The opening includes at least one edge formed transverse to the longitudinal extent of the body, the edge being formed at least in part by a bend in the body. The folded portion forms at least a double layer region of the main body together with the adjacent portion of the main body. The folds are connected with adjacent parts at least in the region of the double layer so as to increase the lateral stiffness relative to the longitudinal extent of the profiled element. The invention further relates to a method for manufacturing such profiled elements.

Description

  The present invention relates to a section element, in particular having an elongated substrate, in particular comprising metal or plastic, in which at least one opening is formed, for example, a dry structure, a building front, a plaster, a screed Or a structural part such as a tile part. The invention further relates to a method of manufacturing such a compartment element.

  This type of partition element is also known, for example, from US Pat. The elongate substrate is provided with a predetermined cutting pattern for producing, for example, a partition element. Upon selection of an appropriate cutting pattern, the two parallel extending longitudinal portions of the compartment element are pulled apart in the folding process, thereby expanding the compartment element without additional material input. The longitudinal portions separated in this respect are connected to each other via a connecting element formed integrally with the longitudinal portion. The corresponding cutting pattern is disclosed in Patent Document 1, and the contents thereof, particularly the contents related to the cutting patterns disclosed in the specification, are explicitly included in the disclosure contents of the present invention.

  A further possibility for the production of an expanded compartment element is described in US Pat. In this description, it is described in particular that the compartment elements are not produced by a folding process, but by a pure expansion process in which the slits introduced into the compartments are separated to expand to a diamond-shaped opening. Has been. Such compartment elements are used in particular for the production of upright parts. The contents of this specification, particularly those related to the cutting patterns described in this specification, are also expressly included in the disclosure of the present invention.

  It is also possible to produce the corresponding compartment element without an expansion or folding process, for example as usual for normal upright parts, but the substrate is substantially unstretched, Has a closed design. These types of openings are introduced into the substrate, for example, by a punching process. This is disadvantageous in that the stamped material becomes a waste material, which increases the manufacturing cost of these compartment elements.

  In general, in many cases, these aforementioned types of compartment elements, particularly upright sections, pass not only through piping or other hollow bodies, but also through cables, wires, or other elongated band-like or cord-like elements. It is desirable to provide a through opening. Regardless of whether such a through opening is formed by punching a hole corresponding to the substrate, formed by the bending process described above, or formed by pulling, the partition element is formed. There is the problem of having a low stiffness in the transverse direction with respect to the area of the opening, in particular the longitudinal extent of the partition element.

  The object of the present invention is to provide a compartment element with increased stiffness in the area of the opening relative to a conventional compartment element.

  Based on the opening compartment element, the aim is that the opening is formed transversely to the longitudinal extent of the substrate and at least one edge formed at least in part by a bent portion of the substrate The bent portion forms an area of at least a double layer of the substrate together with an adjacent portion of the base body, and the bent portion is connected to the adjacent portion within the area of the at least double layer, It is satisfied by the present invention that increases the stiffness in the transverse direction to the longitudinal extent.

  The method of manufacturing such a partition element designed according to the present invention introduces a slit for folding out a part of the base into the base and develops the part so as to form an opening in the base. Then, a part of the substrate is bent along a kink line extending in a transverse direction with respect to the longitudinal range of the substrate and connecting the slits, and the bent portion together with the adjacent portion of the substrate Bending until at least a double layer region is formed and connecting the bend to an adjacent portion within the at least double layer to increase the lateral stiffness relative to the longitudinal extent of the partition element. It is characterized by.

  According to the invention, at least a double-layer region is produced directly in the region of the edge of the opening that extends transversely to the longitudinal direction of the partition element, so that no deviation occurs between the two layers. Thus, by connecting the individual layers in that region together, the reduction in stiffness caused by the opening is compensated. At least one of the layers is formed by a material portion that forms at least one region of the opening by developing the substrate. Thereby, on the one hand, it is realized that the material used for forming the opening is not wasted, but rather is used for reinforcing the substrate. On the other hand, folding the part from the opening automatically ensures that a direct reinforcing effect is provided in the area of the opening, ie in the area of the defect formed by the opening. In this regard, the term “lateral direction” should be understood as any direction that does not extend only in the longitudinal direction of the compartment element. As long as the laterally extending edge extends in a direction transverse to the longitudinal direction of the compartment element at least in the region of the part, the laterally extending edge is formed in particular as a straight line or a curved line. Also good.

