Therefore, even in the case of the suspension suspension support in the long span, it is possible to suppress that the load, the moment, the stress, the strain and the like applied to a plurality or a plurality of piping supports are synchronized and amplified. It has the effect that distortion and breakage do not easily occur in the piping support. In addition, even if the incident direction of the seismic wave is changed due to the difference of the hypocenter at the time of earthquake, various vibration directions can be coped with, and the synergetic effect by the two kinds of oblique single point suspension support configurations according to the present invention have.

  In particular, the adoption of two types of support support configurations of the pipe suspension support having the left support support configuration and the pipe suspension support having the right support support configuration and the usual one-point suspension support configuration It exerts a significant effect in consideration of the cost aspect that it can cope with the vibration direction and the circumstances of the piping mounting surface (the piping mounting surface is not necessarily able to freely attach the support rod).

  In addition, by adding the above-described two types of diagonal one-point suspension support configuration to the existing piping installation having the usual one-point suspension support configuration by the suspension bolt and the piping support band It is also possible to use a piping suspension support having an oblique one-point suspension support configuration similar to that of the present invention.
