Definitions

  • the invention relates to a reinforcing element according to, the preamble of claim 1 and a steel or prestressed concrete component produced therewith according to the preamble of claim 15 or 16.
  • a supported reinforced concrete ceiling is u.a. in the area of the floor supports a shear reinforcement for shear protection necessary.
  • shear reinforcements made of reinforcing steel with reinforcing elements in the form of S-hooks (although no longer permitted in accordance with DIN 1045) or ironing, dowel strips, double head dowels, lattice girders, Tobler Walm, Geilinger collar, ironing mats, crack star and the like.
  • a shear reinforcement with reinforcing elements in the form of S-hooks or straps must enclose a mostly existing Biegel Kunststoffsbewehrung for reasons of poor anchoring to prevent tearing of the shear reinforcement. It should be noted that only a moderate increase in shear force capacity is achieved. The installation of the reinforcing elements is complicated and therefore expensive. In addition, conventional reinforcing elements, such as e.g. Temple, with high reinforcement levels and high shear reinforcement proportion as no longer installable.
  • dowel strips are usually placed on the lower formwork, so that -if existing - the lower reinforcement layer is covered by the strip cross-section For the bearing behavior, however, the exact location and fixation of the bar is rash which is not always guaranteed on the construction site.
  • the dowel strips are welded individual productions which, in relation to the very high costs, produce a barely detectable increase in the lateral force carrying capacity.
  • fasteners or spacers for the upper and lower reinforcement layers are off DE-U1-71 18 881 .
  • DE-OS 2,111,243 or DE-OS-1 913 104 known.
  • these elements do not serve as reinforcing elements, but only to fix the provided in the concrete part reinforcing bars before pouring concrete in a desired position or position. This has no influence on the puncture resistance or even on the load-bearing capacity of the concrete pavement.
  • US 3238684 discloses a reinforcing element according to the preamble of claim 1.
  • the object of the invention is to overcome these and other disadvantages of the prior art and to provide reinforcing elements for installation in steel or prestressed concrete parts, which are simple in construction and inexpensive to produce.
  • the aim is also a good anchorage of the reinforcing elements between the reinforcing bars, the Einabu should be carried out quickly and easily.
  • the reinforcing elements should noticeably increase the stability, in particular the transversal load carrying capacity of the component.
  • the steel or prestressed concrete part should also be inexpensive to produce and easy to handle.
  • the core of the invention forms a reinforcing element according to claim 1 in the form of a planar component, which is located within a concrete part on the surfaces upper and lower reinforcing layers by suitable upper and lower holding means frictionally with each other combines.
  • a reinforcing element according to claim 1 in the form of a planar component, which is located within a concrete part on the surfaces upper and lower reinforcing layers by suitable upper and lower holding means frictionally with each other combines.
  • the reinforcing elements can be manufactured as simple free-falling stampings, which are to be provided with further folds if necessary. This allows extremely cost-effective production, which also has a favorable effect on the production costs for the concrete parts.
  • the reinforcement elements are easy to handle and quick to assemble. They just have to be hung. Special skills or skills, such as those necessary for welding, are not required.
  • the holding means may be designed as bores, as lateral recesses of the sheet-like component and / or as bends, which comprise at least the respective innermost reinforcement layer above and below in the presence of more than one upper and more than one lower reinforcement layer.
  • reinforcing elements of this type if they are installed according to the invention in interaction with the reinforcement layers within a concrete part, in addition to the puncture resistance, especially the lateral force carrying capacity over conventional constructions significantly increase.
  • Fig. 1 This in Fig. 1 generally designated 10 reinforcing element is intended for use in a (not shown here) steel or prestressed concrete component 1. It has as the main part 12 a simple flat body made of structural steel, which has a recess 30 in its upper region 14 and in its lower region 15. The latter is formed by a slot which is open to the lateral longitudinal edge 16 of the flat body 12 and extends approximately from the longitudinal center of M perpendicular thereto.
  • Each recess 30 forms a holding means 20 for a (also not shown here) reinforcing element S, in particular for a reinforcing bar of an upper and lower reinforcing layer Bo, Bu in the steel or prestressed concrete component 1 (see Fig. 26 ). These are each at the (also unspecified component surfaces). They are formed by at least one inner layer Bo_y, Bu_y and at least one outer layer Bo_x, Bu_x running perpendicular thereto.
