JPS5913979B2 - Hollow decorative material and its manufacturing method - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a hollow decorative material having chamfered corners, lightweight, and into which reinforcing bars can be easily inserted and fixed to maintain firmness, and a method for manufacturing the same.

Conventionally, decorative materials with chamfered corners were either laminated decorative materials made by inserting resin with the same wood grain pattern as the decorative sheet pasted onto the surface only in the corners, or laminated decorative materials made by inserting pieces of the same resin at intervals. A decorative sheet having the same wood grain pattern as the resin piece is attached to the surface of the laminated board inserted and assembled at
A hollow piece is formed by carving a U-shaped groove from the back side approximately at the center of the resin piece, then turning the back side into the inner surface, bending it at the U-shaped groove part, and cutting the outer surface of the corner to provide a chamfered part. Decorative materials were known. 5 However, while the above-mentioned conventional laminated decorative materials are extremely strong, they have the disadvantage of being heavy and difficult to handle.Also, with hollow decorative materials, although the weight is light, reinforcing bars are installed in the hollow parts. It has the disadvantage that it is difficult to firmly mount it, and it is extremely easy to deform.

The present invention was made for the purpose of improving the above-mentioned drawbacks of the conventional decorative materials. Hereinafter, the present invention will be explained in detail based on drawings of embodiments.

15 As shown in FIG. 1, the present invention is constructed by inserting identical resin plates 1 at intervals, placing wood pieces 2 between the resin plates 1, and laminating them in an integrated manner. The resin plate 1 of the laminated wood A is formed as shown in FIG.
Laminated board B is assembled by cutting into small pieces in 20 directions perpendicular to the stacking direction and inserting the same resin pieces 3 at intervals.
Then, as shown in FIG. 3, a decorative sheet 4 such as a wooden veneer, printing paper, or vinyl chloride resin sheet having the same wood grain pattern as the resin piece 3 is applied to the surface of the laminated board B using an adhesive. 25
At the same time, as shown in FIG.
From the back side of the laminated board B, a twin hazel-shaped groove 5 is carved, and then the back side is turned into an inner surface, and the portion of the twin hazel-shaped groove 5 is successively bent to form the inner surface of the corner part 6 as shown at 30 in Fig. 5. After forming grooves 7 in the vertical direction for insertion of reinforcing beams, the outer surface of the corner portion 6 is cut to provide a chamfered portion 8 to form a hollow decorative material C, as shown in FIG.

The hollow decorative material C of the present invention can be used as architectural materials such as pillars and picture frames, but when used in places where external forces are particularly likely to be applied, the hollow decorative material C of the present invention can be Corners 6, 6...The ends of the reinforcing bar 9 are inserted into the grooves 7 formed on the inner surface, and the reinforcing bar 9 is stretched between the grooves 7. This may be used as a solid hollow decorative material D with reinforcing bars that is hard to deform.

Incidentally, the reinforcing bar 9 may be assembled in advance in a cross shape, a Y shape, etc., and may be inserted and fixed into the groove 7 on the inner surface of the corner portion 6 of the hollow decorative material C of the present invention.

According to the method for producing a hollow decorative material of the present invention, it is possible to freely produce a hollow decorative material C having a polygonal shape other than the rectangular shape of the above embodiment. All you have to do is change it.

Incidentally, the groove angle of the twin hazel-shaped grooves 5 when making the rectangular hollow decorative material C is 45°. The present invention is constructed as described above, and the hollow decorative material of the present invention has chamfered portions at the corners, is lightweight, and has the effect of easily inserting and fixing reinforcing bars to maintain firmness. have.
