Description
BARRIER PROTECTOR DE LAS VENTISCAS
Field of the Invention
The present invention refers, as expressed in the statement of this specification, to a barrier designed to protect communication routes, such as railways, roads and highways, from snow or sand accumulations that transport blizzards. , propitiating that the wind does not hit the road directly and causing the deposit and stacking of the materials it carries out outside of it.
Background of the Invention
Various ways of protecting these roads against blizzards are known. The most traditional are wooden barriers with boards arranged horizontally at regular distances from each other, which are fixed to vertical posts to form a fence.
Other barriers combine in the configuration of the fence metal posts that sit on the ground in the vertical along with plastic or synthetic materials for the horizontal elements. It is also known the mixed fence composed of wooden planks and steel poles. U.S. Patent 353,206 claims the ornamental design of a fiberglass snow fence; This barrier has a degree of leeward inclination with complementary posts supports in this area.
Ref .: 219562 The American patent 3,966,172 shows us a protection device on the windward and leeward sides, formed by two barriers that rest one on the other at the top and composed of a plurality of planks or horizontal slats with Vertical posts, with anchors to the ground by cables.
It is also known plant protection against blizzards, which is carried out through the planting of trees, shrubs or plants, with a provision of one or more lines in the conformation of the barrier. The drawback of this system is that the vegetation is useful when it has a certain height, not when it reaches a greater height or when it has a smaller size.
Brief Description of the Invention
The proposed invention consists of a barrier against the blizzard composed of a set of pieces that are easily transportable to the place of location, to configure a barrier by the online arrangement of a plurality of screens. The structure of the elements that make up the invention ensure that its installation on site as well as the change of damaged parts, in the maintenance and repair work, are done quickly and easily.
Each screen consists of a set of slats that will be placed horizontally, overlapping each other at regular distances, linked to the vertical posts by anchoring their ends to rectangular belay plates that are inserted into the vertical pole by a tubular ring presenting the structure of the plate.
The line of screens that make up the barrier will force the wind to pass through its structure, dissipating its speed and avoiding whirlpools in the protection zone, which are drivers of accidents to drivers by making it difficult to see the road.
The screen will have a wind deflector in its upper part that will propitiate the channeling of the wind path so that the precipitation of the materials it carries is carried out past the protection zone.
In this way, the installation of the invention in the field will eliminate the deposit of snow or sand in the road, causing a pile-up divided between the anterior zone of the barrier, windward, and off-track in the leeward part.
The lower part of the screen will be shown free of slats in order to minimize the deposition of snow in the region immediately after the screen, in the leeward zone.
Additionally, the screen may be presented with a joint in the lower part that allows the prostration of the screen towards one of the sides or towards both, with its total abatement on the ground in times where this protection is not necessary and it is desired to eliminate the visual impact that these barriers pose in the landscape; facilitating the articulation, also, the repair work.

Detailed description of the invention
Referring to the figures shown, it can be observed how the barrier object of the invention, Figure 1, is configured by joining several screens that are placed on the ground by vertical posts. Each screen is composed of a plurality of slats that adopt a rectangular configuration (1), arranged horizontally, one above the other and with some overlap between them, to form the screen in the fastening of its ends to individual vertical posts that settle in the field (Figures 2 and 3).
The profile of the slats has a longitudinal fold in its central part with two identical sections (2,3) of 191.77 mm, forming an angle of 170 °; advantageous configuration that will endow it with wind resistance. The screen will be arranged on site with all the slats in the same position, with its concave part towards windward, side of the barrier that receives the wind represented by the arrows (Figure 1 and 2).
All the slats contain on the edge of their major sides a fold (4) that will protect the edges of the lama from oxidation, as well as the operators of cuts in the work of installation or repair.
The linking of the slats with the posts is done by means of a rectangular plate (5) of slightly lower height than the slat and folded into two sections (9, 10) with the same angle of inclination as the slats of the screen. This plate is inserted into the post by means of a tubular ring containing each welded plate in its middle zone (6), of appropriate section to be introduced in the vertical post, the ring having a height of 110.00 mm.
The plate has four holes horizontally cut on each side (7), to secure by screwing the slats that also have four holes (8) in each of its ends related in the position and size with the holes of the plate . This link of the plate and the lama can be seen in Figures 8, 9 and 10.
