case of the profiled roofing element, the locking recesses may be located not only at each of the valleys in the transverse profile, but also at the tops of the profile or e.g. only at every other valley and the width of the locking recess 30 may naturally vary e.g. depending on the shape of the transverse profile. The attachment projections at the top of the * • cover element are parts of the cover element extending · * below the lower end of the valley lower surface of the transverse profile so as not to. · The nails or screws installed in the mounting projections bend the top of the cover element.

Thus, the securing projections may be formed from the inside of the bellows made by cutting, e.g., to the top of the cover element, which have the shape of the bellows of the attached cover element according to Figures 1-3. If so-called drill screws are used as fastening elements, the mounting holes 7114729 are not required. Further, the mounting projections may have recesses of slightly larger diameter, circular or other shapes at the base of the mounting member, with a mounting hole for a nail, screw or other suitable fastening member in the center, if necessary.

; 5 The manufacturing of the cover element can also take place in many different ways. The production line used for the manufacture need not be continuous in the manner described above, but the transverse profile and staggering of the cover elements, as well as the locking recesses, fastening projections and other details may be formed by any suitable method, e.g.

Thus, for example, the transverse profile, when using moldable sheet materials, can be made by means of a press-type forming device instead of roll forming. In addition, when continuous methods such as those used to make the embodiment of Figures 1-3 are used, the manufacturing steps may be carried out in a variety of ways differently from the method described in connection with the application of Figures 1-3.

For example, the manufacture of the locking recesses can be accomplished by a separate locking recess molding device located downstream of the step forming device or the cover element cutting device. Correspondingly, it is also possible to manufacture the fixing projections after cutting the cover elements, for example, in a separate work step, or completely separate from the other manufacturing steps of the cover element. Further, e.g. the manufacture of fixing holes for the clamping projections may be carried out at different stages of the manufacturing process of the cover element or e.g. ·: # In the same workstation as other manufacturing steps.
