DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window frame mounting structure in a wooden building such as a house.

[0002]

2. Description of the Related Art Conventionally, for example, window frames in houses and the like include, for example,
There is a type obtained by processing a metal such as aluminum into a predetermined shape. However, in recent years, with the diversification of houses, buildings have been required to have not only functionality and livability but also additional elements such as individuality, aesthetics, and luxury. In particular, in wooden buildings, window frames are made of wood-like materials to give a warm wooden texture and to eliminate the sense of incongruity with the surroundings of the room, and to try to enhance the texture and luxury. It has become.

[0003] Such a wood-like window frame is, for example, formed by processing or combining natural wood into a predetermined shape, or obtained by extrusion or injection molding of a resin. Printed or painted.

[0004]

However, in the case of a window frame made of natural wood, the processing requires a lot of labor, time, and advanced technology. Therefore, it cannot be processed into a complicated shape, and cannot be processed into a shape provided with an engagement piece that can be joined with the aluminum sash with one touch, for example, at a joint portion with the aluminum sash. There are circumstances. Therefore, in order to join the window frame to the aluminum sash, means such as bonding or nailing is unavoidable, which makes the mounting operation of the window frame more complicated and troublesome.

[0005] When attaching this window frame,
It is necessary to use a window frame positioning scrap as shown in FIG. The scraps 1 are arranged along the wall surface of the wall panel 2 and are temporarily fixed to the wall panel 2 by nailing or the like.
The window frame 3 is positioned by fitting into the inside. After attaching the window frame 3, the scrap 1 is removed. As described above, since the end piece for positioning the window frame is required, the types of members are increased, and the operation is complicated, which may hinder the promotion of industrialization.

In the case of a window frame formed by printing and painting on the surface of a resin, the shape of the resin is good, so that the window frame can be processed into a complicated shape, which is convenient for joining with an aluminum sash. On the other hand, on the other hand, there is a complaint that the wood pattern formed by printing or painting has no depth, and lacks the warmth and texture of natural wood.

The present invention has been made in view of the above circumstances, and can be processed into a desired shape by a simple molding method, and can be easily and simply connected to an aluminum sash and attached to an end surface of a wall panel with one touch. It is an object of the present invention to provide a window frame mounting structure capable of giving a woody appearance.

[0008]

In order to achieve the above object, the present invention relates to a method in which an adjusting member is joined to an end face of a wall panel facing an opening in which a window is to be formed, via an adjusting member, and an engaging recess or engaging member is provided on the indoor side. An aluminum sash arranged with the mating convex portion facing, and having the mating concave portion or the mating convex portion or the mating concave portion fitted to the mating convex portion and being engaged with the aluminum sash,
A window frame arranged so as to cover the room facing the room and the opening of the aluminum sash, and having a window frame joined to the adjusting member by an adhesive, wherein the window frame has an opening on the surface facing the adjusting member. An adhesive recess for accommodating an outflow of the adhesive used for joining the window frame and the adjusting material is provided, and the window frame is subjected to a grinding treatment and an inorganic pigment is carried on the surface. It is characterized in that a mixture obtained by mixing the obtained cellulose-based fine particles with a resin material is molded by extrusion or injection molding.

[0009]

According to the window frame mounting structure of the present invention, the fitting recess or the fitting projection of the aluminum sash and the fitting projection or the fitting recess of the window frame are fitted to each other to form the chamber. The window frame can be easily attached to a predetermined position by one-touch operation from the inside. Therefore, it is possible to omit the use of the scrap for positioning the window frame. In addition, since a window frame made of a mixture of cellulosic fine particles mixed with a resin material is exposed on the indoor side, a warm woody feeling similar to natural wood is given to the room. Further, since the window frame is formed by extrusion or injection molding of a mixture in which the cellulose-based fine particles are mixed with the resin material, the moldability is good and the desired shape can be easily processed. In addition, since the window frame is provided with an adhesive recess, even when the adhesive used for bonding the window frame and the adjusting agent flows out, the outflow is stored in the adhesive recess. As a result, bleeding of the adhesive onto the window frame surface, and consequent contamination of the surface are prevented.

