Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a renovated window frame in which an old window frame remaining in a building is fitted and a new and old window frame are connected and fixed to each other.

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 opening of the window frame of the building by so-called chiseling, and remove the old window frame. Previously, the method used was to expose the reinforcing bars and install the new window frame using these reinforcing bars (after the hardening work, it was the same as new construction work).

However, with the above-mentioned conventional construction method, not only is the work large-scale, but the construction costs are high, such as the need to set up work scaffolding outdoors, and there are other reasons such as the generation of noise and dust during the work. This has many disadvantages, such as restricting the use of buildings during work.

From this perspective, Sweet'5 Architect is a window frame renovation method that uses the old window frame and attaches a new window frame to it.

However, the publication states that when renovating window frames,
Because arrows were shot and welded, there was a risk that the renovated window frames would sometimes become sticky.

Therefore, the present invention uses a simple anchor metal fitting for the upper frame portion of the renovated window frame, and uses the anchor metal fitting to strengthen the rain closing portion of the renovated window frame, and to maintain a temporarily “fastened” state. By fixing it to the old window frame side and then fixing it, the renovated window frame can be installed with good alignment, and the new lower frame can be attached to the lower frame part through the mounting base fixed to the old lower frame. They succeeded in developing a refurbished window frame that supports the window from below and restricts its movement indoors.

Hereinafter, as an example of a specific configuration of the present invention, the first example will be described in the case where a new window frame made of aluminum is attached to an old window frame made of iron.
This will be explained based on FIGS. 4 to 4.

Fig. 1 shows a correct view of a window renovated using the device of the present invention, as seen from the indoor side, and Fig. 2 shows ■-■ of Fig. 1.
A vertical cross-sectional side view of the upper Azusa portion along the line is shown, and FIG. 3 shows a vertical cross-sectional side view of the lower frame portion along the line ■-■ in FIG.
FIG. 4 shows a cross-sectional plan view of the vertical frame portion taken along line IV--IV in FIG. 1.

In each figure, 1, 2, and 3 indicate the upper, lower, and vertical frames of the old iron window frames that are already installed on the building base 4, and 5 and 6
．． 7 shows the upper frame, lower frame, and vertical frame of the new aluminum window frame to be updated.

In existing old iron window frames, the upper frame 1 and the vertical frame 3 are quite solid, but the lower frame 2 is generally deteriorated due to rainwater, etc.

According to the present invention, the upper frame of the new window frame5. Lower frame 6. Vertical frame 7
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 that has already been framed is fitted into the old window frame that remained without being removed from the building base 4, and is firmly attached to the building base 4 using this old window frame. .

In the case of this embodiment, the device of the present invention is employed in the relatively strong upper vertical frame portion, and a different attachment device is employed in the aging lower frame portion.

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

A mounting base 8 is attached to the old lower frame 2, which is a steel plate bent into a σ-shaped cross section so as to have a rising portion 8a on the front edge, a rising portion 8b higher than the rising portion 8a on the rear edge, and a lip 8c on the upper end of the rising portion 8b. This mounting base 8 is placed on the top of the frame, and the mounting base 8 is made of a through material (a through material refers to a material whose length spans the entire length of the frame, and a short piece material refers to a short material that does not span the entire length of the frame; It is also called in the description.

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

The mounting base 8 has a steel short piece 10 for setting the new lower frame 6 in a predetermined position in cooperation with a rising part 8b, and a rising part for attaching an aluminum decorative frame 13 which is a through material. A short steel piece 11 attached to the lower part of the front wall 8a and a short piece 12 for attaching the aluminum frame material 14, which is a through piece, are placed at appropriate intervals along the longitudinal direction of the mounting base 8. A plurality of pieces are welded in advance, and the lower end of the decorative frame 13 is attached to the short piece material 11 with the rivet 1.
5 is pre-fixed.

After the mounting base 8 is fixed onto 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 rivets 16 and 17 can be driven only from the outside.
and caulking material 1 in the gap on the outdoor side.
9.20 is loaded, and the picture frame material 14 is fixed on the indoor side with rivets 18. A rubber gasket 21 is interposed between the lower part of the picture frame material 14 and the base 4, and the lower frame part is attached to the frame material 14. Renovation is completed.

Here, the new lower frame 6 is supported from below by the mounting base 8 fixed to the old lower frame 2, and the rising portion 8b restricts the lateral movement of the new lower frame 6 in the indoor direction.

