BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction member, and more specifically, to prevent the decorative paper from being broken or wrinkled when the decorative paper is attached to the substrate and when the substrate expands and contracts due to a change in humidity. The present invention relates to a feature member capable of improving the performance.

2. Description of the Related Art A construction member is, for example, a skirting board that hides a seam between a floor and a wall board, a peripheral edge that hides a seam between a ceiling and a wall board, a parting time that gives an accent to a floor board or a wall board, or a wall board. It is a plate member for beautifully decorating a seam of a different member such as a window frame that hides a seam between the window and a window, and decorative paper is adhered to a surface of a substrate serving as a main body. FIG. 5 shows a skirting board 100 which is an example of a construction member. A decorative paper 102 made of paper is adhered to an entire surface of a substrate 101 made of plywood except for a bottom surface thereof with an adhesive. The substrate 101 has the exposed corner 1 at one end.
01a is chamfered at approximately 45 degrees, and its surface 10
1b, a single nail driving groove 103 having a rectangular shape in cross section is formed.

[0003]

However, in the conventional baseboard 100, when the decorative paper 102 is attached to the substrate 101, the decorative paper 102 is pressed against the surface of the substrate 101 by a roller. Sometimes, it is difficult to accurately dimension the decorative paper 102 that matches the shape of the substrate 101,
There is a problem that stress concentrates on the corner 101a chamfered at 45 degrees and the corner at a right angle of the nailing groove 103, and local wrinkles a and tears b occur on the decorative paper 102. In addition, although the baseboard 100 expands and contracts due to a change in the amount of moisture absorbed and released according to the change in humidity, the substrate 10 having a relatively large amount of moisture absorbed and released.
When the decorative paper 1 is extended, the decorative paper 102 having a low rigidity and a small amount of water absorption and release cannot follow the same, and similarly, stress is concentrated on the corner 101a of the substrate 101 and the corner of the nailing groove 103, and wrinkles a
There is a problem that a tear b occurs. Further, the conventional baseboard 100 has a nail driving groove 103 exposed on its surface.
Since the corners including were sharp, it was hard in design and there was an image that it hurt when it hits. It should be noted that there is a similar problem in the corner portion 101a and the nailing groove 103 also in other construction members such as the periphery and parting. The present invention has been made in view of such circumstances, and it is possible to prevent the decorative paper from being broken or wrinkled when the decorative paper is attached to the substrate and when the substrate expands and contracts due to a change in humidity. The purpose is to provide.

[0004]

According to the present invention, there is provided a semiconductor device comprising:
The feature member described is a medium-density fiber board, a particle board, a plywood or a laminate member in which the surface of a wooden board made of a veneer laminated material is covered with decorative paper. , And have a circular cross section. Here, the arc-shaped cross section includes a circle, an ellipse, and other irregularly curved shapes.

[0005]

According to the first aspect of the present invention, there is provided a corner member which is externally exposed when the decorative member is attached to the substrate by a roller or the like, or when the substrate is stretched more than the decorative paper due to a change in humidity. Since the section has an arcuate cross section, even if the decorative paper is pressed against the substrate with a large pressure by the roller, or if the substrate is stretched more than the decorative paper due to a change in humidity, the decorative paper is less likely to wrinkle or tear. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the accompanying drawings to facilitate understanding of the present invention. Here, FIG. 1 is an enlarged perspective view of the construction member according to the first embodiment of the present invention, FIG. 2 is an enlarged perspective view of the construction member according to the second embodiment of the present invention, and FIG. FIG. 4 is an enlarged perspective view of a feature member according to a third embodiment of the present invention, and FIG. 4 is an enlarged perspective view of a feature member according to a fourth embodiment of the present invention.

As shown in FIG. 1, a skirting board 10 which is an example of a construction member according to a first embodiment of the present invention has the entire surface except for the bottom surface of a substrate 11 covered with decorative paper 12.
One end has a corner portion 11b on the side of the surface 11a that is exposed to the outside, and a nail driving groove 13 having a rectangular shape in cross section is formed near one end of the surface 11a.

