Definitions

  • the present invention relates to a reinforcement element for surface structures made of reinforced concrete with a first set of parallel bars in the longitudinal direction and a second set of also parallel bars in the transverse direction, which are connected at their crossing points and the bars of each share have the same diameter, and a method for Laying the same and an application of a special embodiment.
  • Such lattice-like reinforcement elements are used to reinforce tensile structures and consist of longitudinal and cross bars crossing each other, which are non-positively connected to each other at the crossing points, usually welded. Some of these reinforcement elements are made directly for the building according to the construction plans. These elements are summarized under the term list mats. On the other hand, the reinforcement elements are manufactured and stored in series in defined dimensions and from standardized bar cross-sectional areas. These elements are called bearing mats.
  • the bearing mats are divided into E-networks for single-axis bending with bars with a larger cross-section in the longitudinal direction and bars with a small cross-section in the transverse direction and Z-networks for two-axis bending with bars with at least approximately the same cross-sections in both directions.
  • E-networks for support reinforcement, W-networks for wall reinforcement and K-networks for constructions are also known.
  • Reinforcement mesh made of steel bars crossing at right angles, which are connected to each other at the crossing points, where the longitudinal bars are the same across the entire width of the mesh che diameter, are known for example from AT-PS 258 542. In the area of overlap, the longitudinal bars are then bar over bar. This is based on the knowledge that in the overlapping area of two mats the bars running transversely to the pushed bars must have a larger number. With this covering of bars, the steel cross-section is correspondingly twice as large as would be required for static reasons, ie after loads and bending moments.
  • CH-A 394 568 and 482 884 for example, two embodiments of reinforcement elements for electrical networks are described.
  • the mats are made larger by the amount that the covering requires when the mats are laid next to one another in order to ensure a certain minimum covering.
  • the object of the invention is accordingly to adapt the type selection of reinforcement elements of the type described in the introduction to practice and thus to achieve a more rational production and storage. Furthermore, weight should be saved in the overlaps and the correct laying of the eyes should also be controllable.
  • this is achieved for a reinforcement mat for uniaxial bending in that one edge bar of the coulter is arranged on both sides in the longitudinal direction at a distance twice as large as the other bars of this coulter, and that on both sides two edge bars of the coulter in the transverse direction are arranged at a greater distance than the other bars of this group are arranged.
  • a reinforcement mat for biaxial bending is characterized in that the two outer bars of the coulter are arranged in the longitudinal direction at twice the distance as the other bars of this coulter, and that the two outer bars of the coulter are omitted in the transverse direction.
  • the method for laying such meshes is characterized in that the reinforcement elements are laid overlapping by at most the mass of the edge parts, determined on the one hand by the larger rod spacing and on the other hand by the dimensions of the rod ends projecting outwards, and the use of the second type of reinforcement mesh as Wall reinforcement is characterized in that the bars of the coulter are halved in length and upright in the longitudinal direction, such that the parts projecting freely outwards are used for connection to reinforcement elements of the floor above.
  • the reinforcement network for uniaxial bending consists of a group of longitudinal bars 10, which fulfill the function of the supporting reinforcement and a group of cross bars 11 with the function of a distribution reinforcement. It follows that this type of reinforcement mesh is used for the reinforcement of uniaxially tensioned tensile structures.
  • the outermost longitudinal bar is arranged at twice the distance, these are the two outermost cross bars in the case of the cross bars 11.
  • joints in the longitudinal direction according to FIG. 3 are also arranged.
  • the cross bars 11 of one reinforcement network 14 are centered on the gap of the other reinforcement network 15. This results in a compression in the longitudinal direction with respect to the number of cross bars.
  • Breakage of steel in the joint and, in the case of longer lengths, a cracking off of the concrete cover, on the other hand, with these lengths, a steel break next to the joint can be determined.
  • the reinforcement network for biaxial bending according to FIGS. 4 to 6 serves to absorb tensile forces in both directions. This means that the overlaps of two nets arranged next to each other are always to be designed as load-bearing joints.
  • the longitudinal bars 41 are laid in the edge area at twice the distance 41B as in the field with the distance 41C and the cross bars 42 are not present in the edge zones, so that an edge 42D corresponds to the distances 42C in the field.
  • the joints must be as specified above.
  • the upper edges of the longitudinal rods 41 each cover two transverse rods 42, so that, viewed in this direction, the transverse rods 42 are evenly arranged.
  • the reinforcement network thus contains 30 cross bars 42 and 18 longitudinal bars 41 .
  • the joint length in the transverse direction is thus 350 mm and in the longitudinal direction 500 m. These dimensions also correspond exactly to the optimal joint lengths.
  • reinforcement networks for biaxial bending, the entire practically occurring area of application can be covered.
  • these reinforcement nets can also be used for wall reinforcements in building construction, in that the overhangs of length 42D into the connection area one; Floor or ceiling reinforcement must be installed. Halving this reinforcement network results in two identical half networks.
  • the weight saving in the joint areas is optimal in that the weight of two cross bars 42 in each case in the longitudinal direction and 1/3 in each case in the transverse direction can be saved.
