In the piping equipment for the fire extinguishing sprinkler arranged in the ceiling, several branch pipes are branched from the main pipe by a branch joint, and the pipe from the branch pipe to the end sprinkler head 8 is a steel pipe. It is made by using a plurality of or a plurality of straight pipes A and elbow joints B, which are cut to about 30 to 60 cm, and joining them appropriately. The pipe from the branch pipe to the end sprinkler head 8 is commonly referred to as unwinding pipe, and the pipe to which the sprinkler head 8 at the end of the unwinding pipe is attached is a sprinkler head attachment pipe (hereinafter referred to as attachment pipe) C. . The mounting pipe C in this case is a straight pipe, and by fixing it with a sprinkler head mounting pipe fixing device (hereinafter referred to as a mounting pipe fixing device), the sprinkler head 8 is held at a predetermined position. Arrangement work of the unwinding pipe is performed by a somewhat skilled plumber (referred to as unwinding plumber).

Further, in the conventional mounting pipe fixing device, since a steel pipe which is a rigid body is used for unwinding pipes, when the steel pipe is arranged, a predetermined position is secured without fixing with a metal fitting. Therefore, the fixing strength is not so much a problem. That is, a supporting metal fitting D having a substantially U-shaped cross section and extending in the longitudinal direction and a strip-shaped steel plate are bent into a substantially U-shape, and the vicinity of the tips of the opposing surfaces are cut out in a substantially semicircular shape to form a hooking portion Eb. It is formed of a fixing metal fitting E provided with a set screw portion Ea on the surface sandwiched between the opposed surfaces. The support metal fitting D has a plurality of ceiling material holding metal fittings 9, 9 arranged at predetermined intervals on the back of the ceiling, and both end portions in the longitudinal direction are passed over, and both end portions are commercially available. Mounting bracket 10,1
It is attached to the ceiling material holding brackets 9, 9 by 0. As for the fixing bracket E, while holding the support bracket D with the set screw part Ea in contact with the support bracket D, hook the mounting pipe C with the hook part Eb protruding to the opposite side of the set screw part Ea and tighten the set screw. The fitting pipe C is pulled and fixed to the support fitting D by.

By the way, the fire extinguishing sprinkler is usually arranged at the stage of performing interior construction at the time of building a building, but at that time, there is a relation with other interior construction,
Often intensive in a short period of time. For that purpose, it is necessary to secure a large number of unwinding plumbers, but in recent years, there is a shortage of unwinding plumbers due to reasons such as aging, and there is a problem in that there is a delay in installation work, and thus in interior work. there were. Also, simplification of the unwinding piping work has been desired. Therefore, recently, from the viewpoint of labor saving and workability,
Instead of using the straight pipe A and elbow joint B for the unwinding pipe, flexible pipes that can be bent have been used. In that case, the attachment pipe at the end of the unwinding pipe is, for example, a 90 ° bend pipe including a straight pipe portion and a bent portion,
The straight pipe portion is fixed by the mounting pipe fixing device.
