In order to support the window W, a reinforcing structure is formed to prevent the metal heat-insulating window frame 1 from being warped or deformed by the load of the window W even during long-term use of the metal heat-insulating window frame 1. [

The metal heat insulating window frame 1 according to the present invention is basically composed of an outer frame 10 made of stainless steel and divided into an inner frame member 10A and an outer frame member 10B, An aluminum supporting member 20 (20), which is disposed on the frame member 10B and includes an inner supporting member 20A and an outer supporting member 20B for supporting the inner frame member 10A and the outer frame member 10B, And a heat insulating member 30 made of polyamide and disposed between the supporting members 20A and 20B and connecting the supporting members 20A and 20B in a heat insulating structure.

Here, the outer frame 10 may be made of various materials such as stainless steel or aluminum. However, in the present invention, the stainless steel plate is bent so as to have high strength, strong corrosion resistance to prevent corrosion due to external factors, .

At this time, the outer frame 10 is divided into an inner frame member 10A and an outer frame member 10B, and each of the frame members is formed into an inner hollow having a shape of a part of which is opened, The window W is coupled between the windows 10A and 10B.

In the present invention, the inner support member 20A and the outer support member 20B are coupled to the inner frame member 10A and the outer frame member 10B, respectively, forming the outer frame 10, The inner frame member 10A and the outer frame member 10B are respectively supported by the outer support member 20A and the outer support member 20B.

The inner support member 20A and the outer support member 20B constituting the support member 20 are made of an aluminum material that can be freely formed through extrusion molding and are formed of a vertical support plate A pair of horizontal support plates 20A-b, 20A-b ', 20B-b and 20B-b' connected to the vertical support plates 20A-20A- a and 20B-a are installed inside the external frame 10 and the horizontal support plates 20A-b, 20A-b ', 20B-b and 20B- And the heat insulating member 30 is installed between a pair of horizontal support plates 20A-b, 20A-b ', 20B-b and 20B-b' formed on the inner support member and the outer support member Lt; / RTI >

As shown in FIG. 3, the vertical support plates 20A-a and 20B-a are formed in an "I" shape so that both ends of the vertical support plates 20a-a and 20B-a come into contact with the upper and lower inner peripheral surfaces of the outer frame 10, When the heat-shielding member 11 is provided to further improve the shape of the heat-shielding member 11, the fitting jaws 20A-f and 20B-f are protruded from the end portion of the "I" .

Therefore, since the upper and lower portions of the outer frame 10 are supported by the vertical supporting plates 20A-20B-a of the supporting member, the load or external force of the window applied to the outer frame 10 is dispersed, There is an effect of preventing damage of the external frame.

Therefore, the inner supporting member 20A and the outer supporting member 20B are connected to each other through the coupling pieces 20A-c, 20A-c ', 20B-c and 20B- Since the heat conduction between the room and the hollow portion of the external frame 10 disposed outside the room is blocked through the heat insulating member 30, the heat insulating property can be ensured.

Since the heat insulating member 30 is made of a polyamide material as described above, the heat insulating member 30 can be formed in a large quantity by injection molding or extrusion molding in advance. The horizontal supporting plate 20 20B-c ', 20B-c, and 20B-c' formed at the end portions of the first, second, and third end portions 20A-20A-b, 20A-b ' , A heat insulating structure of the metal heat insulating window can be formed by a simple operation.

The outer frame 10 is made of stainless steel. The outer frame 10 is formed by bending plate-shaped stainless steel into a simple shape such as a U-shape or a letter shape. Then, the outer frame 10 is fixed to a support member 20, To complete the window frame.

5 to 7 showing another embodiment of the present invention, the external frame 10 and the support member 20 may be combined in different ways.

The basic configuration in this embodiment is the same as that in the first embodiment described above, and the same constituent elements are denoted by the same reference numerals, and redundant description is omitted.

According to the present embodiment, the protrusions 20A-e and 20B-e and the fixing pieces 20A-d and 20B-e are provided on the supporting member 20, as shown in Fig. 5, in the heat insulating window frame 1 having the above- 20B-d).

At this time, the end portions of the inner frame member 10A and the outer frame member 10B are positioned on the horizontal support plates 20A-b, 20A-b ', 20B-b and 20B- 20A-b ', 20B-b, 20B-b').

7, when the inner support member 20A and the outer support member 20B are coupled to the inner frame member 10A and the outer frame member 10B, respectively, E and 20B-e formed on the horizontal support plates 20A-b, 20A-b ', 20B-b and 20B-b' of the support member, the ends of the outer frame member 10A and the outer frame member 10B D and 20B-d formed upright on one side of the horizontal support plates 20A-b, 20A-b ', 20B-b and 20B-b'.

