<Example 1>
A first embodiment of the present invention will be described below with reference to FIGS.

<Overall configuration of bathroom floor 20>
The bathroom floor 20 of this embodiment is provided in the bathroom 10 of an apartment or a detached house. The bathroom 10 is composed of a washing place 11 and a bathtub 66 in terms of function. The bathroom floor 20 functions as a waterproof floor for the washing place 11. As shown in FIG. 1, a bathroom floor 20 includes a metal washroom frame 21 (a frame which is a constituent element of the present invention), five first support legs 28 attached to the washroom frame 21, and a synthetic resin. The wash basin 30 made of the product and three second support legs 40 attached to the wash basin pan 30 are configured. Further, a drain trap 50 and a bathtub frame 60 are assembled to the bathroom floor 20. In addition, about the front-back direction in the following description, the washing place 11 side is made into the front side, and the bathtub 66 side is made into the back side for convenience.

<Washing frame 21>
As shown in FIGS. 1 and 2, the washing frame 21 has a rectangular shape with the long side directed in the left-right direction as a whole, and includes a long-side beam 22 (a beam along the wall that is a constituent of the present invention) and a long-side beam. A pair of symmetrical short side beams 23 (beams along the wall, which is a constituent element of the present invention) that extend perpendicularly from the left and right ends of 22 to the rear, and both left and right short side beams 23 in parallel with the long side beam 22. And a boundary beam 24 connecting the rear ends of the two. As shown in FIG. 2, the long-side beam 22 and the short-side beam 23 are arranged along the three inner walls 12 constituting the washing place 11 in the inner wall 12 of the bathroom 10. The boundary beam 24 is disposed along the boundary between the washing place 11 and the bathtub 66 (tub area 17).

  The washing frame 21 includes a single inner beam 25 that extends between the left and right short side beams 23 in parallel with the long side beam 22 and the boundary beam 24. The inner beam 25 is longer than the center of the frame 21 for the washing place in a position slightly displaced toward the boundary beam 24 from the long side beam 22, that is, in the front-rear direction (direction parallel to the direction in which the washing place 11 and the bathtub 66 are arranged). It is arranged at a position close to the side beam 22 side. As shown in FIGS. 1 and 4, a pair of connecting legs 27 are fixed to the lower surface of the boundary beam 24 so as to protrude downward from each other.

<First support leg 28>
Each of the five first support legs 28 has a height adjustment (length adjustment) mechanism (not shown). As shown in FIGS. 2 and 4, three of the five first support legs 28 are provided at a substantially central position in the length direction of the inner beam 25 and positions near both ends of the inner beam 25. . The three first support legs 28 protrude downward from the inner beam 25 in the vertical direction. Two of the five first support legs 28 are provided on the connecting leg 27. The two first support legs 28 protrude downward from the lower end surface of the connecting leg 27 in the vertical direction. As shown in FIG. 2, the center first support leg 28 among the three first support legs 28 provided on the inner beam 25 is located between the first support legs 28 of the boundary beam 24 in the left-right direction, The two first support legs 28 on both sides are located closer to the end than the first support legs 28 of the boundary beam 24. These first support legs 28 can individually adjust the positions of their lower ends in the vertical direction. The lower end of the first support leg 28 is placed on and adhered to the upper surface of the floor slab 15 (washing area 16) of the bathroom 10.

<Washing pan 30>
As shown in FIGS. 3 and 4, the washing area pan 30 has a single plate shape as a whole, and has a long rectangle in the left-right direction so as to cover the entire washing area 16 in the floor slab 15. The washing area pan 30 has a shape and a size that substantially match with the washing area frame 21. The surface (upper surface) of the washing place pan 30 is a washing place floor and has a waterproof function. The peripheral edge 31 of the washing pan 30 is fixed in a state where it is placed on the upper surface of the long-side beam 22, the upper surface of the short-side beam 23, and the upper surface of the boundary beam 24 over the entire circumference. .

  As shown in FIGS. 1, 4, and 11, the upper surface of the wash basin 30 is inclined so as to have a downward slope toward the rear (tub 66 side) in the front-rear direction, and from the left and right ends toward the center in the left-right direction. It is inclined so as to have a downward slope. As shown in FIGS. 1, 3, and 8, an accommodation recess 32 having a shallow upper surface is formed at the lowest position of the wash basin 30 (the center position in the left-right direction at the rear edge of the wash basin 30). ing. As shown in FIG. 13, the planar shape of the accommodation recess 32 is a square as a whole. On the bottom surface of the housing recess 32, a circular washing-room drain port 33 having a penetrating shape communicating with the lower surface of the washing-room pan 30 is formed.

