Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double glazing for crime prevention which prevents an outside intruder for criminal acts from easily entering a building. Further, the present invention relates to a double glazing having both a security effect, heat insulation, and soundproof performance.

[0002]

2. Description of the Related Art In a building, a door and a window for daylighting are opposed to a pair of glass, a laminated glass in which a pair of glass is adhered by an intermediate film such as polyvinyl butyral, a transparent resin plate, and a pair of transparent plate members facing each other. A spacer is arranged at the peripheral edge of the surface, and is provided using a double-layer glass or the like formed by bonding.

An outside intruder for the purpose of criminal acts such as theft and robbery usually enters a building by destroying an entrance such as a door using glass or a transparent resin plate, a window for lighting, and the like. As the invasion method, it is considered that the glass is broken, a part of the glass is broken, or a hole is made in a transparent resin plate to unlock or break a lock provided on a door or a window.

[0004] Compared to a raw glass veneer that has not been subjected to a strengthening treatment to prevent cracking after being manufactured by the float method, it is heated and cooled after the float method is manufactured, or a portion of sodium in the glass is removed. Even if the glass is broken even if the glass is broken, tempered glass that has been made hard to break by generating stress on the glass surface by chemical treatment such as substitution with potassium, or a pair of glass bonded together with an interlayer such as polyvinyl butyral Laminated glass with less holes and less holes in cracked parts has higher crime prevention.

[0005] Further, regarding the destruction of the entrance, a laminated glass made of tempered glass and a polycarbonate plate which is a hard-to-break resin are used, or polyethylene terephthalate or the like is used so that even if the glass is broken, it cannot enter. Security glass in which a transparent resin sheet is adhered to glass has been devised. Security glass such as meshed glass that is difficult to make holes easily, laminated glass with a laminated structure of five or more layers of glass and polyvinyl butyral, laminated body of glass and polycarbonate, and laminated body of glass and polyethylene terephthalate. Has also been devised.

In recent years, double-glazing is often used for windows for daylighting in general houses and office buildings for heat insulation and soundproofing. The double glazing requires more time to break than single glazing because there are two or more glasses, but the double glazing using a pair of single glass glazing can be easily broken.

[0007] For security, at least one of the double-glazed glass may be a netted glass. However, since the double-glazed glass has a heat insulating function, cracks are likely to occur due to a change in temperature when the double-glazed glass is meshed. Had disadvantages.

Therefore, in order to prevent crime, it is conceivable to use the above-mentioned security glass for the double-glazed glass so that the glass is hard to be broken by an external intruder hit by a metal hammer or the like, and the security effect is further enhanced. .

[0009] However, in order to prevent a crime aimed at a jewelry store, a jewelry store, a financial store, a safe inside a building, and the like using the security glass, any of the above-mentioned security glasses is protected from outside intruders. Prepare multiple intrusion instruments such as metal hammer, crowbar, glass cutter, cutter knife, electric drill, etc.
If you are more proficient in how to break security glass,
Even if any of the aforementioned security glass is used for a door, a window, or the like, it can be broken and can be used as an entrance.

As a means for further improving the security effect, a method of physiologically threatening an external intruder is disclosed in Japanese Patent Application Laid-Open No. Hei 10-266717 by interposing a plurality of glass plates opposed to each other with a spacer interposed therebetween. Sealing with a sealant, in a double glazing in which an intermediate layer is formed between opposing glass plates, the intermediate layer, i.e., the interior space of the double glazing structure is stimulated to give a sense of discomfort to the intruder temporarily, Alternatively, a double glazing filled with a gas that paralyzes an intruder is disclosed.

[0011]

Problems to be Solved by the Invention
The double-glazed glass disclosed in No. 17 is manufactured by a float method, and then, when using only a raw glass single plate that has not been subjected to a tempering treatment to prevent cracking, the double-glazed glass is made of a metal hammer, When an external intruder is destroyed using a destruction means such as a crowbar, the threatening gas leaks into the building, that is, into the room, so if there is a person inside the room, the person inside the building also inhales. There was a possibility. That is, there is a problem that the action of the resident or the like is suppressed by inhaling the gas for intimidation, and it is impossible to counter the outside intruder or escape from the outside intruder immediately.

