Description

  The present invention relates to a floor surface structure formed by a plurality of tatami mats having appropriate hardness and softness, and more particularly to a floor surface structure that can be formed in various forms and is easy to use.

Traditionally, in Japanese houses, tatami mats made of tatami mats made of grass and tatami floors made mainly of rice straw have been used as flooring unique to Japan, and are closely related to the Japanese lifestyle. Sitting on the bed and having a meal, or lying on the side and living.
However, in recent years, with the diversification of lifestyles (lifestyles), Western-style rooms have become mainstream in Japanese houses, and the floor surface is increasingly made of wooden flooring (board floor). However, wooden flooring cannot be comfortably relaxed even when sitting directly on the floor or lying down because it is hard and soft and lacks cushioning, unlike tatami mats, even with carpets and other rugs.
Therefore, recently, there is an increasing number of people who have reexamined the texture and lifestyle of traditional Japanese-style housing styles and incorporated Japanese-style tastes into living spaces even in Western style housing styles. For example, a required number of so-called tatami mats are laid on a wooden flooring floor, or a Japanese-style room is formed by laying tatami mats on the floor of a room in a Western-style building. In particular, elderly people prefer Japanese styles, and even in homes where infants are present, the use of tatami mats is increasing because they have moderate hardness and softness and also have soundproofing and sound absorbing effects.

Here, in order to reduce the burden of designing and building during building construction, tatami mats placed on the entire floor of a traditional Japanese room have a certain standard, although the dimensions vary depending on the region, and the aspect ratio is There are two types: 2: 1 rectangular tatami mat size and square half tatami mat size. For example, in a room with four tatami mats, four tatami mat types and one half tatami mat type are laid.
In addition, the tatami mats to be laid on the wooden flooring floor can be arranged according to the room structure, floor plan, and lifestyle, and can be easily laid and removed. There are many thin tatami mats in the market.
In addition, in the tatami mat, coupled with the diversification of tastes, the design that can change the atmosphere as the room's structure, floor plan and lifestyle, and the room's accent and decoration There is a demand for the nature, and even when tatami mats are laid down to form a Japanese-style room, the semi-tatami type tatami mats with different color schemes are alternately laid to create a Japanese modern space like a checkered pattern. Things are gaining popularity in renovations and renovations, including new homes.

However, the semi-tatami type square tatami mats, especially the tatami mats, are lighter and more convenient than those of 1 tatami size. If the four corners of the square tatami are gathered at one place, it cannot be avoided that the corners of the square tatami are gathered. There is a problem that a gap is generated due to misalignment, and dust or dust falls and accumulates in the gap, or it is easy to burn by the gap. Garbage and dust that fall into the gap are difficult to clean. In particular, garbage and dust, such as food residue, become mite foods, and if trash or dust accumulates, there is a risk of mite breeding.
In addition, in a semi-tatami type square tatami mat, if you want to express an intermediate size such as 4 帖 1/2, 6 帖, 8 帖, etc., for example 1.5 帖, 5 帖, etc. There are limited variations in design expression.

  Here, in Patent Document 1, the four corners of the semi-tatami tatami mat, which is half the size of the tatami mat and whose aspect ratio is 1: 1, and the quarter tatami mat, which is half the size of the square tatami mat, do not concentrate on each other. The floor finish structure of Japanese-style rooms arranged in a row is disclosed, and in the drawing, the four corners do not concentrate with each other corresponding to 4 1/2, 6 帖, 8 帖 etc. by the combination of square tatami mat and quarter tatami mat An example of such an arrangement is disclosed.

  Moreover, in patent document 2, the corner | angular part of the flooring adjacent to a horizontal direction is made to correspond, and it prevents it from concentrating four corners by shifting and laying the corner | angular part of the flooring adjacent to the vertical direction. A method for laying flooring is disclosed. In the embodiment, a rectangular flooring having an aspect ratio of 2: 1, that is, a size obtained by further halving a half tatami mat having an aspect ratio of 1: 1 (square), that is, a ¼ size rectangle of 1 tatami size. Combined with a square flooring having a 1: 1 aspect ratio that is halved of this 1/4 size, the corners of the flooring adjacent in the horizontal direction are matched, and adjacent in the vertical direction. The thing which formed the whole shape in the square by shifting and arranging the corner | angular part of the flooring to perform is disclosed.

  Further, in Patent Document 3, a quarter long point from one side of one long side and a quarter from the other side of the other long side of the tatami body in which the ratio of the short side to the long side is 1: 2. A trapezoidal two-part tatami with a base-to-top ratio of 3 to 1 by cutting obliquely between the long points at an angle of 45 degrees, and a tatami body with a ratio of short to long sides of 1 to 2 It is described that when combined, the overall shape can be laid on the floor surface as a triangle, a parallelogram, a V-shape, or the like.

  In addition, in Patent Document 4, a conventional standard tatami mat has a geometric shape such as a square, a rectangle, a triangle, and a round shape in order to reduce weight and size, improve transportability and workability, and facilitate installation. It is described that the divided block tatami mats are combined and laid.

Japanese Patent Laid-Open No. 4-80458 JP 2006-274727 A JP-A-53-49837 JP 2008-163619 A

  However, in Patent Document 1 and Patent Document 2, both are a combination of a square shape with an aspect ratio of 1: 1 and a rectangular shape with an aspect ratio of 2: 1. Is not unified, the overall balance is poor and the appearance and design are inferior. On the other hand, in the case of unifying the rectangular shape with an aspect ratio of 2: 1, it is impossible to arrange 4 corners, 6 inches and 8 inches by avoiding four corners gathering at one corner.

  In addition, in Patent Document 3, the trapezoidal shape can be used to represent an overall shape that cannot be expressed by a combination of a square shape or a rectangular shape as a triangular shape or a pentagonal shape. However, the presence of an acute angle portion makes it easy to whip, so their shape is not necessarily practical. Furthermore, there is not much practical benefit of forming the overall shape in a triangular shape according to the corners of the room, and the actual frequency of use is extremely low. Moreover, when forming in trapezoid shape, since there exists an acute angle part, the process of the edge part is difficult and it is estimated that a process requires a lot of effort.

  Furthermore, Patent Document 4 describes that a block tatami divided into geometric shapes such as a square, a rectangle, a triangle, and a circle is laid and combined. However, there is no disclosure of practical designs of other sizes, and no idea of forming various design surfaces is disclosed.

  Therefore, an object of the present invention is to provide a floor structure that can be formed with a variety of external shapes and internal mosaic patterns, and that is easy to use for laying.

  The floor structure according to claim 1 is a combination of a rectangular small unit tatami mat and a large unit tatami mat having a predetermined size that form a square shape by combining one long side of each other, and the small unit tatami mat and the large unit tatami mat. The unit tatami is composed of one or more of a wood board, a synthetic resin board, a synthetic resin foam, a cork board, and a carbonized board, a cushion material disposed in an upper layer of the core material, and the core material A tatami floor formed by a back material disposed in a lower layer, a tatami surface formed or coated with a synthetic resin covering the tatami floor, and an anti-slip material attached to the back surface of the tatami floor covered with the tatami surface It is configured.

  Here, each of the small unit tatami and the large unit tatami is a rectangular shape having a predetermined size, and forms a square shape when one long side of each other is aligned in parallel. Then, one or more rectangular small unit tatami mats having a predetermined size and one or two or more kinds of small unit tatami mats and one or two or more kinds of the small unit tatami mats and the large unit tatami mat are combined with the floor surface. Form a structure.

As the above-mentioned wood board of the core material that forms the tatami floor that constitutes the small unit tatami and the large unit tatami, insulation board (soft fiber board, IB), semi-rigid fiber board (medium fiber board, semi-hard board, MDF) , Hard fiber board (hard board, HB), particle board and the like.
Examples of the synthetic resin board include plastic cardboard.
Furthermore, examples of the synthetic resin foam include polystyrene foam, polyethylene foam, polypropylene foam, and polyurethane foam.

In addition, examples of the cork board include a raw cork board and a carbonized cork board obtained by carbonizing it by steaming and baking.
As the carbon board, for example, a mixture of carbon powder such as activated carbon or charcoal and a filler and solidified with a binder and formed into a board shape can be used.
A plurality of these may be used in combination, and the arrangement thereof is not particularly limited.
Moreover, a nonwoven fabric etc. are used for the said cushion material which forms a tatami floor. In addition, a nonwoven fabric is the cloth formed by processing a fibrous body mechanically, chemically, and thermally, and joining with the adhesive agent or the fusion | fusion force of fiber itself.
Furthermore, a synthetic resin sheet such as polypropylene is used for the back material.

The tatami mats constituting the small unit tatami and the large unit tatami are, for example, fibrous bodies (linear) obtained by molding (spinning) a synthetic resin such as polyolefin resin into a cylindrical shape (pipe shape) or a column shape. Body), or a fibrous body (linear body) obtained by forming (spinning) Japanese paper into a cylindrical shape (pipe shape) or a column shape, and then coating it with a synthetic resin. It is formed.
Further, the anti-slip material constituting the small unit tatami and the large unit tatami is made of, for example, a synthetic resin foam, felt, rubber or the like. The means for attaching the anti-slip material is not particularly limited, and for example, attachment with a double-sided adhesive tape or the like is possible.

  The floor structure according to claim 2 is a rectangular unit (rectangular) with a ratio of short side to long side of 2: 5, and a rectangular shape with a ratio of short side to long side of 3: 5 ( (Rectangular) large unit tatami combination.

  Here, the small unit tatami with the ratio of the short side to the long side of 2: 5 and the large unit tatami with the ratio of the short side to the long side of 3: 5 are one of the small unit tatami and the large unit tatami. A square shape is formed when the sides are aligned in parallel. In this case, the square tatami mats having an aspect ratio of 1: 1 are divided by a size ratio of 2: 3 on a pair of opposite sides, and a design change of ± 20 mm is allowed.

