Abstract

PROBLEM TO BE SOLVED: To provide a bathroom structure which uses foamed plastics as a floor surface material, which dispenses with a dedicated member and construction, and which enables the floor surface material to easily and surely adhere to a floor base material.SOLUTION: A bathroom structure includes a floor holding member installed on a bathroom installation surface, a floor base material fixedly provided on the floor holding member, a floor surface material provided in the state of contact with a top surface of the floor base material and formed of foamed plastics, and a wall surface material forming a vertical wall surface of the bathroom. The wall surface material linearly pushes an outer edge of the floor surface material toward the floor base material.

Description

  An aspect of the present invention relates to a bathroom structure using foamed plastic as a flooring material for a bathroom.

  A bathroom structure using foamed plastic as a floor material constituting the floor surface of the bathroom is disclosed (Patent Document 1). In this bathroom structure, the washing area has a two-layer structure in which a floor material made of foamed plastic is placed on the bottom plate, and the bottom plate plays a role as a floor base material that bears the strength of the floor.

  In general, it is necessary to provide a drainage gradient in the washing area of the bathroom floor. However, in such a two-layer structure, a flat base plate that is easily available as a lower reinforcing layer is used for the reason of manufacturing. This drainage gradient may be provided on a floor material formed of an upper foamed plastic using a plate-like plate material. In that case, since the thickness of the floor surface material gradually decreases from the outer edge portion to the drain port portion, the floor surface material has a concave shape with the floor surface side as the inner surface as a whole.

  On the other hand, foamed plastics are usually molded into a desired shape by a method called foam molding, but the molding shrinkage rate is relatively large among the resin materials that are usually used, and it is adjusted according to molding conditions, etc. However, deformation called warping is likely to occur during molding. Such “warping” is particularly prominent when the thickness of the molded product is not uniform. For example, in the case of a concave shape, this concave shape is taken into account as a factor of “warping”, and the deformation toward the concave surface tends to be large, and this deformation may be a problem depending on the application.

  That is, when a concave floor surface material is formed by a foamed plastic molded product as in the example described in Patent Document 1, the floor surface material tends to have a large deformation that becomes concave on the floor surface side. As a result, when this floor material is placed on a flat bottom plate, the degree of adhesion between the surface of the bottom plate and the back surface of the floor material decreases, and if a person walks on the floor surface during use as it is You will feel rattling in the vertical direction. As a countermeasure, a method may be considered in which an adhesive is applied to the entire surface of at least one of the flooring material and the flooring base material, and the two layers are bonded and integrated. There arises a problem that the cost increases.

In this embodiment, the bath apron 9 also presses the floor material as described later, and is included in one of the wall materials of the present invention. Depending on the structure of the bathtub 1, there is a case where the bath apron 9 may not be provided.

FIG. 2 is a schematic exploded perspective view illustrating the configuration of the washing floor 2.
FIG. 3 is a schematic view for explaining the relationship between the washing floor 2 and the wall panel constituting the wall material in the present invention, FIG. 3 (a) is a schematic perspective view, and FIG. 3 (b) is FIG. 3 (a). It is a typical sectional view of an AA 'line arrow.
As illustrated in FIG. 2, the washing floor 2 includes a floor holding member 23, a floor base material 22, a floor surface material 21, a cushion material 201, and a skin material 202 in order from the bottom.

  The floor holding member 23 includes a support frame 232 that forms a support plane, and four support legs 231 provided at four corners of the support frame 232. The floor holding member 23 receives the entire load including the user of the bathroom on the upper surface of the washing floor 2 in the limited vertical space of the bathroom installation place, and holds the position thereof. Therefore, sufficient strength is required. Therefore, as an example of obtaining this sufficient strength, steel material is used in the present embodiment.

  The support legs 231 not only receive the load described above, but also have a structure that can be adjusted in height by rotating the bolt portion in order to level the wash floor 2.

  The support frame 232 includes, for example, two first frames 232a arranged in the first direction, and, for example, four second frames 232b arranged in a second direction orthogonal to the first direction. . The second frame 232b is disposed so as to connect between the two first frames 232a.

