図1に表したように、第1の実施形態に係る浴室用洗い場床1aは、基材11とクッション材20と表面材30とシール部50とを備える。
(First embodiment)
As shown in FIG. 1, the bathroom washing floor 1 a according to the first embodiment includes a base material 11, a cushion material 20, a surface material 30, and a seal portion 50.

下層から、基材11、クッション材20及び表面材30の順に積層される。   From the lower layer, the base material 11, the cushion material 20, and the surface material 30 are laminated in this order.

基材11は、硬質な材料で形成される。すなわち、基材11は、浴室外に湯水を漏出させない防水性、及び浴室壁パネル、天井パネル、風呂椅子、洗面器などの静荷重、使用者の動荷重を受けても撓んだり破損しない強度を有する硬質材料から形成される。基材11は、例えば、FRP(Fiber Reinforced Plastic)等の熱硬化性樹脂、あるいはポリプロピレン、ポリエチレン等の熱可塑性樹脂に補強を施したものから形成される。基材11は、表面材30及びクッション材20よりも機械的強度が高い。   The base material 11 is formed of a hard material. That is, the base material 11 is waterproof so that hot water does not leak out of the bathroom, and is strong enough not to bend or break even when subjected to static loads such as bathroom wall panels, ceiling panels, bath chairs, and basins, and dynamic loads of users. It is formed from the hard material which has. The base material 11 is formed of, for example, a thermosetting resin such as FRP (Fiber Reinforced Plastic) or a material obtained by reinforcing a thermoplastic resin such as polypropylene or polyethylene. The base material 11 has higher mechanical strength than the surface material 30 and the cushion material 20.

表面材30は、基材11の上に設けられる。
表面材30は、縁部32と凹部31とを有する。表面材30は、縁部32において、基材11と接着されている。
凹部31は、縁部32よりも内側に設けられた部分であり、表面材30と基材11とを積層した時に、基材11の側に対向する側の面が縁部32に対して凹状に形成された部分である。すなわち、凹部31は、基材11に対向する側が後退した部分であり、凹部31は、表面材30と基材11とを積層した時に、下側に開口している。
The surface material 30 is provided on the base material 11.
The surface material 30 has an edge 32 and a recess 31. The surface material 30 is bonded to the base material 11 at the edge portion 32.
The concave portion 31 is a portion provided inside the edge portion 32, and when the surface material 30 and the base material 11 are stacked, the surface on the side facing the base material 11 is concave with respect to the edge portion 32. It is the part formed. That is, the concave portion 31 is a portion where the side facing the base material 11 is retreated, and the concave portion 31 opens downward when the surface material 30 and the base material 11 are laminated.

すなわち、表面材30は、厚肉部32aと、厚肉部32aよりも内側に設けられた薄肉部31aとを有しており、厚肉部32aは上記の縁部32に相当し、薄肉部31aは上記の凹部31に相当する。そして、表面材30の凹部31は、可撓性を有する程度の厚みで形成されている。   That is, the surface material 30 includes a thick portion 32a and a thin portion 31a provided on the inner side of the thick portion 32a. The thick portion 32a corresponds to the edge portion 32, and the thin portion Reference numeral 31 a corresponds to the recess 31 described above. And the recessed part 31 of the surface material 30 is formed with the thickness which has a flexibility.

表面材30は、浴室用洗い場床としての基本性能を満足できる程度の硬質性を有している。すなわち、表面材30は、耐水性、耐薬品性、耐摩耗性、耐衝撃性など、洗い場床表面に要求される基本性能(耐久性)を満足する材料から形成されている。表面材30には、例えば、FRP、PVC(塩化ビニル)、ポリプロピレン、ポリエチレン、ウレタン樹脂、ポリエステル樹脂、アクリル樹脂、スチレン・ポリエステル・オレフィン・アクリル系の各種エラストマー、EVA、EPDM、シリコンゴムなどのゴム(硬質)系、あるいはこれらを十分な耐久性が期待できる程度の硬さに調整したもの、あるいはこれらをベースに充填材や強化材を加えた複合材料などが用いられる。但し、これらの材料は一例であって、その他、表面材30の材料としては、浴室の一般的な使用に際し十分な耐久性を有するべく強靱な材料であれば良く、前述したものに限られない。   The surface material 30 has a hardness sufficient to satisfy the basic performance as a bathroom washroom floor. That is, the surface material 30 is formed of a material that satisfies basic performance (durability) required for the washing floor surface, such as water resistance, chemical resistance, wear resistance, and impact resistance. For the surface material 30, for example, rubber such as FRP, PVC (vinyl chloride), polypropylene, polyethylene, urethane resin, polyester resin, acrylic resin, various elastomers of styrene / polyester / olefin / acrylic, EVA, EPDM, silicone rubber, etc. (Hard) type, those prepared by adjusting the hardness to such an extent that sufficient durability can be expected, or composite materials obtained by adding fillers and reinforcing materials to these as bases are used. However, these materials are only examples, and the material of the surface material 30 is not limited to those described above as long as it is a tough material having sufficient durability for general use in the bathroom. .