  For example, a semi-tatami mat (850mm x 1700mm) size (850mm x 1700mm) between the housing estates (public corporation, 56 sq.mm), which is often adopted in recent new houses, especially apartment houses, apartments, condominiums, public housing estates, etc. A small unit tatami having a short side of 310 mm ± 20 mm and a long side of 850 mm, which is divided at a size ratio of 2: 3 on a pair of opposite sides of the square semi-tatami mat, corresponding to the 850 mm) tatami standard, It consists of a combination with a large unit tatami mat with a short side of 540 mm ± 20 mm and a long side of 850 mm.

In addition to the size between housing estates, there are various standards for tatami mats, such as Edo and Kyoto, so it may be adapted to any standard depending on the area used. it can.

It corresponds to the free. Furthermore, when it is within the range of 10 to 18 mm, it can be laid on the floor surface where the opening and closing operation of the closet open / close door and the like is performed in a condominium, an apartment, etc. separated from the floor surface by 20 mm or more.

The floor structure according to claim 6 has a thickness of the core material of the tatami floor constituting the small unit tatami and the large unit tatami within a range of 8 mm to 10 mm, and a thickness of the cushion material of 0.1 to 10 mm. Within the range of 0.3 mm, the thickness of the back material is within the range of 0.2 to 0.4 mm, the thickness of the tatami mat is within the range of 2.5 to 3 mm, and the thickness of the anti-slip material is 2 to 4 mm. Within the range.
The numerical value of the thickness does not require strictness, and a dimensional accuracy error within a range of ± 0.5 mm is allowed.
Further, the same number of small unit tatami mats and large unit tatami mats constituting the floor structure are not necessarily used at the same time, and the combination of the numbers is not particularly limited.

  According to the floor surface structure of the invention of claim 1, the small unit tatami is composed of a combination of a rectangular small unit tatami mat and a large unit tatami mat having a predetermined dimension that form a square shape by combining one long side of each other. The tatami mat and the large unit tatami mat have one or more of a wood board, a synthetic resin board, a synthetic resin foam, a cork board, and a carbonized board as a core material, and further, a cushion material is disposed on the upper layer of the core material. In addition, a tatami floor formed by coating or coating with a synthetic resin is coated on a tatami floor in which a back surface material is disposed and laminated on the lower layer of the core material, and an anti-slip material is attached to the back surface thereof.

  A core material composed of any one or more of a wood board, a synthetic resin board, a synthetic resin foam, a cork board, and a carbonized board, a cushion material disposed in an upper layer of the core material, and disposed in a lower layer of the core material By forming the tatami floor with the back material, the tatami floor can be formed simply by sequentially stacking pre-formed boards, etc., so that the manufacturing work can be simplified, and it is very lightweight and easy to handle. It is easy to cut into a rectangular shape with a predetermined size using the existing equipment. Then, the small unit tatami mat and the large unit are formed by covering the tatami floors cut into the predetermined dimensions in this way, covering the tatami surface formed or coated with synthetic resin, and attaching an anti-slip material to the back surface thereof. The tatami mats are lightweight but secure high strength, have good durability, are low cost, have high dimensional accuracy, and have a certain quality. Furthermore, it is highly moisture-proof and can prevent the growth of mold and mites.

In particular, when the core material of the tatami floor is formed by an insulation board as a wooden board, the antibacterial properties, humidity conditioning, deodorizing properties, heat insulating properties, soundproofing and sound absorbing properties, etc., which are the characteristics of wood are exhibited, and in a humid environment In addition, the growth of mites, molds, etc. is suppressed, and the stable quality is maintained with little corrosion.
Also, when plastic corrugated board as a synthetic resin board is used in addition to the insulation board as the core material, it is lightweight yet secures high strength, has good durability, and further improves buffering, depending on heat and humidity Expansion and warping deformation can also be suppressed.
In addition, the cushioning material provided in the upper layer of the tatami floor provides high cushioning properties, and can be expected to provide soundproofing and sound insulation effects, and can absorb variations in dimensions.
Furthermore, the back surface is reinforced by the back material disposed in the lower layer of the tatami floor, and warpage deformation is further prevented.

  In addition, since the anti-slip material is attached to the back surfaces of the small unit tatami mat and the large unit tatami mat, even when laid on a flooring floor or the like, displacement is prevented. Therefore, it can be kept hygienic by preventing dust and dust from accumulating in the gap caused by the misalignment, and tick breeding, and there is less time to correct the misalignment and there is a risk of falling due to the misalignment. It is also small and improves the usability of laying.

  And, by combining the small unit tatami and the large unit tatami in a rectangular shape with such a configuration, the small unit tatami and the large unit tatami arranged in parallel adjacently in the same longitudinal direction and short direction. Two small unit tatami mats and / or large unit tatami mats are arbitrarily selected, and one small unit tatami mat or a large unit tatami mat arbitrarily selected from a small unit tatami mat and a large unit tatami mat are arranged in parallel. The two small unit tatami mats and / or the large unit tatami mats are adjacent to each other at right angles with the longitudinal direction and the short direction reversed, and the adjacent sides of the three small unit tatami mats and large unit tatami mats are adjacent to each other. Arranged so as to form a T-shape, that is, another small unit tatami mat with respect to the longitudinal direction of two small unit tatami mats and / or large unit tatami mats arranged in the same direction, or Daiyu Arrangement so that the short direction of the tatami mat is the same direction (in other words, in the short direction of two small unit tatami mats and / or large unit tatami mats arranged in the same direction, The small unit tatami or the large unit tatami are arranged so that the longitudinal direction of the small unit tatami is the same direction), and the four corners of the small unit tatami and large unit tatami are not collected in one place, but the whole is square. Laying corresponding to 2, 4, and 8, etc. is possible. Furthermore, the same can be achieved with a 6-inch or the like having a rectangular shape as a whole.

  Therefore, even when laid as a tatami mat on a flooring floor in a living room, etc., it is possible to prevent misalignment that tends to occur when four corners of the tatami are concentrated in one place. The arrangement makes it difficult for gaps to form between each other, preventing dust and dirt from accumulating in the gaps and making it easier for mites to propagate and maintaining hygiene. There are few, and the danger of the fall by slippage is also small, and it becomes easy to use for laying.

According to the floor structure of the invention of claim 1, the small unit tatami and the large unit tatami are rectangular and have the same directionality such as the longitudinal direction and the short direction, so that the directionality is the same. Designs such as regular, irregular (random), and symmetrical designs can be produced by arranging and combining the direction and direction, and small unit tatami mats and large unit tatami mats with different patterns, colors, materials, etc. When combined, the variation of design expression is further increased, and various external shapes and internal mosaic patterns can be expressed.
In addition, because it is very lightweight and easy to carry and lay, it is easy to change or replace the number and arrangement of laying even when laying on a flooring floor in a living room, etc. It is easy to change the design surface.

At this time, since the small unit tatami and the large unit tatami are rectangular, there is a sense of unity overall, and the visual balance is excellent, and various external shapes and internal mosaic patterns can be formed with good appearance. Of course, since the square shape is formed by combining one long side of the large unit tatami mat and the small unit tatami mat, it is also possible to represent a square design surface.
Therefore, it is possible to respond to the user's lifestyle, taste, personality, room usage, floor plan / structure, laying location, etc., and it is excellent in usability.

Intermediate sizes between 5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, etc. can be expressed, and variations of expressible sizes increase. Therefore, it is possible to cope with the needs of the user. In addition, intermediate sizes between 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, etc., and conventional tatami mat standards such as 4.5 mm, 6 mm, 8 mm, etc. Even when it corresponds to other than 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, etc., the overall shape is an L-shaped array and the overall aspect ratio is large and the overall shape is an elongated rectangular shape. Without being limited to the arrangement, the overall aspect ratio is small and the overall shape is close to a square, so that it is possible to express the outer shape in a visually balanced manner. Of course, also at this time, by arranging the three small unit tatami mats and large unit tatami mats adjacent to each other so as to form a T shape or an inverted T shape, the corners of the small unit tatami mats and the large unit tatami mats are arranged. Arrangements are possible that do not allow four of the parts to be collected in one place.

  Here, the numerical values of 2: 5 and 3: 5 are the results of the inventors' diligent experiment research, and the rectangular small unit tatami mat and the short side having a ratio of the short side to the long side of 2: 5.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The floor surface structure 1 of the present embodiment has one or more rectangular small unit tatami mats S having a ratio of short side to long side of 2: 5 shown in FIG. 1 and a ratio of short side to long side. A rectangular large unit tatami mat M having a ratio of 3: 5 consists of a combination of two small unit tatami mats S and one or more large unit tatami mats M. The small unit tatami S and the large unit tatami M are divided by a size ratio of 2: 3 on a pair of opposite sides of a square tatami mat of a predetermined standard half tatami mat with an aspect ratio of 1: 1. A square shape is formed by combining two long sides.

Here, the structure of the small unit tatami mat S and the large unit tatami mat M constituting the floor surface structure 1 of the present embodiment will be described with reference to FIG.
Both the small unit tatami mat S and the large unit tatami mat M of this embodiment are composed of a tatami floor 10 and a tatami table 20 covering the tatami floor 10 like a general tatami mat.
The tatami floor 10 forms the main body of the small unit tatami S and the large unit tatami M. For example, the tatami floor 10 has a predetermined thickness with a wood board, a synthetic resin foam, a synthetic resin board, a rubber board, a grass, etc. as a core material. It is formed into a mat shape having moderate rigidity and softness.

