Definitions

• the present invention relates to a construction profile, in particular a T, C, U, V, H, L, M, W, ⁇ or hat profile, as well as a method and an apparatus for manufacturing of 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 construction profile according to the invention comprises a particularly metallic elongated base body which comprises a longitudinally extending, essentially closed central region and at least two longitudinal regions extending on both sides of the middle region, in which widened openings are arranged transversely to the longitudinal extent of the main body Center region of the base body is at least one extending in the longitudinal direction of the body over its entire length extending profiled recess or increase with lateral guide surfaces.
• At least one profile recess or elevation extending in the longitudinal direction is formed with lateral guide surfaces in a middle region of an elongate material web, substantially slot-shaped openings are made in at least two longitudinal regions of the material web extending on both sides of the middle region, the profile depression or increase during a longitudinal movement of the web along a guide portion guided so that a movement of the central region is prevented transversely to the longitudinal direction and substantially in the plane of the web through the interlocking profile recess or increase and the guide portion, and the openings during the longitudinal movements of the web widened by pulling the longitudinal regions transverse to the longitudinal direction.
• the device comprises a profiling unit for producing the profile depression or elevation in the material web, a cutting unit for producing the slot-shaped openings, a widening unit for widening the openings and a guide section for longitudinal guidance of the profile recess or elevation, wherein the guide section is thus inserted into the Profile recess engages or the profile elevation overlaps that a movement of the central region of the material web is prevented transversely to the longitudinal direction and substantially in the plane of the material web.
• 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 also be advantageously produced during the longitudinal movement of the material web, in order to ensure a one-step on-line production process in this way.
• 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 construction profile 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 can be bent over after the widening of the openings relative to the central region, wherein preferably the central region is reshaped so that the longitudinal regions form the double-walled region.
• each one adjoining the respective longitudinal region outer lying region, which may be formed in particular without openings, are bent over the respective longitudinal region.
• the resulting construction profile then comprises accordingly bent outer areas, in which, in particular, no openings are formed.
• the construction profile as a T-profile rail in particular for supporting plate-shaped elements, preferably for the insertion of ceiling panels for grid ceilings, are formed.
• the middle region can form a top flange, the double-walled region a web, and the outer regions a bottom 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 can form a conductor structure or one or more comb structures, in particular intermeshing one another.
• these can be embossed into the longitudinal regions, in particular in the online process.
• the beads are not embossed directly, but the material regions of the longitudinal regions surrounding the beads are embossed, so that the non-embossed regions ultimately form protruding beads.
• the beads can be advantageously formed after the production of the openings.
• the openings form compensating sections, which substantially absorb the material stresses occurring due to the embossing process, so that a deformation caused by the embossing process takes place. gently undulating or buckling of the material web outside of the embossments 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 embossings, an undesired undulation or bulging of the material web is avoided through the openings and at the same time stiffening of the material is achieved.

• 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 each other, it is in principle also it is possible for the openings 13 in the one longitudinal area 16 to be offset relative to the openings 13 in the other longitudinal area 16, so that the openings 13 are each partially or completely covered by the material of the respectively opposite longitudinal area 16.
