Definitions

  • the invention relates to a fence of the type corresponding to the preamble of claim 1.
  • the holding elements consist of clamping tabs made of flat iron, which are distributed over the height of the lattice panel on the front of the post and are connected to the post by a series of screws which are in rivet nuts in engage the post. The ends of the adjacent lattice panels are clamped between the small flap and the front of the post.
  • the "front of the post” is to be understood as the side of the post on which the lattice panels are located.
  • the lattice panels consist of 4 mm to 12 mm thick rods made of iron wire, which form a right-angled lattice and are connected to one another at the intersection points by resistance welding.
  • the grids are provided with rust protection after welding.
  • the bars run horizontally and vertically.
  • the aforementioned features are also present in the preferred embodiment of the invention, but they are not mandatory.
  • the bars do not have to be made of steel, nor do they have to run vertically and horizontally. Lattices with oblique lattice bars also fall under the invention.
  • a fence on which the preamble of claim 1 is based is known from FR-A-24 29 309.
  • the posts consist of a rectangular hollow profile with a rear slot, and the hooks are embossed from the front of the profile.
  • the latching of the hooked grid panels consists in that the stamped hooks are bent with a hammer blow above a horizontal stack of a grid panel.
  • embossing of the hooks requires a slot on the back of the profile, which significantly affects the stability of the posts. Embossing is also complex.
  • the embossed hooks and in particular the method of locking are unfavorable for corrosion protection because the protective layer cannot form properly at the embossed points and is destroyed in many cases when deformed by the hammer blows.
  • the invention has for its object to improve the locking of the grid panels in the hook.
  • the lattice panels can be attached to the post to a certain extent and the locking can be accomplished while protecting the corrosion protection layer on the hook and the detected lattice bars. It is enough off if the locking is only provided at one point of the height of the post or the lattice panel.
  • the hooks are intended to support the otherwise self-supporting, ie the dimensionally stable, lattice panels.
  • a particularly stable locking results if the locking screw also passes through an eyelet at the free end of the hook in the manner shown in claim 2.
  • the screw can also engage only in the front of the post.
  • the hooks can be butt-welded onto the front of the profile material (claim 4).
  • the profiles can be both open profiles in the form of U-profiles or I-profiles, but can also consist of closed hollow profiles.
  • Another possible embodiment includes posts made of grid material, as is known per se from DE-U-69 o5 441.
  • the strips of lattice material forming the posts can be delimited in parallel or can be wider at the bottom for reasons of stability.
  • the hooks can in this case be formed by horizontal bars projecting from the front of the post thus formed and bent upwards.
  • Formations of posts made of grid material that are particularly suitable for the invention are the subject of claims 6 and 7.
  • the fence 100 consists of lattice panels 1, 1 'of a rectangular lattice of horizontal bars 2 and vertical bars 3 welded to one another at the crossing points in the manner of a structural steel mesh mat.
  • the lattice panels 1, 1 have a length of, for example, 2.5 m in the horizontal direction and extend from one post 10 to the next. They consist of iron wire with a diameter of 4 mm to 12 mm and are dimensionally stable, i.e. stable in itself, so that they do not require any additional means to stabilize the fence area, as is necessary in the form of the tension wires in fences made of flexible wire mesh.
  • holding elements 5 of which only two are present in FIG. 1 over the height of the post 10, one of which acts on the lowest horizontal bar 2 and the other on the second uppermost horizontal bar 2 .
  • more holding elements can also be distributed over the height of the posts, for example one for each individual horizontal bar 2.
  • the design of the posts 10 and the holding elements 5 can be seen in detail from FIGS. 2 and 3.
  • the posts 1o consist of a hollow profile of square cross-section, which is covered at the upper end by a cover plate 6 which protrudes to the side of the lattice panels.
  • the holding elements 5 are formed by rectangular hooks 7 made of round material with a perpendicular to the fence surface extending legs at 8 butt welded to the front wall 9 of the post 1o in the manner of the stud welding.
  • the lattice panels 1 rest on the hooks 7 with the horizontal bars 2, 2.
  • the free legs 17 of the hook 7 extend upwards.
  • the free leg is formed into an eyelet 11 which is parallel to the fence surface and through which a screw 12 extends which also engages in a blind nut 13 in the front wall 9 of the post 10.
  • the grid plate 1 is prevented by the screw 12 from exiting the hooks 7, 7 'upwards.
  • the screw 12 thus forms a locking device for the lattice panel 1. It only needs to be present at one point on the height of the post 10.
  • FIG. 5 shows another embodiment in which two hooks 7 are attached to a post 10 next to each other at the same height.
  • the lattice panels 1 and 1 'do not have to end on one side between the last two vertical bars, but there is securing in the horizontal direction by the arrangement by the terminal vertical bars 3''' between the hooks 7. The locking takes place as in the embodiment 1 to 4.
  • the posts 2o consist of upright strips made of a lattice material, which are arranged perpendicular to the lattice surface.
  • the post 20 comprises vertical rods 23 which are parallel to one another and which are each arranged two opposite one another on both sides of horizontal rods 22. At least two of the horizontal bars 22 ′ protrude to the right, as shown in FIG. 6, over the right vertical bar forming the right delimitation of the post 20 and form hooks bent upwards there, which have the same function as in FIGS. 2 to 4.
  • the second uppermost horizontal bar 22 '' of the post 2o has a hook 7 'with an eyelet 11, which corresponds to the eyelet 11 in FIGS. 2 and 3.
  • the screw 12 passes through the eyelet 11 and the two vertical bars 23 of the post 2o adjacent to the lattice panels 1, 1 'in order to be screwed into a nut 13 on the rear side thereof.
  • the fence post 2o 'of FIG. 9 corresponds to the fence post 2o with the exception that the horizontal bar 22''has no hook 7' and no eyelet but ends straight to the right of the terminal vertical bar 23 of the post 2o '.
  • the lattice panels are overlapped at the upper edge by a screw 12 ', which is offset upwards by the thickness of the horizontal bars 2, 2 relative to the horizontal bar 22''and screwed into the nut 13 and has a protruding head 14 which extends from the outside in front of the top horizontal bar 2 of the lattice panels 1, 1 '.
  • the horizontal bars 32 of the fence post 3o are designed as U-shaped brackets located in a horizontal plane, to which the vertical bars 23 are welded on the outside and which protrude beyond the right vertical bars 23 in order to form the hooks 7 there .
  • This embodiment is somewhat more stable than that of FIGS. 6 to 9, in which the horizontal bars 22, 22 ′, 22 ′′ lie to a certain extent in one plane.
  • the lattice panels 1, 1 'at the ends as well as in FIG. 5 can be cut off smoothly again, the terminal vertical bars 3' '' being arranged between the hooks 7, 7.
  • the lock comprises a plate 15 welded between the right vertical bars 23 of the post 3o, against which the two end vertical bars 3 '' 'of the lattice panels 1, 1' according to Fig. Lo lie from the right.
  • a clamping disk 16 from the right, which is tightened by a screw 12 against the plate 15.
