Description

  The present invention relates to a bathroom washroom floor formed mainly of foamed resin.

Patent Document 1 discloses a first cushion layer formed of foamed polypropylene or the like having an expansion ratio of 6 to 10 on a high-hardness floor pedestal in order to give a soft comfortable feeling to a bathroom floor. And a second cushion layer molded from foamed polyurethane having a foaming ratio of 4.0 to 4.5 times, and further higher than the second cushion layer in order to give durability to the washing surface. Disclosed is a bathroom washroom floor constructed with an advanced surface layer. This first cushion layer is foam-molded in a mold to shape the shape of the floor base material (see Patent Document 2). According to this method, while using an inexpensive mold, it is possible to provide a washing floor that imparts a soft treading comfort that cannot be obtained with a conventional FRP (fiber reinforced plastic) washing floor.
However, since this washing floor has the shape of the floor base material formed by foam molding, it cannot be manufactured with high accuracy and has a larger tolerance than press molding or the like.

  On the other hand, as shown in Patent Document 3, a washroom floor is provided in which a surface material made of a resin sheet having a concavo-convex pattern is placed on the upper surface of a floor divided into a side floor and a center floor.

  In manufacturing a washing floor floor that gives a soft stepping feeling as shown in Patent Document 1 described above, a split floor as shown in Patent Document 3 (the floor of Patent Document 3 is the same as that of Patent Document 1). If it is tried to apply (corresponding to the first cushion layer), a floor base material which is a foam molded product cannot be formed with high precision, and there is a large tolerance, so a step may be generated between adjacent floor base materials. is there. In that case, in order to give a soft comfortable feeling, a highly flexible polyurethane cushion layer provided between the surface layer and the floor base material is flexible. It is easy to be intimate so as to adapt to the level difference between the materials. Therefore, while a soft stepping feeling can be obtained, when the level difference generated between the floor base materials is large, it is easy to feel the level difference when stepping on and the stepping feeling is deteriorated.

  Furthermore, the upper surface of the washroom floor is provided with a drainage gradient that slopes downward toward the drain outlet. Therefore, even if the floor base material is covered with the cushion layer and the surface layer, if the level difference between the floor base materials is large, the level difference between the floor base materials appears on the upper surface of the washing floor, and the drainage gradient A concave portion that accumulates water is formed on the way, drainage performance is significantly deteriorated, and it takes a long time for the washing floor to dry.

  Therefore, the present invention aims to solve the above-mentioned problems and to obtain a bathroom washroom floor that can maintain the drainage performance of the washroom floor while making the floor base material formed by foaming resin into a split type. And

  In order to solve the above-described problems, in the bathroom washroom floor according to claim 1, a support body having a floor base material composed of a plurality of face material constituent members made of foamed resin and a floor support surface for supporting the floor base material. And a surface material constituting the upper surface of the washing area, and a cushion material disposed between the floor base material and the surface material, and a bathroom provided with a drainage gradient that slopes downward toward the drain outlet A plurality of the face material constituting members are formed on the line connecting the outer peripheral end and the drain outlet so as to approach the drain outlet as the distance from the outer peripheral end of the upper surface of the wash floor increases. It is characterized by being divided into two.

According to this, even if a level difference occurs between adjacent surface material component members due to molding errors that occur in the foam-molded surface material component members, the level difference increases in the drain outlet as the distance from the outer peripheral edge of the upper surface of the washing area increases. It is formed so as to approach and appears on a line connecting the outer peripheral end and the drain. Since the line continuously inclines downward toward the drain, even if a level difference between the face material components appears on the surface of the washing area, the water flowing on the washing area flows along the line and drains. Flows into the mouth. For this reason, no recess is formed on the upper surface of the washing floor where water accumulates.
Therefore, it is possible to provide a bathroom washroom floor that can maintain a good drainage performance of the washroom floor while making the floor base material formed by foaming the resin into a split type.

  According to a second aspect of the present invention, the drainage gradient is formed by a plurality of drainage gradient surfaces having different gradient directions, and the line is formed by intersecting two drainage gradient surfaces adjacent to each other among the plurality of drainage gradient surfaces. It is arranged below the valley line.

According to this, a level | step difference does not arise in the middle of the inclination of a waste_water | drain gradient, and the recessed part which water accumulates on the upper surface of a washing-room floor is not formed. Therefore, the water on the washing ground flows to the drain outlet along the valley line formed by the intersection of the two drain slope surfaces.
Therefore, the water on the washing place can be quickly poured into the drain outlet.

