Description

THE COVERING ELEMENT AND THE METHOD FOR COVERING THE COVERING ELEMENTS

The invention relates to a cover element which is made of a sheet material only, and which cover elements can be mounted 5 in succession such that the edges of the cover element overlap with the adjacent edges of the cover element. The present invention relates to a method of forming a strip in the form of a strip into a profiled roofing strip, and to a method of cutting the covered strip into uniformly spaced roofing elements. from the cover plates. The roofing required in this way will be ordered, for example, from a dealer of molded roofs, who will supply the roofing panel cut to size. Nowadays, the formwork could also be made of standard-size roofing elements available in stock. The formwork roofing is installed by fastening the roof waterfalls of the building in quick succession and side-by-side to provide a λ-like form of roofing material.

For the functionality of the formwork to be constructed of cover elements, the edges of the cover elements 20 are e.g. the shape of the cover by requiring ta1 in the longitudinal and transverse directions of the cover. However, when installing the cover elements, · β>: it results in the intersection of the adjacent and adjacent kate-eler, ·, · * (i.e., the corners of the corners * · · of the overlapping edges, whereas the other edges of the edges lii] There are only two layers of sheet metal. As a result, a thickness change is formed between the corners and other * edges, resulting in gaps between the overlapping * * * * · "slits. from the other lower corner and from the diagonal 2

Cornering generates waste, which increases the cost of removing the cover elements and thus reduces the profitability of the manufacture. The discontinuity of the forming strip-like sheet material causes problems in the product manufacturing process and can be damaged during transport. In addition, due to the angles, the product brings sharp corners and edges that easily cause a variety of work when handling and installing the elements. Furthermore, there are additional peripherals to the manufacturing process that make it more expensive and more susceptible to various production failures. Further, roofing made of cul-de-sac elements is often perceived as more sensitive to casting than roofing made of non-cantilevered roofing elements.

The object of the invention is to provide a cover element for eliminating some of the drawbacks associated with the currently known cover elements. The object of the present invention is to disclose a covering element which prevents the disadvantages caused by the 15-ply plate layer, but with the help of λ at the corner of the elements and the problems arising therefrom. Further, the invention also provides a method for making the cup of claim 1.

The object of the invention is achieved by a cover element and a method 1 for the manufacture of a process which is characterized by what is claimed;

The cover element according to the invention is characterized in that always: a φ v * is formed on the upper surface of the cover element, below the underside of the part of the covering element surrounding the corner1, that the recess is at the step and extends to the step above [25 straight sections. Such a recess provides a layer of overlap * 'on the roof so that the other parts of the edges do not need to be covered <* · · * · "Thus, the recesses do not need to be avoided the corner on top of the joint does not pass over the recess, but rather the angle of the joint, so that the next k over the joint forms a base as smooth as possible.

In another preferred embodiment of the cover element according to the invention, the depth 5 is substantially the same as the cover over the recess. This will place the cover element on top of the corner of the cover element above the recess to the level of the upper surface of the surrounding area, resulting in a thick, flat substrate for the next sheet layer.

In a third preferred embodiment of the cover element according to the invention, the molded edges are substantially in the shape of the edges of a corner of the insert placed over the recess. In a fourth preferred embodiment of the cover element according to the invention, the lower edge is at or after the vertical portion of the stair. A list of the best possible seamless structure places the transverse joint seams of the roof in this way

In a fifth preferred embodiment of the cover element according to the invention, the depth of the recess at the vertical portion 20 is more than twice the thickness of the plate overlying the recess. Such a recess allows the adjacent cover elements to be obtained; v in exactly the same direction. Thus, in this way the transverse joint seams caused by the overlapping of the corners, which are typical of non-angled cover elements, are prevented.

The process according to the invention is characterized in that at least * *? • In the corner of the * * element, a molding foil is formed on the top surface of the cover element, mArmUrmUmnn irtvttxö ^ Änrnn alamAtin λπομ nlamVinnii o 1 n 11 (4

In a preferred embodiment of the method according to the invention, a deeper step forming device in connection with the step forming. Due to the depth of the groove, it can be manufactured by simply molding the belt to be manufactured using a pressing tool. When you go deeper; 5 is not required in addition to the turn molding devices, but the recess simply and inexpensively obtains a suitable step molding device by means of an additional molding tool.

In another preferred embodiment of the method according to the invention, 10 is moved to a position at a desired distance after the last step in the cut, and the cover element tape In this way, the stepped cover element tape can be truncated without any extra waste and waste therein.

In a third preferred embodiment of the method according to the invention, the forming device is moved to the leading edge of the cover element strip, and a step is formed into the k strip. In this way, the first step of the tape weft is always obtained at the leading edge of the tape (i.e., the lower edge of the cover element) for the song, without cutting the top of the previous cover element between the lower edge of the cover element.

The invention will now be described in more detail with reference to the following. Figure 1 shows a cover element according to the invention obliquely. Figure 2 shows a step-by-step installation of four adjacent and consecutive Figure 1 m \ 25 elements,] [Figure 3 shows a cover element according to the invention. elements there *. * ·: Principal drawing, and • teaspoon of Fig. 4 shows the breakage of stair forming and roofing elements; 3 in a phased manner.

