Protective barrier for winds carrying snow or sand

Abstract

Protective barrier for snowstorms, for installation near communication routes in order to prevent the accumulation of snow or sand on the road. The barrier is formed by joining several screens made of a set of blades that are arranged horizontally, superposed on one another at regular distances, joined with vertical posts by anchoring their ends to several rectangular plates that are inserted in the vertical post using a ring on the plate.

1 . Protective barrier for winds carrying snow or sand, formed by arranging in a line various screens composed by a number of strips ( 1 ) disposed horizontally and affixed to vertical posts, characterized by the fact that the strips ( 1 ) are rectangular, folded into two equal segments ( 2 ,  3 ), and each end of the strips is connected to the vertical posts by a plate ( 5 ) that contains a tubular ring ( 6 ) in its middle area to be inserted into the post, and the plate has perforations ( 7 ) at its ends in order to fasten the strips of contiguous screens, and the strips have perforations ( 8 ) in their ends arranged in position and related in structure with the perforations ( 7 ) of the plate ( 5 ). 
     
     
         2 . Protective barrier for winds carrying snow or sand, according to  claim 1 , characterized by the fact that the plate ( 5 ) will be formed by two equal segments ( 9 ,  10 ) with an angle of inclination that coincides with that of the strip, such that the concave part is positioned in the vertical post windward in order to receive the strips in this position. 
     
     
         3 . Protective barrier for winds carrying snow or sand, according to  claim 1 , characterized by the fact that the structure of the final strip ( 1 ) of the upper part of each screen is composed of an additional segment ( 11 ) to the rest of the strips that folds inclining leeward. 
     
     
         4 . Protective barrier for winds carrying snow or sand, according to  claim 1 , characterized by the fact that separator pipes ( 12 ) will be inserted into the vertical posts between the tubular rings ( 6 ). 
     
     
         5 . Protective barrier for winds carrying snow or sand, according to  claim 1 , characterized by the fact that the lower part of the screen can be free of strips, which will instead be replaced by pipes ( 14 ) arranged in the lower part of the vertical posts. 
     
     
         6 . Protective barrier for winds carrying snow or sand, according to  claim 1 , characterized by the fact that the internal structure of each vertical post is a threaded bar, said post including a nut threaded onto the upper part of said threaded bar a lower pipe, said tubular rings of the plate, separator pipes, and said strips which are mounted on the post below the nut. 
     
     
         7 . Protective barrier for winds carrying snow or sand, according to  claim 1 , characterized by the fact that the screen can be collapsed, allowing for its folding, each vertical element being composed of two bars, a lower one that is inserted into the ground, and an upper one where the structure of the screen is placed, and a joint connecting both of these bars. 
     
     
         8 . Protective barrier for winds carrying snow or sand, according to  claim 7 , characterized by the fact that the upper end of the bar that is inserted into the ground, and the lower end of the bar that forms the screen are screwed with nuts ( 18 ) that are welded in the inside of cylinders ( 19 ,  20 ) that contain in their other end fastening elements that form a joint; a fastening element ( 21 ) that protrudes from the lower cylinder ( 19 ), to fit into the middle of two receptor elements ( 22 ) that holds the end of the cylinder ( 20 ) of the upper joint, with the corresponding perforations in the lower fastening element and in the receptors ( 23 ,  24 ) for placing a through part that allows for the joint function. 
     
     
         9 . Protective barrier for winds carrying snow or sand, in accordance with  claim 8 , characterized by the fact that the upper part of said joint includes a tubular element mounted on the upper bar above said cylinder, and the lower part of the joint includes a pipe having an interior welded nut screwed onto the lower bar.
