Definitions

  • the invention relates to a device with a reinforced concrete reinforcement basket according to the preamble of claim 1 and to a method for producing a reinforced concrete reinforcement basket according to the preamble of claim 14.
  • the invention has for its object to develop a particularly inexpensive and material-saving producible reinforced concrete reinforcement basket and to provide a method for producing such a reinforced concrete reinforcement basket, without affecting a stability of the reinforced concrete reinforcement basket. It is achieved according to the invention by the features of claims 1 and 14. Further embodiments emerge from the subclaims.
  • the invention relates to a device having a reinforced concrete tubbing basket for a tubing in an arc segment shape with at least one reinforcing element extending over a length of the reinforced concrete tubing basket in a circumferential direction with respect to the arc segment shape.
  • the reinforcing element is bent from the circumferential direction at at least one angle in a radial direction with respect to the arc segment shape.
  • circumferential direction should be designated a circumferential direction of an imaginary, the arc segment shape of the tubbing continuing circle.
  • the circumferential direction corresponds to a longitudinal direction of the tubbing. Accordingly, the term “radial direction” refers to the radius of this circle.
  • Generic reinforcing elements are usually rod-shaped, with a round cross-section and made of steel.
  • an "angle" is to be understood as meaning a bent region of the reinforcing element having a radius of curvature determined according to DIN 4088, provided that the curved region has a radius of curvature which is many times, in particular more than ten times, smaller than a radius of curvature of the arc segment shape of reinforced concrete reinforcement basket.
  • the diameter of the steel is determined by the static requirements.
  • a reinforcing element should also be designated if it extends over a greater proportion of the length, for example over 90%, but at least over 50% of the length.
  • the reinforcing element is bent in at least two angles of about 90 °.
  • the reinforcing element can assume a particularly good support function in the radial direction and / or can have an integrally formed, statically advantageous overlap region.
  • an angle of "about" 90 ° should be referred to in this context angles that differ by less than 20 ° from 90 °.
  • Embodiments of the invention are particularly advantageous in which the device comprises at least one U-shaped stirrup element terminating the reinforced concrete tubing basket in the circumferential direction and formed integrally with the reinforcing element.
  • a separate, U-shaped bracket member can be advantageously eliminated and labor and material costs associated with the welding of the bracket member with the reinforcing element, can be saved without affecting stability of the reinforced concrete reinforcement basket.
  • the bracket elements can be saved on both sides, if the reinforcing element is formed integrally with two, in each case integrally formed on one end of the reinforcing element, U-shaped bracket elements.
  • the reinforcing element can also form a closed curve, which completely surrounds the reinforced concrete tubing basket in the circumferential or longitudinal direction, and which delimits a surface of a segment of a circular ring.
  • the reinforcing element spans the length of the reinforced concrete reinforcement cage several times in the circumferential direction.
  • the reinforcing element can also be a closed, the reinforced concrete reinforcement basket in the circumferential form a longitudinally encompassing curve which forms the surface of a segment of a circular ring.
  • the reinforcing element spirally wraps around the reinforced concrete reinforcement basket in the circumferential direction.
  • the device comprises at least one distribution iron with an integrally formed angle. As a result, separate angle elements for connecting two distribution bars can be omitted.
  • the device comprises at least two reinforcement elements running in a circumferential direction with respect to the arc segment shape over a length of the reinforced concrete baffle basket, which are connected by at least one transverse reinforcement element, it is possible to dispense with assembly rods for connecting the reinforcement elements at a defined spacing in a cost and material-saving manner.
  • the device comprises a one-piece transverse reinforcement element of the reinforced concrete reinforcement basket, which spans a width of the reinforced concrete reinforcement basket at least twice, a particularly simple and cost-effective transverse reinforcement can be achieved.
  • the transverse reinforcement element can wrap around the reinforced concrete reinforcement basket in a particularly advantageous manner in the transverse direction in a spiral shape.
  • a "transverse direction” is to be understood as an axial direction with respect to the arc segment shape.
  • a stress-free reinforced concrete reinforcement basket can be achieved if the reinforcement is arched pre-bent into the reinforced concrete reinforcement basket.
  • a pre-bending operation can be omitted in an advantageous and cost-saving manner if the reinforcing element is installed in a bow-shaped biased manner into the reinforced concrete reinforcing basket.
  • the invention is based on a method for producing a reinforced concrete reinforcement basket for a tubbing in an arc segment shape with at least one reinforcement element which extends over a length of the reinforced concrete reinforcement basket in a circumferential direction with respect to the arc segment shape.
  • the reinforcing element is bent before welding with other reinforcing elements from the circumferential direction at least at an angle in a radial direction with respect to the arc segment shape. As a result, it is possible to dispense with welding radial support elements of the reinforced concrete reinforcement basket.
  • the invention is based on a method for producing a Stahl statisticsübbingarm istskorbs for a tubbing in an arc segment shape with at least two reinforcing elements.
  • the reinforcing elements are connected on a jig by at least one transverse reinforcement element. Thereby, a pre-assembly step for connecting the Reinforcement elements omitted before application to the teaching.
