FIG. 1 is a perspective view of a lightweight type heat insulating curtain wall assembly according to the present invention, FIG. 2 is an exploded perspective view of FIG. 1, FIG. 3 is a sectional view taken along line A-A ' -B 'line, and Fig. 5 is a perspective view showing the first gasket of another embodiment.

As shown in FIGS. 1 to 4, the first and second supporting frames and the heat insulating frame supporting the glass are alternately combined with each other along the longitudinal direction of the main frame, , The conduction rate of the cold or hot air is reduced to 1/2 to 1/4, and the space between the two spaces is minimized through the second gasket to minimize the flow rate of cold air or heat. To an insulating curtain wall assembly (100).

This lightweight insulating curtain wall assembly 100 includes a main frame 10, first and second support frames 20 and 40, a first heat insulating frame 30, a first gasket 80a, A gasket 80b, and an in-cap frame 50 and an out-cap frame 60. [

The first and second support frames 20 and 40 support the glass 90 so that the first support frame 20 and the second support frame 40 are spaced apart from the first support frame 20 And are fitted to each other via the heat insulating frame (30).

The first adiabatic frame 30 is made of reinforced plastic so as to minimize the conductivity of cold or hot air and maintain rigidity. The first adiabatic frame 30 is manufactured in various lengths depending on the thickness of the glass 90 and is selectively applied thereto.

For example, in the case of the double glass 90, the first adiabatic frame 30 having a short length is selected as shown in FIG. 3A, and in the case of the triple glass 90, , The relatively long first heat insulating frame 30 can be selected and applied.

A coupling surface (11) recessed in the longitudinal direction is formed on the front surface of the main frame (10).

The first support frame 20 coupled with the second support frame 40 and the first heat insulation frame 30 is coupled to the coupling surface 11.

The first gasket 80a may be made of EPDM (ethylene propylene diene monomer), or may be a heat insulating material such as polyurethane foam.

The first gasket 80a is fitted to both sides of the joint portion of the first heat insulating frame 30 and the second support frame 40. [

The first gasket 80a reinforces the bonding force between the first adiabatic frame 30 and the second support frame 40 and the first gasket 80a supports both sides of the first adiabatic frame 30 and the second support frame 40 Quot; gap "G with the glass 90 disposed in the lower portion of the chamber.

In addition, the in-cover frame 50 is coupled to the second support frame 40 and presses the respective glass plates 90 in the direction of the main frame 10.

Of course, the conductivity can be further reduced, but can be selected according to the weight of the glass 90. [

A second gasket 80b having both end faces closely contacted with the respective first gaskets 80a is provided in the longitudinal direction of the main frame 10 in the space SP so that the air- Can be minimized.

Preferably, the second gasket 80b is made of polyurethane foam. In addition, EPDM and a heat insulating material can be used. In addition, a plurality of convection spaces 81 are formed in the inside of the second gasket 80b, Can be canceled.

That is, the first gasket 80a and the second gasket 80b are installed in the "gap G" and the space SP so that the flow rate of the heat or cold air due to the convection phenomenon can be controlled through the convection space portion 81 And a structure capable of maximizing the adiabatic effect can be provided by canceling it with multi-stages.

A plurality of ciliary protrusions 82 are formed on the outer surfaces of the first gasket 80a and the second gasket 80b. The ciliary protrusions 82 formed on the first gasket 80a are in contact with the glass 90, Thereby preventing cold air or heat from being convected to the close contact surface.

5, the first gasket 80a is formed as a single piece in another embodiment, and a groove 83 is formed as a central region, so that the first heat-insulating frame 30 and the second support frame 40, As shown in Fig.

In such a configuration, the first gasket 80a is inserted through the groove 83, and the second gasket 80b is more easily engaged, thereby reducing the construction time.

The out cap frame 60 is engaged with the upper surface of the in-cover frame 50 to finish the surface of the in-cap frame 50 so that the exposed bolt head is not exposed.

Further, a sealing material S is applied between the in-cover frame 50 and the glass 90 and between the main frame and the glass 90, and is subjected to surface finishing together with watertightness.
