Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a window renovation method, and more specifically to a window renovation method using a so-called pull-out method.

Many cover methods and pull-out methods have been proposed and put into practical use as window renovation methods.

Here, the cover construction method means that the old window frame is left in place without being removed from the building, and a new window frame that has been framed in a rectangular shape is inserted in advance, so that the new window frame utilizes the old window frame. Although it has certain advantages, since it uses the old window frame, the installation strength is insufficient and the opening area of the new window frame is larger than the opening area of the old window frame. There is also a problem that the size of the image becomes smaller.

In order to solve this problem, the so-called pull-out method, in which the old window frame is pulled out from the building and then the new window frame is fitted and attached to the building, is proposed, for example, as disclosed in Japanese Patent Laid-Open No. 57-1999.
9980, etc.

By the way, this pull-out method involves removing the old window frame from the building, so although it does not have the disadvantages of the cover method described above, it is quite difficult to remove the old window frame from the building and requires heavy manual labor. So,
Also, special mechanical equipment was required.

In addition, especially with this method, the old window frames are pulled out unevenly, and the walls of the building, such as mortar and tiles, fall off during pulling out, which can be dangerous when working on floors. As a result,
Moreover, post-processing was troublesome.

Therefore, the present invention has been devised to eliminate the disadvantages of the above-mentioned drawing method while retaining the advantages of the drawing method. Therefore, in the present invention, the upper frame body of the old window frame After forming a separation groove of a desired depth in the longitudinal direction of the frame along the vertical wall of the frame on three sides of the periphery of either the outdoor side or the indoor side or both of the building in which the frame is buried, The method is characterized in that the old window frame is pulled out from the building through the separation groove, and then the new window frame is attached to the building.

Embodiments of the present invention will be described in detail below with reference to the drawings.
