DETAILED DESCRIPTION OF THE DRAWINGS
[0039] FIG. 1a shows a first specific exemplary embodiment of an integral sheet metal part fabricated out of a flat, final rolled product comprised of metal in a downstream punching process. This flat and integral sheet metal part is marked as punched part 7 below. In the subsequent bending process, chamfering the punched part 7 results in a connecting element 1, see FIG. 2a. As indicated in the above specification, the connecting element 1 according to the invention essentially consists of a flat, punched part 7, which is roughly square in shape, and rounded at the corners. In addition, two approximately V-cutouts 30, 31 or radii are formed with a square shape on the horizontal center line 32. Two punched sections 9, 10 are arranged on the horizontal center line 32, which start at the outer edge 23, 24 in the V-cutout 30, 31 and run in the direction of the center of the punched part 7. The two punched sections 9, 10 running on the same center line 32 are spaced apart from each other. The distance between the two punched sections 9, 10 forms a web width 11, which is characterized by bending lines 13, 14. A respective bending line 13, 14 is located at the end of the converging punched sections 9, 10. The two bending lines 13, 14 are arranged perpendicular to the two punched sections 9, 10 and parallel to the perpendicular center line 33. Four quadrants I-IV arise as flat parts 25, 26, 27, 28 between the punched sections 9, 10 and bending lines 13, 14. These flat parts 25, 26, 27, 28 are arranged as rectangular flat parts 25, 26, 27, 28 on the web 4, and spaced parallel apart from the center line 33. The longer side of the rectangular surface 25, 26, 27, 28 together with the bending line 13, 14 forms a shared edge, and is spaced parallel apart from the center line 33. The shorter side consists of the outer edge 40, 41 of the rectangular surface 25, 26, 27, 28, which comprise the length of the legs 5, 5.1, 6, 6.1 of the U-profiles 2, 3 and run perpendicular to the center line 33. Punched holes 15, 15.1, 16, 16.1, 17, 17.1, 18, 18.1 are arranged in these flat parts 25, 26, 27, 28, a respective two punched holes 15, 15.1, 16, 16.1, 17, 17.1, 18, 18.1 per flat part 25, 26, 27, 28. These punched holes 15, 15.1, 16, 16.1, 17, 17.1, 18, 18.1 are spaced parallel apart from the perpendicular center line 33 of the punched part 7. The parallel distance 34, 35 is formed by the two perpendicular center lines 36, 37, which run through a respective two flat parts 25, 28 and 26, 27 of quadrants II, II and I, IV. The punched holes 15, 15.1, 18, 18.1 arranged on the center line 36 correspond with the punched holes 16, 16.1, 17, 17.1 arranged on the center line 37. After the flat parts 25, 26 have been bent along the bending lines 13, 14, the punched holes 15, 15.1, 16, 16.1 are congruent, i.e., they now have a shared center line 48, see FIG. 2a and FIG. 3. The same also applies to the flat parts 27, 28 and their punched holes 17, 17.1, 18, 18.1, which also are congruent after bent around the bending lines 13, 14. The distance 38, 38.1 of the punched holes 15.1, 16.1, 17, 18 from the horizontal center line 32, and hence from the punched section 9, 10, measures roughly of the overall length of a flat part 25, 26, 27, 28, while the distance 39, 39.1 of the punched holes 15, 16, 17.1, 18.1 from the horizontal center line 32 corresponds to roughly of the overall length of a flat part 25, 26, 27, 28. The punched holes 15, 15.1, 18, 18.1 are arranged on the center line 36, and the punched holes 16, 16.1, 17, 17.1 are arranged on the center line 37 one over the other in a vertical direction.
[0040] A web 4 running from the outer edge 40 to the outer edge 41 arises between the two bending lines 13, 14, and forms a flat part 29. The web width 11 corresponds to the thickness of a wall component. This web 4 is arranged symmetrically around the center line 33, and is the shared web 4 of all four flat parts 25, 26, 27, 28, even though the flat parts 25, 26 are separated from the flat parts 27, 28 by a punched section 9, 10. In addition, the web 4 has a bead 12. The bead 12 corresponds to the shape of a channel-shaped recess 12. The channel-shaped recess 12 is arranged symmetrically to the perpendicular center line 33, and embossed on the front side 22 of the punched part 7. A corresponding elevation that conforms to the depression 12 forms on the rear side of the web 4. Therefore, the bead 12 progresses along the web 4, wherein the bead 12 has a length corresponding to roughly half the overall length of the punched part 7. As viewed from the horizontal center line 32, half the length of the bead 12 lies on the web section in quadrants I and II, while the other half of the bead 12 is arranged in the web section of quadrants III and IV. The connecting element 1 thus has a reinforced center web 4, from which four flat parts 25, 26, 27, 28 extend in opposite directions from each other.
