Description

Composite insulating curtain wall window having double pane}

The present invention relates to a curtain wall window for constituting a partition wall of a building, and more particularly, by combining and forming a chassis member and a finishing member so that the laminated glass is spaced apart and inserted into a double, inherent thermal insulation of the laminated glass. Of course, through the double-layered glass to have a heat-insulating compound effect that the inner and outer insulation at the same time, it is to be able to construct a curtain wall window having excellent insulation and sound insulation effect.

After World War II, buildings changed from masonry to furniture, supporting the load only with the frame of columns and beams, the main structure of the building. Freed from the load-bearing function of the structure, it simply acts like a curtain that partitions the space.

Accordingly, the wall that acts as a curtain as described above is often called a curtain wall, and the curtain wall not only blocks rain, wind, noise, heat, etc., but also plays a large role as an exterior material, and functions as a high-rise or It is often used in skyscraper construction.

The materials for constructing the curtain wall include metal plates, glass, blocks, precast concrete, etc., and the temperature change and the vibration of the building are taken into consideration. In high-rise construction, the curtain wall is light in order to reduce the weight of the building. Material is used.

Therefore, glass panel is mainly used as the most suitable material for constituting the curtain wall in recent years, and the glass panel is manufactured in the form of a single layer or a double layer, and the selective application is made according to the importance of insulation. It is.

Looking at a conventional curtain wall window using the glass panel as described above, as shown in Figure 1, by using aluminum, etc. as shown in the chassis 100 and 100 'vertically arranged at regular intervals, the chassis 100 By using 100 ', the glass panel 110 in the form of a plate is fixed or inserted into a fixed shape, thereby ensuring excellent lightability by the glass panel 110 and at the same time allowing outdoor view to be frustrating. It has the advantage of being able to turn the field of view from the interior space.

In particular, the glass panel as described above also serves to add the beauty of the building by the beautiful surface gloss and reflected light, so the curtain wall window using the glass panel as described above is very widely applied to buildings of the near future.

However, the curtain wall window as described above has a disadvantage in that the insulation effect on the whole building is lowered due to the characteristics of the glass panel that is not excellent in insulation because it is necessary to ensure insulation only by the glass panel itself.

That is, when constructing in the form of a curtain wall window with respect to the outer wall of the building as described above, the glass panel itself serves as a heat insulating member, as is well known, the glass panel is a material having excellent heat insulating effect In other words, it is not a general masonry wall or glass panels, but rather a curtain wall by a material having insulation such as precast concrete or blocks has a disadvantage that the heat insulation is significantly reduced.

Accordingly, as the above-mentioned glass panel is applied as a multilayer glass, an attempt has been made to overcome the problem of the thermal insulation deterioration that the curtain wall window has through the heat insulation of the multilayer glass, but this is the curtain wall window due to the single-layer glass panel. Rather, it suggests improved insulation but also fails to provide satisfactory insulation.

Therefore, the curtain wall window as described above has an excellent advantage in the exterior effect and light and outdoor view, but the excessive spending of summer and winter cooling and heating costs due to the deterioration of thermal insulation remains a problem that has not been solved.

The present invention is to solve the problems described above, the first and second chassis members of the indoor side and the second chassis member is separately molded and each of the first and second chassis members are separated from each other through a separate insulating material The second chassis member on the indoor side is coupled to form a separate insulation finishing member facing the room, and through the first chassis member and the second chassis member and the finishing member to form a double insertion groove on both sides, By allowing the double curtain wall window of the form in which the multilayer glass is inserted into the double spaced apart through these double insertion grooves,

Insulation and sound insulation effect are further improved through double glazed glass along with the insulated heat of double glazed glass, and heat loss caused by conduction of cold air or heat from indoor or outdoor side by heat insulation and finishing member. It is an object of the present invention to provide a double curtain wall window of a thermally insulated composite having a feature of preventing.

The present invention for achieving the object as described above, by forming the first chassis member formed on the outer side insertion groove on both sides, and the second chassis member which is coupled to a separate finishing member at one end, respectively, the first chassis The member and the second chassis member are formed to be connected to each other by a separate heat insulating material,

Between the first chassis member and the closing member is configured to form an inner insertion groove which is arranged side by side with the outer insertion groove, the glass panel is inserted into the construction by using the outer insertion groove and the inner insertion groove. .

