Description

  The present invention relates to glass attached to openings such as windows and doors of buildings, and more particularly, a reinforced glass structure reinforced to enhance safety and crime prevention, a glass louver using the same, and a reinforced glass structure It relates to a manufacturing method.

  Japan has many earthquakes every year due to its geographical conditions. It is said that the glass of buildings starts to break at a seismic intensity of about 5, and not only the direct damage of the earthquake but also secondary damage such as injury due to broken glass fragments becomes a problem.

  In recent years, there have been reports of an increase in empty nests, etc., but many burglars often break windows and enter indoors. However, there are reports that the thief gives up intrusion into the building if it takes a long time to break the window glass or makes a loud noise when it breaks.

  In view of these problems, for example, a glass window reinforcing structure for a glass window described in Patent Document 1 has been proposed in order to improve safety and crime prevention. FIG. 6 shows a glass plate reinforcing structure described in Patent Document 1.

  The glass plate reinforcing structure shown in FIG. 6 includes a glass plate 51 having a flexible plastic film 53 attached to the entire indoor surface 52 of the glass plate 51, a soft material such as rubber, or a hard material such as urethane. A glass receiving member 55 having a U-shaped cross section and a window frame 54.

According to the glass plate reinforcement structure of the glass window described in Patent Document 1, the strength of the glass is increased by attaching the plastic film 53 to the glass plate 51. Moreover, even if the glass is broken, the glass can be prevented from scattering.
Japanese Patent Laid-Open No. 2004-17531

  However, in the glass plate reinforcing structure of the glass window described in Patent Document 1, the glass plate 51 to which the plastic film 53 is attached is attached to the window frame 54 via the glass receiving material 55 made of a soft material such as rubber. Therefore, when a strong impact force from the outside is applied to the glass plate 51, both the plastic film 53 attached to the glass plate 51 and the glass receiving material 55 made of a soft material such as rubber bend. Therefore, a gap is generated between the glass plate 51 and the window frame 54, and the glass plate 51 may fall off the window frame 54.

  Patent Document 1 also describes a case where the glass plate 51 with the plastic film 53 attached thereto is attached to the window frame 54 via a glass receiving material 55 made of a hard material such as urethane. Hard materials such as urethane have excellent elasticity. Therefore, similarly to the soft material such as rubber, when a strong impact force from the outside is applied to the glass plate 51, a glass film made of a plastic material 53 attached to the glass plate 51 and a hard material such as urethane. Since both of 55 are bent, a gap is generated between the glass plate 51 and the window frame 54, and the glass plate 51 may fall off the window frame 54.

  Then, an object of this invention is to provide the manufacturing method of the reinforced glass structure which prevented the drop-off | omission from a frame and improved safety | security and crime prevention, a glass louver using the same, and a reinforced glass structure.

  The reinforced glass structure of the present invention includes a reinforced glass in which a reinforcing elastic sheet is attached to the entire surface of one surface excluding the end surface of the plate glass, and a protective frame that holds the end portion of the plate glass including the elastic sheet. The protective frame is in close contact with the end face of the reinforced glass via an impact absorbing material, and is in direct contact with the surface of the reinforced glass plate glass and directly on the elastic sheet of the reinforced glass. It is characterized by biting into and closely contacting.

  The end face of the glass sheet is protected by the protective frame being in close contact with the end face of the reinforced glass via an impact absorbing material. In addition, the protective frame can directly hold the reinforcing glass by being in close contact with the surface of the reinforcing glass plate glass and directly intruding into the surface of the elastic sheet of the reinforcing glass. Since the shock absorber provided between the protective frame and the end face of the reinforcing glass absorbs vibrations repeatedly applied to the plate glass, cracks from the end face of the plate glass are prevented. In addition, since the protective frame bites directly into the surface of the elastic sheet, the elastic sheet is elastically deformed by the protective frame. Accordingly, the elastic sheet and the protective frame are always pressed against each other. Therefore, even if a strong impact force from the outside is applied, the reinforcing glass can be prevented from falling off the protective frame.