The floor base material 22 is placed on the support frame 232 and is fixed by a fastening member such as a screw. The floor base 22 is a horizontal reference plane whose upper surface serves as a vertical position reference for each member constituting the washing floor 2 and receives a load from a member placed thereon, and is supported. It is fixed to the frame 232. Therefore, a flat plate material having relatively high strength and rigidity is suitable for the floor base material 22, and a sandwich panel is used as an example. The sandwich panel has a structure in which, for example, a plastic plate material is sandwiched between two steel plates, and is a material that has high rigidity despite being relatively light and can be used with a fastening member such as a screw.
In addition, in the center of the floor base material 22, for example, a work opening is provided so that an operator can go under the floor for the leveling work of the floor base material 22 by adjusting the height of the support legs 231 during construction. 221h is provided. After the construction, the work port 221h is covered with a lid 221.

  The floor surface material 21 is placed on the floor base material 22 in contact with the back surface thereof, so that the floor surface material 21 is disposed on the basis of the surface (upper surface) of the floor base material 22. Become.

  The floor surface material 21 is formed of foamed plastic, and as will be described later, a three-dimensional shape such as a concave portion serving as a drain outlet and a sloped surface for forming a drainage gradient of the washing floor 2 and a water blocking wall at the outer edge. Is granted.

  For example, foamed polypropylene, foamed polystyrene, foamed polyethylene, and foamed polyurethane are used as the foamed plastic. In this embodiment, foamed polypropylene is used as an example. Foamed polypropylene is more recyclable than other foamed plastics, so using this makes it possible to provide environmentally friendly products.

  In the present embodiment, a skin material 202 is provided on the floor material 21 via a cushion material 201. All of these members are used to improve sensory performance such as appearance design and feeling of use of the floor surface of the washroom floor 2 and to improve functions inevitably required for the washroom floor 2 such as waterproofness. Yes.

  That is, the cushion material 201 obtains the softness of the floor surface given to the user. For example, a soft material such as foamed polyurethane is used. By changing the hardness (softness) of the cushion material 201, the specification of the hardness (softness) of the floor surface can be changed.

  The skin material 202 forms the surface of the washing floor 2, and a flexible soft sheet material having waterproofness is used. In order to improve the design and drainage properties of the surface of the washing floor 2, the skin material 202 can be subjected to uneven processing or a pattern.

  Each of these members is configured as a floor surface member that is an assembly in which the cushion material 201 and the skin material 202 are attached in advance to the surface of the floor surface material 21 before constructing the bathroom unit. Since the floor material 21 is formed of a lightweight foamed plastic, the construction work can be performed with sufficient lightness even if the assembly is configured in advance.

  FIG. 3 shows the relationship between the washing floor 2 and the wall 3 in the present embodiment. For convenience of explanation, the cushion material 201 and the skin material 202 described above are omitted in each figure. As shown in FIG. 3A, the floor material 21 is provided with a drain outlet 26 on one side in contact with the bathtub, and the surface has a water distribution gradient essential for the washing floor based on the drain outlet 26. Is provided. In addition, as will be described in detail later, the outer edge 21a has a shape necessary for a waterproof pan that is also used in a conventional washing floor, such as a recess into which a wall material is inserted and a standing wall that becomes a waterproof wall. It is formed as a groove in the present invention.

  Furthermore, as shown in FIG. 3B, the floor material 21 is provided in a state where the back surface is in contact with the surface of the floor base material 22 placed on the support frame 232.

  The outer edge portion 21a is pressed toward the floor base material 22 arranged on the back surface by the weight of the wall 3 which is a wall surface constituent member inserted into the groove portion formed on the front surface side. Specifically, the outer edge portion 21a corresponding to the three sides of the floor material 21 is pressed from the front surface side toward the back surface side by the first to third wall panels 31 to 33.

  As described above, in this embodiment, the basic structure of the floor surface of the washing floor 2 is a floor base material 22 that reinforces the strength required as a bathroom floor, and a floor that is placed on the floor base 22 and takes a necessary shape as a bathroom floor. By comprising with the face material 21, compared with the case where the FRP (Fiber Reinforced Plastics) material used conventionally is made into a basic structure, the effect which becomes a significant cost reduction as a bathroom floor is acquired.

