Summary of the Invention

Problems to be Solved by the Invention

[0005] In the above apron mounting structure, since the fixing member is attached to the apron and then mounted on the washbasin pan, it is difficult to handle when attaching the fixing member to the washbasin pan, making it difficult to construct the bathroom.

[0006] On the other hand, although it is conceivable to attach the fixing member after arranging the apron, in that case, work in a narrow space outside the bathroom is required, and the framework and columns of the building where the bathroom is provided get in the way, still making the construction work difficult.

[0007] Therefore, an object of the present invention is to provide a bathroom that can easily construct a bathroom, a connecting member for a bathroom, and a method for constructing a bathroom.

Means for Solving the Problems

[0008] The bathroom of the present invention includes a floor member serving as a wash area, a bathtub juxtaposed with the floor member in a first direction orthogonal to the vertical direction, an apron provided between the floor member and the bathtub, a floor wall body extending along the vertical direction and the first direction and standing on the floor member, and a connecting member for a bathroom including a first connecting member that connects the apron and the floor wall body. The apron has an apron end portion in a second direction orthogonal to the vertical direction and the first direction. The apron end portion includes an apron end face orthogonal to the second direction and a contact surface provided on the bathtub side in the first direction with respect to the apron end face and orthogonal to the first direction. The floor member has an outer end face located outside the apron end portion in the second direction. The floor wall body has a wall edge portion on the bathtub side in the first direction and juxtaposed with the floor member side in the first direction with respect to the apron end portion. The first connecting member has a concave first accommodation recess that accommodates and fixes the apron end portion and the wall edge portion of the floor wall body. The first accommodation recess has an apron contact portion that is located on the bathtub side in the first direction with respect to the apron end portion and defines a part of the concave shape. The apron contact portion has an apron contact surface that is the inner surface of the concave shape and contacts the contact surface of the apron end portion, and an outer surface disposed on the bathtub side in the first direction with respect to the apron contact surface. The length from the apron contact surface to the outer surface of the apron contact portion is configured to be shorter than the length between the outer end face of the floor member and the apron end face of the apron end portion.

[0009] According to such a configuration, since the length from the apron contact surface to the outer surface of the apron contact portion is shorter than the length between the outer end surface of the floor member and the apron end surface of the apron end portion, in a state where the floor member, the bathtub, and the apron are installed, the bathroom connecting member is approached from the floor member side in the first direction between the apron end surface and the outer end surface of the floor member, and the apron contact surface and the outer surface of the apron contact portion are inserted into the space along the apron end surface and the outer end surface of the floor member. From the inserted state, the bathroom connecting member is rotated around the vertical direction so that the apron contact portion is on the bathtub side in the first direction with respect to the apron end portion and the apron contact surface of the apron contact portion faces the contact surface of the apron end portion, whereby the bathroom connecting member can be installed at a position capable of accommodating the apron end portion of the apron and the wall edge portion of the upper wall body on the floor. Therefore, when constructing a bathroom, the bathroom connecting member can be provided well around from inside the bathroom, so that the construction of the bathroom can be easily performed.

[0010] Further, a bathtub upper wall body provided adjacent to the upper wall body on the floor in the first direction and standing with respect to the bathtub is provided, and the bathroom connecting member includes a second connecting member disposed above the first connecting member and connecting the upper wall body on the floor and the bathtub upper wall body. It can also be configured in this way.

[0011] According to such a configuration, the connection between the upper wall body on the floor and the apron, and the connection between the upper wall body on the floor and the bathtub upper wall body can be made with one bathroom connecting member, so that the connection work can be efficiently performed and the construction of the bathroom can be easily performed.

[0012] Further, the first connecting member and the second connecting member are separate bodies, and the bathroom connecting member can also be configured to include a connecting part that arranges and connects the first connecting member and the second connecting member in the vertical direction.

[0013] According to such a configuration, since the first connecting member and the second connecting member can be connected side by side in the vertical direction by the connecting part, it becomes easy to align the first connecting member and the second connecting member. Therefore, the construction of the bathroom can be easily performed.