Here, the elastic sheet is desirably a polycarbonate sheet.
Since polycarbonate is excellent in impact resistance and has high mechanical strength, when used as an elastic sheet, the strength of the plate glass can be further increased. Polycarbonate is also excellent in heat resistance and weather resistance, so when a reinforced glass structure is used as a glass window in a house, etc., the polycarbonate sheet side is not only indoor but also facing the outdoor surface. The sheet does not deform or deteriorate and can continue to serve as an elastic sheet. Furthermore, since polycarbonate has high transparency, even if it is attached to the surface of a plate glass as an elastic sheet, the visibility is not deteriorated.

The impact absorbing material is preferably a silicone resin.
When a silicone resin is used as the shock absorbing material, the silicone resin absorbs vibrations repeatedly applied without transmitting to the plate glass due to its shock absorption, and can prevent cracks from the end face of the plate glass. In addition, as a property of silicone resin, it has not only the adhesion and sealing property between the reinforced glass and the protective frame, but also has a high waterproof property. Therefore, when the reinforced glass structure is used as a glass window in a house, etc., moisture Can be prevented, and a highly airtight space can be realized.

Furthermore, the protective frame is preferably made of a metal material.
By forming the protective frame from a highly rigid metal material such as aluminum or stainless steel, sufficient strength as the protective frame can be ensured. Further, when the metal is aluminum, it is lightweight and easy to process, and when it is stainless, rust due to rain or the like can be prevented.

It can also be set as a glass louver using the reinforced glass structure of this invention.
The louver's slats are constantly subjected to shocks caused by repeated opening and closing. The reinforced glass structure of the present invention can prevent cracks from the end face of the glass sheet when the protective frame is in close contact with the end face of the reinforced glass via an impact absorbing material. Moreover, the protective frame can be prevented from falling off the protective frame by directly adhering to the surface of the reinforcing glass plate glass and directly biting into and adhering to the elastic glass elastic sheet surface. When the reinforced glass structure of the present invention is used as a slat of a glass louver, it is possible to obtain a glass louver that is prevented from falling off the protective frame and has improved safety and crime prevention.

Moreover, as for the glass louver of this invention, it is desirable for a reinforced glass structure to be arrange | positioned so that an elastic sheet may become an indoor surface.
Even if the plate glass is broken or cracked, the elastic sheet itself is hardly damaged. Therefore, by setting the elastic sheet as an indoor surface, broken glass fragments are shielded by the elastic sheet on the indoor surface, so that it can be prevented from falling indoors.

  According to the glass reinforcing method of the present invention, a reinforcing elastic sheet is attached to the entire surface of one surface excluding the end surface of the plate glass to form a reinforcing glass, and a protective frame for gripping the end of the reinforcing glass including the elastic sheet is provided. It is characterized in that it is brought into close contact with the end face of the reinforced glass via an impact absorbing material, directly brought into close contact with the surface of the reinforced glass plate glass, and directly cut into the elastic sheet of the reinforced glass.

  According to the present invention, the end face of the glass sheet is protected by bringing the protective frame into close contact with the end face of the reinforcing glass via the shock absorber, and the elastic sheet of the reinforcing glass is directly attached to the surface of the reinforcing glass. The protective frame and the reinforcing glass can be firmly adhered to each other by directly biting into the surface. Therefore, even if a strong impact force from the outside is applied, it is possible to prevent the reinforcing glass from falling off the protective frame.

Here, it is good to fix to the reinforced glass by caulking a part of the protective frame.
By caulking part of the protective frame, the reinforcing glass and the protective frame can be more firmly adhered. Therefore, even if a strong impact force from the outside is applied, it is possible to prevent the reinforcing glass from falling off the protective frame.

