Description

  The present invention relates to a bathroom washroom structure using foamed resin as a flooring material.

Bathroom made up of a floorboard made of inorganic material, a foamed plastic board placed on the floorboard, and a protective layer placed on the foamed plastic board in order to lighten the waterproofing pan for the bathroom washroom and make it easier to handle A waterproof floor pan is proposed (for example, Patent Document 1). This waterproof floor pan uses 10 times expanded polystyrene as a foamed plastic plate. Thus, since the waterproof floor pan described in Patent Document 1 is formed mainly of foamed plastic, it is possible to reduce the manufacturing cost.
However, since the waterproof floor pan described in Patent Document 1 uses 10-fold expanded polystyrene as the foamed plastic plate, the strength against the load is weak. For this reason, the waterproof floor pan was immediately deformed and the durability was poor. In addition, the wash floor in the bathroom has a drain slope that slopes toward the drain outlet on the surface, so if the waterproof floor pan is deformed, the predetermined drain slope cannot be maintained, and a puddle remains on the wash floor. The problem arises.

On the other hand, in order to make the user feel soft while having surface durability as a washroom floor, a support base layer for supporting a load and a cushion that is laminated on the support base layer and elastically deformable And a surface layer that is laminated on the cushion layer and has durability, and the surface layer has a thick part for ensuring strength and a thin part for imparting flexibility. A washroom floor has been proposed (for example, Patent Document 2). This cushion layer is sandwiched between the support base material layer when a load is applied on the surface layer and is subjected to compression deformation, and the amount of contraction with respect to the reference load at the time of the compression deformation is the first amount. A first cushion layer having a cushion layer and a second cushion amount that is smaller than the first amount (ie, harder than the second cushion layer) with respect to a reference load when being compressed and deformed; The cushion layer is disposed on the upper side and the second cushion layer on the lower side so as to overlap in the vertical direction. As the support base layer of the bathroom washroom floor, a thermosetting resin such as FRP (Fiber Reinforced Plastic) or a thermoplastic resin such as polypropylene or polyethylene reinforced can be used. Moreover, as a cushion layer, foams, such as urethane, can be used. As the surface layer, FRP, PVC (vinyl chloride), polypropylene, polyethylene, urethane resin, polyester resin, various elastomers of styrene / polyester / olefin / acrylic type, rubber (hard) type such as EVA, EPDM, silicone rubber, etc. Alternatively, a material prepared by adjusting the hardness to such an extent that sufficient durability can be expected, or a composite material obtained by adding a filler or a reinforcing material to the base can be used.
In the bathroom washroom floor described in Patent Document 2, since the cushion layer is laminated on the support base material layer and the surface layer is laminated on the cushion layer, the surface layer has durability. By doing so, it is possible to have the durability required as a bathroom washroom floor while having softness.

  However, the bathroom washroom floor described in Patent Document 2 has a high-strength support base material layer arranged immediately below the cushion layer, so that only the surface feels soft and the tread feel is further improved. There was room to do. In addition, although the cushion layer functions as a heat insulating layer, the support base layer immediately below the cushion layer is made of a thermosetting resin such as FRP or a reinforced resin obtained by reinforcing a thermoplastic resin. The heat of the cushion layer on the surface was easily taken away, and there was room for further improvement in the heat insulation of the washing floor.

Japanese Patent Application Laid-Open No. 11-343650 JP 2011-117140 A

  SUMMARY OF THE INVENTION In order to solve the above-described problems, an object of the present invention is to provide a bathroom wash floor having a step comfort that cannot be obtained by a conventional wash floor and high heat insulation.

  In order to solve the above-described problems, the present invention provides an adjuster leg installed on a building floor, a floor mount having a high hardness supported by the adjuster leg, and a floor pan placed on the floor mount. The floor pan has a lower hardness than the floor mount and is a foamed molded product made of a thermoplastic resin, and is placed so as to be in close contact with the floor pan support surface formed on the floor mount. A first cushion layer, a foamed resin molded product that is more flexible than the first cushion layer, the second cushion layer provided in close contact with the upper surface of the first cushion layer, and the second And a surface layer having a hardness higher than that of the second cushion layer, wherein the bathroom is in close contact with the upper surface of the cushion layer, and the upper surface is exposed to the surface of the washing place. Washing place It is.

