  When a plurality of or a plurality of piping supports of the same configuration are suspended and supported using a long span, vibration load in the axial direction of the pipe and vibration load in the orthogonal direction of the pipe axis simultaneously occur when vibration such as earthquake occurs. In addition to twisting, it also causes loads, moments, stresses, strains, etc. that tilt and swing in the direction of the axis, including twisting, and in many cases it is not possible to converge swings, The load, moment, stress, strain, etc. applied to each piping support may be synchronized and amplified, so it is easy to cause distortion or breakage in the piping support, and it is known that problems are likely to occur in terms of earthquake resistance. The

Therefore, an object of the present invention is to provide a pipe suspension support having high seismic resistance and earthquake resistance at the time of earthquake even if the pipe suspension is supported by a long span on a tunnel ceiling.
In the present invention, “seismic” and “seismic” include “anti-vibration” and “anti-vibration”.

  The present invention which solves the above-mentioned subject has the following composition.

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, having a synergetic effect by the two specific support support configurations according to the present invention There is.

  In particular, the adoption of the usual one-point suspension support configuration can cope with various vibration directions, and the cost and piping mounting surface circumstances (the piping mounting surface is not necessarily capable of mounting the support rod Exert a significant effect that takes account of

  In addition, piping having a support support configuration similar to that of the present invention by adding the above-described two types of support support configurations to existing piping equipment having a usual one-point suspension support configuration by a suspension bolt and a piping support band. It can also be a suspension support. In this case, the existing one-point suspension support structure can be regarded as the one-point suspension support structure of the present invention. Also, all of the configurations of the present invention can be added between existing single point suspension support configurations. That is, in the present invention, at least one pipe hanging support having a one-point hanging support structure disposed between can be one, one, two or more, or mixed. Good.

  By the above effects, not only the piping support structure such as the piping support and the suspension bolt but also distortion, damage, breakage, etc. of the piping itself, the connecting portion of the piping, and the joint portion can be remarkably suppressed. Is particularly useful for lifelines represented by water pipes and the like that affect the entire system.

  According to the second aspect of the present invention, since it can be manufactured using a general assembly type piping support band, it can be provided easily and at low cost.

  According to the third aspect of the present invention, since it can be manufactured using a general lantern type piping support band, it can be provided easily and at low cost.