  Furthermore, there is no need to provide separate parts to increase the rigidity as a result of the integral connection of the parts bent from the substrate. Due to the integral connection of the bent part with the substrate, it is possible to produce a reinforced area by an on-line process at ultra-high speeds much faster than 100 m / min.

  According to an advantageous embodiment of the invention, the edge extends at least locally substantially perpendicular to the longitudinal extent of the substrate. This provides a uniform support edge for passing lines through openings or the like. At the same time, the bilayer region also extends perpendicular to the longitudinal extent of the substrate, and an increase in stiffness is achieved in an ideal manner in a direction perpendicular to the longitudinal extent of the substrate.

  In a further preferred embodiment of the invention, the folds are connected to adjacent parts by compression bonding processes such as clinching or crimping, clamping, drawing, pressing, welding, screwing, bond bonding or riveting. The stronger the connection between the bent portion and the adjacent portion of the base body, the more rigid the partition element. In particular, the use of a selected connection process prevents shear movement between layers in the multilayer region, for example arching of the compartment elements.

  The edge is preferably formed over the entire length by the bent portion. This is the case, for example, when the substrate is not separated into two separated longitudinal portions by the above-described bending process, but rather to form a substantially closed surface. In this case, after introducing the corresponding slits into the base, the portions defined by the slits may be folded from the base, and the edge generated when the portions are folded over the entire length of the opening generated by the bending. Extends automatically. In this case, since the edge is formed as a kink edge over its entire length, it is ensured that the edge has a certain roundness, rather than being formed as a sharp edge. Thereby, the line passed through the opening can be applied to the edge without risk of damage.

  According to a further advantageous embodiment of the invention, the first part of the edge is formed by a fold. The second part of the edge formed by the unfolded part of the substrate is preferably adjacent to the first part of the edge. In this regard, the unfolded part can in particular form at least part of the adjacent part of the substrate. The first part of the edge is preferably formed by a single layer fold, which is at least one second part of the edge formed by the double layer fold of the substrate. Adjacent to.

  This design is particularly reasonable when the substrate is divided into two longitudinal portions that are drawn apart by the aforementioned folding process. The opening already generated by the expansion process is further enlarged by the corresponding folds so that the edge portions that are joined together are, for example, the folds of the first longitudinal part and the second longitudinal part of the substrate. It is formed by both the unfolded part. In this case, the folded portion forms a double layer region with both the first longitudinal portion and the second longitudinal portion, and is folded to a corresponding adjacent portion so as to achieve increased rigidity. Partial connections are established both in one of the double layer regions and in the plurality of double layer regions.

  In this embodiment, the substrate advantageously comprises two mutually spaced longitudinal portions, which extend in parallel with each other and are integrally formed with the longitudinal portions and in each case A plurality of connecting points are connected to each other via a connecting element that bridges the interval between the longitudinal portions, and the opening extends from one longitudinal portion to the other longitudinal portion beyond the interval. The bend forms an edge region that bridges the spacing between the longitudinal portions.

  According to a further advantageous embodiment of the invention, the opening comprises at least two edges formed corresponding to the opening, in particular arranged on opposite sides. This achieves the desired improved stiffness on the sides disposed on opposite sides of the opening, and as a whole, the higher rigidity of the partition element in the region of the opening.

  According to a further preferred embodiment of the present invention, the partition element comprises a C-shaped section (C section), a U-shaped section (U section), an L-shaped section (L section), a T-shaped section (T section). , H-shaped cross section (H section), hat-shaped cross section (hat section), or Z-shaped cross section (Z section).

  According to a further advantageous embodiment of the invention, the cover element at least locally engages the edge, in particular the edge is surrounded by the cover element. This is especially reasonable in the sharp design of the edge, since in this case the line passed through the opening does not extend over the sharply formed edge but on the cover element covering the periphery of the edge. This ensures that no damage is caused to the element passed through the opening. In this respect, the cover element not only engages around the support edge, but is advantageously formed to engage over the entire periphery of the opening and in particular to surround the entire periphery.

  The edge preferably comprises at least a local bend, in particular a flange. In general, however, in addition to the aforementioned cover elements, this is particularly done as an alternative. This is also achieved by a fold formed so that the support of the line through the opening is rounded, despite all forms of the edge as a sharp edge. Thereby, damage to the element passing through the opening is avoided.

