Description

Double window {Double window}

The present invention relates to a double glazing, which is a double glazing, which is excellent in heat insulation performance while maintaining structural performance even under high wind pressure and has improved safety against fire.

The window means various windows or doors installed in the opening to block the inside or outside of the building or to block the space between the inside of the building. Especially, the window system has a remarkably superior performance by using window fittings specially designed compared to the conventional windows, and a window having a complex opening / closing function is called a system window.

Such a system window is used for various buildings requiring opening and closing, for example, as a ventilation passage for air circulation inside and outside of a curtain wall.

However, in general, residential windows are made of polyvinyl chloride (PVC) material having excellent heat insulation and condensation performance. Such PVC windows are excellent in heat insulation performance, but have poor structural performance and therefore are not suitable for applications in high wind pressure areas and have a low melting point It is difficult to apply to an arson window. Aluminum (AL) can be used for the metal frame. Since aluminum has a low strength and ductility, it is easy to work. However, in order to satisfy the structural performance at high wind pressure, But it is difficult to apply to the fire protection window and the thermal conductivity is high.

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing a double window according to an embodiment of the present invention, FIG. 2 is a cross-sectional view showing an outer window in the double window of FIG. 1, .

FIG. 4 is a side sectional view showing the double window of FIG. 1, and FIG. 5 is a bottom view of the thermal expansion slot portion of the double window of FIG.

1 is a perspective view of a window frame 100 according to an embodiment of the present invention; FIG. 2 is a perspective view of a window frame 100 according to an embodiment of the present invention; And an outdoor window 300 disposed on the outdoor side in the outdoor unit.

Here, the outer window 300 may have a handle 321, which is wholly or partly openable and has a separate handle 321, and can be opened or closed by pushing or pulling the handle 321. In addition, the inner window 200 is a sliding door type in which two windows (or doors) are overlapped and can be opened when one window (or door) is opened.

At this time, the outer window 300 may be made of a steel frame to increase the structural performance.

In the conventional outer window 300, PVC or aluminum reinforced internally is used for the frame, and the outer window 300 made of such a material deteriorates the structural performance at high wind pressure.

Accordingly, the outer window 300 disposed on the outdoor side of the double window of the present invention can be made of a steel frame having excellent structural performance because it receives high wind pressure due to strong external wind, It can withstand wind pressure enough to have a stable and robust durability.

In addition, since the melting point of steel (1530 ℃) is much higher than that of AL (660 ℃) and PVC (110 ℃) in the window system of the fire fighting compartment against fire, . Even if the fireproof glass is applied, if the frame can not resist the fire, the fireproof performance of the frame is very important because the fireproof is diffused to the upper and lower layers or the surrounding layers regardless of the glass performance.

Specifically, the outer window 300 may include a fixing part 310 fixed to the window frame 100 and a hinged part 320 rotated by the fixing part 310. That is, the fixing part 310 is a part fixed in position while being in contact with the inner surface of the window frame 100. The hinging part 320 is disposed inside the fixing part 310 and one side is fixed to the hinge 311 And is fixed to the fixing part 310 to be rotated with respect to the fixing part 310.

Here, a heat insulating structure 400 for insulation and airtightness may be formed at the contact portion between the fixing portion 310 and the hinged portion 320. That is, a heat insulating structure 400 for blocking heat exchange between the inside and the outside and a hermetic and watertight function through which air or water can not pass can be formed at the contact portion between the fixing portion 310 and the hinging portion 320 Lt; / RTI >

As shown in FIGS. 2 and 3, the heat insulating structure 400 may include an outer insulating layer 410, an inner insulating layer 420, and an intermediate insulating layer 430, for example, have.

The outer heat insulating layer 410 is disposed on the outer side at the contact portion between the fixing portion 310 and the hinging portion 320 and the inner heat insulating layer 420 is disposed inside the contact portion between the fixing portion 310 and the hinging portion 320 And the intermediate insulating layer 430 is disposed between the outer insulating layer 410 and the inner insulating layer 420.

The inner heat insulating layer 420 and the intermediate heat insulating layer 430 may be arranged such that the outer heat insulating layer 410, the inner heat insulating layer 420, The insulating layer 430 has a structure in which the contact portion of the fixing portion 310 and the contact portion of the hinged portion 320 are in contact with each other. When the hinged portion 320 is opened, the outer heat insulating layer 410 contacts the hinge 311 And the inner heat insulating layer 420 and the intermediate heat insulating layer 430 are separated from each other.

