Definitions

  • the invention relates to a material stabilized against deflection, preferably sheet metal.
  • a well-known example of a stabilization of thin sheet metal or plastic is the corrugation, such as for corrugated sheet or corrugated plastic, which is preferably used as corrugated sheets for roof coverings.
  • a peculiarity of these corrugated, thin materials is that sufficient stabilization is achieved only in the longitudinal direction of the waves, but not in their transverse direction.
  • complex substructures such as roofs, often have to be accepted in order to make the roof area safely accessible, for example.
  • the invention has for its object to make flat material with simple means and material-saving rigid.
  • the stabilization according to the invention can be used on practically all flat materials, preferably sheet metal or plastic. According to claim 1, therefore, plates with great longitudinal but also transverse stability can be produced.
  • the claims 2 and 3 identify strips in which - depending on the expected load - the continuous beads in the longitudinal direction of the strips, but also in the transverse direction can be arranged.
  • a preferred application of the invention is characterized in claims 13 to 15. Recently, more and more pipe or cable hangers have been required, which can be produced in a material-saving and inexpensive manner. With conventional cable or pipe supports, the manufacturing costs are burdened with around 70% to 80% material. Due to the inventive design of the cable and pipe supports, preferably according to claims 13 to 15, for example, a sheet reduction from 1.5 mm to 1.2 mm thick can be responsible for the stability without damage. This results in savings in the operating weight and consequently in the material costs of approx. 20%.
  • a material 1 for example sheet metal or plastic, which is provided with continuous beads 6 in a first direction 5.
  • These continuous beads 6 have two roof sides 7 and 8 and a ridge 9. Without changing anything at the core of the invention, curved or differently shaped continuous beads 6 can also be used.
  • the continuous beads 6 are penetrated by short transverse beads 12 which are arranged either along a second direction 11 or transversely to the first direction 5. Depending on the application, any angle 10 can be provided between the first direction 5 and the second direction 11.
  • FIG. 1 shows, for example, short transverse beads which are molded into the continuous beads 6 from the ridge 9.
  • arcuate penetration edges 15 or straight penetration edges 16 are formed.
  • the short transverse beads are formed towards the ridge 9, the material 17 being next to the continuous bead 6 for penetration through the short transverse bead 12 is used.
  • FIGS. 4 to 8 The individual forms of penetration are shown again in FIGS. 4 to 8. 4, the short transverse bead 12 is formed towards the ridge 9, whereby an arcuate penetration edge 15 is created. A roof side 8 is shown from the continuous bead 6.
  • FIG. 7 shows a material 1 with continuous beads 6 and short transverse beads 12 arranged in them, which are arranged offset to one another.
  • the continuous beads 6 again run along first directions 5, but these are arranged in the same direction as the transverse direction 4 of the strip 2.
  • the transverse beads 12 run along the second direction 11, which runs in the same direction as the longitudinal direction 3 of the strip 2.
  • the transverse beads 12 also extend into the material 17 in addition to the continuous beads 6.
  • FIG. 9 shows an embodiment of the invention in which it is used to form a cover 18. whose surface 19 is provided with continuous beads 6 and short transverse beads 12. The surface 19 is surrounded by an edge region 20 which has side edges 20a which are joined together. If the cover 18 is made of sheet metal, the side edges 21 are preferably welded together. If, however, the cover 18 is made of plastic, the side edges 21 are firmly connected to one another in another way.
  • Previous pipe or cable carriers 21 consist of relatively thick sheet metal.
  • the sheet thickness can be reduced from 1.5 mm to 1.2 mm. This reduces the manufacturing costs by 20%.
  • the pipe or cable supports 22 provided with the invention have a base 23 which, according to the invention, is provided with continuous beads running in the longitudinal direction and short transverse beads arranged in a second direction.
  • the floor 23 merges into longitudinal walls 24 which point obliquely outwards.
  • the free edges 25 of the longitudinal walls 24 are provided with flanges 26.
  • transverse beads 12 instead of transverse beads 12, other corresponding deformations can be used which penetrate the continuous beads and ensure the transverse stability of the material.
