Description

[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention connects a bathtub and a bath kiln, which are installed with a side wall of the bathroom, between them. To attach a circulation pipe for circulating hot water through the side wall The structure and bushing for mounting to facilitate the construction work. It is a thing.

[0002]

[Prior art]

  When installing a bath kiln outside the bathroom when constructing a bathroom, The circulation pipe for circulating hot and cold water must be installed by penetrating the side wall. I won't.

[0003]   For example, as shown in FIG. 9, the bathtub 1 is placed on the waterproof pan 9 placed on the body floor surface 90. The bathroom is installed and the side walls 2 made of tile panels are erected on the four circumferences of the waterproof pan 9. When installing the bath kiln 70 outside the bathroom while building the Then, the circulation pipe 6 that connects the bathtub 1 and the bath kiln 70 is connected to the body wall portion 4 and the side. It must be mounted by penetrating the wall 2.

[0004]   Therefore, normally, as shown in an enlarged view in FIG. 10, an opening having a large opening is formed in the body wall portion 4. 5, the side wall 2 of the bathroom has an opening slightly larger than the diameter of the circulation pipe 6. 3 is provided, and the gap between the opening 3 of the side wall 2 and the circulation pipe 6 inserted therethrough is putty or the like (see FIG. A construction means of filling with (not shown) is adopted.

[0005]

[Problems to be solved by the device]

  In the above construction means, the closed state of the opening 3 of the side wall 2 is ensured and at the same time the To reduce the work load by reducing the amount of filler used, such as It is desirable to provide 3 with the smallest possible diameter and with high positional accuracy. But Naga Select the optimum location on the side wall 2 and provide the aperture 3 with the minimum required size with high precision. It is extremely difficult to do this.

[0006]   Moreover, in order to enhance the hot water circulation efficiency between the bathtub 1 and the bath kiln 70, the upper circulation The pipe 6a has a slight upward slope toward the bathtub 1, and the circulation pipe 6b at the lower part is reversed. It must be mounted with a slight downhill slope towards bathtub 1. Therefore , An error occurs in the opening position of the opening 3 or the relative positional relationship between the bathtub 1 and the bath kiln 70. If it does, not only cannot the circulation pipe 6 be given an appropriate slope, The circulation pipe 6 may not be attached.

[0007]   Therefore, the circulation pipe 6 can be surely attached based on the construction means. In order to prevent an error, an opening 3 having an unnecessarily large size is provided in the side wall 2. It shouldn't be. However, this would increase the amount of filler such as putty used. Not only does this impose a heavy burden on the construction work, but it also reduces the water blocking performance in the openings 3. The problem arises.

[0008]   Further, the construction company such as the side wall 2 and the waterproof pan 9 in the bathroom and the bathtub 1 The contractor who arranges the circulation pipe 6 between the bath kiln and the bath kiln 70 is generally separate. . Therefore, after the former has completed the standing of the side wall 2, the latter forms the opening 3 in the side wall 2. After forming the circulation pipe 6, the former is again used to finish the opening 3 with putty. It is necessary to connect the contractors, such as raising work. But this As it is complicated and very inefficient for the contractors to work alternately, This has led to a delay in numbers.
