  First, a first embodiment of a vibration isolating structure for a pipe support according to the present invention (hereinafter sometimes simply referred to as a vibration isolating structure) will be described with reference to FIGS.

  As shown in FIGS. 1 and 2, the vibration-proof structure 1 has a piping support in which a pipe P is attached to a mounting surface (hereinafter, simply referred to as a mounting surface) 2 such as a ceiling, a wall, or a floor in the pipe axis direction. 10, which is supported at an angle, and is a support location for the pipe P that is one end of the diagonal support 10 (location indicated by an arrow A) and a support for the mounting surface 2 that is the other end of the diagonal support 10. A location (location indicated by an arrow B) is a pivot mounting portion 3. The support portion A for the pipe P is held and supported by a general pipe support 4 such as a publicly known pipe support band.

  The oblique support 10 includes a long rod 11 and a long rod fixing portion 12 that clamps and fixes an end portion of the long rod 11, and the long rod fixing portion 12 is the pivot mounting portion 3. It is the structure fixed so that pivot support was possible.

  When the long rod 11 is a tubular member as in this embodiment shown in FIGS. 3 and 4, the long rod 11 is clamped and fixed by the long rod fixing portion 12. It is preferable that the surface and the outer peripheral surface are clamped and fixed, and the fixing of the clamp is preferably performed by tightening with a fixing means 13 such as a bolt.

  FIG. 3 shows the pivot mounting portion 3 used for the support portion B for the mounting surface 2, and FIG. 4 shows the one used for the support portion A for the pipe P.

  As shown in FIG. 3, the pivot mounting portion 3 used at the support portion B for the mounting surface 2 is fixedly mounted on the mounting surface 2 by a fixing member 31 such as an anchor. The diagonal support 10 (the long rod 11 and the long rod fixing portion 12) pivotally attached to the pivot attachment portion 3 pivots and pivots in the direction of the arrow X about the pivot shaft 32 as a pivot axis.

  As shown in FIG. 4, the pivot mounting portion 3 used in the support portion A for the pipe P has a portion in which a long rod fixing portion 12 that clamps and fixes the long rod 11 of the oblique support 10 is connected. The pivot support part 3 is configured, and the pivot support part 3 holds and supports the pipe P. The band end 41 of the pipe support 4 is provided with a bolt 42 serving as a pivot axis in the direction of the arrow Y. It pivots.

  Since both the pivot mounting portions 3 and 3 used for the support portions A and B are pivoted in the pipe axis direction, the pipe P is supported from an oblique direction while absorbing vibration in the pipe axis direction. The pipe P can be supported in a vibration-proof manner. Therefore, even if it is used for a building with a structure that allows or absorbs shaking due to an earthquake, such as a building with a rigid structure, a flexible structure, a seismic isolation structure, or a vibration control structure, Even if the building frame is distorted or bent due to the shaking, these distortions and deflections can be absorbed by the support point B for the mounting part with the building frame or the support point A for the piping P, so that partial stress concentration The occurrence of breakage due to can be suppressed.

The pivot support part 3 and the oblique support 10 are fixedly clamped in the same manner as in the first embodiment.

  The pivot mounting structure at the support location D is the same as that of the configuration used at the support location B in Example 1 except that the configuration is changed from the pipe axis direction to the pipe axis orthogonal direction.

  With the above configuration, the piping P pivotally attached at the support location C and the support location D has the pivot rotation direction in the direction perpendicular to the pipe axis. The pipe P can be supported in an anti-vibration manner while absorbing the shaking. Therefore, even if it is used for a building with a structure that allows or absorbs shaking due to an earthquake, such as a building with a rigid structure, a flexible structure, a seismic isolation structure, or a vibration control structure, Even if the building frame is distorted or bent due to the shaking, these distortions and deflections can be absorbed by the support points D for the mounting portion with the building frame and the support points C for the piping P, so that partial stress concentration The occurrence of breakage due to can be suppressed.

Also in this fixed portion, the bolt 42 may be pivotally supported around the pivot shaft. By pivoting and rotating the fixed portion at the band end 41, the pivoting rotation is in the direction of the pipe axis. According to such a configuration, in the support portion C, the direction perpendicular to the pipe axis and the direction of the pipe axis are set. Anti-vibration support while absorbing vibration in both directions is possible.
