Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for replacing a window frame, and more specifically, the present invention relates to a device for replacing a window frame. Using the frame,
The present invention relates to a technique for attaching a new window frame to be replaced, and particularly to a device for attaching a new window frame to an old 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. Recently, however, the time has come to replace the window frames with new ones.

By the way, when replacing a window with a new window frame, aluminum window frames have been commonly used in recent years.

Therefore, even if the material of the new window frame is iron or the above-mentioned aluminum, the replacement 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. The conventional method is to expose the reinforcing bars and use these reinforcing bars to install the new window frame (after the hardening work, it is the same as new construction work).

However, with the above-mentioned conventional construction method, not only does the work require a large scale assembly, but the construction costs are high, such as the need to set up work scaffolding outdoors, and the work also generates noise and dust. For this reason, there are many disadvantages such as restrictions on the use of buildings during work.

This invention was created to solve these problems, and its purpose is to eliminate the need for accessory equipment such as work scaffolding during replacement work, and to eliminate the need for large noise and dust. To provide a device for attaching a new window frame to an old window frame, with which replacement work can be carried out easily and safely in a short time.

In addition, in the present invention, the new window frame that is fitted into the old window frame has relatively poor shape retention, and in particular, the mounting U device has been improved to improve the poor shape retention of the tongue piece that has a rain cover function. It is on offer.

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 the diagram of FIG.

. Next, we will discuss the second part of the upper frame in which the device of the present invention is adopted.
This will be explained in detail based on the diagram.

The new upper frame 5 is made of extruded aluminum material, and a tongue piece 22 that functions as a rain cover (also referred to as an external frame) is integrally extruded on the outer periphery of the back toward the outside.

This tongue piece 22 extends toward the building base 4, and an airtight material fitting part 22B with a U-shaped cross section is provided on the indoor side of the extending end corresponding to one end surface of the old upper frame 1. is formed in the shape of a groove in the longitudinal direction of the frame, and an elastic airtight material 24 is fitted into the fitting portion 22B over the entire length of the frame.

Furthermore, an engaging portion 22A is formed on the tongue piece 22 near the airtight material fitting portion 22B, in this embodiment, on the outdoor side of the fitting portion 22B.

A plurality of steel metal fittings 23 are provided on the back of the new upper frame 5 at predetermined intervals in the longitudinal direction of the frame, and the metal fittings 23 are L-shaped bent pieces as shown in FIGS. 2 and 5, and one end of the metal fittings 23 is The other end of the rising portion 23c has a rising portion 23a lower in height than the rising portion 23c through two slits, and the remaining portion 23b of the rising portion 23a is connected to the indoor groove of the new upper frame 5. 1, and the rising portion 23a is engaged with the engaging portion 5A including the groove portion.
”-, and the outdoor side standing portion 23c touches the tongue piece 22.
The metal fitting 23 is slidable in the frame length direction and is engaged in the frame 1 direction.

That is, the metal fitting 23 has an L-shape having a part along the tongue piece 22 and a part along the outer periphery of the new frame, and one end thereof, in this example, the end of the rising part 23c engages with the engaging part 22A of the tongue piece. , the other end, in this example, the remaining part 23b engages with the indoor side groove part of the new seventh frame 50, and the tongue piece 22 is strengthened here together with the fitting part 22B, and the new upper frame 5 is strengthened to maintain its shape. It improves sexuality.

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 the tip of the one side wall 25a is raised up, and a lip 25c is attached. The new upper frame 5 is provided with bolt insertion holes 31 in the same number as the metal fittings 23 and is provided with bolt insertion holes 31 at the web-equivalent positions 25d, with the hole 31 facing toward the outside. The elastic airtight material 24 is attached to the tongue piece 22 in a state in contact with the outdoor end surface of the old upper frame 1, and in this state, between the rising part 23a of the metal fitting 23 and the web equivalent position 25d of the mounting metal fitting 25, , connect the metal fittings 23 of the new upper frame 5 and the mounting metal fittings 25 to the new and old upper frame 5 using the connecting means inserted from the web equivalent side 125d - the tension bolt 27 as an example.
, 10 intervals, and the new upper frame 5 is connected to the old upper frame 1.
fixed on top.