5 rooms. Further, the cover element includes a depression 4 formed in the lower left corner at the stairs, which extends below the lower surface of the part of the covering element. The recess is horizontally 5 plates deep and 6 x 5 times the vertical portion of the staircase. The recess is the largest size of a circuit the size of the corner of the second cover element to be placed over it, and the recessed edges 7 and 8 are shaped to form the edges of the cover over the recess.

The cover elements according to the invention are formed to form a cover s 10 in such a way that the edges of the cover elements successively and next to each other overlap in the form of a dense and seamless appearance of the cover. The roofing elements are installed in such a way that the ice overlaps prevent rainwater from reaching the underside of the roof.

For example, when fixing the roofing elements according to Figure 1 to the water ceiling, the 15 manually and successively facing roofing elements are installed as shown in Figure 3 as follows: Firstly, the roofing element b is fixed above the roofing element a. the edge comes on top of the cover element a. The cover element c is then mounted on the other side of the cover, so that the upper corner of the cover element 20 is over the s lower left corner of the cover element b. Due to the thick recess of the cover element, the top surface of the cover element and the upper surface of the left region around recess s of element b are at approximately the same level. In addition, since the element s · · · · · · is twice the margin e at the vertical portion of the step, the vertical portion of the upper step of element c relative to the seam is equal to one plate thickness of the silicon elements. above. Next, next to the element b above the element c, a point d, whose right side edge is the left side edge of the element b * * * ·· 'whose lower corner is over the upper corner of the element c. Because the margin ^ 0 spacing and h vacsn rpnna nvvvti naVeiiiiccimmini 116 6 times the transverse attachment of adjacent cover elements in the tea, viewed from the side of the cover, is straight due to the depth recess portion of the cover element.

Fig. 3 shows a dingy production line 10 of only a cover element 5 according to the invention. It comprises a reel opening device 11 on a reel for opening a ribbon 9, a roll forming machine 12 for longitudinal loading These devices are largely devoid of structure and function, so that they will only be described with respect to the related LI functions required by the invention. For example, the step forming device 13 includes, in addition to the parts, a forming tool in connection with the upper and lower pressing tool included in the device, by means of which the above elements are pressed into the steps. In this case, the recess forming tool is formed by a recess formed by a recess formed in the upper tool 15 of the grooving device. Fixed stair forming, which forms a recess in each stair. Alternatively (the projection in the top and bottom tools of the forming device and the like is to be actuated so that the recesses can only be stepped on the stairs at the bottom of the cover elements.

In those roofing elements according to the invention, which include the staggered # · β · * stairs, the lower edge is positioned at the vertical portion of the stair at a distance ♦ · · [\ thereafter. To get the bottom of all kate-eler. 1, would require, after cutting the 25-country tape, a waste piece to the next cover element * · * to obtain the first step at the bottom of the cover element. In the production line of this Figure 1, the step forming device 13 and ka is attached to the production line 10 in the longitudinal direction of the covering element strip. down the stairs. In step 3, the cover element strip is cut to give the first finished cover element. In the next step 4, the molding of the element is started by moving the molding device to the stair, so that this step can be formed at the leading edge of the profiled strip. The step forming device and the cutting device are moved back to their home position. Ί continue production from step 1 onwards until the amount of diluent is complete.

The cover element according to the invention is not limited to the above example. It is essential to the cover element according to the invention that it also hinges on one corner of the cover element, on the upper surface of the cover element at least partly on the lower surface of the part of the covering element which surrounds it; a recess which is located at the staircase and extends into a straight section above the staircase and which allows the formation of a roof without the four plies of boards formed at the corners of the road 15. The size of the cover element, the shape of the profile and the number, shape and height of the cover steps may vary. In addition, the cover may be of the top type, whereby the clamping element of the cladding element overlies the top sheet layer or 20, wherein the clamping elements of the cladding element are disposed so as to hide beneath the edge of the upper cladding element. 1; there is a recess therein, at the second end of each step of the covering element; : Y: in principle, it would be sufficient for the recess to be made only on the lower Porta

However, it should be noted that this would slightly complicate the marginalization process and, on the other hand, the · · #: disadvantages of the recesses on all stairs, as they will always be hidden under the next unobstructed edge in the finished cover. In addition, the details of the covering element may vary. For example, the lower edge of the cover element is usually at or just a short distance from a vertical part • · · ··· · In 30 applications, the lower edge may be positioned e.g. close to the vertical edge of the staircase. elements.

Also, the above method of covering the elemental sex according to the invention may vary e.g. depending on the size of the cover element, the profile shape and the material of the panel. The steps of manufacturing known per se, such as, for example, shaping a longitudinal profile, can be used to form any sheet material known per se and to cut into the mold of the recess part of the cover according to the invention in conjunction with or separately from other forming steps. The Ni 10 where the recess is made in connection with the step forming step is provided with an edi tool in connection with the top and / or bottom tool of the step forming device. In the manufacture of the glass roofing elements, the recess is provided by a projection formed in the upper tool of the forming device and the lower tool is provided by a recess-shaped recess. If the recess only comes to Alii 15, the recess shaping tool must work so that the recess only reaches the lowest step. This can be accomplished by installing a recess-actuating actuator in the top tool of the es step molding device to pull the projection into the top tool during the lower step molding. In addition, the recess molding P 20 may be adjustable so that the depth and / or size of the recess may be: n i a ♦ · * based on the thickness of the plate and / or the shape of the cover elements.
