  The main body 61 has a hollow conical shape. Openings are formed at the upper and lower ends of the main body 61. On the inner surface of the main body portion 61, at a position about one third lower than the height of the main body portion 61 from the upper end of the main body portion 61, there is a thin portion 611 in which the thickness of the main body portion 61 is configured to be thin. ing. The thin portion 611 is formed so as to make a round around the axis of the main body 61, and the inner surface of the main body 61 is formed in a groove shape that is recessed outward from the main body 61. As described later, when the projection 68 abuts against the rib 36 of the waterproof pan 30, when a strong force is applied to the main body 61 from above, the thin portion 611 is deformed, and the thin portion 611 including the thin portion 611 is deformed. The upper portion from the top constitutes a deforming portion 601 that deforms so that the protrusion 68 that contacts the rib 36 of the waterproof pan 30 approaches the mounting surface 203 of the frame 20. The lower end portion of the main body portion 61 is configured such that the inclination of the inclination with respect to the direction orthogonal to the axis of the main body portion 61 is larger than the portion above the lower end portion of the main body portion 61.

  The central concave portion 62 has a substantially cylindrical portion 621 that extends downward from the periphery of the opening at the upper end of the main body 61 to reach the same position as the lower end of the main body 61 in the vertical direction, and has a predetermined diameter. A portion of the peripheral wall in the direction has a partially enlarged portion 622 with an enlarged diameter. In the partially enlarged diameter portion 622, a through hole 624 is formed that penetrates in the vertical direction (the direction connecting the front surface and the back surface of the paper in FIG. 8). In the central portion of the partially enlarged diameter portion 622 in the radial direction of the central concave portion 62, the outer diameter is smaller than that of the central concave portion 62 from the bottom of the central concave portion 62 in a positional relationship coaxial with the central concave portion 62. The combined cylindrical part 64 extends further downward. The fitting cylindrical part 64 constitutes a fitting part.

  The fitting cylindrical portion 64 is formed in a substantially cylindrical shape with a bottom, and is fitted to a portion of the side surface (circumferential surface) in the diameter direction of the fitting cylindrical portion 64 that coincides with the partial enlarged diameter portion 622. From the upper end of the cylindrical part 64 to the vicinity of the lower end part, a through-hole 641 that connects the inside and the outside of the fitting cylindrical part 64 is formed. At the position of the through hole 641, a hook portion 643 extends upward from the vicinity of the lower end portion of the fitting cylindrical portion 64. A pair of hook portions 643 are provided and extend to the vicinity of the upper end of the through hole 641. The hook portion 643 is provided with a hook portion rib 642. The hook portion rib 642 exists on the outer surface of the hook portion 643 and is located at the center position in the width direction with respect to the extending direction of the hook portion 643, and extends from the upper end to the lower end of the hook portion 643. The hook part 643 constitutes a fitting part.

  A retaining rib 645 is provided at the upper end portion of the fitting cylindrical portion 64 connected to the central concave portion 62. A plurality of retaining ribs 645 are formed at equal intervals in the circumferential direction of the fitting cylindrical portion 64. The retaining rib 645 extends downward from the upper end portion of the fitting cylindrical portion 64 to a predetermined position, and extends outward from the peripheral surface of the fitting cylindrical portion 64 to the fitting cylindrical portion 64. It protrudes. A diametrical rib 646 is provided inside the fitting cylindrical portion 64. The diametrical rib 646 is formed in a plate shape extending in a direction perpendicular to the diametrical direction in which the partial enlarged-diameter portion 622 is formed in the diametrical direction of the fitting cylindrical portion 64, and the fitting cylindrical portion The internal space 64 is divided into two at the axial center position of the fitting cylindrical portion 64.

  The protrusion 68 is provided on the periphery of the opening at the upper end of the main body 61. The protrusion 68 has an oval shape extending in the circumferential direction of the peripheral edge of the opening in a plan view, and is the upper end surface 613 of the main body 61 over the entire circumference excluding the portion of the partial enlarged diameter portion 622. There are several at intervals. The protrusion 68 protrudes upward from the upper end surface 613 of the main body 61, that is, in a direction away from the attachment surface 203 of the frame 20. The protrusion 68 is smaller than the main body 61. The protruding end portion of the protrusion 68 constitutes a pan contact portion that contacts the rib 36 of the waterproof pan 30, and is configured to be crushed when a strong force is applied from the rib 36 by the contact. The protrusion 68 constitutes a deforming part.