クッション材20は、表面材30の凹部31と基材11との間に設けられる。すなわち、クッション材20は、表面材30の凹部31の内部に格納された状態で、表面材30と基材11との間に挟み込まれる。   The cushion material 20 is provided between the recess 31 of the surface material 30 and the base material 11. That is, the cushion material 20 is sandwiched between the surface material 30 and the base material 11 in a state of being stored in the recess 31 of the surface material 30.

すなわち、凹部31の領域においては、基材11とクッション材20と表面材30とが積層される。一方、縁部32の領域においては、表面材30の縁部32と基材11との間には、クッション材20は介在せず、基材11と表面材30とが積層される。   That is, in the region of the recess 31, the base material 11, the cushion material 20, and the surface material 30 are laminated. On the other hand, in the region of the edge portion 32, the cushion material 20 is not interposed between the edge portion 32 of the surface material 30 and the base material 11, and the base material 11 and the surface material 30 are laminated.

すなわち、クッション材20の直上に、表面材30の薄肉部31aが積層され、クッション材20が積層されていない基材11の直上に、表面材30の厚肉部32aが積層される。   That is, the thin portion 31a of the surface material 30 is laminated directly on the cushion material 20, and the thick portion 32a of the surface material 30 is laminated directly on the base material 11 on which the cushion material 20 is not laminated.

クッション材20には、弾性変形可能であり、例えばウレタン等の発泡体等を用いることができる。すなわち、クッション材20は、基材11及び表面材30よりも弾性変形し易い。   The cushion material 20 can be elastically deformed, and for example, a foam such as urethane can be used. That is, the cushion material 20 is more easily elastically deformed than the base material 11 and the surface material 30.

表面材30の凹部31は、可撓性を有する程度の厚みで形成されているため、基材11とクッション材20と表面材30とが積層された浴室用洗い場床1aの床面は、使用者に軟らかい感触を与えることができる。   Since the concave portion 31 of the surface material 30 is formed with a thickness that has flexibility, the floor surface of the bathroom wash floor 1a in which the base material 11, the cushion material 20, and the surface material 30 are laminated is used. A soft feel can be given to the person.

一方、シール部50は、壁パネル80と表面材30の縁部32との間を水密的に塞ぐ。 シール部50には、例えばシリコーンなどの常温硬化型の液状樹脂や、硬質な目地材が用いられる。   On the other hand, the seal portion 50 watertightly seals between the wall panel 80 and the edge portion 32 of the surface material 30. For the seal portion 50, for example, a room-temperature curable liquid resin such as silicone or a hard joint material is used.

壁パネル80は、洗い場床の周囲に設けられるものであり、基材11及び縁部32の少なくともいずれかの直上に立設される。   The wall panel 80 is provided around the washing floor and is erected immediately above at least one of the base material 11 and the edge portion 32.

このような構成の浴室用洗い場床1aによれば、例えば、基材11にクッション材20を格納するための凹部を形成する必要がなく、基材11の浴室側の面(上面)は、例えば平坦にすることができる。従って、このような基材11は、図1に例示したように、クッション材20と表面材30とをその上に積層して、積層構造の浴室用洗い場床1aとしても利用できるし、例えば、クッション材20や表面材30を積層せず、単層の浴室用洗い場床にも利用できる。   According to the bathroom washroom floor 1a having such a configuration, for example, there is no need to form a recess for storing the cushioning material 20 in the base material 11, and the surface (upper surface) of the base material 11 on the bathroom side is, for example, It can be flat. Therefore, as illustrated in FIG. 1, such a base material 11 can be used as a bathroom wash floor 1a having a laminated structure by laminating a cushion material 20 and a surface material 30 thereon, for example, The cushion material 20 and the surface material 30 are not laminated, and can be used for a single-layer bathroom washroom floor.

例えば、基材11とクッション材20と表面材30とを積層した浴室用洗い場床1aは、ソフト感を持った床となる。もし、このような基材11を単層で用いた場合には、ソフト感を有さないハード床として、基材11が利用可能となる。   For example, the bathroom wash floor 1a in which the base material 11, the cushion material 20, and the surface material 30 are laminated is a floor having a soft feeling. If such a base material 11 is used in a single layer, the base material 11 can be used as a hard floor having no soft feeling.

そして、浴室用洗い場床1aにおいては、基材11及び縁部32の少なくともいずれかの直上に立設される壁パネル80と、表面材30の縁部32と、の間は、シール部50によって水密的に塞がれる。   And in the bathroom washroom floor 1a, between the wall panel 80 erected immediately above at least one of the base material 11 and the edge part 32 and the edge part 32 of the surface material 30, a seal part 50 is used. It is closed watertight.

この時、壁パネル80は、表面材30の厚肉部32aである縁部32と対向する。   At this time, the wall panel 80 faces the edge portion 32 which is the thick portion 32 a of the surface material 30.

