Description

  The present invention relates to a bathroom wash floor structure.

  In the bathroom washroom floor structure, the floor material (base material) made of thermoplastic foam resin is placed on a steel deck plate or a sandwich panel reinforced by sandwiching a resin plate between two steel plates. The structure to be known is known. The deck plate and sandwich panel are fixed on a steel frame body. The frame body has an outer frame, support legs, and the like, and is installed on the building frame via the support legs.

  In such a bathroom wash floor structure, a work port (inspection port) is provided in the deck plate or sandwich panel, and the support legs are adjusted (level adjustment of the floor surface) through the work port. At this time, the lower frame body is covered with a deck plate or a sandwich panel at a portion other than the work opening. For this reason, it is difficult to visually recognize a wide range below (back side) the frame body.

  On the other hand, if the floor material made of thermoplastic foam resin is placed directly on the grid frame body without installing a deck plate or sandwich panel, a person who is placed on the bathroom washroom floor Due to the load, the floor material is greatly sunk in the gaps between the lattices, and the walking comfort is deteriorated, and the drainage gradient necessary for the bathroom washing floor cannot be properly maintained.

  Therefore, for example, in Patent Document 1, a structure in which the frame interval of the frame body is narrowed to 7 cm or less and a floor surface material made of thermoplastic foam resin is supported by the frame body without providing a deck plate or a sandwich panel is studied. Yes.

  However, in the structure of Patent Document 1, the lower visibility of the frame body can be ensured, but since the lattice interval is narrow, it is difficult for the operator to enter the body and the arm. Therefore, even if it can be visually recognized, it is difficult to work through the lattice, and there is still room for examination in workability.

FIG. 2 is a perspective view schematically showing the washing floor structure of the bathroom unit according to the embodiment.
As shown in FIG. 2, the washing floor 10 includes a floor body 15 and a frame body 30. The floor main body 15 includes a floor surface material 11, a cushion layer 12, and a surface material 13. The floor material 11, the cushion layer 12, and the surface material 13 are all formed of resin.

  The floor surface material 11 of the floor main body 15 is placed on the frame body 30 and supported by the frame body 30. The floor surface material 11 is formed in a shallow vessel shape (bread shape) whose peripheral portion is bent upward.

  The floor material 11 is formed of a thermoplastic foam resin. Examples of the thermoplastic foamed resin include foamed polypropylene, foamed polystyrene, foamed polyethylene, and foamed polyurethane. In this embodiment, foamed polypropylene is used as an example.

  An opening 21 for a drain outlet is formed in the floor surface material 11. The portion provided with the opening 21 is formed in a concave shape. In addition, a drainage gradient inclined downward toward the opening 21 is formed on the surface of the floor covering 11.

  The surface material 13 is provided on the floor surface material 11 via the cushion layer 12. The cushion layer 12 is provided between the floor material 11 and the surface material 13. The elasticity of the cushion layer 12 is higher than the elasticity of the floor material 11 and the surface material 13. The cushion layer 12 has an opening 22 for a drain outlet.

  The cushion layer 12 gives the user a soft feeling on the floor. As the material of the cushion layer 12, for example, a soft material such as foamed polyurethane is used. By changing the hardness (softness) of the cushion layer 12, the specification of the hardness (softness) of the floor surface can be changed. The cushion layer 12 is provided as needed and can be omitted.

  The surface material 13 covers the upper surfaces of the floor surface material 11 and the cushion layer 12, and forms the surface 15a of the floor body 15 (washing floor 10). The surface material 13 imparts appearance designability and waterproofness to the surface 15 a of the floor body 15.

  As the material of the surface material 13, a soft resin sheet material having waterproofness and flexibility is used. In order to improve the designability and drainage of the surface 15a of the floor body 15, the surface of the surface material 13 can be subjected to uneven processing or a pattern.