  As a core material of the tatami floor 10, for example, a wooden board such as an insulation board, a synthetic resin foam (foamed resin foam) such as polystyrene foam (foamed polystyrene), a synthetic resin board such as plastic corrugated cardboard, rubber board, cork ( Carbonized cork) Compressed flooring materials (chemical floors, synthetic floors) that have been combined with any one or more of board, carbon board, etc. and traditionally used as tatami floors It is possible to make a cocoon floor formed by the above method, or a cocoon sand floor in which a synthetic resin foam, a wooden board, a cork, a carbon board or the like is sandwiched between cocoons.

  When building materials (chemical) floors such as wooden boards, synthetic resin foam, synthetic resin boards, rubber boards, cork boards, carbon boards, etc. are used as the core material of the tatami floor 10, insect control (anti-mite) and mold prevention In addition, the small unit tatami mat S and the large unit tatami mat M can be obtained with a high dimensional accuracy, a high dimensional accuracy, and an inexpensive and light weight. When dredging material is used, moisture-adjusting and purifying effects due to the moisture absorption / release characteristics of dredging can be obtained, and elasticity, shock absorption, durability, heat insulation / heat insulation, sound insulation / sound absorption are high and soft. The small unit tatami S and the large unit tatami M are recyclable.

In addition, as a wood board, wood fiber boards, such as an insulation board (soft fiber board, IB), a semi-hard fiber board (medium fiber board, a semi-hard board, MDF), a hard fiber board (hard board, HB), A particle board, a veneer board, etc. are mentioned. When wood boards are used, the characteristics of wood can be obtained. In particular, insulation boards are highly durable and humidity-controllable and can be recycled, and they can be warped due to changes in ambient environmental conditions (temperature differences, humidity differences). Since there are few dimensional shape changes, such as expansion and contraction, it is suitable as a core material of the tatami floor 10.
Examples of the synthetic resin foam include polystyrene foam, polyethylene foam, polypropylene foam, and polyurethane foam. The synthetic resin foam has a heat insulating effect, and since it is inorganic, moisture hardly spreads inside, and mites and molds hardly propagate. In particular, polystyrene foam is suitable as a core material for the tatami floor 10 because it has moderate rigidity, high heat insulating properties and buffering properties, is extremely lightweight, and does not transmit moisture.
Examples of the synthetic resin board include plastic corrugated cardboard, plastic board, foamed plastic board, and the like. When the synthetic resin board is used, high strength is obtained while being lightweight.

Examples of the cork board include a raw cork board and a carbonized cork board obtained by steaming and baking it. By using a cork board having hygroscopicity and adsorptivity, it is possible to obtain a dehumidifying effect and a deodorizing effect, thereby suppressing the growth of mold, mites, etc., and purifying unpleasant odors. Moreover, the cork board has moderate elasticity, so that the cushioning property of the tatami floor 10 can be made high.
As the carbon board, for example, a board formed by solidifying a mixture of carbon powder such as activated carbon or charcoal and a filler with a binder can be used. By using a carbon board having humidity control and adsorptive properties, it is possible to obtain a dehumidifying effect and a deodorizing effect, thereby suppressing the growth of mold and the like, and purifying unpleasant odors. In addition, since the carbon board has good heat insulation and heat retention, the indoor temperature can be kept stable, and the operating energy of the air conditioner can be saved.

  Furthermore, as a constituent member constituting the tatami floor 10 in addition to the core material, a protective material (for example, non-woven fabric, paper, cardboard, etc.) for preventing fuzzing and scattering of a wooden fiberboard, etc., pressure resistance and strength Reinforcing material for reinforcing (for example, non-woven fabric, paper, cardboard, particle board, etc.), cushioning material for improving cushioning properties (for example, non-woven fabric, etc.), back surface material for reinforcing the back surface of the tatami floor 10 (for example, , Vinyl sheets, etc.) can be used in appropriate combinations. Further, a metal plate such as an aluminum plate, a glass mat-like sheet, or the like can be used as a constituent member of the tatami floor 10. In particular, when the small unit tatami S and the large unit tatami M are so-called thin tatami mats with a thickness of 30 mm or less, floor heating is installed by sandwiching the core material with a metal plate such as an aluminum plate or a glass mat-like sheet. Even when laid on the floor, a small unit tatami mat S and a large unit tatami mat M with little deformation such as warpage and high thermal conductivity can be obtained.

In addition, a porous material such as activated carbon or zeolite is mixed in the core material or constituent member constituting the tatami floor 10 or a sheet formed using a porous material such as activated carbon or zeolite is interposed in the tatami floor 10. Thus, the small unit tatami mat S and the large unit tatami mat M having deodorizing properties and humidity control properties using activated carbon, zeolite, or the like can be used.
Furthermore, the catechins (mainly tannin) extracted from green tea etc. are sprayed on the tatami floor 10 with a sheet-like catechin sheet which is dried and sprayed, and a small unit having antibacterial and deodorizing properties by catechins Tatami S and large unit Tatami M can be used. In addition, the addition of antibacterial agents and antiseptics such as allyl isothiocyanate, benzyl isothiocyanate, citral, citronellol, hinokitiol, perilaldehyde, and α-limonene can also produce the effect of suppressing the reproduction of mites and molds.

In addition, the core material and the constituent members constituting the tatami floor 10 include a far-infrared radiator, such as a far-infrared ceramic (alumina, silica, sodium oxide, potassium oxide, iron oxide, titanium oxide, fluorine oxide, etc.), tourmaline ore, Mixing quartz ore, biotite, carbon-based materials (charcoal, activated carbon, Bincho charcoal), or interposing a far-infrared radiation sheet formed with a far-infrared radiator on the tatami floor 10 to provide a far-infrared effect The small unit tatami S and the large unit tatami M may be used. According to the small unit tatami mat S and the large unit tatami mat M formed using a far-infrared radiator, for example, in a kitchen or the like where the installation location and frequency of use are limited and immediate warming is important even when installing a heater. By simply laying on the floor, it is possible to obtain a heating / warming effect by far-infrared rays, which can be suitably used. Moreover, when it lays on the floor surface which installed floor heating, a heating effect can be heightened more.
In addition, for example, by introducing a boric acid sheet in which boric acid dissolved in a liquid such as water is infused into a nonwoven fabric or the like by spraying or the like, the occurrence and reproduction of mites, cockroaches, white ants, etc. are suppressed, and the antibacterial effect is exerted. The small unit tatami S and the large unit tatami M may be used.

The tatami floor 20 covering the tatami floor 10 is formed by, for example, forming a woven fabric obtained by weaving a traditional non-traditional grass with hemp yarn or cotton yarn, or a cylindrical fiber yarn made of wood fiber paper or bamboo. What weaved fiber, what weaved with fiber-making yarn and coated with synthetic resin, what weaved fibrous body made of synthetic resin, what we knitted pattern on resin sheet such as vinyl chloride And the like. In the case of a woven fabric, the weaving method is not particularly limited, and examples thereof include plain weave, twill weave, scale, various items, longan, jacquard weave, and the like.
The thickness of the tatami surface 20 is usually set in the range of 0.5 to 4 mm, more preferably in the range of 1 to 3 mm, from the viewpoint of mechanical properties, manufacturing cost, and the like.

  In the small unit tatami mat S and the large unit tatami mat M of the present embodiment, the tatami table 20 is directly attached to the tatami floor 10 by sewing, tucker or the like so as to cover and wrap the surface of the tatami floor 10. Specifically, the tatami surface 20 covers the entire upper surface (front surface) of the tatami floor 10, further covers the entire side surface, and wraps around the side surface to the lower surface (back surface). A part is attached so that it may reach even the back surface of the tatami floor 10 (refer FIG. 2). In this way, by attaching the tatami surface 20 to the tatami floor 10 so as to cover the upper surface and side surfaces of the tatami floor 10, even when laid on a flooring floor or the like as a tatami mat, the side edges of the tatami floor 10 are cut. The structure is exposed and looks good without deteriorating the appearance. Further, there is no possibility that the tatami surface 20 is peeled off or the tatami floor 10 is damaged by use.

However, when the small unit tatami S and the large unit tatami M are provided with tatami edges as will be described later, or when the small unit tatami S and the large unit tatami M are spread over the entire floor of the Japanese-style room, the sides do not become straw. The tatami surface 20 may be attached to the tatami floor 10 from the upper surface to a part of the side surface, that is, the end of the tatami surface 20 is arranged on the side surface.
In addition, as a means to attach the tatami surface 20 with respect to the tatami floor 10, it can also attach using a tucker, for example, and you may sew with a tatami thread etc.

  At this time, in order to enhance the adhesion between the tatami surface 20 and the tatami floor 10 and to ensure flatness, it is preferable to join the two together with an adhesive such as a solvent type, an aqueous emulsion type or a hot melt type, or a double-sided tape. At this time, the tatami mat 20 and the tatami floor 10 are bonded to each other on the entire back surface of the upper surface of the tatami mat 20 and the entire upper surface of the tatami floor 10, and the side surface of the tatami floor 10 and the tatami mat 20 are not bonded. Absorbing errors and having a margin on the side face makes it difficult for gaps to occur even when the small tatami mats S and large unit tatami mats are slightly displaced from each other.

  The structure of the small unit tatami S and the large unit tatami M is a place where the small unit tatami S and the large unit tatami M are laid (for example, a restaurant that requires cleanliness, ease of cleaning, etc.) Or is it an office with a heavy load on the tatami mat, or a large plaza of an inn or the like where the load on the tatami mat is large and requires frequent replacement), and the design / floor base of the laying place Depending on the material type (for example, whether it is laid on concrete or wooden flow long floor), the climate, humidity, etc. of the laying site, the selection, combination and arrangement of the materials, the thickness of the component, etc. Setting is possible.

