A sash window combined with a general shoji 7, as shown in FIG. 8, a sash window 80 in which (B) a heat insulating window frame 2 and (a) a heat insulating profile shoji 5 are combined, and (B) a heat insulating window frame 2 ( c) A sash window combining the general shoji 7 can be constructed. Since the configuration of each of these sash windows is similar to that of each of the sash windows 10 and 40, description thereof will be omitted. In addition, (c) general shoji 7
As shown in FIG. 1, it is a general shoji that each frame of the outer shoji 7A and the inner shoji 7B is made of a non-ferrous metal such as aluminum, and the dimensions L1 to L7 are also the sash windows 10 and 4 (not shown).
It is the same as 0.

In the present embodiment as described above, an appropriate window frame 1, in consideration of the area and environment where the building where the sash window is installed, the installation location of the sash window in the building, the design, etc. are taken into consideration.
2 and shoji 5-7 combined to each sash window 10, 4
0,80 may be configured. For example, when it is desired to select the color of the shoji screen according to the color of the inner wall, (b) the aluminum resin composite shoji screen 6 using the resin interior members 61B to 68B having a relatively high degree of freedom in coloring can be selected. Good. Further, in selecting the window frame, if the heat insulation performance is important, (A) the heat insulation window frame 1 may be selected, and if the heat insulation performance is not so required in a warm region,
(B) The heat insulating window frame 2 may be selected.

Although it is difficult to replace the window frames 1 and 2 after construction, the heat insulation performance can be adjusted by replacing the shoji 5 to 7, and it is necessary to replace the window frames 1 and 2 after construction. Does not really matter because it is not really high.

Further, the shoji 5 to 7 are originally the window frames 1 and 2.
Since it is removable, the heat insulating performance may be changed by appropriately replacing the shoji 5 to 7 in the sash window in which the window frame 1 or 2 is already installed.

According to this embodiment, the following effects can be obtained. 1) Two kinds of window frames 1 and 2 and three kinds of shoji 5 to 7 are prepared, and each of the window frames 1 and 2 and shoji 5 to 7 is freely combined to make six kinds of sash windows 10 and 40. , 80, the design, in particular, the internal design and various sash windows having different heat insulating properties can be easily configured. For this reason, it is possible to easily set the sash window of the design or the installation position of the window in each building and the heat insulation performance and the design according to the request of the owner, as compared with the related art. As a result, it is possible to use the heat insulating window frames 1 and 2 and shoji 5, 6 which are higher in cost than the general window frames and shoji made of only non-ferrous metal such as aluminum, and to use the minimum necessary amount, and the heat insulation performance is improved. It is possible to provide an inexpensive sash window suitable for. Therefore, even in a region where a general sash window is used because the conventional heat insulating sash window does not match the cost, the sash window having improved heat insulating performance can be used without increasing the cost so much. Therefore, it is possible to improve the cooling and heating effect in the building and save energy.
The occurrence of dew condensation can also be suppressed.

2) Which window frame 1 or 2 is used for each shoji 5-7.
Since it can be attached also to the sash, for example, even in a building to which the heat insulating profile shoji 5 was attached, the shoji 5 was replaced with another shoji 6 or 7 to change the heat insulating performance or design. The window can be configured. In particular, shoji 5
Since 7 is originally designed to be detachable from the window frames 1 and 2, it can be easily replaced, and the heat insulation performance of an existing sash window can be easily and inexpensively changed.

3) When replacing shoji 5-7, the window frame 1,
Since No. 2 does not need to be replaced, replacement work can be performed easily and cost can be reduced. In addition, it is not necessary to manufacture a dedicated window frame for each shoji 5-7, and two types of window frames (either one of the window frames 1 and 2 may be used if there is no need to change the heat insulation performance) are prepared. Since it suffices, the number of types of parts can be reduced and cost can be reduced.

4) The exposed surface portions of the window frames 1 and 2 are covered with the heat insulating covers 201 to 206 and 221. Therefore, dew condensation on the window frames 1 and 2 can be suppressed, and the window frames 1 and 2 can be prevented from condensing. The heat insulation performance can also be improved.