[0041] The four flat parts 25, 26, 27, 28 together have eight stamped holes 15, 15.1, 16, 16.1, 17, 17.1, 18, 18.1, of which a respective two correspond with each other as a stamped hole pair. In other words, the stamped hole pair 15 and 16 and stamped hole pair 15.1 and 16.1 correspond with each other, and are hence congruent. The same holds true with respect to the stamped hole pairs 17 and 18 and stamped hole pairs 17.1 and 18.1. A respective stamped hole 16, 16.1, 17, 17.1 of a stamped hole pair 15, 16 and 15.1, 16.1 and 17, 18 and 17.1, 18.1 is advantageously provided with a depression 19, 19.1, 20, 20.1. The depression 20, 20.1 on the two stamped hole pairs 17, 17.1 is introduced on the rear side 21 of the flat part 27 of the stamped part 7, while the depression 19, 19.1 on the two stamped hole pairs 16, 16.1 is introduced on the front side 22 of the flat part 26 of the stamped part 7. The stamped holes 15, 16 are arranged on a center line 70, the stamped holes 15.1, 16.1 are arranged on a center line 71, the stamped holes 17, 18 are arranged on a center line 72, and the stamped holes 17.1, 18.1 are arranged on a center line 73, wherein the center lines 70, 71, 72, 73 are spaced parallel apart from the center line 32 and from the outer edge 40, 41, and are spaced a distance 38, 38.1, 39, 39.1 apart from the center line 32. This stamped part forms the basis for the connecting element 1 according to FIG. 2a. When manufacturing the connecting element 1 according to FIG. 2a, the four flat parts 25, 26, 27, 28 are all bent by the same angle 67 relative to the web 4, preferably by 90 degrees, into a U-profile 2, 3, so that the parallel distance between the legs 5, 5.1 and 6, 6.1 remains identical. A right bending angle 67 ensures that all legs 5, 5.1 and 6, 6.1 stand perpendicular to the shared web 4.
[0042] In addition, the punched part 7 forms the basis for a corner angle connecting element 1.1 according to FIG. 2b. When manufacturing a corner angle connecting element 1.1 according to FIG. 2b, all flat parts 25, 26, 27, 28 are bent by the same angle 68, not by a right bending angle 67 of 90 degrees, but instead only by an exemplary respective bending angle 68 of 67.5 degrees, resulting in an overall angle 66 of 135 degrees as the distance between the U-profiles 2, 3. The legs 5, 5.1 and 6, 6.1 are in turn spaced parallel apart, but no longer stand perpendicular to the shared web 4, but rather are arranged at an inclination to the latter. This changes the parallel distance between the legs 5, 5.1 and 6, 6.1, with the distance diminishing. The reduction in distance can be countered by expanding the web 4, which makes it possible to restore the required parallel distance between the legs 5, 5.1 and 6, 6.1, as shown on FIG. 2b. Identical designations on FIG. 1a are provided with the same reference numbers on FIGS. 1b, 2a, 2b, 2c, 3, 4a and 4b.
