Description

Technology Field

[0001] The present invention relates to wired glass plates, and more specifically, to wired glass plates in which a wire mesh is inserted between glass plates joined together. Background Technology

[0002] Plate glass, commonly used in windows, doorways, or soundproof walls, is brittle and can easily shatter even from a weak impact. When this ordinary plate glass breaks, glass fragments scatter, posing a safety risk.

[0003] To address this, wired glass, which is laminated by inserting a wire mesh between glass panels to compensate for their brittleness, is becoming widely used. This type of glass is frequently used in display cabinets and interior doors for various applications; the internally inserted wire mesh reinforces the glass's strength, minimizes the scattering of glass fragments by keeping the glass suspended within the mesh upon breakage, and provides a decorative effect through the unique shape of the mesh.

[0004] Patent Registration No. 2169083 (Kim Yun-hee) of the Korean Intellectual Property Office relates to the aforementioned wired plate glass, comprising: a first glass having a first inner adhesive member formed along the edge on its upper surface; a second glass having a second inner adhesive member formed along the edge on its lower surface; and a wire mesh installed between the first glass and the second glass, with one side attached to the first inner adhesive member and the other side attached to the second inner adhesive member. The invention is characterized by comprising a binder provided between the second glass, the wire mesh, and the first glass, wherein the first inner adhesive member is interposed between the first glass and the wire mesh to form a certain gap between the first glass and the wire mesh, and the second inner adhesive member is interposed between the second glass and the wire mesh to form a certain gap between the second glass and the wire mesh, thereby forming a binder injection space inside the first inner adhesive member and inside the second inner adhesive member so as to prevent the binder from flowing out to the outside, and a cured layer is formed by injecting the binder into the binder injection space and then curing it.

[0005] This conventional technology has the advantage of not only increasing the strength of the glass by inserting a wire mesh between the first and second glass, but also preventing glass fragments from scattering upon breakage due to impact. Furthermore, by inserting and fixing the wire mesh between the first and second glass using an adhesive and a binder, the process can be carried out without special processing equipment, which lowers production costs and enables rapid production due to the relatively simple process.

[0006] Meanwhile, Patent Registration No. 1611227 of the Korean Intellectual Property Office (Daekwang Special Glass Industry) relates to a method for manufacturing the aforementioned wired plate glass, comprising: a setting step of preparing a base member by laminating in the order of a first glass layer - a first bonding layer - a wire layer - a second bonding layer - a second glass layer; a first bonding step of heating the base member while applying pressure; a second bonding step of heating in a vacuum state; and a cooling step.

[0007] This conventional technology makes it possible to apply different colors and transparency to the first glass layer and the second glass layer, thereby enabling different visual effects when viewed from the inside and outside using a single wired glass. Furthermore, since the first and second glass layers and the bonding layer are bonded together, even if the glass is broken by impact, the fragments do not scatter but remain attached to the bonding layer. Additionally, by simultaneously providing a wire layer and a bonding layer, durability and safety are dramatically improved. It has a completely different structure from conventional wired glass, offers higher durability and stability, and has the advantage of enabling the localization of wired glass due to a simple and low-cost manufacturing process.

[0008] However, while the aforementioned conventional technologies can enhance the strength of the glass and suppress the scattering of glass fragments using wire mesh, the wire mesh must be inserted between the glass panes; furthermore, if glass panes with excessively fine wire mesh are used as sound barriers, birds often collide with the sound barrier because they fail to recognize the mesh.

[0010] The present invention was created to solve the aforementioned problems, and its purpose is to provide a wired glass plate in which a finely formed wire mesh is inserted so that the wire mesh can be perceived as thick, particularly from the side so that the wire mesh appears thicker, and the wire mesh can be prevented from being exposed to the outside of the glass plate.