  An opening 23 for a drain outlet is formed in the surface material 13. Further, a drainage gradient inclined downward toward the opening 23 is formed on the surface of the surface material 13. Due to the drainage gradient of the floor material 11 and the drainage gradient of the surface material 13, a drainage gradient inclined downward toward the drainage port is formed on the surface 15 a of the floor body 15.

  The frame body 30 supports the floor body 15 from below. The frame body 30 includes a metal outer frame 31, a metal lattice portion 32, and metal support legs 33. The outer frame 31 and the lattice part 32 are formed by combining steel materials, for example, and have sufficiently higher strength than the floor main body 15 formed from resin.

  The outer frame 31 has four frames 31a to 31d. The four frames 31a to 31d are combined in a square shape to form the outer shape (outline) of the outer frame 31. The frame 31a and the frame 31b extend in parallel, and the frame 31c and the frame 31d extend in parallel. The area of the quadrangular area formed by the four frames 31 a to 31 d is substantially the same as the area of the quadrangular area formed by the floor body 15.

  The length of the frames 31a and 31b is longer than the length of the frames 31c and 31d. The outer frame 31 has, for example, a rectangular shape when viewed from above. The frames 31a and 31b extend in the first horizontal direction HD1. The frames 31c and 31d extend in a second horizontal direction HD2 orthogonal to the first horizontal direction HD1. The first horizontal direction HD1 is, for example, the longitudinal direction of the rectangular outer frame 31, and the second horizontal direction HD2 is, for example, the short direction of the rectangular outer frame 31. In other words, the first horizontal direction HD1 is a direction orthogonal to the direction in which the washing place floor 10 and the bathtub 60 are arranged, and in other words, the second horizontal direction HD2 is a direction in which the washing place floor 10 and the bathtub 60 are arranged. Parallel direction.

  The lattice portion 32 partitions the inside of the outer frame 31 into a lattice shape. The lattice part 32 suppresses the bending of the floor main body 15 by, for example, supporting a portion inside the outer frame 31 of the floor main body 15. As described above, by providing the lattice portion 32, the floor body 15 can be more appropriately supported by the frame body 30.

  The lattice portion 32 includes, for example, a plurality of first extending portions 41 and a plurality of second extending portions 42. Each first extending portion 41 extends in the first horizontal direction HD1 and is arranged in the second horizontal direction HD2. Each second extending portion 42 extends in the second horizontal direction HD2 and is arranged in the first horizontal direction HD1. Thereby, the lattice part 32 partitions the inner side of the outer frame 31 so that a plurality of rectangular gaps are arranged in the first horizontal direction HD1 and the second horizontal direction HD2.

  Further, a part 41a of the plurality of first extending portions 41 is provided between the frame 31c and the frame 31d. Another part 41 b of the plurality of first extending portions 41 is provided between the second extending portions 42. As described above, the extending portion may extend entirely between the frames of the outer frame 31, or may extend only to a part between the frames of the outer frame 31.

  However, the configuration of the lattice portion 32 is not limited to the above. For example, the lattice portion 32 may have only a plurality of first extending portions 41 or may have only a plurality of second extending portions 42. The extending direction of the plurality of extending portions may be a direction different from the first horizontal direction HD1 and the second horizontal direction HD2. The configuration of the lattice portion 32 may be an arbitrary configuration that can partition the inside of the outer frame 31 in a lattice shape and appropriately support the floor body 15.

  The frame body 30 includes, for example, four support legs 33 provided corresponding to the four corners of the rectangular outer frame 31. Each support leg 33 is provided on the lower surface of the lattice portion 32. Each support leg 33 extends downward (installation surface side) from the lower surface of the lattice portion 32. Each support leg 33 may be provided on the lower surface of the outer frame 31.

  The frame body 30 is installed on the installation surface 100 via the support legs 33. A bolt portion is provided on the front end side (lower end side) of each support leg 33, and the height of each support leg 33 can be adjusted by rotating the bolt portion. By adjusting the height of each support leg 33, the installation height and levelness of the floor main body 15 supported on the frame body 30 are adjusted.

