Definitions

  • the invention relates to a reinforcing steel strip for sheet-like Reinforced concrete structures consisting of several to each other parallel, with mutual spacing in one plane arranged reinforcing bars and several perpendicular to the reinforcing bars trending, weaker than this trained and with these welded positioning wires.
  • AT-PS 346 046 is a reinforcement for crosswise reinforced ceiling tiles with at least two separate, known among combinable partial reinforcement elements, each of which is a bevy of parallel to one direction and has rigidly combined rods. Hiebei the partial reinforcement elements are placed crosswise on top of each other, so that they have a surface reinforcement with crossing reinforcing bars any dimension and any steel cross-section form.
  • the partial reinforcement elements consist of several equally long reinforcement bars, which are supported by two holding bars can be summarized rigid.
  • the partial reinforcement elements are based on a grid with a constant module constructed, the distances between the reinforcing bars the module, the length of the partial reinforcement element is a multiple of the module and the length of the support rods and thus the width of the Partial reinforcement element preferably a multiple of the module correspond.
  • the distance of the support rods from the ends of the Reinforcing bars must be at least twice the adhesive length of the reinforcing bar increased by the module.
  • To the elements in To be able to summarize modular form, must also Steel cross section of the reinforcement bars according to the length dimension be graded in a certain way.
  • the Partial reinforcement element has the disadvantage that its construction in one predetermined grid size must be done and its manufacture is therefore very complicated and expensive. Besides, one is Large variety of types required to solve reinforcement tasks and a quick and flexible adaptation to on site Laying plans to be changed are not possible.
  • AT-PS 275 111 is a reinforcement unit for reinforcement known from area strips, the width of 0.2 to 0.7 m is and the at least three and at most four longitudinal wires has, which by several, the dimensional stability of the reinforcement unit guaranteeing, transverse and weaker trained cross wires are connected.
  • This reinforcement unit has the disadvantage that the number of longitudinal wires is limited and therefore only relatively narrow reinforcement strips can be produced are. In addition, neither to the arrangement of the cross wires nor details on the dimensions of the reinforcing bars.
  • the object of the invention is to provide a universally applicable to create a simple reinforcing steel strip that allows with only a small number of series-producible ones Basic types of reinforcing steel strips a stock program too create and easily and with little effort the reinforcement of sheet-like reinforced concrete structures the disadvantages of rebar reinforcement, of reinforcement meshes designed as storage and list meshes as well as the known strip-shaped reinforcement elements should be avoided.
  • the reinforcing steel strip for the formation of standard reinforcement elements of a stock program a width of at least 1000 and at most 1200 mm and a length in the range of 4 to 9 m and has a maximum of seven at a distance of 200 mm reinforcing bars arranged with each other with ribbed Surface and with a diameter in the range of 6 to 16 mm as well as several, at a distance of 400 to 1200 mm mutually arranged position wires is formed, wherein which are adjacent to the free ends of the reinforcing bars Position wires a distance of from the rebar ends 200 to 500 mm.
  • the reinforcement bars consist of hot-rolled or alternatively from cold-formed reinforcing steel.
  • the position wires preferably close with the Reinforcement bars flush.
  • the invention ensures that the reinforcing steel strips with minimal cutting effort almost lossless to the Dimensions of the reinforced concrete components to be reinforced can.
  • the reinforcing steel strips are sufficiently stiff and easy to manipulate. Due to the width from 1000 to 1200 mm less storage space is required for the reinforcing steel strip. As a result of the specified projections of the reinforcing bars is inserting the reinforcing steel strips on the Support in reinforcements or the like. easily possible and must the positioning wires at the reinforcing steel strip ends when laying not be separated.
  • Standard reinforcement elements of a stock program are formed, whereby for a diameter of the reinforcing bars only one Basic type of reinforcing steel strips in various lengths as standard is produced. In an optimal way, therefore Solve all reinforcement tasks with the help of the reinforcing steel strips, see above that the previously required variety of strip-shaped reinforcement elements, Storage or list mats by just a few Basic types of reinforcing steel strips according to the invention replaced can be.
  • the Reinforcing steel strips according to the invention like a wide reinforcement bar be treated.