Next, positioning and fixing of the waterproof pan 30 with respect to the frame 20 at the time of construction of the bathroom floor structure of the present embodiment will be described.
First, a tool is inserted into two through-holes 201 formed on a part of a side surface (mounting surface 203) facing the short side beam 21D on the side surface of the short side beam 21C constituting the first frame portion of the frame 20. The positioning member 60 is grasped by the operator's hand without using the hook, the fitting cylindrical portion 64 of the positioning member 60 is inserted, and the hook portion 643 is pushed into the internal space of the frame 20. As a result, the hook portion 643 comes into contact with and catches on the inner peripheral surface of the hollow frame 20, and as shown in FIGS. 4 and 5, the bottom portion of the central concave portion 62 connected to the fitting cylindrical portion 64 (see FIG. The positioning member 60 is fixed to the frame 20 with the stepped portion formed by the central concave portion 62 and the fitting cylindrical portion 64 shown in FIG.

  4 and 5, for convenience of explanation, only the short side beam 21C is shown for the frame 20 and only one positioning member 60 is shown, but not only this, Similarly, the positioning member 60 is fixed to the mounting surface 203 two by two for the short side beam 21D and the long side beam 21B constituting the second frame portion arranged to face the short side beam 21C.

  Next, the waterproof pan 30 is inserted between the positioning members 60 fixed to the short side beams 21C and 21D so as to be dropped. At this time, the lower end portion of the rib 36 of the waterproof pan 30 comes into contact with the side surface (slope) of the main body portion 61 of the positioning member 60 from above in FIG. 6, but the main body portion 61 has a truncated cone shape. The lower end of the projection 68 is guided to a position between the positioning members 60 fixed to the short side beams 21C and 21D (downward left direction shown in FIG. 6). Thereby, the bottom end of the protrusion 68 of the waterproof pan 30 slides along the side surface of the main body 61, so that the waterproof pan 30 finally approaches the position positioned by the positioning member 60. .

  Further, by pressing the waterproof pan 30 downward, as shown in FIG. 6, the protruding end portions of the protrusions 68 as the pan contact portions of the positioning members 60 fixed to the short side beams 21 </ b> C and 21 </ b> D are respectively provided. With the ribs 36 provided in the vicinity of the edge of the waterproof pan 30 being in contact with each other, the waterproof pan 30 is disposed between the positioning members 60 fixed to the short side beams 21C and 21D, and the frame 20 The waterproof pan 30 is placed on the outer peripheral portion 21. At this time, also in the positioning member 60 of the positioning member 60 fixed to the long side beam 21 </ b> B, the rib 36 of the waterproof pan 30 contacts the protruding end of the protrusion 68 as the pan contact portion of the positioning member 60.

  At this time, the protrusion 68 of the positioning member 60 is appropriately crushed by being pressed from the rib 36. Further, when the dimensional error due to the variation in the dimensions of the waterproof pan 30 is large and it is impossible to cope with only the protrusion 68 being crushed, the protrusion 68 of the positioning member 60 is pressed from the rib 36, whereby the thin portion of the positioning member 60 611 is deformed, and the projecting end portion of the protrusion 68 is deformed so as to approach the mounting surface 203 of the frame 20 to absorb a dimensional error caused by a variation in the size of the waterproof pan 30. Thus, the protrusion 68 of the positioning member 60 fixed to the short-side beams 21C and 21D comes into contact with the rib 36 as the pan contact portion, and the deformation portion 601 is appropriately deformed. It is positioned at an appropriate position with respect to the frame 20. The waterproof pan 30 is fixed to the frame 20 by the screws 301.

According to this embodiment, the following effects are produced.
In the present embodiment, a bathroom floor structure 10 including a frame 20 and a waterproof pan 30 placed on the frame 20 includes a short side beam 21C as a first frame portion, and a short side beam. And a short-side beam 21D as a second frame portion disposed to face 21C. The short-side beam 21C and the short-side beam 21D each include a positioning member 60 that positions the waterproof pan 30 with respect to the short-side beam 21C and the short-side beam 21D by contacting the rib 36 of the waterproof pan 30.

  As a result, the waterproof pan 30 is positioned relative to the frame 20 by positioning the positioning member 60 provided on the short side beam 21C as the first frame portion and the short side as the second frame portion disposed opposite to the short side beam 21C. Positioning can be performed such that the waterproof pan 30 is sandwiched between the positioning member 60 provided on the side beam 21D. For this reason, the waterproof pan 30 can be easily and appropriately positioned with respect to the frame 20.

