DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window reform, and more particularly to a mounting structure for replacing an existing aluminum sash with a resin sash.

[0002]

2. Description of the Related Art Aluminum sashes have conventionally been used for windows of houses. Recently, resin sashes (hereinafter referred to as resin sashes) have been used to enhance heat insulation and prevent dew condensation. . General aluminum sash has a heat transfer coefficient of 6-7Kc
al / m2 · h · ° C, whereas the resin sash is about 2.
0 to 2.4 Kcal / m2 · h · ° C or lower,
The cooling and heating efficiency of the room can be significantly improved.

As a method of attaching a resin sash, the invention described in Japanese Patent Application Laid-Open No. 10-088907 is conventionally known. This is a technology for attaching a resin sash to a newly built house. An aluminum frame is fixed to the lower part of the window (window sill, sill), and the lower edge of the resin sash is overlapped on this aluminum frame and the two are joined together. Fix it. As a result, the lower end of the resin sash is firmly connected to the vehicle body via the aluminum frame, thereby increasing the strength of the lower frame portion.

FIG. 7 shows the principle of the mounting structure according to Japanese Patent Application Laid-Open No. 10-088907, wherein 1 is a window opening, 2 is a window base, 3 is an aluminum frame, 4 is a resin sash, and 5 is a lower end of the resin sash. It is a resin frame provided in. The weight of the resin sash including the glass 6, 7 is supported below by the aluminum frame 3,
Increases mounting strength. In Japanese Patent Application Laid-Open No. 10-088907, a mounting structure of the resin frame 5 and the aluminum frame 3 is specifically illustrated in order to prevent dew condensation on the lower frame.

[0005]

By the way, even in a house already provided with an aluminum sash window, there are many requests to replace it with a resin sash window in order to increase the heat insulation efficiency. Particularly, in a cold region, the difference in the heat transmission rate causes a significant difference in the amount of kerosene used in winter.

When renovating a house with an aluminum sash window, there are two methods for attaching a resin sash. One is to remove the entire aluminum sash and assemble a new resin sash, and the other is to attach the resin sash to the opening while leaving the aluminum sash frame material.

The method of removing the entire aluminum sash is excellent in that the resin sash can be easily assembled.
There are many problems. This is because, when removing the aluminum sash, it is necessary to break a part of the outer wall (the periphery of the window opening) and repair the outer wall after construction. Although no special skills are required, the owner dislikes damaging the outer wall, and the construction efficiency is poor. After repair, the outer wall is likely to crack and impair the aesthetic appearance.

On the other hand, when the resin sash is attached while leaving the aluminum sash frame material, the appearance is good immediately after the construction, but various problems occur thereafter.

FIG. 8 exemplifies a mounting state of an outer frame 11 of an aluminum sash and a resin sash 12. The outer peripheral frame 11 of the aluminum sash is fixed to the wooden frame 13 of the window opening, and the strength of this portion is high. In contrast, resin sash 1
2 is fixed to the wooden frame 13 with a screw 15 via a spacer 14 at the innermost part. For the moment, the resin sash 12 is also directly fixed to the vehicle body, and has a structure in which the weight is left to the vehicle body. 1
Reference numeral 6 denotes an aluminum decorative frame for concealing a gap S generated between the outer peripheral frame 11 of the aluminum sash and the resin sash 12. The gap between the front portion of the resin sash 12 and the decorative frame 16 is filled with a caulking material 17.

The reason for mounting the resin sash 12 in such a structure is that a commercially available resin sash mass-produced is designed on the assumption that the resin sash is mounted in a newly opened window opening. For example, as shown in FIG. This is because a fin 8 for mounting is provided. The mounting fins 8 have a function of ensuring the fixation when they are mounted on a newly built house, but they become a hindrance when reforming. In the case of reforming while leaving the outer peripheral frame 11 of the aluminum sash, the mounting fin 8 is left or cut off and used. In the example shown in FIG. 8, the mounting fins 8 are cut off, and as a result, a large gap S is formed between the outer peripheral frame 11 of the aluminum sash and the resin sash 12.

The first problem in the case where the outer peripheral frame 11 is left is that the support point of the resin sash 12 is only fixed by the screw 15 at the innermost part of the window opening, and the total weight including the glass 6, 7 is balanced. The bad support point (15) causes the resin sash 12 to tilt forward with the passage of time, causing distortion. The caulking material 17 also plays a role of supporting the load at the initial stage, but loses its function due to generation of a gap due to distortion and deterioration with time.

