Definitions
- the invention relates to a reinforcement element according to the preamble of claim 1 and to a steel or prestressed concrete part produced therewith according to the preamble of claim 30.
- a supported reinforced concrete ceiling is i.a. In the area of the floor props, shear reinforcement is necessary to secure shear.
- shear reinforcement made of reinforcing steel with reinforcement elements in the form of S-hooks (although no longer permitted according to DIN 1045) or stirrups, dowel strips, double-headed dowels, lattice girders, Tobler Walm, Geilinger collars, ironing mats, crack star and the like.
- a shear reinforcement with reinforcement elements in the form of S-hooks or stirrups must enclose a mostly existing longitudinal reinforcement in order to prevent the shear reinforcement from being torn out due to poor anchoring. It should be noted that only a moderate increase in the shear strength is achieved. The installation of the reinforcement elements is complex and therefore expensive. In addition, conventional reinforcement elements apply, e.g. Stirrups, can no longer be installed with high degrees of reinforcement and high shear reinforcement.
- dowel strips are usually placed on the lower formwork, so that - if available - the lower reinforcement layer is covered by the strip cross-section. For the load-bearing behavior, however, the exact position and fixation of the bar is crucial bend, which cannot always be guaranteed on the construction site.
- the dowel strips are also welded, one-off products which, in relation to the very high costs, cause an almost undetectable increase in the shear strength.
- Connecting elements or spacers for the upper and lower reinforcement layers are known for example from DE-U1-71 18 881, DE-U 1-298 14 923, DE-OS-2 111 243 or DE-OS-1 913 104.
- these elements do not serve as reinforcement elements, but only to fix the reinforcement bars provided in the concrete part in a desired position or position before they are poured with concrete. This has no influence on the punching strength or even on the shear load capacity of the concrete floor.
- the object of the invention is to overcome these and other disadvantages of the prior art and to provide reinforcement elements for installation in steel or prestressed concrete sections, which are simple in construction and can be produced cost-effectively.
- the aim is also to anchor the reinforcement elements well between the reinforcement bars, and the installation should be quick and uncomplicated.
- the reinforcement elements should noticeably increase the stability, especially the shear load carrying capacity of the component.
- the steel or prestressed concrete part should also be inexpensive to manufacture and easy to handle.
- the core of the invention is a reinforcement element in the form of a flat component, which non-positively connects the upper and lower reinforcement layers located on the surfaces within a concrete part by means of suitable upper and lower holding means. connects each other. This significantly increases the shear load capacity of the steel or prestressed concrete part.
- the reinforcement elements can be manufactured as simple free-falling stamped parts, which may have to be provided with further bends. This enables extremely cost-effective production, which also has a favorable effect on the manufacturing costs for the concrete parts.
- the reinforcement elements are easy to use and quick to assemble. They just have to be hung up. Special expertise or skills, such as those required for welding work, for example, are not required.
- the holding means can be designed as bores, as lateral recesses from the flat component or / and as bevels which, in the presence of more than one upper and more than one lower reinforcement layer, comprise at least the innermost reinforcement layer at the top and bottom.
- reinforcement 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 punching shear strength, above all significantly increase the shear force resistance compared to conventional constructions.

- 26 is a schematic representation of a steel or prestressed concrete part
- the reinforcement element is intended for use in a steel or prestressed concrete part 1 (not shown in more detail here).
- main part 12 it has a simple flat body made of structural steel, each of which has a recess 30 in its upper region 14 and in its lower region 15. The latter is formed by an elongated hole which is open towards the lateral longitudinal edge 16 of the flat body 12 and extends approximately perpendicularly to it from its longitudinal center M.
- Each recess 30 forms a holding means 20 for a reinforcement element S (also not shown here), in particular for a reinforcement bar of an upper and lower reinforcement layer Bo, Bu in the steel or prestressed concrete part 1 (see FIG. 26). These are each on 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 to it.
- the flat body 12 with its laterally open recesses 30 is simply plugged onto two reinforcement bars S of the inner layers Bo_y, Bu_y which lie directly one above the other and run in the same direction, so that each reinforcement bar S is at least partially enclosed.
- the clear height of the recesses 30 is dimensioned such that the flat body 12 sits firmly on the reinforcing bars S with frictional engagement and cannot come loose during the pouring of the concrete.
- each reinforcement element 10 with its flat body 12 is always transverse, preferably perpendicular to the reinforcing bars S and extends essentially over the thickness of the steel or prestressed concrete part 1, to at least above and below the innermost of the at least an inner layer Bo_y, Bu_y of the upper and lower reinforcement layer Bo, Bu. The latter are thereby positively connected to one another.