For this purpose, three or more sheets of glass which are arranged opposite to the double-glazed glass are used, the internal space of the double-glazed glass structure is made two or more layers, and an outside intruder breaks or punches a hole in the double-glazed glass from outside. Although it is also described that the gas is prevented from diffusing to the indoor side when the glass is laminated, the laminated glass having a laminated structure with two or more internal spaces is composed of a laminated glass in which two glass sheets are opposed to each other. Is complicated and time-consuming to manufacture. In addition, double-glazed glass with three or more single sheets of raw glass and two or more internal spaces, all of the glass used when an external intruder strikes with a penetrating instrument such as a metal hammer or a crowbar is used once. Cracks are easily imagined and cannot prevent occupants from inhaling gas.

Japanese Patent Application Laid-Open No. H10-266717 discloses a glass sheet other than a single sheet of raw glass, a glass sheet having a film laminated on its surface, a glass sheet subjected to a tempering treatment, and a plurality of glass sheets. It is described that various types such as a laminated glass plate bonded through an intermediate film such as a film can be used, and further, as a glass plate, a transparent resin plate called an organic glass and a laminate of a normal glass plate and a transparent resin plate Although it is stated that it is also possible to use, it is possible to enhance the security effect of the double-glazed glass and prevent the indoor resident from inhaling gas. Is not taken into account.

A gas which provides a security effect to the double glazing;
That is, it does not describe the specific types of gas that threatens an external intruder, the pressure of the gas sealed in the internal space of the double-glazed structure, and the heat insulation and soundproofing functions that are inherent functions of the double-glazed glass.

[0015]

DISCLOSURE OF THE INVENTION The present invention has been made to solve the above problems, and has a security effect, that is, a gas that threatens an external intruder is enclosed in an inner space of a multi-layer glass structure. By using a transparent resin plate, a laminate made of transparent resin of different materials, or a laminate of glass and transparent resin on the indoor side surface of the multi-layer glass structure, it is possible to prevent inhalation of gas by occupants in the room and further effect An object of the present invention is to provide a combination of facing transparent plate-shaped members having a double-layered glass structure that can obtain an effective security effect.

Further, according to the present invention, when an external intruder for criminal purposes makes a hole in the double-glazed glass, the external intruder is immediately enclosed in the internal space of the double-glazed glass for inhaling the gas. It provides a suitable internal pressure of the gas.

Further, the present invention provides a security effect and heat insulation, and / or
Another object of the present invention is to provide a double glazing having both soundproof performance.

The present invention relates to a double-glazed glass formed by disposing a spacer on the peripheral edge of a pair of transparent plates facing each other, bonding the spacers together, and then sealing with a sealing material. Mercaptans, ethers,
Thioethers, halogenated thioethers, halogenated ketones, halogenated nitro compounds, halogenated aromatics, nitrogen oxides, or ammonia are enclosed at an internal pressure of not less than 1.01325 bar and not more than 1.5 bar. The multi-layer glass structure has a transparent plate on the indoor side as a transparent resin veneer, a laminate composed of transparent resins of different materials, or a laminate of glass and transparent resin, which has a security effect. It is a layer glass.

Further, the present invention is a double-glazed glass formed by disposing a spacer on a peripheral edge portion of a pair of transparent plate bodies facing each other, bonding the spacers, and then sealing them with a sealing material.
In addition to mercaptans, ethers, thioethers, halogenated thioethers, halogenated ketones, halogenated nitro compounds, halogenated aromatics, nitrogen oxides, or ammonia in the internal space of the multilayer glass structure, A gas having a heat insulating and / or soundproofing effect is sealed at an internal pressure of 1.01325 bar or more and 1.5 bar or less. A laminated glass having a security effect characterized in that it is a laminated body made of a resin or a laminated body of glass and a transparent resin.

Further, according to the present invention, the gas for obtaining the heat insulating and / or soundproofing effect is air, nitrogen, hydrogen, helium,
The double-glazed glass according to the above, wherein the glass is neon, argon, krypton, xenon, or sulfur hexafluoride.

Further, the present invention is the above-mentioned double-glazed glass characterized in that at least one surface of a transparent plate used for the double-glazed glass is coated with Ag, SnO ₂ , ITO or TiO ₂ .

By using the double glass of the present invention in which the inside of the building, that is, the inside of the building, is a transparent resin, a laminate of transparent resins of different materials, or a laminate of glass and transparent resin, an outside intruder can use a metal. When the double-glazed glass is impacted with a hammer, crowbar, or other intrusion device, the glass on the indoor side is less likely to break and the gas that threatens an external intruder is suppressed from leaking into the room, and the indoor The probability that the resident will inhale the gas is lower than when a single glass plate is used inside the room.