  • the flat body 12 with its laterally open recesses 30 is simply attached to two directly superimposed, extending in the same direction reinforcing bars S of the inner layers Bo_y, Bu_y, so that each reinforcing bar S is at least partially enclosed.
  • the clear height of the recesses 30 is dimensioned so that the flat body 12 is firmly seated with friction on the reinforcing rods S and can not be solved during the pouring of the concrete.
  • each reinforcing element 10 with its flat body 12 is always transversely, preferably perpendicular to the reinforcing bars S and extends substantially over the thickness of the steel or prestressed concrete component 1, to at least above and below the innermost of at least an inner layer Bo_y, Bu_y of the upper and lower reinforcement layer Bo, Bu. The latter are thereby positively connected with each other.
  • reinforcing elements 10 are e.g. can be manufactured as free-falling stamped parts, which further reduces the production costs. They can be installed quickly and easily at any time, with no special expertise or skills necessary. This also significantly reduces the production costs for the steel or prestressed concrete part 1 to be produced.
  • Fig. 2 has the reinforcing element 10 in its upper portion 14 as a holding means 20, a slot 30, while in the lower region 15, a round or oval recess 30 is provided.
  • Fig. 3 provides as holding means 20 two laterally open slots 30 which extend at an angle a to the longitudinal center M of the flat body 12 obliquely upward.
  • Fig. 4 provides that the slots 30 extend obliquely down at an angle a. In both cases, the placement of the reinforcing elements 10 is facilitated on the reinforcing rods S, especially in confined spaces.
  • a particularly high increase in the transverse load carrying capacity of the steel or prestressed concrete part 1 has to do with the in Fig. 5 shown reinforcing elements 10 result.
  • a total of four holding means 20 are provided in the upper and lower regions 14, 15 of the flat body 12, namely two recesses 30, which are open to the longitudinal edges 16 and are symmetrical to the longitudinal center M.
  • each reinforcing element 10 a total of four rebars S of the upper and lower reinforcing layer Bo, Bu are detected and positively connected with each other, which has a particularly favorable effect on the transverse load capacity of the component 1.
  • each reinforcing element 10 is firmly anchored between the reinforcement layers Bo, Bu. It can not accidentally fall out or slip when pouring concrete. The distances and positions of the reinforcement layers Bo, Bu are always reliably secured.
  • the recesses 30 may each have up and down extensions 32, so that in the region of the longitudinal edges 16 of the reinforcing element 10 locking edges 33 for the reinforcing rods S form.
  • Fig. 6 provides that the extensions 32 of the introduced in the upper region 14 of the flat body 12 recess 30 along the longitudinal center M, while the recess 30 is formed in the lower region 15 is substantially L-shaped, namely with an extension 32 upwards. It can be seen here that the partial area 31 of the recess 30 which is open towards the longitudinal edge 16 has a smaller clearance than the part of the recess 30 located in the longitudinal center M.
  • the recesses 30 can be provided with a securing means 34.
  • a securing means 34 is, for example, a substantially U-shaped clamping element made of an elastic material, which can be reduced by pressure on its two outer legs in width and thus introduced into the recess 30 (see Fig. 7 ). If you let go of the legs, they lie from the inside against the walls of the slot 30 in the flat body 12, so that a lying in the recess 30 rebar S can not laterally slip out.
  • the securing elements 34 are formed by bolts, which are inserted into frontally inserted into the flat body 12 or laterally mounted receptacles 35.
  • the attachment of preferably color conspicuously designed display means 36 so that the introduction of a bolt 34 can be easily marked and recognized on the site.
  • a bolt 34 or other locking means rotatable, and a stop pin may be arranged, wherein the bolt 34 is rotated after insertion of a reinforcing element S between the reinforcing element 10 and the stop pin.
  • On the bolt 34 attached display means 36 would then all point in one direction or have the same inclination or position relative to the reinforcing element 10 and thereby indicate the secure state even for a large number of reinforcing elements 10 quickly verifiable.