[0014] Further, the bathroom connecting member can also be configured to include a bathtub fixing member that can be connected to the bathtub.

[0015] According to such a configuration, since the bathroom connecting member can be connected to the bathtub, the bathroom connecting member can be supported by the bathtub.

[0016] In addition, the bathroom connecting member of the present invention includes a floor member serving as a wash area, a bathtub arranged parallel to the floor member in a first direction orthogonal to the vertical direction, an apron provided between the floor member and the bathtub, and a floor wall body extending along the vertical direction and the first direction and standing upright with respect to the floor member. The apron includes an apron end portion in a second direction orthogonal to the vertical direction and the first direction. The apron end portion includes an apron end face orthogonal to the second direction and a contact face provided on the bathtub side in the first direction with respect to the apron end face and orthogonal to the first direction. The floor member includes an outer end face located outside the apron end portion in the second direction. The floor wall body is a wall edge portion on the bathtub side in the first direction and is provided parallel to the floor member side in the first direction with respect to the apron end portion. It is a bathroom connecting member used in a bathroom, and includes a first connecting member that connects the apron and the floor wall body. The first connecting member includes a concave first accommodating recess that accommodates and fixes the apron end portion and the wall edge portion of the floor wall body. The first accommodating recess includes an apron contact portion that is located on the bathtub side in the first direction with respect to the apron end portion and defines a part of the concave shape. The apron contact portion includes an apron contact face that is the inner face of the concave shape and contacts the contact face of the apron end portion, and an outer face arranged on the bathtub side in the first direction with respect to the apron contact face. The length from the apron contact face to the outer face of the apron contact portion is configured to be shorter than the length between the outer end face of the floor member and the apron end face of the apron end portion.

[0017] According to such a configuration, the length from the apron contact surface to the outer surface of the apron contact portion is shorter than the length between the outer end surface of the floor member and the apron end surface of the apron end portion. Therefore, with the floor member, bathtub, and apron installed, the bathroom connecting member is approached from the floor member side in the first direction between the apron end surface and the outer end surface of the floor member, and the apron contact surface and the outer surface of the apron contact portion are arranged along the apron end surface and the outer end surface of the floor member. Then, the apron contact portion is inserted into the space, and from this inserted state, the bathroom connecting member is rotated around the vertical direction so that the apron contact surface of the apron contact portion faces the contact surface of the apron end portion on the bathtub side in the first direction with respect to the apron end portion. Thus, the bathroom connecting member can be installed at a position capable of accommodating the apron end portion of the apron and the wall edge portion of the floor upper wall body. Therefore, when constructing a bathroom, the bathroom connecting member can be provided well around from inside the bathroom, and thus the construction of the bathroom can be easily performed.

[0018] Further, the method for constructing a bathroom of the present invention includes a step of installing the bathroom connecting member with respect to the structure in a state where the floor member, the bathtub, and the apron are installed. The step of installing the bathroom connecting member includes approaching at least the first connecting member of the bathroom connecting member from the floor member side in the first direction between the apron end surface and the outer end surface, inserting the apron contact portion into the space with the apron contact surface and the outer surface of the apron contact portion arranged along the apron end surface and the outer end surface, and rotating at least the first connecting member of the bathroom connecting member around the vertical direction so that the apron contact surface faces the contact surface on the bathtub side in the first direction with respect to the apron end portion in the inserted state.

[0019] According to such a configuration, by rotating the bathroom connecting member around the vertical direction, the bathroom connecting member can be provided. Therefore, when constructing a bathroom, the apron and the bathroom connecting member can be provided well around, and the bathroom connecting member can be provided from inside the bathroom. Thus, the construction of the bathroom can be easily performed.

Advantages of the Invention

[0020] According to the present invention, it is possible to obtain a bathroom, a connecting member for a bathroom, and a method for constructing a bathroom that can easily construct a bathroom.

