The present invention relates to a fastening structure for a building window frame, and more particularly, to be easily assembled and installed at a construction site, so that even a large window frame can be easily transported and can prevent deformation or damage during transport. It relates to a fastening structure for building window frames.

In general, the building window frame is divided into a window frame that can be opened and closed as the rail is installed on the lower left and right running on the window frame frame, and the window frame inserted and fixed in the window frame frame, the present invention is the latter Since the present invention relates to a fixed window frame, only the fixed window frame (hereinafter, referred to as "window frame") will be described.

Conventional window frame is shown in Figure 1, briefly described with reference to the following.

1 is a perspective view showing a conventional building window frame.

As shown in the drawing, a conventional building window frame is composed of two upper and lower horizontal frames (horizontal frame) 1a, 1b and two vertical frames (vertical frame) 3a, 3b for supporting glass. The horizontal frame and the vertical frame are fastened to each other by a fastening member (not shown) to form a rectangular frame. In this case, the horizontal frame and the vertical frame forming the window frame are made of various materials such as steel or steel or aluminum.

When the window frame is completed in the form of a square frame as described above, to carry the completed window frame to the construction site, in the case of the normal transport of the window frame at least one or more carriers to carry the completed window frame .

At this time, when the carrier grasps the horizontal frame 1a, 1b or the vertical frame 3a, 3b of either side, the fastening member holding the horizontal frame and the vertical frame is loose without maintaining the tightening state securely. There was a problem that could be lost.

In addition, the above problems are more frequently generated due to the increased weight of the horizontal frame and the vertical frame due to the enlargement of the window frame.

Therefore, a problem arises in that productivity is reduced due to reassembly as the coupling force of the horizontal frame and the vertical frame assembled during transportation is reduced, and the window frame assembled when the fastening member loosened due to the load of the window frame is released. There was a problem of falling to this floor, and there was also a problem of economic loss, such as the need to replace the window frame due to forced release of the fastening member.

In addition, there is a problem in that the cost burden, such as requiring a large transport means when transporting a large window frame.