The second problem is that the outer frame 11 of the aluminum sash is used.
Despite the relatively large gap S generated between the resin and the resin sash 12, the surface is merely covered with the decorative frame 16, so that the latest resin provided with the double-glazing (6, 7) having high heat insulating properties is provided. Even if the sash 12 is used, doubts remain in the heat insulating effect. The conventional decorative frame 16 is made of aluminum and has poor heat insulation. Therefore, even if the latest resin sash 12 is attached, the heat insulating property often does not change significantly.

It is considered that this is because, due to the correlation between the deformation of the resin sash 12 over time and the caulking material 17, cool air / warm air flows through the gap S.

Therefore, an object of the present invention is to provide a method of attaching a resin sash while leaving an outer peripheral frame of an aluminum sash,
An object of the present invention is to surely prevent the resin sash from being deformed with time and to improve the heat insulating property of a gap formed between the outer frame of the aluminum sash and the resin sash.

[0015]

In order to achieve the above object, a resin sash reform mounting structure according to the present invention comprises:
A frame is provided to connect and fix the aluminum sash while interposing it in the gap between the frame material and the resin sash.
The inner peripheral portion has a contact surface that can be in close contact with the outer peripheral surface of the resin sash, and the outer peripheral portion has a contact surface that can be in close contact with a member of the aluminum sash frame material that is substantially parallel to the exterior wall surface of the house. Screws are arranged from the outside to the inside of the surface, and the frame is fixed to both the outer peripheral surface of the resin sash and the frame material of the aluminum sash.

The outer peripheral portion of the frame is formed to have a substantially concave cross section, and vertical walls are respectively provided on the inner peripheral side and the outer peripheral side of the general surface for disposing screws, and both ends are fixed to the vertical wall portion. May be provided.

A resin cover having a substantially L-shaped cross section is provided on an outer peripheral portion of the frame. The resin cover has a panel-shaped first wall portion having a length extending from the outer peripheral end to the outer wall of the frame. A second wall portion bent substantially perpendicularly from the wall portion and brought into contact with the outer wall, the first wall portion and the frame are fixed with screws, and the second wall portion and the outer wall may be fixed with screws. .

[0018]

According to a first aspect of the present invention, there is provided a frame (frame material) for filling a gap in an outer peripheral portion of a resin sash, and the frame is used to support the front of the resin sash, thereby preventing dew condensation due to the gap.

According to a second aspect of the present invention, a cover is provided on the surface of the frame to prevent the screws from being exposed, thereby improving the appearance quality.

According to a third aspect of the present invention, a resin cover is provided on the outer peripheral portion of the frame to close a gap formed between the frame and the outer frame material of the aluminum sash, thereby reliably preventing dew condensation from occurring. Aluminum outer frame material tends to cause condensation on the surface, but by covering the frame and outer wall with a resin cover, the temperature of the outside air is secondarily transmitted to the aluminum outer frame material, the temperature difference is reduced, and the aluminum outer frame material Dew condensation that occurs can be reliably reduced. In addition, this makes it possible to protect the outer wall from the dew condensation damage.

Next, the frame 41 is fitted and fixed to the resin sash 31 and the outer frame member 21 (exposed surface 29). In order to satisfy conditions such as workability, airtightness, rigidity, and aesthetic appearance, The frame 41 according to the embodiment is specifically configured as follows.

As shown in FIG. 5, the picture frame 41 is composed of a picture frame main body 42 and a decorative lid 52 covering the surface of the picture frame main body 42. Further, a resin cover 85 is provided on the outer peripheral portion of the frame 41.
Is provided.

The frame body 42 has a substantially L-shaped cross section (or T-shaped section).
(Shape). An abutting surface 47 is provided on the inner side of the window opening so as to be in close contact with the outer peripheral surface of the resin sash 31, and an exposed surface of the outer frame member 21 of the aluminum sash (a surface member substantially parallel to the wall surface outside the house) 29 is provided on the outer side. Is provided with a contact surface 48 that can abut the surface.

The contact surface 47 is bent substantially perpendicularly to the back from the contact surface 48, and a thin resin panel 43 is provided with a reinforcing portion 44 having a substantially rectangular cross section. The reinforcing portion 44 has a hollow inside in this embodiment. This is because the joints at the four corners of the frame main body 42 can be used as screw holes. In addition, the heat insulating effect is enhanced by forming the hollow portion. Further, in this embodiment, two reinforcing portions 44 are provided at the front and back of the resin panel 43 to enhance the adhesion and airtightness between the resin panel 43 and the resin sash 31. Reference numeral 84 denotes a hollow reinforcing portion having a rectangular cross section disposed on the contact surface 48.

