Description

[Detailed description of the invention] This invention relates to a support structure for piping.

FIGS. 1 to 3 show support structures for piping that have been conventionally employed.

In the piping support structure shown in FIG. 1, a steel pedestal 3 in which the lower part of a sliding material 2 is embedded is placed on a pedestal 1, and a piping 4 is placed on top of the sliding material 2. , the piping 4 is fixed to the pedestal 1 together with the pedestal 3 by U bolts 5. In this pipe support structure, the pipe 4 is in line contact with the sliding member 2 in its axial direction. Therefore, in this pipe support structure, when a lateral load is applied to the pipe 4 due to wind pressure, etc., the U bolt 5
Not only is there a risk of the U-bolt 5 breaking, stress is likely to be concentrated on the part of the pipe 4 that contacts the sliding material 2, that is, the small part that is in line contact, and the large-diameter pipe It is not suitable for supporting such heavy piping. In addition, with this piping structure,
Since the piping 4 is in contact with the sliding material 2 over its entire length in the axial direction, the angular displacement of the piping 4 is restricted and a bending load is applied to the frame 3, so it is not suitable for long-span piping. do not have.

In the piping support structure shown in FIG.
A pedestal 12 having a curved receiving surface is disposed on the top, and a sliding sheet 13 is provided on the receiving surface of the pedestal 12.
is attached, and the piping 14 is placed on the sliding sheet 13, and the piping 14 is fixed to the pedestal 11 together with the pedestal 12 using U bolts 15. In this piping support structure, since the receiving surface of the pedestal 12 is curved, the piping 14 comes into contact with the sliding sheet 13 over almost the entire surface thereof. Therefore, in this piping support structure,
Even if a lateral load is applied to the piping 14 due to wind pressure or the like, the pedestal 12 receives a portion of the load, which prevents the risk of breaking the U-bolt 15. However, against angular displacement of the piping 14, Similar to the one in FIG. 1, no consideration is given to this at all.

In addition, in the piping support structure shown in FIG.
At the same time, a sliding sheet 23 is adhered to the receiving surface of this pedestal 22, and the piping 24 is placed on the sliding sheet 23, and the piping 24 is attached to the pedestal 22 and the pedestal using U-bolts 25. It is fixed at 21. Therefore, in such a pipe support structure, the deformation of the pedestal 22 due to the weight of the pipe 24 is concentrated locally, causing a misalignment between the sliding sheet 23 and the pedestal 22, and the sliding sheet 23 is likely to peel off. . Furthermore, when a lateral load is applied to the piping 22 due to wind pressure or the like, the pedestal 22 cannot support the load, and the load is placed on the U bolt 25.
There is a risk that it may break.

This idea was made in order to solve the above-mentioned problems. A cradle is placed on the pedestal, the piping is placed on the cradle, and the piping is connected with U-bolts. In the piping support structure fixed to a pedestal, the pedestal includes a rigid block whose lower surface is in contact with the upper surface of the pedestal and whose upper surface is formed into a curved surface substantially concentric with the piping; It consists of an elastomer block whose upper surface is formed into a curved surface that is in contact with a curved surface and whose upper surface is approximately concentric with the piping, and a synthetic resin sheet that is adhered to the upper surface of the elastomer block. In the direction cross section, a groove is formed at the center of the lower surface, and slopes are formed at both ends of the upper surface, and a steel plate having thick parts at both ends is buried almost entirely inside the groove, It is characterized in that a groove is fitted into the upper part of the rigid block.

Next, this invention will be explained with reference to the drawings.

FIG. 4 is a front view showing one embodiment of the piping support structure of this invention, and FIG.
FIG.

The support structure for this piping consists of a pedestal in which an elastomer block 43 is placed on a rigid block 42 placed on a pedestal 41, and a synthetic resin sheet 44 is glued onto the elastomer block 43. , piping 45 is placed on the synthetic resin sheet 44.
and then connect the piping 45 to the elastomer block 43 and the rigid block 42 using the U bolts 46.
It is also fixed to the pedestal 41.

The rigid block 42 is made of metal, synthetic resin, or the like, and has a curved upper surface substantially concentric with the pipe 45. This rigid block 42 is fixed to the pedestal 41 with bolts or the like. As shown in FIG. 5, the elastomer block 43 has a concave groove 43a formed at the center of the lower surface and slopes 43b at both ends of the upper surface in the axial cross section. A steel plate 47 is buried inside the elastomer block 43 over almost the entire area. The steel plate 47 has thick portions 47a at both ends. This thick portion 47a is formed over the entire length of the steel plate 47 along the circumferential surface of the pipe 45 shown in FIG. As shown in FIG. 4, the elastomer block 43 configured in this manner is entirely curved along the circumferential surface of the pipe 45, and therefore has an upper surface with a curved surface that is approximately concentric with the pipe 45. is doing. This elastomer block 43 has a concave groove 43a that is connected to the rigid block 4.
It is attached to the second autopsy. In addition, the synthetic resin sheet 4 bonded to the elastomer block 43
4 is made of a material with low frictional resistance.

The piping 45 in this embodiment is brought into close contact with the entire surface of the synthetic resin sheet 44 due to the elasticity of the elastomer block 43, and is also reliably supported by the steel plate 47 and the rigid block 42. Therefore, even if a lateral load due to wind pressure or the like acts on the pipe 45, a part of the load is absorbed by the rigid block 42, and the U-bolt 46 is not overloaded. Moreover, even if an angular displacement occurs in the pipe 45,
The displacement is allowed by the elastomer block 43. This is because the elastomer block 43 easily deforms in response to the angular displacement of the pipe 45. Furthermore, in the pipe support structure of the embodiment, the elastomer block 43 is fitted onto the rigid block 42 so as to extend from the rigid block 42 in the pipe axis direction, and the extended portion is attached to the steel plate 4.
7, the pipe 45 is supported by a wider surface, and the synthetic resin sheet 4
Since the end portion of the upper surface of the pipe 4 in the tube axis direction is inclined along the slope 43b of the elastomer block 43, it is possible to better cope with angular displacement of the pipe 45.

As explained above, according to this invention, it is possible to construct a long-span pipe, providing stable support for the pipe over a long period of time, and further reducing the weight.
