2. Description of the Related Art To replace a door and a door frame with a new one, it is necessary to remove an existing frame fixed to a building and fix a new door frame in a fixed position. This method
There is no need to use special doorframes for retrofits. However, removing the existing frame from the building is extremely time-consuming. This is because the existing frame is connected to the building frame inside the wall by welding or the like, so that the wall around the existing frame is removed and the existing frame is removed. Also, the removed wall needs to be repaired after fixing the new door frame. Part of the wall is extremely difficult to repair. This is because the repaired part cannot be finished in the same planar state and color as the old part. Therefore, when the door frame is replaced, it is necessary to replace or repaint the entire wall surface, and repairing the wall surface is extremely troublesome.