According to this, the first cushion layer of the floor pan is provided with moderate flexibility. Therefore, when it is placed on the floor pan, it can feel a soft touch (stepping comfort) as if it were placed on a tatami mat. Such a feeling is completely new and comfortable for a bathroom washroom floor, which cannot be obtained with a floor pan provided with a single cushion layer on a conventional support base layer made of FRP.
Further, a second cushion layer softer than the first cushion layer is closely overlapped on the first cushion layer. Since the cushion layer on the side near the surface of the floor pan is a relatively soft layer, it is possible to soften the surface of the floor pan itself, so you can spend comfortably even sitting on the floor pan for a long time It becomes.
Moreover, since both the first cushion layer and the second cushion layer are foamed resin moldings, the heat insulating property is remarkably superior to the conventional one. Therefore, it is difficult for the heat of the floor pan to escape under the floor, and when it is placed barefoot on the floor pan, the surface of the floor pan can feel an unprecedented warmth.

The first cushion layer is made of foamed polypropylene having an expansion ratio of about 6 to 10 times, and the second cushion layer is made of foamed polyurethane having an expansion ratio of about 4.0 to 4.5 times. It is preferable.
With such a foaming ratio of the resin material, it is difficult to be deformed even when a load is applied to the washing floor, and it does not break during transportation, so that it is excellent in handleability and durability.
In addition, when the foaming ratio is too large, the foamed resin molded product deteriorates durability against concentrated load, and unevenness occurs on the surface of the floor pan. On the other hand, if the expansion ratio is reduced, the durability against concentrated load is improved. However, if the expansion ratio is too low, it tends to break. In contrast, in the present invention, the foaming ratio of the first cushion layer is about 6 to 10 times, and the foaming ratio of the second cushion layer is about 4.0 to 4.5 times. Both sexiness and resistance to breakage are good.

Furthermore, the first cushion layer can be formed thicker than the second cushion layer.
According to this, since the first cushion layer is thick, it is possible to give the first cushion layer strength as a floor pan, so it is excellent in transportability and also easy to assemble at the construction site. It will be excellent.

Furthermore, the floor gantry includes a steel plate deck plate formed into a corrugated shape so that a floor pan supporting surface that supports the floor pan and a non-supporting surface that does not support the floor pan are alternately arranged. When the person puts the difference in height between the floor pan supporting surface and the non-supporting surface on the floor pan placed on the deck plate, the lower surface of the first cushion layer faces downward on the unsupported surface. It is possible to make it larger than the bending dimension.
According to this, the floor pan is placed on a deck plate in which a plurality of steel plates are installed in parallel at intervals. Therefore, when the floor pan at a position between the steel plates is stepped on, the floor pan is deformed so as to sink slightly between the steel plates, and it becomes possible to feel softness. Further, the sinking of the floor pan between the steel plates can provide a unique and comfortable feel when walking barefoot on the floor pan.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to provide the washing-room floor of the bathroom which has the tread feeling which cannot be obtained with the conventional washing-room floor, and high heat insulation.

Embodiments of the present invention will be described below with reference to the drawings. In addition, in each drawing, the same code | symbol is attached | subjected to the same component and detailed description is abbreviate | omitted suitably.
FIG. 1 is a schematic perspective view showing a bathroom unit according to an embodiment of the present invention.
FIG. 2 is a schematic exploded view showing the floor gantry and the floor pan of the present embodiment.
FIG. 3 is a cross-sectional view of the floor mount 100.
FIG. 4 is a cross-sectional view showing a state in which the floor pan 200 is placed on the deck plate-type floor mount 100.

First, a bathroom unit assembled by the bathroom assembly method according to the present embodiment will be described with reference to the drawings.
The bathroom unit illustrated in FIG. 1 includes a floor gantry 100, a floor pan 200, a bathtub 300, a wall 400, and a door frame 500.

As shown in FIG. 1, the floor mount 100 is installed on the installation surface (for example, the floor of a building) of the bathroom installation space 10, receives a load applied to the upper surface of the floor pan 200, and maintains its position.
As shown in FIG. 2, the floor gantry 100 includes a floor gantry body 110 and a lid 130. The floor gantry main body 110 has adjuster legs 111 having a structure whose height can be adjusted by rotating the bolt portion, and supports the floor pan 200 from below. Then, the height of the floor gantry body 110 is adjusted by the adjuster legs 111, so that the horizontal surface of the floor pan 200 is secured.

