Definitions

  • the invention relates to a dowel bar for shear reinforcement for reinforced concrete slabs, with a plurality of dowels arranged in parallel and at a distance from one another, each having a e.g. have plate-shaped widened dowel head and are attached at one end to a common dowel holding rail by means of at least one connecting piece formed on the end face.
  • Shear reinforcements made of dowel bars serve in plates or beams made of reinforced concrete in the area of support points, in particular in the area of column connections, to absorb the transverse forces occurring there as a result of the column forces and thus form a punching shear reinforcement.
  • the object of the invention is therefore to design a dowel strip of the type mentioned at the outset in such a way that it is easier, more cost-effective and more reliable, i.e. can be produced without impairing the functions of the dowel holding rail and / or dowels, but that a subsequent change by loosening individual dowels is excluded.
  • This task is done with a dowel bar. of the type mentioned generally solved in that the end connector of the dowel head by a cold molding process is deformed into a positive connection engagement with the dowel holding rail.
  • the positively received connector in the opening of the dowel holding rail is a rivet molded on the end face of the dowel head, which projects through the opening of the dowel holding rail and is riveted.
  • the rivet pin can be molded on in a simple manner and with only a small additional manufacturing effort.
  • the dowel holding rail is preferably provided with an opening as a hole or punching only at those points at which a dowel is to be arranged according to the static specifications.
  • the connection takes place in a simple manner by riveting the rivet plug inserted through the opening. The positive connection produced in this way cannot be detached subsequently, so that individual dowels cannot be removed.
  • the dowel holding rail is inserted into an end transverse groove of the dowel head and that the two end faces delimiting the transverse groove The edges of the dowel head are caulked to the side of the dowel holding rail.
  • the object on which the invention is based can, according to a further embodiment, be achieved in a simple manner in a dowel strip of the type mentioned at the outset without a special connecting piece in that the dowel holding rail in any case has openings at the spacing provided for the dowels has and the dowels are connected to the end of the dowel by means of welding spots provided in the openings.
  • the molding of an end-face connector on the dowels is therefore unnecessary.
  • the type of spot welding proposed also does not lead to any disadvantageous deformation of the dowel holding rail and to no reduction in the load-bearing capacity of the connection, as is the case with the above-mentioned welding known per se.
  • Another advantage is that the welding spots provided in the openings do not apply compared to the thickness of the dowel holding rail.
  • weld spots fill the openings in the dowel holding rail completely or substantially completely at the sides in order to further improve the absorption of forces.
  • the dowel holding rail for securing against rotation can be received in a front transverse groove of the dowel head.
  • the dowel holding rail is made from flat steel.
  • FIG. 1 shows a section of a dowel bar in a side view according to a first embodiment of the invention
  • FIG. 2 is an enlarged partial view of a dowel and a portion of the dowel holding rail according to FIG. 1 before assembly,
  • FIG. 5 shows another embodiment of the dowel bar in a section corresponding to FIG. 3,
  • the dowel bar 1 shown in Fig. 1 is used to build a shear reinforcement consisting of several such dowel bars in a reinforced concrete slab or a similar reinforced concrete part.
  • the dowel bar 1 consists of a dowel holding rail 2 and a plurality of dowels 3 arranged thereon at a distance and parallel to each other.
  • Each dowel.3 has an elongated dowel shaft 4 which can be smooth or provided with ribs. At both ends of the dowel shaft 4 there is a dowel head 5 or 6 widened in the manner of a plate a flat or substantially flat end face 11 is molded or welded onto the dowel holding rail 2 for contact.
  • the dowel holding rail 2 is a sheet metal rail consisting of flat steel and abuts the end face of the dowel heads 5.
  • an opening 7 is drilled or punched out of the dowel holding rail 2 (FIG. 2).
  • a connector 8 protruding from the end face 11 and formed as a rivet pin 8 'is formed, which is inserted through the opening during the assembly of the dowel bar 1 and provided with a rivet head 9 by riveting (FIG. 3).
  • transverse groove 10 can be provided in the end face 11 of the dowel head 5 in the region of the rivet pin 8 formed on the end face in order to prevent the dowel holding rail 2 accommodated in the transverse groove 10 from rotating.
  • the dowel holding rail 2 made of flat steel is inserted into the front transverse groove 10 of the dowel head 5. Then the edges 10a of the transverse groove 10 are caulked inwards so that they hold the dowel holding rail 2 in a non-detachable manner.