[0043] FIG. 1b schematically illustrates another specific exemplary embodiment of a flat punched part 7.1 for a corner angle connecting element 1.2. This second exemplary embodiment involves a workpiece comprised of a flat punched part 7.1, which is used in bending technology for manufacturing a corner angle connecting element 1.1. This punched part 7 forms the basis for the corner angle connecting element 1.2 according to FIG. 2b. The punched part 7.1 has three identical flat parts 25, 26, 27 with the accompanying quadrants I, II, III, as already known from FIG. 1a. For this reason, the description from FIG. 1a can here be drawn upon for describing FIG. 1b. These three flat parts 25, 26, 27 are provided with the corresponding punched holes 15, 15.1, 16, 16.1, 17, 17.1, and according to the first exemplary embodiment remain symmetrically arranged around the perpendicular center line 33. The difference between the punched part 7 used to fabricate the connecting element 1 and the punched part 7.1 used to fabricate the corner angle connecting element 1.1 is that the flat part 28 of quadrant IV has a different size. The change in size of the flat part 28 is equal to the change in size of the distance between the outer edge 23 and center line 33. Because of this differing size, the punched part 7.1 is asymmetrical in design. However, the asymmetry relates only to the difference between the flat part 27 and flat part 28 of quadrants III and IV, which remain arranged around the same center line 33, perpendicular thereto. With respect to the punched part 7, the length of the flat part 27 from the center line 33 up to the outer edge 24 is identical to the length of the flat part 28, which also runs from the center line 33 up to the outer edge 23. However, what is crucial is the distance 35 between the punched holes 17, 17.1 in quadrant III and the bending line 14 and the corresponding distance 34 between the punched holes 18, 18.1 in quadrant IV and the bending line 13.1. These two distances 34, 35 must be identical.
[0044] When manufacturing the corner angle connecting element 1.2 according to FIG. 2c, only the flat parts 25, 26 are bent by the same angle 67, preferably by 90 degrees, to yield a U-profile 2, while the flat parts 27, 28 are not bent by 90 degrees, but rather only by the angle 68, for example by 45 degrees, relative to the web 4 to yield a U-profile 3. This results in an overall angle 66 of 135 degrees between the two U-profiles 2, 3. The legs 5, 5.1 of the U-profile 2 stand perpendicular to the web 67 due to the right angle 67, while the legs 6, 6.1 are arranged at an inclination to the web 4 due to the other bending angle 68. However, the parallel distance between the legs 6, 6.1 of the U-profile 3 would diminish here as well. In order to offset this reduction, the invention proposes that the flat part 28 be elongated for the punched part 7.1. The elongation yields an intermediate web 4.1. The intermediate web 4.1 is hinged to the web 4 on the one hand, and to the leg 6.1 of the U-profile 3 on the other. The intermediate web 4.1 is bounded by the bending line 13 and bending line 13.1. The width 11.1 of the intermediate web 4.1 counteracts the reduction in the parallel distance between the legs 6, 6.1 in the bending process. The change in the parallel distance between the legs 6, 6.1 is influenced by the bending angle 66, see FIG. 2c, wherein the bending angle 66 indicates the distance between the U-profile 2 and U-profile 3. The angle 66 is an obtuse angle, which in turn is comprised of the two angles 67 and 68. The angle 67 forms the right angle between the web 4 and legs 5, 5.1 of the U-profile 2, while the angle 68 forms the acute angle between the web 4 and legs 6, 6.1 of the U-profile 3. The more acute the angle 68 gets, the wider the intermediate web 4.1 must become to continue ensuring the same required parallel distance between the legs 6, 6.1. The required distance between the legs 6, 6.1 of a U-profile 3 is determined by the wall thickness of a wall element 47. Even if the width of the intermediate web 11.1 increases, the clearance 34 between the bending line 13.1 and center line 36.1 that runs through the punched holes 18, 18.1 is held constant. This ensures that the punched holes 18, 18.1 correspond with the punched holes 17, 17.1 after the process of bending the flat parts 27, 28, and have a shared center line 73.
