Description

Composite insulation cover window frame

[0001] The present invention relates to a composite insulation cover window frame, and more particularly, to a composite insulation cover window frame capable of implementing the colors of the front and rear covers of the window frame body in various colors by attaching a window frame body made of PVC material and a cover made of aluminum material to the front and rear sides of the window frame, and further capable of forming a hollow layer and an insulating space including a still air layer without convection in the internal space of the window frame body, and forming an insulating space including an air layer in the space between the window frame body and the cover, thereby blocking heat transfer of external air.

[0002] Windows are generally installed on the walls of a building to spatially separate the interior and exterior. These windows serve several purposes: selectively blocking the interior and exterior of a building, while also providing a visual view of the exterior from the inside. Because of this function, windows often have lower soundproofing and insulation performance than walls. Therefore, technologies are being developed to enhance their soundproofing and insulation. Therefore, further research is needed into technologies that simultaneously provide the visual benefits of windows and their thermal insulation.

[0003] In order to solve the above-described conventional problems, the present invention provides a composite insulating cover window frame that can implement the colors of the front and rear covers of the window frame body in various colors by attaching a window frame body made of PVC material and an aluminum material cover to the front and rear sides of the window frame, and further forms a hollow layer and an insulating space including a still air layer without convection in the internal space of the window frame body, and forms an insulating space including an air layer in the space between the window frame body and the cover, thereby blocking heat transfer of external air.

[0004] In order to achieve the above object, a composite insulating cover window frame according to one embodiment of the present invention comprises: a window frame body part having a glass window attached to an upper portion thereof and a lower portion thereof sliding along a rail of a window frame part; a first insulating cover part attached to a front surface of the window frame body part and forming a first insulating space between the window frame body part and the window frame body part; a second insulating cover part attached to a rear surface of the window frame body part and forming a second insulating space between the window frame body part and the window frame body part; a fixed cover part attached to an upper portion of the second insulating cover part and fixing a glass window attached to an upper portion of the window frame body part; And a window frame part located at the lower portion of the window frame body part, having a rail so that the window frame body part slides along the rail; wherein the window frame body part includes a first hollow part formed at the upper portion in contact with the first insulating cover part, a second hollow part formed at the lower portion of the first hollow part and formed at the lower portion of the glass window, a third hollow part formed at the lower portion in contact with the first insulating cover part, and a fourth hollow part formed at the lower portion in contact with the second insulating cover part, wherein the window frame body part is made of a plastic material, and a still air layer without convection is formed inside the first hollow part, the second hollow part, the third hollow part, and the fourth hollow part.

[0005] The window frame body part includes a third insulating space located between the first insulating space and the second insulating space, and an air layer is formed inside the first insulating space and the second insulating space, and a still air layer without convection is formed inside the third insulating space.

[0006] The above window frame body portion includes a first diagonal structural portion positioned between the first hollow portion and the second hollow portion, and a second diagonal structural portion positioned between the second hollow portion and the fixed cover portion, wherein the first diagonal structural portion and the second diagonal structural portion form a diagonal surface with respect to the horizontal plane of the glass window, and together with the second hollow portion, absorb impact due to external force applied to the glass window.

It is characterized by comprising 0.5 to 5 parts by weight of a crosslinking agent and 2 to 10 parts by weight of a pigment.

[0008] The inner space of the above rail is characterized in that a rib is formed.

[0010] In addition, the present invention forms a still air layer without convection through a hollow portion and an insulating space provided in a window frame body, and forms an air layer through an insulating space between the window frame body and the first insulating cover part and the second insulating cover part, thereby having the effect of increasing the insulating effect through an air layer with low thermal conductivity.

[0011] In addition, the present invention forms a diagonal structure on the side of the hollow portion where the glass window is placed, and forms an air layer in the hollow portion, so that the diagonal structure and the air layer have the effect of absorbing external force due to impact occurring during an earthquake.

[0022]

[0023] Hereinafter, a composite insulation cover window frame according to an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is an exploded cross-sectional view of a composite insulation cover window frame according to an embodiment of the present invention, Fig. 2 is an assembled cross-sectional view of a composite insulation cover window frame according to an embodiment of the present invention, and Fig. 3 shows a window frame portion in a composite insulation cover window frame according to an embodiment of the present invention. Referring to Figs. 1 to 3, a composite insulation cover window frame according to an embodiment of the present invention may be configured to include a window frame body portion (10), a first insulation cover portion (20), a second insulation cover portion (30), a fixed cover portion (40), and a window frame portion (50).

