Definitions

  • the invention relates to a sleeve anchor for concrete parts an internally threaded stop sleeve and one Anchor shaft with molded anchor foot, the anchor shaft with a shaft end in a connecting section of the Raised stop sleeve, which presses radially with the shaft end is.
  • Such sleeve anchors serve as transport anchors Striking concrete parts, especially precast concrete parts, on hoists and transport equipment.
  • the sleeve anchor are embedded in the manufacture of the concrete parts in such a way that the stop sleeve is accessible from the outside.
  • Threaded studs are screwed to the concrete part to lift and transport.
  • the object of the invention is therefore a sleeve anchor for Concrete parts of the type mentioned above to design that a corrosion protection and in particular also a tight seal against the internal thread of the Stop sleeve is reached.
  • the plastic cap covers the front of the anchor shaft Completely; your cap frame is when pressing the Stop sleeve on the shaft end in the threads deformed into that a completely tight seal he follows.
  • the frictional connection between the Stop sleeve and the anchor shaft is deformed by the Cap frame not affected.
  • the cap frame preferably extends over only one Part of the length of the pressed with the shaft end Connecting portion. Doing so with little Material expenditure for the plastic cap a more dense Degree reached; there is no need to Pressing process a larger amount of To displace plastic material lengthways.
  • Sleeve anchors are the subject of further subclaims.
  • the invention also relates to a method for Production of such a sleeve anchor.
  • a Stop sleeve with an internal thread Connection section over a shaft end of an anchor shaft is inserted and pressed radially with it, that is Method according to the invention characterized in that before pressing a closed plastic cap onto the Pushed on the shaft end and their cap frame between the Internal thread of the connecting section and the shaft end is pressed radially.
  • Pushing the plastic cap onto the anchor shaft is made in a simple, little in manufacturing elaborate operation. It is not an application of liquid corrosion protection material required.
  • the sleeve anchor shown in FIGS. 1 and 2 for Concrete parts have an essentially smooth cylindrical Anchor shaft 1 made of non-corrosion-resistant structural steel, at one end a plate-shaped anchor foot 2 is molded. The other shaft end 3 is with one Stop sleeve 4 made of corrosion-resistant steel.
  • the stop sleeve 4 has a continuous internal thread 5 on that in its protruding beyond the shaft end 3 Section for screwing in a threaded pin is used.
  • a connecting section 6 into which the shaft end 3 protrudes the stop sleeve 4 is radial with the Shank end 3 pressed.
  • the shaft end 3 carries one closed plastic cap 7, the end face 8 of the Shaft end 3 covered and with its cylindrical Frame 9 over the outer portion of the shaft end 3 extends and on this preferably with a close fit is applied.
  • the cap frame 9 only protrudes part of the length of the pressed with the shaft end 3 Connecting section 6 of the stop sleeve 4th
  • the shaft end 3 carrying the plastic cap 7 protrudes the connection section 6 pressed therewith into the Inner bore of the stop sleeve 4. This remains Section of the cap frame 9 in the unpressed area of the Stop sleeve.
  • Stop sleeve 4 becomes the cap frame 9 of the plastic cap 7 pressed into the threads of the internal thread 5 and fills the cavities remaining during the pressing process Thread base completely and sealingly.
  • the shaft end 3 is also in its end section carrying the plastic cap 7 in the initial state smooth cylindrical and is by the radially pressed internal thread 5 of Connection section 6 permanently deformed.
  • Fig. 3 shows the parts of the sleeve anchor before pressing.
  • the Cup-shaped closed plastic cap 7 put on.
  • the shaft end 3 is then shown in FIG Way in the 5 provided with internal thread Anchor sleeve 4 introduced.
  • the connecting portion 6 is radial pressed against the shaft end 3.
  • the internal thread 5 causes permanent deformation of the Initial state of the smooth cylindrical surface of the Anchor shaft 1.
