Description

Technical Field [0001] The present invention relates to a glass pane having improved insulation and assemblability and a method of manufacturing the same,

[0001] The present invention relates to a mirror-type windowpane with improved heat insulation and assemblability for cooling and heating, and a method of manufacturing the same. More particularly, the present invention relates to a windowpane windowpane for reducing heat loss and noise through a windowpane, The present invention also relates to a method of manufacturing the same and a method of manufacturing the same.

A window is a window or a door or a frame, which isolates the room from the outside to prevent the wind from entering the room, or is used for indoor ventilation. The structure is basically a window frame Door frame) and a windowpane (or door) mounted inside the doorpane.

The window can be distinguished by the opening type or the non-opening type or the fixed type according to the opening manner. Also, according to the number of the window (or door) installed in one window frame (or door frame), the window may be distinguished by a window, a double window, a triple window or a broken window, And the three single-pane glasses are separated from each other by injecting an inert gas into the space portion between them, or by forming a space layer to increase the heat insulating and sound-insulating performance, respectively. The inert gas is injected into the space portion therebetween, (Or three-layered) glass with improved insulation and sound insulation. There are various other categories.

In recent years, materials such as aluminum and polyvinyl chloride (PVC) have been widely used as materials for forming window frames (door frames) and window frames (door frames). Aluminum is usually applied to veranda or high-rise buildings because it does not cause oxidation, such as decay, deformation or iron like wood. However, aluminum has a disadvantage in that the heat insulating effect is deteriorated due to the high thermal conductivity and the sound insulation and insulation effect is deteriorated due to generation of clearance at the assembled part during long-term use due to thermal deformation. In contrast, synthetic resin is superior to aluminum in its insulation effect, and in most cases it is installed at the boundary between living room and veranda. In this case, aluminum and synthetic resin construction windows are exemplified as aluminum, veranda and synthetic resin are not always installed at the boundary between the verandah and the living room.

Meanwhile, since July 1, 2012, the energy efficiency rating system that has been applied to household appliances and automobiles has been implemented in Changwon, and by improving the structure of window frames and window panels in various ways to improve airtightness and insulation performance, Is being developed.

The most significant part of the effort is to replace the glass with multiple glass, to insulate the metal frame with synthetic resin material to block the heat transfer of the outside air through the window frame frame, to insulate the composite frame by insulation, A method of filling the air bag, airtightness between the window frame and the window frame, and a method of providing a side airbag plate or a horizontal airbag plate for heat insulation.

In order to increase energy efficiency efficiency in the conventional window glass structure, the airtightness and the thermal insulation structure are mainly improved on the horizontal frame side of the window frame. Because the roller is installed on the lower part of the window for the left and right sliding, the window without the roller is separated from the upper part of the rail of the window by a certain distance and the space is formed to be vulnerable to airtightness and insulation There is a structural problem.

Another reason is that in order to install a window on the window frame of the shutter window, normally, the window is opened at an angle and the window is opened. Then, the upper part of the window is coupled to the rail at the upper part of the window frame, When the lower side of the window is located on the lower rail of the window frame, the window is lowered on the rail and the installation is completed. In such a case, there is a gap between the window pane and the window frame due to the height of the rail protruded from the window frame. There is a structural problem.

Due to the structural problems of these window frames and windows, most airtight and adiabatic structural improvements are centered on the window frames and window sill and upper structure.

When assembling the vertical window frames and the horizontal window frames, the window frames constituting the front window windows are formed by diagonally cutting the edges of most of the individual window frames in a diagonal angle or machining them at right angles, and then connecting the corner connectors to the vertical window frames and the horizontal window frames And then fixed by a plurality of pieces to be connected to each other.

As a conventional technique having such a structure, Korean Utility Model Registration No. 20-0186942 (Joiner for assembling P, V, city windows and window frames), Korea Utility Model Registration No. 20-0302212 Korean Patent Registration No. 10-0804749 (Anti-shake device with anti-wind pressure function), Korea Patent No. 10-0776340 (Anti-edge device for edge frame), Korea Patent No. 10-0723448 Frame connector) and the like are disclosed.

