[Industrial applications]

 The invention of this application relates to a decorative composite floorboard used for a building floorboard.

[0002]

[Prior art]

 Conventionally, most of the decorative floorboards of this type are floorboards in which a decorative sheet is directly attached to the surface of lauan plywood. However, in recent years, due to the problems of resource depletion in tropical rain forests and environmental destruction, there has been a move to minimize the use of lauan plywood. The inventor of this application used particle board as an alternative material for lauan plywood, and attached a decorative sheet on the surface of the board, followed by shading on the four circumferences, and found that the strength of the female strip was very weak and prone to chipping. I knew there was a flaw. Furthermore, it was found that when grooves were formed on the surface of the obtained decorative floorboard, the grooves reached the particle board and became very unsightly.

[0003]

[Problems to be solved by the device]

 The invention of this application was made in order to solve the above-mentioned drawbacks, and an object thereof is to provide a resource-saving type decorative composite floor board which has sufficient strength even after being sanded.

[0004]

[Means for Solving the Problems]

 The invention of this application is such that a thin plywood, a hardboard or a medium fiberboard having a thickness within half the thickness of the above-mentioned particle board is attached to the surface of a particle board having a thickness of 6 mm or more, and the surface thereof is covered with makeup. A decorative composite floorboard in which a sheet is attached and four rounds of a particle board are subjected to a sanding process will be described in detail below with reference to the drawings.

In FIG. 1, 1 is a particle board having a thickness of 6 mm or more, and a thin plywood having a thickness within half the thickness of the above-mentioned particle board, a hard board or a medium fiber board 2 is attached to the surface thereof. Has been done. The thickness of thin plywood etc. 2 is limited to less than half of the thickness of particle board because particle board 1 is sanded when four rounds of the decorative composite floor board are sanded. In order to prevent the thin plywood or the like 2 attached to the surface of the sheet from being subjected to the grooving and to have the strength of the upper piece 4 constituting the female panel 3 by the thin plywood or the like 2. Is. It should be noted that the lower piece 5 that constitutes the female box 3 is a place where it is hidden after the construction, even if it is a little chipped, so there is no problem. Reference numeral 6 is a male strip, which is fitted with the female strip 3 during construction. It should be noted that the male box 6 is formed into a shape as shown in the figure to prevent the male box 6 from cracking when nailed and fixed to the joist.

Further, the thickness of the particle board 1 is limited to 6 mm or more because a minimum thickness of 6 mm is required for use as a decorative composite floorboard.

Reference numeral 7 denotes a veneer stuck to the surface of the thin plywood 2 or the like, a makeup sheet such as a cosmetic chloride sheet, and a groove 8 reaching the thin plywood 2 or the like is formed on the surface, and the inner surface of the groove 8 is formed. The thin plywood, etc. 2 is cut and exposed, but unlike the particle board, the thin plywood, etc. 2 is not so unsightly, and it is a very clean groove in the case of a hard board or medium fiber board. Is formed.

On the back surface of the particle board 1, paper, vinyl chloride, thin plywood, veneer or the like may be attached or painted. Further, water resistance processing or antiseptic processing may be applied to one or both of the four circumferences and the back surface of the particle board 1.

[0009]

[Effect of the device]

 Since the present invention is constructed as described above, not only can an inexpensive decorative composite floorboard be obtained, but a particle board is used as an alternative material for Lauan plywood, and a sanding process is applied to its four circumferences. Even so, it is possible to obtain a decorative composite floorboard that is sufficiently strong and does not have a chipped surface.
