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 two-point suspension support configurations (left support support configuration and right support support configuration) is suspended in the piping axis direction by one-point suspension support configuration By adopting a configuration in which the support members are alternately hung in a state in which the support is sandwiched, the pipe suspension supports having two types of diagonally suspended support configurations adjacent to each other with the one-point suspended support configuration in plan view Since the diagonal two-point suspension support configuration is symmetrical in the pipe axis direction when carrying out, in addition to the vibration load in the pipe axis direction and the vibration load in the pipe axis orthogonal direction simultaneously being generated, Even when tilting, swinging load, moment, stress, strain, etc. are generated, the two diagonal two-point suspension support configurations of the symmetrical configuration mutually cancel out the swing in various directions. Can converge the shakingTherefore, 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, and the synergetic effect by the two kinds of two diagonal suspension support configurations according to the present invention have.

  In addition, by adding the above-described two types of diagonal suspension supporting structure having diagonal two points suspension to the existing piping installation having a usual one point suspension supporting configuration by the suspension bolt and the piping support band It is also possible to provide a pipe suspension support having an oblique two-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.

Since each can be engaged and connected indirectly via the connecting plate members, multiple point suspension support can be obtained in the state of exhibiting anti-vibration properties.

  According to the invention as set forth in claim 3, the left locking portion is a left front suspension support rod / left rear suspension support rod, and the right locking portion is a right front suspension support rod / right rear suspension support rod. Since each can be directly engaged and connected, multiple point suspension support can be obtained in a state of exhibiting anti-vibration (shockproof) performance.

  According to the invention described in claim 4, the upper connecting plate and the lower connecting plate consisting of two plate members are connected to each of the left locking portion and the right locking portion in a state where one end is superposed, By engaging and connecting each suspension support rod to the other end of the connection plate and the lower connection plate, a multipoint suspension support can be obtained in a state of exhibiting anti-vibration (shockproof) performance. 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.
