  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.

2. Each band holding portion of the pipe suspension support having the first support support configuration and the pipe suspension support having the second support support configuration has two semicircular band holding portions facing each other in a circular shape The piping can be held by combining, and the left locking portion is provided in a state of being connected to one end of each of the two band holding portions, and the right locking portion is fixed to the other end of each of the two band holding portions. The pipe suspension support according to the above 1, characterized in that it is provided in a state where it is connected in series.

  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.

  A piping suspension support having two types of diagonal two-point suspension support configurations (first support support configuration and second support support configuration) is suspended in the piping axis direction by a piping suspension having one point suspension support configuration therebetween The piping suspension supports having two kinds of diagonal two-point suspension support configurations adjacent to each other across the one-point suspension support configuration by having the configuration in which the suspension is alternately disposed in a state where the support is sandwiched. Since the diagonal two-point suspension support configuration is symmetrical in the pipe axis direction when viewed from above, in addition to the vibration load in the pipe axis direction and the vibration load in the pipe axis orthogonal direction being generated simultaneously, around the axis including twist Even in the case where load, moment, stress, strain, etc. which tilt in the direction are also generated, the operation effect is such that the two types of diagonal two point suspension support configurations of symmetrical configuration mutually cancel swing in various directions. It can be used to make the swing converge . 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, and the synergetic effect by the two kinds of two diagonal suspension support configurations according to the present invention have.

  In particular, since the mounting surfaces of the left or right front suspension support rod and the left or right rear suspension support rod are relatively close to each other, a significant effect can be obtained in terms of the ability to support piping. Furthermore, 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 freely mounting the support rod Exert a significant effect that takes account of

  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 use a piping suspension support having a suspension support configuration similar to that 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.
