Definitions

  • the invention relates to a reinforcement mat for reinforced concrete, consisting of longitudinal elements that cross each other and are welded to one another at the crossing points, preferably ribbed or embossed, and of transverse wires, zones on the two mat edges with at least approximately half the width of the mat compared to the inner area of the mat related steel cross section are provided.
  • Reinforcement meshes are known in a variety of different configurations. They can be produced directly in the desired length or can be separated from lattice webs which are wound into rolls and are produced in great length. However, the mat width is limited to 2 m to a maximum of 2.4 m due to the need to have to transport the mats on vehicles.
  • This width limitation makes it necessary to lay mats next to each other when reinforcing tensile structures, at least in one direction.
  • the edges of adjacent mats must overlap each other so far that the forces from the cross wires one Mat can be transferred into that of the neighboring mat.
  • zones are provided in the so-called edge saving mats on both mat edges with at least approximately half the steel cross-section compared to the inner area of the mat, related to the unit width, so that if there is an overlap, adjacent ones Mats around the width of these zones over the entire reinforced area result in steel cross-sections of the same size.
  • the invention is therefore concerned with the task of designing edge-saving mats of the type specified in the introduction which, when covering their weakened edge zones with regard to the steel cross-section, result in a uniform distribution of the related steel cross-section over the entire reinforced area, in such a way that the mats can also be laid in a controllable manner with a greater coverage can be made without having to accept steel losses.
  • This object is achieved in that symmetrical to the longitudinal center axis of the mat at a distance from the mat edges, which is greater than the width of the edge zones reduced related steel cross-section, a longitudinal reference element distinguishable from the other longitudinal elements of the mat is arranged, which limits a larger coverage zone , if they are observed due to the increased ratio between Cover width and distance of the longitudinal symmetry axes of the covered mats, the steel accumulations in the cover area can always be taken into account as being evenly distributed over the reinforced area.
  • the distance between the two longitudinal reference elements from the mat edges should be between 1/4 and 1/6 of the mat width and should preferably be at least approximately 1/5 of the mat width.
  • FIGS. 1a and 1b parts of edge-saving mats according to the invention, the edge zones of which overlap to form a so-called distributor joint;
  • Figures 2a and 2b parts of the same mats as Figures 1a and 1b, but with a much larger, controllable coverage, in which the steel accumulation can be included in the coverage area;
  • FIGS. 3a and 3b show another embodiment of edge saving mats according to the invention.
  • the edge-saving mats shown in FIGS. 1 a, 1 b, 2 a and 2 b all have longitudinal elements of the same cross section. All the longitudinal elements labeled 1, like the two edge longitudinal elements labeled 1a, are individual wires on each mat edge. At a distance A from each mat edge, longitudinal elements 1b are further provided, which are formed by two mutually touching wires half cross-section, so that they are distinguishable from the other longitudinal elements and can serve as reference elements. While all the longitudinal elements are arranged at a mutual distance / in the interior of the mesh, the two longitudinal edge elements on each mesh edge are twice the distance 2a from one another and from the next longitudinal element 1. The longitudinal elements 1, 1a and 1b are at a distance from one another with transverse wires 3 serving as distribution reinforcement Welded mesh mat.
  • the edge saving mat according to FIGS. 3a and 3b again has longitudinal elements in the form of equally spaced individual wires 1 and, as reference elements 1b, two half-cross-section wires touching each other. Two longitudinal elements 1d half cross-section are arranged in each of the two edge zones. All these longitudinal elements have the mutual distance a.
  • the ends of the transverse wires 3 connecting the longitudinal elements protrude beyond the outermost edge wires 1b and are bent back in the form of loops 4 and preferably also welded to them.
  • FIGS. 4a and 4b represent parts of edge-saving mats according to FIGS. 3a and 3b with coverage of the edge zones. It can be seen that in the overlap area the edge longitudinal wires 1d half cross-section of both mats complement each other in pairs to form longitudinal elements of the same cross-section as the longitudinal elements 1 and 1c, so that this overlap again results in a uniform distribution of the steel cross sections as seen in the top view according to FIG. 4b. Compliance with the correct overlap can be clearly recognized by the relative position of the loops 4 in the overlap image according to FIG. 4b.
  • FIGS. 5a and 5b again show the case of large overlap, in which the outermost edge wire 1d of each mat overlaps the reference element 1b of the other mat. Compliance with this requirement is.
  • the relative position of the outermost longitudinal longitudinal wire 1d of one mat, clearly marked by the loops 4 can be checked with respect to the double wire 1b of the other mat, which serves as a reference element.
  • the steel accumulation shown in FIG. 5b in the overlap area can be invoiced as being distributed uniformly over the entire reinforced area.
  • the reference elements can be differentiated from the other longitudinal elements in another way, for example by designing them as parallel wires with welded crossbars.
  • the outermost longitudinal longitudinal wires 1d can also be made distinguishable from the other longitudinal elements in a different way than by the connection with bent-back transverse wire loops 4; for example, they can also be designed as half-cross-section longitudinal wires touching each other.
