Description

Heat insulation frame for windows

More specifically, the present invention relates to a heat insulating frame for a window, and more particularly, to a heat insulating frame for a window filled with a foam insulating material in a frame of a metal window including aluminum, molding the transferring member, uniformly applying the foaming heat insulating material from the outside, To a heat insulating frame for a window which is uniformly filled with a heat insulating material.

A window is a window and a door which isolates the room from the outside and blocks the wind. The window is used for ventilation of the room or for the ventilation of the room. The structure is fixed to the window frame (or door frame) (Or door) that is mounted so as to be mounted.

On the other hand, Changhee recently enforced the energy efficiency rating system that has been applied to household appliances and automobiles since July 1, 2012. This is due to the fact that about 40% of the building energy is being counted through the window, Labeling of consumption efficiency grade was attached. The window manufactured according to the window energy efficiency rating system is divided into classes 1 to 5 according to the efficiency of energy consumption, and labels are displayed so that the consumer can easily distinguish the energy saving window and purchase the product, Or products that are below minimum efficiency standards are prohibited from manufacturing and selling.

Because of this window energy efficiency rating system, window makers are currently conducting a lot of research to obtain window rating with high efficiency of heat conduction rate and confidentiality.

Conventionally, wood is widely used as a frame material constituting window frames, but recently, a metal material such as aluminum or a synthetic resin material such as polyvinyl chloride (PVC) has been extensively used.

Synthetic resin window frames are superior to aluminum in their insulation effect and are usually installed at the boundary between living room and veranda.

Aluminum window frames are usually applied to verandas because they do not cause oxidation, such as decay, deformation or iron metal, which are generated from wood materials.

On the other hand, the aluminum has a low thermal insulation effect due to its high thermal conductivity, and has a structural disadvantage in that sound insulation and insulation are deteriorated due to generation of clearance at an assembled part during long-term use due to thermal deformation. In recent years, An aluminum frame improved in heat insulation performance is manufactured by separating the aluminum frames from each other, forming a heat insulating frame of a distance therebetween, or filling a space with an insulating material to prevent heat conduction through the metal material or the space.

As for the structure and manufacturing method of the aluminum frame improved in heat insulating capability,

First, when extruding an aluminum frame, a certain frame section is formed into a frame acting as a mold, and then the foam insulation is injected into the space of the aluminum frame using a gun for injecting the foam insulation, and then expanded. Then, when the foam insulation is dried, There is a method in which a temporarily formed aluminum frame is removed and a space between the spaced apart aluminum frames is filled with a foamed heat insulating material.

Another method is to form a shape to be joined to the aluminum frame at the time of extrusion and then to insert or inserting a heat insulating material serving as a frame thereon. Then, using this heat insulating material as a mold, There is a method in which a foamed heat insulating material is inflated and inflated to place the heat insulating material frame between the aluminum frames and a foamed heat insulating material is filled in the space formed by the frame.

However, due to the difference in pressure or the length of the frame during the injection of the foamed insulating material, the foamed insulating material is not uniformly charged when the foamed insulation is expanded in the inner space, It has a structural problem that it does not provide a uniform heat insulation power as a whole because the space is filled to increase the heat insulation power, but in some sections, the unexpectedly annular space is filled with the heat insulation material.

The reason for this is that there is no method for confirming whether a foamed insulating material injected into a space inside a frame is uniformly injected and applied by a manufacturing method of injecting a pressure set in one direction to the other by using a gun provided with a nozzle Because.

Therefore, the aluminum frame for a window manufactured by the conventional method described above can be confirmed by removing an aluminum frame temporarily acting as a mold between aluminum frames after expansion of the foam insulating material, or after the aluminum frame is cut for sampling, It is difficult to reduce the generation of defective products in the manufacturing process and it is difficult to expect a stable yield of the good product.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

1 is a sectional view showing a heat insulating frame according to an embodiment of the present invention.

As shown in the drawings, the frame used in the present invention is a metal frame used for window frames such as a sliding door, a sliding door, a casement door, and a curtain wall, preferably an aluminum frame. In order to prevent thermal degradation, And a composite frame structure in which a part of the frame is combined with a heat insulating frame made of a synthetic resin material.

In addition, a conveying member is provided in the inner space formed by the aluminum frame and the heat insulating frame. The transferring member is formed by molding a paper material or a synthetic resin material including PVC into a desired shape, and then pulling the transfer material into a space inside the frame.

