Definitions
- the invention relates to edge or connection reinforcement for a reinforced concrete component.
- edge baskets or connection baskets for connecting the reinforcements to adjoining other elements are required at the edges of the component.
- Edge cages are formed into U-shaped reinforcement cages, in particular by bending cross bars from lattice-shaped reinforcement mats. To connect the edge cages, they have to be connected to the rest of the reinforcement of the component or to each other on the construction site, which requires a large number of reinforcing steel bars that have to be laid by hand. A reduction in the number of reinforcing steel bars to be bent and braided by hand is desirable for quick, inexpensive and error-reduced laying.
- a method for forming a rigid corner connection for reinforced concrete construction is known from EP 2 175079 B1, in which reinforcement elements, which consist of U-shaped, parallel crossbars and longitudinal bars connecting them, are placed in a corner of a wall or floor section of a reinforced concrete component to be connected be provided that the free ends of the cross bars of a reinforcement element are arranged both in the direction of the soil section to be reinforced and perpendicular to the free ends of cross bars of another, U-shaped reinforcement element, the free ends of which also point in the direction of the soil section to be reinforced.
- This type of edge reinforcement is a simplified reinforcement of angled sections realizable, but it is not applicable for use over the entire length of the side of an edge of a reinforced concrete component.
- the invention is therefore based on the task of proposing edge or connection reinforcement that allows simple edge reinforcement over the entire length of the side of an edge of a reinforced concrete component with prefabricated reinforcement elements, as well as a method for generating such an edge reinforcement.
- edge or connection reinforcement for a reinforced concrete component having at least one first and second reinforcement element, each having U-shaped curved cross bars parallel to one another and longitudinal bars connecting them, with the first and second ends of the longitudinal bars ending freely in overhangs solved that longitudinal bars of a reinforcement element, with parallel arrangement of the bends of the transverse bars of the first and an immediately adjacent second reinforcement element, are offset in position to the longitudinal bars of the other reinforcement element, in particular according to the sequence (AB-) n.
- edge or connection reinforcement Due to the edge or connection reinforcement according to the invention, several corresponding reinforcement elements can be arranged next to one another with great advantage.
- the ends of the longitudinal bars of two directly adjacent reinforcement elements do not abut each other, but rather overlap, which ensures stable reinforcement in the transition area between the two reinforcement elements without additional, manually laid reinforcement bars.
- a variable edge reinforcement is made possible, which, depending on the component or construction site-related requirements, allows the use of any number of edge baskets along an edge of a reinforced concrete component Longitudinal bars within the edge / end reinforcement or the reinforcement cage, different edge reinforcements provided in direct sequence, in particular in the sequence edge reinforcement A- then edge reinforcement B, this in turn connected to a second edge reinforcement A, etc.
- longitudinal bars are arranged within the short sides of the transverse bars and / or that longitudinal bars are arranged within the short sides of the transverse bars and within legs of the transverse bars.
- the reinforcement according to the invention is suitable both for the reinforcement along one side of an edge of a reinforcement element and for the reinforcement of adjacent, angled sides, in which an arrangement of longitudinal bars on the legs of the crossbars would make it difficult for the angled edge reinforcement elements to fit into one another.
- first distances between longitudinal bars within the short sides and second distances within the legs of the transverse bars of a first reinforcement element are the same as the respective corresponding distances between longitudinal bars of a second reinforcement element.
- free ends of all longitudinal bars of the two reinforcement elements form an overlap with protrusions at the free ends of the longitudinal bars of the other reinforcement element, which enables particularly stable reinforcement and makes the reinforcement elements variably replaceable.
- the distance between a plurality of longitudinal irons which are arranged within the short side of the U formed by the transverse irons is equal to the distance between longitudinal irons which are arranged within the legs of the U.
- a reinforcement element has longitudinal bars of different diameters.
- the reinforcement element can be better adapted to the prevailing conditions and the amount of reinforced concrete required is comparatively reduced.
- protrusions of the first and second ends of a longitudinal bar are of different lengths.
- different connection conditions can be implemented at the two ends of the longitudinal bars, for example for arrangement on adjoining walls or further reinforcement elements or on corners of the reinforced concrete component to be reinforced, with the amount of steel required being reduced at the same time.
- a third reinforcement element comprising U-shaped curved cross bars parallel to one another and longitudinal bars connecting these, with the first and second ends of the longitudinal bars ending freely in overhangs, and with the longitudinal bars of the third reinforcing element, with parallel arrangement of the bends of the transverse bars of the first and / or second reinforcement element, offset in position to the longitudinal bars of the respective adjoining third Reinforcement element are arranged.
