Definitions

  • the invention relates to a method for producing a reinforcing cage for reinforced concrete components, with a longitudinal reinforcement, if necessary, to be attached to stiffening rings and a holding wire or spiral arranged around it in a spiral.
  • the invention further relates to an auxiliary or support structure for performing the method.
  • Reinforcement baskets for reinforced concrete components and their manufacture have become known from US Pat. No. 4,377,928 or from German Pat. No. 30 00 605. This is done in that the longitudinal bars forming the longitudinal reinforcement are attached to stiffening rings arranged at an axial distance in order to form a basket frame. The spiral holding wire or the spiral is then attached to the frame and wound up by rotating the basket about its longitudinal axis at the predetermined distance (pitch). The spiral can then be braided or welded to the longitudinal bars. The spiral is cut off at the end of the basket and welded onto the last stiffening ring.
  • the present invention has for its object to eliminate the aforementioned disadvantages and to provide a method in connection with an auxiliary device with which the manufacture of reinforcement cages can be greatly simplified.
  • the device according to the invention is based entirely on the conventional manufacturing principle of reinforcement baskets.
  • the previous manufacturing process is rather pulled from behind, d. H.
  • First the spiral is to be produced, which in turn serves as a support for the longitudinal reinforcement to be fastened. Any necessary stiffening rings for larger reinforcement baskets are only inserted into the basket at the end.
  • the invention is based on the idea that an extremely stable basic structure must be available for winding the spiral, which is not guaranteed by the longitudinal reinforcement of the reinforcement cage with stiffening rings alone. Proceeding from this, it is therefore proposed according to the invention that a separate, stable auxiliary scaffold or support scaffold be used, on which the spiral can be wound up without problems and in the correct shape. Only then is the longitudinal reinforcement and other devices such as stiffening rings etc. attached to the spiral or to the longitudinal reinforcement.
  • the essence of the invention is therefore to carry out the production of reinforcement cages by means of an auxiliary device which is removed again after the production of each reinforcement cage.
  • This is done according to the invention in that the outer diameter or the lateral surface formed by the auxiliary frame around which the spiral is wound is reduced after manufacture so that the auxiliary device can be pulled out of the reinforcement cage again.
  • the invention is described in two embodiment variants, which are shown on the one hand in FIGS. 1 to 6 and on the other hand in FIGS. 7 to 9.
  • the reinforcement cage 10 shown in FIGS. 1 to 3 consists of the longitudinal bars 11 forming the longitudinal reinforcement and the spiral 12 arranged around it, which is wound at a certain pitch.
  • the longitudinal rods 11 are fastened to the spiral by means of a wire fastening 13 or the like.
  • An auxiliary scaffold or supporting scaffold is used to produce the reinforcement cage, as shown in FIGS. 4 to 6 without the reinforcement cage to be produced, and is shown in FIGS. 1 to 3 with the reinforcement cage.
  • the auxiliary scaffold or support scaffold 14 according to the first embodiment variant according to FIGS. 1 to 6 consists of a tube piece 15, for example of approximately 20 cm in length.
  • the divided pipe section 15 has a hinge 16 on one side, while it is shortened by an amount s in the lateral surface on its side opposite the hinge 16.
  • a wedge 18 engages in this axial longitudinal slot 17, which gives the tubular piece 15 the cylindrical outer contour.
  • the wedge 18 is designed to be pivotable about a joint 19 so that it can pivot into the tube piece, releasing the longitudinal slot 17.
  • one (see FIG. 4) or two (see FIG. 1) wedges can be provided.
  • the pipe section 15 is shown with the wedge 18 introduced into the longitudinal section 17, in the
  • the wedge 18 is removed from the longitudinal section 17 so that the pipe section 15 can reduce its outer diameter D to an amount D 'by means of the hinge 16. This is as much as the longitudinal slot 17 can merge.
  • auxiliary frame 14 On the pipe section 15 of the auxiliary frame 14, longitudinal pipes 20 are welded (welded connection 21), which have a length like the reinforcement cage to be produced, for example 6 m. However, the length can be increased by simply plugging together such auxiliary scaffolds. Shorter auxiliary scaffolds can also be used which, when plugged together, form a greater length.
  • the pipe sections 15 are arranged, for example, at a distance of approx. 1 m within the auxiliary scaffolding, so that with an auxiliary scaffolding of approx. 6 m in length, approximately seven pipe sections 15 are present at a uniform distance as a pipe support.
  • the pipe sections 15 are only made as large as is necessary for the stability of the auxiliary scaffold 14. This also applies to the diameter or the thickness of the tubes 20, which can have a diameter of 25 to 30 mm, for example.
  • the longitudinal rods 11 forming the longitudinal reinforcement are provisionally attached to the auxiliary frame 14.
  • the holding wire 23 is wound helically with a special device, so that a spiral 24 is formed.
  • the longitudinal bars 11 forming the longitudinal reinforcement are fastened to the spiral 12 by means of a wire connection 13.
  • the auxiliary scaffold 14 can then be reduced in diameter D 'to a smaller amount d' by knocking the wedge 18 out of the axial longitudinal slot 17 (see FIG. 3), so that the auxiliary scaffold 14 can be pulled out of the interior of the reinforcement cage without problems .
  • the wedge 18 pivots into the interior of the auxiliary frame 14 by means of the joint 19.
  • the gap 17 closes in the process.
  • the device according to the representation according to FIGS. 1 to 6 is preferably designed as an auxiliary scaffold for root piles and smaller supports.
  • the outer diameter D formed by the lateral surface around the longitudinal tubes 20 of the auxiliary frame 14 must correspond to the desired inner diameter of the spiral 24. This diameter can be approximately 16 cm, for example.
  • the introduced longitudinal rods 11 can have a diameter of 14 to 28 mm, for example.
  • the diameter of the tubes 20 is selected, for example, 25 to 30 mm so that the longitudinal rods 11 have enough space in the spaces 22 between two tubes 20.
  • the auxiliary scaffold shown in FIG. 8 also consists of longitudinal tubes 20, which for example have a length of approximately 6 m.
  • a star-shaped support cross 25 or support cross is provided in this embodiment, which also z. B. is arranged at a distance of 1 m in the auxiliary frame 26.
  • the support cross or support cross 25 consists of four radially extending tubes 27, which are crossed in a star shape and into which extension tubes 28 are inserted axially.
  • the longitudinal tubes 20 are welded on. The radial position of the extension tubes 28 within the tubes 27 is determined by a split pin connection 29.
  • the spiral can then be wound around the auxiliary frame 26 in a diameter D. Thereafter, the longitudinal rods 11 previously arranged in the space between the tubes 27 are again fastened to the spiral. Finally, the split pin connections 29 are loosened, as a result of which the inserted extension tubes 28 slide into the tubes 27 and thus reduce the diameter D, in order in turn to be able to pull the auxiliary scaffold out of the finished reinforcement cage. Stiffening rings are inserted into the reinforcement cage and attached after the auxiliary scaffolding has been removed.
  • the invention is not restricted to the exemplary embodiment shown and described. It also includes all professional modifications and developments of the features and measures described and / or shown.
  • round, oval or other reinforcement baskets can be produced for all types of reinforced concrete parts.
  • large bored piles and supports in which the reinforcement is placed in boreholes and these are then poured out with concrete, driven piles or similar supports can also be manufactured.
  • the decisive factor is the use according to the invention of a supporting scaffold or auxiliary scaffolding for the production of a spiral, which is only then produced to form a reinforcing basket or the like.
