[Prior art]
In a general bathtub, as shown in FIG. 7, a hot water circulation connector 3 attached to the side surface 2 of the bathtub 1 and a hot water supply device (not shown) installed outside the bathroom are connected to a connecting pipe for an outward path. 4 and the return pipe 5 are connected to each other, and hot water is forcibly circulated between the bathtub 1 and the hot water supply device (not shown) via these connection pipes 4 and 5.
[0003]
In the installation work of each of the connection pipes 4 and 5, conventionally, when the forward connection pipe 4 and the return connection pipe 5 are installed, two holes 7 are formed in the bathroom wall 6 (in the illustrated case, the side wall of the unit bath). 8 are inserted into the holes 7 and 8 from the inner surface side (or outer surface side) of the bathroom wall 6, and the outer surface side of the bathroom wall 6 is inserted into the bolt 10. The nut 11 was attached from (or the inner surface side), and the bolt 10 and the nut 11 were fixed to the bathroom wall 6.
[0004]
The forward connection pipe 4 or the return connection pipe 5 is inserted into the through-holes 9 of the bolts 10, respectively. Thereafter, each end of the forward connection pipe 4 and the return connection pipe 5 is circulated in hot water in the bathroom. The connection tool 3 (see FIG. 7) was connected to a hot water supply device (not shown) installed outside the bathroom.
[0005]
However, if the forward connection pipe 4 and the backward connection pipe 5 are installed on the bathroom wall 6 using the bolt 10 and the nut 11 as described above, the hole 7 for the forward connection pipe 4 and the backward connection are provided. Holes 8 for the pipe 5 must be provided at two places on the bathroom wall 6, and the drilling work is difficult when the bathroom wall 6 is thick or the surrounding space of the bathroom wall 6 is narrow.
[0006]
In addition, when the bolt 10 and the nut 11 are attached to the holes 7 and 8 of the bathroom wall 6, two workers are divided into the inside and outside of the bathroom, for example, the workers in the bathroom are bolted to the holes 7 and 8, respectively. 10 is inserted and held, and another worker outside the bathroom screwes the nut 11 into the bolt 10, and one person works while holding the bolt 10 and the nut 11 together to prevent accompanying rotation. The worker had to turn the bolt 10 or the nut 11 and fix it to the bathroom wall 6. Therefore, it takes time to install the forward connection pipe 4 and the backward connection pipe 5 on the bathroom wall 6.
