Definitions

  • the invention relates to reinforcement for reinforced concrete structures, in particular sheet-like structures, with reinforcement elements in the form of a series of U-brackets, which are connected to one another by bars forming longitudinal reinforcement.
  • the invention has for its object to provide a reinforcement of the type mentioned, which, while avoiding these disadvantages, consists of fewer and easier and quick to install reinforcement parts, wherein their elements should also be machine-made and stackable.
  • the support rods should be equally spaced, lie in one plane and encompassed by links having S-hook functions.
  • this object is achieved in that the free legs of the U-bracket have the longitudinal bars receiving or extensive bends, whereby the elements are stackable, and that the reinforcement elements are arranged either individually next to each other or in pairs opposite to each other and offset from one another , whereby transverse to the longitudinal bars of the U-bracket elements serving as transverse reinforcement serving bar coulter elements, single bars or mats are provided.
  • the transverse reinforcement e.g. Bar coulter elements can then be easily and quickly arranged on the outside of the U-bracket elements.
  • the cross reinforcement can also consist of single bars or steel mesh.
  • the U-bracket element 4 consists of U brackets 5 arranged one above the other at a distance Z, for example 50 cm, which have a straight middle part 6, straight legs 7 bent by 90 ° against the middle part 6 and at their free ends have outward bends 8 over an angle of approximately 180 °.
  • the U-brackets 5 are connected to vertical bars 9 arranged transversely to them, e.g. by welding. The arrangement is such that only a pair of rods 9 is covered by the bends 8.
  • a pair of elements 4 is first arranged opposite and offset from one another (FIG. 5), ie an element 4 ′′ (shown in broken lines) is inserted into element 4 ′ in such a way that the rod 9 of element 4 "lies in the middle of the middle parts 6 of the element 4 '. Then the left leg 7 of the element 4 "in FIG. 5 lies approximately in the plane of symmetry of the element 4 'and, conversely, the right leg of the element 4' inevitably lies approximately in the plane of symmetry of the element 4".
  • FIGS. 3 and 4 illustrate how such an element according to FIGS. 3 and 4, which is designated in FIG. 6 with El and is shown with the modification that there is another pair of rods 9 at the junction of the central part 6 with the legs 7, a modular system can be formed over a grid.
  • the distance between the two bars 9 on the central part 6 is 2'X, the distance from the corner bar 9 on the central part 6 to the bar 9 in the subsequent bend 8 being the distance X 1 in the horizontal projection and the distance Y in the vertical projection.
  • the bracket element E2 according to FIG. 7 is obtained; with two further rods 9a and 9b, each in the half and in the quarter point of the middle part 6, to the element E3 according to FIG. 8 and finally with three further rods 9a, 9b and 9c to the element E4 according to FIG. 9.
  • the spacings of the rods 9 on the central part 6 then amount to 3 X in FIG. 7, 4 X in FIG. 8 and 5 X in FIG. 9. In this way, the modular system can be expanded as desired.
  • bracket elements E 1 to E 4 are parts of a modular system that Weils, in the examples shown, the space lying away from the corner bar 9 at the left end of the middle part 6 to the right around the grid unit X, so no additional bar is arranged there; in other words, the distance from that corner bar 9 to the adjacent bar 9a is 2 X each, as can be seen in FIGS. 7 to 9.
  • FIG. 10 An arrangement according to FIG. 10 can also be made.
  • An element E5 is shown in this FIG. 10, in which two rods 9d and 9e, each at a distance X from one another, are arranged on the central part 6, adjacent to the corner rods 9, whereas the space in the middle of the central part 6 remains unoccupied.
  • 11 to 14 illustrate, similar to FIG. 3, the side views corresponding to the elements E1 to E4 according to FIGS. 6 to 9, the brackets 5 again having the distance Z, preferably 50 cm, and end parts of the rods 9 with the Lengths Z1 and Z2 are provided.
  • a change compared to the elements E2 to E4 according to FIGS. 7 to 9 and 12 to 14 for the elements E2.1 to E4.1 according to FIGS. 16 to 18 is that only every second one of the brackets 5 with full length (that is, two legs 7 are formed on the middle part 6 according to FIG. 4);
  • the intermediate bracket 5 ' as shown in Fig. 15, is formed only as a half bracket, consisting of a leg 7' with the bend 8 for the rod 9 at one end and a short straight piece 6 ', which forms a shortened middle part, so to speak.
  • the half-bar 5 ' roughly corresponds to the S-hook according to FIGS. 1 and 2.
  • every third, fourth, etc. bar 5 could be designed with the full length and the intermediate bars as half-bars 5'.
  • the other, known per se, reinforcement element 10 to be combined with the bracket elements according to FIGS. 3 to 18 consists according to FIG. 19 e.g. from a group of horizontal bars 11, which are held by transverse bars 12 spaced apart from one another, preferably welded to them.