例えば、図2に例示したように、浴室用洗い場床1aにおいては、壁パネル80が基材11の直上に立設している。すなわち、基材11の側壁部12の内側の壁パネル載置部13の上に、壁パネル80が載置される。そして、壁パネル80の浴室内側の側面と、表面材30の縁部32(厚肉部32a)の上面と、にシール部50が形成される。表面材30の縁部32(厚肉部32a)は、凹部31(薄肉部31a)よりも上下方向の変形が小さいので、壁パネル80と縁部32と間のシールに外力が加わりにくい。これにより、壁パネルと表面材との間のシール切れを防止できる。   For example, as illustrated in FIG. 2, the wall panel 80 is erected directly above the base material 11 in the bathroom washing floor 1 a. That is, the wall panel 80 is placed on the wall panel placement portion 13 inside the side wall portion 12 of the base material 11. And the seal | sticker part 50 is formed in the side surface inside the bathroom of the wall panel 80, and the upper surface of the edge part 32 (thick part 32a) of the surface material 30. FIG. Since the edge portion 32 (thick portion 32a) of the surface material 30 is less deformed in the vertical direction than the recess portion 31 (thin portion 31a), it is difficult for external force to be applied to the seal between the wall panel 80 and the edge portion 32. Thereby, the seal breakage between the wall panel and the surface material can be prevented.

また、表面材30に設けられた凹部31にクッション材20が格納されるため、基材11と表面材30との間にクッション材20が挟み込まれることに起因した応力が、表面材30へ加えられることがない。このため、表面材30と基材11との接着に悪影響を与えることがなく、表面材30と基材11との接着強度は高い。これにより、表面材と基材との間のシール切れを防止できる。   Further, since the cushion material 20 is stored in the concave portion 31 provided in the surface material 30, stress caused by the cushion material 20 being sandwiched between the base material 11 and the surface material 30 is applied to the surface material 30. It is never done. For this reason, the adhesion between the surface material 30 and the substrate 11 is not adversely affected, and the adhesion strength between the surface material 30 and the substrate 11 is high. Thereby, a seal break between the surface material and the base material can be prevented.

このように、浴室用洗い場床1aによれば、積層構造と単層構造の両方に利用でき、壁パネルと表面材との間や表面材と基材との間のシール切れを防止できる浴室用洗い場床が提供できる。   Thus, according to the bathroom washroom floor 1a, it can be used for both a laminated structure and a single-layer structure, and can be used for bathrooms that can prevent seal breakage between a wall panel and a surface material or between a surface material and a base material. A washroom floor can be provided.

また、図3に例示したように、変形例の浴室用洗い場床1bにおいては、壁パネル80が基材11の直上に立設し、壁パネル80の下部と、表面材30の縁部32と、の間に隙間がある。この場合には、壁パネル80の下部の側面と、表面材30の厚肉部32aの側面と、が対向する。この場合には、壁パネル80の下部の側面と、表面材30の厚肉部32aの上面及び側面と、にシール部50が形成される。これにより、シール部50が壁パネル80及び縁部32に接触する面積が、浴室用洗い場床1aよりも拡大し、壁パネル80と縁部32と間の水密的な封止の強度はさらに高められる。   Further, as illustrated in FIG. 3, in the bathroom washing floor 1 b of the modified example, the wall panel 80 is erected directly above the base material 11, and the lower portion of the wall panel 80 and the edge portion 32 of the surface material 30. There is a gap between them. In this case, the lower side surface of the wall panel 80 and the side surface of the thick portion 32a of the surface material 30 face each other. In this case, the seal portion 50 is formed on the side surface of the lower portion of the wall panel 80 and the upper surface and the side surface of the thick portion 32a of the surface material 30. As a result, the area where the seal portion 50 contacts the wall panel 80 and the edge portion 32 is larger than that of the bathroom washing floor 1a, and the strength of the watertight seal between the wall panel 80 and the edge portion 32 is further increased. It is done.

また、図4に例示したように、別の変形例の浴室用洗い場床1cにおいては、壁パネル80が縁部32の直上に立設している。この場合には、壁パネル80の下面と、表面材30の厚肉部32aの上面と、が対向する。この場合には、壁パネル80の側面と、表面材30の縁部32の上面と、にシール部50が設けられる。縁部32は、薄肉部31aよりも強度が高いので、シール部50による、壁パネル80と縁部32と間の水密的な封止の強度は高い。   Further, as illustrated in FIG. 4, in the bathroom washing floor 1 c of another modified example, the wall panel 80 is erected directly above the edge portion 32. In this case, the lower surface of the wall panel 80 and the upper surface of the thick portion 32a of the surface material 30 face each other. In this case, the seal portion 50 is provided on the side surface of the wall panel 80 and the upper surface of the edge portion 32 of the surface material 30. Since the edge portion 32 has higher strength than the thin-walled portion 31a, the strength of watertight sealing between the wall panel 80 and the edge portion 32 by the seal portion 50 is high.