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

The new upper frame 5 is an extruded aluminum member, and has an engaging part 5A including a groove on the indoor side (right side in the figure) of its back (side corresponding to the base 4), and has a rain cover function on the outdoor side. In this embodiment, a tongue 22 as an external frame having a shape is extruded in one piece and extends towards the building base 4.

In this embodiment, a groove-shaped airtight material fitting part 22B that opens toward the indoor side is formed at the extending end of the tongue piece 22, and an engaging part 22A is formed on the outdoor side of the fitting part 22B. has been done.

The airtight material fitting portion 22B corresponds to the outdoor end surface of the old upper frame 1, and the elastic airtight material 24 fitted to the fitting portion 22B is in contact with and supported on the outdoor end surface of the old upper frame 1. A water leak prevention body 28 made of caulking material is filled between the extending end portion and the building base 4 via a back-up material over the entire longitudinal length of the frame.

In this embodiment, the water leakage prevention body 28 and the elastic airtight material 24 are configured to exhibit a double sealing effect.
If the water leak prevention function of 8 is to be completed, the elastic airtight material 24 may be omitted in some cases.

A metal fitting (so-called anchor metal fitting) as an L-shaped bent object made of steel is installed on the back of the new upper frame 5. In this embodiment, the metal fitting 23
A plurality of the new upper frame 5 are provided so as to be slidable in the longitudinal direction of the new upper frame 5 while being engaged with each other in the indoor/outdoor direction.

That is, in this embodiment, the metal fitting 23 has a rising portion 23a formed on the indoor side through two slits as shown in FIG. The device is arranged so that the rising portion 23a is engaged with the engaging portion 5A in the indoor direction, and the outdoor rising portion 23c of the metal fitting 23 is engaged with the engaging portion 22A of the tongue piece 22.

The anchor fitting 23 has an L-shape having a part along the band-shaped tongue piece 22 having a rain protection function and a part along the outer periphery of the new upper frame 5. This helps to increase the rigidity of the tongue piece 22 when fitted.

In addition to this embodiment, the metal fittings 23 can be placed in a so-called floating shape on the new upper frame 5 to form a locking device.

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 old upper frame 1 by welding or by using foundation bolts 26.

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

The mounting bracket 25 has a groove-shaped one side wall 25a that is longer than the opposing wall 25b, and has a cross section in which the tip of the one side wall 25a is raised up and the metal fitting with a lip 25c is laid down. The molds are disposed in the same number as the metal fittings 23 and are located at a position 25d corresponding to the web.
A bolt insertion hole 31 is formed in the hole 31, and the hole 31 side is located toward the outside.

The new upper frame 5 is installed with the elastic airtight material 24 of the tongue piece 22 in contact with the outdoor end surface of the old upper frame 1, and in this state, the rising portion 23a of the metal fitting 23 and the web equivalent position of the mounting metal fitting 25 are attached. 25d, fasten the metal fittings 23 of the new upper frame 5 and the mounting metal fittings 25 using a connecting means, such as a tension bolt 27, inserted from the side corresponding to the web 25d,
The new upper frame 5 is fixed onto the old soil 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 to the interior side with the backing 30 and the rivets 29 as shown, and the renovation is completed.

At this time, the bolt insertion holes 31 of the mounting bracket 25 are formed into vertical or horizontal matching holes, so that the bolt insertion hole 31 of the mounting bracket 25 is inserted into the hole 31 to connect the anchor bracket 23 and the mounting bracket 25.
Temporarily tighten the bolts 27 in the range of the bolt insertion holes 31,
Alternatively, after adjusting the position of the new upper frame 5 by sliding the anchor metal fittings 23, the final fixing can be performed.

Next, regarding the vertical frame part, as it is clear at first glance in Figure 4, this part has the same basic structure as the above-mentioned upper frame part, so we will omit the details and refer to Figure 2. In the example, a "comma" is added to the corresponding symbol.

However, the new vertical frame T has a slightly different structure from the new upper frame 5, and the anchor fittings 23' and the mounting fittings 25' also have some structural differences.In particular, the mounting fittings 25' have a frame material 32. In order to protect it from damage when it is subjected to external forces, it has a reinforcing piece 33', which is especially clearly shown in FIG.

In the embodiment shown in FIG. 4, 7A' is the indoor side engaging portion, and 26A' in FIG. 6 is the foundation bolt insertion hole.

That is, in the embodiment shown in FIG.
(The tongue piece 22 becomes a piece at this time), and a rain cover 36, which is an extruded aluminum material with a Z-shaped cross section, is superimposed and fixed to the outside of the tongue piece 22 via screws 35, A water leak prevention body 28 is filled between the cover 36 and the building base 4.

