Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a window frame renovation method, and relates to an improvement in the so-called pull-out construction method.

As a method for renovating window frames, there is a new cover method in which the bay window frame is left in the building frame and a new window frame is fitted into the bay window frame to attach both window frames, and a new cover method is used to install the bay window frame by pulling it out from the building frame. There is a so-called pull-out construction method in which a new window frame is fitted into the window opening and the new window frame is attached to the building frame. The area can be about the same as that of the old window.

By the way, as a so-called pull-out construction method, for example, Japanese Patent Application Laid-Open No. 57-9979 has proposed, but in this conventional example, the existing window opening remains in the same shape, so a new window frame is installed in the window opening. There was little work space to fit it in and secure it in place, and it was quite difficult.

In order to increase the work space, the shape of the new window frame had to be made smaller, which led to a narrowing of the window opening area, and the advantages of the so-called pull-out construction method could not be fully demonstrated.

Furthermore, in order to improve the above points, the wall surrounding the existing window opening, including the bay window frame, was cut to form a new window opening, and a new window was installed in the new window opening. For example, Japanese Patent Application Laid-Open No. 57-54678 proposes a construction method in which a frame is fitted and fixed.

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, and when the wall thickness is large, the work is quite heavy and laborious. It was fraught with difficulties.

Therefore, the present invention was devised in order to solve all the problems of the conventional method, and it is easy to fit a new window frame, and moreover, the new window frame can be fitted into the building frame. Therefore, in the present invention, the bay window frame can be pulled out and removed without hulling the wall to which the bay window frame is attached, and then installed in the existing window opening. At least the wall on the indoor side on the upper side of the section is cut obliquely from the inner circumferential surface toward the outdoor direction to form a guide part for fitting the new window frame, and then the framed new window frame is inserted into the guide part. The new window frame is fitted into the window opening through the guide portion, and then the outer peripheral side of the new window frame is connected to the building frame from the indoor side via the guide portion, and the new window frame is attached to the building body.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 schematically shows the entire structure of a renovated window frame 11), and the renovated window frame H1l consists of an upper frame main body (2), a pair of left side Side frame body (3)
and the lower frame body (4) are framed in a rectangular shape.In the following explanation, each frame body is collectively referred to as the new window frame (5), and the old frame bodies are collectively referred to as the bay window frame ( 6).

Referring to Figure 2, a heavy-duty, wooden, or aluminum material is attached to the building frame (7), and in this example, the mounting groove (8) is attached to the structure (7).
) and is attached using anchor bolts (9), etc., is removed from the wall (10) of the frame (7) using a pulling tool such as a jack or cylinder. )
It is removed by pulling it out without any damage, for example, by the means exemplified in JP-A No. 57-9979, or by other means.

When the bay window frame (6) is pulled out and removed, an existing window opening (11) with a mounting groove (8) is formed as shown in FIG.

Therefore, in the present invention, the surrounding area of the window opening (11), in this embodiment, the indoor side surrounding area on the upper frame side, the indoor side surrounding area on the upper frame side, and the indoor side surrounding area on the side frame side are made of concrete (not shown). Using a cutting machine to insert the new window frame (6) into the guide section +12
form 1.

That is, the wall (10) on the indoor side peripheral part of the window opening (Ill at least on the upper frame side) is cut diagonally from the inner circumferential surface θ to the outdoor direction using a concrete cutting machine to cut the guide part θ as shown in FIG. Form as shown.

Next, the aluminum, pre-framed into a rectangular shape,
In this example, the mounting tongues θ are welded to the outer peripheral wall θ of the new window frame (5) made of hard resin, etc. , fit the new window frame (5) into the window opening (11) via the guide part θ as shown by arrow A in FIG.
Connect the mounting tongue (I5) of the anchor hardware t17) and the Azocar bolt (9) from the indoor side (C) through the connecting bar (l).
I19 6 + 19), the outer peripheral side of the new window frame (6) and the building frame (7) are connected in short and the new window frame (6) is connected.
) is attached to the building frame (7) in a state where it is partially fitted into the attachment i81 in this embodiment.

The above-mentioned first persimmon example is carried out on the upper frame side or the upper Azusa side and the side frame side, but the embodiment shown in FIG. 6 is adopted on the lower frame side.

A plurality of metal base fittings (21) each having a length extending over the entire length of the frame or a length extending over a predetermined interval in the direction of the frame length are installed on the drainage slope part (sha) of the frame (7) from which the old lower frame main body has been pulled out and removed. Fix it with Anchor bolts (Co., Ltd.), fix the lower frame main body support fitting (2) to the base metal fitting @υ via the connecting bar (241), and fix the new window frame ( 6) The lower frame body is supported from below.

Note that a plurality of lower frame main body support fittings (to) are provided at predetermined intervals in the direction of the frame length.

In addition, in the first embodiment of the mounting structure shown in Figs. 4 and 6, the lower part is the inner side frame, and the length L is the entire length of the frame.
Support metal fittings (7 in 2 barrels) are made of extruded material and are fixed to the side end surface of the indoor side (C) of the new window frame (5) via fasteners (B).
It is attached via Asuna (c).

Also, - indicates the material to be deleted, and the signature frame body and its supporting metal fittings (
2) are collinear with the fastener (3I) to provide the entire length of the lower frame on the outdoor side (B).

The bolt is attached to the frame on the lower indoor side, and is removably placed on the support hardware attached via the fastener (side) via the engaging part.
