Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a piping unit which comprises a plurality of pipes housed in a casing and is connected to a room to form an indoor piping system.

(Prior Art) A main pipe connected to a pipe shaft for water and hot water that vertically penetrates a building body is inserted and housed in a casing of a piping unit that is conventionally connected to a room.
In addition, when the piping unit is equipped with equipment such as a urinal, urinal, and handwasher, a pipe for connection with the equipment is also stored.

(Problems to be solved by the invention) However, when a piping unit is connected to a room, a plurality of long main pipes penetrating the entire piping unit are required, but the long pipes are troublesome to handle. Further, the joining work is also troublesome when the pipes provided in the piping unit are joined to form a long main pipe when the piping units are continuously connected.
Further, since the tubular body is a rigid body, it is difficult for a plurality of tubular bodies arranged in the casing to interfere with each other and to set the arrangement position. Furthermore, an elbow, cheese, etc. are required to change the arrangement direction of the pipes, and the number of connection points increases, which easily causes water leakage.

The present invention has been made to solve the above inconvenience,
The purpose is to reduce the thickness of the casing,
An object is to provide a piping unit that is small in size, easy to handle, and easy to perform construction work.

(Means for Solving the Problems) In order to solve the above problems, the present invention relates to a plurality of piping units which are continuously arranged facing a main pipe connected to a pipe shaft in a building body. The frame-shaped structure case formed is provided, the frame is attached to the frame on the front side of the piping unit in the case, and the branch pipe is fixed by horizontally connecting the main pipe to the frame. The branch pipe has a plurality of branched branch ports, and the branch pipes connected to the respective branch ports are connected to a urinal, a urinal, etc. provided on the front surface of the piping unit.

(Operation) According to the above means, unlike the conventional piping unit, it is not necessary to install a long main pipe in the piping unit, and even if the piping units are continuously provided, the pipe bodies are joined to form the main pipe. No need to configure.

(Embodiment) Next, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

Further, 135 is a waste water pipe with a ventilation pipe 137, which is connected to pipes 139, 141 connected to the waste water ports of the urinals t1, t2.

Since the branch pipe used in the above-described embodiment is made of a flexible pipe made of polybutene, cross-linked polyethylene or the like,
Plural pipes can be arranged avoiding each other in the piping unit so as not to interfere with each other, and it does not take time to set the pipe arrangement position, and the construction work can be performed quickly. Further, not only can the branch pipes be joined to each other by using a socket, a push nut, etc., but they can also be easily joined by heat fusion.
Further, since the branch pipe is a flexible pipe, the pipe itself can be easily bent, and since no elbow or the like is required, the number of joints can be reduced and there is no risk of leakage.

(Effect of the Invention) As described above, according to the present invention, it is not necessary to internally install a long main pipe in the piping unit, and even if the piping units are connected in series, the pipes are joined to form the main pipe. Since it is not necessary to do so, the thickness of the casing of the piping unit can be made thin and small, and the indoor piping system can be configured only by connecting the piping units in series. Further, the frame is assembled to form a case of the frame-shaped structure of the piping unit, the frame is attached to the frame on the front side of the piping unit in this case, and the connection port connected to the main pipe is horizontal to this frame for branching. Since the pipe body is fixed, as a preparatory work at the time of construction work, it suffices to arrange a main pipe having a length dimension from a pipe shaft arranged vertically in the building body to a piping unit. Therefore, even when the conventional indoor piping system is modified or redesigned into the piping unit of the present invention, there is no need to perform large-scale preparation work on the pipe shaft and the main pipe side, which is advantageous.
