Definitions

  • the invention relates to a method for manufacturing a fence consisting of two posts standing at a mutual distance and a lower and upper beam with a mesh of intersecting wires supported therebetween.
  • Such a fence is commonly used as site perimeter fence, i.e. the bottom ends of the posts are each placed in a foot such that a number of site fences can be disposed adjacently of each other to bound a construction site or the like.
  • site fence must have a determined bending stiffness to be able to realize the desired protection and for this purpose the section filled by the intersecting wires is also bent into zigzag shape to obtain a determined bending stiffness.
  • Other stiffening measures can also be applied, such as additional wires and the like.
  • the invention has for its object to change the method for manufacturing the fence such that the stiffness is obtained through a pretensioning.
  • the method according to the invention is distinguished by:
  • the desired pretensioning of the section can be obtained by placing the section of the intersecting wires under a tensile strain by means of the beams and/or the posts.
  • the beams and/or the posts can be pressed or pulled apart after arranging of the edge strip of the section and be attached to each other in this loaded position.
  • This attachment can take place according to the invention with a butt weld, which enables a preparation of the components against corrosion without the protective layer then being damaged again.
  • the site fence according to the invention consists of two posts 1 which are mutually connected at the top and bottom with an upper respectively lower beam 2, 3, between which a section of intersecting wires 4 is arranged.
  • the posts protrude below the lower beam, whereby they can be placed in a hole of a site fence foot. It is thus possible to connect a number of such site fences to each other to obtain a continuous fence.
  • the section 4 consisting of longitudinal wires 5 and transverse wires 6 is first manufactured in accordance with the known method wherein the transverse and longitudinal wires can be mutually welded to each other.
  • Other sections of intersecting wires are possible within the scope of the invention.
  • An edge strip is created along the four sides of the section by means of the outer longitudinal respectively transverse wires 5', 6'.
  • the posts and beams consist here of pre-drawn profiles, this such that the wall of a tube profile 7 is provided with an inward fold 8.
  • the fold is such that the entrance is narrower than the thickness of the fold itself, see fig. 3.
  • the entry slit of the fold has a width which is not much more than the thickness of for instance the transverse wire 6 respectively longitudinal wire 5.
  • the fold widening towards the inside can however accommodate the intersecting wires, the longitudinal edge wire 5' and transverse wire 6.
  • Beam 2 is pushed on one side over the edge strip of the section as according to arrow P1 in fig. 2 so that the longitudinal edge wire 5' is received in the fold.
  • the posts 1 are then pushed in the same manner over the edge of the section such that the transverse edge wires 6' come to lie in the folds thereof, see also fig. 5.
  • the section is thus wholly enclosed along the edge in tubular profiles.
  • Fig. 6, 7 and 8 show a possible drawing machine for placing beams 2 under tension, this drawing machine consisting of a supporting beam 10, 11 on which a catch 12 is arranged in which the transverse wires are held fast.
  • a tensile stress can be exerted on the beams by moving the left-hand catch 12' in the direction of arrow P3.
  • the ends of the beams 2, which are optionally pretreated, then only have to be welded or butt-welded or otherwise against the sides of the posts.
  • the invention is not limited to the above described embodiment. It is thus not necessary to make the section from intersecting wires which run parallel to the posts respectively the beams. Use can also be made of interwoven sections.
  • the fold only has to have a narrowing entry slit such that the thickened peripheral edge of the section can be received therein and a tensile force can be exerted.