また、図5に例示したように、別の変形例の浴室用洗い場床1dにおいては、壁パネル80が縁部32の直上に立設し、壁パネル80の下部に凹部がある。この場合には、壁パネル80の下面及び凹部と、表面材30の厚肉部32aの上面と、が対向する。この場合には、壁パネル80の下部の側面及び凹部と、表面材30の縁部32の上面と、にシール部50が設けられる。この場合もシール部50が設けられる縁部32の強度が高いので、壁パネル80と縁部32と間の水密的な封止の強度は高く、さらに、壁パネル80の下部の凹部にもシール部50が設けられ、シール部50と壁パネル80との接触面積が拡大し、さらに強度が高まる。   Further, as illustrated in FIG. 5, in the bathroom washing floor 1 d of another modified example, the wall panel 80 is erected directly above the edge portion 32, and there is a recess at the lower portion of the wall panel 80. In this case, the lower surface and the concave portion of the wall panel 80 and the upper surface of the thick portion 32a of the surface material 30 face each other. In this case, the seal portion 50 is provided on the lower side surface and the concave portion of the wall panel 80 and the upper surface of the edge portion 32 of the surface material 30. Also in this case, since the strength of the edge portion 32 where the seal portion 50 is provided is high, the strength of watertight sealing between the wall panel 80 and the edge portion 32 is high, and further, the seal is provided in the concave portion below the wall panel 80. The part 50 is provided, the contact area between the seal part 50 and the wall panel 80 is increased, and the strength is further increased.

なお、上記の浴室用洗い場床1b〜1dにおいても、表面材30に設けられた凹部31にクッション材20が格納され、表面材30へ応力が加えられることがないので、表面材30と基材11との接着強度は高い。   In the bathroom washing floors 1b to 1d described above, the cushion material 20 is stored in the recess 31 provided in the surface material 30, and no stress is applied to the surface material 30, so the surface material 30 and the base material The adhesive strength with 11 is high.

さらに、上記の浴室用洗い場床1a〜1dにおいては、表面材30に設けられた凹部31の内部にクッション材20が格納されるため、表面材30の上面は、段差のない面状にすることができる。すなわち、凹部31の上面(基材11とは反対の側の面)と、縁部32の上面(基材11とは反対の側の面)と、は連続した面である。
これにより、使用者に違和感を与えることがない。
Furthermore, in the bathroom washroom floors 1a to 1d described above, the cushion material 20 is stored inside the recess 31 provided in the surface material 30, and therefore, the upper surface of the surface material 30 should be a flat surface without a step. Can do. That is, the upper surface of the recess 31 (the surface on the side opposite to the base material 11) and the upper surface of the edge portion 32 (the surface on the side opposite to the base material 11) are continuous surfaces.
As a result, the user does not feel uncomfortable.

ここで、連続した面とは、凹部31と縁部32との境界において、表面材30の上面(基材11とは反対の側の面)に段差がないことを指す。そして、表面材30の上面に、例えば、洗い場床に溜まった水を排水するための各種の形状の溝などが設けられていた場合にも、凹部31の上面と縁部32の上面とは連続した面であり、段差がなければ良い。また、洗い場床に溜まった水を排水するために、洗い場床に傾斜が設けられ、この傾斜に従って表面材30の上面が傾斜を有していても良い。   Here, the continuous surface means that there is no step on the upper surface of the surface material 30 (the surface on the side opposite to the substrate 11) at the boundary between the recess 31 and the edge 32. And also when the groove | channel of various shapes for draining the water collected on the washing-room floor etc. was provided in the upper surface of the surface material 30, the upper surface of the recessed part 31 and the upper surface of the edge part 32 are continuous. It is good if there is no step. Moreover, in order to drain the water collected on the washing ground floor, the washing ground floor may be provided with an inclination, and the upper surface of the surface material 30 may have an inclination according to the inclination.

図6に表したように、変形例の浴室用洗い場床1eにおいては、凹部31の底面と、縁部32の底面とは、下方に向けて拡開した傾斜部によって繋がっている。すなわち、表面材30の凹部31凹部31は、凹部31の開口部の側に向けて(すなわち、下方に向けて)、拡開している。これ以外は、浴室用洗い場床1aと同様である。なお、縁部32の底面は、基材11に対向する側の面であり、縁部32の下面である。   As shown in FIG. 6, in the bathroom washing floor 1 e of the modified example, the bottom surface of the recess 31 and the bottom surface of the edge portion 32 are connected by an inclined portion that expands downward. That is, the recess 31 of the surface material 30 is expanded toward the opening of the recess 31 (that is, downward). Except this, it is the same as the bathroom wash floor 1a. The bottom surface of the edge portion 32 is a surface on the side facing the substrate 11 and is the lower surface of the edge portion 32.

すなわち、凹部31の側面には、凹部31の下面(基材11に対向し、基材11に対して平行な面)に対して傾斜した傾斜部31sが設けられている。なお、縁部32の下面(基材11に対向し、基材11に対して平行な面)は、凹部31の下面と実質的に平行なので、凹部31の側面の傾斜部31sは、縁部32の下面に対して傾斜している。   That is, the side surface of the recess 31 is provided with an inclined portion 31 s that is inclined with respect to the lower surface of the recess 31 (a surface facing the base material 11 and parallel to the base material 11). In addition, since the lower surface of the edge portion 32 (a surface facing the base material 11 and parallel to the base material 11) is substantially parallel to the lower surface of the concave portion 31, the inclined portion 31s on the side surface of the concave portion 31 is an edge portion. It is inclined with respect to the lower surface of 32.

