Description

The present invention relates to sweeps.

In a building such as a house, a stile is installed at a stepped portion. The stile is a decorative material provided at the end of the higher member of the stepped portion. For example, in an entrance, there is a step between the floor of the entrance (hereinafter referred to as "entrance floor") and the floor of the corridor (hereinafter referred to as "floor"). At the higher end of the part where there is a step, a construction material called an entrance frame is attached. Moreover, in a staircase, there is a difference in level between the floor on the upper floor and the treads on the lower step. At the higher end of the stepped part, a fixture called the upper frame is attached. Some of the stiles have a base material made of laminated lumber and decorative materials attached to the front and top surfaces. The base material has high water absorption, and the moisture absorbed by the base material may cause mold to grow on the decorative material, causing it to discolor or rot. Especially during construction, mortar is applied to the entrance floor, and the entrance frame is installed on the mortar. In such a case, the base material of the entrance stile absorbs the moisture of the mortar, causing mold or the like to grow on the decorative material, thus giving rise to problems with the design of the entrance stile.

Patent Literature 1 discloses a floor member that is most suitable for an entrance door frame. The floor member described in Patent Document 1 forms a waterproof layer on the back surface of the wooden base material. As a result, the base material is prevented from absorbing moisture under the floor, making the base material less likely to rot, and discoloration due to the generation of mold can be prevented.

Japanese Utility Model Laid-Open No. 63-187664

By the way, in the limited space of the entrance hall where guests are invited, it is desirable to improve the appearance. For this reason, if a waterproof layer is provided on the back surface (bottom surface) opposite to the top surface, as in the floor member described in Patent Document 1, the exposed waterproof layer may be visible, which may impair the design of the entrance. be. In particular, the back side of the upper stile is a portion that is easily visible to people coming up from downstairs.

In addition, the floor member described in Patent Document 1 is provided with a moisture-proof layer on the rear surface, which is not the part that directly contacts the mortar containing moisture. And since the material is increased, the cost is increased, and the cost effectiveness is lowered. Furthermore, the treatment of the rear surface may cause the front decorative surface to be scratched during the manufacturing process. In addition, Patent Document 1 specifically exemplifies a waterproof layer formed by applying a urethane resin paint, but such a waterproof layer has a low moisture-proof effect, and the coating thickness or coating unevenness at the time of production. There is a problem that variations in moisture-proof performance occur. Furthermore, since the paint turns yellow due to ultraviolet rays or deterioration over time, there is a concern that the design will deteriorate over time, and there is also the problem that cracks in the paint film may reduce the moisture-proof performance.

Accordingly, one example of the object of the present invention is to provide a fitting material used for a stile that does not impair the design, makes the base material less likely to rot, and can prevent discoloration due to mold growth.

In order to achieve the above object, the construction material in one aspect of the present invention is

ADVANTAGE OF THE INVENTION According to this invention, the fixture used for a stile can be implement|achieved which can make a base material hard to rot, and can prevent discoloration by generation of mold, without impairing a design.

FIG. 1 is a diagram showing a state in which a fixture is constructed. FIG. 2 is a diagram showing the fixture of the embodiment. FIG. 3 is a diagram showing a chamfered portion formed on the moisture-proof sheet.

An embodiment of the present invention will be described below with reference to the drawings.

The fitting material of the present embodiment is used, for example, as a stile, more specifically, as a stile for entrances or an upper stile for stairs. In the following description, it is assumed that the fitting material is used for the door frame.

FIG. 1 is a diagram showing a state in which a construction material 1 is constructed.

The fixture 1 is installed at a corner portion rising from the entrance 100 to the floor 101 in the room. The entrance 100 is constructed with finishing materials such as tiles or cement. A foundation 103 is constructed on a foundation 102 in a portion rising from the entrance 100 to the floor 101 . A joist 104 is provided on the base 103, and a floor base 105 and a floor decorative material 106 are applied to the joist 104. - 特許庁

A fixture 1 is constructed in the corner portion. A wooden base 107 is provided on the foundation 102 . A mortar 108 is provided on the front surface of the foundation 102 (on the entrance 100 side). The fixture 1 is placed on the wood base 107 and the mortar 108 and fixed to the wood base 107 and the base 103 with a urethane-based adhesive.

The fixture 1 of the present embodiment has a structure capable of suppressing the occurrence of mold, discoloration, etc. due to moisture absorption of the mortar 108 when constructed as shown in FIG.

FIG. 2 is a diagram showing the fixture of this embodiment. In FIG. 2, a part of the fixture 1 is enlarged and displayed.

The building material 1 has a wooden base material 10. - 特許庁The wooden base material 10 is columnar. The wood substrate 10 is, for example, solid wood, laminated wood, plywood, LVL (Laminated Veneer Lumber), MDF (Medium Density Fiberboard), or HDF (High Density Fiberboard). ), or may be formed of particle board, OSB (Oriented Strand Board), a laminate thereof, or the like.