  In other words, by forming the shape required for the bathroom floor with foamed plastic, in the mold forming that gives the shape using a mold that is large and expensive, compared with the molding using the FRP material that has been conventionally used. This makes it possible not only to greatly reduce the manufacturing cost of the molded product, but also to provide another required quality as a bathroom floor, mainly with a simple shape. It can be applied to a certain flat and inexpensive material.

  As a result, the weight of each component of the bathroom floor can be reduced, which not only facilitates construction work such as transportation and installation, but also greatly reduces the cost of manufacturing large bathroom floors. It becomes.

  Here, since the water distribution gradient is provided on the surface of the floor surface material 21 as described above, there is a difference in wall thickness between the outer edge portion 21a of the floor surface material 21 and the vicinity of the drain outlet 26, and the entire surface. From the perspective, the surface side is concave. For this reason, it has been confirmed by our experiments that the molded product of the floor material 21 tends to be deformed in a direction in which the surface side becomes further concave qualitatively. Then, when the floor material 21 in which such deformation has occurred is placed so as to be in contact with the surface of the floor base material 22, the floor surface material 22 is lifted at the outer edge portion 21 a of the floor surface material 21. It will be.

  Therefore, in this embodiment, the outer edge part 21a of the floor surface material 21 is pressed linearly by the wall 3 as described above. By doing so, when the wall 3 is assembled, it becomes possible to correct the concave deformation by causing the floor surface material 21 to follow the surface of the floor base material 22 by its own weight. In other words, in this embodiment, by utilizing a combination of the properties of deformation caused by warping that occurs qualitatively at the time of molding and the constituent members essential for the bathroom structure, separate processes such as adhesive application and only for fixing It is possible to easily and surely adhere the foamed plastic floor surface material 21 to the floor base material 22 to such an extent that no practical problem occurs without requiring any members.

4 and 5 are schematic enlarged cross-sectional views illustrating specific examples of the pressing structure of the floor surface material by the wall, and FIG. 4 shows the cushion material 201 and the skin material 202 employed in this embodiment. The example which implemented this invention in the structure which is not used is shown. FIG. 5 shows a detailed structure of a specific example in which the present invention is implemented in the configuration employed in the present embodiment using them.
In FIG. 4, for convenience of explanation, the same reference numerals are given to similar components corresponding to the present embodiment. In addition, although specific examples of the pressing structure for the portion of the first wall panel 31 are exemplified, the same applies to the portions of the second and third wall panels 32 and 33 and the small panel 37.

  In the specific example shown in FIG. 4A, the case where the outer edge portion of the floor surface material is directly pressed by the wall surface material is illustrated as in the present embodiment. In other words, the outer edge portion 21a of the floor surface material 21 has a recessed portion into which the wall surface material is inserted, a standing wall that becomes a waterproof wall, and the like, and a groove portion having a concave shape in cross section that forms a water stop structure for a connection portion with the bathroom floor surface 21b is provided, and the lower portion of the first wall panel 31 corresponding to the wall material is inserted into the concave portion of the groove portion 21b, and the lower end 31a abuts against the bottom surface of the concave portion. A caulking material CK is provided in the gap between the recess and the first wall panel 31 to prevent water in the bathroom from flowing around the back side of the wall panel 31.

  4 (b) and 4 (c) show specific examples in which one of the present inventions is applied and the part forming the groove 21b of the outer edge 21a is formed of a separate member. That is, the floor material 211 in this specific example is separated as a floor material frame 212 of a separate member at a portion corresponding to the groove 21b of the floor material 21 in this embodiment, and corresponds to the outer edge of the present invention. The floor surface material flange 211a having a flange shape on the outer peripheral portion is simply provided. 4 (b) and 4 (c), the horizontal positional relationship between the floor material brim 211a and the first wall panel 31 is different from each other. It is comprised so that it may become the form which presses 211a from upper direction.