The apron contact surface 615a is a surface that extends along the left - right direction and can contact the contact surface 56b of the apron engagement portion 56. The inner surface of the apron - side extension portion 616 in the left - right direction is a surface that extends along the front - rear direction, and the front - side end portion is connected to the inner end portion of the apron contact surface 615a in the left - right direction, which is the apron - side extension surface 616a. The apron - side extension surface 616a faces the apron - facing surface 55a of the apron extension portion 55. The rear - side end surface of the apron - side extension portion 616 is an outer surface 613a that extends in the left - right direction by the thickness of the apron - side extension portion 616. The outer surface 613a and the apron contact surface 615a extend substantially in parallel. Such an apron contact portion 613 contacts the apron end portion 54 and forms a third engagement portion 6C that engages with the apron 5.

[0048] The first wall contact portion 614 includes a first wall contact main body portion 617 that extends inward in the left - right direction from the end portion of the first accommodation base portion 612 on the wash - place side (front side), and a first wall - side extension portion 618 that extends from the end portion of the first wall contact main body portion 617 inward in the left - right direction and extends toward the wash - place side (front side) in the front - rear direction. The first wall contact portion 614 contacts the wall edge portion 42 of the floor upper wall body 4A and forms a first engagement portion 6A that engages with the wall body 4.

[0049] The first wall contact main body portion 617 has a first wall contact surface 617a on its inner surface (rear surface) that defines the inner surface of the concave first accommodation recess 611. The first wall contact surface 617a is a surface that extends in the left - right direction and can contact the wall engagement portion 44. Specifically, the first wall contact main body portion 617 includes an outer portion 6171 that extends inward in the left - right direction from the end portion of the first accommodation base portion 612 on the wash - place side (front side), a front - rear extension portion 6172 that extends rearward from the end portion of the outer portion 6171 inward in the left - right direction, and an inner portion 6173 that extends inward in the left - right direction from the rear - side end portion of the front - rear extension portion 6172.

[0050] The inner surface of the first wall side extending portion 618 in the left - right direction is a surface extending along the front - rear direction, and the rear end portion is connected to the inner end portion in the left - right direction of the first wall contact surface 617a, which is the first wall side extending surface 618a. The first wall side extending surface 618a faces the outer (back) surface of the wall extending portion 43 in the left - right direction.

[0051] As shown in FIG. 10, the second connecting member 62 includes a second accommodating recess 621 for accommodating the wall edge portion 42. The second connecting member 62 is a rod - shaped body whose length in the up - down direction is shorter than the length from the ceiling (not shown) of the bathroom 1 to the flange portion 32, and the cross - section orthogonal to the up - down direction is substantially constant. Further, a hole for fixing (screwing) to a member (not shown) arranged on the ceiling portion is formed at the upper end portion of the second connecting member 62, and a hole for fixing (screwing) to the connecting part 63 is formed at the lower end portion.

[0052] The second accommodating recess 621 includes a plate - shaped second accommodating base portion 622 extending in the front - rear direction and located on the outer side in the left - right direction, and second wall contact portions 623 extending inward in the left - right direction from the front end portion and the rear end portion of the second accommodating base portion 622. The second accommodating recess 621 is concave on the outer side in the left - right direction and defines a second accommodating space capable of accommodating two wall edge portions 42 (wall engaging portions 44) arranged in the front - rear direction. The second accommodating recess 621 of the present embodiment has a symmetric shape in the front - rear direction. That is, the second wall contact portion 623 arranged on the front end side and the second wall contact portion 623 arranged on the rear end side are symmetric in the front - rear direction.

[0053] The configuration of the second wall contact portion 623 is the same as that of the first wall contact portion 614. That is, the second wall contact portion 623 includes a second wall contact main body portion 624 extending inward in the left - right direction from the end portion of the second accommodating base portion 622, and a second wall side extending portion 625 extending toward the washing area side (front side) in the front - rear direction from the inner end portion of the second wall contact main body portion 624 in the left - right direction.

[0054] The second connecting member 62 has a first engaging portion 6A on the front side and a second engaging portion 6B on the rear side that abuts against the wall edge portion 42 of the upper wall body 4B of the bathtub and engages with the wall body 4. The configuration of the first engaging portion 6A is the same as that of the first engaging portion 6A of the first connecting member 61, and the second engaging portion 6B has a shape symmetric to the first engaging portion 6A in the front-rear direction.

