BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partition panel having a vinyl chloride sheet attached to its surface.

[0002]

2. Description of the Related Art A partition panel uses a core, a gypsum board, etc. as a backing material, and a steel plate is adhered to the surface as a surface material. In addition, such a panel with a cloth further attached to the surface is used, and has a higher texture than a panel in which a steel plate is exposed on the surface, and the partition constructed by constructing the panel is used in an office or a room. It warms the atmosphere and changes it to a calm state. By the way, an adhesive is applied to the back surface of the cloth, and the cloth is bonded to the panel surface material within the usable time. Needless to say, the application of the adhesive may be performed on the panel side, but not only the adhesive has to be applied, but also the adhesive has a usable time that can be pasted, which becomes a bottleneck in the panel manufacturing process.

Further, the conventional cloth-attached panel is a panel in which cloth is simply attached to the surface material, and the surface thereof is also a flat cloth surface. The use of the cloth surface improves the texture of the panel, but it depends on the material of the cloth itself and the weaving / knitting structure, and unless the kind of the cloth is changed, only uniform panels can be manufactured. On the other hand, the cloth-bonded panel is increasing its utility value in that it has a better sound absorbing effect than a panel whose surface is covered with a steel surface, but it is never enough to improve the office environment. It's not.

[0004]

[Problems to be Solved by the Invention] As described above, the above-mentioned problems remain in the conventional cross-attached panel. The problems to be solved by the present invention are these problems, and it is possible to form a pattern with unevenness on the surface as well as the texture of the surface, further improve the sound absorbing effect, and not use an adhesive. We provide a vinyl sheet-attached panel that enables the panel to be manufactured without restrictions due to usage time.

[0005]

[Means for Solving the Problems] A vinyl sheet-attached panel of the present invention is a panel formed by attaching a vinyl chloride sheet to a surface material, and the vinyl chloride sheet is a high frequency current without an adhesive. To partially weld. That is, if a vinyl chloride sheet is laid on the panel surface, an electrode is placed on the panel and pressure is applied, and electricity is applied in this state, the vinyl chloride sheet is melted and welded. In this case, the welded portion should be concave compared to other areas, the unwelded area should be convex, and the concaved portion should be in close contact with the panel surface, but the raised area should be in close contact with the surface. Instead, a small space (gap) is formed between them.

Here, when a vinyl chloride sheet is welded to a steel surface material, a vinyl chloride sheet is laid on and partially welded to the surface material subjected to a vinyl chloride coating treatment. When the panel surface is made of wood, etc., it is welded through urethane foam. In addition to vinyl chloride sheets, vinyl chloride sheets include sheets that are woven and knitted so that vinyl chloride is exposed on the back or front and back surfaces, as well as sheets that are made of vinyl chloride alone. Those with coating treatment are also included.

[0007]

The panel of the present invention is a panel to which a vinyl chloride sheet is adhered as described above. Since the vinyl chloride sheet is partially welded by using a high frequency current, it is formed in a welded area and a non-welded area. The uneven surface to be covered covers the panel surface as a kind of three-dimensional pattern. For that purpose, it is necessary to fabricate the shape of the electrode to be used, but
The gap formed between the surface material and the convex non-welding region acts as a sound absorbing effect, and is significantly improved over the sound absorbing effect of the conventional cloth sticking panel. Hereinafter, an embodiment of a vinyl sheet sticking panel according to the present invention will be described in detail with reference to the drawings.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of a vinyl sheet-attached panel of the present invention, in which 1 is a core, 2 is a surface material,
3 is a vinyl chloride sheet, 4 is a reinforcing material, and 5 is a claw. Steel surface materials 2 and 2 are attached to both surfaces of the core 1, and reinforcing materials 4 having a U-shaped cross section are attached to both ends of the core 1, and the inside of the reinforcing material 4 is attached. The claw 5 is fixed by welding. Such a panel is often used as a low partition panel, and the above surface materials 2, 2 are used.
A panel with a cloth attached on top is also used.

In the panel of the present invention, a vinyl chloride sheet 3 is laid on the surface material 2 and partially welded. In this case, the surface material 2 is subjected to a vinyl chloride coating treatment to enhance the welding force to the surface material 2. In the figure, b shows the surface of the panel, in which a kind of three-dimensional pattern is formed on the panel surface, and the recesses 6 ... Which form a rhombus are arranged vertically and horizontally at regular intervals. That is, the concave portion 6 is a region welded to the surface material 2 and the other portions are not welded, so that the convex portion is formed. The welding of the vinyl chloride sheet 3 uses a high-frequency current, and the diamond-shaped electrode is pressed from above the vinyl chloride sheet 3 laid on the surface material 2, and if current is applied in that state, the electrode portion is melted and the surface It is welded to the material 2.

FIG. 2 is a partially enlarged view of the cross section of the panel, but the vinyl chloride sheet 3 welded to the surface material 2 has a recess 6
And the convex portion 7 is formed and is welded to the surface material 2 in the region of the concave portion 6, and the convex portion 7 leaves a gap 8 between the surface material 2 and the convex portion 7.
When the vinyl chloride sheet 3 is melted in the region that becomes the concave portion 6, the vinyl chloride sheet 3 spreads to the periphery, and as a result, the convex portion 7 that becomes the non-welded region rises with a gap 8 left. Therefore, the panel surface has a three-dimensional pattern in which the diamond-shaped recesses 6 are arranged vertically and horizontally. Of course, if the shape of the electrode is changed, the shape can be freely made, such as a circle or a triangle.

FIG. 3 shows another embodiment of the present invention, in which the whole panel is constructed of plywood 9, and in this case, the urethane foam 10 is not directly laid on the surface of the plywood 9 Are welded through. As in the case of the above-mentioned embodiment, the welded state forms the concave portion 6 and the convex portion 7.
As described above, the vinyl sheet-attached panel of the present invention is one in which a vinyl chloride sheet is laid on the panel surface and partially welded, and the following effects can be obtained.

[0012]

The vinyl sheet-attached panel of the present invention is a panel formed by welding a vinyl chloride sheet on the panel surface, and the welding uses a high frequency current. Therefore, it is sufficient to lay a vinyl chloride sheet on the panel surface and press the electrodes from above to energize it, and there is no adhesive application process like the conventional cross-attached panel, and it is possible to attach the adhesive. Since there is no restriction on the usage time, the panel manufacturing process is simplified.

Then, a concave portion and a convex portion are formed on the surface of the vinyl chloride sheet adhered by being partially welded, and if an electrode having a predetermined shape is used, these concave and convex portions form a predetermined three-dimensional shape. The pattern is formed, and compared with the conventional flat panel, not only the texture but also a high-class feeling is brought about.
On the other hand, in the convex portion that does not become the welding area, a gap is left between the panel surface material and the gap, which exhibits a sound absorbing effect,
The sound absorbing function is significantly higher than that of the conventional cloth-attached panel.