[0024] The window frame body (10) has a glass window (W) attached to the upper part, and the lower part slides along the rail (51) of the window frame (50). The window frame body (10) constitutes the body of the window frame, and the window frame body (10) can be made of PVC, a plastic material. The window frame body (10) has a glass window (W) fixed to the upper part, and has a rail groove (14) provided at the lower part to slide along the rail (51) of the window frame (50).

[0025] The first insulating cover part (20) is attached to the front of the window frame body part (10) and forms a first insulating space (21) between it and the window frame body part (10). The first insulating cover part (20) is positioned in the direction in which the window faces the interior and is attached to the front of the window frame body part (10). The first insulating cover part (20) can be made of aluminum, which is a metal material.

[0026] The second insulating cover part (30) is attached to the rear side of the window frame body part (10) and forms a second insulating space (31) between it and the window frame body part (10). The second insulating cover part (30) is positioned in the direction in which the window faces the outside and is attached to the rear side of the window frame body part (10). The second insulating cover part (30) can be made of aluminum, which is a metal material.

[0027] The fixed cover part (40) is attached to the upper part of the second insulating cover part (30) and fixes the glass window (W) attached to the upper part of the window frame body part (10). The fixed cover part (40) can be made of PVC, a plastic material.

[0028] The window frame part (50) is located at the lower part of the window frame body part (10) and has a rail (51) so that the window frame body part (10) slides along the rail (51). The window frame part (50) may have a plurality of rails (51) so that a plurality of window frame bodies (10) may be located at the upper part of the window frame part (50). Referring to FIG. 3, a rib (52) may be formed in the internal space of the rail (51). The rib (52) serves as a kind of skeletal structure to support the rail (51), prevent distortion of the rail (51) when a hole is drilled in the rail (51) for drainage, and prevent buckling of the rail (51) due to the load of the glass window (W) during long-term use. In FIG. 3, one rib (52) is formed, but if necessary, a plurality of ribs (52) may be formed inside the rail (51). The window frame (50) can be made of aluminum, a metal material.

[0029] The window frame body (10) includes a first hollow portion (12) formed at the upper part in contact with the first insulating cover portion (20), a second hollow portion (13) formed at the lower part of the first hollow portion (12) and formed at the lower part of the glass window (W), a third hollow portion (14) formed at the lower part in contact with the first insulating cover portion (20), and a fourth hollow portion (15) formed at the lower part in contact with the second insulating cover portion (30). The window frame body (10) is made of a plastic material, and a still air layer without convection is formed inside the first hollow portion (12), the second hollow portion (13), the third hollow portion (14), and the fourth hollow portion (15). The air layer has excellent insulating performance that is not inferior to any insulating material, because the specific heat of air is lower than that of other materials, thereby increasing the thermal resistance of the window frame. The phenomenon of heat energy movement within a material occurs in the order of metal, non-metal, liquid, and gas. In particular, the still air layer can be said to be the material that has the greatest resistance to heat conduction. In the present invention, the interiors of the first hollow portion (12), the second hollow portion (13), the third hollow portion (14), and the fourth hollow portion (15) are filled with air, and the window frame body portion (10) is made of PVC, a plastic material. Since PVC has low thermal conductivity, the outside air cannot affect the air inside the first hollow portion (12), the second hollow portion (13), the third hollow portion (14), and the fourth hollow portion (15), and therefore the air inside the first hollow portion (12), the second hollow portion (13), the third hollow portion (14), and the fourth hollow portion (15) forms a still air layer in which no convection occurs. Therefore, the still air layers of the first hollow portion (12), the second hollow portion (13), the third hollow portion (14), and the fourth hollow portion (15) have an excellent insulating effect that insulates the indoor air from the outdoor air.

[0030] The window frame body part (10) includes a third insulating space (11) located between the first insulating space (21) and the second insulating space (31), and an air layer is formed inside the first insulating space (21) and the second insulating space (31), and a still air layer without convection is formed inside the third insulating space (11). As described above, air has excellent insulating performance, and still air is an excellent insulating material that does not conduct heat well. The window frame body part (10) is made of PVC, which is a plastic material, and the first insulating cover part (20) and the second insulating cover part (30) are made of aluminum, which is a metal material. Therefore, in the first insulating space (21) and the second insulating space (31) surrounded by the metal material and the plastic material, an air layer with convection is formed by heat conduction through the metal material, and in the third insulating space (11) surrounded by the plastic material, a still air layer without convection is formed. Since the air layers of the first insulating space (21) and the second insulating space (31) and the still air layer of the third insulating space (11) have different thermal conductivities, the insulating effect is superior to that of insulating materials having the same thermal conductivity. That is, since the still air layer of the third insulating space (11) has lower thermal conductivity than a general air layer, heat passing through the air layers of the first insulating space (21) and the second insulating space (31) is not well transferred to the still air layer of the third insulating space (11) which has lower thermal conductivity, and thus excellent insulating performance can be exhibited.

