Description

[Detailed Description of the Invention] The present invention relates to a window frame structure, and more particularly to a window frame structure that uses an outer frame body and incorporates various types of window frame units inside the outer frame body.

In recent years, aluminum welding technology has been established, and it has become possible to join aluminum shapes to each other by welding, which was previously done with screws. Various structures joined by such welding have significantly increased strength compared to those joined by screws, eliminate the need for fixing members or joint members, and furthermore, because the joints are sealed, This has the advantage that the area is completely watertight and sealing material can be omitted. However, when constructing a window frame by butt-joining aluminum profiles with both ends diagonally cut at an angle of approximately 45° as upper and lower and left and right frame members, the cross-sectional shape of the profiles is required for welding at these ends. must be the same, which poses the problem that welding methods cannot be used depending on the window type. On the other hand, with conventional window frame configurations, it is necessary to change the window format such as sliding windows, fixed windows, outward or inward opening windows, vertical or horizontal sliding bay windows, or bay windows due to renovations, or to replace them with new ones. When replacing the window, large-scale construction work was required to dismantle the mounting and auxiliary members around the building opening and replace the entire window frame.

The present invention was developed after extensive study in view of the above-mentioned situation, and it takes full advantage of the advantages of the welded joint structure, is compatible with various window types, and is capable of replacing them. It is an object of the present invention to provide a window frame structure that is easy to install, fits well in an opening in a building, can be securely installed, and has excellent strength itself.

The window frame unit is assembled and fixed at the position of the hollow frame.

Therefore, in this window frame structure, the advantages of welded joints, which have excellent frame strength and good watertightness around the window frame, can be utilized in various window types, and moreover, the same outer frame body can be Window frame units of different window types can be attached to the window frame unit. For example, when changing the window type due to remodeling or replacing old and new windows, it is possible to easily replace only the window frame unit while leaving the outer frame as it is. In addition, since each frame material of the outer frame has a hollow frame portion, it has a large bending strength, and since the window frame unit is assembled and fixed to the outer frame at the position of the hollow frame, the outer frame The support strength of the window frame unit is excellent. Furthermore, since the outer frame body is fixed to the mounting frame of the opening of the building and the picture frame with screws using the above-mentioned mounting frame portions of each frame material, it fits well and securely in the opening. It has the advantage of being easy to install.
