Japanese Patent Laid-Open No. 11-230421 JP 2002-39442 A Japanese Patent Laid-Open No. 2005-9552 JP 2011-7260 A

  Piping installed in the building is placed in the back of the ceiling, under the floor, and in a narrow space in the wall, and it is necessary to hold and fix the pipe accurately. There was a problem that it was performed in a difficult situation.

  For this reason, in order to improve workability, the invention disclosed in the above patent document has been made, but the band piece that holds the pipe is finally fixed with bolts and nuts, and both hands are held in a narrow space. It was very difficult to put in and work.

  For this reason, this invention is providing the piping suspension band mechanism which can perform the holding | maintenance and fixing operation | work of piping easily also in a narrow space.

  Therefore, the present invention provides a pipe suspension band mechanism for fixing a pipe to a suspension bolt extending from a part of a wall forming a pipe installation space, and a pipe fixing band mechanism for fixing the pipe, and the pipe A band fixing mechanism for fixing the fixing band mechanism to the suspension bolt, and the pipe fixing mechanism is connected to the first arcuate part having a wide area in contact with the pipe and the first arcuate part. A first band piece provided with a first linear portion provided, and the first band piece coupled via a hinge disposed at a position shifted from a position facing the suspension bolt; And a second band piece having a second arcuate portion having a narrow area in contact with the second arcuate portion and a second linear portion connected to the second arcuate portion, and the pipe is connected to the first arc And fix to the second arcuate part It is to comprise a pipe fixing mechanism for.

  In this way, a drop-shaped pipe fixing band mechanism is formed by the first and second band pieces connected via the hinge located at a position shifted from the position where the suspension bolt is opposed. As a result, when the pipe is temporarily arranged in the first arcuate portion having a wide basin that contacts the pipe of the first band piece and then fixed with the second band piece, the first and second band pieces Since it is in the shape of a droplet, it is not perfect for the pipe, so it is easy to fix the pipe. Furthermore, since the pipe is fixed by the pipe fixing mechanism, the mounting work can be easily performed.

  Further, the band fixing mechanism is integrally formed at the tip of the first linear portion of the first band piece, and a first plate portion in which a through hole through which the suspension bolt passes is formed, A pair of extending portions integrally formed at the tip of the second linear portion of the two band pieces and extending on both sides of the suspension bolt, and a meshing claw formed at each of the tips of the pair of extending portions It is desirable that the second plate portion includes a portion.

  Thus, when the second band piece is mounted, the meshing claw portion of the second plate portion formed at the tip of the second linear portion of the second band piece is moved to the end of the first plate portion. Since it can be mounted by engaging with the part and placed so as to overlap the first plate part fixed to the suspension bolt, it is easy to mount, and it is firmly fixed by holding both of them with a nut Is something that can be done.

  Further, it is desirable that the pipe fixing mechanism is constituted by a protruding piece that integrally protrudes from the first plate portion in the extending direction of the pipe, and a pipe holding rod that extends from the protruding piece in the piping direction. . As a result, the pipe can be reliably fixed.

  Furthermore, the band fixing mechanism includes a first plate portion that is formed with a through-hole through which the suspension bolt passes, is fixed to the suspension bolt, a pair of extension portions that extend on both sides of the suspension bolt, and And a second plate portion having a meshing claw portion formed at each of the distal ends of the pair of extending portions, and the first plate portion is located with respect to the distal end of the first linear portion. It is desirable that the second plate portion is rotatably fixed to the tip of the second linear portion.

  According to this structure, since the first band piece and the second band piece can be inclined with respect to the suspension bolt, it is possible to easily perform the piping installation work even when the suspension bolt and the piping are not vertical. It can be done.

  In addition, the pipe fixing mechanism includes a protruding piece that protrudes integrally between the first linear portion and the first plate portion in the extending direction of the pipe, and a pipe that extends from the protruding piece in the piping direction. It is desirable to be constituted by a holding rod.

  According to this structure, since the length of the pipe holding rod can be shortened, the first band piece and the second band piece can be easily inclined.

  Further, the pipe fixing mechanism includes a fixing plate part provided on a second linear part of the second band piece, and a pipe pressing rod penetrating the fixing plate part and the second linear part. Desirably configured.

  According to this structure, since the pipe holding rod is provided on the second band piece, the structure can be simplified.

  Furthermore, it is desirable that the pipe fixing mechanism is an elastic member provided inside the first linear portion. Furthermore, it is desirable that the pipe fixing mechanism is formed by an elastic member having a pipe pressing portion that is fixed at one end inside the first linear portion and protrudes in an arc shape at the other end side. Accordingly, the piping can be pressed by the elastic member only by mounting the second band piece.

  According to the present invention, since the band for fixing the pipe is not circular but has a drop shape, the band piece for fixing the pipe can be easily attached. In addition, since the tip of the second band piece is formed so as to avoid the suspension bolt by the two extending parts and can be attached so as to be hooked by the engaging claw part, the band piece can be easily attached. It is. As described above, according to the present invention, it is possible to easily perform the pipe installation work even in a narrow work space.