[0055] As shown in FIG. 11, the connecting part 63 includes a lower connecting portion 631 connected to the upper end portion of the first connecting member 61, an upper connecting portion 634 connected to the lower end portion of the second connecting member 62, and a connecting intermediate portion 65 extending from the lower connecting portion 631 to the upper connecting portion 634.

[0056] The lower connecting portion 631 includes a plate-shaped lower connecting base portion 632 that extends in the front-rear direction and the vertical direction, and lower connecting side portions 633 that extend inward in the left-right direction from both front-rear end portions of the lower connecting base portion 632. The lower connecting portion 631 is configured to be attachable to the outside of the first housing recess 611 with respect to the first connecting member 61. The lower connecting base portion 632 can abut against the outer surface of the first housing space 61a of the first housing base portion 612, and in a state where the lower connecting base portion 632 abuts, both lower connecting side portions 633 face the outer surface of the apron abutting portion 613 or the outer surface of the first wall abutting portion 614. Further, a hole penetrating in the thickness direction for fixing the upper end portion of the first connecting member 61 (specifically, fixing with bolts and nuts) is formed in the lower connecting base portion 632.

[0057] The upper connecting portion 634 includes a plate-shaped upper connecting base portion 635 that extends in the front-rear direction and the vertical direction, and an upper connecting side portion 636 that extends inward in the left-right direction from one end portion of the upper connecting base portion 635 in the front-rear direction. The upper connecting portion 634 is configured to be attachable to the second connecting member 62 outside the second housing recess 621. The upper connecting base portion 635 can abut against the outer surface with respect to the second housing space of the second housing base portion 622. In a state where the upper connecting base portion 635 abuts, the upper connecting side portion 636 faces the outer surface of one of the second wall abutting portions 623. Further, in the upper connecting base portion 635, a hole penetrating in the thickness direction for fixing (fixing with bolts and nuts) the lower end portion of the second connecting member 62, and a hole for fixing (fixing with bolts and nuts) a bathtub fixing member 64 described later are formed.

[0058] The intermediate connecting portion 65 includes a plate-shaped intermediate connecting base portion 651 that extends continuously in the vertical direction with the lower connecting base portion 632 and the upper connecting base portion 635, an intermediate connecting side portion 652 that extends inward in the left-right direction from the front end portion of the intermediate connecting base portion 651, and a positioning portion 653 connected to the end portion of the intermediate connecting side portion 652 on the inner side in the left-right direction.

[0059] The intermediate connecting base portion 651 is a plate-like body whose width direction length (front-rear direction length) is smaller than that of the upper connecting base portion 635 and the lower connecting base portion 632. In the vertical direction, the intermediate connecting base portion 651 is arranged such that one end portion (front end portion) in the width direction is continuously extended with the one end portion in the width direction of the upper connecting base portion 635 and the lower connecting base portion 632. A notch 65a is formed by the lower end portion of the upper connecting base portion 635, the other end portion (rear end portion) in the width direction of the intermediate connecting base portion 651, and the upper end portion of the lower connecting base portion 632. The notch 65a is formed so as to extend over the entire area of the intermediate connecting base portion 651 in the vertical direction. That is, a notch 65a extending from the lower connecting portion 631 to the upper connecting portion 634 is formed in the intermediate connecting base portion 651. Further, the vertical width of the notch 65a is larger than the thickness (vertical direction length) of the flange body 321.

[0060] The positioning portion 653 is a plate-like body extending in the vertical direction. The positioning portion 653 is configured to extend across the entire area of the intermediate connection base portion 651 in the vertical direction. That is, the positioning portion 653 is a plate-like body extending from the lower connection portion 631 to the upper connection portion 634. Such a positioning portion 653 can abut against the upper end surface of the first connection member 61 connected to the lower connection portion 631 and can also abut against the lower end surface of the second connection member 62 connected to the upper connection portion 634. The positioning portion 653 of the present embodiment is configured to extend along the front-rear direction and can abut against the upper end surface of the first wall abutting portion 614 and the lower end surface of the second wall abutting portion 623. Thus, since the first connection member 61 and the second connection member 62 abut against the positioning portion 653, the first connection member 61 or the second connection member 62 is not located within the range (the entire intermediate connection portion 65) where the positioning portion 653 is located in the vertical direction.