  • the reinforcing steel strip can be used for reinforcement elements, bearing or list mats produced particularly easily and economically be because already during the production of the hot-rolled Reinforcing bars directly after the cooling bed of the Rolling mill the individual reinforcement bars to a multiple length cut the end length of the reinforcing steel strip and bundle them same length can be summarized.
  • the conventional one Storage mats require time-consuming and complex cutting work store at the laying point or at the sales point not applicable.
  • the reinforcement bars are used to manufacture the reinforcing steel strips with the help of standard mesh welding machines welded to the positioning wires. With a width of the reinforcing steel strip the standard production width of 1.2 m of these mesh welding machines optimally exploited and two lanes simultaneously in one welding machine of reinforcing steel strips produced particularly economically become.
  • the width of 1.2 m of the reinforcing steel strip continues the advantage that the standard truck bed of 2.4 m optimally used when transporting the reinforcing steel strips can be.
  • the invention has Reinforcing steel strips the advantage that it depends on weight and Length of one worker or at most two workers manipulated and can also be transported upright.
  • a Another advantage over list mats is that in simple way with a cross to be reinforced Reinforced concrete construction reinforcement in both directions can be chosen differently.
  • the reinforcing steel strip according to the invention has the advantage that when laying there are no overlaps and therefore none Steel accumulations and no loss of static height Multiple layers in the joint area arise.
  • the reinforcing steel strip 1 shown in FIGS. 1 and 2 consists of seven parallel to each other, with a mutual Reinforcement bars spaced 200 mm apart on one level 2, through several transverse positioning wires 3, 3 'are interconnected.
  • the reinforcing steel strip 1 has one Width of 1200 mm.
  • the number the reinforcing bars 2 are also six, so that reinforcing steel strips can be manufactured with a width of 1000 mm.
  • the diameter of the reinforcing bars 2 are corresponding the static requirements for the reinforcing steel strip 1 in Range from 6 to 16 mm.
  • the diameter is graded here the reinforcement bars 2 in the range of 6 to 10 mm in 1 mm increments and in the range of 10 to 16 mm in increments of 2 mm.
  • the surface of the reinforcing bars 2 is with ribs provided to the adhesion of the reinforcing bars 2 in the concrete too increase.
  • the reinforcement bars 2 are either hot-rolled or cold-formed, drawn or rolled reinforcing steel with mechanical strength values accordingly the static requirements for the reinforcing steel strip 1.
  • the reinforcing steel strip 1 has a length in the range of 4 to 9 m, the length gradation in the range of 4 to 7 m in Steps of 500 mm and in the range of 7 to 9 m in steps of 1000 mm. With these length gradations it is possible that only a small proportion of reinforcing steel strips must be tailored and that you look at almost lossless adjust the dimensions of the reinforced concrete components to be reinforced can.
  • At the preferred intervals of Position wires 3, 3 'of 500 and 1000 mm are the protrusions 4 of the reinforcement bars 250 or 500 mm.
  • the supernatants 4 are therefore chosen relatively large, so that an insertion of the Reinforcing steel strips on the supports in beams, transverse Reinforcements, beams or the like easily and without separation of positioning wires is possible.
  • the positioning wires 3, 3 'do no static tasks have the diameter of the positioning wires 3, 3 ' smaller than the diameter of the reinforcing bars 2 and are in Range from 4 to 10 mm.
  • the diameter gradation takes place in 1 mm increments.
  • the positioning wires 3, 3 ' have a smooth Surface and do not require any special material properties, so that they can consist of wire rod, for example.
  • the positioning wires 3, 3 ' are connected to the reinforcing bars 2 welded the crossing points, the position wires 3, 3 'flush with the reinforcing bars 2.
  • the distances and the diameters of the positioning wires 3, 3 ' must be taken in such a way that the reinforcing steel strip 1 one sufficient for transport, handling and laying Stiffness and dimensional stability.
  • the is Distance of the positioning wires is preferably 500 mm, and for diameters in the range from 12 to 16 mm, preferably 1000 mm.
  • the reinforcing steel strips according to the invention are laid in the following way: The reinforcing steel strips are first laid next to each other in one direction, whereby all reinforcement bars are arranged in one plane and parallel to each other are. Then the reinforcing steel strips are laid in the other, perpendicular direction, with the reinforcement bars of all reinforcing steel strips lie in one plane.