  Moreover, the thickness (thickness dimension) of the small unit tatami mat S and the large unit tatami mat M is usually set within a range of 10 to 60 mm. In particular, by setting the thickness (thickness dimension) of the small unit tatami S and the large unit tatami M to 30 mm or less, the thickness is thin, so that the demand for barrier-free with few steps can be met, and floor heating is installed. Even when laid on the floor surface, the heat of the floor heating can be efficiently transmitted to the tatami mat 20. Furthermore, when it is within the range of 10 to 18 mm, it becomes possible to lay on the floor surface where the opening and closing operation of the closet doors that are installed at 20 mm or more apart from the floor surface in condominiums, apartments, etc. is performed, and the degree of freedom of installation Will increase.

The small unit tatami mat S and the large unit tatami mat M of the above embodiment are so-called “no border” or “shaved tatami mat” in which the tatami mat 20 is attached to the tatami floor 10 directly by sewing or tucker. Yes, when laid, the outline is not emphasized, and it has the effect of showing it simply and widely.
However, when practicing the present invention, a tatami edge made of a fabric such as silk, hemp, cotton, or synthetic fiber is provided on a specific facing edge or all sides of the tatami surface 20, and the tatami edge is sewn on the side surface of the tatami floor 10. By doing so, it is also possible to attach the tatami surface 20 to the tatami floor 10. In this case, a headboard may be inserted between the tatami surface 20 and the tatami floor 10 as a reinforcing material for keeping the corners of the tatami end (kamachi portion) or the like correctly. In general, an edge base is used as a core material for the tatami rim.

Here, when the small unit tatami mat S and the large unit tatami mat M of the present embodiment are placed on a flooring floor such as a living room, the tatami mat 10 is formed on a tatami mat 10 formed by stacking core materials and the like. An anti-slip material 30 having an anti-slip function is further attached to the back surface of the tatami structure to which 20 is attached.
Examples of the anti-slip material 30 include polyolefins such as vinyl acetate copolymer, ethylene vinyl acetate copolymer, ethylene ethyl acrylate copolymer, ethylene methyl acrylate copolymer, ethylene propylene copolymer, polyurethane, silicone, and the like. , Synthetic resin such as polyvinyl chloride resin, and synthetic rubber and natural rubber sheets such as polyisopropylene, polybutadiene, butadiene-styrene copolymer, acrylonitrile-butadiene copolymer (nonwoven fabric, felt-like ones) Including) is used. These are selected in consideration of the material of the underfloor material for laying the small unit tatami S and the large unit tatami M, and a material having a large friction coefficient with respect to the underfloor material is selected. In particular, in the case of polyolefin resin, it is less harmful and excellent in recyclability. In order to reduce the coefficient of friction with the floor base material, the back surface serving as the installation surface on the floor base material may have an uneven shape. Further, when the anti-slip material 30 has a foam structure made of a synthetic resin foam or has elasticity such as rubber, the cushioning property (flexibility, shock absorption) becomes high, and the small unit tatami mat S and the large unit mat S The warp deformation of the unit mat M can be prevented.

Next, the manufacturing procedure of the small unit tatami mat S and the large unit tatami mat M configured as described above will be described. Since the small unit tatami S and the large unit tatami M have the same configuration and the same manufacturing procedure except for their sizes, they will be described without distinguishing between them.
First, the core material and constituent members of the tatami floor 10 are appropriately laminated, and in the laminated state, for example, sewing with tatami yarn (hemp yarn, etc.) using a tatami sewing machine or the like along the longitudinal direction is performed and tightened. Alternatively, the tatami floor 100 is formed by adhering to each other with an adhesive or a double-sided adhesive tape. Examples of the method for applying the adhesive include application with a brush and application by spraying using a spray gun. Moreover, the material of the tatami floor 10 piled up before joining is compressed with a roll as needed.

Subsequently, the tatami floor 10 is cut into a predetermined width and length.
Specifically, it is a tatami floor 10 that forms a small unit tatami S by cutting it into a rectangular shape with a ratio of short side to long side of 2: 5, and a ratio of short side to long side of 3: 5. It is set as the tatami floor 10 which comprises the large unit tatami mat M by cut | disconnecting into the rectangular shape to do.
For example, the small unit tatami S can be removed from the 2/5 size side by cutting at a size ratio of 2: 3 on a pair of opposing sides of the tatami floor 10 sized to correspond to a half tatami mat that is half the size of a tatami mat. The tatami floor 10 has a ratio of the short side to the long side of 2: 5. The tatami floor has a ratio of the short side to the long side of 3: 5 on the 3/5 size side. 10 can also be obtained.
In particular, in cutting with a ratio of short side to long side of 2: 5 and 3: 5, cutting with high dimensional accuracy is possible using existing equipment in tatami mat manufacturing regardless of the material and strength of the tatami floor 10. It is possible to obtain a constant quality tatami floor 10 which is low in cost and easy to process.

Next, a fibrous body such as synthetic resin or paper or weed is formed, and the tatami floor 10 cut to the predetermined size is placed on the back surface of the tatami table 200 cut to a predetermined size. The tatami floor 20 is attached to the tatami floor 10 by folding back the tatami floor 10 from the side surface to the back surface and performing tackering or sewing along the end.
In the present embodiment, the tatami surface 20 is cut to a size larger than the area that can cover the entire upper surface and side surfaces of the tatami floor 10 so that the end of the tatami surface 20 that covers the tatami floor 10 can be folded back. Is used.

Moreover, when attaching the tatami surface 20 to the tatami floor 10, the adhesiveness with the tatami floor 10 can be improved by joining the tatami surface 20 to the upper surface of the tatami floor 10 using an adhesive or a double-sided tape. it can.
Further, the tatami surface 20 is bent while being pressed along the side (edge) of the tatami floor 10 as necessary, and the back surface of the tatami 10 is pressed while being pressed toward the center. By performing such a press process, the adhesion between the tatami floor 10 and the tatami surface 20 is improved, and the surface of the tatami surface 20 is free from unevenness by eliminating creases and weaving on the surface of the tatami surface. Can be improved. In addition, you may press using a hot platen.
Further, for example, by inserting the tatami floor 20 on the tatami floor 10 in a rectangular formwork of a predetermined size corresponding to the finished dimensions and extruding it with a predetermined pressure, the adhesion between the tatami floor 10 and the tatami surface 20 is achieved. The small unit tatami mat S and the large unit tatami mat M can be obtained with a high dimensional accuracy, a good contour and good appearance.

  Here, in the case where the small unit tatami S and the large unit tatami M are attached so as to cover the upper surface and side surfaces of the tatami floor 10 entirely without providing tatami edges and to wrap around from the side surface to the back surface, Overlapping portions (overlapping of the tatami mats 20) occur at the ends of adjacent sides of the tatami mat 20, that is, the corners of the four corners reaching the side surfaces and the back surface of the tatami floor 10.

  Therefore, when the tatami mat 20 is attached to the tatami floor 10 with the tatami mat 20 overlapping at the four corners of the tatami floor 10, the small unit tatami S and the large unit tatami M are formed. A gap is formed between the other portion and the floor base material, and the lift is generated, so that when stepping on the small unit tatami S and the large unit tatami M, the cushioning property is good and the tires are not easily fatigued. Further, a gap is generated between the floor base material and air permeability is improved, and mite and mold growth can be suppressed.

However, on the other hand, the overlap of the tatami surface 20 causes a large amount of subsidence when stepped on due to a gap generated between the floor base material and may cause a sense of incongruity. Therefore, it is possible to cut and process the overlapping portion.
At this time, in order to prevent the cut portion from being unraveled and peeled off, an adhesive tape is applied to the cut portion, or a hot melt adhesive such as wax (thermoplastic adhesive that is applied in a molten state and solidified by cooling to join) It is possible to improve the appearance and appearance by solidifying with an agent, and it is difficult to create a gap between the corners and sides of adjacent tatami mats when laid, and has high adhesion This prevents dust and dirt from entering the gap. In particular, hot melt adhesives such as waxes and other olefins are inexpensive and are flexible because they have high adhesive strength and are free from harmful substances such as formaldehyde and organic solvents, and are therefore suitable for the global environment. However, a polyamide-based or ester-based hot-melt adhesive may be used.
For example, when the tatami surface 10 is formed by weaving a fibrous body spun with a heat-weldable polyester resin or the like, the fibrous body at the cut portion is heated by heating means such as an iron or a soldering iron. It can be integrated by cutting and further heat-sealing, and a high effect of preventing breakage of the cutting site can be obtained.

  Further, the anti-slip material 30 is joined to the back surface of the tatami structure with the tatami surface 20 attached to the tatami floor 10 in this way by using an adhesive or a double-sided tape, so that even when laid on a flooring floor or the like, there is no deviation. Can be prevented.

  Thus, the small unit tatami mat S and the large unit tatami mat M which comprise the floor surface structure 1 of embodiment of this invention are manufactured.

Hereinafter, the floor structure 1 according to the embodiment of the present invention will be specifically described with reference to examples.
The floor structure 1 of the present embodiment according to the present embodiment is often used in recent new houses constructed by house makers, especially apartment buildings, apartments, condominiums, public housing complexes, etc. and high-rise houses. As shown in FIG. 1, it is divided by a size ratio of 2: 3 between a pair of opposing sides of a square tatami mat (850 mm x 850 mm) of a semi-tatami size (850 mm x 1700 mm) between existing housing estates (public corporation, fifty-six). In addition, the ratio of the short side to the long side is set to 2: 5 (short side; 340 ± 20 mm) × (long side; 850 mm), one or more rectangular small unit tatami mats S, the short side and the long side A short side with a ratio of 3: 5; 510 ± 20 mm × long side; 850 mm large unit tatami M is composed of a combination of two small unit tatami mats S and one or two or more large unit tatami mats M (See FIG. 1).

