DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for renovating a new window frame using an existing window frame provided at an opening of a building.

[0002]

2. Description of the Related Art Prior art techniques for attaching a new window frame to an existing window frame are disclosed in, for example, JP-A-49-110127, JP-A-57-184179, and JP-A-58-83587. In these prior arts, after the base material is attached to the lower frame of the existing window frame, the lower frame of the new window frame is fixed to the base material, and a space is provided between the lower frame of the existing window frame and the base material. It is formed. Due to this space, the lower frame of the new window frame has a problem that its central portion is bent downward by the action of its own weight or an external force, and cannot be mounted horizontally and linearly. If the lower frame of the existing window frame is already bent,
Since the base material is attached to the bent lower frame, there is a problem that the new lower frame cannot be horizontally attached to the existing lower frame with high accuracy.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to enable the lower frame of a new window frame to be mounted horizontally with high precision, and to improve the mounting accuracy of the new window frame on an existing window frame. The purpose of the present invention is to provide a window renovation method.

[0004]

According to the present invention, a first support member is mounted on a lower frame of an existing window frame, and an L-shaped first member is provided on a vertical frame of the existing window frame so as to protrude inside the existing window frame. (2) The support member is fixed such that its support surface is flush with the support surface of the first support member, and the lower frame of the newly-installed window frame is mounted on each of the support surfaces of the first and second support members. The new window frame is fitted into the existing window frame, and between the lower frame of the new window frame and the lower frame of the existing window frame, a hard filler is provided with a gap from the inner surface of the vertical frame of the existing window frame. This is a window reforming method characterized by injecting and curing.

[0005]

According to the present invention, the first support member is placed on the lower frame of the existing window frame, and the second support member is fixed to the vertical frame of the existing window frame. At this time, the fixed position is set such that the support surface of the second support member is flush with the support surface of the first support member,
Therefore, even when the lower frame of the existing window frame is already bent, the height of the support surface of the second support member is made to match the height of the support surface of the first support member placed on the lower frame. The lower frame of the new window frame is mounted on each of the support surfaces of the first and second support members, and the new window frame is fitted into the existing window frame. In this manner, regardless of the shape of the lower frame of the existing window frame, with the lower frame of the new window frame arranged horizontally, the hard filler material is inserted between the lower frame of the new window frame and the lower frame of the existing window frame. , And is hardened, thereby reliably preventing the lower frame of the new window frame from being bent between the first and second support members, thereby improving the mounting accuracy. Further, since the filler is provided with a gap from the inner surface of the vertical frame of the existing window frame, water flowing down the vertical frame of the existing window frame can be satisfactorily discharged, thereby improving drainage.