The bar 27 comprises vertical bars 28, 28, an upper bar 29 and a lower bar 30, and if necessary, the vertical bars 28, 28
Or between the upper and lower rails 29, 30.

As shown in FIG. 1, the vertical bar 28 has a recess 31a into which the peripheral edge of the window glass 26 is inserted, and the aluminum bar main body 3 is formed by forming aluminum into a substantially rectangular frame in cross section.
1 and a beam cover 32 which is joined to a surface of the aluminum beam main body 31 facing the indoor side and the outside of the opening and covers the entire surface. Recess 31a of window main body 31 and window glass 2

At the end of the aluminum bar main body 31 facing the outside of the opening, there is provided an engagement concave portion 31b facing the inside of the room, and near the end facing the inside of the opening, the inside of the opening is provided. A rib (engagement convex portion) 31c protruding in the direction is provided to extend vertically. On the other hand, a groove (fitting recess) 32a is provided on the inner surface of the crosspiece cover 32 at a position corresponding to the rib 31c. As a result, the end (fitting convex portion) 32b of the beam cover 32 is fitted into the engaging concave portion 31b, and the rib 31c and the groove 32a are fitted together. It is configured to be able to engage.

In the window frame mounting structure described above, the window frame 18 and the crosspieces 32 of the window plates 24A and 24B are subjected to a grinding treatment and a cellulose pigment having an inorganic pigment carried on the surface thereof. It is manufactured by applying a coating material to the surface of a molding obtained by extruding or injection molding a mixture obtained by mixing the system fine powder particles with a resin material.

Hereinafter, the molding material will be described in detail.

As the resin material forming the molding material, vinyl chloride resin, phenol resin, polyethylene resin, polypropylene resin, ABS resin, polycarbonate resin,
A polyurethane resin or the like is used. Then, a cellulose-based fine particle carrying a white inorganic pigment is blended with the resin material, and a known additive is blended and mixed as necessary. Then, the mixture is extruded or injection-molded to form the molding material. Are formed.

Here, as the cellulosic fine particles carrying the white inorganic pigment, coarsely pulverized raw materials of various plant cell bodies such as coarsely pulverized wood, coarsely pulverized bacas, and coarsely pulverized rice straw are used. What was obtained by grinding is used. In order to obtain a coarsely pulverized raw material, the chips and the like are pulverized by mechanical impact crushing to obtain a coarsely pulverized powder having a particle size smaller than 150 mesh, preferably smaller than 120 mesh.
Here, for mechanical pulverization, for example, an impeller mill (IM
P-250; manufactured by Seishin Enterprise Co., Ltd.) is preferably used.

The grinding treatment of the raw material pulverized material is preferably performed by, for example, a ball mill shown in FIG. This ball mill is provided with a cooling jacket 42 on a peripheral wall of a mill body 41 which is open to the atmosphere. Cooling water is supplied from a supply pipe 43 into the cooling jacket 42 and discharged from a drain pipe 44 to circulate the cooling water. Thereby, the temperature inside the mill main body 41 is set to a preset temperature, for example, 80 ° C. or less.

Here, the motor 4 is provided above the mill body 41.
5 is provided, and at the bottom of the motor 45, a rotor 47 for stirring the ball 46 in the mill main body 41 is provided. The rotor 47 is rotated by the drive of the motor 45, and agitates the ball 46 and the material to be ground to bring them into mechanical contact. A take-out port 49 which is opened and closed by a valve 48 is provided below the conical bottom of the mill main body 41 so that the material to be ground after the grinding processing can be discharged.

As the ball 46 loaded in the mill body 41 of the ball mill, it is preferable to use ceramic balls having an outer diameter of 3 mm to 5 mm, particularly zirconia or alumina ceramic balls. The use of balls is preferably avoided. This is because, in the case of a metal ball such as stainless steel or steel, there is a risk that ground cellulose powder such as wood powder may bind to the surface of the ball, or may cause deterioration of the ground powder due to heat generated by contact between the metal balls. Because.