[0061] By the positioning portion 653 of the connecting part 63, the first connecting member 61 and the second connecting member 62 are positioned so as to extend continuously in the vertical direction. Specifically, the first engaging portion 6A of the first connecting member 61 and the first engaging portion 6A of the second connecting member 62 are in a state of extending continuously in the vertical direction. Also, the third engaging portion 6C of the first connecting member 61 and the second engaging portion 6B of the second connecting member 62 are in a state of extending continuously in the vertical direction. Specifically, the third engaging portion 6C and the second engaging portion 6B are arranged such that the apron side joint material abutting surface 56c to be engaged and the wall side joint material abutting surface 441 of the bathtub upper wall body 4B to be engaged are substantially flush in the vertical direction.

[0062] As shown in FIGS. 8 and 16, the bathtub fixing member 64 is fixed to the connecting part 63 and extends from the connecting part 63 toward the bathtub 3 side (rear side). Specifically, the bathtub fixing member 64 includes a connecting and fixing part 641 fixed to the connecting part 63, a connecting and extending part 642 extending from the connecting and fixing part 641 toward the bathtub 3 side, and a bathtub connecting part 643 provided at the end of the connecting and extending part 642 on the bathtub 3 side and abutting against the flange part 32. The connecting and fixing part 641 is fixed to the connecting part 63 with bolts and nuts while abutting against the outer surface in the left - right direction of the connecting part 63 (specifically, the upper connecting part 634). The bathtub connecting part 643 is a plate - like body that can be fitted into the second flange groove 34a and placed on the bottom surface of the second flange groove 34a, and has a hole penetrating in the vertical direction. The bathtub connecting part 643 of the present embodiment is configured to be fixed to the bathtub main body 31 by screwing after overlapping the formed hole with the fixing hole 34b of the second flange part 34. The connecting and extending part 642 is a plate - like body extending from the connecting and fixing part 641 to the bathtub connecting part 643, and connects the connecting and fixing part 641 and the bathtub connecting part 643.

[0063] Here, the distance L3 (see FIG. 9) (equal to the length in the front - rear direction of the apron - side extending surface 616a in the present embodiment) between the outer surface 613a and the apron - abutting surface 615a of the first connecting member 61 is shorter than the distance L1 (see FIG. 12) between the outer end surface 23a of the floor member 2 and the apron end surface 56a. Also, the distance L3 between the outer surface 613a and the apron - abutting surface 615a of the first connecting member 61 is shorter than the distance L2 (see FIG. 12) between the inner surface in the left - right direction of the support standing surface 262 of the support member 26 and the apron end surface 56a.

[0064] As shown in FIG. 1, the wall connecting member 7 is a rod - like body erected on the floor member 2 or the bathtub 3, and is configured to connect adjacent wall bodies 4 (the floor - upper wall bodies 4A or the bathtub - upper wall bodies 4B). The specific configuration of the wall connecting member 7 in the present embodiment is the same as that of the second connecting member 62 of the bathroom connecting member 6, except that it extends from the ceiling to the floor member 2 or from the ceiling to the bathtub 3 and the lower end part is directly connected to the floor member 2.

[0065] A method for constructing the bathroom 1 with the above-described configuration will be described.

[0066] When constructing the bathroom 1, first, the bathtub 3 and the floor member 2 are arranged side by side, and the apron 5 is installed between the bathtub 3 and the floor member 2. Next, as shown in Fig. 12, the support member 26 is arranged on the floor member 2 (engagement groove 23b). When installing the support member 26, the support engagement portion 263 is locked to the outer end portion 23, and the hole formed in the support bottom portion 261 is aligned with the hole formed in the engagement groove 23b and fixed with a screw.