  Moreover, in Claim 3, the frame material in which the groove part which mounts the wall of a bathroom was formed is arrange | positioned along the outer periphery of the said floor base material.

  According to this, although the vicinity of the groove part which mounts the wall of a bathroom becomes a complicated shape, the part is made into a different body from a face material component. Therefore, the cost for producing the mold can be further reduced.

  Moreover, in Claim 4, the said face material structural member and the said drainage gradient surface are made into the same shape by planar view.

  According to this, since the face material constituting member can be uniformly inclined in one direction, it is possible to further reduce the cost for producing a foam mold.

  ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to obtain the washroom floor of the bathroom which can maintain the drainage performance of a washroom floor favorably, making the floor base material which carried out resin foam molding into the split type.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a bathroom having a washing floor according to the first embodiment, and FIG. 2 is an exploded perspective view showing the washing floor.

  As shown in FIG. 1, the bathroom unit includes a washing floor 1, a bathtub 6 adjacent to the washing floor 1, and a wall 7 installed so as to surround the washing floor 1 and the bathtub 6. The wall 7 is fitted in a groove formed in the outer peripheral end 1c of the washing floor 1. A drain outlet 151 is provided at the end of the washing floor 1 on the bathtub side. Further, a water blocking wall 1 b is provided on the bathtub side of the washing floor 1, and a bath apron 9 is provided on the washing area side of the bathtub 6.

  Below the washing floor 1, a drain pipe 8 is laid to communicate the drain port 151 with a drain pipe outside the bathroom.

  As shown in FIG. 2, the washroom floor 1 includes a support 11, a floor base material 12, a cushion material 13, a surface material 14, and a drain port member 15 that forms a drain port 151.

The support 11 includes a frame 111 having legs 112 and a reinforcing member 115 fixed to the upper surface of the frame 111. The frame 11 is configured in a steel ladder shape. A material having high strength and rigidity is suitable for the reinforcing member 115. As an example, a sandwich panel in which a resin plate is sandwiched between steel plates or a deck plate formed by bending a steel plate is used. The upper surface of the reinforcing member 115 serves as a floor support surface 115 a that supports the floor base material 12.
The reinforcing member 115 includes a hole (not shown) surrounding the drain port member 15. In addition, a work port 115h for work such as height adjustment of the legs 112 at the time of construction is provided in the approximate center of the reinforcing member 115. After the work is finished, the work port 115h is covered with a lid 116.

  The floor base material 12 is obtained by foaming a resin, is formed of foamed polypropylene having a foaming ratio of 6 to 10 times, and includes a floor surface portion 121 and a standing wall portion 123. Further, a surface material fixing portion 121a to which the end portion of the surface material 14 is bonded is formed at the peripheral edge portion of the floor surface portion 121, and the cushion material 13 is embedded inside the surface material fixing portion 121a. A recess 121b is formed. The cushion material incorporating recess 121 b includes a hole (not shown) surrounding the drain port member 15. In addition, on the upper surface of the cushion material built-in recess 121b, a gradient is provided that serves as a basis for a drainage gradient that is inclined toward the drain port member 15.

  The cushion material 13 is made of foamed polyurethane having a foaming ratio of 4.0 to 4.5 times, and has higher elasticity and flexibility than the floor base material 12. This cushion material 13 is embedded and bonded in a cushion material built-in recess 121b formed in the floor base material 12. Further, the cushion material 13 includes a notch 13 h surrounding the drain port member 15.

The surface material 14 has a floor surface portion 141 that covers the floor surface portion 121 of the floor base material 12 and forms the surface of the washing place 1a. Moreover, the skin material 14 has the standing wall surface part 142 which covers the standing wall part 122 of the floor base material 12, and forms the surface of the water stop wall 1b in an edge part. The surface material 14 includes a hole 14 h that surrounds the drain port member 15. The surface material 14 covers the surfaces of the floor base material 12 and the cushion material 13 and is bonded to the surface material fixing portion 121 a of the floor base material 12.
The surface material 14 is provided with a drainage groove (not shown) for slowly discharging the water remaining on the washing place 1a to the drainage port member 15 without being interrupted. Thereby, the drainage performance is improved so that water remaining on the washing place 1a when taking a bath at night is almost disappeared from the washing place 1a on the next day.

  The drain port member 15 has a concave shape that forms the drain port 151. The drain port member 15 is connected to the lower surface of the surface material 14 around the hole 14h.

