Definitions

  • the invention relates to a fastening device for rods, posts, Masts or the like in the ground and a method for their production a fastening device.
  • Fastening devices for rods, posts, masts or the like for Pounding or screwing in the ground are usually by cast metal or Welding of individual prefabricated molded parts.
  • the production of cast or milled parts is relatively complex and expensive Manufacture of molded parts does not allow 100% utilization of the raw material, which also leads to an increase in the cost of production. additionally cause the joints where the individual molded parts are welded, glued or are pressed, possibly a weakening of the stability of the basic body the corresponding fastening devices.
  • a fastening device is known from DE-GM 93 13 258.1. This has one that can be screwed into and out of the soil Threaded section and a holding section for receiving the Rod, post, mast or the like on, being between the threaded portion and the holding section a conical, when screwing the fastening device effective displacement body for the soil is arranged.
  • the threaded section is a cast part and carries a helical one Thread.

  • the threaded section of the anchoring section which is designed as a casting with a solid core, requires a large amount of material.
  • the one that remains the same over the entire anchoring section relatively obtuse cone angle on the one hand more difficult due to occurring Radial forces screwing the fastening device into the ground and does not allow secure fastening of the fastening device due to the cone shape in the ground, because radially occurring due to the obtuse cone angle Forces, such as vibrations, cause to loosen the anchoring section from the ground.
  • the fastening device according to DE-PS 40 02 830 consists of plastic material, which requires production by lamination, thermoforming, injection molding, etc. Due to the necessary preliminary work, these processes are relatively expensive and therefore expensive. An anchoring section produced in this way does not have any stability-reducing joints, but in order to achieve the necessary stability, it must be made of solid material.
  • EP 0 590 367 A1 discloses a knock-in floor anchor with longitudinal grooves, which has a channel as the receiving cavity.
  • the floor anchor according to EP 0 590 367 A1 can be manufactured by injection molding from plastic, but it can also be made in several pieces from steel.

It can also be two, three or more sections of different conicity. At least a portion of the displacer can carry a screw or screw-shaped thread for screwing in and out of the soil, but this is not mandatory. If the fastening device is intended to be driven into the ground, the thread is omitted.

  • the anchoring section is essentially formed over its entire length as a conical, essentially acute-angled displacement body for the soil, the fastening device is clamped into the soil when it is driven into or screwed into the earth, since the soil and stones over the entire cone length are essentially pointed Displacement body angles are displaced.
  • the forces displacing the soil and any stones are greater than in the case of fastening devices which essentially displace the soil only in a relatively obtuse-angled displacement body region between a threaded section and the holding section. This makes driving in or screwing in easier.
  • the advantage over a consistently constant cone angle over the entire anchoring section is that at the beginning of the screwing in, a smaller cone angle facilitates the setting and aligning of the fastening device in the ground and keeps the force required when driving in or screwing in low.
  • the anchoring section consists of a blank is formed in one piece and thus no connection points in this area different composing parts occur, results in Compared to the prior art, improved stability of the anchoring section and the fastening device.
  • anchoring section and the holding section are integrally formed to the stability of the entire device to increase further.

  • the thread is part of the basic shape of the base body of the anchoring section attached, in particular welded.
  • the pull-in forces of the corresponding thread are of size the effective area on the thread. Because the entire anchoring section is conical, i.e. because the diameter of the thread-bearing areas of the anchoring section increases, too the thread diameter and thus the effective area on the thread greater.
