Definitions

  • This invention concerns a divisible electrically welded mesh.
  • the invention concerns an electrically welded mesh of the type employed in building work, for instance, which is obtained during manufacture with two counterpart meshes and is then divided in two.
  • Such a mesh is produced with a plurality of lengthwise elements to which transverse elements are welded.
  • the lengthwise elements placed in an intermediate position during manufacture of the two-net mesh are located at present at a distance of three to five centimetres from each other.
  • the stub ends of the transverse elements remaining after the shearing are normally of the same length as the stub ends protruding at the outer lengthwise edges of the two-net mesh.
  • the central lengthwise elements are positioned at a distance between eight and fourteen centimetres, and advantageously ten centimetres, from each other.
  • the new mesh would not solve the problem of the application of the automatic overturning device, and on the other hand the mesh would not be symmetrical.
  • the invention arranges that the portions of the transverse elements placed between the central lengthwise elements should be sheared at two points and that a scrap segment and free intermediate space should be created.
  • the transverse elements protrude on the outer side of the mesh by about two centimetres and the central lengthwise elements are positioned about ten centimetres apart, the twofold shearing of the portions of the transverse elements positioned between the central lengthwise elements is carried out in a symmetrical position in relation to the lengthwise centre line of the mesh, thus creating a scrap segment of about six centimetres.
  • the invention is therefore embodied with a divisible two-­net electrically welded mesh to provide two symmetrical electrically welded meshes with transverse elements protruding by a determined value, which mesh is characterized in that the two intermediate lengthwise elements are positioned on each side of the lengthwise centre line at a distance substantial­ly of A+A ⁇ +B from each other.
  • the invention is also brought about with a method to obtain two symmetrical electrically welded meshes with transverse elements normally protruding by a determined value from a two-net electrically welded mesh, the method being character­ized in that a required extent of lengthwise spacing is provided between the two meshes during manufacture, the two intermediate lengthwise elements positioned at the sides of the lengthwise centre line being located substantially at a distance of A+A ⁇ +B from each other, the portions of the transverse elements positioned between the intermediate lengthwise elements being sheared at two points at a distance B from each other.
  • a two-net electrically welded mesh 10 is obtained which comprises lengthwise elements 11 and transverse elements 12.
  • the lengthwise and transverse elements 11-12 may be arranged at a constant distance from each other as in Fig.1 or at a varied distance.
  • the transverse elements 12 normally are at a constant distance, whereas the lengthwise elements 11 are either at a constant distance or at a varied distance, the two meshes 14a and 14b complying with symmetry in relation to the lengthwise centre line of the two-net mesh 10.
  • Lengthwise elements 111 positioned on each side of the centre line at a distance 13 from each other are comprised on each side of the lengthwise centre line of the two-net mesh 10.
  • the transverse elements 12 protrude by a length A and A ⁇ ; this length may vary between one or one point five centimetres and about two point five centimetres.
  • the values of A and A ⁇ may be the same or different.
  • the distance therefore has a value of 2A+B, or rather of A+A ⁇ +B, namely a value twice (2A) the value of the protrusion of the transverse elements 12 from the long outer side of the mesh plus the value B.
  • the value B which is positioned substantially astride the lengthwise centre line, is the distance which determines the two shearing points 15.
  • the value B is the value of the portions of the transverse elements which are sheared and discharged, so that the protruding stub ends having a length A remain on the meshes 14a and 14b.
  • the free space thus created between the meshes 14a and 14b enables a manipulator to be employed to overturn one of the meshes 14a and superimpose it on the other mesh 14b.
  • the spirit of the invention comprises in a variant a free space misaligned in relation to the lengthwise central elements 111, thereby embodying protruding stub ends of different lengths.