  As shown in FIGS. 1, 3 and 4, the eye plate 35 is detachably accommodated in the accommodation recess 32. The planar shape of the eye plate 35 is a square that substantially matches the receiving recess 32 as a whole, and the outer dimension of the eye plate 35 is set slightly smaller than the opening size of the receiving recess 32. As shown in FIG. 14, the upper surface of the eye plate 35 is inclined so as to have a downward slope toward the rear (tub 66 side) in the front-rear direction, as in the washing place pan 30, and from the left and right ends in the left-right direction. It is inclined so as to have a downward slope toward the center.

  Further, as shown in FIG. 15, four leg portions 36 project from the lower surface (back surface) of the eye plate 35. The leg portion 36 has an L-shaped planar shape and is disposed along the four corner edges of the eye plate 35. A disc-shaped rubber 55 is attached to the lower surface of each leg portion 36. When the eye plate 35 is correctly accommodated in the accommodating recess 32, the lower surface of the eye plate 35 is lifted from the bottom surface of the accommodating recess 32 by the legs 36. Accordingly, the hot water on the upper surface of the wash basin pan 30 has a gap between the inner peripheral surface of the accommodation recess 32 and the outer peripheral edge of the eye plate 35, between the legs 36, and between the lower surface of the eye plate 35 and the bottom surface of the accommodation recess 32. Are sequentially discharged and discharged from the washing ground drain 33.

  As shown in FIGS. 13 to 15, a drainage recess 34 is formed on the rear surface of the four inner peripheral surfaces of the accommodation recess 32, with the region except for the left and right ends being recessed shallowly rearward. Since the gap between the drain recess 34 and the outer peripheral edge of the eye plate 35 is larger than the inner peripheral surface of the housing recess 32, most of the hot water on the upper surface of the washing pan 30 is drained from the drain recess 34. Further, the drain recess 34 can be used as a handle when removing the eye plate 35. On the other hand, one of the four outer peripheral edges of the eye plate 35 is formed with an orientation protrusion 37 that protrudes from a position shifted in one direction from the center in the length direction. In a state in which the eye plate 35 is fitted in the receiving recess 32 in the correct orientation in the horizontal direction, the orientation determination protrusion 37 is positioned so as to approach or abut against one end of the drainage recess 34.

  On the other hand, even if the eye plate 35 is to be fitted into the receiving recess 32 in an improper orientation in the horizontal direction, the orientation determination projection 37 interferes with the opening edge of the receiving recess 32. It floats and the eye plate 35 cannot be accommodated in the accommodating recess 32. In this way, the eyepiece 35 can be accommodated in the correct orientation with respect to the accommodating portion by the drain recess 34 and the orientation protrusion 37.

  Further, the drain recess 34 is larger in the left-right direction than in the front-rear direction. At the left and right end portions of the drain recess 34, the rear surface of the drain recess 34 and the left and right sides are obtuse. Thus, since the drain recess 34 does not have narrow corners, the workability when cleaning the inner surface of the drain recess 34 is good. In addition, the orientation protrusion 37 does not protrude from the back surface of the eye plate 35 but protrudes outward from the outer periphery of the eye plate 35 in the planar direction. Therefore, the shape of the back surface of the eye plate 35 is simplified and easy to clean. Furthermore, since the orientation is determined by the outer periphery of the eye plate 35 and the drain recess 34, there is no need to provide an orientation projection in the receiving recess 32, and there are no narrow corners as in the drain recess 34. Therefore, workability at the time of cleaning the inner surface of the housing recess 32 is good.

  As shown in FIGS. 4, 11, and 12, the lower surface (back surface) of the washing place pan 30 has a plurality of protrusions that protrude downward substantially at right angles to the washing place pan 30 as means for increasing rigidity against a load acting on the upper surface of the washing place pan 30. The rib 38 is formed over the entire area of the washing area pan 30. The ribs 38 are arranged in a lattice shape along the front-rear direction and the left-right direction. A drainage pipe 54 connected to the drainage trap 50 is provided in the gap between the washing area pan 30 and the floor slab 15. However, as shown in FIG. In the region where the height of the pan 30 is relatively high, the rib 38 interferes with the drainage pipe 54 even if the rib 38 has a protruding dimension below the required dimension and the strength of the washing pan 30 is sufficiently increased. There is nothing. In addition, since the height of the drainage pipe 54 is higher in the central portion in the left-right direction, the downward projecting dimension of the rib 38 is set smaller in the left-right direction central portion than in the left-right end portions. However, the rigidity of the washing place pan 30 at the center in the left-right direction is sufficiently secured.