In the following description, when the fixture 1 is constructed, the surface of the wooden base material 10 which is the upper surface when constructed and which becomes part of the floor 101 is referred to as the top surface. Further, the surface on the opposite side of the top surface, which is the side of the mortar 108 and the foundation 102 when the construction material 1 is constructed, is called the bottom surface. Further, the surface of the wooden base material 10 which is adjacent to the top surface and the bottom surface, faces the entrance 100 side when the construction material 1 is constructed, and is substantially perpendicular to the floor of the entrance 100 is referred to as the front surface.

A top surface decorative material 11 is provided on the top surface of the wooden base material 10 . The ceiling decorative material 11 constitutes a part of the floor 101 when the construction material 1 is constructed. The top surface decorative material 11 has a thickness of, for example, approximately 0.1 mm to 5.0 mm. Although the material of the top surface decorative material 11 is not particularly limited, it is formed of, for example, woody decoration such as sliced veneer or sawn board, resin sheet such as olefin sheet or vinyl chloride sheet, or paper sheet on which a pattern is printed.

A front decorative material 12 is attached to the front surface of the wooden base material 10.例文帳に追加The front decorative material 12 has a thickness of, for example, approximately 0.1 mm to 5.0 mm. Although the material of the front decorative material 12 is not particularly limited, it is formed of, for example, wood decoration such as sliced veneer or sawn board, resin sheet such as olefin sheet or vinyl chloride sheet, or paper sheet on which a pattern is printed. As shown in the enlarged portion of FIG. 2 , the end face of the front decorative member 12 on the bottom side of the wooden substrate 10 is substantially flush with the bottom surface of the wooden substrate 10 .

A moisture-proof sheet 13 is attached to the bottom surface of the wooden base material 10 . The bottom surface of the wooden base material 10 and the end surface of the front decorative member 12 on the bottom surface side are flush with each other. The moisture-proof sheet 13 is attached so as to cover the bottom surface of the wooden base material 10 and the end surface of the front decorative material 12, which are flush with each other. As will be described later, the moisture-proof sheet 13 is a member that prevents the wooden base material 10 and the front decorative material 12 from absorbing moisture from the mortar 108 when the construction material 1 is placed on the mortar 108 . Therefore, the moisture-proof sheet 13 is made of a moisture-proof and water-resistant material. The moisture-proof sheet 13 has a moisture-proof/water-proof performance such that the moisture permeability measured according to JIS Z0208 is 30 g/(m ² 24 h) or less, more preferably 20 g/(m ² 24 h) or less, and still more preferably 10 g. /(m ² ·24h) or less is preferable. This is because the smaller the moisture permeability value, the higher the effect against discoloration, decay, or mold growth due to moisture migration.

As the moisture-proof sheet 13, for example, polyethylene resin, polypropylene resin, polyethylene terephthalate resin, polystyrene resin, polyvinyl chloride resin, acrylonitrile-butadiene-styrene copolymer synthetic resin (ABS resin) is molded into a sheet or plate. mentioned. The moisture-proof sheet 13 may be formed by laminating and integrating a plurality of these resins, or may be a metal layer such as aluminum foil (a sheet of metal). Furthermore, laminated paper obtained by laminating resin and paper, or polysand paper may be used. From the viewpoint of moisture resistance, it is conceivable to apply not only sheet-like materials but also resin paint, but resin paint has a low moisture-proof effect, and variations in moisture-proof performance occur due to coating thickness or uneven coating during manufacturing. There is a problem that Furthermore, since the paint turns yellow due to ultraviolet rays or deterioration over time, there is concern that the design may deteriorate over time, and cracks in the paint film may reduce moisture resistance.

The moisture-proof sheet 13 has a thickness of about 0.1 mm to 1.0 mm, preferably 0.1 mm to 0.5 mm, and still more preferably 0.1 mm to 0.3 mm. Although the method of adhering the moisture-proof sheet 13 is not particularly limited, for example, a water-based adhesive, a resin-based adhesive, a hot-melt adhesive, or an adhesive is used.

A wooden sheet 14 is attached to the surface of the moisture-proof sheet 13. - 特許庁The material of the wood sheet 14 is not particularly limited as long as strength and durability are ensured, and examples thereof include veneer, veneer, sawn board, and fiberboard such as MDF and HDF. The thickness of the wooden sheet 14 is not particularly limited, although a thinner one is preferred in consideration of material costs and workability during manufacturing. The wood sheet 14 has a thickness of 0.1 mm to 5.0 mm, preferably 0.1 mm to 3.0 mm, and still more preferably 0.1 mm to 1.0 mm. The method of adhering the wood sheet 14 is not particularly limited, but for example, a water-based adhesive, a resin-based adhesive, a hot-melt adhesive, or an adhesive is used.