 Thereafter, the fixing pieces 20A-d and 20B-d are pressed and fixed to the upper portions of the inner frame member 10A and the outer frame member 10B, respectively, and the horizontal supporting plates 20A-b, The inner frame member 10A and the outer frame member 10B are bent together by the projections 20A-e and 20B-e formed on the inner frame member 20A-b ', 20B-b and 20B-b'

Therefore, the outer frame 10 can be coupled with the support member 20 without a separate fastening step through a secondary rolling process. Therefore, the outer frame 10 can be easily operated, and the fastening pieces 20A-d and 20B- It is prevented from flowing back and forth since it is fixed to the support member 20, so that the coupling stability can be improved.

Although the outer frame 10 is coupled with the heat insulating member 30 between the inner frame member 10A and the outer frame member 10B, if the temperature difference between the room and the outside is large, the inner frame member 10A, And the heat transfer between the outer frame member 10B and the outer frame member 10B is actively conducted.

In order to prevent this, in the present embodiment, the heat shield member 11 is joined to the inner circumferential surfaces of the inner frame member 10A and the outer frame member 10B, which are divided and configured.

The heat block member 11 is formed of a polyamide material having a low thermal conductivity and is manufactured through injection or extrusion molding. The heat block member 11 is formed to correspond to the inner peripheral surface shape of the inner frame member 10A and the outer frame member 10B, A heat insulating layer made of a polyamide material having a low thermal conductivity is formed on the inner circumferential surfaces of the inner and outer frame members so as to be closely attached to the inner circumferential surfaces of the inner and outer frame members 10A and 10B.

As described above, the fitting jaws 20A-f and 20B-f are protruded from both upper and lower ends of the vertical supporting plates 20A-20B-a and the end portions of the heat- A heat insulating space is formed in the hollow portion of the inner frame member 10A and the outer frame member 10B by the heat shield member 11 coupled to the inner circumferential surface thereof.

Therefore, the temperature of the hollow portion of the inner frame member 10A and the outer frame member 10B is controlled by the heat insulating space formed in the hollow portion of the inner frame member 10A and the outer frame member 10B, The heat conduction phenomenon caused by the temperature difference between the room and the outside is blocked, so that the heat insulating state can be secured.

A heat insulating cover 40 is formed between the inner frame member 10A and the outer frame member 10B.

The heat insulating cover 40 is formed in a "?" Shape so as to contact with the supporting member 20 and the wall of the building. The heat insulating cover 40 is made of polyamide or polyurethane material having a low thermal conductivity.

At this time, the width of the heat insulating cover 40 is equal to the distance between the inner frame member 10A and the outer frame member 10B, and the height is equal to the distance between the support member 20 and the wall of the building desirable.

Therefore, since the heat insulating space is formed between the wall of the building and the metal heat-insulating window frame 1 through the heat-insulating cover 40, the heat is prevented from being transmitted between the wall of the building and the metal heat-insulating window frame 1.

A part of the surface of the heat insulating cover 40 contacting with the building is recessed, and a gasket 41 made of an elastic material is coupled to a depression of the heat insulating cover 40.

At this time, the gasket 41 is made of an elastic material.

Therefore, the metal heat-insulating window frame 1 is in close contact with the opening of the wall through the gasket 41 to thereby block the gap between the wall and the metal heat-insulating window frame 1, 1 can be buffered.

As described above, the metal heat-insulating window frame 1 according to the present invention is such that, when a fire occurs, the fire is firstly blocked by the outer frame 10 made of stainless steel, It is possible to prevent the fire from spreading, and it is not burned by the fire, so that the harmful gas is not discharged.

As shown in Table 1, the experimental results of Experimental Examples 1 to 3 showed that the heat conduction ratios of the experimental specimens were 1.126, 1.127 and 1.128, respectively, but the thermal resistance was 0.89.

In order to obtain the airtightness of the test specimen in accordance with the pressure conditions, the experimental data are shown in Table 2 after the experiments were conducted by setting the pressure difference (Pa) applied to the test specimen at 10, 30, 50 and 100, respectively .

Figure 112015090624977-pat00002

As shown in Table 2, the aeration amount of the test specimen at the pressure difference of 10 to 50 Pa was equal to 0.00 but increased to 0.01 at 100 Pa.

When this experimental value is converted into a graph, it can be seen that the airtightness grade line of the subject is located on the first grade line.

Accordingly, it can be seen that the window according to the present invention is excellent in airtightness.

Figure 112015090624977-pat00003

Table 3 shows the criteria for applying the efficiency efficiency class according to the efficiency management instrument operation regulations. Each grade is given by combining the value of the heat conduction rate and the confidentiality value.

Therefore, the experimental values shown above are summarized as follows: the average value of the heat conduction rate is 1.127, the aeration amount is 0.00, the airtightness grade is 1 grade, and the grade is 2 according to the consumption efficiency grade standard.

Accordingly, the metal heat-insulating window frame according to the present invention is supported by the support member coupled to the outer frame so that the outer frame member and the inner frame member are respectively supported to prevent the inner frame member from being easily deformed by an external force or a load of a window, Of course, by forming the heat-insulating space in which the outer side and the inner side are partitioned by the heat insulating member, the space between the window frame and the window can be more stably shielded and the heat insulating state can be ensured.