  Further, in the region where the piping position of the drain pipe 54 is relatively high and the height of the washing place pan 30 is relatively low, as shown in FIG. 11, the downward projecting dimension of the rib 38 extends over the entire region in the left-right direction. The dimensions are generally the same. However, since the height of the drainage pipe 54 is relatively high, a notch 39 for avoiding interference with the drainage pipe 54 is formed at the center in the left-right direction of the rib 38, that is, at a position corresponding to the drainage pipe 54. Has been. Moreover, the drain trap 50 is arrange | positioned in the clearance gap between the washing-room pan 30 and the floor slab 15, and is arrange | positioned so as to correspond to the lowest area | region in the front-back direction and the left-right direction among the washing-room pan 30. Therefore, a notch (not shown) for avoiding interference with the drain trap 50 is formed in a region corresponding to the drain trap 50 in the rib 38.

<Second support leg 40>
As shown in FIGS. 1 and 8, the washing area pan 30 is provided with three second support legs 40 having a height adjustment (length adjustment) mechanism (not shown). A central region surrounded by the peripheral edge portion 31 of the wash basin 30 is supported by the three second support legs 40. The three second support legs 40 protrude downward from the lower surface of the washing area pan 30 in the vertical direction. The second support leg 40 can individually adjust the position of its lower end in the vertical direction. And the lower end of the 2nd support leg 40 is mounted in the upper surface of the floor slab 15 (washing area 16) of the bathroom 10, and is adhere | attached.

  As shown in FIG. 3, the three second support legs 40 are arranged in a line in the left-right direction. Of the three second support legs 40, the two second support legs 40 at both ends are arranged so as to correspond to the two first support legs 28 arranged at both ends in the left-right direction. Further, in the left-right direction, the first support leg 28 on the right side of the boundary beam 24 is positioned between the second support leg 40 on the right side and the second support leg 40 near the center, and the second support leg 40 on the left side is located. The first support leg 28 on the left side of the boundary beam 24 is located between the first support leg 40 and the second support leg 40 near the center. In other words, the second support leg 40 and the first support leg 28 of the boundary beam 24 located closer to the bathtub 66 than the second support leg 40 are in a positional relationship shifted from each other in the left-right direction. The three second support legs 40 are arranged at a position between the inner beam 25 and the boundary beam 24 in the front-rear direction and closer to the boundary beam 24 than the inner beam 25. That is, the second support leg 40 is disposed at a position closer to the bathtub 66 side than the center of the frame 21 for the washing place in the front-rear direction.

<Drain trap 50>
As shown in FIGS. 1, 2, and 4, the drain trap 50 includes a washing-room inlet 51 that opens to the upper surface, a bathtub inlet 52 that opens to the upper surface, and an outlet 53 that opens to the front surface. The drain trap 50 is disposed in a gap between the floor slab 15 and the washing place pan 30 and in a gap between the floor slab 15 and the bathtub waterproof pan 64. The washing ground inlet 51 is connected to the washing ground drain 33 of the washing ground pan 30, and the bathtub inlet 52 is connected to the bathtub drain 65 of the bathtub waterproof pan 64. The upstream end of the drain pipe 54 is connected to the outlet 53.

<Bath frame 60>
As shown in FIGS. 1 and 2, the bathtub frame 60 includes a pair of left and right side beams 61 that are elongated in the front-rear direction, and a pair of front and rear connection beams 62 that are elongated in the left-right direction and connect the left and right side beams 61. Has been. The front end portion of each side beam 61 is coupled to the connecting leg 27. The side beam 61 and the connecting beam 62 are installed at a position lower than the washing place frame 21. One third support leg 63 having a height adjustment (length adjustment) mechanism (not shown) is provided near the rear end of each side beam 61. The third support leg 63 protrudes downward from the lower surface of the side beam 61 in the vertical direction. The third support leg 63 can be individually adjusted in the vertical direction at the lower end position. And the lower end of the 3rd support leg 63 is mounted in the upper surface of the bathtub area | region 17 of the floor slab 15, and is adhere | attached.

