Abstract

(57) [Summary] [PROBLEMS] To provide a device which is relatively thin, lightweight, tough, and water-resistant, and does not generate toxic gas during combustion. SOLUTION: A tatami floor in which a wood fiber board is interposed between cork boards. A tatami floor in which a plywood and a wood fiber board are laminated and interposed between a cork board and a cork board.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention aims to provide a relatively thin, lightweight, tough, water-resistant tatami floor and tatami mats.

[0002]

[Problem to be solved by the invention]

 Conventionally, as a relatively thin and lightweight tatami floor, a structure in which a foamed synthetic resin plate is interposed between a plywood or a pressure paper plate is known.

[0003] The above-mentioned pressurized paper board has a problem of losing water resistance due to its moisture absorption property, losing elasticity and losing durability when moisture is absorbed.

[0004] Furthermore, while the foamed synthetic resin plate maintains a predetermined thickness and is lightweight, it has problems that it is not only durable but also generates toxic gas by combustion.

[0005]

[Means for Solving the Problems]

 In this invention, since the fiberboard is interposed between the cork boards or the plywood is layered on the fiberboard, it is water-resistant, lightweight and tough, hardly absorbs moisture, and its strength is not changed by drying even when wet with water. .

[0006] That is, the invention of the tatami floor is a tatami floor in which a wood fiber board is interposed between cork boards, and a plywood and a wood fiber board are provided between the cork boards. The tatami floor is characterized by being laminated and interposed. In addition, the invention of the tatami mat is a tatami mat characterized by having a tatami mat on a tatami floor with a wood fiber board interposed between the cork boards, and a corrugated board between the cork boards. This tatami mat is characterized by having a tatami mat on a tatami floor with laminated plywood and wood fiber boards.

The above-mentioned wood fiber board is obtained by press-molding a mixture of wood chips and an adhesive (for example, an inorganic adhesive).

[0008]

[Embodiment of the invention]

 This invention is a tatami floor in which a wood fiber board is interposed between two cork boards, or a tatami floor in which a wood fiber board and a plywood laminate are interposed between two cork boards.

Next, the tatami mat has a tatami mat on the tatami floor.

[0010]

Embodiment 1 An embodiment of the present invention will be described with reference to FIGS. The tatami floor 4 was constructed by interposing a 10 mm thick wood fiber board 3 between the 5 mm thick cork boards 1 and 2, and the tatami mat 5 was attached to the outside of the tatami mat to make the tatami mat 6 of the present invention. .

In the above description, since the cork plates 1 and 2 have elasticity, the feeling transmitted to the human body is the same as that of the straw floor. In addition, since the cork plates 1 and 2 are heat insulating, both heating and cooling are good, resulting in thermal economy. In addition, since the fiberboard 3 is tough, the cork boards 1 and 2 do not have a risk of cracking even in a normal exercise on a tatami mat or a judo, and the durability can be maintained long.

[0012]

Embodiment 2 The embodiment shown in FIGS. 3 and 4 further improves the toughness of the tatami floor. That is, a tatami floor 4 is constructed by interposing a plywood 7 having a thickness of about 3 mm between two cork boards 1 and 2 having a thickness of 5 mm and a wooden fiber board 3 having a thickness of 10 mm. 5, the tatami mat 8 of the present invention was made.

Although the tatami mat 8 of the previous embodiment is lightweight, the toughness is further improved, and there is no possibility that the tatami mat 8 will be excessively deformed even when a bookcase, a chest and other heavy objects are left for a long time.

[0014]

[Effects of the Invention] In the present invention, since a wood fiber board is interposed between cork boards, a tatami floor and a tatami mat having a relatively thin, light weight and excellent water resistance can be obtained. In addition, when plywood is interposed, permanent deformation is small even when a heavy object is placed, which has the effect of enduring long-term support.

In addition, there are various effects such as high water resistance, no reduction in strength even when wet with water, and no risk of producing toxic gas even when burned in a fire.
