Definitions

  • the invention relates to a support screw for supporting a facade panel, in particular precast concrete parts, opposite a supporting wall with a threaded rod that can be supported in the supporting wall and a nut at the supporting end.
  • Such a support screw is known for example from brochure 0950/0954 from the FRIMEDA metal and wire goods factory from 1978.
  • This known support screw consists of a threaded rod which is screwed into a threaded sleeve acting as a locking part in the supporting wall and at the end of which a screw nut is screwed, which is welded to a flat metal plate, the outside of which forms the support surface on which the curtain wall panel is attached supports.
  • a threaded rod which is screwed into a threaded sleeve acting as a locking part in the supporting wall and at the end of which a screw nut is screwed, which is welded to a flat metal plate, the outside of which forms the support surface on which the curtain wall panel is attached supports.
  • three different parts are required to produce this known support screw, which have to be fixed to one another by a relatively complex welding process.
  • Support screws are also known in which a round head is warmly swaged in order to enlarge the head area compared to DIN screws, which is required to hold the concrete pressure.
  • support screws of this type are very expensive to manufacture and to store due to small quantities with different lengths and diameters.
  • the object of the invention is to simplify a generic support screw both in terms of material and in terms of its manufacture and thus to make it cheaper.
  • This pressing can be carried out relatively easily by the so-called cold extrusion.
  • the deformation of the nut takes place from the part pointing towards the supporting wall, where it is less required, towards the part on the support side, where it leads to an increase in the cross-section of the pressed-on nut and thus at the same time forms a sufficient support surface without the need for a separate support plate.
  • the anchoring-side end of the nut is pressed conically onto the threaded rod and that the end of the threaded rod tapers in the area of the pressed-on nut.
  • both a certain saddling of the pressed-on nut on the threaded rod is achieved, and also a broad introduction of the supporting forces from the widened end face of the nut on the supporting side via the tapered cone into the threaded rod.
  • the tensile and compressive stresses which can be absorbed by a conventional nut can be positively influenced by this change in shape of the contact surfaces between the nut and the threaded rod caused by the pressing-on process.
  • the nut is screwed onto the threaded rod so far that, after the pressing-on process, the end face of the threaded rod on the support side is flush with the end face of the pressed-on nut on the support side, so that they form a flat support surface.
  • the support-side end of the pressed-on nut is shaped in such a way that it continues to form a hexagon flange which can be rotated with commercially available tools in order to fix the support cap in its position in the threaded sleeve anchored in the supporting wall.
  • the other end of the threaded rod 12, together with the pressed-on nut 11, serves to support the facade plate 40 with respect to the supporting wall 30.
  • the nut 11 pressed on according to the invention has an increase in cross-section and material accumulation on its support-side end face 11a, which corresponds to a corresponding material reduction at the other end, at the foot of the cone 11c.
  • the cross section of the threaded rod 12 tapers in the direction of its end face 12a on the support side, so that an optimal introduction of the compressive forces from the facade plate 40 into the threaded rod 12 results, since the pressed-on nut 11 transmits the compressive forces practically in the manner of a truss structure.
  • another support part can also be used in an equivalent manner instead of a nut.