  In addition, the lattice portion 32 is provided with a plate in which an opening 34 for a drain port is formed. The frame body 30, the floor material 11, the cushion layer 12, and the surface material 13 are overlapped with the positions of the respective openings 21, 22, 23, and 34 being aligned. A drainage pit is provided inside each of the openings 21, 22, 23, 34. The drainage pit is made of resin and has non-water permeability. A drain outlet is provided inside the drain pit. This drain outlet is connected to the drain pipe 62. Thereby, the water that has flowed to the surface 15a of the floor main body 15 (washing floor 10) is drained to the drain pipe 62 through the drain pits.

FIG. 3 is a bottom view schematically illustrating the washing floor structure of the bathroom unit according to the embodiment.
FIG. 4 is a cross-sectional view schematically showing the washing place floor structure of the bathroom unit according to the embodiment.
FIG. 4 schematically shows a cross section taken along line A1-A2 of FIG.
As shown in FIGS. 3 and 4, the washing floor 10 further includes a sinking suppression body 50. The sinking suppression body 50 is provided below the surface 15 a of the floor body 15 and is provided on the frame body 30 without being directly fixed to the frame body 30. In the present invention, the subsidence suppression body 50 is “directly fixed” to the frame body 30. The subsidence suppression body 50 is screwed and fixed to the frame body 30, an adhesive, or the like. For example, it is adhered and fixed by. On the other hand, in the present invention, the subsidence suppression body 50 is “not directly fixed” to the frame body 30. The subsidence suppression body 50 is “indirectly fixed only to the frame body 30. Are included in the definition. For example, the floor body 15 to which the sinking suppression body 50 is fixed is also included in the definition in which the floor body 15 is fitted and fixed to the frame body 30.

  The sinking suppression body 50 has higher rigidity than the floor surface material 11. For the sinking suppression body 50, for example, a metal material such as aluminum, stainless steel, or iron, or a hard resin material is used. Thereby, the sinking suppression body 50 suppresses the sinking of the floor surface material 11.

  The sinking suppression body 50 is provided on the floor body 15. More specifically, the subsidence suppressing body 50 is provided in the lower part of the floor surface material 11. The sinking suppression body 50 is embedded in the lower part of the floor surface material 11, for example. Thereby, the sinking suppression body 50 is mounted on the frame body 30 together with the floor surface material 11.

  Thus, the sinking suppression body 50 is not directly fixed to the frame body 30 by screwing or bonding. The state that is not directly fixed is, for example, a state that can be easily attached to and detached from the frame body 30 without using a tool or the like. For example, it is in a state where it is simply placed on the frame body 30. The sinking suppression body 50 can be attached to and detached from the frame body 30.

  However, in the state where the bathroom unit 2 is assembled, the sinking suppression body 50 is, for example, a tightening flange (a connecting member between the drain pit and the drain pipe 62 provided at the drain port of the floor surface material 11 and the floor body 15. ) And the like may be indirectly fixed to the frame body 30. The sinking suppression body 50 is detachable without being fixed to the frame body 30 at least at the stage of construction of the frame body 30 and the floor surface material 11.

  The sinking suppression body 50 includes a plurality of first lateral support members 51a to 51g and a plurality of second lateral support members 52a and 52b. The first lateral support members 51a to 51g extend in the first horizontal direction HD1 and have a thickness in the height direction. The thickness in the height direction of the first lateral support members 51a to 51g is, for example, not less than 10 mm and not more than 150 mm. For example, the first horizontal support members 51a, 51c, 51e, 51f, and 51g extend in the first horizontal direction HD1 and are arranged in the second horizontal direction HD2. Similarly, the first horizontal support members 51b, 51d, 51e, 51f, and 51g extend, for example, in the first horizontal direction HD1 and are arranged in the second horizontal direction HD2. The first lateral support members 51a and 51b are arranged in the first horizontal direction HD1. The first horizontal support members 51c and 51d are arranged in the first horizontal direction HD1.