As the transparent plate used for the indoor side of the double-glazed glass of the present invention, that is, for preventing the gas from leaking into the indoor side, there is a transparent resin plate which is hardly broken even when subjected to an impact. A single layer of transparent resin such as a vinyl plate, a polycarbonate plate which is used as a bulletproof glass and has a rigid main chain containing a benzene ring in the main chain in the molecular structure, or a laminate made of transparent resin of different materials The body can be used.

Usually, the thickness of the transparent plate used for the double glazing is 3 mm to 12 mm. In order for the transparent resin veneer used on the indoor side of the double-glazed glass of the present invention not to be easily broken by an external intruder hit by a metal hammer or the like, the acrylic plate and the vinyl chloride plate preferably have a thickness of 4 mm or more. The thickness of the polycarbonate plate is preferably 3 mm or more. It goes without saying that the thicker the transparent resin plate used on the indoor side of the double-glazed glass of the present invention, the harder it is to break and harder to break due to the impact of an external intruder with a metal hammer, crowbar or the like.

[0025] An external intruder intrudes the double-glazed glass with a metal hammer,
An elastic polyvinyl butyral resin is one that is less likely to open a hole when subjected to an impact with a bar or the like, and can be used as an interlayer film of a laminated body of glass and resin used on the indoor side of the double glazing of the present invention. Further, when an external intruder gives an impact to the double-glazed glass with a metal hammer, a crowbar, or the like, there is a so-called PET sheet made of polyethylene terephthalate as a material that is difficult to make a hole, and the PET sheet may be adhered from the indoor side. Alternatively, it may be a laminate of a PET sheet and a transparent plate, and can be used on the indoor side of the double-glazed glass of the present invention.

Further, in the transparent plate-like body on the indoor side of the double-glazed glass of the present invention, the above-mentioned acrylic plate, vinyl chloride plate, polycarbonate plate or the like may be laminated with glass. Since a laminated body of glass and a transparent resin plate has a laminated structure to obtain strength, the transparent resin plate may be a thin sheet.

The transparent plate used for the outdoor side of the present invention is a single sheet of raw glass, tempered glass, a glass plate having a film adhered to the surface, a tempered glass, and a plurality of glass plates interposed by an intermediate film such as a film. A laminated glass, a transparent resin plate, a laminated body of glass and a transparent resin, or the like can be used.

Gases that threaten an external intruder enclosed in the inner space of the double-glazed glass of the present invention and enhance the crime prevention effect include irritant gases, so-called suffocating, sneezing and tear-forming gases, and hypnotic, There is a laughing gas, that is, as a kind of gas, the inner space of the double-glazed glass of the present invention is a mercaptan, ether, thioether, halogenated thioether, halogenated ketone, halogenated nitro compound, halogenated gas. Aromatics, nitrogen oxides, or ammonia can be encapsulated.

In the double-glazed glass of the present invention, the pressure of the gas sealed in the inner space of the double-glazed glass structure is at least atmospheric pressure (1.0 atm) at room temperature, that is, 25 ° C., ie, 1.01325 bar or more. It can be set to 5 bar or less.

When glass is used as a single glass plate or a laminate for a pair of transparent plates facing the double-glazed glass of the present invention, the pressure of the gas in the internal space of the double-glazed structure is preferably room temperature, ie, Above atmospheric pressure at 25 ° C.,
It is not less than 01325 bar and not more than 1.2 bar.

When only a transparent resin plate such as an acrylic resin, a vinyl chloride resin, and a polycarbonate resin is used as a pair of transparent plates facing the double-glazed glass of the present invention, the internal space of the double-glazed glass structure is used. Gas pressure is preferably room temperature,
That is, at 25 ° C., at least 1.05 bar and 1.5 bar
It is as follows.

The pair of transparent plates facing each other is swelled outward when the pressure of the gas in the internal space becomes higher than the atmospheric pressure outside the multilayer glass, so that one transparent plate is formed. When the plate thickness is about 3 mm, the gas pressure is 1.2
It is preferably below bar.

In particular, after being manufactured by the float method, the raw sheet glass that has not been subjected to a tempering treatment to make it hard to break is pressed from the inside of the glass by the pressure of the gas sealed in the internal space of the double-layer glass structure. Particularly, when the gas pressure is increased, cracks may occur.
In the case of using a laminated sheet of raw glass single plate, raw glass and transparent resin for a pair of transparent plates facing each other of the double-glazed glass,
Even if the raw glass used is thick, the temperature of the gas rises due to the increase in solar radiation and the outside air temperature, and the pressure of the gas sealed in the inner space of the multi-layer glass may increase, which may cause cracks. is there. Therefore, it is preferable that the pressure of the gas in the internal space of the double glazing structure when using raw glass is 1.2 bar or less at room temperature, that is, 25 ° C.