Next, the drainage gradient provided on the upper surface of the washing place 1a will be described.
FIG. 3 is a schematic diagram showing a drainage gradient applied to the washing floor.
As shown in FIG. 3, a drainage gradient is provided on the upper surface of the washing place 1 a in order to allow the water on the washing place 1 a to flow to the drain port member 15. As described above, this drainage gradient is based on the gradient provided in the cushion material incorporating recess 121b of the floor base 12. The drainage gradient is divided into three drainage gradient surfaces 161, 162, and 163 that are descending toward the drain port member 15. Each of the drainage gradient surfaces 161 to 163 is a flat surface, and is uniformly inclined downward from each side of the outer peripheral end portion 1c of the washing place 1a toward the drain port member 15.

A plurality of arrows S1 shown in FIG. 3 represent the downward gradient directions of the drainage gradient surfaces 161 to 163 formed in the washing place 1a. That is, the direction in which the arrow S1 points indicates the downward direction. As described above, in the washing place 1a, the drainage gradient surfaces 161 to 163 are inclined from the sides of the outer periphery of the washing place 1a to the direction perpendicular to each side, that is, the inclined plane inclined downward toward the drain port member 15. It has become.
Due to such a drainage gradient, the water on the washing place 1 a is discharged to the drain port member 15.

Among the drainage gradient surfaces 161 to 163, an arbitrary drainage gradient surface and a drainage gradient surface adjacent to the drainage gradient surface, that is, adjacent drainage gradient surfaces have different gradients, and thus have two drainage gradients. The boundary between the faces is a valley line. A boundary M1 ₁₂ between the drainage gradient surface 161 and the drainage gradient surface 162 is a valley line inclined toward the drainage port member 15. Further, a boundary M1 ₂₃ between the drainage gradient surface 162 and the drainage gradient surface 163 is a valley line inclined toward the drainage port member 15. When a single drainage gradient surface has two boundaries, the two boundaries are separated from each other by a predetermined distance and are connected to the drain port member 15. Therefore, the drainage gradient surfaces 161 to 163 are not in contact with the drain port member 15 at a point, but in contact with each other in a plan view. For example, the drainage gradient surface 162 has two boundaries M1 ₁₂ and M1 ₂₃ , and these boundaries M1 ₁₂ and M1 ₂₃ are connected to the drain port member 15 at a distance from each other, so that the drainage gradient surface 162 is separated from the boundary M1. in the end surface 162a connecting the ₁₂ and the boundary _{M1 23} articulating the discharge port member 15. When one drainage gradient surface has only one boundary, the end surface sandwiched between the boundary of the drainage gradient surface and the end surface of the drainage gradient surface on the opposite side to the boundary contacts the drainage port member 15 on the surface. . For example, the drainage slope surface 161 connected to the drainage port member 15 in the end face 161a that connects the boundary _{M1 12} and the end surface 161b.

  Therefore, the water flowing on the drainage gradient surface always passes over the end surface on the drainage port member 15 side of the drainage gradient surface and flows into the drainage port member 15 (the drainage gradient surface 161 passes over the end surface 161a. The drainage gradient surface 162 passes over the end surface 162a and flows into the drainage port member 15).

Next, the configuration of the floor base material 12 will be described in more detail.
FIG. 4 is a schematic view showing a floor base material of a washing floor, (a) is a plan view showing a state in which the floor base material is divided into a plurality of face material constituting members and a frame material, and (b) is a plurality of faces. It is a top view which shows the state which isolate | separated the material structural member and the frame material.
As shown in FIG. 4, the floor base 12 is configured by gathering together a plurality of face member constituting members 121, 122, 123 and frame members 127 a, 127 b, 127 c, 127 d and integrating them with a connecting member (not shown). Has been.

  The face material constituting members 121 to 123 are all provided with a slope inclined downward toward the drain port member 15. These face material constituting members 121 to 123 are obtained by foaming a resin. Therefore, it cannot be manufactured with high accuracy and has a relatively large tolerance. Therefore, the height difference of the face material constituting members 121 to 123 may occur due to tolerance. When a difference in height occurs between the face material constituting members, there is a step between the adjacent face material constituting member 121 and the face material constituting member 122, and between the face material constituting member 122 and the face material constituting member 123. It will occur.