[0045] FIG. 1c shows another specific exemplary embodiment of a flat punched part 7.2 proceeding from FIG. 1a. In the ensuing bending process, the punched part 7.2 also yields a connecting element 1 according to FIG. 2d. A portion of the description for the flat punched part 7.2 can be derived from FIG. 1a. Corresponding reference numbers are analogously incorporated into FIG. 1c here as well. In other words, the web 4 and channel-shaped recess 12 arranged on the perpendicular center line 33 along with the two punched sections 9, 10 on the horizontal center line 32 are identical to the punched part 7 on FIG. 1a. Only the differences to FIG. 1a are here highlighted. This punched part 7.2 forms the basis for a connecting element 1 according to FIG. 2d. The punched part 7.2 has four identical flat parts 25, 26, 27, 28 with the accompanying quadrants I, II, II, IV, as already known from FIG. 1a. These flat parts 25, 26, 27, 28 are also bounded by the outer edges 23, 24, 40, 41, wherein the length of the outer edges 23, 24, 40, 41 determines the size of the flat parts 25, 26, 27, 28. In the punched part 7 in the exemplary embodiment according to FIG. 1a, the lengths of the outer edges 23, 24, 40, 41 are dimensioned in such a way as to yield roughly a square for the punched part 7. The lengths of the outer edges 40 to 24 or 41 to 23 have a ratio of roughly 1:1 to each other. The punched sections 9, 10 form four flat parts 25, 26, 27, 28 for the square, which form a rectangle, wherein the interior longitudinal sides of the rectangular flat parts 25, 26, 27, 28 correspond with the bending lines 13, 14, and the short outer edges 40, 41 (short longitudinal sides of the rectangular flat parts 25, 26, 27, 28) determine the length of a leg 5, 5.1, 6, 6.1. Short outer edges 40, 41 yield short legs 5, 5.1, 6, 6.1 for a connecting element 1, in which the fastening openings (punched holes 15, 15.1, 18, 18.1, 16, 16.1, 17, 17.1) are vertically arranged. In the present exemplary embodiment of the punched part 7.2, the lengths of the outer edges 40, 41 are dimensioned in such a way as to yield a rectangle for the punched part 7.2. The lengths of the outer edges 40 to 24 or 41 to 23 have a ratio of roughly 1.6:1 to each other. In other words, the outer edge 40, 41 is significantly longer in design than the outer edge 23, 24. This rectangle is again divided into four flat parts 25, 25, 26, 28, which in turn each form a rectangle, wherein the short longitudinal sides of the rectangular flat parts 25, 26, 27, 28 now correspond with the bending lines 13, 14, and the longer outer edges 40, 41 arranged perpendicular to the center line 33 form long legs 5, 5.1, 6, 6.1 for a connecting element 1, in which the fastening openings (punched holes 15, 15.1, 16, 16.1 and punched holes 17, 17.1, 18, 18.1) are arranged horizontally on a center line 74, 75. The number of punched holes in quadrants I, II, III, IV of the punched part 7.2 is identical with the embodiment of the punched part 7, with only the arrangement having been changed to satisfy the requirements during assembly in the building trade. The distance 34, 35 between the punched holes 15, 18 and 16, 17 in punched part 7.2 and the bending line 13, 14 is approximately the same as the distance 34, 35, between the punched holes 15, 15.1, 18, 18.1 and 16, 16.1, 17, 17.1 in punched part 7 according to FIG. 1a, wherein the distance 78, 79 between the punched holes 15.1, 18.1 and 16.1, 17.1 and the bending line 13, 14 is significantly greater, and produced by the distance 34, 35 from the bending line 13, 14 and the distance 76, 77 between the punched holes 15, 15.1 and 16, 16.1 as well as 17, 17.1 and 18, 18.1.
[0046] Based on the punched part 7 according to FIG. 1a, FIG. 2a schematically illustrates a connecting element 1 according to the invention after the bending process. For this reason, the reference numbers listed on FIG. 1a are here used analogously. The two flat parts 25, 26 of quadrants I, II are bent toward the back along the bending lines 13, 14 by a respective 90 degrees and form the legs 5, 5.1 of the U-shaped profile 2, wherein the legs 5, 5.1 largely run parallel to each other. The web 4 with its channel-shaped recess 12 remains in its position, thereby yielding a U-shaped profile 2. The two punched hole pairs 15, 16 and 15.1, 16.1 stand perpendicular to each other, spaced apart only by the web width 11, and now have a shared center line 48. The two punched lines 9, 10 according to FIG. 1a now form an outer edge 42, spaced parallel apart from the outer edge 40. Analogously thereto, the two flat parts 27, 28 of quadrants III, IV were also bent toward the front along the bending lines 13, 14 by 90 degrees, and now form the legs 6, 6.1 of the U-shaped profile 3. These legs 6, 6.1 also run largely parallel to each other. The legs 6, 6.1 of the U-shaped profile 3 run in the direction opposite the offset, opposing legs 5, 5.1 of the U-profile 2. This means that the U-shaped profile 2 bent toward the back is spaced apart from the U-shaped profile 3 bent toward the front by 180 degrees. The openings of the U-profiles 2, 3 thus face in the opposite direction. The two punched hole pairs 17, 18 and 17.1, 18.1 now also stand perpendicular to each other, spaced apart only by the web width 11, and have a shared center line 48. Here as well, the two punched lines 9, 10 according to FIG. 1a form an outer edge 43, and run spaced parallel apart to the outer edge 41. The front side 22 of the flat part 26 of quadrant II together with the rear side 21 of the flat part 27 now form a shared front surface 44, which corresponds to the control side of the connecting element 1. The shared front surface 44 of the control side is reached via the used bending angle 67. All flat parts 25, 26, 27, 28 are bent by the same angle 67, preferably by 90 degrees, to yield a U-profile 2, 3, as a result of which the legs 5, 5.1, 6, 6.1 form U-shaped profiles 2, 3. A right bending angle 67 ensures that all legs 5, 5.1 and 6, 6.1 stand perpendicular to the shared web 4. An elongated angle 69 arises between the two U-shaped profiles 2, 3, and consists of the two right angles 67, so that the shared front surface 44 of the control side lies in one plane. Depressions 19, 19.1, 20, 20.1 are introduced into the punched holes 16, 16.1, 17, 17.1 on the control side of a connecting element 1 in order to introduce pop rivets 45. A punched hole pair 17.1, 18.1 as a cutout X from FIG. 2a is shown in greater detail on FIG. 3.
