Abstract

PROBLEM TO BE SOLVED: To reduce the quantities of warpage and deformation due to temperature difference between indoor and outdoor sides. SOLUTION: A stile 26 as the heat-insulating shape has an outdoor member 26A, an indoor member 26B and at least two heat-insulating connecting sections 41, 42 connecting the indoor and outdoor members 26A, 26B. One heat-insulating connecting section 42 is constituted by forming holes 47 for insulating heat to a connecting wall 46 coupling the indoor and outdoor members 26A, 26B. Even when temperature difference on the indoor and outdoor sides of the stile 26 is increased, temperature difference between the outdoor member 26A and the indoor member 26B can be reduced because heat is transferred minimally through the bridge section 48 of the connecting wall 46 between the outdoor member 26A and the indoor member 26B, and the quantities of the warpage and deformation of the stile 26 can also be lowered.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat-insulating profile and a heat-insulating shoji, and can be used for various sash windows such as a sliding window and a sliding window.

[0002]

BACKGROUND ART As a sash window constituting a window of a building, there is a heat insulating sash in which a heat insulating material is interposed in addition to a normal sash. Insulation sash screens are usually made of a heat-insulated profile consisting of an outdoor member and an indoor member made of metal such as aluminum, and a heat-insulating material made of synthetic resin that connects the indoor and outdoor members. Heat transfer was reduced to increase the heat insulation performance.

[0003]

By the way, in a shoji using such a heat-insulated profile, particularly in a vertical frame on the door-end side, for example, the outdoor member of the frame is heated by the direct sunlight of the sun and the indoor member is heated. When the temperature difference between the indoor member and the outdoor member increases, or when the temperature of the outside air decreases in winter and the temperature difference between the indoor and outdoor members increases and the temperature difference between the outdoor member and the indoor member increases, the thermal expansion between the indoor member and the outdoor member increases. Therefore, there is a possibility that the vertical frame warps so as to be convex toward the outside or the inside of the room. Such a problem is not limited to the insulated profile used for the shoji of windows arranged on the outer wall of the building, for example, doors and windows that partition a bathroom or a sauna room from other spaces, and even in factories and the like. Insulated shapes used for doors and windows that separate the space maintained at a high temperature or the space maintained at a low temperature such as a freezer from other spaces, such as doors and windows, where the temperature difference between the indoor and outdoor areas is large. Could also occur.

[0004] It is an object of the present invention to provide a heat-insulated profile and a heat-insulating shoji that can reduce the amount of warpage due to a temperature difference between the inside and outside of a room.

[0005]

The heat-insulated profile of the present invention comprises an indoor member and an outdoor member, and at least two heat-insulating connectors for connecting the indoor and outdoor members. One of the heat insulating connecting portions is formed by forming a heat insulating hole in a connecting wall connecting the indoor and outdoor members.

In such a heat-insulated profile of the present invention, at least one of the two heat-insulating connecting portions connecting the indoor and outdoor members is connected to the indoor and outdoor members by a connecting wall formed with a heat insulating hole. With the configuration, when the temperature difference between the indoor and the outdoor becomes large, the minimum heat transfer is performed between the indoor member and the outdoor member via the connection wall, so that the temperature difference between the indoor and the outdoor member is reduced. It is possible to reduce the amount of warpage of the profile itself.

Further, the heat transfer at the connecting wall can be adjusted by the size of the hole formed in the connecting wall, that is, the area of the connecting wall connecting the indoor and outdoor members. By adjusting the amount of heat transfer in accordance with the conditions such as the climate of the area where the device is installed, the balance between the heat insulation performance and the amount of warpage can be appropriately set.

Further, since the indoor and outdoor members are connected by the two heat-insulating connecting portions, the connecting strength can be improved as compared with the case where only one connecting portion is provided, and a heat insulating hole is formed in the connecting wall. Even in such a case, sufficient strength can be obtained.

Here, it is preferable that a heat insulating film for covering the holes is attached to the connecting wall in which the holes for heat insulation are formed. If the hole in the connecting wall is closed with the heat insulating film, air does not flow through the hole, and rainwater or the like does not enter, so that airtightness and waterproofness can be easily secured.

[0010] The other heat-insulating connecting portion of the two heat-insulating connecting portions may be formed of a heat insulating material for connecting indoor and outdoor members. Both of the two heat-insulating connection portions may be formed by the connection wall in which the heat insulating hole is formed, but one heat-insulating connection portion is formed by the connection wall in which the heat insulating hole is formed, and the other is formed by the other. If the heat-insulating connection part is formed of a heat insulating material, the airtightness and the connection strength can be further improved.

