[Definition of “Direction in Suspension Support Structure for Piping”]
In the suspended support structure for piping, one end of the pipe when facing one end side of the pipe held and supported by a plurality of pipe supports is the front, the left side of the front of the pipe is the left, The right side of the front of the pipe is the right, the front side in the pipe axis direction is the front, and the other end direction of the pipe, which is the back side in the pipe axis direction, is the rear.

A pipe suspension support structure comprising the plurality of pipe suspension supports according to 1 above.

According to the first aspect of the present invention, a pipe suspension comprising a plurality of pipe suspension supports having high earthquake resistance and earthquake resistance even in the case of pipe suspension support in a long span to a tunnel ceiling. A support structure can be provided.

  By suspending and supporting the pipes by alternately using the pipe suspension supports having two types of support support configurations in the pipe axis direction, the two types of pipe suspension supports are viewed in plan with each other adjacent to each other. Since the support support structure is symmetrical in the pipe axis direction, the vibration load in the pipe axis direction and the vibration load in the direction perpendicular to the pipe axis are generated at the same time, and tilt and swing in the direction around the axis including torsion. Even when a load, moment, stress, strain, or the like occurs, the two types of support configurations having symmetrical configurations can exhibit the effect of canceling each other in various directions, and the swing can be converged. Therefore, even if it is a pipe suspension support in a long span, it can be suppressed that the load, moment, stress, strain, etc. applied to a plurality or a plurality of pipe supports are synchronized and amplified. It has the effect that distortion and breakage hardly occur in the pipe support. Moreover, even if the incident direction of the seismic wave changes due to the difference in the epicenter during an earthquake, it has a synergistic effect by the two types of support support configurations that can cope with various vibration directions.

  In particular, the cost and pipe installation situation that various vibration directions can be dealt with by the two types of support support configurations, the first support support configuration and the second support support configuration, which are each a three-point suspension support configuration. (The back mounting surface does not always allow the support rod to be freely mounted).

  Further, since the mounting surfaces of the left front suspension support rod 6 and the left rear suspension support rod 7 and the right front suspension support rod 8 and the right rear suspension support rod 9 are located relatively close to each other, the pipe support work It shows a significant effect in terms of efficiency.

  As a result of the above effects, not only the pipe support structure such as the pipe support and suspension bolts, but also the piping itself, pipe connections and joints, distortion, damage, breakage, etc. can be remarkably suppressed. Is particularly useful for lifelines such as water pipes that affect the entire system.

  According to the invention shown in claim 2, since it can be manufactured using a general assembly type pipe support band, it can be provided easily and at low cost.

  According to the invention shown in claim 3, since it can be manufactured using a general lantern type pipe support band, it can be provided easily and at low cost.