[0047] Based on the punched part 7 according to FIG. 1a, FIG. 2b presents a schematic illustration of a corner angle connecting element 1.1 according to the invention after the bending process. The reference numbers listed on FIG. 1a are here analogously used. The two flat parts 25, 26 of quadrants I, II are bent toward the back by a respective 67.5 degrees along the bending lines 13, 14, and form the legs 5, 5.1 of the U-shaped profile 2, wherein the legs 5, 5.1 run largely parallel to each other. The web 4 with its channel-shaped recess 12 remains in its position, thereby yielding an approximately U-shaped profile 2. The two punched hole pairs 15, 16 and 15.1, 16.1 now stand perpendicular to each other, and are only spaced apart by the web width 11. The two punched lines 9, 10 according to FIG. 1a now form an outer edge 42, and run spaced parallel apart from the outer edge 40. Analogously thereto, the two flat parts 27, 28 of quadrants III, IV were bent toward the front by 67.5 degrees, also along the bending lines, and now form the legs 6, 6.1 of the U-shaped profile 3. These legs 6, 6.1 also run largely parallel to each other. As opposed to the flat parts 25, 26 of quadrants I, II or to the legs 5, 5.1, however, the legs 6, 6.1 of the U-shaped profile 3 face in roughly the opposite direction. A U-shaped profile 3 is formed here as well, and faces in approximately the opposite direction, angled by 135 degrees to the U-shaped profile 2. The web 4 with its depression 12 remains in its position between the legs 5, 5.1, 6, 6.1. However, all legs 5, 5.1, 6, 6.1 are arranged inclined to the web 4, since they were chamfered not at an angle 67 of 90 degrees, but at an angle 68 of 67.5 degrees. The two punched hole pairs 17, 18 and 17.1, 18.1 now also stand perpendicular to each other, spaced apart only by the web width 11. Here as well, the two punched lines 9, 10 according to FIG. 1a now form an outer edge 43, and run spaced parallel apart from the outer edge 41. The front side 22 of the flat part 26 of quadrant II now forms a shared front side 44 with the rear side 21 of the flat part 27. The shared front side 44 corresponds to the control side of the connecting element 1.1. The shared front side 44 of the control side is achieved by the used bending angles 68. All flat parts 25, 26, 27, 28 are bent by the same angle 68, preferably by 67.5 degrees, to yield a U-profile 2, 3, as a result of which the legs 5, 5.1, 6, 6.1 form U-shaped profiles 2, 3. An acute bending angle 68 ensures that all legs 5, 5.1 and 6, 6.1 run at an inclination to the shared web 4. An obtuse angle 66 arises on the front side 22 between the two U-shaped profiles 2, 3, and is comprised of the two acute angles 68. The shared control side of the legs 5, 6 remains, although the U-profiles 2, 3 are angled relative to each other, still on the front side 44 of a corner angle connecting element 1.1. In addition, depressions 19, 19.1, 20, 20.1 for introducing pop rivets 45 according to the following FIG. 3 are provided in the punched holes 16, 16.1, 17, 17.1 on the control side of a corner angle connecting element 1.1.