[0067] Next, the bathroom connection member 6 is erected with respect to the floor member 2. The erection of the bathroom connection member 6 to the floor member 2 is performed in (1) an assembly process, (2) an insertion process, (3) a fitting process, and (4) a fixing process.

[0068] (1) The assembly process is a process of connecting the first connection member 61 and the second connection member 62 with the connection part 63 and forming them into a rod shape extending in the vertical direction. In the assembly process, the bathtub fixing member 64 is not connected to the connection part 63.

[0069] (2) The insertion process is a process of inserting the apron end portion 54 into the first accommodation space 61a of the first accommodation recess 611. The insertion process is performed in a state where the entire bathroom connection member 6 is positioned above the support standing surface portion 262 in the vertical direction, that is, in a state where the bathroom connection member 6 is lifted above the support standing surface portion 262. Therefore, the bathroom connection member 6 does not interfere with the support member 26.

[0070] First, in the insertion step, the rod-shaped bathroom connection member 6 is brought close to the apron end 54 from the front side. Next, while rotating the bathroom connection member 6 about the vertical axis, it is moved rearward so that the apron-side extension 616 of the first connection member 61 passes between the apron end face 56a in the horizontal direction and the outer end face 23a of the second outer end 25. Specifically, in the insertion step, the bathroom connection member 6 is brought close to the apron end 54 in a state where the outer surface 613a and the apron contact surface 615a extend substantially parallel, that is, in a state rotated approximately 90 degrees to the left about the vertical axis from the mounted state. As shown in FIG. 14(a), the bathroom connection member 6 is tilted with respect to the apron plate portion 52 in a state where the front surface of the apron plate portion 52 and the first wall-side extension 618 face each other in the front-rear direction, and the apron-side extension 616 is inserted between the apron end face 56a and the outer end face 23a.

[0071] Next, as shown in FIG. 14(b), the bathroom connection member 6 is rotated about the vertical axis so that the apron-side extension 616 approaches the apron extension 55. Specifically, the bathroom connection member 6 is rotated so that the apron contact surface 615a of the first connection member 61 is located deeper than the contact surface 56b of the apron end 54 and faces in the front-rear direction. In the present embodiment, the entire bathroom connection member 6 is rotated while being moved deeper so that the apron engagement portion 56 is received in the first accommodation recess 611. Then, as shown in FIG. 14(c), when the apron-side extension 616 and the apron extension 55 extend substantially parallel and the apron engagement portion 56 is inserted into and received in the first accommodation recess 611, the insertion step is completed. When the insertion step is completed, the bathroom connection member 6 is lowered from the lifted state, and the lower surface of the first connection member 61 comes into contact with the upper surface of the support bottom 261.

[0072] As shown in Fig. 15, when the bathroom connecting member 6 is rotated in the insertion process, the connecting part 63 rotates while avoiding the flange part 32 of the bathtub 3 at the notch 65a. Specifically, as shown in Fig. 15(a), in the insertion process, the connecting part 63 approaches the flange part 32, and then, as shown in Fig. 15(b), it rotates about the vertical axis. Here, when the apron side extension part 616 is located between the apron end face 56a and the outer end face 23a, a part of the first connecting member 61 and a part of the lower connecting part 631 (the lower connecting base part 632 and the lower connecting side part 633) to which the first connecting member 61 is connected are located overlapping the flange part 32 in the vertical direction. On the other hand, since the notch 65a is formed in the middle connecting part 65, the flange part 32 can be avoided at the notch 65a, and interference between the connecting part 63 and the flange part 32 during rotation can be suppressed. Then, as shown in Figs. 15(c) and 18, when the bathroom connecting member 6 further rotates, the flange part 32 is in a state of fitting into the notch 65a. When the rotation is completed, the portions of the lower connecting part and the upper connecting part that overlap the flange part 32 in the vertical direction will be located overlapping the second flange groove 34a. Therefore, the bathroom connecting member 6 can be moved (lowered) downward by the depth of the second flange groove 34a.