The forming of the conveying member is preferably performed by forming two guide grooves so that the outer sides of the guide grooves are bent and formed to be perpendicular or inclined upward. The reason for this molding is that the first purpose is to load the foamed heat insulating material in a liquid state so that the foamed heat insulating material does not flow to the surroundings when the foamed heat insulating material is applied and the second purpose is to serve as a kind of skeleton material in the inside of the metal material frame, So as to stably support the foamed insulating material.

When using a paper material, the transferring member may be coated with a water repellent agent or oil to prevent intrusion of moisture as needed, thereby increasing durability.

Further, if necessary, at least one surface of which roughness has been processed may be used in order to increase the contact bonding force with the foam insulating material.

The space excluding the transfer member installed in the inner space of the frame is filled with the foam insulating material. The foaming and heat insulating material is applied to the conveying member from outside of the aluminum frame continuously in a line shape, and the conveying member is pulled from the other side of the frame to be conveyed to the inside of the frame to be expanded so that the space inside the frame can be uniformly filled do. The amount of the foamed thermal insulation material to be used at this time is such that at least the amount of the foamed insulation material used to fill the inner space at the time of expansion is applied to the conveying member.

2 is a cross-sectional view showing a heat insulating frame according to another embodiment of the present invention.

As shown in the drawings, the metal frame for a window according to another embodiment of the present invention is formed by transferring a transfer member to an inner space to separate the aluminum frame shown in FIG. 1 when the inner space is filled, The present invention can be applied to a space made up of only a metal frame.

At this time, if the installation position of the metal frame is rotated, the conveying member can be positioned on the frame surface in any direction of the upper, lower, right, and left frames in the space portion.

When the foamed heat insulating material is uniformly charged into the inner space of the frame, the convection phenomenon generated through the inner space formed of the air layer is blocked, thereby enhancing the overall heat insulating capability of the window frame. For the reference, the air layer generally has a thermal insulation effect. However, when the surroundings are all made of a metal frame, the convection phenomenon of the air occupying the inner space part occurs due to the temperature difference between the frame and the inner air layer during the heat conduction through the metal material. .

FIG. 8 is an exemplary view showing a foamed thermal insulating material application unit according to an embodiment. FIG.

As shown in the figure, the apparatus for manufacturing a metal frame for a window according to the present invention includes a mounting unit 100, a groove processing roller unit 200, a primary forming unit 300, a secondary forming unit 400, 500, a coating unit 600, a pulling unit 700, and a deck 800 in which the respective devices are installed.

The mounting portion 100 includes a rotary shaft 120 which is axially coupled between the side supports 110 so that the unformed transfer member is loosely supplied for molding by means of winding the plate-shaped transfer member 1 in a roll shape So that the conveying member wound around the conveying member is supplied in one direction. Needless to say, the rotation shaft is not shown but can be detachably mounted to mount a new transfer member and can be provided with a stopper that can prevent the removal of the transfer member.

The grooving roller unit 200 is a means for pressing the upper surface of the unformed transfer member 1 during conveyance to form the two guide grooves 11. [ To this end, the forming roller 210 located at the upper portion and the supporting roller 220 located at the lower portion are configured so as to be axially coupled to the both side supports 230, respectively. Two shaping protrusions 211 are formed in the shaping roller around the shaping roller. When the shaping roller 211 is fed through the space between the shaping roller and the support roller, a shaping protrusion 211 protruding from the shaping roller is formed on the upper surface So that the guide groove 11 is formed.

It is preferable that the forming protrusion 211 formed on the forming roller is formed to have a "? (Triangular)" cross-sectional shape so as to bend the feeding member in an inclined angle or a right angle form in the primary or secondary forming part. When the triangular pyramid is machined into the triangular pyramid shape, when the conveying member is pressed to form the guide groove due to the angle formed by the triangular pyramid, the inclination angle or the right angle bending occurs well when the conveying member is folded.

The forming roller and the supporting roller are spaced upward from the upper surface of the deck at a predetermined distance, thereby providing a constant tension to the conveying member. For this purpose, it is preferable that the conveying member 1, which is unwound from the mounting portion 100, is configured to be pulled up at an inclination angle so as to ascend from the lower side of the elevating portion.

