Definitions

  • the invention relates to a conical mast made of metal with a closable opening.
  • Conical masts made of metal, in particular made of steel, are used as lighting masts, antenna masts or poles.
  • conically rounded blanks are produced, the longitudinal seam of which is closed by welding.
  • the document NL 7114828 discloses a light pole whose cross-section is constant in the lower region and which tapers in the upper region.
  • the light pole has an opening that allows access to the interior of the mast.
  • the opening is reinforced by an inserted inner tube.
  • a mast which has a constant diameter and an opening in its lower region, the upper region is conical.
  • the mast has an inside reinforcement, which is provided with ribs.
  • Conical masts that are placed on the roadside must meet certain crash safety requirements. It has been found by crash tests that thin-walled masts provide increased passive safety for vehicle occupants as they "roll up" in a collision with a motor vehicle, thereby keeping the acceleration values applied to the vehicle occupants below an allowable limit. On the other hand, conical masts must also be static Meet requirements, so that a certain minimum wall thickness must not be fallen below.
  • Conical masts have at the bottom of a longitudinal opening which is closed with a lid or a door. This opening allows access to the interior of the conical mast in order to connect mast lighting to an electrical network after the conical mast has been set up.
  • electrical or electronic components may be mounted inside the mast, such as a fuse.
  • the invention is therefore based on the object to provide a conical mast, which has a favorable crash behavior in collisions with motor vehicles and at the same time is so stable that can be mounted in its interior electrical or electronic components.
  • the reinforcement provided according to the invention naturally leads to an increased wall thickness in this area, whereby a better protection against vandalism and damage is achieved.
  • the mast above the gain of the desired reduced wall thickness whereby a favorable crash behavior is achieved.
  • the reduced wall thickness leads to a lower material consumption and correspondingly lower production costs.
  • the material used can be better utilized.
  • the reinforcement is sleeve-shaped and pressed into or onto the conical mast.
  • an integral component is created, which has an increased wall thickness in the area of the reinforcement.
  • the prefabricated conical mast and adapted to this conical reinforcement can simply be inserted into one another under the action of force, alternatively, the two components can also be connected to one another by friction welding.
  • the conical mast can be made of galvanized steel, which provides good protection against corrosion.
  • the reinforcement provided in the conical mast according to the invention may preferably be made of stainless steel, so that the lower part of the conical mast is protected against corrosion.
  • a variant of the conical mast according to the invention provides that the upper edge of the reinforcement is inclined relative to a plane perpendicular to the mast longitudinal axis.
  • the plane spanned by the reinforcement is tilted after erection of the mast, whereby the drainage of rainwater is facilitated. Therefore, the unwanted ingress of rainwater into the gap between the conical mast and the reinforcement is prevented.
  • the conical mast in the inside reinforcement opposing edges of the reinforcement are each bent to a C-profile, the C-profiles serve as a carrier for electrical or electronic installations, which are accessible through the closable opening.
  • the reinforcement of the conical mast according to the invention has an opening which is wider than the opening in the mast. In this way, a stable support for the lid or the door, with which the opening is closed.
  • Fig. 1 shows a mast 9, which has an inside reinforcement 10 in the region of the opening 5.
  • the inside reinforcement 10 is sleeve-shaped and pressed into the hollow mast 9, so that it has an increased wall thickness in the region of the opening 5. This wall thickness stabilizes the region of the opening 5 or a cover or door attached there, so that the mast 9 is not substantially weakened in the region of the opening 5.
  • the lower end 11 of the mast 9 is inserted into the ground, below the surface there is a further opening 12 through which electrical lines inside the mast 9 can be fed.
  • Fig. 2 shows the mast of Fig. 1 cut along the line II - II. As in Fig. 2 is shown, the galvanized steel existing mast 9 and the inside reinforcement 10 are firmly connected. As in the first embodiment, the opening of the mast 9 is wider than the opening of the inside reinforcement 10, so that vertical support portions 13 for a lid or a door are provided on both sides of the opening.
  • the inside reinforcement 10 is bent at the side opposite the opening in each case to a C-profile 14.
  • the free ends of the C-profile 14 serve as a carrier for a device web 15, on the z. B. a fuse can be attached. The attachment is done by pushing on the device web 15.
  • Fig. 3 shows the area of the impact of the inside reinforcement 10 in an enlarged view. It can be seen that the device web 15 can be pushed over the free end portions of the C-profile 14 and remains clamped in this position without further fasteners. In Fig. 3 It can also be seen that the mast 9 made of galvanized steel is welded by means of a weld 16 which extends over the entire wall thickness.
  • Fig. 4 shows an enlarged view of the mast of Fig. 1 in the area of the opening. As in Fig. 4 can be seen, serving as a door reinforcement inside reinforcement 10 is bent over its entire length to the C-profile 14, so that the vertical position of the device web 15 can be adjusted.
