For example, as in the embodiment shown in FIG. 1, two window boxes 30 may be provided as a pair, or three or more windows may be provided. Hereinafter, the case where they are provided as a pair will be described as an example, but the window panel 30 is not limited to this and may be provided as a plurality of three or more depending on the building.

The window airtight device 10 of the present invention is formed by being coupled to the window 30, and can block the outside air and improve wind pressure resistance by airtightening the gap between the window frame 20 and the window 30. The window airtight device 10 according to the present invention is to be coupled to the windbreak frame 33 installed in the vertical direction at the portion (hereinafter referred to as the fastener) where the plurality of window panels 30 overlap each other when the window panel 30 is closed. You can. Specifically, the windbreak frame 33 is installed in the vertical direction of the window along the vertical frame 32 of the window 30, which is disposed in the fastening section where a pair of window 30 overlaps each other when the window 30 is closed. It can be provided in any direction. The unexplained symbol 31 is the horizontal frame of the window 30. At this time, the window airtight device 10 according to the present invention is coupled to the window at the part where the window 30 meets the window 30, so that the gap between the window frame 20 and the window 30 can be sealed to seal the gap. .

Hereinafter, the window airtight device 10 according to the present invention will be described in detail with reference to FIGS. 1 to 5. 1 to 5, the window airtight device 10 according to the present invention includes a case member 100, an airtight pad 200, and a reinforcement plate 300.

That is, the case member 100 may be coupled to the side of the windbreak frame 33 and may be provided to airtighten the portion of the window frame 20 where the rail 21 is formed. One side of the case member 100, that is, the side facing the window 30, may be concave to form an assembly space. An airtight pad 200 and a reinforcement plate 300 may be placed in this assembly space.

The airtight pad 200 is placed in the assembly space, assembled to the case member 100, and is provided to airtightly seal the space between the window frame 20 and the window panel 30.

Specifically, the airtight pad 200 may be formed in a plate shape and fitted into the surface of the case member 100 facing the window 30. The airtight pad 200 is intended to completely adhere between the window 30 and the rail 21 of the window frame 20. Through this, the gap between the rail 21 and the window 30 is minimized to allow the air to flow from the outdoor side to the indoor side. It can block the flow of air from indoors to outdoors.

There is no limitation on the material of the airtight pad 200. For example, the airtight pad 200 may be made of a thin, soft synthetic resin material, sponge pad, or elastic rubber material to increase the adhesion of the gaps between each member. You can. As a result, the airtight pad 200 is made of a flexible material, which not only makes it easy to insert the window panel 30 into the window frame 20, but also improves adhesion by minimizing the space formed between the window panel 30 and the window frame 20. By improving the airtightness and insulation of windows, it is possible to improve them. Additionally, the sliding operation of the reinforcement plate 300 can be performed smoothly. However, the material of the airtight pad 200 is not limited to this, and various materials can be applied as long as they can provide airtightness between members.

The reinforcement plate 300 is placed in contact with the airtight pad 200 in the assembly space, is assembled to the case member 100, and is assembled to be able to slide in the vertical direction.

It may be installed in either one (see FIGS. 8 to 12), or it may be installed on both the upper and lower ends of the windbreak frame 33 (see FIG. 13).

With the window airtight device 10 installed on the top of the windbreak frame 33, when the reinforcement plate 300 moves upward, the locking dimension of the airtight device with respect to the rail 21 of the window frame 20 increases. You can do it. As a result, when a strong wind blows outside, separation of the window 30 from the window frame 20 is minimized, and the wind pressure resistance performance of the window 1 can be improved.

As an example, the window airtight device 10 is installed between the rail 21 of the window frame 20 and the window 30 in an environment where wind (gusts, typhoons) blows frequently and a lot depending on the climate conditions in which the window is installed. It is possible to improve the wind pressure resistance of the window by sliding it in the direction of the window frame 20 so that it adheres more closely to block the wind and outside air flowing in from the outside. On the other hand, in an environment where there is relatively little wind, the reinforcing plate 300 can be slid in the direction of the window 30 to couple the window airtight device 10 of the present invention to the window 30.

In addition, the reinforcement plate 300 is provided to be able to slide in the vertical direction, so that the reinforcement plate 300 is manufactured in a processing factory so that it does not protrude from the top of the case member 100, and then the climatic conditions in which windows are installed at the construction site are met. Accordingly, the construction worker can simplify the window construction work and improve the convenience of construction by simply manipulating the position of the reinforcement plate 300 to move upward/downward so that the window can have appropriate wind pressure resistance.

In this way, the window airtightness device 10 according to an embodiment of the present invention is provided with a sliding reinforcement plate 300 together with the airtight pad 200, thereby improving the airtightness and wind pressure resistance performance of the window 1 at the same time.
