Definitions

  • the invention relates to a device for reinforcing reinforced concrete or Prestressed concrete structures, in particular for reinforcement on columns superimposed flat ceilings against punching, with preferably as Anchor bolts designed reinforcement elements, which by means of at least a carrier arrangement preferably arranged on the head side in groups are interconnected.
  • a device of this type is known from EP 0495 334 B1.
  • the anchor bolts with the associated Beam assembly welded. Because of this tight connection between the anchor bolt and the bracket assembly, it is not possible to position it to vary the anchor bolt along the support arrangement and accordingly the mutual distances between the anchor bolts change. This can lead to difficulties on the construction site.
  • the anchor bolt usually in assigned grid fields of a grid structure Bending reinforcement must be introduced. Depending on whether the longitudinal axis the beam arrangement with respect to the grid reinforcement diagonally or runs axially, there are different grid spacings. It exists hence the risk that the anchor bolts collide with bars.
  • FIG. 1 shows a reinforcement unit 1 of a punching shear reinforcement. This contains a group of several, arranged in a row one behind the other Reinforcement elements 2. These are for the purpose of securing the position a continuous support arrangement over the length of the reinforcement unit 1 3 added. For creating longer reinforcement arrangements can, as can be seen from FIG. 3, a plurality of reinforcement units 1 can be connected to each other.
  • the reinforcement elements 2 are here made of structural steel, with in Area of their ends, plate-shaped heads 4 provided, massive anchor bolts formed which are arranged with a standing axis and with their upper ends on the associated carrier arrangement 3 are suspended, so when installing on an assigned bending reinforcement be put on.
  • the carrier arrangement 3 is here as a ladder-shaped Welded construction with two parallel longitudinal bars 5 and these connecting cross bars 6 formed.
  • a built carrier arrangement here, of course, could also be one Preformed rail of the type used in FIGS. 4 and 5 Find.
  • the longitudinal and transverse spars 5,6 are shown Example from round bar material. Of course, others could too Cross-sectional shapes, such as angles, etc. may be provided.
  • the position of the reinforcement elements 2 in the longitudinal direction of the support arrangement 3 to be able to vary, in particular to the mutual distances to be able to vary the reinforcement elements 2 are Reinforcement elements 2 by detachable, in the released state fastening means which can be displaced in the longitudinal direction relative to the carrier arrangement 3 7 connectable to the carrier arrangement 3.
  • the fasteners 7 as clamping members formed between the parallel longitudinal bars 5 of the support arrangement 3 can be snapped into place.
  • the fasteners designated as a whole with 7 exist here, as on can best be seen from FIG. 2, in each case from two sleeve-shaped, nested housing parts 8, 9, which by means of a between them inserted compression spring 10 with its ends on each other facing bottoms of the two sleeve-shaped housing parts 8.9 is supported, are telescopic.
  • the one from the other opposite ends of the two housing parts 8,9 practically form the compression spring 10 expandable clamping jaws, which by clamping action, So non-positively, on the longitudinal spars 5 against shifting in Longitudinal beam direction can be determined.
  • the housing parts 8, 9 which can be moved apart by means of the compression spring 10 are initially blocked when pushed together.
  • An in FIG. 2, split pin 11 indicated by broken lines Find the use of through-aligned through recesses the housing parts 8.9 can be pushed through.
  • the two sleeve-shaped Housing parts 8.9 can engage in each other so far that the distance between their ends facing away from each other is smaller than the clear one Distance of the longitudinal spars 5 of the support assembly 3 is, so that the Fasteners can be inserted between the longitudinal bars 5.
  • the two housing parts 8, 9 are opposed the spreading force of the compression spring 8 by means of a clamping tool 12 held. As can be seen in FIG.
  • this can be designed as a pair of pliers tips insertable into assigned recesses in the housing parts 8, 9 is provided.
  • the two housing parts 8, 9 are the best FIG. 3 can be seen, with bores 13 spaced apart from one another Mistake.
