In the present invention, the supporting frame support protrusions 181 are formed so that the I-shaped reinforcing bars can be installed on the supporting frame 180.

In order to prevent the aluminum support frame from being deformed, reinforcing steel having a shape of '□' or 'C' has been used. However, it is not easy to engage with the support frame and a large amount of steel is used due to its shape, In the present invention, by using an I-shaped steel panel, it is possible to easily assemble it, and to reduce the load and the cost due to the use of the steel.

Hereinafter, a method of manufacturing the window system of the present invention will be described in detail.

First, the window fixing frame 160 and the window frame 170 are manufactured by injection molding aluminum of the present invention. The frames are formed with an engaging groove and an embankment rest fixing protrusion 150 capable of engaging the window end frame 120 and the window frame end frame 130. At the upper end of the window frame 170, .

The window end frame 120 and the window frame end frame 130 are manufactured by injection molding a polyamide resin containing 15 to 23% of a fiber material such as synthetic resin or glass fiber.

At the inner end of the window frame 120, there is formed a coupling protrusion which can be engaged with the window frame, a groove for inserting the gasket 210 is formed at the lower end of the window, Thereby forming a groove for engaging the gasket with the engaging projection capable of engaging with the frame.

The support frame 180 is manufactured by injection molding aluminum, and the reinforcing bar support protrusion 181 is formed at the corner portion.

Hereinafter, a method for assembling the above-described members will be described in detail.

The engaging projections of the window end frame 120 and the window frame end frame 130 are slidingly engaged with the engaging grooves of the window securing frame 160 and the window frame 170.

The combined window end frame 120 and the window frame end frame 130 are pressed and fixed by a compression roller so as not to be separated from the window fixing frame 160 and the window frame 170.

Then, the gasket is inserted into the gasket insertion grooves of the window end frame 120, the window frame end frame 130 and the window frame frame 170.

The window fixing frame 160 and the window frame 170 are cut to fit the window size and window frame size and the window fixing frame 160 is fixed to the window glass with the fixing silicone 140 A handle 110 is formed on the lower end of the window frame 120 and the window end frame 120 is sealed and fixed to the lower end of the window 101 with a sealing material 220.

The window frame frame 170 is tightly fixed to the upper end of the support frame 180 and the window frame end frame 130 is sealed and fixed to the fixing window 100 by a sealant 220.

As described above, the window system of the present invention integrates each component and cuts and assembles the components, thereby completing and attaching the window frame and the window frame frame in one step. The process is simple and consistent and economical.

An air insulating layer 200 is formed at a portion where the window frame end frame 130 and the support frame 180 are in contact with each other. The air insulating layer 200 together with the window frame end frame 130 serves to improve the heat insulating property.

A stiffener 190 is inserted into the supporting frame 180 and the fixing window 100 is fixed to the supporting frame 180 by the fixing silicone 140.

The manufactured window 101 is fixed to the window frame 170 as shown in Fig.

First, the emblem rests 231 and 232 are installed in accordance with the positions of the emblem fixing projections 150 formed on the window frame 160 and the window frame 170.

The arm bars are coupled to the arm rests 231 and 232 and are fixed to the window fixing frame 160 and the window frame 170.

Hereinafter, the heat shield effect of the window system according to the present invention will be briefly described.

As shown in FIG. 4, when the handle 110 coupled to the window fixing frame 160 is pushed, the window 101 can be opened in the window frame 170 to circulate the inside and outside air.

The window fixing frame 160 and the window frame 170 are closed by the gasket 170. The window fixing frame 160 and the window frame 170 are formed in the same shape as the window frame 110, And the window end frame 120 and the window frame end frame 130 are closely contacted by the gaskets 210 and 210-1.