具体的には、凹部31の開口部の広さが、凹部31の奥に行くに従って小さくなるような傾斜部31sを、凹部31(薄肉部31a)と縁部32(厚肉部32a)との境界に設ける。   Specifically, the inclined portion 31 s such that the width of the opening of the concave portion 31 becomes smaller as it goes deeper into the concave portion 31, and the concave portion 31 (thin portion 31 a) and the edge portion 32 (thick portion 32 a). Provide at the boundary.

このように、厚肉部32aと薄肉部31aの間を傾斜状にすることで、表面材30の厚さが急激に変化しないため、表面材30の外観不良(ヒケ等の成形不良)が起きにくい。また、表面材30のピンスポットに集中負荷がかかることがないため、耐久性にも優れる。   Thus, since the thickness of the surface material 30 does not change abruptly by making the space between the thick wall portion 32a and the thin wall portion 31a, an appearance defect of the surface material 30 (molding defects such as sink marks) occurs. Hateful. Moreover, since concentrated load is not applied to the pin spot of the surface material 30, it is excellent also in durability.

また、厚肉部32aでは床表面が相対的に硬く、薄肉部31aではクッション材20によって床表面が相対的に軟らかくなるが、傾斜部31sを設けることで、この硬い部分と軟らかい部分との境界が緩やかに変化するため、使用者は違和感を得にくい。もし、厚肉部32aと薄肉部31aとの境界が傾斜状でなく、垂直状である場合には、この境界に当たると違和感を得、特に車椅子などで洗い場床の上を移動した際に顕著となる。これに対し、浴室用洗い場床1dのように厚肉部32aと薄肉部31aとの境界に傾斜部31sを設けることで、この違和感を低減することができる。
なお、傾斜部31sは、図6のように直線状に傾斜するものだけではなく、曲線状に傾斜するものも含む。
Further, the floor surface is relatively hard in the thick portion 32a, and the floor surface is relatively soft due to the cushion material 20 in the thin portion 31a, but the boundary between the hard portion and the soft portion is provided by providing the inclined portion 31s. Changes slowly so that the user is less likely to get a sense of incongruity. If the boundary between the thick wall portion 32a and the thin wall portion 31a is not inclined but is vertical, it will give a sense of incongruity when hitting this boundary, especially when moving over the washing floor with a wheelchair or the like. Become. On the other hand, this discomfort can be reduced by providing the inclined part 31s at the boundary between the thick part 32a and the thin part 31a as in the bathroom washing place floor 1d.
Note that the inclined portion 31s includes not only a linearly inclined portion as shown in FIG. 6 but also a curvedly inclined portion.

なお、表面材30の凹部31の傾斜部31sと、基材11と、の間の空間にもクッション材20を挿入しても良い。これにより、厚肉部32aと薄肉部31aとの境界における違和感をさらに低減することができる。なお、この場合には、クッション材20の周縁部には、凹部31の傾斜部31sの傾斜に沿うような傾斜を設けることができ、これにより、クッション材20は、表面材30の凹部31と基材11との間の空間に、この空間からはみ出すことなく、また表面材30に応力を加えることなく、格納できる。   The cushion material 20 may be inserted into the space between the inclined portion 31 s of the concave portion 31 of the surface material 30 and the base material 11. Thereby, the uncomfortable feeling in the boundary of the thick part 32a and the thin part 31a can further be reduced. In this case, the peripheral edge portion of the cushion material 20 can be provided with an inclination along the inclination of the inclined portion 31 s of the concave portion 31, so that the cushion material 20 is connected to the concave portion 31 of the surface material 30. It can be stored in the space between the base material 11 without protruding from this space and without applying stress to the surface material 30.

なお、このように表面材30の凹部31の側面の傾斜部31sは、上記の浴室用洗い場床1b〜1dのいずれかの場合にも設けることができ、同様の効果を発揮する。   In addition, the inclined part 31s on the side surface of the recess 31 of the surface material 30 can be provided in any of the above-described bathroom washing floors 1b to 1d, and exhibits the same effect.

(実施例)
本実施形態に係る実施例の浴室用洗い場床について説明する。
図7に表したように、実施例に係る浴室用洗い場床1fにおいては、基材11の上に、凹部31(薄肉部31a)を有する表面材30が積層され、凹部31と基材11との間の空間にクッション材20が挟み込まれて積層されている。表面材30の凹部31の周辺の縁部32(厚肉部32a)において、基材11と表面材30とは接着されている。
(Example)
The bathroom wash floor of the example according to this embodiment will be described.
As shown in FIG. 7, in the bathroom washing floor 1 f according to the example, the surface material 30 having the recess 31 (thin portion 31 a) is laminated on the base 11, and the recess 31, the base 11, A cushion material 20 is sandwiched and stacked between the spaces. The base material 11 and the surface material 30 are bonded to each other at the edge portion 32 (thick wall portion 32 a) around the concave portion 31 of the surface material 30.

そして、基材11の周縁において、側壁部12の内側の壁パネル載置部13の上に、壁パネル80が立設される。
そして、シール部50は、壁パネル80と縁部32との間を水密的に塞ぐ。
A wall panel 80 is erected on the wall panel mounting portion 13 inside the side wall portion 12 at the periphery of the base material 11.
The seal portion 50 seals between the wall panel 80 and the edge portion 32 in a watertight manner.