[0031] In addition, the first insulating space (21), the second insulating space (31), and the third insulating space (11) can be filled with insulating material instead of air. The first insulating space (21), the second insulating space (31), and the third insulating space (11) are filled with insulating material, and assuming that the thermal conductivity of the first insulating material filled in the first insulating space (21) is k1, the thermal conductivity of the second insulating material filled in the second insulating space (31) is k2, and the thermal conductivity of the third insulating material filled in the third insulating space (11) is k3, it is characterized in that k1< k3< k2. The lower the thermal conductivity, the less well heat is transmitted, resulting in a better insulating effect. If the thermal conductivity of the third insulation material of the third insulation space (11) located in the middle is made lower than the thermal conductivity of the second insulation material of the second insulation space (31) facing the outdoors, when the cold air from the outdoors transmitted through the second insulation material comes into contact with the third insulation material having lower thermal conductivity than the second insulation material, the cold air will have a lower probability of heat being transferred to the third insulation material due to the difference in thermal conductivity because the third insulation material has lower thermal conductivity. In addition, the cold air passing through the third insulation material comes into contact with the first insulation material having lower thermal conductivity than the third insulation material, and the cold air will have a lower probability of heat being transferred to the first insulation material due to the difference in thermal conductivity. As described above, by arranging the insulation material so that the thermal conductivity is lower in the direction from the outdoors to the indoors, the cold air can be prevented from flowing into the indoors. In other words, when the cold air flows from the outdoors to the indoors in the direction of lower thermal conductivity, the difference in thermal conductivity prevents heat transfer of the cold air, thereby increasing the insulation effect. Therefore, in order to increase the insulation effect, it is desirable that k1 < k3 < k2.

[0032] The first, second and third insulating materials are manufactured by extruding an insulating composition comprising at least one binder resin selected from the group consisting of polyvinyl acetate, polyacrylic, polyamide, polyurethane and polyester, glass fiber and a flame retardant, wherein the composition ratio of the glass fiber of the first insulating material is higher than the composition ratio of the glass fiber of the third insulating material, and the composition ratio of the glass fiber of the third insulating material is higher than the composition ratio of the glass fiber of the second insulating material. Here, the insulating composition preferably includes 30 to 50 parts by weight of the binder resin, 20 to 50 parts by weight of the glass fiber, and 10 to 20 parts by weight of the flame retardant. The binder resin preferably has a thermal conductivity of 0.20 W / mK or less, and if the thermal conductivity exceeds 0.20 W / mK, there is a disadvantage in that the insulating effect is reduced. The glass fiber preferably has a length of 1 to 5 mm, and the aspect ratio of the glass fiber is preferably 2 to 100. As the flame retardant, one of a halogen-based flame retardant, a phosphorus-based flame retardant, and an inorganic flame retardant can be selected and used. Glass fiber has a thermal conductivity of 0.036 W / mK to 0.050 W / mK, which is lower than that of plastic, making it suitable for use as an insulator. Therefore, the thermal conductivity of the insulator can be adjusted by adjusting the composition ratio of the glass fiber. Specifically, the first insulator may include 30 to 50 parts by weight of a binder resin, 40 to 50 parts by weight of glass fiber, and 10 to 20 parts by weight of a flame retardant, the third insulator may include 30 to 50 parts by weight of a binder resin, 30 to 40 parts by weight of glass fiber, and 10 to 20 parts by weight of a flame retardant, and the second insulator may include 30 to 50 parts by weight of a binder resin, 20 to 30 parts by weight of glass fiber, and 10 to 20 parts by weight of a flame retardant. The glass fiber composition ratio can be adjusted so that the thermal conductivity is k1< k3< k2 by setting it higher in the third insulation than in the second insulation, and higher in the first insulation than in the third insulation.Here, the binder resin is preferably included in an amount of 30 to 50 parts by weight. If the binder resin is included in an amount of less than 30 parts by weight, there will be a problem in molding into an insulating material due to insufficient binder resin, and if the binder resin is included in an amount of more than 50 parts by weight, there will be an excess of binder resin, which may require a long time to dry after molding into an insulating material. Therefore, the binder resin is preferably included in an amount of 30 to 50 parts by weight. In addition, the glass fiber is preferably included in an amount of 20 to 50 parts by weight. If the glass fiber is included in an amount of less than 20 parts by weight, there will be a problem in that the insulating effect is reduced, and if the glass fiber is included in an amount of more than 50 parts by weight, there will be a problem in molding into an insulating material. Therefore, the glass fiber is preferably included in an amount of 20 to 50 parts by weight. In addition, it is preferable to include 10 to 20 parts by weight of the flame retardant. If the flame retardant is included in an amount less than 10 parts by weight, the flame retardant effect may be reduced and the insulation may combust. If the flame retardant is included in an amount greater than 20 parts by weight, there may be problems in forming the insulation. Therefore, it is preferable to include 10 to 20 parts by weight of the flame retardant.

