Description

Method for manufacturing double-glazed glass and double-glazed glass manufactured thereby

[0001] The present invention relates to laminated glass, and more particularly, to a method for manufacturing laminated glass that is lightweight and capable of blocking ultraviolet rays and ultraviolet rays instead of laminated glass formed with three or more glasses, and laminated glass manufactured thereby.

[0002] To ensure comfortable living and activity conditions within buildings, humans must provide necessary heating and cooling to cope with harsh external conditions such as heat and cold. This process consumes massive amounts of energy and emits carbon dioxide. However, limited energy resources are being depleted, and the increasing carbon dioxide emissions from building heating and cooling, industry, and transportation are altering the global environment, leading to catastrophic climate change and threatening human existence. Under the global consensus that if things continue this way, humanity could perish, significant efforts are being made to reach consensus on energy conservation and environmental protection, and to implement these measures.

[0003] Improving the energy efficiency of buildings, which account for a significant portion of energy consumption, is a critical challenge for energy conservation and, through this, carbon emissions reduction. Various technologies and methods are being applied to improve building energy efficiency, such as strengthening the insulation of building envelopes and utilizing energy-efficient devices. However, windows, an essential component of buildings, remain a key area of ​​vulnerability for improving building energy efficiency due to the delay in developing new window concepts that maintain their original function, are easy to maintain, are reasonably priced, and last the life of the building. Windows, such as windows or glass-paned sash doors, typically require curtains, blinds, or verticals to block sunlight or obstruct views. However, installing curtains, blinds, or verticals on one side of a window is not only cumbersome, but depending on the building's structure, there may be insufficient space on one side of the window to hang curtains, or installing curtains or blinds on the outside of the window may be functionally inappropriate.

[0004] Addressing these issues, functional windows manufactured with double-glazed glass and incorporating roller screens or blinds were introduced. However, these conventional windows suffer from complex structures, resulting in bulky windows and thick double-glazed windows, as well as operational difficulties. Furthermore, these complex structures lead to higher costs, frequent breakdowns, and inconveniences in use.

[0005] In fact, double glazing is called this because the number of glasses used increases, and since the basic weight of glass increases with the number of glasses laminated, the weight increases.

[0006] As the weight increases, the cost of the structure supporting the glass increases, taking into account the rigidity, and accidents may occur during the process of moving it.

[0007] The present invention is an invention devised to solve the problems of the above-described prior art, and provides a double-layer glass that is lightweight but has the same heat storage efficiency and ultraviolet function as existing double-layer glass.

[0008] And in the method of manufacturing such double-glazed glass, the purpose is to provide double-glazed glass that is 33% lighter than conventional double-glazed glass and has a structure that distributes the load during the manufacturing process.

[0009] The tasks of the present invention are not limited to the tasks mentioned above, and other tasks not mentioned will be clearly understood by those skilled in the art from the description below.

[0010] In order to solve the above-mentioned problem, the technical idea of ​​the present invention is a double-layer glass in which a functional film part is arranged between glasses that face each other in parallel, and an edge of the functional film part is joined, the double-layer glass including a fixing jig part that is seated on a floor surface and has a protrusion formed on a portion thereof toward the functional film part, a support frame part that is seated on the floor surface in a state of being inserted into and supported by the protrusion of the fixing jig part, and on which the edge of the functional film part is seated on an upper portion, and a joining frame part that is joined to the support frame part together with the functional film part at an upper portion of the support frame part to prevent the functional film part from being detached, and a portion of the functional film part is inserted into and supported by the protrusion of the fixing jig part, the functional film part including an insertion area inserted into the support frame part and the joining frame part and an exposure area exposed to the outside, the joining frame part is joined to the support frame part together with the insertion area with a constant force so that the exposure area is formed straight, and the fixing jig part is characterized in that it is formed so that a load applied to the functional film part and the support frame part is distributed when the joining frame part is inserted, and the support frame part and the joining frame part have the functional film part therebetween. The functional film portion may include a support area that is in contact with the surface and a fitting area that extends from the support area and has a structure in which a portion protruding from the support frame portion is inserted into the joining frame portion when the functional film portion is folded.

[0011] In addition, the support frame part may include a joining groove in which the joining frame part is inserted at the top, a first engaging member protruding downwardly on one side adjacent to the fixed jig part to be inserted into the third engaging member, and a vertical bar protruding upwardly between the joining groove and the first engaging member and inserted into the joining frame part.