5) The upper frames 11 and 41 and the vertical frames 13 and 43 are
Since the heat insulating covers 201, 221, 205, 206 are not extended to the interior surface of the frame 210, 212, the heat insulating covers 201, 221, 205,
The upper frames 11, 41 and the vertical frames 13, 43 do not come into direct contact with the portions of the frame 210, 212 of 206 which are extended to the interior surface,
Heat transfer from the frame material can be suppressed. Therefore, even if the upper frames 11, 41 and the vertical frames 13, 43 are cooled by the outside air, the heat insulating covers 201, 221, 205, 20 are provided.
Since it is difficult for heat to be transferred to the indoor end of 6, it is possible to suppress the occurrence of dew condensation.

6) On the other hand, the lower frame 12 of the heat insulating window frames 1 and 2 is
The heat insulating member 1 extends to the interior surface of the set plate 211.
Since heat transfer between the outdoor member 12A and the indoor member 12B is suppressed by interposing 2C, the heat insulating cover 203 is hardly cooled by the indoor member 12B, and the occurrence of dew condensation can be suppressed. Furthermore, the heat insulating cover 20
3 is provided with a soft resin fin 203A,
The fin 203A can be brought into contact with the setting plate 211 to seal the gap. Therefore, the air in the room is
Can be prevented from flowing into the indoor member 12B side, and the occurrence of dew condensation can be further suppressed.

7) Heat insulating covers 201 to 206, 221
Is extended to the interior surface of the frame 210, the set plate 211, and the frame 212, the contact line between the frame 210, the set plate 211, the frame 212, and the window frames 1 and 2 has the heat insulating cover 20.
Since it is covered with 1 to 206 and 221 and is not exposed to the inside of the room, the design can be improved.

8) Since the size L2 from the door roller 32 of the outer shoji 5A, 6A to the outdoor surface of the outer shoji 5A, 6A is the same in each shoji 5-7, it is arranged on the outdoor side of the outer shoji 5A, 6A. The common screen door 33 can be used, and the cost can be further reduced. Further, in each shoji 5-7, the dimension L3 from the door roller 32 to the indoor surface of the outer shoji 5A, 6A, and each rail 16
Since the dimension L7 between 18 and 18 is the same, the contact pressure between the heat insulating cover 204 and the fin 204A can be made constant, and reliable sealing performance can be secured. In addition, with each shoji 5-7, the outer calling frame 57, 67 and the inner calling frame 58,
Since the dimensions L4 and L5 up to the smoke return portion of 68 are the same, the external shoji 5A, 6A and the internal shoji 5B, 6B
You can also freely combine and.

9) Since the prospective dimensions of the window frames 1 and 2 are shared by the dimension L1, the structure (containment) on the frame side to which the sash window is attached, for example, the attachment structure for the finishing material inside the sash window, and the outer wall material. Which window frame 1, etc.
2 and shoji 5, 6, and 7 can be used in common. Therefore, in any combination of sash windows, design and construction can be simplified, workability can be improved, and cost can be reduced.

10) Even if the types of sash windows installed on the south and north surfaces of a building are different according to the required heat insulation performance, etc., the installation structure and design can be made common, and workability is improved. 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 the optimum sash window for each part such as the south surface and the north surface having different environments.

11) In the heat-insulating window frame 1, since the four heat-insulating members 11C to 13C that are continuous are provided at positions closer to the indoor side than the rails 16 to 19, that is, along the indoor sides of the inner shoji 5B and 6B, each rail is provided. 16 to 19 are outdoor members 11A, 1
Even when the rails 16 to 19 provided in 2A are exposed to the outside air and cooled, the temperature can be prevented from being transmitted to the indoor members 11B and 12B, and the heat insulation performance can be improved. Therefore, in the heat-insulating window frame 1, generation of dew condensation can be suppressed as compared with the general window frame, and a more comfortable living space can be formed.

12) In the aluminum resin composite shoji 6, since the hollow portions are formed in the heat insulating indoor members 61B to 68B, the heat insulating performance can be further improved. Similarly, since the hollow member is formed in each of the indoor members 51B, 53B, and 58B of the upper frame 51, the lower frame 53, and the inner assembling frame 58 of the heat insulating profile shoji 5, the heat insulating performance should be further improved. You can

The present invention is not limited to the above embodiment. The heat insulating window frames 1 and 2 are not limited to those in the above-described embodiment, and the configurations may be set appropriately. For example, as a heat insulating window frame, an outdoor member made of a non-ferrous metal such as aluminum and an indoor member are separately molded, and one or more plate-shaped heat insulating members made of a synthetic resin are arranged between the members, and these are caulked. You may use the insulated window frame connected.

