According to the first aspect of the present invention, the suspension of piping having a plurality of piping suspension supports having high seismic resistance and earthquake resistance even in the event of an earthquake even if the piping suspension is supported by the long span to the tunnel ceiling A support structure can be provided.

  In particular, a piping suspension support having two types of diagonal three-point suspension support configurations (first support support configuration and second support support configuration) is configured as a piping having one point suspension support configuration between in the piping axial direction. A piping suspension support having two types of diagonal three-point suspension support configurations adjacent to each other across a one-point suspension support configuration by adopting a configuration in which the suspension supports are alternately suspended in a state in which the suspension support is sandwiched. Since the diagonal three-point suspension support configuration is symmetrical in the pipe axis direction when viewed in plan view, in addition to the simultaneous occurrence of the vibration load in the pipe axis direction and the vibration load in the pipe axis orthogonal direction, twisting is included. Even when a load, a moment, a stress, a strain, etc. that tilts or swings in the direction around the axis are also generated, the two diagonal three-point suspension support configurations having symmetrical configurations cancel each other's sway in various directions. Demonstrate the effect and make the shake converge It can be. 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. Moreover, 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 two kinds of oblique three-point suspension support configuration according to the present invention have.

  In addition, by adding the above-described two types of diagonal three-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 three-point suspension support configuration similar to that of the present invention. 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, the left locking portion of the first support support structure is suspended to the left front suspension support rod / left rear suspension support rod, and the right locking portion of the second support support configuration is suspended to the right front. Since the lower support rod and the right rear suspension support rod can be engaged and connected indirectly via the connection plate members, multiple point suspension support can be obtained in the state of exhibiting anti-vibration properties .

  According to the third aspect of the present invention, the left locking portion of the first support support structure is suspended to the left front suspension support rod / left rear suspension support rod, and the right locking portion of the second support support configuration is suspended to the right front. Since the lower support rod and the right rear suspension support rod can be directly engaged and connected to each other, multiple point suspension support can be obtained in the state of exhibiting anti-vibration (shockproof) performance.

  According to the invention as set forth in claim 4, the upper connecting plate and the lower connecting plate consisting of two plate members are provided for each of the left locking portion of the first support support configuration and the right locking portion of the second support support configuration. By connecting one end in a polymerized state and engaging and connecting each suspension support rod to the other end of the upper connection plate and the lower connection plate, multiple points are suspended in the state of exhibiting anti-vibration (vibration) Lower support is obtained. Moreover, since the upper connecting plate and the lower connecting plate can change the polymerization angle of the two sheets when one end is polymerized according to the angle of the diagonal suspension support of the suspension support rod, the more stable state Multiple point suspension support is obtained.

  According to the invention as set forth in claim 5, since the upper connecting plate and the lower connecting plate are configured using plate members having the same configuration completely, without paying attention to the upper / lower relationship of overlaying the two sheets, either is above or below It functions as a connecting plate member. Furthermore, in the case of the manufacturing, since the manufacturing equipment such as a mold may be one kind, the production efficiency is high, the manufacturing cost can be reduced, and only one type of plate member is manufactured. Delivery management is easy.

  According to the invention as set forth in claim 6, the bolt is inserted from the through hole even if the nut is removed by attaching the dropout preventing tool such as a clip to the bolt inserted through the through hole of the upper connecting plate and the lower connecting plate. It can prevent falling off. Therefore, the workability in the mounting operation is good, and it is possible to suppress the dropping or loss of parts such as bolts, which contributes not only to high working efficiency but also to improvement in safety.

  According to the seventh aspect of the present invention, a pipe support band formed by combining two opposing semicircular shaped bands can be used as it is, and can be provided easily and at low cost.
