  • Metal supports of the generic type for ceiling substructures are known in the art. That's how it describes GB 2 456 328 A a corresponding metal carrier, which is designed in the form of a T-profile is.
  • the metal support according to the British application is also formed from a double sheet and has at the web-side end of a hollow profile.
  • the linear hollow profiles are formed by the double plate and are present substantially over the entire length of the metal carrier.
  • GB 2 274 080 A shows a metal carrier according to the preamble of claim 1.
  • the metal carrier in the web area with reinforcing ribs ("stitching"), wherein the reinforcing ribs have been pressed both from the outside of the first sheet in the direction of the second sheet as well as from the outside of the second sheet in the direction of the first sheet ,
  • the core of the invention is thus a "double-sided stitching".
  • the metal carrier is designed so that the pressed-in reinforcing ribs ("stitching") parallel to the flange in line shape, preferably over the entire length of the metal carrier, are pressed.
  • the invention in this case comprises embodiments in which the press-ins are alternately, i. from one side and the other side, as well as embodiments in which there are several pressings successively from one side and then again several pressings in succession from the other side.
  • the reinforcing ribs alternate in a line shape in each case, i. an injection from the outside of the first sheet in the direction of the second sheet, and then the next press-in from the other side of the sheet are introduced.
  • the distances between the pressings can also be variable.
  • a further preferred embodiment then provides that the reinforcing ribs are pressed into two or three lines arranged parallel to the flange. Within the respective parallel lines with the "stitching", the number of impressions that are pressed in from the first side in the direction of the second side and vice versa may vary.
  • the invention also includes embodiments in such a way that the reinforcing ribs are pressed in line form starting from the outside of one of the sheets and are pressed in parallel in a second line arranged therefrom, starting from the outside of the other sheet.
  • the reinforcing ribs of the two lines are arranged on a gap are, that is, a press-fitting, which is pressed from one side in the direction of the other sheet, is offset from the other press-in, which has been introduced from the other side, arranged.
  • the pressed-in reinforcing ribs are arranged parallel to the flange in line form in the vicinity of the flange.
  • a further preferred embodiment then provides that reinforcing ribs are provided in a second line parallel thereto, wherein these reinforcing ribs are then provided at the web-side end.
  • the impressions are preferably provided in the last third of the web area.
  • the two-sided "stitching" can not be distributed in line form, but distributed over the surfaces of the web area. Also for this embodiment, the number of press-in is variable.
  • the reinforcing ribs are introduced into the web by a two-step process.
  • a tab is cut free from the material.
  • the second process step is then carried out by a stamp pressing, so that a flow of the material of the tab takes place. By this pressing is then ensured that the tab can not be pushed back into the recess.
  • the invention also includes embodiments in which the compression is produced by a one-step process, i. In one operation, the tab is cut free and pressed.
  • the compression is made by a single punch or by a double punch in a rectangular shape.
  • the long sides of the rectangle are in the range of 2 to 8 mm and the short sides are 0.1 to 1.5 mm long.
  • This linear reinforcing profile can be formed as a hollow profile by the two double sheets and is preferably arranged parallel to the line-shaped "stitching". In this case, a preferred embodiment provides that the linear reinforcing profile is arranged between two line-shaped pressings.
  • the metal carriers according to the invention may additionally, as is known per se from the prior art, still have openings which are provided for latching the metal carriers to one another.
  • the metal carriers according to the invention may then also have connectors, which are arranged on the front side at the respective ends of the metal carrier, which are provided to lock the metal carrier with each other through the opening.
  • the metal carriers according to the invention may be metal carriers of a length of 50 to 400 cm, depending on the application. Such metal beams can be used for ceiling substructures, which then act either as a main or as a cross member.
  • the selection of the length of the metal support depends of course on the application, i. depending on whether it is a main or a cross member.
  • the T-profile of the metal carrier preferably has a web height in the web region between 1 and 8 cm.
  • the material of the metallic supports is preferably a steel sheet of a cold-rolled strip.
  • the steel grades include integrated carbon steels with carbon mass fractions up to 1%, a preferred steel sheet is DX 51 Z 100.
  • the metal support according to the invention is as described above particularly suitable for metallic ceiling substructures as the main and / or cross member, wherein the flange points in the direction of the interior of the room.
  • FIG. 1 is shown in cross section a metal carrier 1 in the form of an inverse T-profile.
  • the metal carrier after FIG. 1 is formed of a double sheet 3, 4 and has at its web-end a hollow profile 5, which has been formed by the two double sheets.
  • FIG. 1 is now seen in cross-section that the pressings (stitching) 6, 6 'have been introduced from both sides in the web portion 2 of the metal carrier 1.
  • a first line shape has been formed at the flange end, in which case the press-in 6 from one side, ie from the outside of the sheet 3, have been introduced, whereas the press-in 6 'have been pressed from the outside of the sheet 4.
  • the embodiment according to FIG. 1 thus has a double-sided stitching, each with two lines are provided with alternating pressings.
  • FIG. 2 now corresponds to the one after FIG. 1
  • the indentations 6 have been introduced at the web-side end only from one side, ie only from the outside of the sheet 3.
  • the indentations 6, 6 ' which are arranged at the flange end, always from the outer side. 3 (Press 6) and from the outside 4 (press 6 ') have been made.
  • FIG. 3 Now, a metal carrier according to the invention is shown, which by the example FIG. 2 emanating and differs in that between the flange-side line-shaped press-in and the web-side linear press-in nor a hollow section 8, which is formed by the two sheets 3, 4, is arranged. This achieves a further improvement in rigidity and distortion.
  • FIG. 4 is now a perspective view of a metal support 1, which illustrates that the press-in 6, 6 'in line form and thereby alternately formed at the flange-side end of the web portion 2.
  • the press-6 has been made from the non-visible page in the page shown.
  • the invention of course includes all embodiments in which, for example, then two or three pressings have been made in the same direction and then two or three pressings have been carried out from the other side.
  • the invention also includes embodiments in which, for example, in one line only 20% or 30% of the impressions have been made in one direction and correspondingly 80% or 70% of the impressions from the other direction.
  • FIG. 5 is now in turn a perspective view of a metal support 1 shown, in which the press-in 6, 6 'are executed in two lines, on the one hand in a first line, which is formed on the flange side, and in a second line, which is provided at the web-side end ,
  • the perspective view of the metal carrier after FIG. 5 corresponds to the representation of the metal carrier in cross section FIG. 1 , From the illustration to FIG. 5 It is also clear that the distances of the respective impressions can be chosen arbitrarily. In the example after the FIG. 5 are provided between the press-in, which are provided at the web-side end below the hollow section 5, much greater distances than for the press-in, the flange-side end are arranged.