The dry ball mill may be of a closed type or an open-to-atmosphere type. When the closed type ball mill is employed, the mill is filled with an inert gas such as nitrogen gas. Is preferred.

In this ball mill, the balls 4 used
The surface temperature of No. 6 is set in the range of 90 ° C. to 120 ° C., and the above-mentioned crushing / grinding and drying of the raw material pulverized material are performed so that the room temperature of the mill body 41 does not exceed 80 ° C. . Here, regarding the temperature control of the ball 46 used,
Based on the capacity of the mill body 41, the amount of the balls 46 charged into the mill body 41, the material and dimensions of the balls 46, the charging temperature, the amount of the pulverized material, and the water content, the stirring speed and the mill body This is performed by adjusting the amount of cooling by the cooling jacket 42 provided around the periphery 41.

The surface temperature of the ball 46 varies depending on the target material.
The temperature is preferably in the range of 0 ° C to 120 ° C from the viewpoint of the efficiency of pulverization and grinding. However, when a long time is required for pulverization / grinding, the temperature is preferably from 90 ° C to 100 ° C from the viewpoint of preventing explosion. Further, when there is a danger of a violent explosion during the pulverization / grinding, the oxygen concentration in the mill body 41 is preferably adjusted to 15% or less. In this case, for example, nitrogen gas is continuously supplied into the ball mill. May be adopted.

According to the crushing / grinding treatment by such a ball mill, the internal temperature of the mill body 41 rises due to the frictional heat generated by the rotation of the balls 46, while the milling water is circulated through the cooling jacket 42. By adjusting the temperature in the main body 41 and the surface temperature of the ball 46 to the above-mentioned ranges, the raw material pulverized material is pulverized and dried under strong heating conditions at the same time, whereby the particle size is desired. The range is adjusted to, for example, 100 μm or less, and the water content is adjusted to 2.0% by weight or less.

According to this treatment, the ball 46 comes into contact with the crushed raw material charged in a coarse powder state, and the crushed raw material contacted with the ball 46 is ground in a broken state. Thereby, the breaking and the grinding are efficiently performed.

That is, when the crushed raw material comes into contact with the surface of the ball 46, it is mechanically crushed and abraded to be crushed and ground, and simultaneously heated and dried.
This is because the water content is efficiently removed. Also, since the fibers in the raw material pulverized material are rapidly cooled when they are separated from the ball 46, they are rapidly cooled when they are repeatedly heated and cooled.
As a result, the tips of the fibers are efficiently ground by the balls 46, and as a result, ground cellulose-based fine particles having an independent particle shape with little cilia on the peripheral surface are obtained.

Then, the cellulose-based fine powder particles thus obtained are classified, and the particle size in a desired range (for example, 1 to 5) is obtained.
10 μm, 10 to 20 μm, 20 to 50 μm, 50 to 1
00 μm) to obtain the cellulose-based fine particles of the present invention for supporting a white inorganic pigment.

The white inorganic pigment to be supported includes:
Titanium oxide, lithopone, white carbon, calcium carbonate, and the like can be used, but titanium oxide is particularly preferable for imparting sufficient whiteness to the obtained window frame 18 and crosspiece cover 32. The particle size of the white inorganic pigment is adjusted to be sufficiently smaller than the cellulosic fine powder particles.

As a method of supporting the white inorganic pigment on the cellulose-based fine particles, for example, mixing the cellulose-based fine particles with a white pigment and dispersing the obtained mixed particles in a gas phase while applying an impact force Is applied to the particles by applying mechanical and thermal energy mainly to the particles, the cellulose-based fine particles are used as the base particles, and the pigment particles are carried on the peripheral surface of the base particles.

As another method, mixed particles of cellulose-based fine particles and a white pigment are put into a ball mill as shown in FIG. A method of supporting pigment particles can also be adopted.

By performing such a supporting treatment, the white inorganic pigment particles 50 are supported in a biting state on the peripheral surface of the cellulose-based fine particles 51 as shown in FIG. Note that the amount of the white inorganic pigment to be carried is an amount that overlaps the peripheral surface of the cellulose-based fine particles serving as the base particles and covers the peripheral surface. Is appropriately determined according to the desired whiteness of the image.

