Definitions

  • the invention relates to a connector for Joining the ends of threaded steels.
  • reinforcing bars are often used in reinforced concrete construction used for example in Precast reinforced concrete slabs are used as they are for example in the manufacture of so-called solid Roadways for high-speed rail traffic are common.
  • the Reinforcing bars inserted as reinforcement in the concrete and serve to absorb the tensile forces and on the Transfer concrete (the compressive stresses that occur preferably takes over the concrete).
  • reinforcing bars as so-called Reinforcement meshes form and in the concrete involved. Acting in such reinforcement meshes it is welded reinforcing steel mesh that is made up of itself bars crossing at right angles are made up of which bars by shear-resistant welding with each other are connected. The raw material is cold rolled ribbed reinforcing bars with diameters from 4 mm to 12 mm.
  • Reinforcing bars are usually provided with ribs that also serve as visual identification. Smoothness and profiled (with little pronounced ribs) Reinforcing steels are only for special welded ones Reinforcement elements approved. Here are the Reinforcing bars or at least their ends with a Providing threads, this is called threaded steels.
  • FR-A 342078 which forms the closest prior art, the Connection of concrete bars shown with a connector.
  • the Connector has elongated holes in the area of abutments, which makes Connector over which reinforcing steel can be placed.
  • the reinforcing bars each have heads at their ends, which with the abutments of the Interact with the connector.
  • the disadvantage of this design is that to use this connector, the concrete parts that make up the Concrete bars protrude and the two heads of the concrete bars are extremely precise should be positioned to each other. Otherwise, for example with a too large a distance between the heads of the reinforcing bars, the connecting piece not placed over the ends of the reinforcing bars.
  • the connector according to the present Invention a relatively simple and clearly designed Has structure, it can perform the technical function connecting the ends of threaded steels convincing way to fulfill it as particularly surprising and for the expert in this Form can not be foreseen that the technical design of the invention it too allowed the ends of threaded steels to close together connect that are not exactly coaxial to each other are arranged. Furthermore, you will not lastly from the point of view of time and Cost savings appreciate that aforementioned connector a quick assembly allowed. Should be contrary to expectations point out that the assembly is not correct is done, it is in the present invention possible at any time by loosening the tightened Nuts to remove the connector again, to position and fix correctly.
  • Another decisive advantage of the present invention listed that the Distance between the ends of the threaded steels relative can be kept small since, as above explains the nuts before installing the Be screwed on. This The fact affects stability in particular for example of precast reinforced concrete slabs positive by the connectors according to the present invention are fixed to each other.
  • the connector as an elongated hollow cuboid part formed, both of which most distant end faces the abutments and its at least one, preferably two connecting the abutments Side surfaces define the connecting webs.
  • the simple and quick installation Tightening the nuts particularly favors if at least one, preferably two side surfaces the cuboid part between the abutments are recessed so that the nuts can be done by hand or are accessible with a ring spanner.
  • the width of the elongated holes is at least equal to the diameter of the threaded steels.
  • the width of the elongated holes slightly larger than the diameter of the threaded steels choose.
  • the latter technical measure serves the fact if necessary balance that the ends of the to be joined Thread steels are not completely coaxial with each other are arranged.
  • edges the connecting webs and the edges of the abutments to be flush with each other. This also facilitates warehousing and transportation of the connectors in a stacked form.
  • Forming the connector in particular inventive way is in the Corner areas between connecting bridge and abutment one nose each. These noses unfold their effect when the nuts after putting on the Connector are tightened, the lugs as Secure the nuts and prevent them from falling off or the connector slips off the ends prevent the thread steels.
  • the noses are expediently the recessed side surface of the cuboid part assigned to which recessed side surface the Elongated holes are open.
  • the noses in to form a rectangular shape.
  • the connecting webs of rectangular shape and / or the abutments are square in shape.
  • the connector shown in Fig. 1 is used the ends of threaded steels 10 and 12 together connect. This is the Threaded steels 10 and 12 um reinforcing bars that with are provided with a thread in the respective end areas nuts 60 and 62 can be screwed on.
  • the connector has two in here Connecting webs 20 and 22 extending in the longitudinal direction at the ends of each one of them Crosspieces 20 and 22 at right angles extending abutment 30 and 32 is arranged, each of which has a slot 40 and 42 has.
  • Fig. 1st Removable that the slot 40, the abutment 30 and the slot 42 is assigned to the abutment 32, the end of the threaded steel 10 in the abutment 30 (see also FIG. 2) and the end of the threaded steel 12 takes place in the abutment 32.
  • the connector shown in Fig. 1 is overall as an elongated hollow cuboid part trained, the two of which are farthest from each other spaced end faces (in Fig. 1 above and below) the abutments 30 and 32 and both of which the Abutments 30 and 32 connecting the side surfaces Define connecting webs 20 and 22.
  • the two side surfaces 24 and 26 are the two side surfaces 24 and 26 (see FIG. 2) of the cuboid part between the abutments 30 and 32 recessed, which means that in the representation of the Fig. 1 is a clear view of the ends of the Thread steels 10 and 12 with those on them screwed nuts 60 and 62 is made possible.
  • the person assembling the connector becomes it to avoid injuries during assembly especially appreciate that the edges of the Crosspieces 20 and 22 and the edges of the Close abutments 30 and 32 flush with each other, as for the abutment 30 as an example in FIG. 2 is shown.
  • the nuts serve 60 and 62 according to the locking of the connector of the present invention.
  • This is a total four tabs 50, 52, 54 and 56 in the corner areas between the connecting webs 20 and 22 and the Abutments 30 and 32 arranged, these noses 50, 52, 54 and 56 of the recessed side surface 24 of the cuboid part are assigned to which recessed side surface 24, the elongated holes 40 (cf. Fig. 2) and 42 are open.
  • These rectangular ones Noses 50, 52, 54 and 56 serve to secure the Nuts 60 and 62 when tightened and thus prevent the connector can fall or slip. It is about this is an additional effective one Security measure for the in Figures 1 and 2 shown embodiment of the connector is of great practical importance.
