Definitions

  • the climbing elements When manufacturing concrete shaft pipe elements with vibrated climbing elements or crampons, the climbing elements must be inserted into the mold core before the filling and compression process so that they can be clamped there.
  • the mandrel for loading with climbing elements is moved upwards from the machine pit over the corridor, so that the climbing elements can be inserted without additional gripping devices and without climbing stairs.
  • the technical effort for this is relatively large, since the entire mandrel with vibrating device must be built in a height-adjustable design. Due to the required accuracy of fit, the precision required for the guides is very high. Large mass forces must also be overcome. Furthermore, a correspondingly large free space must be created for mold cores with a height of approx. 2 m above the machine.
  • the lower risers can only be inserted here by bending over the operator.
  • a device known from DE-PS 35 07 270 has the advantage that only small masses have to be moved when inserting the climbing elements.
  • a loading basket with crampons is moved in the horizontal direction until it is in alignment with the mold space and then lowered into the mold space.
  • the lowered loading basket then transfers the crampons to the holders.
  • the loading basket is then moved upwards out of the molding space and moved away to the side.
  • the mandrel can remain in a stationary design. Any designs of riser elements can be inserted into the loading basket and inserted into the mold core.
  • This device has also proven itself when more than two climbing elements are inserted.
  • the invention has for its object to develop a device of the generic type that significantly simplifies conventional manual insertion with low investment costs; in particular, the insertion of the reinforcement parts should be made easier with very high cores; it should also be possible for the operator to be able to reach the floor level after inserting the reinforcement parts, in particular crampons, i.e. not during the completion of the mold cavity, during filling and during shaking if there is a corresponding risk in the pit.
  • a height-adjustable platform for an operator is arranged in the area surrounding the mandrel in the shaping position of the molded part support along the height of the mandrel in insertion positions to the different brackets can be moved.
  • the operator can drive down or then up along the mold core located in the pit and then up again, taking the reinforcement parts, hereinafter referred to as crampons, with him and either during the downward movement or during the Insert upwards into the brackets in the mandrel.
  • the stroke and the individual standstill stations in the course of the stroke can be selected so that the operator can insert the crampons standing or sitting without bending down or other body contortions.
  • the platform is adjustable in height between a lowering position, which is at or below the level of the lowest crampon in each case, and a raised position, which is at least approximately at floor level. If crampons are to be laid to the lower end of the respective concrete part, it can be provided that the platform is in its lowered position at the level of the molded part support in the shaping position or below.
  • the platform can be locked in at least one intermediate position between the lowered position and the raised position.
  • the platform is equipped with a moving control switch for controlling its lifting or lowering movement.
  • control switch is a foot switch.
  • a crampon support In order to save the operator from having to bend over crampons lying on the platform, it is possible for a crampon support to be arranged on the platform.
  • This carrier can be arranged at the operator's hand height and is measured in height according to whether one wants the operator to work in a sitting or standing position.
  • the platform can be height-adjustable by means of a fluid-operated power device, in particular a lifting press.
  • the molded part support can be height-adjustable by a separate, in particular a further fluid-actuated, power device from the power device of the platform.
  • an intermediate storage for crampons can be arranged in close proximity to the platform.
  • This intermediate storage can in particular be arranged in such proximity to the platform that the operator can remove crampons from the intermediate storage from the platform.
  • any further control elements for controlling the operating sequence of the device can be arranged on the platform or in an area which can be reached by the operator located on the platform is.
  • the mandrel must be serviced regularly. In order not to hinder maintenance by the platform, it is provided that the platform is guided on a vertical guide which is arranged on or near a lateral boundary of a pit which accommodates the mandrel.
  • the guide can be accommodated in such a way that the vertical guide is arranged between the bottom of the pit and a covering overhang of the pit.
  • a power device with an upper one of two parts which are movable relative to one another is fixed on the underside of the covering projection and with the other of its movable parts acts on a guide carriage of the platform.
  • a particularly favorable design with regard to the maintenance of the mandrel results when the platform can be folded from a substantially horizontal operating position into a substantially vertical non-operating position.
  • a pit 10 can be seen, which is arranged sunk relative to the corridor level 12.
  • a mold core 14 can be seen in this pit.
  • the mold core 14 is equipped with devices for holding crampons 16.
  • the German patent 31 10 185 C3 on FIG. 1 and the associated description in column 4, line 46, to column 12, line 66, are referred to.
  • the mandrel 14 is stationary on the bottom of the pit 10 by a stand 18.
  • the mold core is surrounded by an annular molded part support 22, on which sub-sleeves 23 are placed for each individual concrete part.
