It is made in a structure that can be done.

In general, aluminum is widely used for the frame, which is the frame of the curtain wall. This is because aluminum is lightweight and easy to process. However, the frame made of aluminum has a problem that the frame size must be increased because not only the insulation and fire resistance performance is lower than that of the steel frame, and the rigidity is about 1/3 of that of steel. Therefore, in the case of high-rise buildings, the use of steel frames is increasing in order to improve stiffness and fire resistance due to the increase in the size of the glass surface.

Recently, the energy consumption efficiency class has been decided on the curtain wall, and the improvement of the insulation properties of the curtain wall to increase the energy efficiency class has emerged as an important problem.

In the case of a frame made of aluminum, it is easy to form a coupling structure such as the coupling protrusion 21 due to high workability on the frame surface. However, in the case of high-rise buildings that require high strength of the frame due to the increase in the area of the glass, an aluminum frame is not suitable.

On the other hand, in the case of a frame made of steel having excellent strength, there is a problem that it is very difficult to form a screw hole or a coupling structure for coupling the heat insulating member to the frame surface compared to the frame made of aluminum.

In order to solve the above-described problem, an object of the present invention is to provide a frame structure of a curtain wall that is easy to manufacture while maintaining the rigidity of a steel material.

In order to achieve the above object, the frame structure for a curtain wall of the present invention includes an inner frame made of steel; An outer frame made of aluminum which is coupled to surround second to fourth outer surfaces of the first to fourth outer surfaces of the inner frame except for the first outer surface located in a direction outside the building; And an insulating cover which is coupled to surround the outer surface of the outer frame and insulates the outer frame, wherein a plurality of welding holes penetrating through the outer frame is formed in the outer frame, and the outer frame is in the inner frame In the coupled state, a hollow washer is welded to each of the plurality of welding holes so that the cover frame may be fixed to the inner frame.

In addition, in an embodiment, the washer, a washer body inserted into the welding hole;

A washer head formed on the washer body and having a diameter greater than that of the welding hole; And a hollow penetrating the washer body and a central portion of the washer head, wherein the washer is welded to the inner frame through the hollow, and the outer frame may be fixed to the inner frame by the washer head. .

In addition, in an embodiment, a receiving groove for accommodating the washer head may be provided on an inner surface of the heat insulating cover.

In addition, in an embodiment, a plurality of fitting protrusions protruding are provided on the outer surface of the outer frame, and a plurality of fitting grooves into which the plurality of fitting protrusions are fitted are provided on the inner surface of the heat insulating cover, and the fitting A gasket made of a rubber material may be provided between the protrusion and the fitting groove.

In addition, in an embodiment, the fitting protrusion, the fitting groove, and the gasket may be formed in a bar shape in a direction perpendicular to the length direction of the frame.

According to the present invention, since structures for fixing between the inner frame and the outer frame are provided only on the outer frame made of aluminum with good workability, there is no need to process a separate structure on the inner frame made of steel, which is difficult to process. Because it is easy to manufacture, productivity can be improved.
