A support structure can be provided.

  By suspending the pipe suspension support tool having two types of support support structures alternately in a state where the one-point suspension support structure is sandwiched between them in the pipe axis direction, the one-point suspension is provided. Since the pipe suspension supports having two types of support support structures adjacent to each other with the support structure in plan view are symmetrically supported in the pipe axis direction, the vibration load in the pipe axis direction is orthogonal to the pipe axis. In addition to the simultaneous occurrence of vibration loads in the direction, even if there is a load, moment, stress, strain, etc. that tilt and swing around the axis including torsion, the vibration in various directions is symmetrical The two types of support configurations can exert the effect of canceling each other, and the shaking 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 specific support support configurations according to the present invention that can deal with various vibration directions.