- reinforcement elements 10 Another advantage of the reinforcement elements 10 is that, thanks to their simple geometry, they can e.g. can be manufactured as free-falling stamped parts, which further reduces manufacturing costs. They can be installed quickly and easily at any time, with no special knowledge or skills required. This also significantly reduces the manufacturing costs for the steel or prestressed concrete part 1 to be manufactured.
- the reinforcement element 10 has an elongated hole 30 in its upper region 14 as holding means 20, while a round or oval recess 30 is provided in the lower region 15.
- the embodiment of FIG. 3 provides two laterally open slots 30 as holding means 20, which run obliquely upwards at an angle a to the longitudinal center M of the flat body 12.
- the design of FIG. 4 provides that the elongated holes 30 run obliquely downward at an angle a. In both cases, the placement of the reinforcement elements 10 on the reinforcing bars S is facilitated, particularly in the case of limited space.
- a particularly high increase in the transverse load-bearing capacity of the steel or prestressed concrete part 1 has been achieved with the reinforcement elements 10 shown in FIG. 5.
- 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 towards the longitudinal edges 16 and are symmetrical to the longitudinal center M.
- a total of four reinforcement bars S of the upper and lower reinforcement layers Bo, Bu are thus detected from each reinforcement element 10 and non-positively connected to one another, which has a particularly favorable effect on the shear load carrying capacity of component 1.
- each reinforcement element 10 is firmly anchored between the reinforcement layers Bo, Bu. It cannot fall out accidentally or slip when pouring concrete. The distances and positions of the reinforcement layers Bo, Bu are always reliably secured.
- the recesses 30 can have upward and downward extensions 32, so that there are 10 locking edges 33 for the reinforcing rods S in the region of the longitudinal edges 16 of the reinforcing element form.
- FIG. 6 provides that the extensions 32 of the recess 30 made in the upper region 14 of the flat body 12 lie along the longitudinal center M, while the recess 30 in the lower region 15 is essentially L-shaped, namely with an extension 32 up. It can be seen here that the partial region 31 of the recess 30 which is open towards the longitudinal edge 16 has a smaller clear height 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 This is, for example, an essentially U-shaped clamping element made of an elastic material. rial, which can be reduced in width by pressure on its two outer legs and thus inserted into the recess 30 (see FIG. 7). If you let go of the legs, they lie from the inside against the walls of the elongated hole 30 in the flat body 12, so that a reinforcing bar S lying in the recess 30 can no longer slide out laterally.
- the securing elements 34 are formed by bolts which are inserted into receptacles 35 which are introduced into the flat body 12 on the end face or laterally attached. It is advantageous to attach display means 36, which are preferably of a striking color, so that the insertion of a bolt 34 on the construction site can be easily marked and recognized.
- a bolt 34 or another locking means can also be rotated on the longitudinal edge 16 of the flat body 12, and a stop pin can be arranged, the bolt 34 being rotated between the reinforcement element 10 and the stop pin after the introduction of a reinforcement element S.
- Display means 36 attached to the bolt 34 would then all point in one direction or have the same inclination or position relative to the reinforcement element 10 and thereby quickly display the secured state for a large number of reinforcement elements 10.
- Fig. 9 shows further advantageous embodiments for securing means 34, for example in the form of a simple elastic element, e.g. a strip or in the form of a simple wedge.
- the holding means 20 is formed in the upper region 14 of the flat body by a simple bevel 40 formed on the end. This preferably encloses a reinforcement bar S of the outer layer Bo_x of the upper reinforcement layer Bo (see FIG. 26, left element 10).
- the holding means 20 in the lower region 15 of the flat body 12 is an L-shaped recess 30, which includes a reinforcing bar S of the inner layer Bu_y of the lower reinforcing layer Bu.
- the holding means 20 in the form of recesses 30 and bevels 40 can be combined with one another almost as desired, reinforcing bars S of the inner or outer layers Bo_y, Bu_y, Bo_x, Bu_x can also be detected simultaneously ,
- the fold 40 formed in the upper region 14 is angled backwards, while the fold 40 points forward in the lower region 15.
- the reinforcement element 10 thus has - as can be seen in FIG. 11b - an essentially Z-shaped shape in cross section, while the embodiment of FIGS. 12, 12a provides a U profile in cross section.
- the bevels 40 can also be designed twice or more, whereby — as shown by way of example in FIG. 15b — an S shape can result for the reinforcement element 10 in cross section.