However, in the floor base material 12 of the present embodiment, when the floor base material 12 is configured by the plurality of face material constituent members 121 to 123, the drain base member 15 approaches the drain port member 15 as the distance from the outer peripheral end 1c of the upper surface of the washing place 1a increases. And is divided into a plurality of face member constituting members 121 to 123 by lines L1 ₁₂ and L1 ₂₃ connecting the outer peripheral end 1c and the drain port member 15. Therefore, even if a step is generated between the face member constituting members 121 to 123, the step is provided along the lines L1 ₁₂ and L1 ₂₃ from the outer peripheral end 1c of the washing place 1a to the drain port member 15. Become. Since the lines L1 ₁₂ and L1 ₂₃ are inclined downward toward the drain port member 15, the step between the face member constituting members is also continuously inclined downward from the outer peripheral end 1c toward the drain port member 15. Will be provided. Thereby, even if a step is generated between the face material constituting members 121 to 123 in this washing place 1a, the step does not block the drainage gradient of the washing place 1a, and a recess that allows water to accumulate on the washing place by the step. Never formed. Therefore, it becomes possible to keep the drainage performance of the washing place 1a favorable.

FIG. 5 is a schematic perspective view showing a drainage gradient between the face member constituting members in FIG. 4. However, the face material constituting member 121 is formed larger than the face material constituting member 122, and a step is generated between the face material constituting member 121 and the face material constituting member 122.
According to the washing place floor 1 of the present embodiment, even if this step appears on the surface of the washing place 1a, the direction in which the steps are connected is provided along the line L1 ₁₂ . As described above, since the line L1 ₁₂ is inclined downward toward the drain port member 15, the level difference between the face member constituting member 121 and the face member constituting member 122 is also changed from the outer peripheral end 1c to the drain port member 15. Inclined continuously downward. Thereby, in this washing place 1a, even if a level | step difference arises between the surface material structural members 121-123, the drainage gradient of the washing place 1a is not interrupted by this level | step difference, and water accumulates on the washing place 1a by the level | step difference. A recess is not formed.

Next, comparative examples will be described in order to help understanding of the operational effects of the present embodiment.
6A and 6B are schematic views showing a floor base material as a comparative example, where FIG. 6A is a plan view of the floor base material, and FIG. 6B is a YY cross-sectional view of FIG.
In the washing place 2a of this comparative example, the lines L2 ₁₂ and L2 ₂₃ that divide the plurality of face material constituting members 221 to 223 are provided so as to connect the outer peripheral end portions 2c of the washing place 2a to each other, and the outer peripheral end portion 2c. And the drain port member 15 are not connected. Further, the lines L2 ₁₂ and L2 ₂₃ cross M2 ₁₂ and M2 ₂₃ on the drainage gradient surface. And the face material component 221 disposed at a position farther from the drain port member 15 is larger than the face material component 222 disposed near the drain port member 15. When formed, the step occurring between the face plate component 221 and the face material component 222, a surface material constituting member 221 side of the line L2 ₁₂ is a step to be low. Then, the surface material constituting member 221 side of the line L2 _12, a recessed portion 1e so as to divide the middle of the drainage slope occurs, the water collected in the recess 1e no longer be discharged into the discharge port member 15. That is, in the washing place 2a of this comparative example, the drainage performance of the washing place 2a cannot be kept good.

On the other hand, in the washing place 1a of this embodiment, the floor base material 12 made of foamed resin with a drainage gradient is formed so as to approach the drain port member 15 as the distance from the outer peripheral end 1c of the upper surface of the washing place 1a increases. On the lines L1 ₁₂ and L1 ₂₃ connecting the end portion 1c and the drain port member 15, the face member constituting members 121 to 123 are divided. As a result, even if a step is generated between the adjacent face member constituent members due to the molding error generated in the foam-formed face member constituting members 121 to 123, the step appears on the lines L1 ₁₂ and L1 ₂₃ . Since the lines L1 ₁₂ and L1 ₂₃ are continuously inclined downward toward the drain port member 15, even if a step is generated between the face member constituting members, the water flowing on the washing place is the lines L1 ₁₂ and L1 _23. And flows into the drain port member 15. For this reason, no recess is formed on the upper surface of the washing place 1a where water accumulates. Therefore, it is possible to provide the washing place floor 1 that can maintain the drainage performance of the washing place 1a well while making the floor base material 12 formed by foaming the resin into a split type.

FIG. 7 is a cross-sectional view showing the outer peripheral edge of the washing floor.
In the floor base material 12 of the present embodiment, the frame members 127a to 127d in which the groove portions 1d on which the walls 7 are placed are arranged along the outer periphery of the face member constituting members 121 to 123. According to this, the vicinity of the groove portion 1d having a complicated shape can be separated from the face material constituting members 121 to 123, and the cost for manufacturing the mold can be further reduced.

