Description of the Related Art Conventionally, a double-floor structure in which a base material is supported by supporting legs or joists, the base materials are joined with a scrapboard, and a finishing material is arranged on the top surface of the scrapboard, is a detached house, an apartment house, a gymnasium, etc. Widely used in. Here, the conventional double floor is the base material,
The scrapboard and finishing materials were all made of wood.

る。更に、体育館のように床面積が大きくなると、床弾
性や床強度のバラツキが大きくなるという問題もある。However, if the entire double floor is made of a wood material, the entire floor expands and contracts due to the moisture absorption characteristics of the wood, which causes the problem that the floor surface is warped, floated, or has a gap. is there. In addition, there is a risk of deterioration due to decay fungi and termites, so there is a problem in long-term durability. Further, when the floor area is large like in a gymnasium, there is a problem that variations in floor elasticity and floor strength increase.

である。Therefore, although dimensional stability is improved by underfloor ventilation, etc., problems remain in terms of workability and economy. Especially in the gymnasium, a pole for ball games may be set up on the concrete floor base, but due to a slight dimensional change of the double floor, the pole hole of the floor base and the pole hole of the double floor will not match, and the pole will be placed on the floor base. The dimensional stability is extremely important because it causes a problem that the hole cannot be inserted.

【０００６】[0006]
【課題を解決するための手段】本発明は、以上の課題を
解決するためになされたものであって、その要旨は、下
地材の上面に捨板を介して仕上材を積層した二重床であ
って、下地材が合成樹脂材料からなり、捨板が木質材料
からなる二重床に係るものである。The present invention has been made to solve the above problems, and the gist thereof is a double floor in which a finishing material is laminated on the upper surface of a base material via a waste board. The base material is a synthetic resin material, and the wasteboard is a wooden material.
【０００７】また、好ましくは、下地材が熱可塑性樹脂

あり、曲げヤング係数が１３００〜４８００Ｎ／ｍｍ2
である二重床に係るものである。更に、下地材の厚さは
二重床全体の厚さの１／３以上であることが好ましい。Preferably, the base material is made of a thermoplastic resin, the base material has a bending strength of 14 to 50 N / mm 2 , and a bending Young's modulus of 1300 to 4800 N / mm 2.
It is related to the double floor. Further, the thickness of the base material is preferably 1/3 or more of the thickness of the entire double floor.
【０００８】なお、下地材は、クッションゴムを下端に

ち、従来の二重床と全く同様に施工できるものである。The base material may be supported by supporting legs having cushion rubber at the lower end or by joists. That is, it can be constructed exactly like a conventional double floor.
【０００９】[0009]
【発明の実施の形態】本発明の二重床は、下地材が合成

させたものである。BEST MODE FOR CARRYING OUT THE INVENTION In the double floor of the present invention, the base material is made of a synthetic resin material, and at least the scrapboard is made of a wood material. That is, by changing the base material of the base from a conventional wood-based material to a synthetic resin material, it is possible to prevent the occurrence of problems such as warpage, floating, and gaps due to moisture absorption, and to prevent deterioration due to decay fungi or termites. It has been eliminated and its durability has been greatly improved.
【００１０】ここで、下地材の合成樹脂材料は特に限定

好ましい。熱硬化性樹脂であると最終的な破壊形態が木

性樹脂としては、例えば、ポリプロピレン、ポリ塩化ビ
ニール、アクリルニトリル・ブタジエン・スチレン、サ
ーモプラスチック・オレフィン等が使用でき、融合可能
なものならば複数種類混合したものでもよい。Here, the synthetic resin material of the base material is not particularly limited, and other materials may be mixed as long as the synthetic resin is the main component, but it is particularly preferable to use a thermoplastic resin. The thermosetting resin causes a danger of final cracks like wood-like materials, resulting in plate cracks, but a thermoplastic resin only bends, so it is safe to use on the floor of a gymnasium where a large impact is applied. That's why. The thermoplastic resin may be, for example, polypropylene, polyvinyl chloride, acrylonitrile / butadiene / styrene, or thermoplastic / olefin, and may be a mixture of a plurality of types as long as they can be fused.