  And as shown in FIG. 2, as for the small unit tatami mat S and the large unit tatami mat M which concern on a present Example, the tatami floor 10 was covered with the tatami surface 20, and also the anti-slip | skid material 30 was attached to those back surfaces. It has a configuration.

  Here, the tatami floor 10 constituting the small unit tatami mat S and the large unit tatami mat M of this embodiment includes an insulation board (tatami board) 11 and a plastic cardboard (pradan) 12 as a core material, and a cushion material (buffer material). ) 13 and the back material 14 (see FIG. 2).

  The insulation board 11 is a wood fiber board obtained by pressing (compressing) plant fibers obtained from wood chips or the like into a board shape. For example, timber such as cedar, cypress, hiba and pine, or hardwood such as chestnut and oak is crushed into chips and then defibrated to starch (wood fibers, bark fibers). For example, a plate formed by compression-molding a binder mainly composed of the like and the like and formed into a plate shape is used. In particular, the wood fiber is solidified with a binder mainly composed of starch and the like to form the insulation board 11 only from natural materials without containing volatile substances harmful to the human body, such as formaldehyde, which causes sick house syndrome. Therefore, it will be safe for the human body and the environment without diffusing volatile substances such as formaldehyde, and provide a safe and comfortable indoor environment for elderly people who prefer Japanese-style rooms and infants who should avoid inhaling harmful substances. Can do. Moreover, the pollutant of the indoor air in which the small unit tatami mat S and the large unit tatami mat M were laid according to the wood characteristic of the insulation board 11 can be adsorbed and purified. Furthermore, by using the thinned wood and the end material generated at the time of thinning to the wood forming the insulation board 11, it is possible to contribute to effective utilization of wood resources and environmental conservation. Note that, for example, a wooden board such as a particle board may be used as a reinforcing material in the upper layer or the lower layer of the insulation board 11.

  The plastic corrugated cardboard 12 is a hollow plastic sheet material formed by attaching a plastic liner to one or both sides of a plastic core formed into a wave shape. Examples of the material include polystyrene, polyethylene, polypropylene, phenol, urethane, and vinyl chloride resins. From the viewpoint of moldability, recyclability, dimensional stability against waste heat, Polyethylene and polypropylene resins are preferred.

Furthermore, the cushion material 13 is disposed on the uppermost layer portion of the tatami floor 10 in order to reinforce the cushioning property. In this embodiment, a nonwoven fabric such as polyethylene and polyethylene terephthalate was used.
In the case of carrying out the present invention, as the cushioning material 13, in addition to the nonwoven fabric, foams such as urethane and plastic, MF sheets (paper fibers mixed with inorganic materials such as gypsum, etc.), etc. It is also possible to use it. In particular, by using a porous material such as a nonwoven fabric or a foam, it is air permeable and it is difficult for moisture to accumulate, so that mites and molds can be prevented from breeding.

In addition, the back surface material 14 is for reinforcing the back surface of the tatami floor 10, and for example, a synthetic resin sheet such as polypropylene or polyvinyl chloride is used.
In carrying out the present invention, the synthetic resin sheet may be a moisture-proof sheet, may be reinforced with a woven cloth such as linen, or may be carbon powder such as activated carbon or charcoal. It is also possible to use a carbon sheet or a strong nonwoven fabric. Also, it may be Como knitted with conventional rice straw.

In this embodiment, the plastic cardboard 12 is disposed on the lower side, the insulation board 11 is laminated on the upper side, and the cushion material 13 is disposed on the upper layer of the core material. The tatami floor 10 was formed by sewing with tatami yarn or adhering to each other with an adhesive, double-sided adhesive tape or the like in a laminated state in which the back material 14 was disposed in the lower layer of the material.
That is, the tatami floor 10 that constitutes the small unit tatami mat S and the large unit tatami mat M according to the present embodiment has a back surface material 14, a plastic cardboard 12, an insulation board 11, and a cushion material 13 in this order from the bottom to the top. It is formed as a laminated structure that is laminated and fastened with tatami yarn, or bonded together.

  Thus, in the small unit tatami mat S and the large unit tatami mat M of the present embodiment formed from the tatami floor 10 composed of the insulation board 11, the plastic corrugated cardboard 12, the cushion material 13 and the back surface material 14, it is extremely lightweight, Cutting workability and handling are good, shape stability is excellent, cutting with high dimensional accuracy can be easily performed, and joining can be easily performed using a tucker or the like. In addition, when a suitable thermal conductivity is obtained and laid on a flooring floor, etc., the room temperature can be kept stable, increasing the thermal efficiency of the heater used for indoor temperature control and reducing operating energy. Expected to be effective.

  In particular, by using the insulation board 11 made of wood fiber as the core material of the tatami floor 10, the antibacterial properties, moisture conditioning properties, deodorizing properties, heat insulating properties, sound absorbing properties, etc., which are the characteristics of wood, are exhibited. Even when used in a hot and humid environment in Japan, it is resistant to corrosion and maintains stable quality. That is, the antibacterial property of the insulation board 111 suppresses the growth of ticks and molds, and the humidity control effect of the insulation board 11 can also exhibit the anti-mite / mold-proof effect by keeping the indoor humidity constant. Furthermore, since the insulation board 110 also has deodorizing properties, heat insulating properties, and sound absorbing properties, it is possible to create an environment in which a resident can spend comfortably in the room where the small unit tatami mat S and the large unit tatami mat M are laid. Moreover, it can be recycled.

  Moreover, in addition to the insulation board 11 as the core material of the tatami floor 10, the use of plastic corrugated cardboard 12 ensures high strength while maintaining a light weight and good durability, and further improves buffering properties. Expansion and deformation due to heat and humidity can be suppressed.

  Further, the cushioning material 13 disposed on the insulation board 11 as the core material has a high cushioning property and the touch is also improved. Further, the cushion material 13 is disposed in the uppermost layer portion of the tatami floor 10 covered with the tatami surface 20, that is, the cushion material 13 is disposed between the insulation board 11 as the core material of the tatami floor 10 and the tatami surface 20. As a result, the friction between the tatami mat 20 and the insulation board 11 can be reduced, and the tatami mat 20 can be prevented from being worn out. Thereby, it is prevented that the surface of the tatami mat 20 is uneven due to fraying due to use. Further, the cushion material 13 can absorb variations in the dimensions of the constituent members constituting the tatami floor 10 other than the cushion material 13. Therefore, the shape stability of the tatami floor 10 can be ensured. Furthermore, the cushioning material 13 can absorb sound and vibration, and can be expected to have a soundproofing and soundproofing effect. In particular, the cushioning material 13 formed from a nonwoven fabric has excellent air permeability and flexibility (cushioning property), and has high air permeability. Can prevent mites and molds from breeding.

  In addition, the back surface of the tatami floor 10 is reinforced by the back sheet 14 disposed in the lower layer of the tatami floor 10, and warpage deformation is also prevented by the back sheet 14.

  Further, the tatami surface 20 of the present example covering the tatami floor 10 is a fiber obtained by molding (spinning) a synthetic resin such as a polyolefin resin excellent in heat resistance and strength into a cylindrical shape (pipe shape) or a column shape. Woven knitted bodies (linear bodies) or fibrous bodies (linear bodies) obtained by molding (spinning) Japanese paper into cylinders (pipes) or columns, etc. It is formed by coating. In particular, a fibrous body (linear body) obtained by mixing and spinning a synthetic resin or Japanese paper with a coloring agent such as a dye or a pigment is woven together in combination with a plurality of different colors, or a single fibrous body is formed. In the tatami mat table 20 obtained by dyeing in multiple colors and weaving, a complicated color pattern can be formed on the design surface. Also, if calcium carbonate, etc. with high hygroscopicity is mixed in the fibrous body, stickiness etc. can be suppressed, a touch close to natural grass can be obtained, durability is excellent, and static electricity is hardly generated It becomes.

  In the case of carrying out the present invention, the method of molding the synthetic resin and Japanese paper constituting the tatami table 20 is not particularly limited, and the type of the synthetic resin is not limited to polyolefin resins such as polyethylene and polypropylene. Polyamide resins, polyester resins, acrylic resins and the like can be used. However, from the viewpoints of strength such as abrasion resistance, durability, heat resistance, workability, cost, etc., polyolefin resins and polyester resins having heat welding properties are preferred.

  Thus, in this example, the tatami table 20 is formed of a synthetic resin or coated, so that the strength such as wear resistance is high, and discoloration (fading) hardly occurs and the durability is high. Products of uniform quality can be industrially mass-produced. In addition, it has low water absorption and moisture absorption, high insect repellent (anti-tick) and fungicide, discoloration due to cigarette scorch, etc., and can be easily cleaned with water, etc., and easy to clean and clean. .

  And in the small unit tatami mat S and the large unit tatami mat M of the present embodiment, the tatami floor 10 formed by laminating the cushion material 13, the insulation board 11, the plastic corrugated cardboard 12, and the back surface material 14 made of a nonwoven fabric in this way. The back surface of the tatami structure formed by attaching the tatami surface 20 formed or coated with a synthetic resin, and further comprising a synthetic resin foam having irregularities on the back surface as an installation surface to the floor base material as the anti-slip material 30 An anti-slip sheet is attached (see FIG. 2). Even if the small unit tatami mat S and the large unit tatami mat M are thin and light, the slip preventive material 30 prevents a shift that moves with a slight external force when laid on a flooring floor. Improve the risk of falling over due to slippage. Furthermore, since the anti-slip material 30 is made of a synthetic resin foam, it has a cushioning property, and even when it falls, the impact can be absorbed by the cushioning property, so that safety is high. Further, the anti-slip material 30 is made of a synthetic resin foam, so that warp deformation can also be prevented.