[0048] Based on the punched part 7.1 according to FIG. 1b, FIG. 2c presents a schematic illustration of a corner angle connecting element 1.2 according to the invention after the bending process. The reference numbers listed on FIG. 1b are here analogously used. The two flat parts 25, 26 of quadrants I, II are bent toward the back by a respective 90 degrees along the bending lines 13, 14, and form the legs 5, 5.1 of the U-shaped profile 2, wherein the legs 5, 5.1 run largely parallel to each other. The web 4 with its channel-shaped recess 12 remains in its position, thereby yielding a U-shaped profile 2. The two punched hole pairs 15, 16 and 15.1, 16.1 now stand perpendicular to each other, spaced apart only by the web width 11, and now have a shared center line 48. The two punched lines 9, 10 according to FIG. 1b now form an outer edge 42, and run spaced parallel apart from the outer edge 40. Analogously thereto, the flat part 27 of quadrant III was bent toward the front, but only by 45 degrees, also along the bending lines, and now forms the legs 6 of a U-shaped profile 3. Contrary to the indications on FIG. 2a, the flat part 28 is not bent around the bending line 13 to a leg 6.1 to obtain a U-profile, but now the intermediate web 4.1 instead. The intermediate web 4.1 laterally adjoins the web 4 directly, and is bent toward the front by 90 degrees at the bending line 13. As was the case with the leg 6.1 from FIG. 2a, the intermediate web 4.1 is bent toward the front by 90 degrees, and thus stands perpendicular to the web 4. The flat part 28, which is identical to the other flat parts 28 from FIGS. 1a, 2a, 2b, is now bent toward the front by 45 degrees at the bending line 13.1, just as the flat part 27. The angled flat part 28 now forms the leg 6.1. As a consequence, the legs 6 and 6.1 run in the same direction, and are largely spaced parallel apart from each other, wherein both legs 6, 6.1 now form a U-shaped profile 3. The web 4 with its channel-like depression 12 remains unchanged in its position between the legs 5, 5.1, 6, 6.1.
[0049] The legs 5, 5.1 of quadrants I, II stand perpendicular to the web 4, while the legs 6, 6.1 of quadrants III, IV face in a direction angled away from the web 4. In other words, the U-profile 2 is perpendicular to the web 4, and the U-profile 3 is arranged at a specific angle to the web 4. The two offset and opposing U-profiles 2, 3 face roughly in the opposite direction. A U-shaped profile is formed here as well, which faces in approximately the opposite direction at an angle 66 of 135 degrees to the U-shaped profile 2. The two punched hole pairs 17, 18 and 17.1, 18.1 now also stand perpendicular to each other, spaced apart only by the web width 11. The two punched lines 9, 10 from FIG. 1b now form an outer edge 43, and run spaced parallel apart from the outer edge 41. The front side 22 of the flat part 26 of quadrant II now forms a shared front side 44 with the rear side 21 of the flat part 27 of quadrant III. The front side 44 corresponds to the control side of the connecting element 1.2. The shared front side 44 of the control side is achieved by the used bending angles 67 and 68. The two flat parts 25, 26 are bent at the right angle 67, and the two flat parts 27, 28 are bent at an acute angle 68 of preferably 45 degrees to yield a U-profile 2, 3, as a result of which the 5, 5.1, 6, 6.1 form U-shaped profiles 2, 3. A right bending angle 67 between the legs 5, 5.1 and web 4 ensures that the legs 5, 5.1 are arranged perpendicular to the web 4, while an acute bending angle 68 between the leg 6 and web 4 ensures that the leg 6 runs at an inclination to the shared web 4. The acute bending angle 68.1 between the leg 6.1 and intermediate web 4.1 ensures that the leg 6.1 runs parallel to the leg 6. The bending angle 67 and bending angle 68 are congruent to the bending angles c 67.1 and 68.1.
[0050] An obtuse angle 66 comprised of a right angle 67 and an acute angle 68 arises between the two U-shaped profiles 2, 3 on the front side 44. The shared control side of the legs 5, 6 remains, although the U-profiles 2, 3 are angled relative to each other, still on the front side 44 of a corner angle connecting element 1.2. Depressions 19, 19.1, 20, 20.1 for introducing pop rivets 45 according to the following FIG. 3 are provided in the punched holes 16, 16.1, 17, 17.1 on the control side of a corner angle connecting element 1.2.