When a single sheet of raw glass is used on the outside of a pair of transparent plates facing the double-glazed glass of the present invention, an outside intruder hits it with a metal hammer, a crowbar, or the like, so that the outside of the living room is hit. Since the flat glass sheet is easily broken and the gas sealed in the inner space of the double-glazed glass is immediately diffused to the outside, the pressure of the gas does not need to be so high, but may be about atmospheric pressure. Even when a single reinforced glass sheet is used outside the pair of transparent plate bodies facing the double glazing of the present invention, when an external intruder breaks the tempered glass by hitting with a metal hammer, a crowbar, etc. Since the gas sealed in the internal space of the glass is immediately diffused to the outside, the pressure of the gas does not need to be so high, but may be about atmospheric pressure.

If the material of the transparent plate on the outdoor side of the pair of transparent plates facing the double-glazed glass is only a transparent resin such as an acrylic resin, a vinyl chloride resin or a polycarbonate resin, an outside intruder may be a metal. Although the transparent resin plate is not easily broken even when hit with a hammer, crowbar, etc., it is conceivable that an external intruder pierces the outer transparent resin plate by using an electric drill etc. . By setting the pressure of the gas sealed in the interior space of the double-glazed structure to be more positive than the atmospheric pressure, when an outside intruder makes a hole in the transparent resin plate outside the double-glazed structure, the outside of the building is burglar-proof. The gas that enhances the effect diffuses immediately, making it easier for outside intruders to inhale the gas.

When the pressure of the gas sealed in the inner space of the double-glazed glass structure is 1.05 bar or more, the gas is immediately released when an outside intruder pierces the transparent resin plate on the outside of the double-glazed glass. Since the outside intruder that is scattered outside the building and near the hole inhales the gas that enhances the security effect of the high concentration, the security effect can be further expected.

When only a transparent resin is used both on the outside and the inside of the room as a pair of transparent plate bodies facing each other of the double-glazed glass,
By increasing the thickness of the transparent resin plate both on the outside and the inside of the room, even if the pressure of the gas in the internal space is high, the multi-layer glass does not easily expand, so that when the intruder breaks the multi-layer glass, The amount of gas that enhances the security effect can be increased.
If the material of the transparent plate is only a transparent resin, the thickness of both transparent plates is increased to 1.5 bar by increasing the gas pressure.
r.

When the pressure of the gas sealed in the internal space of the double-glazed structure is higher than 1.5 bar, the gas is heated by the sunshine during the day and the temperature of the gas in the internal space becomes high. There is a possibility that the transparent resin is deformed with the passage of time due to a change in internal pressure due to a decrease in temperature.

When a gas that enhances the security effect of the double glazing is used alone, the necessary amount of gas is used in consideration of the effect on the human body when inhaled by an external intruder. In some cases, the pressure in the internal space of the double glazing is reduced relative to the atmospheric pressure. When the pressure is reduced, the double-glazed glass may be dented inward, and when raw glass is used for the double-glazed glass as in the case of pressurization, the glass may be cracked. Therefore, it is preferable that the internal space of the double glazing of the present invention is not depressurized with respect to the external pressure.

When the internal space of the double glazing is decompressed only by the gas that enhances the security effect, the gas that provides the security effect to the double glazing is mixed with a gas that has heat insulation and / or soundproofing effects. For example, it is better to dilute the gas that gives the security effect to the insulating glass and / or dilute it to a gas that has a soundproofing effect, and to seal it in the internal space of the insulating glass of the present invention at atmospheric pressure and slightly more pressurized than atmospheric pressure. It is simple in terms of construction, and can provide the double-glazed glass of the present invention with a heat insulating and / or soundproofing effect.

The gas for obtaining the heat insulation and / or soundproofing effect sealed in the inner space of the double-glazed glass of the present invention includes:
Air and nitrogen can be used because they are inexpensive and have low thermal conductivity, but in order to further improve the soundproofing effect, hydrogen, helium, neon, argon, krypton, xenon, or 6-fluorine, which has a different sound propagation speed from air. Sulfur chloride can be used.

When the inner space is air, the air acts as a spring and causes resonance at a specific frequency in the low frequency range,
It is known that the sound insulation performance is reduced, but the sound insulation performance can be improved by enclosing the gas in the internal space.