[0012] And the above-mentioned joining frame part includes a joining bar formed long enough to be inserted into the joining groove in the body of the above-mentioned joining frame part, and the joining bar has an outer surface facing the fixing jig part that protrudes to a predetermined extent so that the functional film part is not detached and can be joined to the joining groove.

[0013] In addition, the above-described coupling frame part may include a twin groove into which the fourth engaging member and the vertical bar are inserted together on one side of the body of the above-described coupling frame part toward the fixed jig part, and a second engaging member that extends downward and protrudes from the body of the above-described coupling frame part toward the fixed jig part with the twin groove interposed therebetween and is inserted into the fourth engaging member.

[0014] And the support frame portion may include a third protrusion protruding between the first protrusion and the second protrusion in the fitting area, and the third protrusion may include a second catch member having an end formed to protrude in a predetermined manner toward the side surface of the second protrusion.

[0015] In addition, the vertical bar includes a middle portion extending upward from the body of the support frame portion, and a terminal portion extending from the middle portion and inserted into the twin groove, and in surface contact with the inner upper surface and side surface of the twin groove, and the circumference of the terminal portion can be formed relatively larger than the circumference of the middle portion.

[0016] And the fourth catch member can be inserted into the twin groove together with the terminal portion by contacting the lower portion of the terminal portion.

[0017] In addition, the fixed jig portion may be removed while the support frame portion and the coupling frame are combined together with the functional film portion, and an adhesive may be applied to the portion from which the fixed jig portion has been removed.

[0018] And it may include a step of arranging a fixed jig part on the floor, a step of settling a support frame part adjacent to the fixed jig part, such that a part of the support frame part is inserted into the fixed jig part, a step of settling a functional film part on top of the support frame part, a step of arranging a joining frame part on top of the functional film part in a state where it can be inserted into the fixed jig part, a step of pressing the joining frame part so that the joining frame part is inserted into the support frame part with the functional film part therebetween, and a step of bonding the support frame part and the joining frame part.

[0019] According to the present invention, a film that can replace glass is provided between a pair of glasses in a double-glazed glass, thereby reducing the weight by 33% compared to existing double-glazed glass.

[0020] And when the functional film portion is fixed between the support frame portion and the joining frame portion, it has the effect of preventing wrinkles from occurring in the functional film portion.

[0021] In addition, it has the effect of preventing breakage and damage to parts by having a structure that distributes the load when the joint frame is pressurized and combined with the support frame part.

[0022] The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned will be clearly understood by those skilled in the art from the description of the claims.

[0030] Hereinafter, preferred embodiments of the present invention, which can specifically realize the objectives of the present invention, will be described with reference to the attached drawings. In describing the present embodiments, identical names and symbols will be used for identical components, and additional descriptions thereof will be omitted.

[0031] The present invention will be described in detail with reference to the drawings.

[0032] FIG. 1 is a drawing showing a perspective view of a double-layer glass (10) mounted on a window in a double-layer glass (10) and a method for manufacturing double-layer glass (10) according to one embodiment of the present invention, and FIG. 2 is a cross-sectional view of a double-layer glass (10) in a method for manufacturing double-layer glass (10) and a double-layer glass (10) manufactured through the method according to one embodiment of the present invention.

[0033] First, the present invention can largely include a functional film portion (200), a support frame portion (500), and a combination frame portion (300).

[0034] The functional film portion (200) is formed to be relatively thinner than glass, and an insulating coating layer and an ultraviolet ray blocking coating layer can be formed.

[0035] For example, the functional film section (200) is coated thinly with a metal or metal oxide such as silver, so that the transmittance of visible light among the wavelengths of sunlight is similar to that of general glass, but infrared rays are reflected, thereby minimizing the movement of heat and making it effective for indoor heat management.

[0036] In other words, it can reflect indoor heating heat and send it back indoors, and in the summer, it can block radiant heat generated from the sun outdoors from entering indoors, thereby increasing insulation.

[0037] As illustrated, the double-layer glass (10) according to one embodiment of the present invention can be applied to structures in which glass is used, such as system windows (20) or windows, and is characterized in that a functional film portion (200) replaces the glass between a pair of glasses.

[0038] The double-layer glass (10) according to the present invention can be made by placing a functional film portion between glasses facing each other in parallel and binding the edges of the functional film portion.

