Definitions

  • the present invention relates to a system for fixing armor on flat surfaces, and particularly for the ballistic protection of walls and roofs of military shelters.
  • the purpose of shelters is to protect delicate telecommunications equipment from the environment in which it is installed. In particular, they protect such equipment from the weather and from excessively high temperatures, normally being equipped with air-conditioning systems when they are exposed to direct solar radiation, especially if they are installed in tropical regions.
  • shelters When such shelters are used for military purposes, they are also used to protect said equipment from damage caused by bullets from firearms or splinters from grenades exploding in the immediate vicinity.
  • the armor plating is very heavy, it is preferably transported in separate pieces and assembled on the shelter after it has been installed. That is why fixing means suitable for being assembled simply with bolts are generally used.
  • armor in the form of quadrangular plates are fixed to the outside of walls and roofs, strips of ballistic steel being added so as to cover the juxtaposed edges of adjacent plates.
  • strips are attached to two consecutive sides of each armor plate, but not to the other two sides.
  • Each armor plate can thus be juxtaposed on two of its sides (the sides complete with strips) with two other armor plates, protecting the edges of the latter, while the sides without any strips abut against the strips of adjacent plates.
  • the assembly is all fixed to the wall by means of bolts. This type of fixture has several drawbacks.
  • the first drawback lies in that, while the strips overlap with the juxtaposed edges of adjacent plates, thereby eliminating a potential weakness zone in the system, there are no elements overlapping the points at which four adjacent plates converge, which thus constitute a potential weakness zone of the system, because a bullet hitting one of said points would meet with a lower resistance to penetration.
  • a second drawback lies in the fact that different configurations of the plates and of the corresponding strips are needed, depending on the point on the wall to which they are attached, particularly in line with the corners forming the joints between consecutive walls.
  • the present invention overcomes the above-described drawbacks by means of a fixing system according to claim 1 , of the type entailing the use of armor in the form of plates, arranged so as to cover the whole surface to be protected, the junction lines between said plates being surmounted by strips of ballistic steel, or other similar material, with means suitable for attaching said plates and said strips to the surfaces to protect, and characterized in that there are further tabs that overlap the junction lines between said strips so as to eliminate the weakness zones represented by the vertexes of said plates, where the corresponding strips come together.
  • the invention eliminates the weakness zones, represented by the point where four adjacent plates converge, by means of tabs overlapping the joint between the strips that converge on the same point.
  • the invention also concerns several particular shapes of strip and tab for the assembly of the armor plates in line with the corners of the shelter and with the vertexes of the shelter, i.e. with the points where two consecutive walls and the roof converge.
  • the invention is completed with several fixing means that enable its effective attachment to the walls, reducing the vibrations generated when the shelter is in transit with the armor plating already assembled.
  • the main advantage of the fixing system according to the invention lies in that all the weakness zones are completely eliminated, with a considerable improvement in the protection of the installation.
  • the fixing system according to the invention enables a marked reduction in the number of different parts needed, with an advantage both for the costs and, above all, for the ease of management of the parts concerned, that (it is important to bear in mind) are preferably assembled at the site where the system is installed.

  • figure 4 shows the sequence of steps for fixing the armor plates to the surface to be protected
  • figure 5 shows several shapes of strip and tab for use in areas where two or more surfaces converge.
  • Fig. 2 shows several plates (2), the adjacent edges of which are surmounted by strips (4) of ballistic steel, or other similar material, so as to eliminate any potential line of weakness, since a bullet exactly hitting the juxtaposed edges of two adjacent plates (2) would have a high probability of passing through the barrier created by said plates.
  • the strips (4) effectively protect the edges of the plates (2), they leave the vertexes (5) of the plates at least partially unprotected, because in line with said vertexes (5), there is the point where the four underlying strips (4) come together.
  • Said fixing means (3) substantially comprise a stud bolt (7) that is screwed into a suitably threaded seat (8) prepared in the wall or roof of the shelter
  • the structure of the walls and roof of the shelter (1 ) determines the way in which the threaded seat (8) is prepared.
  • said threaded seat may, for instance, consist of a metal element inserted in the thickness of the wall or roof and fixed to the bottom thereof by means of glue (8a) and an injection of resin (8b).
  • Said shaped nut (9) is screwed onto the stud bolt (7) so that it can be tightened thereon, leaving a certain amount of clearance between the elements being fixed together, i.e. the plate (2), the strip (4) and the tab (6), said clearance being taken up by seals made of rubber, or other similar material, inserted between the elements in contact with one another.

  • a second seal (10a) is inserted between the surface of the shelter (1 ) and a strip (4)
  • a third seal (11 ) is inserted between a nut (9) and a plate (2).

  • the nut (9) comprises a cylindrical portion (9a) that is threaded internally so as to be screwed onto the corresponding thread of the stud bolt (7), said cylindrical portion (9a) having the same diameter as the unthreaded central part (7a) of the stud bolt (7).
  • said cylindrical stretch must be long enough to leave the necessary clearance between the plates (2), strips (4) and tabs (6) in order to ensure the correct locking of the parts after the insertion of said seals (10), (10a) and (11 ).
  • Figures 4 (a, b, c, d) show the sequence of steps for installing the components of the ballistic protection system according to the invention.
  • Said threaded seats (8) (fig. 4a) into which the corresponding stud bolts (7) are screwed are first prepared in suitable positions on the surfaces to protect.
  • the positioning of the strips (4) is facilitated by the particular shaping of the ends of the strips, which makes it easy to temporarily position them between two adjacent rubber bushings (12).
  • the two ends of each strip (4) have portions (13) shaped so that they interface with the bushings (12), e.g. an arc of a circle with a radius that is the same as the outer radius of the bushings (12).
  • the distance d between the two portions (13) located on the same end of each strip (4) is such that the strip can fit between two bushings (12) under the effect of a slight pressure, so it then remains substantially in its established position. This facilitates the assembly procedure because the strips (4) remain in place even if the plates
  • the whole system comprises a limited number of different parts.
  • the different component parts would be limited to six, i.e. one plate (2), two strips (4, 4a) and three tabs (6, 6a, 6b), in addition to the normal metal parts and seals, of course.
  • the invention has been described herein as a non-limiting example of a preferred embodiment. A person skilled in the art may find numerous other embodiments, all coming within the scope of the invention according to the following claims.
