Disaster prevention windows and disaster prevention films

Abstract

To provide a novel disaster prevention window.SOLUTION: The present invention relates to a disaster prevention window used in a structure in which a resin security film having glass penetration prevention performance as defined in JIS A5759: 2008 is affixed to at least a portion on at least one surface of the netted plate glass in which the metal mesh is inserted into the glass. Further, the present invention relates to a disaster prevention window used in a structure in which a resin security film having glass penetration prevention performance as defined in JIS A5759: 2008 is affixed to at least a portion on at least one surface of the netted plate glass in which the metal mesh is inserted into the glass, as well as, a resin sheet for auxiliary construction covering at least a portion of the window frame of the disaster prevention window and at least a part of the surface to which the mesh glass security film is not affixed and / or at least a part of the surface to which the mesh glass security film is affixed.SELECTED DRAWING: None

Claims

[Claim 1] (i) A window used in a structure for disaster prevention, A security film made of resin film having glass penetration prevention performance as specified in JIS A5759:2008 is affixed to at least a portion of at least one surface of a wired glass plate in which a metal mesh is inserted inside the glass. This security film forms a surface that can be accessed from the outside of the aforementioned disaster prevention window. This externally accessible surface is either the surface of the resin film itself that constitutes the security film, or the surface of a hard coat formed from UV-curable resin placed on the surface side of the resin film, as well as the surface of the window used for disaster prevention. (ii) A resin sheet for auxiliary construction to enhance protection, having a thickness of 30 μm to 2500 μm, which covers at least a portion of the window frame of the disaster prevention window described in (i) and at least a portion of the surface of the wired glass to which the security film is attached, or which covers at least a portion of the window frame of the disaster prevention window described in (i) and at least a portion of the surface of the wired glass to which the security film is attached and at least a portion of the surface of the wired glass to which the security film is not attached. A window designed for disaster prevention, including a fire-resistant window. [Claim 2] The disaster prevention window according to claim 1, wherein the security film has a margin of a certain width of 2 mm in the vertical direction from the window frame provided on the edge of the wired glass pane, or is applied to the entire surface without having such a margin. [Claim 3] The disaster prevention window according to claim 2, wherein the security film is affixed to the edge of the wired glass plate with a margin of a certain width of 2 mm perpendicular to the window frame, and a resin sheet for auxiliary installation covers the entire margin. [Claim 4] A disaster prevention window according to any one of claims 1 to 3, wherein, upon multiple vertical impacts by an impactor with kinetic energy of 120 J at an arbitrarily selected position to which a security film is attached, no penetration occurs or a hole through which a 76 mm diameter sphere can pass is not created, and when continuously exposed for 10 minutes to the pressure of a strong vertical wind with an average wind speed of 41 m / s or more and 48 m / s or less following multiple vertical impacts by the impactor, a hole through which a 76 mm diameter sphere can pass is not created. [Claim 5] A disaster prevention window according to any one of claims 1 to 4, wherein a security film is attached to both sides of a wired glass plate.