When the fixture 1 to which the moisture-proof sheet 13 and the wood sheet 14 are attached is placed on the mortar 108 , moisture in the mortar 108 is absorbed by the wood sheet 14 . However, since moisture-proof sheet 13 covers the bottom surface of wooden base 10 , moisture in mortar 108 is prevented from penetrating into wooden base 10 . As a result, the generation of mold or the like on the front decorative material 12 due to permeation of water from the wooden base material 10 to the front decorative material 12 is prevented.

In addition, since the moisture-proof sheet 13 covers the end surface of the front decorative material 12, even if the front decorative material 12 is installed directly above the mortar 108, the moisture of the mortar 108 will be absorbed by the front decorative material. Direct penetration into 12 is prevented. In some cases, the mortar 108 is applied after the construction material 1 is applied. In this case, the mortar 108 is often applied to just below the front decorative material 12, and the mortar 108 is applied more than the case where the fixture 1 is placed and applied after the mortar 108 is applied and dried to some extent. contains a lot of water. Therefore, the fact that the moisture-proof sheet 13 covers the end faces of the front decorative material 12 is particularly effective in preventing direct penetration of moisture into the front decorative material. As a result, the generation of mold or the like on the front decorative material 12 is prevented. In other words, the moisture-proof sheet 13 prevents moisture in the mortar 108 from penetrating indirectly into the front decorative material 12 through the wooden base material 10 and from penetrating directly into the front decorative material 12 .

Moreover, by providing the wooden sheet 14 on the surface of the moisture-proof sheet 13, the design of the bottom side of the building material 1 can be maintained. Furthermore, since the wood sheet 14 has a function of suppressing expansion and shrinkage due to the temperature of the moisture-proof sheet 13 (especially heat during drying in the coloring and painting process), the moisture-proof sheet 13 is prevented from peeling off from the wooden base material 10. can do.

A chamfered portion 14</b>A inclined with respect to the bottom surface of the wooden substrate 10 is formed at the end of the wooden sheet 14 . By forming the chamfered part 14A, it is possible to remove burrs or fluff generated at the time of manufacturing, prevent clothes from being caught after construction of the construction material 1, and also prevent the wood sheet from being cornered during transportation of the construction material. 14 cracks can be prevented.

The chamfering process for forming the chamfered portion 14A includes C surface processing (45°) formed only with a flat surface, thread surface processing, chamfering at an angle other than 45°, R surface processing including curved surfaces, and flat surfaces. Chamfering of a shape combining curved surfaces may be used.

Further, the chamfered portion 14A may be formed in the wooden sheet 14 in advance, or may be formed when the wooden sheet 14 is attached to the surface of the moisture-proof sheet 13 . Further, as shown in FIG. 3, the moisture-proof sheet 13 may also be formed with a chamfered portion 14A. FIG. 3 is a diagram of the chamfered portion 14A formed on the moisture-proof sheet 13. As shown in FIG. In this case, the chamfered portions 14A are formed at the ends of the wood sheet 14 and the moisture-proof sheet 13 so that the moisture-proof sheet 13 remains on the end face of the front decorative material 12 . Therefore, even when the chamfered portion 14A is formed on the moisture-proof sheet 13, the moisture in the mortar 108 can be prevented from directly penetrating into the front decorative material 12. FIG.

Next, a method for manufacturing the fixture 1 will be described.

First, the front decorative material 12 is attached to the front surface of the wooden base material 10 . The end surface of the front decorative member 12 on the bottom side of the wooden substrate 10 is substantially flush with the bottom surface of the wooden substrate 10 . Then, the attached front face decorative material 12 is deburred.

Next, a moisture-proof sheet 13 is attached to the bottom surface of the wooden base material 10 . The method of adhering the moisture-proof sheet 13 is not particularly limited. At this time, the moisture-proof sheet 13 is attached so as to cover the bottom surface of the wooden substrate 10 and the end surface of the front decorative material 12 flush with the bottom surface. After that, the moisture-proof sheet 13 is deburred.

Next, a wooden sheet 14 is attached to the surface of the moisture-proof sheet 13 . The method of bonding the wood sheet 14 is not particularly limited. Then, the wooden sheet 14 is chamfered. The chamfering process may be a process using a cutting tool or a process using sandpaper. Note that the moisture-proof sheet 13 and the wooden sheet 14 may be integrated in advance.

A top surface decorative material 11 is attached to the top surface of the wooden base material 10.例文帳に追加Then, the attached top surface decorative material 11 is deburred. Also, the top surface decorative material 11 is chamfered. After that, the fixture material 1 is colored, dried, painted, and dried.
