Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refurbished window frame installed using a bay window frame.

As is well known, buildings constructed a long time ago were fitted with wooden or iron window frames.

However, these window frames not only have poor soundproofing ability against noise, which has recently come under the spotlight as one of the pollution problems, but also, as a result of long-term use, they deteriorate due to natural phenomena such as rainwater, and eventually deteriorate. However, it has recently come time to renovate with new window frames.

By the way, when renovating to a new window frame, aluminum window frames, which have been commonly used in recent years, are generally adopted as the new window frame.

Therefore, even if the material of the new window frame is iron or the above-mentioned aluminum, the renovation method is to remove the concrete at the window frame opening of the building by so-called chiseling, and remove the bay window frame. The conventional method is to expose the reinforcing bars and install new window frames using these reinforcing bars.

However, with the above-mentioned conventional construction method, the work is not only a major loss, but also the construction costs are large, such as the need to set up work scaffolding outside the cam, and noise and dust are generated during the work. There are many disadvantages such as restrictions on the use of buildings during construction.

For this reason, a technique has been proposed that uses the bay window frame to install a new window frame, but this technology involves fitting the new window frame into the bay window frame and attaching both. Because of the narrow spacing between the frames, the work was quite troublesome, and there were times when it was not possible to achieve a strong and accurate installation.

The present invention has been devised in view of the above-mentioned circumstances, and has excellent wind resistance and strength resistance by increasing the rigidity of the band-like tongue piece having a rain protection function on both the upper frame and side frame of a renovated window frame. The purpose of the present invention is to provide a refurbished window frame with good shape retention.

Embodiments of the present invention will be described in detail below with reference to the drawings.

In each figure, 1.2.3 indicates the upper frame, lower frame, and side frame of the existing Tanfu window frame on the building base 4, and 5, 6
．． 7 shows the upper, lower, and side frames of the new aluminum window frames to be updated, respectively.

In existing window frames made of rice flour, the upper frame 1 and side frame 3 are quite strong, but the lower frame 2 is generally deteriorated due to rainwater, etc.

According to the present invention, the upper frame 5, lower frame 6, side frame 7 of the new window frame
is assembled into a rectangular frame in advance according to the standard according to the window, and this framed thing is used as a new window frame.
Usually adopted.

This new window frame, which has already been framed, is fitted into the remaining double window frame without being removed from the building base 4, and is firmly attached to the building base 4 using this double window frame. .

The specific configuration will be explained in detail in order. First, the lower frame portion illustrated in FIG. 3 will be explained.

A steel plate with a rising part 8a on the front edge, a rising part 8b higher than the above-mentioned rising part 8b on the rear edge, and a lip 8c on the upper end of the rising part 8b. It is mounted on the lower frame 2, and this installation is done using a through-piece (
The term "through material" refers to something whose length spans the entire length of the frame, and the "short piece material" refers to short material that does not span the entire length of the frame, and will be referred to in the same manner in the following explanations.

), and is fixed to the building base 4 with a type of foundation bolt 9 that can be driven from the outside, usually called a dry pit or hole-in anchor, or the old lower frame 2 is fixed to the building base 4. If it is still solid, it is welded to the lower frame 2 by means such as welding, and in short, it is fixed to the building base 4.

For this installation, there is a steel short piece 10 on the stand 8 to set the new lower frame 6 in a predetermined position in cooperation with the rising part 8b, and a rising part to attach the aluminum decorative frame 13 which is a through material. A short piece of steel 11 attached to the lower part of the front wall of part 8a,
A plurality of short pieces 12 are welded in advance at appropriate intervals along the longitudinal direction of the base 8, and a plurality of short pieces 12 are used to attach the picture frame material 14 made of A/L/MINIRAM which is a through material. The lower end of the decorative frame 13 is fixed to the short piece 11 in advance with a rivet 15.

In such attachment, after the stand 8 is fixed on the building base 4 as described above, the short pieces 12 are further welded to the indoor side of the old lower frame 2.

The lower frame 6 of the new window frame is set to this mounting base 8 as shown in the figure, and is connected with rivets 16 and 17 that can be driven only from the outside.
．． 20 is loaded, the picture frame material 14 is fixed on the indoor side with rivets 18, and a rubber gasket 21 is interposed between the lower part of the picture frame material 14 and the base 40, and the renovation of the lower frame part is completed. do.

Next, the upper frame portion will be explained in detail based on FIG. 2.

The new frame 5 is an extruded aluminum material, and a retaining part 5A including a longitudinal groove is formed on the outer periphery of the back of the indoor side edge, and a tongue piece 22 is formed on the outer periphery of the back of the outdoor side edge. In the example, it is integrally extruded.

The band-like tongue piece 22 has the functions of a rain cover and an external picture frame,
From the outdoor edge of the new frame 5 toward the building base 4
The extending end portion corresponds to the outdoor surface of the mouth frame 1, and the extending end portion has a groove-shaped groove that is open in the direction toward the mouth frame 1. It has an airtight material fitting part 22B, and has another retaining part 22A on the outdoor side of the fitting part 22B.

A plurality of metal fittings 23 are installed at predetermined intervals in the longitudinal direction of the frame on the back of the outer periphery of the new frame 5, that is, at a position corresponding to the opening frame 1. The metal fittings 23 are L-shaped bent objects made of steel. As shown in FIG. 5, a rising portion 23a is formed at the end on the indoor side through two strips, and the remaining end 23b on the indoor side is inserted into the groove in the engaging portion 5A of the new frame 5. The rising portion 23a is engaged with the engaging portion 5A from the right side in FIG. 2 toward the indoor side.

