  According to the third aspect of the present invention, the left front suspension support rod / left rear suspension support rod is attached to the left locking portion of the first support support configuration, and the right front suspension suspension is mounted to the right locking portion of the second support support configuration. Since the lower support rod and the right rear suspension support rod can be directly engaged and connected to each other, a multipoint suspension support in a state in which vibration isolation (seismic isolation) performance is exhibited is obtained.

  According to the fourth aspect of the present invention, the upper connection plate and the lower connection plate formed of two plate-like members are provided on 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 superposed state and engaging and connecting each suspension support rod to the other end of this upper connection plate / lower connection plate, multiple points are suspended in a state where anti-vibration properties are exhibited. Lower support is obtained. Moreover, the upper connecting plate and the lower connecting plate can change the overlapping angle of the two sheets when one end is overlapped according to the angle of the diagonally suspended support of the suspended support rod, so that in a more stable state Multiple point suspension support is obtained.

  According to the fifth aspect of the present invention, since the upper connecting plate and the lower connecting plate are configured using plate members having exactly the same structure, either the upper connection plate or the lower connection plate can be used without paying attention to the vertical relationship of layering these two sheets. Functions as a connecting plate member. In addition, when manufacturing it, a single type of manufacturing facility such as a mold is sufficient, so that production efficiency is high, manufacturing costs can be reduced, and only one type of plate member is manufactured, so inventory management, order receipt management, Delivery management is easy.

It is set as appropriate according to various conditions such as the hanging angle of the flange 9.

  In the present embodiment shown in FIGS. 1 to 4, the left latching portion 14 and the right latching portion 15 are formed by holding the plate material that is the same material and separate from the band holding portion 11. By attaching to the formation position of the part 11 by welding, the left latching | locking part 14 and the right latching | locking part 15 are each formed.

As shown in FIGS. 1 and 2, the pipe suspension support 1 of the present invention having the above-described configuration is as shown in FIGS.
The pipe suspension support 1 having the first support support configuration A shown in FIG. 3 is attached to the suspension bolt 3 whose one end is fixed to the mounting surface 2 via the suspension connection member 31 such as a tangle. It is supported by the bolts and nuts 16 so as to be suspended and supported on the mounting surface 2 (first point of suspension support).

  By suspending and supporting the pipe P by alternately using the pipe suspension support 1 having the above configuration, that is, the two types of support support structures A and B in the pipe axis direction, these two types (A and B) are provided. Since the pipe suspension support tool 1 has a support support structure that is symmetrical in the pipe axis direction when viewed in plan from each other, the vibration load in the pipe axis direction and the vibration load in the direction perpendicular to the pipe axis are generated simultaneously. In addition, even when a vibration load that tilts and swings in the direction around the axis including torsion is generated, the two support configurations A and B having symmetrical configurations cancel out each other in various directions. The effect is demonstrated and the shaking can be converged. Therefore, even in the case of pipe suspension support in a long span or an ultra-long span, the load applied to a plurality or a large number of pipe supports 1. It has a synergistic effect by two specific types of support support configurations according to the present invention that can be suppressed and that the pipe support 1 is less likely to be distorted or damaged.