[0039] Here, the first glass (120) and the second glass (140) are placed spaced apart from each other, and a functional film portion (200) is placed between the first glass (120) and the second glass (140).

[0040] The first glass (120) will be referred to as the upper first glass (120) and the lower second glass (140) according to the positions shown in the drawing.

[0041] Continuing, the distances between the first glass (120), the functional film portion (200), and the second glass (140) may each have the same separation distance.

[0042] Looking at a cross-sectional view of a double-layer glass (10) according to one embodiment of the present invention, a first glass (120), a second glass (140) and a functional film portion (200) are arranged, and the functional film portion (200) is fixed by a support frame portion (500) and a joining frame portion (300).

[0043] Specifically, the support frame part (500) may be arranged on one side of the functional film part (200), and the joining frame part (300) may be arranged on the other side of the functional film part (200), so that the support frame part (500) and the joining frame part (300) may be combined.

[0044] The support frame part (500) may be arranged along the edge of the functional frame part, one side of which is in contact with the glass, and the other side of which is inserted when the functional film part (200) is folded while the joining frame part (300) is inserted, and may have a structure in which a part of the joining frame part (300) is joined.

[0045] The joining frame part (300) has a structure that can be fitted and joined to the supporting frame part (500) together with the functional film part (200), and can be configured so that glass is in contact with one side.

[0046] In a state where the functional film portion (200) is combined with the joining frame portion (300) and the support frame portion (500), the first glass (120) and the second glass (140) are placed on the upper and lower portions, respectively, and an adhesive (800) is applied to the edges to form a double-layer glass (10).

[0047] According to one embodiment of the present invention, the double-layer glass (10) is fixed by a support frame part (500) and a joining frame part (300) so that the tension of the functional film part (200) is maintained. The support frame part (500) and the joining frame part (300) that fix the functional film part (200) will be described in detail with reference to FIGS. 3 and 4.

[0048] The configuration of the present invention for this purpose includes a fixed jig part (700), a support frame part (500), and a joining frame part (300). The fixed jig part (700) has a rough shape, and the lower surface of the body is in contact with the floor surface to distribute the load. A protrusion protruding upward on a vertical surface adjacent to the functional film part (200) of the body may include a third catch member (740) into which the support frame part (500) is inserted, and a fourth catch member (720) into which the joining frame part (300) is inserted.

[0049] And the fourth catch member (720) and the third catch member (740) can be formed to be spaced apart from each other.

[0050] In detail, we will explain the organic connection relationship through drawings.

[0051] FIG. 3 is a drawing for explaining the appearance of a fixed jig part (700) installed to manufacture a double-layered glass (10) and a double-layered glass (10) manufacturing method according to one embodiment of the present invention.

[0052] The fixed jig part (700) is configured to support a load by being inserted and connected to the joint frame part (300) and the support frame part (500), and is configured to prevent the load from being applied solely to the support frame part (500) when the joint frame part (300) is connected to the support frame part (500) by a separate press device (not shown).

[0053] First, the functional film portion (200) may include an insertion area that is joined between the support frame portion (500) and the joining frame portion (300), and an exposure area in which the front and back surfaces are exposed to the outside.

[0054] The functional film portion (200) can be inserted into the support frame portion (500) and the joint frame portion (300) by applying pressure to the joint frame portion (300) while the insertion area is positioned on the upper portion of the support frame portion (500).

[0055] And since the insertion area is zigzag-fitted when the support frame part (500) and the joining frame part (300) are joined, it can be placed on the upper part of the support frame part (500) with a certain amount of space.

[0056] As shown, the support frame part (500) and the coupling frame part (300) are formed in a form in which a protrusion and a groove are coupled, and the functional film part (200) can be coupled between the support frame part (500) and the coupling frame part (300) while wrapping around the circumference of the protrusion.

[0057] And the fixed jig part (700) supports the support frame part (500) and the joining frame part (300), and includes a contact member (760, 780) on the lower surface to distribute the load applied to the support frame part (500). A detailed description of the fixed jig part (700) will be described later.

[0058] The main feature of the present invention is that the support frame part (500), the coupling frame part (300), and the fixed jig part (700) are organically coupled to each other so that the load is distributed rather than concentrated on the support frame part (500). The structures of the support frame part (500), the coupling frame part (300), and the fixed jig part (700) for this purpose will be described in detail with reference to FIGS. 4 to 6.

