Definitions

  • the invention relates to a standpipe for signs, in particular traffic signs, from a square tube section.
  • the standpipe from a round or square pipe section is usually anchored in the ground or attached to parts that are fixed to the ground, it represents a constant source of danger in traffic, especially road traffic. Especially when starting off, large material and / or or personal injury.
  • This object is achieved according to the invention in that two mutually opposite side walls of the square tube section are drawn in continuously in a V-shape in the longitudinal direction and in that the wall thickness of the drawn-in side walls in the longitudinal direction is reduced in the longitudinal direction in a groove-like manner at the drawing-in edges and at the transitions of these drawn-in side walls into the adjacent flat side walls is.
  • the sign is attached to this standpipe parallel to one of the flat side walls, so that the direction of impact coincides with the retracted side walls when moving off.
  • the standpipe When the standpipe is started up, the drawn-in side walls are folded inwards in the manner predetermined by the weakened wall areas, and that at any point in the longitudinal direction of the standpipe. The location of the folding point depends on the point at which the impact forces are greatest.
  • the standpipe will kink at this fold, but it won't break off. With this standpipe, it doesn't matter how deep it is in the socket of a foot.
  • the folding and folding process is further favored in one embodiment in that the partial side walls of the retracted side walls. have a smaller wall thickness than the adjacent flat side walls.
  • a further embodiment provides that the wall thicknesses of the retracted side walls are weakened on the inside of the retracted side walls.
  • the folding process of the standpipe, combined with a kink, is also favored according to further embodiments in that the dimension of the square tube section in the direction of the retracted side walls is greater than the dimension of the adjacent flat side walls and that the retracting edges are retracted by more than the wall thickness of the retracted side walls are (rectangular pipe section).
  • the production of the standpipe is carried out in the simplest way by cutting a correspondingly shaped profile strand, which already has the drawn-in side walls with the weakened wall areas in the correct position in one work step.
  • the manufacture can also take place in such a way that the square tube section is formed from a rolled and electrically welded steel sheet.
  • the standpipe essentially has the cross-section of a square tube.
  • the square tube section 10 used, however, only the opposite side walls 11 and 12 are flat.
  • the standpipe is aligned so that these side walls 11 and 12 run parallel to the shield attached to the standpipe.
  • the shield is then approached essentially in such a way that the V-shaped retracted side walls 13 and 14 are stressed.
  • the shield can be attached to one or more such standpipes.
  • the V-shaped retracted side walls 13 and 14 are divided into the partial side walls 13.1 and 13.2 or 14.1 and 14.2 of the same size.
  • The. central retraction edges 15 and 16 lie in a retraction depth 23 and 24, which is greater than the wall thickness of the retracted side walls 13 and 14.
  • the retracted side walls 13 and 14 have the purpose that they can fold when the standpipe is started. In order that this folding process is promoted, the drawn-in side walls 13 and 14 in the area of the drawing-in edges 15 and 16 are continuously weakened in a groove-like manner, as the wall areas 17 and 18 show.
  • the cross section of the square tube section 10, as shown in FIG. 1, is obtained in one operation when the extruded or rolled profile strand from which the square tube section 10 is cut to length. already has this cross-section. This can be achieved solely through the tool used in the manufacture of the profile strand. An aluminum extrusion from which the appropriate lengths are separated is preferred. However, a rolled and electrically welded steel sheet can also be used to produce the square tube section.