<Waterproof pan 64 for bathtub, bathtub 66, apron 67>
As shown in FIG. 4, a bathtub waterproof pan 64 having a box shape in which the upper surface and the front surface (side surface on the washing place 11 side) are opened is fixed to the bathtub frame 60 in a mounted state. A bathtub drain port 65 is formed through the bottom surface of the bathtub waterproof pan 64. A bathtub 66 for storing hot water is accommodated in the bathtub waterproof pan 64. An apron 67 for covering the outer surface of the bathtub 66 on the washing place 11 side is attached to the bathtub waterproof pan 64. The apron 67 includes an apron main body 69 assembled to the bathtub waterproofing pan 64 and a decorative board 68 assembled to the apron main body 69. The apron main body 69 is formed with an inspection port 69A. The surface of the decorative board 68 faces the washing place 11.

<Construction procedures for bathroom floor 20 and bathtub 66, etc.>
The installation of the bathroom floor 20 in the bathroom 10 is performed according to the following procedure. First, the washing frame 21 is carried into the bathroom 10, and the long side beams 22 and the short side beams 23 are brought into contact with the inner wall 12 facing the washing place 11 of the inner walls 12 of the bathroom 10, and the first support legs 28 are placed on the floor. Place on slab 15. Then, by adjusting the lengths of the five first support legs 28, the level is adjusted so that the frames 22, 23, 24, 25 are horizontal. After the level of the washing frame 21 is adjusted, all the first support legs 28 are bonded and fixed to the floor slab 15.

  Of the five first support legs 28, the three first support legs 28 along the long side of the washing frame 21 are not the long side beams 22 but the longer side beams 22 than the long side beams 22 (that is, , In a direction away from the inner wall 12). Therefore, as shown in FIG. 4, even if the overhanging portion 13 such as a reverse beam or an existing pipe protrudes along the inner wall 12 on the side opposite to the bathtub 66 of the inner wall 12 of the washing place 11, these three The first support leg 28 does not interfere with the overhanging portion 13.

  After the washing frame 21 is installed, the bracket 42 is attached to the center of the boundary beam 24 in the length direction. Next, the drain trap 50 is assembled to the bracket 42. In the state in which the drain trap 50 is assembled, the washing ground inlet 51 and the bathtub inlet 52 are arranged so as to sandwich the boundary beam 24 therebetween. After the drain trap 50 is assembled, the drain pipe 54 is routed in the washing place 11, and the upstream end of the drain pipe 54 is connected to the outlet 53 of the drain trap 50.

  The assembly work of the drain trap 50, the routing work of the drain pipe 54, and the connection work of the drain trap 50 and the drain pipe 54 are all performed before the washing place pan 30 is attached to the washing place frame 21. In the state before the washing place pan 30 is attached, what exists in the washing place 11 is the long side beam 22, the short side beam 23, the boundary beam 24, and the long side beam 22 arranged along the outer peripheral edge of the washing place 11. Only the inner beam 25 arranged at a close position. That is, most of the washing place 11 is an open area without any other members that obstruct the assembly work of the drain trap 50, the routing work of the drain pipe 54, and the connection work.

  After the assembly of the drain trap 50 and the connection of the drain pipe 54 are completed, the washing place pan 30 is placed on the washing place frame 21 and fixed. At this time, the peripheral edge 31 of the washing pan 30 is brought into contact with the upper surface of the long side beam 22, the upper surface of the short side beam 23, and the upper surface of the boundary beam 24. Thereby, the peripheral part 31 of the washing place bread | pan 30 is supported by the frame 21 for washing places over the perimeter. Then, the placed peripheral edge 31 is fixed to the long side beam 22 and the short side beam 23.

  Here, the fixing structure (support structure) of the long-side beam 22 and the washing place pan 30 will be described. As shown in FIG. 5, the peripheral portion 31 of the washing pan 30 is formed with a bent portion 43 that is bent so that the cross-section is substantially U-shaped and a groove 44 is opened on the upper surface. The bent portion 43 is directly placed on the upper surface of the long side beam 22. The bent portion 43 and the long side beam 22 are fixed by screws 45 that pass through the bottom surface of the groove 44 in the vertical direction and are screwed into the upper surface of the long side beam 22. The groove 44 is filled with a silicon sealing material 46 for sealing the through portion of the screw 45. A support bar 47 is fitted into the opening of the groove 44, and the lower end edge of the inner wall panel 14 is fixed to the upper surface of the support bar 47. The gap between the support bar 47 and the lower edge of the inner wall panel 14 is filled with a silicon sealant 48 to seal the gap. The fixing structure of the short side beam 23 and the boundary beam 24 and the washing place pan 30 is the same as that of the long side beam 22.