  The second horizontal support members 52a and 52b extend in the second horizontal direction HD2 and are arranged in the first horizontal direction HD1. The second lateral support members 52a and 52b have a thickness in the height direction. The thickness in the height direction of the second lateral support members 52a and 52b is, for example, not less than 10 mm and not more than 150 mm. The first lateral support members 51a to 51g are provided between the second lateral support members 52a and 52b.

  However, the number and arrangement of the first lateral support material and the second lateral support material are not limited to the above, and may be arbitrary. The extending direction of the plurality of lateral support members is not limited to the first horizontal direction HD1 and the second horizontal direction HD2, and may be any horizontal direction.

  The upper ends of the plurality of first lateral support members 51 a to 51 g are located above the lower end 11 a of the floor surface material 11. The lower ends of the plurality of first lateral support members 51 a to 51 f are substantially flush with the lower end 11 a of the floor surface material 11. Thereby, as shown in FIG. 4, when the floor material 11 is placed on the frame body 30, the first lateral support members 51 a to 51 f are also placed on the floor material 11.

  Here, “substantially flush” is, for example, a state in which the height difference between the lower end of the first lateral support member and the lower end 11a of the floor member 11 is ± 3 mm or less. Note that the lower end of the first horizontal support member may be positioned above the lower end 11a of the floor surface member 11 like the first horizontal support member 51g. On the contrary, the lower end of the first horizontal support member may be positioned below the lower end 11a of the floor member 11.

  Similarly, the upper ends of the second lateral support members 52 a and 52 b are positioned above the lower end 11 a of the floor surface material 11. The lower ends of the second lateral support members 52a and 52b are located above the lower end 11a of the floor surface material 11, for example. The lower ends of the second horizontal support members 52a and 52b may be substantially flush with the lower end 11a of the floor covering 11 or may be positioned below the lower end 11a.

  The first horizontal support members 51a to 51f have, for example, a square pipe shape (square tube shape) with a substantially rectangular cross section. On the other hand, the first lateral support member 51g has, for example, a round pipe shape (cylindrical shape) with a substantially circular cross section. In addition, the second lateral support members 52a and 52b have, for example, a round pipe shape with a substantially circular cross section. Square pipes have higher rigidity than round pipes, but are more expensive than round pipes. Therefore, when the surface 15a of the floor main body 15 has a drainage gradient, a square pipe-shaped lateral support material is provided near the drainage port (the lowest point of the drainage gradient) and the thin portion of the floor main body 15 is thin. A round pipe-shaped lateral support material is used for the thick part of the floor main body 15 near the outer periphery. For example, a square pipe is used for a lateral support member closest to the drain outlet among the plurality of lateral support members, and a round pipe is used for a lateral support member farthest from the drain outlet among the plurality of lateral support members. Thereby, the manufacturing cost of the washing place floor 10 can be suppressed while suppressing the sinking of the floor surface material 11 appropriately.

FIG. 5 is a plan view schematically showing the washing place floor structure of the bathroom unit according to the embodiment.
As shown in FIG. 5, the plurality of first lateral support members 51 a to 51 g and the second lateral support members 52 a and 52 b are at least partially overlapped with the outer frame 31 and the lattice portion 32 of the frame body 30 in a top view. It is placed in a position that does not become necessary.

  The plurality of first extending portions 41 of the lattice portion 32 extend in the same direction as the plurality of first lateral support members 51a to 51g. In a top view, the interval PT1 between the plurality of first extending portions 41 and the plurality of first lateral support members 51a to 51g is 10 cm or less. In other words, in the top view, the size of the gaps between the plurality of first extending portions 41 and the plurality of first horizontal support members 51a to 51g is 10 cm or less. Here, the size of the gap represents the maximum diameter of a circle that can be accommodated in the gap that is vacant between the plurality of first extending portions 41 and the plurality of first lateral support members 51a to 51g.