- the flexibility of the edge reinforcement is increased with great advantage, in particular over edges having long sides.
- first and second reinforcement elements are laid in such a way that free ends of the bend of crossbars of the first and second reinforcement elements are arranged parallel and / or at an angle to one another. This enables the use of prefabricated edge reinforcement elements both along one side of an edge and on angled sections of the edge.
- the first and second reinforcement elements are calculated individually from 3D reinforcement data. This means that the edge reinforcement is integrated into a layout-optimized reinforcement plan and the reinforcement is implemented on the basis of largely prefabricated reinforcement elements.
- Fig. 2 a reinforcement grid as the basis of a reinforcement element according to the invention.
- Fig. 1 shows a first and a second reinforcement element 2, 3 according to the invention - or A, B as above - in cross section. When in use, these are arranged directly next to one another, namely in the sequence ABAB -... or, in other words: (AB) n Cross-section at the level of protrusions 8, 8 'from free ends 6, 7' of longitudinal iron 5, 5 'of the first and the second reinforcement element 3, respectively.
- Both reinforcement elements 2,3 have U-shaped curved transverse bars 4,4 ', which are each connected by longitudinal bars 5,5'.
- the relative position of the longitudinal bars 5 'of the second reinforcement element 3 when the bends 9, 9' of the first and second reinforcement elements 2, 3 are parallel when used, is indicated within the first reinforcement element 2 by means of dashed lines.
- This overlap is achieved when one of the two reinforcement elements is connected directly to the other.
- the length of the overlap depends on the length of the protrusion of the longitudinal bars 5, 5 'of a reinforcement cage relative to its outermost transverse bar.
- the longitudinal bars 5 'of the second reinforcing element 3, which are offset relative to the longitudinal bars 5 of the first reinforcement element 2 can be seen, as well as the overlap formed by the adjacent longitudinal bars 5, 5' along the respective protrusions 8, 8 'of the corresponding free ends 6.7 '.
- the reinforcement elements 2, 3 can be arranged on the same sides or on sides of the edge of the reinforced concrete component 1 that adjoin one another at an angle be.
- longitudinal bars 5, 5 'connecting these longitudinal bars 5, 15' are also arranged along the legs 15, 15 'of the transverse bars (4, 4').
- these longitudinal bars 5,5 ' have a smaller diameter (12) than longitudinal bars 5,5', which are arranged within the short sides 10,10 'of the transverse bars 4,4'.
- a further distance 16 of the longitudinal bar 5 arranged on the leg 15 of the transverse bar 4 of the first reinforcement element 2 to the short side 10 of the transverse bar 4 corresponds, according to the invention, to a corresponding further distance 16 'of the longitudinal bar 5' arranged on the limb 15 'of the second reinforcement element 3 to the short side 10 'of the second reinforcement element 3 plus a diameter 12 of the longitudinal iron 5.
- This arrangement ensures a staggered arrangement of the longitudinal irons 5, 5' adjoining one another when the reinforcement elements 2, 3 are laid in parallel.
- the relative proximity of the two longitudinal irons 5,5 ' creates an overlap of the protrusions 8,8' of the two adjoining ends 6,7 'of the longitudinal irons 5,5'.
- Fig. 2 shows a cross and longitudinal iron 4.5 having reinforcing grid as the basis of a reinforcing element 2 according to the invention.
- the reinforcing element 2 is on the construction site by bending the grid shown along the two dashed lines, on which the bends 9 of the after the bending process U-shaped cross bars 4 are arranged, formed.
- free ends 6, 7 of the longitudinal irons 5 are of different lengths.
- a protrusion 8 is formed, which at a free end 7, a protrusion 8 is formed, which at According to the invention, laying the reinforcement element 2 parallel to a further reinforcement element 3, not shown here, forms the basis of an overlap of adjacent longitudinal bars 5 of both reinforcement elements 2, 3. According to the invention, there is no further arrangement at free ends 6 of the longitudinal irons 5 that do not end in a protrusion 8
- Reinforcement element 3 is provided, but such free ends 6 are provided at corners of the edge of the reinforced concrete component 1 to be reinforced.
- the grid shown has two longitudinal bars 5 within a short side 10 of the transverse bars 4 formed by the bends 9 at a first spacing 11 and two longitudinal bars 5 within a leg 15 of transverse bars 4 at a second spacing 14.