を一体的に接着すればよい。Further, the synthetic resin material of the base material is not limited to an unused one, and a recycled resin using a synthetic resin waste material obtained from a removed automobile bumper or battery case can be used. In order to use recycled resin as a base material for a double floor, for example, granulated recycled resin is melted by frictional heat, and granular plant pulverized products are mixed to form a porous plate at a low pressure so that it becomes porous. To form an intermediate resin layer, and the upper and lower surfaces of the intermediate resin layer may be integrally bonded with a thin plate-like skin.

材料とすることが好ましい。On the other hand, as the resin characteristics of the base material used for the double floor, in addition to problems such as warping, floating, and gaps due to expansion and contraction,
Loading of heavy objects, walking feeling, and floor impact noise also pose problems, so the bending strength is 14 to 50 N / mm 2 regardless of whether it is a thermoplastic resin or a thermosetting resin, and the bending Young's modulus Is preferably 1300 to 4800 N / mm 2 .

しいものではない。That is, when it is used as a structural member of a gymnasium or the like, it is necessary to consider loading heavy objects. Here, when a local load is applied to the floor surface, the floor surface bends and the load on the legs increases, eventually leading to destruction, but the floor strength is the entire system (base material, scrapboard, finishing material). However, the bending strength of the base material becomes a problem because it depends most on the base material. Therefore, the bending strength of the base material is 14 N / mm
If it is less than 2 , it may not be possible to cope with the maximum load (breaking load) that can be assumed. In addition, to increase the floor strength,
Although it is possible to solve the problem by increasing the plate thickness or narrowing the leg pitch, it is not preferable in terms of economy due to the increase in the weight of members and the number of legs.
【００１４】一方、下地材の曲げ強さを５０Ｎ／ｍｍ2
を越えて強くしても、もはや必要十分であるばかりでな
く、経済性を悪化させるだけなので、意味がない。On the other hand, the bending strength of the base material is 50 N / mm 2
There is no point in strengthening beyond the limits because it is not only necessary and sufficient, but also worsens economic efficiency.

には歩行感が悪くなる。Next, in a sports floor such as a gymnasium, in addition to floor strength, floor elasticity becomes a problem. This is related to easy exercise and safe competition, and the Young's modulus of bending influences. In addition, sound insulation and walking sensation become problems for residential use, and the bending Young's modulus also affects them. Here, if the floor is soft, shock absorption increases, but if the bending Young's modulus of the base material is less than 1300 N / mm 2 , the damping time becomes too long. On the other hand, 4800 N / m
When it exceeds m 2 , the repulsive force is strong, the floor impact noise is loud, and the walking feeling is deteriorated.

くても明確である。The thickness of the base material is preferably 1/3 or more of the thickness of the entire double floor. In order to sufficiently suppress the expansion and contraction of wood wasteboards and finishing materials, it is necessary to secure a certain thickness of the underlying material, and if the underlying material thickness is less than 1/3 of the total thickness, This is because there is a possibility that strength problems may occur and the tightening depth of the waste plate fixing screw may not be secured. In addition, since the discarding board and the finishing material are laminated on the upper surface of the base material, the thickness of the base material cannot be the full thickness.Therefore, the upper limit of the thickness of the base material is not specified. Is also clear.

It may be supported by a support leg having a cushion rubber at the lower end or by a joist. However, the use of the support legs with the cushion rubber not only improves sound insulation but also facilitates height adjustment. In this case, the supporting legs are arranged around the base material.For the base material and the support legs, a bracket is attached to the upper ends of the support legs to fix the frame receiving material to the frame receiving material. It may be fixed with screws. It should be noted that the frame receiving material is interposed when the support legs are arranged in the middle of the adjacent base materials and two base materials are supported by one support leg, but the base materials are independently supported. In this case, the receiving metal fitting may be directly fixed to the base material.

Further, a finishing material is further fixed to the upper surface of the throwing plate, but when nailing the both materials, it is preferable that the tips of the nails reach the base material.

In the double floor of the present invention, the material of the finishing material is not limited, and a wood material or a carpet material can be used.