  • Fig. 9 shows further advantageous embodiments of securing means 34, for example in the form of a simple elastic element, for example a strip or in the form of a simple wedge.
  • FIG Fig. 10 Another important embodiment of the reinforcing element 10 is shown in FIG Fig. 10 shown.
  • the holding means 20 is formed in the upper region 14 of the sheet-like body by a simple folded edge 40 formed on the end side. This preferably encloses a reinforcing bar S of the outer layer Bo_x the upper reinforcement layer Bo (see Fig. 26 , left element 10).
  • the holding means 20 in the lower region 15 of the planar body 12 is an L-shaped recess 30 which encloses a reinforcing bar S of the inner layer Bu_y of the lower reinforcement layer Bu.
  • FIG. 11 to 13 show the holding means 20 in the form of recesses 30 and folds 40 almost arbitrarily combine with each other, wherein reinforcing rods S of the inner and outer layers Bo_y, Bu_y, Bo_x, Bu_x can also be detected simultaneously.
  • Fig. 11a the bent portion 40 formed in the upper region 14 is angled backwards, while the fold 40 in the lower region 15 points forwards.
  • the reinforcing element 10 thus has - as in Fig. 11b to recognize - in cross-section a substantially Z-shaped configuration, while the embodiment of Fig. 12, 12a in cross-section provides a U-profile.
  • Fig. 13a, 13b can the bends 40 also be formed twice or more times, where - like Fig. 15b by way of example - for the reinforcing element 10 in cross section can give an S-shape.
  • Fig. 16 based on the design of Fig. 6 , ie in the upper and lower regions 14, 15 of the flat body 12, a total of four recesses 30 are provided as holding means 20 symmetrically to its longitudinal center M, which surround the reinforcing rods S form fit.
  • the recesses 30 are not open to the longitudinal edges 16, that is, the reinforcing rods S are introduced substantially perpendicular to the flat body 12.
  • Additional folds 40 surround as additional holding means 20, the respective outer layer Bo_x, Bu_x the upper and lower reinforcement layer Bo, Bu, so that the reinforcing elements 10 are optimally integrated into the steel or prestressed concrete part 1 to increase the shear capacity.
  • its ductility increases with transverse force stress.
  • the flat body 12 is formed profiled in cross section, wherein the profiling 24 formed by simple, preferably rectangular bends between the upper and lower reinforcing layer (Bo, Bu) is formed.
  • the reinforcing elements 10 can also enclose more than four reinforcing rods S.
  • the planar body 12 is to be lengthened transversely to its longitudinal center M and provided with the required number of holding means 20.
  • two reinforcing elements 10 are arranged in the longitudinal direction of at least one reinforcing bar (S) V-shaped side by side, wherein the flat body 12 are connected to each other in their upper regions 14 or in one piece.
  • Fig. 19 provides that several reinforcing elements 10 are parallel behind each other.
  • Each flat body 12 is in this case connected with its upper portion 14 T-shaped with a flat iron 26, which over the width of the reinforcing elements 10th protrudes to at least partially hold or embrace an element S of the upper reinforcement layer Bo.
  • Fig. 20 form the reinforcing elements 10 and the flat iron 26 a U-profile, the latter also serves as a holding means 20 by enclosing at least one reinforcing bar S of the upper reinforcement layer Bo.
  • FIG. 21 shows - also perform rectangular and two parallel juxtaposed reinforcing elements 10 by means of a resilient clamp 28 with each other, the bracket 28 is fixed with their (unspecified) legs in the recesses 30 while also enclosing at least one reinforcing bar S of the upper reinforcement layer Bo ,
  • FIGS. 22 to 24 Yet another important embodiment results from the FIGS. 22 to 24 Namely, when the planar body 12 of the reinforcing element 10 is divided perpendicular to its longitudinal center M in a lower half 50 and an upper half 60, wherein both halves 50, 60 are releasably connectable to each other.
  • the thickness of the concrete floor can be designed individually by using different lengths of upper halves 60 of the reinforcing elements 10. These can be provided in their end regions 14, 15 with different holding means 20, in particular also bends 40.
  • the halves 50, 60 are preferably connected by hook-shaped connecting elements 52, 62, which mesh with one another in a positive and / or positive manner. It is important that an always strong connection is created.
