Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fabrication member, and more specifically, it can prevent the decorative paper from tearing or wrinkling when the decorative paper is attached to the substrate or when the substrate expands or contracts due to humidity change, and the design can be improved. Regarding the fabrication member.

[0002]

[Prior art]

 The featured members include, for example, a skirting board that hides the joint between the floor and the wallboard, a rim that hides the joint between the ceiling and the wallboard, a parting line that adds an accent to the floorboard or the wallboard, and a joint between the wallboard and the window. This is a plate member that beautifully makes up the seams of different members such as window frames that hide the seams, and decorative paper is attached to the surface of the substrate that is the main body. FIG. 5 shows a skirting board 100, which is an example of a fabrication member, and a decorative paper 102 made of paper is adhered to the entire surface of the substrate 101 made of plywood except the bottom surface with an adhesive. The exposed corner portion 101a of the base plate 101 is chamfered at approximately 45 degrees, and only one rectangular nailing groove 103 is formed on the surface 101b in a sectional view.

[0003]

[Problems to be solved by the device]

 However, in the conventional skirting board 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 the roller. Since it is difficult to accurately measure the size of the fitted decorative paper 102, stress concentrates on the corners 101a chamfered at 45 degrees and the corners at right angles to the nailing groove 103, and local wrinkles are formed on the decorative paper 102. There was a problem that a and tear b occurred. Further, the skirting board 100 expands and contracts due to a change in moisture absorption / desorption amount with a change in humidity, but when the substrate 101 having a relatively large moisture absorption / desorption amount expands, the rigidity is poor and the moisture absorption / desorption amount is also increased. The small decorative paper 102 cannot follow, and similarly, stress concentrates on the corners 101a of the substrate 101 and the corners of the nailing groove 103, causing wrinkles a and tears b. Furthermore, since the conventional baseboard 100 has a sharp corner including the nailing groove 103 exposed on the surface, it is hard in design and has an image that it is painful when hit. In addition, also in other manufacturing members such as a rim and a parting, there was a similar problem in the corner portion 101a and the nailing groove 103. The present invention has been made in view of such circumstances, and it is possible to prevent tearing and wrinkling of the decorative paper when the decorative paper is attached to the substrate and when the substrate expands or contracts due to humidity change, and to improve the design. It is intended to provide a member.

[0004]

[Means for Solving the Problems]

 According to the above-mentioned object, the featured member according to claim 1 is a featured member for makeup in which the surface of a substrate is covered with a decorative paper, and the corners exposed to the outside at the time of attachment are configured to have an arcuate cross section. The featured member according to a second aspect is the featured member according to the first aspect, wherein the corner portion has an arcuate cross section with a radius of curvature of 1 mm or more.

【Example】

 Next, an embodiment of the present invention will be described with reference to the accompanying drawings to provide an understanding of the present invention. 1 is an enlarged perspective view of a featured member according to a first embodiment of the present invention, FIG. 2 is an enlarged perspective view of a featured member according to a second embodiment of the present invention, and FIG. 3 is a perspective view of the present invention. 3 is an enlarged perspective view of the featured member according to the third embodiment, and FIG. 4 is an enlarged perspective view of the featured member according to the fourth embodiment of the present invention.

As shown in FIG. 1, a skirting board 10 which is an example of a fabrication member according to the first embodiment of the present invention has a decorative paper 12 covering the entire surface of the substrate 11 except the bottom surface. A rectangular nailing groove 13 is formed in a cross section in a corner 11b on the surface 11a side exposed to the outside of one end and in the vicinity of one end of the surface 11a.

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

The decorative paper 12 is a thin paper having a weight of 30 g / m ² which is printed with a wood grain pattern by ink and then coated with a polyurethane resin coating, which is coated with a vinyl acetate resin emulsion adhesive. It is stuck on the substrate 11 by a lapping device having rollers. In addition, as the decorative paper 12, other paper having a weight of about 23 to 55 g / m ² , synthetic paper or paper including the above-mentioned thin paper, which is backed with a backing paper, is used. It is possible to use a paper that is printed with ink in a desired pattern on the surface of the paper and then coated with a synthetic resin paint such as amino alkyd resin or polyurethane resin. In addition to the vinyl acetate resin emulsion adhesive, an epoxy resin adhesive or a synthetic rubber adhesive can be used as the adhesive.

Adhesion of the decorative paper 12 to the substrate 11 is performed by pressing a roller from the decorative paper 12 with a large force to move the decorative paper 12, and at this time, the decorative paper 12 is attached to the decorative paper 12 at the same time as the application of the roller. A large pulling force is applied in the direction of travel. However, as described above, since the corners 11b that are exposed to the outside and the corners 13a of the nailing groove 13 are arc-shaped, the stress applied to these parts is dispersed and at least the wall mounting It is difficult for such wrinkles and tears to occur on the part of the skirting board 10 that is sometimes seen from the outside. Even if wrinkles or tears occur at other corners, they will be hidden when the wall is attached, so there is no problem.

The skirting board 10 thus manufactured is attached to the joint between the floor and the wall board by driving a nail into the nail driving groove 13. By the way, the skirting board 10 absorbs and releases water due to a change in humidity and expands and contracts. At this time, the substrate 11 expands and contracts greatly compared to the decorative paper 12 due to the difference in material. As a result, even if the substrate 11 absorbs moisture and greatly expands, the decorative paper 12 slightly expands, and a large stress tends to be applied to the corners 11b and 13a. However, as described above, since these portions have an arc shape, this stress is dispersed without being concentrated. Therefore, local wrinkles and tears of the decorative paper 12 can be avoided. Since the inner corner of the nailing groove 13 is an arcuate corner which is curved inward, when the substrate 11 is extended, the corresponding part of the decorative paper 12 is likely to be wrinkled rather than broken. (See FIG. 5). Further, since the exposed corners 11a and 13a have a gentle arc shape, a soft image can be given to the skirting board 10 and the appearance of the inner and outer walls of the building can be improved.

Next, a fabrication member according to second to fourth embodiments of the present invention will be described with reference to FIGS. The second embodiment shown in FIG. 2 is an example in which the featured member of the present invention is applied to the rim 20 for hiding the joint between the ceiling and the wall plate, and the third embodiment shown in FIG. An example of application to the parting line 30 which adds an accent to a floor plate or a wall plate without a nail, and the fourth embodiment shown in FIG. 4 also has a long width which hides the joint between the wall plate and the window without the nailing groove 13. It is an application example to the window frame 40.

The present invention has been described above with reference to the drawings, but the present invention is not limited to this embodiment, and even if there are design changes and the like without departing from the scope of the invention, the present invention is included. In the embodiment, a baseboard, a rim, a parting line and a window frame are exemplified as the working member, but the working member is not limited to this, and can be used as a working member such as a decorative bar attached around the opening of a door or the like. You may apply. Further, the corner portion exposed to the outside of the substrate is not limited to the radius dimension of the embodiment, and may be an arc-shaped cross section having a radius of curvature of 1 mm or more. Further, the corner may have an elliptical shape or other irregularly curved shape, instead of having a perfect circular cross section.

[0014]

[Effect of device]

 In the featured member according to claims 1 and 2, since the corners exposed to the outside when mounted on the wall have an arcuate cross section, when the decorative paper is adhered to the substrate by a roller or the like, a change in humidity occurs. As a result, even when the substrate is stretched to a greater extent than the decorative paper, the stress applied to the corners is dispersed, and thus wrinkles and tears can be prevented from occurring on the decorative paper. Also, the corners can be smoothed to give a soft image to the featured member.
