Description

DETAILED DESCRIPTION OF THE DRAWINGS

[0007] The architectural shielding plate object of the present invention will be described in detail on the basis of the attached schematic figures, which illustrate:

[0008] FIG. 1 is a perspective view of an architectural shielding plate according to the present invention;

[0009] FIG. 2 is a side view of the shielding plate shown in FIG. 1;

[0010] FIG. 3 is an exploded perspective view of the shielding plate shown in FIG. 1;

[0011] FIG. 4 is a view of a building assembled with the plates according to the present invention.

[0012] As shown in FIG. 1, the architectural shielding plate (10) object of the present invention is made of steel plate (11), on the back surface of which flexible elastic deformation elements (13) are installed conveniently distributed to provide balanced support for the plate (10) when installed on a vertical wall (20). Said steel plate (11) is covered by a finishing layer (12) on its front or frontal surface. Advantageously, the flexible elastic deformation elements (13) are spiral springs made from any material that provides adequate impact strength, notably to the impact of a projectile (gun bullet), deforming by compression to avoid impact on the vertical wall structure (20). The number and shape and distribution spacing of the flexible elastic deformation elements (13) on the back surface of the architectural shielding plate (10) will be established in accordance with the established shielding project. As a basic unit, it is preferred that the number of flexible elastic deformation elements (13) is at least five, distributed so that four of them are in the proximal regions of their vertices and an element in the central region of the steel plate (11). Alternatively, said flexible elastic deformation elements (13) are capsule-type pneumatic elements with compressed air.

[0013] The finishing plate 12 should be made of lightweight material and easy to handle, which can provide optimum finishing aesthetics and allow other finishing operations, such as painting application. Suitable materials for the finishing plate (12), although not limiting, are, for example, fiber blend and beneficiated gypsum or the material known commercially as drywall. It is preferred that the finishing layer (12) is in drywall, which consists of plasterboard screwed into structures of thin profiles of galvanized steel, but light and allowing installations of electrical and hydraulic components through fastening systems. In addition, a finishing layer (12) made of drywall adapts perfectly to the steel structure of the plate (10). Advantageously, the vertical wall (20) is also produced in drywall. Even more advantageously, the vertical wall (20) has the same steel plate structuring (11) covered by a finishing layer (12) on its front or frontal surface, which is preferably also produced in drywall.

[0014] The architectural shielding plates (10) can still be installed, depending on the shielding project, so as to form a double, triple shielding and so on, depending on the desired level for protection. It is preferred, however, that a single plate (10) is sufficient to provide adequate protection.

[0015] The architectural shielding plate (10) may have any thickness dimension according to the shielding project, but it is preferred that the architectural shielding plate (10) is preferably up to 3 mm thick.

[0016] Advantageously, the architectural shield plate (10) object of the present invention is structured to form a body weighing about 120 Kgf/m.sup.2 for a shielding thickness of about 7 to 12 cm.

[0017] The structuring of the architectural shielding plate object of the present invention described above, when in use and attacked by a projectile, the finishing layer (12) causes a friction in the projectile decreasing its rotation and, consequently, preventing perforation of the plate assembly (10).

[0018] FIG. 4 shows a form of structuring of a conventional wall building (Z) provided with a security system using the architectural shielding plate (10) object of the present invention at various levels of shielding, from the weakest to the strongest (A, B, C). It should be noted, however, that other levels of shielding not illustrated here may also be obtained by conjugating the number of architectural shielding plates (10).

[0019] It is further emphasized that by not propagating the fire and not changing its performance when subjected to high temperatures, the finishing layer (12) protects the steel blades (11) so that the wall/coating structure does not succumb this very adverse scenario. The same occurs in the attempt of break-in, since there is the attempt of invasion by any sharp, perforating, flammable object, etc., the combination of the malleability and self-extinguishing characteristics prevents drilling and transposition of the shielding system.

[0020] In the case of direct fire, there is also a dual performance of the components of the finishing layer (12), which should protect and maintain the static structure, ensuring its integrity for hours of direct fire resistance.

[0021] Therefore, each and every environment can be protected by the creation of a shielded security cell or the construction and shielding of its entire environment. It is also possible to apply the architectural shielding plate (10) at some place already built or under construction, where the application of the shielding will occur as a perimeter coating to the construction, creating a housing.

[0022] Once the architectural shielding plate (10) object of the present invention is applied, the persons and/or property held therein shall be protected and safe from possible shots of firearms of civilian or military use, such as fire, break-in and explosives.

[0023] In addition, it is found that the shielding plate object of the present invention is easy to transport and handle, providing rapid installation and excellent performance as structural reinforcement and resistance to high temperatures and inclement weather.