(1) In the reinforced glass structure of the present invention, the end face of the glass sheet is protected by bringing the protective frame into close contact with the end face of the reinforced glass via an impact absorbing material. In addition, the protective frame can directly hold the reinforcing glass by being in close contact with the surface of the reinforcing glass plate glass and directly intruding into the surface of the elastic sheet of the reinforcing glass. Since the shock absorbing material provided between the protective frame and the end surface of the reinforcing glass absorbs vibrations repeatedly applied to the plate glass, cracks from the end surface of the plate glass can be prevented and the strength of the plate glass can be maintained. Furthermore, since the elastic sheet is elastically deformed by directly biting the protective frame into the surface of the elastic sheet, the elastic sheet and the protective frame are always pressed against each other. Therefore, even if a strong impact force from the outside is applied, the reinforced glass can be prevented from falling off the protective frame, and a reinforced glass structure with improved safety and crime prevention can be obtained.

(2) When a polycarbonate sheet is used as the elastic sheet, the polycarbonate has excellent impact resistance and high mechanical strength, so that the strength of the plate glass can be further increased. Polycarbonate is also excellent in heat resistance and weather resistance, so when a reinforced glass structure is used as a glass window in a house, etc., the polycarbonate sheet side is not only indoor but also facing the outdoor surface. The sheet does not deform or deteriorate and can continue to serve as an elastic sheet. Furthermore, since polycarbonate has high transparency, even if it is attached to the surface of a plate glass as an elastic sheet, the visibility is not deteriorated.

(3) When a silicone resin is used as an impact absorbing material, the silicone resin can absorb vibrations that are repeatedly applied without transmitting to the glass sheet, and can prevent cracking from the end face of the glass sheet. In addition, as a property of silicone resin, it has not only the adhesion and sealing property between the reinforced glass and the protective frame, but also has a high waterproof property. Therefore, when the reinforced glass structure is used as a glass window in a house, etc., moisture Can be prevented, and a highly airtight space can be realized.

(4) By using a metal material for the protective frame, sufficient strength as the protective frame can be ensured. Furthermore, when this metal is aluminum, it is lightweight and easy to process, and when it is stainless steel, rust caused by rain or the like can be prevented.

(5) By using a reinforced glass structure for the louver of the glass louver, the reinforced glass structure is prevented from cracking from the end face of the reinforced glass structure, which is the slat, even if it is constantly opened and closed. Can be prevented. Therefore, a glass louver with improved safety and crime prevention can be obtained.

(6) Since the reinforced glass structure of the glass louver is arranged so that the elastic sheet becomes an indoor surface, even if the plate glass is broken or cracked, the elastic sheet itself is hardly damaged. This prevents the glass fragments from falling indoors and prevents injuries caused by broken glass fragments.

(7) In the glass reinforcing method of the present invention, a reinforcing elastic sheet is attached to the entire surface of one surface excluding the end surface of the plate glass to form a reinforcing glass, and the end portion of the reinforcing glass including the elastic sheet is gripped. The end face of the glass sheet is protected by attaching the protective frame to the end face of the reinforcing glass via an impact absorber, and the end face of the reinforcing glass is directly attached to the surface of the reinforcing glass, and directly bites into the elastic sheet of the reinforcing glass. Thus, the protective frame and the reinforcing glass can be firmly adhered. The impact absorbing material prevents cracking from the glass end face, and the structure in which the elastic sheet and the protective frame press each other prevents the reinforced glass from falling off the protective frame even when a strong external impact is applied. it can.

(8) By caulking part of the protective frame, the plate glass and the protective frame can be more firmly adhered to each other. Therefore, even if a strong impact force from the outside is applied, it is possible to prevent the reinforcing glass from falling off the protective frame.

  FIG. 1 is a perspective view of a reinforced glass structure according to an embodiment of the present invention, FIG. 2 (A) is a cross-sectional view taken along the line AA in FIG. 1, and FIG. It is B line sectional drawing. FIG. 3 is a cross-sectional view showing a state in which a part of the reinforced glass structure is caulked.