  The floor material frame 212 is provided with a groove 21b having a concave shape in cross-sectional view as in the case of FIG. 4A described above, and the first wall panel 31 is inserted into the recess provided in the groove 21b. Is done. As a result, the lower end 31a of the first wall panel 31 abuts against the bottom surface of the recess of the floor material frame 212, and the floor material collar 211a of the floor material 211 is brought into contact with the floor base material 22 via the floor material frame 212. By being in a state of pressing toward the floor, it is possible to suppress the floating of the floor surface material flange 211a of the floor surface material 211 corresponding to the outer edge portion of the present invention.

  The groove portion 21b in these specific examples forms a water stop structure of a connecting portion where the lower end portion of the wall material is disposed, and this water stop structure is also required in the outer edge portion shape of a normal washing place floor. Therefore, the floor material frame 212 having this portion corresponds to the floor material frame of the present invention because it can be said to be a member necessary for constructing the normal washing place floor 2.

  Furthermore, by forming the groove portion 21b having a complicated shape essential to the washing floor 2 in the floor material frame 212 which is a separate member, the large floor material 211 does not have to have a complicated shape. Therefore, the floor material 211 and the floor material frame 212 can be formed by an optimum manufacturing method for each. Therefore, the floor surface material 211 can improve the moldability and precision as a floor surface material, compared with the case where it is formed by a single member.

  The floor material frame 212 may be made of the same foamed polypropylene as the floor material 21 or other foamed plastic. Furthermore, other materials such as general plastic materials may be used. In addition, the floor material frame 212 is further divided for each side of the floor material 21 within a range in which the shape is also required for the shape of the outer edge of a normal washing floor. In this case, an extruded product can be used. In those cases, the molding cost can be further reduced.

  FIG. 5A shows a detailed structure of a specific example employed in the present embodiment, and a cushion material 201 and a skin material 202 are placed on the surface (upper surface) of the floor surface material 21. ing. In this specific example, the first wall panel 31 has a steel plate 311 attached to the surface of a base material 310 such as a gypsum board for reinforcement. In this specific example, the outer edge portion 21 a of the floor surface material 21 is directly pressed by the steel plate 311 which is the lower end of the first wall panel 31.

The steel plate 311 is attached to, for example, the surface inside the bathroom of the base material 310, and is bent downward from the surface toward the lower end 310a. When the first wall panel 31 is erected, the bent portion 311 a of the steel plate 311 comes into contact with the bottom surface of the concave portion provided in the groove portion 21 b of the floor surface material 21. In a state where the first wall panel 31 is erected, a caulking material CK for waterproofing is provided in a gap between the recess and the steel plate 311 of the first wall panel 31.
In this way, by directly pressing the outer edge portion 21 a of the floor surface material 21 by the bent portion 311 a of the steel plate 311 constituting the wall panel 31, lifting of the outer edge portion 21 a of the floor surface material 21 can be suppressed.

  In the specific example shown in FIG. 5B, the present embodiment is that a packing PK corresponding to the pressing member in the present invention is provided between the bent portion 311a of the steel plate 311 and the bottom surface of the recess. In contrast, when the first wall panel 31 is erected, the bent portion 311a of the steel plate 311 is configured to indirectly press the outer edge portion 21a of the floor surface material 21 via the packing PK. Thus, the wall which is a wall surface material is provided by the packing PK which prevents the wraparound of the water from the inside of the bathroom to the outer surface side of the wall surface material via the contact portion with the floor surface material at the lower end of the wall surface material. Even when the panel 31 is erected in a slightly different state from the design, the rising of the outer edge portion 21a of the floor surface material 21 can be more reliably suppressed while absorbing the generated deviation.

  In the specific examples illustrated in FIGS. 5 (a) and 5 (b), the floor material 21 is formed as an integral member. However, FIGS. 4 (b) and 4 (c) show examples. As shown, the present invention can be applied even when the floor material frame 212 that forms the groove 21b, which is an essential shape on the floor, is divided and provided.

Next, the installation method of a wall panel is demonstrated.
In this embodiment, the wall panels 31-36 are mutually connected by the wall surface connection member in this invention which is a connection means, and form the wall 3 of a bathroom.
FIG. 6 is a schematic perspective view illustrating a wall surface connecting member, and illustrates a state where a plurality of wall surface connecting members 50 are attached to the outer peripheral portion 2 a of the washing floor 2. In this example, a total of five wall surface connection members 50 are attached by wall surface fixing members 51 to the central portion of the outer periphery 2a corresponding to each corner and long side of the outer periphery 2a.

