  However, in the configuration of Patent Documents 1 and 2, the number of parts for fixing the stop cock on the floor is large, and the construction at the site becomes complicated. In addition, despite the fact that it is installed in a publicly visible place, the number of parts for fixing the stop cock on the floor is large. It becomes a factor to lose. As a countermeasure against this, in the configuration of Patent Document 2, a cover member that accommodates the pedestal member is provided. However, this increases the number of parts and further complicates on-site construction.

  The present invention has been made in view of such a background, and is intended to provide a tubular body connection device that has a simple configuration, can improve the degree of freedom in shape and design, and is easy to construct. Is.

  A tubular body connection device according to one aspect of the present invention is a tubular body connection device that is installed in a structure and to which a tubular body is connected, and an apparatus main body having a cylindrical portion in which a flow path is formed. A cylindrical mounting member that is attached to the cylindrical portion and through which the tubular body is inserted, and a flange-shaped seat member that is installed in the structure, the cylindrical portion facing the mounting member A surface is provided, and the inner peripheral portion of the seat member is interposed between the opposing surface of the cylindrical portion and the mounting member.

  The tubular body connection device includes a device main body having a tubular portion, an attachment member attached to the tubular portion, and a seat member fixed to a structure such as a floor or a wall. And the inner peripheral part of a seat member is interposed between the opposing surface of a cylindrical part, and an attachment member. Therefore, the tube connection device having the fixing seat can be easily configured. As a result, the number of parts can be reduced, and construction on site can be facilitated.

  Further, as described above, the tube connecting device has a simple configuration with a small number of parts. Furthermore, the seat member that serves as a fixing seat is held with a simple configuration in which an inner peripheral portion thereof is interposed between the opposing surface of the cylindrical portion and the mounting member. Therefore, it is possible to increase the degree of freedom of the shape of the tube connecting device (particularly the device main body that is visible to the human eye) installed in a place where it can be seen, and to improve the design, such as reducing the unevenness on the surface. be able to.

  In addition, since the opposing surface is provided on the cylindrical portion, the seat member can be positioned with respect to the cylindrical portion by the opposing surface. Therefore, the positioning of the seat member with respect to the tubular portion is facilitated. Further, it is easy to hold the seat member by interposing the inner peripheral portion of the seat member between the facing surface of the tubular portion and the mounting member.

  Thus, according to the present invention, it is a simple structure that can reduce the number of parts, can increase the degree of freedom in design and design, and is easy to perform on-site construction. An apparatus can be provided.

  Moreover, the tube body connecting device may further include a rotation preventing means for preventing the seat member from rotating in the circumferential direction with respect to the device main body. In this case, the rotation of the seat member interposed between the opposing surface of the cylindrical portion of the apparatus main body and the mounting member can be suppressed by the rotation preventing means. As a result, construction at the site, that is, an operation of fixing the seat member to the structure, an operation of assembling other members to the tube connecting device fixed to the structure, and the like are facilitated.

  Further, the cylindrical portion is provided with an insertion confirmation portion for confirming the insertion state of the tubular body, and the insertion confirmation portion is disposed on the opposite side of the tubular portion from the insertion side of the tubular body with respect to the seat member. It may be. In this case, the insertion confirmation portion can easily confirm the insertion state of the tube on the opposite side of the tubular portion of the apparatus body from the tube insertion side rather than the seat member fixed to the structure. For example, the insertion confirmation unit can easily confirm the insertion state of the tubular body on the floor if the structure is a floor body, or indoors if the structure is a wall body. Thereby, after construction, even a person other than the construction person can easily confirm the insertion state of the tubular body with the insertion confirmation unit.

  In addition, as a pipe body connection device, for example, a water stop cock, a joint, a valve, a device combining these, etc. are fixed to a structure (for example, a floor body, a wall body, etc.) and one or a plurality of pipe bodies are connected. Including all of the devices used.