  As shown in FIG. 1, a reinforced glass structure 10 according to an embodiment of the present invention includes a parting frame 1 and a reinforced glass 2 as protective frames.

  As shown in FIG. 2, the parting frame 1 is made of metal and has a U-shaped cross section formed by side pieces 1a and 1b and a central piece 1c. The width of the inner side surface where the central piece 1c is in contact with the reinforcing glass 2 is formed to be slightly smaller than the thickness of the reinforcing glass 2, and the side piece 1a of the parting frame 1 is a part of the reinforcing glass 2 when fitted into the reinforcing glass 2. It is supposed to bite into. Moreover, the parting frame 1 is made of stainless steel, so that it not only has sufficient strength as a protective frame, but also prevents rusting of the parting frame 1 due to rain or the like. However, the present invention is not limited to this, and the parting frame 1 may be made of aluminum.

  The reinforcing glass 2 is configured by adhering a polycarbonate sheet 3 as an elastic sheet to the entire surface of one surface excluding the end surface of the rectangular plate glass 4. As the plate glass 4, a plate glass with various pattern irregularities formed on one side of the plate glass, or a net-filled plate glass with a net inside the template glass for reinforcement may be used. The polycarbonate sheet 3 is obtained by forming polycarbonate, which is a thermoplastic resin having excellent impact resistance and high mechanical strength, into a sheet shape having almost the same size as the surface of the plate glass 4.

  Further, as shown in FIG. 2A, the reinforced glass structure 10 according to the embodiment of the present invention includes a silicone resin 5 as an impact absorbing material between the end surface of the reinforced glass 2 and the parting frame 1. ing. The silicone resin 5 also has a role as an adhesive, and when cured, increases the elasticity and plays a role as an impact absorbing material. The end surface of the reinforcing glass 2 and the inner surface of the center piece 1c of the parting frame 1 are closely adhered and integrated with the silicone resin 5 without any gap.

  With this structure, even if vibration is repeatedly applied to the reinforced glass structure 10, the silicone resin 5 absorbs an impact caused by the vibration, so that the impact is not transmitted to the plate glass 4. Therefore, the crack from the end surface of the plate glass 4 can be prevented.

  Moreover, as shown to FIG. 2 (B), the modified silicone resin 6 is filled in the outer peripheral surface edge part of the polycarbonate sheet 3 of the reinforced glass structure 10 concerning embodiment of this invention. Since the modified silicone resin 6 is coated on the end portion of the outer peripheral surface of the polycarbonate sheet 3, moisture is prevented from entering the end portion of the polycarbonate sheet 3.

  Next, the manufacturing method of the reinforced glass structure 10 concerning embodiment of this invention is demonstrated.

  A polycarbonate sheet 3 is adhered to the entire surface of one surface excluding the end surface of the plate glass 4 with an adhesive to obtain a reinforced glass 2. Next, the silicone resin 5 is applied to the end face of the reinforced glass 2 with a certain thickness. Immediately after that, the two side pieces 1a, 1b of the parting frame 1 are attached while pressing the end pieces of the reinforcing glass 2 so as to sandwich the end portions of the reinforcing glass 2 while pressing the two side pieces 1a, 1b outwardly. Then, the outer surface of the center piece 1 c of the parting frame 1 is lightly patted with a hammer or the like, and the parting frame 1 is brought into close contact with the end surface of the reinforcing glass 2 through the silicone resin 5.

  At this time, as shown in FIG. 2A, one side piece 1b of the parting frame 1 is in direct contact with the plate glass, and the other side piece 1a is slightly biting into and in close contact with the polycarbonate sheet 3. This is because the width of the inner side surface of the central piece 1c of the parting frame 1 is formed slightly smaller than the thickness of the reinforcing glass 2, and the polycarbonate sheet 3 is elastically deformed. With this structure, the side piece 1a of the parting frame 1 and the polycarbonate sheet 3 are in close contact with each other while always pressing each other. Therefore, the parting frame 1 can hold the reinforcing glass 2 firmly, and the reinforcing glass 2 can be prevented from falling off the parting frame 1 even if a strong external impact is applied.