[0059] FIG. 4 is a drawing for explaining a joining frame part (300) in a double-layered glass (10) and a method for manufacturing double-layered glass (10) according to one embodiment of the present invention, FIG. 5 is a drawing for explaining a support frame part (500) in a double-layered glass (10) and a method for manufacturing double-layered glass (10) according to one embodiment of the present invention, and FIG. 6 is a drawing for explaining a fixing jig part (700) in a double-layered glass (10) and a method for manufacturing double-layered glass (10) according to one embodiment of the present invention.

[0060] First, the support frame part (500) may include a joining groove (510) into which a joining frame part (300) is inserted together with a functional film part (200) on the upper side, a first joining member (520) that protrudes downwardly so that a third joining member (740) is inserted on one side adjacent to the fixed jig part (700), and a vertical bar (540) that protrudes upwardly between the joining groove (510) and the first joining member (520) and is inserted into the joining frame part (300).

[0061] The coupling frame part (300) coupled thereto includes a coupling bar (310) formed long to be inserted into a coupling groove (510) in the body of the coupling frame part (300), and the coupling bar (310) can be coupled to the coupling groove (510) by having an outer surface facing the fixing jig part (700) protruding to a predetermined degree so that the functional film part (200) does not come off.

[0062] And the coupling frame part (300) may include a twin groove (340) in which a fourth engaging member (720) and a vertical bar (540) are inserted together on one side of the body of the coupling frame part (300) toward the fixed jig part (700), and a second engaging member (320) that extends downward and protrudes toward the fixed jig part (700) from the body of the coupling frame part (300) with the twin groove (340) interposed therebetween and is inserted into the fourth engaging member (720).

[0063] Here, the first catch member (520) and the second catch member (320) have the same L shape and can be formed to extend from each body toward the fixed jig portion (700).

[0064] And the first catch member (520) can be inserted into the third catch member (740), and the second catch member (320) can be inserted into the fourth catch member (720). To this end, the fourth catch member (720) and the third catch member (740) are formed in an L shape on one side of the body of the fixed jig portion (700), and specifically, on one side facing the functional film portion (200), the fourth catch member (720) can be formed in an L shape on the upper side, and the third catch member (740) can be formed in an L shape on the lower side.

[0065] As mentioned above, the fourth catch member (720) and the vertical bar (540) are inserted simultaneously into the twin groove (340) of the joining frame part (300). Specifically, this can be structured such that a second catch member (320) extending from the body of the joining frame part (300) shown in FIG. 4 toward the fixed jig part (700) and a twin groove (340) formed between the second catch member (320) and the joining frame part are formed, and the vertical bar (540) and the fourth catch member (720) are inserted into the twin groove (340).

[0066] And the lower surface of the body of the coupling frame part (300) may include a coupling bar (310) and a hooking projection (312) that protrude downward and are inserted into the support frame part (500).

[0067] The joining bar (310) is formed long, and a hook projection (312) is formed to protrude along the circumference toward the fixed jig portion (700), and the hook projection (312) can prevent the functional film portion (200) from being detached by pressing the surface of the insertion area between the joining frame portion (300) and the support frame portion (500).

[0068] The coupling bar (310) can be inserted into the coupling groove (510) of the support frame part (500).

[0069] The support frame part (500) illustrated in FIG. 5 may have a coupling groove (510) into which a coupling bar (310) is inserted and a hooking groove (512) into which a hooking projection (312) is inserted formed on the upper part of the body of the support frame part (500).

[0070] As described above, this is to prevent the insertion area of ​​the functional film portion (200) from being detached while inserted, and the hooking dolly protrudes toward the fixing jig portion (700), so that the functional film portion (200) can be caught in the opposite direction to the detachment direction, thereby increasing the fixing force.

[0071] And, a vertical bar (540) can be formed in a portion spaced apart from the joining groove (510) in the direction of the fixed jig portion (700) on the upper surface of the support frame portion (500).

[0072] The vertical bar (540) is formed long and inserted into the twin groove (340). The vertical bar (540) includes a middle portion (542) that extends upward from the support frame portion (500) and a terminal portion (544) that extends from the middle portion (542) toward the twin groove (340). The terminal portion (544) may be formed to have a relatively larger circumference than the middle portion (542).

[0073] Specifically, the boundary connecting the middle portion (542) to the distal portion (544) may be formed as a step on one side adjacent to the functional film portion (200) and on the other side adjacent to the fixed jig portion (700). That is, the other side adjacent to the fixed jig portion (700) may have a shape in which the distal portion (544) protrudes to a predetermined degree.

