In such a sash window, if the sash window is constructed by combining the window frame of (A) and the shoji having the heat insulating member of (b), the shoji is provided with the heat insulating member. Insulation performance can be improved as compared with a general sash. At this time, the cost of the heat insulating sash is higher than that of the general sash because the heat insulating member is interposed and processing is required. However, in the present invention, since only the shoji is used as the heat insulating frame, the window frame is also insulated. The cost can be reduced as compared with a conventional heat insulating sash constituted by a frame, and the cost can be suppressed even as compared with a general sash window, so that it can be provided at a cost commensurate with the improvement of the heat insulating performance.

Further, if a sash window is configured by combining the window frame of (A) and the sliding screen of (a), a general sash is configured.

The only difference is that the sash window 10 is different from the sash window 10 in that the sash window 5B is arranged. Therefore, FIG. 8 shows only the lower frame and lower frame portion of the sash window.

Each of the shoji screens 5A and 5B includes lower frames 73 and 74,
The upper frame, the left and right vertical frames, the outer mating frame, and the inner mating frame (not shown) are assembled in a rectangular frame shape. A single glass 75 is fitted to the inner peripheral surfaces of the frames 73 and 74 via a gasket 76. Here, the lower frames 73 and 74 of the sliding doors 5A and 5B, the upper frames and the vertical frames (not shown) have the expected dimensions in the indoor and outdoor directions to the respective frames 21 to 26 of the sliding doors 6A and 6B by the amount of holding the single glass 75. It is smaller than that. However, the dimension between the door rollers 32 of the sliding doors 5A and 5B is the dimension L2 between the rails 18 and 19, that is, the sliding doors 6A and 6A.
The dimensions are the same as those between the door rollers 32 of B.

Further, (A) a sash window in which the general window frame 2 is combined with (a1) the general single-sheet shoji 5 and (A) the general window frame 2
And (a2) the sash window in which the general multi-layered shoji is combined has the same configuration, and a description thereof will be omitted.

In the present embodiment, appropriate window frames 1 and 2 and shoji screens 5 to 7 are taken into consideration in consideration of the area and environment in which the building in which the sash window is to be installed, the location of the sash window in the building, and the like. Various sash windows 10, 40 in combination
70 and 80 are configured. For example, when the insulation performance is not so required in a warm region or when a sash window is installed on the south side of a building, the sash window may be configured by combining the general window frame 2 and the general single-panel sliding door 5. . If it is necessary to improve the heat insulating performance of the shoji by installing a sash window on the north side of the building, etc., the general window frame 2 may be combined with the general multi-layer shoji 6 to improve the heat insulating performance. In this case, a sash window 40 in which the heat insulating multi-layer shoji 7 is combined with the general window frame 2 may be installed.

On the other hand, in order to improve the heat insulating performance of the window frame, a heat insulating window frame 1 is used instead of the general window frame 2, and the sash window 1 in which each of the sashes 5, 6, and 7 is combined with the heat insulating window frame 1.
0, 70, and 80 may be provided. Among them, the sash window 80 in which the heat insulating window frame 1 and the heat insulating multilayer shoji 7 are combined has the highest heat insulating performance.

Further, the sliding doors 5 to 7 were originally provided with the window frames 1 and 2.
The sash windows in which the window frame 1 or 2 has already been installed may be replaced with sashes 5 to 7 as needed to change the heat insulation performance.

According to the present embodiment, the following effects can be obtained. That is, two types of window frames 1 and 2 and three types of shoji screens 5 to 7 are prepared, and these window frames 1, 2 and shoji screens 5 to 7 are freely combined and various sash windows 10 and 4 are prepared.
Since 0, 70, and 80 can be configured, a sash window having necessary heat insulation performance in each building can be easily configured. Therefore, in particular, only the window frame 1 is made of a heat insulating type like the sash windows 10 and 70 in which the heat insulating window frame 1 and the general sash screens 5 and 6 are combined, which is particularly effective in preventing dew condensation on the surface of the window frame 1. Insulation performance of the sash 7 that holds the glass 29 having a particularly large area is improved by using only the sash 7 as a heat insulating type, such as a sash window 40 in which the type and the general window frame 2 and the heat insulating multi-layer shoji 7 are combined. The type and the like can be appropriately selected.