The primary forming unit 300 is a means for bending both ends of two guide grooves 11 formed on the conveying member during conveyance at a first inclined angle. To this end, a first upper molded member 310 having a structure in which the two guide grooves are formed at an obliquely bent part and protruding downward, and a second upper molded member 310 having a shape of a first upper molded member And a first molding groove 330 provided between the first upper molding member and the first lower molding member so as to form a gap between the first molding member 330 and the first lower molding member 320, So as to be bent and formed. At this time, the first forming grooves process the first upper forming member 310 and the first lower forming member 320 at angles that are not bent at a right angle. This is because, when the flat plate-shaped transfer member is bent and formed in a rectangular shape from the beginning, it can not be smoothly formed and transferred due to a sudden change in shape, or the transfer member may be wrinkled or broken.

Accordingly, the first upper molded member 310 has a shape becoming narrower toward the lower portion, and the first lower molded member 320 has a shape widened toward the upper portion. The first upper molded member 310 is welded or bolted to one side of the upper surface of the first lower molded member 320 at one end thereof to be integrated. The first upper molded member 310 and the first lower molded member 320 may be made of metal or synthetic resin.

With the above-described construction, the conveying member enters from the front through the first forming grooves 330, is folded at a predetermined angle and is molded and discharged through the rear.

At this time, at the time of setting the manufacturing apparatus of the present invention, one end of the first forming groove 330 is opened in order to facilitate insertion of the transferring member. For this, the first upper forming member 310 is configured not to completely cover the upper portion of the first lower forming member 320.

The secondary forming part 400 is a means for bending both side ends of the two guide grooves 11 formed in the primary molded conveying member at a second angle. To this end, a second upper molded member 410 having a structure bent at right angles at the portion where the two guide grooves are formed and protruding downward, and a second lower portion formed with grooves corresponding to the second upper molded member, And a second molding groove 430 for transferring the transfer member and forming a right angle bend molding are formed in the gap between the second upper molding member and the second lower molding member. At this time, the second forming grooves process the second upper forming member 410 and the second lower forming member 420 so as to be bent at a right angle. The second upper molded member 410 and the second lower molded member 420 may be made of metal or synthetic resin.

With the above-described configuration, the conveying member enters from the front through the second forming groove 430, is folded in a right angle, and is discharged through the rear part.

At this time, at the time of setting the manufacturing apparatus of the present invention, one end of the second forming groove 430 is opened in order to facilitate insertion of the transferring member. For this, the second upper molded member 410 is configured not to completely cover the upper portion of the second lower molded member 420.

The reason why the transfer member is formed by passing through the primary molding part 300 and the secondary molding part 400 as described above is to load the foamed heat insulating material in a liquid state so that the foaming heat insulating material in a liquid state does not flow to the periphery The second purpose is to support foam insulation in vertical or horizontal direction by acting as a kind of skeleton during expansion in the metal frame.

The conveying roller unit 500 is a unit configured to once again mold the formed shape of the formed conveying member and to convey the formed conveying member while maintaining the formed shape. By this conveying roller portion, a conveying member passing through the fixing portion, the groove forming roller portion, the primary forming portion and the secondary forming portion is conveyed.

To this end, the conveying roller unit 500 is constituted by a form roller 510 installed at the upper part and a driving roller 520 installed at the lower part. Two grooves 511 are formed along the periphery of the mold rollers so that the formed transfer member can pass through the mold roller so that the bent ends of the transfer member are passed through during the rotation.

When the first conveying member is set, the folded portions of both side ends of the conveying member are inserted into the grooves 511 formed in the mold roller 510, and then the lower surface of the conveying member is pressed downward, (540) provided on a support member (530) provided on the upper surface of the deck (800) so that the driving force is transmitted smoothly. The form roller adjusting means is configured to adjust the vertical position of the form rollers when the form rollers are rotated by forming a thread in a circumferential section and screwing them together with threads formed on the both-end bearing member or the mount member to which the form roller is engaged. That is, when the form roller adjusting means passing through the support member is rotated in the one direction or the other direction in a state in which it is rotated so as not to move up and down, only the threaded form roller is lowered or raised while the contact pressure between the transfer member and the drive roller .

The driving roller 520 is configured to rotate by a motor 550 which is axially coupled to one end.

The application unit 600 is a means for applying the foamed thermal insulating liquid to the upper surface of the conveying member in the form of a line in the form of a line. The coating unit includes a heat insulating liquid storage unit 610 having a nozzle 640 formed at a lower portion thereof, a first supply port 620 connected to the heat insulating liquid storage unit 610 to supply a heat insulating liquid stored in the storage tank, And a supply port 630. The foam insulation material supplied to the first supply port 620 and the second supply port 630 may be composed of the same or different components. In the case of the same foamed insulation material liquid, one-component foamed insulation material is applied, and in the case of different insulation material liquid, it becomes a two-liquid foamed insulation material mixed in the insulation liquid storage part 610. As the foaming heat insulating material to be used, a known foaming heat insulating material for heat insulation may be used, so that the specific constitution will be omitted. For example, it may be a foamed polyurethane liquid.