[0074] The first surface (544a), which is the upper surface of the terminal portion (544) of the shape as above, and the second surface (544b), which is the side surface of the terminal portion (544), are in contact with the inner surface of the twin groove (340) without any gaps, and the fourth catch member (720) is in surface contact with the third surface (544c), which is the lower surface of the terminal portion (544) formed by the step, so that it can be inserted into the twin groove (340).

[0075] In this way, when the fourth catch member (720) and the vertical bar (540) are inserted together into the twin home (340), the combined frame is structurally supported when combined with the support frame, so that the applied force can be distributed to the fixed jig portion (700) and the support frame portion.

[0076] Meanwhile, the fixed jig portion (700) may have a fourth catch member (720) formed on one side of the body facing the functional film portion (200) and a third catch member (740) formed below the fourth catch member (720). Here, the third catch member (740) is formed to protrude a certain amount toward the functional film portion (200) more than the fourth catch member (720) and is formed to be thicker than the third catch member (740) in order to withstand the load well.

[0077] And the fixed jig (700) may include a floor point contact member (760) and a floor surface contact member (780) that come into contact with the floor at the lower part of the body.

[0078] The floor contact member (760) is formed at a position adjacent to the functional film member (200) at the lower part of the fixed jig member (700) body, and the floor surface contact member (780) can be formed at a position spaced outward.

[0079] The floor contact member (760) and the floor surface contact member (780) may have a structure that supports a load by being formed to protrude toward the floor surface in the opposite direction to the third catch member (740) and the fourth catch member (720). The purpose of forming the floor surface contact member (780) and the floor surface contact member (760) in this way is to increase productivity by reducing the weight of the fixed jig part (700), and to structurally distribute the load by being arranged out of alignment with the third catch member (740) and the fourth catch member (720) when the load is transmitted vertically.

[0080] The double-layer glass (10) of the present invention can be completed by removing the fixed support portion while the functional film portion (200) is fixed by being combined with the support frame portion (500) and the joining frame portion (300), and applying adhesive to the portion from which the fixing jig portion (700) has been removed.

[0081] And it can be applied to sliding doors, curtain walls, etc. by combining with a window frame or window (20).

[0082] Next, a method for manufacturing the double-layer glass (10) of the present invention will be described.

[0083] FIG. 7 is a flowchart showing a method for manufacturing a double-layer glass (10) and a double-layer glass (10) according to one embodiment of the present invention, and FIG. 9 is a flowchart showing a method for manufacturing a four-layer glass in a double-layer glass (10) and a double-layer glass (10) manufacturing method according to a modified embodiment of the present invention.

[0084] First, a method for manufacturing a double-layer glass (10) according to one embodiment of the present invention relates to a triple-layer glass (10), and first, a fixing jig (700) can be installed on the bottom surface (A).

[0085] And the support frame part (500) can be fixed to the fixed jig part (700) (B). At this time, the second member (548) of the fixed jig part (700) can be fixed so that it can be inserted into the second clasp (704).

[0086] As above, the fixed jig part (700) and the support frame part (500) are connected to the floor surface so that they can respond to upper pressure and can be supported without shaking.

[0087] Continuing, the functional film portion (200) is positioned and secured on the upper part of the support frame portion (500) (C). At this time, the functional film portion (200) may have a larger area than the outermost part of the support frame.

[0088] This is because the functional film portion (200) is inserted in a zigzag shape while being inserted in the fitting area (440), so that it is formed to a predetermined size to increase the contact area between the first and second protrusions and prevent them from coming off.

[0089] The joint frame part (300) is then positioned so that it can be inserted into the fixed jig part (700) and the support frame part (500) (D).

[0090] And when the joint frame part (300) is pressed by an external press device or a device that can apply pressure with an even vertical force, the functional film part (200) is fixed between the joint frame part (300) and the support frame while maintaining tension (E).

[0091] The double-layer glass (10) can be completed by continuously placing the first glass (120) and the second glass (140) on the upper and lower sides and applying side adhesive (800) (F).

[0092] As described above, preferred embodiments of the present invention have been described. It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms, in addition to the embodiments described above, without departing from the spirit or scope thereof. Therefore, the above-described embodiments should be considered illustrative rather than restrictive, and accordingly, the present invention is not limited to the above description, but may be modified within the scope of the appended claims and their equivalents.
