Definitions

  • the invention relates to an anchor and / or connecting device for concrete parts or the like, which comprises a connection part protruding from the concrete part and an anchoring part embedded in the concrete part.
  • the anchoring part has the task of improving the hold of the device in the concrete part, while the connecting part is accessible on the outside of the concrete part and can be connected to a lifting tool or a connector.
  • the connection with a lifting tool is selected when transporting the concrete part, while the connector is used to create a connection between two concrete parts on site.
  • the device consisting of the connecting part and the anchoring part remains embedded in the concrete part. The device is therefore a mass product which is to be manufactured very cheaply and yet has to have a sufficient load-bearing capacity.
  • connection part is exposed at least in the area of its star side on the concrete part. If the device is used to connect concrete parts, this area is exposed to atmospheric influences.
  • the cheap concrete and structural steels fail for such a device and it is necessary to switch to stainless steels or refined surfaces. These stainless steels or refined parts are, however, considerably more expensive and therefore involve a very considerable increase in the cost of such a device. This configuration is unsatisfactory, especially when most of the device is embedded in the concrete part.
  • the connecting part and the anchoring part are formed as separate parts which are firmly and permanently connected to one another by means of friction welding, the connecting part made of stainless steel or of a metal with a refined surface and the anchoring part made of construction or Reinforcing steel exists.
  • Friction welding is a work process that is easy to control and can be carried out much faster than the usual welds.
  • the subdivision of the device into a connecting part and an anchoring part allows an optimal material adaptation.
  • the connecting part consists of stainless steel or with a refined surface and the anchoring part consists of concrete or structural steel with an unprocessed surface.
  • This design is sufficient, since only the connector is exposed to atmospheric influences. As a result, considerable cost savings can be achieved by reducing the proportion of stainless steel or of refined material.
  • the anchoring part of the device embedded in the concrete part can be made of cheap concrete or structural steel.
  • anchor and / or connecting devices the parts of which are made of different materials, can also be produced in this way.
  • connection part is designed as a bolt with a threaded part and that the bolt-free end of the bolt is connected by friction welding to an anchor plate as an anchoring part.
  • the bolt with the threaded part can be produced cheaply in known operations, the anchor plate being able to have a rectangular, square or round cross section.
  • the friction welding is carried out simply by a part, e.g. the bolt on the other part, e.g. the anchor plate, is under pressure and is set into rapid rotary movements. After sufficient heating, the rotary movement is ended and the parts are pressed against one another while increasing the pressure.
  • the cost of materials for expensive stainless steel or refined metal can be reduced even more with such an anchor and / or connecting device in that the threaded part itself is connected to the bolt as a separate part by means of friction welding.
  • the threaded part remains partially free in this device and is used to connect a lifting tool or a connector with a threaded hole.
  • only the threaded part needs to be made of stainless steel, or must be provided with a finished surface alone. All other parts can be made of cheap structural or reinforcing steel.
  • the device can also be designed such that the connecting part is designed as a bolt with an upset, enlarged cross-section joint part and that the other end of the bolt is connected by friction welding to an anchor plate as an anchoring part.
  • the joint part is exposed in the concrete part and is used to link a joint counterpart, preferably a lifting tool.
  • the device according to the invention is designed so that the connecting part is designed as a sleeve which is provided with an internal thread on at least one side and is closed at the other end by means of friction welding with an anchor plate as an anchoring part.
  • the material expenditure of stainless steel can be reduced to a minimum by connecting the sleeve without internal thread by means of friction welding to a separate threaded sleeve.
  • connection part is designed as a pot-like sleeve with a blind bore and internal thread, and that at least one bolt is attached to the bottom of this pot-like sleeve by means of friction welding, the free end of which being compressed is enlarged in cross section.
  • the pot-like sleeve can then be produced from a section of a round material in normal operations. In this case, a cheap bolt with an upset head is used as the anchoring part, which is quickly connected to the sleeve without affecting the strength.
  • the anchor and / or connecting device can also be designed for even greater load capacities.
  • the connecting part is designed as a fastening plate, at the rear of which at least one bolt is attached as an anchoring part by means of friction welding and that the free end of this bolt is enlarged by upsetting or is connected to an anchor plate by means of friction welding. Beams, struts or the like can then be welded to the fastening plate, which is preferably inserted flush with the top side into the concrete part.
  • This welding process on site can be dispensed with if the design is such that the connecting part is designed as a mounting plate with bores and that a sleeve with an internal thread or a pot-like sleeve with a blind bore and an internal thread is attached to the rear of each bore by means of friction welding is.
  • the carriers, struts or the like can then be screwed directly to the anchor and / or connecting device.
  • the sleeve can be closed at the free end by means of friction welding with an anchor plate.
  • at least one bolt with an upset, enlarged end with a cross section is attached to the bottom of the sleeve as an anchoring part by means of friction welding.
  • several bolts can also be attached to a sleeve with a large cross-section in this way.
  • a common anchor plate can then be provided for all bolts.
  • the hold of the anchoring part in the concrete part can be significantly improved in such a composite anchor and / or connecting device in that the bolt or sleeve is provided with an external thread.
  • This additional external thread can be applied without any significant manufacturing effort in the manufacture of the anchoring parts.
  • a section of a threaded rod can also be used as the anchoring part.
  • An anchor device is advantageous for claw-like lifting tools, which is characterized in that the connecting part is designed as a ball.
  • This ball as a connecting part provides an excellent articulated connection between the anchor device and the lifting tool.
  • the upset end of the anchoring part can also be designed such that the free end of the bolt or the sleeve are provided with mushroom-like upsets. These mushroom-like upsets provide a large additional abutment surface for the anchoring part.
  • the connecting part commercially available parts can also be used if, according to a further embodiment, it is provided that the connecting part is designed as a nut with a thread length which corresponds to at least 1.5 times the thread diameter.
  • the anchoring parts can be produced from commercially available parts in a simple manner if the design of the anchor and / or connecting device is selected such that a section of a threaded rod is used as an anchoring part, which is connected to the nut by means of friction welding.
  • the ends of two anchoring parts are firmly and permanently connected to one another by means of friction welding to form a double anchor and that the remaining ends of the anchoring parts are each connected to a connecting part.
  • the connection point of the two anchoring parts of the double anchor then forms a kind of water barrier.
  • a double anchor for connecting a lifting tool with a threaded part is characterized in that two sections of a threaded rod are connected to one another as anchoring parts of a double anchor and that nuts with an enlarged thread length are screwed onto the free ends of the double anchor as connecting parts.
