Definitions

  • the present invention relates to a prefabricated reinforcing element for the construction of concrete structures, in particular for civil engineering, consisting of several U-shaped reinforcing bars which are connected to one another by means of longitudinal connecting bars.
  • Prefabricated reinforcement elements have become more and more widespread in recent years, particularly as a result of the work of the applicant. Such reinforcement elements are mainly used in building construction.
  • a prefabricated reinforcing element of the type described at the outset is known in particular from CH-PS 642'131. It is a simple basic element consisting of several U-shaped arches Reinforcing irons which are connected to one another by means of a plurality of longitudinal connecting irons, two of the three identical sides of all U-shaped reinforcing irons being welded to at least one longitudinal connecting iron. This guarantees the element the desired bending stiffness.
  • These known reinforcement elements are suitable for creating precisely straight concrete components. Such elements are mostly used in the construction of masonry.
  • the present invention therefore has as its object to provide a prefabricated reinforcing element which can be bent as desired in one plane, while at the same time the U-shaped reinforcing bars regularly align in the desired direction.
  • the reinforcement elements according to the invention are used to create curved, curved or arched concrete structures.
  • all design variants consist of a plurality of U-shaped reinforcing bars 1 and at least two, preferably wise, however, three, the U-shaped reinforcing bars interconnecting longitudinal rods 2.
  • the length relationships of the two parallel legs 10, 11 and the base 12 are different. It is essential, however, that the longitudinal connecting bars 2 are all attached to the same leg of all U-shaped reinforcing bars 1 or all to the base 12. Another, generally valid feature can be seen in the fact that the longitudinal connecting bars 2 are relatively close to one another. Thus, all longitudinal links 2 are in one plane E1.
  • the prefabricated reinforcing element can therefore not be bent, but the element can be deformed perpendicular to the plane E1, in the plane E2 in which, for example, the base 12 of the U-shaped bracket 1 is located.
  • the element can thus be bent in the horizontal direction, whereas in the vertical direction it is resistant to bending.
  • FIG. 1 shows an element which consists of equilateral U-shaped brackets 1, in which the left legs 10 of all U-shaped reinforcing bars 1 are connected to one another by three parallel longitudinal connecting bars 2.
  • a rectangular shaft can be designed, which is bent as desired in one plane (FIG. 5).
  • FIG. 2 shows an element, which has a hairpin-shaped, isosceles, U-shaped reinforcing iron 1 '.
  • the longitudinal connecting iron 2 ' are welded to the end portion of the leg 10'.
  • Such reinforcement elements can be used, for example, to create curved wall crowns.
  • FIG. 6 shows an application of such elements for creating a channel open on one side.
  • the longitudinal connecting iron 2 ⁇ can also be welded to the lower narrow side of the base of the U-shaped bracket 1 ⁇ .
  • the two legs 10 ⁇ , 11 ⁇ can have different lengths.
  • Two mirror-inverted elements according to FIG. 3 can be used, for example, for the creation of the curved foundation slabs in one plane. No such application example is shown in the drawing.
  • FIG. 4 A last exemplary embodiment is shown in FIG. 4.
  • the base 12 is very wide here and the longitudinal connecting bars 2 are all located on one of the two short legs 10.
  • the legs 10 and 11 are directed against one another in their end region by 90 °.
  • Such an element can be used, for example, together with one or two elements according to FIG. 2 to form a building that is curved in one plane, in which two perpendicular concrete surfaces occur, as shown in FIG. 6.
  • the same element in FIG. 4 is bent in an S shape in FIG. 7 and drawn in a laying plan.
  • the individual U-shaped reinforcing bars 1 are thus always automatically aligned with the center M of the bend.
  • the distance between the two outermost, parallel longitudinal connecting bars is at a maximum distance of 20 cm.