[0011] Another objective is to provide wired plate glass that can provide the same effect as wired plate glass with an inserted wire mesh, even without a wire mesh. means of solving the problem

[0012] The wired plate glass of the present invention for achieving the aforementioned purpose comprises: a first plate glass made of a transparent material; a second plate glass laminated to the first plate glass; a wire mesh inserted between the first plate glass and the second plate glass; and at least one sheet inserted between the first plate glass and the second plate glass together with the wire mesh, made of a thermosetting or thermoplastic resin made of a light-transmitting material, which softens upon heating to integrally bond the first plate glass and the second plate glass with the wire mesh inserted therein.

[0013] The above wire mesh is characterized by having a length and width that match the length and width of the first glass plate or the second glass plate, or having a length and width smaller than the length and width of the first glass plate or the second glass plate.

[0014] At least one of the first glass plate and the second glass plate further includes a grid pattern printed in a grid shape corresponding to the shape of the wire mesh on a surface facing the wire mesh.

[0015] The above grid pattern is characterized by having a length and width smaller than the length and width of the first glass plate or the second glass plate.

[0016] The above wire mesh is formed with a length and width smaller than the length and width of the first glass plate or the second glass plate, and the grid pattern is characterized by having a length and width corresponding to the length and width of the wire mesh.

[0017] The present invention further comprises at least one ring-shaped sheet having a through hole formed in the center into which the wire mesh is inserted, interposed between the first glass plate and the second glass plate, and made of a thermosetting or thermoplastic resin of a light-transmitting material that softens upon heating to integrally bond the first glass plate and the second glass plate.

[0018] The present invention further comprises an additional sheet composed of the same material as the sheet, interposed between the first glass plate and the second glass plate in a state facing the sheet with the wire mesh at the center, and softened by heating to integrally bond the first glass plate and the second glass plate with the wire mesh inserted therein.

[0019] The present invention may be configured to include: a first plate glass made of a transparent material; a second plate glass laminated to the first plate glass; a grid pattern printed in a grid shape on at least one of the first plate glass and the second plate glass; and at least one sheet inserted between the first plate glass and the second plate glass, made of a thermosetting or thermoplastic resin made of a light-transmitting material, which softens upon heating to integrally bond the first plate glass and the second plate glass. Effects of the invention

[0020] As described above, the present invention strengthens the structure by incorporating a wire mesh, and prevents the scattering of glass fragments upon breakage by binding the first glass plate and the second glass plate to the wire mesh through a hardened sheet or an additional sheet.

[0021] In addition, since the wire mesh and grid pattern form a single unit, even if the wire mesh is thin, the grid can be displayed through the grid pattern printed thicker than the wire mesh, so when used as a sound barrier, birds can easily recognize the grid. In particular, since the grid pattern is printed in the form of a flat strip, it can be easily identified even from the side.

[0022] In addition, if the wire mesh or grid pattern is formed to be smaller than the length and width of the first and second glass plates, the ends are not exposed, thereby preventing rust or corrosion and extending durability. In particular, if a ring-shaped sheet is provided, the ring-shaped sheet seals the ends of the wire mesh, completely blocking the exposure of the wire mesh.

[0023] In addition, even if the wire mesh is omitted and only a grid pattern is provided, it can provide the same effect as the grid of the wire mesh, thus preventing birds from colliding. Brief explanation of the drawing

Specific details for implementing the invention

[0025] Hereinafter, a wired plate glass according to an embodiment of the present invention will be described with reference to the attached drawings.

[0026] A wired plate glass according to an embodiment of the present invention comprises a first plate glass (11), a second plate glass (13), a wire mesh (17), and a sheet (15), as shown in FIG. 1. The first plate glass (11) and the second plate glass (13) are ordinary glass made of a transparent or translucent material, that is, ordinary plate-type glass made of a transparent material. The wire mesh (17) is composed of a metal mesh forming a grid shape. The wire mesh (17) may be made of aluminum, for example, to reduce weight.

[0027] As illustrated, the sheet (15) is inserted between the first plate glass (11) and the second plate glass (13) together with the wire mesh (17). The sheet (15) is made of a thermosetting or thermoplastic resin of a light-transmitting material. The sheet (15) may be composed, for example, of a thermosetting laminated polyvinyl butyral (PVB) film. That is, the sheet (15) is composed of a thermosetting or thermoplastic thin film.