Further, the outdoor rising portion 23c of the metal fitting 230 is engaged with the engaging portion 22A of the tongue piece 22.

One piece of the metal fitting 23 is a part that runs parallel to the tongue piece 22, and in this example, it overlaps with the tongue piece, and the other piece has a part that runs parallel to the outer periphery of the upper frame, and in this example, the outer periphery It has an L-shape that overlaps on the surface, and one end thereof is attached to the extending end of the tongue piece 22, and the other end is attached to the indoor side edge of the upper frame, thereby increasing the rigidity of the tongue piece 22. With,
This increases the rigidity of the upper frame.

Note that the metal fitting 23 only needs to have a part along the tongue piece 22 and a part along the outer periphery of the L frame (but not necessarily as shown in the figure).
It does not need to be polymerized.

On the indoor side facing the metal fitting 23 or the tongue piece 22, a steel installation fitting 25 made of a short piece is attached to the above-mentioned mounting base 8.
Similarly, it is fixed to the exposed part of the upper frame 1 by welding or by using foundation bolts 26.

In short, the steel mounting bracket 25 is attached and fixed on the indoor side of the old frame 10.

The mounting fitting 25 has a groove-shaped one side wall 25a that is longer than the opposing wall 25b, and the tip of the one side wall 25a is raised up and a lip 25e is attached. - a mold, the number of which corresponds to the metal fittings 23, and the web corresponding position 25;
d, the bolt insertion hole 31 side is located in the outdoor direction.

The new frame 5 is installed with the elastic airtight material 24 of the tongue piece 22 in contact with the outdoor end surface of the upper mouth frame 1, and in this state, the rising portion 23a of the metal fitting 23 and the web equivalent position 25a of the mounting metal fitting 25 are attached. The reinforcing metal fittings 23 and the mounting metal fittings 25 of the new frame 5 are fastened to each other by using a connecting means (e.g., a tension bolt 27) inserted from the side of the web equivalent position 25a between 1 and 2.
．． Therefore, the new frame 5 is fixed on the top frame 1.

After that, apply the caulking material 28 in the same way as the lower frame part mentioned above.
At the same time, the aluminum frame material 32, which is a pass-through material, is fixed inside the room with the rivets 29 with the backing 30 inserted, and the replacement is completed.

In this case, it is more convenient to make the insertion hole 31 of the bolt 27 of the mounting fitting 25 into a vertically elongated hole shape for vertical alignment.

Next, regarding the side frame portion, this portion has the same basic structure as the above-mentioned upper frame portion, as is clear at first glance in Fig. 4, but the details thereof will be omitted.

Examples are shown with commas added to the symbols corresponding to those in FIG.

However, the new frame 1 has a slightly different structure from the new frame 5, and there are also some structural differences in the reinforcing metal fittings 2 and the mounting metal fittings 25', especially the frame material 32' in the mounting metal fittings 25'. It has a reinforcing piece 33 to prevent it from being damaged when subjected to an external force, which is especially clearly shown in FIG.

In this Figure 4, 7A' is the indoor side engaging part of the new frame 7, and the mounting used in Figure 4 is the metal fitting 25.
' is shown in FIG. 6 (in addition to having a foundation bolt insertion hole 26A', the reinforcing piece 33 has a screw hole 33a).

The present invention relates to a renovated window frame in which a new window frame framed in a rectangular shape is fitted into a heavy window frame remaining in a building, and the old and new window frames are connected and fixed to each other. A band-like tongue piece having a rain protection function is provided on the outer periphery of the back of the frame, and the outdoor side surface of the tongue piece extends toward the building on the same plane as the outdoor side surface of the new upper frame new side frame. An L-shaped metal fitting that corresponds to the frame and the outdoor side end surface of the mouth side frame, and has a part that follows the tongue pieces of the upper frame and the side frame, and a part that follows the outer periphery of the new frame and the side frame. are attached to the outer periphery of the new window frame at predetermined intervals in the longitudinal direction of the frame, and in addition, metal fittings are fixed to the inner periphery of the upper frame and side frame of the heavy window frame, and this installation is carried out using metal fittings. and the metal fittings on the side of the new window frame are connected and fixed to each other, and further, the lower frame of the new window frame is fixed to the lower frame of the heavy window frame via a stand. As such, there are the following advantages.

Since the new window frame is installed using the remaining double window frame and is considered a refurbished window frame, the window opening area will be narrower to some extent compared to removing the double window frame. In addition to the basic advantage of being able to use it as a refurbished window frame with simple construction, the exterior surface of the tongue piece with a rain protection function installed on the outer periphery of the upper frame and side frame of the new window frame Since the chambers of the new frame and side frame extend on the same plane as the outer surface, there is an advantage that there is no difference in level at the joint between the new frame and the new frame.

Furthermore, since a plurality of L-shaped fittings each having a portion along the tongue piece and a portion along the outer periphery of the upper frame and side frame are attached to the outer periphery of the window frame, each of the tongue pieces, the upper frame and The rigidity of both side frames has been improved, and the new window frame, which has relatively poor shape retention, can be unified (it can be combined with the new window frame to create a refurbished window frame).

In addition, since the metal fittings and the above-mentioned L-shaped metal fittings are connected and fixed to the inner periphery of the upper frame and side frame of the double window frame, it is stronger than when installing a new window frame to the double window frame. Installation is possible, and in this way - along with the installation of the upper frame and side frames, the lower frame part is fixed through a stand, so the new window frame can be reliably installed as a whole. It can be used as a window frame, and since the outdoor side of the upper frame and side frame is closed off from the rain with tongue pieces, it has the advantage that separate mortar construction may not be necessary.