Here, in the small unit tatami mat S and the large unit tatami mat M of the present embodiment, the thickness of the tatami mat 10 is 3 mm, the thickness of the tatami floor 10 is 9 mm, specifically the thickness of the cushion material 13 is 0.2 mm, The thickness of the insulation board 11 was 6 mm, the thickness of the plastic corrugated cardboard 12 was 2.5 mm, the thickness of the back material 14 was 0.3 mm, and the thickness of the anti-slip material 30 was 3 mm, for a total thickness of 15 mm.
By reducing the thickness dimension in this way, even when the small unit tatami mat S and the large unit tatami mat M are laid on a flooring floor such as a living room, there are few steps, and it is possible to effectively prevent falls caused by rolling or the like. Moreover, even when it is laid on the floor surface on which floor heating is installed, the heat conductivity is good and the heat of floor heating can be transferred to the tatami surface 10 and can be used suitably for floor heating. Furthermore, as shown in FIG. 8, it becomes possible to lay on floors such as flooring where opening and closing operations such as the open / close door 32 of the western closet installed in apartments, apartments, etc. are separated from the floor by 20 mm or more, The degree of freedom of installation is high. In addition, the code | symbol 31 of FIG. 8 is a wall surface.
The total thickness of the insulation board 11 and the plastic cardboard 12 constituting the core material of the tatami floor 10 is within the range of 8 mm to 10 mm, and the thickness of the cushion material 13 is within the range of 0.1 to 0.3 mm. The thickness of the back material 14 is in the range of 0.2 to 0.4 mm, the thickness of the tatami mat 20 is in the range of 2.5 to 3 mm, and the thickness of the anti-slip material 30 is in the range of 2 to 4 mm. Even if it is thin, it has moderate hardness and softness, and is easy to relax and comfortable when sitting or lying down.

Next, the manufacturing procedure of the small unit tatami mat S and the large unit tatami mat M of the present embodiment having such a configuration will be described.
In this embodiment, the back surface material 14, the plastic corrugated cardboard 12 (core material), the insulation board 11 (core material), and the cushion material 13 are arranged and stacked in order from the bottom in the longitudinal direction. The tatami floor 10 was formed by sewing with a tatami thread using a sewing machine or the like, or by adhering them together with a double-sided adhesive tape or the like.

Subsequently, the tatami floor 10 formed in this way is the thickness of the tatami surface 20 (3 mm) so that the finished size of the small unit tatami S is (short side; 340 ± 20 mm) × (long side; 850 mm). Was cut into a size of (short side; (340-3 × 2) ± 20 mm) × (long side; 850-3 × 2 mm) to obtain a tatami floor 10 for the small unit tatami S. Also, the final size of the large unit tatami M is (short side; 510 ± 20 mm) × (long side; 850 mm) by subtracting 3 mm of the thickness of the tatami table 20 to obtain (short side; (510-3 × 2 ) ± 20 mm) × (long side; 850 mm−3 × 2 mm) to obtain a tatami floor 10 of a large unit tatami mat M.
Here, the tatami mat is cut into a square shape of (850 mm−3 × 2 mm) × (850 mm−3 × 2 mm) size corresponding to a half tatami mat that is half the size of one tatami mat, and then cut into a predetermined size of the square shape. By dividing the pair of opposite sides of the floor 10 at a size ratio of 2: 3, design change within a range of ± 20 mm is allowed at this time, and the small unit tatami mat S is formed (short side; (340-3 × 2) ± 20 mm) × (long side; 850-3 × 2 mm) size tatami floor 10 and the large unit tatami M (short side; (510-3 × 2) ± 20 mm) × (long side; A tatami floor 10 having a size of 850 mm-3 × 2 mm) was obtained.

  In particular, with respect to the tatami floor 10 cut into a square shape of (850 mm−3 × 2 mm) × (850 mm−3 × 2 mm) size, in a cutting with a size ratio of 2: 3 on a pair of opposing sides, Even if the tatami floor 10 is thin, it can be cut with high dimensional accuracy using existing equipment, the manufacturing work is easy, and it can be processed at low cost.

Next, the cushion material 13 side of the tatami floor 10 is placed on the back surface of the tatami mat 20 formed or coated with a synthetic resin and cut into a predetermined size, and the tatami mat floor 10 is placed on the tatami mat floor 10. Then, the sheet is folded so as to wrap around from the side surface to the back surface of the back sheet 14 of the tatami floor 10, and an adhesive tape is attached as a temporary fixing tape along the end portion thereof to temporarily fix the tatami floor 10.
In this embodiment, the tatami table 20 constituting the small unit tatami S is cut into, for example, a size of 360 mm × 870 mm or more, and the tatami table 20 constituting the large unit tatami M is cut into, for example, a size of 530 mm × 870 mm or more. The end of the tatami mat 20 that covers the tatami mat 10 is folded back to the back surface (lower surface) of the tatami floor 10 and is tacked or sewn on the back surface of the tatami floor 10.

At this time, in this embodiment, a double-sided adhesive tape is disposed between the back surface of the tatami mat 20 formed or coated with a synthetic resin and the upper surface of the tatami floor 10 (upper surface of the cushion material 13). 20 and tatami floor 10 are joined and adhesion is improved. By using a double-sided adhesive tape, there is no adverse health effect due to the volatilization of the solvent of the solvent-based adhesive.
In addition, when attaching the tatami surface 20 to the tatami floor 10, the tatami surface 20 is bent while being pressed along the side (edge) of the tatami floor 10, and the back surface of the tatami floor 10 is pressed while being pushed toward the center. Go. By performing the press treatment, the adhesion between the tatami floor 10 and the tatami surface 20 can be further improved, the crease or weaving unevenness of the surface of the tatami surface 20 can be eliminated, the unevenness can be eliminated, and the appearance can be improved by adjusting the contour.

  Further, in this embodiment, the end portions of the adjacent sides of the tatami mat table 20, that is, the overlapping portions (overlap of the tatami mat table 20) at the corners of the four corners of the tatami floor 10 are cut, and the cut portions are further waxed (hot melt adhesive). By joining and solidifying with, the unraveling and peeling of the cut portion are prevented, and the appearance and appearance are good. By cutting the overlapping part in this way, the entire thickness of the small unit tatami mat S and the large unit tatami mat M becomes substantially uniform, and can be laid without causing a gap between the floor base material and at the time of depression. There is no sense of incongruity due to the sinking and it is comfortable to use. Further, it is difficult for gaps to be formed between the corners and sides of adjacent tatami mats when laid, and adhesion is improved, and dust and dust are prevented from entering the gaps. Furthermore, the use of wax, which is a hot-melt adhesive that does not contain an organic solvent, provides low cost and high adhesive strength, and does not adversely affect health.

In the small unit tatami mat S and the large unit tatami mat M of this embodiment, the tatami mat 20 is attached and fixed to the tatami mat 10 by tacking or sewing along the end of the tatami mat 20 that covers the tatami mat 10. Is done.
Furthermore, in the present embodiment, the anti-slip material 30 is joined and attached to the back surface of the tatami floor 10 covered with the tatami surface 20 with a double-sided adhesive tape. By using a double-sided adhesive tape, there is no adverse health effect due to the volatilization of the solvent of the solvent-based adhesive.
In FIG. 2, the plastic corrugated cardboard 12 has a size and shape smaller than that of the insulation board 11 and the back material 14 covers the side and bottom surfaces of the plastic corrugated cardboard 12 so that the tatami mat 20 wraps around the back side. In the portion where 20 is wound around the back surface side, the back material 14 is directly disposed on the lower surface of the insulation board 11.
In addition, there is also an area where the step difference at the boundary with the tatami surface 20 can be absorbed by the cushioning properties (elasticity) of the cushion material 13 and the anti-slip material 30.

In this way, the ratio of the short side to the long side is 2: 5 (short side; 340 ± 20 mm) × (long side; 850 mm), the rectangular small unit tatami mat S, or the ratio of the short side to the long side. A large unit tatami mat M of 3: 5 (short side; 510 ± 20 mm) × (long side; 850 mm) is obtained. These form a semi-tatami of square (850 mm) × (850 mm) size by combining one long side of each other.
In this embodiment, the ratio of the short side to the long side is 2: 5 (short side; 340 ± 20 mm) × (long side; 850 mm), and the rectangular small unit tatami mat S is 1 or 2 or more. The ratio of the short side to the long side is 3: 5 (short side; 510 ± 20 mm) × (long side; 850 mm). The floor structure 1 is formed by the combination of the tatami mats M.

  According to the floor structure 1 according to this embodiment and this example, the ratio of the short side to the long side is 2: 5 (short side; 340 ± 20 mm) as shown in FIG. ) × (long side; 850 mm) rectangular small unit tatami mat S or 1 or 2 and the ratio of short side to long side is 3: 5 (short side; 510 ± 20 mm) × (long side; 850 mm) The small unit tatami mat M in the rectangular shape is a combination of one or two or more small unit tatami mats S and the large unit tatami mat M, and the small units are arranged in parallel in the longitudinal direction and the short direction. For one small unit tatami S and / or a large unit tatami M arbitrarily selected from the tatami S and the large unit tatami M, one small one selected arbitrarily from the small unit tatami S and the large unit tatami M separately. Two small units with unit tatami mat S or large unit tatami mat M arranged in parallel The tatami mat S and / or the large unit tatami M are adjacent to each other at right angles with their longitudinal and transverse directions reversed, and a T-shape or an inverted T-shape is formed by three adjacent sides. In other words, in the longitudinal direction of two small unit tatami mats S and / or large unit tatami mats M arranged in parallel in the same direction, another small unit tatami mat S or large unit Arrangement so that the short direction of the tatami mat M is the same direction (in other words, another one with respect to the short direction of the two small unit tatami mats S and / or the large unit tatami mat M arranged in the same direction) 4 pieces of small unit tatami S or large unit tatami M are arranged in such a way that the longitudinal directions of the small unit tatami S or the large unit tatami M are in the same direction). The whole room, which is also a standard for Japanese-style rooms, is a square-shaped 2cm (Fig. 4 ( a)) It can be laid corresponding to 4 帖 and half (4.5 帖) (Fig. 5 (b)), 8 帖 (Fig. 7 (a)) and the like. Further, 6 と す る (FIG. 6A) having a rectangular shape as a whole is also possible.