As described above, the heat insulating structure 400 of the external window 300 includes the outer heat insulating layer 410, the inner heat insulating layer 420, and the intermediate heat insulating layer 430 to provide a triple insulation structure, The insulation ability can be increased.

Each of the outer heat insulating layer 410, the inner heat insulating layer 420 and the intermediate heat insulating layer 430 may be formed of a hollow block bar made of a roll-forming steel frame in each of the fixing portion 310 and the hinged portion 320 . At this time, although the block bar is shown only in cross section in the drawing, it may be a long elongated bar shape and a hollow may be formed along the longitudinal direction inside, and this hollow may take a completely closed shape and a partly opened shape .

As shown in the drawing, the outer insulating layer 410 includes a first outer block bar 411 formed on the fixing part 310, a second outer block 411 formed on the hinging part 320, A first inner block bar 421 formed on the fixing portion 310 and a second inner block bar 422 formed on the hinged portion 320 are disposed on the inner heat insulating layer 420 A first intermediate block bar 432 formed on the fixing portion 310 and a second intermediate block 432 bar formed on the hinged portion 320 may be disposed on the intermediate insulating layer 430. [

At this time, the first outer block bar 411, the first intermediate block bar 432, and the first inner block bar 421 are fastened and fixed in order at the fixing part 310, and the second outer block bar 412, the second intermediate block 432, and the second inner block bar 422 are sequentially tightened and fixed at the hinges 320.

Since the block bar formed as described above is formed of a steel frame manufactured by roll forming, the straightness is excellent, and the accuracy of manufacturing a desired cross-sectional shape is improved, so that heat insulation and airtightness can be improved. When the steel frame is manufactured by simply welding rather than roll forming in manufacturing the block bar, since the straightness is poor and the space between the block bar itself and the block bars is formed during the joining, the heat insulating efficiency is low and the airtightness There is a problem in that leakage occurs.

The block bar may have a bent shape in each of the fixing portion 310 and the hinged portion 320. By taking such a bent shape, a configuration in which the block bar is in contact with the outside and inside can be achieved .

That is, each of the first outer block bar 411 and the second outer block bar 412 has a configuration in which the first outer block bar 411 and the second outer block bar 412 are opposed to each other in a cuboid shape and a two- So that they can be arranged in such a manner that they are in contact with each other outwardly and inwardly upon contact with each other.

In addition, the first inner block bar 421 and the second inner block bar 422 are each in a lattice-shaped arrangement, and the inner side of the second inner block bar 422 is disposed further inside, When they are in contact with each other, a layout structure in which they are in contact with the outside and inside can be achieved.

In addition, although the first intermediate block bar 432 and the second intermediate block 432 are not shown in the drawings, the first intermediate block bar 432 and the second intermediate block 432 may have a structure in which the first intermediate block bar 432 and the second intermediate block 432 are in contact with each other, The intermediate gasket 433 connected to each of the first intermediate block bar 432 and the second intermediate block 432 may be in contact with the inner and outer sides when they are in contact with each other.

As described above, when the block bars are in a bent shape and are in contact with each other at the outer side and the inner side when they are in contact with each other, the vertically or obliquely struck air from the outside easily enters through the outer window 300 It is possible to increase the heat insulating ability by effectively blocking the heat exchange.

In addition, the intermediate insulating layer 430 may be filled with a heat insulating member 429. Specifically, the openings of the first intermediate block bar 432 and the second intermediate block 432 may be filled with the heat insulating member 429 may be filled. It is needless to say that such a heat insulating member 429 may be made of any material as long as it is made of a material having a low thermal conductivity.

A gasket may be attached to each of the outer heat insulating layer 410, the inner heat insulating layer 420 and the intermediate heat insulating layer 430 along the contact point between the fixing portion 310 and the hinged portion 320.

An outer gasket 413 is attached to the first outer block bar 411 and a second inner block bar 422 is attached to the inner heat insulating layer 420. The second inner block bar 422 is attached to the inner heat insulating layer 420, The intermediate gasket 433 may be mounted on the first inner block bar 421 and the second inner block bar 422. The intermediate gasket 433 may be mounted on the first and second inner block bars 421 and 422. [

The inner heat insulating layer 410 and the inner heat insulating layer 420 may be formed of a roll-forming steel frame at the fixing portion 310 and the hinged portion 320, respectively. Gasket grooves 411a and 422a may be formed. That is, the gasket grooves 411a and 422a may be formed when the first outer block bar 411 and the second inner block bar 422 are roll-formed.

