Definitions

  • the invention relates to a device for standing two rod-shaped Parts, for example a reinforcement in a mold in particular for precast concrete elements with a basic body that has a snap-in holder for Attachment of a reinforcing bar and with at least one Spacer is provided.
  • Precast concrete parts such as ceiling or wall elements are made on large Formwork tables manufactured.
  • the first step on these formwork tables is Reinforcement laid, which must have the precast concrete.
  • This reinforcement must be spaced from the surface of the formwork table, so that concrete poured onto the formwork table flows under the reinforcement can.
  • the one flowing under the reinforcement then forms Concrete which is standard for the corrosion protection of the reinforcement provided coverage.
  • reinforcement meshes are used, for example intended. Such reinforcement meshes are prefabricated in the factory, by welding reinforcement bars in a crossed position become. Reinforcement meshes are relatively expensive and still have the disadvantage that they are in areas of recesses in the precast concrete, such as door or window cutouts interrupted in wall elements need to be cut by punching holes in the mats here become. On the one hand, this is relatively complex and, on the other hand, they are cut mat parts can no longer be used and are therefore undesirable Waste.
  • the crossed reinforcements are usually used instead of Location of longitudinal reinforcing bars and across them trending cross iron manufactured, cut to length become. About cutting can be done without major problems Recesses are provided in the reinforcement.
  • crossing reinforcement and crossbars For this purpose it is known, the crossing reinforcement and crossbars to be welded on-site at their crossing point, but this in particular is relatively expensive because of the expenditure on equipment.
  • the reinforcement and crossbars can be attached to the crossing points are fastened together, but for what again a lot of personnel is required. It is easier there, corresponding To provide spring wire structures that cross the iron on cling to the rebar they cross. The attachment of this Spring wire constructions are also very personnel-intensive because it cannot be automated.
  • the object of the present invention is therefore to provide a corresponding one Spacers, that is, a corresponding device for standing up Reinforcement from reinforcement and cross bars in a mold for precast concrete parts to specify, in which the assembly effort is less, so that lower costs are to be set for this.
  • the advantage of the invention is that the stand device is due to the snap-in receptacle can already be attached to the rebar can before it is placed on the formwork table.
  • this assembly can be carried out mechanically, which means not only manual activities can be saved, but also a more even Distance between two stand-up devices must be ensured.
  • the spacer causing the distance the stand-up device is essentially in the extension of the insertion direction of the cross iron, namely in the downward direction the formwork table.
  • the spacer essentially extends from the main body in the direction from the crossbar and reinforcing bars are insertable. This is especially so useful if the mounting of the stand device is only provided if reinforcing bars and cross bars already cross each other, the spacer then leads past the two irons when the insurgent device is at the intersection of is plugged on top and thus between the formwork table and the then in rebar and crossbar in the raised position.
  • the rebar is used and the cross iron from the same direction into the snap-in receptacle or the locking element inserted and successively independently locked together.
  • spacers can also be attached to a base body Both of the above directions can be provided, so that such Stand-up device can be used more universally.
  • the locking element for Crossbars from two locking arms that extend towards each other in the direction of extension of the cross iron are spaced. This spacing causes the Device in its orientation extending parallel to the transverse iron not because of two mutually spaced attack points can be twisted.
  • These locking arms for the cross iron extend in the preferred embodiment to the side of the area Locking receptacle for the rebar, which makes the locking arms very long run and have greater softness, which allows to fix crossbars of different diameters in the locking element.
  • the base body not only a spacer is provided, with which on the stand a distance to a bottom side is guaranteed, but it is still a further spacer is provided, which is in relation to the first spacer extends in a normal direction. This allows a distance to the boundary walls the concrete form are made possible, so that here too necessary concrete coverage is guaranteed.
  • the said first and second spacers are preferably integral formed in a disc in which the base body in particular is arranged centrally.
  • This disc can advantageously be used in a automatic feeding of spacers as a guide and orientation element use to enable a positionally accurate feeding.