[0028] The sheet (15) may be provided on only one side of the wire mesh (17). Alternatively, the sheet (15) may be composed of two sheets by an additional sheet (15) made of the same material as illustrated. In this case, the sheet (15) and the additional sheet (15) are provided on both sides of the wire mesh (17) with the wire mesh (17) as the center, as illustrated. That is, the sheet (15) and the additional sheet (15) are interposed between the first glass plate (11) and the second glass plate (13) in a state facing each other with the wire mesh (17) as the center.

[0029] When the sheet (15) and / or additional sheet (15) are heated inside a furnace as described below, they are softened by the heat of the furnace, and the wire mesh (17) is inserted inward. These sheets (15) and / or additional sheet (15), with the wire mesh (17) inserted due to softening, are melted by the heat of the furnace to integrally bond the first plate glass (11) and the second plate glass (13). At this time, since the sheet (15) and / or additional sheet (15) are not completely melted, the first plate glass (11) and the second plate glass (13) are integrally bonded.

[0030] Here, the aforementioned wire mesh (17) may be configured to have a length and width that match the length and width of the first glass plate (11) or the second glass plate (13), as shown in FIGS. 1 and 2. As shown in FIGS. 2 and 4, the ends of the wire mesh (17) are exposed to the ends of the first glass plate (11) and the second glass plate (13).

[0031] Meanwhile, at least one of the first plate glass (11) and the second plate glass (13) may have a grid pattern (11a) of thin film printed in a grid shape as shown in FIG. 1. The grid pattern (11a) is formed on the surface of the first plate glass (11) or the second plate glass (13) facing the wire mesh (17) as shown. The grid pattern (11a) is printed in a grid shape corresponding to the shape of the wire mesh (17) as shown in FIG. 1 and FIG. 4. The grid pattern (11a) is printed with a predetermined thickness in which dissipation is prevented by a metallic paint so that it maintains its grid shape without dissipating even with the heat of the furnace.

[0032] The grid pattern (11a) may be configured with a length and width corresponding to the length and width of the wire mesh (17) as shown in FIGS. 1 and FIGS. 4. Accordingly, the grid pattern (11a) is exposed together with the end of the wire mesh (17) at the end of the first glass plate (11) or the second glass plate (13) as shown.

[0033] In the wired glass plate (10) according to the embodiment of the present invention configured as described above, the aforementioned grid pattern (11a) is printed on the side of the first glass plate (11) as shown in FIG. 3 (S1 in FIG. 3). The first glass plate (11) is sequentially stacked with a sheet (15), a wire mesh (17), an additional sheet (15), and a second glass plate (13) as shown in FIG. 2, and then introduced into a heating furnace not shown (S2 and S3 in FIG. 3). The sheet (15) and the additional sheet (15) are softened by the heat of the heating furnace and then slightly melted. At this time, the wire mesh (17) is inserted into the sheet (15) and the additional sheet (15). The sheet (15) and the additional sheet (15) are joined together by melting to form a single body and are attached to the first glass plate (11) and the second glass plate (13).

[0034] The first plate glass (11) and the second plate glass (13) may have their surfaces slightly melted depending on the temperature of the furnace. The first plate glass (11) and the second plate glass (13) are removed from the furnace and cooled by air cooling after the sheet (15) and additional sheet (15) are melted. At this time, the sheet (15) and additional sheet (15) harden through cooling and become an integral part of the first plate glass (11) and the second plate glass (13), thereby firmly bonding them together. Therefore, the first plate glass (11) and the second plate glass (13) form a single unit even with the wire mesh (17) embedded therein, as shown in FIG. 4.

[0035] Here, the aforementioned additional sheet (15) is applied as needed. For example, the additional sheet (15) may be omitted if the thickness of the aforementioned sheet (15) is sufficient to allow the wire mesh (17) to be sufficiently inserted into the sheet (15).

[0036] Meanwhile, the grid pattern (11a) provides a grid pattern corresponding to the grid of the wire mesh (17) on one side of the wire mesh (17) as illustrated in the enlarged view in FIG. 4.