  Therefore, even when laid as a tatami mat on a flooring floor in a living room, etc., it is possible to prevent misalignment that easily occurs when four corners of a tatami are concentrated in one place, and a gap is created between adjacent tatami mats. The arrangement is difficult to prevent, and it can be kept hygienic by preventing dust and dust from accumulating in the gaps, and it can be kept sanitary. It is small in size and easy to use.

However, to correspond to the complex between (corporation, fifty-six between) Size (850mm × 1700mm = 1.445m ²⁾ of hissing size half of the square (850mm × 850mm = 0.7225m ²⁾ of tatami standards as in Example Thus, the size of the rectangular small unit tatami S divided by a size ratio of 2: 3 on a pair of opposite sides of the semi-tatami mat is (short side; 340 ± 20 mm) × (long side; 850 mm) = 0 .289 ± 0.017 m ² , and the size of the rectangular large unit tatami M is (short side; 510 ± 20 mm) × (long side; 850 mm) = 0.4335 ± 0.017 m ² .
And when it is defined as 1 mm size = 850 mm × 1700 mm = 1.445 m ² , one small unit tatami S (0.289 ± 0.017 m ² ) and a rectangular large unit tatami M (0.4335 ± 0.017 m) ² ) 0.5 帖 size = 0.7225m ^{2 by} combining 1 sheet, ² small unit tatami mats S (0.289 ± 0.017m ² ) and rectangular large unit tatami mat M (0.4335 ± 0. 017 m ² ) is a combination of two pieces, so that 1 cm size = 1.445 m ² .

These figures show an example of arrangement and combination, and the number, arrangement and combination of the small unit tatami mat S and the large unit tatami mat M are selected according to the user's preference and usage.

  And in the floor surface structure 1 of this invention, the ratio of a short side and a long side which forms the semi-tatami of square shape (850mm) x (850mm) size by match | combining one long side of each other is 2: 5 (short side; 340 ± 20 mm) × (long side; 850 mm) rectangular small unit tatami S and the ratio of short side to long side is 3: 5 (short side; 510 ± 20 mm) × It is a combination of rectangular large unit tatami mats (long side; 850 mm). The small unit tatami mat S and the large unit tatami mat M are rectangular and have a direction such as a longitudinal direction or a short direction. Designs such as regular, irregular (random), and symmetrical can be produced by arranging and combining the same directionality or changing the directionality, and various external shapes and internal mosaic patterns can be expressed.

  In particular, each small unit tatami S and large unit tatami M are rectangular, and the ratio of the short side to the long side is 2: 5 and the ratio of the short side to the long side is 3: 5. The combination of unit tatami mats gives an overall sense of unity and is excellent in visual balance.

  Here, in the combination of a small unit tatami with a ratio of short side to long side of less than 2: 5 and a large unit tatami with a ratio of short side to long side exceeding 3: 5, the ratio of short side to long side is 2: When the aspect ratio of the small unit tatami less than 5 is large and slender, it is visually emphasized and the balance becomes poor. Moreover, when trying to correspond to an intermediate size between 1 の 間, 2 帖, 3 帖, 4 帖, 5 帖, 6 帖, 7 帖, 8 帖, etc., the overall shape is limited to an L-shaped array, In addition, even when it corresponds to 3 帖, 4 帖, 5 帖, 7 帖 other than conventional tatami mat standards such as 4.5 帖, 6 帖, 8 帖, etc., the overall aspect ratio is large and the overall shape is elongated. Limited to a rectangular shape. In addition, it is difficult to cut the tatami floor 10 constituting the small unit tatami mat S with high dimensional accuracy using existing facilities in tatami mat manufacturing, and the manufacturing cost increases. Furthermore, when the ratio of the short side to the long side of the small unit tatami is less than 2: 5, the light weight is reduced, so that the shift tends to occur. In addition, warpage deformation is likely to occur, and manufacturing costs further increase if warpage deformation is to be suppressed.

  However, in the present invention, a small unit tatami mat is formed by combining a rectangular small unit tatami mat S having a short side to long side ratio of 2: 5 and a rectangular large unit tatami mat M having a ratio of the short side to long side of 3: 5. The rectangular shape of the S and large unit tatami M gives a sense of overall unity, a well-balanced visual appearance and excellent design, and further, 1 帖, 2 帖, 3 帖, 4 帖Intermediate sizes between 5mm, 6mm, 7mm, 8mm, etc., 3mm, 4mm, 5mm, 6mm, other than traditional tatami mat standards such as 4.5mm, 6mm, 8mm, etc. Even when it corresponds to 7 mm, etc., it is not limited to the arrangement in which the overall shape is L-shaped or the overall aspect ratio is large and the overall shape is an elongated rectangular shape, and the overall aspect ratio difference is small. Visually well-balanced outer shape representation with the overall shape approaching a square is possible, and the design surface has a high degree of freedom of representation. Of course, since the square shape is formed by combining one long side of the small unit tatami S and the large unit tatami M, it is also possible to represent a square design surface. In addition, it is possible to perform cutting with a certain quality with high dimensional accuracy using existing equipment. Further, it is difficult to cause displacement and warping deformation when laid, and it is easy to use, and the manufacturing cost can be kept low.

  And in the conventional square-shaped semi-tatami mats, there are limited variations to the extent that a checkered pattern can be expressed even if tatami mats with different patterns, colors, and materials are combined, but in the floor structure 1 of the present invention, By combining one long side, a square (850 mm) × (850 mm) size semi-tatami is formed, and the ratio of short side to long side is 2: 5 (short side; 340 ± 20 mm) × (long Rectangular small unit tatami mat S with sides: 850 mm) and rectangular large unit tatami mat M with a ratio of short side to long side of 3: 5 (short side: 510 ± 20 mm) × (long side: 850 mm) As a result of this combination, various arrangements in which the orientation of the small unit tatami mat S and the large unit tatami mat M are the same or changed, as well as an increased combination pattern, are possible, and the patterns, colors, materials, etc. are different. Unit Tatami S and large unit When the tatami mat M is combined, the range of design expression is further expanded and variations are increased, and various external shapes and internal mosaic patterns can be expressed.

Therefore, it has a decorative effect of greatly changing the design and the atmosphere of the room according to the needs of the user, etc., and it is possible to produce a different atmosphere for each room, corresponding to the diversification of interior design. For example, it is possible to form a tatami space like a Japanese-style room by laying a small unit tatami S and a large unit tatami M in the western world, and laying the small unit tatami S and the large unit tatami M in a conventional Japanese room. It is also possible to produce a Western-style atmosphere. And since the arrangement | positioning which does not concentrate four corners of the small unit tatami mat S and the large unit tatami mat M in one place is possible, it can be matched also with a Western style design. In addition, the atmosphere can be easily changed and the pattern can be changed by changing the number and the arrangement of the laying, and a variety of external shapes and internal mosaic patterns can be expressed.
Therefore, it becomes easy to use according to the user's lifestyle, preferences, personality, room usage, floor plan / structure, installation location, and the like.

  A rectangular small unit tatami mat S having a ratio of a short side to a long side of 2: 5 (short side; 340 ± 20 mm) × (long side; 850 mm) constituting the floor structure 1 of the present embodiment; A rectangular large unit tatami mat M having a short side to long side ratio of 3: 5 (short side; 510 ± 20 mm) × (long side; 850 mm) has a square (850 mm) × (850 mm) size. The half tatami mats are divided into 2: 3 on a pair of opposite sides, and are smaller and lighter than conventional half tatami mats, making them extremely easy to handle during transportation and laying on the underfloor material. Can also be done easily. Moreover, even when it gets dirty, cleaning such as replacement or tatami drying can be easily performed, which is economically excellent and can be maintained at low cost. Furthermore, it can be stored even in a narrow space, and the stored item can be easily taken out. In addition, since it is lightweight, there is little load applied to the building floor support structure, and the durability of the building can be improved. In addition, it is possible to change the atmosphere as a room accent or decoration even in a small space.

  In particular, the tatami surface 20 formed or coated with a synthetic resin has high strength and durability, and also has low water absorption, so that it can be easily cleaned and easily cleaned and easily maintained hygienically. It is. Therefore, not only general households, but also restaurants, etc. that require cleanliness and ease of cleaning, etc., floors such as inns and rooms that have a heavy load on flooring and require frequent replacement It is also suitable as a flooring material for offices or the like that has a heavy load on the material. Furthermore, in addition to being small and lightweight, various arrangements and combination patterns are possible as described above. By the way, it can be laid.

  In the floor surface structure 1 of this embodiment, the small unit tatami S and the large unit tatami M can be used as a laying laying on a flooring or the like, and the ratio of the short side to the long side can be used. Is 2: 5 (short side; 340 ± 20 mm) × (long side; 850 mm) and the rectangular unit tatami mat S has a ratio of the short side to the long side of 3: 5 (short side; 510 ± 20mm) x (long side; 850mm) rectangular large unit tatami mat M is combined with the long side of the traditional tatami mat so that it becomes the standard size between the conventional 4mm and 6cm, 6cm and 8mm. It is also possible to lay the floor plan in a Japanese-style room without creating any gaps or lifts.