Further, a heat-insulating coating layer may be provided on the indoor surface of the indoor member of the heat-insulated profile.
If a heat-insulating coating layer is provided on the indoor surface of the indoor member, the heat-insulating performance and dew-proofing performance of the heat-insulated profile can be further improved.

The heat insulating shoji of the present invention is a heat insulating shoji in which an upper frame, a lower frame and left and right vertical frames are framed and a face material is incorporated, and at least a vertical portion of the left and right vertical frames on the door end side. The frame is made of the heat-insulated shape. Here, the upper frame, the lower frame, the combination frame (vertical frame), etc. other than the vertical frame on the door-end side may be constituted by the above-mentioned heat-insulated members, or the conventional indoor and outdoor members are connected by the heat-insulating material. You may comprise using a heat insulation shape material.

[0013] The heat insulating shoji has a larger length dimension than the upper and lower frames, has a simpler structure than the mating frame, and the indoor and outdoor members are completely partitioned into the indoor side and the outdoor side of the heat insulating material. The amount of warpage deformation in the vertical frame on the door side arranged is the largest. For this reason, by using a heat-insulated profile having a small amount of warpage deformation due to the indoor / outdoor temperature difference, the amount of warpage deformation in the heat insulating sash can be effectively reduced.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. 1 to 3 show an embodiment in which the present invention is applied to a semi-external type sliding window 1. FIG. 1 shows an inside view of the sliding window 1, and FIG. II-
A cross-sectional view along line II is shown.

The sliding window 1 has a window frame 2, an outer sash 3 and an inner sash 4. The window frame 2 is formed by joining an upper frame 11, a lower frame 12, and left and right vertical frames 13 in a square frame shape. As shown in FIG. 2, each of the frames 11 to 13 is made of a non-ferrous metal aluminum outdoor member 13A, an aluminum indoor member 13B, and these indoor and outdoor members 13A, 13B.
And a heat insulating material 13C made of a resin such as a urethane resin or a vinyl chloride resin.

In the window frame 2, there are provided a sash 3 which is arranged outside the room and is guided by the outer rails 16 and an sash 4 which is arranged inside the room and is guided by the inner rails 17. ing.

Each of these shojis 3, 4 is provided with upper frames 21, 22.
, Lower frames 23, 24, and left and right doorside vertical frames 25, 26
, And the outer mating frame 27 and the inner mating frame 28 are framed respectively. A double-layer glass 29 is fitted to the inner peripheral surfaces of the frames 21 to 28 via a gasket 30.

Each of the frames 21 to 24, 27, and 28 has an aluminum outdoor member 27A, 28A, an aluminum indoor member 27B, 28B, and an outdoor member 27A, 28B.
A and heat insulating materials 27C and 28C made of urethane resin or vinyl chloride resin for connecting the indoor members 27B and 28B.

On the other hand, as shown in FIG. 3, the door-side vertical rails 25 and 26 have aluminum outdoor members 25A and 26A, aluminum indoor members 25B and 26B, and these outdoor members 25A and 26A. And two heat-insulating connecting portions 41 and 42 connecting the indoor members 25B and 26B.

Of the two heat-insulating connecting portions 41, 42, the connecting portion 41 on the door-end side (outer peripheral side) is connected to the other frames 21 to 24, 27.
And 28C, a heat insulating material 45 made of the same urethane resin or vinyl chloride resin as the heat insulating materials 27C and 28C.

On the other hand, the connecting portion 42 on the inner peripheral side is
5A, 26A and the indoor members 25B, 26B, and are formed of an aluminum connecting wall 46 integrally formed integrally therewith.

The connecting wall 46 is formed with a heat insulating hole 47 punched out by press working or the like, and a bridge portion 48 left between the holes 47 or the like. It has been adjusted to be a value. That is, the heat transfer coefficient of the connecting wall 46 is appropriately set by the size, the interval (the dimension of the bridge portion 48) and the number of the holes 47 of the connecting wall 46, whereby the heat transfer coefficient can be positively adjusted. For example, in this embodiment, the width of each of the shojis 3 and 4 is about 1700 mm, the height is about 2200 mm, and the length of the holes 47 along the longitudinal direction (vertical direction) of the vertical frames 25 and 26 is 300 mm. And the distance between the holes 47 is 1
It is set to 0 mm. The hole 47 is provided in the vertical frames 25, 2
Reference numeral 6 is formed in an intermediate portion excluding upper and lower ends connected to the upper and lower frames 21 to 24.