However, in the case of a windowpane made of a metal material in particular, the windowpane structure is hollow so that the outer space is thermally conductive to be vulnerable to thermal insulation, and convection through the inner space is conducted. There is also a problem that it has a structure susceptible to insulation.

In addition, since the corner connector is inserted into the inner space between the vertical window frame and the horizontal window frame and then fixed with a piece such as a plurality of bolts or screws, a lot of air is supplied during the assembly, And the durability of the window is deteriorated.

Korean Registered Utility Model No. 20-0186942 (Apr. 12, 2000) Korean Patent Registration No. 10-0723448 (May 23, 2007) Korean Patent Registration No. 10-0804749 (Feb. 12, 2008) Korean Patent Registration No. 10-0776340 (2007.07.07)

Front, flat, bottom, left An exemplary view showing a side and a right side.

As shown in FIG. 1, the left and right sliding windows 1 according to one embodiment of the present invention are basically provided with rollers corresponding to the rails at the lower portion of each mirror window so as to slide left and right along the respective rails provided inside the window frame do.

Specifically, the mirror-type window 1 according to the present invention has a structure in which a corner connector 20 in which a horizontal and vertical window frame 1, in which a heat insulating material for cooling and heating is filled in the inner space portion, .

In addition, if necessary, it is possible to use a piece at a corner connector to combine the corner connector and the horizontal window frame or the vertical window frame filled with the heat insulating material for cooling and heating to strengthen the fastening force.

The frame structures of the horizontal strip frames and the vertical strip frames have the same structure. Hereinafter, the horizontal strip frame will be described for convenience of explanation.

In order to reduce or prevent heat conduction through the horizontal window frame 10 made of a metal and air convection through the internal space, the internal space is divided into a first heat insulating part 11 formed by foaming a hard first heat insulating material 112, And a second heat insulating portion 12 formed by foaming the soft second heat insulating material 122 to constitute a multiple insulation.

The first heat insulator 112 and the second heat insulator 122 may be any heat insulator made of a synthetic resin material capable of blocking heat conduction. For example, foamed polyurethane can be used.

The horizontal strip frame 10 includes a first heat insulating frame 111 protruding and bent toward one side (lower side relative to the horizontal strip frame) of the side frames 10 when the strip frame 10 is extruded to form the first thermal insulating part 11, The aluminum material temporary mold 113 is extruded together with the aluminum material temporary foam 113 so that the hard polyurethane as the first heat insulating material 112 is foamed in the inner space of the first heat insulating part frame 111, The aluminum material temporary die 113, which is easily extruded and formed at both ends, is cut to insulate the corresponding portion so that the interior is insulated by the filled first heat insulator 112, and the temporary die 113 is cut So that the heat conduction through the metal first heat insulating part frame 111 is blocked.

At this time, a foamed soft second heat insulator 122 is supported on the outer portion of the first heat insulating frame 111 protruding into the inner space of the window frame 10 and surrounding the hard first heat insulator 112 A plurality of support protrusions 114 are arranged and protruded at regular intervals.

The protruding shape of the support protrusion 114 can form various protrusion structures in a shape that supports the second heat insulator 122. It can be extruded into various shapes such as a right-angle column, a hook shape, and an arrow shape.

The reason why the first heat insulator 112 is foamed with hard polyurethane is to prevent the heat conduction through the aluminum material and to reinforce the rigidity of the first heat insulating frame 111 including the open section.

The horizontal strip frame 10 is formed by bending and protruding from the other side (upper side with respect to the horizontal strip frame) to the space portion during the extrusion of the strip frame 10 to form the second thermal insulation part 12, And a pair of second heat insulating part frames 121 having support cover fastening grooves 123 are formed on the inner end parts of the inner side to fasten the support cover 13.

