Description

[Detailed Description of the Invention] The present invention relates to a window frame attachment device for a curtain wall using lightweight aerated concrete panels.

To attach a window frame to a curtain wall using lightweight aerated concrete panels (hereinafter referred to as ALC boards), an opening is formed by the left and right ALC boards and the top and bottom ALC boards (hanging walls, waist walls). Although it is installed in that opening, the window frame cannot be attached directly to the ALC board.

Therefore, conventionally, the opening is reinforced with a reinforcing material such as reinforcing steel or light mountain shape steel, a mounting material is welded and fixed to this reinforcing material, and a window frame is attached to this mounting material.

For this purpose, it is necessary to install reinforcing materials, weld and fix the mounting materials, and attach the window frame to the mounting materials on site. This increases the number of cases, and the construction period becomes longer.

In addition, since the hanging walls and waist walls use ALC boards with the same thickness as the left and right ALC boards, the hanging walls and waist walls must be directly attached to the building frame in the same way as the left and right ALC boards. First, it has problems such as the installation work becoming troublesome.

The present invention was developed in view of the above circumstances, and its purpose is to reduce installation work on site and allow window frames to be installed in openings, shorten the construction period, and improve the construction of hanging walls, waist walls, etc. To provide a window frame mounting device for a curtain wall using lightweight aerated concrete panels, which allows the upper and lower walls to be easily mounted.

As a result, the installation work of the waist wall E becomes easy, and a gap can be formed between the waist wall E and the upper mounting material 10, and in this gap, the receiving piece 34 attached to the upper mounting frame 20 can be mounted upward. Since it can be fixed to the mounting material 10, the upper mounting frame 20 and the receiving piece 34 do not interfere with the waist wall E, making it easy to mount and fix them.

In addition, in the above embodiment, the case was described in which the opening was formed by the left and right ALC boards and the waist wall, but when the opening was formed by the left and right ALC boards, the upper and lower hanging walls, and the waist wall, The waist wall may be attached in the same manner as the above-mentioned hanging wall, and the lower frame may be attached in the same manner as the above-mentioned upper frame.

Since the present invention is as described above, on-site installation work is only required by fitting the window frame with the surrounding mounting frame into the opening and fixing the mounting frame to the frame body via the mounting member. Since the window frame can be installed in a short time, the construction period can be shortened and the advantages of the curtain wall using lightweight aerated concrete panels are not lost.

In addition, the upper and lower walls are thinner than the left and right lightweight aerated concrete panels, and gaps are formed between the upper and lower walls and the frame body. Since it is attached to the window frame, it is easy to install the upper and lower walls, and the mounting member that secures the mounting frame attached to the window frame to the frame body can be easily attached to the upper and lower walls.
Since it can be fixed to the frame body in the gap between the upper and lower walls and the frame body, the installation work can be easily performed.