  As described above, since the floor gantry 100 receives a load applied to the upper surface of the floor pan 200, it needs a sufficient strength. For example, a steel deck plate is used as the upper part of the floor mount 100. The upper surface of the floor gantry 100, that is, the upper surface of the deck plate is a vertical reference position of each member included in the floor pan 200 and the bathtub 300, that is, a horizontal reference surface.

  A work port (opening) 113 penetrating in the vertical direction is provided at the center of the floor base body 110. For example, an operator who performs assembly work in the bathroom adjusts the height of the support legs 111 by inserting his hand from the work port 113 and reaching the lower side of the floor gantry 100, or drains water on the back side of the floor gantry 100. Pipes can be arranged and connected easily. Then, after adjusting the height of the support leg 111 or arranging or connecting the drain pipe, the work port 113 is closed by the lid 130.

  A drain trap 180 is attached to the floor base body 110 so as to straddle the bathtub side floor base.

The floor pan 200 is placed on the floor base body 110 of the floor base 100.
The floor pan 200 is mainly formed of a thermoplastic foam resin. Examples of the thermoplastic foamed resin include foamed polypropylene, foamed polyethylene, and foamed polyurethane. Since the thermoplastic foamed resin is recyclable, the use of this makes it possible to reduce CO2 emissions associated with the manufacture and disposal of the floor pan 200 and provide an environmentally friendly product. In addition, the foamed resin can reduce the mold cost as compared with other molding methods, and can provide a bathroom at a lower price than the conventional one.
The floor pan 200 is made of a thermoplastic resin, is formed in a shallow vessel shape (bread shape) whose peripheral portion is bent upward, and has a waterproof property that prevents water from leaking out of the bathroom. In addition, a mounting portion on which the wall 400 and the door frame 500 are mounted is provided around the surface (surface) of the floor pan 200 opposite to the floor mount 100. Similarly, around the bathtub 300, a placement portion on which the wall 400 is placed is provided.

  As shown in FIG. 2, in the floor pan 200, a drainage part 210 communicating with the drainage pipe is formed in the vicinity of the boundary with the bathtub 300. The portion where the drainage unit 210 is provided is recessed, and the surface of the floor pan 200 is provided with a drainage gradient inclined downward toward the drainage unit 210. A packing 221, a washer 223, and a tightening flange 225 for clamping the drain trap 180 and the drain unit 210 to sandwich the floor mount 100 and the floor pan 200 are attached to the drain unit 210.

  As illustrated in FIG. 1, the wall 400 constitutes four surfaces of the bathroom unit and includes first to seventh wall panels 410 to 470 which are wall materials. Between adjacent wall panels, wall surface connection members (joiners) 405 that connect the adjacent wall panels to each other are erected on the outer periphery of the floor pan 200 and the outer periphery of the bathtub 300. The wall surface connecting member 405 is held by a wall surface fixing member (joiner mounting portion) described in detail later.

Next, the floor pan 200 will be described in detail.
As shown in FIG. 3, the floor pan 200 includes a first cushion layer 201, a second cushion layer 202, and a surface layer 203.

  The first cushion layer 201 is a foamed molded product of a thermoplastic resin having a lower hardness than the floor gantry body 110. Specifically, the first cushion layer 201 is a foamed molded product made of polypropylene having a foaming ratio of about 6 to 10 times, and is a floor pan support surface (floor pan mounting surface) formed on the floor frame 100. Surface) is placed in close contact with 110A.

  The second cushion layer 202 is a foamed molded product made of polyurethane foam that is more flexible than the first cushion layer 201. More specifically, the second cushion layer 202 has a foaming ratio smaller than that of the first cushion layer 201 and about 4.0 to 4.5 times, and is a foamed resin that is more flexible than the first cushion layer 201. It is a molded product. The second cushion layer 202 is provided in close contact with the upper surface of the first cushion layer 201.

  Then, a surface layer 203 whose upper surface is exposed to the surface of the washing place is provided so as to be in close contact with the surface of the second cushion layer 202. The surface layer 203 has a higher hardness than the second cushion layer 202.