As described above, the gasket is attached to the outer heat insulating layer 410, the inner heat insulating layer 420, and the intermediate heat insulating layer 430 along the contact points of the fixing portion 310 and the hinging portion 320, So that the heat insulating ability can be increased as well as the intrusion of outdoor rainwater can be completely blocked.

A supporting member may be installed on each of the outer heat insulating layer 410 and the inner heat insulating layer 420 so that the glass 322 is inserted and fixed in order to mount the glass 322 inside the hinges 320. At this time, as an example of the support member, an outer support member mounted on the second outer block bar 412 and an inner support member mounted on the second inner block bar 422 may be formed as shown in the figure. The inner support member may include an inner friction member 425 which is in contact with the glass 322 together with the inner support block bar 424. The outer friction member 414 may have a frictional surface, ).

Here, the outer window 300 of the present invention is described as being made of a steel frame so as to increase the structural performance as described above. Since the steel frame has excellent structural performance and is also resistant to heat, According to the height, it is possible to prevent the glass 322 from falling off due to damage due to high wind pressure and fire.

Meanwhile, the window frame 100 is made of a steel material, and can be fastened by the inner window 200 and the fastening member 500. At this time, the fastening member 500 is fixed to the inner window 200 and is pressed and supported by the window frame 100, so that the window frame 100 is not completely fixed.

In the window frame 100, the thermal expansion slot 100a may be formed such that the inner window 200 made of the PVC frame is movable in the left and right thermal expansion and contraction. That is, since the window frame 100 is made of a steel material and the inner window 200 is made of a PVC frame, even when the window frame 100 is clamped due to a difference in thermal expansion coefficient from each other, . At this time, the fastening member 500 mounted and fixed to the inner window 200 along the thermal expansion slot 100a formed in the window frame 100 is moved to deform and damage the window frame 100 and the inner window 200 .

The fastening member 500 may include a bolt 501 and a nut 502 and a washer 503 for smooth movement of the nut 502 with respect to the window frame 100.

The moisture absorbing material 630 and the reinforcing gasket 640 may be filled with the sealant 610 and the silicon 620 between the PVC frame of the inner window 200 and the steel frame of the outer window 300. When the viscous liquid is applied on the silicon 620 and the material of the sealant 610 is damaged by the thermal expansion of the inner window 200 and the outer window 300, Since rainwater or dew condensation water permeates between the PVC frame and the steel frame of the outer window 300, in order to prevent this, the spacing space is filled by the reinforcing gasket 640 and the moisture absorbing material 630 absorbs moisture , It is possible to prevent the inner window 200 and the outer window 300 from being damaged by moisture. The moisture absorbent 630 may be formed of a plastic case 631 having a plurality of holes through which moisture can pass and a silica gel 632 filled in the case 631.

According to the present invention configured as described above, since the outer window 300 is made of a steel frame having excellent structural performance, it can withstand high wind pressure and fire, and can have stable and robust durability.

The heat insulating structure 400 of the external window 300 has a structure in which the external heat insulating layer 410, the inside insulating layer 420 and the intermediate insulating layer 430 are provided so as to be three-dimensionally insulated, By taking airtight structure, it is possible to increase heat insulating capability and effectively block the intrusion of outdoor rainwater by effectively blocking heat exchange.

In addition, since the insulating structure 400 of the outer window 300 is formed of a block formed of a steel frame manufactured by roll forming, since the straightness is excellent and the precision of manufacturing a desired cross-sectional shape is improved, .

The thermal expansion slot 100a is formed in the window frame 100 to connect the window frame 100 and the fixing member 500 fixed to the inner window 200, So that deformation and damage of the window 200 can be prevented.

The reinforcing gasket 640 is filled with the sealant 610 and the silicone 620 between the PVC frame of the inner window 200 and the steel frame of the outer window 300 so that the reinforcing gasket 640 is reinforced As the space 670 is filled with the gasket 640 and the moisture absorbent 630 such as silica gel absorbs moisture, it is possible to prevent the inner window 200 and the outer window 300 from being damaged by moisture.