Therefore, the sash windows 10, 40, 70, and 80 having six different levels of heat insulation performance can be formed by combining each of the window frames 1 and 2 and the sashes 5 to 7, and the sash windows can be configured as compared with the conventional case. It is possible to set windows having heat insulation performance in accordance with the installation positions of windows in each building or building. As a result, the insulated window frame 1 and the insulated multi-layered shoji 7 which are higher in cost than the ordinary window frame 2 and the shoji screens 5 and 6 can be used as much as necessary, and an inexpensive sash window suitable for the heat insulating performance. Can be provided. For this reason, the sash window which improved the heat insulation performance without increasing the cost so much can be used even in a region where a conventional sash window was not used in the conventional heat-insulating sash window because the cost was not justified. . Therefore, the cooling and heating effect in the building can be improved, energy can be saved, and the occurrence of dew condensation can be suppressed.

In addition, each of the shoji screens 5 to 7 has one of the window frames 1,
For example, even in a building where a single veneer sliding door 5 has been installed, a sash window in which the thermal insulation performance is changed by replacing the sliding door 5 with another sliding door 6, 7 later. Can be configured. In particular, since the sliding doors 5 to 7 can be removed from the window frames 1 and 2 originally, they can be easily replaced, and the heat insulating performance of the existing sash window can be easily and inexpensively changed.

Further, the expected dimensions of each of the sashes 5 to 7 are almost the same. Particularly, in the case of the heat-insulating multi-layer sash 7, by disposing the screw hole member 60 in the heat insulating materials 51 C to 54 C,
Since the same expected size as that of the general multi-layered shoji 6 can be used, common accessories such as the screen door 33 can be used, and the cost can be reduced accordingly.

The estimated dimensions of the window frames 1 and 2 are set to the dimension L1.
And the expected sizes of each of the shoji screens 5 to 7 are almost the same, so that the structure (fitting) on the skeleton side where the sash window is to be mounted, for example, the mounting structure for the working material inside the sash window and the mounting for the outer wall material Which window frame 1,
The combination of 2 and shojis 5, 6, and 7 can be made common. Therefore, in any combination of sash windows, design and construction can be simplified, workability can be improved, and costs can be reduced.

In addition, even when the types of sash windows to be installed on the south side and the north side in one building are made different depending on the required heat insulation performance, the mounting structure and design can be shared, and The property is good, and it is possible to construct a building with a uniform appearance and interior. Therefore, even in one building, it is possible to appropriately select and install an optimal sash window for each part of the environment such as the southern surface and the northern surface.

Further, in the heat-insulating window frame 1, the heat-insulating members 11C to 13C, which are continuous four times, are provided on the indoor side of the rails 16 to 19, that is, along the indoor side of the inner sashes 6B and 7B. 16 to 19 are outdoor members 11
A, 12A, even if each of the rails 16 to 19 is cooled by touching the outside air, the temperature of the room members 11B, 12B
Can be prevented from being transmitted to the heat exchanger, and the heat insulation performance can be improved. For this reason, in the heat insulating window frame 1, the occurrence of dew condensation can be suppressed as compared with the general window frame 2, and a more comfortable living space can be formed.

In addition, when the heat insulating member is disposed between the inner and outer rails, a part of the heat insulating member and the indoor member is exposed to the outside of the vehicle, so that a resin cover material or the like must be provided. Instead, the number of parts increases and the cost increases, and the cover material is adhered to the rail, so that the thickness of the rail increases by the amount of the cover material, and a shoji is formed according to the rail thickness. Must be different in structure between the shoji for the heat insulating window frame and the shoji for the general window frame.
Although sash windows of various combinations cannot be configured by switching to each other, in the present embodiment, the heat insulating members 11C to 11C are used.
Since the 13C is disposed at a position closer to the indoor side than the rails 16 to 19, a cover material is not required, the cost can be reduced accordingly, and the thickness of the rail in the heat insulating window frame and the general window frame is reduced. This is the same, so that various sash windows can be configured by appropriately combining each window frame and each shoji.