  The plurality of second extending portions 42 of the lattice portion 32 extend in the same direction as the plurality of second lateral support members 52a and 52b. In a top view, the interval PT2 between the plurality of second extending portions 42 and the plurality of second lateral support members 52a and 52b is 10 cm or less. More specifically, the intervals PT1 and PT2 are intervals between the extending portion and the lateral support material adjacent thereto.

  A plurality of first lateral support members 51d to 51f are disposed between a part of the plurality of first extending portions 41. Thereby, some space | interval PT3 of the some 1st extension part 41 can be 14 cm or more. Further, a part of the intervals PT4 of the plurality of second extending portions 42 is 14 cm or more.

  As shown in FIGS. 4 and 5, the washing floor 10 further includes a cushion portion 54. The cushion portion 54 is provided between the sinking suppression body 50 and the frame body 30. The cushion portion 54 has lower rigidity than the sinking suppression body 50 and the frame body 30. The cushion part 54 has elasticity, for example. For the cushion portion 54, for example, a thermoplastic foam resin similar to the floor surface material 11 is used. The cushion part 54 is a sheet of a thermoplastic foam resin having a thickness of about 1 mm to 5 mm, for example. However, the material of the cushion portion 54 is not limited to the above, and may be any material having rigidity (elasticity) lower than that of the sinking suppression body 50 and the frame body 30.

  As described above, according to the wash floor 10 (bathroom wash floor structure) according to the present embodiment, the floor 10 is provided below the surface 15a of the floor body 15 and is directly fixed to the frame body 30. The frame body 30 is provided with a subsidence suppression body 50 that is provided on the frame body 30 and has higher rigidity than the floor surface material 11 and suppresses the sinking of the floor surface material 11. Even when the floor surface material 11 made of thermoplastic resin is disposed on the floor, it is possible to suppress the floor surface material 11 from greatly sinking due to a load when a person is placed on the washing floor 10. Further, it is not necessary to provide a lattice or the like with a narrow interval on the frame body 30, ensuring visibility below the frame body 30, and facilitating adjustment of the support legs 33. Accordingly, it is possible to improve the workability while solving the problem that the floor material 11 sinks greatly and the walking comfort becomes worse and the problem that the drainage gradient necessary for the washing floor 10 cannot be properly maintained.

  Further, in the washing floor 10, the floor surface material 11 is greatly sunk by the plurality of first lateral support members 51a to 51g and the plurality of second lateral support members 52a and 52b having a thickness in the height direction. It can suppress more reliably. Furthermore, when the upper ends of the first lateral support members 51a to 51g and the second lateral support members 52a and 52b are positioned above the lower end 11a of the floor surface material 11, the first lateral support members 51a to 51g and the second lateral support members 51a to 51g. It is possible to suppress the occurrence of a large step at the bottom of the floor surface material 11 between the place where the horizontal support members 52a and 52b are placed and the place where the side support materials 52b are not placed. Can be maintained properly.

  Further, in the washing floor 10, the first horizontal support members 51a to 51g and the second horizontal support members 52a and 52b are at positions where at least a part thereof does not overlap with the outer frame 31 and the lattice portion 32 of the frame body 30 in a top view. By being arranged, it is possible to more reliably suppress the floor material 11 from sinking even when the number of the lateral support members is small.

  Further, in the washing floor 10, in the top view, the interval PT1 between the plurality of first extending portions 41 and the plurality of first lateral support members 51a to 51g is 10 cm or less, and the plurality of second extending portions 42 and A distance PT2 between the plurality of second lateral support members 52a and 52b is 10 cm or less. Thereby, the several 1st extension part 41, the 2nd extension part 42, the 1st horizontal support material 51a-51g, and the 2nd horizontal support material 52a, 52b suppress the sinking of the floor surface material 11 firmly. can do.

  The intervals PT1 and PT2 are more preferably 7 cm or less. By setting the distances PT1 and PT2 to be not more than 7 cm, for example, the distances PT1 and PT2 can be made smaller than the foot size of a person who can walk on two legs. Therefore, even if a person stands on the washing floor 10 and a load is applied, the load from the soles of the feet can be received by the frame body 30 and the sinking suppression body 50, and it can be prevented from being greatly bent. For this reason, the washing place floor 10 with a more stable feeling can be provided. Thus, the distances PT1 and PT2 are more preferably 7 cm or less in view of the size of the child's foot.