In this embodiment, the elastic airtight material 24 is attached to the L-shaped through-piece 1A attached to the outdoor end surface of the old upper frame 1, and the mounting bracket 25 has its base 25A spaced apart indoors and outdoors. It is fixed with screws 26, etc. across the former Kami-Azusa-ma 1, which was exposed.

Further, the metal fitting 23 of this embodiment is fixed to the new upper frame 5 with screws 34.

Although this embodiment is shown using an upper frame portion, this can also be applied to a vertical frame portion.

Moreover, FIG. 7 shows another example of the upper frame part, in which the L-shaped through member 1
The only difference from FIG. 2 is that A is attached to the outdoor end surface of the old upper frame 1, and the rest is the same, so common parts are indicated by common symbols.

The embodiment shown in FIG. 7 is particularly useful when the exposed portion of the old upper frame 1 has an uneven shape on the outdoor end surface, and this embodiment can also be applied to the vertical frame portion.

The present invention provides a renovated window frame in which a new window frame is fitted into an old window frame that remains in a building and the old and new window frames are connected and fixed to each other. The mounting bracket fixed to the inner periphery and the anchor bracket attached to the outer periphery of the new Azusa are temporarily fixed and then finally connected and fixed by the connecting means, and the old and new parts are connected through the mounting bracket and the anchor bracket. The window frames are fixed to each other, and the anchor metal fittings are L-shaped with a part that increases the rigidity of the tongue piece for closing the rain from the inside side, which is formed as a strip on the outside of the Shinjo Azusa. In the lower frame part of the old and new window frames, the new lower frame is connected and fixed to the mounting base fixed to the outer periphery of the old lower frame, and the mounting base supports the new lower frame from below and supports the lateral direction in the interior direction. Since it relates to a renovated window frame characterized by being provided with a portion that restricts movement, it has the following advantages.

The present invention is directed to a renovated window frame in which a new window frame is fitted into an old window frame that remains in a building, and the old and new window frames are interconnected and fixed, so the advantages of this renovated window frame are maintained. be able to.

While maintaining these advantages, the refurbished window frame of the present invention has the following advantages.

A new mounting bracket is separately fixed to the old upper Azusa, and the anchor bracket attached to the outer periphery of the upper Azusa of the new window frame is connected and fixed to this mounting bracket, so the anchor bracket can be directly attached to the old upper frame main body. It can be installed more firmly than those that are fixed.

Moreover, since the mounting fittings and the anchor fittings are temporarily fastened and then permanently fastened, their positions can be adjusted.

In addition, since the anchor fittings have a part that increases the rigidity (rigidity) of the rain closing tongue of the new upper frame, it is possible to make a renovated window frame that matches even if its shape retention is relatively poor.

In this way, the upper part is designed for easy installation, while the lower frame part supports the new window frame from below and restricts the new window frame from moving laterally in the room. Even though it is a renovated window frame, it can be made to the same extent as a new window frame.

In addition, the new window frame is attached to the old window frame using new members in both the upper frame and lower frame parts, using the above-mentioned mounting brackets in the upper frame part and via the mounting base in the lower frame part. Therefore, it is possible to provide a renovated window frame in which the new window frame is securely attached to the old window frame even if the old window frame has a weak portion.

Furthermore, in the upper part, the mounting bracket is fixed to the inner periphery of the surrounding frame, and the anchor fitting attached to the outer periphery of the new window frame is fixed to this mounting bracket, so the gap between the old and new window frame can be filled with the upper part. Even if the window frame is made as narrow as possible, the connection and fixing force between the old and new window frames can be ensured, and this ultimately means that the area of the renovated window frame that is exposed to light and air can be made as large as possible.

In addition, the mounting base, which has a part that supports the new window frame from below and a part that restricts lateral movement in the indoor direction, is not attached to the upper part, which is relatively difficult to work on, but to the lower part, which is relatively easy to work with. , the mounting base can be installed accurately, and it can sufficiently resist the lateral movement of the new window frame in the indoor direction, that is, the wind resistance, and even if the old frame has a weak part in the lower frame part. Since the upper Azusa part is secured with mounting hardware and anchor metal fittings, the wind resistance of the new window frame can be mainly considered for the lower frame part, and only anchor metal fittings are used for the lower frame part. It is possible to provide a renovated window frame that has overall wind resistance comparable to that of a new window frame.