[0073] (3) The applying process is a process of bringing the applying surface 56b into contact with the apron contact surface 615a. Specifically, the entire bathroom connecting member 6 is moved forward to bring the applying surface 56b into contact with the apron contact part 613. By this process, the positioning of the bathroom connecting member 6 with respect to the apron 5 in the horizontal direction is achieved.

[0074] (4) The fixing process is a process of fixing the bathroom connecting member 6 to the support member 26. Specifically, the bathroom connecting member 6 is fixed to the support member 26 by screwing from the inside of the bathroom 1.

[0075] Through the above processes, the bathroom connecting member 6 is erected with respect to the floor member 2.

[0076] Next, as shown in FIGS. 16 and 17, a bathtub fixing member 64 is connected to the connecting part 63 of the vertically installed bathroom connecting member 6, and the connected bathtub fixing member 64 is connected to the bathtub 3. Specifically, the bathroom connecting member 6 is approached from the bathtub 3 side to the connecting part 63, overlapped from the outside in the left-right direction on the upper connecting base part 635, and fixed with bolts and nuts from the inside of the bathroom 1. In this state, the hole formed in the bathtub connecting part 643 overlaps with the fixing hole 34b. Then, the bathtub connecting part 643 is screwed to the bathtub 3. In this step, the bathroom connecting member 6 is connected to the bathtub 3.

[0077] Next, the floor wall body 4A is erected on the second outer end part 25, and the bathtub upper wall body 4B is erected on the second flange part 34. When erecting the floor wall body 4A, the lower end part of the wall panel 41 is engaged with the engaging groove 23b, and the wall engaging part 44 is inserted into the first accommodating recess 611 and the second accommodating recess 621. At this time, the apron end part 54 (apron engaging part 56) and the wall edge part 42 (wall engaging part 44) are arranged side by side in the front-rear direction in the first accommodating recess 611. Also, when erecting the bathtub upper wall body 4B, the lower end part of the wall panel 41 is engaged with the second flange groove 34a, and the wall engaging part 44 is inserted into the second accommodating recess 621. At this time, the wall edge part 42 (wall engaging part 44) of the floor wall body 4A and the wall edge part 42 (wall engaging part 44) of the bathtub upper wall body 4B are arranged side by side in the front-rear direction in the second accommodating recess 621. Note that a sealing material is arranged between the engaging groove 23b and the wall panel 41 and between the second flange groove 34a and the wall panel 41.

[0078] Then, a dry joint material is arranged between the apron end part 54 (apron engaging part 56) and the wall edge part 42 (wall engaging part 44) in the first accommodating recess 611 and between the wall edge part 42 (wall engaging part 44) of the floor wall body 4A and the wall edge part 42 (wall engaging part 44) of the bathtub upper wall body 4B in the second accommodating recess 621, and the floor wall body 4A and the flange part 32 and the floor wall body 4A and the bathtub upper wall body 4B are connected.

[0079] In the above steps, the bathroom 1 is constructed.

[0080] According to the bathroom 1 configured as described above, since the length from the apron contact surface 615a to the outer surface 613a of the apron contact portion 613 is shorter than the length between the outer end surface 23a of the floor member 2 and the apron end surface 56a of the apron end portion 54, with the floor member 2, the bathtub 3, and the apron 5 installed, the bathroom connecting member 6 is brought closer from the floor member 2 side in the first direction between the apron end surface 56a and the outer end surface 23a of the floor member 2, and the apron contact portion 613 is inserted into the space with the apron contact surface 615a and the outer surface 613a of the apron contact portion 613 along the apron end surface 56a and the outer end surface 23a of the floor member 2. From the inserted state, the bathroom connecting member 6 is rotated around the vertical direction so that the apron contact portion 613 is on the bathtub 3 side in the first direction with respect to the apron end portion 54 and the apron contact surface 615a of the apron contact portion 613 faces the contact surface 56b of the apron end portion 54, whereby the bathroom connecting member 6 can be installed at a position capable of accommodating the apron end portion 54 of the apron 5 and the wall edge portion 42 of the upper floor wall body 4A. Therefore, when constructing the bathroom 1, the bathroom connecting member 6 can be provided conveniently from within the bathroom 1, so that the construction of the bathroom 1 can be easily performed.