  Further, as shown in FIG. 3, after the parting frame 1 is attached to the reinforced glass 2, a part of the side piece 1a that bites into the polycarbonate sheet 3 out of the both side pieces 1a and 1b of the parting frame 1 is removed. By tightening, the parting frame 1 and the reinforcing glass 2 can be adhered more firmly. Since the caulking portion 7 formed by caulking the parting frame 1 further bites into the polycarbonate sheet 3 in a convex shape, the reinforcing glass 2 is more difficult to drop off.

  Next, a glass louver using the reinforced glass structure 10 according to the embodiment of the present invention will be described with reference to FIGS. 4 and 5. 4 is a perspective view of a glass louver using the reinforced glass structure 10 according to the embodiment of the present invention, and FIG. 5 is a cross-sectional view taken along line AA of FIG.

  As shown in FIG. 4, the glass louver 30 includes an outer frame 21 and a reinforced glass structure 10 as a slat. The outer frame 21 includes a pair of vertical frame members 21a and a pair of horizontal frame members 21b. The outer frame 21 may be made of wood or metal as long as it has sufficient strength to hold the reinforced glass structure 10. On the surface where the pair of vertical frame members 21a face each other, there are provided as many attachment portions (not shown) as the number of attachments of the reinforcing glass structure 10 for holding the reinforcing glass structure 10. Further, the horizontal frame member 21b is provided with a convex portion 21c for fitting into the window frame.

  At both ends in the longitudinal direction of the reinforced glass structure 10, attachment tools (not shown) for attaching to the attachment portions of the vertical frame member 21a are provided. As shown in FIG. 5, the number of reinforced glass structures 10 to be attached is appropriately determined according to the size of the window. With the fixture, the parting frame 1 of the reinforced glass structure 10 is placed on the top, and the polycarbonate sheet 3 side is on the indoor surface. And it is attached to the attachment part of the vertical frame material 21a.

  In addition, when the glass louver 30 is closed, the reinforced glass structure 10 is arranged so that the center portion on the indoor side comes into contact with the parting frame 1 of another reinforced glass structure 10 disposed below the glass louver 30. It is installed.

  Since the rotation angle of the reinforced glass structure 10 is determined, the opening and closing thereof always involves vibration. However, in the glass louver 30 using the reinforced glass structure 10 according to the embodiment of the present invention, the silicone resin 5 is provided between the inner surface of the center piece 1 c of the parting frame 1 and the end surface of the reinforced glass 2. Therefore, since vibration generated when the glass louver 30 is opened and closed is absorbed by the silicone resin 5 without being transmitted to the plate glass 4, cracks from the end face of the plate glass 4 can be prevented.

  Moreover, since the side piece 1a of the parting frame 1 of the reinforced glass structure 10 slightly bites into and adheres to the polycarbonate sheet 3, the parting frame 1 holds the reinforced glass 2 firmly, so that it can be opened and closed. Even if a strong impact is applied, the reinforcing glass 2 does not fall off from the parting frame 1.

  Furthermore, since the polycarbonate sheet 3 side is an indoor surface, even if the parting frame 1 of another reinforcing glass structure 10 comes into strong contact with the glass louver 30 and is subjected to an impact, the plate glass 4 may break. Never do.

  In addition, even if an intruder such as a thief tries to break the glass of the glass louver 30, the reinforcing glass 2 of the reinforcing glass structure 10 of the glass louver 30 according to the embodiment of the present invention uses the polycarbonate sheet 3 as the plate glass 4. It is difficult to break because it adheres to it, and it is difficult for it to fall off from the parting frame 1, so an intruder cannot easily enter.

  The reinforced glass structure and the method for producing the reinforced glass structure of the present invention can improve the safety and security of glass, and therefore can be used for openings such as window glass and doors of buildings. The reinforced glass structure of the present invention can also be used as a louver of a glass louver.
