Definitions

  • the invention relates to a connector for connecting the ends of threaded steels.
  • reinforcing steels are often used, which are used, for example, in precast reinforced concrete slabs, such as are common in the manufacture of so-called solid carriageways for high-speed rail traffic.
  • the reinforcing bars are inserted into the concrete as reinforcement and serve to absorb the tensile forces and transfer them to the concrete (the compressive stresses that occur are preferably taken over by the concrete).
  • Reinforcement meshes of this type are welded reinforcing steel meshes which consist of bars crossing at right angles, which bars are connected to one another in a shear-resistant manner by resistance spot welding.
  • the raw material is cold rolled ribbed reinforcing bars with diameters from 4 mm to 12 mm.
  • the surfaces of the reinforcing steels are usually provided with ribs, which also serve for visual identification. Smooth and (with little pronounced ribs) profiled reinforcing steel are only permitted for special welded reinforcement elements. If the reinforcing steels or at least their ends are threaded, this is referred to as threaded steels.
  • connecting pieces are known from the prior art for connecting the ends of such threaded steels.
  • these connecting pieces can usually only be used for a certain type of threaded steel, problems having often arisen in the past, for example in the case where the ends of the threaded steels to be connected are not completely coaxial with one another.
  • the known connectors are also of complicated and therefore expensive construction and are difficult to assemble.
  • the present invention is based on the object of providing a connecting piece for connecting the ends of threaded steels which can be assembled quickly and easily by simple mechanical measures. Furthermore, the present invention aims at a connecting piece for connecting the ends of threaded steels which can be used in a wide and flexible manner, and this is also the case Consideration should be given to the fact that the ends of the threaded steels to be connected are not completely coaxially oriented.
  • a connecting piece for connecting the ends of threaded steels which has at least one, preferably two connecting webs extending in the longitudinal direction, at the ends of which an abutment extending at right angles to these connecting webs is arranged, each of which has a one-sided open one Has elongated hole.
  • the connecting piece is designed according to the invention in the aforementioned manner, the elongated holes open on one side in the abutments extending at right angles to the connecting webs enable the connecting piece to be placed directly over the ends of the threaded steels and over the nuts previously screwed onto the ends of the threaded steels. The nuts are then tightened by hand or with a suitable ring spanner.
  • the connector according to the present invention has a relatively simple and clearly designed structure, it is able to perform the technical function of connecting the ends of threaded steels in a convincing manner, it being particularly surprising and unpredictable in this form for the person skilled in the art that the technical design of the invention also allows the ends of threaded steels to be connected to one another which are not arranged exactly coaxially with one another. Furthermore, you will not Lastly, from the point of view of saving time and costs, appreciate that the aforementioned connector allows quick assembly. If, contrary to expectations, it turns out that the assembly has not been carried out correctly, it is possible with the present invention at any time to remove the connecting piece again by loosening the tightened nuts, to position it correctly and to fix it again.
  • the connecting piece is designed as an elongated, hollow, cuboid-shaped part, the two most distant end faces of which define the abutments and whose at least one, preferably two, side faces connecting the abutments define the connecting webs.
  • the simple and quick assembly by tightening the nuts is particularly favored if at least one, preferably two side faces of the cuboid part are recessed between the abutments, so that the nuts are easily accessible by hand or with a ring spanner.
  • the elongated holes are open towards one of the recessed side faces of the cuboid part, so that the connecting piece can easily be placed on the ends of the threaded steels and subsequently the nuts are tightened, for example, with a suitable ring spanner can be.
  • the width of the elongated holes is at least equal to the diameter of the threaded steels. To compensate for slight tolerances, it may be advisable to choose the width of the elongated holes slightly larger than the diameter of the threaded steels. The latter technical measure also serves to compensate for the fact that the ends of the threaded steels to be connected are not arranged entirely coaxially with one another.
  • the connecting piece according to the present invention gives the elements to be connected a particular stability when the length of the elongated holes is approximately equal to half the height of the abutment, because in this case both the tensile stresses and the compressive forces are distributed uniformly over the connecting piece.
  • a nose is arranged in the corner regions between the connecting web and the abutment.
  • These lugs have their effect when the nuts are tightened after the connection piece has been put on, the lugs serving as securing means for the nuts and preventing the connection piece from falling off or slipping off the ends of the threaded steels.
  • the lugs are expediently assigned to the recessed side surface of the cuboid-shaped part, to which recessed side surface the elongated holes are open.
  • connecting webs are rectangular in shape and / or the abutments are square in shape.
  • FIGS. 1 and 2. It shows:
  • Figure 1 is a bottom view of an embodiment of a connector for connecting the ends of threaded steel according to the present invention.
  • FIG. 2 shows a view of an end face of the example from Fig. 1st
  • the connector shown in Fig. 1 is used to connect the ends of threaded steels 10 and 12 together.
  • the threaded steels 10 and 12 are reinforcing steels which are provided with a thread onto which nuts 60 and 62 can be screwed in the respective end regions.
  • the connecting piece here has two longitudinally extending connecting webs 20 and 22, at the ends of which an abutment 30 and 32 extending at right angles to these connecting webs 20 and 22 is arranged, each of which has an elongated hole 40 and 42 that is open on one side. 1 that the elongated hole 40 is associated with the abutment 30 and the elongated hole 42 is associated with the abutment 32, the end of the threaded steel 10 in the abutment 30 (cf. also FIG. 2) and the end of the threaded steel 12 takes place in the abutment 32.
  • the connecting piece shown in FIG. 1 is designed overall as an elongated hollow cuboid-shaped part, the two most distant end faces of which (above and below in FIG. 1) are the abutments 30 and 32 and the two side faces connecting the abutments 30 and 32 are the connecting webs 20 and 22 define.
  • the two side faces 24 and 26 (cf. FIG. 2) of the cuboid part are recessed between the abutments 30 and 32, which in the representation of the Fig. 1 allows a clear view of the ends of the threaded steels 10 and 12 with the nuts 60 and 62 screwed thereon. It can be seen from the illustration in FIG.
  • the elongated hole 40 is open towards the recessed side face 24 of the cuboid part.
  • the elongated hole 42 is of course also open to the recessed side surface 24 of the cuboid part.
  • the width of the elongated holes 40 and 42 in the embodiment shown in FIGS. 1 and 2 is slightly larger than the diameter of the threaded steels 10 and 12. This enables a simple and problem-free placement of the connecting piece on the ends of the threaded steels 10 and 12, before the connecting piece is then locked by tightening the nuts 60 and 62. 2 that the length of the elongated hole 40 is approximately equal to half the height of the abutment 30, which gives the connector a particularly good mechanical stability. The aforementioned dimensioning naturally applies in the same way to the elongated hole 42.
  • the person assembling the connecting piece will particularly appreciate that the edges of the connecting webs 20 and 22 and the edges of the abutments 30 and 32 are flush with one another, as exemplified for the abutment 30 in FIG. 2 is shown.
  • nuts 60 and 62 serve to lock the connector in accordance with the present invention.