  In particular, according to the floor surface structure 1 of the present embodiment, the small unit tatami S and the large unit tatami M have a thin thickness within a range of 10 to 20 mm and a rectangular shape, thereby representing a smart aesthetic. it can. In addition, even when laid on a flooring floor or the like, the level difference is small, and it is possible to effectively prevent a fall due to rolling or the like. Moreover, even when it is laid on the floor surface on which floor heating is installed, the heat conductivity from the floor heating becomes high, and the heat from the floor heating floor can be efficiently transmitted to the tatami mat 20. . Furthermore, when it is within the range of 10 to 18 mm, it can be laid under an open / close door or the like of a closet that is set apart from the floor surface by 20 mm or more in an apartment, an apartment, etc., and the degree of installation flexibility is increased.

  Thus, the floor surface structure 1 of the present embodiment is divided at a size ratio of 2: 3 on a pair of opposing sides of a square half tatami mat having a predetermined standard (850 mm) × (850 mm) size. A rectangular small unit tatami S with a size of 2/5 square half tatami mat and a ratio of short side to long side of 2: 5 (short side; 340 ± 20 mm) × (long side; 850 mm) It consists of a combination of large unit tatami mats M with a 3/5 size and a short side to long side ratio of 3: 5 (short side; 510 ± 20 mm) × (long side; 850 mm). The large unit tatami M has an insulation board 11 as a wood board and a plastic corrugated cardboard 12 as a synthetic resin board as a core material, and a cushion material 13 made of non-woven fabric is disposed on the upper layer of the core material. Back side made of synthetic resin in the lower layer The tatami floor 10 on which the material 14 is disposed and laminated is covered with a tatami surface 20 formed or coated with a synthetic resin, and an anti-slip material 30 made of a synthetic resin foam is attached to the back surface thereof. is there.

  Therefore, according to the floor structure 1 of the present embodiment, a core material composed of an insulation board 11 as a wooden board and a plastic corrugated cardboard 12 as a synthetic resin board, and a cushion material composed of a non-woven fabric disposed in the upper layer of the core material 13 and by forming a tatami floor with a synthetic resin back material 14 disposed in the lower layer of the core material, a tatami floor can be formed simply by sequentially stacking pre-formed boards, etc. In addition, it is very light and easy to handle, and can be easily cut into a rectangular shape with a predetermined size using existing facilities in tatami mat manufacturing. Then, the small unit tatami formed by covering the tatami floor 10 cut to a predetermined size in this way and covering the tatami surface 20 formed or coated with synthetic resin and attaching the anti-slip material 30 to the back surface thereof. The S and the large unit tatami M are light in weight and can secure high strength, have good durability, are low in cost, have high dimensional accuracy, and have a certain quality. Furthermore, it is highly moisture-proof and can prevent the growth of mold and mites.

In particular, when the core material of the tatami floor 10 is formed by the insulation board 11 as a wooden board, the antibacterial properties, moisture conditioning properties, deodorizing properties, heat insulating properties, soundproofing / sound absorbing properties, etc., which are the characteristics of wood are exhibited, and the humidity is high. Even when used under the environment, the growth of mites, molds, etc. is suppressed, and it is difficult to corrode and a stable quality is maintained.
Further, when plastic corrugated cardboard 12 as a synthetic resin board is used in addition to insulation board 11 as a core material, high strength can be secured even though it is lightweight, and durability is further improved. Expansion and warping deformation due to humidity can also be suppressed.
In addition, the cushioning material 13 made of a non-woven fabric disposed on the upper layer of the tatami floor 10 has high cushioning properties, can be expected to have a soundproofing / soundproofing effect, and can absorb variations in dimensions. Moreover, air permeability is also securable by being comprised with the nonwoven fabric.
Furthermore, the back surface is reinforced by the synthetic resin back material 14 disposed in the lower layer of the tatami floor 10, and warpage deformation is further prevented.

  Further, since the anti-slip material 30 is attached to the back surfaces of the small unit tatami S and the large unit tatami M, displacement is prevented even when laid on a flooring floor or the like. Therefore, it can be kept hygienic by preventing dust and dust from accumulating in the gap caused by the misalignment, and tick breeding, and there is less time to correct the misalignment and there is a risk of falling due to the misalignment. Is also small and improves usability.

  Then, by combining the small unit tatami mat S and the large unit tatami mat M having a predetermined size with such a configuration, the small unit tatami mat S and the large unit tatami mat S arranged in parallel and adjacent to each other with the same longitudinal direction and short direction are arranged. One small unit tatami S arbitrarily selected from the small unit tatami S and the large unit tatami M separately for the two small unit tatami S and / or the large unit tatami M arbitrarily selected from the unit tatami M The large unit tatami M is adjacent to the two small unit tatami S and / or the large unit tatami M arranged in parallel with each other at a right angle with the longitudinal direction and the short direction reversed. Arrangement so that adjacent sides of the unit tatami S and the large unit tatami M form a T shape, that is, two small unit tatami S and / or large unit tatami M arranged in parallel in the same direction Against the longitudinal direction of Arrangement so that the short direction of another small unit tatami S or large unit tatami M is the same direction (in other words, two small unit tatami S and / or large unit tatami arranged in parallel in the same direction) The corners of the small unit tatami S and the large unit tatami M are assembled in such a way that the longitudinal direction of another small unit tatami S or the large unit tatami M is the same in the short direction of M. These four are not collected in one place, and can be laid corresponding to 2 squares, 4 half halves, 8 squares, etc. with a square shape as a whole. Furthermore, the same can be achieved with a 6-inch or the like having a rectangular shape as a whole.

Therefore, even when laid as a tatami mat on a flooring floor in a living room, etc., it is possible to prevent misalignment that tends to occur when four corners of the tatami are concentrated in one place, and adjacent small unit tatami S and large unit tatami mats. The arrangement makes it difficult to create a gap between each other, preventing dust and dust from accumulating in the gap and facilitating the propagation of ticks and keeping it hygienic, and correcting misalignment There is little effort, the risk of falling due to slippage is small, and laying is easy to use.
In addition, the small unit tatami S and the large unit tatami M are smaller and lighter than the conventional half tatami mats, so that they can be easily carried and laid, and can be easily changed and replaced. It can be stored even in a small space-saving space.

  In addition, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm Therefore, it is possible to express an intermediate size between 7.5 cm, 8 cm, and the like, and the variation of the size that can be expressed is increased, so that it is possible to cope with the needs of the user. In addition, intermediate sizes between 1mm, 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, etc., other than conventional tatami mat standards such as 4.5mm, 6mm, 8mm Even if it corresponds to 3 帖, 4 帖, 5 帖, 6 帖, 7 帖, etc., the overall shape is an L-shape, or the overall shape is large, and the overall shape is an elongated rectangular shape. It is not limited to this, but the overall aspect ratio is small and the overall shape is close to a square, so that a visually balanced external shape can be expressed. Of course, the small unit tatami mat and the large unit tatami mat are also arranged at this time by arranging the three small unit tatami mats S and the large unit tatami mat M so as to form a T shape or an inverted T shape between adjacent sides. An arrangement is possible that does not allow the four corners of M to be collected in one place.

  Here, the ratio of the short side to the long side is set to 2: 5 (short side; 340 ± 20 mm) × (long side; 850 mm), and the ratio of the short side to the long side is set to 3: 5. The numerical value of the large unit tatami mat M (short side; 510 ± 20 mm) × (long side; 850 mm) was determined by the present inventors as a result of intensive experiments and the ratio of the short side to the long side was 2: 5. (Short side; 340 ± 20 mm) × (Long side; 850 mm) rectangular small unit tatami mat S and the ratio of short side to long side is set to 3: 5 (short side; 510 ± 20 mm) × (long side 850 mm) By forming the floor structure 1 in combination with the rectangular large unit tatami mat M, there is an overall sense of unity, visually balanced, excellent appearance and design, and 1中間, 2 帖, 3 帖, 4 帖, 5 帖, 6 帖, 7 帖, 8 帖 etc. intermediate size, 4.5 従 来, 6 帖, 8 帖 etc. Even if it corresponds to 3 帖, 4 帖, 5 帖, 6 帖, 7 帖, etc. other than the tatami standard, the overall shape is L-shaped and the overall aspect ratio is large, and the overall shape is an elongated rectangular shape. It is not limited to the arrangement, and the overall aspect ratio is small and the overall shape is close to a square. It was found based on this finding that it can be cut with high quality, and that it is easy to use and less prone to misalignment and warping deformation when laid, and can be manufactured at low cost. .

The small unit tatami S and the large unit tatami M are rectangular and have a direction such as a longitudinal direction or a short direction. It is possible to produce designs such as regular, irregular (random), and symmetrical designs. When combining small unit tatami mats S and large unit tatami mats M with different patterns, colors, materials, etc. Variations can be increased and various external shapes and internal mosaic patterns can be expressed.
In addition, because it is very lightweight and easy to carry and lay, it is easy to change or replace the number and arrangement of laying even when laying on a flooring floor in a living room, etc. It is also easy to change the external shape and the internal mosaic pattern.
At this time, since the small unit tatami mat S and the large unit tatami mat M are rectangular, there is a sense of unity as a whole, and an excellent visual balance and various external shapes and internal mosaic patterns can be formed with good appearance. Of course, since the square shape is formed by combining one long side of the large unit tatami M and the small unit tatami S, it is also possible to represent a square design surface.
Therefore, it is possible to respond to the user's lifestyle, taste, personality, room usage, floor plan / structure, laying location, etc., and it is excellent in usability.

  In the case of carrying out the present invention, the configuration, shape, material, size manufacturing method, etc. of other parts of the small unit tatami S and the large unit tatami M constituting the floor structure 1 are described in the above embodiment and The present invention is not limited to the examples. For example, a small unit tatami mat S and a large unit tatami mat M that can be provided with the tatami mat 20 on both surfaces of the tatami floor 10 and can form a design surface (use surface) on both the front and back surfaces can be used.