For the heat insulation effect, it is preferable to enclose a gas having a lower thermal conductivity than air alone in the inner space of the double-glazed glass since the heat transmission coefficient becomes small.

The transparent plate used in the double-glazing of the present invention has silver having a low emissivity of infrared light, ie, Ag, tin oxide, ie, SnO ₂ , indium tin oxide (In).
When coated with Dn Tin Oxide, that is, ITO or titanium oxide, that is, TiO ₂ , not only the heat insulating effect can be further improved but also the heat shielding effect can be exerted. Alternatively, it is preferable to coat at least one surface of the transparent plate on the outdoor side, preferably on one surface on the indoor side, with Ag, SnO ₂ , ITO, or TiO ₂ .

[0045]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a double-glazed glass 1 of the present invention has a spacer 4 disposed on the opposing peripheral portions of transparent plate-shaped bodies 2 and 2 'facing each other. A gas that gives a security effect to the double glazing or a gas that gives a security effect to the double glazing in the internal space 3 of the double glazing which is fixed with the spacer 4 to the transparent plate-like bodies 2 and 2 ′ and sealed by the sealing material 6. And / or a gas mixture having a soundproofing effect.

The transparent plate-like body 2 on the indoor side is formed by sticking a transparent resin plate such as a polycarbonate plate, an acrylic plate, a vinyl chloride plate or the like, a laminate composed of transparent resins of different materials, and a PET sheet to glass or transparent resin. A transparent plate or a laminate of glass and a polycarbonate plate, an acrylic plate, a vinyl chloride plate, polyvinyl butyral, a PET sheet, or the like can be used. The glass part of the laminated body of glass and transparent resin plate may be either raw plate glass or tempered glass. It goes without saying that no single glass plate is used on the indoor side.

The transparent plate-shaped body 2 'on the outdoor side is made of a single sheet of raw glass, tempered glass, a glass plate having a film adhered to its surface, and a plurality of glass plates joined via an intermediate film such as a film. Laminated glass or a laminate of a transparent resin plate and glass can be used.

For the purpose of dimming, the transparent plate body on the indoor side and the transparent plate body on the outdoor side are both colored by a so-called sunshade, or they are colored by a colored coat film. It does not matter. That is, a colored transparent resin plate, ultraviolet and infrared absorbing glass, dark gray glass, green glass, or the like can be used.

The types of gas for imparting a security effect to the double glazing enclosed in the internal space 3 of the double glazing 1 of the present invention include mercaptans, ethers, thioethers, halogenated thioethers, and halogenated ketones. , Halogenated nitro compounds, halogenated aromatics, nitrogen oxides, or ammonia.

Air, nitrogen, hydrogen, helium, neon, argon, and the like as the types of gas that have a heat insulating and / or soundproof effect sealed in the internal space 3 of the double-glazed glass 1 of the present invention.
Krypton, xenon, or sulfur hexafluoride.

At least one surface of the transparent plate used for the double-glazed glass 1 of the present invention, preferably one surface
It is preferable to coat g, SnO ₂ , ITO, or TiO ₂ , because the coating further improves the heat insulating effect as well as the heat shielding effect.

The internal space 3 can be maintained in a dry state by providing a desiccant 7 in the spacer 4 and forming a hole or a slit in the spacer 4 so as to communicate with the internal space 3. It is preferable that the spacer 4 is provided inside the spacer 4 in order to prevent dew condensation and the like. If there is no desiccant 7 that adsorbs and removes the water in the internal space, the water in the internal space may not be removed, and the dew point performance may decrease.

The double-glazed glass of the present invention includes a spacer 4 made of aluminum, duralumin, resin or the like, an adhesive layer 5 made of an organic polymer adhesive or a double-sided tape made of butyl rubber, a polysulfide-based, silicon-based, or soft Materials that are usually used for manufacturing a double-glazed glass, such as a sealing material 6 made of vinyl chloride or the like, can be used. However, since a gas having a security effect is sealed in the internal space, there is no gas leakage. It goes without saying that it is important. Therefore, it is preferable to use, as the sealing material 6, a material that is used in the internal space and has a security effect that does not allow gas to permeate as much as possible.
The outside of the sealing material 6 may be further sealed with a sealing tape made of metal foil or the like. By arranging the spacer 4 and the sealing material 6 around the entire periphery of the double-glazed glass 1, the hermeticity of the internal space of the double-glazed structure can be maximized.