本具体例では、基材11の側壁部12の内側に、側壁部12に沿って内側壁部12aが設けられ、側壁部12と内側壁部12aとの間が、壁パネル載置部13となる。壁パネル80の下部の外側の側面は基材11の側壁部12に密着している。一方、壁パネル80の下部の内側の側面と、基材11の内側壁部12aと、の間は離間しており、この間には、シールの補助剤となる発泡性の充填剤51が充填される。そして、表面材30の縁部32と、壁パネル80の下部の側面と、の間に、シール部50が埋め込まれる。シール部50は、充填剤51を覆うように設けられる。   In this specific example, an inner wall portion 12a is provided along the side wall portion 12 on the inner side of the side wall portion 12 of the base material 11, and the space between the side wall portion 12 and the inner wall portion 12a is the wall panel mounting portion 13 and Become. The outer side surface of the lower portion of the wall panel 80 is in close contact with the side wall portion 12 of the substrate 11. On the other hand, the inner side surface of the lower part of the wall panel 80 and the inner wall portion 12a of the base material 11 are separated from each other, and a foamable filler 51 serving as a sealing auxiliary agent is filled between them. The Then, the seal portion 50 is embedded between the edge portion 32 of the surface material 30 and the lower side surface of the wall panel 80. The seal part 50 is provided so as to cover the filler 51.

一方、基材11の一方の端には、上方に突出した土手部15が設けられている。そして、表面材30は、土手部15に沿うように設けられ、上方に延在する立ち上がり部33を有している。この立ち上がり部33は、クッション材20が格納される凹部31よりも外側にあり、立ち上がり部33は、縁部32の一部と見なされる。   On the other hand, a bank portion 15 protruding upward is provided at one end of the base material 11. And the surface material 30 is provided along the bank part 15, and has the standing part 33 extended upwards. The rising portion 33 is located outside the concave portion 31 in which the cushion material 20 is stored, and the rising portion 33 is regarded as a part of the edge portion 32.

表面材30の凹部31は、薄肉部31aであり、この部分にクッション材20が格納されている。凹部31は、凹部31の開口部に向けて拡開している。すなわち、凹部31には傾斜部31sが設けられている。   The concave portion 31 of the surface material 30 is a thin-walled portion 31a, and the cushion material 20 is stored in this portion. The recess 31 is expanded toward the opening of the recess 31. That is, the recessed portion 31 is provided with an inclined portion 31s.

そして、表面材30の上面は段差がない。すなわち、凹部31の上面(基材11とは反対の側の面)と、縁部32の上面(基材11とは反対の側の面)と、は連続した面である。   And the upper surface of the surface material 30 does not have a level | step difference. That is, the upper surface of the recess 31 (the surface on the side opposite to the base material 11) and the upper surface of the edge portion 32 (the surface on the side opposite to the base material 11) are continuous surfaces.

そして、シール部50は、土手部15の立ち上がり面と、表面材30における土手部15に沿った立ち上がり部33の端部と、の間に配置される。すなわち、シール部50は、土手部15と縁部32との間を水密的に塞いでいる。この場合も、下層にクッション材20が積層された部分とは異なる部分において、表面材30と基材11との水密的な封止が行われるので、シール切れを防止できる。   The seal portion 50 is disposed between the rising surface of the bank portion 15 and the end portion of the rising portion 33 along the bank portion 15 in the surface material 30. That is, the seal portion 50 closes the space between the bank portion 15 and the edge portion 32 in a watertight manner. Also in this case, since the watertight sealing between the surface material 30 and the base material 11 is performed in a portion different from the portion where the cushion material 20 is laminated in the lower layer, it is possible to prevent the seal from being cut.

これにより、浴室用洗い場床1fにおいては、積層構造と単層構造の両方に利用でき、壁パネルと表面材との間や表面材と基材との間のシール切れを防止できる。   Thereby, in the bathroom washroom floor 1f, it can be used for both the laminated structure and the single-layer structure, and seal breakage between the wall panel and the surface material or between the surface material and the base material can be prevented.

図8は、実施例の浴室用洗い場床1fに設けられる排水口の部分を部分的に例示している。図8に例示したように、浴室用洗い場床1fの排水口8に対応して、基材11には排水口部18が設けられている。排水口部18には、排水口トラップ40が取り付けられる。そして、基材11の排水口部18の上に、表面材30の垂下部38が積層されている。表面材30の垂下部38の厚さは、縁部32の厚さよりも薄い。これにより、垂下部38が基材11の排水口部18の形状に沿って位置合わせされることが容易になる。   FIG. 8 partially illustrates a portion of a drain outlet provided in the bathroom wash floor 1f of the embodiment. As illustrated in FIG. 8, the base material 11 is provided with a drain port portion 18 corresponding to the drain port 8 of the bathroom washroom floor 1 f. A drain trap 40 is attached to the drain port 18. A drooping portion 38 of the surface material 30 is laminated on the drain port portion 18 of the base material 11. The thickness of the drooping portion 38 of the surface material 30 is smaller than the thickness of the edge portion 32. This makes it easy for the drooping portion 38 to be aligned along the shape of the drain port portion 18 of the base material 11.