The support cover 13 fastened to the support cover engaging groove 123 is a synthetic resin material having a bent end at both ends, and is used as a mold when the second heat insulator 122 is foamed.

The cross section of the support cover 13 according to one embodiment may be made of a length material having a 'C' shaped cross section. At both ends of the support cover 13, there is formed a fastening protrusion 131 which has a shape corresponding to the shape of each of the support cover fastening grooves 123, and which is inserted into the cover fastening groove,

The support cover 13 is made of a hard synthetic resin material such as polyamide and has a stiffness of about a hill. Therefore, even if the secondary insulation is foamed, it can withstand the expansion pressure sufficiently. The support cover 13 is made up of a synthetic resin support frame 13 having different heights in consideration of the height of the rail formed on the lower frame or the upper frame of the window frame to be installed and the size of the roller provided below the window frame 10 Can be selected and concluded.

When the support cover 13 serving as the mold and the support frame is fastened, the second insulation member 122 and the second insulation member 122 are inserted into the inner space formed by the second insulation frame 121, the support cover 13, Unlike the conventional window frame 10, when the soft polyurethane is foamed and then the second insulation 122 is cured, the interior is filled with the second insulation 122 rather than the air layer to block the heat conduction due to air convection, .

At this time, the support cover 13 is configured to support the soft second heat insulator 122 by forming a plurality of support protrusions 132 protruding into the inner space of the screen frame 10. The shape of the protruding support protrusions 132 can form various protruding structures in a shape that supports the second heat insulating member 122. It can be extruded into various shapes such as a right-angle column, a hook shape, and an arrow shape.

As described above, the horizontal and vertical window frames 10 (see FIG. 1), which is composed of the first thermal insulating part 11 formed with the first thermal insulating material 112 expanded in the inner space of the window frame and the second thermal insulating part 12 formed by foaming the second thermal insulating material 122 Are assembled by corner fittings 20 installed at the corner portions and inserted into the first and second heat insulating materials 112 and 122 to complete a window.

The corner connector 20 is inserted into and bonded to the second insulation material 122 after filling in the horizontal and vertical window frames 10 during assembly. When the corner connector 20 is inserted into the fully cured second insulation 122, a strong fastening force is provided. In order to enhance the fastening force of the corner connector 20, a minimum number of pieces can be used to supplement the horizontal or vertical frame at the corner connector 20.

The corner connector 20 is configured to be bi-directionally coupled to the horizontal and vertical web 10 at the corners of the 'A' cross-sectional structure that are tangent to the horizontal web frame and the vertical web frame.

Specifically, the corner connector 20 includes a pair of horizontal insertion ports 202 and a pair of vertical insertion ports 203 spaced at a predetermined interval by a gap member 201 having a biconcave cross-sectional structure. The pair of horizontal insertion openings 202 and the pair of vertical insertion openings 203 are inserted into the second thermal insulation material 122 located in the horizontal direction and the vertical direction, respectively.

The pair of horizontal insertion ports 202 or the vertical insertion ports 203 can be inserted into the space between the side panels 10 and the side surfaces of the second insulation frame 121 and the support cover 13, And is inserted into the second heat insulating material 122 filled in the corresponding space part, respectively, and is then fastened.

The horizontal insertion port 202 or each vertical insertion port 203 is formed with a heat insulation retaining groove 204 opened toward the horizontal reeling frame or the vertical reeling frame and the inner surface of the heat insulating retaining groove 204 is provided with a plurality of locking projections (205) are arranged at regular intervals.

Since the shape of the locking protrusion 205 protruding from the space portion where the second thermal insulator 122 is located when the horizontal insertion port 202 and the vertical insertion port 203 are inserted into the second insulation material is not easily lost And serves as a stopper for providing a strong fastening force.

The shape of the latching protrusion 205 is formed so as to have a slanting shape so as to easily enter the horizontal inserting hole 202 or the vertical inserting hole 203 into the insulator catching groove 204 when inserting the vertical inserting hole 203 into the second insulating material 122, It has a shape machined at right angles to avoid falling out.