[0081] Also, since the connection between the upper floor wall body 4A and the apron 5 and the connection between the upper floor wall body 4A and the upper bathtub wall body 4B can be made with a single bathroom connecting member 6, the connection work can be efficiently performed, and the construction of the bathroom can be easily performed.

[0082] Furthermore, since the first connecting member 61 and the second connecting member 62 can be connected vertically side by side with the connecting part 63, it becomes easier to align the positions of the first connecting member 61 and the second connecting member 62. Therefore, the construction of the bathroom 1 can be easily performed.

[0083] Also, since the bathroom connecting member 6 can be connected to the bathtub 3, the bathroom connecting member 6 can be supported by the bathtub 3.

[0084] Further, according to the bathroom connecting member 6 of the present embodiment, since the length from the apron contact surface 615a to the outer surface 613a of the apron contact portion 613 is shorter than the length between the outer end surface 23a of the floor member 2 and the apron end surface 56a of the apron end portion 54, with the floor member 2, the bathtub 3, and the apron 5 installed, the bathroom connecting member 6 is approached from the floor member 2 side in the first direction between the apron end surface 56a and the outer end surface 23a of the floor member 2, and the apron contact surface 615a and the outer surface 613a of the apron contact portion 613 are along the apron end surface 56a and the outer end surface 23a of the floor member 2. Insert the apron contact portion 613 into the space in this orientation, and from this inserted state, rotate the bathroom connecting member 6 around the vertical direction so that the apron contact portion 613 is on the bathtub 3 side in the first direction with respect to the apron end portion 54 and the apron contact surface 615a of the apron contact portion 613 faces the contact surface 56b of the apron end portion 54. Thus, the bathroom connecting member 6 can be installed at a position capable of accommodating the apron end portion 54 of the apron 5 and the wall edge portion 42 of the upper floor wall body 4A. Therefore, when constructing the bathroom 1, the bathroom connecting member 6 can be provided conveniently from within the bathroom 1, so that the construction of the bathroom 1 can be easily performed.

[0085] Also, according to the method of constructing the bathroom 1 of the present embodiment, by rotating the bathroom connecting member 6 around the vertical direction, the bathroom connecting member 6 can be provided. Therefore, when constructing the bathroom 1, the apron 5 and the bathroom connecting member 6 can be provided conveniently, and the bathroom connecting member 6 can be provided from within the bathroom 1. Thus, the construction of the bathroom 1 can be easily performed.

[0086] As described above, an example of the embodiment of the present invention has been described, but the present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention.

[0087] For example, the specific configuration of the apron 5 is not limited. For example, the apron 5 can be a single plate body, and the apron engaging portion 56 can be arranged at the end of the plate body.

[0088] In addition, although the bathroom connecting member 6 has been described as extending from the floor member 2 to the ceiling, the present invention is not limited to such a configuration, and it may be configured to extend within a range that does not reach the ceiling from the floor member 2.

[0089] Furthermore, although the configuration in which the wall body 4 and the apron 5 are fixed to the bathroom connecting member with a dry joint material has been described, the present invention is not limited to such a configuration, and it may be configured to be fixed with screws or the like, or fixed with adhesion or the like.

[0090] In addition, although the case where both ends in the left - right direction of the apron are connected to the first connecting member 61 has been described, the present invention is not limited to such a configuration, and it may be configured such that only one end is connected to the first connecting member 61.

[0091] Furthermore, although the case where the first connecting member is asymmetric in the front - rear direction has been described, it may be configured to be symmetric.

[0092] In addition, although the case where the first connecting member 61 and the second connecting member 62 are connected with a connecting part 63 and then erected on the floor member 2 has been described, the present invention is not limited to such a configuration, and it is also possible to erect the first connecting member 61 on the floor member 2 and then connect the connecting part 63 and the second connecting member 62 to the first connecting member 61.