一方、図7に例示したように、基材11の土手部15に沿って設けられる表面材30の立ち上がり部33における厚さは、縁部32における厚さよりも薄い。これにより、立ち上がり部33が柔軟になり、立ち上がり部33が基材11の土手部15の形状に適合し易くなり、立ち上がり部33と土手部15とにおける基材11と表面材30との接着強度が向上する。そして、立ち上がり部33と土手部15とが位置合わせされ、表面材30と基材11との位置合わせが容易となる。   On the other hand, as illustrated in FIG. 7, the thickness of the rising portion 33 of the surface material 30 provided along the bank portion 15 of the base material 11 is smaller than the thickness of the edge portion 32. Thereby, the rising part 33 becomes flexible, the rising part 33 is easily adapted to the shape of the bank part 15 of the base material 11, and the adhesive strength between the base material 11 and the surface material 30 at the rising part 33 and the bank part 15. Will improve. Then, the rising portion 33 and the bank portion 15 are aligned, and alignment of the surface material 30 and the base material 11 becomes easy.

このように、本実施形態に係る浴室用洗い場床においては、クッション材20を格納する凹部31の周りに縁部32が設けられ、凹部31の厚さが縁部32の厚さよりも薄ければ良く、例えば、上記の垂下部38や立ち上がり部33のように、排水口8の部分や、縁部32のさらに外側において、厚さが薄い部分が表面材30に設けられても良い。   Thus, in the bathroom washroom floor according to the present embodiment, if the edge portion 32 is provided around the recessed portion 31 for storing the cushion material 20 and the thickness of the recessed portion 31 is thinner than the thickness of the edge portion 32. For example, as in the hanging portion 38 and the rising portion 33 described above, a portion with a small thickness may be provided on the surface material 30 on the portion of the drain port 8 or on the outer side of the edge portion 32.

(第2の実施の形態)
図9に表したように、第2の実施形態に係る浴室用洗い場床2aも、基材11と表面材30とクッション材20とシール部50とを備える。
(Second Embodiment)
As shown in FIG. 9, the bathroom washing floor 2 a according to the second embodiment also includes the base material 11, the surface material 30, the cushion material 20, and the seal portion 50.

浴室用洗い場床2aにおける基材11は、土手部15を有している。土手部15は、洗い場側と浴槽側とを区切るための上方に突出した部分である。そして、この場合も、基材11は、硬質な材料で形成される。   The base material 11 in the bathroom wash floor 2a has a bank portion 15. The bank portion 15 is a portion protruding upward for separating the washing area side and the bathtub side. Also in this case, the base material 11 is formed of a hard material.

そして、浴室用洗い場床1aと同様に、基材11とクッション材20と表面材30とが積層される。すなわち、表面材30は、縁部32(厚肉部32a)と、縁部32よりも内側に設けられ、基材11に対向する側が後退した凹部31(薄肉部31a)と、を有する。表面材30は、縁部32において、基材11と接着されている。そして、クッション材20は、表面材30の凹部31と基材11との間に設けられる。   And the base material 11, the cushioning material 20, and the surface material 30 are laminated | stacked similarly to the washroom floor 1a for bathrooms. That is, the surface material 30 includes an edge portion 32 (thick wall portion 32a) and a recess portion 31 (thin wall portion 31a) that is provided on the inner side of the edge portion 32 and whose side facing the base material 11 is retracted. The surface material 30 is bonded to the base material 11 at the edge portion 32. The cushion material 20 is provided between the concave portion 31 of the surface material 30 and the base material 11.

そして、シール部50は、基材11の土手部15と、表面材30の縁部32との間を水密的に塞ぐ。   And the seal part 50 watertightly seals between the bank part 15 of the base material 11 and the edge part 32 of the surface material 30.

このような構成の浴室用洗い場床2aにおいても、基材11にクッション材20を格納するための凹部を形成する必要がなく、基材11の上面は、例えば平坦にすることができる。これにより、基材11は、積層構造の浴室用洗い場床2aとしても利用できると同時に、単層構造の浴室用洗い場床にも利用できる。   Even in the bathroom washing floor 2a having such a configuration, it is not necessary to form a recess for storing the cushion material 20 in the base material 11, and the upper surface of the base material 11 can be made flat, for example. Thereby, the base material 11 can be used also as a bathroom washroom floor 2a having a laminated structure, and at the same time, can also be used for a bathroom washroom floor having a single layer structure.

また、浴室用洗い場床2aにおいては、土手部15の側面と、表面材30の縁部32(厚肉部32a)の上面と、にシール部50が形成される。表面材30の縁部32(厚肉部32a)は、凹部31(薄肉部31a)よりも上下方向の変形が小さいので、土手部15と縁部32と間の水密的な封止の強度は高い。これにより、基材11の土手部15と表面材との間のシール切れを防止できる。   Moreover, in the bathroom wash floor 2a, the seal portion 50 is formed on the side surface of the bank portion 15 and the upper surface of the edge portion 32 (thick wall portion 32a) of the surface material 30. Since the edge portion 32 (thick portion 32a) of the surface material 30 is less deformed in the vertical direction than the concave portion 31 (thin portion 31a), the strength of the watertight sealing between the bank portion 15 and the edge portion 32 is high. Thereby, the seal breakage between the bank portion 15 of the base material 11 and the surface material can be prevented.