The second cushion layer 202 is formed to a thickness of about 4 mm. The surface layer 203 is formed to a thickness of about 2 mm.
On the other hand, the first cushion layer 201 has a thickness larger than the thickness of the second cushion layer 202 and the surface layer 203 overlapped. Specifically, the thickness of the outer peripheral end of the first cushion layer 201 is 25 mm, and the thickness of the thinnest part near the drainage part 210 is 10 mm.

As shown in FIG. 4, the floor pan 200 is placed on the floor pan placement surface of the floor gantry 100.
The floor gantry body 110 of the floor gantry 100 includes a floor pan support surface 110A (floor pan placement surface) on which the floor pan 200 is placed and supports the floor pan 200, and an unsupported surface 110B on which the floor pan 200 is floating. Are provided with a deck plate formed by bending the steel plate 110C into a corrugated shape so that they are alternately arranged in parallel. The upper surface of the corrugated upper portion of the steel plate 110C is the floor pan support surface 110A (floor pan placement surface).
And the space | interval of adjacent floor pan support surface 110A is about 40 mm, and is not too wide. Therefore, the floor pan support surface 110 </ b> A and the non-support surface 110 </ b> B have dimensions that the lower surface of the first cushion 201 is deformed downward when the floor pan 200 is bent by a person being placed on the floor pan 200. The difference in height is also large.

As described above, in the washing floor according to the present embodiment, the first cushion layer 201 of the floor pan 200 is harder and thicker than the second cushion layer 202, and thus has appropriate flexibility. . Therefore, when it is placed on the floor pan 200, it is possible to feel a soft touch (step comfort) as if it were placed on a tatami mat. Such a feeling is a completely new feeling for a bathroom washroom floor, which cannot be obtained with a floor pan provided with a single cushion layer on a conventional support base layer made of FRP.
A second cushion layer 202 that is softer than the first cushion layer 201 overlaps the first cushion layer 201 in close contact. Since the cushion layer on the side close to the surface of the floor pan 200 is a relatively soft layer, the surface itself of the floor pan 200 can be softened, so that it can be comfortably spent sitting on the floor pan 200 for a long time. It becomes possible.
Moreover, since both the 1st cushion layer 201 and the 2nd cushion layer 202 are foamed resin moldings, heat insulation is also much more excellent than before. Therefore, the heat of the floor pan 200 is difficult to escape under the floor, and when it is placed barefoot on the floor pan 200, the surface of the floor pan 200 can feel an unprecedented warmth.
Furthermore, the floor pan 200 capable of providing a touch (treading comfort) that is not conventionally provided is placed on a deck plate in which a plurality of floor pan support surfaces 110A are installed in parallel at intervals. Therefore, when the floor pan 200 at a position between the floor pan support surfaces 110A is stepped on, the floor pan 200 is deformed so as to sink slightly between the floor pan support surface 110A and the adjacent floor pan support surface 110A, Furthermore, it becomes possible to feel softness. The sinking of the floor pan 200 between the floor pan support surfaces 110A makes it possible to obtain a unique and comfortable feel when walking barefoot on the floor pan 200.

Next, a modified example of the floor mount will be described.
FIG. 5 is a cross-sectional view showing a state where the floor pan 200 is placed on the sandwich panel main body 110 having a sandwich panel shape.
In this modification, a sandwich panel formed by sandwiching a filler such as a resin plate between two steel plates is used as the floor gantry body 110 of the floor gantry 100. This sandwich panel type floor mount is lighter than that formed entirely of steel, but has sufficient rigidity to support the floor pan 200.
The upper surface of the floor gantry 100, that is, the upper surface of the sandwich panel is a vertical reference position of the floor pan 200, that is, a horizontal reference surface.
The floor pan 200 is placed on the upper surface of the sandwich panel. Therefore, the floor pan 200 is stably supported.

  In the washing floor of this modification, the floor gantry body 110 is not a deck plate, so the floor pan 200 is not deformed so as to sink between the floor pan support surfaces 110A. The softness of the can not be felt, but a new feel like that placed on a tatami can be sufficiently obtained.

The embodiment of the present invention has been described above. However, the present invention is not limited to these descriptions. As long as the features of the present invention are provided, those skilled in the art appropriately modified the design of the above-described embodiments are also included in the scope of the present invention.
For example, instead of a deck plate-type floor gantry body, a floor gantry body in which a plurality of steel plates are arranged in parallel with a gap between them to form a floor pan support surface can be used.