The pigment-carrying cellulosic fine particles thus obtained have a color tone substantially the same as the color tone of the white inorganic pigment, and agglomeration is recognized in both the production process and the storage process of the supported fine powder particles. Can not be done.

Here, as for the compounding amount of the supported fine particles with respect to the resin material, for example, in the case of using a vinyl chloride resin, about 20 to 50 parts by weight of the supported fine particles are mixed with 100 parts by weight of the resin. In this way, a mixture obtained by mixing the resin material with the cellulose-based fine particles having been subjected to the grinding treatment and having the white inorganic pigment supported on the surface is obtained, and the mixture is formed into a desired shape by extrusion or injection molding. Thus, a molding material is obtained.

As the coating applied to the surface of the molding material, those which are used as coatings as the resin component can be almost used, and among them, urethane resin, acrylic resin, melamine resin, polyester resin and the like are preferable. Used for As a pigment, for example, a brown pigment such as iron oxide is used to give a woody appearance.

In particular, when it is desired to perform all matting, a paint containing the above-mentioned ground cellulose-based fine particles may be used. Here, when the milled cellulose-based fine particles are blended, the particle size is 1 to 1 as the cellulose-based fine particles.
It is preferable to use one of about 5 μm.

Prior to applying the coating material to the molding material, the surface of the molding material is subjected to the following treatment as a pretreatment.

First, the surface to be coated of the molding material is ground by a brush or a baffle to make the surface to be coated rough and to remove a part of the surface resin. Then, by the grinding treatment, unnecessary irregularities generated at the time of molding are smoothed and a large number of fine scratches are formed on the molded material. The main purpose of this step is to eliminate surface gloss, but in particular, if a brush with an irregular tip is used, the surface may be roughened, and color unevenness or the like may be caused by coloring by applying a paint described later. This makes it possible to further enhance the feeling of wood and further improve the penetration of paint.

Also, in this case, the pigment-carrying cellulose fine powder particles located on the surface portion by grinding the surface are peeled off of the white inorganic pigment carried thereon, and as a result, the inside of the cellulose fine powder is exposed and formed. Improve the wood texture of the lumber surface. In addition, unevenness occurs in the whiteness of the surface due to such a grinding treatment, and the paint suction and the condition of the paint are slightly different from each other when the paint is applied, which will be described later. The molded material gives a more woody feel.

Next, a decorating process by embossing is performed on the ground surface to be coated. This embossing process is to insert a resin molded product between the punch and the die to form a wood-grain-like uneven pattern, or to roll the resin molded product between embossing rolls to continuously form a wood-grain-like uneven pattern How to

Next, a paint is applied to the embossed surface to make the grain pattern clear, and excess paint on the painted surface is wiped off by a roll around which a nonwoven fabric or the like is wound. Here, as the application of the paint, a conventionally known application method such as a spraying method using a spray gun or various fluid immersion methods can be adopted.

Further, a known top coat treatment is performed on the painted surface, and the coated surface is cut into required dimensions as necessary to obtain a window 18 frame and a crosspiece cover 32 as products. The cutting for obtaining the desired dimensions may be performed before the grinding process,
Further, it goes without saying that it may be performed before embossing. Thus, the paint is applied to the surface of the molding material, and the desired window frame 18 and crosspiece cover 32 are obtained.

Next, the window frame 18 obtained as described above is used.
A method of attaching the beam cover 32 to a predetermined position of the opening 12 will be described.

Attachment of the window frame 18 is performed first by using the vertical frame 19A,
19B and the upper frame 20 are assembled in a U-shape in advance using the fixing hardware 23, and the window frame 18 is pushed into the opening 12 from the room side. At this time, the vertical frame 19
An adhesive 21 is applied to at least one of the holding pieces 19c of A and 19B or the surface of the adjusting material 15 to be in an uncured or semi-cured state. As the window frame 18 is pushed in, the holding pieces 19c of the vertical frames 19A and 19B
Springs 17i of the vertical sashes 17A and 17B and the adjusting member 15
And the adjusting member 15 is inserted by the leaf spring 17i.
And the adhesive 21 adheres to the surface of the adjusting member 15. At the same time, the vertical frame 19
The engagement projection 19e at the tip of the engagement projection piece 19d of A is fitted into the engagement recess 17g of the vertical sash 17A, and the engagement projection of the vertical sash 17A is inserted into the engagement recess 19g of the vertical frame 19A. 17h is inserted.

