Description

The present invention relates to a pipe suspension support structure including a plurality of pipe suspension supports, and in particular, a long span extending from several meters to several tens of meters on various mounting surfaces such as ceiling slabs and tunnel ceilings. It is related with the suspension support structure of piping which comprises a plurality of piping suspension supports which are suspended and supported by.

  In order to suspend and support various pipes on a mounting surface such as a ceiling slab or a tunnel ceiling, for example, as shown in Patent Documents 1 to 3 and the like, a support structure including a suspension bolt and a piping band is used as a set. A suspension support having the same configuration, or a suspension support having the same configuration in which one or two suspension support rods provided obliquely are further added, is a few meters to a few tens of meters. This is done by arranging a plurality at intervals.

  Even if the above suspension support structure is a suspension support in a very long span such as a pipe in a tunnel extending over several hundreds of meters to several hundreds of meters or more, the pipe support having the same structure as described above is used. This is done by using a large number.

  When multiple or many pipe supports with the same configuration are suspended and supported in a long span, vibrations in the direction of the pipe axis and vibrations in the direction perpendicular to the pipe axis are generated simultaneously when vibration such as an earthquake occurs. In addition, it may cause loads, moments, stresses, strains, etc. that tilt and oscillate in the direction around the axis including torsion. It can be seen that loads, moments, stresses, strains, etc. applied to individual pipe supports may be amplified in synchronism, and the pipe supports are likely to be distorted and damaged, and problems are likely to occur in terms of seismic strength. It was.

Accordingly, an object of the present invention is to provide a pipe suspension support structure including a plurality of pipe suspension supports having high earthquake resistance and earthquake resistance even in the case of pipe suspension support in a long span to a tunnel ceiling.

[Definition of “Direction in Suspension Support Structure for Piping”]
In the suspended support structure for piping, one end of the pipe when facing one end side of the pipe held and supported by a plurality of pipe supports is the front, the left side of the front of the pipe is the left, The right side of the front of the pipe is the right, the front side in the pipe axis direction is the front, and the other end direction of the pipe, which is the back side in the pipe axis direction, is the rear.

Piping can be held by combining the two band holding portions with a left locking portion connected to one end of each of the two band holding portions, and a right locking portion at each other end. 2. A pipe suspension support structure comprising the plurality of pipe suspension supports according to 1 above, wherein:

According to the first aspect of the present invention, a pipe suspension comprising a plurality of pipe suspension supports having high earthquake resistance and earthquake resistance even in the case of pipe suspension support in a long span to a tunnel ceiling. A support structure can be provided.

  Pipe suspension having two types of slanted two-point suspension support configurations (first support support configuration / second support support configuration) and a pipe suspension having a one-point suspension support configuration in the pipe axis direction By adopting a configuration in which the support tools are alternately suspended while sandwiching the support tools, the pipe suspension supports having two types of slanted two-point support configurations adjacent to each other with the one-point support configuration sandwiched therebetween. When viewed from above, the support structure is a slanting two-point suspension that is symmetrical in the pipe axis direction. Therefore, in addition to the simultaneous occurrence of vibration load in the pipe axis direction and vibration load in the direction perpendicular to the pipe axis, Even when a tilting, oscillating load, moment, stress, strain, etc. occur in the direction, the two diagonal 2-point suspension support configurations with symmetrical configurations cancel out each other in various directions. To demonstrate the ability to converge . Therefore, even if it is a pipe suspension support in a long span, it can be suppressed that the load, moment, stress, strain, etc. applied to a plurality or a plurality of pipe supports are synchronized and amplified. It has the effect that distortion and breakage hardly occur in the pipe support. In addition, even if the incident direction of the seismic wave changes due to the difference in the epicenter during an earthquake, it is possible to cope with various vibration directions, and the synergistic effect by the two specific two-point slanted support structure according to the present invention. have.

  In particular, since the attachment 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 is exhibited in terms of the ability of pipe support work. Furthermore, by adopting a normal one-point suspension support structure, it is possible to cope with various vibration directions and the circumstances of the pipe mounting surface (the pipe mounting surface is not necessarily capable of mounting a support rod freely. Exhibits a significant effect considering

  In addition, by adding the above-described two types of pipe suspension support tools having two oblique suspension support configurations to existing piping equipment having a normal one-point suspension support configuration using suspension bolts and pipe support bands. It can also be set as the piping suspension support tool which has the suspension support structure similar to this invention. In this case, the existing one-point suspension support configuration can be regarded as the one-point suspension support configuration of the present invention. Moreover, all the configurations of the present invention can be added between the existing one-point suspended support configurations. That is, in the present invention, at least one pipe suspension support having a one-point suspension support structure disposed between them is sufficient, even if there is one, two or more, or a mixture. Good.

  As a result of the above effects, not only the pipe support structure such as the pipe support and suspension bolts, but also the piping itself, pipe connections and joints, distortion, damage, breakage, etc. can be remarkably suppressed. Is particularly useful for lifelines such as water pipes that affect the entire system.

  According to the second aspect of the present invention, since a pipe support band formed by combining two semicircular bands facing each other can be used as it is, it can be provided easily and at low cost.
