Definitions

  • the invention relates to a compression anchor for anchor channels made of stainless steel for construction engineering, comprising a head, a shaft and a foot, which is used for the compression connection with the back of the anchor channel.
  • Bucket anchors for anchor rails of construction technology are known from DE-PS 26 31 278. These are inserted with their feet into an opening in the back of the anchor rail and connected to the back of the anchor rail by upsetting.
  • the compression anchor itself must also be made of stainless steel, since the foot partially projects into the interior of the anchor rail and not from there Concrete of a building is surrounded.
  • a compression anchor made of general structural steel is not permitted for anchor channels made of stainless steel, since the foot protruding into the interior of the anchor channel would start to rust.
  • the invention is therefore based on the object of creating a compression anchor for anchor channels made of stainless steel, which requires only low material and thus manufacturing costs and whose foot projecting into the interior of the anchor channel does not rust.
  • the invention provides that the head and the shaft are made of general structural steel and the foot of stainless steel and that the foot is firmly connected to the shaft by welding.
  • This enables the essential part of the compression anchor, namely the shaft connected to the head, to be made of inexpensive material, namely general structural steel, whereas only the base has to be made of stainless steel.
  • the shaft made of general structural steel is then firmly connected to the base made of stainless steel by welding. The resulting additional costs are relatively small in relation to the cost savings due to inexpensive Head and shaft materials.
  • the shaft is formed from two shaft parts, one of which carries the head and the other of which supports the foot, the shaft part carrying the head is made of general structural steel and the shaft part carrying the foot is made of stainless steel, and both shaft parts are fixed by welding connected with each other.
  • the shaft part connected to the head is preferably smaller in diameter than the shaft part connected to the foot, so that a bead which may occur during welding, in particular during friction welding, does not protrude beyond the larger diameter of the shaft part connected to the foot. This prevents the upsetting anchor from having a head in its area near the foot, which would determine the anchoring height of the upsetting anchor.
  • the compression anchor shown in FIGS. 1 and 2 consists of an upper shaft part 1 with an upset head 2 and a lower shaft part 3 with a foot 4 located thereon, in particular formed by upsetting.
  • the two shaft parts 1, 3 are circular in cross section.
  • the circumferential collar 5 separating the lower shaft part 3 from the foot 4 and the head 6 of the upper shaft part 1 are also circular in cross section.
  • the upper shaft part 1 together with the head 2 consists of general structural steel, in particular QSt 36, QSt 37 or QSt 52.
  • the lower shaft part 3 with its base 4 and the collar 5 consist of stainless steel, in particular the material 1.4571 or 1.4401.
  • the diameter d of the upper shaft part 1 is slightly smaller than the diameter D of the lower shaft part 3.
  • Both shaft parts 1, 3 are joined with their free end faces 6, 7 and concentric axis and firmly connected to one another by welding, in particular friction welding or stud welding. Due to the different diameters d and D, a bead formed during the welding process will not protrude beyond the larger diameter D of the lower shaft part 3, so that a bead formed here does not form an additional head which would determine the anchoring height of the compression anchor.
  • FIG. 3 shows the cross section through an anchor rail 8 with the anchor rail back 9 of the compression anchor according to FIG. 2 sprained by the foot 4 from the outside is inserted through the anchor rail back 9 and is sprained on the inside of the anchor rail back to a plate 10.
