Description

  The present invention relates to a pipe support device that fixes a pipe (for example, a gas flexible pipe) through which a fluid such as city gas flows to a pipe support target such as a wall surface.

  Conventionally, gas flexible pipes have been used for gas indoor piping. A flexible pipe has a smaller mass than a steel pipe and can be bent freely so that it is excellent in workability. When the flexible pipe is fixed on the wall surface, for example, a pipe fixing bracket 6 as shown in FIG. 9A is used. According to the pipe fixing bracket 6, the pipe fixing bracket 6 is screwed onto the pipe supporting target W while maintaining the state where the flexible pipe P is sandwiched between the pipe supporting target W and the pipe fixing bracket 6 at the place where the pipe is to be fixed. I have to stop it. For this reason, an operator who supports the flexible pipe P and the pipe fixing bracket 6 and an operator who fastens the screw are necessary, and the work must be inefficient.

  Therefore, a pipe fixing bracket 7 as shown in FIG. 9B has been proposed and put into practical use as a pipe fixing bracket that can be easily fixed to a wall surface even by one worker. The pipe fixing bracket 7 has a substantially U-shaped cross section including a pair of support pieces 71 that elastically tightly hold the pipe P and a seat 72 that connects one end of the support pieces 71 to each other. It is a formed member. According to the pipe fixing bracket 7, the pipe fixing bracket 7 is fixed in advance to a position where the pipe P of the pipe support target W is to be fixed, and finally the pipe P is fixed by simply pushing the pipe P into the pipe fixing bracket 7. Therefore, it is possible to efficiently fix the piping with a small number of workers. However, even in the case of the pipe fixing bracket shown in FIG. 9 (b), when an external force in the direction of detachment is applied to the pipe P, the pipe may not be sufficiently held, and the cited document is used to solve the problem. In FIG. 1, a pipe fixture 8 shown in FIG. 9C is proposed. The tube fixture 8 includes an arcuate holding piece 81 that is movable in the circumferential direction, a locking portion 82 that locks the movement of the holding piece in the circumferential direction, and a fixing seat 83 connected thereto. The pipe can be supported and fixed easily and firmly.

Japanese Patent Laid-Open No. 07-145878

  As described above, in the pipe fixing bracket of FIG. 9 (b), the pipe is supported and fixed only by the elasticity of the support piece, so that the pipe comes off when an external force is applied in the direction in which the pipe is released. There is a fear. In addition, when the pipe fixing bracket is exposed to a high temperature such as a fire, the pipe fixing bracket may be softened and the pipe cannot be supported. In addition, in the tube fixture shown in FIG. 9C, the tube fixture provided with the movable holding piece and the locking portion is made of synthetic resin so as to make the holding piece movable, and is burned down in the event of a fire to hold the pipe. There is a problem that you can not.

  Therefore, the present invention has been made in view of the above-described problems of the prior art, and can easily fix the pipe to the pipe support target, and an external force acts in the direction in which the pipe is detached or when a fire occurs. An object of the present invention is to provide a pipe support device capable of supporting and fixing a pipe even when placed in a high temperature environment.
