Disclosure of the Invention The present invention is a structural poles technology, with any geometry (cylindrical, conical, octagonal or parallelepiped or other form that the user wishes to manufacture), made from a composite of matrit. thermoplastic, or thermosetting, glass-fiber reinforced carbon fiber, in percent to be determined according to. the rigidity required for the stress to which it will be subjected, by filamentary winding or by pultrusion, depending on the section of the pole, whether or not it is uniform. The use of a mandrel to shape the post may be replaced by use of another shape, cone, parallelepiped, of apo or other rigid material, even · in composite, which will be reinforced by the filamentary winding process.

If. the post was exposed to fire. use of plnturae. dumes cantes, its involvement by the exterior with layers, 1.1 of rock or. other fire-resistant material. Because large posts can be easily transportable and manoeuvrable, they can be constructed in small sized portions attachable to each other at the ends by screws, dowel, or other simple means. Alternatively, the different sections can still be connected: by manual injection, in order to perform a structural weld. The developed technology is essentially comprised of: a cylinder or cone trunk with smooth octagonal geometry or another shape intended by the user (1) in thermoplastic or thermosetting material, reinforced with glass and carbon fibers, produced with the use of filament winding technology, or pultrusion. For some post strength / height combinations this solution is sufficient. When the height of the pole is raised and / or the major efforts, it may be necessary to increase the stiffness of the post through a sandwich-like construction. In this latter case, two cylinders or trunks of conical or octagonal cones are produced. . two different diameters so as to allow a gap between them when placed on the same axis, the play being subsequently filled by an expandable foam (for example polyurethane); The post may be enveloped by a layer of flame retardant material (eg rock wool (2)), or painted with int. which will protect it against very high temperatures; - during the production process of the support for the transport of electric power (pole), small steps are placed as inserts so as to enable them to climb by authorized personnel (5). Fixation may be provided for. fire detectors (.6) and respective emitting antennas (7); - the top of the support is closed (10) by removable cover, so as to enable the installation of: 9-line support equipment, or other lighting equipment: other equipment that the user understands; - at the ends of the crosspieces and a carton is placed. an electronic device, controlled by. distance from the base, or from the base of the stand .21):,: which acts as a seizator / switch, transmitter between posts, in order to cut the energy between the line upstream and downstream of the support, as well as: give an emergency warning, - an internal ground wire, so as to ensure electrical discharges £ 11.); (12) for allowing the passage of conductive wires, by the support so that it can be electrified, when the user thus: needs it, this opening being able to be replaced by another access device , which is of convenience to the user, or by future technical standard:; - For poles of reduced structure or where the sole purpose is insulation or color, existing steel approved poles may be used, wrapping them externally by layers of thermoplastic or thermoplastic matrix, by use of the steel filament winding; - Fittings for. horizontal and vertical conveyors, so that the conveyor can be used for large poles intended for the transport of electrical energy (1.3 lbs)

These sleepers may be of the same composite material used in the manufacture of the pole and shall comply with the regulatory standards for the transportation of overhead power lines approved by the sector regulator and the local Distributor if applicable. innovative and are the support of wind turbine and s,

The main uses of these transport posts: of electrical overhead lighting fixtures, urban equipment, emergency detection support and distance communication by interface between the poles.

If the post is fabricated using a sandwich construction " its core can be made up of expandable foam (4) in order to provide the necessary support for the rigidity required to meet the requirements of the arrow, which is maximum permissible for the use to which it will be subjected, namely the transport of Low, Medium and High Voltage.

This post may be pigmented to the color the user understands, through a " bath " of composite material that gives it a smooth and colorful texture.

This post is recyclable.

This invention solves the problems related to the placement of supports in difficult to reach areas, since their. low weight and modular assembly (by trammels) make it easier to transport, reduce the damage caused by the modifications of the Medium and High Voltage lines, as well as the 11 rations leading to it. vertical.

There is still the risk of electrocution because the pole is manufactured by isolating material.