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 rivets 29 with the backing 30 inserted, and the replacement is completed.

In this case, it is more convenient to make the insertion holes 31 of the bolts 27 of the mounting fittings 25 into vertically elongated holes 2 for vertical alignment.

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. An example of 1 to t7 is shown by adding a comma to the corresponding code.

However, the new vertical frame 7 having the engaging portion 7A' has a slightly different structure from the new upper frame 5, and also has a reinforcing metal fitting 23' and a mounting metal fitting 25.
' also has some structural differences, especially the mounting bracket 25' has a reinforcing piece 33 to prevent damage to the frame material 32' when it receives external force. The reinforcing piece 33 has a screw hole 33a, and 26A' in FIG. 6 indicates a foundation bolt insertion hole.

Furthermore, FIG. 7 shows another embodiment of the present invention in the upper frame portion, in which a member 1A having a cross-section shape is attached in advance to the outdoor side of the old upper frame 1. This is effective when the outdoor end surface of the frame 1 is uneven.

In addition, in each of the above implementations, the metal fitting 23 provided on the outer periphery back of the new window frame overlaps with the outer periphery back, but it engages with the groove formed on the outer periphery of the new window frame and floats from the so-called outer periphery back. It may also be one that is held in the same shape.

As described above, the present invention provides a renovated window frame in which a new window frame framed is fitted into an existing old window frame that remains in a building, and the old and new window frames are connected and fixed to each other. A strip-like tongue piece having a rain protection function is integrally extended in the longitudinal direction of the frame on the outer periphery of the back of the edge. An elastic material fitting portion into which an elastic material such as rubber or resin is fitted is integrally formed as a groove over the entire longitudinal direction of the frame, and a groove-shaped engaging portion is formed in the vicinity of the elastic material fitting portion; Further, L-shaped metal fittings having a portion along the band-like tongue piece and a portion along the outer periphery of the new window frame are provided at intervals slidable in the frame length direction, and one end of the metal fitting is attached to the engaging portion. The ends are engaged with the indoor grooves 1c on the back of the outer periphery of the new window frame, and a mounting bracket is fixed to the inner periphery of the old frame, and the mounting brackets and the aforementioned brackets are connected and fixed to each other. Since the present invention relates to a device for attaching a new window frame to be replaced with an existing old window frame, the present invention has the following advantages.

1) Since the old window frame remains, the troublesome so-called chiseling work to attach the old and new window frames can be omitted, and the old and new frames can be easily connected.

2) The mounting bracket is fixed to the old window frame, and the new window frame is installed using the mounting bracket as a reference, so this can increase the installation strength compared to attaching the new window frame directly to the old window frame. can.

3) The new window frame has a strip-like tongue piece that has a rain protection function integrally extended on the outside edge of the window frame, and the rigidity of the tongue piece tends to be insufficient. Since the elastic-closing material fitting part is integrally formed in the shape of a groove through the protrusion protruding toward the interior of the room on the edge side, the rigidity of the tongue piece can be increased evenly. Coupled with the formation of the engaging portion, the rigidity can be increased, and therefore, even if the fixing force for fixing the L-shaped metal fitting and the mounting bracket by the connecting means is increased, deformation of the tongue piece etc. can be prevented.

4) Furthermore, the L-shaped metal fitting has a part along the tongue piece and a part along the new window frame, one end of which is engaged with the engaging part of the tongue piece, and the other end is engaged with the indoor side groove part of the new window frame. This allows the new window frame to maintain its shape sufficiently, and the L-shaped metal fittings, which have the function of ensuring the new window frame's shape retention, are connected to the mounting metal fittings. Therefore, the L-shaped metal fitting has a multifunctional function of having both a frame-like function and a connecting function.This allows the structure to be simplified and the connection to be made quickly and easily.