The pulling portion 700 is a means for pulling and positioning a conveying member coated with a foamed heat insulating material into a frame made of a metal frame 2 and a heat insulating frame 3 or a frame made of only a metal frame.

To this end, a grasping means 710 for holding the leading end of the conveying member, a pulling line 720 connected to the grasping means, a reel 730 on which the pulling line is wound, And a reel motor 740 which is shaft-coupled to pull or pull the pulled cord.

Also, it is preferable that a tow line guide or hole (not shown) 801 is formed on the deck so as to guide the pulling line so that the feeding member can be pulled into the frame while stably fixing the position when pulling the pulling line.

When the conveying member molded inside the frame is positioned through the above-described manufacturing apparatus, the foam insulating liquid applied with a uniform amount in the form of a line expands, and the space inside the frame is uniformly formed as shown in FIGS. 1 and 2 Charging.

11 is a process flow chart showing a method of manufacturing a heat insulating frame for a window according to an embodiment of the present invention. Hereinafter, a manufacturing method using the manufacturing apparatus described with reference to Figs. 3 to 10 will be described.

The manufacturing method of the present invention comprises: a step (S100) of preparing and preparing a plate-shaped transferring member (1) largely unformed in a mounting portion (100);

A step (S200) of forming two guide grooves on the surface by passing the unformed plate-shaped conveying member through the grooving roller unit 200;

(S300) of firstly bending the side end portions of the guide grooves at a predetermined angle while passing the conveying member having the guide grooves formed thereon through the primary forming portion 300;

(S400) of forming a second bent portion at a side edge of each guide groove while passing the first bent-formed transfer member through the second forming portion 400;

A transfer step S500 of supplying the transfer member 500 in one direction while maintaining the shape of the secondarily bent transfer member through the transfer roller unit 500;

(S600) uniformly applying the foamed insulating material liquid to the upper surface of the conveying member that is fed and formed by bending and molding through the applying unit 600;

A step (S700) of gripping the folded molded transfer member having the foamed heat insulating material applied thereon by pulling and pulling the folded molded transfer member into the frame;

And then expanding the foam insulating material applied to the transfer member for a predetermined period of time to uniformly fill the space inside the frame (S800), thereby manufacturing a heat insulating frame for a window.

Step S100 is a step of preparing a plate-shaped transferring member wound in a roll shape. The transferring member is made of paper or a synthetic resin material such as PVC. When pressure is applied, the transferring member has a thickness and hardness Is preferably used.

In step S200, the upper surface of the unformed transfer member 1 being conveyed is pressed to form two guide grooves 11 by using the groove processing roller unit 200. To this end, the groove forming roller unit 200 The two forming protrusions 211 formed on the upper forming roller 210 press the upper surface of the transfer member while rotating to form the grooves.

At the same time, when the upper forming roller rotates, the supporting roller 220 is rotated at the same speed so that the lower conveying member is not scratched or crumpled by friction.

At this time, the forming roller and the supporting roller are not rotated by the self-power but the driving roller 520 interlocked by the rotation of the driving motor provided to the conveying roller portion 500 and the form roller pressing the upper portion of the driving roller rotate When the conveying member is pulled by the pulling force, it rotates.

In the step of forming the guide grooves, the grooves corresponding to the shapes of the molding protrusions 211 formed on the periphery are formed. Preferably, the guide grooves are formed to have a curved cross section of " DELTA (triangular pyramid shape) " So that it is preferable.

In operation S300, the first upper forming member 310 and the second lower forming member 320 are formed in a shape of being bent obliquely at the portion where the two guide grooves are formed, The first forming part 300 provided with a clearance between the first upper forming part and the first lower forming part 330 passes through a conveying member having a guide groove formed therein, So as to be bent. The reason for forming the inclined angle at an angle rather than bending at a right angle is that when the plate-shaped conveying member is bent and formed into a rectangular shape from the beginning, it is difficult to smoothly form and convey due to a rapid change in shape or the conveying member is wrinkled or broken It is because.

