Definitions

  • the present invention relates to a reinforcement mat for biaxial bending for tensile 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, of which two sheets the bars are rigidly connected at their crossing points and the bars are the same among themselves Have diameters, according to the preamble of claim 1, and a method for laying them according to the preamble of claim 4.
  • Such lattice-like reinforcement mats are used to reinforce surface structures and consist of intersecting longitudinal and cross bars, which are non-positively connected to each other at the crossing points, usually welded. Some of these reinforcement mats are manufactured directly for the building according to the information in the construction plans and are called list mats. On the other hand, the reinforcement meshes are manufactured and stored in series in specified dimensions and from standardized bar cross-sectional areas. These are called bearing mats.
  • Reinforcement meshes made of steel bars crossing at right angles and connected to one another at the intersection points, the longitudinal bars having the same diameter over the entire width of the mesh, are known, for example, from AT-PS 258 542. In the area of overlap, the longitudinal bars lie bar over bar. The starting point here is the knowledge that in the overlapping area of two mats, the bars running transversely to the pushed bars should 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 ben.
  • 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.
  • a significantly larger steel cross-section is created in the joint area than is statically required.
  • the object of the invention is to select the type of reinforcement elements described above Way to adapt to practice and thus to achieve a more rational production and warehousing. Furthermore, weight should be saved in the overlaps and the correct laying of the eyes should also be controllable.
  • the method for laying such mats is characterized according to claim 4, that in longitudinal and transverse joints the two edge bars of one reinforcement mat are laid on the gap between the edge bars of the other reinforcement mat.
  • the reinforcement mat for biaxial bending consists of a set of parallel longitudinal bars 11 and a set of parallel cross bars 12. All bars have the same diameter and, with the exception of the edge parts, are at equal distances 11B over the entire extent of the mat distributed between the longitudinal bars 11 and distances 12B between the cross bars 12.
  • the distances 11A, 12A between the two outer longitudinal bars 11 or the two outer transverse bars 12, as well as between the second outermost longitudinal bar or cross bar and the third longitudinal bar or cross bar and the third longitudinal bar or cross bar are greater, namely twice as much as big as between the other bars of the mat.
  • the two edge bars of one mat 10 are aligned with the gap of the other mat 20 or 30. This means that in the case of installed mats, all the bars are arranged with the same spacing and just as much steel is used as is required by the statically calculated load. This makes it easy to determine whether the mats have been installed correctly.