It also sees: the problem of color durability; since current concrete and steel technologies need to be painted externally to match the color desired by the galvanized steel, since the galvanized steel does not allow the paint to adhere to the structure and the concrete has a high absorption rate of the paint which causes it to disappear after a short time, thus necessitating a high maintenance.

It also solves the Problem of Voltage Work, or Voltage Proximity, given the electronic cut-off device by remote control.

It also solves the problem of fault detection, as it has electronic warnings that identify the voltage cut between the lines a. amount and: as long as the · post supports cl '' Resolve q. problem of security There are cities and roads, given the electronic device: coimmiçante, inserted in the support (po.r example of illumination: publishes) between the post and its three rides.

Resolves the situation of intrusion in large properties: given that the post is equipped with an electronic device, capable of notifying the user of the intrusion on his property, in a space of up to 1QD meters comprised between supports. 12

It solves the problem of the stiffness of the remaining composite rests in the process by introducing the reinforcement of the matrix of the matrix or term. with carbon fibers, is combined with the traditional glass fibers. The height of this cylinder can vary according to the intended use, from urban equipment to wind turbine towers or other mechanisms requiring lifting with support. Method of Manufacture

This pole is manufactured from a thermoplastic or thermosetting matrix (for example polypropylene, or natural or epoxy resins), fiber-reinforced (e.g. glass and carbon), transformed with the use of the filament winding technique, or pultrusion. The size and degree of winding of the fibers varies according to the use that the support will have. For structural posts intended for urban equipment and luminaire support, intended for public or private lighting, a lighter winding will suffice for one, post with the height of δια, for example, a larger quantity is already required for, for example, the production of a 25m post subject to "head" efforts.

In the manufacture of this post, fiber optic cables and / or sensors may be used, depending on the purpose for which they are intended, whether for intrusion detection or emergency communication, or simply for the detection of local malfunctions.

For structural posts intended for the transport of electrical energy. also varies according to the efforts. to which support I will be subject.

For special posts subject to a high risk of fire, the support may: be surrounded by materials, igniters,

Advantages of the invention The present technology allows for the manufacture of poles which can easily be: transported, with less technical means " than those currently required to carry the conventional posts on the market, as well as being present from ineligible posts, which will increase the security of the environment and human, given their ability to communicate at a human interface distance, or radio-frequency, GPRS, GSM or other suitable receivers / transmitters, depending on the location in which the post is to be installed.

The thermoplastic matrix prepregs used in the manufacture of the composite posts have as a great advantage, in reliance on other traditionally used materials, the fact that they have a higher mechanical strength associated with a low weight. Thus, it is possible to use this technology in the transport of overhead lines, support of wind towers, lighting and urban equipment, without restriction of:.

As the geometry of the poles makes them resistant, it is not necessary to mount them with preferential orientation taking into account the direction of the tension lines: this technology 14 avoids the upstream and downstream modifications of the support when it has to The low weight allows transport and flying without the use of special technical means, thus facilitating their placement in difficult areas. access. Λ The possibility of incorporating pigment during manufacture also allows for easy coloring according to the user's preferences. The use of thermoplastic matrices also makes the support completely recyclable. The pole, because it can be divided into sections of suitable length, allows an easy transport and without the use of special vehicles. Protection, when necessary, can be achieved by using inks or by wrapping the backing with flame retardant materials. This technology allows the support to be lifted from any height, thus providing all types of supports or towers: support used in existing or future technologies that need or will require support for support.

There is also the advantage of being able to acquire several shapes since the composite can acquire different sections through the use of mandrels with different geometries and of easy execution, in the wind, lament: filaraentar.

When the construction is carried out by incorporating supports · in other rigid material, such as steel, inside it, it is possible to use supports approved in steel, with. reduced cross-section relative to the original in use without this invention, still having the additional advantages of being surrounded by composite material in order to eliminate the risk of electrocution and to confer permanent colors. The incorporation of sensors, receivers and compatible transmitters by human interface, or by environmental or structural changes, makes this support unique in the world and of great public and private utility. With this support, high levels of safety will be achieved, as well as avoiding undesirable environmental disasters. nisboa, May 11, 2Q11
