Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a piping method for a fluid pipe for supplying a fluid to a device such as a faucet or a sprinkler head, and a pipe fixing member.

[0002]

2. Description of the Related Art FIG. 12 is a perspective view showing a conventional piping method for fluid pipes. In the figure, reference numeral 1 is an unwinding pipe for supplying pressurized water for extinguishing water to a sprinkler head 2, and 3 is a tip of the unwinding pipe. The metal pipes 4 provided are fixing hardware for fixing the metal pipe 3 to the fixed pipe channel 5. Unwinding tube 1
Will be fixed after the completion of the lightweight steel construction of the building. That is, a hanging bolt (not shown), a supporting channel 6, a ceiling base channel 7, and a fixed pipe channel 5
After mounting the fixed metal fitting 4, the fixed metal fitting 4 is mounted at the sprinkler mounting position of the fixed channel 5 for piping, the metal pipe 3 is mounted on the fixed metal fitting 4, and the thumbscrew 4a provided at the end of the fixed metal fitting 4 is tightened with a tool. Unwind tube 1 by raising
Is integrally supported and fixed to the fixed channel 5 for piping.

In order to attach the sprinkler head to the unwinding pipe 1, first, a water thread (mizite) for setting the position and height of the sprinkler head 2 is stretched, and the position and height of the sprinkler head 2 are adjusted. Pipe material is measured, cut, screwed and screwed
After forming the ceiling base board 9 and the finishing board 10, the sprinkler head 2 is completely attached to the pipeline 8.

Further, as a construction method other than the above piping construction method,
Steel pipe pre-attachment method for attaching sprinkler head for pre-installation at the same time as unwinding pipe, flexible metal pipe and pre-attached sprinkler via branch joint (header) such as drum type instead of the steel pipe There is a header construction method that combines heads. These construction methods are new construction methods aimed at labor saving and labor saving by attaching even the sprinkler head before board attachment work.

[0005]

Since the conventional piping method for fluid piping is constructed as described above, the unwinding pipe 1
Is fixed two-dimensionally in the height direction according to the finished surface of the ceiling or in the position direction according to the joints of the ceiling. For example, a mistake in the ceiling finishing dimension, unevenness of the ceiling finishing surface (unevenness), and specification change of the finishing board ( When architectural factors such as thickness) and piping factors such as unwinding pipe processing and construction errors occur, there is a problem that it is impossible to change the height and position to follow them.

The above-mentioned architectural factors and piping-related factors not only occur many times, but are also discovered at the stage of mounting the sprinkler head. It had to be redone, which was time consuming and costly. This is a drawback that also occurs with pre-attached heads. Especially in the case of a sprinkler head, since the mounting height is specified in accordance with the technical standards of the Fire Service Act, the water discharged from the sprinkler at the time of a fire does not reach the specified range when it is installed so that it is buried in the ceiling, It will be a serious problem in terms of disaster prevention. Therefore, if the position of the sprinkler head deviates from the specified position, it will be rectified.

The present invention has been made in order to solve the above problems, and it is possible to easily adjust the height of a fluid instrument such as a sprinkler head from the indoor side with reference to the ceiling finish surface. An object of the present invention is to provide a piping construction method for a fluid pipe and a pipe fixing member which can be formed and therefore eliminates the need to redo the whole or a part of the ceiling to perform the piping work again.
