Definitions

• the present invention relates to a metal pole, including a telephone pole. It also relates to a method of manufacturing this pole.
• the poles including telephone line support poles, are currently closed by means of a shutter insert.
• the invention aims to overcome the disadvantages of the state of the art.
• the invention relates to a metal pole comprising a barrel and a shutter of the pole head, wherein the barrel and the shutter are made of material, the shutter being formed by folded merlons of a aliasing arranged in the pole head.
• the shutter is thus produced by deformation of the material in continuity with that of the barrel.
• This closure does not require any additional connecting element, nor assembly by welding or otherwise.
• This arrangement ensures the durability of the shutter by the impossibility of dismantling parts.
• the post has a polygonal cross section, in particular hexagonal or octagonal. Other sections, such as round or oval, are not excluded.
• each face comprises a merlon.
• the invention also relates to a method of manufacturing a pole from a metal plate comprising a base, a head and two longitudinal edges, said method comprising the following steps: cutting the head to form an alternating aliasing merlons and crenels, folding the plate to join the longitudinal edges so as to form a barrel, folding the merlons to the inside of the barrel to close the pole head.
• the longitudinal edges are joined by welding.
• the shape and the number of merlons and crenellations are chosen so that, after folding, the head post does not have an orifice whose smallest dimension exceeds 8 mm.
• two sets of different merlons are formed by cutting.
• the series of merlons have different longitudinal dimensions.
• FIG. 1 represents a metal plate from which one or two posts are manufactured
• FIGS. 2a, 2b and 2c illustrate a first embodiment of a alto of the column head according to the invention respectively before folding, after folding in a view from above and after folding in side view
• FIGS. 3a, 3b and 3c illustrate a second embodiment of an alto of the column head according to the invention respectively before folding, after folding in top view and after folding in side view
• FIG. 4 illustrates a means for closing the pole head. pole head.
• a metal plate is used, for example cut in a sheet steel coil.
• the length L of this plate corresponds to the height of the post plus the length necessary to make the crenellations merlons. This length L is generally 6 to 8 m.
• the width J 1 of the plate is equal to the perimeter of the barrel.
• -A- take a plate whose width is equal to the sum of the perimeter of the base and the perimeter of the head and cut the plate longitudinally obliquely to form two trapezes 2, 4 from each of which a pole will be realized, as shown in Figure 1.
• the base and the head of the trapezoid have in this case generally a length of the order of 60 to 80 cm and 20 to 30 cm, respectively.
• the head of the metal plate is cut to form the aliasing.
• This cutting can be performed by any known device, and in particular by a thermal device, such as plasma or laser, controlled by a numerical control.
• the slotting of the slots can be performed before cutting the trapezes or after it.
• FIG. 2a shows a first embodiment of the aliasing. This cut corresponds to an octagonal post.
• It comprises two series of alternating merlons, a first series comprising merlons 6 of length LJL and a second series comprising merlons 8 of length LJ2 less than L1.
• the length of the merlons, or what amounts to the same depth of the slots, is related to the perimeter of the head after folding, that is to say the width L3_ of the plate.
• the cuts are made so that, after folding, the merlons leave only small gaps between them, in particular less than 12 mm, or even 8 mm, so as not to risk birds get into the pole. It is also conceivable to design nierions such that they overlap after folding. However, this solution is currently not preferred because the merlons are then folded at least in part sequentially, while they can be folded simultaneously if they do not overlap.
• the next step of the manufacturing process is conventionally to fold the plate, by performing in the case of an octagonal post seven longitudinal folds by means of a press brake, to join its longitudinal edges which are then secured, by example by welding.
• a protective treatment is applied to the post, in a conventional manner, such as etching followed by galvanization by immersion in a bath of molten zinc. It is advantageous to carry out this treatment before folding the merlons as this allows free circulation of the fluids.
• the last step of the manufacturing process is to fold the merlons to the axis of the barrel to close the head.
• This can be done in any known manner.
• the form and number of merlons and battlements can be chosen freely, the criterion essential is that after folding of the merlons the head of the post does not have a major orifice may cause the introduction of a bird in the post.
• the number of merlons does not have to be chosen necessarily equal to the number of faces of the polygon.
• Figure 3a a second embodiment of the aliasing of the metal plate. It has only four merlons 12 for an octagonal drum. Each merlon 12 is in fact formed here of a first portion having the shape of the merlon 6 of Figure 2a and a second portion having the shape of the merlon 8 of Figure 2a connected by a ridge 14 after plia.
• the post head After folding the merlons, the post head has an appearance almost identical to that of the first embodiment, as can be seen in Figure 3b (top view) and Figure 3c (side view).