Further, each of the sliding doors 6 and 7 has a rail 16
Sealing material 59 in contact with the outdoor surface and vertical frames 13 and 43
Is provided, it is possible to prevent outside air from flowing into the room from between each of the sashes 6 and 7 and the rails 16 to 19, and to further improve the heat insulation performance. In particular, the insulating multi-layer shoji 7
In, by preventing the inflow of outside air with the sealing material 59, the indoor members 51B to 56B of the shoji 7 can be prevented from being cooled by the outside air, and the heat insulating performance of the shoji 7 can be further improved.

The present invention is not limited to the above embodiment. For example, the heat insulating window frame 1 is not limited to the above-described embodiment, and as shown in FIG. 9, an outdoor member 91 and a room member 92 made of a non-ferrous metal such as aluminum are separately formed, and are made of synthetic resin. It is also possible to use a heat insulating window frame 90 in which two plate-shaped heat insulating members 93 are arranged between the members 91 and 92 and are caulked and connected (B2).

As shown in FIG. 10, a (C1) heat insulating window frame 95 formed by joining an outdoor member 96 made of a non-ferrous metal such as aluminum and a wooden indoor member 97 which is a heat insulating member is used. You may. Further, as shown in FIG. 11, a (C2) heat insulating window frame 100 formed by joining an outdoor member 101 made of a non-ferrous metal such as aluminum and an indoor member 102 made of a synthetic resin such as polyvinyl chloride resin is used. You may.

In short, in the present invention, the heat insulating window frame includes a heat insulating member (a member made of synthetic resin such as urethane or wood) so that the temperature of the outdoor member is not transmitted to the indoor side. What is necessary is just to be comprised. When the heat insulating window frame is used for the sliding window, the indoor and outdoor rails 1 are used.
It is sufficient that the dimension between the cores 6 to 19 is shared by L2. Thereby, which window frame 1, 2, 90, 95, 100
Also, the shoji screens 5 to 7 can be attached. Furthermore, if the expected dimensions of the window frames 1, 2, 90, 95, 100 are shared by the dimension L1, the window frames 1, 2, 90, 95, 100
The mounting structure can be made common when mounting 100 to the skeleton, and the workability in construction can be improved.

Further, the insulating multi-layered shoji 7 is not limited to that of the above-described embodiment. As shown in FIG. 12, an outdoor member 111 and a room member 112 made of a non-ferrous metal are separately molded and made of a synthetic resin. The two plate-shaped heat insulating members 113 are attached to each member 111,
(B2) Insulated double-layered shoji screens 110 may be used.

Further, as shown in FIG. 13, a (c1) heat-insulating double-layered sliding door 115 composed of a non-ferrous metal outdoor member 116 and a wooden indoor member 117 may be used. Further, as shown in FIG. 14, the outdoor member 12 made of a non-ferrous metal is used.
1 and indoor member 12 made of synthetic resin such as polyvinyl chloride resin
(C2) heat-insulating double-layered shoji 120 may be used.

In short, the heat-insulating double-layered shoji has a heat-insulating member (a member made of synthetic resin such as urethane or wood) so that the temperature of the outdoor member is not transmitted to the indoor side. It should just be. Further, in the case where the heat-insulating double-layered sliding door is used for a sliding window, the distance between the doors of the indoor and outdoor sliding doors may be the same as the distance L2 between the rail cores of the window frame. Thereby, which shoji screen 5, 6, 7, 110, 11
5,120 can also be attached to the window frame. further,
If the expected dimensions of the shoji are made substantially common, some parts of the shoji do not interfere with the screen door 33, other members such as the screen door 33 can be shared, and the workability of construction can be improved. , Can be provided at low cost.

Further, in the above embodiment, the sash window used as the sliding window has been described.
The present invention can be applied to various sash windows having a window frame and a sliding door such as a sliding window other than a sliding window, a casement window, a sliding window, a vertical sliding window, an up-and-down window, an inside window, an outside window, and the like.

