Next, a construction method for the bathroom 1 will be described.

First, as shown in FIG. 1, the bathtub 10 and the washing space floor 20 are installed at predetermined locations. Then, two bathtub-side corner posts 40A, two washing-place-side corner posts 40B, two bathtub-side flat posts 40C, and one washing-place-side flat post 40D are arranged in predetermined positions in the vertical direction. Then, the lower ends of the two bathtub-side corner posts 40A, the two washing-place-side corner posts 40B, the two bathtub-side flat posts 40C, and one washing-place-side flat post 40D are brought into contact with the upper surface of the wall mounting portion 50. . Then, two bathtub-side corner posts 40A, two washing-place-side corner posts 40B, two bathtub-side flat posts 40C, and one washing-place-side flat post 40D are connected to the vertical wall portion 60 of the wall mounting portion 50. As shown in FIG. 10, one side 43A of a window frame fixing angle 43 having an L-shaped cross section is attached to each of the two bathtub-side corner posts 40A. , and screwed to each bathtub-side corner post 40A using a screw S1 (see FIG. 10). The other side 43B of each window frame fixing angle 43 extends away from the bathtub 10 in a direction perpendicular to the one side 43A. In addition, the other side 43B of each window frame fixing angle 43 is arranged so as to be flush with the surfaces on which the bathtub side corner posts 40A face each other.
Next, the upper ends of two bathtub-side corner posts 40A, two washing-place-side corner posts 40B, two bathtub-side flat posts 40C, and one washing-place-side flat post 40D are connected to each other with a plurality of ceiling connecting members 45.

Next, a wall member mounting process is performed. Specifically, as shown in FIG. 2, the corner post 40B on the side of the washing area is attached to at least one of the corner posts 40B on the side of the washing area by sandwiching the corner post 40B on the side of the washing area between two wall members 30. As shown in FIG. The lower end of each wall member 30 is arranged so as to abut on the upper surface of the wall mounting portion 50 on the floor 20 side of the washing space. By attaching the two wall members 30 to at least one of the corner posts 40B on the side of the washing area, not only one corner post 40B on the side of the washing area but also all the column members 40 can be made less inclined. In other words, in the wall member mounting step, the two wall members 30 are attached to each other with at least one of the wash-place-side corner posts 40B not adjacent to the window 70 adjacent to the wash-place-side corner post 40B. Attach to In addition, since the two wall members 30 are separated from the bathtub-side corner post 40A by a predetermined distance, the window 70 and the two wall members 30 do not come into contact with each other when the window 70 is handled in the window mounting step described later. This reduces the chances of the window 70 or the two wall members 30 being scratched.

Then, as shown in FIG. 3, a curing member C is arranged so as to cover the entire upper surface of the bathtub 10. As shown in FIG. More specifically, the curing member C is made of corrugated cardboard having a rectangular shape and an elongated hole in the center. Then, a pair of sleepers W are hung over the pair of longitudinal flanges 12 of the bathtub 10 on the upper surface of the curing member C. As shown in FIG. The sleepers W are made of foamed resin, wood, or the like, for example. Then, two flat spacers 14 made of synthetic resin are attached to the inner surface of the bathroom 1 of the vertical wall portion 60 of the wall mounting portion 50 located on the side of the bathtub 10 separated from the floor 20 of the washing area. These spacers 14 have their lower ends in contact with the upper surface of the wall mounting portion 50, as shown in FIGS. The upper ends of these spacers 14 are substantially flush with the upper ends of the standing wall portions 60 . These spacers 14 adjust the inclination of the window 70 in the vertical direction so that it is vertical, and when the window 70 is placed on the flange portion 12 in the longitudinal direction of the bathtub 10, the window 70 is excessively positioned outside the bathroom 1. It is something that suppresses eating out.

Next, a window preparation step is performed to prepare a window 70 around which four PP bands 77, which are band-shaped cord-like objects, are wound in advance. As shown in FIG. 4, four PP bands 77, which are band-shaped cord-like objects, are wound around the window 70 in advance. These PP bands 77 are wrapped around the window 70 at the factory where the process of attaching the glass plate 75 to the frame 76 is performed, and are packed and shipped together with the window 70 at the factory so that they cannot be seen from the outside. These PP bands 77 are wrapped around the window 70 until the window 70 is placed at a predetermined position on the flange portion 12 of the bathtub 10 . These PP bands 77 are wound around the upper frame 73 and the lower frame 74 of the window 70 via a cushion M or the like along the left frame 71 and the right frame 72 . Two PP bands 77 are arranged near the left frame 71 and the right frame 72, respectively. By doing so, it is possible to suppress deformation of the upper frame 73 and the lower frame 74 of the window 70 due to the tension of the PP band 77 when the worker grips the PP band 77 . The PP band 77 is removed after the window 70 is installed. That is, the PP band 77 is vertically wound around the window 70 along the left frame 71 and the right frame 72 before the construction is completed.

Then, a window placement step is performed. First, as shown in FIG. 4, the operator holds the PP band 77 wrapped around the window 70, places the lower frame 74 of the window 70 on the lower side, and places the upper frame 73 on the upper side of the sleeper W. Place the window 70 on the .

In this manner, the bathroom 1 has a structure in which the longitudinal flange portion 12 of the bathtub 10 supports the window 70 having the frame 76, and the installation of the window 70 is easy. In addition, the construction method of the bathroom 1 can facilitate transportation and installation of the window 70 by gripping the PP band 77 by the worker who constructs the window 70 . Moreover, since the construction method of the bathroom 1 is to place the window 70 on the flange portion 12 in the longitudinal direction of the bathtub 10 from the inside of the bathroom 1, the bathroom 1 can be constructed without being affected by the situation outside the bathroom 1. can be done.

Further, in the construction method of the bathroom 1, the operator who constructs the window 70 grasps the PP band 77, so that the window 70 can be easily transported and installed.

Moreover, since the construction method of the bathroom 1 is to place the window 70 on the flange portion 12 in the longitudinal direction of the bathtub 10 from the inside of the bathroom 1, the bathroom 1 can be constructed without being affected by the situation outside the bathroom 1. can be done.

Therefore, the bathroom 1 of the present invention can be easily assembled, and the construction method of the bathroom 1 of the present invention can easily assemble the bathroom 1 .

Also, the window 70 is supported by the flange portion 12 over the full width of the bathtub 10 in the longitudinal direction. Therefore, since the bathroom 1 can be configured with the window 70 over the entire width of the flange portion 12 in the longitudinal direction of the bathtub 10, installation of the large window 70 is easy.

In addition, the construction method of the bathroom 1 includes two bathtub-side corner posts 40A and two washing-place-side corner posts 40B extending vertically at four corners of the bathroom 1, and each bathtub-side corner post 40A and each washing-place-side corner post. Four ceiling connecting members 45 that connect the upper ends of 40B to each other are provided, and at least one of the washing place side corner posts 40B that are not adjacent to the window 70 is sandwiched before the window mounting process. A wall member attaching step is provided for attaching the two wall members 30 to the corner post 40B on the washing area side. For this reason, the two wall members 30 make it difficult for the washing place side corner post 40B to which the two wall members 30 are attached to fall down. Further, since the bathtub-side corner posts 40A and the washing-place-side corner posts 40B are connected by a plurality of ceiling connecting members 45, the bathtub-side corner posts 40A and the washing-place-side corner posts 40B to which the wall member 30 is not attached. can also make it harder to fall. As a result, even if the window mounting process is performed after the wall member mounting process, the weight of the window 70 can prevent the bathtub side corner posts 40A and the wash area side corner posts 40B from falling down.
