Definitions

• the present invention relates to a starter / fm line or a corner post of a fence.
• Fence corner posts are known, for example from US Pat. No. 2,107,589, in which a wooden corner post is supported by a reinforcement element consisting of a metal profile, a tensioning wire passing through around the corner post and whose two ends are folded over themselves in the eye of a threaded rod. This tension wire is very rigid because with its ends simply folded, it resists the tension imposed by the threaded rod.
• a so-called "high tension” fence is a fence made from hard steel wire (s) or wire mesh (s) having a tension of at least 130 to 150 kg for a most commonly used wire of diameter 2.5 mm or less.
• a tightly fenced fence In contrast to fences made of mild steel wire or mesh, which can not be tightly tensioned without the wire quickly beginning to irreversibly deform, a tightly fenced fence must be made of wire mesh or simple hard wire, with a high carbon content and / or a high elastic limit.
• Such a yarn is often sold under the trade name Hi-Tensile or High-Tensile. It occurs most often in the form of crowns of 25 kg and 600 to 650 m to be placed by the installer on an unwinder at the diameter of the crown.
• An example of such a thread is the Sethetical 25 (registered trademark) put forward on the commercial documentation of Lacme for many years.
• High tensile fences are described in the "High-Tensile Wire Fencing" documents of the Northeast Regional Agricultural Engineering Service, 1987, and "How to Build Fences with USS Max-Ten200 High-tensile Fence Wire” by United States Steel, 1980. These fences rely on line stakes and on corner posts. When the line stakes are metal, it is usually stakes whose section is T-shaped or Y (the latter is also called “star”). T-stakes are for example described in US Patents 1454649 and US5042591. Y-stakes are for example illustrated in the documentation "The Waratah fencing range 2009/10" by One Steel Market Mills, 2009.
• start / end of line and poles "corner”.
• the starting posts / end of line and the corner posts must be particularly robust, to withstand, on the first day as over time, the high mechanical tension applied to this type of fence.
• a known solution is to make the starting posts / end of line and the corner posts with large diameter wooden piles.
• a disadvantage of this solution is that the wooden piles are bulky and heavy.
• wooden piles are putrescible.
• these piles by their round section or in an arc, present in the time less well anchored in the ground than metal stakes of more complex sections.
• the user must master the use of various woodworking tools including the chainsaw and a tool type pneumatic driver, thermal or hydraulic, to be able to make the joints of the wooden piles. in each other, as well as their anchoring in the ground.
• a mooring line In the case of a mooring line, it must be placed outside the fenced perimeter, which reduces the usable space from the point of view of the owner of the land, and may also pose security problems in relation to the possible passage of pedestrians coming to stumble in the mooring. Also, the use of a mooring line is not appropriate at the level of the two starting posts / end of line of a barrier passage for a herd of animals because this mooring would necessarily hinder the circulation space of the flock when it crosses the barrier crossing.
• the strut comprises a horizontal element formed by a rigid rod which occupies a large volume.
• the present invention aims to provide a starter / fm line or a corner post of a fence that avoids at least some of the aforementioned drawbacks, which is simple to mount, and which uses conventional parts, used in such volume for the realization of the fence line that their exact number is not planned to the unit close during the site preparation. These parts are subsequently manufactured in large quantities and inexpensive.
• the subject of the invention is a starter / fm of line or a corner post of a fence, comprising a first metal peg, intended to be planted in the ground in a substantially vertical position, and a reinforcing element, said reinforcing element comprising a second metal post, intended to be disposed obliquely between said first stake and the ground, and a connecting element, intended to connect a first end of said second post, placed on the ground, said first stake, characterized in that said second stake is a line stake of the fence, and said connecting member is made of fence wire.
• the fence wire is able to withstand a strong traction, greater than 200kg.
• said first stake has a U-shaped section or W
• said second stake has a T-shaped section or Y.
• Such a second stake is conventionally otherwise used as a "line" stake of a tightly stretched fence.
• said first end of said second stake which would be under the ground surface if said stake was driven into the soil in line stakes, is pointed and has a 'lower' bore for receiving said connecting member.
• said connecting element is formed by a complete loop of closing wire.
• the loop of said connecting element is closed by means of a splicer.
• said post comprises a reinforcing element disposed in the 'lower' bore of said second stake, the wire forming said connecting element being threaded into said bore relying on said reinforcing element.
• said connecting element is formed by one or more single branches in closing wire.
• the fixing of the or each wire branch is carried out using blockers.
• said post comprises a metal anti-recess piece having a U-shaped or W-shaped section, which is placed on the ground under said first end of said second stake, said anti-recess piece having a larger flat surface than the section of said first end of said second stake, said anti-embedding piece being constituted by a cut end portion of said first stake, said first stake having a pre-cut line; allowing the detachment of said anti-depression part of said first stake.
• said second stake comprises, at its second end, opposite said first end, a notch notch.
• said first peg comprises a notch intended to receive a portion of the second end of said second peg.
• said first post has a section W, the two legs of the W being sufficiently close to each other and of sufficient depth so that said portion of said second end, inserted in said notch, is disposed between the legs of the W. This prevents any accident to an animal or a child coming to rub the post at this level.
• said post comprises a protective cap, adapted to be disposed on one end of said first stake, said protective cap comprising clipping means and / or holes adapted to receive the elements necessary for mounting the post before said mounting (element reinforcement, rod and bolt, etc.).
• the invention also relates to a method of mounting a starter / fm line or a corner post of a fence, characterized in that it comprises steps consisting of:
• a second metal peg generally used as a fence line rod, obliquely between said first peg and the ground, putting in place a connecting element between a first end of said second stake, placed on the ground, and said first stake, said connecting element being made of fence wire,
• the locking step in position of said second end relative to said first stake is performed by inserting said portion of the second end of said second stake into a notch of said first stake.
• the step of locking in position of said second end relative to said first stake is carried out, on the one hand, by the friction between said second end and said first stake, and, on the other hand, by the setting place a rod and a bolt in two transverse bores of said first stake.

• the connecting element 4 is therefore arranged in a substantially horizontal plane.
• the connecting element 4 must be able to withstand significant mechanical tensile stresses. Indeed, the connecting element 4 is the element of the pole 1 which supports the highest traction force, for example of the order of 400 to 500 kg. It should be noted that the force exerted on the connecting element depends on the number of wires of the fence.
• the connecting element 4 must be arranged substantially horizontally to fulfill its function of closing the force system and oppose the ascent of the first stake 2.
