Definitions

  • the present invention relates to a construction profile in the form of a T-profile rail for supporting plate-shaped elements for the laying-in of ceiling slabs for grid ceilings, and to a method and an apparatus for producing such a construction profile.
  • Construction profiles of this type are produced in many cases from a metallic, elongated body, such as a metal sheet.
  • the generation is often done in the so-called online method, i. a correspondingly elongated material web is subjected during the forward movement of the material web in the longitudinal direction of a plurality of forming steps in order to achieve the final profile shape. It is particularly important that high processing speeds of up to 150 m / min are achieved in order to achieve the highest possible throughput.
  • a T-profile rail according to the invention comprises the features of claim 1.
  • the method according to the invention comprises the features of claim 6.
  • the device according to the invention comprises the features of claim 10.
  • the openings in the longitudinal areas for example, not by material wastes punching, but generated by a flaring process.
  • a profile recess or elevation with lateral guide surfaces is thereby formed, especially in the middle area.
  • the profile recess may be formed as a guide groove and / or the profile elevation as the rear region of a guide groove.
  • a guide groove can be embossed in a simple manner, which can be done directly in the online process.
  • the profile recess or increase can thus be generated directly during the longitudinal movement of the material web.
  • the slot-shaped openings can be advantageously produced during the longitudinal movement of the material web, in order to ensure in this way a single-stage on-line production process.
  • the longitudinal regions comprise at least two partial longitudinal regions arranged side by side in the longitudinal direction, which are integrally connected to one another by folded, web-shaped sections in order to form the widened openings.
  • the openings can thus be produced by folding over these web-shaped sections, which in each case connect two partial longitudinal areas of the respective longitudinal area in one piece.
  • the openings are produced in this case by a so-called folding process.
  • the T-profile rail comprises a double-walled region with two surface sections, wherein the widened openings are formed in the two surface sections of the double-walled region.
  • the longitudinal areas become this after the widening of the openings bent over the central region, wherein the central region is reshaped so that the longitudinal regions form the double-walled region.
  • an outer region which adjoins the respective longitudinal region and which in particular can be formed without openings, is in each case bent over the respective longitudinal region.
  • the resulting construction profile then comprises correspondingly bent outer regions, in which, in particular, no openings are formed.
  • the construction profile is designed as a T-profile rail, for supporting plate-shaped elements for insert mounting of ceiling panels for grid ceilings.
  • the middle region forms an upper flange, the double-walled region a web and the outer regions a lower flange of the T-profile rail. Since the web is double-walled, it is not disadvantageous for the stability that the openings are formed in this area.
  • corrugations may preferably be formed in the longitudinal regions. These can extend in particular in the areas between the openings and thus extend transversely to the longitudinal extent of the longitudinal areas.
  • the beads can extend over the entire width of the longitudinal areas or only over a part thereof.
  • a plurality of beads in the edge regions of the longitudinal regions are connected to each other via further beads extending in the longitudinal direction.
  • the beads may form a conductor pattern or one or more, in particular, intermeshing comb structures.
  • these can be embossed into the longitudinal regions, in particular in the online process.
  • the beads are not directly embossed, but surrounding the beads material areas of the longitudinal areas be embossed, so that the non-embossed areas ultimately form protruding beads.
  • the beads can be advantageously formed after the production of the openings.
  • the openings in this case form compensating sections, which essentially absorb material stresses occurring due to the embossing process, so that a waviness or bulging of the material web caused by the embossing process outside the embossings is prevented or at least minimized. This is especially true when the openings are at least partially or completely disposed within the imprints.
  • the maximum depth of the embossings may preferably be at least approximately 2 times, in particular at least approximately 3 times, preferably at least approximately 5 times, the material thickness of the starting material of the material web. Even with these unusually deep embossing unwanted waviness or bulging of the web is avoided and at the same time achieved a stiffening of the material through the openings.
  • Fig. 1 shows a frame structure 1, which consists of a plurality of parallel and perpendicular thereto extending rails 2.
  • the profiled rails 2 have a T-shaped cross-section, with an elongated web 3, and a subsequent at its lower longitudinal edge lower flange 4.
  • the lower flange 4 consists of two bends of the web 3 each outwardly, formed by the two lower flange sections 5, 6 be, the support surfaces for plate-shaped elements 7, for example, form ceiling panels.
  • the rails 2 have on each of their upper longitudinal side a top flange 8, which is designed as a hollow profile and for coupling the rails 2 on suspension elements 9, 10 is used.
  • the web 3 forms a double-walled area 11 with two surface portions 12 of the rail 2, in each of which a plurality of openings 13 are formed.
  • the profiled rail 2 is formed symmetrically along a longitudinally extending center plane coinciding with the web 3 and comprises a main body 14 which has a longitudinally extending central region 15, longitudinal regions 16 extending on both sides of the central region 15 and longitudinal regions 16 each subsequent, also extending in the longitudinal direction outer regions 17 includes.
  • the two longitudinal regions 16 abut each other and form the double-walled region 11 and thus the web 3.
  • the two outer regions 17 are each bent over the longitudinal regions 16 by 90 ° and form the two Untergurtabroughe 5, 6th
  • a profiled recess 18 formed as a guide groove is formed, which extends over the entire length of the profiled rail 2.
