  • the present invention relates to a bottom for a rope loop box with a cable feedthrough element for taking out an end of a rope loop from a rope loop box and with a rope holding member, wherein the bottom is designed so that in it a cable loop is receivable such that it between the cable feedthrough element and the cable holding member held at approximately right angles angled.
  • the invention also relates to a corresponding cable loop box.
  • Wire rope loops are used as connection anchors for connecting precast concrete elements. These connection anchors can also serve to transport the components.
  • the rope loops known from the prior art are produced by connecting the ends of a steel cable section together in such a way that a rope eye is formed.
  • the ends of the cable loop are firmly embedded in a precast concrete part, wherein the cable eye of the loop protrudes from the precast concrete part, so that it can be used as an anchor for connection to another precast concrete part or for receiving a crane hook or transport harness. It is expedient and advantageous if during the transport of the precast concrete part and especially during the extrusion or casting of the part, the cable loop does not protrude beyond the dimensions of the precast concrete part.
  • rope loop boxes which receive the rope loops during the manufacture of the precast concrete part as well as during transport.
  • the rope loop boxes of the prior art are boxes made of sheet metal with a lid, which are poured into the precast concrete, so that after the production of precast concrete, the lid of the rope loop box flush with an outer surface, ie usually the front side of the precast concrete part.
  • the cable loop is received in the cable loop box so that the cable eye is held in the cable loop box substantially at a right angle with respect to the cast into the precast concrete section of the cable loop.
  • the lid of the rope loop box is replaced and relaxed the cable loop from its angled position and placed in a position in which it protrudes substantially perpendicularly from the outer surface of the precast concrete part.
  • holding elements are provided in addition to the molded part for forming a bending stop in the prior art holding the cast with the precast concrete rope loops in an angled condition.
  • the holding elements are usually also introduced as additional moldings in the rope loop box.
  • the present invention has the object to provide a simple and inexpensive to manufacture rope loop box.

  • Such a configuration is advantageous because it allows the production of the bottom of a rope loop box in a single operation with only a single processing technique. It is expedient if the floor according to the invention and preferably also the other elements of the cable loop box made of plastic or other injection or deep drawable material, preferably by means of injection molding.
  • a corresponding bottom is typically substantially rectangular.
  • the floor is further characterized in one embodiment in that the rope feedthrough element has a support portion.
  • the preferred embodiment of the plastic rope loop box according to the invention is advantageous because it makes it possible to design the rope loop box such that it is substantially closed. It is understood by “substantially closed” that the rope loop box except the openings for receiving the ends of the cable loop, which are cast in the precast concrete part, has no openings except the lid opening. In this way it is prevented that in the manufacture of precast concrete enters the interior of the rope loop box, which hinders the folding out of the rope loop when mounting the precast concrete part.
  • the cable feedthrough element has an opening through which a cable section of a cable loop can be brought out of the cable loop box.
  • the rope feedthrough element at least in sections has such a wall thickness that thereby a support portion is formed for a led out of the rope loop box rope section, so that the cable loop is receivable in the angled state in the rope loop box.
  • Such an embodiment of the cable loop box according to the invention is advantageous because it allows, despite the integral design of the cable loop box, that the ends of the cable loop protrude substantially at right angles from the bottom of the cable loop box, even if the cable eye at right angles to be cast with the concrete element End of the rope loop is angled. The forces of the rope loop are then removed from the support sections, i. the walls of the openings in the feedthrough element, intercepted.
  • the cable feedthrough element at least around the opening for receiving the cable section around an increased thickness of 3 mm to 10 mm, preferably of 5 mm.
  • the height of the rope loop box determines how far extends the attached to the formwork of precast concrete box in the shape of the concrete part. If the box is high, the forces acting on it as the concrete flows into the mold are also high and may tear the box off the formwork. Therefore, a height of the rope loop box of 10 mm to 30 mm, preferably 15 to 25 mm, and more preferably 20 mm is appropriate.
  • a rope loop box having a height in the aforementioned ranges allows to provide reinforcements in the concrete part having a concrete cover of only 30 mm without constructively altering the reinforcement around the rope loop boxes.