For example, as shown in FIG. 15, in order to form a vertical sliding window, (A1) a non-ferrous metal general window frame 132 and (B1) a mounting piece 131D attached to the frame are placed on the indoor side. And a heat insulating window frame 131 having a heat insulating member 131C, and (a3) a non-ferrous metal window frame incorporating a single-pane glass into a non-ferrous metal window frame; and (a4) a non-ferrous metal window. General double-layer shoji 1 with double-layer glass incorporated in the frame
36, (b2) Heat-insulating double-layer shoji 1 having heat-insulating member 137C
37 are prepared, and these window frames 131 and 132 are prepared.
May be combined with one of the shoji screens 135, 136, and 137 to form a vertical sliding window.

Here, one of the general sashes 135 and 136 is combined with the general window frame 132 to form the heat insulating window frame 1.
For 31, one of the shoji screens 135, 136, 137 is appropriately combined. In addition,
The combination of (A1) the general window frame 132 and (b2) the heat-insulating multilayer sash (shoji) 137 may be set as needed, and need not necessarily be set. That is, when the general window frame 132 and the heat-insulating multi-layered shoji screen 137 are combined, only the shoji screen is insulated. This is because the effect is small and not very practical.

In such a vertical sliding window, (A
1) General window frame 132 + (a3) general single-board shoji 135, (A
1) General window frame 132 + (a4) General multi-layer shoji 136, (B
1) Insulated window frame 131 + (a3) general single-sheet shoji 135, (B
1) Insulated window frame 131 + (a4) general multi-layer shoji 136, (B

Since these five (6) types of vertical sliding windows have slightly different heat insulation performances, an optimal sash window can be set according to the location of the building, the environment, the installation position of the windows, and the like.

In addition, other than the vertical sliding window, the same setting can be made in a single sliding window, a casement window, a sideways sliding window, a raising / lowering window, an inside opening window, an outside opening window, and the like. Here, when forming a heat insulating window frame in each of these windows, it is sufficient to use a semi-external type and provide a heat insulating member on the indoor side of the mounting piece to the frame. By providing the heat insulating member on the indoor side of the frame mounting piece in this way, heat conduction from the outdoor surface of the window frame can be reliably blocked by the heat insulating member, and the temperature decrease of the indoor surface of the window frame can be suppressed. In addition, the anti-dew performance can be improved. On the other hand, when inner and outer sashes such as sliding windows are provided as in the above-described embodiment, regardless of semi-external or external windows, the heat insulating member of the window frame extends along the indoor side of the inner sash. It may be provided.

Further, various window frames and shoji screens can be freely combined when configuring various windows, so that a common configuration set according to the type of window, for example, a window frame in a sliding window. In this case, the size between the rail cores and the size between the doors of each shoji may be the same, and the other windows may have the same width such as the expected width of each shoji.

Further, when constructing various sash windows including a sliding window and a vertical sliding window, whether or not a combination of a general window frame and a heat-insulating double-layered sliding door is allowed may be appropriately selected in practice. I just need.

Further, the parts other than the heat insulating member of each window frame and sash may be formed of a non-ferrous metal such as aluminum or stainless steel, and the specific material may be appropriately selected according to the environment around the building where it is installed. I just need.

(A), two types of window frames 1 and 2 (B) and (a1), (a)
2) and (b) are not limited to those having the three types of shojis 5 to 7. For example, (A) window frame 1, (a) non-ferrous metal shoji (a1 or a2 in the above embodiment) and (B) Two types of shoji (5 or 6) and 7 may be prepared, and the window frame 1 and the shojis 5 and 7 may be appropriately combined to form a sash window, or (B) a window frame. 2 and two types of shoji (5 or 6) and (7) of (a) and (b) may be appropriately combined to constitute a sash window, and (A) a non-ferrous metal window frame;
(B) a window frame having a heat insulating member, and (C) a window frame having a heat insulating indoor member (for example, window frames 95 and 100 of C1 and C2).
Three types of window frames, (a) a non-ferrous metal shoji, (b) a shoji having a heat insulating member, and (c) a shoji having a heat insulating indoor member (for example, shoji 115 and 120 of c1 and c2). A sash window may be configured by appropriately combining with a window frame. In short, the present invention provides at least two or more types of sashes and one or more types of window frames so that the heat insulating performance of the sash window can be made different by appropriately combining these sashes and window frames. What is necessary is just to be comprised.
