DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a curtain wall which can be used on both the wife side and the girder side of a building and a window mounting apparatus.

[0002]

2. Description of the Related Art Curtain wall windows are generally installed at different positions when the windows are provided on the wife side and the girder side of a building. A glass is attached to the opening, and the exterior of the building is covered with glass. As an attachment means of the glass, a backer is formed on both sides of the back surface of the glass, an exterior unit in which the vertical bone is adhered via a structural seal, and the vertical bone of the unit is completely fitted into a fitting groove provided on the side surface of the cubic. In addition, there is a known one that prevents an exterior unit from coming off a cubicle and supports the glass without eyes. (For example, Japanese Utility Model Laid-Open No. 1-315538, Japanese Utility Model Laid-Open No. 3-8081)
No. 2)

Vertical frame members are attached to the inner peripheral portions of the left and right cubicles, respectively.
Glass is inserted between the open ports provided on the outdoor side of both vertical frame members,
There are also known those in which glass is fixed using packing and caulking, and those in which a sash window or a sash frame is inserted from above into a fitting groove on the left and right sides and the glass is fitted into the sash frame. (For example, JP-A-63-102913 and JP-A-63-53418)

[0004]

When the window frame is mounted on the side of the wife and the side of the girder, there is a problem that different auxiliary tools must be used for mounting the window frame. For the curtain wall to be installed,
There is a problem that the fitting must be performed while being careful not to break the glass, and there is also a problem that it is dangerous and inconvenient to fit the heavy exterior unit in a high place where the scaffold is poor.

[0005] As means for attaching the curtain wall, the upper frame material and the lower frame material are fixed to the horizontal member of the skeleton, and the vertical frame material is fixed to the vertical member. However, there was also a problem that the rain closing at the window connecting portion was incomplete. Particularly in a high-rise building, the floor height is, for example, 1,
3420cm on the 2nd floor, 3000cm on the 3rd to 6th floor, 7,8
There is a problem that the structure of the window and its installation are difficult because the floor is different, such as 3300 cm. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object the purpose of being able to easily attach to both the wife side and the girder side, shortening the construction period, An object of the present invention is to provide a curtain wall construction method and a window mounting device that can improve the appearance design later.