The present invention is to create a double layered glass with the insulator and sound insulation effect inherent in the laminated glass to produce a heat-insulating compound effect by the heat resistance and external insulation, and to further improve the sound insulation effect, Insulation material connecting the separated chassis member is to minimize the heat loss caused by the heat conduction action of the metal extrudate by blocking the conduction of cold air or heat of the indoor or outdoor side to each other, the finishing member exposed to the indoor side is heat loss again Simultaneous and beautiful decoration will be produced at the same time, it is possible to construct a double curtain wall window that the heat insulation and sound insulation effect is significantly increased compared to the conventional.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a construction state diagram of the double curtain wall window according to the present invention, Figure 3 is an exploded perspective view of the chassis assembly of the double curtain wall window according to the present invention, Figure 4 is a plan view of the chassis assembly of the double curtain wall window according to the present invention The whole view.

As shown in the figure, the double curtain wall window according to the present invention is constructed through a separate chassis assembly, wherein the chassis assembly is formed by extruding aluminum, etc., the first chassis member 10 and the second chassis member 20 which are separate from each other. ) And the finishing member 30 and the heat insulating material (40).

At this time, the first chassis member 10 is used to cut as much as necessary length in the state continuously extruded using aluminum or the like as described above, the outer side insertion groove 11 in one side eccentric form on both sides 11 'is formed, and insertion grooves 13 and 13' are formed on the other side to insert and assemble separate gaskets 60 and 60 ', and the other central portion protrudes laterally. The locking jaw portion 14 is bent.

In addition, the second chassis member 20, which is a separate component from the first chassis member 10, is also made by extrusion molding aluminum, etc., and on one side, the locking jaw portion 14 of the first chassis member 10 is formed. In the direction corresponding to) is another locking projection 21 is formed protruding, the other side is formed fitting protrusions 22, 22 'spaced apart up and down.

At this time, the separate finishing member 30, which is made of wood or synthetic resin, etc., is formed with fitting grooves 31 and 31 'having grooves on one side thereof, and the fitting grooves 31 and 31' are formed. It has a form corresponding to the fitting protrusions 22, 22 'of the second chassis member 20.

In particular, the insulating member 40, which serves to connect and couple the first chassis member 10 and the second chassis member 20 to each other, has locking grooves 41 and 41 'spaced apart from each other on both sides thereof. As formed, the first and second chassis members 10 and 20 are respectively connected and coupled to each other through the locking grooves 41 and 41 ′.

Here, the heat insulating material 40 is injection or extrusion molded through a material of high-strength polyurethane or polyamide, and as the preferred heat insulating material 40, the Azon heat insulation bar of Azon Korea Co., Ltd. is most ideal. Insulation material 40 is excellent in the effect of blocking the heat conduction is also commonly used in the field of windows and doors that focus on insulation.

Accordingly, the locking jaw portion 14 of the first chassis member 10 is inserted into the locking groove portions 41 and 41 'of one side of the heat insulating material 40, and the locking jaw portion 21 of the second chassis member 20 is inserted and locked. ) And the first and second chassis members 20 and 20 are connected to each other through the heat insulating material 40 by inserting and locking the other locking grooves 41 and 41 ′ of the heat insulating material 40. At the same time, the heat conduction effect between the first chassis member 10 and the second chassis member 20 made of a metallic material is blocked.

In particular, when the first chassis member 10 and the second chassis member 20 are connected to each other through the heat insulating material 40 as described above, one side and the second chassis member 20 of the first chassis member 10 are connected to each other. Grooves are formed between the finishing members 30 coupled to the grooves, and these grooves have inner insertion grooves 12 and 12 parallel to the outer insertion grooves 11 and 11 ′ formed in the first chassis member 10. '). Accordingly, the inner insertion grooves 12 and 12 ′ are not artificially made like the outer insertion grooves 11 and 11 ′, but are connected to the first chassis member 10 and the second chassis member 20. Accordingly, it is generated between the first chassis member 10 and the finishing member 30.

Therefore, the glass panel 50 corresponding to the outdoor side is inserted and fixed by using the outer insertion grooves 11 and 11 ', and the indoor side using the inner insertion grooves 12 and 12'. The glass panel 50 'corresponding to the insert can be fixed to construct a double curtain wall window.

In this case, the glass panels 50 and 50 ′ may use a single layer of glass, but may also use a multilayer glass having a vacuum part therein for the purpose of further improving the thermal insulation and sound insulation effects.

In addition, as the insertion grooves 13 and 13 ′ formed in the first chassis member 10, separate gaskets 60 and 60 ′ are inserted as described above, and the gaskets 60 and 60 are inserted. ') Is the most ideal to use a form having a flexible elastic deformation force by the inner space portion as in the general form, the gaskets 60, 60' is the inner glass panel (to be disposed toward the room) 50 ') to be in close contact with.

