Definitions

  • the invention relates to a sheet metal profile with a U-shape for building walls, which forms a web sheet metal strip and two leg sheet metal strips and forms a beading with longitudinal, transverse, intersecting beads.
  • a known (DE-PS 34 42 355) sheet metal profile of this type has a corrugation which comprises a group of precisely longitudinally oriented, linear longitudinal beads and a group of transverse beads which can be arranged either at right angles or obliquely to the longitudinal direction.
  • the two groups of beads are necessary in view of the desired rigidity.
  • a roller When creating the beading, a roller is used, which has a printed pattern on the peripheral jacket that presses the beads into the sheet.
  • Continuous beads are the print pattern continuously engaged in the sheet, so that the production of the longitudinal beads is associated with relatively little noise.
  • the printing pattern for the transverse beads again engages the sheet metal, which occurs suddenly and is associated with a relatively large amount of noise.
  • the sheet metal profile according to the invention solving this problem, is characterized in that the beading is formed by two serpentine, meandering beads which are in the form of a back and forth and which are offset from one another.
  • the beading can be produced with considerably reduced noise.
  • the sheet with the meandering beads has the required rigidity in both directions.
  • the two meandering beads prevent the sheet profile from being soft and ensure the required rigidity.
  • an endless printing pattern is provided on the circumferential surface of the roller, which is in constant engagement, which is why less noise is generated and the beading machine is stressed less.
  • the meandering beads are usually of the same design and dimensions.
  • the meandering beads are e.g. sinusoidal and rounded, resulting in a beading pattern composed of "8" th.
  • the meander beads run back and forth with straight, obliquely arranged, angled bead sections and form the sequence of diamonds.
  • This design of the meandering beads can be done with a pair of rollers that is easier to manufacture, i.e. with a simpler print pattern on the circumferential surface of the pair of rollers.
  • the diamond beading tool is cheaper.
  • the meandering beads can extend both on the web sheet strips and over the corner area on the two leg sheet strips. However, it is particularly expedient and advantageous if the meandering beads each extend in a corner area to only cut out on one sheet metal strip. The corner area between one of the leg sheet metal strips and the web sheet metal strip is free from meandering. Beading introduced in the corner area would go back when the leg metal strips were raised forms what is associated with a loss in strength of the material.
  • both the two leg metal strips and the web metal strips with meandering beads.
  • the meandering beads are provided either only on the web sheet metal strip or only on the leg sheet metal strips. This simplifies production. This is because the web sheet metal strip is usually beaded after the leg sheet metal strips have been bent open, and the leg sheet metal strips are beaded before being bent open, so that two beading processes and two tool types are necessary for the beading of both sheet metal strip types.
  • the diamonds at the longitudinal edge of the sheet section an angle of 30 - 150 o form. This is an arrangement between the exactly longitudinal arrangement and the right-angled arrangement of the bead sections, which provides sufficient rigidity for most applications.
  • the sheet profile has, for example, a pure U-shape in cross section or is provided with bends at the free ends of the leg sheet strips, for example a C profile.
  • the meandering beads can be created both on the long belt and on the short board. The meandering beads result in a reduced number of crossings when looking at the unit length of the sheet metal profile.
  • a straight, additional longitudinal bead for example in the web sheet metal strip, can be provided.
  • Under construction walls are not here understood only vertical walls, but also horizontal ceilings.
  • the sheet metal profiles are stands or supports in the building walls and serve to attach wall panels.
  • a pair of rollers with a correspondingly new printing pattern is used, which is endless for a meandering bead and consists of two parts, each of which extends over the length and over the circumference of the rollers, is offset from one another by 180 ° and both ends the rollers merge.
  • the sheet profile in FIG. 1 has a web-metal strip 1, respectively, a 90 o angled leg-metal strip adjoins the two longitudinal sides of a deck area 2 3, which on the the web-metal strip opposite end terminates freely.
  • the leg strip of sheet metal at this free end in FIG. 2 provided with a 90 o angled bend. 4 1 is only in the web sheet metal strip 1 and the sheet profile according to FIG. 2 is provided with a beading only in the leg sheet metal strip 3.
  • the beading consists of two meandering beads 5, 6, which are formed by straight bead sections 7, which form an angle 8 to each other.
  • a straight longitudinally extending, centrally arranged bead 11 is indicated by dashed lines, which brings a further stiffening of the sheet metal profile.