FIG. 7 is a schematic perspective view illustrating the wall surface fixing member according to the present invention, which is an attachment member for fixing the wall surface connecting member 50 to the washing floor 2.
In the present embodiment, the wall surface fixing member 51 is a substantially L-shaped metal fitting, and is fixed to the floor base material 22 that is a member that forms the washing place floor 2 by fastening means such as bolts and screws.

FIG. 8 is a schematic cross-sectional view illustrating various attachment modes of the wall surface fixing member.
FIG. 8A is employed in the present embodiment, and shows a state in which the cushioning material 201 and the skin material 202 are not yet installed at the time when the wall panel has been assembled. In this attachment mode, the wall surface fixing member 51 is fixed to the floor base material 22 with screws or the like, and the wall surface connecting member 50 is fixed to the rising side 51a.
For example, a sandwich panel is used for the floor base material 22 and has a predetermined strength sufficient to support the wall panel, so that the wall surface fixing member 51 is firmly fixed.

  FIG. 8B shows another specific example. In this attachment mode, the wall surface fixing member 51 is fixed to the floor base material 22 and the support frame 232. That is, the floor base material 22 is fixed to the first frame 232a of the support frame 232 by fastening means such as screws. The wall surface fixing member 51 is fastened together with fastening means such as screws. The wall surface connecting member 50 is fixed to the rising side 51 a of the wall surface fixing member 51.

  FIG. 8C shows another specific example. In this mounting mode, the floor base material 22 is disposed inside the first frame 232a, and the wall surface fixing member 51 is attached to the first frame 232a. It is fixed. The floor base material 22 is disposed inside the first frame 232a, and the surface of the floor base material 22 is flush with the upper surface of the first frame 232a. That is, the first frame 232a is disposed at a position corresponding to the outer edge portion 21a of the floor surface material 21. Therefore, the wall surface fixing member 51 is directly fixed to the first frame 232a corresponding to the outer edge portion 21a. The wall surface connecting member 50 is fixed to the rising side 51 a of the wall surface fixing member 51.

8 (a) to 8 (c), the wall surface connecting member 50 is brought into contact with a part of the outer edge portion 21a of the floor surface material 21, thereby making the floor surface material 21 a floor base. When the wall surface connecting member 50 is attached to the wall surface fixing member 51 after being placed on the material 22, the floor surface material 21 is pressed downward by pressing the outer edge portion 21 a of the floor surface material 21 positioned by the lower end of the wall surface connecting member 50. May be temporarily fixed to the floor base material 22 at a plurality of locations.
Further, when the wall surface fixing member 51 is formed in an appropriate shape and the wall surface fixing member 51 is fixed, the outer edge portion 21 a of the floor surface material 21 may be fixed together by the wall surface fixing member 51.
As a result, when the bathroom is assembled, the floor material 21 is fixed in advance by the wall surface connection member 50 or the wall surface fixing member 51, so that the wall materials are connected to each other and inserted into the recesses of the groove 21 b of the floor surface material 21. As a result, the assembly work can be performed more easily and quickly.

FIG. 9 is a schematic cross-sectional view showing a fitting structure between a wall surface connecting member and a wall panel in the present embodiment.
In FIG. 9, the cross section along the direction orthogonal to the standing direction of the wall surface connection member 50 is shown.
Fig.9 (a) has illustrated the fitting structure of two wall panels adjacent on the same plane, and the wall surface connection member provided between these.
FIG. 9B illustrates a fitting structure of two wall panels that are orthogonal to each other at the corners and a wall surface connecting member provided therebetween.
In the following description, the wall surface connecting member 50A illustrated in FIG. 9A and the wall surface connecting member 50B illustrated in FIG. 9B are collectively referred to as the wall surface connecting member 50.

The wall surface connecting member 50 has a hollow structure in which a thin plate is bent, and the left and right folded portions 501 have a spring property.
FIG. 9A illustrates an attached state of the two wall panels 31-1 and 31-2 constituting the first wall panel 31. On the left and right side portions of the steel plates 311 of the two wall panels 31-1 and 31-2, back-back portions 502-1 and 502-2 with spring properties are provided, respectively.