- Fig. 16 is based on the design of Fig. 6, i.e. In the upper and lower region 14, 15 of the flat body 12, a total of four recesses 30 are provided symmetrically to its longitudinal center M as holding means 20, which enclose the reinforcing bars S in a form-fitting manner.
- the recesses 30 are not open to the longitudinal edges 16, i.e. the reinforcing bars S are inserted essentially vertically into the flat body 12.
- Additional bevels 40 enclose the additional outer layer Bo_x, Bu_x of the upper and lower reinforcement layer Bo, Bu as additional holding means 20, so that the reinforcement elements 10 are optimally integrated into the steel or prestressed concrete part 1 in order to increase the transverse load carrying capacity.
- its ductility increases when subjected to shear forces.
- the flat body 12 is profiled in cross section, the profiling 24 formed by simple, preferably right-angled bevels being formed between the upper and lower reinforcement layers (Bo, Bu).
- the reinforcement elements 10 can also enclose more than four reinforcement bars S.
- the flat body 12 is to be extended transversely to its longitudinal center M and provided with the required number of holding means 20.
- two reinforcement elements 10 are arranged in a V-shape next to one another in the longitudinal direction of at least one reinforcement bar (S), the flat bodies 12 being connected to one another or in one piece in their upper regions 14.
- Each flat body 12 is connected with its upper region 14 in a T-shape to a flat iron 26 which extends over the width of the reinforcement elements 10 protrudes to at least partially hold or encompass an element S of the upper reinforcement layer Bo.
- the reinforcement elements 10 and the flat iron 26 form a U-profile, the latter also serving as holding means 20 by enclosing at least one reinforcement bar S of the upper reinforcement layer Bo.
- the recesses 30 in the upper region 14 of the flat body 12 - as shown in FIG. 21 - can also be made rectangular and two reinforcement elements 10 arranged in parallel next to one another can be connected to one another by means of a spring-elastic clamp 28, the clamp 28 with its (unspecified) Legs is set in the recesses 30 and also encloses at least one reinforcing bar S of the upper reinforcement layer Bo.
- FIGS. 22 to 24 Another important embodiment of the invention results from FIGS. 22 to 24, namely when the flat body 12 of the reinforcement element 10 is divided perpendicularly to its longitudinal center M into a lower half 50 and an upper half 60, both halves 50, 60 are releasably connectable.
- the thickness of the concrete ceiling can be individually designed by using different lengths of the upper halves 60 of the reinforcement elements 10. In their end regions 14, 15, these can be provided with various holding means 20, in particular also bevels 40.
- the halves 50, 60 are preferably connected by hook-shaped connecting elements 52, 62, which interlock with one another in a non-positive and positive manner. It is important that there is always a tension-resistant connection.
- the lower half 50 of the reinforcement element 10 is supplemented by an upper half 60 made of a round steel 66, which is bent in a Z-shape and can engage in a corresponding recess in the lower half 50.
- FIG. 25 shows two views of the broad side of a further embodiment of the reinforcement element 10 according to the invention.
- This embodiment is distinguished in that the area between the dashed lines with respect to the areas above or below it forwards or backwards from the image plane or inwards is offset against the upper and lower area. This becomes visible when looking at the narrow edge of the two components.
- the component 10 can also be designed such that e.g. only an upper part is offset against a lower part of the component, e.g. is formed by edging or pressing.
- the reinforcement element 10 in the middle of FIG. 26 each comprises an element S of the outer layer Bo_x, Bu_x of the upper and lower reinforcement layers Bo, Bu, while the reinforcement element 10 shown on the right in FIG. 26 only connects elements S of the inner layers Bo_y, Bu_y of the upper and lower reinforcement layers Bo, Bu.
- component 1 has a significantly increased shear load capacity.
- the reinforcement elements 10 can also be made of other materials such as sheet steel, plastic, or composite Material. You can also form the reinforcement elements 10 or their flat bodies 12 extended transversely to the longitudinal center M in order to enclose several reinforcement bars S of the upper and lower reinforcement layers Bo, Bu at the same time.
- the reinforcement elements 10 are always simple flat sheet metal parts which may or may not be canted at the ends or in the middle and which have holding means in the upper and lower region for receiving or for enclosing the reinforcing bars S of an upper and lower reinforcement layer Bo, Bu , Installation takes place without complex welding or assembly work, the upper and lower reinforcement layers Bo, Bu being connected to one another by the reinforcement elements 10 in the pulling direction.