In the step S400, the second upper molding member 410 and the second lower molding member 420 have a structure in which the two guide grooves are bent at right angles, and the second upper molding member and the second lower molding member 420, The second molding part 400 having the second molding groove 430 provided by the clearance between the members is formed, and the molding is formed so that the carrying member is bent in a right angle through the guide groove part by passing through the carrying member formed with the guide groove. When formed at right angles, the foaming heat insulating material in a liquid state can be stacked so that the foaming heat insulating material does not flow to the surroundings when the foaming heat insulating material is applied, and the foaming insulating material can be stably supported in the vertical or horizontal direction .

The step S500 includes a form roller 510 having two grooves 511 formed thereon and a drive roller 520 provided at a lower portion of the mold roller 510. The mold roller 510, into which the bent- The driving force is applied to the conveying member in contact with the driving roller so that the rotational force of the driving roller is applied to the conveying member to convey the conveying member connected from the mounting portion to the second forming portion.

At this time, a form roller adjusting means 540 is provided for raising and lowering the form rollers, wherein the form roller adjusting means includes a thread formed in the circumferential section and formed in the both-end bearing member or the mounting member, So that the top and bottom positions of the form roller can be adjusted during the rotation.

In step S600, a heat insulating material solution reservoir 610 having a nozzle 640 formed thereon and a first supply port 620 connected to the heat insulating solution reservoir 610 to supply the insulator solution stored in the storage tank, A step of applying a uniform amount of the foam insulating material liquid through the application unit 600 composed of the supply port 630 and the step of discharging the stored foamed heat insulating material liquid at a uniform pressure downward from the upper side, And is applied in a line shape. At this time, the pressure can be controlled by taking a method of supplying the heat insulating material stored in the heat insulating material storage part 610 or by using a separate liquid supply pump or a first supply port 620 and a second supply port 630, The pressure of the liquid transfer pump not shown may be used.

Since the method of dropping downward from the open space is adopted, the application position and amount of the foam insulating material applied to the transfer member can be accurately known before entering the inside of the frame. Therefore, when manufacturing a heat insulating frame for a conventional window, Thereby preventing nonuniform application and expansion occurring when the ink is jetted into the frame. That is, conventionally, the foamed insulating material liquid is unevenly applied to the inside of the frame due to the injection time, the injection pressure, the injection angle, etc. through the gun, and is expanded to cause uneven charging. The present invention has such a step .

In the applying step, the insulator liquid supplied to the first supply port 620 and the second supply port 630 may be composed of the same or different components. In the case of the same heat insulating material liquid, one-component foam insulating material is applied. In the case of different insulating material liquid, the two-liquid foam insulating material mixed in the heat insulating material storage part 610 becomes a heat insulating material. As the foaming heat insulating material to be used, a known foaming heat insulating material for heat insulation may be used, so that the specific constitution will be omitted. For example, it may be a foamed polyurethane liquid.

The step S700 is a step of uniformly moving the conveying member to the inside of the frame by the conveying member coated with the foam insulating liquid. Through the above steps, the transferring member makes a state in which the foam insulating liquid is uniformly applied to the inside of the frame.

To this end, a grasping means 710 for holding the leading end of the conveying member, a pulling line 720 connected to the grasping means, a reel 730 on which the pulling line is wound, And pulls the conveying member at a constant speed by using a pulling portion 700 composed of a reel motor 740 which is shaft-coupled to pull or pull the pulled cord.

The reel motor and the drive motor are configured to provide the same speed to the conveying member by control. If moving at different speeds, the conveying member may be wrinkled or broken.

Further, it is preferable that a pull cord guide or hole 801 is installed or formed on the deck so that the position of the cord can be stably guided at one point when the pull cord is pulled by using the reel motor.

In order to grasp the first conveying member, the first conveying member may be passed through the one side to the inside of the frame and then pulled from the other side to grip the conveying member at the front end.

The frame used herein is a metal frame, that is, a window frame or a frame made of a metal material, that is, an aluminum frame to which a heat insulating frame is coupled between aluminum frames.

It is also possible to apply to a synthetic resin frame such as PVC in order to improve the heat insulation.

If the step S800 is performed, the space inside the frame in which the transfer member coated with the foam insulating liquid is uniformly spreads the foam insulating material uniformly. Then, when dried, a high-quality heat insulating frame for windows with stable heat insulating efficiency is produced.

The frame may be manufactured by supplying a necessary length from the beginning, or a frame of a certain standard may be cut to a length required for installation after supply.

In addition, the expansion time and the firing rate vary depending on the type and application amount of the foamed insulation used, so that it may be used in consideration of the required heat insulation.

In addition, after manufacturing the heat insulating frame for the primary window, if necessary, the step S100 may be followed by filling the space of the adjacent frame with the foam insulating material solution through the step S800.
