Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a window renovation device, and more specifically to a window renovation device used in the so-called pull-out construction method.

(Prior Art) 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 square shape is inserted in advance, and the new window frame is constructed using the old window frame. Although it can be attached to objects and has certain advantages, since it uses the old window frame, the mounting strength is insufficient and the opening area of the new window frame is smaller than the opening area of the old window frame. There is a problem with this.

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.

(Problem to be Solved by the Invention) By the way, since the pull-out method involves removing the old window frame from the building, it does not have the same problems as the cover method. This was quite difficult, required heavy physical labor, and required special mechanical equipment.

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.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a window remodeling device that eliminates the drawbacks of the above-mentioned drawing method while still retaining its advantages.