In a hard and elastic material such as glass, not only does sound permeate, but the natural vibration of the material and the frequency of a specific sound may overlap, so that the sound may be more easily transmitted. This is called a coincidence effect. In glass, although it depends on the thickness, it is 1000 to 400.
It is easy to occur in the high range of 0HZ. Also, the reduction in sound insulation performance in the low-tone range, which is a common feature of double-glazed glass, increases as the thickness of the pair of transparent plates facing each other is the same. In order to suppress the decrease in sound insulation performance due to the coincidence effect in such a high-temperature region and the decrease in sound insulation performance due to the resonance transmission phenomenon in a low-temperature region, the thickness of a pair of transparent plate-shaped members facing each other in the multilayer glass structure is required. Preferably have different thicknesses. In the double glazing of the present invention, in addition to filling a gas having a soundproofing effect into the internal space of the double glazing structure, the thickness of the pair of transparent plates facing each other in the double glazing structure is made to have a different thickness. By doing so, further improvement in sound insulation performance can be expected.

100% concentration ₂ COC ₆ H _5, and sealed with 1.1 bar. When the double-glazed glass was attached to a predetermined window position in the field and hit with a metal hammer from the outdoor side, the raw sheet glass 8 on the outdoor side was broken, and chloroacetophenone was radiated to the atmosphere over several meters around, and Caused severe tearing by the gas and was temporarily hampered. The polycarbonate 9 on the indoor side was not destroyed. Example 2 As shown in FIG. 3, a double-glazed glass sheet 10 having a thickness of 3 mm was placed outside the room, and a raw glass sheet 11 having a thickness 3 mm was placed inside the room.
And a PET sheet 12 having a thickness of 0.5 mm and a polycarbonate 13 having a thickness of 2 mm are produced using a transparent laminate which is bonded with an adhesive, and chloroacetophenone, which is a halogenated ketone, is contained in the internal space 3 of the double-glazed glass, that is, CICH
100% concentration ₂ COC ₆ H _5, and sealed with 1.1 bar. When the double-glazed glass was attached to a predetermined window position outdoors and hit with a metal hammer from the outside, the raw sheet glass 10 on the outside was destroyed, and chloroacetophenone was radiated into the atmosphere over a few meters around, and Caused severe tearing by the gas and was temporarily hampered. The laminate consisting of the glass 11, PET sheet 12, and polycarbonate 13 on the indoor side had cracks in the glass portion 11, but was not broken.

[0056]

According to the present invention, when a gas is sealed in the inner space of the multilayer glass structure, a gas which gives a security effect to the multilayer glass, for example, a stimulating, hypnotic, or laughing gas is used alone or with another gas. By using it in a mixture, when an outside intruder for theft, robbery, etc. breaks or punctures the outdoor glass of the double-glazed glass of the present invention, the intruder may be choked, sneezed, crying, Hypnosis, laughter, etc. are temporarily generated, threaten external intruders, hesitate to act, and prevent subsequent criminal acts.

By forming the transparent plate body on the indoor side of the double-glazed glass structure into a transparent resin plate, a laminate made of transparent resin of different materials, or a laminate of glass and transparent resin, an outside intruder can use a metal hammer, When the double glazing of the present invention is banged or damaged from the outdoor side using an intrusion instrument such as a crowbar or an electric drill, there is a possibility that the transparent plate body on the indoor side may be broken. As compared with the case, the gas is prevented from leaking to the indoor side, and when a resident is present on the indoor side, the possibility that the resident on the indoor side inhales is reduced. By letting outside intruders aiming at robbery inhale gas that gives the double glazing the security effect, for example, hesitate the action of outside intruders, and allow time for indoor residents to escape, or for police, security companies, etc. You can earn time to report.

Further, when a crime prevention device such as an alarm device or a notification device is activated, an outside intruder inhales gas which gives a security effect to the double-glazed glass, and the person cannot be stuck and may be immediately arrested. Yes, the security effect is significantly improved.

By setting the pressure of the gas to be sealed in the inner space of the double-glazed structure to be equal to or higher than the atmospheric pressure, the gas which threatens the external intruder and gives the double-glazed effect to the double-glazed glass is removed by the external intruder. When the transparent plate-like body on the outdoor side of the laminated glass is crushed or pierced, it is immediately radiated to the outdoor side, and an external intruder inhales the gas, so that the double-glazed glass can exhibit the security effect.

In addition to the gas that threatens an external intruder and gives the double glazing a crime-preventing effect, a gas having heat insulation and / or soundproofing properties inherent in the double glazing is enclosed in the interior space of the double glazing structure. In addition to the security effect,