Accordingly, as shown in FIGS. 5 and 6, the first chassis member 10 and the second chassis member 20 are connected to each other through the heat insulating material 40, and the second chassis member 20 and the finishing member are connected to each other. 30 is installed in the chassis assembly at a predetermined interval with respect to the wall for forming the curtain wall of the chassis assembly made by fixing each other by the engaging force of the fitting protrusions 22, 22 'and the fitting grooves 31, 31'. After the glass panel 50 is sequentially inserted in the transverse direction with respect to the outer insertion grooves 11 and 11 ′ of the first chassis member 10 in the state, and then caulking through silicon or the like, the inner insertion groove 12 is formed. After inserting another glass panel 50 'to 12' sequentially, the double curtain wall window is completed by bonding and fixing the finishing member 30 and the glass panel 50 'through silicon caulking. It is.

However, it would be common to pre-install the outdoor glass panel 50 and post-construct the glass panel 50 'on the indoor side. In the state where the outdoor glass panel 50 is bonded and silicon caulking is made, When the assembly of the glass panel 50 'on the side and the silicone caulking on the coupling part corresponding to the indoor side are made, the part of the worker's hand does not reach the coupling part on the outer surface of the glass panel 50' on the indoor side. Caulking work using silicon is difficult.

Therefore, the gaskets 60 and 60 'as described above are closely adhered to and compressed on one side of the glass panel 50', thereby completely blocking the gaps between the glass panels 50 ', thereby providing a firm holding force to the glass panel 50'. Of course, the communication of air or noise is blocked so that the soundproofing and insulation effect can be fully exhibited. At this time, in the process of inserting the glass panel 50 ', the backing member made of synthetic resin or rubber is inserted into the exposed part of the opposite side of the gasket 60, 60' by inserting a separate backing member in the form of interference fit. It is forcibly inserted between the 30 and the glass panel 50 'to compress the gaskets 60 and 60' so that the adhesion between the gaskets 60 and 60 'and the glass panel 50' is improved. You can do it.

Here, if the pre-construction is made with respect to the glass panel 50 'on the indoor side, the gaskets 60 and 60' should be inserted into the inner surface of the outer insertion grooves 11 and 11 '. The surface of the glass panel 50 on the outdoor side to be constructed is to be in close contact with the inner portion that the operator's hand does not reach.

Therefore, since the glass panels 50 and 50 'are spaced apart from each other in the double direction toward the outdoor side and the indoor side as described above, in addition to the sound insulation and heat insulation of the glass panels 50 and 50' itself, It is possible to maximize the noise blocking and insulation effect, while maintaining the advantages of the existing curtain wall window, while greatly improving the insulation and sound insulation, which has been pointed out as a problem.

In addition, the heat insulating material 40 is intended to block heat loss due to the excellent thermal conductivity of the first chassis member 10 and the second chassis member 20 which are extruded from a metal material, the effect of the season If the cold or hot indoor and outdoor cold and hot air is conducted through the first chassis member 10 or the second chassis member 20, the hot or cold air is blocked by the heat insulator 40 to prevent further progress. In addition, the cooling and heating effect of the room is not diffused due to disconnection of the cooling air and the heat, and the cooling and heating effect of the indoor is reduced, as well as the low temperature or high temperature of the cold or hot air. As it is conducted through the second chassis member 20 so as not to affect the room, the double curtain wall window according to the present invention serves to further enhance the thermal insulation effect.

In particular, in the above embodiment, the first chassis member 10 and the second chassis member 20 are described as independent components, but as shown in FIG. After two extrusion member 20 is formed integrally, they may be separated from each other to be used separately.

That is, the first chassis member 10 and the second chassis are connected to each other by a connecting portion 23 connecting the locking jaw portion 14 of the first chassis member 10 and the locking jaw portion 21 of the second chassis member 20 to each other. The members 20 can be integrally extruded from each other. At this time, the connection portion 23 is to be formed in the extrusion molding step along the longitudinal direction (15, 15 ').

In such a state, when the connection part 23 is removed by the cutting grooves 15 and 15 ', the first chassis member 10 and the second chassis member 20 are independent components. It will be separated.

Here, the method of separately manufacturing the first chassis member 10 and the second chassis member 20 may be possible, but the first chassis member 10 and the second chassis member are formed by the connection part 23. The reason for integrally extruding the 20 is that it is very economical to integrate and produce two independent components simultaneously through a single extrusion mold, and the first chassis member 10 and the second chassis member 20 can be easily made in the field. Since it can be used to cut and separate, it is intended to benefit the operator in terms of handling and working convenience, such as transport or storage.

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to provide further explanation of the present invention as defined by the appended claims. Examples should be understood.