[0051] Based on the punched part 7.1 according to FIG. 1c, FIG. 2d presents a schematic illustration of a connecting element 1 according to the invention after the bending process. The reference numbers listed on FIG. 1c are here analogously used because the technical features are identical. Only the changes relating to the connecting element 1 from FIG. 2a are pointed out here. The connecting element 1 from FIG. 2a has short legs 5, 5.1, 6, 6.1 for the U-profiles 2, 3. The fastening holes (punched holes 15, 15.1, 18, 18.1, 16, 16.1, 17, 17.1) are vertically arranged on the center lines 36, 37, which are spaced parallel apart from the center line 33. By contrast, the connecting element 1 according to this FIG. 2d has long legs 5, 5.1, 6, 6.1 for the U-profiles 2, 3. In the long legs 5, 5.1, 6, 6.1 of the U-profiles 2, 3, the fastening holes (punched holes 15, 15.1, 16, 16.1 and 17, 17.1, 18, 18.1) are arranged next to each other and horizontally to the perpendicular center line 33 and to the web 4. The number of fastening holes in a leg 5, 5.1, 6, 6.1 in a horizontal direction depends on the length of the legs 5, 5.1, 6, 6.1, and can thus be adjusted to the requirements. The same holds true for the connecting element 1 according to FIG. 2a. The number of fastening holes are here arranged one over the other and vertically to the perpendicular center line 33 and to the web 4. The number of fastening holes depends on the length of the legs 5, 5.1, 6, 6.1 in a vertical direction, with an adjustment to the requirements during assembly being possible here as well.
[0052] FIG. 3 shows a connecting element 1 in cross section. Involved here is the cutout X from FIG. 2a. The reference numbers listed on FIGS. 1a and 2a are here used analogously. The cutout X indicates an embodiment for a punched hole pair 17.1, 18.1 in the connecting element 1, which is representative for the other punched hole pairs 15, 16 and 15.1, 16.1 and 17, 18 according to FIGS. 1a, 1b, 2a, 2b, 2c. FIG. 3 further shows the U-shaped profile 3, with a wall component 47 inserted between its flat parts 27, 28 for fastening a connecting element 1 to the latter, or the connecting element 1 is slipped onto a wall component 47. The depression 20.1 arranged in the flat part 27 or in the leg 6 around the punched hole 17.1 is located on the front side 44 of the connecting element 1. The depression 20.1 has an angle 50 that corresponds to the angle of the pop rivet head 51. The punched hole 18.1 spaced apart by the thickness of the wall component 47 is located in the flat part 28 on the same center line 48 of the punched hole 17.1 with the depression 20.1. The wall component 47 also has a borehole 49, wherein the size of the borehole 49 is adjusted to the diameter of the pop rivet 45.
[0053] In a first embodiment, the punched hole 17.1 has not only a depression 20.1 on the front side 44, but also a defined inclination 54 on the interior side 54.1 of the leg 6 created by embossing the depression 20.1. The inclination 54 forms an elevation 54.2 on the interior side 54.1 of the leg 6. This elevation 54.2 serves as a first attachment for the connecting element 1 while slipping the connecting element 1 onto a wall element 7. The elevation 54.2 thus forms a clamping means, which prevents the connecting element 1 from being able to fall off a narrow side 55, 56 while handling the wall components 47, see FIG. 4a.
[0054] In another embodiment, the elevation 54.2 can also consist of a defined ridge 45 on the sides facing the wall component 47. A depression 20.1 and a defined ridge 46 are shown based on the example of the punched hole 17.1, as representative for the other punched holes 16, 16.1, 17. The ridge 46 is provided with a tooth system (not shown), so that the ridge 46 acts like a latching means in relation to the wall component 47. The tooth system latches or claws its way into the surface of the wall component 47, as a result of which the connecting element 1 has a retaining effect relative to the wall component 47. However, other latching means are also conceivable. In the present example, a pop rivet 45 is located in the punched holes 17.1, 18.1 and the borehole 49. The job of the pop rivet 45 is to join the two legs 6, 6.1 of the U-shaped profile 3 of a connecting element 1 with a wall component 47. A known tool (setting tool) is used for establishing the connection, and need not be described in any more detail. When assembling a wall component using a connecting element, for example during roof extensions, a pull-through rivet with a thread or known screws, e.g., drywall screws (not shown), can be used instead of the pop rivet for fastening the connecting element, if a roof beam or rafter is located at the connecting point. During the general use of drywall screws in place of pop rivets, the diameters for the punched holes 15, 15.1, 16, 16.1, 17, 17.1, 18, 18.1 and depressions 19, 19.1, 20, 20.1 are adjusted according to the dimensions of the screws.
