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.