For mounting the beam cover 32, the beam cover 32 is first assembled into a rectangular frame surrounding the window glass 26, and is pressed against the aluminum beam body 31 from the indoor side in the same manner as described above. Then, the beam cover 32
The one end portion (fitting convex portion) 32 b is
And the rib (engaging projection) 31c of the aluminum beam main body 31 is fitted into a groove (fitting recess) 32a provided at the other end.

Hereinafter, the effect of the window frame mounting structure of the present embodiment will be described.

In the window frame mounting structure of this embodiment, as described above, the window frame 18 and the beam cover 32 can be easily mounted at predetermined positions by one-touch operation from the indoor side. Therefore, it is possible to omit the use of the end material for positioning the window frame as in the related art. Therefore,
The types of members to be used can be reduced, the on-site construction can be simplified, and industrialization can be further promoted.

Further, since the window frame 18 and the crosspiece cover 32 are made of the above-described molded material, all of the portions exposed to the indoor side (excluding the window glass 26) have a woody appearance. The texture is as if it were made of natural wood. As a result, the window space with the warm and gentle texture of wood is provided, which enhances the sense of quality and solidity, and the surrounding indoor scenery (wall panels, furniture, etc.)
In harmony with the interior, it is possible to improve the aesthetics of the room.

Further, since the window frame 18 and the crosspiece cover 32 are obtained by molding a mixture of the above-mentioned cellulose-based fine particles and a resin material, the conventional natural wood can be processed or combined. Its moldability is remarkably superior to that of the polished one. Therefore, as shown in the above-described embodiment, the engaging portion (the fitting convex portion 19) can be easily joined with the aluminum sash 16 with one touch.
e, 32b, even complex shapes with fitting recesses 19g, 32a) can be easily formed.

The window frame 18 has a prismatic portion 19a.
Is provided with an adhesive recess 19j, so that when the window frame 18 is mounted, the holding piece 19c or the adjusting material 1
When the uncured or semi-cured adhesive 21 applied to the surface of the fluid 5 flows and flows toward the inside of the room, the outflow can be accommodated. Therefore, the adhesive 21
Is prevented from oozing out on the surface of the window frame 18 and contaminating the surface and causing unevenness in the thickness of the adhesive layer, thereby helping to maintain the aesthetic appearance of the mounting structure of the window frame and maintain the adhesive performance.

Further, as described above, the mixture was obtained by extrusion or injection molding a mixture obtained by mixing the cellulose-based fine particles having the inorganic pigment carried on the surface thereof with the resin material after the grinding treatment. In the molding material, the surface is made sufficiently white by the white pigment supported on the surface, the color adjustment in the secondary processing is simplified, and a beautiful woody material is easily imparted. Unlike the fibrous material obtained by directly pulverizing the powder into a fine powder, the surface has little cilia and becomes granular, so that the surface of the plate material has no fuzz and feels good.

In addition, since the cellulose-based fine particles are not fibrous but granular, the fibrous portions are entangled to form a dumpling or cotton when mixed and dispersed. The pigments are dispersed in an independent state, so that the pigment-carrying powder particles themselves have extremely good dispersibility in the forming resin, and thus the obtained molding material is of a sufficiently uniform material.

Further, since the cellulosic fine powder particles are not fibrous but granular, the expansion and contraction caused by adsorbing or releasing water (including moisture) and solvent as fibrous wood powder is extremely large. Thus, a molding material containing the same is extremely excellent in dimensional stability.