[0055] FIGS. 4a and 4b present a schematic illustration of a corner angle connecting element 1.1 or 1.2 according to the invention in use, for example during the roof extension 53 of a building 52. This case can involve a corner angle connecting element 1.1 according to FIG. 2b or a corner angle connecting element 1.2 according to FIG. 2c. Therefore, corresponding designations from FIGS. 1b, 2b and 2c are provided with the same reference numbers. An integral, flat punched part 7, 7.1 according to FIG. 1a, 1 b is used as the basis for the corner angle connecting element 1.1, 1.2, preferably a punched part 7.1 according to FIG. 1b. As indicated in the descriptions above, the connecting element 1.1, 1.2 according to the invention essentially consists of a flat punched part 7, 7.1, which has a square or approximately square shape, and rounded corners. As described above, this corner angle connecting element 1.1, 1.2 is bent apart at the punched lines 9, 10 and angled along the bending lines 13, 13.1, 14, as a result of which a respective two pairs of legs 5, 5.1 and 6, 6.1 are turned into U-shaped profiles 2, 3.
[0056] According to FIG. 4a and FIG. 4b, such a corner angle connecting element 1.1, 1.2 is used for connecting panel-shaped components for interior construction, e.g., for covering walls, ceilings and/or fabricating lightweight walls. During the assembly of such wall components 47, these corner angle connecting elements 1 are preferably used in roof extensions 53 or anywhere that the narrow sides 55, 56 of the wall components 47 are not perpendicular, but rather abut against each other at a specific angle 58, the roof pitch angle , just as in the case of roof pitches 57.
[0057] The roof pitch 57 is the steepness of a roof surface 59, which is indicated as an angle in degrees, the so-called roof pitch angle 58. The roof pitch angle 58 as a rule measures between 20 degrees and 80 degrees, preferably 45 degrees. As a rule, a roof extension 53 with wall components 47 so as to achieve a traversable room starts with the assembly of perpendicular wall components 47.1. Owing to the roof incline or roof pitch 57, these wall components 47.1 are then adjoined by wall components 47.2 whose narrow sides 56 abut against the narrow sides 55 of the perpendicularly arranged wall components 47.1 at a roof pitch angle 58. The wall components 47.2 arranged on the roof incline 57 are then laid in the direction of the roof ridge, vertically, until a horizontal ceiling 61 comprised of wall components 47.3 can be put in. In other words, an angle 63 once again arises at the location where the narrow sides 55 of the wall components 47.2 arranged on the roof incline 57 come to abut against the narrow sides 56 of the wall components 47.3 arranged on the horizontal ceiling 61. This angle 63 between the roof incline 57 and horizontal ceiling 61 corresponds with the angle 62 between the perpendicular wall components 47.1 and roof incline 57. Since these angles 62 and 63 are congruent or identical in size, the same corner angle connecting elements 1.1 can be used at both seams 64, 65 of the adjoining wall components 47.1, 47.2, 47.3. The craftsman decides how many corner angle connecting elements 1.1 are arranged on the narrow sides 55, 56 for connecting wall components 47.1, 47.2, 47.3. Depending on the length and width of a wall component 47, several corner angle connecting elements 1.1, 1.2 are preferably used so as to increase the strength at the seams 55, 56 and avoid expansion cracks. Because the roof inclines 57 vary, corresponding corner angle connecting elements 1.1, 1.2 with different angles 66 between the legs 5, 6 of the U-shaped profiles 2, 3 are kept available. On FIGS. 4a and 4b, the angle 66 preferably measures 135 degrees for the corner angle connecting elements 1.1, 1.2, which corresponds to the angle 62, 63. These 135 degree corner angle connecting elements 1.1, 1.2 can have varying web widths 11. The web widths 11 are made up of the web 11 or the web 11 with the intermediate web 11.1, so that wall components 47 with different thicknesses can be accommodated, or varying distances between the legs 5, 5.1, 6, 6.1 of the U-profiles 2, 3 can be kept available.