  • the required number of pairs of the elements E1 arranged according to FIG. 5 are placed next to one another in succession, etc. such that, as can be seen from FIG. 20, the bars 9 forming the vertical reinforcement come to lie in a grid and at substantially the same distance from one another.
  • the bar coulter elements 10 are then arranged one above the other on the outer sides of the vertical reinforcement thus formed, as is shown schematically in FIG. 20 is shown, and then fixed in the usual way, for example by Rödeln.
  • the reinforcement thus finished, in which the rods 11 and the middle parts 6 are of course each in a common plane, is now ready for concrete within a formwork (not shown in FIG. 20).
  • FIG. 21 A similar representation can be seen in FIG. 21, with the difference that here, along the formwork S, instead of the elements E1 according to FIG. 6, the elements E3.1 according to FIG. 17 are used.
  • the brackets the middle parts of which are at the bottom, are shown in full lines. It can be seen how, according to the design according to FIGS. 6 to 9 (keeping the intersection point adjacent to the corner bar 9 on the central part 6 in the grid), a closed system of bars 9, 9a, 9b of the vertical reinforcement results, taking each crossing point of the grid, with full maintenance of the kink protection in the planes denoted AA by the half-bars 5 '.
  • bracket elements E2 Starting from a first row next to each other, arranged according to the floor plan of the ceiling, similar to element 10 in Fig. 19 trained bar coulter elements E, also consisting of longitudinal bars 11 and cross bars 12, as shown in Figs. 22 and 23, to the Cross bars 12 opposite side of these elements E in pairs arranged bracket elements E2 according to the invention sets and connected to the elements E, as can be seen from the right part of FIG. 25.
  • the corresponding plan view in the arrow direction Pf of FIG. 25 is shown in FIG. 24.
  • a second row of elements E is arranged with its longitudinal bars 11 parallel to that of the first row 25 in the arrow direction Pf of FIG. 25 and attached to the bracket elements E2, whereby the finished ceiling reinforcement is obtained.
  • Another embodiment of the invention consists in lining up elements E1 according to FIG. 6. Since such an element contains all four rods 9 in four adjacent crossing points of the grid, such a juxtaposition at a distance of 2 X to one another is entirely possible (not shown) ).
  • FIGS. 26 to 29 are further configurations according to FIGS. 26 to 29, which are particularly suitable for horizontal reinforced concrete structures such as ceilings, slabs and the like.
  • the element according to Fig. 26 is a U-bracket element 4 intended for the manufacture of such a ceiling, which is composed of side by side at a distance of e.g. 50 cm arranged U-brackets 5, each of which has a straight central part 6, straight, bent by 90 ° against the central part 6 legs 7 and at the free ends of outward bends 8.
  • the U-brackets 5 are interconnected by horizontal bars 9, 9 'arranged transversely to them at right angles, e.g. by welding, a pair of such rods 9 'being in the bends 8 and the other six rods 9 on the outside and in a closed row on the straight central part 6 and at the junctions thereof with the legs 7, that is to say at the corners of the bracket 5.
  • This U-bracket element 4 is assigned a bar coulter element 10 'which has four longitudinal bars 9 "which are held or connected by cross connectors 11.
  • the arrangement is such that these four longitudinal bars 9" lie exactly in the grid, i.e. under the middle four bars 9 on the middle part 6.
  • the middle part of the overall reinforcement is obtained in a simple manner, whereby, as described above, individual bars, bar coulter elements or mats serving as transverse reinforcement are then laid.
  • Fig. 27 shows a similar design as that of FIG. 26, with the difference that the central part 6 here carries eight bars 9 in a closed row, with the bar share element 10 'here correspondingly having six longitudinal bars 9 "in order to form a closed grid .
  • U-bracket elements 4 which are arranged in pairs next to one another and each have four longitudinal bars 9 in a closed row on the straight central part 6.
  • Such a pair of elements 4 is now assigned a bar coulter element 10 ′′, the two middle bars lying in the grid (at x) being omitted, so that it has only a pair of longitudinal bars 9 ′′ on both sides, which in turn lie in the grid.
  • Such a bar coulter element 10 "is arranged symmetrically under the two elements 4, the longitudinal bars 9 'of the elements 4 enclosed by the bends 8 being supported on the cross-connections 11 during this laying.
  • These longitudinal bars 9' now take place in the bends 8 the places which are created on element 10 "at x by omitting the two middle bars, so that here too there is a closed grid.
  • U-bracket elements 4 are provided in pairs, each with five longitudinal bars 9 on the center have part 6, whereas the supplementary bar share elements 10 ", with omission of the two middle bars, each have three longitudinal bars 9" on both sides to form a closed grid.
  • the grid width which is formed by the distance between two legs 7 of adjacent elements 4, e.g. in the order of 15, 20 Vietnamese cm, and the height of the legs 7, with appropriate gradual dimensioning of the steel cross-sectional area of the bars 9, 9 ', 9 ", practically all occurring load cases can be mastered.