  Further, the washing place pan 30 placed on the washing place frame 21 covers the drain trap 50 and the drain pipe 54 from above. Since the reinforcing ribs 38 are formed in a lattice shape over the entire area of the bottom surface of the washing pan 30, there is a concern that the ribs 38 may interfere with the drain trap 50 and the drain pipe 54. However, in this embodiment, since the notch 39 is formed in the rib 38, there is no possibility that the rib 38 interferes with the drain trap 50 and the drain pipe 54. Further, since the cutout portion 39 is formed only in the minimum necessary portion for avoiding interference, even if the cutout portion 39 is formed, the strength increasing function as the entire rib 38 is hardly impaired, The rigidity of the washing area pan 30 is sufficiently maintained.

  After the washing area pan 30 is fixed to the washing area frame 21, the washing area inlet 51 and the washing area drain 33 are connected and fixed in a liquid-tight manner. Thereafter, the lengths of the three second support legs 40 are adjusted so that the lower ends of the second support legs 40 reach the upper surface of the floor slab 15 (washing area 16). When all the second support legs 40 are placed in contact with the floor slab 15, the second support legs 40 are fixed to the floor slab 15 with an adhesive. The central portion of the washing area pan 30 is supported by the second support legs 40. Since the peripheral edge portion 31 of the washing place pan 30 is supported by the washing place frame 21, the washing place pan 30 is stably supported over the entire region.

  Since the work of adjusting the length of the second support leg 40 and bonding is performed before installing the bathtub waterproofing pan 64, the operator puts his hand in the gap between the washing pan 30 and the floor slab 15 from the bathtub region 17 side. You can work with it. Here, the three second support legs 40 are arranged at a position closer to the bathtub 66 (tub area 17) side than the center of the washing area pan 30 in the front-rear direction (the direction in which the washing area 11 and the bathtub 66 are arranged). Therefore, it is easy to reach the second support leg 40. In addition, the second support leg 40 is disposed at a position closer to the bathtub region 17 than the drain pipe 54 in the front-rear direction, and is disposed at a position shifted from the drain trap 50 in the left-right direction. Therefore, when the hand is extended from the bathtub region 17 side toward the second support leg 40, the drain pipe 54 and the drain trap 50 do not get in the way. As described above, the workability when installing the second support leg 40 on the floor slab 15 is excellent.

  After installation of the washing area pan 30 is completed, installation work on the bathtub 66 side is performed. First, the bathtub frame 60 is carried into the bathtub region 17, and the front end portion of the side beam 61 is temporarily assembled to the connecting leg 27 of the washing frame 21 via bolts (not shown) whose axis is directed in the left-right direction. Thereby, the frame 60 for bathtubs is positioned in a horizontal direction. Then, the length of the third support leg 63 is adjusted to adjust the level so that the side beam 61 and the connecting beam 62 are horizontal. After adjusting the level of the bathtub frame 60, all the third support legs 63 are bonded and fixed to the floor slab 15, and nuts (not shown) are fastened to the bolts and the wash frame 21 (the connecting legs 27). The bathtub frame 60 (side beam 61) is fixed. Thereafter, the bathtub waterproof pan 64 is placed and fixed on the bathtub frame 60, and the bathtub 66 is accommodated and fixed in the bathtub waterproof pan 64. Then, the bathtub drain 65 and the bathtub inlet 52 are connected. Finally, the apron 68 is assembled to the front surface of the bathtub waterproof pan 64 (the outer surface on the washing place 11 side). Thus, the installation of the bathtub 66 and the like is completed.

<Operation and Effect of Example>
In this embodiment, the bathroom 21 can easily support the washing area pan 30 over the entire area while performing the plumbing work of the drain trap 50 and the drain pipe 54 with the frame 21 for the washing area installed on the floor slab 15. The problem is to provide the floor 20. As a means for solving the problem, the bathroom floor 20 of the present embodiment extends downward from the washing place frame 30, the washing place frame 21 that supports the washing place bread 30 in a state where the peripheral edge 31 of the washing place bread 30 is placed, and the washing place frame 21.