Next, a modified example of the floor base material will be described. Note that in the embodiments described below including this modification, the same reference numerals are given to the same configurations as those in the above-described embodiments, and the description thereof is omitted.
8A and 8B are diagrams showing a floor base material of a washing place floor according to a modification, wherein FIG. 8A is a perspective view showing the washing place, and FIG. 8B divides the floor base material into a plurality of face material constituting members and frame materials The top view which shows the state which carried out, (c) is a top view which shows the state which isolate | separated the some surface material structural member and frame material.

In the washing place 3a, three drainage gradient surfaces 161 to 163 having different gradient directions are formed by the floor base material 12 in which the three surface material constituting members 321 to 323 are arranged. A line L3 ₁₂ between the face material constituting member 321 and the face material constituting member 322 is disposed below the boundary M3 ₁₂ between the drainage gradient surfaces of the washing place 3a, and the face material constituting member 322 and the face material constituting member 323 are connected to each other. An intervening line L3 ₁₂ is disposed below the boundary M3 ₂₃ between the drainage gradient surfaces of the washing place 3a. That is, the lines L3 ₁₂ and L3 ₂₃ are disposed below the valley lines M3 ₁₂ and M3 ₂₃ formed by the intersection of two adjacent drainage gradient surfaces among the plurality of drainage gradient surfaces 161 to 163.
Therefore, the face material constituting members 321 to 323 and the drainage gradient surfaces 161 to 163 have the same shape in plan view. Further, the face member constituting members 321 to 323 are separated from the frame members 127a to 127d in which the groove portions 1d on which the walls 7 are placed are formed.

  According to this, since the face material constituting members 321 to 323 can be formed into a simple shape that is uniformly inclined in one direction, it is possible to further reduce the cost for producing a foam molding die. .

  According to this modification, there is no step in the middle of the slope of the drainage gradient, and no recess is formed on the upper surface of the washing place 3a so that water accumulates. Therefore, the water on the washing ground flows to the drain port member 15 along the valley line formed by the intersection of the two drain slope surfaces. Therefore, the water on the washing place can be quickly poured into the drain port member 15.

Next, the washing floor according to the second embodiment of the present invention will be described.
FIG. 9: is a figure which shows the waste_water | drain gradient provided to the washing place floor concerning 2nd embodiment, (a) is a perspective view which shows a washing place, (b) is a floor base material with several face material component members. The top view which shows the state divided | segmented into the frame material, (c) is a top view which shows the state which isolate | separated the some surface material structural member and frame material.
In the first embodiment, the drainage gradient surfaces 161 to 163 are inclined planes in which the downward gradient toward the drain port member 15 is uniformly inclined in each region, but in the second embodiment, The washing place 4 a has a drainage gradient as a curved drainage gradient surface 46 having a mortar-shaped gradient that slopes downward toward the drainage port member 15. Therefore, in this washing place 4a, there is no boundary formed by a plurality of drainage gradient surfaces having different gradient directions.

  The floor base material 42 of the washing floor 4 has a mortar-shaped gradient that slopes downward toward the drain port member 15, similarly to the drain gradient surface 46. Further, the floor base material 42 is divided into a face material constituting member 421 and a face material constituting member 422 obtained by foam molding of a resin.

In this floor base material 42, when the floor base material 42 is constituted by the face material constituting members 421 and 422, the floor base material 42 is formed so as to approach the drain port member 15 as it is away from the outer peripheral end portion 4c of the upper surface of the washing place 4a, and by a line _{L4 12} connecting the outer peripheral end portion 4c and the discharge port member 15 is divided into a plurality of face material components 421 and 422. Therefore, even when level difference between the face plate components 421 and 422, the level difference from the outer peripheral edge portion 4c of the washing area 4a up to the discharge port member 15 will be provided along a line L4 _12. Since the line L4 ₁₂ is inclined downward toward the drain port member 15, the step between the face material constituting members is also provided so as to continuously descend downward from the outer peripheral end 4c toward the drain port member 15. Will be. As a result, in this washing place 4a, even if a step is generated between the face material constituting members 421 and 422, the step does not block the drainage gradient of the washing place 4a, and there is a recess that allows water to accumulate on the washing place by the step. Never formed.
Therefore, also in the second embodiment, it is possible to maintain good drainage performance of the washing place 4a while dividing the floor base material 42 into a plurality of parts.