そして、この場合も、表面材30に設けられた凹部31にクッション材20が格納されるため、基材11と表面材30との間にクッション材20が挟み込まれることに起因した応力が、表面材30へ加えられることがないため、表面材30と基材11との接着強度は高い。これにより、表面材と基材との間のシール切れを防止できる。   Also in this case, since the cushion material 20 is stored in the recess 31 provided in the surface material 30, the stress caused by the cushion material 20 being sandwiched between the base material 11 and the surface material 30 is caused by Since it is not added to the material 30, the adhesive strength between the surface material 30 and the substrate 11 is high. Thereby, a seal break between the surface material and the base material can be prevented.

また、図10に例示したように、変形例の浴室用洗い場床2bにおいては、土手部15と、表面材30の縁部32と、の間に隙間がある。そして、土手部15の側面と、表面材30の縁部32(厚肉部32a)の側面と、が対向する。この場合には、土手部15の側面と、表面材30の縁部32の上面及び側面と、にシール部50が形成される。従って、土手部15及び縁部32に接触するシール部50の面積がより拡大し、土手部15と縁部32と間の水密的な封止の強度はさらに高められる。   Further, as illustrated in FIG. 10, in the bathroom washing floor 2 b of the modified example, there is a gap between the bank portion 15 and the edge portion 32 of the surface material 30. And the side surface of the bank part 15 and the side surface of the edge part 32 (thick part 32a) of the surface material 30 oppose. In this case, the seal portion 50 is formed on the side surface of the bank portion 15 and the upper surface and the side surface of the edge portion 32 of the surface material 30. Therefore, the area of the seal portion 50 that contacts the bank portion 15 and the edge portion 32 is further increased, and the strength of watertight sealing between the bank portion 15 and the edge portion 32 is further increased.

なお、既に説明したように、縁部32は、土手部15に沿って立ち上がった立ち上がり部33を有することができる。そして、図7に例示した浴室用洗い場床1fのように、シール部50は、土手部15と、縁部32の一部である立ち上がり部33と、の間を水密的に塞ぐように配置されることができる。これにより、下層にクッション材20が積層された部分とは異なる部分において、表面材30と基材11との水密的な封止が行われるので、シール切れを防止できる。   As already described, the edge portion 32 can have a rising portion 33 that rises along the bank portion 15. Then, like the bathroom washing floor 1f illustrated in FIG. 7, the seal portion 50 is disposed so as to block water tightly between the bank portion 15 and the rising portion 33 that is a part of the edge portion 32. Can. Thereby, since the watertight sealing of the surface material 30 and the base material 11 is performed in a portion different from the portion where the cushion material 20 is laminated in the lower layer, it is possible to prevent the seal from being cut.

(第3の実施の形態)
図11に表したように、第3の実施形態に係る浴室用洗い場床3aも、基材11と表面材30とクッション材20とシール部50とを備える。

The surface material 30 is provided on the base material 11. The surface material 30 includes an edge portion 32 and a recess portion 31 provided on the inner side of the edge portion 32 and having a surface on the side facing the base material 11 formed in a concave shape with respect to the edge portion 32. In the edge portion 32, the surface material 30 is bonded to the base material 11. The cushion material 20 is provided between the base material 11 and the recess 31. The seal part 50 hydrates the space between the water return part 14 and the edge part 32.

なお、本実施形態においても、基材11、表面材30、クッション材20及びシール部50には、既に説明した材料を適用できる。   In the present embodiment, the already described materials can be applied to the base material 11, the surface material 30, the cushion material 20, and the seal portion 50.

図12に表したように、基材11の周縁に設けられる水返し部14は、例えば、基材11の中央部の上面よりも上方に立ち上がった第1壁部14aと、第1壁部14aよりも外側において、略水平方向に延在する壁パネル載置部14bと、壁パネル載置部14bの外側において、壁パネル載置部14bの上面よりも上方に立ち上がった第2壁部14cと、を有する。そして、壁パネル載置部14bの上に壁パネル80が載置される。   As shown in FIG. 12, the water return part 14 provided in the periphery of the base material 11 includes, for example, a first wall part 14a and a first wall part 14a rising above the upper surface of the central part of the base material 11. A wall panel mounting portion 14b extending in a substantially horizontal direction on the outer side, and a second wall portion 14c rising above the upper surface of the wall panel mounting portion 14b on the outer side of the wall panel mounting portion 14b. Have. And the wall panel 80 is mounted on the wall panel mounting part 14b.

そして、本具体例では、水返し部14の一部である第1壁部14aの側壁と、表面材30の縁部32とが、シール部50によって水密的に塞がれている。シール部50は、少なくとも、水返し部14と、縁部32と、の間に配置される。すなわち、シール部50は、少なくとも、水返し部14と縁部32との間の隙間を覆うように設けられる。   In this specific example, the side wall of the first wall portion 14 a that is a part of the water return portion 14 and the edge portion 32 of the surface material 30 are watertightly closed by the seal portion 50. The seal part 50 is disposed at least between the water return part 14 and the edge part 32.
