The front side is made of natural stone, giving it an excellent aesthetic appearance, and the back side is reinforced with a reinforcing layer and backer material, which provide excellent bending strength and an enhanced impact absorption effect. Furthermore, by providing the reinforcing layer, the thickness of the natural stone slab can be reduced, making it lighter overall and easier to handle, making it easier to replace when it is damaged or contaminated.

れる。In addition, the synthetic fiber sheet that makes up the reinforcing layer has strength,
From the viewpoint of durability, sheets made of one or more types of fibers selected from polyester fibers, polyethylene fibers, polyamide fibers, etc. are used, but in order to obtain the strength and durability suitable for the purpose. It is preferable to use a high-strength material having a primordial strength of 5 g/denier or more, more preferably 8 g/denier or more. The form of the synthetic fibers is not particularly limited as long as it is in the form of a sheet, and may be either woven or knitted fabric or non-woven fabric, but long-fiber woven fabric is particularly preferred in terms of enhancing the reinforcing effect. The type of fabric may be plain weave, twill weave, satin weave, etc., but plain weave (mesh weave) is most preferable in terms of facilitating penetration of the synthetic resin and forming a homogeneous reinforcing layer. This sheet-like material has a basis weight of 50 g/aa from the viewpoint of weight reduction and reinforcement effect enhancement.
It is desirable to use one with a weight of about 500 g/m.

Just let it solidify. Of course, it is also possible to adopt a method in which the solvent is impregnated with a solvent solution and then the solvent is removed by volatilization. The preferred amount of synthetic resin to be composited into the synthetic fiber sheet is 500 to 100,037 m2,
More preferably, it is in the range of 600 to 70,037 m2.

After coating and impregnating the synthetic resin, the synthetic resin is cured or solidified by a predetermined method, and after the synthetic resin is completely cured, the backer material is bonded using an adhesive. In this case, the use of an adhesive can be omitted if the backer material is overlapped and pressure-bonded before the synthetic resin is cured or solidified.

［発明の効果］
本発明は以上の様に構成されており、天然石板の裏面に
合成樹脂と複合された合成繊維シートからなる補強層を
設け、さらにこの補強層にバッカー材を貼着することに
より、曲げ強度および耐衝撃性に優れた天然石板床材を
提供し得ることになった。[Effects of the Invention] The present invention is configured as described above, and includes providing a reinforcing layer made of a synthetic fiber sheet composited with a synthetic resin on the back side of a natural stone board, and further adhering a backer material to this reinforcing layer. As a result, it has become possible to provide a natural stone flooring material with excellent bending strength and impact resistance.
また本発明の床材は、同一重量の従来品よりも曲げ強度
および耐衝撃性が優れたものであるから、運搬時や施工
時における破損も少なくなる。Furthermore, since the flooring material of the present invention has better bending strength and impact resistance than conventional products of the same weight, it is less likely to be damaged during transportation or construction.
またバッカー材の効果により、従来のタイルカーペット
施工法をそのまま応用して施工することが可能となり、
従来では天然石板施工に際して必須とされていた特殊な
下地調整なども不要となり、下地の多少の凹凸はバッカ
ー材により吸収でき、また従来のタイルカーペット用接
着剤（アクリル樹脂系等）を用いることにより、石板床
材の施工及び交換を容易に行なうことができる。In addition, the effect of the backer material makes it possible to apply the conventional tile carpet construction method as is.
There is no longer any need for special preparation of the base, which was previously required when installing natural stone slabs. Some irregularities on the base can be absorbed by the backer material, and by using conventional tile carpet adhesives (acrylic resin, etc.) , stone slab flooring can be easily installed and replaced.
