Definitions

  • the invention relates to a reinforcement connection Connection of reinforcement elements of neighboring concrete components, especially in the field of work or Expansion joints consisting of at least one first reinforcement element for the first concrete component and at least a second reinforcement element for the second concrete component, where appropriate, a support element for at least a reinforcement element in the first concrete component is concreted and the reinforcement elements directly or via the support element, if present come into positive engagement by twisting, by at least one reinforcement element has a projection due to the above-mentioned twist on at least one load-bearing surface of the other reinforcement element or if necessary existing support element is clamped.
  • Such reinforcement connections are required to Reinforcement of a concrete component, for example one Ceiling slab, with the reinforcement of an adjoining one To connect component, for example a wall.
  • the problem is that the reinforcement for the second component not through the formwork for the can let the first component pass through.
  • a reinforcement connection similar to that described at the beginning Genus has become known from DE-A 28 29 941. It consists of a support element, which together the reinforcement bars for the first concrete component to the Inside of the formwork for this first concrete component is nailed, using special cover caps it is ensured that the concrete is not to the connecting parts of the support element for the reinforcing bars of the second concrete component. After curing of the first concrete component and the removal of the formwork as well as the mentioned caps are the reinforcement bars for the second concrete component in the connections mentioned of the support element inserted. With these Connecting parts are U-shaped tabs, which have openings on their side walls, in which are the hammerhead-like ends of the reinforcement elements form-fitting for the second concrete component intervention.
  • the task of the present is based on this Invention in that the known reinforcement connection to improve that it stands out for its high load-bearing capacity on the one hand and easy handling on the other distinguished.
  • This training gives you a large area Support between the reinforcement elements, as the Load is transferred over an annular surface.
  • This annular surface is not on circular rings restricted, but can also be an oval or polygonal Have a contour. It is only essential that the previously narrow-edged storage by a extending in the circumferential direction, full-area Storage is replaced.
  • Another advantage is that a high Load transfer not only after a 90 ° turn of the inserted reinforcement element but already with a much smaller pivoting of only for example 40 ° is guaranteed.
  • the lateral insertion is roughly horizontal of the reinforcement element to the swivel axis and thus across the load direction through a slot of the other reinforcement element the advantage that the positive connection between the two parts regardless of the rotational position of the reinforcement elements to each other remains.
  • the reinforcement elements in the state of the art from below in Force direction introduced into the reinforcement connection, and locked only by rotation, which means that if you accidentally swing it back out of the Reinforcement lock can fall out.
  • the bearing surface of the reinforcement elements can be flat but it can also be inclined centering surfaces, act in particular convex or concave surfaces.
  • the storage of the reinforcement element to be used from the outside can be done on the support element; cheaper but is the direct connection to the first reinforcement element, because this means that the supporting element is not worth mentioning Power needs to be transferred and as easier Formwork box can be formed.
  • the support element 1 consists of a Schalkasten, the several by a distance arranged reinforcement connections 2 contains.
  • This Reinforcement connections form the connection between first reinforcing bars 3, which in the embodiment first run up a bit and then under Crossing the support element in the direction of first component to be concreted run on the one hand and second reinforcement bars 4 by the reinforcement connections 2 walking down a bit and then horizontally to the second component to be concreted turn.
  • the latter reinforcement bars 4 are formed as separate elements in the exemplary embodiment, that only after concreting the first component, in Figure 1 that of the one behind the support element 1 Component hung in the reinforcement connections 2 will.
  • reinforcing bars 4 which are detachable are stored in the reinforcement connections
  • reinforcement bars 4 which, however, can then be pivoted about a vertical axis into the Reinforcement connections must be stored so that they in the cavity formed by the spacer 1 can be folded in and nailing the support element do not hinder the formwork.
  • the reinforcing bars 3 are concreted in, so the formwork removed and the reinforcing bars are placed in the drawn active wearing position swung out.
  • Figure 2 illustrates the placement of the reinforcement connections 2 within the support elements 1. You can see there that the bent edges 1a and 1b at their Ends are folded and take up a cover plate 5. This creates the cavity by the reinforcement connections 2 are located reliably against the concrete sealed the first concrete component. This plate 5 after concreting the first concrete component, in 2 shows the component on the left of the support element 1 removed, then the reinforcing bars 4 in the Reinforcement connections 12 hung, whereupon the concreting of the second component on the right of the support element 1 he follows.
  • the reinforcement connector 2 consists of a hollow cylinder, welded to the rebar 3 coming from above is and in its interior a storage room 2a with lower, annular bearing surfaces 2b.