In order to attach the two wall panels 31-1 and 31-2 to the wall surface connecting member 50A, the folded portions 502-1 and 502-2 are fitted between the left and right folded portions 501 of the wall surface connecting member 50A. The folded portions 502-1 and 502-2 are fitted so as to push and spread between the left and right folded portions 501.
When the folded portions 502-1 and 502-2 are fitted, the two wall panels 31-1 and 31-2 are fixed to the same surface with the wall surface connecting member 50A interposed therebetween.

FIG. 9B illustrates the mounting state of the first wall panel 31 and the second wall panel 32. However, the mounting state is different from FIG. 9A only in the mounting angle of the two wall panels. Since the basic structure adopts the same concept, the description is omitted.
When the folded portions 502-1 and 502-2 are fitted, the two wall panels 31 and 32 are fixed in a state orthogonal to each other with the wall surface connecting member 50A therebetween.

  As described above, the folded portion 501 of the wall surface connecting member 50 and the folded portions 502 of the wall panels 31 and 32 have spring properties in the plane (horizontal) direction orthogonal to the wall 3, so the installation positions of each other are The engagement is fixed and has a shape that regulates the position in the vertical direction and is freely movable. Therefore, when the wall panels 31 and 32 are fitted into the wall surface connection member 50, the wall panels 31 and 32 fall downward due to their own weight, and their lower ends (folded portions 311 a) abut against the concave portions of the groove portions 21 b of the outer edge portion 21 a of the floor surface material 21. Therefore, it becomes possible to press the outer edge portion 21a of the floor surface material 21 to the floor base material 22 linearly by the weight of the wall surface material, that is, almost all of the outer edge portion 21a. Thereby, the floor surface material 21 can be brought into close contact with the floor base material 22 in a state where the overall deformation of the concave shape of the floor surface material 21 is corrected.

  The wall panels 31 (31-1, 31-2) and 32 can be easily attached by fitting to the wall surface connecting member 50, and as described above, at the same time as this attachment, Since the outer edge portion 21a is pressed, it is not necessary to press the floor material 21 in a separate process.

FIG. 10 is a schematic perspective view illustrating an attached state of the bus apron.
The outer edge portion 21 a on the bathtub 1 side of the floor surface material 21 may be pressed by the bath apron 9.
As shown in FIG. 10, when attaching the bath apron 9, first, as shown by the arrow D shown in FIG. 10, the upper end portion of the bath apron 9 is inserted into the back side of the flange portion 1 a of the bathtub 1 from below. To do. Then, the lower end part of the bath apron 9 is pushed toward the bathtub 1 as indicated by an arrow E shown in FIG. Thereby, the bath apron 9 can be attached to the side surface of the bathtub 1.

  The bath apron 9 is fitted between the flange portion 1 a of the bathtub 1 and the floor surface material 21. At this time, the bath apron 9 presses the groove portion 21 b of the outer edge portion 21 a on the bathtub 1 side of the floor surface material 21. Accordingly, the floor surface material 21 can be prevented from being lifted simultaneously with the installation of the existing bath apron 9, and the floor surface material 21 can be firmly fixed.

FIG. 11 is a schematic cross-sectional view for explaining a specific example of the attachment structure of the bath apron.
In the specific example shown in FIG. 11A, the bottom portion of the groove portion 21 b provided on the outer edge portion 21 a of the floor surface material 21 is pressed directly by the lower end 9 a of the bath apron 9.
In the specific example shown in FIG. 11B, a clip CP having a spring property is provided between the bath apron 9 and the floor surface material 21, which is adopted in this embodiment. The clip CP is a spring member that is normally used for backlash of the bath apron 9 in the vertical direction, and corresponds to a pressing member in the present invention. In this example, the pressing force of the bath apron 9 as the wall surface material in the present invention is transmitted to the bottom portion of the groove portion 21b provided in the outer edge portion 21a of the floor surface material 21 through the clip CP which is a pressing member.