  As already mentioned, the opening is advantageously formed in particular as a through-opening for the electric wire, but it is also possible for the opening to fulfill a different function in general. The openings are used in particular as passage openings for other materials, for example air flow holes or insulating materials. Also, the reinforcement of the compartment element is achieved in this case by the design of the invention.

  Advantageously, it is provided that a plurality of openings are distributed, in particular in the longitudinal direction of the substrate. In this regard, the openings are particularly evenly spaced. The flexible use of partition elements for passing lines or cables designed according to the present invention is further improved by the arrangement of a plurality of openings.

  Further advantageous embodiments of the invention are described in the dependent claims.

  The invention is described in detail below with reference to examples and drawings.

The figure which shows the detail of the strip-shaped material part which has the cutting pattern which manufactures the division element formed by this invention. FIG. 3 is a diagram of a C-shaped compartment formed according to the present invention. The figure which shows the detail of the strip-shaped material part which has the cutting pattern changed further. FIG. 4 is an illustration of the metal element after unfolding FIG. 3. FIG. 4 is a view of a further C-shaped section of the present invention formed by the cutting pattern of FIG. 3. The perspective view of a cover element. FIG. 6 is a perspective view of another cover element. The figure which shows four different processes at the time of manufacture of another Example of this invention.

  FIG. 1 shows an elongated planar material portion 1 comprising, for example, metal, plastic or other suitable material for manufacturing the compartment element of the present invention. The material portion 1 is adjacent to the base portion 3 extending in the longitudinal direction and the lateral direction of the base portion 3, and in any case, at 90 ° along the broken line 6 so as to form the upright portion 7 shown in FIG. And an elongate substrate 2 that includes two portions 4 that are folded to form a rim 5 (FIG. 2). In this respect, the edge 8 arranged outside the part 4 makes a 90 ° angle with respect to the rim 5 and thus forms a C-shaped upright part 7.

  A plurality of slits 9 and 10 are formed in the base 3 of the base 2, and the slit 9 extends in the longitudinal direction of the base 2, and the slit 10 extends in the vertical direction thereof. In this regard, the slits 9 and 10 are formed by, for example, rotary stamping, laser cutting, or other appropriate cutting method or stamping method.

  Each of the two slits 9 is connected by a kink line 11 indicated by a broken line, and the portion 12 of the base 2 is bent along the line to form an opening 13 (FIG. 2). The edge portions 14 of the openings 13 are formed by the bent portions 12 of FIG. 2 and extend in the lateral direction, particularly perpendicular to the longitudinal direction of the substrate 2. The bent portion 12 of the base 2 is bent as shown in FIG. 2, and comes into surface contact with the adjacent portion 15 of the base 2 shown by the hatched area in FIG. The bent portion 12 together with the adjacent portion 15 forms the double layer portion 16 of the base 2, and in each case, when viewed from the longitudinal direction of the base 2, the bent portion 12 is arranged so as to be immediately adjacent to the opening 13.

  Further, as can be recognized from FIG. 2, for example, connecting means 17 formed as a rivet portion is provided, and the bent portion 12 is fixedly connected to the adjacent portion 15 by the connecting means. The connecting means 17 prevents relative movement between the bent portion 12 and the adjacent portion 15, thereby reinforcing the base 2 in the region of the opening 13, that is, the region whose strength is weakened by the opening 13. Is achieved directly. Due to this reinforcing effect, for example, in use as an upright portion, it is possible to avoid the bending of the base portion 3 due to the lateral load of the rim 5 that is generated when a screw is attached when a thick plate member is attached.

  The opening 13 is used as a conduction element such as an electric wire 18. Since the edges 14 are each formed by a bend 12, the edges 14 are not sharp but rather have a certain roundness. Thereby, the damage which arises in the insulator of the electric wire 18 concerning the edge part 14 is avoided.

  FIG. 3 shows a material part 19 having a base body 35, which has a plurality of slits 20 extending in an oblique direction and extending along a longitudinal range of the material part 19. Corresponding cutting patterns and improved cutting patterns are described in US Pat. No. 6,057,049, and the disclosure content related to the use of cutting patterns to expand different possible cutting patterns and material parts is explicitly disclosed in the present invention. included.