  • the Storage room 2a is of reduced diameter open at the bottom and has a part according to Figure 4 its circumference an opening 2c in the form of a stepped Vertical slot on.
  • the lower reinforcement bar 4 can be inserted laterally. He has a protrusion in shape at its upper end of a projecting covenant 4a, which with play in Cavity 2a of the reinforcement connection fits into it which carries bearing surfaces 4b at its lower end correspond to the bearing surfaces 2b of the reinforcement connection. If the collar 4a sits on the bottom, it will in the transverse direction from the raised edge 2f of the reinforcement connection 2 held.
  • the spring element 6 is as Leaf spring shown on the collar 4a of the reinforcing bar 4 is mounted. Of course it could the spring element instead also part of the Reinforcement connection 2. So that the leaf spring 6 inserting the rebar 4 into the rebar 2 not difficult, it is useful in Orientation of insertion.
  • Figures 3 and 4 show that the Bearing surfaces 2b and 4b are convex and concave, respectively. This has the advantage that you can also create an area Receives attachment to these storage areas if the Reinforcement bar 4 is pivoted slightly to the side. Also then there is full power transmission between the Reinforcement bars 3 and 4 guaranteed.
  • Figure 5 shows a horizontal section through the reinforcement connection 2, but without the bottom reinforcement bar 4 and its covenant 4a. You can see the opening 2c there, which in the lower area only the passage of the reinforcement bar 4 in the upper area but also the passage of the radially projecting collar 4a and is therefore graduated.
  • FIGS. 6 and 7 show a further exemplary embodiment, corresponding parts being the same Have reference numerals.
  • This Embodiment can be easier and cheaper produce as the convex or concave bearing surfaces, which are shown in Figures 3 and 4.
  • the spring element is now a coil spring 6 'trained, the loosely inserted or on upper end of the storage room 2a is attached.
  • the bearing surfaces 2b and 4b are not by a spring element braced against each other, but by one Wedge mechanism.
  • the circumference of the top 4c of the collar 4a is formed. To the others protrude from the top of the cavity 2a corresponding projections 2d down into the cavity inside.
  • the reinforcement element 4 is now by the Slot 2c in the cavity 2a of the reinforcement connection 2 introduced and then twisted against it so that the Wedges 4d and 2d support each other and the floor Press 4b of the collar 4a onto the bottom 2b of the opening.
  • the Reinforcement connection 2 also inside here Storage room 2a with a lower annular storage area 2b, wherein the storage space 2a with a reduced Diameter is open at the bottom and in one part its circumference has a vertical slot 2c. over the lower reinforcement bar 4 can also use this slot its projection 4a inserted horizontally from the side will. It is then initially in the upper one Part of the chamber 2a and can be reached after reaching one Reinforcement connector 2 concentric position down be moved so that its bearing surface 4b on the corresponding bearing surface 2b of the reinforcement connection lies on. Due to the peripheral edge 2f is the projection 4a laterally and can no longer from the Slip out slot 2c.
  • the projection 4a on his Outer cylinder at least one, preferably two vertical Has recesses 4c and that in the reinforcement connection 2 a stop protruding into the storage room 2a 2e is arranged.
  • the stop 2e is positioned in this way and dimensioned that it from the recess 4c are passed when inserting the projection 4a may, however, that he after the projection 4a on the bearing surface 2b with subsequent rotation of the projection with an opposite upper one Front of the projection comes into contact and the Projection 4a more or less braced down.
  • FIGS. 14 and 15 show the upper end face mentioned of the projection designated 4d and wedge-shaped, so that a relatively strong tension is possible is.
  • Arranging two staggered circumferentially Recesses 4c has the advantage that the reinforcement element 4 in two different angular positions in the reinforcement connection 2 can be installed and therefore the subsequent pivoting in one or in the other direction, depending on where you can dodge the iron reinforcement of the ceiling slab got to. Of course it would be the same instead also possible to provide the stop on the support element 1.
  • All of the exemplary embodiments have the advantage in common that the resilience of the reinforcement connection no longer from the angle of rotation of the inserted reinforcement element depends and that angle of rotation and direction of rotation can be varied considerably more than in the known case, so that the reinforcement connection particularly suitable for difficult installation conditions is.
  • the reinforcement connections are in the exemplary embodiments for two horizontally adjacent Concrete components shown. Of course you can the neighboring components but also in completely different Allocation to each other is particularly vertical one above the other or at an angle. As a result, too the reinforcing bars protruding on both sides are completely different To have shape; they should just be in the area the bearing surfaces are approximately axially aligned with one another be positioned.