  • a spacer be provided which in turn turns in the normal direction to that of the above Spacers spanned the plane. So that can Stand-up devices on both long and short sides in identical Position are used, which facilitates the automatic assembly.
  • FIG. 6 shows a formwork table 1 for producing a precast concrete part, which is a wall element that one Has door cutout 2 and a window cutout 3.
  • a formwork table 1 for producing a precast concrete part, which is a wall element that one Has door cutout 2 and a window cutout 3.
  • On the formwork table 1 delimited by longitudinal walls 17 and transverse walls 18 is a Reinforcement designed from a variety of parallel to each other Reinforcing iron 4 exists as well as this reinforcing iron cross bars crossing at an angle of 90 ° 5.
  • the reinforcing bars and the crossbars are in the area of the door cutout 2 and the window section 3 cut off, so that no reinforcement in these cutouts runs.
  • the cutouts are by longitudinal racks 19 or transverse racks 20 limited.
  • the formwork table 1 is essentially horizontal (FIG. 6 forms one) Supervision), so that a reinforcement placed on it can be erected must, so that poured concrete on the formwork under the reinforcement can flow to the necessary coverage in the finished concrete part ensure that are normally provided for corrosion protection got to.
  • the reinforcement and crossbars are for this elevation at the locations marked with circles or squares in FIG. 6 provided with stand-up devices.
  • Such a stand-up device is in a side view in FIG. 1 or shown in the front view in Figure 2.
  • the rest area 7 has two detent springs 9 directed into it, on which over the reinforcing iron 8 is pressed into the locking receptacle 7 and which then pulls the reinforcing iron 8 out of the latching receptacle 7 prevent.
  • a spacer extends from this base body 6 10 in the direction in which the reinforcing iron 8 in the locking receptacle is introduced.
  • a spacer 11 is provided, which is extends from the base body 6 in the direction from which the rebar 8 is introduced.
  • one is independent of whether the reinforcement bar 8 is from above is inserted into a stand-up device or whether a stand-up device is pushed over a rebar 8 from above. In both cases is due to the spacer between reinforcing bars 8 and the formwork table 1 a distance necessary for the subsequent covering available.
  • the stand device in addition to the locking receptacle 7 for fastening the reinforcing iron 8 has a further locking element 12, in which a substantially transverse to the reinforcing iron 8 extending cross iron 13 can be snapped.
  • this locking element consists of two Locking arms 14, which - as can be seen in Figure 2 and Figure 5 - are spaced from one another in the direction of extension of the transverse iron 13. This creates both between the left and between the right locking element and the crossbar 13 two independent locking points, so that the stand device in parallel to the cross iron 13 extending orientation can not twist.
  • the stand-up device is parallel to the cross iron 13 Alignment formed as a disc, with also to the side of the locking receptacle 7 or of the one receiving it Base body 6 extend spacers 21 and 22 respectively.
  • the extension is running essentially normal to the vertical extension of the former Spacers 10 or 11.
  • a reinforcing iron 8 is pressed into the snap-in receptacle 7 if necessary, not only with respect to one lying under the spacer 10 Base or base plate spaced apart but also to one side next to the rack parallel to the reinforcing bar 8 transverse wall or crossover. This not only ensures that the concrete is covered properly guaranteed in this direction as well a usual shaking of the formwork table prevents the reinforcing bar 8 strikes against said wall or rack, which causes a lot of noise.
  • the locking arms 15 are opposite the locking arms 14 of Figure 1 significantly extended so that they are larger Have softness. This enables 16 crossbars in the locking element to attach different diameters, since the locking arms 15 the can compensate for different diameters due to their elasticity.
  • a reinforcing bar 8 is shown, on which in a precisely defined Distance mechanically shot upright devices according to Figure 3 were.
  • This rebar is then as in Figure 6 shown placed on a formwork table 1 and then corresponding Cross iron 5 pressed into the corresponding locking elements 16, so that it is then sufficiently firm over the stand device are connected to the reinforcing bars 8.
  • This invention thus has the ability to quickly and inexpensively reinforcement to manufacture for wall elements.