To manufacture the door-side vertical stiles 25, 26 in this embodiment, the outdoor members 25A, 26A and the indoor members 25B, 26B and the connecting wall 46 are integrally formed by extrusion of aluminum. In addition, the heat-insulating connecting portion 41
The parts are the outdoor members 25A, 26A and the indoor member 25.
The projection urging portion 49A and the cutting portion 49B integrally formed with B and 26B form a concave urethane injection pocket 49 into which the heat insulating material 45 is injected.

The cut portion 49B of the urethane injection pocket 49 of each of the integrally formed frames 25 and 26 is cut and separated by a cutter or the like, and a heat insulating sheet is wrapped around the cut portion. A heat insulating material 45 such as a resin is injected and cured. Then, after the heat insulating material 45 is cured, a hole 47 is formed in the connecting wall 46 by press working or the like. As described above, the door stiles 25 and 26 are manufactured.

Then, the other frames 21 to 24, 27 to 28 and the vertical frames 25, 26 are joined to form a frame, and the multi-layer glass 29 is formed.
To produce the heat insulating sashes 3 and 4, and the sliding sashes 3 and 4 are arranged in the window frame 2 to form the sliding window 1.

In the vertical frames 25 and 26 of the shoji screens 3 and 4, the temperature difference between the indoor and outdoor areas increases, and the outdoor members 25A and 2
6A and the indoor members 25B and 26B, a minimum heat transfer is performed via the bridge portion 48 of the connecting wall 46, and the temperature difference between the outdoor members 25A and 26A and the indoor members 25B and 26B. And the amount of warpage deformation is reduced. The heat transfer coefficient via the connecting wall 46 is set by the area of the bridge portion 48, that is, the size and interval of the hole 47.

According to the present embodiment, in the door-side vertical stiles 25 and 26, of the two heat insulating connecting portions 41 and 42 connecting the outdoor members 25A and 26A and the indoor members 25B and 26B, Since the connecting portion 42 on the peripheral side is formed by the connecting wall 46 having the bridge portion 48 that is integrally formed continuously with the indoor and outdoor members 25A, 26A, 25B, and 26B and performs a minimum heat transfer, the indoor side is formed. Outer members 25A, 26
Heat can be transmitted between the indoor and outdoor members 25A to 26B, as compared with the case where A, 25B, and 26B are connected only by the heat insulating material 45. Therefore, even when the temperature difference between the indoor and outdoor of the shoji screens 3 and 4 becomes large, the indoor and outdoor members 25A, 26A, 25B, 2
Since the temperature difference between 6B and the difference in thermal expansion can be reduced, the amount of warp deformation in the vertical frames 25 and 26 can be reduced.

Therefore, it is possible to suppress the amount of warpage of the door-side vertical stiles 25 and 26 where the amount of warpage of the shojis 3 and 4 becomes the largest, and also to reduce the amount of warp of the entire shojis 3 and 4.

The amount of heat transfer in the connecting wall 46 can be adjusted by the size and interval of the holes 47 (dimensions of the bridge portion 48). For this reason, the amount of heat transfer can be adjusted according to the climatic climate and the like in the area where the sliding window 1 is installed, and the conflicting performance between the heat insulation performance and the warpage deformation can be appropriately set.

Further, the connecting walls 46 are provided on the vertical frames 25 and 26 where the amount of warp deformation of the shojis 3 and 4 is the largest, and the amount of warp deformation is reduced. Since the overall performance includes not only the frames 25 and 26 but also the other frames 21 to 28 and the glass 29, according to the present embodiment, the amount of warpage can be sufficiently reduced, while the heat insulating performance by heat transfer. Can be made very small. That is, in the experiment according to the present embodiment, the reduction of the heat transmission coefficient in the sliding window 1 using the vertical stiles 25 and 26 can be suppressed to about 1% as compared with the conventional case, but the amount of warpage deformation is large. According to the present embodiment, the heat insulation performance and the amount of warpage can be set in a well-balanced manner.

