The fitting wall 302a extends outwardly by a fastening member 400 passing through the heat insulating material 300 and is brought into close contact with the inner circumferential surface of the fitting projection 101 of the inner frame 100. [

The central part of the partition wall 302 of the heat insulating material 300 is bent in the direction of the inner frame 100 so that the coupling member 400 enters the fitting groove 102 of the inner frame 100 Guide.

The fastening member 400 vertically penetrates the outer frame 100 and the heat insulating material 300 and the distal end thereof is fastened to the inner frame 100.

The fastening member 400 forms a thread 401 on its outer surface.

The thread 401 of the fastening member 400 penetrates the outer frame 200 and the heat insulating material 300 and is inserted into the fastening groove 101a of the fitting projection 101.

The insulating window frame according to the present invention having the above configuration is used as follows.

5 to 6, an inner frame 100 is installed inside a building, and a heat insulating material 300 is inserted in front of the inner frame 100 or is coupled in a sliding manner.

At this time, the fitting protrusion 101 of the inner frame 100 is fitted between the side walls 301 of the heat insulating material 300, and the fitting wall 302a protruding from the partition wall 302 of the heat insulating material 300 So as to enter between the fitting grooves 102.

The locking protrusion 302b formed at the end of the fitting wall 302a is engaged with the locking groove 101a of the fitting protrusion 101 so that the heat insulating material 300 is securely fixed to the front of the inner frame 100 .

Thereafter, the outer frame 200 is positioned at the other end of the heat insulating material 300, and the outer frame 200 is fitted and fixed to the heat insulating material 300 in this state.

At this time, the inner and outer frames 100 and 200 are connected by the heat insulating material 300, and the coupling member 400 is fastened through the center of the outer frame 200 in this state.

The thread 401 of the fastening member 400 passes through the partition wall 302 of the base frame 201 of the outer frame 200 and the heat insulating material 300 and is inserted into the fitting groove of the inner frame 100, (102).

The fastening member 400 is guided by the partition wall 302 bent in the direction of the inner frame 100 and enters the fitting groove 102 of the inner frame 100.

Particularly, the thread 401 of the fastening member 400 which has entered the fitting groove 102 of the inner frame 100 is engaged with the fastening groove 101a of the fitting projection 101, And the inner and outer frames 100 and 200 are securely connected and fixed by the fastening member 400. In addition,

A finishing frame 202 is installed in front of the base frame 201 of the outer frame 200 to prevent rainwater, dust or foreign matter from penetrating the base frame 201 and the fastening member 400.

The gasket 304 is slidably coupled through the sliding groove 303 formed in the side wall 301 of the heat insulating material 300 so that the gasket 304 is exposed to the outside of the sliding groove 303.

At this time, by inserting and fixing the window W through the space between the inner and outer frames 100 and 200, the one side of the window W is adhered to the end of the gasket 304, A curtain wall is formed to enclose a space formed between the window frame and the window W, thereby forming an outer wall of the building.

The outer frame 200 is inserted in front of the heat insulating material 300 and the gasket 304 is slidably coupled to the heat insulating material 300, And the window W is inserted between the inner and outer frames 100 and 200 as an example, the order may be changed depending on the operator.

Referring to FIG. 7, in the case of the heat insulating window frames thus formed, the outer frame 200 receives outdoor heat, and the flow of heat is blocked by the partition wall 302 of the heat insulating material 300, And remains in the space portion 301a located on the outdoor side with respect to the wall 302. [

The inner frame 100 installed inside the building receives the cold air in the room maintained by the air conditioner or the like and the flow of the cool air is blocked by the partition wall 302 of the heat insulating material 300, 302 in the space portion 301a located on the indoor side.

The heat is circulated in the space 301a located on the side of the outer frame 200 with the partition wall 302 of the heat insulating material 300 interposed therebetween and is left on the side of the inner frame 100 The outdoor air is prevented from flowing into the inside of the building by being blocked by the partition wall 302 and the cold air by the circulation of the cold air in the positioned space 301a, And is prevented from being released to the outside of the building.

The outdoor heat that flows into the space between the heat insulating material 300 and the window W through the surface of the outer frame 200 and the window W is a space between the heat insulating material 300 and the window W And is left in the space located on the outdoor side with respect to the gasket (304).

The cold air in the room flowing into the space between the heat insulating material 300 and the window W through the surface of the inner frame 100 and the window W is cooled by the space between the heat insulating material 300 and the window W The gasket 304 is blocked by the partitioning gasket 304 and remains in the space located on the indoor side with respect to the gasket 304.

The heat that flows into the space between the window W and the heat insulating material 300 through the outer frame 200 is blocked by the gasket 304 and the cold air remaining in the indoor space, And the indoor cold air is blocked by the gasket 304 and the remaining heat in the outdoor space, and is prevented from being discharged outside the building.

The gasket 304 prevents the window W from approaching the heat insulating material 300 by a predetermined distance or more and prevents the heat insulating material 300 from being damaged or deformed by the window W .

On the other hand, in the winter season, by the same principle as described above, outdoor cool air is prevented from flowing into the inside of the building, and the heat inside the room is prevented from being released to the outside of the building.

The end of the fastening member 400 passing through the outer frame 200 and the heat insulating material 300 is inserted and fixed in the fitting groove 102 of the inner frame 100 as described above so that the gap between the heat insulating material 300 and the inner frame 100 The structure for strengthening the clamping force is constructed such that the inner and outer frames 100 and 200 are connected by the fastening member 400 which is inserted and fixed in the fitting groove 102 through the heat insulating material 300 and the outer frame 200, And the heat insulating material 300 is firmly fixed between the inner and outer frames 100 and 200 by the fastening member 400 so that the heat insulating material 300 is not deformed by the inner and outer frames 100 and 200, The heat insulating part 300 passes through the fastening member 400 to the partition wall 302 so that the heat insulating material 300 is not cracked and the heat insulating effect of the heat insulating part 300 is maintained by the crack prevention, 200 and the heat insulating material 300 is fixed to the fitting groove 102 of the inner frame 100 The simple construction reduces the working time, and the simple structure makes it easy to tighten, thus improving the reliability of the product.

The above description is only one embodiment for carrying out the heat insulating window frame according to the present invention. The present invention is not limited to the above-mentioned embodiment, but is deviated from the subject matter of the present invention as claimed in the claims of utility model registration It will be understood by those skilled in the art that the present invention has the technical spirit of the present invention to the extent that various modifications can be made.
