  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.

  According to the first aspect of the present invention, it is possible to provide a pipe suspension support having high seismic resistance and earthquake resistance even in the event of an earthquake even if the pipe suspension is supported by the long span on the tunnel ceiling.

  By suspending and supporting the piping by alternately using piping suspension supports having two types of support support configurations in the axial direction of the piping, these two types of piping suspension supports were viewed in plan with adjacent ones. In this case, since the support support configuration is symmetrical in the axial direction of the pipe, in addition to the vibration load in the axial direction of the pipe and the vibration load in the orthogonal direction of the pipe simultaneously being generated, it tilts and swings around the axis including twist. Even in the case where load, moment, stress, strain and the like are produced, the two types of support constructions of symmetrical construction cancel each other out in sway in various directions, so that sway can be converged. 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 dealt with, which has a synergetic effect by two types of support and support configuration.

  In particular, it is possible to cope with various vibration directions by the two types of support support configurations of the first support support configuration and the second support support configuration, each of which has a total of three points of suspension support configuration, and the circumstances of the piping attachment surface (The rear attachment surface does not necessarily allow the support rod to be freely attached.) The significant effect is exhibited.

  Furthermore, 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 relatively close to each other, piping support work Exert a significant effect on the efficiency of

  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.

In addition to the above, even in the case where a vibration load that tilts and swings around an axis including a twist is also generated, the action in which two types of support configurations A and B in a symmetrical configuration cancel each other's swing in various directions. It exerts an effect and can converge the shaking. Therefore, even in the case of suspension support for piping in long spans or ultra-long spans, the loads applied to a plurality or a large number of piping supports 1 1 1... Are synchronized and amplified. It has the synergetic effect by the two specific types of support support composition concerning the present invention that it can control and it is hard to produce distortion and breakage in piping support 1.

However, it is possible to use various types of piping bands known in this art as piping bands of this type and having various specifications and materials without particular limitations. For example, it may be a piping band which has a connection part of a combination type composition, and may be a lantern type piping band formed from one annular beltlike plate material.