  • the outer one, which acts as the cylinder of the telescope assembly Housing part 8 also has a bore 13 of the inner, as a piston the elongated hole assigned to the telescopic arrangement of the housing part 9 14, through which the mutual achievable by means of the clamping tool 12 Movement of the housing parts 8.9 is limited.
  • the fastener 7 forming telescope assemblies gently in Bring system to the longitudinal bars 5 of the support assembly 3, whereby fixation by clamping action.
  • the carrier arrangements 3 arranged one behind the other are, as from FIG 3 can be seen, arranged so that the closed 15 formed by the sheet End of a support assembly 3 in the through the V-shaped opposed rod ends 16 formed open ends of the engages another carrier arrangement 3.
  • they are arranged one behind the other Reinforcement units 1 arranged practically coplanar. But it would be too an angled arrangement is easily conceivable. The limit will formed by the spreading angle of the rod ends 16.
  • FIGS. 4 and 5 formation takes place a carrier arrangement 3a, as already mentioned above, a profiled rail section Use.
  • the example shown is a rolled, C-shaped steel rail in cross section. This lies with its web 18 on the heads 4 of the associated reinforcement elements 2, which the Reinforcement elements according to Figures 1 to 3 correspond.
  • the web 18 is as can best be seen from FIG. 5, by side flanges 19 flanked, so that there is an upwardly open channel.
  • the flanges 19 can follow at their upper ends to form a narrow window be angled inside.
  • the web 18 is, as shown in Figure 4, in the form of a Row arranged through recesses 20 provided. It can are a row of holes.
  • fastening screws 7a are provided here. This are, as can be seen from Figure 5, with their head 21 on the web 18 and can with their through a through hole 20 Threaded shaft 22 in an associated threaded hole of the reinforcement element to be held 2 can be screwed in.
  • Threaded shaft 22 in an associated threaded hole of the reinforcement element to be held 2 can be screwed in.
  • the reinforcement elements 2 can the screws mentioned in the case of a row of holes be implemented from hole to hole. In the case of a row of slots the screws in the loosened state within the slot length be moved. If this is not sufficient, one can also Conversion from slot to slot is done.
  • FIG. 6 shows an example of a shear reinforcement arrangement, such as for bridging the butt joint can be used between two adjacent plates.
  • the provided for receiving the reinforcement elements 25 support arrangement 26 can be one of the carrier arrangement according to FIGS. 1 to 3 Have structure.
  • the reinforcement elements 25 run transversely to this the longitudinal spars 27 of the ladder-shaped carrier arrangement 26.
  • the reinforcement elements 25 are also here in the longitudinal direction Carrier assembly 26 is displaceable.
  • fastening means 28 are on the carrier arrangement 26 provided that allow such a change in position.
  • the Fastening means 28 are designed here as double clamps. Own them in each case a two-armed spring clamp which can be latched onto a longitudinal beam 27 29 and a lockable on the associated reinforcement element 25, two-armed spring clamp 30.
  • the two spring clamps 29, 30 are in shown example rotated by 90 ° to each other.
  • Each Reinforcement element 25 are assigned two fastening means 28 here snapped onto the two longitudinal spars 27 of the carrier arrangement 26 will.
  • the reinforcement element 25 is connected to the associated spring clips 30 also just snapped into place. It is therefore through towards it Movable axis.
  • the present double terminal training of Fasteners accordingly allow the reinforcement elements to be moved 25 not only in the longitudinal direction of the carrier arrangement 26, but also transversely to it in the direction of the axis of the reinforcement elements 25th
  • carrier arrangement 3 or 26 does not allow only a separate production of the individual parts, but also one separate transport and storage.
  • the assembly can done on site. But it is also possible to have one at the factory To carry out pre-assembly, so that only the position on the construction site the reinforcement elements 2 and 25 must be corrected. To do this simply loosened or disengaged the fasteners and slips.