  In addition to the slits that form these known cutting patterns, the slit 22 is adjacent to each of the two slits 21 that extend obliquely and extends perpendicular to the longitudinal direction of the material portion 19 as shown in FIG. Formed to exist. A slit 23 extending in the longitudinal direction of the material part 19 is adjacent to each of the slits 22 and then adjacent to an additional slit 24 extending parallel to each slit 22. Next, the ends of the two slits 24 are connected to each other by a slit 25 extending in the longitudinal direction.

  Starting from approximately the center of the slits 25, additional slits 26 then extend parallel to and beyond the ends of the slits 24, and then two slits 27, 28 are adjacent to the ends of the slits 26. In addition, it extends in the longitudinal direction, and each end thereof is substantially on the reference line of the slit 24. In this case, the ends of the slits 27 and 28 are connected to the slit 24 via broken lines 29 and 30 corresponding to kink lines 31 and 32 described below.

  The portions 33 and 34 of the base body 35 that can be bent along the kink lines 31 and 32 described in detail below are bounded by the slits 24, 25, 26, 27, and 28. A slit-shaped opening 36 is formed in each of the portions 33 and 34, and extends along the longitudinal direction of the material portion 19.

  Tongues 37 and 38 of the base body 35 having tabs 39 and 40 formed at the ends are further formed by the slits 22, 23 and 24.

  The base 35 of the material part 19 is divided into two longitudinal parts 41 and 42 by slits 20 to 28, and the longitudinal part can be separated perpendicularly to the longitudinal direction of the material part 19 as shown in FIG. Are connected to each other in a separated state via connecting elements 43 that are formed integrally with the longitudinal portions 41 and 42 and bridge the spaces between the longitudinal portions 41 and 42, respectively. As can be appreciated from FIG. 4, the opening bounded by the longitudinal edges 45, 46 of the material part 19 by the separation of the two longitudinal parts and the additional folding along the kink lines 29, 30 of the parts 33, 34. A portion 44 is formed between the longitudinal portions 41, 42.

  In this regard, in each case, the first portion 47 of the edge portions 45, 46 is formed by the bent portions 33, 34, while the second portion 48 of the edge portions 45, 46 adjacent thereto is folded. It is formed by tongues 37 and 38 which are not bent. In this respect, the bent portions 33 and 34 are in contact with the adjacent portions 49 and 50 of the base 35 shown by the hatched area in FIG. The adjacent portions 51 and 52 are further formed by the end portions of the tongue portions 37 and 38, and the double-layer region 53 of the base body 35 together with the bent portions 33 and 34 after the portions 33 and 34 are bent like the adjacent portions 49 and 50. , 54 are formed.

  The bent portions 33 and 34 are fixedly connected to the adjacent portions 49 to 52 via connecting means 55 and 56 in the double layer regions 53 and 54, respectively. In this respect, the connecting means 55 is shown as an example of a rivet connecting portion, but may be formed as other appropriate connecting means already mentioned at the beginning. As an example of FIG. 4, the connecting means 56 is formed by a slit-shaped opening 36 and tabs 39 and 40 of the tongue-shaped portions 37 and 38. Therefore, as can be recognized from FIG. 4, the tabs 39 and 40 are bent and pushed out through the slit-shaped opening 36.

  FIG. 5 shows a C-shaped upright portion 57 made from the material portion 35 of FIGS. The upright portion 57 includes a plurality of openings 44 through which the electric wire 18 or other supply line can pass. The edge portion 45 of the opening 44 where the electric wire 18 is hooked is formed by bending the portion 34 so that only the region 58 shown on the right in FIG. 5 is a rounded edge portion. When leaning on this area, the passed wire 18 may be damaged without additional protective means.

  In order to avoid such damage, a curved portion 63 such as a flange is provided on the remaining portion of the edge 45 as shown in the drawing of the opening 44 in FIG.

  Additionally or optionally, a cover element 59 is provided at the edge 45, as shown in the central opening diagram of FIG. The cover element 59 has, for example, the shape of a sleeve having a longitudinal slit shown in FIG. In this case, the cover element 59 is simply inserted into the edge 45 and is held by a corresponding clamping effect or is further pinched or compressed. Since the upper side of the cover element 59 is formed in a round shape, damage to the electric wire 18 is prevented.

  The cover elements can have different shapes, for example formed as the hook-shaped cover element 60 of FIGS. In this regard, additional fastening of the cover element 60 to the base body 35, for example by either an extended downwardly projecting part 61 of the cover element 60, rivet fastening or a connecting part of the kind mentioned at the beginning. Is possible.