  In the washing floor 10, a part of the floor surface material 11 is provided between the first lateral support members 51a to 51g and the second lateral support members 52a and 52b. In other words, a part of the floor material 11 is filled between the inserted first lateral support members 51a to 51g and the second lateral support members 52a and 52b. In this case, the sinking of the floor surface material 11 and the spread in the width direction can be suppressed by a plurality of sandwiched lateral support members. Therefore, for example, even if the distances PT1 and PT2 are set in the range of 7 cm to 10 cm, the floor material 11 will sink greatly due to the load of a child with a relatively light weight of about 7 cm foot size. It can suppress more reliably.

  For example, as described above, some of the intervals PT3 of the plurality of first extending portions 41 and some of the intervals PT4 of the plurality of second extending portions 42 can be set to 14 cm or more. Thereby, it is easy to put the installer's arm or the like below the frame body 30, and the workability can be further improved.

  Further, the washing floor 10 further includes a cushion portion 54, so that when the load is applied to the sinking suppression body 50, abnormal noise is generated by contacting the metal frame body 30, or the frame body 30. It is possible to prevent the sinking suppression body 50 from being damaged.

FIG. 6 is a cross-sectional view schematically showing a modification of the wash floor structure of the bathroom unit according to the embodiment.
Note that components that are substantially the same in function and configuration as those in the above embodiment are given the same reference numerals, and detailed descriptions thereof are omitted.
As shown in FIG. 6, the lower end of the sinking suppression body 50 (first lateral support members 51 e and 51 f) is positioned above the lower end 11 a of the floor surface material 11 in the washing floor 10 a. In the washing floor 10a, a part of the floor surface material 11 extends below the sinking suppression body 50. In other words, the sinking suppression body 50 is embedded in the floor surface material 11 in the wash floor 10a. Thereby, in the washing floor 10a, a part of the floor surface material 11 extending below the sinking suppression body 50 functions as the cushion part 11b.

  Thus, a cushion part may use a part of flooring material 11 as a cushion part 11b, without providing as a separate member. Also in this case, it is possible to suppress the occurrence or damage of abnormal noise as in the case where another cushion portion 54 is provided.

FIG. 7 is a bottom view schematically illustrating a modified example of the wash floor structure of the bathroom unit according to the embodiment.
As shown in FIG. 7, the sinking suppression body 50 includes a plurality of first lateral support members 51 and a plurality of second lateral support members 52 in the washing floor 10 b. The plurality of first lateral support members 51 extend in the first horizontal direction HD1 and are arranged in the second horizontal direction HD2. The plurality of second lateral support members 52 extend in the second horizontal direction HD2 and are arranged in the first horizontal direction HD1. In the washing floor 10b, the plurality of first lateral support members 51 are connected to the plurality of second lateral support members 52. In the washroom floor 10b, the subsidence suppression body 50 is configured as one lattice-shaped member. As described above, the subsidence suppressing body 50 may be constituted by one member, or may be constituted by a plurality of independent members as described with reference to FIG.

  In the washing floor 10b, the distance PT11 between the plurality of first lateral support members 51 is 10 cm or less in a top view. In other words, in the top view, the size of the gap between each of the plurality of first lateral support members 51 is 10 cm or less.

  Thus, in the subsidence suppression body 50, you may make it the space | interval PT11 be 10 cm or less. Thereby, sinking of the floor surface material 11 can be more reliably suppressed while improving workability. Further, in this way, when the interval PT11 is 10 cm or less, the lattice portion 32 of the frame body 30 may be omitted. Thereby, workability | operativity can be improved more, suppressing the sinking of the floor surface material 11. FIG. The distance PT11 is more preferably 7 cm or less in view of the size of the child's foot.
