DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a piping unit which is pre-processed at a factory in accordance with the positions of water supply and drainage equipment and a base pipe in a building, and is carried into a piping place.

[0002]

2. Description of the Related Art Conventionally, a prefabricated pipe using a flexible pipe such as a flexible pipe or a resin pipe is disclosed in, for example, Japanese Patent Application Laid-Open No. Hei 4-25885.
No. 89 describes a prefabricated piping method shown in FIGS. 6, 7 and 8. In this plumbing method, a cheese joint 2 is provided in the middle of the main pipe 1 and a branch pipe 3 is connected to a branch pipe of the cheese joint 2 as shown in FIG. Then, a prefabricated pipe is formed in a factory, and the pipe is rounded to an appropriate radius of curvature as shown in FIG. This construction method is adopted as a construction method capable of quickly performing a piping facility without requiring skilled work at a piping site.

[0003]

However, in this method, for example, in the prefabricated pipe shown in FIG. 7, a cheese joint 2 is provided on the main pipe 1 so that the branch pipes 3 and 4 connected to the water supply / drainage device extend in a direction perpendicular to the main pipe 1. Therefore, when it is rolled as shown in FIG. 8, a protruding tube is formed, and it is not compacted. For this reason, the unity, packing, transport, and transport operations of the units are bulky and inefficient, resulting in poor workability. In addition, loading and unloading work on trucks and transport and handling of units at the construction site are bulky and workability is poor. SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and to provide a prefabricated piping unit which can be easily packaged and compactly assembled, has a high transportation efficiency, and can be easily handled during piping work.

[0004]

SUMMARY OF THE INVENTION The gist of the present invention is to provide a piping unit which is pre-connected at a factory in accordance with the positions of water supply and drainage equipment and a base pipe in a building, and is carried into a piping place.

The prefabricated piping unit is characterized in that the plurality of secondary side branch pipes are connected to the branch pipe of the header composed of pipes, and are wound into a size suitable for the conveyance.

[0005] Further, in a piping unit which is previously connected at a factory in accordance with the location of water supply / drainage equipment and a base pipe in a building, and is carried into a pipe place, the main pipe and the main pipe are separated from the base pipe. A primary pipe connected to a header consisting of a plurality of branch pipes erected on the outer peripheral surface of the main pipe at an axial interval is provided by a flexible pipe, and the flexible primary pipe and the water supply / drainage are provided. A plurality of flexible secondary branch pipes connected to equipment are connected via the header, and the flexible primary pipe and the flexible secondary branch pipe are directed in the same axial direction. A prefabricated piping unit characterized by being connected.

In the above prefabricated piping unit, an elbow joint is connected to the main pipe of the header, and the plurality of flexible secondary side branch pipes are connected to a branch pipe of the header. In the above, a prefabricated piping unit is characterized in that a branch pipe of a cheese joint is connected to a main pipe of the header, and the plurality of flexible secondary side branch pipes are connected to a branch pipe of the header. Further, in the above prefabricated piping unit, a joint for connecting to the plumbing equipment is connected to an end of the flexible secondary branch pipe connected to the branch pipe of the header. Further, in the above, the prefabricated piping unit is characterized in that the header is made of a resin header.

[0007]

According to the present invention, the flexible secondary branch pipe is connected to the branch pipe of the header, so that the entire flexible secondary branch pipe is formed in a unit oriented in the same axial direction. .
Also, a primary side pipe of the header and a plurality of secondary side branches connecting the header to the equipment are formed in a unit connected in the same axial direction. For this reason, it is easy to round and bind the prefabricated pipes, and there is no portion of the pipe that protrudes in the rounded unit, so that the unit can be compactly stored. Therefore, it can be efficiently packed by being rounded into a donut shape. Also, the storage area of the unit is small, the work efficiency at transportation and piping sites is good, and the prefabricated piping is easy to unpack and assemble at the piping site.
