DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sash structure for refurbishment of an existing sash and a method of remodeling the sash.

[0002]

2. Description of the Related Art In recent years, a sash structure including a metal outer frame such as an aluminum sash and a shoji frame in which a plate member such as glass is fitted has been widely used as a window of a general house. Recently, air conditioning has been used to increase the efficiency of cooling and heating,
That is, in order to save power, a sash structure is expected to have high airtightness and a heat insulating effect.

For example, a structure in which an elastic member is interposed in a contact area between a shoji frame and an outer frame, a sash structure for a double window including a heat insulating material, and the like are widely used in new houses. On the other hand, in relatively old houses, wooden windows are still used, and even windows having an aluminum sash structure are often old types.

[0004]

However, such a wooden window or an old type sash structure does not have a structure in consideration of airtightness and heat insulation as described above, so that the effect of cooling and heating is small or the window glass is frequently used. It is necessary to renovate to a new sash structure due to condensation.

[0005] However, the renovation of a conventional window involves removing an old window and then installing a new sash window, which is not only time-consuming but also takes time when removing the existing outer frame fixed to the outer wall. The interior can be damaged. This problem becomes more serious as the number of windows is increased for a single house.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a sash structure that can be easily remodeled without damaging the exterior or interior.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A sash structure for refurbishment according to the present invention will be described with reference to the drawings of the embodiment. FIG. 1 shows a case where an existing window is newly refurbished to a single-opening double-glazed window. In the vertical sectional view and the transverse sectional view of FIG. 1, an existing outer frame 1 made of an aluminum alloy is inserted into a window opening H provided in an outer wall W.
(First outer frame) remains fixed, a new outer frame 2 (second outer frame) is newly attached to the inner periphery of the existing outer frame 1, and a new shoji 3 (second outer frame) is attached to the new outer frame 2. 2), and the entire outer periphery of the existing outer frame 1 is covered with a frame 6 from the outdoor side.

As shown in FIG. 3, the frame 6 is formed by assembling an upper horizontal frame member 6a, a lower horizontal frame member 6b, a right vertical frame member 6c, and a left vertical frame member 6d, so that each frame member 6a, 6b, 6c, 6d is assembled. Not only can it be stored and transported with reduced bulk, but also can be assembled at the construction site. In particular, when the forehead members 6a, 6b, 6c, and 6d are cut from a common extruded shape, a connecting groove 17 is provided inside the extruded shape,
The ends of the forehead members 6a, 6b, 6c, 6d are cut at 45 degrees, the cut surfaces are butted against each other, and the L-shape is inserted across the connecting groove 17 at the butted end. Connecting bracket A
Is fixed, the frame 6 can be provided at low cost.

The new outer frame 2 is composed of an upper frame member 2a, a lower frame member 2b, and left and right vertical frame members 2c and 2d.
If each frame material 2a, 2b, 2c, 2d is made of synthetic resin,
The heat insulating effect of the sash structure can be enhanced. New Shoji 3
The glass plate 5 is inserted into the inside of the shoji frame 4. The upper frame, the lower frame, and the right and left vertical frames forming the shoji frame 4 are made of synthetic resin. If the two glass plates are opposed to each other, the heat insulating effect of the sash structure can be enhanced.

The frame 6 is provided with a heat insulating material 9 in a space defined by an inner peripheral wall 7 interposed between the existing outer frame 1 and the new outer frame 2 and an outer peripheral wall 8 covering the outdoor exposed portion of the existing outer frame 1. The heat insulating material 9 is made of, for example, glass wool or foam resin having elasticity, and is provided over the entire periphery of the frame 6. Therefore, the frame members 6a, 6b, 6c, 6d of the frame 6 are formed of an aluminum alloy. However, transmission of the outside air temperature from the frame 6 is interrupted. When the inner peripheral wall 7 of the picture frame 6 is inserted between the existing outer frame 1 and the new outer frame 2 and the outer peripheral wall 8 is fixed to the outer wall W by screws, the outdoor exposed portion of the existing outer frame 1 becomes the inner peripheral wall 7 and the outer peripheral wall. 8, the appearance of the sash structure after renovation is completely new.

The inner peripheral wall 7 of the picture frame 6 extends from the outer peripheral wall 8 to the inside of the room. A plurality of cut grooves 7a are provided on the inner surface of the extension of the inner peripheral wall 7 in parallel with the longitudinal direction. 7a
The length of the inner peripheral wall can be adjusted by cutting or cutting along. Notch groove 7 on the inner surface of the extension of inner peripheral wall 7
When the ridge 7b is provided with the ridge 7b which is continuous with the cut groove 7a, the cutting or cutting in the cut groove 7a is facilitated. Even if the cut grooves 7a and the ridges 7b are provided at regular intervals,
The same purpose is achieved even if provided at arbitrary intervals.