On each side of the plate the ends of slats located in adjacent screens will be fixed, to form a protective barrier in this form of union, as detailed in Figure 11.
In Figure 1, at the ends of the barrier the securing plates do not appear in their entirety, but only up to the ring (6) that is anchored in the vertical post. This is because they will be placed for aesthetic and safety purposes for bystanders circulating in the area, these end-of-barrier securing plates, without the protrusion that this plate would suppose without receiving any slats.
Similarly, in Figures 1 and 2 a single screen showing the barrier end securing plate (5) is shown in these figures, it being understood that on each screen, except at the ends of the barrier, the plate will be installed. of entire belay (5) that will allow the anchoring of the slats of the following screen.
The last slat of each screen will contain an additional section (11), being arranged bent inclined towards leeward at a 90 ° angle, which will serve as a wind deflector. This baffle section will be of less height than those of the slat, 150.00 mm.
The slats will be installed on the screen equidistant from each other on the vertical posts, keeping this distance by the contest of spacer tubes (12) that are inserted into the posts between the tubular rings of the slats (6), determining the degree of overlap between these the height of the tubes, at a lower height, higher level of overlapping between slats; presenting in this mode of preferred embodiment a height of 177.34 mm.
The position of the securing plate (5) with respect to the tubular ring (6) will determine the degree of inclination of the slats on the screen. They will be manufactured, preferably, so that the section of the slats placed in leeward forms an angle of 65 ° with respect to the horizontal plane (Figure 12).
The internal configuration of the vertical posts that act as support for the screen will be threaded rods (13) driven into the ground, preferably Gewi bar of 2000.00 mm. Tall.
The lower part of the screen will be presented without slats; they will be replaced by the introduction in the vertical poles of tubes (14) with the desired height of this gap. The optimal size of this space from the floor to the beginning of the screen is between 10 to 15% of the total height of the screen.
The section of these lower tubes of the screen (14) will be the same as that of the separator tubes between slats (12), and that of the tubular ring that is presented in the slat securing plates (6).
The screen will be closed at the top by means of a nut that will be screwed into the bar that makes up the vertical pole (15).
The screen may present a joint in the lower area of the posts that allows its folding. In this case, each vertical element will be configured by two bars with threaded structure (16, 17), Gewi, related by means of a joint (Figure 13).
The lower bar (16) will be introduced into the ground, and in the upper (17) the screen will be formed, the articulated joint being by threading the bars in separate nuts (18) welded inside of cylindrical pieces (19, 20), as shown in Figure 16, which have at their other end engagement elements to form the joint, one (21) that will come out of the lower cylinder (19), to fit in between two receiving elements (22) containing the end of the cylinder (20) of the upper joint. The lower engagement element (21) and the receiving elements (22) have associated perforations in their position (23, 24), intended to receive, once the lower coupling is installed in the receiving elements, a through-hole, preferably bolt, securing the joint in a nut (25). The upper part will be additionally protected by a tubular hyperboloid element (26) installed in the bar above the cylindrical part (20) that will serve for the transition of dimensions between it and the bar in the joint. Likewise, the lower part may be protected by a tube (27) inside which a welded nut will be arranged.
The screens will be fixed by cables that will be placed on the top of the poles to be secured in the leeward and windward terrain (Figure 1). Another alternative way will be the placement of rigid pipes in the same position as the cables but located only on one side of the barrier. This modality will be preferred when the poles have a lower articulation.
The barrier will be installed preferably parallel to the road to be protected, in the ridges of hills, in windward areas of stream channels and other topographic depressions that allow the increase of the snow deposit of the screens, making a preliminary study of the winds predominant in the area in a period of time sufficient to obtain an adequate statistical value of wind directions and which or which are the most predominant over the rest.
The accumulation of sand or snow will be in the windward and leeward zone, outside the area protected by the invention.
The barrier without openings in the protection line will be arranged; in cases where the provision of openings is unavoidable, some screens must overlap with others of the same line, or several lines of screens will be arranged.
It should be understood that the invention has been described according to the preferred embodiment thereof, so that it may be susceptible to modifications of shape, size and materials, provided that the alterations do not substantially change the characteristics of the invention that are claimed below.
It is noted that in relation to this date, the best method known to the applicant to carry out the aforementioned invention, is that which is clear from the present description of the invention.
