Definitions

  • the invention relates to a device for connecting prefabricated concrete parts, consisting of at least one rope loop, the is anchored at one end in the precast concrete and their other, loop-like end with one in the end face of the Precast concrete used interacts to the Rope loop during the manufacture of the precast concrete part bend elastically at a right angle and release it for the bond.
  • a device of the type indicated above is for example made known by DE-A-16 84 254.
  • the other part is in the holding part fixed and can be erected to produce the position of use become.
  • the rope loop is fixed in the holding part thereby by a nose-shaped approach in the middle plane of the Holding part.
  • Similar devices are in EP-A-0 534 475 and described in DE-A-4 131 956.
  • Devices of the type in question are about one Arrangement to be made such that during the manufacture of the Precast concrete and the rope loop during transport or a similar element does not have the outer dimensions of the Precast concrete protrudes to rule out that the rope loop or the like hinders transportation or stacking is.
  • EP-A-0 534 475 another device for the in Described purpose described.
  • the rope loop without mechanical Strain on the insert elastically deforming and at least fixed essentially at right angles.
  • the invention has for its object a device to further develop the genus described at the beginning, that it is easy and inexpensive to manufacture, with the Process no interference should occur and where the Rope loop in the connecting position with simple means can be brought.
  • the invention is based on the device of the genus specified at the beginning and suggests that the holding part as an elongated, in cross section essentially uniform, U-shaped box is formed, the im essentially flat box bottom, which is parallel to the end face of the precast concrete, an opening for the rope loop has, with means in the area of the opening, essentially the part of the rope loop to be anchored hold at right angles to the length of the box, with elongated in the edge area of the legs of the U's Holding elements that hold the bent rope loop in the box hold, but disengage the rope loop from the stop position allow.
  • the invention achieved by a simple component, namely the essentially U-shaped box, an arrangement that is easy in the formwork for the production of the precast concrete part can be arranged.
  • the dimensions, especially at right angles to End face of the precast concrete are small, so that in the Usually there is no fear of collision with other reinforcement parts is.
  • the box is sufficiently stable to withstand the bending forces to record. There are none for the disengagement process special tools necessary.
  • the opening provided by the invention in the box bottom is generally bounded on all sides by the bottom of the box.

  • a sealant the gap between the rope loop and opening closes.
  • a plastic sealant for example, is used existing molding proposed, which as below still described, held by the box. It is also possible between the inserted rope loop and the box a glue, for example one Apply drops of glue, synthetic resin or the like on the one hand, a mechanical fixation of the rope loop in terms of the box and the remaining one at the same time Closes the gap in such a way that no concrete penetrates. In the same way, it is also possible that foaming is used.
  • the sealants are used here, for example also chosen so that they do not absorb any bending forces means when bending the rope loop, especially if the rope loop is inserted in the box, no bending forces pick up or support the bend. This can lead to Example by appropriate arrangement of the molded part in or can be reached at the storage box. The use of glue or foaming agent only closes the remaining one Split, but these funds do not take over Abutment functions with regard to the bending forces that occur.
  • the molded part is designed so that it closes the gap between the rope loop and the opening.
  • the molding thereby prevents that when concreting Concrete penetrates inside the box, causing the later Erection of the rope loop could be hindered.
  • the molded part can have different designs. It can For example, have a flange that abuts the bottom of the box. In this or in other embodiments provided that the molding and the opening of the Rotational symmetry deviate to the inserted part to fix a rotary movement in the opening. If both Parts, i.e. the molded part and the opening, for example are oval, the molded part can be easily inserted. A breakthrough results in a secure connection especially through the use of flanges or similar means.

  • the molded part inserted parallel to the longitudinal extent of the box bottom.
  • the molded part can then, if desired, also with interact with the side walls of the box.
  • the agent that the anchoring rope loop part essentially perpendicular to The box extends longitudinally, in one piece as a turn connected to the box.
  • Such a configuration achieved a very simple manufacture of the box in which the bending absorbing the bending forces already in one piece is integrated.
  • Such an embodiment can, for example can be achieved by an appropriate punching process.
  • the box bottom inside and / or outside a holding means has that the molded part in the area of the opening holds.
  • the molded part only has the function of the calculation, which serves as a turn, for example, as far as again to close that in the remaining gap between opening and carried out rope rope no concrete in the Box can shrink.
  • the holding means become Example also at the same time as making the turn or breakthrough generated. This can be the case with Manufacturing process done by an appropriate punch. For example, an upright is used as a holding device Tab of the box bottom used. In the manufacture of the Box, for example made of plastic, will be a corresponding one Design of the box using an appropriate injection mold reached.
  • the holding means can both Storage box, as well as on the underside of the storage box against the precast concrete. On Both places, it is possible to use an appropriate sealant to attach and fix this with the holding means.
  • the holding elements are preferably by at the edge of the Legs of the U's formed inward ledges. This Lasts can be obtained, for example, by bending become.
  • the strips preferably extend over the full length of the box, creating a substantial stiffening of the box is obtained, although the effect as holding elements only necessary in a narrow area for the rope loop would. Therefore, there are also individual holding elements in the Box interior possible to hold back the rope.
  • the width of the strips should be equal to or greater than that Half the diameter of the wire rope of the rope loop. On this way, a secure hold for the inserted rope loop receive. However, there is still enough space between the slats to the rope loop after moving the precast concrete to be able to erect.
  • the box is provided with end covers, for example are obtained by bending. Such training is particularly recommended if the box is made of sheet metal is made. In this way, a one-piece Construction are obtained with a high degree of rigidity low manufacturing costs.
