In a building supporting horizontal load due to vertical load and wind or earthquake applied to the building by the columns and beams of the building, the wall is simply a curtain, which simply blocks the space. Therefore, These curtain walls function to block rain and wind from the outside and to block noise and heat. Recently, as more buildings using glass are used, and as the exterior material is advanced, the pillars and beams are exposed to the outside The use of curtain walls which are advantageous for fixing glass and the like is rapidly increasing.

The curtain wall generally has a plurality of glass (double-layer glass) installed and fixed between the horizontal frame and the vertical frame in a state where a horizontal frame and a vertical frame made of aluminum material are crossed with each other at regular intervals on the outer wall or opening of the building In this case, since heat is transferred to the outside through the frame of the metal material and energy loss may occur, the frame of the curtain wall, in particular, the horizontal frame exposed to the outdoors and / The insulation performance of the building is increased.

However, since it is not easy to install the heat insulating material on the outside of the frame exposed to the outside as described above, and since the weight of the cover including the heat insulating material is heavy, the cover must be firmly fixed to the frame or the like. There is a disadvantage that it takes time.

In order to solve the problem of installing the above-mentioned heat insulating material on the outside of the frame constituting the curtain wall, a method of installing a heat insulating material inside the frame has been proposed. As one example thereof, Japanese Patent Application No. 1230245 And a heat insulating box of a steel curtain wall system disclosed in the above description.

The curtain wall disclosed in the patent document is welded to a vertical frame as shown in FIG. 1, and a first support 100 (see FIG. 1) having at least one of a heat conduction blocking paint, a refractory paint and a heat conduction blocking film formed therein, A heat shield member 110 inserted into the first support 100 to form a heat shield space and having a plurality of protrusions formed on an outer surface of the folded portion, A second support 120 formed by bending both ends opposite to the first support 100 and an end inserted into the first end 110 of the first support 110 and the second support 120 A heat insulating member 130 formed of a prong member for supporting the heat insulating member 130 and a heat shield member 110 of the first supporting member 100 in which the heat insulating member 130 is inserted and a second support member 120 for integrally connecting the heat shield member 110 and the second supporting member 120, So that the bending portions of the first support 100 and the second support 120 can be inserted at both ends, Is formed of a plurality of polyamides formed by a U-shaped bend, and heat insulation is performed by a heat block member (110) installed inside the vertical frame, thereby preventing loss of heat energy.

However, since the curtain wall having the above-described structure is complicated in structure and the first support 100 is fixed to the vertical frame by welding, it is difficult to assemble and install the curtain wall in the field, There is a problem that a considerable time is required for assembling and installing the heat shield members 100 and 120 and the heat shield member 110 and the heat insulating material 130 together.

In addition, since each of the constituent parts constituting the curtain wall is different from each other, there is a disadvantage in that a large number of types of molds are required to manufacture the component parts, which requires a large manufacturing cost.
