Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for installing a window frame in a curtain wall using lightweight aerated concrete panels.

In order to attach a window frame to a curtain wall using lightweight aerated concrete panels (hereinafter referred to as ALC boards), an opening is formed using the ALC board and the window frame is attached to that opening, but due to the strength For some reason, it is not possible to attach the window frame 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.

The present invention was made in view of the above circumstances, and its purpose is to use lightweight aerated concrete panels that can reduce installation work on site, allow window frames to be attached to openings, and shorten the construction period. The purpose of the present invention is to provide a method for installing a window frame of a curtain wall.