In addition, since the cellulose-based fine particles are used as an aggregate with a grinding treatment and a pigment carried on the surface, adsorption and suction of the resin by the fine particles are extremely reduced, and molding distortion is caused. Is almost gone.
Further, in this molding material, since the cellulose-based fine particles carry the pigment and thus have improved heat resistance as compared to before the loading, the cellulose-based fine particles such as wood powder are simply compounded and molded. As compared with the case, the heat influence during molding is small, and thus the deterioration such as a change in color or shape is suppressed. In addition, by supporting the pigment, the surface of the cellulosic fine powder particles is covered, thereby suppressing the release of glycine and wood acid contained in the fine powder particles during molding. Molding defects due to release are prevented.

Further, in this molding material, the surface area of the cellulose-based fine particles supports the pigment,
It is larger than ordinary wood flour, and therefore, the degree of adhesion between the fine particles and the resin in the molding material is increased. Further, also at the time of molding, the resin containing fine cellulose particles of the present invention is excellent in fluidity compared with the resin mixed with wood powder, so that the extrusion pressure and the injection pressure can be set low.

In the case of the window frame 18 and the rail cover 32 manufactured by applying a surface treatment to such a molding material and then applying a paint, the surface of the molding material after molding is subjected to a grinding treatment. The white inorganic pigment-carrying cellulose-based fine particles located on the outer surface of the grinding surface are shaved, and the inner surface of the cellulose fine particles faces the grinding surface by shaving the pigment-carrying portion, so that the feel of the surface of the molding material is improved. It is soft and rich in woodiness because the cellulose-based fine particles themselves have hygroscopicity. Further, by applying the paint to the grinding surface facing the inner surface of the cellulose-based fine particles, the paint is directly sucked into the cellulose-based fine particles, whereby the suction of the paint into the molding material and the glue are good. Become.

Further, since the window frame 18 and the crosspiece cover 32 contain fine cellulose particles, they can be cut or nailed sufficiently with a saw, and can be handled in substantially the same manner as wood. Therefore, when it is used as a decorative material for a house or the like, construction such as installation at the site becomes extremely easy. In addition, since the window frame 18 and the crosspiece cover 32 contain cellulose-based fine particles, the application of the coating material to the molding material is firm, and a product having a sufficiently uniform coating film without partial peeling is provided. Become.

Further, when a paint containing a finely ground cellulosic powder is used as the paint, unlike the matte surface made of silica or the like, the color tone unique to the pigment used in the paint is obtained without reducing white turbidity. And a matte colored surface is obtained. Furthermore, if a mixture of finely ground cellulose particles is used as the coating material, the dispersibility of the fine particles is good, so that the brown pigment imparting a woody tone is well dispersed in the coating material, and thus the obtained paint is obtained. The painted surface has no unnatural color unevenness, and has a wood-like appearance having only a natural color tone change due to embossing or the like.

Further, the prismatic portion 19a of the window frame 18
Is provided with several hollow portions 19b, so that the hollow portions 19b can be used as storage spaces for house facilities such as a power cord and a power outlet. As a result, it is possible to prevent the housing equipment from being exposed indoors, and to maintain the aesthetic appearance of the indoors.

[0071]

As described above, according to the window frame mounting structure of the present invention, the window frame can be easily mounted at a predetermined position by a one-touch operation simply by pushing the window frame from the indoor side, and the positioning can be performed. It is possible to simplify the on-site construction by omitting the use of offcuts for use. In addition, since the window frame is formed by extrusion or injection molding of a mixture obtained by mixing a cellulose-based fine particle carrying an inorganic pigment with a resin material, it is excellent in moldability and can be easily processed into a desired shape. be able to. Also, the obtained window frame has a woody appearance similar to natural wood, so by attaching this window frame to the part exposed toward the indoor side, it has the warmth and gentle texture of wood, It is possible to provide a profound and luxurious window space and enhance the beauty of the room by harmonizing the window space with the surroundings. In addition, since the window frame is provided with an adhesive recess, even when the adhesive used for bonding the window frame and the adjusting agent flows out, the outflow is stored in the adhesive recess. To prevent the adhesive from seeping out of the window frame surface and the resulting contamination of the surface,
Therefore, the beauty of the room can be maintained.
