Are laminated by hand lay-up molding.

このような構成とすることで、最表樹脂層３をプレス成形によらずに形成することが可能となる。   By setting it as such a structure, it becomes possible to form the outermost resin layer 3 without using press molding.

本発明にあっては、床パンの表面のどの部分に残水があるかが一見して分かるようになるため、残水のある部分を踏んで足の裏が濡れて不快に感じたり、特に靴下を履いている時に不快に感じる上に靴下を乾かさなければならない、といったことを回避することができる。   In the present invention, it becomes possible to understand at a glance which part of the surface of the floor pan has residual water. It is possible to avoid feeling uncomfortable when wearing socks and having to dry the socks.

以下、本発明の実施形態について図面に基づいて説明する。床パン１は、浴室の床スラブ上に設置されて入浴スペースとなるもので、上面の一部が浴槽設置部となると共に残りの部分が洗い場床面となるか、あるいは、洗い場床面となる部分にのみ設置される。いずれにしても、少なくとも洗い場床面を備えている。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. The floor pan 1 is installed on a bathroom floor slab to become a bathing space, and a part of the upper surface serves as a bathtub installation part and the remaining part serves as a washing ground floor or a washing ground floor. Installed only in the part. In any case, at least the washing floor is provided.

本発明では床パン１は、基材樹脂層４となる合成樹脂の表面側（上面側）に、最表樹脂層３となる合成樹脂を積層して形成される。基材樹脂層４は、ＦＲＰをはじめ種々の合成樹脂で成形される。最表樹脂層３は、基材樹脂層４の少なくとも洗い場床面となる部分の表面に形成され、浴槽設置部となる部分の表面に形成してもよい。   In the present invention, the floor pan 1 is formed by laminating the synthetic resin to be the outermost resin layer 3 on the surface side (upper surface side) of the synthetic resin to be the base resin layer 4. The base resin layer 4 is formed of various synthetic resins including FRP. The outermost resin layer 3 may be formed on the surface of at least the portion of the base resin layer 4 that becomes the washing floor, and may be formed on the surface of the portion that becomes the bathtub installation portion.

最表樹脂層３は、主体をなす合成樹脂に、粒径２ｍｍ以上のシリカゲル２を２０重量部以上及び呈色材を混入させたものである。ここで、重量部とは総重量に対する重量％とする。
主体をなす合成樹脂としては、ＦＲＰやアクリル樹脂が好適に用いられるもので、アクリル樹脂は耐薬品性に優れている。 The outermost resin layer 3 is obtained by mixing 20 parts by weight or more of a silica gel 2 having a particle diameter of 2 mm or more and a colorant into a main synthetic resin. Here, the weight part is weight% with respect to the total weight.
As the main synthetic resin, FRP or acrylic resin is preferably used, and the acrylic resin is excellent in chemical resistance.

シリカゲル２は、広く知られているため詳細には説明しないが、ＳｉＯ２・ｎＨ２Ｏで表される多孔質の物質で、乾燥剤・吸着剤として機能すると共に、加熱することにより吸着した水や臭い成分等の物質を放出する。 Although silica gel 2 is widely known and will not be described in detail, it is a porous substance represented by SiO 2 · nH 2 O and functions as a desiccant / adsorbent and is also adsorbed by heating. Releases substances such as odor components.

呈色材は、水分を吸収すると色が変化するもので、例えば塩化コバルトが好適に用いられる。塩化コバルトは、乾燥していると青くなり、水分を吸収すると赤くなる。   The coloring material changes its color when it absorbs moisture, and for example, cobalt chloride is preferably used. Cobalt chloride turns blue when dry and red when it absorbs moisture.

床パン１の製造は、基材樹脂層４及び最表樹脂層３をプレス成形する方法か、基材樹脂層４をプレス成形等により成形した後、最表樹脂層３をハンドレイアップ成形により積層する方法が主に採られている。   The floor pan 1 is manufactured by press-molding the base resin layer 4 and the outermost resin layer 3, or by molding the base resin layer 4 by press molding or the like, and then forming the outermost resin layer 3 by hand lay-up molding. The method of laminating is mainly adopted.

プレス成形する場合には、最表樹脂層３となる、不織布に合成樹脂を含浸させてなるシート（すなわちＳＭＣ（シートモールディングコンパウンド））を、基材樹脂層４となる合成樹脂に重ねてプレスすればよく、プレス成形により容易に最表樹脂層３を形成することができる。   In the case of press molding, a sheet (that is, SMC (Sheet Molding Compound)) obtained by impregnating a non-woven fabric with a synthetic resin, which becomes the outermost resin layer 3, is overlaid on the synthetic resin to be the base resin layer 4 and pressed. The outermost resin layer 3 can be easily formed by press molding.

ハンドレイアップ成形により積層する場合には、予め形成した基材樹脂層４となる合成樹脂に、最表樹脂層３をハンドレイアップ成形により積層するもので、この場合には最表樹脂層３の主体をなす合成樹脂としてアクリル樹脂が好適に用いられる。これにより、最表樹脂層３となるアクリルゲルコート層をプレス成形によらずに形成することが可能となり、最表樹脂層３をプレス成形にて形成するための金型が不要となり、初期費用を抑えることができる。   In the case of laminating by hand lay-up molding, the outermost resin layer 3 is laminated by hand lay-up molding on a synthetic resin to be the base resin layer 4 formed in advance. In this case, the outermost resin layer 3 Acrylic resin is preferably used as the synthetic resin. This makes it possible to form an acrylic gel coat layer that will be the outermost resin layer 3 without using press molding, eliminating the need for a mold for forming the outermost resin layer 3 by press molding. Can be suppressed.

本発明では、床パン１の表面に残水があると、シリカゲル２により床パン１の表面の残水が吸収されると共に、呈色材により色の変化が生じる。このため、床パン１の表面のどの部分に残水があるかが一見して分かるようになり、色が変化した部分を避けて床パン１の表面を踏むことで、足の裏が濡れて不快に感じたり、特に靴下を履いている時に、不快に感じる上に靴下を乾かさなければならない、といったことを回避することができるものである。   In the present invention, if there is residual water on the surface of the floor pan 1, the residual water on the surface of the floor pan 1 is absorbed by the silica gel 2 and a color change is caused by the colorant. For this reason, it becomes possible to see at a glance which part of the surface of the floor pan 1 has residual water, and by stepping on the surface of the floor pan 1 while avoiding the part where the color has changed, the sole of the foot gets wet. It is possible to avoid feeling uncomfortable or feeling uncomfortable, especially when wearing socks, and having to dry the socks.

また、床パン１の内部又は下面に暖房手段を設けてもよい。暖房手段としては特に限定されず、電熱ヒータや温水床暖房等が用いられる。暖房手段により床パン１を加熱することにより、シリカゲル２が吸収した水分を放出させることが可能となる。   Moreover, you may provide a heating means in the inside of a floor pan 1, or a lower surface. It does not specifically limit as a heating means, An electric heater, a warm water floor heating, etc. are used. By heating the floor pan 1 with the heating means, it is possible to release the moisture absorbed by the silica gel 2.

また、最表樹脂層３にエンボスや微細凹凸等の凹凸を設けてもよい。エンボスの凹凸により、床パン１の表面を滑り難くすることが可能となる。   Further, the outermost resin layer 3 may be provided with unevenness such as embossing and fine unevenness. The surface of the floor pan 1 can be made difficult to slip due to the unevenness of the emboss.