  That is, in this embodiment, the bathtub 1 side of the floor material 21 is indirectly pressed by the bath apron 9, and the other three sides are directly pressed by the walls 3 such as the first to third wall panels 31 to 33. Will be. Therefore, the concave shape which generate | occur | produces qualitatively in the flooring material 21 by pressing down the outer edge part 21a corresponding to 4 sides of the flooring material 21 only with the existing member, without using the special member prepared for it. Therefore, it is possible to easily and reliably follow the floor base material 22 by correcting the overall deformation of the material.

Next, the fixing of the floor material 21 by the drain trap will be described.
FIG. 12 is a schematic cross-sectional view illustrating a fixed state of a drain trap that constitutes a pipe connection member in the present invention.

  As shown in FIG. 12, the drain trap 400 is fixed to the first frame 232 a of the support frame 232 by bolts or the like, for example, and the drain recess 230 that forms the trap body 410 and the drain port 26 of the floor material 21. A mounting flange (pipe connecting member) 420 provided with a male screw for mounting that sandwiches the water and a sealing cylinder 430 inserted into the drain recess 230 are provided. Further, the trap body 410 is provided with an opening 411 provided with a female thread for screwing the mounting flange 420, an inflow pipe connecting part 440 through which water drained from the bathtub 1 flows, and drainage communicating with an outdoor sewage pipe. A pipe connection portion 450 is provided.

  Then, the bottom surface portion 333 of the drainage recess 230 is sandwiched between the mounting flange 420 and the trap body 410 via packing or the like, and the mounting flange 420 is screwed into a female screw provided in the trap body 410 and tightened. Thus, the drain recess 230 of the floor surface material 21 can be connected to the drain trap 400 in a watertight manner.

  In the present embodiment, the floor base material 22 is also fixed to the support frame 232 with bolts or the like, and the upper surface thereof is used as a reference for the horizontal surface of the washing floor 2 as described above. An attachment reference surface 213 to the floor base material 22 is formed in the vicinity of the drain recess 230 on the lower surface (back surface) of the floor material 21. Accordingly, by performing the operation of watertightly connecting the drain recess 230 of the floor covering 21 to the drain trap 400, not only can the portion of the drain outlet 26 of the floor covering 21 be securely fixed, but the reference mounting surface 213 can be fixed to the floor. By being pressed against the upper surface of the base material 22, it is possible to simultaneously position the drain recess 230 as a starting point of the drain gradient of the floor material 21.

  In this embodiment, the drain recess 230 is formed integrally with the floor material 21, but the floor is formed by a member separate from the floor material 21 and integrated in a separate process. It is also possible to apply the present invention using a face material as the floor material 21. In that case, a new problem that may be caused by implementing the present invention can be easily solved. For example, by forming the drain recess 230 with another material, it is possible to easily increase the strength of the connection portion with the drain trap 400 that is a pipe connection member.

  In this embodiment, the pipe connection member has a trap function in addition to the pipe connection function. However, the present invention can also be applied to a structure having only the pipe connection function.

Next, the assembly procedure of the bathroom unit provided with the bathroom structure according to the present embodiment will be described.
13 to 16 are schematic perspective views for explaining the assembly procedure of the bathroom unit.
First, as shown in FIG. 13A, the support legs 231 and the support frame 232 of the floor holding member 23 are assembled at the installation location of the bathroom unit. Then, the floor base material 22 is placed and fixed on the support frame 232. Then, the level of the upper surface is checked, and if necessary, the leveling operation is performed by adjusting the height of the support leg 231 from the work port 221h. Next, the wall surface fixing member 51 is attached to the floor base material 22 or the support frame 232. The wall surface fixing member 51 is attached to a location corresponding to a position where the wall surface connection member 50 is erected in a later step.

  Next, as shown in FIG. 13B, the floor material 21 is placed on the floor base material 22. As described above, the floor surface material 21 of the present embodiment is configured as a floor surface member of an assembly in which the cushion material 201 and the skin material 202 are previously attached to the surface thereof. When such a flooring material 21 is used, only the operation of placing the flooring material 21 on the floor base material 22 is required. Since the floor material 21 is formed of foamed plastic, the weight of the product is light, and it is easy to carry out construction work such as carrying into the installation place or installing on the support frame 232.