[0033] The first insulating cover part (20) has a first protrusion (22) corresponding to the first groove (19A) located at the upper part of the first hollow part (12), and a second protrusion (23) corresponding to the second groove (19B) located at the lower part of the third hollow part (14). In addition, the second insulating cover part (30) has a third protrusion (32) corresponding to the third groove (19C) located at the upper part of the third insulating space (11), and a fourth protrusion (33) corresponding to the fourth groove (19D) located at the lower part of the fourth hollow part (15). The first protrusion (22) and the second protrusion (23) of the first insulation cover part (20) are assembled by fitting them into the first groove (19A) and the second groove (19B) of the window frame body part (10), and the third protrusion (32) and the fourth protrusion (33) of the second insulation cover part (30) are assembled by fitting them into the third groove (19C) and the fourth groove (19D) of the window frame body part (10). This method has the advantage of not easily coming off after assembly due to the structure of the protrusions and grooves.

[0034] The window frame body (100) includes a first diagonal structure (16) positioned between the first hollow portion (12) and the second hollow portion (13), and a second diagonal structure (17) positioned between the second hollow portion (13) and the fixed cover portion (40). The first diagonal structure (16) and the second diagonal structure (17) form a diagonal surface with respect to the horizontal plane of the glass window (W) and, together with the second hollow portion (13), absorb impact due to external force applied to the glass window (W). The glass window (W) is placed on the upper portion of the second hollow portion (13), and the first diagonal structure (16) and the second diagonal structure (17) having a diagonal structure are provided on the side surface of the second hollow portion (13) on which the glass window (W) is placed in order to absorb impact due to external force applied to the glass window (W) when an earthquake occurs. The first diagonal structure (16) and the second diagonal structure (17) do not form a plane that is horizontal to the horizontal plane of the glass window, but form an diagonal plane at an angle of 30 to 80 degrees to the horizontal plane of the glass window. The external force applied to the glass window (W) through the diagonal plane is not directly transmitted to the second hollow portion (13), but is transmitted in a relaxed state through the diagonal plane. In addition, since the second hollow portion (13) includes an air layer inside, the transmitted external force is absorbed by the air layer inside the second hollow portion (13). Therefore, the present invention has an advantage in that the impact caused by the external force applied to the glass window (W) when an earthquake occurs can be absorbed by the diagonal plane of the first diagonal structure (16) and the second diagonal structure (17) and the air layer inside the second hollow portion (13).

[0035] The first insulating cover part (20) and the second insulating cover part (30) are made of a metal material, and the first insulating cover part (20) and the second insulating cover part (30) can be coated with different colors. The first insulating cover part (20) and the second insulating cover part (30) are made of aluminum, which is a light metal material, i.e., aluminum extrusion. The first insulating cover part (20) and the second insulating cover part (30) made of aluminum extrusion are light and sturdy, but have poor insulating properties, so they are treated with an insulating color coating. As illustrated in FIG. 3, in the present invention, the first insulating cover part (20) and the second insulating cover part (30) can be coated with different colors to double the aesthetics of the window frame. For example, in the case of a kindergarten where children live, the second insulating cover part (30) facing outdoors can be color-coated with a bright primary color, and the first insulating cover part (20) facing indoors can be color-coated with a pastel tone that causes less eye fatigue. In addition, when it is necessary to repaint the color coating after installing the window frame, there is an advantage in that the first insulating cover part (20) and the second insulating cover part (30) can be repainted separately. In addition, the window frame part (50) is made of aluminum, and as shown in FIG. 3, it can be coated with the same color as the first insulating cover part (20) and the second insulating cover part (30). The part of the window frame part (50) facing indoors can be coated with the same color as the first insulating cover part (20), and the part of the window frame part (50) facing outdoors can be coated with the same color as the second insulating cover part (30).