Further, the upper frame and the vertical frame of the window frame are not limited to those of the heat insulating window frames 1 and 2 described above. For example, a non-ferrous metal outdoor member such as aluminum and a wooden room which is a heat insulating member. A heat insulating window frame formed by joining members and a heat insulating window frame formed by joining an outdoor member made of non-ferrous metal such as aluminum and an indoor member made of synthetic resin such as polyvinyl chloride resin are used. May be.

Further, only one type of heat insulating window frame may be provided, or three or more types of heat insulating window frames may be provided including the above-mentioned window frames. In short, in the present invention, the heat insulation window frame is
It suffices that at least the lower frame 12 has an indoor / outdoor member made of non-ferrous metal and a heat insulating member (a synthetic resin such as urethane) connecting these members, and is configured not to transmit the temperature of the outdoor member to the indoor side. The specific configuration may be set appropriately in the implementation.

When the heat insulating window frame is used for the sliding window, the dimensions L3 to L5 and L7 may be made common. Thereby, the shoji 5-7 can be attached to any of the window frames 1 and 2. Further, if the estimated dimensions of the window frames 1 and 2 are made common to the dimension L1, the attachment structure can be made common when the window frames 1 and 2 are attached to the frame, and the workability can be improved. Also, the dimension L2
Can be shared, the screen door 33 can also be shared.

Further, the heat insulating shoji is not limited to that of the above-mentioned embodiment, but for example, an outdoor member made of a non-ferrous metal and an indoor member are separately molded, and a plate-shaped heat insulating member made of a synthetic resin is provided between the members. You may use the heat insulation shoji which arrange | positions more than one sheet and crimps and connects. Moreover, you may use the heat insulation multi-layered shoji constituted by joining the outdoor member made of non-ferrous metal and the indoor member made of wood. Further, a heat insulating shoji in which the frame member is composed only of a heat insulating member such as synthetic resin may be used.

In short, the heat insulating shoji has at least a part having a heat insulating property (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 be configured in.

Further, although the sash window used as the sliding window has been described in the above embodiment, the present invention is
It can be applied to various sash windows having window frames and sliding doors such as a sliding window other than a sliding window, an opening window, a sliding window, a vertical sliding window, a raising / lowering window, an inside opening window, an outside opening window and the like.

For example, as shown in FIG. 9, in order to form a vertically extending window, (A1) upper frame 311 and lower frame 312 are made of non-ferrous metal indoor members 311A, 31 as window frames.
2A and the outdoor members 311B and 312B, and the heat insulating window frame 301 composed of the heat insulating members 311C and 312C connecting the indoor and outdoor members, the (B1) upper frame 341 and the vertical frame are formed of non-ferrous metal, and the lower frame 312 is formed. A heat insulating window frame 30 including a non-ferrous metal indoor member 312A and an outdoor member 312B, and a heat insulating member 312C connecting the indoor and outdoor members.
2 kinds of 2 are prepared, and as a shoji (a1) each frame 351 is made of non-ferrous metal indoor member 351A and outdoor member 351B.
And a heat insulating shovel 305 configured by a heat insulating member 351C connecting the indoor and outdoor members, (b1) each heat insulating shoji 306 including each frame 361 by an outdoor member 361A made of a non-ferrous metal and an indoor member 361B made of a heat insulating member, (C1) 3 of the general shoji 307 in which each of the frames 371 is made of non-ferrous metal
Prepare a type, and one of these window frames 301, 302,
One of the shoji screens 305, 306, and 307 may be combined to form a vertical lightning window.

At this time, the window frames 301 and 302 are formed with abutting portions against which the outdoor and indoor sides of the shoji 305 to 307 are brought into contact.
0,331 is attached. Also, each shoji 305
To 307, the airtight materials 33 of the window frames 301 and 302 are provided.
There are provided abutted portions 335 and 336 on the outdoor side and the indoor side, which abut on 0 and 331, respectively. Each of these airtight materials 3
The dimension L8 between 30 and 331 (between each abutting portion) is equal to each window frame 3
01 and 302 are the same and each shoji 3
Dimension L9 between the contacted portions 335 and 336 of 05 to 307
Are the same.

Even in such a vertical sliding window, (A
1) Thermal insulation window frame 301+ (a1) Thermal insulation screen 305, (A
1) Thermal insulation window frame 301+ (b1) Thermal insulation screen 306, (A

1) It is possible to construct a vertical sliding window of six types of combinations of the heat insulating window frame 302+ (c1) general shoji 307.
And since these 6 types of vertical sliding windows have slightly different heat insulation performance, internal design, price, etc., they are the optimum sash windows that meet the building location area, environment, window installation position, client's request, etc. Can be set.