[0037] The wired glass plate (10) according to the embodiment of the present invention as described above has its strength reinforced as the wire mesh (17) is embedded as shown in FIG. 4, and the first glass plate (11) and the second glass plate (13) are bound to the wire mesh (17) by a hardened sheet (15) or an additional sheet (15), so that the scattering of glass fragments is prevented in the event of breakage.

[0038] Also, as illustrated in the enlarged view, the wire mesh (17) and the grid pattern (11a) form a single unit, so even if the wire mesh (17) is thin, the grid can be displayed through the grid pattern (11a) printed thicker than the wire mesh (17), so when used as a sound barrier, birds can easily recognize the grid. In particular, since the grid pattern (11a) is printed in the form of a flat strip, it can be easily identified from the side as well.

[0039] To explain this in more detail, the grid pattern (11a) is composed of a thickness (W2) that is thicker than the thickness (W1) of the wire constituting the wire mesh (17), as shown in the enlarged view of FIG. 4, thus providing the effect of making the wire mesh (17) appear thicker. In particular, when viewed from the side, the thickness of the wire constituting the wire mesh (17) and the thickness of the grid pattern (11a) are displayed together, making it appear even thicker. Therefore, birds can easily identify the sound barrier due to the grid pattern (11a) and the wire mesh (17).

[0040] Meanwhile, as shown in FIG. 4, the metal mesh (17) may rust or corrode as its ends are exposed to the outside. To prevent this, the mesh (17) may be configured to have a length and width smaller than the length and width of the first glass plate (11) or the second glass plate, as shown in FIG. 5. In this case, the mesh (17) may be provided with a ring-shaped sheet (15a) on its edge, as shown in FIG. 5 and FIG. 6. The ring-shaped sheet (15a) is made of the same material as the aforementioned sheet (15) as shown, and a through hole is formed in the center to allow the mesh (17) to be inserted.

[0041] A ring-shaped sheet (15a) is interposed with a wire mesh (17) between the first glass plate (11) and the second glass plate (13) as shown in FIGS. 5 and 7. When this ring-shaped sheet (15a) is introduced into a heating furnace as described above, it softens and melts together with the sheet (15) to seal the edges of the wire mesh (17) and bond the first glass plate (11) and the second glass plate (13). Thus, the wire mesh (17) is sealed by the ring-shaped sheet (15a), and as shown in FIG. 8, rust or corrosion is prevented as exposure to the outside is prevented.

[0042] As shown in FIG. 5, the grid pattern (11a) may be configured with a length and width smaller than the length or width of the wire mesh (17), or with a length and width corresponding to the wire mesh (17). That is, the grid pattern (11a) is formed with a length and width smaller than the length and width of the first glass plate (11) or the second glass plate (13). As shown in FIG. 8, the ends of this grid pattern (11a) are not exposed to the outside of the first glass plate (11) or the second glass plate (13). Therefore, the grid pattern (11a) is protected from ultraviolet rays, so deformation is suppressed.

[0043] Meanwhile, the wire mesh (17) described above may be omitted in the wire-type plate glass (10) according to an embodiment of the present invention. In this case, it is preferable that the wire-type plate glass (10) be composed of a first plate glass (11) having a grid pattern (11a) formed thereon, a sheet (15), and a second plate glass. Since the grid pattern (11a) of the wire-type plate glass (10) configured as described above displays a grid similar to the wire mesh (17), when used as a sound barrier, it can prevent birds from colliding with the grid due to the grid of the grid pattern (11a).

[0045] The aforementioned embodiments merely describe preferred embodiments of the present invention, and therefore the scope of application of the present invention is not limited thereto. Appropriate modifications (changes in structure or configuration, or partial omission or supplementation) are possible within the scope of the same concept as long as the essential features are satisfied. Furthermore, some or many of the features of the aforementioned embodiments may be combined with one another. Accordingly, since the structure and configuration of each component shown in the embodiments of the present invention can be implemented through modification or combination, it is natural that such modifications or combinations of structure and configuration fall within the scope of the appended claims of the present invention.