[0036] The first insulation cover part (20) and the second insulation cover part (30) are triple-coated to improve insulation effect and durability of the coating. The first insulating cover part (20) and the second insulating cover part (30) are treated with a triple coating, and the composition of the first coating includes 30 to 40 parts by weight of epoxy resin, 3 to 5 parts by weight of aluminum oxide, 10 to 20 parts by weight of solvent, 0.5 to 5 parts by weight of thickener, and 0.5 to 5 parts by weight of crosslinking agent, the composition of the second coating includes 30 to 40 parts by weight of polyethylene resin, 10 to 20 parts by weight of solvent, 0.5 to 5 parts by weight of thickener, and 0.5 to 5 parts by weight of crosslinking agent, and the composition of the third coating includes 30 to 40 parts by weight of epoxy resin, 10 to 15 parts by weight of aluminum oxide, 10 to 20 parts by weight of solvent, 0.5 to 5 parts by weight of thickener, 0.5 to 5 parts by weight of crosslinking agent, and 2 to 10 parts by weight of pigment. Since the first insulating cover part (20) and the second insulating cover part (30) are made of aluminum, their insulating properties are poor. Therefore, in the present invention, the first insulating cover part (20) and the second insulating cover part (30) are treated with a triple coating. In the triple coating, the first coating is for surface treatment so that the coating can be well added to the surfaces of the first insulating cover part (20) and the second insulating cover part (30), the second coating is for coating layer bonding so that the first and third coatings can be well bonded, and the third coating is for insulating the first insulating cover part (20) and the second insulating cover part (30). If the triple coating is performed in sequence and in parallel with drying, the first insulating cover part (20) and the second insulating cover part (30) can have an additional insulating effect.

[0037] In the above triple coating, epoxy resin is the main component of epoxy paint, and it is preferably included in an amount of 30 to 40 parts by weight in the present invention. If the epoxy resin is included in an amount of less than 30 parts by weight, the adhesion of the coating is reduced, and if the epoxy resin is included in an amount of more than 40 parts by weight, the solvent content increases, which is harmful to the human body. Therefore, it is preferable to include 30 to 40 parts by weight of epoxy resin. In the first coating, 3 to 5 parts by weight of aluminum oxide is added for the purpose of insulation, and in the second coating, aluminum oxide is not added because the purpose is to bond the coating layers, and in the third coating, 10 to 15 parts by weight of aluminum oxide is added for the purpose of insulation. Aluminum oxide is a ceramic material with excellent heat resistance and is used as an insulator. Next, the solvent of the present invention includes at least one selected from the group consisting of diethylene glycol monoethyl ether, diethylene glycol monobutyl ether, ethylene glycol monobutyl ether, and propylene glycol. Here, the solvent is preferably included in an amount of 10 to 20 parts by weight. If the solvent is included in an amount of less than 10 parts by weight, the adhesion of the coating is reduced, and if the solvent is included in an amount of more than 20 parts by weight, there is a problem that the coating becomes gelatinous due to increased resin swelling. Therefore, the solvent is preferably included in an amount of 10 to 20 parts by weight. Next, the thickener improves the flowability and coating adhesion of the coating film, and the thickener of the present invention includes at least one selected from the group consisting of an acrylic thickener and a cellulose thickener. Here, the thickener is preferably included in an amount of 0.5 to 5 parts by weight. If the thickener is included in an amount of less than 0.5 parts by weight, the surface tension is lowered, causing the coating film to flow, and if the thickener is included in an amount of more than 5 parts by weight, there is a problem that the viscosity becomes too high. Therefore, it is preferable to include 0.5 to 5 parts by weight of the thickener. Next, the crosslinking agent of the present invention includes at least one selected from the group consisting of polyethylene, polyvinyl chloride, chlorinated polyethylene, EVA, and polystyrene. Here, the crosslinking agent is 0.It is preferable to include 5 to 5 parts by weight of the crosslinking agent, but if it includes less than 0.5 parts by weight of the crosslinking agent, it is difficult to improve the wear resistance and scratch resistance, and if it includes more than 5 parts by weight of the crosslinking agent, the particle distribution increases, resulting in reduced scratch resistance. In the case of the third coating, a pigment is added to enhance the appearance of the first insulating cover part (20) and the second insulating cover part (30). Here, it is preferable to include 2 to 10 parts by weight of the pigment, but if it includes less than 2 parts by weight of the pigment, the hiding power of the coating decreases, and if it includes more than 10 parts by weight of the pigment, the adhesion of the coating decreases. Therefore, it is preferable to include 2 to 10 parts by weight of the pigment.

[0038] The present invention is not limited to the above-described embodiments, but can be manufactured in a variety of different forms.