The same setting can be made for a pull-out window, an opening window, a side-opening window, a raising / lowering window, an inside opening window, an outside opening window, etc. other than the vertical opening window. Here, when constructing a heat insulating window frame in each of these windows, the heat insulating member may be semi-externally mounted and may be provided on the indoor side with respect to the mounting piece to the body. If the heat insulating member is provided on the indoor side of the frame mounting piece in this way, the heat conduction from the outdoor surface of the window frame can be reliably blocked by the heat insulating member, and the temperature decrease on the indoor surface of the window frame can be suppressed. , The dewproof performance can be improved. On the other hand, as in the above-mentioned embodiment, when the sliding doors such as sliding windows are provided inside and outside, the heat insulating member of the window frame is located along the indoor side of the sliding doors regardless of whether it is semi-externally attached or externally attached. Should be provided.

Further, various window frames and shoji screens should be set in common according to the type of window so that they can be freely combined when constructing various windows, for example, window frames for sliding windows. The size of the rail core is the same as the size of the door roller of each shoji, and the other windows may have the same expected width, for example.

Further, the parts other than the heat insulating member of each window frame and shoji may be made of non-ferrous metal such as aluminum or stainless steel, and the specific material may be appropriately selected according to the environment around the building to be installed. Good.

Further, the present invention, like the above embodiment,
(A), (B) two types of window frames 1 and 2, (a),
Not limited to the three types of shoji 5 to 7 of (b) and (c), for example, one type of (B) window frame 2 and two types of shoji 5 of (a) and (b). 6 may be prepared and the window frame 2 and the shoji 5 and 7 may be appropriately combined to form a sash window.

Further, (c) a non-ferrous metal shoji (c1) shoji in which each of the frames is made of non-ferrous metal, or (c2) each of the frames is made of non-ferrous metal, and each of the frames has a surface. You may provide a shoji with a hole for heat insulation formed in the connection wall which connects between the exterior of a room arranged indoors. In the shoji screen of (c2), since holes are formed in the connecting wall, heat transfer from the outdoor member to the indoor member can be reduced,
The heat insulation performance can be improved as compared with the shoji of (c1). Therefore, by preparing such a shoji (c2) as well, it is possible to increase the options due to the difference in heat insulation performance, and it is possible to more easily respond to the request of the owner.

In addition to the various types of shoji (a) to (c), or in place of any of the various types of shoji, (d) an adiabatic shoji in which each frame is formed of a heat insulating member may be provided. . That is, four types of shoji (a) to (d) are prepared, (a), (b), (d) or (a), (c),
Prepare 3 kinds of shoji such as (d), or prepare and select 2 kinds of shoji such as (a) and (d), (b) and (d), (c) and (d) You may
By preparing this (d) heat insulating shoji, it is possible to further increase the choices due to the difference in heat insulating performance, and it is possible to more easily cope with the region where the heat insulating performance is particularly demanding.

In short, according to the present invention, at least two kinds of shoji screens and one or more kinds of window frames are prepared, and the heat insulation performance and design of the sash window are made different by appropriately combining these shoji screens and window frames. It suffices if it is configured to be able to.

Further, in the aluminum-resin composite shoji 6, the interior members 61B to 68B are formed with hollow portions to improve the heat insulating performance, but the shapes of the interior members 61B to 68B may be set appropriately. Moreover, in the indoor members 61B to 68B,
Although there is a part where the hollow part cannot be formed due to the limitation of the estimated size, etc., a part of the outdoor members 61A to 68A contacting the part where the hollow part is not formed is cut out to contact the heat insulating indoor members 61B to 68B. The heat transfer from the non-ferrous metal outdoor members 61A to 68A may be suppressed by reducing the area.

Further, each of the screens 5-7, 305-307
Although the multi-layered glass 29 is arranged in the above, a single plate glass may be arranged, and these may be set in consideration of the heat insulating performance and the like. At this time, various types of sash windows whose heat insulation performance is set more finely can be configured by setting a type using double glazing and a type using single glass for each shoji 5-7. . However, since the insulating efficiency of single glass is lower than that of double glass, double glass is used for the heat insulating shoji 5,6,305,306, and double glass and single glass are used only for shoji 7,307. You may set the type.