The heat-insulating connecting portions 42 of the vertical frames 25, 26
Are the outdoor members 25A and 26A, and the indoor members 25B and 26B
Since the hole 47 can be formed by pressing the connecting wall 46 integrally formed with the insulating member 45, the manufacturing time can be reduced and the production efficiency can be improved as compared with the case where the heat insulating material 45 is used. That is, when the heat-insulating connection portions 41 and 42 are formed by injecting the heat-insulating material 45 together, the other heat-insulating material 45 cannot be injected unless one of the heat-insulating materials 45 is cured. When a resin or the like is used, it takes two days or more to manufacture the vertical frames (insulated members) 25 and 26. However, in the vertical frames 25 and 26 of the present embodiment, the heat insulating material 45 is injected only for one day. Since it is a location, the manufacturing time of the vertical frames 25 and 26 can be reduced by half, and the production efficiency can be improved.

Also, since the two heat insulating connecting portions 41 and 42 are provided in the vertical frames 25 and 26, the indoor and outdoor members 25 and 26 are provided.
A, 26A, 25B, 26B can improve the connection strength between,
It is possible to form a heat-insulated profile having a higher rigidity as compared with the case where one connecting portion is provided. In particular, since the heat insulating material 45 constituting the heat insulating connecting portion 41 is provided continuously along the vertical frames 25 and 26, the connecting strength can be improved.

Further, since the connecting wall 46 in which the hole 47 is formed is provided on the inner peripheral side of the vertical frames 25 and 26, the vertical frames 25 and 26 are provided.
Even if air flows in through the openings at the upper and lower ends between the heat insulating connecting portions 41 and 42 and flows out through the holes 47, the air is blocked by the gasket 30 and the outer peripheral sides of the vertical frames 25 and 26 are formed by the heat insulating material 45. Because it is closed, the air that has flowed into the vertical frames 25 and 26 does not flow indoors or outdoors,
A decrease in heat insulation performance can be prevented. Further, since the heat-insulating connecting portion 41 is formed of the continuous heat-insulating material 45, no outside air or rainwater enters between the heat-insulating connecting portion 41 and the heat-insulating connecting portions 41 and 42. , 26, that is, the airtightness and waterproof performance of the sliding window 1 can be improved.

The present invention is not limited to the above embodiment. For example, in the above-described embodiment, the hole 4
Although 7 is formed by punching by press working, as shown in FIG. 4, a hole 47 for heat insulation may be formed by bending the connecting wall 46 toward the heat insulating material 45 without completely punching. In short, the hole 47 may be formed in the connecting wall 46 so that the bridge portions 48 for transmitting heat are provided at predetermined dimensions and at intervals, and specific implementation means may be appropriately set in implementation.

Also, as shown in FIG.
In the heat-insulating shaped members constituting the indoor and outdoor members 25A and 26,
A, two heat-insulating connecting parts 4 connecting between A, 25B and 26B
Both 1 and 42 may be configured by the connecting wall 46 including the hole 47 and the bridge portion 48. If both of the two heat insulating connecting portions 41 and 42 are formed of the connecting wall 46 in this manner, the manufacturing time can be reduced as compared with the case where the heat insulating material 45 such as urethane resin is filled, and the production efficiency can be further improved. it can.

At this time, the hole 47 of the heat insulating connecting portion 41 on the outer peripheral side is used.
Is preferably closed with a heat insulating film 50.
Further, the hole 47 of the heat insulating connection portion 42 on the inner peripheral side may be closed with the heat insulating film 50. When the hole 47 is formed in the heat insulating connection portion 41 on the outer peripheral side, outside air flowing between the heat insulating connection portions 41 and 42 from the upper and lower ends of the vertical frames 25 and 26 may enter the room through the hole 47. There is a hole 47
Is closed by the heat insulating film 50, the outside air does not flow through the holes 47 and rainwater does not enter, so that the airtightness, waterproofness, and heat insulating property can be sufficiently ensured.

As shown in FIG. 5, a heat-insulating coating layer is provided on the indoor surfaces of the indoor members 25B and 26B of the heat-insulated sections in which both of the two heat-insulating connecting portions 41 and 42 are formed by the connecting wall 46. It may be provided. This heat-insulating coating layer can be formed, for example, by coating a resin film on the indoor surfaces of the indoor members 25B and 26B, or by fitting a resin molded product. Such a heat-insulating coating layer is applied to the indoor members 25B and 26B.
If provided on the indoor surface of B, the heat insulation performance and dew-proof performance of the heat-insulated profile can be improved. The heat-insulating coating layer is not limited to the heat-insulated profile shown in FIG. 5 and may be applied to other heat-insulated profiles.