The substrate 11 is a plate made of a medium density fiberboard (MDF) having a length of 3950 mm, a height of 65 mm and a depth of 9 mm. The corner portion 11 b has an arc-shaped cross section with a radius of curvature of 6 mm, while the nailing groove 13 is formed. Is 14 m from one end of the substrate 11
A rectangular groove having a width of 9 mm and a depth of 4 mm formed at a surface position of m, and each corner 13a has an arc-shaped cross section with a radius of curvature of 2 mm. Other materials for the substrate 11 include, for example, plywood, laminated veneer (LVL, LVB)
And particle board.

The decorative paper 12 is obtained by printing a wood grain pattern on thin paper having a weight of 30 g / m ² and then applying a polyurethane resin paint thereto. It is stuck on the substrate 11 by a wrapping device having rollers. Note that decorative paper 12
In addition, a paper weighing about 23 to 55 g / m ² , synthetic paper or a paper reinforced with a backing paper attached to the back surface of the paper including the thin paper is used. After printing on a desired pattern with ink, a material coated with a synthetic resin paint such as an amino alkyd resin or a polyurethane resin can be employed. As the adhesive, an epoxy resin-based adhesive, a synthetic rubber-based adhesive, or the like can be used in addition to the vinyl acetate-based resin emulsion-based adhesive.

The application of the decorative paper 12 to the substrate 11 is performed by pressing a roller from above on the decorative paper 12 with a large force and moving the same. A large pulling force is applied in the direction of travel. However, as described above, since the corners 11b exposed to the outside and the corners 13a of the nailing groove 13 are formed in an arc shape, the stress applied to these parts is dispersed, and at least when the wall is mounted. Baseboard 1 visible from outside
It is difficult for such a wrinkle or tear to occur in the portion of 0. It should be noted that even if wrinkles or tears occur at other corners, they will be hidden when mounted on the wall surface, so there is no problem.

The skirting board 10 thus manufactured is attached to the seam between the floor and the wallboard by driving a nail into the nail driving groove 13. The baseboard 10 expands and contracts by absorbing and releasing moisture due to a change in humidity. At this time, the substrate 11 expands and contracts more greatly than the decorative paper 12 due to a difference in material. As a result, even if the substrate 11 absorbs moisture and expands greatly, the decorative paper 12 expands only a little, and a large stress tends to be applied to the corners 11b and 13a. However, as described above, since these portions are arc-shaped, the stress is dispersed without being concentrated. Therefore, local wrinkles and tears of the decorative paper 12 can be avoided. In addition, since the corner at the back side of the nailing groove 13 is an arc-shaped corner curved inward, when the substrate 11 is extended, the corresponding decorative paper 12 is apt to wrinkle instead of tearing. (See FIG. 5). Further, since the corners 11a and 13a exposed to the outside have a gentle arc shape, a soft image can be given to the baseboard 10, and the appearance of the inner and outer walls of the building can be improved.

Next, a second embodiment of the present invention will be described with reference to FIGS.
Working members according to the fourth to fourth embodiments will be described. The second embodiment shown in FIG. 2 is an example in which the construction member of the present invention is applied to a peripheral edge 20 which hides a joint between a ceiling and a wall plate, and the third embodiment shown in FIG. The fourth embodiment shown in FIG. 4 has no nailing groove 13 and has a long width that conceals the seam between the wall plate and the window without the nailing groove 13. This is an example of application to a window frame 40.

Although the present invention has been described with reference to the drawings, the present invention is not limited to this embodiment, and any change in the design without departing from the scope of the present invention is included in the present invention. In the embodiment, the base member, the periphery,
Although a parting-out window and a window frame have been illustrated, the invention is not limited thereto, and may be applied to any other construction members such as a decorative bar attached around an opening such as a door. Further, the corners exposed to the outside of the substrate are not limited to those having the radial dimensions of the embodiment, but may be arcuate in cross section having a radius of curvature of 1 mm or more. In addition, the corners may have an elliptical shape or another irregularly curved shape, even if the cross section is not a perfect circle.

[0014]

According to the first aspect of the present invention, since the corner portion exposed to the outside when the wall is mounted has an arcuate cross-section, when the decorative paper is attached to the substrate by a roller or the like, Even when the substrate elongates to a greater extent than the decorative paper due to a change in humidity, the stress applied to the corners is dispersed, so that wrinkles and tears on the decorative paper can be prevented. In addition, the corners become gentle, and a soft image can be given to the construction member.