  As a positioning method for fixing the waterproof pan 30 to the frame 20, for example, a metal positioning member that is not easily deformed is fixed to a part of the frame 20 in advance by welding or screws, A method of placing the waterproof pan 30 on the frame 20 and moving the waterproof pan 30 on the frame 20 to bring the reinforcing rib 36 of the waterproof pan 30 into contact with a metal positioning member is conceivable. However, in such a method, the metal positioning member is required to have high accuracy, and thus it is difficult to deform it appropriately. Further, it is necessary to secure a clearance for absorbing a dimensional error due to a variation in the dimensions of the waterproof pan 30.

  Therefore, as in the present embodiment, between the positioning member 60 provided on the short side beam 21C and the positioning member 60 provided on the short side beam 21D disposed to face the short side beam 21C. Positioning cannot be performed with the waterproof pan 30 interposed therebetween. In addition, since the metal positioning member must be fixed by welding or screws, a tool is required and installation is troublesome. Further, since the positioning member is made of metal, it cannot be positioned in all directions. Thus, various problems arise.

  However, in the present embodiment, since the waterproof pan 30 can be positioned with respect to the frame 20 so as to be sandwiched between the positioning members 60 as described above, it is easily and appropriately positioned without using a tool or the like. Can do. Further, as described above, when a metal fitting is used, the waterproof pan 30 is placed on the frame 20 and moved on the frame 20. Therefore, the clearance for absorbing the dimensional error due to the variation in the size of the waterproof pan 30. However, in this embodiment, since the waterproof pan 30 is placed on the frame 20 and is not moved on the frame 20, a dimensional error due to a variation in the size of the waterproof pan 30 is absorbed. The clearance for doing so can be minimized. Thus, the problem which arises when using a metal positioning member does not become a problem in the positioning member 60 of this embodiment.

  Further, according to the present embodiment, the positioning member 60 is attached to the attachment surface 203 constituted by the side surfaces of the short side beam 21C as the first frame portion and the short side beam 21D as the second frame portion, respectively. It is fixed to the short side beam 21C and the short side beam 21D, respectively. The positioning member 60 has a deforming portion 601 that deforms so that the protrusion 68 as the pan contact portion of the positioning member 60 that contacts the rib 36 of the waterproof pan 30 approaches the mounting surface 203.

Thereby, since the deformation | transformation part 601 can be ensured largely, when the dimensional error by the dispersion | variation in the dimension of the waterproof pan 30 is large, it can position appropriately by deform | transforming large.

  Further, according to the present embodiment, the positioning member 60 is a fitting portion that can be fitted into the through-hole 201 formed in the short side beam 21C as the first frame portion and the short side beam 21D as the second frame portion. As a fitting cylindrical portion 64 and a hook portion 643. Thereby, the fitting cylindrical part 64 and the hook part 643 as a fitting part can be easily fixed to the short side beam 21C and the short side beam 21D without performing welding or screwing.

As mentioned above, although preferred embodiment of the floor structure 10 of the bathroom of this invention was described, this invention is not restrict | limited to embodiment mentioned above and can change suitably.
For example, in the present embodiment, two positioning members 60 are provided on each of the short-side beam 21C, the short-side beam 21D, and the long-side beam 21B constituting the three sides of the outer peripheral portion 21 in the frame 20. However, it is not limited to this configuration. For example, three or more positioning members 60 may be provided on each side, and two positioning members are provided on each side of the outer peripheral portion 21 constituting the two sides of the short side beam 21C and the short side beam 21D. 60, or two positioning members on each side of the outer peripheral portion 21 constituting the four sides of the long side beam 21A, the long side beam 21B, the short side beam 21C, and the short side beam 21D. 60 may be provided.

  Moreover, the structure of the bathroom which has a floor structure including a frame, a positioning member, etc. is not limited to the structure of the bathroom 1 in this embodiment. For example, the deformation portion is not limited to the configuration of the deformation portion 601 and the protrusion 68 in the present embodiment. The deformation portion may be deformed so that the pan contact portion of the positioning member that contacts the waterproof pan 30 approaches the mounting surface 203.

  In the present embodiment, the waterproof pan 30 is inserted between the positioning members 60 fixed to the short-side beams 21C and 21D constituting the frame 20 so as to be dropped, and the waterproof pan 30 is disposed inside the frame. However, the present invention is not limited to this configuration. For example, a waterproof pan may be attached to the outside of the frame.