Reference numeral 45 denotes a rubber packing for maintaining airtightness after the frame main body 42 is fitted. This rubber packing 45
Is fixed to the frame body 42 in advance, preferably hollow inside, so that it can be deformed flexibly when fitted.
FIG. 6 is an enlarged view illustrating an attached state of the rubber packing 45, in which a first locking piece 61 protruding from the reinforcing portion 44,
It is sandwiched and fixed by a substantially L-shaped second locking piece 63 raised from the resin panel 43. Reference numeral 64 denotes a thick inner peripheral fitting portion for preventing the inner portion of the rubber packing 45 from being detached by the locking pieces 61 and 63, and 65 denotes a resin sash 3.
The packing body (hollow) 66 that contacts the first member 1 is a thin connecting portion that connects the inner peripheral fitting portion 64 and the packing body 65. Of course, the rubber packing 45 may be fixed by an adhesive, but the deterioration of the adhesive due to cold and warm is assumed.
It is preferable to adopt a structure in which it is sandwiched and fixed by the locking pieces 61 and 63.

Reference numeral 71 denotes a screw driven toward the resin sash 31. Further, screws 72 and 73 are driven into the exposed surface 29 of the outer frame member 21. Screw 71 is originally frame 4
Although it is desirable to drive the resin sash 31 from the vertical surface from the contact surface 47 of the first frame, such a construction is impossible with the structure of the substantially L-shaped frame 41. Therefore, in the present invention, an inclined surface 75 of about 45 degrees with respect to the outer peripheral surface of the resin sash 31 is provided in a portion on the near side (constructor side; outside of the outer wall) of the contact surface 47. The screw 71 is driven in from outside. If the angle of the inclined surface 75 is an angle of 30 to 60 degrees with respect to the outer peripheral surface of the resin sash, it is practically usable.

The resin cover 85 is disposed outside the contact surface 48. Reference numeral 86 denotes a panel-shaped first wall having a length reaching the outer wall W from the outer peripheral end of the frame 41, and 87 is bent substantially perpendicularly from the first wall 86 to abut the outer wall W. The second wall. Also, 91 is the first wall 86 and the frame 41
Is a screw for fixing the second wall portion 87 and the outer wall W. In addition, as shown in FIG. 4, the part of the screw 92 which becomes a terminal performs a caulking process (indicated by a symbol K).

According to this structure, the front of the resin sash 31 is securely fixed to the frame 41. Further, the frame 41 is fixed to the existing aluminum sash outer frame material 21 via screws 72 and 73 at the contact surface 48. Screws 72 and 73 have different parts to be driven depending on the shape of the existing aluminum sash outer frame 21. Further, the length of the screw leg may be appropriately changed. In any case, the existing aluminum sash outer frame member 21 has a member parallel to the outer wall, and the screws 72 and 73 separate the frame 41 from the frame 41 with a leg dimension reaching a position where the driving surface including the exposed surface 19 can be driven. It is fixed to the frame member 21.

As described above, the resin sash 31 is divided into the resin sash 31 and the aluminum outer frame material 2 by the frame 41.
1 is filled with airtightness, the back is supported by a wooden screw 34, and at the same time, the front side is supported by a frame 41 by a screw 71. The frame 41 is an aluminum firmly fixed to the vehicle body. It is fixed to the outer frame member 21 of the sash.

As a result, even in the case of using a heavy sash shoji such as a high-performance double glazing, the resin sash 31 is supported by the vehicle body while dispersing the load between the back and the front.
Prevents secular deformation after renovation work. The frame 41 fills the gap between the resin sash 31 and the outer frame member 21 with high airtightness. Since the securely supported resin sash 31 is unlikely to be deformed, there is no gap for a long time at the contact portion between the rubber sash 31 and the resin sash 31 by the rubber packing 45 and the reinforcing portion 44, and the insulation efficiency is reduced, dew condensation occurs, and Problems such as entry can be more reliably prevented. In order to support the weight of the resin sash 31, the inheritance lid 52 for decorating the surface of the frame 41 is not always necessary.

The outer periphery of the frame 41 is covered with a resin cover 85.
Covered by For this reason, the space indicated by reference numeral Q in FIG. 4, that is, the outer wall W, the frame 41, and the aluminum outer frame material 2
1 can be covered from the outside, and the outside air and space Q
Can be reduced, and the condensation of the aluminum outer frame material 21 can be prevented to the maximum.

As a result of disposing the resin cover 85 in addition to the support structure for the resin sash 31, damage to the dew condensation on the outer wall can be suppressed, and ideal quality assurance can be achieved for the reformed structure.

[0035]

As described above, according to the mounting structure of the resin sash according to the present invention, the resin sash is prevented from being deformed with time while leaving the outer peripheral frame of the existing aluminum sash, and the outer peripheral frame of the aluminum sash is prevented from being deformed. The heat insulating property of the gap generated between the resin sash and the sash can be enhanced.