  • the molded part support 22 can be adjusted in height by a power device 25.
  • a shaped jacket is arranged concentrically to the mandrel 14 and is also height-adjustable by means of a further power device 26.
  • the shaped jacket 24 is not yet in its highest position. It must be possible to move it upwards so far that its distance from the floor level 12 is greater than the height of the mold core 14. Inside the mold jacket 24 one recognizes a fold formation ring 28 which is intended to rub a fold into the upper end of the resulting concrete part.
  • the molded part support 22 is first lowered into the position shown in FIG. 1 by means of the power device 25.
  • a lower sleeve 23 is placed on the molded part support 22 before the lowering begins, which can be designed as a folded ring.
  • This sub-sleeve forms part of the shaping surfaces, namely it forms the lower shaping surface for the concrete part. It remains on the concrete part after it has been removed from the mold until the concrete part is essentially completely hardened.
  • the lower sleeve 23 allows the molded part to be handled after it has been separated from the mold core 14 and the molded jacket 24.
  • the lower sleeve 23 comes to rest on a support ring surface 27 which is arranged in a stationary manner with respect to the molded core and remains on the latter while the molded part support is in place 22 lowered even further.
  • the shaped jacket 24 is placed on the lower sleeve 23, which is supported by the support ring surface 27.
  • An annular molding space is thus formed by the molding core 14, the lower sleeve (not shown) and the molding jacket 24.
  • This Molding space can then be filled with concrete by means of a concrete dispenser 30, for which purpose the concrete dispenser 30 is moved to the left from its position shown in FIG. 1 until its left end is above the mold core 14.
  • the holders for the crampons 16 carried by a radially inwardly movable wall section 14a of the mold core 14 are moved so far inside the mold core 14 that they release the crampons 16 for a movement of the concrete part then formed upwards.
  • the shaped jacket 24 is moved up again.
  • a lifting platform 32 is used with the molded jacket 24 still raised, while the lower sleeve 23 rests on the support ring surface 27 of the molded core 14 and the molded part support 22 is lowered slightly further than shown in FIG. 1 another power device, namely a hydraulic press 34, is worn.
  • the lifting platform 32 is located within the pit 10 and can be lowered from floor level 12 to the level shown in dashed lines.
  • An operator stands on the lifting platform 32 and grabs as many crampons from an intermediate storage 31 accessible from the lifting platform as he needs for one or more successive loading processes. The operator then moves down and then up again by operating a foot switch 36.
  • the operator During the descent and / or during the ascent, the operator inserts a crampon into the various brackets.
  • the platform can be brought to a standstill at different heights so that the operator can insert the individual crampons when he is in a convenient handling position for the respective holder.
  • the operator After inserting the crampons, the operator is back on the corridor level or - if he has already inserted the crampons during the descent - can return to the corridor level 12 by raising the platform 32 and thus leave the danger area.
  • a seat for the operator can be arranged on the platform 32 and also a support for crampons arranged approximately at the seat height, so that bending down is not necessary.
  • the platform 32 can also be lowered even deeper than shown in broken lines in FIG. 1, so that the lowest crampon positions are easy to reach. If reinforcement rings are to be introduced, it is in principle possible to also insert them from the platform 32.
  • the mold jacket As soon as the crampons and, if necessary, the reinforcement rings are fixed in the mold core 14 and the platform is again at floor level 12, the mold jacket, as described above, is brought into its lowered position by the power device 26 to complete the mold cavity.
  • FIG. 4 shows a modification to FIG. 3.
  • a guide 140 is arranged, which extends between the floor 146, the pit 110 and a covering overhang 148 of this pit.
  • the platform 132 is guided on the guide 140 by means of a slide 132a.
  • the piston rod 134a of the hydraulic press 134 is fixed to the cover projection 148, while the cylinder 134b is connected to the guide carriage 132a.
  • the platform 132 can be pivoted between the operating position shown in solid lines in FIG. 4 and an inoperative position in the direction of the pivot arrow 150. In the inoperative position, the platform 132 takes up little space within the pit 110, so that maintenance work on the mandrel (see FIG. 1) is not hindered.
  • reinforcement parts also includes reinforcement rings, but also, for example, fastening elements which have to be anchored in the concrete part in order to accommodate parts to be subsequently attached to the concrete part.
  • the fact that the platform 32 or 132 can be adjusted in height independently of the molded part support means that crampons which - after insertion - protrude into the mold space, cannot hinder the raising of the platform, because the platform can overlap with the crampons. Accordingly, the operator can, after inserting the crampons, however they are designed, move back up to the corridor before the mold jacket is lowered.
