Abstract

PURPOSE:To facilitate a work and to prevent entrance of rainwater by a method wherein the wall body of the peripheral part on the indoor side of an window opening part is cut obliquely in an outdoor direction from an inner peripheral surface to form a guide part, and a new window frame is coupled to a building body to form an inner auxiliary frame for screening a guide part. CONSTITUTION:A wall body 10 of at least the peripheral part on the indoor side on the upper frame side of a window opening part 11 formed by a pull-off method is cut obliquely in an outdoor direction from an inner peripheral surface 13 to form a guide part 12. A new window frame 5 is placed through the guide part and coupled to a building body 7. An inner auxiliary frame 26 for screening the guide part 12 containing a coupling tool is mounted. This constitution facilitates a coupling work, and enables ensurance of enough coupling strength with the same natural lighting area as that of an old window frame.

Description

[Detailed description of the invention] (Industrial application field) TECHNICAL FIELD The present invention relates to a renovated window frame renovated using a pull-out construction method.

(Conventional techniques and problems) There are two methods for renovating window frames: the so-called cover method, in which the old window frame is left in the building frame, the new window frame is fitted into the old window frame, and both window frames are attached; There is a so-called pull-out method in which the window frame is pulled out from the building frame, a new window frame is fitted into the existing window opening, and the new window frame is attached to the building frame. Since the old window frame has been pulled out, the window opening area can be made similar to the old window frame.

By the way, as a renovated window frame renovated using the so-called pull-out construction method,
Conventionally, for example, Japanese Patent Application Laid-Open No. 57-9979 has been proposed, but in this conventional example, the existing window opening remains in the same shape, so a new window frame is fitted into the window opening, and the construction is fixed. However, there was little work space and it was quite difficult to do so.

In order to make the work space thicker, the new window frame had to be made smaller, which resulted in a narrower window opening area and the advantages of the so-called pull-out construction method could not be fully utilized.

Furthermore, in order to improve the above points, the wall surrounding the existing window opening, including the old window frame, was cut to form a new window opening, and the new window was installed in the new window opening. For example, a renovated window frame that was renovated using a method of fitting and fixing the frame was published in Japanese Patent Publication No. 57-54.
This is proposed in Publication No. 678.

In this conventional example, the window opening area of the new window frame is very wide, but there are too many cut points in the building frame, which makes the work difficult, especially when the wall thickness is large. It was accompanied by

In addition, since the wall is cut and removed over its entire thickness, even if the cut portion is repaired on the outdoor side,
There was a risk that rainwater etc. would enter from the cut portion.

The present invention provides a renovated window frame that has been renovated using a drawing method that solves these problems.

(Means for Solving the Problems) The present invention provides a new window frame 5 framed in a window opening 11 formed by pulling out and removing an old window frame 6 attached to a wall 10 of a building frame 7. In order to achieve the above-mentioned purpose in the renovated window frame in which the new window frame 5 is fitted to the building frame 7, the following technical measures are taken.

That is, in the present invention, at least on the upper frame side of the window opening 11, the wall body 10 in the indoor side periphery is cut obliquely from the inner circumferential surface 13 toward the outdoor direction, and the fitting guide part 12 of the new window frame 5 is formed. The new window frame 5 fitted through the guide part 12 is connected to the building frame 7 through the guide part 12, and the connecting tools 15, 18, 19, 37, 38, 39
It is characterized by being provided with an inner side frame 26 that hides the guide part 12 including the guide part 12.

(Function) When the new window frame 5 is connected to the frame 7, the connecting parts 15.1B, 1
Since the 9°37, 38, and 39 are connected via the guide portion 12, the connection work is easy and the connection strength is also sufficient.

Since the guide portion 12 including the connecting portions 15.1B, 19.37.38.39 is hidden by the inner side frame 26, it becomes a renovated window frame equivalent to a new window frame even though it is a refurbishment.