  Note that this placing work can be performed before the work for attaching the wall surface fixing member. In this case, as described above, if a wall surface fixing member having a shape that can press the floor surface material 21 instead of the wall surface fixing member 51 and a single floor surface material 21 are used, the floor surface material 21 is used. Can be temporarily fixed to the floor base material 22. By doing so, it becomes possible to prevent the placement position of the floor covering 21 from being changed in subsequent operations.

  Subsequently, the drain trap 400 attached to the drain pipe 5 and the drain port 26 of the floor surface material 21 are connected by an attachment flange (pipe connecting member) 420. By this operation, the floor surface material 21 is fixed and the mounting reference surface 213 provided in the vicinity of the drain outlet 26 on the back surface of the floor surface material 21 is pressed against the upper surface of the floor base material 22 as described above. Positioning of the starting point is also performed.

  In this state, the floor material 21 is only fixed by the drain trap 400 at the position of the drain port. The floor material 21 may be deformed (warp or the like) during molding. Therefore, in a state where the floor surface material 21 is placed on the floor base material 22 and the drain trap 400 is attached, there is a possibility that the outer edge portion 21a of the floor surface material 21 is lifted.

  Next, as shown in FIG. 14, the bathtub 1 is attached on the support leg 6. A small panel 37 is attached between the bathtub 1 and the washing floor 2. Moreover, the bath apron 9 is attached to the side surface of the bathtub 1 as needed. When the bath apron 9 is attached, the outer edge portion 21 a on the bathtub 1 side of the floor surface material 21 is pressed by the bath apron 9 or the clip CP that fixes the bath apron 9.

  Next, as shown in FIG. 15, the wall surface connecting member 50 is attached to the outer peripheral portion 2 a of the washing floor 2. The wall surface connecting member 50 is fixed to a wall surface fixing member 51 attached in advance by fastening means such as bolts and screws. As a result, a plurality of wall surface connection members 50 are erected on the outer peripheral portion 2 a of the washing floor 2. When the wall surface connecting member 50 is fixed, the outer edge portion 21a of the floor surface material 21 may be pressed downward by the lower end of the wall surface connecting member 50.

  Next, as shown in FIG. 16, the wall 3 is attached. Of the wall 3, the first to fifth wall panels 31 to 35 are fixed by being fitted to the wall surface connection member 50. The sixth wall panel 36 on the opposite side of the bathtub 1 from the washing floor 2 is fixed between one end of the fourth wall panel 34 and one end of the fifth wall panel 35.

  Among these, the floor material 21 can be pressed from the top by fixing the 1st-3rd wall panels 31-33. Therefore, the outer edge 21a of the floor material 21 is pressed by fixing the existing first to third wall panels 31 to 33, and the floor material 21 is corrected to the floor base material in a state where the floating of the floor material 21 is corrected. 22 can be tightly fixed.

After this, equipment such as a bathtub / washing faucet will be installed, and the caulking process will be applied to the necessary places to complete the bathroom unit.
In addition, in the manufacturing method of the said bathroom unit, although the wall surface fixing member 51 is attached before attaching the flooring material 21 (refer FIG. 13 (a) and (b)), after attaching the flooring material 21 The wall surface fixing member 51 may be attached, and the outer edge portion 21a of the floor material 21 may be pressed downward during the attachment.

  In this case, as described above, if a wall surface fixing member having a shape that can press the floor surface material 21 instead of the wall surface fixing member 51 and a single floor surface material 21 are used, the floor surface material 21 is used. Can be temporarily fixed to the floor base material 22. By doing so, it becomes possible to prevent the placement position of the floor surface material 21 from being changed by various subsequent operations.

According to this embodiment, even if the outer edge portion 21a is lifted due to the molding warp of the floor surface material 21 formed of foamed plastic, it can be easily eliminated simply by mounting the wall 3.
As a result, the user can comfortably use the bathroom without feeling the rattling of the washing floor 2.

  When the bathroom structure according to the present invention as described above is applied to a bathroom structure using foamed plastic as a floor surface material, no special member or construction is required, and the floor surface material 22 can be easily and reliably applied. Provided is a bathroom structure that can be closely adhered to.