  As shown in the lower part of FIG. 5, the opening 44 can also be covered at its entire edge with a corresponding cover element 62. Thus, the cover element 62 is generally closed and forms an eyelet that also protects the edge 45 and the edge of the opening 44 adjacent to the edge 45, similar to the cover elements 59, 60, respectively.

  In contrast to the rectangle shown in FIG. 5, the cover element or eyelet may have a rounded area so that a round internal contour corresponding essentially to the opening can be achieved. In this way, for example, a circular shape, an elliptical shape, an egg shape, or an angular shape having round corners is realized. In this respect, the opening itself can already have a corresponding round shape. On the other hand, the opening has an angular shape shown as an example in FIG. 5 and is formed only in a cover element corresponding to the opening, that is, an eyelet, for example, in a region between the corners. In comparison, it is possible to have a round inner contour with a greater wall thickness at the corners.

  FIG. 10 shows another embodiment of the present invention in which the cutting pattern of FIG. 3 is modified. For the sake of simplicity, only the differences from the embodiment of FIGS. In this regard, the same or similar elements in FIGS. 10 to 13 as those in FIGS.

  In FIG. 10, the slits 64 are in contact with the slits 21 and extend in the transverse direction with respect to the longitudinal direction of the material part 19 to the center line 65 of the material part 19, that is, the upper and lower parts of the material part 19. It extends to the center of the cutting pattern formed by the slits 20 and 21 extending diagonally. In this regard, one of the slits 64 extends from the slit 21 and ends on one side of the center line 65, and the other slit 64 starts from the slit 21 and extends toward the center line 65. It extends to terminate on the opposite side of 65.

  Adjacent to the slits 64 are each slit 66 that runs along the center line 65 and then adjoins a further slit 67 that extends to the opposite side of the slit 64 and extends parallel to the slit 64. Each slit 68 extending perpendicularly to each slit 67 is formed at the end of the slit 67 and extends parallel to each other and in parallel to the longitudinal direction of the material part 19. The centers of the two slits 68 are connected to each other through a slit 69 extending in parallel with the slit 67. Further, the slits 68 extend beyond the slits 67 and terminate at diagonally extending slits 70 connected to each other via kink lines 71 indicated by broken lines. Similarly, the end of the slit 67 is connected to the slit 68 via a kink line 72 indicated by a broken line.

  As can be recognized from FIG. 10, the slit 73 that extends diagonally and forms a triangular hole between the slits 68, 68, 73 corresponds to the slit 70 that extends diagonally. Formed between. Both diagonally extending slits 70 and diagonally extending slits 73 are optionally provided to prevent sharp corners from being formed in the resulting compartment elements. These slits may generally be omitted. In order to avoid sharp corners, the slits 70, 73 may be replaced by curved slits, for example forming essentially round corners.

  A first portion 75 adjacent to the kink lines 71, 72 and the second portion 76 bounded between the slits 68, 70 is formed between the slits 68, 69 and the kink line 72. Further, a third portion 77 is formed between the slits 66, 67, 68, 70 and the kink line 71.

  As already described with reference to FIG. 4, after the cutting pattern shown in FIG. 10 is introduced, the two longitudinal portions 41 and 42 of the base body 35 are separated. Thereby, as shown in FIG. 11, an interval is generated between the longitudinal portions 41 and 42, and they are bridged by the connecting element 43.

  Subsequently, each of the portions 75 is bent along the kink line 72, thereby forming an opening 78 shown in FIG.

  In a further step, the part 75 which has already been folded once is folded again along the kink line 71 together with the parts 76, 77 which are folded for the first time, so that the opening 78 has the final dimensions as shown in FIG. Become. The bent portions 75, 76, and 77 form double-layer or triple-layer regions 81, 82, and 83 together with adjacent portions 79 and 80 (see FIG. 10) of the base 35, and the bent portions 75, 76 and 77 are connected to the adjacent portions 79 and 80 by the connecting means 84. In this regard, the connecting means 84 can be formed in various ways already detailed within the framework of the present invention.

  In this embodiment, not only one part but also two parts 85 and 86 at the edges 87 and 88 that bound the longitudinal opening 78 of the material part are connected to the kink line 71 when the parts 76 and 77 are folded. The kink edges formed along are directly formed to be rounded edges. Thus, cover elements or eyelets for the edges 87, 88 are not necessarily required. In general, however, the cover elements and eyelets already mentioned may additionally be used in this embodiment.
