Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a window renovation method in which an old window frame is renovated and a new window frame is attached thereto. The idea is to leave it in place without removing it from the base, and attach it to it so as to cover the main body of the new window frame, thereby improving its appearance.

There have been many cases in the past where an old frame body is used as it is as a mounting base for a new frame body, but the old frame body usually becomes obsolete due to rust etc. due to long-term use, and if it is used as it is, it will not be possible to install a new frame body. It cannot be used as a mounting base for the main body. To solve this problem, a reinforcing plate is welded to the old frame body, or a reinforcing plate is fixed to the old frame body using anchor bolts such as hole-in anchors or dry pits, and a new frame body is attached to the reinforcing plate. A technique has been proposed that does this. However, simply welding the reinforcing plate to the old frame body in this way poses a risk of the reinforcing plate peeling off from the building base together with the old frame body as the old frame body itself has deteriorated. It is unstable. Furthermore, if the reinforcing plate is fixed to the building base using anchor bolts, the work of installing the anchor bolts is troublesome and does not improve efficiency, and there is also the problem that the building base itself may be damaged during the installation.

The present invention focuses on the above-mentioned drawbacks, and makes it possible to provide a mounting base with sufficient strength in contact with the old frame main body without directly placing any burden on the old frame main body or building base. An embodiment of the present invention will be explained below with reference to the drawings. In Figs. The frames are mainly made of old steel sashes that have survived without any problems.3 and 4 are the upper and lower frames, and 5 and 6 are the frames.
are its left and right vertical frames. Also, 7 is the main body of the frame, such as a new aluminum sash.

The present invention is characterized in that reinforcing members 8 and 9 having the following structure are attached to the old frame body 1 before the new frame body 7 is fitted into the old frame body 1.

As shown in FIGS. 3a and 3b, the reinforcing members 8 and 9 are upper and lower frame reinforcing members 8a and 8b made of curved iron or steel plates, each having a substantially U-shaped cross section, left and right vertical frame reinforcing members 9a, 9b, and each reinforcing member 8, 9 is formed of a long material that is approximately the same length as or slightly shorter than the upper and lower frames 3, 4 and left and right vertical frames 5, 6 of the old frame main body 1. Of these, the upper and lower frame reinforcing members 8 are integrally provided with bendable tabs 10, 10 at both ends in the longitudinal direction, respectively.
0 is bent in advance, preferably at an angle of about 45 degrees, upwards as shown in the figure.

First, as shown in FIG.
Attach it by leaning it against the inner surface of the
Next, the left and right vertical frame reinforcing members 9a, 9
Insert the upper and lower frame reinforcing members 8a and 8b into the space between b in a slightly inclined state as shown by the dashed line in FIG.
Hammer in using an appropriate tool as shown by the arrow.
As a result, the ears 10, 10 integrally formed at both ends of the upper and lower frame reinforcing members 8a, 8b slide while being pressed against the left and right reinforcing members 9a, 9b, and the upper and lower frame reinforcing members 8a, 8b are brought into a horizontal state. In this state, the upper and lower frame reinforcing members 8a and 8b are forcibly bent.
are attached to the old upper and lower frames 3 and 4 as shown by solid lines. In addition, when attaching the upper and lower frame reinforcing members 8a and 8b to the old upper and lower frames 3 and 4, as shown in FIG. Using the pieces 11 and 12, this double sliding door shoji rail strip 11a, 11b or 12
It is preferable that the upper and lower frame reinforcing members 8a, 8b are slightly forcefully fitted between the upper and lower frame reinforcing members 8a, 12b.
Therefore, the left and right vertical frame reinforcing members 9a connected thereto,
9b can be prevented from wobbling in the indoor and outdoor directions.

After that, as shown in FIG.
10 to the left and right vertical frame reinforcing members 9a, 9b by welding 13, the upper and lower frame reinforcing members 8
a, 8b and the left and right vertical frame reinforcing members 9a, 9b are framed along the four circumferences of the old frame main body 1, and are fixed to the old frame main body 1 in a press-contact state without directly imposing any processing burden on the old frame main body 1. It turns out.

In particular, by sliding the ear pieces 10, 10 in pressure contact with the left and right vertical frame reinforcing members 9a, 9b and forcibly bending them, these reinforcing members 9a, 9b
Horizontal surface pressure is applied to the reinforcing member, completely preventing the reinforcing member from wobbling against the old vertical frames 5 and 6, and firmly fixing the reinforcing member to the old vertical frames 5 and 6. In addition, the number of welded parts is reduced and the wobbling is prevented. Welding work is easy because there is no

Furthermore, instead of welding 13 as a means for connecting the reinforcing members 8 and 9, screws 14 such as blind rivets or flat screws may be used as shown in FIG.

After the reinforcing members 8 and 9 are fixed to the old frame main body 1 in this way, the new frame main body 7 is fitted into the framed reinforcing members 8 and 9, and is engaged with the anchor engaging portion 7a. By welding the anchor hardware 15 to the reinforcing members 8 and 9, the new frame main body 7 is fixed to the old frame main body 1.

Reference numerals 16, 17, and 18 are decorative picture frames for covering the old frame main body 1 and the anchor hardware 15 to improve their appearance, and the mounting hardware 19 is welded and screwed to the anchor hardware 15 and the new frame main body 7, respectively. 2
0 with screws 21 and 22 or an engagement stop 23. 24 is a new shoji to be fitted into the frame main body 7.

Therefore, according to the present invention, metal reinforcing members are attached to almost the entire area of the left and right vertical frames and upper and lower frames of the old frame main body, and these metal reinforcing members are fixed to each other. By assembling the members in pressure contact with the old frame main body, and fixing these reinforcing members to the old frame main body, and using the framed reinforcing members as a mounting base, the new frame main body was fitted and fixed. There is no need to perform any installation work on the old frame body by just pressing the reinforcing member evenly on the four circumferential inner surfaces of the frame body, and even if the old frame body has deteriorated, it can be installed directly. Since it is not used as a base, the new frame main body can be firmly attached to the old frame main body.