Next, a method of remodeling the sash structure for refurbishment according to the present invention will be described below. An existing shoji (first shoji, not shown) is cut from the existing outer frame 1 fixed to the window opening H of the outer wall W. It comprises a step of removing, a step of attaching the new outer frame 2 to the inner periphery of the existing outer frame 1, and a step of covering the existing outer frame 1 with the frame 6 from the outdoor side. The dimensions of the existing window are measured in advance, and a new outer frame 2 having an outer peripheral shape that can be built in the inner periphery of the existing outer frame 1 in a Kendon manner, and a shoji frame 4 fitted to the new outer frame 2 are provided. A frame 6 for covering the new shoji 3 and the existing outer frame 1 is configured in advance. For example, as shown in FIG. 3, an upper horizontal frame member 6a, a lower horizontal frame member 6b, a right vertical frame member 6c, and a left vertical frame member 6d are connected to each other. Into a rectangular shape.

First, the existing shoji is removed from the existing outer frame 1. Next, as shown in FIG. 2, a new outer frame 2 is built in the existing outer frame 1 in a Kendon manner, and this is then inserted into the window opening H.
Around the area. Next, the picture frame 6 is attached. At this time, a heat insulating material 9 is filled in the space of the picture frame 6, the picture frame 6 is put on the existing outer frame 1 from the outdoor side, and the outer peripheral wall 8 is fixed to the outer wall W by screws. The heat insulating material 9 appropriately fills the space between the inner peripheral wall 7 of the frame 6 and the outer peripheral wall 8 of the existing outer frame 1 due to its bulkiness. It is desirable that the new shoji 3 be provided after the new outer frame 2 is attached.

After the new outer frame 2 and the frame 6 are attached, the gap between the inner peripheral wall 7 of the frame 6 and the new outer frame 2 and the gap between the outer peripheral wall 8 of the frame 6 and the outer wall W are filled with the caulking material C, respectively. If it is a sash structure by renovation, the airtightness will be improved. That is,
By caulking the inner peripheral wall 7 of the picture frame 6 and the new outer frame 2, the existing outer frame 1 is completely isolated from the outside air, so that the transmission of the outside air temperature by the existing outer frame 1 is completely eliminated.

The above steps complete the retrofit to a new sash structure. In this renovation method, unlike the conventional renovation,
Since the labor for removing the existing outer frame 1 is not required, the total work time is shortened accordingly, and a difficult technique of removing the existing outer frame 1 while minimizing damage to the outer wall W and the interior is required. And relatively easy work.

In the above embodiment, the new outer frame 2
The side of the double glass shoji 3 is supported as a
Although the one that can be opened and closed on one side has been shown as a center, the present invention is not limited to the embodiment, for example, a casement window, a sliding window, a raising and lowering window, a rotating window, a falling window, a fitting window, etc. Various windows and doors can be used as long as they can be accommodated in the inner periphery of the existing outer frame 1. Further, the frame 6 is not limited to be made of an aluminum alloy, but may be made of another metal material or a synthetic resin.

[0024]

According to the retrofit sash structure of the present invention, as described above, there is no need to remove the existing first outer frame, that is, the first outer frame is left, and the first outer frame is removed. Since the new second outer frame is attached to the inner periphery, the outer wall and the interior are not damaged due to the removal of the first outer frame.
In addition, after the second outer frame is attached, the first outer frame is entirely covered with a picture frame from the outside of the room, and is completely concealed.

The frame in which the inner peripheral wall of the frame member protrudes from the outer peripheral wall toward the indoor side and the length of the inner peripheral wall can be adjusted according to the mounting position of the first outer frame corresponds to various first outer frames. Can be used. That is, even if the first outer frame is internally attached to the inner periphery of the window opening, or externally attached to the outdoor side of the window opening, the first outer frame is further attached to the inner periphery of the window opening. It can be used even if it is a semi-external attachment that extends over the outdoor side.

Further, according to the remodeling method of the present invention, since the step of removing the existing first outer frame is not required, the labor and cost are reduced by that much, and the work process is greatly reduced as compared with the conventional remodeling. This has the effect of simplification. Since the gap between the frame and the second outer frame and the gap between the frame and the outer wall are filled in the caulking process, the airtightness and the watertightness are also improved.