  • the profile recess has two lateral guide surfaces 19, which are designed for lateral guidance in the production of the rail 2, as will be explained in more detail below.
  • the openings 13 formed in the longitudinal regions 16 are arranged alternately.
  • the Longitudinal portions 16 each divided into two longitudinally juxtaposed partial longitudinal regions 21, 22, which are integrally connected to each other by folded, web-shaped portions 23 to form the openings 13.
  • the openings 13 are formed as widened openings, as will also be explained in more detail below. While the openings 13 in the two longitudinal regions 16 are each arranged so that they are aligned with one another, it is also possible in principle for the openings 13 in the one longitudinal region 16 to be offset relative to the openings 13 in the other longitudinal region 16, so that the openings 13 are each partially or completely covered by the material of the respective opposite longitudinal region 16.
  • Transverse beads 41 are formed in each of the longitudinal regions 16 and extend into the regions between the openings 13.
  • the cross beads 41 are connected at their outer ends in each case with longitudinal beads 42, so that two comb-like structures are formed.
  • This transverse and longitudinal beads 41, 42 can either be embossed directly or the material regions 43 lying between the transverse and longitudinal beads 41, 42 can be embossed, so that the transverse and longitudinal beads 41, 42 remain as elevations. In this case, it is achieved that the material stresses occurring during the embossing process are absorbed by the openings 13 located within the embossed regions, so that undesirable waviness or bulging of the longitudinal regions 16 is avoided.
  • Fig. 3 shows a plan view of an elongated material web 24, which is moved to produce the rail 2 along its longitudinal direction according to an arrow 25.
  • the material web 24 is formed as a flat material web, wherein in Fig. 3 are indicated by dashed lines 26, 27 each bending edges along which each of the outer Areas 17 relative to the longitudinal portions 16 and the longitudinal portions 16 are bent relative to the central region 15 to ultimately the rail 2 according to Fig. 2 to create.
  • the openings 13 are not yet shown in their expanded form in the longitudinal regions 16, but there are only slot-shaped openings 26 present, which are introduced for example by a laser cutting method, a Hubstanz compiler or a rotary cutting process.
  • the material web 24 is unwound in a continuous process, for example by a roller 29 and fed via guide rollers 30 a profiling unit 31. In this profile recess 18 is impressed continuously, as in Fig. 4 indicated at the position 32. In a further forward movement in the longitudinal direction according to the arrow 25, the material web 24 is fed to a cutting unit 33, in which the slot-shaped openings 28 are generated. Thereafter, the web of an optional embossing unit 44 for generating the transverse and longitudinal beads 41, 42 are supplied.
  • the material web 24 is fed to a widening unit 34.
  • guide portions 35, 36 are provided, which cooperate with the profile recess 18 so that a movement of the central region 15 of the material web 24 is prevented transversely to the longitudinal direction and substantially in the plane of the web 24.
  • the guide section 35 engages in the profile recess 18 from above, while the guide section 36 engages around the corresponding profile elevation on the other side of the material web 24.
  • the guide portion 35 abuts against the guide surfaces 19 of the profile recess 18 and thus prevents movement transversely to the longitudinal extent of the material web 24.
  • the guide portion 36 abuts the corresponding outer surfaces of the profile elevation, also to avoid a transverse displacement.
  • each guide section can be provided instead of two such guide sections 35, 36.
  • On the opposite surface of the material web may be provided as needed, another suitable support or guide surface for the web 24.
  • the profile recess can also be introduced from below into the material web 24, so that a corresponding profile elevation protrudes upward from the material web 24.
  • the material web 24 guided in this way is widened in the widening unit 34 by gripping the two outer longitudinal edges 37, 38 of the material web 24 and pulling them apart in a direction perpendicular to the longitudinal extension and essentially in the plane of the material web 24 in accordance with arrows 39, 40. Since the material web 24 is fixed in the transverse direction via the profiled recess 18 and the guide sections 35, 36, the longitudinal areas 16 lying on both sides of the central area 15 are acted upon in identical manner by corresponding winding forces, whereby the slot-shaped openings 28 are uniformly widened in both longitudinal areas until the in Fig. 2 illustrated expanded openings 13 are formed. By fixing the central region 15 via the profile recess 18 and The guide portions 35, 36 is thereby ensured that the openings 13 are widened uniformly in both longitudinal regions 16.
  • the expanded material web in a forming station, not shown, to the in Fig. 2 represented profiled rail 2 are deformed by the outer regions 17 along the dashed line 26 with respect to the longitudinal regions 16 and these are bent along the dashed lines 27 with respect to the central region 15.
  • the central region 15 is thereby bent in addition to a hollow profile with square cross-section or any other suitable cross-section, as in Fig. 2 can be seen.
  • Fig. 6 shows a not belonging to the invention V-profile.
  • the longitudinal portions 16 are folded V-shaped against each other and include as to Fig. 2 described the openings 13.
  • the profile recess 18 coincides with the folded-over longitudinal edge between the legs of the V-profile and is therefore hardly visible.
  • the openings 13 are widened by pulling the longitudinal regions 16 apart, wherein the central region 15 is fixed over the profile depression 18 in the transverse direction.