Further, as shown in FIG.
Of the two heat-insulated connecting portions 41 and 42 of the heat-insulated section, the outer-side heat-insulating connecting portion 41 is constituted by a connecting wall 46 including a hole 47 and a bridge portion 48, and the inner-side heat-insulating connecting portion 42 is formed. May be interposed with a heat insulating material 45 such as urethane resin. Also in this case, as in the case of FIG. 5, it is preferable that a heat insulating film 50 that closes the hole 47 is attached to the connecting wall 46 of the heat insulating connecting portion 41 on the outer peripheral side.

Further, the heat-insulated profile of the present invention is characterized by
7 and 8 are not limited to those used for the vertical frames 25 and 26 of FIG.
As shown in (1), it may be used for the lower frames 23, 24 of the outer sash 3 and inner sash 4. That is, as shown in FIG. 7, the lower frame 23 of the outer sliding door 3 includes an outdoor member 23A and an indoor member 23B,
The heat insulating connecting portions 61 to 63 for connecting these are provided. That is, since the lower frame 23 of the outer sash 3 has a large height, the outdoor member 23A and the indoor member 23B are connected by the three heat insulating connecting portions 61 to 63.

Of these heat-insulating connecting portions 61 to 63, for example, the connecting portion 61 on the inner peripheral side (upper side) is
7 and a connecting wall 46 having a bridge portion 48,
The other connecting portions 62 and 63 are made of a heat insulating material 4 such as urethane resin.
5 may be formed.

On the other hand, as shown in FIG. 8, the lower frame 24 of the inner shoji 4 is provided with an outdoor member 24A and an indoor member 24B, and heat insulating connecting portions 71 and 72 for connecting these members. The lower frame 24 of the inner sash 4 is smaller in height dimension than the lower frame 23, so that the outdoor member 24A and the indoor member 24B are connected by the two heat insulating connecting portions 71 and 72.

The outer (lower) connecting portion 72 of the heat insulating connecting portions 71, 72 is formed by the connecting wall 46 having the hole 47 and the bridge portion 48, and the inner connecting portion 71 is formed. May be formed by a heat insulating material 45 made of urethane resin or the like. In this case, the connecting wall 46 can be used as a mounting portion of the door stroller, whereby the door stroller can be firmly fixed.

Further, the heat-insulated profile of the present invention comprises a vertical frame 25,
26, not only those used for the lower frames 23 and 24 but also those used for the upper frames 21 and 22 and the combination frames 27 and 28. That is, the heat-insulating sash of the present invention is not limited to the use of the heat-insulated profiles only in the vertical frames 25 and 26 on the door-end side.
It is also possible to use the above-mentioned heat-insulated shape for a combination frame.

However, the upper frames 21, 22 and the lower frames 23, 24
Since the size is smaller and the amount of warpage is smaller than those of the vertical frames 25 and 26, the heat-insulated profile of the present invention may not be used. Also, as shown in FIG. 2, the inner mating frame 28 is disposed on the indoor side of the outer mating frame 27 and does not much touch the outside air, and the temperature difference between the outdoor member 28A and the indoor member 28B does not increase so much. Since the amount of warpage deformation is small, the heat-insulated profile of the present invention may not be used. Furthermore, since the exterior member 27A is formed so that the outdoor member 27A wraps around to the indoor side and has a small amount of warpage deformation, the heat-insulating profile of the present invention may not be used. In short, the heat-insulated profile of the present invention is particularly suitable for the door-side vertical frames 25 and 26 of the shoji screens 3 and 4.

The heat insulating material 45 is not limited to a material into which a urethane resin or a vinyl chloride resin is injected, but is a plate made of a synthetic resin, and is placed between the indoor and outdoor members and caulked. Thereby, these indoor and outdoor members may be connected. In short, in the heat-insulated profile of the present invention, the indoor and outdoor members are connected by two or more heat-insulating connection portions, and at least one heat-insulating connection portion has a bridge portion formed with a heat-insulating hole and transmitting heat. What is necessary is just to be comprised by the connected wall made, and what is necessary is just to set the specific structure suitably in implementation.

Further, the heat-insulated profile of the present invention is not limited to being used as a frame material for shoji screens 3 and 4, but may also be used for frame materials for window frames, doors of entrances and doors of buildings, shutters, etc. Further, the present invention may be used for a shoji or a door provided on a partition wall or the like in a building, and in particular, it can be used for various fittings having a large temperature difference between the inside and the outside and requiring heat insulating performance.
